Coro
view release on metacpan or search on metacpan
failures on perls compiled with -Duselongdouble. Requiring
the latest version of Event because I don't know which release
changed this (it's not mentioned in the ChangeLog).
- allow xs level enterleave hooks via CoroAPI.
6.43 Thu Jun 4 15:38:14 CEST 2015
- use stability canary.
- port to stableperl-5.22.0-1.001.
- update libecb.
6.42 Wed Feb 11 20:29:52 CET 2015
- Coro::SemaphoreSet->try did not actually work (analyzed by
SATO Kentaro).
- upgrade libecb to be C11 compliant.
6.41 Sat Sep 6 22:08:46 CEST 2014
- restore portability to perl 5.8.x.
- give new Coro's a valid GvHV(PL_hintgv) - this is slow and takes
up some memory, but fixes "use feature" and similar modules
when used inside a Coro.
- allow zero as argument to Coro::Channel to mean the same thing
6.39 Mon Jun 2 00:00:08 CEST 2014
- work around more incompatible changes in 5.20.
6.38 Sun Jun 1 21:54:23 CEST 2014
- check that perl slots actually have enough space to hold
interpreter variables.
- untested port to perl 5.19 (64 bit tmps indices) (reported
by Andreas König).
- croak when cancel is called without a thread context.
6.37 Tue Mar 4 13:27:33 CET 2014
- *sigh*, removed leftover debugging code from debugging a
perl bug, of all things.
6.36 Tue Mar 4 07:11:59 CET 2014
- semaphores would not clear the destroy hook when interrupted
by ->throw, causing segfaults or worse.
- ->throw on a thread waiting for a semaphore did not acquire
the semaphore, but also didn't wake up other waiters,
possibly causing a deadlock.
- "FATAL: $Coro::IDLE blocked itself" will now use Carp::confess
to report a full stacktrace, which should help find out
where the actual call is.
- "atomically" destroy data in slf_destroy, because it is
the right thing to do, just in case.
- disable ecb.h libm dependency, to compile on ancient systems
or under adverse conditions.
6.33 Mon Nov 18 11:26:27 CET 2013
- do not crash when freeing padlists with holes (in 5.18).
- tentative SVt_BIND 5.19 port/fix.
6.32 Tue Nov 5 15:35:35 CET 2013
- use a new algorithm to derive padlists for perl 5.18. The old
one could lead to 0-pointer accesses inside perl (reported
by Darin McBride).
6.31 Thu May 9 07:39:48 CEST 2013
- Coro::AIO requests would crash if the thread was ready'd
while the request was ongoing.
6.29 Wed May 8 02:55:18 CEST 2013
- when an on_destroy handler destructs the coro currently being
destructed a perl scalar could be accessed after being freed,
likely causing a crash.
6.28 Wed Mar 6 06:58:02 CET 2013
- clean remnants of existing __DIE__ and __WARN__ handlers so
they lose their magic and will not cause segfaults later
(testcase by Andrey Sagulin).
- improved Coro::State documentation a bit.
- Coro::Debug::command now flushes the output.
- add hack detection code for x32 abi, because the braindead slugs
who designed that made it look exactly like x86_64 without
providing proper compile time symbols to test for it. as a result,
this detection cannot work reliably.
- valgrind stack registering was broken.
- do not rely on Time::HiRes anymore in Coro::Debug.
6.23 Fri Dec 7 23:36:37 CET 2012
- use experimental fiber implementation on native windows
perls.
- use sizeof (void *) as multiplication factor for stack sizes,
to accomodate the totally braindamaged microsoft 64 bit "os".
- changed verifier host from win2k-ap510-32 to win7-sp516-32/64.
activeperl 5.16 crashes when PerlIO_define_layer is called due
to some bug in the perl dll, strawberry perl at least passes
the testsuite.
- implement Coro::Handle->peeraddr/host/port, for slightly
improved compatibility with LWP.
be expected by existing code, and code that doesn't cope with spurious
wakeups needs fixing anyway.
- use fd -1 in mmap.
- cast I32 to int in error message printf.
- warn about broken so-called "hardened" kernels.
