# Contributing to the libevent
## Coding style
First and most generic rule: **just look around**.
But, we have a script for checking patches/files/git-refs:
```shell
# Chech HEAD git ref
./checkpatch.sh -r
./checkpatch.sh -r HEAD
# Check patch
git format-patch --stdout -1 | ./checkpatch.sh -p
git show -1 | ./checkpatch.sh -p
# Or via regular files
git format-patch --stdout -2
./checkpatch.sh *.patch
# Over a file
./checkpatch.sh -d event.c
./checkpatch.sh -d < event.c
# And print the whole file not only summary
./checkpatch.sh -f event.c
./checkpatch.sh -f < event.c
# See
./checkpatch.sh -h
```
## Testing
- Write new unit test in `test/regress_{MORE_SUITABLE_FOR_YOU}.c`
- `make verify`

o Fix memory-leak of signal handler array with kqueue. [backport] (01f3775)
o Update sample/signal-test.c to use newer APIs and not leak. (891765c Evan Jones)
o Correct all versions in 1.4 branch (ac0d213)
o Make evutil_make_socket_nonblocking() leave any other flags alone. (81c26ba Jardel Weyrich)

o Make Libevent 1.4 build on win32 with Unicode enabled. (bce58d6 Brodie Thiesfield)
o Distribute nmake makefile for 1.4 (20d706d)
o do not fail while sending on http connections the client closed. (5c8b446)
o make evhttp_send() safe against terminated connections, too (01ea0c5)
o Fix a free(NULL) in min_heap.h (2458934)
o Fix memory leak when setting up priorities; reported by Alexander Drozdov (cb1a722)
o Clean up properly when adding a signal handler fails. (ae6ece0 Gilad Benjamini)

o Fix compile warning in http.c (906d573)
o Define _REENTRANT as needed on Solaris, elsewhere (6cbea13)
Changes in 1.4.13-stable:
o If the kernel tells us that there are a negative number of bytes to read from a socket, do not believe it. Fixes bug 2841177; found by Alexander Pronchenkov.
o Do not allocate the maximum event queue and fd array for the epoll backend at startup. Instead, start out accepting 32 events at a time, and double the queue's size when it seems that the OS is generating events faster than we're requesting them. Saves up to 512K per epoll-based event_base. Resolves bug 2839240.
o Fix compilation on Android, which forgot to define fd_mask in its sys/select.h
o Do not drop data from evbuffer when out of memory; reported by Jacek Masiulaniec
o Rename our replacement compat/sys/_time.h header to avoid build a conflict on HPUX; reported by Kathryn Hogg.
o Build kqueue.c correctly on GNU/kFreeBSD platforms. Patch pulled upstream from Debian.
o Fix a problem with excessive memory allocation when using multiple event priorities.
o When running set[ug]id, don't check the environment. Based on a patch from OpenBSD.
Changes in 1.4.12-stable:
o Try to contain degree of failure when running on a win32 version so heavily firewalled that we can't fake a socketpair.
o Fix an obscure timing-dependent, allocator-dependent crash in the evdns code.
o Use __VA_ARGS__ syntax for varargs macros in event_rpcgen when compiler is not GCC.
o Activate fd events in a pseudorandom order with O(N) backends, so that we don't systematically favor low fds (select) or earlier-added fds (poll, win32).
o Fix another pair of fencepost bugs in epoll.c. [Patch from Adam Langley.]
o Do not break evdns connections to nameservers when our IP changes.
o Set truncated flag correctly in evdns server replies.
o Disable strict aliasing with GCC: our code is not compliant with it.
Changes in 1.4.11-stable:
o Fix a bug when removing a timeout from the heap. [Patch from Marko Kreen]
o Remove the limit on size of HTTP headers by removing static buffers.
o Fix a nasty dangling pointer bug in epoll.c that could occur after epoll_recalc(). [Patch from Kevin Springborn]
o Distribute Win32-Code/event-config.h, not ./event-config.h
Changes in 1.4.10-stable:
o clean up buffered http connection data on reset; reported by Brian O'Kelley
o bug fix and potential race condition in signal handling; from Alexander Drozdov
o rename the Solaris event ports backend to evport
o support compilation on Haiku
o fix signal processing when a signal callback delivers a signal; from Alexander Drozdov

o Fix a typo in setting the global event base; reported by lance.
o Fix a memory leak when reading multi-line headers
o Fix a memory leak by not running explicit close detection for server connections
Changes in 1.4.8-stable:
o Match the query in DNS replies to the query in the request; from Vsevolod Stakhov.
o Fix a merge problem in which name_from_addr returned pointers to the stack; found by Jiang Hong.
o Do not remove Accept-Encoding header
Changes in 1.4.7-stable:
o Fix a bug where headers arriving in multiple packets were not parsed; fix from Jiang Hong; test by me.
Changes in 1.4.6-stable:
o evutil.h now includes <stdarg.h> directly
o switch all uses of [v]snprintf over to evutil
o Correct handling of trailing headers in chunked replies; from Scott Lamb.
o Support multi-line HTTP headers; based on a patch from Moshe Litvin
o Reject negative Content-Length headers; anonymous bug report
o Detect CLOCK_MONOTONIC at runtime for evdns; anonymous bug report
o Fix a bug where deleting signals with the kqueue backend would cause subsequent adds to fail
o Support multiple events listening on the same signal; make signals regular events that go on the same event queue; problem report by Alexander Drozdov.
o Deal with evbuffer_read() returning -1 on EINTR|EAGAIN; from Adam Langley.
o Fix a bug in which the DNS server would incorrectly set the type of a cname reply to a.
o Fix a bug where setting the timeout on a bufferevent would take not effect if the event was already pending.
o Fix a memory leak when using signals for some event bases; reported by Alexander Drozdov.

