[bitbake][dunfell][1.46][PATCH 1/8] lib/ui/taskexp: Validate gi import

[Steve Sakoman]

From: David Khouya <dakhouya@gmail.com>

When running bitbake -g -u taskexp without having gi python module or
and invalid gtk version, bitbake fails with a stack trace.

In case of import or version error, bitbake should exit with an error
message instead of a stack trace.

[bitbake][dunfell][1.46][PATCH 5/8] fetch2: Change git fetcher not to destroy old references

[Steve Sakoman]

From: Richard Purdie <richard.purdie@linuxfoundation.org>

It looks like we're about to see a lot of changes in branch names in repos. If
we have the prune option here, those old names are lost, the changes propagate
to our source mirrors and our old releases break.

We have the force option so any replaced references should be replaced, its only
orphaned branches which will now be preserved.

I believe this behaviour will cause us fewer problems given the changes that
look likely to happen.

[bitbake][dunfell][1.46][PATCH 7/8] server/process: Fix a rare lockfile race

[Steve Sakoman]

From: Richard Purdie <richard.purdie@linuxfoundation.org>

We're seeing rare occasional races on the autobuilder as if two server
processes have the lockfile at the same time. We need to be extremely
careful this does not happen.

I think there is a potential race in this shutdown code since we delete
the lockfile, then call unlockfile() which also tries to delete it.

This means we may remove a lock file now held by another process if we're
unlucky. Since unlockfile removes the lockfile when it can, just rely on
that and remove any possible race window.

An example cooker-deamonlog:

where it looks like there are two server processes running which should not be.
In that build there was a process left sitting in memory with its bitbake.sock file
missing but holding the lock (not sure why it wouldn't timeout/exit).

[bitbake][dunfell][1.46][PATCH 8/8] server/process: Ensure UI-less servers don't sit in infinite loops

[Steve Sakoman]

From: Richard Purdie <richard.purdie@linuxfoundation.org>

If server startup is broken for some reason (e.g. lockfile issues)
and no UI connection is made, the server will just sit inifinitely
waiting.

Add a timeout upon startup in the non-memory resident case so that
such infinite waits are avoided. In the memory resident case, the
server wouldn't have shut down in the first place or will timeout
according to configuration.

Since any race may mean the socket file is no longer present, ensure
the unlink doesn't fault upon exit, thus ensuring any hashequiv or
PRServ is removed from memory, allowing all processes to exit
cleanly in such scenarios.
