This is working now, and incorporates all of the changes in Eric's review, *except* that it still doesn't retire commands (although this seems to make no obvious difference, except possibly a performance and memory impact). Rich.

select() has a maximum value for the FDs it can monitor, and since the libguestfs library can be used in other applications, this limit may be hit by users in case lots of FDs are opened. As solution, switch to poll(): it has a slightly better interface to check what changed and for which FD, and it does not have a limit in the value of the FDs monitored. poll() is supported on the platforms we

It is just a wrapper around select(2).

Since Eric's improvements to the command queue in commit 6af72b8 (and following) there's now a queue of commands waiting to be issued stored in the handle, and there's no need to issue commands only from the ready state. We can therefore remove the want_to_send logic, queue as many commands as possible, and don't need to test if the socket is ready for POLLOUT. This commit also

** NOT WORKING ** This patch shows how to integrate libnbd and the glib main loop. Posted mainly as a point of discussion as it doesn't quite work yet. Rich.

Hi I have upgraded from samba 3.6.19 to samba 4.0.13 on Debian Wheezy 64-bit with Samba 4.0.13 from wheezy-backports. I use winbind to authenticate against a two-server AD domain on Server 2012 functional level and forced LDAPS. After upgrading from 3.6.19 to 4.0.13 everything still works for me as usual. That is samba shares authentication, all things relying on the keytab, SSO logins with SSH

Greetings, I am porting the openssh-portable 6.8 release to the HP NonStop (NSE) platform. Prior versions were no real problem, with minor tweeks. However, with the inclusion of regress/netcat.c, which depends on arpa/telnet.h, we have an issue. Unfortunately, the platform does not have this file, nor anything like it - telnet is done rather differently. We do have a version of netcat (0.7.1

Dovecot Version: 2.2.12 Postfix Version: 2.9.6 Hello I've configured the quota-status service (socket and port).

This is a continuation of a discussion we were having on IRC. The problems with IRC are it's not recorded and it's hard to have deep technical conversations. I hope this is a decent summary. Problem simply stated: Certain NBD servers (qemu-nbd in particular) are able to simultaneously read and write on a socket. ie. They can be simultaneously reading a request and writing the reply to

nmbd has been dying on me occasionally. I'm running mandrake 9.2 with samba3-server-3.0.0-2mdk. We've got our users in ldap but I'd seen this symptom previously when I was using an earlier version of samba that didn't support ldap. There is nothing useful in the logs and a PS shows a nmb process still running. This last time around, I had a ptrace running on both nmbd

I managed to get a build of the async Rust handle compiling on FreeBSD (although the cirrus CI appears to not actually run 'make check' on non-Linux machines, at least when run on my fork): https://gitlab.com/ebblake/libnbd/-/jobs/4985192286 However, I'd really like Tage's review on patch 2 to see if my Rust makes sense.

Make nbd_poll slightly more like poll(), allowing a user to detect timeouts by returning 0 on timeout and 1 when we made progress. It turns out that none of our internal uses ever expect a timeout (we only call nbd_internal_poll with timeout==-1 because we expect a reply from the server), but the public function might as well be nicer. Also handle POLLERR (server closed its read end, so our

While working on a new test of what happens when the server goes away while commands are in flight, I managed to hit a race where I hit death from SIGPIPE instead of a clean transition to the DEAD state. I also found myself wanting to use nbd_poll from the test, but with a way to distinguish between the state machine progressing vs. hanging. Eric Blake (2): socket: Avoid SIGPIPE where possible
