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 - INCOMPATIBLE CHANGE: sub/code attributes are no longer supported
9 by the Coro module. It was a mistake.
10 - (experimental) support for activestate perl 5.10.
11 - coro_sigelem_set did not return a value although it had to,
12 actual impact unknown.
13
144.51 Mon Apr 14 13:28:27 CEST 2008
15 - make it compile again on 5.8.
16
174.50 Thu Apr 10 09:43:17 CEST 2008
18 - I did it twice! (see 4.49).
19
204.49 Sun Apr 6 21:23:31 CEST 2008
21 - grr, instead of compiling the recent changes on 5.10 only they
22 were compiled on 5.8 only.
23
244.48 Sun Apr 6 20:36:46 CEST 2008
25 - allow coroutine switches during eval's under 5.10.x, as it seems
26 the parser is a per-interpreter option now, so this is safe
27 (this might fix the odd crashing bug).
28 - drop support for 5.9.x versions: they are dead, jim.
29
304.47 Sun Apr 6 00:37:52 CEST 2008
31 - force cctx allocation on API calls: we know we need to force one
32 and gcc actually manages to confuse our heuristic nowadays,
33 leading to crashes and worse.
34 - document force_cctx.
35
364.46 Fri Apr 4 22:05:43 CEST 2008
37 - upgrade libcoro, resulting in pthread-backend (which was only created
38 to fulfill the rules of the programming languages shootout).
39
404.45 Thu Mar 13 11:55:36 CET 2008
41 - fix a file leaking bug in eg/mhyttpd that would allow
42 downloading of any file (reported by oesi).
43 - fix deadlock bug in Coro::Channel (reported by Richard Hundt)
44 (also add testcase).
45 - support Broadcast option in Coro::Socket (patch by Richard Hundt,
46 apparently having loads of fun with that).
47 - implement $state->swap_defsv, ->swap_defav and document ->throw.
48
494.4 Wed Feb 13 16:44:29 CET 2008
50 - only assume .cfi pseudo isns exist on GNU/Linux.
51 - add get_timed method to Coro::Channels.
52 - fixed Coro::Debug manpage.
53 - perl 5.11 compatbility improvement based on patch by
54 Andreas König.
55
564.37 Sun Jan 20 11:25:23 CET 2008
57 - soften the check for an active parser for perl 5.10 (avoiding
58 "Coro::State::transfer called while parsing" in many cases).
59
604.36 Sun Jan 13 10:53:56 CET 2008
61 - reset diehook when terminating from an async_pool as to not
62 trigger any __DIE__ handlers.
63
644.35 Sun Jan 13 04:14:13 CET 2008
65 - "bt" debug command now displays any exceptions
66 from longmess and also skips the innermost
67 stackframes, giving more useufl output.
68 - allow backtraces in coroutines blocked in Coro::EV,
69 at a <1% speed hit.
70 - handle localising of $SIG{__WARN__} and __DIE__
71 properly (with a proper amount of dirty hacking).
72
734.34 Sat Dec 22 17:49:53 CET 2007
74 - upgrade to EV version 2.0 API.
75
764.33 Mon Dec 17 08:36:12 CET 2007
77 - make Coro::AIO etc. loadable in the absence of EV.
78
794.32 Mon Dec 17 07:46:02 CET 2007
80 - majorly improved Coro::Handle's performance with Coro::EV.
81 - implemented the until now mythical Coro::BDB module.
82 - specialcase EV in Coro::AIO and Coro::BDB for extra speed.
83
844.31 Wed Dec 5 12:32:39 CET 2007
85 - remove warn statement form Coro::Util.
86
874.3 Tue Dec 4 20:33:14 CET 2007
88 - calls to the idle function could cause stack corruption
89 when the stack changed.
90 - do no longer rely on the presence of EV::DNS if EV is used
91 (because it is gone), but instead take avdantage of EV::ADNS
92 if available.
93 - add ($) prototypes to all functions in Coro::Storable.
94 - use a conventional (safer) idle callback in Coro::EV.
95 - do accept quickly in Coro::Debug to avoid endless loops.
96
974.22 Fri Nov 30 16:04:04 CET 2007
98 - really use optimised versions for Event and EV in Coro::Util
99 and Coro::Handle.
100
1014.21 Sun Nov 25 10:48:59 CET 2007
102 - fix a spurious memory read.
103 - Coro::EV no longer keeps the eventloop "alive".
104
1054.2 Fri Nov 9 20:47:05 CET 2007
106 - enable/disable tracing from a new coroutine, not a pooled one.
