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
5 (which is cool in a lot of important aspects (failures!),
6 but very lacking in others (higher level ipc)).

63.3 84.36 Sun Jan 13 10:53:56 CET 2008
9 - reset diehook when terminating from an async_pool as to not
10 trigger any __DIE__ handlers.
11
124.35 Sun Jan 13 04:14:13 CET 2008
13 - "bt" debug command now displays any exceptions
14 from longmess and also skips the innermost
15 stackframes, giving more useufl output.
16 - allow backtraces in coroutines blocked in Coro::EV,
17 at a <1% speed hit.
18 - handle localising of $SIG{__WARN__} and __DIE__
19 properly (with a proper amount of dirty hacking).
20
214.34 Sat Dec 22 17:49:53 CET 2007
22 - upgrade to EV version 2.0 API.
23
244.33 Mon Dec 17 08:36:12 CET 2007
25 - make Coro::AIO etc. loadable in the absence of EV.
26
274.32 Mon Dec 17 07:46:02 CET 2007
28 - majorly improved Coro::Handle's performance with Coro::EV.
29 - implemented the until now mythical Coro::BDB module.
30 - specialcase EV in Coro::AIO and Coro::BDB for extra speed.
31
324.31 Wed Dec 5 12:32:39 CET 2007
33 - remove warn statement form Coro::Util.
34
354.3 Tue Dec 4 20:33:14 CET 2007
36 - calls to the idle function could cause stack corruption
37 when the stack changed.
38 - do no longer rely on the presence of EV::DNS if EV is used
39 (because it is gone), but instead take avdantage of EV::ADNS
40 if available.
41 - add ($) prototypes to all functions in Coro::Storable.
42 - use a conventional (safer) idle callback in Coro::EV.
43 - do accept quickly in Coro::Debug to avoid endless loops.
44
454.22 Fri Nov 30 16:04:04 CET 2007
46 - really use optimised versions for Event and EV in Coro::Util
47 and Coro::Handle.
48
494.21 Sun Nov 25 10:48:59 CET 2007
50 - fix a spurious memory read.
51 - Coro::EV no longer keeps the eventloop "alive".
52
534.2 Fri Nov 9 20:47:05 CET 2007
54 - enable/disable tracing from a new coroutine, not a pooled one.
55 - fix a memleak in Coro::Event.
56 - removed killall call from fork_eval.
57 - made sure store_fd is already loaded so that fork_eval
58 does not have to parse autoload in each subprocess.
59 - only use assembly method if -O switch is in $Config{optimize}.
60 - add (optional) Coro::EV module, so far the best event loop module
61 directly supported by Coro.
62 - if the event model is EV, use EV::DNS to resolve
63 stuff in Coro::Util.
64 - don't get confused by multiple event notifications in Coro::Handle.
65 - initial support for EV (libevent interface).
66 - require Event and EV using configure_requires, to force their existance.
67
684.13 Wed Oct 24 07:26:45 CEST 2007
69 - add Coro::Storable::blocking_thaw.
70 - use a vastly more complicated technique to localise
71 $SIG{__WARN/DIE__} that also works on perls <= 5.8.8.
72 - use a coroutine for the idle callback Coro::Event,
73 instead of running Event in the current coroutine context.
74 This also catches recursive invocations.
75 - actually report fork errors in gethostbyname and inet_aton.
76
774.11 Thu Oct 11 02:40:24 CEST 2007
78 - port to threaded perls.
79
804.1 Thu Oct 11 02:38:16 CEST 2007
81 - incompatible change: $SIG{__DIE__} and $SIG{__WARN__} will now
82 be local to each coro (see Coro::State).
83 - incompatible change: for very deep reasons, cede and cede_notself
84 cannot return anything, so nothing will be returned.
85 - possibly bring back 5.10 compatibility (untested).
86 - work around stupid (and wrong) warning on 5.10 :(.
87 - overlay the saved state over the context stack. This saves
88 a few hundred bytes per coroutine on average and also
89 speeds up context switching a bit.
90 - further tune default stack sizes.
91 - (more) correctly calculate stack usage in coro_rss.
92 - Coro::Storable::blocking_* did not properly lock
93 resulting in races between coroutines.
94 - added Coro::Storable::guard.
95 - stopping to trace a coroutine could destroy the cctx of
96 an unrelated coroutine.
97 - explain the relationship between Perl and C coroutines in
98 more detail in Coro::State.
99 - Coro::Util::inet_aton did not short-circuit dotted quad forms,
100 causing a fork per resolve. This also affected Coro::Socket.
101 - switch to a separate stack in $coro->call/eval to avoid
102 invalidating pointers.
103
1044.03 Sat Oct 6 21:24:00 CEST 2007
105 - added Coro::throw method.
106 - minor code cleanups.
107
1084.02 Sat Oct 6 02:36:47 CEST 2007
109 - fix a very minor per-coroutine memleak (a single codereference).
110 - fixed a bug where the currently in-use c context would be freed
111 prematurely (can happen only when programs change the stacksize
112 or use tracing).
113 - tracing can no longer keep a coro alive after it terminated.
114 - do static branch prediction in the common path for gcc. gives
115 about 2-5% speed improvement here.
116
1174.01 Fri Oct 5 22:10:49 CEST 2007
118 - instead of recreating *a* standard output handle we simply
119 use STDOUT, which is faster and hopefully more robust.
120
1214.0 Fri Oct 5 12:56:00 CEST 2007
122 - incompatibly changed Coro::Storable::freeze.
123 - major new feature: added Coro::Debug, for interactive coroutine
124 debugging, tracing and much more.
