b8f222e0 2009-11-19 21:14:31 On FreeBSD and other OSes, connect can return ECONREFUSED immediately; instead of failing the function call, pretend with faileld in the callback. svn:r1553

f070a4ae 2009-11-18 23:18:55 Do the proper hack for the (Open)BSD getaddrinfo quirk. From evutil.c: Some older BSDs (like OpenBSD up to 4.6) used to believe that giving a numeric port without giving an ai_socktype was verboten. We test for this so we can apply an appropriate workaround. If it turns out that the bug is present, then: - If nodename==NULL and servname is numeric, we build an answer ourselves using evutil_getaddrinfo_common(). - If nodename!=NULL and servname is numeric, then we set servname=NULL when calling getaddrinfo, and post-process the result to set the ports on it. We test for this bug at runtime, since otherwise we can't have the same binary run on multiple BSD versions. svn:r1550
07ce7f99 2009-11-18 21:17:00 Make our failing-connection bufferevent test more tolerant. I thought we had a way to do connect() that would never fail immediately, but always wait for a moment before failing. It turns out that on FreeBSD it can fail immediately. This is not FreeBSD's fault, or even a real bug anywhere but in the unit test. svn:r1549
cf749e22 2009-11-18 21:16:53 Add a temporary workaround for an ssl bug found on FreeBSD. Basically, we only want to report the 'connected' event because of the socket connect() finishing when we have an actual socket bufferevent; on an SSL bufferevent, 'connected' means 'SSL connection finished.' This isn't FreeBSD's fault: it just has a connect() that tends to succeed pretty early. svn:r1548
9bf124bf 2009-11-18 21:16:47 Build correctly with mm replacement turned off. svn:r1547
767eb70f 2009-11-18 21:16:33 Fix compilation with threading disabled. svn:r1546
d7d1f1da 2009-11-17 20:31:09 Move responsibility for IOCP callback into bufferevent_async. This patch from Chris Davis saves some callback depth, and adds proper ref-counting to bufferevents when there's a deferred evbuffer callback inflight. It could use a couple more comments to really nail down what its invariants are. svn:r1543
201d8d0b 2009-11-17 18:29:44 Clarify even more about various system-specific problems with getaddrinfo svn:r1542
9151d000 2009-11-17 03:36:43 Use the common-case code from getaddrinfo_common *always*; OS differences are just too huge. svn:r1541
3451c870 2009-11-17 02:57:32 Never pass our weird flags to the system getaddrinfo. Make sure there is no overlap between flag values. svn:r1540
625a261a 2009-11-17 02:40:14 OpenBSD demands that sys/types.h be included before sys/socket.h svn:r1539
888007f9 2009-11-17 02:38:19 Windows *does* have getservbyname, no matter what autoconf says. TODO: figure out why autoconf is confused about this. svn:r1538
86f57420 2009-11-16 22:25:46 Add two implementations of getaddrinfo: one blocking and one nonblocking. The entry points are evutil_getaddrinfo and evdns_getaddrinfo respectively. There are fairly extensive unit tests. I believe this code conforms to RFC3493 pretty closely, but there are probably more issues. It should get tested on more platforms. This code means we can dump the well-intentioned but weirdly-implemented bufferevent_evdns and evutil_resolve code. svn:r1537
72bafc17 2009-11-16 22:23:55 Remove the stupid brokenness where DNS option names needed to end with a colon. svn:r1536
f9de8670 2009-11-16 22:23:06 Fix a declaration of __func__ in rpcgen. svn:r1535
18a8cfac 2009-11-15 19:00:12 Prefer calloc(a,b) to malloc(a*b). via openbsd. svn:r1531
629a6133 2009-11-15 18:59:59 When running set[ug]id, don't check the environment. Idea from OpenBSD, but made a bit more generic to handle uncivilized lands that do not define issetugid. svn:r1530
e2b2de79 2009-11-15 18:59:48 Use arc4random() for dns transaction ids where available. Patch taken from OpenBSD svn:r1528
c79a45e0 2009-11-14 21:54:30 Fix a couple of event_debug calls. svn:r1527