6.08 Fri Apr 13 12:05:47 CEST 2012
- be more aggressive about exiting like perl does - formerly,
exiting from the non-main thread would not execute END blocks.
6.07 Fri Nov 11 21:21:48 CET 2011
- work around a bug in PerlIO (setting $SIG{__WARN__} to a PVCV).
- update ecb.h.
6.06 Mon Aug 8 23:59:48 CEST 2011
- cygwin unfortunately patches the stack at runtime, so we use the pthreads
backend, which is an order of magnitude slower. unfortunately, cygwins
pthread implementation isn't very complete either, so allocate the stack
twice just to be sure.
(note: cygwin also enables mymalloc, which is NOT THREADSAFE ON WINDOWS,
in its ithreaded perl - best recompile cygwin and use the 'w'indows
- get rid if coro refcounting - simply crash in other interpreter
threads by nulling the pointers on clone.
- simplify warn/die hook handling when loading Coro - the convoluted
logic seems to be no longer neccessary.
- use libecb instead of our own home-grown gcc hacks.
- document alternatives to Coro::LWP. Please use them :)
- work around another mindless idiotic NEEDLESS bug in openbsd/mirbsds
sigaltstack. Really. wine suffers from it, erlang suffers from it,
and it's known since at least 2006.
5.372 Wed Feb 23 06:14:30 CET 2011
- apparently mingw doesn't provide a working gettimeofday, try to
work around that by relying on Time::HiRes (indirectly brought to
my attention by Max Maischein).
- fix some portability issues when Time::HiRes was used.
5.371 Mon Feb 21 14:36:08 CET 2011
- backport to windows process emulation code again.
5.37 Sat Feb 19 07:49:44 CET 2011
- add a big "Coro thread life cycle" section to "man Coro".
- try a tentative workaround against the breakage that 5.13 has
introduced without depreciation period. sigh.
- no longer use Time::HiRes if gettimeofday is available, which
saves quite a lot of memory.
5.36 Sun Feb 13 05:33:41 CET 2011
- automatically load Coro::Channel, Coro::RWLock, Coro::Semaphore,
Coro::SemaphoreSet, Coro::Signal and Coro::Specific on first "new"
method call.
- undocument Coro::Timer::sleep and obsolete whole module.
- optimise Coro::Timer::timeout memory and cpu usage.
- slightly updated Coro::Intro for recent changes.
- do not initialise PL_dirty anymore.
5.25 Thu Nov 11 01:08:39 CET 2010
- try a different approach on netbsd - netbsd 5 finally has marginally
working pthreads, but still broken ucontext/sigaltstack.
- openbsd 4.8 finally got their act together, Coro works out of the box
with asm, setjmp and pthreads (no change, just informational).
5.24 Sat Oct 23 11:27:12 CEST 2010
- port to the EV 4.0 API.
- work around bugs in mingw32, making strawberry perl work
out of the box.
- correctly modify Coro::AIO function prototypes
are less useful now, but are drop-in replacements for existing
functions, listing better alternatives in the documentation. This also
fixes a bug in Coro::LWP which naively substituted Socket::inet_aton
with Coro::Util::inet_aton.
- do not override $Coro::idle unconditionally in Coro.pm, as other
modules could have provided their own idle coro already
(for exmaple, Coro::AnyEvent).
- fix Coro::Util::gethost* functions.
- Coro::Timer corretcly exports it's symbols (reported by Hideki Yamamura).
5.21 Wed Dec 16 07:19:51 CET 2009
- automatically load Coro::AnyEvent when AnyEvent and Coro are used
together.
- add some examples on how to combine other event loops with Coro in
Coro::AnyEvent, and how to run it (and not to block). Seems to be
the most common source of confusion.
- try to catch people naively blocking in an event callback.
- work around the perl filehandle bug issue in conjunction with
older common::sense (as indirectly pointed out by ZSystem).
- clarify the "not from signal handlers" section.
- avoid unneccessary ->cancel calls in Coro::Handle.
- maybe make it work on mingw32 with win32 backend
(based on patch by Yasuhiro Matsumoto).
5.132 Fri May 29 09:00:39 CEST 2009
- do not keep a reference to the argument itself in
Coro::Semaphore::guard, as it could change later.
