c89b4e63 2012-02-11 21:01:53 Refactor the functions that run over every event. Now there are appropriate "for each event", "for each fd", and "for each signal" helpers that they can use; this makes the code a bit simpler, and far less duplicated. This lets me turn back on the functions I disabled when removing eventlist. Additionally, check more lists for circularity in event_base_assert_ok(). Add typedefs for the callback types. Name fewer things "ctx". Adds an implementation of Floyd's tortoise-and-hare algorithm to check for circularity in TAILQs and LISTs, to avoid the abuse of flags that event_base_assert_ok() was doing before. Suggested by Dave Hart.
604569bf 2012-01-27 16:35:04 Remove the eventqueue list and the ev_next pointers. Those pointers were once used to maintain a complete list of inserted IO and signal events. But such a list is now available by walking over ev_io_map and ev_signal_map! So all they did was require extra pointer operations to maintain, and extra 8-16 bytes of storage in each struct event. To be cowardly and keep the option of going back to having this redundancy, I'm wrapping the removed code in a set of ifdefs. This is a first cut; it needs cleanups and stress-testing!! In particular, it just plain disables a couple of functions that could probably be saved. There seems to be a need for an evmap_{io,signal}_foreach() or something.

2c4b5de1 2012-01-27 14:30:41 Restore fast-path event_reinit() for slower backends We used to use the needs_reinit flag in struct eventop to indicate whether an event backend had shared state across a fork(), and therefore would require us to construct a new event backend. But when we realized that the signal notification fds and the thread notification fds would always be shared across forks, we stopped looking at it. This patch restores the old behavior so that poll, select, and win32select don't need to do a linear scan over all pending fds/signals when they do a reinit. Their life is hard enough already.
272033ef 2012-01-27 13:54:05 Make event_reinit() more robust and maintainable Previously, event_reinit required a bunch of really dubious hacks, and violated a lot of abstraction barriers to mess around with lists of internal events and "pretend" to re-add them. The new (and fairly well commented!) implementation tries to be much smarter, by isolating the changes as much as possible to the backend state, and minimizing the amount of abstraction violations. Specifically, we now use event_del() to remove events we want to remove, rather than futzing around with queues in event_reinit(). To avoid bogus calls to evsel->del(), we temporarily replace evsel with a null-object stub. Also, we now push the responsibility for calling evsel->add() down into the evmap code, so that we don't actually need to unlink and re-link all of our events.

95e2455c 2012-01-24 16:08:00 When including an -internal.h header outside the main tree, do so early Some of our unit tests and sample code need functions and structures defined in an -internal.h header. But that can freak out OpenSolaris, where stdio.h wants to define _FILE_OFFSET_BITS unless it's already defined, and then evconfig-internal.h defines it. Regular users should never ever use our -internal.h headers, so the solution is to make sure that if we're going to use them ourselves, we do so before system headers.

67a1763b 2012-01-24 14:33:10 Make regression tests run over 3x faster. This was mainly a matter of reducing timeouts and delays, paying special attention to every test that took longer than a second to finish. We could do better here; IMO anything over .7 sec is probably too long, but it's a big win as it is. Remember, interactive computing is a big win over batch processing: anything that makes you get up and walk away from the terminal might as well be making you carry your punch cards over to the mainframe.

6e41cdc1 2012-01-23 17:59:16 Fix a list corruption bug when using event_reinit() with signals present While re-adding all the events, event_reinit() could add a signal event, which could then cause evsig_add() to add the base->sig.ev_signal event. Later on its merry path through base->eventqueue, event_reinit() would find that same event and give it to event_io_add a second time. This would make the ev_io_next list for that fd become circular. Ouch!

cba48c7d 2012-01-09 16:44:53 Fix a race condition in the dns/bufferevent_connect_hostname test. As originally written, the test would only pass if the accept() callbacks for the evconnlistener were all invoked before the last of the CONNECTED/ERROR callbacks for the connecting/resolving bufferevent had its call to event_base_loopexit() complete. But this was only accidentally true in 2.0, and might not be true at all in 2.1 where we schedule event_base_once() callbacks more aggressively. Found by Sebastian Hahn.

35c5c955 2011-12-07 11:49:52 Bypass event_add when using event_base_once() for a 0-sec timeout Some people use event_base_once(EV_TIMEOUT) to make a callback get called "immediately". But this is pretty roundabout: it uses the timeout heap to immediately put the event onto the active queue, when it could just use event_active. Additionally, it can lead to surprising re-ordering behavior. This patch changes event_base_once so it bypasses event_add() and called event_active() directly on a pure-timeout event with an empty timeout.

2aa036fa 2011-11-17 11:59:41 Avoid spinning on OpenSSL reads Previously, if some sender were generating data to read on an OpenSSL connection as fast as we could process it, we could easily wind up looping on an openssl do_read operation without ever considering other sockets. The difference between this and the original method in consider_reading() is that it only loops for a single completed *frame* instead of looping until fd is drained or an error condition was triggered. {Patch split out by nickm}

7353663e 2011-11-14 10:57:15 openssl bufferevent has the same issue with writing as prior commit.
fc52dbac 2011-11-14 10:24:07 Avoid potential SSL read spinlocks OpenSSL bufferevents with deferred callbacks enabled under high load will spinlock in the function consider_reading(). This loop continues until all data has been read. Because of this condition; openssl bufferevents will never return back into event_base_loop() until SSL_read has determined data is no longer ready. As of yet I have not found a reason why this while loop exists, so this patch just swaps out while for if. If needed I can write same code which would trigger this effect; optionally libevhtp has a test.c program which can be run with the following flags: ./test -s <keyfile.pem> curl -vvvv -k -d@<HUGE_ASS_FILE> https://127.0.0.1:8081/ The return data will include the number of times the readcb got data and the length of that read. Without this patch, you are likely to see a small amount of "bytes read....", otherwise the "bytes read..." return data should show much more reasonable numbers.