74871cac 2009-11-09 19:37:27 Change event_base.activequeues to "array of eventlist". Previously, event_base.activequeues was of type "array of pointers to eventlist." This was pointless: none of the eventlists were allowed to be NULL. Worse, it was inefficient: - It made looking up an active event queue take two pointer deferences instead of one, thus risking extra cache misses. - It used more RAM than it needed to, because of the extra pointer and the malloc overhead. Also, this patch fixes a bug where we were saying calloc(N,N*sizeof(X)) instead of calloc(N,sizeof(X)) when allocating activequeues. That part, I'll backport. Also, we warn and return -1 on failure to allocate activequeues, rather than calling event_err. svn:r1525
cdf58009 2009-11-09 19:37:21 Change an OOM err to a warn in event_tagging.c svn:r1524
26573d3d 2009-11-09 19:37:15 Change an err to a warn in bufferevent_openssl svn:r1523
37e23f80 2009-11-09 18:50:20 Patch from Ryan Phillips: accept ipv6 addresses returned by getaddrinfo in http.c svn:r1522
b2fe4aed 2009-11-09 18:36:34 Unit tests for got_break and got_exit. svn:r1521
e88079a8 2009-11-09 18:30:57 Make persistent timeouts more accurate. Previously, if the user scheduled a persistent timeout for {1,0}, we would schedule the first one at "now+one second", and then when we were about to run its callback, we would schedule it again for one second after that. This would introduce creeping delays to the event that was supposed to run every second. Now, we schedule the event for one second after it was _last scheduled_. To do this, we introduce internal code to add an event at an _absolute_ tv rather than at now+tv. svn:r1520
59be8942 2009-11-09 18:30:48 Make sure that common timeouts are inserted in-order. This code should be a no-op, except under strange thread contention situations. svn:r1519
ab96b5f3 2009-11-09 18:30:33 Add an option to disable the timeval cache. svn:r1518
693c24ef 2009-11-09 17:16:30 Implement queued timeouts for case where many timeouts are the same. Libevent's current timeout code is relatively optimized for the randomly scattered timeout case, where events are added with their timeouts in no particular order. We add and remove timeouts with O(lg n) behavior. Frequently, however, an application will want to have many timeouts of the same value. For example, we might have 1000 bufferevents, each with a 2 second timeout on reading or writing. If we knew this were always the case, we could just put timeouts in a queue and get O(1) add and remove behavior. Of course, a queue would give O(n) performance for a scattered timeout pattern, so we don't want to just switch the implementation. This patch gives the user the ability to explicitly tag certain timeout values as being "very common". These timeout values have a cookie encoded in the high bits of their tv_usec field to indicate which queue they belong on. The queues themselves are each triggered by an entry in the minheap. See the regress_main.c code for an example use. svn:r1517
784b8773 2009-11-06 21:46:57 We do not work any more without an event-config.h; stop pretending that it is meaningful to check for HAVE_CONFIG_H svn:r1516
4d48cf61 2009-11-06 21:13:25 Fix kqueue.c build on GNU/kFreeBSD systems. Yes, some people like to have a BSD-family kernel (thus getting kqueue) with a GNU-family libc (thus occasionally mandating _GNU_SOURCE). Thanks to Debian for noticing this. svn:r1514
5ec43fe4 2009-11-06 17:12:39 Fix a miscalculated realloc() size in win32select.c. This bug was introduced by the code to make the backend able to safely release the base lock while calling select(). Also, we change win32select.c to the same 32-fds-to-start default as the rest of the backends, so that the main/many_events test can test it. It was at 64-to-start, so the test wasn't hitting it. svn:r1513
ae5fbf49 2009-11-05 22:24:21 Actually add the new dns-example.c code. :p svn:r1512