- support SO_RCVBUF/SO_SNDBUF nonstandard Coro::Socket options,
should support a prepare callback.
5.131 Mon Mar 16 23:20:37 CET 2009
- implement and document Coro->suspend, Coro->resume.
- fix Coro::Select implementation to not (often) close
the passed file descriptors (testcase provided by pippijn).
5.13 Mon Dec 15 21:51:42 CET 2008
- EXPERIMENTAL: implement dynamic winds (on_enter/on_leave).
- don't set diehook to C<undef> but instead to NULL, to avoid
spurious warnings.
- fix a lot of bugs in Coro::SemaphoreSet.
- Coro::SemaphoreSet will less often create a semaphore needlessly.
- add Coro::SemaphoreSet::count and wait methods.
- take advantage of the new Guard module.
- deprecate Coro::guard.
- try to fix the dreaded 01_unblock tests once more. I hate it when
testsuites need more fixing than the code they are supposed to test.
- croak in more cases when a required callback isn't resolvable.
- fix some minor issues in Coro::State->call/eval.
- use current coroutine context instead of a temporary one
when temporarily switching to another coroutine.
- do not call C-level on_destroy handlers during global destruction,
to avoid needless segfaults.
5.12 Sun Dec 7 13:30:38 CET 2008
- add default config for MirOS, which seems to be a bug-to-bug
compatible fork of openbsd ("world domination by releasing
openbsd cvs before the openbsd folks do it" or so :).
- free_padlist did destroy the names pad, not good, but didn't
seem to bother perl - this could fix issues such as eval ""
inside a function called from multiple coroutines.
- use a different method to detect destruction time.
- be more careful when freeing padlists just before global
destruction.
- fixed and expanded the call/cc example.
- renamed _terminate to _coro_run.
- new method Coro::Channel->shutdown.
- try pthreads on openbsd <4.4 (broken sigaltstack, will
pthreads fare better?).
- be less picky about destroying "a" running coroutine.
5.11 Tue Nov 25 21:49:05 CET 2008
- DEBUGGING in 5.10.0 is a mess: it constantly flags perfectly
working code with failed assertions, introducing more bugs than
it fixes, requiring elaborate workarounds :(
5.1 Mon Nov 24 08:54:59 CET 2008
- wrote a small introductory tutorial - Coro::Intro.
- convert Coro::Timer, Coro::Select and Coro::Util to rouse API.
- Coro::Select did errornously dup the file descriptors
and didn't work with all AnyEvent backends.
- Coro::Select wasn't imported correctly form Coro::LWP, causing blocking
LWP data transfers.
- disassociate c contexts from coro objects - this is agruably more
correct, but mostly allows sharing of cctxs between coro and state
objects, for added memory savings and speed increases.
- bumped $Coro::POOL_RSS up to 32kb by default.
do not have this method (and don't need it either).
- speed up generic anyevent methods in Coro::Handle by using rouse
callbacks.
- allow coroutines in $Coro::IDLE, speeding up Coro::AnyEvent and
others. It also makes the debugger happier, as you can trace
through the idle threads now.
- add comppad_name* and hints ($^H, %^H) to per-thread variables.
- eg/event was pretty broken.
- better 5.8.6 compatibility.
5.0 Thu Nov 20 10:35:05 CET 2008
- NEW ARCHITECTURE: use the latest 4.x version if you experience
stability issues.
- bump API version to 7 - all dependents must be recompiled.
- removed timed_* functions - they were not being used anyways
and should be replaced by a more generic mechanism -
and were annoying to support anyways :)
- removed SemaphoreSet's waiter method - use sem method instead.
- Coro::Semaphore->adjust didn't correctly wake up enough waiters.
- async_pool did free a scalar value twice
("Attempt to unreference...").
a normal async is now very small.
- sped up coroutine creation/destruction by 40%.
- forgot to include Coro/libcoro/README in the dist for all these years.
- work around a freebsd pthreads bug (manual testcancel is required as
pthread_cond_wait isn't a cancellation point on freebsd).
- use new rouse functions to speed up and simplify Coro::BDB.
