3TODO: destroy gets only called on cancel: fix(?)
4TODO: should explore PerlIO::via::CoroCede and PerlIO::via::CoroAIO.
5TODO: maybe implement a default message channel, very much like Erlang
6 (which is cool in a lot of important aspects (failures!),
7 but very lacking in others (higher level ipc)).

93.8
10 - incompatibly changed Coro::Storable::freeze.
11 - major new feature: added Coro::Debug, for interactive coroutine
12 debugging, tracing and much more.
13 - added Coro::Semaphore::adjust.
14 - added Coro::Util::fork_eval.
15 - added Coro::Storable::{nfreeze,blocking_{freeze,nfreeze}}.
16 - added Coro::killall.
17 - reduce initial stack sizes to allow for "micro-coroutines".
18 - better async_pool resource management, moved parts of async_pool
19 handling to XS (major speed improvement).
20 - actually croak before modifying important data structures.
21 - refuse to transfer while compiling.
22 - possibly support eval EXPR better now.
23 - enable assembly per default on linux+bsd x86+amd64.
24 - all internal members are named _something for easier subclassing.
25 - many minor tweaks.
26
273.63 Wed May 16 14:10:06 CEST 2007
28 - implement handcoded assembly for x86/amd64 SVR ABI.
29
303.62 Fri Apr 27 21:36:06 CEST 2007
31 - upgrade libcoro (which might set unwind info correctly).
32 - change default on linux to setjmp/longjmp.
33
343.61 Thu Apr 19 12:36:18 CEST 2007
35 - Coro::Storable caused an endless loop when thawing invalid
36 pst's sometimes.
37 - use a Semaphore in Coro::Storable, as Storable doesn't
38 seem to be reentrant (although it is documented to
39 be threadsafe...).
40 - fix Coro::Signal to bring back the original unreliable
41 but stateful semantics.
42 - fixed a lot of typos in Coro.pm (patch submitted by David
43 Steinbrunner, which applied flawlessly).
44
453.6 Sat Apr 14 17:13:31 CEST 2007
46 - added some bugfixes to get eg/myhttpd working again.
47 - added Coro::Storable for often-cede'ing freeze/thaw.
48 - try to do a clean exit when a coroutine calls exit
49 (EXPERIMENTAL).
50 - got rid of indirect call through _coro_init.
51 - updated the partly antique examples in eg/ to
52 work again and be a bit less magic, too.
53 - fixed Coro::Signal semantics to work as documented again.
54
553.55 Sun Mar 25 01:20:47 CET 2007
56 - add SAVE_DEFFH to save the default filehandle and enable
57 it by default.
58 - finally move socket-operations from Coro::Socket to Coro::Handle
59 to be able to unblock foreign sockets.
60 - add Coro::State::save_also and guarded_save.
61 - add count accessor to Coro::Semaphore.
62 - add Coro::State::cctx_stacksize.
63 - just for the fun of it, do not rely on implicit context,
64 which can dramatically improve performance, but people
65 using windows-process-emulation perls do not care much about
66 performance.
67
683.51 Sun Mar 4 14:18:04 CET 2007
69 - fixed a problem when you weakened references to Coro::State's
70 (patch by Yuval Kogman).
71
723.501 Wed Feb 28 12:44:07 CET 2007
73 - rename some global symbols as macosx from hell redefines
74 them without asking.
75
763.5 Tue Feb 13 20:22:53 CET 2007
77 - do AnyEvent model detection earlier, avoiding problems
78 caused by first using AnyEvent and later Coro::Event.
79 - implement and document Coro::Event event objects.
80 - fix a potential problem in Coro::Event causing crashes.
81 - initialise PL_comppad when creating a new coroutine,
82 avoids crashes on early coro destruction.
83
843.41 Mon Jan 22 19:19:49 CET 2007
85 - readline on Coro::Handle did not support undefined $/,
86 nor did it deliver partial lines on EOF or error.
87 - implement malloc fallback for stack allocation because
88 stupid broken idiotic OSX has a stupid broken
89 idiotic fits-the-whole-os mmap "implementation" and
90 my dick feels longer if Coro is portable even to
91 obsolete platforms.
92
933.4 Fri Jan 19 21:52:54 CET 2007
94 - remove t/09_timer.t, as it isn't really testing much
95 but was rather flaky in practise.
96 - async_pool coro would keep arguments and callback alive until
97 it was reused.
98 - cancellation of a coroutine could cause spurious idle calls
99 in cede_notself.
100
1013.3 Sat Jan 6 03:45:00 CET 2007
102 - implement $coro->on_destroy.
103 - Coro::Event blocking semantics have been changed,
104 documented and - hopefully - improved.
105 - fix nice adding, not subtracting, from priority.
106 - fix ->prio and api_is_ready (patch by Mark Hinds).
107 - fixed an assert ("... == prev__cctx->idle_te")
108 that could errronously trigger.
109 - fix various large and small memleaks.
110 - use a (hopefully) more stable cancel implementation
111 that immediately frees the coroutine data.
112 - cede/cede_notself return a status now.
113 - added Coro::guard function.
114 - added a global coroutine pool for jobs (on my machine,
115 I can create and execute 48k simple coros/s with async,
116 and 128k coros with async_pool).
117 - Coro::AIO now uses the coroutine priority as io priority.
118
1193.2 Fri Dec 22 05:07:09 CET 2006
120 - improve portability to slightly older perls.
121 - use cleaner coroutine destruction.
122 - simplify configuration for users.
123 - optionally (unrecommended) prefer perl functions over
124 their coro replacements.