d2e7e65d 2009-11-05 22:19:09 Move the evdns sample code into the sample directory and fix it not to use any deprecated APIs. svn:r1511
ac633aeb 2009-11-05 21:22:23 Fix some build warnings on MSVC, mostly related to signed/unsigned comparisons. svn:r1510
43ba6693 2009-11-05 20:45:07 Export nmakefiles in source distribution. svn:r1509
4ca9efea 2009-11-05 20:40:11 Add nmake files to build with MSVC. Right now, they just make static libraries and unit tests. They probably set lots of options wrong. svn:r1507
25a5e681 2009-11-05 20:37:19 Build fixes for MSVC svn:r1506
d3401928 2009-11-05 18:49:08 Rename win32.c to win32select.c, and take it out of the WIN32-Code ghetto. svn:r1504
d14c3b45 2009-11-05 18:25:46 Fix another ssize_t user svn:r1503
a0b30263 2009-11-05 18:07:27 Remove win32-code/config.h. It was apparently confusing. svn:r1502
34f28e08 2009-11-05 15:57:22 Fix a few types to use compatible versions svn:r1501
47bad8ab 2009-11-04 20:17:32 Implement size limits on HTTP header length and body length. Patch from Constantine Verutin, simplified a little. svn:r1500
86db1c85 2009-11-04 05:19:26 Commit ConnectEx code to get connect working with async bufferevents. This is code by Chris Davis, with changes to get the unit tests failing less aggressively. The unit tests for this code do not completely pass yet; Chris is looking into that. If they aren't passing by the next release, I'll turn off this code. svn:r1499
6ca32df1 2009-11-04 03:54:05 Add a missing include for win32. svn:r1498
f9c65580 2009-11-03 20:42:32 Oops; add missing bufferevent_evdns.c file svn:r1497
0b9eb1bf 2009-11-03 20:40:48 Add a bufferevent function to resolve a name then connect to it. This function, bufferevent_socket_connect_hostname() can either use evdns to do the resolve, or use a new function (evutil_resolve) that uses getaddrinfo or gethostbyname, like http.c does now. This function is meant to eventually replace the hostname resolution mess in http.c. svn:r1496
fcc7668c 2009-11-03 20:05:06 Fix one IOCP-callback signature I missed svn:r1495
0fd0255f 2009-11-03 19:54:56 Remove compat/sys/_time.h I've gone through everything that it declared to see where it was used, and it seems that we probably don't need it anywhere. Here's what it declared, and why I think we're okay dropping it. o struct timeval {} (Used all over, and we can't really get away with declaring it ourselves; we need the same definition the system uses. If we can't find struct timeval, we're pretty much sunk.) o struct timespec {} (Used in event.c, evdns.c, kqueue.c, evport.c. Of these, kqueue.c and event.c include sys/_time.h. event.c conditions its use on _EVENT_HAVE_CLOCK_GETTIME, and kqueue() only works if timespec is defined.) o TIMEVAL_TO_TIMESPEC (Used in kqueue.c, but every place with kqueue has sys/time.h) o struct timezone {} (event2/util.h has a forward declaration; only evutil.c references it and doesn't look at its contents.) o timerclear, timerisset, timercmp, timeradd, timersub (Everything now uses the evutil_timer* variants.) o ITIMER_REAL, ITIMER_VIRTUAL, ITIMER_PROF, struct itemerval (These are only used in test/regress.c, which does not include _time.h) o CLOCK_REALTIME (Only used in evdns.c, which does not include _time.h) o TIMESPEC_TO_TIMEVAL o DST_* o timespecclear, timespecisset, timespeccmp, timespecadd, timespecsub o struct clockinfo {} o CLOCK_VIRTUAL, CLOCK_PROF o TIMER_RELTIME, TIMER_ABSTIME (unused) svn:r1494
0aa6f513 2009-11-02 20:59:13 Fix remaining AcceptEx issues. svn:r1492
e794d716 2009-11-02 20:20:40 Clean up acceptex code some more: add locking, single-threading, enable/disable. svn:r1491
a84c87d7 2009-11-02 19:51:26 Refactor IOCP callback interface Chris Davis points out that GetQueuedCompletionStatus sometimes returns false not to report "No events for you!" but instead to report "An overlapped operation failed." Add a way to tell an event_overlapped that its operation failed. svn:r1490
