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).
9
103.7
11 - incompatibly changed Coro::Storable::freeze.
12 - added Coro::Debug, interactive coroutine debugging.
13 - added Coro::Semaphore::adjust.
14 - added Coro::Util::fork_eval.
15 - added Coro::Storable::{nfreeze,blocking_{freeze,nfreeze}}.
16 - reduce initial stack sizes to allow for "micro-coroutines".
17 - many minor tweaks.
18
193.63 Wed May 16 14:10:06 CEST 2007
20 - implement handcoded assembly for x86/amd64 SVR ABI.
21
223.62 Fri Apr 27 21:36:06 CEST 2007
23 - upgrade libcoro (which might set unwind info correctly).
24 - change default on linux to setjmp/longjmp.
25
263.61 Thu Apr 19 12:36:18 CEST 2007
27 - Coro::Storable caused an endless loop when thawing invalid
28 pst's sometimes.
29 - use a Semaphore in Coro::Storable, as Storable doesn't
30 seem to be reentrant (although it is documented to
31 be threadsafe...).
32 - fix Coro::Signal to bring back the original unreliable
33 but stateful semantics.
34 - fixed a lot of typos in Coro.pm (patch submitted by David
35 Steinbrunner, which applied flawlessly).
36
373.6 Sat Apr 14 17:13:31 CEST 2007
38 - added some bugfixes to get eg/myhttpd working again.
39 - added Coro::Storable for often-cede'ing freeze/thaw.
40 - try to do a clean exit when a coroutine calls exit
41 (EXPERIMENTAL).
42 - got rid of indirect call through _coro_init.
43 - updated the partly antique examples in eg/ to
44 work again and be a bit less magic, too.
45 - fixed Coro::Signal semantics to work as documented again.
46
473.55 Sun Mar 25 01:20:47 CET 2007
48 - add SAVE_DEFFH to save the default filehandle and enable
49 it by default.
50 - finally move socket-operations from Coro::Socket to Coro::Handle
51 to be able to unblock foreign sockets.
52 - add Coro::State::save_also and guarded_save.
53 - add count accessor to Coro::Semaphore.
54 - add Coro::State::cctx_stacksize.
55 - just for the fun of it, do not rely on implicit context,
56 which can dramatically improve performance, but people
57 using windows-process-emulation perls do not care much about
58 performance.
59
603.51 Sun Mar 4 14:18:04 CET 2007
61 - fixed a problem when you weakened references to Coro::State's
62 (patch by Yuval Kogman).
63
643.501 Wed Feb 28 12:44:07 CET 2007
65 - rename some global symbols as macosx from hell redefines
66 them without asking.
67
683.5 Tue Feb 13 20:22:53 CET 2007
69 - do AnyEvent model detection earlier, avoiding problems
70 caused by first using AnyEvent and later Coro::Event.
71 - implement and document Coro::Event event objects.
72 - fix a potential problem in Coro::Event causing crashes.
73 - initialise PL_comppad when creating a new coroutine,
74 avoids crashes on early coro destruction.
75
763.41 Mon Jan 22 19:19:49 CET 2007
77 - readline on Coro::Handle did not support undefined $/,
78 nor did it deliver partial lines on EOF or error.
79 - implement malloc fallback for stack allocation because
80 stupid broken idiotic OSX has a stupid broken
81 idiotic fits-the-whole-os mmap "implementation" and
82 my dick feels longer if Coro is portable even to
83 obsolete platforms.
84
853.4 Fri Jan 19 21:52:54 CET 2007
86 - remove t/09_timer.t, as it isn't really testing much
87 but was rather flaky in practise.
88 - async_pool coro would keep arguments and callback alive until
89 it was reused.
90 - cancellation of a coroutine could cause spurious idle calls
91 in cede_notself.
92
933.3 Sat Jan 6 03:45:00 CET 2007
94 - implement $coro->on_destroy.
95 - Coro::Event blocking semantics have been changed,
96 documented and - hopefully - improved.
97 - fix nice adding, not subtracting, from priority.
98 - fix ->prio and api_is_ready (patch by Mark Hinds).
99 - fixed an assert ("... == prev__cctx->idle_te")
100 that could errronously trigger.
101 - fix various large and small memleaks.
102 - use a (hopefully) more stable cancel implementation
103 that immediately frees the coroutine data.
104 - cede/cede_notself return a status now.
105 - added Coro::guard function.
106 - added a global coroutine pool for jobs (on my machine,
107 I can create and execute 48k simple coros/s with async,
108 and 128k coros with async_pool).