- make "prefer perl native functions" work with threaded perls.
- condense Coro::Debug ps output, hint at v and w flags.
- (libcoro) lots of minor cleanups and portability improvements.
4.914 Wed Nov 19 12:54:18 CET 2008
- fix a disastrous bug in the readline optimisation
introduced in 4.801.
4.913 Sat Nov 15 07:58:28 CET 2008
- async_pool did free a scalar value twice
("Attempt to unreference...").
4.912 Thu Nov 13 18:31:23 CET 2008
- minor cleanups.
- use much larger stacks on linux and perl < 5.8.8.
- Coro::Debug::new_unix_server did not unlink the socket
when destroyed.
4.911 Tue Nov 11 04:26:17 CET 2008
- "port" to threaded perls.
4.91 Mon Nov 10 05:36:38 CET 2008
- the ->throw exception object no longer leaks.
- creating a new cctx leaked a scopestack entry (memleak).
- new coroutines didn't get created with a zero flags field
(unknown impact).
- calling ->throw on a not-yet-started coroutine should now work
instead of being ignored.
- ->throw is now supported on Coro::State objects.
- clean up cctx creation code a bit.
- entersub is actually a UNOP, not a LOGOP (not a bugfix).
4.9 Sat Nov 8 17:45:27 CET 2008
- (libcoro) did not preserve rbp with CORO_ASM (we are getting there).
- (libcoro) no longer leak threads in the experimental pthread backend,
also speed it up considerably.
- (libcoro) do not rely on makecontext passing void *'s unscathed.
- fix compiletime dependencies on libcoro in the Makefile.
- cctx_count wasn't always updated properly.
- Coro::State::cctx_stacksize wasn't applied correctly.
- new function Coro::State::cctx_max_idle.
- the default max number of idle C contexts is now 4.
- (libcoro) try harder to get _setjmp/_longjmp.
- (libcoro) cleanup and extend the libcoro API to officially
allow the creation of empty source contexts.
- very experimental workaround for the totally broken netbsd platform.
- tried to hack around openbsd bugs.
4.804 Wed Nov 5 16:36:00 CET 2008
- Coro::Debug::new_unix_server would not create a non-blocking listening
socket, sometimes causing freezes.
- (libcoro) fix misaligned stack points for setjmp and assembly
methods, which can cause crashes on x86/x86_64 with a sufficiently
aggressive compiler.
- new function: Coro::Debug::new_tcp_server.
- move ->throw into the Coro class because it only works on coro objects.
4.803 Mon Nov 3 17:16:12 CET 2008
- (libcoro) use a global asm statement to become independent of gcc
otpimisations for CORO_ASM (thanks to pippijn for the idea).
- try to workaround yet another broken bsd, this time dragonfly.
4.802 Thu Oct 30 10:56:12 CET 2008
- support -fno-omit-frame-pointer on x86 with the assembly method.
- tune 01_unblock.t tests a bit.
4.801 Wed Oct 22 18:33:37 CEST 2008
- improve readline speed for very long "lines".
- backport to 5.8.8.
4.8 Thu Oct 2 13:34:40 CEST 2008
- new function Coro::AIO::aio_wait.
- Coro.:AIO and Coro::BDB now "use Coro::AnyEvent".
4.47 Sun Apr 6 00:37:52 CEST 2008
- force cctx allocation on API calls: we know we need to force one
and gcc actually manages to confuse our heuristic nowadays,
leading to crashes and worse.
- document force_cctx.
4.46 Fri Apr 4 22:05:43 CEST 2008
- upgrade libcoro, resulting in pthread-backend (which was only created
to fulfill the rules of the programming languages shootout).
4.45 Thu Mar 13 11:55:36 CET 2008
- fix a file leaking bug in eg/mhyttpd that would allow
downloading of any file (reported by oesi).
- fix deadlock bug in Coro::Channel (reported by Richard Hundt)
(also add testcase).
- support Broadcast option in Coro::Socket (patch by Richard Hundt,
apparently having loads of fun with that).
- implement $state->swap_defsv, ->swap_defav and document ->throw.
4.4 Wed Feb 13 16:44:29 CET 2008
- only assume .cfi pseudo isns exist on GNU/Linux.
