2 2
3TODO: better (earlier) error messages on broken transfer's
4TODO: destroy gets only called on cancel: fix(?)
5TODO: should explore PerlIO::via::CoroCede and PerlIO::via::CoroAIO.
6TODO: maybe implement a default message channel, very much like Erlang
7 (which is cool in a lot of important aspects (failures!),
8 but very lacking in others).

103.7
11 - added Coro::Debug, interactive coroutine debugging.
12 - added Coro::Semaphore::adjust.
13 - added Coro::Util::fork_eval.
14 - incompatibly changed Coro::Storable::freeze.
15 - added Coro::Storable::{nfreeze,blocking_{freeze,nfreeze}}.
16 - reduce initial stack sizes to allow for "micro-coroutines".
17
183.63 Wed May 16 14:10:06 CEST 2007
19 - implement handcoded assembly for x86/amd64 SVR ABI.
20
213.62 Fri Apr 27 21:36:06 CEST 2007
22 - upgrade libcoro (which might set unwind info correctly).
23 - change default on linux to setjmp/longjmp.
24
253.61 Thu Apr 19 12:36:18 CEST 2007
26 - Coro::Storable caused an endless loop when thawing invalid
27 pst's sometimes.
28 - use a Semaphore in Coro::Storable, as Storable doesn't
29 seem to be reentrant (although it is documented to
30 be threadsafe...).
31 - fix Coro::Signal to bring back the original unreliable
32 but stateful semantics.
33 - fixed a lot of typos in Coro.pm (patch submitted by David
34 Steinbrunner, which applied flawlessly).
35
363.6 Sat Apr 14 17:13:31 CEST 2007
37 - added some bugfixes to get eg/myhttpd working again.
38 - added Coro::Storable for often-cede'ing freeze/thaw.
39 - try to do a clean exit when a coroutine calls exit
40 (EXPERIMENTAL).
41 - got rid of indirect call through _coro_init.
42 - updated the partly antique examples in eg/ to
43 work again and be a bit less magic, too.
44 - fixed Coro::Signal semantics to work as documented again.
45
463.55 Sun Mar 25 01:20:47 CET 2007
47 - add SAVE_DEFFH to save the default filehandle and enable
48 it by default.
49 - finally move socket-operations from Coro::Socket to Coro::Handle
50 to be able to unblock foreign sockets.
51 - add Coro::State::save_also and guarded_save.
52 - add count accessor to Coro::Semaphore.
53 - add Coro::State::cctx_stacksize.
54 - just for the fun of it, do not rely on implicit context,
55 which can dramatically improve performance, but people
56 using windows-process-emulation perls do not care much about
57 performance.
58
593.51 Sun Mar 4 14:18:04 CET 2007
60 - fixed a problem when you weakened references to Coro::State's
61 (patch by Yuval Kogman).
62
633.501 Wed Feb 28 12:44:07 CET 2007
64 - rename some global symbols as macosx from hell redefines
65 them without asking.
66
673.5 Tue Feb 13 20:22:53 CET 2007
68 - do AnyEvent model detection earlier, avoiding problems
69 caused by first using AnyEvent and later Coro::Event.
70 - implement and document Coro::Event event objects.
71 - fix a potential problem in Coro::Event causing crashes.
72 - initialise PL_comppad when creating a new coroutine,
73 avoids crashes on early coro destruction.
74
753.41 Mon Jan 22 19:19:49 CET 2007
76 - readline on Coro::Handle did not support undefined $/,
77 nor did it deliver partial lines on EOF or error.
78 - implement malloc fallback for stack allocation because
79 stupid broken idiotic OSX has a stupid broken
80 idiotic fits-the-whole-os mmap "implementation" and
81 my dick feels longer if Coro is portable even to
82 obsolete platforms.
83
843.4 Fri Jan 19 21:52:54 CET 2007
85 - remove t/09_timer.t, as it isn't really testing much
86 but was rather flaky in practise.
