Make PR in related repos bumping versions when a deploy is performed

[soywiz]

For example if we release a new version of Klock, the bot should make a PR to korio bumping version in its gradle.properties so people in the team can merge it

[emign]

did you already start this?

[soywiz]

Not started yet

[emign]

do you want it to be in GitHub actions?

[soywiz]

yeah, I think that would be the best place

[emign]

To prevent an intransparent web of bots updating all libs on their own I suggest a korlibs version repository which just holds all the version numbers. The subrepos then get an action when they have a new deploy to update the central version number repository.
When someone merges the PR in the versioning repository it can fan out to creating PRs on the subrepos.

Any complains or suggestions?

[soywiz]

Cool. Great idea

Please check for missing modules/repos https://github.com/korlibs/korlibs-versions

[emign]

Please check. https://github.com/korlibs/klock/blob/versioningWorkflow/.github/workflows/VERSIONSYNCTEST.yml
Failing atm due to missing authorization rights. Could issue a personal access token, but that would be bound to my account. Need another way or create a bot account on GitHub with according privileges to make PRs

Okay. Finally. We needed to add korgebot to write access members for korlibs-versions. Didn't think about that. We dont fork but rather create PRs on korlibs-versions

This workflow now adds PRs whenever klock changes. We would need to adapt this for every sub library and add it to the deploy workflow (since GHA workflows cannot trigger other workflows on their own as I recall). We should review this workflow before we proliferate it though.

Then we should leave it running for some days/deploys to see if any weird things happen on korlibs-versions. After that we could think about using it as a version-number-server

[soywiz]

I think that bot should directly write to the korlibs-versions repo then that repo fanout to the right repos with PRs. If we make a PR to korlibs-versions that would delay the other PRs

[emign]

We could auto merge the PRs. Will that work?

EDIT: There wouldn't be much of a difference if the PRs are auto merged vs direct writing. Ill change the bot to directly commit

[emign]

The bot now commits directly to the master of korlibs-versions
