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 84.49 Sun Apr 6 21:23:31 CEST 2008
9 - grr, instead of compiling the recent changes on 5.10 only they
10 were compiled on 5.8 only.
11
124.48 Sun Apr 6 20:36:46 CEST 2008
13 - allow coroutine switches during eval's under 5.10.x, as it seems
14 the parser is a per-interpreter option now, so this is safe
15 (this might fix the odd crashing bug).
16 - drop support for 5.9.x versions: they are dead, jim.
17
184.47 Sun Apr 6 00:37:52 CEST 2008
19 - force cctx allocation on API calls: we know we need to force one
20 and gcc actually manages to confuse our heuristic nowadays,
21 leading to crashes and worse.
22 - document force_cctx.
23
244.46 Fri Apr 4 22:05:43 CEST 2008
25 - upgrade libcoro, resulting in pthread-backend (which was only created
26 to fulfill the rules of the programming languages shootout).
27
284.45 Thu Mar 13 11:55:36 CET 2008
29 - fix a file leaking bug in eg/mhyttpd that would allow
30 downloading of any file (reported by oesi).
31 - fix deadlock bug in Coro::Channel (reported by Richard Hundt)
32 (also add testcase).
33 - support Broadcast option in Coro::Socket (patch by Richard Hundt,
34 apparently having loads of fun with that).
35 - implement $state->swap_defsv, ->swap_defav and document ->throw.
36
374.4 Wed Feb 13 16:44:29 CET 2008
38 - only assume .cfi pseudo isns exist on GNU/Linux.
39 - add get_timed method to Coro::Channels.
40 - fixed Coro::Debug manpage.
41 - perl 5.11 compatbility improvement based on patch by
42 Andreas König.
43
444.37 Sun Jan 20 11:25:23 CET 2008
45 - soften the check for an active parser for perl 5.10 (avoiding
46 "Coro::State::transfer called while parsing" in many cases).
47
484.36 Sun Jan 13 10:53:56 CET 2008
49 - reset diehook when terminating from an async_pool as to not
50 trigger any __DIE__ handlers.
51
524.35 Sun Jan 13 04:14:13 CET 2008
53 - "bt" debug command now displays any exceptions
54 from longmess and also skips the innermost
55 stackframes, giving more useufl output.
56 - allow backtraces in coroutines blocked in Coro::EV,
57 at a <1% speed hit.
58 - handle localising of $SIG{__WARN__} and __DIE__
59 properly (with a proper amount of dirty hacking).
60
614.34 Sat Dec 22 17:49:53 CET 2007
62 - upgrade to EV version 2.0 API.
63
644.33 Mon Dec 17 08:36:12 CET 2007
65 - make Coro::AIO etc. loadable in the absence of EV.
66
674.32 Mon Dec 17 07:46:02 CET 2007
68 - majorly improved Coro::Handle's performance with Coro::EV.
69 - implemented the until now mythical Coro::BDB module.
70 - specialcase EV in Coro::AIO and Coro::BDB for extra speed.
71
724.31 Wed Dec 5 12:32:39 CET 2007
73 - remove warn statement form Coro::Util.
74
754.3 Tue Dec 4 20:33:14 CET 2007
76 - calls to the idle function could cause stack corruption
77 when the stack changed.
78 - do no longer rely on the presence of EV::DNS if EV is used
79 (because it is gone), but instead take avdantage of EV::ADNS
80 if available.
81 - add ($) prototypes to all functions in Coro::Storable.
82 - use a conventional (safer) idle callback in Coro::EV.
83 - do accept quickly in Coro::Debug to avoid endless loops.
84
854.22 Fri Nov 30 16:04:04 CET 2007
86 - really use optimised versions for Event and EV in Coro::Util
87 and Coro::Handle.
88
894.21 Sun Nov 25 10:48:59 CET 2007
90 - fix a spurious memory read.
91 - Coro::EV no longer keeps the eventloop "alive".
92
934.2 Fri Nov 9 20:47:05 CET 2007
94 - enable/disable tracing from a new coroutine, not a pooled one.
95 - fix a memleak in Coro::Event.
96 - removed killall call from fork_eval.
97 - made sure store_fd is already loaded so that fork_eval
98 does not have to parse autoload in each subprocess.
99 - only use assembly method if -O switch is in $Config{optimize}.