87 - async_pool coro would keep arguments and callback alive until
88 it was reused.
89 - cancellation of a coroutine could cause spurious idle calls
90 in cede_notself.
91
923.3 Sat Jan 6 03:45:00 CET 2007
93 - implement $coro->on_destroy.
94 - Coro::Event blocking semantics have been changed,
95 documented and - hopefully - improved.
96 - fix nice adding, not subtracting, from priority.
97 - fix ->prio and api_is_ready (patch by Mark Hinds).
98 - fixed an assert ("... == prev__cctx->idle_te")
99 that could errronously trigger.
100 - fix various large and small memleaks.
101 - use a (hopefully) more stable cancel implementation
102 that immediately frees the coroutine data.
103 - cede/cede_notself return a status now.
104 - added Coro::guard function.
105 - added a global coroutine pool for jobs (on my machine,
106 I can create and execute 48k simple coros/s with async,
107 and 128k coros with async_pool).
108 - Coro::AIO now uses the coroutine priority as io priority.
109
1103.2 Fri Dec 22 05:07:09 CET 2006
111 - improve portability to slightly older perls.
112 - use cleaner coroutine destruction.
113 - simplify configuration for users.
114 - optionally (unrecommended) prefer perl functions over
115 their coro replacements.
116
1173.11 Tue Dec 5 13:11:24 CET 2006
118 - fixed some bogus assert's, but as perl.h disables assert even
119 without NDEBUG (thank you very much), not too many people should
120 notice (that did include myself). Andreas König noticed, though :)
121 - do not save/restore PL_sortcxix on >= 5.9.x, it doesn't seem to have
122 it. Also noticed by Andreas König :)
123 - save/restore tainted status.
124 - verified to pass the testsuite on my 5.9.5.
125
1263.1 Mon Dec 4 23:03:40 CET 2006
127 - INCOMPATIBLE CHANGE: $/ is now per-coroutine (but slow).
128 - incompatible change: transfer flags are now per-state.
129 - give a better error message on deadlock.
130 - document Coro::nready.
131 - enhanced testsuite.
132
1333.01 Sun Dec 3 23:47:42 CET 2006
134 - forgot to include Coro::Timer.
135
1363.0 Sun Dec 3 22:57:25 CET 2006
137 - the "FINALLY COMPLETELY STABLE" release (coming soon:
138 the "FAMOUS LAST WORDS" release).
139 - implement a new stack sharing algorithm, which uses a stack
140 pool (size currently hardcoded).
141 - make stack sharing mandatory (it no longer uses a heuristic).
142 - eval/die no longer cause weird problems under heavy use.
143 - Coro::Event could cause livelocks if it was used but
144 no Coro::Event watchers were used.
145 - Coro::Event now uses asynccheck as prepare does not
146 check for changed watchers.
147 - Coro::Event allows multiple waiting coros and will wake up one
148 per event.
149 - Coro::Event should be cleaner and more efficient now.
150 - new utility function Coro::unblock_sub.
151 - document the sad fact that Event is no longer reentrant.
152 - putting a coroutine into the ready queue twice could under
153 some circumstances lead to stack corruption.
154 - minor incompatibility: subclassing Coro::State is supported
155 directly now without going through a _coro_state member.
156 - state/coro switching is much faster now.
157 - very minor optimisations and code/documentation cleanup.
158 - avoid problems due to compiler inlining.
159 - removed timers from Coro::Timer -> use AnyEvent instead.
160 - replaced Coro::idle coroutine by (cleaner) idle handler.
161 - updated to newest libcoro.
162 - implement enhanced support for valgrind.
163 - implement is_ready and return value for ready.
164 - removed Coro::Cont, it was a misnomer (it's generators),
165 and it was somewhat annoying to get it right. Will come back
166 if somebody asks for it :)
167 - many ->wait methods and Coro::Event could return
168 spuriously without the event having happened.
