This matches their use throughout the rest of the project, and fixes the
build when you are cross-compiling on Linux using mingw-w64. i.e:
CC epoll.lo
CC wepoll.lo
CC signal.lo

In some CMake integrations, portions of the toolchain may end up
defining CMAKE_USE_PTHREADS_INIT even when EVENT__DISABLE_THREAD_SUPPORT
is set for libevent. Modify the build to not rely on this side effect
of find_package(Threads, ...) [which could be done elsewhere] but instead
to use EVENT__HAVE_PTHREADS which is defined only on the desired codepath.
Without this change, affected builds fail as a result of event_pthreads source
files being built but with build defines which cause the build to fail.

Added new option `edns-udp-size` for evdns_base which allows
to control maximum allowed size of UDP DNS messages. This
maximum size is passed to the DNS server via edns mechanism.
@jcoffland:
"When the max connection limit is enabled and the limit is reached, the
server will respond immediately with 503 Service Unavailable. This can
be used to prevent servers from running out of file descriptors. This is
better than request limiting because clients may make more than one
request over a single connection. Blocking a request does not
necessarily close the connection and free up a socket."
* http-max_connections-pr-592:
test: cover evhttp max connections
Added evhttp max simultaneous connection limiting
@seleznevae:
"Added support for DNS requests via TCP. By default, requests are done
via UDP. In case truncated response is received new attempt is done
via TCP connection. Added 2 new macros DNS_QUERY_USEVC and
DNS_QUERY_IGNTC to force all requests to be done via TCP and to disable
switch to TCP in case of truncated responses.
Also added possibility for DNS server to listen and receive requests on
TCP port. Current implementation of TCP support in DNS server seems
rather preliminary and maybe changes after discussion and code review.
Fallback to TCP in case of truncated DNS requests is done automatically.
To imitate the old behaviour macros DNS_QUERY_IGNTC should be used. To
force all DNS requests to be done via TCP one should use the flag
DNS_QUERY_USEVC. Names DNS_QUERY_IGNTC, DNS_QUERY_USEVC were chosen to
imitate similar flags in c-ares and glibc."
Ok, interfaces looks good, merging to avoid stalling it for too long.
* evdns-tcp-pr-1004:
evdns: fix coding style issues
evdns: fix trailing whitespaces
evdns: bufferevent_setcb before bufferevent_free is redundant
evdns: Implement dns requests via tcp
libevent is lacking a scalable backend on Windows. Let's leverage the wepoll
library until Windows comes up with an epoll/kqueue compete user mode API.
- All regress tests pass for standard wepoll
- These 2 tests fail intermittently for changelist wepoll, so disabling
changelist wepoll for now
http/cancel_inactive_server
http/stream_in
- verify target on Windows runs tests for both wepoll and win32 backends
- wepoll backend preferred over win32 backend
- wepoll version 1.5.6
v2: cleaner backend abstraction. Disallow wepoll on MinGW/Cygwin.
v3: Add wepoll.h to dist
v4: Make sure wepoll source files are excluded from cygwin/mingw builds
v5: Keep win32 as default backend on windows.
v6: Include wepoll in mingw builds. Verified that regress tests pass w/ WEPOLL backend.
v7: Enable wepoll on mingw when building with cmake
v8: Add wepoll testrunner for autotools test target
v2 (by azat):
- drop package installations
- use local .abi-check over $HOME/abi-check for build dir
- drop regex check, simply use default values (too complex otherwise)
- use sub-shell to avoid cd back
- add missing quotes
- make the style uniq across the whole file (no tabs for indent, copy-paste?)
- drop `set -x`, use `bash -x abi-check.sh` over
- drop EVENT_ABI_CHECK
- use /usr/bin/env bash as shebang
- use `find | xargs` over `cp $(grep -v)`
- adjust markdown syntax in abi-check/README.md
- adjust link to the publicly available documentation
v3 (by azat):
- docker image
- git check-ignore
- make -j8
- allow to change defaults

Should fix the following current failures:
- 2020-05-04T22:32:02.9490248Z C:\Program Files (x86)\Microsoft Visual Studio\2019\Enterprise\MSBuild\Microsoft\VC\v160\Microsoft.CppCommon.targets(231,5): error MSB6006: "cmd.exe" exited with code 3. [D:\a\libevent\libevent\build\regress.vcxproj]
- cmake : /usr/bin/sh: /C/hostedtoolcache/windows/Python/3.7.6/x64/python.exe: No such file or directory
P.S. I guess python has another path, but on my fork it is the same and
it passes.
- EV_CLOSED is EPOLLRDHUP in epoll
- EPOLLRDHUP reported w/o EPOLLHUP if the socket closed with shutdown(SHUT_WR)
- EPOLLRDHUP reported w/ EPOLLHUP if the socket closed with close()
so in this case epoll backend will detect this event as error
(EV_READ|EV_WRITE), since the epoll_ctl() will return EPOLLRDHUP with
EPOLLHUP set, but this is not correct, let's fix this.
Fixes: #984
* EV_CLOSED-and-EV_ET-fixes:
Avoid triggering wrong events with EV_ET set
epoll: handle EV_ET for EV_CLOSED too
test: cover EV_CLOSED with lots of possible scenarious
test: rename simpleclose to simpleclose_rw (since it works via write/read)
For the event at least something except EV_ET should be set, so checking
ev->ev_events with "triggered" events is wrong, because EV_ET is always
passed (see epoll), since it will be filtered out if it is not set in
event.