100 - add (optional) Coro::EV module, so far the best event loop module
101 directly supported by Coro.
102 - if the event model is EV, use EV::DNS to resolve
103 stuff in Coro::Util.
104 - don't get confused by multiple event notifications in Coro::Handle.
105 - initial support for EV (libevent interface).
106 - require Event and EV using configure_requires, to force their existance.
107
1084.13 Wed Oct 24 07:26:45 CEST 2007
109 - add Coro::Storable::blocking_thaw.
110 - use a vastly more complicated technique to localise
111 $SIG{__WARN/DIE__} that also works on perls <= 5.8.8.
112 - use a coroutine for the idle callback Coro::Event,
113 instead of running Event in the current coroutine context.
114 This also catches recursive invocations.
115 - actually report fork errors in gethostbyname and inet_aton.
116
1174.11 Thu Oct 11 02:40:24 CEST 2007
118 - port to threaded perls.
119
1204.1 Thu Oct 11 02:38:16 CEST 2007
121 - incompatible change: $SIG{__DIE__} and $SIG{__WARN__} will now
122 be local to each coro (see Coro::State).
123 - incompatible change: for very deep reasons, cede and cede_notself
124 cannot return anything, so nothing will be returned.
125 - possibly bring back 5.10 compatibility (untested).
126 - work around stupid (and wrong) warning on 5.10 :(.
127 - overlay the saved state over the context stack. This saves
128 a few hundred bytes per coroutine on average and also
129 speeds up context switching a bit.
130 - further tune default stack sizes.
131 - (more) correctly calculate stack usage in coro_rss.
132 - Coro::Storable::blocking_* did not properly lock
133 resulting in races between coroutines.
134 - added Coro::Storable::guard.
135 - stopping to trace a coroutine could destroy the cctx of
136 an unrelated coroutine.
137 - explain the relationship between Perl and C coroutines in
138 more detail in Coro::State.
139 - Coro::Util::inet_aton did not short-circuit dotted quad forms,
140 causing a fork per resolve. This also affected Coro::Socket.
141 - switch to a separate stack in $coro->call/eval to avoid
142 invalidating pointers.
143
1444.03 Sat Oct 6 21:24:00 CEST 2007
145 - added Coro::throw method.
146 - minor code cleanups.
147
1484.02 Sat Oct 6 02:36:47 CEST 2007
149 - fix a very minor per-coroutine memleak (a single codereference).
150 - fixed a bug where the currently in-use c context would be freed
151 prematurely (can happen only when programs change the stacksize
152 or use tracing).
153 - tracing can no longer keep a coro alive after it terminated.
154 - do static branch prediction in the common path for gcc. gives
155 about 2-5% speed improvement here.
156
1574.01 Fri Oct 5 22:10:49 CEST 2007
158 - instead of recreating *a* standard output handle we simply
159 use STDOUT, which is faster and hopefully more robust.
160
1614.0 Fri Oct 5 12:56:00 CEST 2007
162 - incompatibly changed Coro::Storable::freeze.
163 - major new feature: added Coro::Debug, for interactive coroutine
164 debugging, tracing and much more.
165 - major bug fix: unbelievable, but true: $_, $/ and many other
166 "saved" variables actually weren't being saved. This has been fixed,
167 of course, while increasing performance while losing all the save
168 flags.
169 - save flags are gone, and all the api functions dealing with them.
170 - added Coro::Semaphore::adjust.
171 - added Coro::Util::fork_eval.
172 - added Coro::Storable::{nfreeze,blocking_{freeze,nfreeze}}.
173 - added Coro::killall.
174 - reduce initial stack sizes to allow for "micro-coroutines".
175 - better async_pool resource management, moved parts of async_pool
176 handling to XS (major speed improvement).
177 - actually croak before modifying important data structures.
178 - refuse to transfer while compiling.
179 - possibly support eval EXPR better now.
180 - enable assembly per default on linux+bsd x86+amd64.
181 - all internal members were renamed _something for easier subclassing.
182 - many minor tweaks.
183
1843.63 Wed May 16 14:10:06 CEST 2007
185 - implement handcoded assembly for x86/amd64 SVR ABI.
186
1873.62 Fri Apr 27 21:36:06 CEST 2007
188 - upgrade libcoro (which might set unwind info correctly).
189 - change default on linux to setjmp/longjmp.
