From cabdaebb72a683ddfce51ebfea88752ce0d851f8 Mon Sep 17 00:00:00 2001 From: Marco Bambini Date: Tue, 27 Jan 2026 15:17:45 +0100 Subject: [PATCH 01/86] Added support for Postgres database (#1) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit * New architecture WP 1 * New architecture WP 2 * WIP 3 * Optimized cloudsync_table_context interaction * New architecture WP 4 * Refactored begin/commit ALTER * New architecture WP 6 * New architecture (WP 5) * Minor changes * New architecture WP 6 * New architecture WP 7 * Small compilation issue fixed * New architecture WP 9 * fix: minor compilation issue * fix: database_* functions must call cloudsync_memory_* functions instead of direct sqlite3_* memory function to support the memory debugger module call cloudsync_memory_mprintf and cloudsync_memory_free instead of direct sqlite3_mprintf and sqlite3_free memory functions from database_create_insert_trigger otherwise the memory debugger would report "Pointer being freed was not previously allocated." * fix(memdebug): fix pointer returned by memdebug_zeroalloc * fix(unittest): avoid a memory leak from do_test_dbutils * test: add unittest target to Makefile Introduces a 'unittest' target to run only unit tests and updates the help output accordingly. * Update unit.c * Refactored SQL in dbutils (related to settings) * Updated static statements in cloudsync.c (WP 1) * Replaced name escape with a function (WP 2) * Completed SQL refactoring * fix: minor compilation issue * test: re-add integration test use `make unittest` to run only the unittest * fix(network): fix the network layer after database-api refactoring * Several compilation warnings fixed * Cleaned-up 64bit types * fix(lcov): exclude sql_sqlite.c from code coverage, it just contains query strings * Update cloudsync_sqlite.c * Use int64_t for version variables in network.c Replaces sqlite3_int64 with int64_t for new_db_version and new_seq variables to standardize integer type usage and improve portability. Was giving a compile error on linux musl * Update vtab.c * chore: remove warnings * Update vtab.c * test: fix compile errors on linux musl * Replaced all %lld (except one) * fix: minor compilation error * refactor: new directory structure to separate multi-platform code from database-specific implementations Refactor the codebase to separate multi-platform code from database-specific implementations, preparing for PostgreSQL extension development. vtab.c/h has been renamed to sqlite/cloudsync_changes_sqlite.c/h * fix(workflow): add CFLAGS for CURL Android builds and clean up Android build files * fix(android): add -fPIC to CFLAGS * fix(android): use OpenSSL specific version * fix(android): update OpenSSL install path to a local one, instead of a system wide path * db_version must be int64_t in network.c * fix: avoid crash on postgres when these functions are called with NULL values for db and data * improved error logs, fix some debug messages * New postgresql extension WIP 1 * Updated SQL_DATA_VERSION and added a new sql_build_select_nonpk_by_pk function to database.h * fix: remove obsolete property * chore * fix: improved SQL queries (WIP) * implement SQL_SCHEMA_VERSION with app_schema_version table and event trigger * fix: fix PG SQL queries used in cloudsync_init * fix: avoid a segfault crash in cloudsync_init Allocate in TopMemoryContext to survive SPI cleanup * test: calling twice the cloudsync_init function on postgresql is failing (WIP) * Code simplification and memory cleanup (wp) * Minor fixes * test: add debug PostgreSQL devcontainer and Docker setup Introduces a VS Code devcontainer configuration for PostgreSQL development with CloudSync, including a debug Dockerfile, docker-compose file, and Makefile changes to support debug builds. This setup enables easier debugging and development of the CloudSync extension for PostgreSQL in a containerized environment. * chore: update docker/README.md with VS Code Dev Container Debugging instructions * test: add .vscode/launch.json with the "Attach to Postgres (gdb)" configuration * Added more explicit string_dup functions * Fixed network * Error returned by sqlite3_extension_init function must be dynamically allocated * test: add debug symbols and src code of postgresql server to dev container * fix: add SPI_connect and SPI_finish to _PG_init function * dbutils.c removed db_t * Minor changes * Refactoring (wp) * Refactoring (wp) * Refactoring (wp) * Refactoring (wp) * Refactoring (wp) * Refactoring (wp) * Refactoring (wp) Removed cloudsync_private.h and db_t * Refactoring (pg wp) * Various PostgreSQL fixes * Refactoring PG code * chore: minor fixes for when debug macros are enabled * fix: use global memory when the DBFLAG_PERSISTENT flag is set to avoid crash for double free * fix(cloudsync): guard against errmsg aliasing in error formatting It was fixed by snapshotting db_error into a local buffer when it aliases data->errmsg, then formatting from the copy. This avoids undefined behavior. * fix(postgresql): fix error message in cloudsync_init_internal, the error message must be copied before database_rollback_savepoint reset the error message * fix(postgresql): skip SPI_cursor_open for non-cursorable plans - avoid trying to open a cursor on INSERT/UPDATE/DELETE plans without RETURNING - use SPI_is_cursor_plan to decide whether to use a portal or execute once - fixes “cannot open INSERT query as cursor” during cloudsync_init paths (for example with SQL_INSERT_SITE_ID_ROWID) * Minor fixes * Improved SPI’s memory ownership rule and prevents accumulation across large result sets * dbmem apis now use pg native memory functions * More memory related fixes * Apparently repalloc doesn't like a NULL ptr * Update database_postgresql.c * get_cloudsync_context must be allocated in a global context * Revert "get_cloudsync_context must be allocated in a global context" This reverts commit 4e614f1522cdae411abd2dec46bfa17b8b2468b6. * Revert "Update database_postgresql.c" This reverts commit 13367c1e8958b067351dd2b990c8b0e25669021f. * Revert "Apparently repalloc doesn't like a NULL ptr" This reverts commit ffd587a9987257249f43f953d2328e9e97a28882. * Revert "More memory related fixes" This reverts commit f44c161f2fac205d5aaa99b7f59005f70a901ee2. * Revert "dbmem apis now use pg native memory functions" This reverts commit 4523e4203726183d4ac5f8db18d4f316bc321971. * Several memory related issues fixed * Fixed memory allocations in PG BLOB functions * pgvalue_vec_push can fails (it now return a bool) * Improved memory handling for dbvalue_t * fix(sql_postgresql): fix placeholder for cloudsync_memory_mprintf in SQL_PRAGMA_TABLEINFO_LIST_NONPK_NAME_CID * fix(database_postgresql): refactor error handling in PostgreSQL database functions to always call PG_END_TRY, this fix a SIGSEGV error for corrupted stack * fix(dbutils): dbutils_table_settings_get_value and dbutils_settings_get_value must return NULL in case no rows or error Caller code can check if the return value is NULL or not * fix: remove unnecessary switch to top memory context for text_to_cstring * fix: if databasevm_bind_text size argurmnt is negative, then the length of the string is the number of bytes up to the first zero terminator * refactor(pgvalue): always alloc values owned by pgvalue struct in the PG memory context to simplify the memory management * chore * chore: remove unused SQL queries from sql_postgresql.c * fix(sql_postgresql): fix SQL_PRAGMA_TABLEINFO_LIST_NONPK_NAME_CID * fix(sql_postgresql): SQL_PRAGMA_TABLEINFO_LIST_NONPK_NAME_CID * fix(postgresql): implement triggers and functions called by triggers, fix metatable's schemas, fix cloudsync_pk_encode/decode functions (use bytea instead of text for pk col values) * test(pg smoke test): add tests for cloudsync_pk_encode and for insert/delete triggers and for the content of the metatable * Minor changes * Payload encoding sanity check added * Improved dbutils_settings_get_value * fix(cloudsync_postgresql): cloudsync_init returns the site_id as bytea type * chore * fix(postgresql): lazy-init cloudsync context per call Avoid relcache/snapshot leaks during CREATE EXTENSION by moving SPI-dependent init to normal function calls. Add cloudsync_pg_ensure_initialized helper, drop SPI work from _PG_init, and wire initialization into SQL entry points so context loads on demand. * Improved dbutils_table_settings_get_value * fix: solve a compile error. cloudsync_context is opaque in this compilation unit, so data->site_id isn’t accessible, use the public accessor instead. * feat(postgresql): implement cloudsync_update * chore * fix(postgresql): fix the PG_TRY/PG_CATCH exception stack, must not return inside PG_TRY block * Various improvements to encoding/decoding functions * Improved cloudsync_pg_context_init * Better network memory management * Implemented cloudsync_changes * fix: sql_build_rekey_pk_and_reset_version_except_col has different parameters for sqlite and postgresql * fix(cloudsync_postgresql.c): fix implementation of cloudsync_update aggregate function and cloudsync_delete * ci: add new target to build and run the debug version for vscode and the standalone asan version * fix(cloudsync_postgresql): fix memory context for cloudsync_changes (read) and change the col_value type to bytea to store pk_encoded value preserve SQLite-compatible payloads by encoding `col_value` with the same pk wire format before it reaches the SRF/view layer. With the bytea value for col_value we can reuse the same existing columns from the sqlite extension to encode/decode the type of the value and the value itself, and reuse the same query `SELECT cloudsync_payload_encode(tbl, pk, col_name, col_value, ...) FROM cloudsync_changes`, otherwise we should add a new column for the type and use a cast to the specific type * Added new pk_encode_value * fix(sql_postgresql): fix SQL_BUILD_UPSERT_PK_AND_COL query used for col_merge_stmt * add a skip_decode_idx argument to pk_decode, used in postgresql * fix(cloudsync_postgresql): fix cloudsync_changes_insert_trg to use col_value as bytea with the pk encoded value * test: add read and write tests for cloudsync_changes * Renamed PG changes functions and removed unused variable * No real changes * Improved cloudsync_changes SELECT * Updated cloudsync_changes (wp) * Finished implementing cloudsync_changes * fix(pk): the original blob value for the undecoded col_value for the skipped column was missing the first type byte * fix(pk): add the skip_idx argument for the pk_encode and pk_encode_size just like I already added to pk_decode, needed by cloudsync_payload_encode on postgresql * fix(cloudsync): fix the buffer len value (blen) after decompressing a compressed payload * fix(sql_postgresql): fix the SQL_CLOUDSYNC_UPSERT_RAW_COLVERSION for postgresql * fix(sql_postgresql): fix placeholder from ? to $ notation for postgresql * refactor(postgresql): add pgvalue_free function to make it clear how to free pgvalue object from internal functions * chore * fix(postgresql/coydsync--1.0.sql): fix arguments for cloudsync_payload_encode aggregate function * Update cloudsync--1.0.sql * fix(postgresql): fix cloudsync_changes_insert_trigger for TOMBSTONE rows * fix(postgresql): trying to fix relcache/plancache/snapshot leaks that occurs when an exception is thrown and catched inside cloudsync_changes_insert_trigger (WIP) * test(postgresql/smoke_test): add a test for payload roundtrip to another database * test: minor changes to smoke_test.sql * Added bounds check to pk and checksum to payload * test: update include directive for integration test when run with CLOUDSYNC_LOAD_FROM_SOURCES from Xcode project * Checksum is checked only if payload version is >= 2 * Fixed compilation issue * fix(android): renamed endian.h to cloudsync_endian.h to avoid android ndk clang to have conflicts with sys/endian.h * ci: update the dockerfile configurations to use postgresql 17 instead of 16, the same version used by supabase * build(supabase): build a custom supabase/postgres:17.6.1.071 docker image to be used from the `supabase start` stack * test(postgres/smoke_test): update the test to create different databases to simulate different peers * Several issues fixed and optimizations added (reported by Claude) * skip the schema hash check for now, we cannot compare the hash between sqlite and postgres like we were doing for sqlite * feat(network)!: support the v2 endpoints exposed by the new sqlite-sync-server * fix: free SPI_tuptable (if exists) after each invocation of SPI_execute to avoid memory leaks and to optimize memory usage * fix: update the return type for the cloudsync_payload_apply function, it returns the number of applied rows * Update database_postgresql.c * fix(supabase): prevent a unhealthy status during the restart of the supabase stack The error occurs because the event trigger function inserts into app_schema_version without schema qualification, failing due to missing table in the search_path used by Supabase realtime (which connects to the "postgres" database with a different schema context). Always create app_schema_version in public and updating the function’s insert statement to reference public.app_schema_version * docs(docker/README.md): added a troubleshooting note about the app_schema_version/Realtime migration error * Several memory related issues fixed * fix(network): token size when calling cloudsync_network_set_token before cloudsync_network_init, if the token was greater that 256 chars it was truncated * fix: bind null values for col_value column in INSERT INTO cloudsync_changes with type bytea to avoid "failed to find conversion function from unknown to bytea" error * fix(postgresql): return raw column in SQL_BUILD_SELECT_COLS_BY_PK_FMT instead of the encoded value This query is used during merge conflict resolution to compare local values against incoming changes. Returning encoded bytea caused type mismatches and order-dependent winners in multi-db tests, failing 03_3db_multiple_roundtrip.sql. * test(postgresql): move the smoke test to the test/postgresql dir Also split the smoke test into different test files, all these test files are called by smoke_test.sql * bump version * test(postgresql): new multi-db tests * chore: add docs with analysis on the open issues * test(postgresql): make 02_roundript.sql test executable as a standalone test * Update ISSUE_WARNING_resource_was_not_closed.md * Added support for schema * release wip-pg-extension branch node and expo packages to npmjs with the "pg" tag * renamed workflows for OIDC publishing issues, to revert before merging to main * Added new database_internal_table_exists function to make sure to check for system tables in the public schema (PG only) * fix(workflow): node packages to use pg tagged version * fix(packages/node): wrong fat binary artifact folder * Bump version to 0.9.63 * fix(database_postgresql): fix database_select1_value to make it work with text result of type name (for example the result of SELECT current_schema();) * fix(cloudsync_postgresql): only free quoted identifiers if they're different from the input * test(postgresql): add tests for multi-schema scenario * fix(postgresql): prevent duplicate primary keys when tables exist in multiple schemas When a table name exists in multiple schemas (e.g., public.users and auth.users), SQL queries joining information_schema.table_constraints with information_schema.key_column_usage were returning duplicate primary key columns. Solution: Added "AND tc.table_schema = kcu.table_schema" to all JOIN conditions to ensure primary key information is only retrieved from the target schema specified by cloudsync_schema() or current_schema(). * fix(cloudsync): avoid a crash when setting the cloudsync_set_schema to the the same previous pointer * test(postgresql): improved tests * Added new define for schema literal * fix: skip the decode step regardless of the data type (for the col idx specified by skip_decode_idx) we still need to parse the value depending on the data type to increment the bseek value for the next loop * Several minor issues fixed * Several other issues fixed * Update network.m * fix: preserve prepared plan across databasevm_reset() in PostgreSQL backend Previously, databasevm_reset() called databasevm_clear_bindings() which destroyed the SPIPlanPtr on every reset, forcing a full SPI_prepare on each bind/step cycle. This negated the benefit of caching statements in cloudsync_table_context. Now reset() only clears parameter values while keeping the plan, types, and nparams intact for reuse. Co-Authored-By: Claude Opus 4.5 * Added new CLOUDSYNC_CHANGES_NCOLS constant * database_value_text returns NULL also in PostgreSQL implementation * fix(postgres): fix current memory context to avoid crashes on PG_CATCH, the CopyErrorData func must not be called from a error context * test(postgres): add a test similar to the sport_tracker app * Fixed allocation in value returned after SPI_finish * Updated databasevm_step0, databasevm_step and databasevm_clear_bindings. Fixed warnings in test (due to uint64_t usage in a signed BIGINT) * Fix for 11_multi_table_rounds.sql * Several minor issues fixed * fix(packages/node): broken dynamic import for platform specific package in ESM * test(postgresql): improved test for multi_table_multi_columns_rounds and move the test for repeated_table on multiple schemas to a separated test file * Fixed cloudsync_network_logout * fix(network): cleanup the network configuration during network logout * fix: use the correct schema for previously initialized tables on new connections to the database * test(postgres): build the debug image with no-optimization flag * Fixed some issues related to escaping * Quoting and memory issues fixed Several quoting issues fixed. Added pfree(elems) and pfree(nulls) after the loop to free memory allocated by deconstruct_array. Moved CStringGetTextDatum allocations before PG_TRY and pfree calls after PG_END_TRY. A need_schema_param flag determines whether 1 or 2 Datums are allocated/freed. This ensures the Datum memory is cleaned up on both the success path and the PG_CATCH error path. * Removed unused files * Delete .github/workflows/main.yml * Rename rename_to_main_before_merge_to_main_branch.yml to main.yml --------- Co-authored-by: Andrea Donetti Co-authored-by: Gioele Cantoni Co-authored-by: Claude Opus 4.5 --- .devcontainer/devcontainer.json | 17 + .github/workflows/main.yml | 2 +- .gitignore | 1 -

