Azat Khuzhin 85a0ec9b 2024-05-06T08:50:36 be: make the code in bufferevent_socket_connect() more reliable There is one icky in case for windows: if (sa) { #ifdef _WIN32 if (bufferevent_async_can_connect_(bev)) { bufferevent_setfd(bev, fd); r = bufferevent_async_connect_(bev, fd, sa, socklen); if (r < 0) goto freesock; bufev_p->connecting = 1; result = 0; goto done; - } else + } else { #endif r = evutil_socket_connect_(&fd, sa, socklen); if (r < 0) // Previosly this line was executed // regardless of bufferevent_async_can_connect_(), but the case under // bufferevent_async_can_connect_() always does goto, so it is 100% the // same code, but just to make it more cleaner goto freesock; +#ifdef _WIN32 + } +#endif }
Azat Khuzhin 3201009b 2024-05-06T08:38:53 Revert "Remove dead code from bufferevent_socket_connect" That wasn't the dead code, since the `r` could be `2` in case of `ECONNREFUSED`, and it should trigger errorcb not the writecb. This is actually questionable should be call errorcb at all in case of connect() returns an error immediately, but I guess the reason was to make it compatible with others, ECONNREFUSED can be returned only for specific cases and only on BSD (AFAIK). While for instance EHOSTUNREACH is not. And after this change now all tests are passed on FreeBSD. Well, sometimes few tests fails due to timing issues, but in general looks good. Since even all tests in parallel passed: $ rm -f /tmp/libevent*log; bin/regress --list-tests | awk '/^ / { print $1 }' | xargs -I{} -P100 bash -c 'n={}; bin/regress --no-fork --verbose $n |& tee /tmp/libevent-test-${n//\//_}.log' |& grep -F ' [FAILED' |& tee /tmp/libevent-tests.log And having green CI is crucial for libevent, not only because it is a rule of thumb for all projects, but also because in case of failures it will retry on and on, which will cause CI stuck.

Joseph Spadavecchia 5e137f37 2014-12-08T17:32:07 Implement bufferevent_socket_connect_hostname_hints() So that ai_flags (such as AI_ADDRCONFIG) can be specified. Closes: #193 (cherry-picked with conflicts resolved)
Azat Khuzhin b29207dc 2019-01-29T21:12:33 Eliminate fd conversion warnings and introduce EVUTIL_INVALID_SOCKET (windows) windows has intptr_t instead of regular int. Also tt_fd_op() had been introduced, since we cannot use tt_int_op() for comparing fd, since it is not always int.

Jesse Fang f7bc1337 2018-02-23T19:15:12 bufferevent_socket_connect{,_hostname}() missing event callback and use ret code - When socket() failed in bufferevent_socket_connect() , the event callback should be called also in bufferevent_socket_connect_hostname(). eg. when use bufferevent_socket_connect_hostname() to resolve and connect an IP address but process have a smaller ulimit open files, socket() fails always but caller is not notified. - Make bufferevent_socket_connect()'s behavior more consistent: function return error then no callback, function return ok then error passed by event callback.

Azat Khuzhin a10a6f4e 2017-08-14T23:11:53 Remove check against passed bufferevent in bufferevent_socket_connect() It is a bit confusing to check against the result of EVUTIL_UPCAST(), because it can return not NULL for NULL pointers, but for even though with bufferevent we are fine (because bufferevent is the first field in bufferevent_private), there are no checks for "bufev" in bufferevent's API, so just remove it to make it generic.

Azat Khuzhin 9a0a3a3e 2017-01-16T02:31:54 be: fix with filtered bufferevents and connect() without EAGAIN With filtered bufferevents (i.e. not real one, that have socket), we can trigger incorrect callback in this case. Let's look at example with http and bufferevent_openssl_filter_new(): - bev = bufferevent_openssl_filter_new() - http layer trying to connect() to localhost with bev # at this time, bev have writecb/readcb NULL but ev_write/ev_read has # timeout with 45 secs, default HTTP connect timeout - and when connect() retruns without EAGAIN (BSD'ism) we called event_active() before (with EV_WRITE), and this will call ev_write timeout only, while it is more correct to act on bufferevent instead of plain event, so let's trigger EV_WRITE for bufferevent which will do the job (and let's do this deferred). Fixes: http/https_simple # under solaris
Azat Khuzhin 3189eb00 2016-08-10T16:04:33 be_sock: handle readv() returns ECONNREFUSED (freebsd 9.2) During testing sometimes bufferevent/bufferevent_connect_fail_eventcb fails, and after some digging I found that this was the case when connect() doesn't return ECONNREFUSED immediately, and instead next operation will return it (in our case evbuffer_read()->readv(), needless to say that after this bufferevent_writecb() called and it checks error with getsockopt() but of course it doesn't return any error), so this patch checks "errno" after "readv()" and installs "bufev::connection_refused" flag, to handle this from writecb and only once.

