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 84.48 Sun Apr 6 20:36:46 CEST 2008
9 - allow coroutine switches during eval's under 5.10.x, as it seems
10 the parser is a per-interpreter option now, so this is safe
11 (this might fix the odd crashing bug).
12 - drop support for 5.9.x versions: they are dead, jim.
13
144.47 Sun Apr 6 00:37:52 CEST 2008
15 - force cctx allocation on API calls: we know we need to force one
16 and gcc actually manages to confuse our heuristic nowadays,
17 leading to crashes and worse.
18 - document force_cctx.
19
204.46 Fri Apr 4 22:05:43 CEST 2008
21 - upgrade libcoro, resulting in pthread-backend (which was only created
22 to fulfill the rules of the programming languages shootout).
23
244.45 Thu Mar 13 11:55:36 CET 2008
25 - fix a file leaking bug in eg/mhyttpd that would allow
26 downloading of any file (reported by oesi).
27 - fix deadlock bug in Coro::Channel (reported by Richard Hundt)
28 (also add testcase).
29 - support Broadcast option in Coro::Socket (patch by Richard Hundt,
30 apparently having loads of fun with that).
31 - implement $state->swap_defsv, ->swap_defav and document ->throw.
32
334.4 Wed Feb 13 16:44:29 CET 2008
34 - only assume .cfi pseudo isns exist on GNU/Linux.
35 - add get_timed method to Coro::Channels.
36 - fixed Coro::Debug manpage.
37 - perl 5.11 compatbility improvement based on patch by
38 Andreas König.
39
404.37 Sun Jan 20 11:25:23 CET 2008
41 - soften the check for an active parser for perl 5.10 (avoiding
42 "Coro::State::transfer called while parsing" in many cases).
43
444.36 Sun Jan 13 10:53:56 CET 2008
45 - reset diehook when terminating from an async_pool as to not
46 trigger any __DIE__ handlers.
47
484.35 Sun Jan 13 04:14:13 CET 2008
49 - "bt" debug command now displays any exceptions
50 from longmess and also skips the innermost
51 stackframes, giving more useufl output.
52 - allow backtraces in coroutines blocked in Coro::EV,
53 at a <1% speed hit.
54 - handle localising of $SIG{__WARN__} and __DIE__
55 properly (with a proper amount of dirty hacking).
56
574.34 Sat Dec 22 17:49:53 CET 2007
58 - upgrade to EV version 2.0 API.
59
604.33 Mon Dec 17 08:36:12 CET 2007
61 - make Coro::AIO etc. loadable in the absence of EV.
62
634.32 Mon Dec 17 07:46:02 CET 2007
64 - majorly improved Coro::Handle's performance with Coro::EV.
65 - implemented the until now mythical Coro::BDB module.
66 - specialcase EV in Coro::AIO and Coro::BDB for extra speed.
67
684.31 Wed Dec 5 12:32:39 CET 2007
69 - remove warn statement form Coro::Util.
70
714.3 Tue Dec 4 20:33:14 CET 2007
72 - calls to the idle function could cause stack corruption
73 when the stack changed.
74 - do no longer rely on the presence of EV::DNS if EV is used
75 (because it is gone), but instead take avdantage of EV::ADNS
76 if available.
77 - add ($) prototypes to all functions in Coro::Storable.
78 - use a conventional (safer) idle callback in Coro::EV.
79 - do accept quickly in Coro::Debug to avoid endless loops.
80
814.22 Fri Nov 30 16:04:04 CET 2007
82 - really use optimised versions for Event and EV in Coro::Util
83 and Coro::Handle.
84
854.21 Sun Nov 25 10:48:59 CET 2007
86 - fix a spurious memory read.
87 - Coro::EV no longer keeps the eventloop "alive".
88
894.2 Fri Nov 9 20:47:05 CET 2007
90 - enable/disable tracing from a new coroutine, not a pooled one.
91 - fix a memleak in Coro::Event.
92 - removed killall call from fork_eval.
93 - made sure store_fd is already loaded so that fork_eval
94 does not have to parse autoload in each subprocess.
95 - only use assembly method if -O switch is in $Config{optimize}.
96 - add (optional) Coro::EV module, so far the best event loop module
97 directly supported by Coro.
98 - if the event model is EV, use EV::DNS to resolve
99 stuff in Coro::Util.