Database-specific implementations are organized in subdirectories: `src/sqlite/database_sqlite.c` for SQLite, `src/postgresql/database_postgresql.c` for PostgreSQL. All database interactions go through this abstraction layer using: +- `cloudsync_context` - opaque per-database context shared across layers +- `dbvm_t` - opaque prepared statement/virtual machine handle +- `dbvalue_t` - opaque database value handle + +The abstraction exposes: +- Result/status codes (`DBRES`), data types (`DBTYPE`), and flags (`DBFLAG`). +- Core query helpers (`database_exec`, `database_select_*`, `database_write`). +- Schema/metadata helpers (`database_table_exists`, `database_trigger_exists`, `database_count_*`, `database_pk_names`). +- Transaction helpers (`database_begin_savepoint`, `database_commit_savepoint`, `database_rollback_savepoint`, `database_in_transaction`). +- VM lifecycle (`databasevm_prepare/step/reset/finalize/clear_bindings`) plus bind/value/column accessors. +- Backend memory helpers (`dbmem_*`) and SQL builder helpers (`sql_build_*`). + +### CRDT Implementation + +The extension implements four CRDT algorithms for different use cases: + +1. **CLS (Causal-Length Set)** - Default algorithm, balances add/delete operations +2. **GOS (Grow-Only Set)** - Additions only, deletions create tombstones +3. **DWS (Delete-Wins Set)** - Deletions take precedence over additions +4. **AWS (Add-Wins Set)** - Additions take precedence over deletions + +Algorithm selection is per-table via `cloudsync_init(table_name, algo)`. + +### Key Components + +#### Core Sync Engine (`cloudsync.c/h`) + +The main synchronization logic and public API. Key structures: +- `cloudsync_context` - Per-database sync context (site ID, version, sequence counters) +- `cloudsync_table_context` - Per-table sync metadata (algorithm, columns, primary keys) + +Critical functions: +- `cloudsync_init_table()` - Initializes table for sync, creates metadata tables and triggers +- `cloudsync_payload_save()` - Exports changes as binary payload +- `cloudsync_payload_apply()` - Applies incoming changes with CRDT merge logic +- `cloudsync_commit_hook()` / `cloudsync_rollback_hook()` - Transaction hooks for change tracking + +#### Virtual Table (`src/sqlite/cloudsync_changes_sqlite.c`) + +Implements `cloudsync_changes` virtual table (SQLite-specific) that provides a SQL interface to view pending changes: +```sql +SELECT * FROM cloudsync_changes WHERE tbl='my_table'; +``` + +#### Payload Encoding (`pk.c`) + +Efficient binary serialization of database changes: +- Platform-independent (handles endianness with htonl/ntohl) +- Encodes type information + variable-length data +- Minimizes payload size for network transmission +- Supports all SQLite types (integer, float, text, blob, null) + +#### Network Layer (`network.c/h`) + +Built-in synchronization with SQLite Cloud: +- Uses libcurl for HTTPS communication +- Handles authentication (API keys and JWT tokens) +- Implements retry logic and state reconciliation +- Functions: `cloudsync_network_init()`, `cloudsync_network_sync()`, etc. + +#### Database Utilities (`dbutils.c/h`) + +Helper functions for: +- Creating/managing sync metadata tables (`cloudsync_settings`, `cloudsync_table_settings`, etc.) +- Schema validation and sanity checks +- Trigger management for change tracking +- Settings persistence (sync versions, sequences, algorithms) + +#### UUID Generation (`utils.c`) + +Implements UUIDv7 generation optimized for distributed systems: +- Timestamp-based with monotonic ordering +- Globally unique across devices +- Available via `cloudsync_uuid()` SQL function + +### Metadata Tables + +The extension creates internal tables to track sync state: + +- `cloudsync_settings` - Global sync configuration and state +- `cloudsync_table_settings` - Per-table sync configuration +- `cloudsync_site_id` - Unique site identifier for this database +- `cloudsync_schema_versions` - Schema version tracking +- `{table}_cloudsync` - Per-table CRDT metadata (logical clock, site IDs) + +### Change Tracking + +The extension uses SQLite triggers to automatically track all changes: +- INSERT triggers mark new rows for synchronization +- UPDATE triggers record which columns changed and their versions +- DELETE triggers create tombstone records (for most CRDT algorithms) +- Triggers are created/managed by `cloudsync_init()` based on the chosen algorithm + +### Merge Algorithm + +When applying remote changes via `cloudsync_payload_apply()`: + +1. Changes are deserialized from binary payload +2. For each change, CRDT algorithm determines conflict resolution: + - Compares vector clocks (db_version, sequence, site_id) + - Column-by-column merge based on causal ordering + - Handles concurrent updates deterministically +3. Local database updated with winning values +4. Metadata tables updated with merge results + +## Architecture Patterns + +Understanding the architectural patterns helps when modifying or extending the codebase. + +### 1. SQLite Extension Pattern + +The entire system is built as a **loadable SQLite extension**: +- Single entry point: `sqlite3_cloudsync_init()` in `src/sqlite/cloudsync_sqlite.c` +- Registers custom SQL functions during initialization +- Extends SQLite without modifying its core +- Loaded dynamically: `.load ./cloudsync` or `SELECT load_extension('./cloudsync')` + +**Key benefit**: Users add sync to existing SQLite apps by loading the extension and calling setup functions—no application rewrite needed. + +### 2. Shadow Metadata Tables Pattern + +For each synced table (e.g., `users`), the extension creates parallel metadata tables: + +``` +users (user's actual data - unchanged) +users_cloudsync (CRDT metadata: versions, site_ids, per-column logical clock) +``` + +**Benefits**: +- Zero schema pollution—user tables remain unchanged +- Efficient queries like "what changed since version X" +- Metadata separate from application data +- Users can drop sync by removing metadata tables + +### 3. Vector Clock CRDT Pattern + +Each column value carries a **vector clock** for causal ordering: + +```c +// Stored in {table}_cloudsync for each column: +- col_version: Lamport clock for a specific column, used to resolve merge conflicts when syncing databases that have taken independent writes. The primary purpose of col_version is to determine which value "wins" when two different peers update the same column of the same row offline and then merge their changes. The value with the higher col_version is selected as the most recent/authoritative one. +- db_version: Lamport clock for the entire database. This value is incremented with every transaction. +- site_id: UUID identifying which device made the change +- seq: sequence number for ordering changes within same db_version +``` + +**Merge algorithm** (column-by-column): +1. Compare vector clocks between local and remote values +2. Higher version wins (causally later) +3. Same version → use site_id as deterministic tiebreaker +4. No data loss, no manual conflict resolution + +**Why column-level?** Allows merging concurrent updates to different columns of the same row (e.g., User A updates email, User B updates phone—both changes preserved). + +### 4. Trigger-Based Change Tracking Pattern + +All changes captured **declaratively** using SQLite triggers: + +```sql +-- Auto-generated for each synced table +CREATE TRIGGER users_insert_trigger AFTER INSERT ON users +BEGIN + INSERT INTO users_cloudsync (...); -- Record CRDT metadata +END; +``` + +**User experience**: +```sql +-- User just does normal SQL: +INSERT INTO users (id, name) VALUES (cloudsync_uuid(), 'Alice'); +UPDATE users SET email = 'alice@example.com' WHERE id = '...'; +DELETE FROM users WHERE id = '...'; + +-- Triggers automatically capture metadata—no API calls needed +``` + +**Implementation**: Triggers created/destroyed by `cloudsync_init()` / `cloudsync_cleanup()` in `dbutils.c`. + +### 5. Transaction Hook Pattern + +Integrates with SQLite transaction lifecycle via callbacks: + +```c +// Registered during extension initialization: +sqlite3_commit_hook(db, cloudsync_commit_hook, ctx); +sqlite3_rollback_hook(db, cloudsync_rollback_hook, ctx); +``` + +**On commit**: Increment global db_version and seq counters +**On rollback**: Discard any metadata written during failed transaction + +**Why important**: Maintains consistency between user data and CRDT metadata without user intervention. + +### 6. Virtual Table Interface Pattern + +Implements SQLite's virtual table mechanism (`src/sqlite/cloudsync_changes_sqlite.c`) for queryable sync state: + +```sql +-- No actual 'cloudsync_changes' table exists—it's virtual +SELECT tbl, pk, colname, colvalue FROM cloudsync_changes +WHERE tbl='users' AND db_version > 100; +``` + +**Implementation**: +- `xConnect/xDisconnect` - setup/teardown +- `xBestIndex` - query optimization hints +- `xFilter` - execute query over metadata tables +- Results generated on-demand, no storage + +**Benefit**: Standard SQL interface to sync internals for debugging and monitoring. + +### 7. Binary Payload Serialization Pattern + +Custom wire format in `pk.c` optimized for SQLite data types: + +``` +[num_cols:1 byte][type+len:1 byte][value:N bytes][type+len:1 byte][value:N bytes]... +``` + +**Features**: +- Platform-independent endianness handling (htonl/ntohl for network byte order) +- Variable-length encoding (only bytes needed) +- Type-aware (knows SQLite INTEGER/FLOAT/TEXT/BLOB/NULL) +- LZ4 compression applied to entire payload + +**Why custom format?** More efficient than JSON/protobuf for SQLite's type system; minimizes network bandwidth. + +### 8. Context/Handle Pattern + +Encapsulated state management with opaque pointers: + +```c +cloudsync_context // Per-database state + ├─ site_id // This database's UUID + ├─ db_version, seq // Global counters + ├─ insync flag // Transaction state + └─ cloudsync_table_context[] // Array of synced tables + ├─ table_name + ├─ algo (CLS/GOS/DWS/AWS) + ├─ column metadata + └─ prepared statements +``` + +**Benefits**: +- Multiple databases can have independent sync contexts +- Clean lifecycle: `cloudsync_context_create()` → `cloudsync_context_init()` → `cloudsync_context_free()` +- Opaque pointers (`void *`) hide implementation details +- State passed through SQLite's `sqlite3_user_data()` mechanism + +### 9. Layered Architecture + +Clear separation of concerns from bottom to top: + +``` +┌──────────────────────────────────────┐ +│ SQL Functions (Public API) │ src/sqlite/cloudsync_sqlite.c +│ - cloudsync_init() │ - Registers all SQL functions +│ - cloudsync_uuid() │ - Entry point for users +│ - cloudsync_network_sync() │ +├──────────────────────────────────────┤ +│ Network Layer (Optional) │ src/network.c/h +│ - SQLite Cloud communication │ - Uses libcurl or native APIs +│ - Retry logic, authentication │ - Can be omitted (CLOUDSYNC_OMIT_NETWORK) +├──────────────────────────────────────┤ +│ CRDT Core / Merge Logic │ src/cloudsync.c/h +│ - Payload generation/application │ - Database-agnostic +│ - Vector clock comparison │ - Core sync algorithms +│ - Conflict resolution │ +├──────────────────────────────────────┤ +│ Database Utilities │ src/dbutils.c, src/utils.c +│ - Metadata table management │ - Helper functions +│ - Trigger creation │ - UUID generation +│ - Schema validation │ - Hashing, encoding +├──────────────────────────────────────┤ +│ Database Abstraction Layer │ src/database.h +│ - Generic DB operations │ src/sqlite/database_sqlite.c +│ - Prepared statements │ src/postgresql/database_postgresql.c +│ - Memory allocation │ +├──────────────────────────────────────┤ +│ Database Engine (SQLite/PostgreSQL) │ +└──────────────────────────────────────┘ +``` + +**Key insight**: CRDT logic in `cloudsync.c` never calls SQLite directly—only uses `database.h` abstractions. This enables potential PostgreSQL support. + +### 10.

Compiling SQL on each trigger execution would make writes unacceptably slow. + +2. **Merge performance**: `cloudsync_payload_apply()` may process thousands of changes in a single sync. SQL compilation would dominate runtime. + +3. **Memory efficiency**: Prepared statements are parsed once, reused many times, and cleaned up when the context is freed. + +### Finding Prepared Statements in the Code + +- Prepared statements initialized in `cloudsync_init_table()` and stored in `cloudsync_table_context` +- Look for `sqlite3_stmt *` fields in context structures +- Lifetime: created during table init, reset after each use, finalized when context freed +- See `cloudsync.c` and `dbutils.c` for examples + +## Testing Strategy + +Tests are in `test/unit.c`.

Add test function in `test/unit.c` +2. Call from `main()` +3. Run `make test` to execute + +## Important Constraints + +### Primary Key Requirements + +Tables must use TEXT primary keys with globally unique identifiers: +- Use `cloudsync_uuid()` for UUID generation +- Integer auto-increment PKs cause conflicts across devices +- All PK columns must be `NOT NULL` + +### Column Constraints + +For CRDT merge to work correctly: +- All `NOT NULL` columns (except PKs) must have `DEFAULT` values +- This ensures column-by-column merge doesn't violate constraints + +### Triggers and Foreign Keys + +- Foreign key constraints may conflict with CRDT merge (see README for details) +- Triggers on synced tables may execute multiple times during merge +- Test thoroughly when using FKs or triggers with synced tables + +## Code Style Notes + +- Error handling via return codes (SQLITE_OK, SQLITE_ERROR, etc.) +- Memory allocation through abstraction layer (`cloudsync_memory_*` macros) +- Debug macros throughout (disabled by default): `DEBUG_FUNCTION`, `DEBUG_SQL`, etc. +- Hash tables via khash.h (header-only library) +- Compression via LZ4 for payloads +- Comments and documentation must be written in English unless explicitly asked otherwise, even if the prompt is in another language. +- Table names to augment are limited to 512 characters; size buffer allocations for SQL strings accordingly. +- Prefer static buffer allocation with `sqlite3_snprintf` for SQL string construction when practical (e.g., fixed pattern plus table name with a 1024-byte buffer) instead of dynamic `sqlite3_mprintf` to reduce allocations and cleanup. +- SQL statements: + - Parameterless SQL should live as global constants in `src//database_.c` (e.g., `const char *SQL_CREATE_SETTINGS = "CREATE TABLE ...";` in `src/sqlite/database_sqlite.c`) and be used via `extern const char *SQL_CREATE_SETTINGS;` so database backends can override as needed. + - Parameterized SQL must be provided via functions in the database layer (as with `database_count_pk`) so each backend can build statements appropriately. + - Put backend-specific SQL templates in `src//sql_.c`; add a `database_.c` helper (exposed in `database.h`) whenever placeholder rules, quoting/escaping, or catalog-driven SQL generation differ between backends. +- Preserve existing coding style and patterns (e.g., prepared statements with bind/step/reset, use `cloudsync_memory_*` macros, return SQLite error codes). Ask the user before significant structural changes or refactors. + +## PostgreSQL Database Backend Patterns + +- SPI usage: prefer `SPI_execute()` for one-shot catalog queries and `SPI_prepare` + `SPI_execute_plan` for reusable statements. +- Error handling: wrap SPI calls in `PG_TRY()/PG_CATCH()`, capture with `CopyErrorData()`, call `cloudsync_set_error(...)`, and `FlushErrorState()`; helpers should not rethrow. +- Statement lifecycle: `databasevm_prepare/step/reset/finalize` owns a `pg_stmt_t` with `stmt_mcxt`, plus `bind_mcxt` and `row_mcxt` subcontexts; reset uses `MemoryContextReset` (not free). +- Cursor strategy: use portals (`SPI_cursor_open`/`SPI_cursor_fetch`) only for cursorable plans (check `SPI_is_cursor_plan`); non-cursorable plans execute once. +- Binding: bind arrays (`values`, `nulls`, `types`) live in `bind_mcxt` and are cleared in `databasevm_clear_bindings`. +- Row access: extract values via `SPI_getbinval` with OID checks, convert to C types, and copy into cloudsync-managed buffers. +- SQL construction: prefer `snprintf` into fixed buffers, fall back to `cloudsync_memory_mprintf` for dynamic sizes. +- SPI context: helpers assume the caller has already executed `SPI_connect()`; they avoid managing SPI connection state. diff --git a/Makefile b/Makefile index 06c63e1..179a7df 100644 --- a/Makefile +++ b/Makefile @@ -2,7 +2,7 @@ # Supports compilation for Linux, macOS, Windows, Android and iOS # customize sqlite3 executable with -# make test SQLITE3=/opt/homebrew/Cellar/sqlite/3.49.1/bin/sqlite3 +# make test SQLITE3=/opt/homebrew/Cellar/sqlite/3.50.4/bin/sqlite3 SQLITE3 ?= sqlite3 # set curl version to download and build @@ -32,7 +32,7 @@ MAKEFLAGS += -j$(CPUS) # Compiler and flags CC = gcc -CFLAGS = -Wall -Wextra -Wno-unused-parameter -I$(SRC_DIR) -I$(SQLITE_DIR) -I$(CURL_DIR)/include +CFLAGS = -Wall -Wextra -Wno-unused-parameter -I$(SRC_DIR) -I$(SRC_DIR)/sqlite -I$(SRC_DIR)/postgresql -I$(SQLITE_DIR) -I$(CURL_DIR)/include T_CFLAGS = $(CFLAGS) -DSQLITE_CORE -DCLOUDSYNC_UNITTEST -DCLOUDSYNC_OMIT_NETWORK -DCLOUDSYNC_OMIT_PRINT_RESULT COVERAGE = false ifndef NATIVE_NETWORK @@ -41,10 +41,12 @@ endif # Directories SRC_DIR = src +SQLITE_IMPL_DIR = $(SRC_DIR)/sqlite +POSTGRES_IMPL_DIR = $(SRC_DIR)/postgresql DIST_DIR = dist TEST_DIR = test SQLITE_DIR = sqlite -VPATH = $(SRC_DIR):$(SQLITE_DIR):$(TEST_DIR) +VPATH = $(SRC_DIR):$(SQLITE_IMPL_DIR):$(POSTGRES_IMPL_DIR):$(SQLITE_DIR):$(TEST_DIR) BUILD_RELEASE = build/release BUILD_TEST = build/test BUILD_DIRS = $(BUILD_TEST) $(BUILD_RELEASE) @@ -59,12 +61,18 @@ ifeq ($(PLATFORM),android) OPENSSL_INSTALL_DIR = $(OPENSSL_DIR)/$(PLATFORM)/$(ARCH) endif -SRC_FILES = $(wildcard $(SRC_DIR)/*.c) +# Multi-platform source files (at src/ root) - exclude database_*.c as they're in subdirs +CORE_SRC = $(filter-out $(SRC_DIR)/database_%.c, $(wildcard $(SRC_DIR)/*.c)) +# SQLite-specific files +SQLITE_SRC = $(wildcard $(SQLITE_IMPL_DIR)/*.c) +# Combined for SQLite extension build +SRC_FILES = $(CORE_SRC) $(SQLITE_SRC) + TEST_SRC = $(wildcard $(TEST_DIR)/*.c) TEST_FILES = $(SRC_FILES) $(TEST_SRC) $(wildcard $(SQLITE_DIR)/*.c) RELEASE_OBJ = $(patsubst %.c, $(BUILD_RELEASE)/%.o, $(notdir $(SRC_FILES))) TEST_OBJ = $(patsubst %.c, $(BUILD_TEST)/%.o, $(notdir $(TEST_FILES))) -COV_FILES = $(filter-out $(SRC_DIR)/lz4.c $(SRC_DIR)/network.c, $(SRC_FILES)) +COV_FILES = $(filter-out $(SRC_DIR)/lz4.c $(SRC_DIR)/network.c $(SQLITE_IMPL_DIR)/sql_sqlite.c $(POSTGRES_IMPL_DIR)/database_postgresql.c, $(SRC_FILES)) CURL_LIB = $(CURL_DIR)/$(PLATFORM)/libcurl.a TEST_TARGET = $(patsubst %.c,$(DIST_DIR)/%$(EXE), $(notdir $(TEST_SRC))) @@ -207,14 +215,21 @@ $(BUILD_TEST)/%.o: %.c # Run code coverage (--css-file $(CUSTOM_CSS)) test: $(TARGET) $(TEST_TARGET) - $(SQLITE3) ":memory:" -cmd ".bail on" ".load ./$<" "SELECT cloudsync_version();" - set -e;

If `psql` blocks, the backend is paused at a breakpoint; continue in the debugger. + +## Option 2: Supabase Integration (cli) + +Use this when you're running `supabase start` and want CloudSync inside the local stack. +The Supabase CLI uses a bundled PostgreSQL image (for example, +`public.ecr.aws/supabase/postgres:17.6.1.071`). Build a matching image that +includes CloudSync, then tag it with the same name so the CLI reuses it. This +keeps your local Supabase stack intact (auth, realtime, storage, etc.) while +enabling the extension in the CLI-managed Postgres container. + +### Prerequisites + +- Supabase CLI installed (`supabase start` works) +- Docker running + +### Setup + +1. Initialize a Supabase project (use a separate workdir to keep generated files + out of the repo): + ```bash + mkdir -p ~/supabase-local + supabase init --workdir ~/supabase-local + ``` + +2. Start Supabase once so the CLI pulls the Postgres image: + ```bash + supabase start --workdir ~/supabase-local + ``` + +3. Build and tag a CloudSync image using the same tag as the running CLI stack: + ```bash + make postgres-supabase-build + ``` + This auto-detects the running `supabase_db` image tag and rebuilds it with + CloudSync installed. If you need to override the tag, set + `SUPABASE_CLI_IMAGE=public.ecr.aws/supabase/postgres:`. + Example: + ```bash + SUPABASE_CLI_IMAGE=public.ecr.aws/supabase/postgres:17.6.1.071 make postgres-supabase-build + ``` + +4. Restart the stack: + ```bash + supabase stop --workdir ~/supabase-local + supabase start --workdir ~/supabase-local + ``` + +### Using the CloudSync Extension + +You can load the extension automatically from a migration, or enable it +manually. + +Migration-based (notes for CLI): Supabase CLI migrations run as the `postgres` +role, which cannot create C extensions by default. Use manual enable or grant +`USAGE` on language `c` once, then migrations will work. + +If you still want a migration file, add: +```bash +~/supabase-local/supabase/migrations/00000000000000_cloudsync.sql +``` +Contents: +```sql +CREATE EXTENSION IF NOT EXISTS cloudsync; +``` + +Then either: +- run `GRANT USAGE ON LANGUAGE c TO postgres;` once as `supabase_admin`, or +- skip the migration and enable the extension manually after `supabase db reset`. + +Manual enable (no reset required): + +Connect as the Supabase superuser (C extensions require superuser or language +privileges), then enable the extension: + +```bash +psql postgresql://supabase_admin:postgres@127.0.0.1:54322/postgres +``` + +```sql +CREATE EXTENSION cloudsync; +SELECT cloudsync_version(); +``` + +If you want to use the `postgres` role instead: + +```sql +GRANT USAGE ON LANGUAGE c TO postgres; +``` + +### Rebuilding After Changes + +If you modify the CloudSync source code, rebuild the CLI image and restart: + +```bash +make postgres-supabase-rebuild SUPABASE_WORKDIR=~/supabase-local +``` + +### Supabase Realtime Migration Error (app_schema_version) + +If Supabase Realtime fails to start with: + +``` +ERROR 42P01 (undefined_table) relation "app_schema_version" does not exist +``` + +it's caused by CloudSync's `app_schema_change` event trigger firing during +migrations while Realtime uses a restricted `search_path`. Fix it by +fully qualifying the table in the trigger function: + +```sql +CREATE TABLE IF NOT EXISTS public.app_schema_version ( + version BIGINT GENERATED ALWAYS AS IDENTITY PRIMARY KEY +); + +CREATE OR REPLACE FUNCTION bump_app_schema_version() +RETURNS event_trigger AS $$ +BEGIN + INSERT INTO public.app_schema_version DEFAULT VALUES; +END; +$$ LANGUAGE plpgsql; + +DROP EVENT TRIGGER IF EXISTS app_schema_change; +CREATE EVENT TRIGGER app_schema_change +ON ddl_command_end +EXECUTE FUNCTION bump_app_schema_version(); +``` + +## Development Workflow + +### 1.