109 - Coro::AIO now uses the coroutine priority as io priority.
110
1113.2 Fri Dec 22 05:07:09 CET 2006
112 - improve portability to slightly older perls.
113 - use cleaner coroutine destruction.
114 - simplify configuration for users.
115 - optionally (unrecommended) prefer perl functions over
116 their coro replacements.
117
1183.11 Tue Dec 5 13:11:24 CET 2006
119 - fixed some bogus assert's, but as perl.h disables assert even
120 without NDEBUG (thank you very much), not too many people should
121 notice (that did include myself). Andreas König noticed, though :)
122 - do not save/restore PL_sortcxix on >= 5.9.x, it doesn't seem to have
123 it. Also noticed by Andreas König :)
124 - save/restore tainted status.
125 - verified to pass the testsuite on my 5.9.5.
126
1273.1 Mon Dec 4 23:03:40 CET 2006
128 - INCOMPATIBLE CHANGE: $/ is now per-coroutine (but slow).
129 - incompatible change: transfer flags are now per-state.
130 - give a better error message on deadlock.
131 - document Coro::nready.
132 - enhanced testsuite.
133
1343.01 Sun Dec 3 23:47:42 CET 2006
135 - forgot to include Coro::Timer.
136
1373.0 Sun Dec 3 22:57:25 CET 2006
138 - the "FINALLY COMPLETELY STABLE" release (coming soon:
139 the "FAMOUS LAST WORDS" release).
140 - implement a new stack sharing algorithm, which uses a stack
141 pool (size currently hardcoded).
142 - make stack sharing mandatory (it no longer uses a heuristic).
143 - eval/die no longer cause weird problems under heavy use.
144 - Coro::Event could cause livelocks if it was used but
145 no Coro::Event watchers were used.
146 - Coro::Event now uses asynccheck as prepare does not
147 check for changed watchers.
148 - Coro::Event allows multiple waiting coros and will wake up one
149 per event.
150 - Coro::Event should be cleaner and more efficient now.
151 - new utility function Coro::unblock_sub.
152 - document the sad fact that Event is no longer reentrant.
153 - putting a coroutine into the ready queue twice could under
154 some circumstances lead to stack corruption.
155 - minor incompatibility: subclassing Coro::State is supported
156 directly now without going through a _coro_state member.
157 - state/coro switching is much faster now.
158 - very minor optimisations and code/documentation cleanup.
159 - avoid problems due to compiler inlining.
160 - removed timers from Coro::Timer -> use AnyEvent instead.
161 - replaced Coro::idle coroutine by (cleaner) idle handler.
162 - updated to newest libcoro.
163 - implement enhanced support for valgrind.
164 - implement is_ready and return value for ready.
165 - removed Coro::Cont, it was a misnomer (it's generators),
166 and it was somewhat annoying to get it right. Will come back
167 if somebody asks for it :)
168 - many ->wait methods and Coro::Event could return
169 spuriously without the event having happened.
170
1712.5 Tue Nov 7 12:22:33 CET 2006
172 - made Coro::Util, Coro::Select, Coro::Handle and Coro::Socket
173 use AnyEvent, moved them to Coro/.
174 - added Coro::LWP which contains all the uglyness required to
175 make LWP non-blocking.
176 - should work with perl 5.9.x now (Andreas König made me do it).
177 - fixed another bug in Coro::Select when the timeout was undef.
178 - reuse PL_start_env for all coros, saves some memory per coroutine.
179 - manage PL_top_env differently, hopefully to avoid panic: top_env.
180 - timeout argument was not properly used in Coro::Socket.
181 - allow limited forms of subclassing in Coro::Handle/Coro::Socket.
182 - emulate undocumented(!) functionality of IO::Socket required
183 by LWP(!!).
184 - updated eg/lwp to work with newer lwp's.
185 - remove "FATAL: uncaught exception" prefix. Coroutines that die
186 kill the whole process, just as exceptions in the main "coroutine"
187 did already.
188
1892.1 Wed Nov 1 23:01:13 CET 2006
190 - fix a long-standing bug in Coro::Select where select with
191 zero timeout would instead change the current default filehandle.
192 - use a simpler and hopefully more robust way to clone padlists
193 (uses less memory and a perl function instead of our own).
194 - coro can now create a stack guard area on many architectures.
195 - Coro::AIO properly reexports additional functions from IO::AIO.
196 - updated libcoro with a workaround for OS X,
197 pach and testing by Michael Schwern.
198
1992.0 Tue Oct 24 05:47:17 CEST 2006
200 - support additional aio requests in Coro::AIO.
