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 | |
|
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 | |

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 | |
|
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 | |
|
7f10fac3 | 2009-10-26 20:07:06 | Note assert-related change in changelog svn:r1465 | |
|
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 | |
|
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 | |
|
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 | |
|
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 | |
 |
e1c9b84a | 2009-10-19 16:20:12 | Fix compilation for listener.h for C++ - missing extern "C". Patch from Ferenc Szalai. svn:r1448 | |
|
25af6954 | 2009-10-14 00:46:47 | When a bufferevent_connect() call fails, give the client an error callback. Patch from Christopher Davis. svn:r1444 | |
|
fc83ca3c | 2009-10-14 00:46:40 | Fix some crash bugs when initializing evdns svn:r1443 | |
|
633f3fb7 | 2009-10-02 03:07:29 | Add changelog for last commit svn:r1440 | |
|
d5b640fc | 2009-10-01 15:29:08 | Apply Ka-Hing Cheung's event_base_got_[break|exit] patch, with locking and whitespace fixes. svn:r1438 | |
|
8e8d94a3 | 2009-09-24 22:18:19 | Do not drop data from evbuffer when out of memory; reported by Jacek Masiulaniec svn:r1436 | |
|
18fe4008 | 2009-09-23 23:51:26 | Forward-port: fix android compilation svn:r1435 | |
|
c2ead9f1 | 2009-09-11 21:02:19 | Treat events with fd == -1 as addable. This turns out to simplify a fair bit of logic, including the bufferevent code, and should fix bug 2850656. svn:r1431 | |
|
85255a63 | 2009-09-11 18:47:35 | Make epoll use less RAM. We do this by not allocating the maximum epoll_event array for the epoll backend at startup. Instead, we start out accepting 32 events at a time, and double the array's size when it seems that the OS is generating events faster than we're requesting them. This saves up to 374K per epoll-based event_base. Resolves bug 2839240. svn:r1428 | |
|
e3f89fa2 | 2009-09-11 18:21:57 | Add a trivial race-fix from Chromium: do not try to re-detect whether we have a monotonic clock every time we make a new event_base. svn:r1427 | |
|
3b461a6d | 2009-09-11 18:21:37 | Treat a negative number of bytes to read as the kernel saying "I don't know." svn:r1426 | |
|
f65b8b09 | 2009-08-19 20:55:25 | On connect, call only one of BEV_EVENT_CONNECTED or writecb. Previously, if we had a socket bufferevent in connect state, we'd send both of these to indicate that the connection was done. That was broken since the point of adding BEV_EVENT_CONNECTED was so that we could distinguish "we're connected" and "we wrote something". Now, writecb is called only when A) the connection finished but the user never put the socket into a "connecting" state, or B) data was actually written. svn:r1425 | |
|
2c1b0e44 | 2009-08-16 19:22:15 | Fix build warnings and add changelog entry for evhttp patches. svn:r1424 | |
|
22bd5b42 | 2009-08-16 16:40:42 | Support sendfile on solaris: patch from Caitlin Mercer. svn:r1419 | |
|
7a55c48d | 2009-08-09 20:18:00 | Add a few missing changelog entries svn:r1412 | |
|
d4134772 | 2009-07-31 17:35:42 | Refactor evbuffer_readln() into a search-for-eol function and an extract-line function. svn:r1404 | |
|
7c688dd9 | 2009-07-31 14:41:45 | New function to expose bufferevent.enabled svn:r1401 | |
|
621aafd2 | 2009-07-30 22:11:23 | Export sockaddr comparison functionality. svn:r1400 | |
|
d1a2254b | 2009-07-30 20:41:31 | Fix some bugs in bufferevent_socket_connect svn:r1398 | |
|
7c20a6ae | 2009-07-30 17:01:21 | Export an ev_socklen_t. svn:r1391 | |
|
75fe762e | 2009-07-30 17:00:56 | Accessor function to get a listener's associated fd svn:r1390 | |
|
3c99c79d | 2009-07-28 19:45:54 | Changelog entry for msvc fixes. svn:r1388 | |
|
72ea534f | 2009-07-28 19:41:57 | Export evutil_str[n]casecmp as evutil_ascii_str[n]casecmp. svn:r1387 | |
|
12199fa7 | 2009-07-28 17:11:03 | Fix segfault during failed allocatino of locked evdns base. We need to comb the rest of the code to make sure that we don't blindly wrap functions in LOCK(x), UNLOCK(x) when those functions might contain a FREE(x) in the middle. Rocco Carbone found and reported this bug. svn:r1384 | |
|
f8b527e6 | 2009-07-28 05:09:06 | Fix a dumb bug where we would allocate too little memory in event_get_supported_methods(). svn:r1383 | |
|
