b5ca3656 2016-05-30 16:53:41 For non GCC/clang on OSX the -Wno-deprecated-declarations may not be valid Closes: nmathewson/Libevent#129
41e54464 2016-05-12 00:40:25 Merge branch 'travis-ci-os-matrix-v2' This increases libevent coverage to: - os:osx - cmake -DEVENT__DISABLE_MM_REPLACEMENT=ON - cmake -DEVENT__ENABLE_VERBOSE_DEBUG=ON - configure --disable-openssl - configure --disable-thread-support - configure --disable-malloc-replacement - fix travis-ci builds under automake >1.11 Possible failures after this patch set (not always, IOW in some builds this issues aren't real issues): - some failures but mostly because of timing issues, must be fixed separately. - https://travis-ci.org/azat/libevent/jobs/129430229 # on brew update - https://travis-ci.org/azat/libevent/jobs/129430221 # some locking issues * travis-ci-os-matrix-v2: automake: define serial-tests only if automake have this option test/automake: don't use paralell test harness (since automake 1.12) travis-ci/osx: relink gcc/g++ instead of clang travis-ci: enable multi-os mode (osx, linux) travis-ci: increase matrix (--disable-foo) travis-ci: adjust alignment Fixes: #356 Travis-CI: https://travis-ci.org/azat/libevent/builds/129430181
61179dec 2016-05-11 16:02:02 automake: define serial-tests only if automake have this option P.S. I did try a lot of other ways, but seems that this is the only one that will work. Fixes: automake 1.11 Travis-CI: https://travis-ci.org/azat/libevent/jobs/129398265
44d755e0 2016-05-11 10:18:25 test/automake: don't use paralell test harness (since automake 1.12) Starting from automake 1.2 there is parallel test harness, that redirects all output to some log, which serial-test doesn't do. So in case of new runner we can get no output for 10 minutes, for example on my desktop: $ time make verify VERBOSE=1 PASS: test/test-script.sh ============================================================================ Testsuite summary for libevent 2.1.5-beta ============================================================================ # TOTAL: 1 # PASS: 1 # SKIP: 0 # XFAIL: 0 # FAIL: 0 # XPASS: 0 # ERROR: 0 ============================================================================ real 25m31.735s user 0m13.753s sys 0m7.648s And this means that this will fail on travis-ci, since it has timeout for 10 minutes. Sure we can use `travis wait 60` instead, but I think that it is better to fix this by writing result to output, instead of hacking around, so let's use serial-tests instead of parallel always. And now it works on travis-ci under linux because it has automake 1.11 while osx has at least 1.12. Links: https://docs.travis-ci.com/user/common-build-problems/ https://www.gnu.org/software/automake/manual/html_node/Serial-Test-Harness.html#Serial-Test-Harness https://www.gnu.org/software/automake/manual/html_node/Parallel-Test-Harness.html CI: https://travis-ci.org/azat/libevent/jobs/129171497 # ok on linux https://travis-ci.org/azat/libevent/jobs/129171532 # no output for 10 min on osx
481481d3 2016-05-10 10:25:05 travis-ci/osx: relink gcc/g++ instead of clang Since by default osx replaces /usr/bin/gcc with it's apple clang, while we have gcc in our build matrix, so use real gcc.
79917e48 2016-05-09 18:14:31 travis-ci: enable multi-os mode (osx, linux) - use addons.apt.packages instead of `apt-get install` - add `brew update`/`brew install ...` Link: https://docs.travis-ci.com/user/installing-dependencies/ Link: https://docs.travis-ci.com/user/multi-os/
59649f74 2016-05-09 18:48:56 travis-ci: increase matrix (--disable-foo) Use --disable-foo from https://github.com/libevent/libevent/wiki/ReleaseChecklist

b59ef3bd 2016-03-29 19:20:30 Merge remote-tracking branch 'origin/pr/339' * origin/pr/339: evbuffer_add: Use last_with_datap if set, not last. test/regress: add tests for evbuffer_add() breakage on empty last chain Fixes: #335
a8769ef1 2016-03-26 20:11:43 evbuffer_add: Use last_with_datap if set, not last. evbuffer_add() would always put data in the last chain, even if there was available space in a previous chain, and in doing so it also failed to update last_with_datap, causing subsequent calls to other functions that do look at last_with_datap to add data in the middle of the evbuffer instead of at the end. Fixes the evbuffer_add() part of issue #335, and the evbuffer/add2 and evbuffer/add3 tests, and also prevents wasting space available in the chain pointed to by last_with_datap.
d5ee7391 2016-03-26 14:14:44 test/regress: add tests for evbuffer_add() breakage on empty last chain The evbuffer/add* tests currenly break on 2.0.21, 2.0.22 and 2.1 HEAD due to issue #335. The evbuffer/reference2 test breaks on 2.0.21 and 2.0.22 due to commit b18c04dd not being applied.

ec65c420 2016-03-25 00:33:47 evdns: fix searching empty hostnames From #332: Here follows a bug report by **Guido Vranken** via the _Tor bug bounty program_. Please credit Guido accordingly. ## Bug report The DNS code of Libevent contains this rather obvious OOB read: ```c static char * search_make_new(const struct search_state *const state, int n, const char *const base_name) { const size_t base_len = strlen(base_name); const char need_to_append_dot = base_name[base_len - 1] == '.' ? 0 : 1; ``` If the length of ```base_name``` is 0, then line 3125 reads 1 byte before the buffer. This will trigger a crash on ASAN-protected builds. To reproduce: Build libevent with ASAN: ``` $ CFLAGS='-fomit-frame-pointer -fsanitize=address' ./configure && make -j4 ``` Put the attached ```resolv.conf``` and ```poc.c``` in the source directory and then do: ``` $ gcc -fsanitize=address -fomit-frame-pointer poc.c .libs/libevent.a $ ./a.out ================================================================= ==22201== ERROR: AddressSanitizer: heap-buffer-overflow on address 0x60060000efdf at pc 0x4429da bp 0x7ffe1ed47300 sp 0x7ffe1ed472f8 READ of size 1 at 0x60060000efdf thread T0 ``` P.S. we can add a check earlier, but since this is very uncommon, I didn't add it.

86dfd2ce 2016-03-21 17:09:17 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

Also extra check for EVHTTP_CON_PUBLIC_FLAGS_END, in case somebody forgot about this (implementer I mean). Refs: #182

088d8b39 2015-12-27 02:31:03 test/regress: main/fork: rewrite assertions by just removing event in callback Instead of assigning some variable value (got_child), and schedule exit from loop from that callback, just remove event for that signal, and event loop will exit automatically when there will be no events.
88640aa1 2015-12-27 02:15:03 event_reinit: make signals works after fork() without evsig_add() event_reinit() removes the event, but only evsig_add puts it back. So any signals set up before event_reinit will be ignored until another signal is added. Fixes: #307
ad0c237b 2015-12-27 01:43:37 event_reinit: always re-init signal's socketpair Before this patch event_reinit() only closes the signal socketpair fds and recreates them if signals have been added, but this is wrong, since socketpair fds created on backend init, and if we will not re-create them bad things in child/parent signal handling will happens (and indeed this is what happens for non-reinit backends like select).
