2 2
3TODO: better (earlier) error messages on broken transfer's 3TODO: should explore PerlIO::via::CoroCede and PerlIO::via::CoroAIO.
4TODO: destroy gets only called on cancel: fix(?) 4TODO: maybe implement a default message channel, very much like Erlang's
5 actor model (which is cool in a lot of important aspects (failures!),
6 but very lacking in others (higher level ipc)).
5 7
63.3 8 TODO: Coro::AnyEvent
9 - completely reworked the Coro manpage.
10 - added Coro::AnyEvent, generic event loop integration.
11 - implement cancel, ready and kill commands in Coro::Debug.
12 - document find_coro in Coro::Debug.
13 - incompatible change: rename has_stack to has_cctx.
14
154.6 Sat Apr 26 10:05:14 CEST 2008
16 - INCOMPATIBLE CHANGE: sub/code attributes are no longer supported
17 by the Coro module. It was a mistake to have it in the first place.
18 - (experimental) support for activestate perl 5.10 (method "w").
19 - (experimental) support for strawberry perl (method "a").
20 - coro_sigelem_set did not return a value although it had to,
21 actual impact unknown.
22
234.51 Mon Apr 14 13:28:27 CEST 2008
24 - make it compile again on 5.8.
25
264.50 Thu Apr 10 09:43:17 CEST 2008
27 - I did it twice! (see 4.49).
28
294.49 Sun Apr 6 21:23:31 CEST 2008
30 - grr, instead of compiling the recent changes on 5.10 only they
31 were compiled on 5.8 only.
32
334.48 Sun Apr 6 20:36:46 CEST 2008
34 - allow coroutine switches during eval's under 5.10.x, as it seems
35 the parser is a per-interpreter option now, so this is safe
36 (this might fix the odd crashing bug).
37 - drop support for 5.9.x versions: they are dead, jim.
38
394.47 Sun Apr 6 00:37:52 CEST 2008
40 - force cctx allocation on API calls: we know we need to force one
41 and gcc actually manages to confuse our heuristic nowadays,
42 leading to crashes and worse.
43 - document force_cctx.
44
454.46 Fri Apr 4 22:05:43 CEST 2008
46 - upgrade libcoro, resulting in pthread-backend (which was only created
47 to fulfill the rules of the programming languages shootout).
48
494.45 Thu Mar 13 11:55:36 CET 2008
50 - fix a file leaking bug in eg/mhyttpd that would allow
51 downloading of any file (reported by oesi).
52 - fix deadlock bug in Coro::Channel (reported by Richard Hundt)
53 (also add testcase).
54 - support Broadcast option in Coro::Socket (patch by Richard Hundt,
55 apparently having loads of fun with that).
56 - implement $state->swap_defsv, ->swap_defav and document ->throw.
57
584.4 Wed Feb 13 16:44:29 CET 2008
59 - only assume .cfi pseudo isns exist on GNU/Linux.
60 - add get_timed method to Coro::Channels.
61 - fixed Coro::Debug manpage.
62 - perl 5.11 compatbility improvement based on patch by
63 Andreas König.
64
654.37 Sun Jan 20 11:25:23 CET 2008
66 - soften the check for an active parser for perl 5.10 (avoiding
67 "Coro::State::transfer called while parsing" in many cases).
68
694.36 Sun Jan 13 10:53:56 CET 2008
70 - reset diehook when terminating from an async_pool as to not
71 trigger any __DIE__ handlers.
72
734.35 Sun Jan 13 04:14:13 CET 2008
74 - "bt" debug command now displays any exceptions
75 from longmess and also skips the innermost
76 stackframes, giving more useufl output.
77 - allow backtraces in coroutines blocked in Coro::EV,
78 at a <1% speed hit.
79 - handle localising of $SIG{__WARN__} and __DIE__
80 properly (with a proper amount of dirty hacking).
81
824.34 Sat Dec 22 17:49:53 CET 2007
83 - upgrade to EV version 2.0 API.
84
854.33 Mon Dec 17 08:36:12 CET 2007
86 - make Coro::AIO etc. loadable in the absence of EV.
87
884.32 Mon Dec 17 07:46:02 CET 2007
89 - majorly improved Coro::Handle's performance with Coro::EV.
90 - implemented the until now mythical Coro::BDB module.
91 - specialcase EV in Coro::AIO and Coro::BDB for extra speed.
92
934.31 Wed Dec 5 12:32:39 CET 2007
94 - remove warn statement form Coro::Util.
95
964.3 Tue Dec 4 20:33:14 CET 2007
97 - calls to the idle function could cause stack corruption
98 when the stack changed.
99 - do no longer rely on the presence of EV::DNS if EV is used
100 (because it is gone), but instead take avdantage of EV::ADNS
101 if available.
102 - add ($) prototypes to all functions in Coro::Storable.