- add get_timed method to Coro::Channels.
- fixed Coro::Debug manpage.
- perl 5.11 compatbility improvement based on patch by
Andreas König.
4.37 Sun Jan 20 11:25:23 CET 2008
- soften the check for an active parser for perl 5.10 (avoiding
"Coro::State::transfer called while parsing" in many cases).
4.36 Sun Jan 13 10:53:56 CET 2008
- reset diehook when terminating from an async_pool as to not
trigger any __DIE__ handlers.
4.35 Sun Jan 13 04:14:13 CET 2008
- "bt" debug command now displays any exceptions
from longmess and also skips the innermost
stackframes, giving more useufl output.
- allow backtraces in coroutines blocked in Coro::EV,
at a <1% speed hit.
- handle localising of $SIG{__WARN__} and __DIE__
properly (with a proper amount of dirty hacking).
4.34 Sat Dec 22 17:49:53 CET 2007
- upgrade to EV version 2.0 API.
4.33 Mon Dec 17 08:36:12 CET 2007
- make Coro::AIO etc. loadable in the absence of EV.
4.32 Mon Dec 17 07:46:02 CET 2007
- majorly improved Coro::Handle's performance with Coro::EV.
- implemented the until now mythical Coro::BDB module.
- specialcase EV in Coro::AIO and Coro::BDB for extra speed.
4.31 Wed Dec 5 12:32:39 CET 2007
- remove warn statement form Coro::Util.
4.3 Tue Dec 4 20:33:14 CET 2007
- calls to the idle function could cause stack corruption
when the stack changed.
- do no longer rely on the presence of EV::DNS if EV is used
(because it is gone), but instead take avdantage of EV::ADNS
if available.
- add ($) prototypes to all functions in Coro::Storable.
- use a conventional (safer) idle callback in Coro::EV.
- do accept quickly in Coro::Debug to avoid endless loops.
4.22 Fri Nov 30 16:04:04 CET 2007
- really use optimised versions for Event and EV in Coro::Util
and Coro::Handle.
4.21 Sun Nov 25 10:48:59 CET 2007
- fix a spurious memory read.
- Coro::EV no longer keeps the eventloop "alive".
4.2 Fri Nov 9 20:47:05 CET 2007
- enable/disable tracing from a new coroutine, not a pooled one.
- fix a memleak in Coro::Event.
- removed killall call from fork_eval.
- made sure store_fd is already loaded so that fork_eval
does not have to parse autoload in each subprocess.
- only use assembly method if -O switch is in $Config{optimize}.
- add (optional) Coro::EV module, so far the best event loop module
directly supported by Coro.
- if the event model is EV, use EV::DNS to resolve
stuff in Coro::Util.
3.6 Sat Apr 14 17:13:31 CEST 2007
- added some bugfixes to get eg/myhttpd working again.
- added Coro::Storable for often-cede'ing freeze/thaw.
- try to do a clean exit when a coroutine calls exit
(EXPERIMENTAL).
- got rid of indirect call through _coro_init.
- updated the partly antique examples in eg/ to
work again and be a bit less magic, too.
- fixed Coro::Signal semantics to work as documented again.
3.55 Sun Mar 25 01:20:47 CET 2007
- add SAVE_DEFFH to save the default filehandle and enable
it by default.
- finally move socket-operations from Coro::Socket to Coro::Handle
to be able to unblock foreign sockets.
- add Coro::State::save_also and guarded_save.
- add count accessor to Coro::Semaphore.
- add Coro::State::cctx_stacksize.
- just for the fun of it, do not rely on implicit context,
which can dramatically improve performance, but people
using windows-process-emulation perls do not care much about
performance.
3.51 Sun Mar 4 14:18:04 CET 2007
- fixed a problem when you weakened references to Coro::State's
(patch by Yuval Kogman).
3.501 Wed Feb 28 12:44:07 CET 2007
- rename some global symbols as macosx from hell redefines
them without asking.
3.5 Tue Feb 13 20:22:53 CET 2007
- do AnyEvent model detection earlier, avoiding problems
caused by first using AnyEvent and later Coro::Event.