125 - major bug fix: unbelievable, but true: $_, $/ and many other
126 "saved" variables actually weren't being saved. This has been fixed,
127 of course, while increasing performance while losing all the save
128 flags.
129 - save flags are gone, and all the api functions dealing with them.
130 - added Coro::Semaphore::adjust.
131 - added Coro::Util::fork_eval.
132 - added Coro::Storable::{nfreeze,blocking_{freeze,nfreeze}}.
133 - added Coro::killall.
134 - reduce initial stack sizes to allow for "micro-coroutines".
135 - better async_pool resource management, moved parts of async_pool
136 handling to XS (major speed improvement).
137 - actually croak before modifying important data structures.
138 - refuse to transfer while compiling.
139 - possibly support eval EXPR better now.
140 - enable assembly per default on linux+bsd x86+amd64.
141 - all internal members were renamed _something for easier subclassing.
142 - many minor tweaks.
143
1443.63 Wed May 16 14:10:06 CEST 2007
145 - implement handcoded assembly for x86/amd64 SVR ABI.
146
1473.62 Fri Apr 27 21:36:06 CEST 2007
148 - upgrade libcoro (which might set unwind info correctly).
149 - change default on linux to setjmp/longjmp.
150
1513.61 Thu Apr 19 12:36:18 CEST 2007
152 - Coro::Storable caused an endless loop when thawing invalid
153 pst's sometimes.
154 - use a Semaphore in Coro::Storable, as Storable doesn't
155 seem to be reentrant (although it is documented to
156 be threadsafe...).
157 - fix Coro::Signal to bring back the original unreliable
158 but stateful semantics.
159 - fixed a lot of typos in Coro.pm (patch submitted by David
160 Steinbrunner, which applied flawlessly).
161
1623.6 Sat Apr 14 17:13:31 CEST 2007
163 - added some bugfixes to get eg/myhttpd working again.
164 - added Coro::Storable for often-cede'ing freeze/thaw.
165 - try to do a clean exit when a coroutine calls exit
166 (EXPERIMENTAL).
167 - got rid of indirect call through _coro_init.
168 - updated the partly antique examples in eg/ to
169 work again and be a bit less magic, too.
170 - fixed Coro::Signal semantics to work as documented again.
171
1723.55 Sun Mar 25 01:20:47 CET 2007
173 - add SAVE_DEFFH to save the default filehandle and enable
174 it by default.
175 - finally move socket-operations from Coro::Socket to Coro::Handle
176 to be able to unblock foreign sockets.
177 - add Coro::State::save_also and guarded_save.
178 - add count accessor to Coro::Semaphore.
179 - add Coro::State::cctx_stacksize.
180 - just for the fun of it, do not rely on implicit context,
181 which can dramatically improve performance, but people
182 using windows-process-emulation perls do not care much about
183 performance.
184
1853.51 Sun Mar 4 14:18:04 CET 2007
186 - fixed a problem when you weakened references to Coro::State's
187 (patch by Yuval Kogman).
188
1893.501 Wed Feb 28 12:44:07 CET 2007
190 - rename some global symbols as macosx from hell redefines
191 them without asking.
192
1933.5 Tue Feb 13 20:22:53 CET 2007
194 - do AnyEvent model detection earlier, avoiding problems
195 caused by first using AnyEvent and later Coro::Event.
196 - implement and document Coro::Event event objects.
197 - fix a potential problem in Coro::Event causing crashes.
198 - initialise PL_comppad when creating a new coroutine,
199 avoids crashes on early coro destruction.
200
2013.41 Mon Jan 22 19:19:49 CET 2007
202 - readline on Coro::Handle did not support undefined $/,
203 nor did it deliver partial lines on EOF or error.
204 - implement malloc fallback for stack allocation because
205 stupid broken idiotic OSX has a stupid broken
206 idiotic fits-the-whole-os mmap "implementation" and
207 my dick feels longer if Coro is portable even to
208 obsolete platforms.
209
2103.4 Fri Jan 19 21:52:54 CET 2007
211 - remove t/09_timer.t, as it isn't really testing much
212 but was rather flaky in practise.
213 - async_pool coro would keep arguments and callback alive until
214 it was reused.
215 - cancellation of a coroutine could cause spurious idle calls
216 in cede_notself.
217
2183.3 Sat Jan 6 03:45:00 CET 2007
7 - implement $coro->on_destroy. 219 - implement $coro->on_destroy.

9 documented and - hopefully - improved. 221 documented and - hopefully - improved.
10 - fix nice adding, not subtracting, from priority. 222 - fix nice adding, not subtracting, from priority.
11 - fix ->prio and api_is_ready (patch by Mark Hinds). 223 - fix ->prio and api_is_ready (patch by Mark Hinds).
12 - fixed an assert ("... == prev__cctx->idle_te") 224 - fixed an assert ("... == prev__cctx->idle_te")
13 that could errronously trigger. 225 that could errronously trigger.
226 - fix various large and small memleaks.
14 - use a (hopefully) more stable cancel implementation 227 - use a (hopefully) more stable cancel implementation
15 that immediately frees the coroutine data. 228 that immediately frees the coroutine data.
229 - cede/cede_notself return a status now.
16 - added Coro::guard function. 230 - added Coro::guard function.
231 - added a global coroutine pool for jobs (on my machine,
232 I can create and execute 48k simple coros/s with async,
233 and 128k coros with async_pool).
234 - Coro::AIO now uses the coroutine priority as io priority.
17 235
183.2 Fri Dec 22 05:07:09 CET 2006 2363.2 Fri Dec 22 05:07:09 CET 2006