Changes in 1.4.5-stable:
o Fix connection keep-alive behavior for HTTP/1.0
o Fix use of freed memory in event_reinit; pointed out by Peter Postma
o Constify struct timeval * where possible; pointed out by Forest Wilkinson
o allow min_heap_erase to be called on removed members; from liusifan.
o Rename INPUT and OUTPUT to EVRPC_INPUT and EVRPC_OUTPUT. Retain INPUT/OUTPUT aliases on on-win32 platforms for backwards compatibility.
o Do not use SO_REUSEADDR when connecting
o Fix Windows build
o Fix a bug in event_rpcgen when generated fixed-sized entries
Changes in 1.4.4-stable:
o Correct the documentation on buffer printf functions.
o Don't warn on unimplemented epoll_create(): this isn't a problem, just a reason to fall back to poll or select.
o Correctly handle timeouts larger than 35 minutes on Linux with epoll.c. This is probably a kernel defect, but we'll have to support old kernels anyway even if it gets fixed.
o Fix a potential stack corruption bug in tagging on 64-bit CPUs.
o expose bufferevent_setwatermark via header files and fix high watermark on read
o fix a bug in bufferevent read water marks and add a test for them
o introduce bufferevent_setcb and bufferevent_setfd to allow better manipulation of bufferevents
o use libevent's internal timercmp on all platforms, to avoid bugs on old platforms where timercmp(a,b,<=) is buggy.
o reduce system calls for getting current time by caching it.
o fix evhttp_bind_socket() so that multiple sockets can be bound by the same http server.
o Build test directory correctly with CPPFLAGS set.
o Fix build under Visual C++ 2005.
o Expose evhttp_accept_socket() API.
o Merge windows gettimeofday() replacement into a new evutil_gettimeofday() function.
o Fix autoconf script behavior on IRIX.
o Make sure winsock2.h include always comes before windows.h include.
Changes in 1.4.3-stable:
o include Content-Length in reply for HTTP/1.0 requests with keep-alive
o Patch from Tani Hosokawa: make some functions in http.c threadsafe.
o Do not free the kqop file descriptor in other processes, also allow it to be 0; from Andrei Nigmatulin
o make event_rpcgen.py generate code include event-config.h; reported by Sam Banks.
o make event methods static so that they are not exported; from Andrei Nigmatulin
o make RPC replies use application/octet-stream as mime type
o do not delete uninitialized timeout event in evdns
Changes in 1.4.2-rc:
o remove pending timeouts on event_base_free()
o also check EAGAIN for Solaris' event ports; from W.C.A. Wijngaards
o devpoll and evport need reinit; tested by W.C.A Wijngaards
o event_base_get_method; from Springande Ulv
o Send CRLF after each chunk in HTTP output, for compliance with RFC2626. Patch from "propanbutan". Fixes bug 1894184.
o Add a int64_t parsing function, with unit tests, so we can apply Scott Lamb's fix to allow large HTTP values.
o Use a 64-bit field to hold HTTP content-lengths. Patch from Scott Lamb.
o Allow regression code to build even without Python installed
o remove NDEBUG ifdefs from evdns.c
o update documentation of event_loop and event_base_loop; from Tani Hosokawa.
o detect integer types properly on platforms without stdint.h
o Remove "AM_MAINTAINER_MODE" declaration in configure.in: now makefiles and configure should get re-generated automatically when Makefile.am or configure.in chanes.
o do not insert event into list when evsel->add fails
Changes in 1.4.1-beta:
o free minheap on event_base_free(); from Christopher Layne
o debug cleanups in signal.c; from Christopher Layne
o provide event_base_new() that does not set the current_base global
o bufferevent_write now uses a const source argument; report from Charles Kerr
o better documentation for event_base_loopexit; from Scott Lamb.
o Make kqueue have the same behavior as other backends when a signal is caught between event_add() and event_loop(). Previously, it would catch and ignore such signals.
o Make kqueue restore signal handlers correctly when event_del() is called.
o provide event_reinit() to reintialize an event_base after fork
o small improvements to evhttp documentation
o always generate Date and Content-Length headers for HTTP/1.1 replies
o set the correct event base for HTTP close events
o New function, event_{base_}loopbreak. Like event_loopexit, it makes an event loop stop executing and return. Unlike event_loopexit, it keeps subsequent pending events from getting executed. Patch from Scott Lamb
o Removed obsoleted recalc code
o pull setters/getters out of RPC structures into a base class to which we just need to store a pointer; this reduces the memory footprint of these structures.
o fix a bug with event_rpcgen for integers
o move EV_PERSIST handling out of the event backends
o support for 32-bit tag numbers in rpc structures; this is wire compatible, but changes the API slightly.
o prefix {encode,decode}_tag functions with evtag to avoid collisions
o Correctly handle DNS replies with no answers set (Fixes bug 1846282)
o The configure script now takes an --enable-gcc-warnigns option that turns on many optional gcc warnings. (Nick has been building with these for a while, but they might be useful to other developers.)
o When building with GCC, use the "format" attribute to verify type correctness of calls to printf-like functions.
o removed linger from http server socket; reported by Ilya Martynov
o allow \r or \n individually to separate HTTP headers instead of the standard "\r\n"; from Charles Kerr.
o demote most http warnings to debug messages
o Fix Solaris compilation; from Magne Mahre
o Add a "Date" header to HTTP responses, as required by HTTP 1.1.
o Support specifying the local address of an evhttp_connection using set_local_address
o Fix a memory leak in which failed HTTP connections would not free the request object
o Make adding of array members in event_rpcgen more efficient, but doubling memory allocation
o Fix a memory leak in the DNS server
o Fix compilation when DNS_USE_OPENSSL_FOR_ID is enabled
o Fix buffer size and string generation in evdns_resolve_reverse_ipv6().
o Respond to nonstandard DNS queries with "NOTIMPL" rather than by ignoring them.
o In DNS responses, the CD flag should be preserved, not the TC flag.
o Fix http.c to compile properly with USE_DEBUG; from Christopher Layne
o Handle NULL timeouts correctly on Solaris; from Trond Norbye
o Recalculate pending events properly when reallocating event array on Solaris; from Trond Norbye
o Add Doxygen documentation to header files; from Mark Heily
o Add a evdns_set_transaction_id_fn() function to override the default
transaction ID generation code.
o Add an evutil module (with header evutil.h) to implement our standard cross-platform hacks, on the theory that somebody else would like to use them too.
o Fix signals implementation on windows.
o Fix http module on windows to close sockets properly.
o Make autogen.sh script run correctly on systems where /bin/sh isn't bash. (Patch from Trond Norbye, rewritten by Hagne Mahre and then Hannah Schroeter.)
o Skip calling gettime() in timeout_process if we are not in fact waiting for any events. (Patch from Trond Norbye)
o Make test subdirectory compile under mingw.
o Fix win32 buffer.c behavior so that it is correct for sockets (which do not like ReadFile and WriteFile).
o Make the test.sh script run unit tests for the evpoll method.
o Make the entire evdns.h header enclosed in "extern C" as appropriate.
o Fix implementation of strsep on platforms that lack it
o Fix implementation of getaddrinfo on platforms that lack it; mainly, this will make Windows http.c work better. Original patch by Lubomir Marinov.
o Fix evport implementation: port_disassociate called on unassociated events resulting in bogus errors; more efficient memory management; from Trond Norbye and Prakash Sangappa
o support for hooks on rpc input and output; can be used to implement rpc independent processing such as compression or authentication.
o use a min heap instead of a red-black tree for timeouts; as a result finding the min is a O(1) operation now; from Maxim Yegorushkin
o associate an event base with an rpc pool
o added two additional libraries: libevent_core and libevent_extra in addition to the regular libevent. libevent_core contains only the event core whereas libevent_extra contains dns, http and rpc support
o Begin using libtool's library versioning support correctly. If we don't mess up, this will more or less guarantee binaries linked against old versions of libevent continue working when we make changes to libevent that do not break backward compatibility.
o Fix evhttp.h compilation when TAILQ_ENTRY is not defined.
o Small code cleanups in epoll_dispatch().
o Increase the maximum number of addresses read from a packet in evdns to 32.
o Remove support for the rtsig method: it hasn't compiled for a while, and nobody seems to miss it very much. Let us know if there's a good reason to put it back in.
o Rename the "class" field in evdns_server_request to dns_question_class, so that it won't break compilation under C++. Use a macro so that old code won't break. Mark the macro as deprecated.
o Fix DNS unit tests so that having a DNS server with broken IPv6 support is no longer cause for aborting the unit tests.
o Make event_base_free() succeed even if there are pending non-internal events on a base. This may still leak memory and fds, but at least it no longer crashes.
o Post-process the config.h file into a new, installed event-config.h file that we can install, and whose macros will be safe to include in header files.
o Remove the long-deprecated acconfig.h file.
o Do not require #include <sys/types.h> before #include <event.h>.
o Add new evutil_timer* functions to wrap (or replace) the regular timeval manipulation functions.
o Fix many build issues when using the Microsoft C compiler.
o Remove a bash-ism in autogen.sh
o When calling event_del on a signal, restore the signal handler's previous value rather than setting it to SIG_DFL. Patch from Christopher Layne.
o Make the logic for active events work better with internal events; patch from Christopher Layne.
o We do not need to specially remove a timeout before calling event_del; patch from Christopher Layne.

