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)).

63.3 84.50 Thu Apr 10 09:43:17 CEST 2008
9 - I did it twice! (see 4.49).
10
114.49 Sun Apr 6 21:23:31 CEST 2008
12 - grr, instead of compiling the recent changes on 5.10 only they
13 were compiled on 5.8 only.
14
154.48 Sun Apr 6 20:36:46 CEST 2008
16 - allow coroutine switches during eval's under 5.10.x, as it seems
17 the parser is a per-interpreter option now, so this is safe
18 (this might fix the odd crashing bug).
19 - drop support for 5.9.x versions: they are dead, jim.
20
214.47 Sun Apr 6 00:37:52 CEST 2008
22 - force cctx allocation on API calls: we know we need to force one
23 and gcc actually manages to confuse our heuristic nowadays,
24 leading to crashes and worse.
25 - document force_cctx.
26
274.46 Fri Apr 4 22:05:43 CEST 2008
28 - upgrade libcoro, resulting in pthread-backend (which was only created
29 to fulfill the rules of the programming languages shootout).
30
314.45 Thu Mar 13 11:55:36 CET 2008
32 - fix a file leaking bug in eg/mhyttpd that would allow
33 downloading of any file (reported by oesi).
34 - fix deadlock bug in Coro::Channel (reported by Richard Hundt)
35 (also add testcase).
36 - support Broadcast option in Coro::Socket (patch by Richard Hundt,
37 apparently having loads of fun with that).
38 - implement $state->swap_defsv, ->swap_defav and document ->throw.
39
404.4 Wed Feb 13 16:44:29 CET 2008
41 - only assume .cfi pseudo isns exist on GNU/Linux.
42 - add get_timed method to Coro::Channels.
43 - fixed Coro::Debug manpage.
44 - perl 5.11 compatbility improvement based on patch by
45 Andreas König.
46
474.37 Sun Jan 20 11:25:23 CET 2008
48 - soften the check for an active parser for perl 5.10 (avoiding
49 "Coro::State::transfer called while parsing" in many cases).
50
514.36 Sun Jan 13 10:53:56 CET 2008
52 - reset diehook when terminating from an async_pool as to not
53 trigger any __DIE__ handlers.
54
554.35 Sun Jan 13 04:14:13 CET 2008
56 - "bt" debug command now displays any exceptions
57 from longmess and also skips the innermost
58 stackframes, giving more useufl output.
59 - allow backtraces in coroutines blocked in Coro::EV,
60 at a <1% speed hit.
61 - handle localising of $SIG{__WARN__} and __DIE__
62 properly (with a proper amount of dirty hacking).
63
644.34 Sat Dec 22 17:49:53 CET 2007
65 - upgrade to EV version 2.0 API.
66
674.33 Mon Dec 17 08:36:12 CET 2007
68 - make Coro::AIO etc. loadable in the absence of EV.
69
704.32 Mon Dec 17 07:46:02 CET 2007
71 - majorly improved Coro::Handle's performance with Coro::EV.
72 - implemented the until now mythical Coro::BDB module.
73 - specialcase EV in Coro::AIO and Coro::BDB for extra speed.
74
754.31 Wed Dec 5 12:32:39 CET 2007
76 - remove warn statement form Coro::Util.
77
784.3 Tue Dec 4 20:33:14 CET 2007
79 - calls to the idle function could cause stack corruption
80 when the stack changed.
81 - do no longer rely on the presence of EV::DNS if EV is used
82 (because it is gone), but instead take avdantage of EV::ADNS
83 if available.
84 - add ($) prototypes to all functions in Coro::Storable.
85 - use a conventional (safer) idle callback in Coro::EV.
86 - do accept quickly in Coro::Debug to avoid endless loops.
87
884.22 Fri Nov 30 16:04:04 CET 2007
89 - really use optimised versions for Event and EV in Coro::Util
90 and Coro::Handle.
91
924.21 Sun Nov 25 10:48:59 CET 2007
93 - fix a spurious memory read.
94 - Coro::EV no longer keeps the eventloop "alive".
95
964.2 Fri Nov 9 20:47:05 CET 2007
97 - enable/disable tracing from a new coroutine, not a pooled one.
98 - fix a memleak in Coro::Event.
99 - removed killall call from fork_eval.
100 - made sure store_fd is already loaded so that fork_eval
101 does not have to parse autoload in each subprocess.
102 - only use assembly method if -O switch is in $Config{optimize}.
