3TODO: check wether stack-sharing is still effective 3TODO: should explore PerlIO::via::CoroCede and PerlIO::via::CoroAIO.
4TODO: more effective stack sharing by having one "default stack" for "simple" coroutines? 4TODO: maybe implement a default message channel, very much like Erlang
5TODO: verify exception frame changes and force stack copies? 5 (which is cool in a lot of important aspects (failures!),
6 but very lacking in others (higher level ipc)).
6 7
8 - fix a file leaking bug in eg/mhyttpd that would allow
9 downloading of any file (reported by oesi).
10 - support Broadcast option in Coro::Socket (patch by Richard Hundt,
11 apparently having loads of fun with that).
12
134.4 Wed Feb 13 16:44:29 CET 2008
14 - only assume .cfi pseudo isns exist on GNU/Linux.
15 - add get_timed method to Coro::Channels.
16 - fixed Coro::Debug manpage.
17 - perl 5.11 compatbility improvement based on patch by
18 Andreas König.
19
204.37 Sun Jan 20 11:25:23 CET 2008
21 - soften the check for an active parser for perl 5.10 (avoiding
22 "Coro::State::transfer called while parsing" in many cases).
23
244.36 Sun Jan 13 10:53:56 CET 2008
25 - reset diehook when terminating from an async_pool as to not
26 trigger any __DIE__ handlers.
27
284.35 Sun Jan 13 04:14:13 CET 2008
29 - "bt" debug command now displays any exceptions
30 from longmess and also skips the innermost
31 stackframes, giving more useufl output.
32 - allow backtraces in coroutines blocked in Coro::EV,
33 at a <1% speed hit.
34 - handle localising of $SIG{__WARN__} and __DIE__
35 properly (with a proper amount of dirty hacking).
36
374.34 Sat Dec 22 17:49:53 CET 2007
38 - upgrade to EV version 2.0 API.
39
404.33 Mon Dec 17 08:36:12 CET 2007
41 - make Coro::AIO etc. loadable in the absence of EV.
42
434.32 Mon Dec 17 07:46:02 CET 2007
44 - majorly improved Coro::Handle's performance with Coro::EV.
45 - implemented the until now mythical Coro::BDB module.
46 - specialcase EV in Coro::AIO and Coro::BDB for extra speed.
47
484.31 Wed Dec 5 12:32:39 CET 2007
49 - remove warn statement form Coro::Util.
50
514.3 Tue Dec 4 20:33:14 CET 2007
52 - calls to the idle function could cause stack corruption
53 when the stack changed.
54 - do no longer rely on the presence of EV::DNS if EV is used
55 (because it is gone), but instead take avdantage of EV::ADNS
56 if available.
57 - add ($) prototypes to all functions in Coro::Storable.
58 - use a conventional (safer) idle callback in Coro::EV.
59 - do accept quickly in Coro::Debug to avoid endless loops.
60
614.22 Fri Nov 30 16:04:04 CET 2007
62 - really use optimised versions for Event and EV in Coro::Util
63 and Coro::Handle.
64
654.21 Sun Nov 25 10:48:59 CET 2007
66 - fix a spurious memory read.
67 - Coro::EV no longer keeps the eventloop "alive".
68
694.2 Fri Nov 9 20:47:05 CET 2007
70 - enable/disable tracing from a new coroutine, not a pooled one.
71 - fix a memleak in Coro::Event.
72 - removed killall call from fork_eval.
73 - made sure store_fd is already loaded so that fork_eval
74 does not have to parse autoload in each subprocess.
75 - only use assembly method if -O switch is in $Config{optimize}.
76 - add (optional) Coro::EV module, so far the best event loop module
77 directly supported by Coro.
78 - if the event model is EV, use EV::DNS to resolve
79 stuff in Coro::Util.
80 - don't get confused by multiple event notifications in Coro::Handle.
81 - initial support for EV (libevent interface).
82 - require Event and EV using configure_requires, to force their existance.