In practice, it means a SPI tuptable (or a relation opened internally by SPI when executing a query) wasn’t released before the outer SQL statement completed. PostgreSQL 17 is stricter about reporting this, so the same issue might have been silent in earlier versions. + +We isolated the warning to the `cloudsync_payload_apply` path when it inserted into the `cloudsync_changes` view and triggered `cloudsync_changes_insert_trigger`. The warnings did **not** occur for direct, manual `INSERT INTO cloudsync_changes ...` statements issued in psql. + +## Why it only happened in the payload-apply path +The key difference was **nested SPI usage** and **statement lifetime**: + +1. **`cloudsync_payload_apply` loops many changes and uses SPI internally** + - `cloudsync_payload_apply` is a C function that processes a payload by decoding multiple changes and applying them in a loop. + - For each change, it executed an `INSERT INTO cloudsync_changes (...)` (via `SQL_CHANGES_INSERT_ROW`), which fires the INSTEAD OF trigger (`cloudsync_changes_insert_trigger`). + +2. **The trigger itself executed SPI queries** + - The trigger function uses SPI to read and write metadata tables. + - This creates *nested* SPI usage within a call stack that is already inside a SPI-driven C function. + +3. **Nested SPI + `INSERT INTO view` has different resource lifetime than a plain insert** + - With a manual psql statement, the SPI usage occurs only once, in a clean top-level context. The statement finishes, SPI cleanup happens, and any tuptable resources are released. + - In the payload apply path, SPI queries happen inside the trigger, inside another SPI-driven C function, inside a loop. If any intermediate SPI tuptable or relation is not freed, it can “leak” out of the trigger scope and be reported when the outer statement completes. + - That’s why the warning appears specifically when the trigger is executed as part of `cloudsync_payload_apply` but not for direct inserts from psql. + +4. **PostgreSQL 17 reports this more aggressively** + - Earlier versions often tolerated missing `SPI_freetuptable()` calls without warning. PG17 emits the warning when the statement finishes and resources are still registered as open. + +## Why direct INSERTs from psql didn’t warn +The smoke test included a manual `INSERT INTO cloudsync_changes ...`, and it never produced the warning. That statement: + +- Runs as a single SQL statement initiated by the client. +- Executes the trigger in a clean SPI call stack with no nested SPI calls. +- Completes quickly, and the SPI context is unwound immediately, which can mask missing frees. + +In contrast, the payload-apply path: + +- Opens SPI state for the duration of the payload apply loop. +- Executes many trigger invocations before returning. +- Accumulates any unfreed resources over several calls. + +So the leak only becomes visible in the payload-apply loop. + +## Fix that removed the warning +We introduced a new SQL function that bypasses the trigger and does the work directly: + +- Added `cloudsync_changes_apply(...)` and rewired `SQL_CHANGES_INSERT_ROW` to call it via: + ```sql + SELECT cloudsync_changes_apply(...) + ``` +- The apply function executes the same logic but without inserting into the view and firing the INSTEAD OF trigger. +- This removes the nested SPI + trigger path for the payload apply loop. + +Additionally, we tightened SPI cleanup in multiple functions by ensuring `SPI_freetuptable(SPI_tuptable)` is called after `SPI_execute`/`SPI_execute_plan` calls where needed. + +## Takeaway +The warning was not tied to the `cloudsync_changes` view itself, but to **nested SPI contexts and missing SPI cleanup** during payload apply. It was only visible when: + +- the apply loop executed many insert-trigger calls, and +- the server (PG17) reported unclosed relation resources at statement end. + +By switching to `cloudsync_changes_apply(...)` and tightening SPI tuptable cleanup, we removed the warning from the payload-apply path while leaving manual insert behavior unchanged. + +## Next TODO +- Add SPI instrumentation (DEBUG1 logs before/after SPI_execute* and after SPI_freetuptable/SPI_finish) along the payload-apply → view-insert → trigger path, then rerun the instrumented smoke test to pinpoint exactly where the warning is emitted. +- Note: We inspected the payload-apply → INSERT INTO cloudsync_changes → trigger call chain and did not find any missing SPI_freetuptable() or SPI_finish() calls in that path. diff --git a/plans/PG_CLOUDSYNC_CHANGES_COL_VALUE_BYTEA.md b/plans/PG_CLOUDSYNC_CHANGES_COL_VALUE_BYTEA.md new file mode 100644 index 0000000..62f6b1c --- /dev/null +++ b/plans/PG_CLOUDSYNC_CHANGES_COL_VALUE_BYTEA.md @@ -0,0 +1,104 @@ +# Plan: PG cloudsync_changes col_value as encoded bytea + +Requirements (must hold): +- Keep payload format and pk encode/decode logic unchanged. +- Payloads must be interchangeable between SQLite and PostgreSQL peers. +- PostgreSQL `cloudsync_changes.col_value` should carry the already-encoded bytea (type-tagged cloudsync bytes) exactly like SQLite. +- The PostgreSQL layer must pass that bytea through without decoding; decoding happens only when applying to the base table value type. +- Keeping `col_value` as `text` (and casting in SQL) is not acceptable because `pk_encode` would treat it as `DBTYPE_TEXT`, losing original type info (numbers/blobs/null semantics) and producing payloads that are not portable to SQLite peers. + +Goals and tradeoffs for the cached helper approach: +- Goal: preserve SQLite-compatible payloads by encoding `col_value` with the same pk wire format before it reaches the SRF/view layer. +- Goal: avoid per-row plan preparation by caching a `SPIPlanPtr` keyed by `(relid, attnum)` for column lookup. +- Tradeoff: still does per-row SPI execution (can’t avoid row fetch); cost is mitigated by cached plans. +- Tradeoff: uses text parameters and type casts in the cached plan, which is slower than binary binding but simpler and type-agnostic. + +Goal: make PostgreSQL `cloudsync_changes.col_value` carry the same type-tagged, cloudsync-encoded bytes as SQLite so `cloudsync_payload_encode` can consume it without dynamic type inference. + +## 1) Inventory and impact analysis +- Schema/SQL definition assumes text: + - `src/postgresql/cloudsync--1.0.sql` declares `cloudsync_changes_srf` with `col_value text`, and the `cloudsync_changes` view is a straight `SELECT *` from the SRF. +- SRF query construction assumes text and uses text filtering: + - `src/postgresql/cloudsync_postgresql.c` `build_union_sql()` builds `COALESCE((SELECT to_jsonb(b)->>t1.col_name ...), '%s') AS col_value` and filters with `s.col_value IS DISTINCT FROM '%s'`. + - The empty-set fallback uses `NULL::text AS col_value`. +- INSERT path expects text and re-casts to the target type: + - `src/postgresql/cloudsync_postgresql.c` `cloudsync_changes_insert_trg` reads `col_value` as text (`text_to_cstring`), looks up the real column type, and casts via `SELECT $1::type` before building a `pgvalue_t`. +- SQL constants and core insert path target `cloudsync_changes`: + - `src/postgresql/sql_postgresql.c` `SQL_CHANGES_INSERT_ROW` inserts into `cloudsync_changes(tbl, pk, col_name, col_value, ...)`. + - `src/cloudsync.c` uses `SQL_CHANGES_INSERT_ROW` via the database abstraction, so any type change affects core insert/merge flows. +- Payload encode aggregation currently treats `col_value` as whatever type the query returns: + - `src/postgresql/cloudsync_postgresql.c` `cloudsync_payload_encode_transfn` wraps variadic args with `pgvalues_from_args`; a `bytea` `col_value` would flow through as `bytea` without special handling, but any text assumptions in callers must be updated. +- Tests/docs: + - All `cloudsync_changes` tests are in SQLite (`test/unit.c`); there are no PG-specific tests or docs referencing `col_value` type. + +## 2) Define encoding contract for col_value (PG) +- Encoding contract (align with SQLite): + - `col_value` is a `bytea` containing the pk-encoded value bytes (type tag + payload), same as SQLite `cloudsync_changes`. + - `NULL` uses the same pk-encode NULL marker; no PG-specific sentinel encoding. + - RLS/tombstone filtering should be done before encoding, or by comparing encoded bytes with the known encoded sentinel bytes. +- PG-side encoding strategy: + - Add a C helper that takes a `Datum` + type metadata and returns encoded bytes using existing `pk_encode` path (`dbvalue_t` wrapper + `pk_encode`). + - Avoid JSON/text conversions; the SRF should fetch the base-table `Datum` and encode directly. + - Compute `col_value` for a given row using: + - PK decode predicate to locate the row. + - Column `Datum` from SPI tuple (or a helper function returning `Datum`). +- PG payload encode path: + - Treat `col_value` as already-encoded bytes; pass through without decoding. + - Ensure `pgvalues_from_args` preserves `bytea` and `pk_encode` does not re-encode it (it should encode the container row, not the inner value bytes). + - Avoid any path that casts `col_value` to text in `cloudsync_changes_insert_trg`. + +Concrete implementation steps for step 2: +- Add a PG helper to encode a single `Datum` into cloudsync bytes: + - Implement `static bytea *pg_cloudsync_encode_value(Datum val, Oid typeid, int32 typmod, Oid collation, bool isnull)` in `src/postgresql/cloudsync_postgresql.c` (or a new `pg_encode.c`). + - Wrap the `Datum` into a `pgvalue_t` via `pgvalue_create`, then call `pk_encode` with `argc=1` and `is_prikey=false`. + - Allocate a `bytea` with `VARHDRSZ + encoded_len` and copy the encoded bytes; return the `bytea`. + - Ensure text/bytea are detoasted before encoding (via `pgvalue_ensure_detoast`). +- Add a PG helper to encode a column from a base table row: + - Implement `static bytea *pg_cloudsync_encode_col_from_tuple(HeapTuple tup, TupleDesc td, int attnum)` that: + - Extracts `Datum` and `isnull` with `SPI_getbinval`. + - Uses `TupleDescAttr(td, attnum-1)` to capture type/typmod/collation. + - Calls `pg_cloudsync_encode_value(...)` and returns the encoded `bytea`. +- Update `build_union_sql()` logic to select encoded bytes instead of text: + - Replace the `to_jsonb(...)->>t1.col_name` subselect with a SQL-callable C function: + - New SQL function: `cloudsync_col_value_encoded(table_name text, col_name text, pk bytea) RETURNS bytea`. + - In C, implement `cloudsync_col_value_encoded` to: + - Look up table OID and PK columns. + - Decode `pk` with `cloudsync_pk_decode` to build a WHERE clause. + - Fetch the row via SPI, extract the target column `Datum`, encode it via `pg_cloudsync_encode_value`, and return `bytea`. + - This avoids dynamic SQL in `build_union_sql()` and keeps encoding centralized. +- Define behavior for restricted/tombstone rows: + - If the row is not visible or the column cannot be read, return an encoded version of `CLOUDSYNC_RLS_RESTRICTED_VALUE` (text encoded with pk_encode). + - If `col_name` is tombstone sentinel, return encoded NULL (match SQLite behavior). +- Ensure payload encode path expects bytea: + - Confirm `cloudsync_payload_encode_transfn` receives `bytea` for `col_value` from `cloudsync_changes`. + - `pgvalues_from_args` should keep `bytea` as `DBTYPE_BLOB` so `pk_encode` wraps it as a blob field. + +## 3) Update cloudsync_changes schema and SRF/view +- Update `src/postgresql/cloudsync--1.0.sql`: + - `cloudsync_changes_srf` return type: change `col_value text` -> `col_value bytea`. + - Regenerate or update extension SQL if necessary for versioning. +- Update `build_union_sql()` in `src/postgresql/cloudsync_postgresql.c`: + - Replace the current `to_jsonb(...)`/`text` approach with encoded `bytea`. + - Use the PK decode predicate to fetch the base row and feed the value to the encoder. + - Keep the RLS/tombstone filtering logic consistent with SQLite semantics. +- Update any SQL constants in `src/postgresql/sql_postgresql.c` that target `cloudsync_changes` to treat `col_value` as `bytea`. + +## 4) Update INSERT trigger and payload encode path +- In `cloudsync_changes_insert_trg`: + - Accept `col_value` as `bytea` (already encoded). + - Avoid casting to text or re-encoding. + - Ensure typed `dbvalue_t` construction uses the encoded bytes (or passes through unchanged). +- In `cloudsync_payload_encode`/aggregate path: + - If it currently expects a text value, adjust to consume encoded `bytea`. + - Confirm the encoded bytes are fed to `pk_encode` (or the payload writer) exactly once. + +## 5) Tests and verification +- Add a PG unit or SQL smoke test that: + - Inserts rows with multiple types (text, integer, float, bytea, null). + - Queries `cloudsync_changes` and verifies `col_value` bytea can round-trip decode to the original value/type. + - Compares payload bytes against SQLite for identical input (if a cross-check harness exists). +- If no PG test harness exists, add a minimal SQL script in `test/` with manual steps and expected outcomes. + +## 6) Rollout notes and documentation +- Update `POSTGRESQL.md` or relevant docs to mention `col_value` is `bytea` and already cloudsync-encoded. +- Note any compatibility constraints for consumers expecting `text`. diff --git a/plans/POSTGRESQL_IMPLEMENTATION.md b/plans/POSTGRESQL_IMPLEMENTATION.md new file mode 100644 index 0000000..becbcd5 --- /dev/null +++ b/plans/POSTGRESQL_IMPLEMENTATION.md @@ -0,0 +1,583 @@ +# PostgreSQL Implementation Plan + +## Goal +Refactor the codebase to separate multi-platform code from database-specific implementations, preparing for PostgreSQL extension development. + +## Directory Structure (Target) + +``` +src/ +├── cloudsync.c/h # Multi-platform CRDT core +├── pk.c/h # Multi-platform payload encoding +├── network.c/h # Multi-platform network layer +├── dbutils.c/h # Multi-platform database utilities +├── utils.c/h # Multi-platform utilities +├── lz4.c/h # Multi-platform compression +├── database.h # Database abstraction API +│ +├── sqlite/ # SQLite-specific implementations +│ ├── database_sqlite.c +│ ├── cloudsync_sqlite.c +│ ├── cloudsync_sqlite.h +│ ├── cloudsync_changes_sqlite.c/h # (renamed from vtab.c/h) +│ └── sql_sqlite.c # SQLite SQL constants +│ +└── postgresql/ # PostgreSQL-specific implementations + ├── database_postgresql.c # Database abstraction (✅ implemented) + ├── cloudsync_postgresql.c # Extension functions (✅ Phase 8) + └── cloudsync--1.0.sql # SQL installation script (✅ Phase 8) +``` + +## Implementation Steps + +### Phase 1: Directory Structure ✅ +- [x] Create src/sqlite/ directory +- [x] Create src/postgresql/ directory +- [x] Create docker/postgresql/ directory +- [x] Create docker/supabase/ directory +- [x] Create test/sqlite/ directory +- [x] Create test/postgresql/ directory + +### Phase 2: Move and Rename Files ✅ +- [x] Move src/database_sqlite.c → src/sqlite/ +- [x] Move src/cloudsync_sqlite.c → src/sqlite/ +- [x] Move src/cloudsync_sqlite.h → src/sqlite/ +- [x] Rename and move src/vtab.c → src/sqlite/cloudsync_changes_sqlite.c +- [x] Rename and move src/vtab.h → src/sqlite/cloudsync_changes_sqlite.h +- [x] Move src/database_postgresql.c → src/postgresql/ + +### Phase 3: Update Include Paths ✅ +- [x] Update includes in src/sqlite/database_sqlite.c +- [x] Update includes in src/sqlite/cloudsync_sqlite.c +- [x] Update includes in src/sqlite/cloudsync_changes_sqlite.c +- [x] Update includes in src/sqlite/cloudsync_sqlite.h +- [x] Update includes in src/postgresql/database_postgresql.c +- [x] Update includes in multi-platform files that reference vtab.h + +### Phase 4: Update Makefile ✅ +- [x] Update VPATH to include src/sqlite and src/postgresql +- [x] Update CFLAGS to include new directories +- [x] Update SRC_FILES to include files from subdirectories +- [x] Ensure test targets still work + +### Phase 5: Verification ✅ +- [x] Run `make clean` +- [x] Run `make` -

PostgreSQL-specific variadic argument handling +- ⚠️ 3 aggregate functions need completion (update transfn/finalfn, payload_encode transfn) +- ⏳ Needs compilation testing with PostgreSQL headers +- ⏳ Needs integration testing with cloudsync core + +## SQL Parity Review (PostgreSQL vs SQLite) + +Findings comparing `src/postgresql/sql_postgresql.c` to `src/sqlite/sql_sqlite.c`: +- Missing full DB version query composition: SQLite builds a UNION of all `*_cloudsync` tables plus `pre_alter_dbversion`; PostgreSQL has a two-step builder but no `pre_alter_dbversion` or execution glue. +- `SQL_DATA_VERSION`/`SQL_SCHEMA_VERSION` are TODO placeholders (`SELECT 1`), not equivalents to SQLite pragmas. +- `SQL_SITEID_GETSET_ROWID_BY_SITEID` returns `ctid` and lacks the upsert/rowid semantics of SQLite’s insert-or-update/RETURNING rowid. +- Row selection/build helpers (`*_BY_ROWID`, `*_BY_PK`) are reduced placeholders using `ctid` or simple string_agg; they do not mirror SQLite’s dynamic SQL with ordered PK clauses and column lists from `pragma_table_info`. +- Write helpers (`INSERT_ROWID_IGNORE`, `UPSERT_ROWID_AND_COL_BY_ROWID`, PK insert/upsert formats) diverge: SQLite uses `rowid` and conflict clauses; PostgreSQL variants use `%s` placeholders without full PK clause/param construction. +- Cloudsync metadata upserts differ: `SQL_CLOUDSYNC_UPSERT_COL_INIT_OR_BUMP_VERSION`/`_RAW_COLVERSION` use `EXCLUDED` logic not matching SQLite’s increment rules; PK tombstone/cleanup helpers are partial. +- Many format strings lack quoting/identifier escaping parity (`%w` behavior) and expect external code to supply WHERE clauses, making them incomplete compared to SQLite’s self-contained templates. + +TODOs to fix `sql_postgresql.c`: +- Recreate DB version query including `pre_alter_dbversion` union and execution wrapper. +- Implement PostgreSQL equivalents for data_version/schema_version. +- Align site_id getters/setters to return stable identifiers (no `ctid`) and mirror SQLite upsert-return semantics. +- Port the dynamic SQL builders for select/delete/insert/upsert by PK/non-PK to generate complete statements (including ordered PK clauses and binds), respecting identifier quoting. +- Align cloudsync metadata updates/upserts/tombstoning to SQLite logic (version bump rules, ON CONFLICT behavior, seq/db_version handling). +- Ensure all format strings include proper identifier quoting and do not rely on external WHERE fragments unless explicitly designed that way. + +**Next Steps:** +- Implement PostgreSQL anyarray handling for variadic functions (pk_encode, pk_decode, insert) +- Complete aggregate function implementations (update, payload_encode) +- Add PostgreSQL-specific Makefile targets +- Build and test extension in Docker container + +### [2025-12-19] Implemented cloudsync_insert ✅ + +Completed the `cloudsync_insert` function using the new `pgvalue_t` infrastructure: + +**Implementation Details:** + +1. **Signature**: `cloudsync_insert(table_name text, VARIADIC pk_values anyarray)` + - Uses PostgreSQL's VARIADIC to accept variable number of PK values + - Converts anyarray to `pgvalue_t **` using `pgvalues_from_array()` + +2. **Key Features**: + - Validates table exists and PK count matches expected + - Encodes PK values using `pk_encode_prikey()` with stack buffer (1024 bytes) + - Handles sentinel records for PK-only tables + - Marks all non-PK columns as inserted in metadata + - Proper memory management: frees `pgvalue_t` wrappers after use + +3. **Error Handling**: + - Comprehensive cleanup in both success and error paths + - Uses `goto cleanup` pattern for centralized resource management + - Wraps in `PG_TRY/CATCH` for PostgreSQL exception safety + - Cleans up resources before re-throwing exceptions + +4. **Follows SQLite Logic**: + - Matches `dbsync_insert` behavior from `src/sqlite/cloudsync_sqlite.c` + - Same sequence: encode PK → get next version → check existence → mark metadata + - Handles both new inserts and updates to previously deleted rows + +**Status**: +- ✅ `cloudsync_insert` fully implemented +- ✅ `cloudsync_pk_encode` already implemented (was done in previous work) +- ✅ `cloudsync_payload_encode_transfn` already implemented (uses pgvalues_from_args) +- ⚠️ `cloudsync_pk_decode` still needs callback implementation +- ⚠️ `cloudsync_update_*` aggregate functions still need implementation + +**Function Count Update**: 21/27 functions (78%) now fully implemented + +### [2025-12-19] PostgreSQL Makefile Targets Complete ✅ + +Implemented comprehensive Makefile infrastructure for PostgreSQL extension development: + +**Files Created/Modified:** + +1. **`docker/Makefile.postgresql`** - New PostgreSQL-specific Makefile with all build targets: + - Build targets: `postgres-check`, `postgres-build`, `postgres-install`, `postgres-clean`, `postgres-test` + - Docker targets: `postgres-docker-build`, `postgres-docker-run`, `postgres-docker-stop`, `postgres-docker-rebuild`, `postgres-docker-shell` + - Development targets: `postgres-dev-rebuild` (fast rebuild in running container) + - Help target: `postgres-help` + +2. **Root `Makefile`** - Updated to include PostgreSQL targets: + - Added `include docker/Makefile.postgresql` statement + - Added PostgreSQL help reference to main help output + - All targets accessible from root: `make postgres-*` + +3. **`docker/postgresql/Dockerfile`** - Updated to use new Makefile targets: + - Uses `make postgres-build` and `make postgres-install` + - Verifies installation with file checks + - Adds version labels + - Keeps source mounted for development + +4. **`docker/postgresql/docker-compose.yml`** - Enhanced volume mounts: + - Mounts `docker/` directory for Makefile.postgresql access + - Enables quick rebuilds without image rebuild + +5. **`docker/README.md`** - Updated documentation: + - Simplified quick start using new Makefile targets + - Updated development workflow section + - Added fast rebuild instructions + +6. **`POSTGRESQL.md`** - New comprehensive quick reference guide: + - All Makefile targets documented + - Development workflow examples + - Extension function reference + - Connection details and troubleshooting + +**Key Features:** + +- **Single Entry Point**: All PostgreSQL targets accessible via `make postgres-*` from root +- **Pre-built Image**: `make postgres-docker-build` creates image with extension pre-installed +- **Fast Development**: `make postgres-dev-rebuild` rebuilds extension in <5 seconds without restarting container +- **Clean Separation**: PostgreSQL logic isolated in `docker/Makefile.postgresql`, included by root Makefile +- **Docker-First**: Optimized for containerized development with source mounting + +**Usage Examples:** + +```bash +# Build Docker image with CloudSync extension +make postgres-docker-build + +# Start PostgreSQL container +make postgres-docker-run + +# Test extension +docker exec -it cloudsync-postgres psql -U postgres -d cloudsync_test \ + -c "CREATE EXTENSION cloudsync; SELECT cloudsync_version();" + +# Make code changes,

