Process

The process to create this sync is the following:

• Create a new branch off of the LTS branch for syncs up to current date, e.g. lts-backports/sync-230423
• For each merged pull request that needs to be merged into LTS:
  • Cherry pick ranges of commits (you can use the github commits page of the PR to copy the oldest and newest commit hash): e.g. git cherry-pick "fdc342d15a2908f4b72f437aeb05165eba098920^..f3874fea755ba3c6bdb28fcf33d870c4dbad451e" (see this stackoverflow answer for details)
  • Fix any pending conflicts (using the Conflict editor of vscode seems to be the easiest option.
  • Confirm the cherry pick operation with git cherry-pick --continue
  • Repeat for the next pull request
• Push the sync branch and create a pull request to the LTS branch