- implement and document Coro::Event event objects.
- fix a potential problem in Coro::Event causing crashes.
- initialise PL_comppad when creating a new coroutine,
avoids crashes on early coro destruction.
3.41 Mon Jan 22 19:19:49 CET 2007
- readline on Coro::Handle did not support undefined $/,
nor did it deliver partial lines on EOF or error.
- implement malloc fallback for stack allocation because
stupid broken idiotic OSX has a stupid broken
idiotic fits-the-whole-os mmap "implementation" and
my dick feels longer if Coro is portable even to
obsolete platforms.
3.4 Fri Jan 19 21:52:54 CET 2007
- remove t/09_timer.t, as it isn't really testing much
but was rather flaky in practise.
- async_pool coro would keep arguments and callback alive until
it was reused.
- cancellation of a coroutine could cause spurious idle calls
in cede_notself.
3.3 Sat Jan 6 03:45:00 CET 2007
- implement $coro->on_destroy.
- Coro::Event blocking semantics have been changed,
documented and - hopefully - improved.
- fix nice adding, not subtracting, from priority.
- fix ->prio and api_is_ready (patch by Mark Hinds).
- fixed an assert ("... == prev__cctx->idle_te")
that could errronously trigger.
- fix various large and small memleaks.
- use a (hopefully) more stable cancel implementation
that immediately frees the coroutine data.
- cede/cede_notself return a status now.
- added Coro::guard function.
- added a global coroutine pool for jobs (on my machine,
I can create and execute 48k simple coros/s with async,
and 128k coros with async_pool).
- Coro::AIO now uses the coroutine priority as io priority.
3.2 Fri Dec 22 05:07:09 CET 2006
- improve portability to slightly older perls.
- use cleaner coroutine destruction.
- simplify configuration for users.
- optionally (unrecommended) prefer perl functions over
their coro replacements.
3.11 Tue Dec 5 13:11:24 CET 2006
- fixed some bogus assert's, but as perl.h disables assert even
without NDEBUG (thank you very much), not too many people should
notice (that did include myself). Andreas König noticed, though :)
- do not save/restore PL_sortcxix on >= 5.9.x, it doesn't seem to have
it. Also noticed by Andreas König :)
- save/restore tainted status.
- verified to pass the testsuite on my 5.9.5.
3.1 Mon Dec 4 23:03:40 CET 2006
- INCOMPATIBLE CHANGE: $/ is now per-coroutine (but slow).
- incompatible change: transfer flags are now per-state.
- give a better error message on deadlock.
- document Coro::nready.
- enhanced testsuite.
3.01 Sun Dec 3 23:47:42 CET 2006
- forgot to include Coro::Timer.
3.0 Sun Dec 3 22:57:25 CET 2006
- the "FINALLY COMPLETELY STABLE" release (coming soon:
the "FAMOUS LAST WORDS" release).
- implement a new stack sharing algorithm, which uses a stack
pool (size currently hardcoded).
- make stack sharing mandatory (it no longer uses a heuristic).
- eval/die no longer cause weird problems under heavy use.
- Coro::Event could cause livelocks if it was used but
no Coro::Event watchers were used.
- Coro::Event now uses asynccheck as prepare does not
check for changed watchers.
- replaced Coro::idle coroutine by (cleaner) idle handler.
- updated to newest libcoro.
- implement enhanced support for valgrind.
- implement is_ready and return value for ready.
- removed Coro::Cont, it was a misnomer (it's generators),
and it was somewhat annoying to get it right. Will come back
if somebody asks for it :)
- many ->wait methods and Coro::Event could return
spuriously without the event having happened.
2.5 Tue Nov 7 12:22:33 CET 2006
- made Coro::Util, Coro::Select, Coro::Handle and Coro::Socket
use AnyEvent, moved them to Coro/.
- added Coro::LWP which contains all the uglyness required to
make LWP non-blocking.
- should work with perl 5.9.x now (Andreas König made me do it).
- fixed another bug in Coro::Select when the timeout was undef.
- reuse PL_start_env for all coros, saves some memory per coroutine.
- manage PL_top_env differently, hopefully to avoid panic: top_env.