__More variables can be found by running `cmake -LAH <sourcedir_path>`__
## CMake (Windows)
Install CMake: <http://www.cmake.org>
$ md build && cd build
$ cmake -G "Visual Studio 10" .. # Or whatever generator you want to use cmake --help for a list.
$ start libevent.sln
## CMake (Unix)
$ mkdir build && cd build
$ cmake .. # Default to Unix Makefiles.
$ make
$ make verify # (optional)
# 1. BUILDING AND INSTALLATION (In Depth)
## Autoconf
To build libevent, type
$ ./configure && make
(If you got libevent from the git repository, you will
first need to run the included "autogen.sh" script in order to
generate the configure script.)
You can run the regression tests by running
$ make verify
Install as root via
$ make install
Before reporting any problems, please run the regression tests.
To enable the low-level tracing build the library as:
$ CFLAGS=-DUSE_DEBUG ./configure [...]
Standard configure flags should work. In particular, see:
--disable-shared Only build static libraries
--prefix Install all files relative to this directory.
The configure script also supports the following flags:
--enable-gcc-warnings Enable extra compiler checking with GCC.
--disable-malloc-replacement
Don't let applications replace our memory
management functions
--disable-openssl Disable support for OpenSSL encryption.
--disable-thread-support Don't support multithreaded environments.
## CMake (Windows)
(Note that autoconf is currently the most mature and supported build
enviroment for libevent; the cmake instructions here are new and
experimental, though they _should_ be solid. We hope that cmake will
still be supported in future versions of Libevent, and will try to
make sure that happens.)
First of all install <http://www.cmake.org>.
To build libevent using Microsoft Visual studio open the "Visual Studio Command prompt" and type:
```
$ cd <libevent source dir>
$ mkdir build && cd build
$ cmake -G "Visual Studio 10" .. # Or whatever generator you want to use cmake --help for a list.
$ start libevent.sln
```
In the above, the ".." refers to the dir containing the Libevent source code.
You can build multiple versions (with different compile time settings) from the same source tree
by creating other build directories.
It is highly recommended to build "out of source" when using
CMake instead of "in source" like the normal behaviour of autoconf for this reason.
The "NMake Makefiles" CMake generator can be used to build entirely via the command line.
To get a list of settings available for the project you can type:
```
$ cmake -LH ..
```
### GUI
CMake also provides a GUI that lets you specify the source directory and output (binary) directory
that the build should be placed in.
### OpenSSL support
To build Libevent with OpenSSL support you will need to have OpenSSL binaries available when building,
these can be found here: <http://www.openssl.org/related/binaries.html>