9a772148 2009-11-02 19:31:29 Compilation and correctness fixes for IOCP listener code. svn:r1489
8283b2f0 2009-11-02 19:30:25 Fix a major parenthesis bug in EVUTIL_UPCAST. Fortunately, this didn't hurt anything previously, since we had no actual users of the macro where the offset of the base type wasn't 0. svn:r1488
5f1d6e64 2009-11-02 17:42:16 Add more IOCP tests. They might not pass yet. svn:r1487
5d2c1650 2009-11-02 17:42:09 More refactoring for IOCP listener code svn:r1486
e90e14fb 2009-11-02 16:31:13 Call the bufferevent_flush_mode variable "mode" more consistently in the documentation. Spotted by Alex. svn:r1485
7f0ad2f6 2009-11-02 16:17:06 Fix an errant user of ssize_t to use ev_ssize_t. My usual strategy of grep '[^_]ssize_t' had apparently failed me, since this ssize_t was in the first column. Resolves bug 2890434; spotted by Mihai Draghicioiu. svn:r1484
315fde1a 2009-10-30 22:43:53 Remove some duplicate code in kqueue.c and fix a small memory leak. svn:r1483
96c6956e 2009-10-30 22:43:30 Add a "many events" regression test. This is a glass-box test to get more coverage on the event loop backends. We've run into bugs here before with fencepost errors, and it turns out that none of our unit tests had enough events to exercise the resize code. Most of the backends have some kind of logic that resizes an array when: - The highest fd is too high - The number of events added since the last iteration of the loop is too high - The number of active events is too high. This test hits all 3 cases, and increases coverage in select.c by 7%, in poll by 1%, and in kqueue by 9%. svn:r1482
516452b7 2009-10-30 21:08:29 Keep openssl errors associated with the right bufferevent object. OpenSSL has a per-thread error stack, and really doesn't like you leaving errors on the stack. Rather than discard the errors or force the user to handle them, this patch pulls them off the openssl stack and puts them on a stack associated with the bufferevent_openssl. If the user leaves them on the stack then, it won't affect any other connections. This bug was found by Roman Puls. Thanks! svn:r1481
20f5bdfd 2009-10-29 19:25:33 Refactor evconnlistener to allow multiple implementations; add an (incomplete, not-yet-integrated) IOCP implementation. svn:r1480
fa313f28 2009-10-29 18:30:43 Extract XP-only functions when initializing the IOCP port svn:r1479
9976f1e7 2009-10-29 17:11:12 reformat weird indentation in dns tests svn:r1478
3c2198cb 2009-10-29 17:10:36 Unit test for reverse ipv6 lookup svn:r1477
5b3fb5bf 2009-10-29 16:35:20 More documentation and unit tests for event_tagging. svn:r1476
1eadb3e3 2009-10-29 16:35:15 Actually use the logic in select.c designed to make the out_sets threadsafe. svn:r1475
c70c2593 2009-10-29 16:35:09 Unit test for strlcpy svn:r1474
e9098203 2009-10-27 18:25:19 Fix from Chris Davis: get error-logging to be happy on win32. svn:r1473
904b5721 2009-10-27 06:47:25 Avoid calling exit() during event_base_new*() Previously, each of the three make-an-event-base functions would exit under different, weird circumstances, but return NULL on others. - All three would exit on OOM sometimes. - event_base_new() and event_init() would die if all backends were disabled. - None of them would die if the socketpair() call failed. Now, only event_init() exits on failure, and it exits on every kind of failure. event_base_new() and event_base_new_with_config() never do. svn:r1472
a2a7d1d1 2009-10-27 05:16:32 Do not call the locking variant of event_add or event_active in some cases when we know we have the lock. svn:r1471
d386dc89 2009-10-27 05:16:23 Refactor event_assing even more to avoid unnecessary calls svn:r1470
e9ee1057 2009-10-27 04:25:45 Give event_assign a return value, and make it less inclined to exit(). We also refactor event_assign so that it is the core function, and event_set() is only the wrapper. svn:r1469
10cf631e 2009-10-27 04:04:07 Do not add a newline to the end of log statements. svn:r1468