169
1702.5 Tue Nov 7 12:22:33 CET 2006
171 - made Coro::Util, Coro::Select, Coro::Handle and Coro::Socket
172 use AnyEvent, moved them to Coro/.
173 - added Coro::LWP which contains all the uglyness required to
174 make LWP non-blocking.
175 - should work with perl 5.9.x now (Andreas König made me do it).
176 - fixed another bug in Coro::Select when the timeout was undef.
177 - reuse PL_start_env for all coros, saves some memory per coroutine.
178 - manage PL_top_env differently, hopefully to avoid panic: top_env.
179 - timeout argument was not properly used in Coro::Socket.
180 - allow limited forms of subclassing in Coro::Handle/Coro::Socket.
181 - emulate undocumented(!) functionality of IO::Socket required
182 by LWP(!!).
183 - updated eg/lwp to work with newer lwp's.
184 - remove "FATAL: uncaught exception" prefix. Coroutines that die
185 kill the whole process, just as exceptions in the main "coroutine"
186 did already.
187
1882.1 Wed Nov 1 23:01:13 CET 2006
189 - fix a long-standing bug in Coro::Select where select with
190 zero timeout would instead change the current default filehandle.
191 - use a simpler and hopefully more robust way to clone padlists
192 (uses less memory and a perl function instead of our own).
193 - coro can now create a stack guard area on many architectures.
194 - Coro::AIO properly reexports additional functions from IO::AIO.
195 - updated libcoro with a workaround for OS X,
196 pach and testing by Michael Schwern.
197
1982.0 Tue Oct 24 05:47:17 CEST 2006
199 - support additional aio requests in Coro::AIO.
200
2011.9 (never properly released due to a glitch)
202
2031.8 Thu Feb 2 00:59:06 CET 2006
204 - applied suggested patch by SAMV to avoid problems during stupid
205 mark & sweep gc run.
206 - applied patch by Scott Walters for 5.9.3 compatibility.
207
2081.7 Tue Dec 27 01:41:58 CET 2005
209 - added Coro::AIO, a thin wrapper around IO::AIO.
210 - improved Makefile.PL explanations.
211
2121.6 Mon Dec 12 21:30:05 CET 2005
213 - additionally save PM_curpm might fix as-of-yet
214 unseen problems with regex matches being attributed to the
215 wrong package.
216 - add t/10_bugs.t, which currently checks against imho broken
217 perls that use 0.26MB of stack space per Perl_magic_get
218 invocation (newer linuxes) as opposed to the 0.0002MB perl
219 normally uses.
220 - make stacksize configurable for the ultimate debian experience.
221
2221.51 Mon Dec 12 18:48:36 CET 2005
223 - remove debugging warn() accidentally left in Coro::Select.

2251.5 Tue Nov 29 13:32:44 CET 2005
226 - use Coro::Event inside Coro::Select to avoid spurious deadlocks.
227 - fix Coro::Select 'select'.
228 - strict'ify some modules.
229 - libcoro errornously restored the SIGUSR2 handler to SIGUSR1.
230 - use XSLoader in selected modules.
231 - remove some 5.6 compatibility cruft.
232
2331.4 Tue Sep 6 00:11:05 CEST 2005
234 - libcoro did not take into account the trampoline on amd64,
235 when 'l'inux method was used.
236

242 - improve Coro::State docs, remove reference to nonexisting
243 Coro::State::flush method.
244 - no longer autodetect windows, present it as an option instead.
245
2461.2 Mon May 16 02:00:55 CEST 2005
3 - included libcoro.c earlier in State.xs, might improve portability. 247 - included libcoro.c earlier in State.xs, might improve portability.
4 - use a faster and possibly more stable Coro::Cont implementation. 248 - use a faster and possibly more stable Coro::Cont implementation.
249 - accept x86_64 in addition to amd64 for optimized linux-amd64 support.
250 - fix bugs Coro::SemaphoreSet that could cause locks never to be freed.