103 - add (optional) Coro::EV module, so far the best event loop module
104 directly supported by Coro.
105 - if the event model is EV, use EV::DNS to resolve
106 stuff in Coro::Util.
107 - don't get confused by multiple event notifications in Coro::Handle.
108 - initial support for EV (libevent interface).
109 - require Event and EV using configure_requires, to force their existance.
110
1114.13 Wed Oct 24 07:26:45 CEST 2007
112 - add Coro::Storable::blocking_thaw.
113 - use a vastly more complicated technique to localise
114 $SIG{__WARN/DIE__} that also works on perls <= 5.8.8.
115 - use a coroutine for the idle callback Coro::Event,
116 instead of running Event in the current coroutine context.
117 This also catches recursive invocations.
118 - actually report fork errors in gethostbyname and inet_aton.
119
1204.11 Thu Oct 11 02:40:24 CEST 2007
121 - port to threaded perls.
122
1234.1 Thu Oct 11 02:38:16 CEST 2007
124 - incompatible change: $SIG{__DIE__} and $SIG{__WARN__} will now
125 be local to each coro (see Coro::State).
126 - incompatible change: for very deep reasons, cede and cede_notself
127 cannot return anything, so nothing will be returned.
128 - possibly bring back 5.10 compatibility (untested).
129 - work around stupid (and wrong) warning on 5.10 :(.
130 - overlay the saved state over the context stack. This saves
131 a few hundred bytes per coroutine on average and also
132 speeds up context switching a bit.
133 - further tune default stack sizes.
134 - (more) correctly calculate stack usage in coro_rss.
135 - Coro::Storable::blocking_* did not properly lock
136 resulting in races between coroutines.
137 - added Coro::Storable::guard.
138 - stopping to trace a coroutine could destroy the cctx of
139 an unrelated coroutine.
140 - explain the relationship between Perl and C coroutines in
141 more detail in Coro::State.
142 - Coro::Util::inet_aton did not short-circuit dotted quad forms,
143 causing a fork per resolve. This also affected Coro::Socket.
144 - switch to a separate stack in $coro->call/eval to avoid
145 invalidating pointers.
146
1474.03 Sat Oct 6 21:24:00 CEST 2007
148 - added Coro::throw method.
149 - minor code cleanups.
150
1514.02 Sat Oct 6 02:36:47 CEST 2007
152 - fix a very minor per-coroutine memleak (a single codereference).
153 - fixed a bug where the currently in-use c context would be freed
154 prematurely (can happen only when programs change the stacksize
155 or use tracing).
156 - tracing can no longer keep a coro alive after it terminated.
157 - do static branch prediction in the common path for gcc. gives
158 about 2-5% speed improvement here.
159
1604.01 Fri Oct 5 22:10:49 CEST 2007
161 - instead of recreating *a* standard output handle we simply
162 use STDOUT, which is faster and hopefully more robust.
163
1644.0 Fri Oct 5 12:56:00 CEST 2007
165 - incompatibly changed Coro::Storable::freeze.
166 - major new feature: added Coro::Debug, for interactive coroutine
167 debugging, tracing and much more.
168 - major bug fix: unbelievable, but true: $_, $/ and many other
169 "saved" variables actually weren't being saved. This has been fixed,
170 of course, while increasing performance while losing all the save
171 flags.
172 - save flags are gone, and all the api functions dealing with them.
173 - added Coro::Semaphore::adjust.
174 - added Coro::Util::fork_eval.
175 - added Coro::Storable::{nfreeze,blocking_{freeze,nfreeze}}.
176 - added Coro::killall.
177 - reduce initial stack sizes to allow for "micro-coroutines".
178 - better async_pool resource management, moved parts of async_pool
179 handling to XS (major speed improvement).
180 - actually croak before modifying important data structures.
181 - refuse to transfer while compiling.
182 - possibly support eval EXPR better now.
183 - enable assembly per default on linux+bsd x86+amd64.
184 - all internal members were renamed _something for easier subclassing.
185 - many minor tweaks.
186
1873.63 Wed May 16 14:10:06 CEST 2007
188 - implement handcoded assembly for x86/amd64 SVR ABI.
189
1903.62 Fri Apr 27 21:36:06 CEST 2007
191 - upgrade libcoro (which might set unwind info correctly).
192 - change default on linux to setjmp/longjmp.
