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.

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.

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 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 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.

# If we release a new version that changes the binary API, but does
# not break programs compiled against the old binary API, increment
# Current and Age. Set Revision to 0, since this is the first
# implementation of the new API.
#
# Otherwise, we're changing the binary API and breaking bakward
# compatibility with old binaries. Increment Current. Set Age to 0,
# since we're backward compatible with no previous APIs. Set Revision
# to 0 too.
VERSION_INFO = 4:1:2
###
# History:
# We started using Libtool around version 1.0d. For all versions from
# 1.0d through 1.3e, we set RELEASE to the version name, and
# VERSION_INFO to something haphazard. The didn't matter, since
# setting RELEASE meant that no version of Libevent was treated as
# binary-compatible with any other version.
#
# As of 1.4.0-beta, we set RELEASE to "1.4", so that releases in the
# 1.4.x series could be potentially binary-compatible with one another,
# but not with any other series. (They aren't.) We didn't necessarily
# set VERSION_INFO correctly, or update it as often as we should have.
# The VERSION_INFO values were:
# 1.4.0-beta .. 1.4.4-stable : 2:0:0 [See note 1]
# 1.4.5-stable : 3:0:1 (compatible ABI change)
# 1.4.6-stable : 3:1:1 (no ABI change)
# 1.4.7-stable : 3:1:1 [see note 1]
# 1.4.8-stable : 3:2:1 (no ABI change)
# 1.4.9-stable : 3:2:1 [see note 1]
# 1.4.10-stable : 3:3:1 (no ABI change)
# 1.4.11-stable .. 1.4.13-stable : 3:3:1 [see note 1]
# 1.4.14a-stable: : 3:3:2 [see note 2]
# 1.4.14b-stable: : 4:0:2 (compatible ABI change)
# 1.4.15-stable: : 4:1:2 (no ABI change)
#
# [1]: Using the same VERSION_INFO value was wrong; we should have been
# updating the Revision field.
# [2]: We set the VERSION_INFO completely wrong on 1.4.14b-stable

To build libevent, type
$ ./configure && make
(If you got libevent from the subversion repository, you will
first need to run the included "autogen.sh" script in order to
generate the configure script.)
Install as root via
# make install
You can run the regression tests by
$ make verify
Before, reporting any problems, please run the regression tests.
To enable the low-level tracing build the library as:
CFLAGS=-DUSE_DEBUG ./configure [...]

Name: libevent
URL: http://libevent.org/
Version: 1.4.15
License: BSD
Security Critical: yes
Local Modifications:
Rather than use libevent's own build system, we just build a Chrome
static library using GYP.
1) Run configure and "make event-config.h" on Linux, FreeBSD, Solaris,
and Mac and copy config.h and event-config.h to linux/, freebsd/,
solaris/, and mac/ respectively.
2) Add libevent.gyp.
3) chromium.patch is applied to make the following changes:
- Allow libevent to be used without being installed by changing <...>
#includes to "...".
- Fix a race condition in event_del.
- Optimistically assume CLOCK_MONOTONIC is available and fallback if it
fails, rather than explicitly testing for it.
- Remove an unneeded variable that causes a -Werror build failure.
- Add an #ifndef to fix a preprocessor redefined -Werror build failure.
- Revert the patch from http://sourceforge.net/p/levent/bugs/223/ that
introduces use-after-free memory corruption when an event callback frees
the struct event memory.
- Remove deprecated global variables, event_sigcb and event_gotsig
(essentially unused) that trigger tsan errors. (crbug/605894)
4) The directories WIN32-Code and WIN32-Prj are not included.
5) The configs for android were copied from Linux's which were very close to
android one with the exception of HAVE_FD_MASK and HAVE_STRLCPY.
6) Add files to support building with the PNaCl toolchain. Added
libevent_nacl_nonsfi.gyp for build rule. nacl_nonsfi/config.h and
nacl_nonsfi/event-config.h are derived from linux/ counterparts.
nacl_nonsfi/random.c is also added to provide the random() function,
which is missing in the newlib-based PNaCl toolchain.
7) Stub out signal.c for nacl_helper_nonsfi. socketpair() will be prohibited
by sandbox in nacl_helper_nonsfi.
8) Remove an unnecessary workaround for OS X 10.4 from kqueue.c. It was causing
problems on macOS Sierra.
9) Change buffer.c to not redefine _GNU_SOURCE.