103 - use a conventional (safer) idle callback in Coro::EV.
104 - do accept quickly in Coro::Debug to avoid endless loops.
105
1064.22 Fri Nov 30 16:04:04 CET 2007
107 - really use optimised versions for Event and EV in Coro::Util
108 and Coro::Handle.
109
1104.21 Sun Nov 25 10:48:59 CET 2007
111 - fix a spurious memory read.
112 - Coro::EV no longer keeps the eventloop "alive".
113
1144.2 Fri Nov 9 20:47:05 CET 2007
115 - enable/disable tracing from a new coroutine, not a pooled one.
116 - fix a memleak in Coro::Event.
117 - removed killall call from fork_eval.
118 - made sure store_fd is already loaded so that fork_eval
119 does not have to parse autoload in each subprocess.
120 - only use assembly method if -O switch is in $Config{optimize}.
121 - add (optional) Coro::EV module, so far the best event loop module
122 directly supported by Coro.
123 - if the event model is EV, use EV::DNS to resolve
124 stuff in Coro::Util.
125 - don't get confused by multiple event notifications in Coro::Handle.
126 - initial support for EV (libevent interface).
127 - require Event and EV using configure_requires, to force their existance.
128
1294.13 Wed Oct 24 07:26:45 CEST 2007
130 - add Coro::Storable::blocking_thaw.
131 - use a vastly more complicated technique to localise
132 $SIG{__WARN/DIE__} that also works on perls <= 5.8.8.
133 - use a coroutine for the idle callback Coro::Event,
134 instead of running Event in the current coroutine context.
135 This also catches recursive invocations.
136 - actually report fork errors in gethostbyname and inet_aton.
137
1384.11 Thu Oct 11 02:40:24 CEST 2007
139 - port to threaded perls.
140
1414.1 Thu Oct 11 02:38:16 CEST 2007
142 - incompatible change: $SIG{__DIE__} and $SIG{__WARN__} will now
143 be local to each coro (see Coro::State).
144 - incompatible change: for very deep reasons, cede and cede_notself
145 cannot return anything, so nothing will be returned.
146 - possibly bring back 5.10 compatibility (untested).
147 - work around stupid (and wrong) warning on 5.10 :(.
148 - overlay the saved state over the context stack. This saves
149 a few hundred bytes per coroutine on average and also
150 speeds up context switching a bit.
151 - further tune default stack sizes.
152 - (more) correctly calculate stack usage in coro_rss.
153 - Coro::Storable::blocking_* did not properly lock
154 resulting in races between coroutines.
155 - added Coro::Storable::guard.
156 - stopping to trace a coroutine could destroy the cctx of
157 an unrelated coroutine.
158 - explain the relationship between Perl and C coroutines in
159 more detail in Coro::State.
160 - Coro::Util::inet_aton did not short-circuit dotted quad forms,
161 causing a fork per resolve. This also affected Coro::Socket.
162 - switch to a separate stack in $coro->call/eval to avoid
163 invalidating pointers.
164
1654.03 Sat Oct 6 21:24:00 CEST 2007
166 - added Coro::throw method.
167 - minor code cleanups.
168
1694.02 Sat Oct 6 02:36:47 CEST 2007
170 - fix a very minor per-coroutine memleak (a single codereference).
171 - fixed a bug where the currently in-use c context would be freed
172 prematurely (can happen only when programs change the stacksize
173 or use tracing).
174 - tracing can no longer keep a coro alive after it terminated.
175 - do static branch prediction in the common path for gcc. gives
176 about 2-5% speed improvement here.
177
1784.01 Fri Oct 5 22:10:49 CEST 2007
179 - instead of recreating *a* standard output handle we simply
180 use STDOUT, which is faster and hopefully more robust.
181
1824.0 Fri Oct 5 12:56:00 CEST 2007
183 - incompatibly changed Coro::Storable::freeze.
184 - major new feature: added Coro::Debug, for interactive coroutine
185 debugging, tracing and much more.
186 - major bug fix: unbelievable, but true: $_, $/ and many other
187 "saved" variables actually weren't being saved. This has been fixed,
188 of course, while increasing performance while losing all the save
189 flags.
190 - save flags are gone, and all the api functions dealing with them.
191 - added Coro::Semaphore::adjust.
192 - added Coro::Util::fork_eval.
193 - added Coro::Storable::{nfreeze,blocking_{freeze,nfreeze}}.
194 - added Coro::killall.
195 - reduce initial stack sizes to allow for "micro-coroutines".
196 - better async_pool resource management, moved parts of async_pool
197 handling to XS (major speed improvement).
198 - actually croak before modifying important data structures.
199 - refuse to transfer while compiling.
200 - possibly support eval EXPR better now.
201 - enable assembly per default on linux+bsd x86+amd64.
202 - all internal members were renamed _something for easier subclassing.
