2 2
3TODO: better (earlier) error messages on broken transfer's 3TODO: should explore PerlIO::via::CoroCede and PerlIO::via::CoroAIO.
4TODO: "internals mode" 4TODO: maybe implement a default message channel, very much like Erlang's
5TODO: "use defaults for everything" 5 actor model (which is cool in a lot of important aspects (failures!),
6 but very lacking in others (higher level ipc)).
6 7
8 TODO: Coro::AnyEvent
9 - implement cancel, ready and kill commands in Coro::Debug.
10 - document find_coro in Coro::Debug.
11
124.6 Sat Apr 26 10:05:14 CEST 2008
13 - INCOMPATIBLE CHANGE: sub/code attributes are no longer supported
14 by the Coro module. It was a mistake to have it in the first place.
15 - (experimental) support for activestate perl 5.10 (method "w").
16 - (experimental) support for strawberry perl (method "a").
17 - coro_sigelem_set did not return a value although it had to,
18 actual impact unknown.
19
204.51 Mon Apr 14 13:28:27 CEST 2008
21 - make it compile again on 5.8.
22
234.50 Thu Apr 10 09:43:17 CEST 2008
24 - I did it twice! (see 4.49).
25
264.49 Sun Apr 6 21:23:31 CEST 2008
27 - grr, instead of compiling the recent changes on 5.10 only they
28 were compiled on 5.8 only.
29
304.48 Sun Apr 6 20:36:46 CEST 2008
31 - allow coroutine switches during eval's under 5.10.x, as it seems
32 the parser is a per-interpreter option now, so this is safe
33 (this might fix the odd crashing bug).
34 - drop support for 5.9.x versions: they are dead, jim.
35
364.47 Sun Apr 6 00:37:52 CEST 2008
37 - force cctx allocation on API calls: we know we need to force one
38 and gcc actually manages to confuse our heuristic nowadays,
39 leading to crashes and worse.
40 - document force_cctx.
41
424.46 Fri Apr 4 22:05:43 CEST 2008
43 - upgrade libcoro, resulting in pthread-backend (which was only created
44 to fulfill the rules of the programming languages shootout).
45
464.45 Thu Mar 13 11:55:36 CET 2008
47 - fix a file leaking bug in eg/mhyttpd that would allow
48 downloading of any file (reported by oesi).
49 - fix deadlock bug in Coro::Channel (reported by Richard Hundt)
50 (also add testcase).
51 - support Broadcast option in Coro::Socket (patch by Richard Hundt,
52 apparently having loads of fun with that).
53 - implement $state->swap_defsv, ->swap_defav and document ->throw.
54
554.4 Wed Feb 13 16:44:29 CET 2008
56 - only assume .cfi pseudo isns exist on GNU/Linux.
57 - add get_timed method to Coro::Channels.
58 - fixed Coro::Debug manpage.
59 - perl 5.11 compatbility improvement based on patch by
60 Andreas König.
61
624.37 Sun Jan 20 11:25:23 CET 2008
63 - soften the check for an active parser for perl 5.10 (avoiding
64 "Coro::State::transfer called while parsing" in many cases).
65
664.36 Sun Jan 13 10:53:56 CET 2008
67 - reset diehook when terminating from an async_pool as to not
68 trigger any __DIE__ handlers.
69
704.35 Sun Jan 13 04:14:13 CET 2008
71 - "bt" debug command now displays any exceptions
72 from longmess and also skips the innermost
73 stackframes, giving more useufl output.
74 - allow backtraces in coroutines blocked in Coro::EV,
75 at a <1% speed hit.
76 - handle localising of $SIG{__WARN__} and __DIE__
77 properly (with a proper amount of dirty hacking).
78
794.34 Sat Dec 22 17:49:53 CET 2007
80 - upgrade to EV version 2.0 API.
81
824.33 Mon Dec 17 08:36:12 CET 2007
83 - make Coro::AIO etc. loadable in the absence of EV.
84
854.32 Mon Dec 17 07:46:02 CET 2007
86 - majorly improved Coro::Handle's performance with Coro::EV.
87 - implemented the until now mythical Coro::BDB module.
88 - specialcase EV in Coro::AIO and Coro::BDB for extra speed.
89
904.31 Wed Dec 5 12:32:39 CET 2007
91 - remove warn statement form Coro::Util.
92
934.3 Tue Dec 4 20:33:14 CET 2007
94 - calls to the idle function could cause stack corruption
95 when the stack changed.
96 - do no longer rely on the presence of EV::DNS if EV is used
97 (because it is gone), but instead take avdantage of EV::ADNS
98 if available.
99 - add ($) prototypes to all functions in Coro::Storable.
100 - use a conventional (safer) idle callback in Coro::EV.
101 - do accept quickly in Coro::Debug to avoid endless loops.
