Hard Crash on GitHub Sync

I know you’ve been putting some time into hardening the Git sync process, @adam, so it’s possible you can just ignore this post.

Just had PSU 3.2 crash hard - had to restart the Azure app service to get it back. The last thing in the log is this:

[08:00:09 DBG] Git has remote. Starting push

As I said, with any luck this is something you’ve already fixed in 3.3 with the work you’ve been doing on the Git sync process.

Cheers!

While I haven’t see this exactly, in v3.3, you’ll be able to use an external git client rather than using the git library we have been using. When this is the case, an external process (git.exe) will be started that will run the git comments so any crashes of that process won’t affect the PSU service.

It also means that we are using the official, supported git client rather than libgit2, which while very popular, isn’t the same git client used by tools like VS Code, ect. It also means that we get more functionality and configuration options not currently available in PSU. One example is SSH support so you won’t need to necessarily pass any credentials to the git client after that’s been configured on the PSU host machine.