# DESCRIPTION:
# ============
# Vagrant for running libevent tests with:
# - timeout 30min, to avoid hungs
# - run tests in parallel under ctest (10 concurency)
# - if you have uncommited changes, you should commit them first to check
# - unix only, because of some tar'ing to avoid one vm affect another
#
# ENVIRONMENT:
# ============
# - NO_PKG -- do not install packages
# - NO_CMAKE -- do not run with cmake
# - NO_AUTOTOOLS -- do not run with autoconf/automake

# to allow running boxes provisions in parallel, we can't share the same dirs
# via virtualbox, however sometimes it is the only way, so instead let's
# create an archive of HEAD (this way we will not have any trash there) and
# extract it for every box to the separate folder.

# P.S. we will change this --prefix with tar(1) --trasnform

/*
* This file defines data structures for different types of trees:
* splay trees and red-black trees.
*
* A splay tree is a self-organizing data structure. Every operation
* on the tree causes a splay to happen. The splay moves the requested
* node to the root of the tree and partly rebalances it.
*
* This has the benefit that request locality causes faster lookups as
* the requested nodes move to the top of the tree. On the other hand,
* every lookup causes memory writes.
*
* The Balance Theorem bounds the total access time for m operations
* and n inserts on an initially empty tree as O((m + n)lg n). The
* amortized cost for a sequence of m accesses to a splay tree is O(lg n);
*
* A red-black tree is a binary search tree with the node color as an
* extra attribute. It fulfills a set of conditions:
* - every search path from the root to a leaf consists of the
* same number of black nodes,
* - each red node (except for the root) has a black parent,
* - each leaf node is black.
*
* Every operation on a red-black tree is bounded as O(lg n).
* The maximum height of a red-black tree is 2lg (n+1).

# 2012-01-31, Lars Bilke
# - Enable Code Coverage
#
# 2013-09-17, Joakim Söderberg
# - Added support for Clang.
# - Some additional usage instructions.
#
# 2016-11-02, Azat Khuzhin
# - Adopt for C compiler only (libevent)
#
# USAGE:
# 1. Copy this file into your cmake modules path.
#
# 2. Add the following line to your CMakeLists.txt:
# INCLUDE(CodeCoverage)
#
# 3. Set compiler flags to turn off optimization and enable coverage:
# SET(CMAKE_CXX_FLAGS "-g -O0 -fprofile-arcs -ftest-coverage")
# SET(CMAKE_C_FLAGS "-g -O0 -fprofile-arcs -ftest-coverage")
#
# 3. Use the function SETUP_TARGET_FOR_COVERAGE to create a custom make target
# which runs your test executable and produces a lcov code coverage report:
# Example:
# SETUP_TARGET_FOR_COVERAGE(
# my_coverage_target # Name for custom target.
# test_driver # Name of the test driver executable that runs the tests.
# # NOTE! This should always have a ZERO as exit code
# # otherwise the coverage generation will not complete.
# coverage # Name of output directory.
# )
#
# 4. Build a Debug build:
# cmake -DCMAKE_BUILD_TYPE=Debug ..
# make
# make my_coverage_target
#
#
# Check prereqs