709c21c4 | 2009-07-28 04:03:57 | Bufferevent support for openssl. This code adds a new Bufferevent type that is only compiled when the openssl library is present. It supports using an SSL object and an event alert mechanism, which can either be an fd or an underlying bufferevent. There is still more work to do: the unit tests are incomplete, and we need to support flush and shutdown much better. Sometimes events are generated needlessly: this will hose performance. There's a new encrypting proxy in sample/le-proxy.c. This code has only been tested on OSX, and nowhere else. svn:r1382 | |
|
e8400a43 | 2009-07-20 14:55:35 | Rename encode_int(64) to avoid polluting the global namespace. They're now called evtag_encode_int(64). The old names are available as macros in event2/tag_compat.h. Also, add unit tests for encode/decode_int64. svn:r1365 | |
|
9fcd84d1 | 2009-07-14 19:19:45 | Include disabled methods in event_get_supported_methods() output. Previously, events that were disabled using EVENT_NO* were left out of event_get_supported_methods(). This was wrong, broke unit tests (under some circumstances) and left the user with no good way to tell which methods were actually compiled in. Fixes bug 2821015. svn:r1344 | |
|
6b4b77a2 | 2009-07-14 16:54:48 | Make event_del(E) block while E is running in another thread. This gives you the property that once you have called event_del(E), you know that E is no longer running or pending or active at all, and so it is safe to delete the resource used by E's callback. svn:r1341 | |
|
d3a8ccb8 | 2009-07-10 19:38:16 | Change use of AC_CHECK_LIB to AC_SEARCH_LIBS. Patch from Zack Weinberg. His message: This one eliminates all use of AC_CHECK_LIB in the configure script. AC_CHECK_LIB has a serious flaw: if the library you mention *exists* but is not *necessary* for the function you want, it adds it to $(LIBS) anyway. This was fine in the days of static libraries, because the linker would ignore an .a library that didn't contain anything you needed. However, ELF shared libraries are different (let's not get into why): the linker will by default record a DT_NEEDED entry for every shared object mentioned on the link command line. Thus, every use of AC_CHECK_LIB is a potential unnecessary DT_NEEDED, making extra work for the dynamic loader. The cure is simply to use AC_SEARCH_LIBS instead; it first tries to find the function you ask for in libc, and only if that doesn't work does it try to use the extra library you mention. For the same reasons, pkg-config .pc files should distinguish between the libraries to use for shared linkage (Libs:) and the additional libraries needed for static linkage (Libs.private:). I have also made that correction in this patch. I also took the opportunity to clean up the substitution variables a little and make absolutely sure that the core library does not get linked against zlib. svn:r1338 | |
|
a501d683 | 2009-07-10 19:34:00 | Add a lock/unlock pair inside the event callbacks in bufferevents. This fixes part of bug 2800642, I believe, though there is still a general race condition in multithreaded use of events that we need to think about. svn:r1337 | |
|
6469598e | 2009-07-03 17:43:26 | Allow C identifiers as struct names; allow multiple comments in .rpc files; from Zack Weinberg; plus a tiny tweak svn:r1336 | |
|
fbb181d1 | 2009-07-03 17:31:17 | Allow specifying the output filename for rpcgen; based on work by jmansion; patch from Zack Weinberg. svn:r1335 | |
|
bbcc54ef | 2009-07-03 17:25:45 | fix preamble of rpcgen-generated files to rely on event2 includes; based on work by jmansion; patch from Zack Weinberg. svn:r1334 | |
|
37d3e16c | 2009-07-03 17:20:56 | Raise RpcGenError in event_rpcgen.py; from jmanison and Zack Weinberg svn:r1333 | |
|
342ad355 | 2009-06-30 14:23:18 | The truncated bit is in the 3rd byte of a dns reply, not the 4th. [fwd-port] svn:r1332 | |
|
d1ffba1d | 2009-06-05 19:52:13 | Replace some read/write instances with send/recv to work properly on win32. svn:r1324 | |
|
cdaca02c | 2009-05-27 15:35:00 | Activate fd events in a pseudorandom order on older backends. New backends like poll and kqueue and so on add fds to the queue in the order that they are triggered. But the select backend currently activates low-numbered fds first, whereas the poll and win32 backends currently favor whatever fds have been on for the longest. This is no good for fairness. svn:r1318 | |