(README + POSTGRESQL.md) +- ⏳ Ready for first build and compilation test +- ⏳ Needs actual PostgreSQL compilation verification + +**Next Steps:** +- Test actual compilation: `make postgres-docker-build` +- Fix any compilation errors +- Test extension loading: `CREATE EXTENSION cloudsync` +- Complete remaining aggregate functions + +### [2025-12-20] PostgreSQL Trigger + SPI Cleanup Work ✅ + +**Trigger functions implemented in `src/postgresql/database_postgresql.c`:** +- `database_create_insert_trigger` implemented with per-table PL/pgSQL function and trigger. +- `database_create_update_trigger_gos`/`database_create_delete_trigger_gos` implemented (BEFORE triggers, raise on update/delete when enabled). +- `database_create_update_trigger` implemented with VALUES list + `cloudsync_update` aggregate call. +- `database_create_delete_trigger` implemented to call `cloudsync_delete`. +- `database_create_triggers` wired to create insert/update/delete triggers based on algo. +- `database_delete_triggers` updated to drop insert/update/delete triggers and their functions. + +**PostgreSQL SQL registration updates:** +- Added `cloudsync_delete` to `src/postgresql/cloudsync--1.0.sql`. + +**Internal function updates:** +- Implemented `cloudsync_delete` C function (mirrors SQLite delete path). +- `cloudsync_insert`/`cloudsync_delete` now lazily load table context when missing. +- Refactored `cloudsync_insert`/`cloudsync_delete` to use `PG_ENSURE_ERROR_CLEANUP` and shared cleanup helper. + +**SPI execution fixes:** +- `databasevm_step` now uses `SPI_is_cursor_plan` before opening a portal to avoid “cannot open INSERT query as cursor”. +- Persistent statements now allocate their memory contexts under `TopMemoryContext`. + +**Error formatting:** +- `cloudsync_set_error` now avoids `snprintf` aliasing when `database_errmsg` points at `data->errmsg`. + +**Smoke test updates:** +- `docker/postgresql/smoke_test.sql` now validates insert/delete metadata, tombstones, and site_id fields. +- Test output uses `\echo` markers for each check. + +**Documentation updates:** +- Added PostgreSQL SPI patterns to `AGENTS.md`. +- Updated

In the SQLite shell: - ```sql - .load ./dist/cloudsync -- adjust suffix for your OS - CREATE TABLE notes (id TEXT PRIMARY KEY NOT NULL, body TEXT DEFAULT ''); - SELECT cloudsync_init('notes', 'CLS'); - INSERT INTO notes VALUES (cloudsync_uuid(), 'hello'); - SELECT * FROM cloudsync_changes WHERE tbl='notes'; -- view pending changes - ``` - -## Build Commands - -### Building the Extension - -```bash -# Build for current platform (auto-detected) -make - -# Build with code coverage -make test COVERAGE=true - -# Build for specific platforms -make PLATFORM=macos -make PLATFORM=linux -make PLATFORM=windows -make PLATFORM=android ARCH=arm64-v8a ANDROID_NDK=/path/to/ndk -make PLATFORM=ios -make PLATFORM=ios-sim - -# Build Apple XCFramework -make xcframework - -# Build Android AAR package -make aar -``` - -### Testing - -```bash -# Run all tests (builds extension + unit tests, runs in SQLite) -make test - -# Run only unit tests -make unittest - -# Run tests with coverage report (generates coverage/ directory with HTML report) -make test COVERAGE=true - -# Run with custom SQLite3 binary -make test SQLITE3=/path/to/sqlite3 -``` - -**macOS Testing Note:** If the default `/usr/bin/sqlite3` doesn't support loading extensions, set the SQLITE3 variable when running tests (Adjust the version path if using a specific version like /opt/homebrew/Cellar/sqlite/3.50.4/bin/sqlite3: -``` -make test SQLITE3=/opt/homebrew/bin/sqlite3 -make unittest SQLITE3=/opt/homebrew/bin/sqlite3 -``` - -### Build System - -The Makefile supports cross-platform compilation: -- Auto-detects host platform (Linux, macOS, Windows) -- Uses parallel builds (`-j` based on CPU cores) -- Handles platform-specific compilers, flags, and dependencies -- Downloads and builds curl statically with minimal feature set for network layer -- For Android: requires ANDROID_NDK environment variable and ARCH parameter - -### Cleaning - -```bash -# Remove all build artifacts -make clean -``` - -## Directory Structure - -The codebase is organized to separate multi-platform (database-agnostic) code from database-specific implementations: - -``` -src/ -├── cloudsync.c/h # Multi-platform CRDT core -├── pk.c/h # Multi-platform payload encoding -├── network.c/h # Multi-platform network layer -├── dbutils.c/h # Multi-platform database utilities -├── utils.c/h # Multi-platform utilities (UUID, hashing, etc.) -├── lz4.c/h # Multi-platform compression -├── database.h # Database abstraction API -│ -├── sqlite/ # SQLite-specific implementations -│ ├── database_sqlite.c # Implements database.h for SQLite -│ ├── cloudsync_sqlite.c # Extension entry point -│ ├── cloudsync_sqlite.h -│ └── cloudsync_changes_sqlite.c/h # Virtual table implementation -│ -└── postgresql/ # PostgreSQL-specific implementations - ├── database_postgresql.c # Implements database.h for PostgreSQL - ├── cloudsync_pg.c # Extension entry point - └── cloudsync_pg.h -``` - -**Key principles:** -- Files at `src/` root are multi-platform and work with any database via `database.h` -- Files in `src/sqlite/` and `src/postgresql/` contain database-specific code -- All database interaction goes through the abstraction layer defined in `database.h` - -## Core Architecture - -### Database Abstraction Layer - -The codebase uses a database abstraction layer (`database.h`) that wraps database-specific APIs. Database-specific implementations are organized in subdirectories: `src/sqlite/database_sqlite.c` for SQLite, `src/postgresql/database_postgresql.c` for PostgreSQL. All database interactions go through this abstraction layer using: -- `cloudsync_context` - opaque per-database context shared across layers -- `dbvm_t` - opaque prepared statement/virtual machine handle -- `dbvalue_t` - opaque database value handle - -The abstraction exposes: -- Result/status codes (`DBRES`), data types (`DBTYPE`), and flags (`DBFLAG`). -- Core query helpers (`database_exec`, `database_select_*`, `database_write`). -- Schema/metadata helpers (`database_table_exists`, `database_trigger_exists`, `database_count_*`, `database_pk_names`). -- Transaction helpers (`database_begin_savepoint`, `database_commit_savepoint`, `database_rollback_savepoint`, `database_in_transaction`). -- VM lifecycle (`databasevm_prepare/step/reset/finalize/clear_bindings`) plus bind/value/column accessors. -- Backend memory helpers (`dbmem_*`) and SQL builder helpers (`sql_build_*`). - -### CRDT Implementation - -The extension implements four CRDT algorithms for different use cases: - -1. **CLS (Causal-Length Set)** - Default algorithm, balances add/delete operations -2. **GOS (Grow-Only Set)** - Additions only, deletions create tombstones -3. **DWS (Delete-Wins Set)** - Deletions take precedence over additions -4. **AWS (Add-Wins Set)** - Additions take precedence over deletions - -Algorithm selection is per-table via `cloudsync_init(table_name, algo)`. - -### Key Components - -#### Core Sync Engine (`cloudsync.c/h`) - -The main synchronization logic and public API. Key structures: -- `cloudsync_context` - Per-database sync context (site ID, version, sequence counters) -- `cloudsync_table_context` - Per-table sync metadata (algorithm, columns, primary keys) - -Critical functions: -- `cloudsync_init_table()` - Initializes table for sync, creates metadata tables and triggers -- `cloudsync_payload_save()` - Exports changes as binary payload -- `cloudsync_payload_apply()` - Applies incoming changes with CRDT merge logic -- `cloudsync_commit_hook()` / `cloudsync_rollback_hook()` - Transaction hooks for change tracking - -#### Virtual Table (`src/sqlite/cloudsync_changes_sqlite.c`) - -Implements `cloudsync_changes` virtual table (SQLite-specific) that provides a SQL interface to view pending changes: -```sql -SELECT * FROM cloudsync_changes WHERE tbl='my_table'; -``` - -#### Payload Encoding (`pk.c`) - -Efficient binary serialization of database changes: -- Platform-independent (handles endianness with htonl/ntohl) -- Encodes type information + variable-length data -- Minimizes payload size for network transmission -- Supports all SQLite types (integer, float, text, blob, null) - -#### Network Layer (`network.c/h`) - -Built-in synchronization with SQLite Cloud: -- Uses libcurl for HTTPS communication -- Handles authentication (API keys and JWT tokens) -- Implements retry logic and state reconciliation -- Functions: `cloudsync_network_init()`, `cloudsync_network_sync()`, etc. - -#### Database Utilities (`dbutils.c/h`) - -Helper functions for: -- Creating/managing sync metadata tables (`cloudsync_settings`, `cloudsync_table_settings`, etc.) -- Schema validation and sanity checks -- Trigger management for change tracking -- Settings persistence (sync versions, sequences, algorithms) - -#### UUID Generation (`utils.c`) - -Implements UUIDv7 generation optimized for distributed systems: -- Timestamp-based with monotonic ordering -- Globally unique across devices -- Available via `cloudsync_uuid()` SQL function - -### Metadata Tables - -The extension creates internal tables to track sync state: - -- `cloudsync_settings` - Global sync configuration and state -- `cloudsync_table_settings` - Per-table sync configuration -- `cloudsync_site_id` - Unique site identifier for this database -- `cloudsync_schema_versions` - Schema version tracking -- `{table}_cloudsync` - Per-table CRDT metadata (logical clock, site IDs) - -### Change Tracking - -The extension uses SQLite triggers to automatically track all changes: -- INSERT triggers mark new rows for synchronization -- UPDATE triggers record which columns changed and their versions -- DELETE triggers create tombstone records (for most CRDT algorithms) -- Triggers are created/managed by `cloudsync_init()` based on the chosen algorithm - -### Merge Algorithm - -When applying remote changes via `cloudsync_payload_apply()`: - -1. Changes are deserialized from binary payload -2. For each change, CRDT algorithm determines conflict resolution: - - Compares vector clocks (db_version, sequence, site_id) - - Column-by-column merge based on causal ordering - - Handles concurrent updates deterministically -3. Local database updated with winning values -4. Metadata tables updated with merge results - -## Architecture Patterns - -Understanding the architectural patterns helps when modifying or extending the codebase. - -### 1. SQLite Extension Pattern - -The entire system is built as a **loadable SQLite extension**: -- Single entry point: `sqlite3_cloudsync_init()` in `src/sqlite/cloudsync_sqlite.c` -- Registers custom SQL functions during initialization -- Extends SQLite without modifying its core -- Loaded dynamically: `.load ./cloudsync` or `SELECT load_extension('./cloudsync')` - -**Key benefit**: Users add sync to existing SQLite apps by loading the extension and calling setup functions—no application rewrite needed. - -### 2. Shadow Metadata Tables Pattern - -For each synced table (e.g., `users`), the extension creates parallel metadata tables: - -``` -users (user's actual data - unchanged) -users_cloudsync (CRDT metadata: versions, site_ids, per-column logical clock) -``` - -**Benefits**: -- Zero schema pollution—user tables remain unchanged -- Efficient queries like "what changed since version X" -- Metadata separate from application data -- Users can drop sync by removing metadata tables - -### 3. Vector Clock CRDT Pattern - -Each column value carries a **vector clock** for causal ordering: - -```c -// Stored in {table}_cloudsync for each column: -- col_version: Lamport clock for a specific column, used to resolve merge conflicts when syncing databases that have taken independent writes. The primary purpose of col_version is to determine which value "wins" when two different peers update the same column of the same row offline and then merge their changes. The value with the higher col_version is selected as the most recent/authoritative one. -- db_version: Lamport clock for the entire database. This value is incremented with every transaction. -- site_id: UUID identifying which device made the change -- seq: sequence number for ordering changes within same db_version -``` - -**Merge algorithm** (column-by-column): -1. Compare vector clocks between local and remote values -2. Higher version wins (causally later) -3. Same version → use site_id as deterministic tiebreaker -4. No data loss, no manual conflict resolution - -**Why column-level?** Allows merging concurrent updates to different columns of the same row (e.g., User A updates email, User B updates phone—both changes preserved). - -### 4. Trigger-Based Change Tracking Pattern - -All changes captured **declaratively** using SQLite triggers: - -```sql --- Auto-generated for each synced table -CREATE TRIGGER users_insert_trigger AFTER INSERT ON users -BEGIN - INSERT INTO users_cloudsync (...); -- Record CRDT metadata -END; -``` - -**User experience**: -```sql --- User just does normal SQL: -INSERT INTO users (id, name) VALUES (cloudsync_uuid(), 'Alice'); -UPDATE users SET email = 'alice@example.com' WHERE id = '...'; -DELETE FROM users WHERE id = '...'; - --- Triggers automatically capture metadata—no API calls needed -``` - -**Implementation**: Triggers created/destroyed by `cloudsync_init()` / `cloudsync_cleanup()` in `dbutils.c`. - -### 5. Transaction Hook Pattern - -Integrates with SQLite transaction lifecycle via callbacks: - -```c -// Registered during extension initialization: -sqlite3_commit_hook(db, cloudsync_commit_hook, ctx); -sqlite3_rollback_hook(db, cloudsync_rollback_hook, ctx); -``` - -**On commit**: Increment global db_version and seq counters -**On rollback**: Discard any metadata written during failed transaction - -**Why important**: Maintains consistency between user data and CRDT metadata without user intervention. - -### 6. Virtual Table Interface Pattern - -Implements SQLite's virtual table mechanism (`src/sqlite/cloudsync_changes_sqlite.c`) for queryable sync state: - -```sql --- No actual 'cloudsync_changes' table exists—it's virtual -SELECT tbl, pk, colname, colvalue FROM cloudsync_changes -WHERE tbl='users' AND db_version > 100; -``` - -**Implementation**: -- `xConnect/xDisconnect` - setup/teardown -- `xBestIndex` - query optimization hints -- `xFilter` - execute query over metadata tables -- Results generated on-demand, no storage - -**Benefit**: Standard SQL interface to sync internals for debugging and monitoring. - -### 7. Binary Payload Serialization Pattern - -Custom wire format in `pk.c` optimized for SQLite data types: - -``` -[num_cols:1 byte][type+len:1 byte][value:N bytes][type+len:1 byte][value:N bytes]... -``` - -**Features**: -- Platform-independent endianness handling (htonl/ntohl for network byte order) -- Variable-length encoding (only bytes needed) -- Type-aware (knows SQLite INTEGER/FLOAT/TEXT/BLOB/NULL) -- LZ4 compression applied to entire payload - -**Why custom format?** More efficient than JSON/protobuf for SQLite's type system; minimizes network bandwidth. - -### 8. Context/Handle Pattern - -Encapsulated state management with opaque pointers: - -```c -cloudsync_context // Per-database state - ├─ site_id // This database's UUID - ├─ db_version, seq // Global counters - ├─ insync flag // Transaction state - └─ cloudsync_table_context[] // Array of synced tables - ├─ table_name - ├─ algo (CLS/GOS/DWS/AWS) - ├─ column metadata - └─ prepared statements -``` - -**Benefits**: -- Multiple databases can have independent sync contexts -- Clean lifecycle: `cloudsync_context_create()` → `cloudsync_context_init()` → `cloudsync_context_free()` -- Opaque pointers (`void *`) hide implementation details -- State passed through SQLite's `sqlite3_user_data()` mechanism - -### 9. Layered Architecture - -Clear separation of concerns from bottom to top: - -``` -┌──────────────────────────────────────┐ -│ SQL Functions (Public API) │ src/sqlite/cloudsync_sqlite.c -│ - cloudsync_init() │ - Registers all SQL functions -│ - cloudsync_uuid() │ - Entry point for users -│ - cloudsync_network_sync() │ -├──────────────────────────────────────┤ -│ Network Layer (Optional) │ src/network.c/h -│ - SQLite Cloud communication │ - Uses libcurl or native APIs -│ - Retry logic, authentication │ - Can be omitted (CLOUDSYNC_OMIT_NETWORK) -├──────────────────────────────────────┤ -│ CRDT Core / Merge Logic │ src/cloudsync.c/h -│ - Payload generation/application │ - Database-agnostic -│ - Vector clock comparison │ - Core sync algorithms -│ - Conflict resolution │ -├──────────────────────────────────────┤ -│ Database Utilities │ src/dbutils.c, src/utils.c -│ - Metadata table management │ - Helper functions -│ - Trigger creation │ - UUID generation -│ - Schema validation │ - Hashing, encoding -├──────────────────────────────────────┤ -│ Database Abstraction Layer │ src/database.h -│ - Generic DB operations │ src/sqlite/database_sqlite.c -│ - Prepared statements │ src/postgresql/database_postgresql.c -│ - Memory allocation │ -├──────────────────────────────────────┤ -│ Database Engine (SQLite/PostgreSQL) │ -└──────────────────────────────────────┘ -``` - -**Key insight**: CRDT logic in `cloudsync.c` never calls SQLite directly—only uses `database.h` abstractions. This enables potential PostgreSQL support. - -### 10. Platform Abstraction Pattern - -Conditional compilation for platform-specific features: - -```c -// Detect platform (utils.h) -#if defined(_WIN32) && !defined(__ANDROID__) && !defined(__EMSCRIPTEN__) - #define CLOUDSYNC_DESKTOP_OS 1 -#elif defined(__APPLE__) && TARGET_OS_OSX - #define CLOUDSYNC_DESKTOP_OS 1 -#elif defined(__linux__) && !defined(__ANDROID__) - #define CLOUDSYNC_DESKTOP_OS 1 -#endif - -// Enable features conditionally -#ifdef CLOUDSYNC_DESKTOP_OS - // File I/O helpers available - bool cloudsync_file_write(const char *path, ...); -#endif - -#ifdef NATIVE_NETWORK - // Use NSURLSession on macOS instead of libcurl -#endif -``` - -**Build system** (`Makefile`): -- Auto-detects platform -- Compiles only needed code (no file I/O on mobile) -- Links platform-specific libraries (Security.framework on macOS) - -## Key Design Principles - -1. **Non-invasive**: User tables unchanged; sync metadata stored separately -2. **Declarative**: Triggers + CRDT = automatic synchronization -3. **Self-contained**: Statically links dependencies (curl); single .so/.dylib file -4. **Extensible**: Multiple CRDT algorithms, virtual tables, custom SQL functions -5. **Efficient**: Binary payloads, column-level tracking, minimal metadata overhead -6. **Portable**: Compiles for Linux/macOS/Windows/Android/iOS/WASM with same codebase - -## Performance Considerations - -### Hot-Path vs. Cold-Path SQL - -The extension distinguishes between performance-critical and initialization code: - -**Hot-path operations** (executed on every user write or during merge): -- **MUST use pre-prepared statements** stored in the context -- Triggers fire on every INSERT/UPDATE/DELETE -- CRDT merge logic processes every incoming change -- SQL compilation overhead is unacceptable here - -**Examples of hot-path code:** -- Trigger bodies that insert into `{table}_cloudsync` -- `merge_insert()` and `merge_insert_col()` in `cloudsync.c` -- Queries in `cloudsync_payload_apply()` that check/update metadata -- Any code path executed within `cloudsync_commit_hook()` - -**Implementation pattern:** -```c -// Prepared statements stored in cloudsync_table_context: -typedef struct cloudsync_table_context { - // ... other fields ... - sqlite3_stmt *insert_meta_stmt; // Pre-compiled - sqlite3_stmt *update_sentinel_stmt; // Pre-compiled - sqlite3_stmt *check_pk_stmt; // Pre-compiled -} cloudsync_table_context; - -// Used in hot-path without recompilation: -int rc = sqlite3_bind_text(table->insert_meta_stmt, 1, pk, pklen, SQLITE_STATIC); -rc = sqlite3_step(table->insert_meta_stmt); -sqlite3_reset(table->insert_meta_stmt); -``` - -**Cold-path operations** (initialization, setup, infrequent operations): -- Can use runtime-compiled SQL via `sqlite3_exec()` or one-off `sqlite3_prepare_v2()` -- Executed once per table initialization or configuration change -- Performance is not critical - -**Examples of cold-path code:** -- `cloudsync_init_table()` - creates metadata tables and triggers -- `dbutils_settings_init()` - sets up global configuration -- Schema validation in `dbutils_table_sanity_check()` -- `cloudsync_cleanup()` - drops metadata tables - -**Implementation pattern:** -```c -// OK for initialization code: -char *sql = sqlite3_mprintf("CREATE TABLE IF NOT EXISTS %s_cloudsync (...)", table_name); -int rc = sqlite3_exec(db, sql, NULL, NULL, NULL); -sqlite3_free(sql); -``` - -### Why This Matters - -1. **Trigger overhead**: Triggers execute on every user operation. Compiling SQL on each trigger execution would make writes unacceptably slow. - -2. **Merge performance**: `cloudsync_payload_apply()` may process thousands of changes in a single sync. SQL compilation would dominate runtime. - -3. **Memory efficiency**: Prepared statements are parsed once, reused many times, and cleaned up when the context is freed. - -### Finding Prepared Statements in the Code - -- Prepared statements initialized in `cloudsync_init_table()` and stored in `cloudsync_table_context` -- Look for `sqlite3_stmt *` fields in context structures -- Lifetime: created during table init, reset after each use, finalized when context freed -- See `cloudsync.c` and `dbutils.c` for examples - -## Testing Strategy - -Tests are in `test/unit.c`. The test framework: -- Uses in-memory SQLite databases -- Tests core CRDT operations (insert, update, delete, merge) -- Validates multi-device sync scenarios -- Checks payload serialization/deserialization -- Compiled with `-DCLOUDSYNC_UNITTEST` flag - -To add tests: -1. Add test function in `test/unit.c` -2. Call from `main()` -3. Run `make test` to execute - -## Important Constraints - -### Primary Key Requirements - -Tables must use TEXT primary keys with globally unique identifiers: -- Use `cloudsync_uuid()` for UUID generation -- Integer auto-increment PKs cause conflicts across devices -- All PK columns must be `NOT NULL` - -### Column Constraints - -For CRDT merge to work correctly: -- All `NOT NULL` columns (except PKs) must have `DEFAULT` values -- This ensures column-by-column merge doesn't violate constraints - -### Triggers and Foreign Keys - -- Foreign key constraints may conflict with CRDT merge (see README for details) -- Triggers on synced tables may execute multiple times during merge -- Test thoroughly when using FKs or triggers with synced tables - -## Code Style Notes - -- Error handling via return codes (SQLITE_OK, SQLITE_ERROR, etc.) -- Memory allocation through abstraction layer (`cloudsync_memory_*` macros) -- Debug macros throughout (disabled by default): `DEBUG_FUNCTION`, `DEBUG_SQL`, etc. -- Hash tables via khash.h (header-only library) -- Compression via LZ4 for payloads -- Comments and documentation must be written in English unless explicitly asked otherwise, even if the prompt is in another language. -- Table names to augment are limited to 512 characters; size buffer allocations for SQL strings accordingly. -- Prefer static buffer allocation with `sqlite3_snprintf` for SQL string construction when practical (e.g., fixed pattern plus table name with a 1024-byte buffer) instead of dynamic `sqlite3_mprintf` to reduce allocations and cleanup. -- SQL statements: - - Parameterless SQL should live as global constants in `src//database_.c` (e.g., `const char *SQL_CREATE_SETTINGS = "CREATE TABLE ...";` in `src/sqlite/database_sqlite.c`) and be used via `extern const char *SQL_CREATE_SETTINGS;` so database backends can override as needed. - - Parameterized SQL must be provided via functions in the database layer (as with `database_count_pk`) so each backend can build statements appropriately. - - Put backend-specific SQL templates in `src//sql_.c`; add a `database_.c` helper (exposed in `database.h`) whenever placeholder rules, quoting/escaping, or catalog-driven SQL generation differ between backends. -- Preserve existing coding style and patterns (e.g., prepared statements with bind/step/reset, use `cloudsync_memory_*` macros, return SQLite error codes). Ask the user before significant structural changes or refactors. - -## PostgreSQL Database Backend Patterns - -- SPI usage: prefer `SPI_execute()` for one-shot catalog queries and `SPI_prepare` + `SPI_execute_plan` for reusable statements. -- Error handling: wrap SPI calls in `PG_TRY()/PG_CATCH()`, capture with `CopyErrorData()`, call `cloudsync_set_error(...)`, and `FlushErrorState()`; helpers should not rethrow. -- Statement lifecycle: `databasevm_prepare/step/reset/finalize` owns a `pg_stmt_t` with `stmt_mcxt`, plus `bind_mcxt` and `row_mcxt` subcontexts; reset uses `MemoryContextReset` (not free). -- Cursor strategy: use portals (`SPI_cursor_open`/`SPI_cursor_fetch`) only for cursorable plans (check `SPI_is_cursor_plan`); non-cursorable plans execute once. -- Binding: bind arrays (`values`, `nulls`, `types`) live in `bind_mcxt` and are cleared in `databasevm_clear_bindings`. -- Row access: extract values via `SPI_getbinval` with OID checks, convert to C types, and copy into cloudsync-managed buffers. -- SQL construction: prefer `snprintf` into fixed buffers, fall back to `cloudsync_memory_mprintf` for dynamic sizes. -- SPI context: helpers assume the caller has already executed `SPI_connect()`; they avoid managing SPI connection state.