190
1913.61 Thu Apr 19 12:36:18 CEST 2007
192 - Coro::Storable caused an endless loop when thawing invalid
193 pst's sometimes.
194 - use a Semaphore in Coro::Storable, as Storable doesn't
195 seem to be reentrant (although it is documented to
196 be threadsafe...).
197 - fix Coro::Signal to bring back the original unreliable
198 but stateful semantics.
199 - fixed a lot of typos in Coro.pm (patch submitted by David
200 Steinbrunner, which applied flawlessly).
201
2023.6 Sat Apr 14 17:13:31 CEST 2007
203 - added some bugfixes to get eg/myhttpd working again.
204 - added Coro::Storable for often-cede'ing freeze/thaw.
205 - try to do a clean exit when a coroutine calls exit
206 (EXPERIMENTAL).
207 - got rid of indirect call through _coro_init.
208 - updated the partly antique examples in eg/ to
209 work again and be a bit less magic, too.
210 - fixed Coro::Signal semantics to work as documented again.
211
2123.55 Sun Mar 25 01:20:47 CET 2007
213 - add SAVE_DEFFH to save the default filehandle and enable
214 it by default.
215 - finally move socket-operations from Coro::Socket to Coro::Handle
216 to be able to unblock foreign sockets.
217 - add Coro::State::save_also and guarded_save.
218 - add count accessor to Coro::Semaphore.
219 - add Coro::State::cctx_stacksize.
220 - just for the fun of it, do not rely on implicit context,
221 which can dramatically improve performance, but people
222 using windows-process-emulation perls do not care much about
223 performance.
224
2253.51 Sun Mar 4 14:18:04 CET 2007
226 - fixed a problem when you weakened references to Coro::State's
227 (patch by Yuval Kogman).
228
2293.501 Wed Feb 28 12:44:07 CET 2007
230 - rename some global symbols as macosx from hell redefines
231 them without asking.
232
2333.5 Tue Feb 13 20:22:53 CET 2007
234 - do AnyEvent model detection earlier, avoiding problems
235 caused by first using AnyEvent and later Coro::Event.
236 - implement and document Coro::Event event objects.
237 - fix a potential problem in Coro::Event causing crashes.
238 - initialise PL_comppad when creating a new coroutine,
239 avoids crashes on early coro destruction.
240
2413.41 Mon Jan 22 19:19:49 CET 2007
242 - readline on Coro::Handle did not support undefined $/,
243 nor did it deliver partial lines on EOF or error.
244 - implement malloc fallback for stack allocation because
245 stupid broken idiotic OSX has a stupid broken
246 idiotic fits-the-whole-os mmap "implementation" and
247 my dick feels longer if Coro is portable even to
248 obsolete platforms.
249
2503.4 Fri Jan 19 21:52:54 CET 2007
251 - remove t/09_timer.t, as it isn't really testing much
252 but was rather flaky in practise.
253 - async_pool coro would keep arguments and callback alive until
254 it was reused.
255 - cancellation of a coroutine could cause spurious idle calls
256 in cede_notself.
257
2583.3 Sat Jan 6 03:45:00 CET 2007
7 - implement $coro->on_destroy. 259 - implement $coro->on_destroy.
8 - Coro::Event blocking semantics have been changed, 260 - Coro::Event blocking semantics have been changed,
9 documented and - hopefully - improved. 261 documented and - hopefully - improved.
10 - fix nice adding, not subtracting, from priority. 262 - fix nice adding, not subtracting, from priority.
11 - fix ->prio and api_is_ready (patch by Mark Hinds). 263 - fix ->prio and api_is_ready (patch by Mark Hinds).
… …
17 - cede/cede_notself return a status now. 269 - cede/cede_notself return a status now.
18 - added Coro::guard function. 270 - added Coro::guard function.
19 - added a global coroutine pool for jobs (on my machine, 271 - added a global coroutine pool for jobs (on my machine,
20 I can create and execute 48k simple coros/s with async, 272 I can create and execute 48k simple coros/s with async,
21 and 128k coros with async_pool). 273 and 128k coros with async_pool).
274 - Coro::AIO now uses the coroutine priority as io priority.
22 275
233.2 Fri Dec 22 05:07:09 CET 2006 2763.2 Fri Dec 22 05:07:09 CET 2006