## -MM, not -M (despite what the docs say).
## - Using -M directly means running the compiler twice (even worse

## This next piece of magic avoids the "deleted header file" problem.

## dummy dependencies for each header file. Too bad gcc doesn't do

.Sh DESCRIPTION
Welcome, gentle reader
.Pp
Async DNS lookups are really a whole lot harder than they should be,
mostly stemming from the fact that the libc resolver has never been
very good at them. Before you use this library you should see if libc
can do the job for you with the modern async call getaddrinfo_a
(see http://www.imperialviolet.org/page25.html#e498). Otherwise,
please continue.
.Pp
This code is based on libevent and you must call event_init before
any of the APIs in this file. You must also seed the OpenSSL random
source if you are using OpenSSL for ids (see below).
.Pp
This library is designed to be included and shipped with your source
code. You statically link with it. You should also test for the
existence of strtok_r and define HAVE_STRTOK_R if you have it.
.Pp
The DNS protocol requires a good source of id numbers and these
numbers should be unpredictable for spoofing reasons. There are
three methods for generating them here and you must define exactly
one of them. In increasing order of preference:
.Pp
.Bl -tag -width "DNS_USE_GETTIMEOFDAY_FOR_ID" -compact -offset indent
.It DNS_USE_GETTIMEOFDAY_FOR_ID
Using the bottom 16 bits of the usec result from gettimeofday. This
is a pretty poor solution but should work anywhere.
.It DNS_USE_CPU_CLOCK_FOR_ID
Using the bottom 16 bits of the nsec result from the CPU's time
counter. This is better, but may not work everywhere. Requires
POSIX realtime support and you'll need to link against -lrt on
glibc systems at least.
.It DNS_USE_OPENSSL_FOR_ID
Uses the OpenSSL RAND_bytes call to generate the data. You must
have seeded the pool before making any calls to this library.
.El
.Pp
The library keeps track of the state of nameservers and will avoid
them when they go down. Otherwise it will round robin between them.
.Pp
Quick start guide:
#include "evdns.h"
void callback(int result, char type, int count, int ttl,
void *addresses, void *arg);
evdns_resolv_conf_parse(DNS_OPTIONS_ALL, "/etc/resolv.conf");
evdns_resolve("www.hostname.com", 0, callback, NULL);
.Pp
When the lookup is complete the callback function is called. The
first argument will be one of the DNS_ERR_* defines in evdns.h.
Hopefully it will be DNS_ERR_NONE, in which case type will be
DNS_IPv4_A, count will be the number of IP addresses, ttl is the time
which the data can be cached for (in seconds), addresses will point
to an array of uint32_t's and arg will be whatever you passed to
evdns_resolve.
.Pp
Searching:
.Pp
In order for this library to be a good replacement for glibc's resolver it
supports searching. This involves setting a list of default domains, in
which names will be queried for. The number of dots in the query name
determines the order in which this list is used.
.Pp
Searching appears to be a single lookup from the point of view of the API,
although many DNS queries may be generated from a single call to
evdns_resolve. Searching can also drastically slow down the resolution
of names.
.Pp
To disable searching:
.Bl -enum -compact -offset indent
.It
Never set it up. If you never call
.Fn evdns_resolv_conf_parse,
.Fn evdns_init,
or
.Fn evdns_search_add
then no searching will occur.
.It
If you do call
.Fn evdns_resolv_conf_parse
then don't pass
.Va DNS_OPTION_SEARCH
(or
.Va DNS_OPTIONS_ALL,
which implies it).
.It
When calling
.Fn evdns_resolve,
pass the
.Va DNS_QUERY_NO_SEARCH
flag.
.El
.Pp
The order of searches depends on the number of dots in the name. If the
number is greater than the ndots setting then the names is first tried
globally. Otherwise each search domain is appended in turn.
.Pp
The ndots setting can either be set from a resolv.conf, or by calling
evdns_search_ndots_set.
.Pp
For example, with ndots set to 1 (the default) and a search domain list of
["myhome.net"]:
Query: www
Order: www.myhome.net, www.
.Pp
Query: www.abc
Order: www.abc., www.abc.myhome.net