102
1034.22 Fri Nov 30 16:04:04 CET 2007
104 - really use optimised versions for Event and EV in Coro::Util
105 and Coro::Handle.
106
1074.21 Sun Nov 25 10:48:59 CET 2007
108 - fix a spurious memory read.
109 - Coro::EV no longer keeps the eventloop "alive".
110
1114.2 Fri Nov 9 20:47:05 CET 2007
112 - enable/disable tracing from a new coroutine, not a pooled one.
113 - fix a memleak in Coro::Event.
114 - removed killall call from fork_eval.
115 - made sure store_fd is already loaded so that fork_eval
116 does not have to parse autoload in each subprocess.
117 - only use assembly method if -O switch is in $Config{optimize}.
118 - add (optional) Coro::EV module, so far the best event loop module
119 directly supported by Coro.
120 - if the event model is EV, use EV::DNS to resolve
121 stuff in Coro::Util.
122 - don't get confused by multiple event notifications in Coro::Handle.
123 - initial support for EV (libevent interface).
124 - require Event and EV using configure_requires, to force their existance.
125
1264.13 Wed Oct 24 07:26:45 CEST 2007
127 - add Coro::Storable::blocking_thaw.
128 - use a vastly more complicated technique to localise
129 $SIG{__WARN/DIE__} that also works on perls <= 5.8.8.
130 - use a coroutine for the idle callback Coro::Event,
131 instead of running Event in the current coroutine context.
132 This also catches recursive invocations.
133 - actually report fork errors in gethostbyname and inet_aton.
134
1354.11 Thu Oct 11 02:40:24 CEST 2007
136 - port to threaded perls.
137
1384.1 Thu Oct 11 02:38:16 CEST 2007
139 - incompatible change: $SIG{__DIE__} and $SIG{__WARN__} will now
140 be local to each coro (see Coro::State).
141 - incompatible change: for very deep reasons, cede and cede_notself
142 cannot return anything, so nothing will be returned.
143 - possibly bring back 5.10 compatibility (untested).
144 - work around stupid (and wrong) warning on 5.10 :(.
145 - overlay the saved state over the context stack. This saves
146 a few hundred bytes per coroutine on average and also
147 speeds up context switching a bit.
148 - further tune default stack sizes.
149 - (more) correctly calculate stack usage in coro_rss.
150 - Coro::Storable::blocking_* did not properly lock
151 resulting in races between coroutines.
152 - added Coro::Storable::guard.
153 - stopping to trace a coroutine could destroy the cctx of
154 an unrelated coroutine.
155 - explain the relationship between Perl and C coroutines in
156 more detail in Coro::State.
157 - Coro::Util::inet_aton did not short-circuit dotted quad forms,
158 causing a fork per resolve. This also affected Coro::Socket.
159 - switch to a separate stack in $coro->call/eval to avoid
160 invalidating pointers.
161
1624.03 Sat Oct 6 21:24:00 CEST 2007
163 - added Coro::throw method.
164 - minor code cleanups.
165
1664.02 Sat Oct 6 02:36:47 CEST 2007
167 - fix a very minor per-coroutine memleak (a single codereference).
168 - fixed a bug where the currently in-use c context would be freed
169 prematurely (can happen only when programs change the stacksize
170 or use tracing).
171 - tracing can no longer keep a coro alive after it terminated.
172 - do static branch prediction in the common path for gcc. gives
173 about 2-5% speed improvement here.
174
1754.01 Fri Oct 5 22:10:49 CEST 2007
176 - instead of recreating *a* standard output handle we simply
177 use STDOUT, which is faster and hopefully more robust.
178
1794.0 Fri Oct 5 12:56:00 CEST 2007
180 - incompatibly changed Coro::Storable::freeze.
181 - major new feature: added Coro::Debug, for interactive coroutine
182 debugging, tracing and much more.
183 - major bug fix: unbelievable, but true: $_, $/ and many other
184 "saved" variables actually weren't being saved. This has been fixed,
185 of course, while increasing performance while losing all the save
186 flags.
187 - save flags are gone, and all the api functions dealing with them.
188 - added Coro::Semaphore::adjust.
189 - added Coro::Util::fork_eval.
190 - added Coro::Storable::{nfreeze,blocking_{freeze,nfreeze}}.
191 - added Coro::killall.
192 - reduce initial stack sizes to allow for "micro-coroutines".
193 - better async_pool resource management, moved parts of async_pool
194 handling to XS (major speed improvement).
195 - actually croak before modifying important data structures.
196 - refuse to transfer while compiling.
197 - possibly support eval EXPR better now.
198 - enable assembly per default on linux+bsd x86+amd64.
199 - all internal members were renamed _something for easier subclassing.
200 - many minor tweaks.