83
844.13 Wed Oct 24 07:26:45 CEST 2007
85 - add Coro::Storable::blocking_thaw.
86 - use a vastly more complicated technique to localise
87 $SIG{__WARN/DIE__} that also works on perls <= 5.8.8.
88 - use a coroutine for the idle callback Coro::Event,
89 instead of running Event in the current coroutine context.
90 This also catches recursive invocations.
91 - actually report fork errors in gethostbyname and inet_aton.
92
934.11 Thu Oct 11 02:40:24 CEST 2007
94 - port to threaded perls.
95
964.1 Thu Oct 11 02:38:16 CEST 2007
97 - incompatible change: $SIG{__DIE__} and $SIG{__WARN__} will now
98 be local to each coro (see Coro::State).
99 - incompatible change: for very deep reasons, cede and cede_notself
100 cannot return anything, so nothing will be returned.
101 - possibly bring back 5.10 compatibility (untested).
102 - work around stupid (and wrong) warning on 5.10 :(.
103 - overlay the saved state over the context stack. This saves
104 a few hundred bytes per coroutine on average and also
105 speeds up context switching a bit.
106 - further tune default stack sizes.
107 - (more) correctly calculate stack usage in coro_rss.
108 - Coro::Storable::blocking_* did not properly lock
109 resulting in races between coroutines.
110 - added Coro::Storable::guard.
111 - stopping to trace a coroutine could destroy the cctx of
112 an unrelated coroutine.
113 - explain the relationship between Perl and C coroutines in
114 more detail in Coro::State.
115 - Coro::Util::inet_aton did not short-circuit dotted quad forms,
116 causing a fork per resolve. This also affected Coro::Socket.
117 - switch to a separate stack in $coro->call/eval to avoid
118 invalidating pointers.
119
1204.03 Sat Oct 6 21:24:00 CEST 2007
121 - added Coro::throw method.
122 - minor code cleanups.
123
1244.02 Sat Oct 6 02:36:47 CEST 2007
125 - fix a very minor per-coroutine memleak (a single codereference).
126 - fixed a bug where the currently in-use c context would be freed
127 prematurely (can happen only when programs change the stacksize
128 or use tracing).
129 - tracing can no longer keep a coro alive after it terminated.
130 - do static branch prediction in the common path for gcc. gives
131 about 2-5% speed improvement here.
132
1334.01 Fri Oct 5 22:10:49 CEST 2007
134 - instead of recreating *a* standard output handle we simply
135 use STDOUT, which is faster and hopefully more robust.
136
1374.0 Fri Oct 5 12:56:00 CEST 2007
138 - incompatibly changed Coro::Storable::freeze.
139 - major new feature: added Coro::Debug, for interactive coroutine
140 debugging, tracing and much more.
141 - major bug fix: unbelievable, but true: $_, $/ and many other
142 "saved" variables actually weren't being saved. This has been fixed,
143 of course, while increasing performance while losing all the save
144 flags.
145 - save flags are gone, and all the api functions dealing with them.
146 - added Coro::Semaphore::adjust.
147 - added Coro::Util::fork_eval.
148 - added Coro::Storable::{nfreeze,blocking_{freeze,nfreeze}}.
149 - added Coro::killall.
150 - reduce initial stack sizes to allow for "micro-coroutines".
151 - better async_pool resource management, moved parts of async_pool
152 handling to XS (major speed improvement).
153 - actually croak before modifying important data structures.
154 - refuse to transfer while compiling.
155 - possibly support eval EXPR better now.
156 - enable assembly per default on linux+bsd x86+amd64.
157 - all internal members were renamed _something for easier subclassing.
158 - many minor tweaks.
159
1603.63 Wed May 16 14:10:06 CEST 2007
161 - implement handcoded assembly for x86/amd64 SVR ABI.
162
1633.62 Fri Apr 27 21:36:06 CEST 2007
164 - upgrade libcoro (which might set unwind info correctly).
165 - change default on linux to setjmp/longjmp.