- timeout argument was not properly used in Coro::Socket.
- allow limited forms of subclassing in Coro::Handle/Coro::Socket.
- emulate undocumented(!) functionality of IO::Socket required
by LWP(!!).
- updated eg/lwp to work with newer lwp's.
- remove "FATAL: uncaught exception" prefix. Coroutines that die
kill the whole process, just as exceptions in the main "coroutine"
did already.
2.1 Wed Nov 1 23:01:13 CET 2006
- fix a long-standing bug in Coro::Select where select with
zero timeout would instead change the current default filehandle.
- use a simpler and hopefully more robust way to clone padlists
(uses less memory and a perl function instead of our own).
- coro can now create a stack guard area on many architectures.
- Coro::AIO properly reexports additional functions from IO::AIO.
- updated libcoro with a workaround for OS X,
pach and testing by Michael Schwern.
2.0 Tue Oct 24 05:47:17 CEST 2006
- support additional aio requests in Coro::AIO.
1.9 (never properly released due to a glitch)
1.8 Thu Feb 2 00:59:06 CET 2006
- applied suggested patch by SAMV to avoid problems during stupid
mark & sweep gc run.
- applied patch by Scott Walters for 5.9.3 compatibility.
1.7 Tue Dec 27 01:41:58 CET 2005
- added Coro::AIO, a thin wrapper around IO::AIO.
- improved Makefile.PL explanations.
1.6 Mon Dec 12 21:30:05 CET 2005
- additionally save PM_curpm might fix as-of-yet
unseen problems with regex matches being attributed to the
wrong package.
- add t/10_bugs.t, which currently checks against imho broken
perls that use 0.26MB of stack space per Perl_magic_get
invocation (newer linuxes) as opposed to the 0.0002MB perl
normally uses.
- make stacksize configurable for the ultimate debian experience.
1.51 Mon Dec 12 18:48:36 CET 2005
- remove debugging warn() accidentally left in Coro::Select.
1.5 Tue Nov 29 13:32:44 CET 2005
- use Coro::Event inside Coro::Select to avoid spurious deadlocks.
- fix Coro::Select 'select'.
- strict'ify some modules.
- libcoro errornously restored the SIGUSR2 handler to SIGUSR1.
- use XSLoader in selected modules.
- remove some 5.6 compatibility cruft.
1.4 Tue Sep 6 00:11:05 CEST 2005
- libcoro did not take into account the trampoline on amd64,
when 'l'inux method was used.
Coro::State::flush method.
- no longer autodetect windows, present it as an option instead.
1.2 Mon May 16 02:00:55 CEST 2005
- included libcoro.c earlier in State.xs, might improve portability.
- use a faster and possibly more stable Coro::Cont implementation.
- accept x86_64 in addition to amd64 for optimized linux-amd64 support.
- fix bugs Coro::SemaphoreSet that could cause locks never to be freed.
- fix bugs in CoroAPI.h and document it in Coro::MakeMaker.
1.11 Thu Mar 3 18:00:52 CET 2005
- change of contact address.
1.1 Tue Feb 22 20:51:16 CET 2005
- support [l]inux method on amd64.
- allow some context switches while compiling/eval'ing.
1.0 Tue Aug 10 03:47:27 CEST 2004
- Event 0.89 fixes the bug again.
- fix the remaining(??) memleak. I didn't free the cache-AV for
padlists, so one AV per created anon-sub leaked.
0.97 Fri May 14 15:23:32 CEST 2004
- remove stupid gcc extension that was an experiment only anyway.
0.96 Thu May 13 18:09:29 CEST 2004
- tell people if they have yet another broken Event variant.
- made Coro to work _better_ with threads (it seems that, as long
as you use Coros in one thread only everything will work fine.
Looking at the perl source the problem might be missing locking
between Coro and some perl internal routines. That's not easily
fixable).
- (hopefully) got rid of the static xnext inside transfer.
0.95 Sun Feb 15 03:20:28 CET 2004
- removed Coro::State::flush, implemented a new and much
faster caching mechanism by attaching magic to the CV.
- a memleak with (real) closures remains.