125
1263.11 Tue Dec 5 13:11:24 CET 2006
127 - fixed some bogus assert's, but as perl.h disables assert even
128 without NDEBUG (thank you very much), not too many people should
129 notice (that did include myself). Andreas König noticed, though :)
130 - do not save/restore PL_sortcxix on >= 5.9.x, it doesn't seem to have
131 it. Also noticed by Andreas König :)
132 - save/restore tainted status.
133 - verified to pass the testsuite on my 5.9.5.
134
1353.1 Mon Dec 4 23:03:40 CET 2006
136 - INCOMPATIBLE CHANGE: $/ is now per-coroutine (but slow).
137 - incompatible change: transfer flags are now per-state.
138 - give a better error message on deadlock.
139 - document Coro::nready.
140 - enhanced testsuite.
141
1423.01 Sun Dec 3 23:47:42 CET 2006
143 - forgot to include Coro::Timer.
144
1453.0 Sun Dec 3 22:57:25 CET 2006
146 - the "FINALLY COMPLETELY STABLE" release (coming soon:
147 the "FAMOUS LAST WORDS" release).
148 - implement a new stack sharing algorithm, which uses a stack
149 pool (size currently hardcoded).
150 - make stack sharing mandatory (it no longer uses a heuristic).
151 - eval/die no longer cause weird problems under heavy use.
152 - Coro::Event could cause livelocks if it was used but
153 no Coro::Event watchers were used.
154 - Coro::Event now uses asynccheck as prepare does not
155 check for changed watchers.
156 - Coro::Event allows multiple waiting coros and will wake up one
157 per event.
158 - Coro::Event should be cleaner and more efficient now.
159 - new utility function Coro::unblock_sub.
160 - document the sad fact that Event is no longer reentrant.
161 - putting a coroutine into the ready queue twice could under
162 some circumstances lead to stack corruption.
163 - minor incompatibility: subclassing Coro::State is supported
164 directly now without going through a _coro_state member.
165 - state/coro switching is much faster now.
166 - very minor optimisations and code/documentation cleanup.
167 - avoid problems due to compiler inlining.
168 - removed timers from Coro::Timer -> use AnyEvent instead.
169 - replaced Coro::idle coroutine by (cleaner) idle handler.
170 - updated to newest libcoro.
171 - implement enhanced support for valgrind.
172 - implement is_ready and return value for ready.
173 - removed Coro::Cont, it was a misnomer (it's generators),
174 and it was somewhat annoying to get it right. Will come back
175 if somebody asks for it :)
176 - many ->wait methods and Coro::Event could return
177 spuriously without the event having happened.
178
1792.5 Tue Nov 7 12:22:33 CET 2006
180 - made Coro::Util, Coro::Select, Coro::Handle and Coro::Socket
181 use AnyEvent, moved them to Coro/.
182 - added Coro::LWP which contains all the uglyness required to
183 make LWP non-blocking.
184 - should work with perl 5.9.x now (Andreas König made me do it).
185 - fixed another bug in Coro::Select when the timeout was undef.
186 - reuse PL_start_env for all coros, saves some memory per coroutine.
187 - manage PL_top_env differently, hopefully to avoid panic: top_env.
188 - timeout argument was not properly used in Coro::Socket.
189 - allow limited forms of subclassing in Coro::Handle/Coro::Socket.
190 - emulate undocumented(!) functionality of IO::Socket required
191 by LWP(!!).
192 - updated eg/lwp to work with newer lwp's.
193 - remove "FATAL: uncaught exception" prefix. Coroutines that die
194 kill the whole process, just as exceptions in the main "coroutine"
195 did already.
196
1972.1 Wed Nov 1 23:01:13 CET 2006
198 - fix a long-standing bug in Coro::Select where select with
199 zero timeout would instead change the current default filehandle.
200 - use a simpler and hopefully more robust way to clone padlists
201 (uses less memory and a perl function instead of our own).
202 - coro can now create a stack guard area on many architectures.
203 - Coro::AIO properly reexports additional functions from IO::AIO.
204 - updated libcoro with a workaround for OS X,
205 pach and testing by Michael Schwern.
206
2072.0 Tue Oct 24 05:47:17 CEST 2006
208 - support additional aio requests in Coro::AIO.
209
2101.9 (never properly released due to a glitch)
211
2121.8 Thu Feb 2 00:59:06 CET 2006
213 - applied suggested patch by SAMV to avoid problems during stupid
214 mark & sweep gc run.
215 - applied patch by Scott Walters for 5.9.3 compatibility.
216
2171.7 Tue Dec 27 01:41:58 CET 2005
218 - added Coro::AIO, a thin wrapper around IO::AIO.
219 - improved Makefile.PL explanations.
220
2211.6 Mon Dec 12 21:30:05 CET 2005
222 - additionally save PM_curpm might fix as-of-yet
223 unseen problems with regex matches being attributed to the
224 wrong package.
225 - add t/10_bugs.t, which currently checks against imho broken
226 perls that use 0.26MB of stack space per Perl_magic_get
227 invocation (newer linuxes) as opposed to the 0.0002MB perl
228 normally uses.
229 - make stacksize configurable for the ultimate debian experience.
230
2311.51 Mon Dec 12 18:48:36 CET 2005
232 - remove debugging warn() accidentally left in Coro::Select.
233
2341.5 Tue Nov 29 13:32:44 CET 2005
235 - use Coro::Event inside Coro::Select to avoid spurious deadlocks.
236 - fix Coro::Select 'select'.
237 - strict'ify some modules.
238 - libcoro errornously restored the SIGUSR2 handler to SIGUSR1.
239 - use XSLoader in selected modules.
240 - remove some 5.6 compatibility cruft.
241
2421.4 Tue Sep 6 00:11:05 CEST 2005
243 - libcoro did not take into account the trampoline on amd64,
244 when 'l'inux method was used.
245
2461.31 Tue Aug 30 23:31:33 CEST 2005
247 - some portability fixes/workarounds.
