Bug ID: 57179
           Summary: Since Wine 7.5, file uploads in Hotline Client 1.2.3
                    hang after about 200 KB
           Product: Wine
           Version: 9.17
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: wineserver
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ---

I was uploading a file to a Hotline server from the Hotline client (1990s BBS
software used mostly on Macs) using recent versions of Wine, all the way up to
9.17 and noticed that uploads greater than about 200KB will not complete
successfully.

I found that this is working properly in wine 7.4 and earlier and I think I've
narrowed the cause down to the commit
https://gitlab.winehq.org/wine/wine/-/commit/1c6c90c7e1f1cd011e0ddb1dba47719...
. Though I'm not knowledgeable enough about wine's implementation to fix the
problem, I tested with the latest code in 64-bit mode, and if I just set
reply->nonblocking = FALSE at
https://gitlab.winehq.org/wine/wine/-/blob/6dfb84f5cbdf30c1dc0775fd4dae821ee...
the upload will succeed but obviously the client application UI will be
unresponsive while that happens.

The windows versions of the Hotline client and server are downloadable from

I tried https://gitlab.winehq.org/wine/wine/-/merge_requests/6490 and it fixes
the problem for me.

That's interesting. Perhaps the event clear should happen as soon as we call
set_async_direct_result.

If it works then that's a good news. I doubt it's the most reliable solution
for this bug, though.
