2012-08-21build: Remove special case for the build farmAndrew Bartlett1-3/+3
Except in the formatting of the selftest output, this removes the special case of the build farm, so that an autobuild, a manual make test and the build farm are more similar.

2012-03-31s3-aio-fork: Fix a segfault in vfs_aio_forkVolker Lendecke1-7/+9
aio_suspend does not signal the main process with a signal, it just waits. The aio_fork module does not use the signal at all, it directly calls back into the main smbd by calling smbd_aio_complete_aio_ex. This is an abstraction violation, but the alternative would have been to use signals where they are not needed. However, in wait_for_aio_completion this bites us: With aio_fork we call handle_aio_completed twice on the same aio_ex struct: Once from the call to handle_aio_completion within the aio_fork module and once from the code in wait_for_aio_completion. This patch fixes it in a pretty bad way by introducing flag variables and more state. But the mid-term plan is to replace the posix aio calls from the vfs and do pread_send/recv and pwrite_send/recv at the vfs layer, so this will significantly change anyway. Thanks to Kirill Malkin <kirill.malkin@starboardstorage.com> for reporting this crash! Autobuild-User: Volker Lendecke <vl@samba.org> Autobuild-Date: Sat Mar 31 15:25:55 CEST 2012 on sn-devel-104

We end up here multiple times. There's no real point putting the events into the child struct, at the end of this routine we need to free them anyway.

2011-01-14s3:vfs aio_fork children do not go awayChristian Ambach1-1/+13
on RHEL 5.5, recvmsg() does not return when it is reading from the socket and the process on the other side closes its connection. This left aio children around that should have gone already and were just wasting system resources. This patch makes the child go away by writing invalid data to it so that the child exits.

2010-06-04Fix a long-standing bug with async io that would only be triggered by SMB2.Jeremy Allison1-0/+124
On normal or shutdown close, ensure we wait for any pending IO to complete before returning. Implement a blocking aio_suspend inside vfs_aio_fork.c. These changes pass make test when the aio_fork module is used by default on the test shares. Jeremy.