Azat Khuzhin 86dfd2ce 2016-03-21T17:09:17 be_sock: cancel in-progress dns requests Before this patch we didn't have such functionality and this can cause some issues when we are cancelling HTTP request while after this we will get a response/timeout from the NS and in this case error_cb will be called and can damage newly started HTTP request. We could also have problems with connect, but we don't have them since we closes the fd in HTTP layer. This is not so good that this is done in be_sock, but it is internal, so we can change without pain. Plus I don't like that callback-via-evutil, but since we have event_extra we need do like that. And after this patch the following tests doesn't report leaks: $ valgrind --leak-check=full --show-reachable=yes --track-fds=yes --error-exitcode=1 regress --no-fork http/cancel.. ... ==10469== FILE DESCRIPTORS: 2309 open at exit. ... ==10469== HEAP SUMMARY: ==10469== in use at exit: 0 bytes in 0 blocks ==10469== total heap usage: 33,846 allocs, 33,846 frees, 4,617,651 bytes allocated ==10469== ==10469== All heap blocks were freed -- no leaks are possible v2: do under lock v3: reset dns request v4: ignore EVUTIL_EAI_CANCEL in regular callback

Azat Khuzhin 8bb38425 2014-11-15T21:46:11 bufferevent: move conn_address out from http into bufferevent In http the only case when when we could store it is when we already connected, *but* if we are doing request using domain name, then we need to do request to nameserver to get IP address, and this is handled by bufferevent. So when we have IP address (from nameserver) and don't have connection to this IP address, we could already cache it to avoid extra DNS requests (since UDP is slow), and we can't do this from http layer, only from bufferevent.

Nick Mathewson 02fbf687 2013-04-09T18:16:13 Use finalization feature so bufferevents can avoid deadlocks Since the bufferevents' events are now EV_FINALIZE (name pending), they won't deadlock. To clean up properly, though, we must use the finalization feature. This patch also split bufferevent deallocation into an "unlink" step that happens fast, and a "destruct" step that happens after finalization. More work is needed: there needs to be a way to specify a finalizer for the bufferevent's argument itself. Also, this finalizer business makes lots of the reference counting we were doing unnecessary. Also, more testing is needed.

Nick Mathewson c0e425ab 2012-05-09T11:06:06 Restore our priority-inversion-prevention code with deferreds Back when deferred_cb stuff had its own queue, the queue was always executed, but we never ran more than 16 callbacks per iteration. That made for two problems: 1: Because deferred_cb stuff would always run, and had no priority, it could cause priority inversion. 2: It doesn't respect the max_dispatch_interval code. Then, when I refactored deferred_cb to be a special case of event_callback, that solved the above issues, but made for two more issues: 3: Because deferred_cb stuff would always get the default priority, it could could low-priority bufferevents to get too much priority. 4: With code like bufferevent_pair, it's easy to get into a situation where two deferreds keep adding one another, preventing the event loop from ever actually scanning for more events. This commit fixes the above by giving deferreds a better notion of priorities, and by limiting the number of deferreds that can be added to the _current_ loop iteration's active queues. (Extra deferreds are put into the active_later state.) That isn't an all-purpose priority inversion solution, of course: for that, you may need to mess around with max_dispatch_interval.
Nick Mathewson 8ac3c4c2 2012-02-29T15:07:33 Have all visible internal function names end with an underscore. We haven't had a convention for naming internal functions in -internal.h versus naming visible functions in include/**.h. This patch changes every function declared in a -internal.h file to be named ending with an underscore. Static function names are unaffected, since there's no risk of calling them from outside Libevent. This is an automatic conversion.

Nick Mathewson 68120d9b 2012-02-29T15:07:31 Convert event-config.h macros to avoid reserved identifiers C reserves all identifiers beginning with an underscore for system use. But we had been mangling our autoconf identifiers with the prefix "_EVENT_" to avoid conflict with other programs. Instead, we will now use the prefix "EVENT__". With any luck, the double-underscore will still hint "here be dragons" to anybody tempted to think that event-config.h is a stable api. This is an automatically generated patch. The script that produced it was made by running this script over config.h.in: ===== #!/usr/bin/perl -w # Run this on config.h.in use strict; my %macros = (); while (<>) { if (/^# *undef +([A-Za-z0-9_]+)/) { $macros{$1} = 1; } } print "#!/usr/bin/perl -w -i -p\n\n"; for my $k (sort keys %macros) { print "s/(?<![A-Za-z0-9_])_EVENT_$k(?![A-Za-z0-9_])/EVENT__$k/g;\n"; } == And the script that it generated was then run over all .c and .h files: #!/usr/bin/perl -w -i -p s/(?<![A-Za-z0-9_])_EVENT_DISABLE_DEBUG_MODE(?![A-Za-z0-9_])/EVENT__DISABLE_DEBUG_MODE/g;