/*
* This file defines five types of data structures: singly-linked lists,
* lists, simple queues, tail queues, and circular queues.
*
*
* A singly-linked list is headed by a single forward pointer. The elements
* are singly linked for minimum space and pointer manipulation overhead at
* the expense of O(n) removal for arbitrary elements. New elements can be
* added to the list after an existing element or at the head of the list.
* Elements being removed from the head of the list should use the explicit
* macro for this purpose for optimum efficiency. A singly-linked list may
* only be traversed in the forward direction. Singly-linked lists are ideal
* for applications with large datasets and few or no removals or for
* implementing a LIFO queue.
*
* A list is headed by a single forward pointer (or an array of forward
* pointers for a hash table header). The elements are doubly linked
* so that an arbitrary element can be removed without a need to
* traverse the list. New elements can be added to the list before
* or after an existing element or at the head of the list. A list
* may only be traversed in the forward direction.
*
* A simple queue is headed by a pair of pointers, one the head of the
* list and the other to the tail of the list. The elements are singly
* linked to save space, so elements can only be removed from the
* head of the list. New elements can be added to the list before or after
* an existing element, at the head of the list, or at the end of the
* list. A simple queue may only be traversed in the forward direction.
*
* A tail queue is headed by a pair of pointers, one to the head of the
* list and the other to the tail of the list. The elements are doubly
* linked so that an arbitrary element can be removed without a need to
* traverse the list. New elements can be added to the list before or
* after an existing element, at the head of the list, or at the end of
* the list. A tail queue may be traversed in either direction.
*
* A circle queue is headed by a pair of pointers, one to the head of the
* list and the other to the tail of the list. The elements are doubly
* linked so that an arbitrary element can be removed without a need to
* traverse the list. New elements can be added to the list before or after
* an existing element, at the head of the list, or at the end of the list.
* A circle queue may be traversed in either direction, but has a more
* complex end of list detection.
*
* For details on the use of these macros, see the queue(3) manual page.

.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:

void *addresses, void *arg);

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

.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

.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.

/** @file evdns.h
*
* Welcome, gentle reader
*
* 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.
*
* 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).
*
* 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.
*
* 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:
*
* 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.
* 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.
* 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.
*
* The library keeps track of the state of nameservers and will avoid
* them when they go down. Otherwise it will round robin between them.
*
* 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);
*
* 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.
*
* Searching:
*
* 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.
*
* 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.
*
* To disable searching:
* 1. Never set it up. If you never call evdns_resolv_conf_parse or
* evdns_search_add then no searching will occur.
*
* 2. If you do call evdns_resolv_conf_parse then don't pass
* DNS_OPTION_SEARCH (or DNS_OPTIONS_ALL, which implies it).
*
* 3. When calling evdns_resolve, pass the DNS_QUERY_NO_SEARCH flag.
*
* 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.
*
* The ndots setting can either be set from a resolv.conf, or by calling
* evdns_search_ndots_set.
*
* For example, with ndots set to 1 (the default) and a search domain list of
* ["myhome.net"]:
* Query: www
* Order: www.myhome.net, www.
*
* Query: www.abc
* Order: www.abc., www.abc.myhome.net
*
* 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.
*
* The second is the waiting queue. The size of the inflight ring is

* 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.
*
* 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 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.

* evport.c: event backend using Solaris 10 event ports. See port_create(3C).
* This implementation is loosely modeled after the one used for select(2) (in
* select.c).
*
* The outstanding events are tracked in a data structure called evport_data.
* Each entry in the ed_fds array corresponds to a file descriptor, and contains
* pointers to the read and write events that correspond to that fd. (That is,
* when the file is readable, the "read" event should handle it, etc.)
*
* evport_add and evport_del update this data structure. evport_dispatch uses it
* to determine where to callback when an event occurs (which it gets from
* port_getn).
*
* Helper functions are used: grow() grows the file descriptor array as
* necessary when large fd's come in. reassociate() takes care of maintaining
* the proper file-descriptor/event-port associations.
*
* As in the select(2) implementation, signals are handled by evsignal.

*
* To support RPCs in a server, every supported RPC command needs to be

*
* EVRPC_HEADER(SendCommand, Request, Reply);
*
* SendCommand is the name of the RPC command.
* Request is the name of a structure generated by event_rpcgen.py.
* It contains all parameters relating to the SendCommand RPC. The

* Reply is the name of a structure generated by event_rpcgen.py. It
* contains the answer to the RPC.
*
* To register an RPC with an HTTP server, you need to first create an RPC
* base with:
*
* struct evrpc_base *base = evrpc_init(http);
*
* A specific RPC can then be registered with
*
* EVRPC_REGISTER(base, SendCommand, Request, Reply, FunctionCB, arg);
*
* when the server receives an appropriately formatted RPC, the user callback
* is invokved. The callback needs to fill in the reply structure.
*
* void FunctionCB(EVRPC_STRUCT(SendCommand)* rpc, void *arg);
*
* To send the reply, call EVRPC_REQUEST_DONE(rpc);
*
* See the regression test for an example.