203 - many minor tweaks.
204
2053.63 Wed May 16 14:10:06 CEST 2007
206 - implement handcoded assembly for x86/amd64 SVR ABI.
207
2083.62 Fri Apr 27 21:36:06 CEST 2007
209 - upgrade libcoro (which might set unwind info correctly).
210 - change default on linux to setjmp/longjmp.
211
2123.61 Thu Apr 19 12:36:18 CEST 2007
213 - Coro::Storable caused an endless loop when thawing invalid
214 pst's sometimes.
215 - use a Semaphore in Coro::Storable, as Storable doesn't
216 seem to be reentrant (although it is documented to
217 be threadsafe...).
218 - fix Coro::Signal to bring back the original unreliable
219 but stateful semantics.
220 - fixed a lot of typos in Coro.pm (patch submitted by David
221 Steinbrunner, which applied flawlessly).
222
2233.6 Sat Apr 14 17:13:31 CEST 2007
224 - added some bugfixes to get eg/myhttpd working again.
225 - added Coro::Storable for often-cede'ing freeze/thaw.
226 - try to do a clean exit when a coroutine calls exit
227 (EXPERIMENTAL).
228 - got rid of indirect call through _coro_init.
229 - updated the partly antique examples in eg/ to
230 work again and be a bit less magic, too.
231 - fixed Coro::Signal semantics to work as documented again.
232
2333.55 Sun Mar 25 01:20:47 CET 2007
234 - add SAVE_DEFFH to save the default filehandle and enable
235 it by default.
236 - finally move socket-operations from Coro::Socket to Coro::Handle
237 to be able to unblock foreign sockets.
238 - add Coro::State::save_also and guarded_save.
239 - add count accessor to Coro::Semaphore.
240 - add Coro::State::cctx_stacksize.
241 - just for the fun of it, do not rely on implicit context,
242 which can dramatically improve performance, but people
243 using windows-process-emulation perls do not care much about
244 performance.
245
2463.51 Sun Mar 4 14:18:04 CET 2007
247 - fixed a problem when you weakened references to Coro::State's
248 (patch by Yuval Kogman).
249
2503.501 Wed Feb 28 12:44:07 CET 2007
251 - rename some global symbols as macosx from hell redefines
252 them without asking.
253
2543.5 Tue Feb 13 20:22:53 CET 2007
255 - do AnyEvent model detection earlier, avoiding problems
256 caused by first using AnyEvent and later Coro::Event.
257 - implement and document Coro::Event event objects.
258 - fix a potential problem in Coro::Event causing crashes.
259 - initialise PL_comppad when creating a new coroutine,
260 avoids crashes on early coro destruction.
261
2623.41 Mon Jan 22 19:19:49 CET 2007
263 - readline on Coro::Handle did not support undefined $/,
264 nor did it deliver partial lines on EOF or error.
265 - implement malloc fallback for stack allocation because
266 stupid broken idiotic OSX has a stupid broken
267 idiotic fits-the-whole-os mmap "implementation" and
268 my dick feels longer if Coro is portable even to
269 obsolete platforms.
270
2713.4 Fri Jan 19 21:52:54 CET 2007
272 - remove t/09_timer.t, as it isn't really testing much
273 but was rather flaky in practise.
274 - async_pool coro would keep arguments and callback alive until
275 it was reused.
276 - cancellation of a coroutine could cause spurious idle calls
277 in cede_notself.
278
2793.3 Sat Jan 6 03:45:00 CET 2007
7 - implement $coro->on_destroy. 280 - implement $coro->on_destroy.
8 - Coro::Event blocking semantics have been changed, 281 - Coro::Event blocking semantics have been changed,
9 documented and - hopefully - improved. 282 documented and - hopefully - improved.
10 - fix nice adding, not subtracting, from priority. 283 - fix nice adding, not subtracting, from priority.
11 - fix ->prio and api_is_ready (patch by Mark Hinds). 284 - fix ->prio and api_is_ready (patch by Mark Hinds).
12 - fixed an assert ("... == prev__cctx->idle_te") 285 - fixed an assert ("... == prev__cctx->idle_te")
13 that could errronously trigger. 286 that could errronously trigger.
287 - fix various large and small memleaks.
14 - use a (hopefully) more stable cancel implementation 288 - use a (hopefully) more stable cancel implementation
15 that immediately frees the coroutine data. 289 that immediately frees the coroutine data.
290 - cede/cede_notself return a status now.
16 - added Coro::guard function. 291 - added Coro::guard function.
292 - added a global coroutine pool for jobs (on my machine,
293 I can create and execute 48k simple coros/s with async,
294 and 128k coros with async_pool).
295 - Coro::AIO now uses the coroutine priority as io priority.
17 296
183.2 Fri Dec 22 05:07:09 CET 2006 2973.2 Fri Dec 22 05:07:09 CET 2006