100 - don't get confused by multiple event notifications in Coro::Handle.
101 - initial support for EV (libevent interface).
102 - require Event and EV using configure_requires, to force their existance.
103
1044.13 Wed Oct 24 07:26:45 CEST 2007
105 - add Coro::Storable::blocking_thaw.
106 - use a vastly more complicated technique to localise
107 $SIG{__WARN/DIE__} that also works on perls <= 5.8.8.
108 - use a coroutine for the idle callback Coro::Event,
109 instead of running Event in the current coroutine context.
110 This also catches recursive invocations.
111 - actually report fork errors in gethostbyname and inet_aton.
112
1134.11 Thu Oct 11 02:40:24 CEST 2007
114 - port to threaded perls.
115
1164.1 Thu Oct 11 02:38:16 CEST 2007
117 - incompatible change: $SIG{__DIE__} and $SIG{__WARN__} will now
118 be local to each coro (see Coro::State).
119 - incompatible change: for very deep reasons, cede and cede_notself
120 cannot return anything, so nothing will be returned.
121 - possibly bring back 5.10 compatibility (untested).
122 - work around stupid (and wrong) warning on 5.10 :(.
123 - overlay the saved state over the context stack. This saves
124 a few hundred bytes per coroutine on average and also
125 speeds up context switching a bit.
126 - further tune default stack sizes.
127 - (more) correctly calculate stack usage in coro_rss.
128 - Coro::Storable::blocking_* did not properly lock
129 resulting in races between coroutines.
130 - added Coro::Storable::guard.
131 - stopping to trace a coroutine could destroy the cctx of
132 an unrelated coroutine.
133 - explain the relationship between Perl and C coroutines in
134 more detail in Coro::State.
135 - Coro::Util::inet_aton did not short-circuit dotted quad forms,
136 causing a fork per resolve. This also affected Coro::Socket.
137 - switch to a separate stack in $coro->call/eval to avoid
138 invalidating pointers.
139
1404.03 Sat Oct 6 21:24:00 CEST 2007
141 - added Coro::throw method.
142 - minor code cleanups.
143
1444.02 Sat Oct 6 02:36:47 CEST 2007
145 - fix a very minor per-coroutine memleak (a single codereference).
146 - fixed a bug where the currently in-use c context would be freed
147 prematurely (can happen only when programs change the stacksize
148 or use tracing).
149 - tracing can no longer keep a coro alive after it terminated.
150 - do static branch prediction in the common path for gcc. gives
151 about 2-5% speed improvement here.
152
1534.01 Fri Oct 5 22:10:49 CEST 2007
154 - instead of recreating *a* standard output handle we simply
155 use STDOUT, which is faster and hopefully more robust.
156
1574.0 Fri Oct 5 12:56:00 CEST 2007
158 - incompatibly changed Coro::Storable::freeze.
159 - major new feature: added Coro::Debug, for interactive coroutine
160 debugging, tracing and much more.
161 - major bug fix: unbelievable, but true: $_, $/ and many other
162 "saved" variables actually weren't being saved. This has been fixed,
163 of course, while increasing performance while losing all the save
164 flags.
165 - save flags are gone, and all the api functions dealing with them.
166 - added Coro::Semaphore::adjust.
167 - added Coro::Util::fork_eval.
168 - added Coro::Storable::{nfreeze,blocking_{freeze,nfreeze}}.
169 - added Coro::killall.
170 - reduce initial stack sizes to allow for "micro-coroutines".
171 - better async_pool resource management, moved parts of async_pool
172 handling to XS (major speed improvement).
173 - actually croak before modifying important data structures.
174 - refuse to transfer while compiling.
175 - possibly support eval EXPR better now.
176 - enable assembly per default on linux+bsd x86+amd64.
177 - all internal members were renamed _something for easier subclassing.
178 - many minor tweaks.
179
1803.63 Wed May 16 14:10:06 CEST 2007
181 - implement handcoded assembly for x86/amd64 SVR ABI.
182
1833.62 Fri Apr 27 21:36:06 CEST 2007
184 - upgrade libcoro (which might set unwind info correctly).
185 - change default on linux to setjmp/longjmp.
186
1873.61 Thu Apr 19 12:36:18 CEST 2007
188 - Coro::Storable caused an endless loop when thawing invalid
189 pst's sometimes.