201
2021.9 (never properly released due to a glitch)
203
2041.8 Thu Feb 2 00:59:06 CET 2006
205 - applied suggested patch by SAMV to avoid problems during stupid
206 mark & sweep gc run.
207 - applied patch by Scott Walters for 5.9.3 compatibility.
208
2091.7 Tue Dec 27 01:41:58 CET 2005
210 - added Coro::AIO, a thin wrapper around IO::AIO.
211 - improved Makefile.PL explanations.
212
2131.6 Mon Dec 12 21:30:05 CET 2005
214 - additionally save PM_curpm might fix as-of-yet
215 unseen problems with regex matches being attributed to the
216 wrong package.
217 - add t/10_bugs.t, which currently checks against imho broken
218 perls that use 0.26MB of stack space per Perl_magic_get
219 invocation (newer linuxes) as opposed to the 0.0002MB perl
220 normally uses.
221 - make stacksize configurable for the ultimate debian experience.
222
2231.51 Mon Dec 12 18:48:36 CET 2005
224 - remove debugging warn() accidentally left in Coro::Select.
225
2261.5 Tue Nov 29 13:32:44 CET 2005
227 - use Coro::Event inside Coro::Select to avoid spurious deadlocks.
228 - fix Coro::Select 'select'.
229 - strict'ify some modules.
230 - libcoro errornously restored the SIGUSR2 handler to SIGUSR1.
231 - use XSLoader in selected modules.
232 - remove some 5.6 compatibility cruft.
233
2341.4 Tue Sep 6 00:11:05 CEST 2005
235 - libcoro did not take into account the trampoline on amd64,
236 when 'l'inux method was used.
237
2381.31 Tue Aug 30 23:31:33 CEST 2005
239 - some portability fixes/workarounds.
240
2411.3 Sat Aug 20 03:08:56 CEST 2005
242 - no code changes. module seems to work fine.
243 - improve Coro::State docs, remove reference to nonexisting
244 Coro::State::flush method.
245 - no longer autodetect windows, present it as an option instead.
246
2471.2 Mon May 16 02:00:55 CEST 2005
248 - included libcoro.c earlier in State.xs, might improve portability.
249 - use a faster and possibly more stable Coro::Cont implementation.
250 - accept x86_64 in addition to amd64 for optimized linux-amd64 support.
251 - fix bugs Coro::SemaphoreSet that could cause locks never to be freed.
252 - fix bugs in CoroAPI.h and document it in Coro::MakeMaker.
253
2541.11 Thu Mar 3 18:00:52 CET 2005
255 - change of contact address.
256
2571.1 Tue Feb 22 20:51:16 CET 2005
258 - support [l]inux method on amd64.
259 - allow some context switches while compiling/eval'ing.
260
2611.0 Tue Aug 10 03:47:27 CEST 2004
262 - Event 0.89 fixes the bug again.
263 - fix the remaining(??) memleak. I didn't free the cache-AV for
264 padlists, so one AV per created anon-sub leaked.
265
2660.97 Fri May 14 15:23:32 CEST 2004
267 - remove stupid gcc extension that was an experiment only anyway.
268
2690.96 Thu May 13 18:09:29 CEST 2004
270 - tell people if they have yet another broken Event variant.
271 - made Coro to work _better_ with threads (it seems that, as long
272 as you use Coros in one thread only everything will work fine.
273 Looking at the perl source the problem might be missing locking
274 between Coro and some perl internal routines. That's not easily
275 fixable).
276 - (hopefully) got rid of the static xnext inside transfer.
277
2780.95 Sun Feb 15 03:20:28 CET 2004
279 - removed Coro::State::flush, implemented a new and much
280 faster caching mechanism by attaching magic to the CV.
281 - a memleak with (real) closures remains.
282 - dramatically reduced size of stacks to 65536 (linux/x86), after
283 observing that even myhttpd never had more than a kilobyte
284 of stack in use (stack is still only physically allocated in
285 pagesize increments for systems suporting mmap).
286 - fix for a "cygwin-64" architecture added, proposed by Stefan Traby.
287 - fix for threaded perl.
2 288
30.9 Sun Nov 23 04:32:39 CET 2003 2890.9 Sun Nov 23 04:32:39 CET 2003
4 - fix a few very hard to track down but (of course) stupid 290 - fix a few very hard to track down but (of course) stupid
5 memory leaks. 291 memory leaks.
6 - stringify version number to avoid locale problems :(. 292 - stringify version number to avoid locale problems :(.