166
1673.61 Thu Apr 19 12:36:18 CEST 2007
168 - Coro::Storable caused an endless loop when thawing invalid
169 pst's sometimes.
170 - use a Semaphore in Coro::Storable, as Storable doesn't
171 seem to be reentrant (although it is documented to
172 be threadsafe...).
173 - fix Coro::Signal to bring back the original unreliable
174 but stateful semantics.
175 - fixed a lot of typos in Coro.pm (patch submitted by David
176 Steinbrunner, which applied flawlessly).
177
1783.6 Sat Apr 14 17:13:31 CEST 2007
179 - added some bugfixes to get eg/myhttpd working again.
180 - added Coro::Storable for often-cede'ing freeze/thaw.
181 - try to do a clean exit when a coroutine calls exit
182 (EXPERIMENTAL).
183 - got rid of indirect call through _coro_init.
184 - updated the partly antique examples in eg/ to
185 work again and be a bit less magic, too.
186 - fixed Coro::Signal semantics to work as documented again.
187
1883.55 Sun Mar 25 01:20:47 CET 2007
189 - add SAVE_DEFFH to save the default filehandle and enable
190 it by default.
191 - finally move socket-operations from Coro::Socket to Coro::Handle
192 to be able to unblock foreign sockets.
193 - add Coro::State::save_also and guarded_save.
194 - add count accessor to Coro::Semaphore.
195 - add Coro::State::cctx_stacksize.
196 - just for the fun of it, do not rely on implicit context,
197 which can dramatically improve performance, but people
198 using windows-process-emulation perls do not care much about
199 performance.
200
2013.51 Sun Mar 4 14:18:04 CET 2007
202 - fixed a problem when you weakened references to Coro::State's
203 (patch by Yuval Kogman).
204
2053.501 Wed Feb 28 12:44:07 CET 2007
206 - rename some global symbols as macosx from hell redefines
207 them without asking.
208
2093.5 Tue Feb 13 20:22:53 CET 2007
210 - do AnyEvent model detection earlier, avoiding problems
211 caused by first using AnyEvent and later Coro::Event.
212 - implement and document Coro::Event event objects.
213 - fix a potential problem in Coro::Event causing crashes.
214 - initialise PL_comppad when creating a new coroutine,
215 avoids crashes on early coro destruction.
216
2173.41 Mon Jan 22 19:19:49 CET 2007
218 - readline on Coro::Handle did not support undefined $/,
219 nor did it deliver partial lines on EOF or error.
220 - implement malloc fallback for stack allocation because
221 stupid broken idiotic OSX has a stupid broken
222 idiotic fits-the-whole-os mmap "implementation" and
223 my dick feels longer if Coro is portable even to
224 obsolete platforms.
225
2263.4 Fri Jan 19 21:52:54 CET 2007
227 - remove t/09_timer.t, as it isn't really testing much
228 but was rather flaky in practise.
229 - async_pool coro would keep arguments and callback alive until
230 it was reused.
231 - cancellation of a coroutine could cause spurious idle calls
232 in cede_notself.
233
2343.3 Sat Jan 6 03:45:00 CET 2007
235 - implement $coro->on_destroy.
236 - Coro::Event blocking semantics have been changed,
237 documented and - hopefully - improved.
238 - fix nice adding, not subtracting, from priority.
239 - fix ->prio and api_is_ready (patch by Mark Hinds).
240 - fixed an assert ("... == prev__cctx->idle_te")
241 that could errronously trigger.
242 - fix various large and small memleaks.
243 - use a (hopefully) more stable cancel implementation
244 that immediately frees the coroutine data.
245 - cede/cede_notself return a status now.
246 - added Coro::guard function.
247 - added a global coroutine pool for jobs (on my machine,
248 I can create and execute 48k simple coros/s with async,
249 and 128k coros with async_pool).
250 - Coro::AIO now uses the coroutine priority as io priority.
251
2523.2 Fri Dec 22 05:07:09 CET 2006
253 - improve portability to slightly older perls.