: Tables must currently be created manually in PostgreSQL before synchronization.
 We are implementing automatic translation of SQLite CREATE TABLE statements to PostgreSQL syntax. +* **Row-Level Security**: RLS is fully implemented for SQLiteCloud servers.
PostgreSQL RLS integration is in progress and will be included in the final release. +* **Beta Status**

It extends standard SQLite tables with built-in support for offline work and automatic synchronization, allowing multiple devices to operate independently—even without a network connection—and seamlessly stay in sync. With SQLite Sync, developers can easily build **distributed, collaborative applications** while continuing to rely on the **simplicity, reliability, and performance of SQLite**.

If a subsequent non-NULL value decodes to a different type, the plan fails. The fix maps column types to their decoded equivalents so NULL and non-NULL values always use consistent types (e.g., all integers use INT8OID, all floats use FLOAT8OID, most others use TEXTOID). Add map_column_oid_to_decoded_oid() to map column types to their decoded equivalents (INT2/4/8 → INT8, FLOAT4/8/NUMERIC → FLOAT8, BYTEA → BYTEA, others → TEXT). This ensures NULL and non-NULL values bind with the same type, preventing "there is no parameter $N" errors when NULL is synced before non-NULL values for the same column. Add tests 23 and 24 for UUID columns and comprehensive nullable type coverage (INT2/4/8, FLOAT4/8, NUMERIC, BYTEA, TEXT, VARCHAR, CHAR, UUID, JSON, JSONB, DATE, TIMESTAMP). * fix(postgres): add bigint to boolean cast for BOOLEAN column sync BOOLEAN values are encoded as INT8 in sync payloads for SQLite interoperability, but PostgreSQL has no built-in cast from bigint to boolean. Add a custom ASSIGNMENT cast that enables BOOLEAN columns to sync correctly. The cast uses ASSIGNMENT context (not IMPLICIT) to avoid unintended conversions in WHERE clauses while still enabling INSERT/UPDATE operations used by merge_insert. The write direction (BOOL → INT encoding flow) "just works" because DatumGetBool() naturally returns 0 or 1. The problem was only on the read side where PostgreSQL refused to cast the decoded INT8 back to BOOLEAN without our custom cast. * feat(commands): add sync roundtrip RLS test guide * bump version * ci: add postgres-test job to main workflow * ci(Makefile.postgresql): replaced all docker-compose commands with docker compose (v2 plugin syntax) Fix the execution in the github actions runner: The GitHub Actions runner has docker compose (v2 plugin) but not the standalone docker-compose (v1) * ci: fix the "run postgresql tests" step --- .claude/commands/test-sync-roundtrip-rls.md | 532 ++++++++++++++++++ .github/workflows/main.yml | 33 +- docker/Makefile.postgresql | 30 +- src/cloudsync.c | 22 +- src/cloudsync.h | 2 +- src/postgresql/cloudsync--1.0.sql | 18 + src/postgresql/cloudsync_postgresql.c | 89 ++- src/postgresql/database_postgresql.c | 5 +- test/postgresql/01_unittest.sql | 2 +- .../postgresql/20_init_with_existing_data.sql | 298 ++++++++++ test/postgresql/21_null_value_sync.sql | 194 +++++++ test/postgresql/22_null_column_roundtrip.sql | 347 ++++++++++++ test/postgresql/23_uuid_column_roundtrip.sql | 359 ++++++++++++ .../24_nullable_types_roundtrip.sql | 495 ++++++++++++++++ test/postgresql/25_boolean_type_issue.sql | 241 ++++++++ test/postgresql/full_test.sql | 6 + 16 files changed, 2641 insertions(+), 32 deletions(-) create mode 100644 .claude/commands/test-sync-roundtrip-rls.md create mode 100644 test/postgresql/20_init_with_existing_data.sql create mode 100644 test/postgresql/21_null_value_sync.sql create mode 100644 test/postgresql/22_null_column_roundtrip.sql create mode 100644 test/postgresql/23_uuid_column_roundtrip.sql create mode 100644 test/postgresql/24_nullable_types_roundtrip.sql create mode 100644 test/postgresql/25_boolean_type_issue.sql diff --git a/.claude/commands/test-sync-roundtrip-rls.md b/.claude/commands/test-sync-roundtrip-rls.md new file mode 100644 index 0000000..38e496c --- /dev/null +++ b/.claude/commands/test-sync-roundtrip-rls.md @@ -0,0 +1,532 @@ +# Sync Roundtrip Test with RLS + +Execute a full roundtrip sync test between multiple local SQLite databases and the local Supabase Docker PostgreSQL instance, verifying that Row Level Security (RLS) policies are correctly enforced during sync. + +## Prerequisites +- Supabase Docker container running (PostgreSQL on port 54322) +- HTTP sync server running on http://localhost:8091/postgres +- Built cloudsync extension (`make` to build `dist/cloudsync.dylib`) + +## Test Procedure + +### Step 1: Get DDL from User + +Ask the user to provide a DDL query for the table(s) to test.

Key differences: +- SQLite uses `INTEGER PRIMARY KEY` for auto-increment, PostgreSQL uses `SERIAL` or `BIGSERIAL` +- SQLite uses `TEXT`, PostgreSQL can use `TEXT` or `VARCHAR` +- PostgreSQL has more specific types like `TIMESTAMPTZ`, SQLite uses `TEXT` for dates +- For UUID primary keys, SQLite uses `TEXT`, PostgreSQL uses `UUID` +- For `user_id UUID`, SQLite uses `TEXT` + +### Step 4: Setup PostgreSQL with RLS + +Connect to Supabase PostgreSQL and prepare the environment: +```bash +psql postgresql://supabase_admin:postgres@127.0.0.1:54322/postgres +``` + +Inside psql: +1. List existing tables with `\dt` to find any `_cloudsync` metadata tables +2. For each table already configured for cloudsync (has a `_cloudsync` companion table), run: + ```sql + SELECT cloudsync_cleanup(''); + ``` +3. Drop the test table if it exists: `DROP TABLE IF EXISTS CASCADE;` +4. Drop any existing helper function: `DROP FUNCTION IF EXISTS _get_owner(text);` +5. Create the test table using the PostgreSQL DDL +6. Enable RLS on the table: + ```sql + ALTER TABLE ENABLE ROW LEVEL SECURITY; + ``` +7. Create the ownership lookup helper function (required for CloudSync compatibility): + ```sql + -- Helper function bypasses RLS to look up actual row owner + -- This is needed because INSERT...ON CONFLICT may compare against EXCLUDED row's default user_id + CREATE OR REPLACE FUNCTION _get_owner(p_id text) + RETURNS uuid + LANGUAGE sql + SECURITY DEFINER + STABLE + SET search_path = public + AS $$ + SELECT user_id FROM WHERE id = p_id; + $$; + ``` +8. Create RLS policies based on the user's description. Example for "user can only access their own rows": + ```sql + -- SELECT: User can see rows they own + -- Helper function fallback handles ON CONFLICT edge cases where user_id resolves to EXCLUDED row + CREATE POLICY "select_own_rows" ON + FOR SELECT USING ( + auth.uid() = user_id + OR auth.uid() = _get_owner(id) + ); + + -- INSERT: Allow if user_id matches auth.uid() OR is default (cloudsync staging) + CREATE POLICY "insert_own_rows" ON + FOR INSERT WITH CHECK ( + auth.uid() = user_id + OR user_id = '00000000-0000-0000-0000-000000000000'::uuid + ); + + -- UPDATE: Check ownership via explicit lookup, allow default for staging + CREATE POLICY "update_own_rows" ON + FOR UPDATE + USING ( + auth.uid() = user_id + OR auth.uid() = _get_owner(id) + OR user_id = '00000000-0000-0000-0000-000000000000'::uuid + ) + WITH CHECK ( + auth.uid() = user_id + OR user_id = '00000000-0000-0000-0000-000000000000'::uuid + ); + + -- DELETE: User can only delete rows they own + CREATE POLICY "delete_own_rows" ON + FOR DELETE USING ( + auth.uid() = user_id + ); + ``` +9. Initialize cloudsync: `SELECT cloudsync_init('');` +10. Insert some initial test data (optional, can be done via SQLite clients) + +**Why these specific policies?** +CloudSync uses `INSERT...ON CONFLICT DO UPDATE` for field-by-field synchronization. During conflict detection, PostgreSQL's RLS may compare `auth.uid()` against the EXCLUDED row's `user_id` (which has the default value) instead of the existing row's `user_id`. The helper function explicitly looks up the existing row's owner to work around this issue.

Network settings are not persisted between sessions +`cloudsync_network_init()` and `cloudsync_network_set_token()` must be called in **every session**.

All 84 SQLite tests and 26 PostgreSQL tests pass with 0 failures and 0 memory leaks. ## src/cloudsync.c (13 fixes) - [HIGH] Guard NULL db_version_stmt in cloudsync_dbversion_rerun — set db_version = CLOUDSYNC_MIN_DB_VERSION and return 0 when stmt is NULL, preventing NULL dereference after schema rebuild failure - [MEDIUM] Add early return for NULL stmt in dbvm_execute to prevent crash when called with uninitialized statement pointer - [MEDIUM] Change (bool)dbvm_count() to (dbvm_count() > 0) in table_pk_exists — prevents negative return values being cast to true, giving false positive "pk exists" results - [MEDIUM] Add NULL check on database_column_text result in cloudsync_refill_metatable before calling strlen — prevents crash on corrupted or empty column data - [MEDIUM] Route early returns in cloudsync_payload_apply through goto cleanup so CLEANUP callback and vm finalize always run — prevents resource leaks and callback contract violation - [MEDIUM] Change return false to goto abort_add_table when ROWIDONLY rejected — ensures table_free runs on the partially allocated table, preventing memory leak - [MEDIUM] Initialize *persistent = false at top of cloudsync_colvalue_stmt — prevents use of uninitialized value when table_lookup returns NULL - [LOW] Add NULL check on database_column_blob in merge_did_cid_win — prevents memcmp with NULL pointer on corrupted cloudsync table - [LOW] Handle partial failure in table_add_to_context_cb — clean up col_name, col_merge_stmt, col_value_stmt at index on error instead of leaving dangling pointers - [LOW] Remove unused pragma_checked field from cloudsync_context - [LOW] Change pointer comparison to strcmp in cloudsync_set_schema — pointer equality missed cases where different string pointers had identical content - [LOW] Fix cloudsync_payload_get NULL check: blob == NULL (always false for char** arg) changed to *blob == NULL - [LOW] Pass extra meta_ref args to SQL_CLOUDSYNC_UPSERT_COL_INIT_OR_BUMP_VERSION mprintf call to match updated PostgreSQL format string ## src/sqlite/cloudsync_sqlite.c (5 fixes) - [HIGH] Split DEFAULT_FLAGS into FLAGS_PURE (SQLITE_UTF8 | SQLITE_INNOCUOUS | SQLITE_DETERMINISTIC) and FLAGS_VOLATILE (SQLITE_UTF8). Pure functions: cloudsync_version, cloudsync_pk_encode, cloudsync_pk_decode. All others volatile — fixes cloudsync_uuid() returning identical values within the same query when SQLite cached deterministic results - [HIGH] Fix realloc inconsistency in dbsync_update_payload_append: on second realloc failure, state was inconsistent (new_values resized, old_values not, capacity not updated). Both reallocs now checked before updating pointers and capacity - [MEDIUM] Move payload->count++ after all database_value_dup NULL checks in dbsync_update_payload_append — prevents count increment when allocation failed, which would cause use-after-free on cleanup - [MEDIUM] Add dbsync_update_payload_free(payload) before 3 early returns in dbsync_update_final — prevents memory leak of entire aggregate payload on error paths - [MEDIUM] Clean up partial database_value_dup allocations on OOM in dbsync_update_payload_append — free dup'd values at current index when count is not incremented to prevent leak ## src/sqlite/database_sqlite.c (6 fixes) - [MEDIUM] Replace fixed 4096-byte trigger WHEN clause buffers with dynamic cloudsync_memory_mprintf — prevents silent truncation for tables with long filter expressions - [MEDIUM] Check cloudsync_memory_mprintf return for NULL before storing in col_names[] in database_build_trigger_when — prevents strlen(NULL) crash in filter_is_column under OOM - [LOW] Use consistent PRId64 format with (int64_t) cast for schema hash in database_check_schema_hash and database_update_schema_hash — prevents format string mismatch on platforms where uint64_t and int64_t have different printf specifiers - [LOW] Fix DEBUG_DBFUNCTION using undeclared variable 'table' instead of 'table_name' in database_create_metatable (line 568) and database_create_triggers (line 782) — compile error when debug macros enabled - [LOW] Remove dead else branch in database_pk_rowid — unreachable code after sqlite3_prepare_v2 success check ## src/sqlite/sql_sqlite.c (1 fix) - [MEDIUM] Change %s to %q in SQL_INSERT_SETTINGS_STR_FORMAT — prevents SQL injection via malformed setting key/value strings ## src/dbutils.c (1 fix) - [MEDIUM] Change snprintf to cloudsync_memory_mprintf for settings insert using the new %q format — ensures proper SQL escaping ## src/utils.c (1 fix) - [MEDIUM] Fix integer overflow in cloudsync_blob_compare: (int)(size1 - size2) overflows for large size_t values, changed to (size1 > size2) ? 1 : -1 ## src/network.c (1 fix) - [MEDIUM] Remove trailing semicolon from savepoint name "cloudsync_logout_savepoint;" — semicolon in name caused savepoint/release mismatch ## src/postgresql/sql_postgresql.c (1 fix) - [CRITICAL] Replace EXCLUDED.col_version with %s.col_version (table reference) in SQL_CLOUDSYNC_UPSERT_COL_INIT_OR_BUMP_VERSION — PostgreSQL EXCLUDED refers to the proposed INSERT row (always col_version=1), not the existing row. This caused col_version to never increment correctly on conflict, breaking CRDT merge logic ## src/postgresql/cloudsync_postgresql.c (4 fixes) - [HIGH] Change PG_RETURN_INT32(rc) to PG_RETURN_BOOL(rc == DBRES_OK) in pg_cloudsync_terminate — SQL declaration returns BOOLEAN but code returned raw integer, causing protocol mismatch - [HIGH] Copy blob data with palloc+memcpy before databasevm_reset in cloudsync_col_value, and fix PG_RETURN_CSTRING to PG_RETURN_BYTEA_P — reset invalidates SPI tuple memory, causing use-after-free; wrong return type caused type mismatch with SQL declaration - [MEDIUM] Use palloc0 instead of cloudsync_memory_alloc+memset in aggregate context — palloc0 is lifetime-safe in PG aggregate memory context; cloudsync_memory_alloc uses wrong allocator - [MEDIUM] Free SPI_tuptable in all paths of get_column_oid — prevents SPI tuple table leak on early return ## src/postgresql/database_postgresql.c (3 fixes) - [MEDIUM] Use sql_escape_identifier for table_name/schema in CREATE INDEX — prevents SQL injection via specially crafted table names - [MEDIUM] Use sql_escape_literal for table_name in trigger WHEN clause — prevents SQL injection in trigger condition - [LOW] Use SPI_getvalue instead of DatumGetName for type safety in database_pk_names — DatumGetName assumes Name type which may not match the actual column type from information_schema ## test/unit.c (3 new tests) - do_test_blob_compare_large_sizes: verifies overflow fix for large size_t values in cloudsync_blob_compare - do_test_deterministic_flags: verifies cloudsync_uuid() returns different values in same query (non-deterministic flag working) - do_test_schema_hash_consistency: verifies int64 hash format roundtrip through cloudsync_schema_versions table Co-Authored-By: Claude Opus 4.6 * Bump version to 0.9.111 Co-Authored-By: Claude Opus 4.6 * Update .gitignore --- .gitignore | 1 + src/cloudsync.c | 75 ++++++++++------- src/cloudsync.h | 2 +- src/dbutils.c | 12 +-- src/network.c | 2 +- src/postgresql/cloudsync_postgresql.c | 49 +++++++---- src/postgresql/database_postgresql.c | 44 ++++++---- src/postgresql/sql_postgresql.c | 4 +- src/sqlite/cloudsync_sqlite.c | 72 +++++++++++----- src/sqlite/database_sqlite.c | 58 +++++++------ src/sqlite/sql_sqlite.c | 4 +- src/utils.c | 2 +- test/unit.c | 116 ++++++++++++++++++++++++++ 13 files changed, 317 insertions(+), 124 deletions(-) diff --git a/.gitignore b/.gitignore index 646d00e..85541ce 100644 --- a/.gitignore +++ b/.gitignore @@ -50,3 +50,4 @@ jniLibs/ .DS_Store Thumbs.db CLAUDE.md +*.o diff --git a/src/cloudsync.c b/src/cloudsync.c index fc18905..12c0e90 100644 --- a/src/cloudsync.c +++ b/src/cloudsync.c @@ -115,7 +115,6 @@ struct cloudsync_context { void *aux_data;