.Bl -tag -width 0123456
.It Ft int Fn evdns_init
Initializes support for non-blocking name resolution by calling
.Fn evdns_resolv_conf_parse
on UNIX and
.Fn evdns_config_windows_nameservers
on Windows.
.It Ft int Fn evdns_nameserver_add "unsigned long int address"
Add a nameserver. The address should be an IP address in
network byte order. The type of address is chosen so that
it matches in_addr.s_addr.
Returns non-zero on error.
.It Ft int Fn evdns_nameserver_ip_add "const char *ip_as_string"
This wraps the above function by parsing a string as an IP
address and adds it as a nameserver.
Returns non-zero on error
.It Ft int Fn evdns_resolve "const char *name" "int flags" "evdns_callback_type callback" "void *ptr"
Resolve a name. The name parameter should be a DNS name.
The flags parameter should be 0, or DNS_QUERY_NO_SEARCH
which disables searching for this query. (see defn of
searching above).
.Pp
The callback argument is a function which is called when
this query completes and ptr is an argument which is passed
to that callback function.
.Pp
Returns non-zero on error
.It Ft void Fn evdns_search_clear
Clears the list of search domains
.It Ft void Fn evdns_search_add "const char *domain"
Add a domain to the list of search domains
.It Ft void Fn evdns_search_ndots_set "int ndots"
Set the number of dots which, when found in a name, causes
the first query to be without any search domain.
.It Ft int Fn evdns_count_nameservers "void"
Return the number of configured nameservers (not necessarily the
number of running nameservers). This is useful for double-checking
whether our calls to the various nameserver configuration functions
have been successful.
.It Ft int Fn evdns_clear_nameservers_and_suspend "void"
Remove all currently configured nameservers, and suspend all pending
resolves. Resolves will not necessarily be re-attempted until
evdns_resume() is called.
.It Ft int Fn evdns_resume "void"
Re-attempt resolves left in limbo after an earlier call to
evdns_clear_nameservers_and_suspend().
.It Ft int Fn evdns_config_windows_nameservers "void"
Attempt to configure a set of nameservers based on platform settings on
a win32 host. Preferentially tries to use GetNetworkParams; if that fails,
looks in the registry. Returns 0 on success, nonzero on failure.
.It Ft int Fn evdns_resolv_conf_parse "int flags" "const char *filename"
Parse a resolv.conf like file from the given filename.
.Pp
See the man page for resolv.conf for the format of this file.
The flags argument determines what information is parsed from
this file:
.Bl -tag -width "DNS_OPTION_NAMESERVERS" -offset indent -compact -nested
.It DNS_OPTION_SEARCH
domain, search and ndots options
.It DNS_OPTION_NAMESERVERS
nameserver lines
.It DNS_OPTION_MISC
timeout and attempts options
.It DNS_OPTIONS_ALL
all of the above
.El
.Pp
The following directives are not parsed from the file:
sortlist, rotate, no-check-names, inet6, debug
.Pp
Returns non-zero on error:
.Bl -tag -width "0" -offset indent -compact -nested
.It 0
no errors
.It 1
failed to open file
.It 2
failed to stat file
.It 3
file too large
.It 4
out of memory
.It 5
short read from file
.El
.El
.Sh Internals:
Requests are kept in two queues. The first is the inflight queue. In
this queue requests have an allocated transaction id and nameserver.
They will soon be transmitted if they haven't already been.
.Pp
The second is the waiting queue. The size of the inflight ring is
limited and all other requests wait in waiting queue for space. This
bounds the number of concurrent requests so that we don't flood the
nameserver. Several algorithms require a full walk of the inflight
queue and so bounding its size keeps thing going nicely under huge
(many thousands of requests) loads.
.Pp
If a nameserver loses too many requests it is considered down and we
try not to use it. After a while we send a probe to that nameserver
(a lookup for google.com) and, if it replies, we consider it working
again. If the nameserver fails a probe we wait longer to try again
with the next probe.

.Sh HISTORY
The
.Nm evdns
API was developed by Adam Langley on top of the
.Nm libevent
API.
The code was integrate into
.Nm Tor
by Nick Mathewson and finally put into
.Nm libevent
itself by Niels Provos.
.Sh AUTHORS
The
.Nm evdns
API and code was written by Adam Langley with significant
contributions by Nick Mathewson.
.Sh BUGS
This documentation is neither complete nor authoritative.
If you are in doubt about the usage of this API then
check the source code to find out how it works, write
up the missing piece of documentation and send it to
me for inclusion in this man page.

