| | | | | | | | | | | In particular, the Samba dbwrap wrapper can do this for schannel_store, with the openhook set to clear the database if it can get the lock (which, being in the same process, it can).

* tevent: change version to 0.9.18Stefan Metzmacher2013-03-022-1/+84
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This release contains a lot of fixes: - Adding new timer events is now faster, if there's a large number of timer events. - sigprocmask does not work on FreeBSD to stop further signals in a signal handler. - TEVENT_NUM_SIGNALS is calculated by configure in order to support realtime signals on freebsd. - ./configure --disable-python was fixed for the standalone build. - Several crash bugs in the poll backend are fixed. - The poll backend removes deleted events from the cached pollfd array now. - The poll doesn't pass pollfd.events == 0 to poll() and maintains a list of disabled events, instead of consuming 100% cpu and/or triggering the callers handler. - The poll backend detects POLLNVAL and reports EBADF instead of consuming 100% cpu. - The select backend supports separate handlers for TEVENT_FD_READ and TEVENT_FD_WRITE. - The poll and select backends are now doing fair queuing of fd events. - The epoll has better error checking and supports separate handlers for TEVENT_FD_READ and TEVENT_FD_WRITE. - The standard backend was rewritten to be a tiny wrapper on top of epoll with a fallback to poll, which means that it doesn't use select directly anymore. - TEVENT_TRACE_BEFORE_LOOP_ONCE and TEVENT_TRACE_AFTER_LOOP_ONCE are added in order to allow the application to hook in before and after the loop_once() backend function is called. The TEVENT_HAS_LOOP_ONCE_TRACE_POINTS define can be used to detect the new feature.

* tevent: optimize adding new zero timer eventsStefan Metzmacher2013-03-016-31/+113
| | | | | | | | | | | | | | Such events were used before we had immediate events. It's likely that there're a lot of this events and we need to add new ones in fifo order. The tricky part is that tevent_common_add_timer() should not use the optimization as it's used by broken Samba versions, which don't use tevent_common_loop_timer_delay() in source3/lib/events.c.

* tevent: optimize adding new timer eventsStefan Metzmacher2013-03-011-8/+24
| | | | | | | | | | | | | | | | | | | | | | As new timestamps typically get higher:-) it's better to traverse the existing list from the tail. This is not completely optimal, but it should be better than before. A second optimization could be done for zero timestamps, we would just remember the last_zero_timer, but that would change the internal ABI. Normally thatshould not be a poblem, but the Samba's source3/lib/events.c abuses tevent_internal.h from the current source tree, even if an external tevent.h is used. The other problem is that it makes use of tevent_common_add_timer() without using tevent_common_loop_timer_delay().
