similar to: [PATCH nbdkit] freebsd: In nbdkit_nanosleep, fallback to calling nanosleep(2).

There are a couple of problems with filters trying to sleep. First, when it is time to shut down nbdkit, we wait until all pending transactions have had a chance to wind down. But consider what happens if one or more of those pending transactions are blocked in a sleep. POSIX says nanosleep is interrupted with EINTR if that thread handles a signal, but wiring up signal masks just to ensure a

The test relies on the timeout program. Also, since the nbdkit_nanosleep code relies on the Linux extension POLLRDHUP to detect early client closure, we may have to relax that part of the test when porting to platforms that lack ppoll/POLLRDHUP. (That is, while we should still be able to let a signal to the server shut down nbdkit quickly, it's harder to let a client close()ing its end cause

We noticed while writing various libnbd tests that when the delay filter is in use, there are scenarios where we had to resort to SIGKILL to get rid of nbdkit, because it was non-responsive to SIGINT. I'm still trying to figure out the best way to add testsuite coverage of this, but already proved to myself that it works from the command line, under two scenarios that both used to cause long

Description: Replace many usleep and some sleep calls with nanosleep. usleep is stated in its manual page as removed by POSIX. Contrary to its predecessors, nanosleep semantics is well defined. The replacement, which is mostly in drivers, is untested. Supplements http://bugs.debian.org/633791. Last-Update: Sat, 13 Aug 2011 14:04:48 +0300 Index:

Hi All. The recent changes to scp caused build failures on Solaris and AIX 4.2 which showed up on the tinderbox[1]. I mentioned the first to djm in email yesterday but I'm posting after finding the second, in case anyone else has seen similar problems. Solaris' nanosleep is in librt (or libposix4 in older versions) which is not linked. Adding them to configure works fine, however ldd

Hi All. There are still build errors for scp on AIX 4.2.1 due to lack of nanosleep (which you can see them live and in colour at [1]). The attached patch fixes this by using the equivalent nsleep function on AIX if it exists and nanosleep doesn't. The patch is mostly the same as the AIX portion of the previous patch for the nanosleep issue, the major difference being that the #define is in

This is a patch to configure.in which makes autoconf aware of the availability of nanosleep() on Solaris.

Hello! I''am experiencing some problems and noticed i''m not the first one. There seems to be no clue about the problem anywhere on the net so i''m reporintg it here.

Some other long-running

I put together a nanosleep() for systems without it. Please review/test before I commit. It sems to make UnixWare and Open Server 5 happy.

I think I understand now that libnbdkit.so won't break the ABI for existing plugins. Does it require that plugins for newer nbdkit use -lnbdkit (which would be a source API break) or would it still be possible to compile without this? I guess as long as plugins do not start using -no-undefined then it would still work, so it wouldn't be a source API break. I had a look into how we might

usleep() was being used without checking its return value. When the server receives SIGALRM or SIGIO the waits are shortened and random modesetting failures happen: Use nanosleep and loop around it until the requested time has elapsed. --- src/nouveau_hw.c | 2 +- src/nouveau_local.h | 6 ++++++ src/nv_bios.c | 2 +- src/nv_crtc.c | 2 +- src/nv_include.h | 1 +
