Updating packed-refs fails on Windows if `mmap`-ed (i.e. file size is over 32KiB) about gitoxide

I have just released a patch for gix-ref and you are welcome to try it. In my CI testing, the patch did resolve the issue described here that was reproduced beforehand.

The error no longer occurs for me after upgrading to gix-ref 0.39.1. Thanks @Byron and @yuja for such a quick turnaround!

[Byron]

Thanks for reporting!

A test for this is definitely missing (as in: delete while packed refs is memmapped), and I will rectify this along with a 'fix' (which probably has to be to simply not mmap on Windows).

Yeah. There would be no reasonable workaround if mmaped file can't be deleted. External git process should be able to update packed-refs while it is mmapped by gix.

Thanks for the quick fix!

@jennings, can you test this with your repo?

Please keep me posted on how it goes (despite this issue being auto-closed by the PR). I am pretty optimistic sure that it works now and hope it will work for you, too.