.Sh DESCRIPTION
The
.Nm event
API provides a mechanism to execute a function when a specific event
on a file descriptor occurs or after a given time has passed.
.Pp
The
.Nm event
API needs to be initialized with
.Fn event_init
before it can be used.
.Pp
In order to process events, an application needs to call
.Fn event_dispatch .
This function only returns on error, and should replace the event core
of the application program.
.Pp
The function
.Fn event_set
prepares the event structure
.Fa ev
to be used in future calls to
.Fn event_add
and
.Fn event_del .
The event will be prepared to call the function specified by the
.Fa fn
argument with an
.Fa int
argument indicating the file descriptor, a
.Fa short
argument indicating the type of event, and a
.Fa void *
argument given in the
.Fa arg
argument.
The
.Fa fd
indicates the file descriptor that should be monitored for events.
The events can be either
.Va EV_READ ,
.Va EV_WRITE ,
or both,
indicating that an application can read or write from the file descriptor
respectively without blocking.
.Pp
The function
.Fa fn
will be called with the file descriptor that triggered the event and
the type of event which will be either
.Va EV_TIMEOUT ,
.Va EV_SIGNAL ,
.Va EV_READ ,
or
.Va EV_WRITE .
Additionally, an event which has registered interest in more than one of the
preceeding events, via bitwise-OR to
.Fn event_set ,
can provide its callback function with a bitwise-OR of more than one triggered
event.
The additional flag
.Va EV_PERSIST
makes an
.Fn event_add
persistent until
.Fn event_del
has been called.
.Pp
Once initialized, the
.Fa ev
structure can be used repeatedly with
.Fn event_add
and
.Fn event_del
and does not need to be reinitialized unless the function called and/or
the argument to it are to be changed.
However, when an
.Fa ev
structure has been added to libevent using
.Fn event_add
the structure must persist until the event occurs (assuming
.Fa EV_PERSIST
is not set) or is removed
using
.Fn event_del .
You may not reuse the same
.Fa ev
structure for multiple monitored descriptors; each descriptor
needs its own
.Fa ev .
.Pp
The function
.Fn event_add
schedules the execution of the
.Fa ev
event when the event specified in
.Fn event_set
occurs or in at least the time specified in the
.Fa tv .
If
.Fa tv
is
.Dv NULL ,
no timeout occurs and the function will only be called
if a matching event occurs on the file descriptor.
The event in the
.Fa ev
argument must be already initialized by
.Fn event_set
and may not be used in calls to
.Fn event_set
until it has timed out or been removed with
.Fn event_del .
If the event in the
.Fa ev
argument already has a scheduled timeout, the old timeout will be
replaced by the new one.
.Pp
The function
.Fn event_del
will cancel the event in the argument
.Fa ev .
If the event has already executed or has never been added
the call will have no effect.
.Pp
The functions
.Fn evtimer_set ,
.Fn evtimer_add ,
.Fn evtimer_del ,
.Fn evtimer_initialized ,
and
.Fn evtimer_pending
are abbreviations for common situations where only a timeout is required.
The file descriptor passed will be \-1, and the event type will be
.Va EV_TIMEOUT .
.Pp
The functions
.Fn signal_set ,
.Fn signal_add ,
.Fn signal_del ,
.Fn signal_initialized ,
and
.Fn signal_pending
are abbreviations.
The event type will be a persistent
.Va EV_SIGNAL .
That means
.Fn signal_set
adds
.Va EV_PERSIST .
.Pp
In order to avoid races in signal handlers, the
.Nm event
API provides two variables:
.Va event_sigcb
and
.Va event_gotsig .
A signal handler
sets
.Va event_gotsig
to indicate that a signal has been received.
The application sets
.Va event_sigcb
to a callback function.
After the signal handler sets
.Va event_gotsig ,
.Nm event_dispatch
will execute the callback function to process received signals.
The callback returns 1 when no events are registered any more.
It can return \-1 to indicate an error to the
.Nm event
library, causing
.Fn event_dispatch
to terminate with
.Va errno
set to
.Er EINTR .
.Pp
The function
.Fn event_once
is similar to
.Fn event_set .
However, it schedules a callback to be called exactly once and does not
require the caller to prepare an
.Fa event
structure.
This function supports
.Fa EV_TIMEOUT ,
.Fa EV_READ ,
and
.Fa EV_WRITE .
.Pp
The
.Fn event_pending
function can be used to check if the event specified by
.Fa event
is pending to run.
If
.Va EV_TIMEOUT
was specified and
.Fa tv
is not
.Dv NULL ,
the expiration time of the event will be returned in
.Fa tv .
.Pp
The
.Fn event_initialized
macro can be used to check if an event has been initialized.
.Pp
The
.Nm event_loop
function provides an interface for single pass execution of pending
events.
The flags
.Va EVLOOP_ONCE
and
.Va EVLOOP_NONBLOCK
are recognized.
The
.Nm event_loopexit
function exits from the event loop. The next
.Fn event_loop
iteration after the
given timer expires will complete normally (handling all queued events) then
exit without blocking for events again. Subsequent invocations of
.Fn event_loop
will proceed normally.
The
.Nm event_loopbreak
function exits from the event loop immediately.
.Fn event_loop
will abort after the next event is completed;
.Fn event_loopbreak
is typically invoked from this event's callback. This behavior is analogous
to the "break;" statement. Subsequent invocations of
.Fn event_loop
will proceed normally.
.Pp
It is the responsibility of the caller to provide these functions with
pre-allocated event structures.
.Pp
.Sh EVENT PRIORITIES
By default
.Nm libevent
schedules all active events with the same priority.
However, sometimes it is desirable to process some events with a higher
priority than others.
For that reason,
.Nm libevent
supports strict priority queues.
Active events with a lower priority are always processed before events
with a higher priority.
.Pp
The number of different priorities can be set initially with the
.Fn event_priority_init
function.
This function should be called before the first call to
.Fn event_dispatch .
The
.Fn event_priority_set
function can be used to assign a priority to an event.
By default,
.Nm libevent
assigns the middle priority to all events unless their priority
is explicitly set.
.Sh THREAD SAFE EVENTS
.Nm Libevent
has experimental support for thread-safe events.
When initializing the library via
.Fn event_init ,
an event base is returned.
This event base can be used in conjunction with calls to
.Fn event_base_set ,
.Fn event_base_dispatch ,
.Fn event_base_loop ,
.Fn event_base_loopexit ,
.Fn bufferevent_base_set
and
.Fn event_base_free .
.Fn event_base_set
should be called after preparing an event with
.Fn event_set ,
as
.Fn event_set
assigns the provided event to the most recently created event base.
.Fn bufferevent_base_set
should be called after preparing a bufferevent with
.Fn bufferevent_new .
.Fn event_base_free
should be used to free memory associated with the event base
when it is no longer needed.
.Sh BUFFERED EVENTS
.Nm libevent
provides an abstraction on top of the regular event callbacks.
This abstraction is called a
.Va "buffered event" .
A buffered event provides input and output buffers that get filled
and drained automatically.
The user of a buffered event no longer deals directly with the IO,
but instead is reading from input and writing to output buffers.
.Pp
A new bufferevent is created by
.Fn bufferevent_new .
The parameter
.Fa fd
specifies the file descriptor from which data is read and written to.
This file descriptor is not allowed to be a
.Xr pipe 2 .
The next three parameters are callbacks.
The read and write callback have the following form:
.Ft void
.Fn "(*cb)" "struct bufferevent *bufev" "void *arg" .
The error callback has the following form:
.Ft void
.Fn "(*cb)" "struct bufferevent *bufev" "short what" "void *arg" .
The argument is specified by the fourth parameter
.Fa "cbarg" .
A
.Fa bufferevent struct
pointer is returned on success, NULL on error.
Both the read and the write callback may be NULL.
The error callback has to be always provided.
.Pp
Once initialized, the bufferevent structure can be used repeatedly with
bufferevent_enable() and bufferevent_disable().
The flags parameter can be a combination of
.Va EV_READ
and
.Va EV_WRITE .
When read enabled the bufferevent will try to read from the file
descriptor and call the read callback.
The write callback is executed
whenever the output buffer is drained below the write low watermark,
which is
.Va 0
by default.
.Pp
The
.Fn bufferevent_write
function can be used to write data to the file descriptor.
The data is appended to the output buffer and written to the descriptor
automatically as it becomes available for writing.
.Fn bufferevent_write
returns 0 on success or \-1 on failure.
The
.Fn bufferevent_read
function is used to read data from the input buffer,
returning the amount of data read.
.Pp
If multiple bases are in use, bufferevent_base_set() must be called before
enabling the bufferevent for the first time.
.Sh NON-BLOCKING HTTP SUPPORT
.Nm libevent
provides a very thin HTTP layer that can be used both to host an HTTP
server and also to make HTTP requests.
An HTTP server can be created by calling
.Fn evhttp_new .
It can be bound to any port and address with the
.Fn evhttp_bind_socket
function.
When the HTTP server is no longer used, it can be freed via
.Fn evhttp_free .
.Pp
To be notified of HTTP requests, a user needs to register callbacks with the
HTTP server.
This can be done by calling
.Fn evhttp_set_cb .
The second argument is the URI for which a callback is being registered.
The corresponding callback will receive an
.Va struct evhttp_request
object that contains all information about the request.
.Pp
This section does not document all the possible function calls; please
check
.Va event.h
for the public interfaces.
.Sh ADDITIONAL NOTES
It is possible to disable support for
.Va epoll , kqueue , devpoll , poll
or
.Va select
by setting the environment variable
.Va EVENT_NOEPOLL , EVENT_NOKQUEUE , EVENT_NODEVPOLL , EVENT_NOPOLL
or
.Va EVENT_NOSELECT ,
respectively.
By setting the environment variable
.Va EVENT_SHOW_METHOD ,
.Nm libevent
displays the kernel notification method that it uses.
.Sh RETURN VALUES
Upon successful completion
.Fn event_add
and
.Fn event_del
return 0.
Otherwise, \-1 is returned and the global variable errno is
set to indicate the error.
.Sh SEE ALSO
.Xr kqueue 2 ,
.Xr poll 2 ,
.Xr select 2 ,
.Xr evdns 3 ,
.Xr timeout 9
.Sh HISTORY
The
.Nm event
API manpage is based on the
.Xr timeout 9
manpage by Artur Grabowski.
The port of
.Nm libevent
to Windows is due to Michael A. Davis.
Support for real-time signals is due to Taral.
.Sh AUTHORS
The
.Nm event
library was written by Niels Provos.
.Sh BUGS
This documentation is neither complete nor authoritative.
If you are in doubt about the usage of this API then
check the source code to find out how it works, write
up the missing piece of documentation and send it to
me for inclusion in this man page.