107 - fix a memleak in Coro::Event.
108 - removed killall call from fork_eval.
109 - made sure store_fd is already loaded so that fork_eval
110 does not have to parse autoload in each subprocess.
111 - only use assembly method if -O switch is in $Config{optimize}.
112 - add (optional) Coro::EV module, so far the best event loop module
113 directly supported by Coro.
114 - if the event model is EV, use EV::DNS to resolve
115 stuff in Coro::Util.
116 - don't get confused by multiple event notifications in Coro::Handle.
117 - initial support for EV (libevent interface).
118 - require Event and EV using configure_requires, to force their existance.
119
1204.13 Wed Oct 24 07:26:45 CEST 2007
121 - add Coro::Storable::blocking_thaw.
122 - use a vastly more complicated technique to localise
123 $SIG{__WARN/DIE__} that also works on perls <= 5.8.8.
124 - use a coroutine for the idle callback Coro::Event,
125 instead of running Event in the current coroutine context.
126 This also catches recursive invocations.
127 - actually report fork errors in gethostbyname and inet_aton.
128
1294.11 Thu Oct 11 02:40:24 CEST 2007
130 - port to threaded perls.
131
1324.1 Thu Oct 11 02:38:16 CEST 2007
133 - incompatible change: $SIG{__DIE__} and $SIG{__WARN__} will now
134 be local to each coro (see Coro::State).
135 - incompatible change: for very deep reasons, cede and cede_notself
136 cannot return anything, so nothing will be returned.
137 - possibly bring back 5.10 compatibility (untested).
138 - work around stupid (and wrong) warning on 5.10 :(.
139 - overlay the saved state over the context stack. This saves
140 a few hundred bytes per coroutine on average and also
141 speeds up context switching a bit.
142 - further tune default stack sizes.
143 - (more) correctly calculate stack usage in coro_rss.
144 - Coro::Storable::blocking_* did not properly lock
145 resulting in races between coroutines.
146 - added Coro::Storable::guard.
147 - stopping to trace a coroutine could destroy the cctx of
148 an unrelated coroutine.
149 - explain the relationship between Perl and C coroutines in
150 more detail in Coro::State.
151 - Coro::Util::inet_aton did not short-circuit dotted quad forms,
152 causing a fork per resolve. This also affected Coro::Socket.
153 - switch to a separate stack in $coro->call/eval to avoid
154 invalidating pointers.
155
1564.03 Sat Oct 6 21:24:00 CEST 2007
157 - added Coro::throw method.
158 - minor code cleanups.
159
1604.02 Sat Oct 6 02:36:47 CEST 2007
161 - fix a very minor per-coroutine memleak (a single codereference).
162 - fixed a bug where the currently in-use c context would be freed
163 prematurely (can happen only when programs change the stacksize
164 or use tracing).
165 - tracing can no longer keep a coro alive after it terminated.
166 - do static branch prediction in the common path for gcc. gives
167 about 2-5% speed improvement here.
168
1694.01 Fri Oct 5 22:10:49 CEST 2007
170 - instead of recreating *a* standard output handle we simply
171 use STDOUT, which is faster and hopefully more robust.
172
1734.0 Fri Oct 5 12:56:00 CEST 2007
174 - incompatibly changed Coro::Storable::freeze.
175 - major new feature: added Coro::Debug, for interactive coroutine
176 debugging, tracing and much more.
177 - major bug fix: unbelievable, but true: $_, $/ and many other
178 "saved" variables actually weren't being saved. This has been fixed,
179 of course, while increasing performance while losing all the save
180 flags.
181 - save flags are gone, and all the api functions dealing with them.
182 - added Coro::Semaphore::adjust.
183 - added Coro::Util::fork_eval.
184 - added Coro::Storable::{nfreeze,blocking_{freeze,nfreeze}}.
185 - added Coro::killall.
186 - reduce initial stack sizes to allow for "micro-coroutines".
187 - better async_pool resource management, moved parts of async_pool
188 handling to XS (major speed improvement).
189 - actually croak before modifying important data structures.
190 - refuse to transfer while compiling.
191 - possibly support eval EXPR better now.
192 - enable assembly per default on linux+bsd x86+amd64.
193 - all internal members were renamed _something for easier subclassing.
194 - many minor tweaks.
195
1963.63 Wed May 16 14:10:06 CEST 2007
197 - implement handcoded assembly for x86/amd64 SVR ABI.
198
1993.62 Fri Apr 27 21:36:06 CEST 2007
200 - upgrade libcoro (which might set unwind info correctly).