Nick Mathewson 0ba0af9c 2011-09-29T09:30:04 Prefer mmap to sendfile unless a DRAINS_TO_FD flag is set. Allows add_file to work with SSL. The sendfile() implementation for evbuffer_add_file is potentially more efficient, but it has a problem: you can only use it to send bytes over a socket using sendfile(). If you are writing bytes via SSL_send() or via a filter, or if you need to be able to inspect your buffer, it doesn't work. As an easy fix, this patch disables the sendfile-based implementation of evbuffer_add_file on an evbuffer unless the user sets a new EVBUFFER_FLAG_DRAINS_TO_FD flag on that evbuffer, indicating that the evbuffer will not be inspected, but only written out via evbuffer_write(), evbuffer_write_atmost(), or drained with stuff like evbuffer_drain() or evbuffer_add_buffer(). This flag is off by default, except for evbuffers used for output on bufferevent_socket. In the future, it could be interesting to make a best-effort file segment implementation that tries to send via sendfile, but mmaps on demand. That's too much complexity for a stable release series, though.

We might as well turn it into a function: an extra function call is going to be cheap in comparison with the system call.

Nick Mathewson 57b72488 2010-02-27T22:27:13 Small cleanups on freebsd-connect-refused patch. There should be no need to call be_socket_enable: that does an event_add(). What we really want to do is event_active(), to make sure that the writecb is executed. Also, there was one "} if () {" that was missing an else. I've noted that the return value for evutil_socket_connect() is getting screwy, but since that isn't an exported function, we can fix it whenever.

Nick Mathewson d3288293 2010-02-20T18:44:35 Provide consistent, tested semantics for bufferevent timeouts The different bufferevent implementations had different behavior for their timeouts. Some of them kept re-triggering the timeouts indefinitely; some disabled the event immediately the first time a timeout triggered. Some of them made the timeouts only count when the bufferevent was actively trying to read or write; some did not. The new behavior is modeled after old socket bufferevents, since they were here first and their behavior is relatively sane. Basically, each timeout disables the bufferevent's corresponding read or write operation when it fires. Timeouts are stopped whenever we suspend writing or reading, and reset whenever we unsuspend writing or reading. Calling bufferevent_enable resets a timeout, as does changing the timeout value.
Nick Mathewson db08f640 2010-02-20T12:55:59 Suspend read/write on bufferevents during hostname lookup When we're doing a lookup in preparation for doing a connect, we might have an unconnected socket on hand, and mustn't actually do any reading or writing with it.

Nick Mathewson ff3f6cd4 2010-01-22T16:14:49 Check more internal event_add() calls for failure Most of these should be unable to fail, since adding a timeout generally always works. Still, it's better not to try to be "too smart for our own good here." There are some remaining event_add() calls that I didn't add checks for; I've marked those with "XXXX" comments.

Nick Mathewson 2e8eeea3 2009-12-29T19:50:03 Fix crash bugs when a bufferevent's eventcb is not set. In many places throughout the code, we called _bufferevent_run_eventcb without checking whether the eventcb was actually set. This would work fine when the bufferevent's callbacks were deferred, but otherwise the code would segfault. Strangely, we always remembered to check before calling the _bufferevent_run_{read,write}cb functions. To prevent similar errors in the future, all of _buferevent_run_{read,write,event}cb now check to make sure the callback is actually set before invoking or deferring the callback. This patch also removes the now-redundant checks for {read,write}cb.
Nick Mathewson 82743794 2009-12-24T17:47:14 Do not make bufferevent_setfd implicitly disable EV_READ and EV_WRITE. This obviates the need for BEV_SUSPEND_CONNECTING, and good riddance.
Nick Mathewson 737c9cd8 2009-11-27T13:16:54 Rate-limiting for bufferevents; group and individual limits are supported.

Nick Mathewson 4a5b5343 2009-12-23T07:48:43 Do not ignore bufferevent_enable(EV_READ) before bufferevent_connect(). Previously, we weren't remembering that we wanted to re-add the read event once the connect was finished. Now we are.
Nick Mathewson cf749e22 2009-11-18T21:16:53 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
Nick Mathewson d7d1f1da 2009-11-17T20:31:09 Move responsibility for IOCP callback into bufferevent_async.

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

This function is meant to eventually replace the hostname resolution mess in http.c. svn:r1496

Nick Mathewson f65b8b09 2009-08-19T20:55:25 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

Nick Mathewson 709c21c4 2009-07-28T04:03:57 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
Nick Mathewson a62283a9 2009-07-17T17:46:17 Always hold a reference to a bufferevent when calling its callbacks. Rationale: we hold a lock on the bufferevent when its callbacks are executing, so we need to release the lock afterwards. But the callback might free the bufferevent, so unless we're holding a reference on the bufferevent, the lock might not be there for us to release. svn:r1347
