similar to: [nbdkit PATCH] delay: Avoid numeric overflow

Previously the file plugin supported ‘rdelay’ and ‘wdelay’ parameters for injecting delays (for testing) into read and write requests. This moves the functionality to a new delay filter so that it can be used with any plugin. --- TODO | 3 - configure.ac | 1 + filters/Makefile.am | 1 + filters/delay/Makefile.am

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

Require the root= parameter is passed to specify which root (apppliance) to mount. Libguestfs has done this since 2012. The other two patches are small code refactorings in the init program. Rich.

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

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.

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, I hit a bizare problem with dovecot 2.2.7 on debian 9 with LMTP enabled and auth/penalty disabled as documented here : https://wiki.dovecot.org/Authentication/Penalty Use case : I run a swaks command to send an email to an exim4 that tries to make a callout to dovecot-lmtp. At RCPT TO: swaks hangs 5.0<something-small> seconds then process normally (exim is waiting for callout

Hi, I can confirm that in the bad behavior, the 5 second delay occurs at each AUTH in our case. I think the configuration we have kill auth process at each end of AUTH (and fork a new one for next next AUTH). I think the "disable" flag is local to the process that is killed / respawned. A collegue of mine, Laurent Guerby, has found a workaround for us and it's findings seems

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

Rather than failing to compile on platforms which lack POLLRDHUP such as FreeBSD, simply fallback to the old method of sleeping. This leaves the porting suggestions as a comment in case someone wants to implement a better solution for particular platforms. --- server/public.c | 38 ++++++++++++++++++++++++-------------- 1 file changed, 24 insertions(+), 14 deletions(-) diff --git

This patch isn't complete (patch 6/6 isn't finished) so it's just for discussion, although it does compile and run. This introduces to nbdkit a concept of "filters" which can be placed in front of plugins to modify their behaviour. Some examples where you might use filters: * Serve a subset of the data, such as (offset, range) or a single partition from a disk image.

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

Instead of specifying a device name (eg. root=/dev/sdb), this permits specifying an ext4 volume UUID (root=UUID=12345678-...). This allows the appliance to be robust against the non-determinism of SCSI device enumeration. --- init/init.c | 226 +++++++++++++++++++++++++++++++++++++++++++++++++++--------- 1 file changed, 192 insertions(+), 34 deletions(-) diff --git a/init/init.c b/init/init.c

This patch is the minimum possible to add virtio-scsi support to febootstrap. Problem: SCSI devices are detected asynchronously after the Linux kernel module is loaded. The usual solutions to this involve scsi_wait_scan (deprecated apparently) or udev. However febootstrap doesn't use udev, and adding it is a ton of work with a very uncertain outcome. So the minimum possible change is to