254 - use cleaner coroutine destruction.
255 - simplify configuration for users.
256 - optionally (unrecommended) prefer perl functions over
257 their coro replacements.
258
2593.11 Tue Dec 5 13:11:24 CET 2006
260 - fixed some bogus assert's, but as perl.h disables assert even
261 without NDEBUG (thank you very much), not too many people should
262 notice (that did include myself). Andreas König noticed, though :)
263 - do not save/restore PL_sortcxix on >= 5.9.x, it doesn't seem to have
264 it. Also noticed by Andreas König :)
265 - save/restore tainted status.
266 - verified to pass the testsuite on my 5.9.5.
267
2683.1 Mon Dec 4 23:03:40 CET 2006
269 - INCOMPATIBLE CHANGE: $/ is now per-coroutine (but slow).
270 - incompatible change: transfer flags are now per-state.
271 - give a better error message on deadlock.
272 - document Coro::nready.
273 - enhanced testsuite.
274
2753.01 Sun Dec 3 23:47:42 CET 2006
276 - forgot to include Coro::Timer.
277
2783.0 Sun Dec 3 22:57:25 CET 2006
279 - the "FINALLY COMPLETELY STABLE" release (coming soon:
280 the "FAMOUS LAST WORDS" release).
7 - reimplement a new stack sharing algorithm. 281 - implement a new stack sharing algorithm, which uses a stack
282 pool (size currently hardcoded).
8 - make stack sharing mandatory (it no longer uses a heuristic). 283 - make stack sharing mandatory (it no longer uses a heuristic).
284 - eval/die no longer cause weird problems under heavy use.
9 - Coro::Event could cause livelocks if it was used but 285 - Coro::Event could cause livelocks if it was used but
10 Event watchers were used directly. 286 no Coro::Event watchers were used.
287 - Coro::Event now uses asynccheck as prepare does not
288 check for changed watchers.
289 - Coro::Event allows multiple waiting coros and will wake up one
290 per event.
11 - Coro::Event should be cleaner and more efficient now. 291 - Coro::Event should be cleaner and more efficient now.
292 - new utility function Coro::unblock_sub.
293 - document the sad fact that Event is no longer reentrant.
294 - putting a coroutine into the ready queue twice could under
295 some circumstances lead to stack corruption.
12 - minor incompatibility: subclassing is supported directly now 296 - minor incompatibility: subclassing Coro::State is supported
13 without going through a _coro_state member. 297 directly now without going through a _coro_state member.
14 - process swicthing is much faster now. 298 - state/coro switching is much faster now.
15 - very minor optimisations and code/documentation cleanup. 299 - very minor optimisations and code/documentation cleanup.
16 - avoid problems due to compiler inlining. 300 - avoid problems due to compiler inlining.
17 - possibly better support for threads.
18 - removed timers from Coro::Timer -> use AnyEvent instead. 301 - removed timers from Coro::Timer -> use AnyEvent instead.
19 - replaced Coro::idle coroutine by (cleaner) idle handler. 302 - replaced Coro::idle coroutine by (cleaner) idle handler.
303 - updated to newest libcoro.
304 - implement enhanced support for valgrind.
305 - implement is_ready and return value for ready.
306 - removed Coro::Cont, it was a misnomer (it's generators),
307 and it was somewhat annoying to get it right. Will come back
308 if somebody asks for it :)
309 - many ->wait methods and Coro::Event could return
310 spuriously without the event having happened.
20 311
212.5 Tue Nov 7 12:22:33 CET 2006 3122.5 Tue Nov 7 12:22:33 CET 2006
22 - made Coro::Util, Coro::Select, Coro::Handle and Coro::Socket 313 - made Coro::Util, Coro::Select, Coro::Handle and Coro::Socket
23 use AnyEvent, moved them to Coro/. 314 use AnyEvent, moved them to Coro/.
24 - added Coro::LWP which contains all the uglyness required to 315 - added Coro::LWP which contains all the uglyness required to
