https://bugs.winehq.org/show_bug.cgi?id=52332 Bug ID: 52332 Summary: Incoming data on socket only satisfies the first async I/O request in the queue Product: Wine Version: 7.0-rc3 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: wineserver Assignee: wine-bugs(a)winehq.org Reporter: jinoh.kang.kr(a)gmail.com CC: z.figura12(a)gmail.com Distribution: --- async_set_result() calls async_reselect() *before* de-queueing the async request, which means that async_waiting() will return 0 since it *still* sees a pending I/O request in the queue. The problem manifests when the target file object is a socket. Sockets use async_waiting() to determine whether the next poll event mask shall include the POLLIN flag. Since async_waiting() returns zero, sock_reselect() skips the flag. This hangs any subsequent I/O read requests. Known impacted applications include KakaoTalk (an instant messaging application): this bug causes the log-in to timeout, preventing normal use of the app. I have the fix, but I am yet to bisect the regression commit. -- Do not reply to this email, post in Bugzilla using the above URL to reply.
