It seems, nouveau isn't shutting down properly by our dev/run script. Needs additional investigation.

[big-r81]

Update:

A file handle to dev/log/nouveau.log is open too after running the test. The file can't be deleted for example.

[big-r81]

Fixed the open file handle issue by commit b7ca600.

Commands:

.\make.cmd
...
==> rel (compile)
==> couchdb (compile)
        1 file(s) copied.

The changes look good based on the diff. I didn't run it on Windows. It looks like you did and it worked, so I think that's good enough.

[big-r81]

Thanks Nick, if you have time, you can test it before merging.

@big-r81 since you insisted, as rightly you should have :-) I have tested the PR on the windows CI machine (on my own clone of couchdb).

Thanks keeping it updated