193
1943.61 Thu Apr 19 12:36:18 CEST 2007
195 - Coro::Storable caused an endless loop when thawing invalid
196 pst's sometimes.
197 - use a Semaphore in Coro::Storable, as Storable doesn't
198 seem to be reentrant (although it is documented to
199 be threadsafe...).
200 - fix Coro::Signal to bring back the original unreliable
201 but stateful semantics.
202 - fixed a lot of typos in Coro.pm (patch submitted by David
203 Steinbrunner, which applied flawlessly).
204
2053.6 Sat Apr 14 17:13:31 CEST 2007
206 - added some bugfixes to get eg/myhttpd working again.
207 - added Coro::Storable for often-cede'ing freeze/thaw.
208 - try to do a clean exit when a coroutine calls exit
209 (EXPERIMENTAL).
210 - got rid of indirect call through _coro_init.
211 - updated the partly antique examples in eg/ to
212 work again and be a bit less magic, too.
213 - fixed Coro::Signal semantics to work as documented again.
214
2153.55 Sun Mar 25 01:20:47 CET 2007
216 - add SAVE_DEFFH to save the default filehandle and enable
217 it by default.
218 - finally move socket-operations from Coro::Socket to Coro::Handle
219 to be able to unblock foreign sockets.
220 - add Coro::State::save_also and guarded_save.
221 - add count accessor to Coro::Semaphore.
222 - add Coro::State::cctx_stacksize.
223 - just for the fun of it, do not rely on implicit context,
224 which can dramatically improve performance, but people
225 using windows-process-emulation perls do not care much about
226 performance.
227
2283.51 Sun Mar 4 14:18:04 CET 2007
229 - fixed a problem when you weakened references to Coro::State's
230 (patch by Yuval Kogman).
231
2323.501 Wed Feb 28 12:44:07 CET 2007
233 - rename some global symbols as macosx from hell redefines
234 them without asking.
235
2363.5 Tue Feb 13 20:22:53 CET 2007
237 - do AnyEvent model detection earlier, avoiding problems
238 caused by first using AnyEvent and later Coro::Event.
239 - implement and document Coro::Event event objects.
240 - fix a potential problem in Coro::Event causing crashes.
241 - initialise PL_comppad when creating a new coroutine,
242 avoids crashes on early coro destruction.
243
2443.41 Mon Jan 22 19:19:49 CET 2007
245 - readline on Coro::Handle did not support undefined $/,
246 nor did it deliver partial lines on EOF or error.
247 - implement malloc fallback for stack allocation because
248 stupid broken idiotic OSX has a stupid broken
249 idiotic fits-the-whole-os mmap "implementation" and
250 my dick feels longer if Coro is portable even to
251 obsolete platforms.
252
2533.4 Fri Jan 19 21:52:54 CET 2007
254 - remove t/09_timer.t, as it isn't really testing much
255 but was rather flaky in practise.
256 - async_pool coro would keep arguments and callback alive until
257 it was reused.
258 - cancellation of a coroutine could cause spurious idle calls
259 in cede_notself.
260
2613.3 Sat Jan 6 03:45:00 CET 2007
7 - implement $coro->on_destroy. 262 - implement $coro->on_destroy.
8 - Coro::Event blocking semantics have been changed, 263 - Coro::Event blocking semantics have been changed,
9 documented and - hopefully - improved. 264 documented and - hopefully - improved.
10 - fix nice adding, not subtracting, from priority. 265 - fix nice adding, not subtracting, from priority.
11 - fix ->prio and api_is_ready (patch by Mark Hinds). 266 - fix ->prio and api_is_ready (patch by Mark Hinds).
12 - fixed an assert ("... == prev__cctx->idle_te") 267 - fixed an assert ("... == prev__cctx->idle_te")
13 that could errronously trigger. 268 that could errronously trigger.
269 - fix various large and small memleaks.
14 - use a (hopefully) more stable cancel implementation 270 - use a (hopefully) more stable cancel implementation
15 that immediately frees the coroutine data. 271 that immediately frees the coroutine data.
272 - cede/cede_notself return a status now.
16 - added Coro::guard function. 273 - added Coro::guard function.
274 - added a global coroutine pool for jobs (on my machine,
275 I can create and execute 48k simple coros/s with async,
276 and 128k coros with async_pool).
277 - Coro::AIO now uses the coroutine priority as io priority.
17 278
183.2 Fri Dec 22 05:07:09 CET 2006 2793.2 Fri Dec 22 05:07:09 CET 2006
