Changes in version 2.0.19-stable (3 May 2012)
* Refactor event_persist_closure: raise and extract some common logic
* If time has jumped so we'd reschedule a periodic event in the past, schedule
it for the future instead
* If a higher-priority event becomes active, don't continue running events
of the current priority.
* Fixed potential double-readcb execution with openssl bufferevents.
* Cancel a probe request when the server is freed, and ignore cancelled probe
callbacks
* Remove redundant DNS_ERR_CANCEL check, move comment
* When retransmitting a timed-out DNS request, pick a fresh nameserver.
* Backport: provide EVENT_LOG_* names, and deprecate _EVENT_LOG_*
Changes in version 2.0.18-stable (22 Mar 2012)
* Make uses of open() close-on-exec safe by introducing an internal
evutil_open_closeonexec.
* Properly zero the kevent in kq_setup_kevent()
* Stop crashing in evdns when nameserver probes give a weird error
Changes in version 2.0.17-stable (10 Feb 2012)

* Fix a list corruption bug when using event_reinit() with signals present
* Fix a fd leak in event_reinit()

such as xlc on AIX).

This requires a dependency on Python. Bump PKGREVISION to 1.
This is probably not the best solution: I guess it'd be nice to have a
libevent package that only included the binary libraries and no dependency
on Python, and another libevent-dev package with the event_rpcgen.py binary
and the Python dependency. But this can be done later; I want to just fix
the breakage first.
|
|
Supposedly API backwards-compatible with libevent 1.x.
Will need a recursive revbump for shlib name changes, though.
All regression tests pass except "thread_conditions_simple". Not sure
why yet, but it's new API so shouldn't break anything existing in pkgsrc
today.
Changes in libevent 2.0 include cleaner interfaces, buffered I/O improvements,
improved multithreading and openssl integration.
|
|
|
|
|
|
|
|
This way we sidestep the mess introduced by conflicting libev/libevent,
at least on NetBSD>=5.
|
|
Relax ABI dependency and remove an outdated comment.

Changes in 1.4.12-stable:
Try to contain degree of failure when running on a win32 version so heavily firewalled that we can't fake a socketpair.
Fix an obscure timing-dependent, allocator-dependent crash in the evdns code.
Use __VA_ARGS__ syntax for varargs macros in event_rpcgen when compiler is not GCC.
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).
Fix another pair of fencepost bugs in epoll.c. [Patch from Adam Langley.]
Do not break evdns connections to nameservers when our IP changes.
Set truncated flag correctly in evdns server replies.
Disable strict aliasing with GCC: our code is not compliant with it.
Changes in 1.4.11-stable:
Fix a bug when removing a timeout from the heap. [Patch from Marko Kreen]
Remove the limit on size of HTTP headers by removing static buffers.
Fix a nasty dangling pointer bug in epoll.c that could occur after epoll_recalc(). [Patch from Kevin Springborn]
Distribute Win32-Code/event-config.h, not ./event-config.h
Changes in 1.4.10-stable:
clean up buffered http connection data on reset; reported by Brian O'Kelley
bug fix and potential race condition in signal handling; from Alexander Drozdov
rename the Solaris event ports backend to evport
support compilation on Haiku
fix signal processing when a signal callback delivers a signal; from Alexander Drozdov
const-ify some arguments to evdns functions.
off-by-one error in epoll_recalc; reported by Victor Goya
include Doxyfile in tar ball; from Jeff Garzik
correctly parse queries with encoded \r, \n or + characters

This changes the buildlink3.mk files to use an include guard for the
recursive include. The use of BUILDLINK_DEPTH, BUILDLINK_DEPENDS,
BUILDLINK_PACKAGES and BUILDLINK_ORDER is handled by a single new
variable BUILDLINK_TREE. Each buildlink3.mk file adds a pair of
enter/exit marker, which can be used to reconstruct the tree and
to determine first level includes. Avoiding := for large variables
(BUILDLINK_ORDER) speeds up parse time as += has linear complexity.
The include guard reduces system time by avoiding reading files over and
over again. For complex packages this reduces both %user and %sys time to
half of the former time.

Changes in 1.4.9-stable:
o event_add would not return error for some backends; from Dean
McNamee
o Clear the timer cache on entering the event loop; reported by
Victor Chang
o Only bind the socket on connect when a local address has been
provided; reported by Alejo Sanchez

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.
o Add libevent.vcproj file to distribution to help with Windows build.
o Fix a problem with epoll() and reinit; problem report 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 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.

we can't use config.h in it. Instead use the substitution framework
which was already in place for making some other SunOS changes.
|
|
so use the results.
|
|
libevent-1.3d:
Bug fixes in the HTTP layer.
libevent-1.3c:
Small bug and portability fixes.
Worth mentioning is that patch-ab and patch-ac were applied upstream.
As usual with libevent, this breaks the ABI due to .so naming, so a
small revbump sweep will be needed.
|
|
the select implementation needs sys/select.h. The latter should be
detected by autoconf, but can break e.g. older DragonFly.
|
|
Need for net/spreadload (PR 36348).
|
|
|
|
1.3b:
* Fixes when using signals in multi-threaded applications from Scott Lamb.
* Other small bug fixes.
1.3a:
* Small bug and performances fixes to evhttp layer.