190 - use a Semaphore in Coro::Storable, as Storable doesn't
191 seem to be reentrant (although it is documented to
192 be threadsafe...).
193 - fix Coro::Signal to bring back the original unreliable
194 but stateful semantics.
195 - fixed a lot of typos in Coro.pm (patch submitted by David
196 Steinbrunner, which applied flawlessly).
197
1983.6 Sat Apr 14 17:13:31 CEST 2007
199 - added some bugfixes to get eg/myhttpd working again.
200 - added Coro::Storable for often-cede'ing freeze/thaw.
201 - try to do a clean exit when a coroutine calls exit
202 (EXPERIMENTAL).
203 - got rid of indirect call through _coro_init.
204 - updated the partly antique examples in eg/ to
205 work again and be a bit less magic, too.
206 - fixed Coro::Signal semantics to work as documented again.
207
2083.55 Sun Mar 25 01:20:47 CET 2007
209 - add SAVE_DEFFH to save the default filehandle and enable
210 it by default.
211 - finally move socket-operations from Coro::Socket to Coro::Handle
212 to be able to unblock foreign sockets.
213 - add Coro::State::save_also and guarded_save.
214 - add count accessor to Coro::Semaphore.
215 - add Coro::State::cctx_stacksize.
216 - just for the fun of it, do not rely on implicit context,
217 which can dramatically improve performance, but people
218 using windows-process-emulation perls do not care much about
219 performance.
220
2213.51 Sun Mar 4 14:18:04 CET 2007
222 - fixed a problem when you weakened references to Coro::State's
223 (patch by Yuval Kogman).
224
2253.501 Wed Feb 28 12:44:07 CET 2007
226 - rename some global symbols as macosx from hell redefines
227 them without asking.
228
2293.5 Tue Feb 13 20:22:53 CET 2007
230 - do AnyEvent model detection earlier, avoiding problems
231 caused by first using AnyEvent and later Coro::Event.
232 - implement and document Coro::Event event objects.
233 - fix a potential problem in Coro::Event causing crashes.
234 - initialise PL_comppad when creating a new coroutine,
235 avoids crashes on early coro destruction.
236
2373.41 Mon Jan 22 19:19:49 CET 2007
238 - readline on Coro::Handle did not support undefined $/,
239 nor did it deliver partial lines on EOF or error.
240 - implement malloc fallback for stack allocation because
241 stupid broken idiotic OSX has a stupid broken
242 idiotic fits-the-whole-os mmap "implementation" and
243 my dick feels longer if Coro is portable even to
244 obsolete platforms.
245
2463.4 Fri Jan 19 21:52:54 CET 2007
247 - remove t/09_timer.t, as it isn't really testing much
248 but was rather flaky in practise.
249 - async_pool coro would keep arguments and callback alive until
250 it was reused.
251 - cancellation of a coroutine could cause spurious idle calls
252 in cede_notself.
253
2543.3 Sat Jan 6 03:45:00 CET 2007
7 - implement $coro->on_destroy. 255 - implement $coro->on_destroy.
8 - Coro::Event blocking semantics have been changed, 256 - Coro::Event blocking semantics have been changed,
9 documented and - hopefully - improved. 257 documented and - hopefully - improved.
10 - fix nice adding, not subtracting, from priority. 258 - fix nice adding, not subtracting, from priority.
11 - fix ->prio and api_is_ready (patch by Mark Hinds). 259 - fix ->prio and api_is_ready (patch by Mark Hinds).
12 - fixed an assert ("... == prev__cctx->idle_te") 260 - fixed an assert ("... == prev__cctx->idle_te")
13 that could errronously trigger. 261 that could errronously trigger.
262 - fix various large and small memleaks.
14 - use a (hopefully) more stable cancel implementation 263 - use a (hopefully) more stable cancel implementation
15 that immediately frees the coroutine data. 264 that immediately frees the coroutine data.
265 - cede/cede_notself return a status now.
16 - added Coro::guard function. 266 - added Coro::guard function.
267 - added a global coroutine pool for jobs (on my machine,
268 I can create and execute 48k simple coros/s with async,
269 and 128k coros with async_pool).
270 - Coro::AIO now uses the coroutine priority as io priority.
17 271
183.2 Fri Dec 22 05:07:09 CET 2006 2723.2 Fri Dec 22 05:07:09 CET 2006