What's New In Libevent 1.4:
0. About this document
This document describes the key differences between Libevent 1.3 and
Libevent 1.4, from a user's point of view. It was most recently
updated based on features from libevent 1.4.2-rc.
1. Packaging Issues.
1.1. The great library division.
The libevent source now builds two libraries: libevent_core and
libevent_extra. The libevent_core library includes event loops,
timers, buffer code, and various small compatibility functions. The
libevent_extra library includes code for HTTP, DNS, RPC, and so on.
Thus, if you're writing software that only uses libevent's event
loop, you should link against only the libevent_core library,
whereas if you're writing software that uses libevent's protocol
support as well, you need to link libevent_extra as well.
For backward compatibility, libevent also builds a library called
"libevent" that includes everything.
1.2. The event-config.h header
Libevent configure script now builds two headers from its configure
script: config.h (which it uses internally) and event-config.h
(which it installs as a header file). All of the macros in
event-config.h are modified so that they're safe to include in other
projects. This allows libevent's header files (like event.h and
evutil.h) information about platform configuration.
What does this mean for you? As of 1.4.x, it should never be
necessary to include extra files or define extra types before you
include event.h (or any other libevent header); event.h can now look
at the information in event-config.h and figure out what it needs to
include.
1.3. Documentation
Libevent now includes better doxygen documentation. It's not
perfect or complete, though; if you find a mistake, please let us
know.
1.4. Libtool usage
We now use libtool's library versioning support correctly. If we
don't mess this up, it means that binaries linked against old
version of libevent should continue working when we make changes to
libevent that don't break backward compatibility.
1.5. Portability
Libevent now builds with MSVC again. We've only tested it with MSVC
2005, and the project files might not be right. Please let us know
if you run into any issues.
Libevent now builds on platforms where /bin/sh is not bash.
Libevent's regression test no longer requires Python to be
installed.
2. New and Improved APIs:
(This list includes functions that are new, functions whose behavior
has changed, and functions that were included in previous releases
but which never actually worked before.)
2.1. Utility functions are defined in evutil.h
Libevent now exposes a small set of functions for cross-platform
network programming in evutil.h, on the theory that they've been
useful enough to us that other people may likely want to use them
too. These are mainly workarounds for Windows issues for now: they
include evutil_socketpair (to fake socketpair on platforms that
don't have it) and evutil_make_socket_nonblocking (to make a socket
nonblocking in a cross-platform way. See the header for more
information.
2.2. In the libevent core.
The event_base_free() function now works. Previously, it would
crash with an assertion failure if there were events pending on a
base. Now, it simply deletes all the pending events and frees the
base. Be careful -- this might leak fds and memory associated with
the old events. To avoid leaks, you should still remove all the
events and free their resources before you delete the base.
Libevent should now work properly with fork(). Just call
event_reinit() on your event base after the fork call, and it should
work okay. Please let us know about any bugs you find.
There's a new event_base_new() function that acts just like
event_init(), but does not replace the default base. If you are
using multiple event bases in your code, you should just use
event_base_new() instead of event_init(), to avoid accidental bugs.
There's new event_loopbreak() function to make a current event loop
stop exiting and return. Unlike event_loopexit, it stops subsequent
pending events from getting executed. This behavior is useful for
scripting languages to implement exceptions from inside callbacks.
There's a new event_base_get_method() function, for use in place of
event_get_method() in multi-base applications.
2.3. New in HTTP.
There's an evhttp_connection_set_local_address() function you can
use to set the local address of an HTTP connection.
HTTP/1.1 chunking now correctly ends chunks with '\r\n'.
2.4. New in DNS
Instead of picking your method for generating DNS transaction IDs at
startup, you can use evdns_set_transaction_id() to provide a
transaction ID function at runtime.
The "class" field in evdns_server_request is now renamed to
dns_question_class, so that it won't break compilation under C++.
This uses some preprocessor hacks so that C code using the old name
won't break. Eventually, the old name will be deprecated entirely;
please don't use it.
2.5. New in RPC
There are now hooks on RPC input and output; can be used to
implement RPC independent processing such as compression or
authentication.
RPC tags can now be up to 32 bits. This is wire-compatible, but
changes some of the types in the APIs. Please let us know if this
is problematic for you.
3. Big bugfixes
We've done a lot, with help from users on different platforms, to
make the different backends behave more similarly with respect to
signals and timeouts. The kqueue and solaris backends were the big
offenders previously, but they should be better now. Windows should
be better too, though it's likely that problems remain there.
The libevent headers (though not the source files!) should now build
cleanly on C++.
(For more bugfixes, see the ChangeLog file. These are only the
biggies.)
4. Big performance improvements
Libevent now uses a min-heap rather than a red-black tree to track
timeouts. This means that finding the next timeout to fire is now
O(1) instead of (lg n).
The win32 select-based backend now uses a red-black tree to map
SOCKET handles to event structures. This changes the performance
characteristics of the event loop on win32 from O(n^2) to O(n lg n).
Not perfect, but better.
5. Removed code and features
The rtsig backend is now removed. It hasn't even compiled for a
while, and nobody seemed to miss it very much. All the platforms
that have rtsig seem to have a better option instead these days.
Please let us know if rtsig was crucial for you.
