The libevent API provides a mechanism to execute a callback function when
a specific event occurs on a file descriptor or after a timeout has been
reached. Furthermore, libevent also support callbacks due to signals or
regular timeouts.
libevent is meant to replace the event loop found in event driven network
servers. An application just needs to call event_dispatch() and then add
or remove events dynamically without having to change the event loop.
Currently, libevent supports /dev/poll, kqueue(2), event ports, select(2),
poll(2) and epoll(4). The internal event mechanism is completely independent
of the exposed event API, and a simple update of libevent can provide new
functionality without having to redesign the applications. As a result,
Libevent allows for portable application development and provides the most
scalable event notification mechanism available on an operating system.
Libevent can also be used for multi-threaded applications.
===> The following configuration options are available for libevent-2.1.13:
OPENSSL=on: SSL/TLS support via OpenSSL
THREADS=on: Threading support
===> Use 'make config' to modify these settings
devel/libevent: Update to 2.1.13
Changes in version 2.1.13-stable (01 July 2026)
This release contains several security fixes, affecting users of the
following modules: evbuffer, bufferevent, evtag, evrpc, evdns, evhttp.
If you have a program that uses one of those modules,
or if you distribute libevent, you should upgrade.
Additionally, this release backports some small modernizations to
the libevent codebase, to aid in compiling with the compilers
released over the last few years.
Security Fixes (evtag, evrpc):

devel/libevent: register CONFLICTS_INSTALL with -devel port
While here, drop needless OPENSSL_{CPP,LD}FLAGS assignments.
With DEFAULT_VERSIONS+=ssl=openssl|libressl, the following
definitions end up in the ${WRKSRC}/Makefile without manual
specification of the paths, as they come from pkgconf(1):
OPENSSL_INCS = -I/usr/local/include
OPENSSL_LIBS = -L/usr/local/lib -lssl -lcrypto
With default OpenSSL implementation (base):
OPENSSL_INCS =
OPENSSL_LIBS = -lssl -lcrypto
Remove WWW entries moved into port Makefiles
Commit b7f05445c00f has added WWW entries to port Makefiles based on
WWW: lines in pkg-descr files.
This commit removes the WWW: lines of moved-over URLs from these
pkg-descr files.
Approved by: portmgr (tcberner)
Add WWW entries to port Makefiles
It has been common practice to have one or more URLs at the end of the
ports' pkg-descr files, one per line and prefixed with "WWW:". These
URLs should point at a project website or other relevant resources.
Access to these URLs required processing of the pkg-descr files, and
they have often become stale over time. If more than one such URL was
present in a pkg-descr file, only the first one was tarnsfered into
the port INDEX, but for many ports only the last line did contain the
port specific URL to further information.
There have been several proposals to make a project URL available as
a macro in the ports' Makefiles, over time.

devel/libevent: Fix QA warning
Need shebangfix for Python script, but we will consciously avoid adding
Python as a build or run dependency for a script that is unlikely to be
used.

Only use libevent2
Remove libevent as libevent2 is providing a good compatibility interface as well
as providing better performances.
Remove custom patches from libevent2 and install libevent2 the regular way
Mark ports abusing private fields of the libevent1 API as broken
Import a patch from fedora to have honeyd working with libevent2
Remove most of the patches necessary to find the custom installation we used to
have for libevent2
With hat: portmgr
Import changes from upstream git repository.
Includes fixes for the following Bug IDs:
#3028594 - evutil.c fcntl() uses long for F_SETFL
#3048812 - Signal socketpair blocking
#3107877 - evdns can issue duplicate tx ids
- Set --mandir and --infodir in CONFIGURE_ARGS if the configure script
supports them. This is determined by running ``configure --help'' in
do-configure target and set the shell variable _LATE_CONFIGURE_ARGS
which is then passed to CONFIGURE_ARGS.
- Remove --mandir and --infodir in ports' Makefile where applicable
Few ports use REINPLACE_CMD to achieve the same effect, remove them too.
- Correct some manual pages location from PREFIX/man to MANPREFIX/man
- Define INFO_PATH where necessary
- Document that .info files are installed in a subdirectory relative to
PREFIX/INFO_PATH and slightly change add-plist-info to use INFO_PATH and
subdirectory detection.

Mass-conversion to the USE_AUTOTOOLS New World Order. The code present
in bsd.autotools.mk essentially makes this a no-op given that all the
old variables set a USE_AUTOTOOLS_COMPAT variable, which is parsed in
exactly the same way as USE_AUTOTOOLS itself.
Moreover, USE_AUTOTOOLS has already been extensively tested by the GNOME
team -- all GNOME 2.12.x ports use it.
Preliminary documentation can be found at:
http://people.FreeBSD.org/~ade/autotools.txt
which is in the process of being SGMLized before introduction into the
Porters Handbook.