|
8c66eb2e | 2009-05-22 14:48:40 | Try to contain the failure when we are running without socketpair(). Some win32 systems (mostly those using Kaspersky, it would seem) prevent us from faking socketpair(). This makes our signal notification code just not work. Our response since 1.4 has been to assert. For users who would rather work without signals than not work at all, this has been a regression from 1.3e. This patch makes adding signal events fail in this case; there's no reason to kill the whole process. svn:r1303 | |
|
59cd4936 | 2009-05-22 14:31:07 | Do not free the event base lock until we are done removing all the events. Spotted by Joachim Bauch; fixes bug 2795402. svn:r1302 | |
|
59484297 | 2009-05-20 12:24:13 | Fix a deadlock: there were some LOCKs that should have been UNLOCKs. Resolves bug 2794244 svn:r1298 | |
|
66df9daf | 2009-05-19 21:49:53 | Add changelog for last commit svn:r1297 | |
|
dc4c7b95 | 2009-05-15 22:44:18 | Change the interface of evbuffer_add_reference: give the cleanup function more info. svn:r1294 | |
|
bba69e03 | 2009-05-15 20:23:59 | New semantics for evbuffer_cb_set_flags(). Previously, set_flags() would replace all previous user-visible flags. Now it just sets the flags, and there is a clear_flags() function to clear other flags. svn:r1293 | |
|
b4886ec8 | 2009-05-15 18:44:44 | Trim 22 bytes from struct event on 32 bit platforms, more on 64-bit platforms. svn:r1292 | |
|
31d89f27 | 2009-05-13 20:37:21 | Add a "ctrl" mechanism to bufferevents for property access. OpenSSL uses something like this to implement get/set access for properties on its BIOs, so that it doesn't need to add a pair of get/set functions to the vtable struct for every new abstract property it provides an accessor for. Doing this lets us make bufferevent_setfd abstract, and implement an abstract bufferevent_getfd. svn:r1284 | |
|
83f46e51 | 2009-05-13 20:36:56 | Do not use the "evbuffer_" prefix to denote parts of bufferevents. This is a bit of an interface doozy, but it's really needed in order to be able to document this stuff without apologizing it. This patch does the following renamings: evbuffercb -> bufferevent_data_cb everrorcb -> bufferevent_event_cb EVBUFFER_(READ,WRITE,...) -> BEV_EVENT_(...) EVBUFFER_(INPUT,OUTPUT) -> bufferevent_get_(input,output) All the old names are available in event2/bufferevent_compat.h svn:r1283 | |
|
f11dff2c | 2009-05-07 03:45:51 | Add and use locale-independent strcasecmp functions. svn:r1280 | |
|
659d54d5 | 2009-05-05 02:59:26 | Add new code to make and accept connections. This is stuff that it's easy to get wrong (as I noticed when writing bench_http), and that takes up a fair amount of space (see http.c). Also, it's something that we'll eventually want to abstract to use IOCP, where available. svn:r1272 | |
|
0fd70978 | 2009-05-05 01:09:03 | Add an event_get_base() function to remove one more reason to include event_struct.h svn:r1271 | |
|
0e63e72a | 2009-05-03 18:56:08 | Nothing ever sets event_sigcb or event_gotsig any more: remove them. svn:r1270 | |
|
d5ca0763 | 2009-05-02 16:23:29 | Move event_set() and friends to event2/event_compat.h. These functions are deprecated in favor of event_assign(). svn:r1267 | |
|
a109d95c | 2009-05-02 16:11:06 | Add changelog entry for vc++ fixes svn:r1264 | |
|
2ebfd3ba | 2009-04-28 19:08:17 | Oops. We never actually defined event_config_set_flag(). svn:r1246 | |
|
b228ff91 | 2009-04-25 00:15:31 | remove vararg macros for accessing evrpc structs svn:r1243 | |
|
5c4c13d8 | 2009-04-24 03:24:22 | make sendfile work on freebsd svn:r1239 | |
|
a5897917 | 2009-04-23 21:43:44 | Changelog entry for r1237 svn:r1238 | |
|
faa756c7 | 2009-04-23 21:34:37 | Oops. event_config.flags was never initialized. Bugfix on 2.0.1-alpha. Found by Victor Goya. svn:r1236 | |
|
9516df0e | 2009-04-23 05:40:06 | Fix c89 bugs reported by Cory Stup. Others may remain. I wasn't able to get gcc --std=c89 to build libevent at all, so I don't know what compiler the original reporter is using here. Note that this change requires us to disable the part of our rpc code that uses variadic macros when using a non-gcc compiler. This is a problem if we want our rpc api to be portable. svn:r1231 | |
|
df0617f2 | 2009-04-23 00:21:23 | Use signal.h, not sys/signal.h. This is patch 2673214 from mmadia. It is correct, since we unconditionally include signal.h in many other places, and only sometimes include sys/signal.h. It is necessary to compile on Haiku, I'm told. svn:r1228 | |