Example: {"send":{"status":"synced","localVersion":5,"serverVersion":5},"receive":{"rows":3,"tables":["tasks"]}} * Feat/network support for multi org cloudsync (#11) * Disable notnull prikey constraints (#12) * The cloudsync extension now enforces NULL primary key rejection at runtime (any write with a NULL PK returns an error), so the explicit NOT NULL constraint on primary key columns is no longer a schema requirement * test: add null primary key rejection tests for SQLite and PostgreSQL * docs: remove NOT NULL requirement from primary key definitions The extension now enforces NULL primary key rejection at runtime, so the explicit NOT NULL constraint on PK columns is no longer a schema requirement. Replace the "must be NOT NULL" guidance with a note about runtime enforcement. * docs: add first draft of PERFORMANCE.md and CHANGELOG.md * fix(postgresql): resolve commit_alter crash and BYTEA handling in column_text Guard savepoint commit/rollback against missing subtransactions to prevent segfault in autocommit mode. Add BYTEA support to database_column_text so encoded PKs are readable during refill_metatable after ALTER TABLE. Enable alter table sync test (31). * test: new alter table test for postgres * feat: update endpoints to use databaseMangedId for /v2/cloudsync api * feat(network)!: replace URL connection string with a UUID (managedDatabaseId) BREAKING CHANGE: cloudsync_network_init now accepts a UUID string instead of the previous URL string. URL connection strings are no longer accepted. The managed database identifier returned by the CloudSync service when a new database is registered for sync. For SQLiteCloud projects, this value can be obtained from the project's OffSync page on the dashboard. * docs: update docs for the new managedDatabaseId arg for cloudsync_network_init * docs(examples): update example for the new managedDatabaseId arg for cloudsync_network_init --- .../commands/stress-test-sync-sqlitecloud.md | 192 +++++ .../test-sync-roundtrip-sqlitecloud-rls.md | 468 ++++++++++++ ...md => test-sync-roundtrip-supabase-rls.md} | 90 ++- ...rip.md => test-sync-roundtrip-supabase.md} | 60 +- API.md | 84 ++- CHANGELOG.md | 50 ++ PERFORMANCE.md | 190 +++++ README.md | 46 +- docker/Makefile.postgresql | 4 +- docs/Network.md | 8 - docs/postgresql/CLIENT.md | 16 +- docs/postgresql/RLS.md | 192 +++++ docs/postgresql/SUPABASE.md | 2 +- examples/simple-todo-db/README.md | 18 +- examples/sport-tracker-app/.env.example | 5 +- .../src/db/sqliteSyncOperations.ts | 8 +- examples/to-do-app/.env.example | 7 +- examples/to-do-app/components/SyncContext.js | 12 +- examples/to-do-app/hooks/useCategories.js | 8 +- plans/BATCH_MERGE_AND_RLS.md | 166 +++++ plans/ISSUE_POSTGRES_SCHEMA.md | 73 -- .../ISSUE_WARNING_resource_was_not_closed.md | 64 -- plans/PG_CLOUDSYNC_CHANGES_COL_VALUE_BYTEA.md | 104 --- plans/POSTGRESQL_IMPLEMENTATION.md | 583 --------------- plans/TODO.md | 81 +-- src/cloudsync.c | 516 +++++++++++--- src/cloudsync.h | 24 +- src/database.h | 11 +- src/jsmn.h | 471 +++++++++++++ src/network.c | 666 ++++++++++++------ src/network.m | 64 +- src/network_private.h | 10 +- src/pk.c | 11 +- src/pk.h | 2 + src/postgresql/cloudsync_postgresql.c | 18 +- src/postgresql/database_postgresql.c | 214 ++++-- src/sqlite/cloudsync_sqlite.c | 17 +- src/sqlite/database_sqlite.c | 150 +++- test/integration.c | 55 +- test/postgresql/27_rls_batch_merge.sql | 356 ++++++++++ test/postgresql/28_db_version_tracking.sql | 275 ++++++++ test/postgresql/29_rls_multicol.sql | 435 ++++++++++++ test/postgresql/30_null_prikey_insert.sql | 68 ++ test/postgresql/31_alter_table_sync.sql | 383 ++++++++++ test/postgresql/full_test.sql | 6 + test/unit.c | 490 +++++++------ 46 files changed, 5018 insertions(+), 1755 deletions(-) create mode 100644 .claude/commands/stress-test-sync-sqlitecloud.md create mode 100644 .claude/commands/test-sync-roundtrip-sqlitecloud-rls.md rename .claude/commands/{test-sync-roundtrip-rls.md => test-sync-roundtrip-supabase-rls.md} (83%) rename .claude/commands/{test-sync-roundtrip.md => test-sync-roundtrip-supabase.md} (64%) create mode 100644 CHANGELOG.md create mode 100644 PERFORMANCE.md create mode 100644 docs/postgresql/RLS.md create mode 100644 plans/BATCH_MERGE_AND_RLS.md delete mode 100644 plans/ISSUE_POSTGRES_SCHEMA.md delete mode 100644 plans/ISSUE_WARNING_resource_was_not_closed.md delete mode 100644 plans/PG_CLOUDSYNC_CHANGES_COL_VALUE_BYTEA.md delete mode 100644 plans/POSTGRESQL_IMPLEMENTATION.md create mode 100644 src/jsmn.h create mode 100644 test/postgresql/27_rls_batch_merge.sql create mode 100644 test/postgresql/28_db_version_tracking.sql create mode 100644 test/postgresql/29_rls_multicol.sql create mode 100644 test/postgresql/30_null_prikey_insert.sql create mode 100644 test/postgresql/31_alter_table_sync.sql diff --git a/.claude/commands/stress-test-sync-sqlitecloud.md b/.claude/commands/stress-test-sync-sqlitecloud.md new file mode 100644 index 0000000..2540008 --- /dev/null +++ b/.claude/commands/stress-test-sync-sqlitecloud.md @@ -0,0 +1,192 @@ +# Sync Stress Test with remote SQLiteCloud database + +Execute a stress test against the CloudSync server using multiple concurrent local SQLite databases syncing large volumes of CRUD operations simultaneously.

If you sync frequently, D stays small regardless of how large the database grows. The per-operation overhead on writes is proportional to the number of columns in the affected row, not to the table size. This is fundamentally different from sync solutions that diff or scan the full dataset. + +## Breaking Down the Cost + +The overhead introduced by the extension can be decomposed into four independent concerns: + +### 1. Per-Operation Overhead (Write-Path Cost) + +Every INSERT, UPDATE, or DELETE on a synced table fires AFTER triggers that write CRDT metadata into a companion `
_cloudsync` table. This happens synchronously, inline with the original write. + +| Operation | Metadata Rows Written | Complexity | +|-----------|----------------------|------------| +| INSERT | 1 sentinel + 1 per non-PK column | O(C) | +| UPDATE | 1 per changed column (NEW != OLD) | O(C_changed) <= O(C) | +| DELETE | 1 sentinel + cleanup of existing metadata | O(C_existing) | + +Where **C** = number of non-PK columns in the table. + +**Key point:** This cost is **constant per row** and independent of the total number of rows in the table (N). Writing to a 100-row table costs the same as writing to a 10-million-row table. The metadata table uses a composite primary key `(pk, col_name)` with `WITHOUT ROWID` optimization (SQLite) or a standard B-tree primary key (PostgreSQL), so the index update cost is O(log M) where M is the metadata table size -- but this is the same cost as any indexed INSERT and is negligible in practice. + +### 2. Sync Operations (Push & Pull) + +These are the operations that create and apply sync payloads. They are synchronous in the extension and should typically be run by the application off the main thread. + +#### Push: Payload Generation + +``` +Cost: O(D) where D = number of column-level changes since last sync +``` + +The push operation queries `cloudsync_changes`, which dynamically reads from all synced `
_cloudsync` tables: +```sql +SELECT ... FROM cloudsync_changes WHERE db_version > +``` + +Each metadata table has an **index on `db_version`**, so payload generation scales primarily with the number of new changes, plus a small per-synced-table overhead to construct the `cloudsync_changes` query. It does not diff the full dataset. In SQLite, each changed column also performs a primary-key lookup in the base table to retrieve the current value. + +The resulting payload is LZ4-compressed before transmission. + +#### Pull: Payload Application + +``` +Cost: O(D) to decode + O(D_unique_pks) to merge into the database +``` + +Incoming changes are decoded and **batched by primary key**. All column changes for the same row are accumulated and flushed as a single UPDATE or INSERT statement. This batching reduces the number of actual database writes to one per affected row, regardless of how many columns changed. + +Conflict resolution (CRDT merge) is O(1) per column: it compares version numbers and, only if tied, falls back to value comparison and site-id tiebreaking. No global state or table scan is required. + +#### Summary + +| Phase | Scales With | Does NOT Scale With | +|-------|-------------|-------------------| +| Payload generation | D (changes since last sync) | N (total rows) | +| Payload application | D (incoming changes) | N (total rows) | +| Conflict resolution | D (conflicting columns) | N (total rows) | + +**This means sync time is driven mainly by delta size (`D`) rather than total database size (`N`)**. As long as the number of changes between syncs stays bounded, sync time remains roughly stable even as the database grows. + +### 3. Sync Frequency & Network Latency + +When the application runs sync off the main thread, perceived latency depends on: + +- **Sync interval**: How often the app triggers a push/pull cycle. More frequent syncs mean smaller deltas (smaller D) and faster individual sync operations, at the cost of more network round-trips. +- **Network latency**: The round-trip time to the sync server. LZ4 compression reduces payload size, but latency is dominated by the network hop itself for small deltas. +- **Payload size**: Proportional to D x average column value size. Large BLOBs or TEXT values will increase transfer time linearly. + +The extension does not impose a sync schedule -- the application controls when and how often to sync. A typical pattern is to sync on a timer (e.g., every 5-30 seconds) or on specific events (app foreground, user action). + +### 4. Metadata Storage Overhead + +Each synced table has a companion `
_cloudsync` metadata table with the following schema: + +``` +PRIMARY KEY (pk, col_name) -- WITHOUT ROWID (SQLite) +Columns: pk, col_name, col_version, db_version, site_id, seq +Index: db_version +``` + +**Storage cost per row in the base table:** +- 1 sentinel row (marks the row's existence/deletion state) +- 1 metadata row per non-PK column that has ever been written + +So for a table with C non-PK columns, the metadata table will contain approximately `N x (1 + C)` rows, where N is the number of rows in the base table. + +**Estimated overhead per metadata row:** +- `pk`: encoded primary key (typically 8-32 bytes depending on PK type and count) +- `col_name`: column name string (shared via SQLite's string interning, typically 5-30 bytes) +- `col_version`, `db_version`, `seq`: 3 integers (8 bytes each = 24 bytes) +- `site_id`: 1 integer (8 bytes) + +Rough estimate: **60-100 bytes per metadata row**, or **60-100 x (1 + C) bytes per base table row**. + +| Base Table | Columns (C) | Rows (N) | Estimated Metadata Size | +|------------|-------------|----------|------------------------| +| Small | 5 | 1,000 | ~360 KB - 600 KB | +| Medium | 10 | 100,000 | ~66 MB - 110 MB | +| Large | 10 | 1,000,000| ~660 MB - 1.1 GB | +| Wide | 50 | 100,000 | ~306 MB - 510 MB | + +**Mitigation strategies:** +- Only sync tables that need it -- not every table requires CRDT tracking. +- Prefer narrow tables (fewer columns) for high-volume data. +- The `WITHOUT ROWID` optimization (SQLite) significantly reduces per-row storage overhead. +- Deleted rows have their per-column metadata cleaned up, but a tombstone sentinel row persists (see section 9 below). + +### 5. Read-Path Overhead + +Normal application reads are not directly instrumented by the extension. No triggers, views, or hooks intercept ordinary SELECT queries on application tables, and the CRDT metadata is stored separately. In practice, read overhead is usually negligible. + +### 6. Initial Sync (First Device) + +When a new device syncs for the first time (`db_version = 0`), the push payload contains the **entire dataset**: every column of every row across all synced tables. The payload size is proportional to `N * C` (total rows times columns). + +The payload is built entirely in memory, starting with a 512 KB buffer (`CLOUDSYNC_PAYLOAD_MINBUF_SIZE` in `src/cloudsync.c`) and growing via `realloc` as needed. Peak memory usage is at least the full uncompressed payload size and can be higher during compression. For a database with 1 million rows and 10 columns of average 50 bytes each, the uncompressed payload could reach ~500 MB before LZ4 compression. + +Subsequent syncs are incremental (proportional to D, changes since the last sync), so the first sync is the expensive one. Applications with large datasets should plan for this -- for example, by seeding new devices from a database snapshot rather than syncing from scratch. + +### 7. WAL and Disk I/O Amplification + +Each write to a synced table generates additional metadata writes via AFTER triggers. The amplification factor depends on the operation: + +| Operation | Total Writes (base + metadata) | Amplification Factor | +|-----------|-------------------------------|---------------------| +| INSERT (C columns) | 1 + 1 sentinel + C metadata | ~C+2x | +| UPDATE (1 column) | 1 + 1 metadata | 2x | +| UPDATE (C columns) | 1 + C metadata | ~C+1x | +| DELETE | 1 + cleanup writes | variable | + +For a table with 10 non-PK columns, an INSERT generates roughly 12 logical row writes instead of 1. This increases WAL/page churn and affects: + +- **Disk I/O**: More pages written per transaction, larger WAL files between checkpoints. +- **WAL checkpoint frequency**: The WAL grows faster, so checkpoints run more often (or the WAL file stays larger if checkpointing is deferred). +- **Battery on mobile**: More disk writes per user action. Batching multiple writes in a single transaction amortizes the transaction overhead but not the per-row metadata cost. + +### 8. Locking During Sync Apply + +Payload application (`cloudsync_payload_apply`) uses savepoints grouped by source `db_version`. On SQLite, each savepoint holds a write lock for its duration. If the application runs sync on the main thread, other work on the same connection is blocked, and reads from other connections may block outside WAL mode. + +On SQLite, using WAL mode prevents readers on other connections from being blocked by writers, which is the recommended configuration for concurrent sync. + +### 9. Metadata Lifecycle (Tombstones and Cleanup) + +When a row is deleted, the per-column metadata rows are removed, but a **tombstone sentinel** (`__[RIP]__`) persists in the metadata table. This tombstone is necessary for propagating deletes to other devices during sync. There is no automatic garbage collection of tombstones -- they accumulate over time. + +Metadata cleanup for **removed columns** (after schema migration) only runs during `cloudsync_finalize_alter()`, which is called as part of the `cloudsync_alter()` workflow. Outside of schema changes, orphaned metadata from dropped columns remains in the metadata table. + +The **site ID table** (`cloudsync_site_id`) also grows monotonically -- one entry per unique device that has ever synced. This is typically small (one row per device) and not a concern in practice. + +For applications with high delete rates, the tombstone accumulation may become significant over time. Consider periodic full re-syncs or application-level archival strategies if this is a concern. + +### 10. Multi-Table Considerations + +The `cloudsync_changes` virtual table (SQLite) or set-returning function (PostgreSQL) dynamically constructs a `UNION ALL` query across all synced tables' metadata tables. The query construction cost scales as O(T) where T is the number of synced tables. + +For most applications (fewer than ~50 synced tables), this is negligible. Applications syncing a very large number of tables should be aware that payload generation involves iterating over all synced tables to check for changes. + +### Platform Differences (SQLite vs PostgreSQL) + +- **SQLite** uses native C triggers registered directly with the SQLite API. Metadata tables use `WITHOUT ROWID` for compact storage. +- **PostgreSQL** uses row-level PL/pgSQL trigger functions that call into C functions via the extension. This adds a small amount of overhead per trigger invocation compared to SQLite's direct C triggers.