201 - change default on linux to setjmp/longjmp.
202
2033.61 Thu Apr 19 12:36:18 CEST 2007
204 - Coro::Storable caused an endless loop when thawing invalid
205 pst's sometimes.
206 - use a Semaphore in Coro::Storable, as Storable doesn't
207 seem to be reentrant (although it is documented to
208 be threadsafe...).
209 - fix Coro::Signal to bring back the original unreliable
210 but stateful semantics.
211 - fixed a lot of typos in Coro.pm (patch submitted by David
212 Steinbrunner, which applied flawlessly).
213
2143.6 Sat Apr 14 17:13:31 CEST 2007
215 - added some bugfixes to get eg/myhttpd working again.
216 - added Coro::Storable for often-cede'ing freeze/thaw.
217 - try to do a clean exit when a coroutine calls exit
218 (EXPERIMENTAL).
219 - got rid of indirect call through _coro_init.
220 - updated the partly antique examples in eg/ to
221 work again and be a bit less magic, too.
222 - fixed Coro::Signal semantics to work as documented again.
223
2243.55 Sun Mar 25 01:20:47 CET 2007
225 - add SAVE_DEFFH to save the default filehandle and enable
226 it by default.
227 - finally move socket-operations from Coro::Socket to Coro::Handle
228 to be able to unblock foreign sockets.
229 - add Coro::State::save_also and guarded_save.
230 - add count accessor to Coro::Semaphore.
231 - add Coro::State::cctx_stacksize.
232 - just for the fun of it, do not rely on implicit context,
233 which can dramatically improve performance, but people
234 using windows-process-emulation perls do not care much about
235 performance.
236
2373.51 Sun Mar 4 14:18:04 CET 2007
238 - fixed a problem when you weakened references to Coro::State's
239 (patch by Yuval Kogman).
240
2413.501 Wed Feb 28 12:44:07 CET 2007
242 - rename some global symbols as macosx from hell redefines
243 them without asking.
244
2453.5 Tue Feb 13 20:22:53 CET 2007
246 - do AnyEvent model detection earlier, avoiding problems
247 caused by first using AnyEvent and later Coro::Event.
248 - implement and document Coro::Event event objects.
249 - fix a potential problem in Coro::Event causing crashes.
250 - initialise PL_comppad when creating a new coroutine,
251 avoids crashes on early coro destruction.
252
2533.41 Mon Jan 22 19:19:49 CET 2007
254 - readline on Coro::Handle did not support undefined $/,
255 nor did it deliver partial lines on EOF or error.
256 - implement malloc fallback for stack allocation because
257 stupid broken idiotic OSX has a stupid broken
258 idiotic fits-the-whole-os mmap "implementation" and
259 my dick feels longer if Coro is portable even to
260 obsolete platforms.
261
2623.4 Fri Jan 19 21:52:54 CET 2007
263 - remove t/09_timer.t, as it isn't really testing much
264 but was rather flaky in practise.
265 - async_pool coro would keep arguments and callback alive until
266 it was reused.
267 - cancellation of a coroutine could cause spurious idle calls
268 in cede_notself.
269
2703.3 Sat Jan 6 03:45:00 CET 2007
7 - implement $coro->on_destroy. 271 - implement $coro->on_destroy.
8 - Coro::Event blocking semantics have been changed, 272 - Coro::Event blocking semantics have been changed,
9 documented and - hopefully - improved. 273 documented and - hopefully - improved.
10 - fix nice adding, not subtracting, from priority. 274 - fix nice adding, not subtracting, from priority.
11 - fix ->prio and api_is_ready (patch by Mark Hinds). 275 - fix ->prio and api_is_ready (patch by Mark Hinds).
12 - fixed an assert ("... == prev__cctx->idle_te") 276 - fixed an assert ("... == prev__cctx->idle_te")
13 that could errronously trigger. 277 that could errronously trigger.
278 - fix various large and small memleaks.
14 - use a (hopefully) more stable cancel implementation 279 - use a (hopefully) more stable cancel implementation
15 that immediately frees the coroutine data. 280 that immediately frees the coroutine data.
281 - cede/cede_notself return a status now.
16 - added Coro::guard function. 282 - added Coro::guard function.
283 - added a global coroutine pool for jobs (on my machine,
284 I can create and execute 48k simple coros/s with async,
285 and 128k coros with async_pool).
286 - Coro::AIO now uses the coroutine priority as io priority.
17 287
183.2 Fri Dec 22 05:07:09 CET 2006 2883.2 Fri Dec 22 05:07:09 CET 2006