|
8b7a3b36 | 2009-04-23 00:01:24 | Fix min_heap_erase when we remove an element from the middle of the heap. Previously, we could lose the heap property when we removed an item whose parent was greater than the last element in the heap. We would replace the removed item with the last element, and consider shifting it down, but we wouldn't consider shifting it up. Patch from Marko Kreen. svn:r1226 | |
|
253151c5 | 2009-04-22 20:28:30 | Detect and reject n_priorities less than 1. svn:r1222 | |
|
01bda2b8 | 2009-04-22 20:27:21 | Add forgotten changelog. svn:r1221 | |
|
d3fbe7fa | 2009-04-21 18:47:53 | Do not free the signal index unless it was at some point allocated svn:r1217 | |
|
b7907a7b | 2009-04-19 01:59:25 | Note dns work in changelog and whatsnew svn:r1206 | |
|
a98a512b | 2009-04-17 23:12:34 | Add a generic way for any bufferevent to make its callback deferred svn:r1197 | |
|
e3d82497 | 2009-04-10 14:21:53 | Don't allow internal events to starve lower-priority events. This is exceptionally important with multithreaded stuff, where we use an event to notify the base that other events have been made active. If the activated events have a prioirty number greater than that of the notification event, it will starve them, and that's no good. svn:r1149 | |
|
ce146eb1 | 2009-04-10 05:43:45 | Fix parsing of queries where the encoded queries contained \r, \n or + svn:r1148 | |
|
72b6ffe8 | 2009-04-08 03:05:42 | Prevent unsupported modifications to bufferevent_sock buffers. In particular, we don't allow adding any data to end front of inbuf (we do that when we read), or removing it from the front of outbuf (we drain data only when we write). svn:r1144 | |
|
747331d1 | 2009-04-08 03:04:39 | Add freeze support to evbuffers. From the documentation: Prevent calls that modify an evbuffer from succeeding. A buffer may frozen at the front, at the back, or at both the front and the back. If the front of a buffer is frozen, operations that drain data from the front of the buffer, or that prepend data to the buffer, will fail until it is unfrozen. If the back a buffer is frozen, operations that append data from the buffer will fail until it is unfrozen. We'll use this to ensure correctness on an evbuffer when we're waiting for an overlapped IO call to finish. svn:r1143 | |
|
77c80b8d | 2009-02-11 17:24:11 | New bind-to option to allow DNS clients to bind to arbitrary ports for their outgoing addresses. svn:r1119 | |
|
c7b2f8fd | 2009-02-10 19:38:05 | New function to abstract SO_REUSEADDR. svn:r1102 | |
|
fdf69493 | 2009-01-27 06:05:38 | sendfile/mmap and memory reference implementation for evbuffers svn:r1057 | |
|
56ea4687 | 2009-01-22 02:33:38 | Change the semantics of timeouts in conjunction with EV_PERSIST; timeouts in that case will now repeat until deleted. svn:r1032 | |
|
309fc7c4 | 2009-01-21 07:51:25 | New functions to provide sane threading callbacks with pthreads and win32 threading implementations. svn:r1031 | |
|
f6eb1f81 | 2009-01-19 21:53:03 | Change evbuffer_read implementation to split data across chunks, and use readv when available. This should make us use less space. svn:r1024 | |
|
a5901991 | 2009-01-19 20:37:24 | Use eventfd for main-thread notification where available (i.e., linux). svn:r1023 | |
|
99db0e7f | 2009-01-12 20:42:19 | Add a new evbuffer_write_atmost() functino to write no more than a given number of bytes to an fd. svn:r993 | |
|
135591ae | 2009-01-02 20:46:35 | Change the type of nameserver.address from u32 to sockaddr_storage, so that we can handle nameservers at IPv6 addresses. svn:r985 | |
|
0d9d5cfe | 2009-01-02 20:46:12 | New functions in evutil to clone inet_pton and inet_ntop, with tests. Adapted from Tor code. svn:r983 | |
|
02b2b4d1 | 2008-12-23 16:37:01 | Restructure the event backends so that they do not need to keep track of events themselves, as a side effect multiple events can use the same fd or signal. svn:r972 | |
|

de069b99 | 2008-09-05 16:29:56 | On win32, errno is not the last socket error. Worse, WSAGetLastError() is not the last socket error sometimes (i.e., EWOULDBLOCK). Also, strerror() does not handle winsock errors. Therefore, event_err() and event_warn() are completely wrong for windows socket errors. Fix that. svn:r936 | |