The `RELEASE` (commit) at each db_version boundary triggers `cloudsync_commit_hook`, which: +- Saves `pending_db_version` as the new `data->db_version` +- Resets `data->seq = 0` + +This ensures unique `(db_version, seq)` tuples in `cloudsync_changes` across groups. + +**In PostgreSQL SPI, these are dead code**: `database_in_transaction()` returns `true` (via `IsTransactionState()`), so the condition `!database_in_transaction(data)` is always false and `in_savepoint` is never set. This is correct because: +1. PostgreSQL has no equivalent commit hook on subtransaction release +2. The SPI transaction from `SPI_connect` already provides transaction context +3. The inner per-PK savepoint handles the RLS isolation PostgreSQL needs + +**Why a single outer savepoint doesn't work**: We tested replacing per-db_version savepoints with a single savepoint wrapping the entire loop. This broke the `(db_version, seq)` uniqueness invariant in SQLite because the commit hook never fired mid-apply — `data->db_version` never advanced and `seq` never reset. + +### Inner savepoints: per-PK in `merge_flush_pending` + +```c +flush_savepoint = (database_begin_savepoint(data, "merge_flush") == DBRES_OK); +// ... database operations ... +cleanup: + if (flush_savepoint) { + if (rc == DBRES_OK) database_commit_savepoint(data, "merge_flush"); + else database_rollback_savepoint(data, "merge_flush"); + } +``` + +Wraps each PK's flush in a savepoint. On failure (e.g. RLS denial), `database_rollback_savepoint` calls `RollbackAndReleaseCurrentSubTransaction()` in PostgreSQL, which properly releases all executor resources (open relations, snapshots, plan cache) acquired during the failed statement. This eliminates the "resource was not closed" warnings that `SPI_finish` previously emitted. + +In SQLite, when the outer per-db_version savepoint is active, these become harmless nested savepoints. + +### Platform behavior summary + +| Environment | Outer savepoint | Inner savepoint | Effect | +|---|---|---|---| +| **PostgreSQL SPI** | Dead code (`in_transaction` always true) | Active — RLS error isolation + resource cleanup | Only inner savepoint runs | +| **SQLite client** | Active — groups writes, triggers commit hook | Active — nested inside outer, harmless | Both run; outer provides transaction grouping | +| **SQLiteCloud** | Active — groups writes, triggers commit hook | Active — RLS error isolation | Both run; each serves its purpose | + +## SPI and Memory Management + +### Nested SPI levels + +`pg_cloudsync_payload_apply` calls `SPI_connect` (level 1). Inside the loop, `databasevm_step` executes `INSERT INTO cloudsync_changes`, which fires the INSTEAD OF trigger. The trigger calls `SPI_connect` (level 2), runs `merge_insert` / `merge_pending_add`, then `SPI_finish` back to level 1. The deferred `merge_flush_pending` runs at level 1. + +### `database_in_transaction()` in SPI + +Always returns true in SPI context (`IsTransactionState()`). This makes the per-db_version savepoints dead code in PostgreSQL and is why `last_payload_db_version` must be updated unconditionally. + +### Error handling in SPI + +When RLS denies a write, PostgreSQL raises an error inside SPI. The inner per-PK savepoint in `merge_flush_pending` catches this: `RollbackAndReleaseCurrentSubTransaction()` properly releases all executor resources. Without the savepoint, `databasevm_step`'s `PG_CATCH` + `FlushErrorState()` would clear the error stack but leave executor resources orphaned, causing `SPI_finish` to emit "resource was not closed" warnings. + +### Batch cleanup paths + +`batch.entries` is heap-allocated via `cloudsync_memory_realloc` and reused across flushes. Each entry's `col_value` (from `database_value_dup`) is freed by `merge_pending_free_entries` on every flush. The entries array, `cached_vm`, and `cached_col_names` are freed once at the end of `cloudsync_payload_apply`. Error paths (`goto cleanup`, early returns) must free all three and call `merge_pending_free_entries` to avoid leaking `col_value` copies. + +## Batch Apply: Pros and Cons + +The batch path is used for all platforms (SQLite client, SQLiteCloud, PostgreSQL), not just when RLS is active. + +**Pros (even without RLS)**: +- Fewer SQL executions: N winning columns per PK become 1 statement instead of N. Each `databasevm_step` involves B-tree lookup, page modification, WAL write. +- Atomicity per PK: all columns for a PK succeed or fail together. + +**Cons**: +- Dynamic SQL per unique column combination (mitigated by the statement cache). +- Memory overhead: `database_value_dup` copies each column value into the buffer. +- Code complexity: batching structs, flush logic, cleanup paths. + +**Why not maintain two paths**: SQLiteCloud uses the SQLite extension with RLS, so the batch path (UPDATE vs UPSERT selection, per-PK savepoints) is required there. Maintaining a separate single-column path for plain SQLite clients would double the code with marginal benefit. + +## Files Changed + +| File | Change | +|------|--------| +| `src/cloudsync.c` | Batch merge structs with statement cache (`cached_vm`, `cached_col_names`), `merge_pending_add`, `merge_flush_pending` (with per-PK savepoint), `merge_pending_free_entries`; `pending_batch` field on context; `row_exists` propagation in `merge_insert`; batch mode in `merge_sentinel_only_insert`; `last_payload_db_version` fix; removed `payload_apply_callback` | +| `src/cloudsync.h` | Removed `CLOUDSYNC_PAYLOAD_APPLY_STEPS` enum | +| `src/database.h` | Added `sql_build_upsert_pk_and_multi_cols`, `sql_build_update_pk_and_multi_cols`; removed callback typedefs | +| `src/sqlite/database_sqlite.c` | Implemented `sql_build_upsert_pk_and_multi_cols` (dynamic SQL); `sql_build_update_pk_and_multi_cols` (delegates to upsert); removed callback functions | +| `src/postgresql/database_postgresql.c` | Implemented `sql_build_update_pk_and_multi_cols` (meta-query against `pg_catalog` generating typed UPDATE) | +| `test/unit.c` | Removed callback code and `do_test_andrea` debug function (fixed 288048-byte memory leak) | +| `test/postgresql/27_rls_batch_merge.sql` | Tests 1-3 (superuser) + Tests 4-6 (authenticated-role RLS enforcement) | +| `docs/postgresql/RLS.md` | Documented INSERT vs UPDATE paths and partial-column RLS interaction | + +## TODO + + - update documentation: RLS.md, README.md and the https://github.com/sqlitecloud/docs repo diff --git a/plans/ISSUE_POSTGRES_SCHEMA.md b/plans/ISSUE_POSTGRES_SCHEMA.md deleted file mode 100644 index a34b0e2..0000000 --- a/plans/ISSUE_POSTGRES_SCHEMA.md +++ /dev/null @@ -1,73 +0,0 @@ -Issue summary - -cloudsync_init('users') fails in Supabase postgres with: -"column reference \"id\" is ambiguous". -Both public.users and auth.users exist.

The statement finishes, SPI cleanup happens, and any tuptable resources are released. - - In the payload apply path, SPI queries happen inside the trigger, inside another SPI-driven C function, inside a loop. If any intermediate SPI tuptable or relation is not freed, it can “leak” out of the trigger scope and be reported when the outer statement completes. - - That’s why the warning appears specifically when the trigger is executed as part of `cloudsync_payload_apply` but not for direct inserts from psql. - -4. **PostgreSQL 17 reports this more aggressively** - - Earlier versions often tolerated missing `SPI_freetuptable()` calls without warning. PG17 emits the warning when the statement finishes and resources are still registered as open. - -## Why direct INSERTs from psql didn’t warn -The smoke test included a manual `INSERT INTO cloudsync_changes ...`, and it never produced the warning.

- Avoid JSON/text conversions; the SRF should fetch the base-table `Datum` and encode directly. - - Compute `col_value` for a given row using: - - PK decode predicate to locate the row. - - Column `Datum` from SPI tuple (or a helper function returning `Datum`). -- PG payload encode path: - - Treat `col_value` as already-encoded bytes; pass through without decoding. - - Ensure `pgvalues_from_args` preserves `bytea` and `pk_encode` does not re-encode it (it should encode the container row, not the inner value bytes). -

- Wrap the `Datum` into a `pgvalue_t` via `pgvalue_create`, then call `pk_encode` with `argc=1` and `is_prikey=false`. - - Allocate a `bytea` with `VARHDRSZ + encoded_len` and copy the encoded bytes; return the `bytea`. -

-**Moved sql_sqlite.c:** -- `src/sql_sqlite.c` → `src/sqlite/sql_sqlite.c` -- Updated include path from `#include "sql.h"` to `#include "../sql.h"` -- Updated Makefile COV_FILES filter to use new path -- `src/sql.h` remains in shared code (declares SQL constants interface) -- Build verified successful, all tests pass - -The SQL constants are now properly organized: -- `src/sql.h` - Interface (declares extern constants) -- `src/sqlite/sql_sqlite.c` - SQLite implementation (defines constants) -- Future: `src/postgresql/sql_postgresql.c` can provide PostgreSQL-specific SQL - -### [2025-12-17] PostgreSQL Database Implementation Complete ✅ - -**Implemented src/postgresql/database_postgresql.c:** - -Created a comprehensive PostgreSQL implementation of the database abstraction layer (1440 lines): - -**Architecture:** -- Uses PostgreSQL Server Programming Interface (SPI) API -- Implements deferred prepared statement pattern (prepare on first step after all bindings) -- Converts SQLite-style `?` placeholders to PostgreSQL-style `$1, $2, ...` -- Uses `pg_stmt_wrapper_t` struct to buffer parameters before execution -- Proper error handling with PostgreSQL PG_TRY/CATCH blocks -- Memory management using PostgreSQL's palloc/pfree - -**Implemented Functions:** -- **General**: `database_exec()`, `database_exec_callback()`, `database_write()` -- **Select helpers**: `database_select_int()`, `database_select_text()`, `database_select_blob()`, `database_select_blob_2int()` -- **Status**: `database_errcode()`, `database_errmsg()`, `database_in_transaction()`, `database_table_exists()`, `database_trigger_exists()` -- **Schema info**: `database_count_pk()`, `database_count_nonpk()`, `database_count_int_pk()`, `database_count_notnull_without_default()` -- **Metadata**: `database_create_metatable()` -- **Schema versioning**: `database_schema_version()`, `database_schema_hash()`, `database_check_schema_hash()`, `database_update_schema_hash()` -- **Prepared statements (VM)**: `database_prepare()`, `databasevm_step()`, `databasevm_finalize()`, `databasevm_reset()`, `databasevm_clear_bindings()` -- **Binding**: `databasevm_bind_int()`, `databasevm_bind_double()`, `databasevm_bind_text()`, `databasevm_bind_blob()`, `databasevm_bind_null()`, `databasevm_bind_value()` -- **Column access**: `database_column_int()`, `database_column_double()`, `database_column_text()`, `database_column_blob()`, `database_column_value()`, `database_column_bytes()`, `database_column_type()` -- **Value access**: `database_value_int()`, `database_value_double()`, `database_value_text()`, `database_value_blob()`, `database_value_bytes()`, `database_value_type()`, `database_value_dup()`, `database_value_free()` -- **Primary keys**: `database_pk_rowid()`, `database_pk_names()` -- **Savepoints**: `database_begin_savepoint()`, `database_commit_savepoint()`, `database_rollback_savepoint()` -- **Memory**: `dbmem_alloc()`, `dbmem_zeroalloc()`, `dbmem_realloc()`, `dbmem_mprintf()`, `dbmem_vmprintf()`, `dbmem_free()`, `dbmem_size()` -- **Result functions**: `database_result_*()` (placeholder implementations with elog(WARNING)) -- **SQL utilities**: `sql_build_drop_table()`, `sql_escape_name()` - -**Trigger Functions (Placeholder):** -- `database_create_insert_trigger()` -- `database_create_update_trigger_gos()` -- `database_create_update_trigger()` -- `database_create_delete_trigger_gos()` -- `database_create_delete_trigger()` -- `database_create_triggers()` -- `database_delete_triggers()` - -All trigger functions currently use `elog(WARNING, "not yet implemented for PostgreSQL")` and return DBRES_OK. Full implementation requires creating PL/pgSQL trigger functions. - -**Key Technical Details:** -- Uses PostgreSQL information_schema for schema introspection -- CommandCounterIncrement() and snapshot management for read-after-write consistency -- BeginInternalSubTransaction() for savepoint support -- Deferred SPI_prepare pattern to handle dynamic parameter types -- Proper Datum type conversion between C types and PostgreSQL types - -**Implementation Source:** -- Based on reference implementation from `/Users/andrea/Documents/GitHub/SQLiteAI/sqlite-sync-v2.1/postgresql/src/pg_adapter.c` -- Follows same structure and coding style as `src/sqlite/database_sqlite.c` -- Maintains same MARK comments and function organization - -**Status:** -- ✅ All database abstraction API functions implemented -- ✅ Proper error handling and memory management -- ✅ Schema introspection and versioning -- ⏳ Trigger functions need full PL/pgSQL implementation -- ⏳ Needs compilation testing with PostgreSQL headers -- ⏳ Needs integration testing with cloudsync core - -### [2025-12-18] Docker Setup Complete ✅ - -**Created Docker Development Environment:** - -Implemented complete Docker setup for PostgreSQL development and testing: - -**Standalone PostgreSQL Setup:** -- `docker/postgresql/Dockerfile` - Custom PostgreSQL 16 image with CloudSync extension support -- `docker/postgresql/docker-compose.yml` - Orchestration with PostgreSQL and optional pgAdmin -- `docker/postgresql/init.sql` - CloudSync metadata tables initialization -- `docker/postgresql/cloudsync.control` - PostgreSQL extension control file - -**Supabase Integration:** -- `docker/supabase/docker-compose.yml` - Override configuration for official Supabase stack -- Uses custom image `sqliteai/sqlite-sync-pg:latest` with CloudSync extension -- Integrates with all Supabase services (auth, realtime, storage, etc.) - -**Documentation:** -- `docker/README.md` - Comprehensive guide covering: - - Quick start for standalone PostgreSQL - - Supabase integration setup - - Development workflow - - Building and installing extension - - Troubleshooting common issues - - Environment variables and customization - -**Key Features:** -- Volume mounting for live source code development -- Persistent database storage -- Health checks for container orchestration -- Optional pgAdmin web UI for database management -- Support for both standalone and Supabase deployments - -**Next Steps:** -- Build the Docker image: `docker build -t sqliteai/sqlite-sync-pg:latest` -- Implement PostgreSQL extension entry point and SQL function bindings -- Create Makefile targets for PostgreSQL compilation -- Add PostgreSQL-specific trigger implementations - -## Phase 8: PostgreSQL Extension SQL Functions ✅ (Mostly Complete) - -**Goal:** Implement PostgreSQL extension entry point (`cloudsync_postgresql.c`) that exposes all CloudSync SQL functions. - -### Files Created - -- ✅ `src/postgresql/cloudsync_postgresql.c` - PostgreSQL extension implementation (19/27 functions fully implemented) -- ✅ `src/postgresql/cloudsync--1.0.sql` - SQL installation script - -### SQL Functions to Implement - -**Public Functions:** -- ✅ `cloudsync_version()` - Returns extension version -- ✅ `cloudsync_init(table_name, [algo], [skip_int_pk_check])` - Initialize table for sync (1-3 arg variants) -- ✅ `cloudsync_enable(table_name)` - Enable sync for table -- ✅ `cloudsync_disable(table_name)` - Disable sync for table -- ✅ `cloudsync_is_enabled(table_name)` - Check if table is sync-enabled -- ✅ `cloudsync_cleanup(table_name)` - Cleanup orphaned metadata -- ✅ `cloudsync_terminate()` - Terminate CloudSync -- ✅ `cloudsync_set(key, value)` - Set global setting -- ✅ `cloudsync_set_table(table, key, value)` - Set table setting -- ✅ `cloudsync_set_column(table, column, key, value)` - Set column setting -- ✅ `cloudsync_siteid()` - Get site identifier (UUID) -- ✅ `cloudsync_db_version()` - Get current database version -- ✅ `cloudsync_db_version_next([version])` - Get next version -- ✅ `cloudsync_begin_alter(table)` - Begin schema alteration -- ✅ `cloudsync_commit_alter(table)` - Commit schema alteration -- ✅ `cloudsync_uuid()` - Generate UUID -- ⚠️ `cloudsync_payload_encode()` - Aggregate: encode changes to payload (partial - needs variadic args) -- ✅ `cloudsync_payload_decode(payload)` - Apply payload to database -- ✅ `cloudsync_payload_apply(payload)` - Alias for decode - -**Private/Internal Functions:** -- ✅ `cloudsync_is_sync(table)` - Check if table has metadata -- ✅ `cloudsync_insert(table, pk_values...)` - Internal insert handler (uses pgvalue_t from anyarray) -- ⚠️ `cloudsync_update(table, pk, new_value)` - Aggregate: track updates (stub - complex aggregate) -- ✅ `cloudsync_seq()` - Get sequence number -- ✅ `cloudsync_pk_encode(pk_values...)` - Encode primary key (uses pgvalue_t from anyarray) -- ⚠️ `cloudsync_pk_decode(encoded_pk, index)` - Decode primary key component (stub - needs callback) - -**Note:** Standardize PostgreSQL `dbvalue_t` as `pgvalue_t` (`Datum + Oid + typmod + collation + isnull + detoasted flag`) so value/type helpers can resolve type/length/ownership without relying on `fcinfo` lifetime; payload/PK helpers should consume arrays of these wrappers (built from `PG_FUNCTION_ARGS` and SPI tuples). Implemented in `src/postgresql/pgvalue.c/.h` and used by value/column accessors and PK/payload builders. - -### Implementation Strategy - -1. **Create Extension Entry Point** (`_PG_init`) - ```c - void _PG_init(void); - void _PG_fini(void); - ``` - -2. **Register Functions** using PostgreSQL's function manager - ```c - PG_FUNCTION_INFO_V1(cloudsync_version); - Datum cloudsync_version(PG_FUNCTION_ARGS); - ``` - -3. **Context Management** - - Create `cloudsync_postgresql_context` structure - - Store in PostgreSQL's transaction-local storage - - Cleanup on transaction end - -4. **Aggregate Functions** - - Implement state transition and finalization functions - - Use PostgreSQL's aggregate framework - -5. **SQL Installation Script** - - Create `cloudsync--1.0.sql` with `CREATE FUNCTION` statements - - Define function signatures and link to C implementations - -### Testing Approach - -1. Build extension in Docker container -2. Load extension: `CREATE EXTENSION cloudsync;` -3. Test each function individually -4. Verify behavior matches SQLite implementation -5. Run integration tests with CRDT core logic - -### Reference Implementation - -- Study: `src/sqlite/cloudsync_sqlite.c` (SQLite version) -- Adapt to PostgreSQL SPI and function framework -- Reuse core logic from `src/cloudsync.c` (database-agnostic) - -## Progress Log (Continued) - -### [2025-12-19] Phase 8 Implementation - Major Progress ✅ - -Implemented most CloudSync SQL functions for PostgreSQL extension: - -**Changes Made:** - -1. **Removed unnecessary helper function:** - - Deleted `dbsync_set_error()` helper function - - Replaced with direct `ereport(ERROR, (errmsg(...)))` calls - - PostgreSQL's `errmsg()` already supports format strings, unlike SQLite - -2. **Fixed cloudsync_init API:** - - **CRITICAL FIX**: Previous implementation used wrong signature `(site_id, url, key)` - - Corrected to match SQLite API: `(table_name, [algo], [skip_int_pk_check])` - - Created `cloudsync_init_internal()` helper that replicates `dbsync_init` logic from SQLite - - Implemented single variadic `cloudsync_init()` function supporting 1-3 arguments with defaults - - Updated SQL installation script to create 3 function overloads pointing to same C function - - Returns site_id as TEXT (matches SQLite behavior) - -3. **Implemented 19 of 27 SQL functions:** - - ✅ All public configuration functions (enable, disable, set, set_table, set_column) - - ✅ All schema alteration functions (begin_alter, commit_alter) - - ✅ All version/metadata functions (version, siteid, uuid, db_version, db_version_next, seq) - - ✅ Cleanup and termination functions - - ✅ Payload decode/apply functions - - ✅ Private is_sync function - -4. **Partially implemented complex aggregate functions:** - - ⚠️ `cloudsync_payload_encode_transfn/finalfn` - Basic structure in place, needs variadic arg conversion - - ⚠️ `cloudsync_update_transfn/finalfn` - Stubs created - - ⚠️ `cloudsync_insert` - Stub (requires variadic PK handling) - - ⚠️ `cloudsync_pk_encode/decode` - Stubs (require anyarray to dbvalue_t conversion) - -**Architecture Decisions:** - -- All functions use SPI_connect()/SPI_finish() pattern with PG_TRY/CATCH for proper error handling -- Context management uses global `pg_cloudsync_context` (per backend) -- Error reporting uses PostgreSQL's native `ereport()` with appropriate error codes -- Memory management uses PostgreSQL's palloc/pfree in aggregate contexts -- Follows same function organization and MARK comments as SQLite version - -**Status:** -- ✅ 19/27 functions fully implemented and ready for testing -- ⚠️ 5 functions have stubs requiring PostgreSQL-specific variadic argument handling -- ⚠️ 3 aggregate functions need completion (update transfn/finalfn, payload_encode transfn) -- ⏳ Needs compilation testing with PostgreSQL headers -- ⏳ Needs integration testing with cloudsync core - -## SQL Parity Review (PostgreSQL vs SQLite) - -Findings comparing `src/postgresql/sql_postgresql.c` to `src/sqlite/sql_sqlite.c`: -- Missing full DB version query composition: SQLite builds a UNION of all `*_cloudsync` tables plus `pre_alter_dbversion`; PostgreSQL has a two-step builder but no `pre_alter_dbversion` or execution glue. -- `SQL_DATA_VERSION`/`SQL_SCHEMA_VERSION` are TODO placeholders (`SELECT 1`), not equivalents to SQLite pragmas. -- `SQL_SITEID_GETSET_ROWID_BY_SITEID` returns `ctid` and lacks the upsert/rowid semantics of SQLite’s insert-or-update/RETURNING rowid. -- Row selection/build helpers (`*_BY_ROWID`, `*_BY_PK`) are reduced placeholders using `ctid` or simple string_agg; they do not mirror SQLite’s dynamic SQL with ordered PK clauses and column lists from `pragma_table_info`. -- Write helpers (`INSERT_ROWID_IGNORE`, `UPSERT_ROWID_AND_COL_BY_ROWID`, PK insert/upsert formats) diverge: SQLite uses `rowid` and conflict clauses; PostgreSQL variants use `%s` placeholders without full PK clause/param construction. -- Cloudsync metadata upserts differ: `SQL_CLOUDSYNC_UPSERT_COL_INIT_OR_BUMP_VERSION`/`_RAW_COLVERSION` use `EXCLUDED` logic not matching SQLite’s increment rules; PK tombstone/cleanup helpers are partial. -- Many format strings lack quoting/identifier escaping parity (`%w` behavior) and expect external code to supply WHERE clauses, making them incomplete compared to SQLite’s self-contained templates. - -TODOs to fix `sql_postgresql.c`: -- Recreate DB version query including `pre_alter_dbversion` union and execution wrapper. -- Implement PostgreSQL equivalents for data_version/schema_version. -- Align site_id getters/setters to return stable identifiers (no `ctid`) and mirror SQLite upsert-return semantics. -- Port the dynamic SQL builders for select/delete/insert/upsert by PK/non-PK to generate complete statements (including ordered PK clauses and binds), respecting identifier quoting. -- Align cloudsync metadata updates/upserts/tombstoning to SQLite logic (version bump rules, ON CONFLICT behavior, seq/db_version handling). -- Ensure all format strings include proper identifier quoting and do not rely on external WHERE fragments unless explicitly designed that way. - -**Next Steps:** -- Implement PostgreSQL anyarray handling for variadic functions (pk_encode, pk_decode, insert) -- Complete aggregate function implementations (update, payload_encode) -- Add PostgreSQL-specific Makefile targets -- Build and test extension in Docker container - -### [2025-12-19] Implemented cloudsync_insert ✅ - -Completed the `cloudsync_insert` function using the new `pgvalue_t` infrastructure: - -**Implementation Details:** - -1. **Signature**: `cloudsync_insert(table_name text, VARIADIC pk_values anyarray)` - - Uses PostgreSQL's VARIADIC to accept variable number of PK values - - Converts anyarray to `pgvalue_t **` using `pgvalues_from_array()` - -2. **Key Features**: - - Validates table exists and PK count matches expected - - Encodes PK values using `pk_encode_prikey()` with stack buffer (1024 bytes) - - Handles sentinel records for PK-only tables - - Marks all non-PK columns as inserted in metadata - - Proper memory management: frees `pgvalue_t` wrappers after use - -3. **Error Handling**: - - Comprehensive cleanup in both success and error paths - - Uses `goto cleanup` pattern for centralized resource management - - Wraps in `PG_TRY/CATCH` for PostgreSQL exception safety - - Cleans up resources before re-throwing exceptions - -4. **Follows SQLite Logic**: - - Matches `dbsync_insert` behavior from `src/sqlite/cloudsync_sqlite.c` - - Same sequence: encode PK → get next version → check existence → mark metadata - - Handles both new inserts and updates to previously deleted rows - -**Status**: -- ✅ `cloudsync_insert` fully implemented -- ✅ `cloudsync_pk_encode` already implemented (was done in previous work) -- ✅ `cloudsync_payload_encode_transfn` already implemented (uses pgvalues_from_args) -- ⚠️ `cloudsync_pk_decode` still needs callback implementation -- ⚠️ `cloudsync_update_*` aggregate functions still need implementation - -**Function Count Update**: 21/27 functions (78%) now fully implemented - -### [2025-12-19] PostgreSQL Makefile Targets Complete ✅ - -Implemented comprehensive Makefile infrastructure for PostgreSQL extension development: - -**Files Created/Modified:** - -1. **`docker/Makefile.postgresql`** - New PostgreSQL-specific Makefile with all build targets: - - Build targets: `postgres-check`, `postgres-build`, `postgres-install`, `postgres-clean`, `postgres-test` -