201
2023.63 Wed May 16 14:10:06 CEST 2007
203 - implement handcoded assembly for x86/amd64 SVR ABI.
204
2053.62 Fri Apr 27 21:36:06 CEST 2007
206 - upgrade libcoro (which might set unwind info correctly).
207 - change default on linux to setjmp/longjmp.
208
2093.61 Thu Apr 19 12:36:18 CEST 2007
210 - Coro::Storable caused an endless loop when thawing invalid
211 pst's sometimes.
212 - use a Semaphore in Coro::Storable, as Storable doesn't
213 seem to be reentrant (although it is documented to
214 be threadsafe...).
215 - fix Coro::Signal to bring back the original unreliable
216 but stateful semantics.
217 - fixed a lot of typos in Coro.pm (patch submitted by David
218 Steinbrunner, which applied flawlessly).
219
2203.6 Sat Apr 14 17:13:31 CEST 2007
221 - added some bugfixes to get eg/myhttpd working again.
222 - added Coro::Storable for often-cede'ing freeze/thaw.
223 - try to do a clean exit when a coroutine calls exit
224 (EXPERIMENTAL).
225 - got rid of indirect call through _coro_init.
226 - updated the partly antique examples in eg/ to
227 work again and be a bit less magic, too.
228 - fixed Coro::Signal semantics to work as documented again.
229
2303.55 Sun Mar 25 01:20:47 CET 2007
231 - add SAVE_DEFFH to save the default filehandle and enable
232 it by default.
233 - finally move socket-operations from Coro::Socket to Coro::Handle
234 to be able to unblock foreign sockets.
235 - add Coro::State::save_also and guarded_save.
236 - add count accessor to Coro::Semaphore.
237 - add Coro::State::cctx_stacksize.
238 - just for the fun of it, do not rely on implicit context,
239 which can dramatically improve performance, but people
240 using windows-process-emulation perls do not care much about
241 performance.
242
2433.51 Sun Mar 4 14:18:04 CET 2007
244 - fixed a problem when you weakened references to Coro::State's
245 (patch by Yuval Kogman).
246
2473.501 Wed Feb 28 12:44:07 CET 2007
248 - rename some global symbols as macosx from hell redefines
249 them without asking.
250
2513.5 Tue Feb 13 20:22:53 CET 2007
252 - do AnyEvent model detection earlier, avoiding problems
253 caused by first using AnyEvent and later Coro::Event.
254 - implement and document Coro::Event event objects.
255 - fix a potential problem in Coro::Event causing crashes.
256 - initialise PL_comppad when creating a new coroutine,
257 avoids crashes on early coro destruction.
258
2593.41 Mon Jan 22 19:19:49 CET 2007
260 - readline on Coro::Handle did not support undefined $/,
261 nor did it deliver partial lines on EOF or error.
262 - implement malloc fallback for stack allocation because
263 stupid broken idiotic OSX has a stupid broken
264 idiotic fits-the-whole-os mmap "implementation" and
265 my dick feels longer if Coro is portable even to
266 obsolete platforms.
267
2683.4 Fri Jan 19 21:52:54 CET 2007
269 - remove t/09_timer.t, as it isn't really testing much
270 but was rather flaky in practise.
271 - async_pool coro would keep arguments and callback alive until
272 it was reused.
273 - cancellation of a coroutine could cause spurious idle calls
274 in cede_notself.
275
2763.3 Sat Jan 6 03:45:00 CET 2007
277 - implement $coro->on_destroy.
278 - Coro::Event blocking semantics have been changed,
279 documented and - hopefully - improved.
280 - fix nice adding, not subtracting, from priority.
281 - fix ->prio and api_is_ready (patch by Mark Hinds).
282 - fixed an assert ("... == prev__cctx->idle_te")
283 that could errronously trigger.
284 - fix various large and small memleaks.
285 - use a (hopefully) more stable cancel implementation
286 that immediately frees the coroutine data.
287 - cede/cede_notself return a status now.
288 - added Coro::guard function.
289 - added a global coroutine pool for jobs (on my machine,
290 I can create and execute 48k simple coros/s with async,
291 and 128k coros with async_pool).
292 - Coro::AIO now uses the coroutine priority as io priority.
293
2943.2 Fri Dec 22 05:07:09 CET 2006
7 - improve portability to slightly older perls. 295 - improve portability to slightly older perls.
8 - use cleaner coroutine destruction. 296 - use cleaner coroutine destruction.
297 - simplify configuration for users.
298 - optionally (unrecommended) prefer perl functions over
299 their coro replacements.

103.11 Tue Dec 5 13:11:24 CET 2006 3013.11 Tue Dec 5 13:11:24 CET 2006
11 - fixed some bogus assert's, but as perl.h disables assert even 302 - fixed some bogus assert's, but as perl.h disables assert even