/* =====
Turn we now to Windows. Want monontonic time on Windows?
Windows has QueryPerformanceCounter(), which gives time most high-
resolution time. It's a pity it's not so monotonic in practice; it's
also got some fun bugs, especially: with older Windowses, under
virtualizations, with funny hardware, on multiprocessor systems, and so
on. PEP418 [1] has a nice roundup of the issues here.
There's GetTickCount64() on Vista and later, which gives a number of 1-msec
ticks since startup. The accuracy here might be as bad as 10-20 msec, I
hear. There's an undocumented function (NtSetTimerResolution) that
allegedly increases the accuracy. Good luck!
There's also GetTickCount(), which is only 32 bits, but seems to be
supported on pre-Vista versions of Windows. Apparently, you can coax
another 14 bits out of it, giving you 2231 years before rollover.
The less said about timeGetTime() the better.
"We don't care. We don't have to. We're the Phone Company."
-- Lily Tomlin, SNL
Our strategy, if precise timers are turned off, is to just use the best
GetTickCount equivalent available. If we've been asked for precise timing,
then we mostly[2] assume that GetTickCount is monotonic, and correct
GetPerformanceCounter to approximate it.
[1] http://www.python.org/dev/peps/pep-0418
[2] Of course, we feed the Windows stuff into adjust_monotonic_time()
anyway, just in case it isn't.
