2007-10-10r23792: convert Samba4 to GPLv3Andrew Tridgell10-30/+20
There are still a few tidyups of old FSF addresses to come (in both s3 and s4). More commits soon. (This used to be commit fcf38a38ac691abd0fa51b89dc951a08e89fdafa)

2007-10-10r22968: andrew bartlett pointed out that the parent process could add a fd toAndrew Tridgell3-33/+33
the epoll context which would then appear in the children. To fix this we need to check for pid changes in more places. Luckily on platforms where we have epoll(), getpid() is very very cheap. (This used to be commit 4f84e6d569f9c9d7dd902f4550735f3ce2d3b424)

fork(). See http://junkcode.samba.org/ftp/unpacked/junkcode/epoll_fork.c for why this is needed (This used to be commit 6d06132ea9c5a1c7d098ba13f4146dc60e811e44)
2007-10-10r22830: merged the latest lib/events updates from ctdb to Samba4. ThisAndrew Tridgell9-8/+74
includes a new EVENT_FD_AUTOCLOSE flag that prevents race conditions where code using fd events might close a fd before releasing the struct fd_event. That causes headaches for epoll. (This used to be commit f1ad216de13b154a1f8747a44b0970dcc47a784a)
2007-10-10r22661: optimize the handling of directly triggered timed events:Stefan Metzmacher6-48/+60
- if someone adds a timed_event with a zero timeval we now avoid serval gettimeofday() calls and the event handler doesn't get the current time when it's called, instead we also pass a zero timeval - this also makes sure multiple timed events with a zero timeval are processed in the order there're added. the little benchmark shows that processing 2000000 directly timed events is now much faster, while avoiding syscalls at all! > time ./evtest (with the old code) real 0m6.388s user 0m1.740s sys 0m4.632s > time ./evtest (with the new code) real 0m1.498s user 0m1.496s sys 0m0.004s metze@SERNOX:~/devel/samba/4.0/samba4-ci/source> cat evtest.c #include <stdio.h> #include <stdint.h> #include <sys/time.h> #include <talloc.h> #include <events.h> static void dummy_fde_handler(struct event_context *ev_ctx, struct fd_event *fde, uint16_t flags, void *private_data) { } static void timeout_handler(struct event_context *ev, struct timed_event *te, struct timeval tval, void *private_data) { uint32_t *countp = (uint32_t *)private_data; (*countp)++; if (*countp > 2000000) exit(0); event_add_timed(ev, ev, tval, timeout_handler, countp); } int main(void) { struct event_context *ev; struct timeval tval = { 0, 0 }; uint32_t count = 0; ev = event_context_init(NULL); event_add_fd(ev, ev, 0, 0, dummy_fde_handler, NULL); event_add_timed(ev, ev, tval, timeout_handler, &count); return event_loop_wait(ev); } (This used to be commit 4db64b4ce2320b88d648078cbf86385f6fb44f1f)

now maintained separately in bzr at http://people.samba.org/bzr/jelmer/samba-gtk This also adds some more headers to the list that is installed and a couple of extra #include lines so these headers can be used externally without problems. (This used to be commit 07652f65ce7a5b19130f1a27cbf0e1e5fae13454)
2007-10-10r21212: detect if the kernel does not support integrated epoll/aio when theAndrew Tridgell1-1/+11
event context is created. This allows the LOCAL-EVENT test to pass on systems with have libaio but not the necessary kernel patches (This used to be commit 2ff8abf0022824e6ae93019ee1b3391e651a8ee7)
2007-10-10r21171: fixed a bug related to recursive event handling.Andrew Tridgell4-11/+7
If this happens: - two sockets are readable, and select/epoll/aio returns both of them - read event on socket1 is called - inside that read event an event_loop_once is called, this returns that socket2 is readable - read event on socket2 is called - event_loop_once returns - top level event handler then calls read event on socket2 (as it still has that listed as readable) - read handler for socket2 returns zero byte read, which is interpreted as end of file - socket is incorrectly closed this happened with ctdb, but it could happen anywhere (just rarely). The fix is trivial - ensure we break out of the event loop when we have been called recursively. (This used to be commit e042002bb5ee8974220e1ade56b64389571f75a6)
2007-10-10r20989: don't mark epoll as set until after the io_submit() succeedsAndrew Tridgell1-1/+1
this is part of the solution to LOCAL-EVENT on fort (This used to be commit 35f62bc12559e355d4ac73018afe255ea7c5866b)
2007-10-10r20984: Try to ensure we can't have sig_state dissapear before se.Andrew Bartlett1-0/+5
I think this happens when both are eventual children of the autofree context. (Trying to track down a valgrind error on fort). Andrew Bartlett (This used to be commit aee751497ca738fa0de72dd0748590a74d5af2fd)
2007-10-10r20960: attempt to fix a valgrind error in the signals backend.Andrew Tridgell1-38/+48
This also reduces the static data in the signal backend when not using signals to 4 bytes. (This used to be commit 071a6e8eb1861b10b8a7aa61470f21a546ffa0ca)
2007-10-10r20941: avoid races in the block/unblock codeAndrew Tridgell1-3/+11

2007-10-10r20930: use sigaction() instead of signal()Andrew Tridgell4-11/+87
add support for sa_flags argument to event_add_signal(). These are passed to sigaction(). Special handling is provided for SA_RESETHAND (which tells the event system to remove the handler after the signal) and SA_SIGINFO which allows the siginfo structure to be received per signal (This used to be commit 1bb10b6cf7d717ad21834e73a4ca4b22b5fb6f0a)

2007-10-10r20928: added signal events to lib/eventsAndrew Tridgell10-2/+261
Jeremy asked for this to allow Samba3 to use the Samba4 events library see torture/local/event.c for an example (This used to be commit 7e105482ff9a3da6b4708ff99a64f1881614fc5f)

2007-10-10r20788: - remove epoll configure checks from libreplaceStefan Metzmacher3-17/+15
- fix epoll configure checks for the epoll and aio events backends - we should only activate the epoll backend if sys/epoll.h and epoll_create() are found - we should only activate the aio backend if sys/epoll.h, epoll_create(), libaio.h and io_getevents() are found hopefully fix the build on 'bnhtest' in the build farm... metze (This used to be commit d46a5efb03ea1df50567cad00e1589870cdb31fe)

2007-10-10r20539: - split the common timer related events code into events_timed.cAndrew Tridgell10-265/+1137
- make it easier to plug in a new events backend - add simpler 'select' and 'epoll' backends This is part of the effort to add good AIO support. The events_aio.c backend is done, but sometimes dies with a SEGV, which is why it isn't enabled yet. (This used to be commit 934f18283dbc7958944931a93a854526bcd54884)
2007-10-10r20104: this is a alternative events backend, which uses a hybrid of aio andAndrew Tridgell1-0/+518
epoll. It is not linked in anywhere yet - I'm committing it in case anyone else wants to have a look at it. The concept is quite strange really, but it seems to be the only way that Linux 2.6.x can currently use a unified event model allowing for AIO events and socket events to be waited for by a single unified event wait function. You setup a epoll system, then setup a weird aio event that points at the epoll system, then use io_getevents() to actually do the waiting. I'm hoping that kevents or a proper integration of epoll will allow us to avoid ths rather hackish scheme, but meanwhile this is the only path to proper AIO in Samba on Linux (without a horrible signals mess) (NOTE: this code requires some kernel patches to work at the moment) (This used to be commit 195051fdee341e8d8cb76e5c91dcc0f6c246a870)