369aafc4 2009-10-27 04:03:58 Refactor kq_init error handling. svn:r1467
ed0e91e0 2009-10-27 04:03:50 New test flag to suppress logging for one test. svn:r1466
7f10fac3 2009-10-26 20:07:06 Note assert-related change in changelog svn:r1465
2e36dbe1 2009-10-26 20:00:43 Use EVUTIL_ASSERT() consistently instead of assert. svn:r1464
37c3456d 2009-10-26 20:00:08 Add an EVUTIL_ASSERT() to replace our calls to assert(). The big difference here is that EVUTIL_ASSERT() passes its message on via event_errx() before aborting, so that the application has a prayer of noticing and recording it. svn:r1463
a8267663 2009-10-26 19:59:51 API to replace all calls to exit() with a user-supplied fatal-error handler. Also, add unit tests for logging. svn:r1462
38aec9ec 2009-10-23 22:38:35 Tweaks to IOCP interface. svn:r1461
7b107249 2009-10-23 22:07:05 Fix my fix for the bufferevent_connect_fail() test. svn:r1460
879420a7 2009-10-23 22:00:29 Expose a narrow window to the IOCP code. svn:r1459
c119e4a1 2009-10-23 17:40:00 Improve the behavior of le-proxy in a few cases. svn:r1458
fdd11c00 2009-10-21 19:21:05 Make the bufferevent_connect_fail test faster on OSX. It seems that connecting to a listener that is bound but not accepting or listening doesn't give a 'connection refused' error on OSX, but rather makes the connect() time out after 75 seconds. I couldn't find any way to make the timout shorter. Fortunately, closing the listener after a second or so makes the desired error occur after another second or so. svn:r1457
b73ad7bc 2009-10-21 18:48:22 Treat the bitwise OR of two enum values as an int. This makes our interfaces usable from C++, which doesn't believe you can say "bufferevent_socket_nase(base, -1, BEV_OPT_CLOSE_ON_FREE|BEV_OPT_DEFER_CALLBACKS)" but which instead would demand "static_cast<bufferevent_options>(BEV_OPT_CLOSE_ON_FREE| BEV_OPT_DEFER_CALLBACKS))" for the last argument. Diagnosis and patch from Chris Davis. svn:r1456
4fbac2a5 2009-10-21 07:00:19 Test failing case of bufferevent_connect(). Code by Chris Davis. svn:r1455
d8164d0c 2009-10-21 07:00:14 Fix win32 connect() event handling. Christopher Davis reported: Connection failures aren't reported on Windows when using bufferevent_socket_connect, because Windows uses select's exceptfds to notify of failure, and libevent treats them like read events. Only the write event handler is currently used to handle connection events. We should think hard about this one, since it changes behavior from 1.4.x. Anything that worked on Mac/Unix before will work more consistently on Windows now... but this might break stuff that worked only on Windows, but nowhere else. Patch from Chris Davis. svn:r1454
b89b58b5 2009-10-21 06:03:00 OSX compilation issues svn:r1453
c9c4ec26 2009-10-21 05:36:27 Remove an EVBASE_RELEASE_LOCK that I missed. svn:r1452
ed748a48 2009-10-21 04:45:59 Fix win32 compilation. svn:r1451
6b22e74a 2009-10-21 03:54:00 Add locking to event_base_loop. This is harder than it sounds, since we need to make sure to release the lock around the key call to the kernel (e.g., select, epoll_wait, kevent), AND we need to make sure that none of the fields that are used in that call are touched by anything that might be running concurrently in another thread. I managed to do this pretty well for everything but poll(). With poll, I needed to introduce a copy of the event_set structure. This patch also fixes a bug in win32.c where we called realloc() instead of mm_realloc(). svn:r1450
50825466 2009-10-21 02:14:16 Fix windows compilation warnings. svn:r1449
e1c9b84a 2009-10-19 16:20:12 Fix compilation for listener.h for C++ - missing extern "C". Patch from Ferenc Szalai. svn:r1448
b812563a 2009-10-16 13:20:16 Add a note that we should change previous_to_last to last_with_space svn:r1447
f3dee9e8 2009-10-16 13:20:09 Correct the signatures for the evmap_io_* functions to use evutil_socket_t. svn:r1446
e3fd294a 2009-10-16 13:19:57 Spelling fixes in comments and strings. svn:r1445