-**Key Features:** - -- **Single Entry Point**: All PostgreSQL targets accessible via `make postgres-*` from root -- **Pre-built Image**: `make postgres-docker-build` creates image with extension pre-installed -- **Fast Development**: `make postgres-dev-rebuild` rebuilds extension in <5 seconds without restarting container -- **Clean Separation**: PostgreSQL logic isolated in `docker/Makefile.postgresql`, included by root Makefile -- **Docker-First**: Optimized for containerized development with source mounting - -**Usage Examples:** - -```bash -# Build Docker image with CloudSync extension -make postgres-docker-build - -# Start PostgreSQL container -make postgres-docker-run - -# Test extension -docker exec -it cloudsync-postgres psql -U postgres -d cloudsync_test \ - -c "CREATE EXTENSION cloudsync; SELECT cloudsync_version();" - -# Make code changes, then quick rebuild -make postgres-dev-rebuild -``` - -**Status:** -- ✅ All Makefile targets implemented and tested -- ✅ Dockerfile optimized for build and development -- ✅ Documentation complete (README + POSTGRESQL.md) -- ⏳ Ready for first build and compilation test -- ⏳ Needs actual PostgreSQL compilation verification - -**Next Steps:** -- Test actual compilation: `make postgres-docker-build` -- Fix any compilation errors -- Test extension loading: `CREATE EXTENSION cloudsync` -- Complete remaining aggregate functions - -### [2025-12-20] PostgreSQL Trigger + SPI Cleanup Work ✅ - -**Trigger functions implemented in `src/postgresql/database_postgresql.c`:** -- `database_create_insert_trigger` implemented with per-table PL/pgSQL function and trigger. -- `database_create_update_trigger_gos`/`database_create_delete_trigger_gos` implemented (BEFORE triggers, raise on update/delete when enabled). -- `database_create_update_trigger` implemented with VALUES list + `cloudsync_update` aggregate call. -- `database_create_delete_trigger` implemented to call `cloudsync_delete`. -- `database_create_triggers` wired to create insert/update/delete triggers based on algo. -- `database_delete_triggers` updated to drop insert/update/delete triggers and their functions. - -**PostgreSQL SQL registration updates:** -- Added `cloudsync_delete` to `src/postgresql/cloudsync--1.0.sql`. - -**Internal function updates:** -- Implemented `cloudsync_delete` C function (mirrors SQLite delete path). -- `cloudsync_insert`/`cloudsync_delete` now lazily load table context when missing. -- Refactored `cloudsync_insert`/`cloudsync_delete` to use `PG_ENSURE_ERROR_CLEANUP` and shared cleanup helper. - -**SPI execution fixes:** -- `databasevm_step` now uses `SPI_is_cursor_plan` before opening a portal to avoid “cannot open INSERT query as cursor”. -- Persistent statements now allocate their memory contexts under `TopMemoryContext`. - -**Error formatting:** -- `cloudsync_set_error` now avoids `snprintf` aliasing when `database_errmsg` points at `data->errmsg`. - -**Smoke test updates:** -- `docker/postgresql/smoke_test.sql` now validates insert/delete metadata, tombstones, and site_id fields. -- Test output uses `\echo` markers for each check. - -**Documentation updates:** -- Added PostgreSQL SPI patterns to `AGENTS.md`. -- Updated Database Abstraction Layer section in `AGENTS.md` to match `database.h`. diff --git a/plans/TODO.md b/plans/TODO.md index 7b5607a..d242187 100644 --- a/plans/TODO.md +++ b/plans/TODO.md @@ -1,79 +1,2 @@ -# SQLite vs PostgreSQL Parity Matrix -

The core CRDT functions are shared by the SQLite and PostgreSQL extensions. Includes support for PostgreSQL-native types (UUID primary keys, composite PKs with mixed types, and automatic type casting). - **Row-Level Security (RLS)**: Sync payloads are now fully compatible with SQLiteCloud and PostgreSQL Row-Level Security policies. Changes are buffered per primary key and flushed as complete rows, so RLS policies can evaluate all columns at once. +- **Block-level LWW for text conflict resolution**: Text columns can now be tracked at block level (lines by default) using Last-Writer-Wins. Concurrent edits to different parts of the same text are preserved after sync. New functions: `cloudsync_set_column()` to write individual blocks and `cloudsync_text_materialize()` to reconstruct the full text. ### Changed @@ -40,6 +41,8 @@ The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/). ``` - **Batch merge replaces column-by-column processing**: During sync, changes to the same row are now applied in a single SQL statement instead of one statement per column.

Previously each winning column was written immediately via a single-column `INSERT ... ON CONFLICT DO UPDATE`. This caused two issues with PostgreSQL RLS: - -1. **Partial-column UPSERT fails INSERT WITH CHECK**: An update to just `title` generates `INSERT INTO docs (id, title) VALUES (...) ON CONFLICT DO UPDATE SET title=...`. PostgreSQL evaluates the INSERT `WITH CHECK` policy *before* checking for conflicts. Missing columns (e.g. `user_id`) default to NULL, so `auth.uid() = user_id` fails. The ON CONFLICT path is never reached. - -2. **Premature flush in SPI**: `database_in_transaction()` always returns true inside PostgreSQL SPI. The old code only updated `last_payload_db_version` inside `if (!in_transaction && db_version_changed)`, so the variable stayed at -1, `db_version_changed` was true on every row, and batches flushed after every single column. - -## Solution - -### Batch merge (`merge_pending_batch`) - -New structs in `cloudsync.c`: - -- `merge_pending_entry` — one buffered column (col_name, col_value via `database_value_dup`, col_version, db_version, site_id, seq) -- `merge_pending_batch` — collects entries for one PK (table, pk, row_exists flag, entries array, statement cache) - -`data->pending_batch` is set to `&batch` (stack-allocated) at the start of `cloudsync_payload_apply`. The INSTEAD OF trigger calls `merge_insert`, which calls `merge_pending_add` instead of `merge_insert_col`. Flush happens at PK/table/db_version boundaries and after the loop. - -### UPDATE vs UPSERT (`row_exists` flag) - -`merge_insert` sets `batch->row_exists = (local_cl != 0)` on the first winning column. At flush time `merge_flush_pending` selects: - -- `row_exists=true` -> `sql_build_update_pk_and_multi_cols` -> `UPDATE docs SET title=? WHERE id=?` -- `row_exists=false` -> `sql_build_upsert_pk_and_multi_cols` -> `INSERT ... ON CONFLICT DO UPDATE` - -Both SQLite and PostgreSQL implement `sql_build_update_pk_and_multi_cols` as a proper UPDATE statement. This is required for SQLiteCloud (which uses the SQLite extension but enforces RLS). - -**Example**: DB A and DB B both have row `id='doc1'` with `user_id='alice'`, `title='Hello'`. Alice updates `title='World'` on A. The payload applied to B contains only `(id, title)`: - -- **UPSERT** (wrong for RLS): `INSERT INTO docs ("id","title") VALUES (?,?) ON CONFLICT DO UPDATE SET "title"=EXCLUDED."title"` — fails INSERT `WITH CHECK` because `user_id` is NULL in the proposed row. -- **UPDATE** (correct): `UPDATE "docs" SET "title"=?2 WHERE "id"=?1` — skips INSERT `WITH CHECK` entirely; the UPDATE `USING` policy checks the existing row which has the correct `user_id`. - -In plain SQLite (no RLS) both produce the same result. The distinction only matters when RLS is enforced (SQLiteCloud, PostgreSQL). - -### Statement cache - -`merge_pending_batch` caches the last prepared statement (`cached_vm`) along with the column combination and `row_exists` flag that produced it. On each flush, `merge_flush_pending` compares the current column names, count, and `row_exists` against the cache: - -- **Cache hit**: `dbvm_reset` + rebind (skip SQL build and `databasevm_prepare`) -- **Cache miss**: finalize old cached statement, build new SQL, prepare, and update cache - -This recovers the precompiled-statement advantage of the old single-column path. In a typical payload where consecutive PKs change the same columns, the cache hit rate is high. - -The cached statement is finalized once at the end of `cloudsync_payload_apply`, not on every flush. - -### `last_payload_db_version` fix - -Moved the update outside the savepoint block so it executes unconditionally: - -```c -if (db_version_changed) { - last_payload_db_version = decoded_context.db_version; -} -``` - -Previously this was inside `if (!in_transaction && db_version_changed)`, which never ran in SPI. - -## Savepoint Architecture - -### Two-level savepoint design - -`cloudsync_payload_apply` uses two layers of savepoints that serve different purposes: - -| Layer | Where | Purpose | -|-------|-------|---------| -| **Outer** (per-db_version) | `cloudsync_payload_apply` loop | Transaction grouping + commit hook trigger (SQLite only) | -| **Inner** (per-PK) | `merge_flush_pending` | RLS error isolation + executor resource cleanup | - -### Outer savepoints: per-db_version in `cloudsync_payload_apply` - -```c -if (!in_savepoint && db_version_changed && !database_in_transaction(data)) { - database_begin_savepoint(data, "cloudsync_payload_apply"); - in_savepoint = true; -} -``` - -These savepoints group rows with the same source `db_version` into one transaction.

This is correct because: -1. PostgreSQL has no equivalent commit hook on subtransaction release -2. The SPI transaction from `SPI_connect` already provides transaction context -3. The inner per-PK savepoint handles the RLS isolation PostgreSQL needs - -**Why a single outer savepoint doesn't work**: We tested replacing per-db_version savepoints with a single savepoint wrapping the entire loop. This broke the `(db_version, seq)` uniqueness invariant in SQLite because the commit hook never fired mid-apply — `data->db_version` never advanced and `seq` never reset. - -### Inner savepoints: per-PK in `merge_flush_pending` - -```c -flush_savepoint = (database_begin_savepoint(data, "merge_flush") == DBRES_OK); -// ... database operations ... -cleanup: - if (flush_savepoint) { - if (rc == DBRES_OK) database_commit_savepoint(data, "merge_flush"); - else database_rollback_savepoint(data, "merge_flush"); - } -``` - -Wraps each PK's flush in a savepoint. On failure (e.g. RLS denial), `database_rollback_savepoint` calls `RollbackAndReleaseCurrentSubTransaction()` in PostgreSQL, which properly releases all executor resources (open relations, snapshots, plan cache) acquired during the failed statement. This eliminates the "resource was not closed" warnings that `SPI_finish` previously emitted. - -In SQLite, when the outer per-db_version savepoint is active, these become harmless nested savepoints. - -### Platform behavior summary - -| Environment | Outer savepoint | Inner savepoint | Effect | -|---|---|---|---| -| **PostgreSQL SPI** | Dead code (`in_transaction` always true) | Active — RLS error isolation + resource cleanup | Only inner savepoint runs | -| **SQLite client** | Active — groups writes, triggers commit hook | Active — nested inside outer, harmless | Both run; outer provides transaction grouping | -| **SQLiteCloud** | Active — groups writes, triggers commit hook | Active — RLS error isolation | Both run; each serves its purpose | - -## SPI and Memory Management - -### Nested SPI levels - -`pg_cloudsync_payload_apply` calls `SPI_connect` (level 1). Inside the loop, `databasevm_step` executes `INSERT INTO cloudsync_changes`, which fires the INSTEAD OF trigger. The trigger calls `SPI_connect` (level 2), runs `merge_insert` / `merge_pending_add`, then `SPI_finish` back to level 1. The deferred `merge_flush_pending` runs at level 1. - -### `database_in_transaction()` in SPI - -Always returns true in SPI context (`IsTransactionState()`). This makes the per-db_version savepoints dead code in PostgreSQL and is why `last_payload_db_version` must be updated unconditionally. - -### Error handling in SPI - -When RLS denies a write, PostgreSQL raises an error inside SPI. The inner per-PK savepoint in `merge_flush_pending` catches this: `RollbackAndReleaseCurrentSubTransaction()` properly releases all executor resources. Without the savepoint, `databasevm_step`'s `PG_CATCH` + `FlushErrorState()` would clear the error stack but leave executor resources orphaned, causing `SPI_finish` to emit "resource was not closed" warnings. - -### Batch cleanup paths - -`batch.entries` is heap-allocated via `cloudsync_memory_realloc` and reused across flushes. Each entry's `col_value` (from `database_value_dup`) is freed by `merge_pending_free_entries` on every flush. The entries array, `cached_vm`, and `cached_col_names` are freed once at the end of `cloudsync_payload_apply`. Error paths (`goto cleanup`, early returns) must free all three and call `merge_pending_free_entries` to avoid leaking `col_value` copies. - -## Batch Apply: Pros and Cons - -The batch path is used for all platforms (SQLite client, SQLiteCloud, PostgreSQL), not just when RLS is active. - -**Pros (even without RLS)**: -- Fewer SQL executions: N winning columns per PK become 1 statement instead of N. Each `databasevm_step` involves B-tree lookup, page modification, WAL write. -- Atomicity per PK: all columns for a PK succeed or fail together. - -**Cons**: -- Dynamic SQL per unique column combination (mitigated by the statement cache). -- Memory overhead: `database_value_dup` copies each column value into the buffer. -- Code complexity: batching structs, flush logic, cleanup paths. - -**Why not maintain two paths**: SQLiteCloud uses the SQLite extension with RLS, so the batch path (UPDATE vs UPSERT selection, per-PK savepoints) is required there. Maintaining a separate single-column path for plain SQLite clients would double the code with marginal benefit. - -## Files Changed - -| File | Change | -|------|--------| -| `src/cloudsync.c` | Batch merge structs with statement cache (`cached_vm`, `cached_col_names`), `merge_pending_add`, `merge_flush_pending` (with per-PK savepoint), `merge_pending_free_entries`; `pending_batch` field on context; `row_exists` propagation in `merge_insert`; batch mode in `merge_sentinel_only_insert`; `last_payload_db_version` fix; removed `payload_apply_callback` | -| `src/cloudsync.h` | Removed `CLOUDSYNC_PAYLOAD_APPLY_STEPS` enum | -| `src/database.h` | Added `sql_build_upsert_pk_and_multi_cols`, `sql_build_update_pk_and_multi_cols`; removed callback typedefs | -| `src/sqlite/database_sqlite.c` | Implemented `sql_build_upsert_pk_and_multi_cols` (dynamic SQL); `sql_build_update_pk_and_multi_cols` (delegates to upsert); removed callback functions | -| `src/postgresql/database_postgresql.c` | Implemented `sql_build_update_pk_and_multi_cols` (meta-query against `pg_catalog` generating typed UPDATE) | -| `test/unit.c` | Removed callback code and `do_test_andrea` debug function (fixed 288048-byte memory leak) | -| `test/postgresql/27_rls_batch_merge.sql` | Tests 1-3 (superuser) + Tests 4-6 (authenticated-role RLS enforcement) | -| `docs/postgresql/RLS.md` | Documented INSERT vs UPDATE paths and partial-column RLS interaction | - -## TODO - - - update documentation: RLS.md, README.md and the https://github.com/sqlitecloud/docs repo diff --git a/plans/TODO.md b/plans/TODO.md deleted file mode 100644 index d242187..0000000 --- a/plans/TODO.md +++ /dev/null @@ -1,2 +0,0 @@ -- I need to call cloudsync_update_schema_hash to update the last schema hash when upgrading the library from the 0.8.* version -- Fix cloudsync_begin_alter and cloudsync_commit_alter for PostgreSQL, and we could call them automatically with a trigger on ALTER TABLE \ No newline at end of file From 18909a2f80d952ea6c711d2b935087bcdc48fb43 Mon Sep 17 00:00:00 2001 From: Andrea Donetti Date: Wed, 18 Mar 2026 23:02:32 -0600 Subject: [PATCH 64/86] test: improved stress test command --- .../commands/stress-test-sync-sqlitecloud.md | 53 +++++++++++++------ 1 file changed, 37 insertions(+), 16 deletions(-) diff --git a/.claude/commands/stress-test-sync-sqlitecloud.md b/.claude/commands/stress-test-sync-sqlitecloud.md index 4bb41fa..22102cb 100644 --- a/.claude/commands/stress-test-sync-sqlitecloud.md +++ b/.claude/commands/stress-test-sync-sqlitecloud.md @@ -106,11 +106,16 @@ Create a bash script at `/tmp/stress_test_concurrent.sh` that: 2. **Defines a worker function** that runs in a subshell for each database: - Each worker logs all output to `/tmp/sync_concurrent_.log` - Each iteration does: - a. **DELETE all rows** → `cloudsync_network_sync(100, 10)` - b. **INSERT rows** (in a single BEGIN/COMMIT transaction) → `cloudsync_network_sync(100, 10)` - c. **UPDATE all rows** → `cloudsync_network_sync(100, 10)` - - Each session must: `.load` the extension, call `cloudsync_network_init()`, `cloudsync_network_set_token()` (if RLS), do the work, call `cloudsync_terminate()` - - Include labeled output lines like `[DB][iter ] deleted/inserted/updated, count=` for grep-ability + a. **UPDATE all/some rows** (e.g., `UPDATE

Build the custom Supabase Postgres image + +The project includes `docker/postgresql/Dockerfile.supabase` which builds CloudSync into the Supabase Postgres base image.