- dramatically reduced size of stacks to 65536 (linux/x86), after
observing that even myhttpd never had more than a kilobyte
of stack in use (stack is still only physically allocated in
pagesize increments for systems suporting mmap).
- fix for a "cygwin-64" architecture added, proposed by Stefan Traby.
- fix for threaded perl.
0.9 Sun Nov 23 04:32:39 CET 2003
- fix a few very hard to track down but (of course) stupid
memory leaks.
- stringify version number to avoid locale problems :(.
- perl 5.9.0 does not have SvPADBUSY, reported by Scott Walters,
hopefully ignoring it "just works".
0.8 Wed Nov 5 19:38:40 CET 2003
- port to perl5.005_03, but only 5.8.x+ is supported!
- honor LocalAddr even without LocalPort in Coro::Socket.
0.7 Tue May 27 03:12:38 CEST 2003
- the version jump indicates some level of testing, not gobs
of new features.
- uh... I found the prompt function in ExtUtils::MakeMaker.
Highly correct stuff, that is...
- fixed(?) a bug with die's in coroutines causing "panic: top_env".
the fix is not well understood by the author, so beware :(.
0.652 Thu May 8 02:54:46 CEST 2003
- Applied patch by Slaven Rezic to set default to "s" on FreeBSD,
cause version 4 doesn't have ucontext.
- Benjamin Reed reported that setjmp works fine on darwin,
so preselect it.
0.651 Sat Mar 29 15:00:23 CET 2003
- fix a bug in Coro::Handle where some bytes could get lost
on reading, reported by jason@nichego.net.
0.65 Sun Mar 23 00:08:26 CET 2003
- added a README.linux-glibc.
- new module Coro::Select.
- also save/restore PL_comppad, fixes segfaults with 5.8.1.
(I never claimed that I know what I am doing ;).
- set default to setjmp/longjmp on non-x86-linux.
0.6 Thu Nov 21 11:09:06 CET 2002
- made lazy context switching the default.
- fixed the bug where SemaphoreSet::guard
was the same as timed_guard and timed_guard was missing.
- fix a memleak in Coro::Timer.
- reclassified context sharing as not experimental.
0.534 Sun Apr 14 03:05:12 CEST 2002
- fixed backspace => tab in header parsing (myhttpd).
- added eg/readline, for elmex.
- Coro::Event now calls ->start on first call instead of
->again, which created wrong timeouts for the first ->next.
- fixed a bug where Coro::Socket returned a closed socket instead
of nothing on ECONNREFUSED and similar error conditions.
0.533 Mon Feb 18 18:49:40 CET 2002
- adapt to finally working Event-0.85.
- fixed buggy event initialization (trapped under windows, but how
could it possibly have worked anywhere?)
0.532 Wed Jan 16 02:45:32 CET 2002
- removed the reference to pp_entersub, might work on
(some) win32 perls now (testsuite works under cygwin,
without Event, which freezes).
0.531 Mon Dec 10 22:18:44 CET 2001
- Fixed a bug in SemaphoreSet::timed_down.
0.53 Tue Nov 27 21:11:13 CET 2001
- some tests for Event.
- slightly different internal architecture to get refcnt into the object
and not the reference. might fix a few bugs, certainly did introduce
new ones.
- Coro::Timer (independent of Event).
- new timed_wait functions for Coro::Signal, Semaphore, SemaphoreSet.
0.52 Tue Nov 6 21:36:18 CET 2001
- ported to cygwin (trivial).
patch by Gerrit P. Haase <gp@familiehaase.de>.
- small setjmp code fix by Sullivan.DanielJ@epamail.epa.gov.
0.51 Thu Nov 1 20:39:01 CET 2001
- terminate/cancel now work properly (otherwise termination
could cause a "next coroutine is not and contains not..."
error.
- added Coro::Socket::shutdown.
- Coro::Event::loop no is the same as Event::loop.
- implemented terminate with args + join.
0.5 Fri Sep 28 16:15:35 CEST 2001
- fixed "print" on a Coro::Handle. The print method worked.
- small tweaks (seem to reduce memory consumption a lot)
( run in 1.253 second using v1.01-cache-2.11-cpan-49f99fa48dc )
