I think you can download pre-released builds from:
https://cygwin.com/snapshots/
As mentioned already, the fix here is not actually support of AF_UNIX
sockets natively. My understanding is that they are implemented over
loopback TCP in cygwin, but the fix allows native AF_UNIX sockets to be
handled (eg deleted) as regular files through regular cygwin commands.

Hi all
Does anyone know the status of these fixes ?
I saw an announcement for cygwin-3.2.0-0.1 that seemed to contain some
AF_UNIX-related fixes but I fail to find out where that distribution exists
(if it is supposed to be publicly accessible?), but I tried out the
2021-03-01 snapshot and perhaps they are similar ?
We bumped into some AF_UNIX-related issues when trying the 2021-03-01
-snapshot though. It might be some flaws in our code base but the same code
works in quite a few Linux-distros
We're more than willing to help out with testing this and/or trying to
narrow down any possible cygwin issues, but first we'd be glad if someone
could give us some kind of status report of this (so no one is doing any
unnecessary work)
Best regards,
Kristian
p.s.
I tried to build the topic/af_unix -branch according to the FAQ, but
there was some issues
d.s.
Hi Ken, Corinna
Sorry for the delay in responding. I have just tested the fix and it
works great. Thank you very much for looking into it.
When do you think it would be available in a form that regular users
would be able to update/install?
Corinna decides when to make a new Cygwin release. My best guess is
"pretty soon".
Also, one observation FYI, is that the "ls -l" command on Unix
normally indicates sockets with an "s" as the first character of the
output: eg
srwxr-xr-x 1 Michael None 0 Feb 7 11:19 foo.sock
Currently, what is shown on Cygwin is
-rwxr-xr-x 1 Michael None 0 Feb 7 11:19 foo.sock
indicating a regular file.
Right. From Cygwin's point of view, it is a regular file. There might
come a time when Cygwin's AF_UNIX implementation makes use of native
Windows AF_UNIX sockets on systems that support them. But that time is
not currently in sight.
