2 2
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)).
5 7
63.51 8 - move swap_def?v and throw to Coro::State, as documented.
9
104.745 Thu Jul 24 00:14:38 CEST 2008
11 - remove debugging code related to MgPV_nolen_const, also try to
12 make it compile with perl 5.8.6 (yes, apple apparently loves
13 outdated software). Reported by John S.
14
154.744 Tue Jul 8 22:06:35 CEST 2008
16 - correctly provide default DIE/WARN handlers as documented.
17 - also overwrite PL_vtbl_sigelem.svt_clear, even though current
18 implementations inside perl work fine for us.
19
204.743 Mon Jun 16 00:21:57 CEST 2008
21 - when using Coro::EV without running EV::loop it could
22 result in busy-waiting for events, this has been fixed.
23 - reduce codesize and improve performance by using EV_DEFAULT_UC.
24
254.742 Sat May 31 14:10:21 CEST 2008
26 - implement a workaround for (some) perl <5.8.8 versions.
27 - require EV 3.3+.
28
294.741 Fri May 30 23:33:09 CEST 2008
30 - tell netbsd how utterly broken their imitation of an OS is
31 and refuse to build by default if pthreads are in use.
32 - switch to "s" method on all bsd's by default, as their ucontext
33 stuff seems just too broken.
34 - fix a bug in Coro::Select.
35
364.74 Thu May 29 20:05:31 CEST 2008
37 - do not test Coro::LWP for lack of dependencies.
38 - do not test Coro::Select for lack of working perls.
39
404.73 Thu May 29 2008
41 - fix a bug in Coro::EV which would cause it to block despite
42 there being runnable coroutines.
43 - sprinkle "no warnings" freely over everything, also suppress
44 warnings for some other modules.
45 - fix typo in WSAEWOULDBLOCK.
46
474.72 Sun May 25 05:14:36 CEST 2008
48 - tweak META.yaml a bit, unfortunately, there is no documented way
49 to have optional dependencies with CPAN. doh :(
50 - avoid running some tests on windows because they would fail due to
51 perl bug (broken fork, broken pipes...).
52 - work around perl on windows bugs where perl returns undocumented
53 error codes for sysread, syswrite etc. by taking advantage
54 of AnyEvent's workaround for that problem.
55 - use AnyEvent::Util::fh_nonblocking in Coro::Handle to work around
56 a common perl implementation bug on windows.
57 - use unix domain sockets in testsuite to work around
58 common perl implementation bugs on widows (they are emulated by
59 tcp sockets on windows. ugh.)
60
614.71 Sat May 24 20:01:27 CEST 2008
62 - fix a bug in Coro::AnyEvent ("Usage: Coro::AnyEvent::_schedule()").
63 - take advantage of async name resolution of AnyEvent::Util.
64 - work around brutal inet_aton override in Coro::LWP.
65 - take advantage of the readyhook in Coro::EV, for smoother
66 scheduling.
67
684.7 Sun May 11 00:32:19 CEST 2008
69 - completely reworked the Coro manpage.
70 - added Coro::AnyEvent, generic event loop integration.
71 - implement cancel, ready and kill commands in Coro::Debug.
72 - document find_coro in Coro::Debug.
73 - incompatible change: rename has_stack to has_cctx.
74 - Coro::AIO and Coro::BDB no longer force event model detection,
75 use AnyEvent::AIO and AnyEvent::BDB.
76
774.6 Sat Apr 26 10:05:14 CEST 2008
78 - INCOMPATIBLE CHANGE: sub/code attributes are no longer supported
79 by the Coro module. It was a mistake to have it in the first place.
80 - (experimental) support for activestate perl 5.10 (method "w").
81 - (experimental) support for strawberry perl (method "a").
82 - coro_sigelem_set did not return a value although it had to,
83 actual impact unknown.
84
854.51 Mon Apr 14 13:28:27 CEST 2008
86 - make it compile again on 5.8.
87
884.50 Thu Apr 10 09:43:17 CEST 2008
89 - I did it twice! (see 4.49).
90
914.49 Sun Apr 6 21:23:31 CEST 2008
92 - grr, instead of compiling the recent changes on 5.10 only they
93 were compiled on 5.8 only.
94
954.48 Sun Apr 6 20:36:46 CEST 2008
96 - allow coroutine switches during eval's under 5.10.x, as it seems
97 the parser is a per-interpreter option now, so this is safe
98 (this might fix the odd crashing bug).
99 - drop support for 5.9.x versions: they are dead, jim.
100
1014.47 Sun Apr 6 00:37:52 CEST 2008
102 - force cctx allocation on API calls: we know we need to force one
103 and gcc actually manages to confuse our heuristic nowadays,
104 leading to crashes and worse.
105 - document force_cctx.
106
1074.46 Fri Apr 4 22:05:43 CEST 2008
108 - upgrade libcoro, resulting in pthread-backend (which was only created
109 to fulfill the rules of the programming languages shootout).
110
1114.45 Thu Mar 13 11:55:36 CET 2008
112 - fix a file leaking bug in eg/mhyttpd that would allow
113 downloading of any file (reported by oesi).
114 - fix deadlock bug in Coro::Channel (reported by Richard Hundt)
115 (also add testcase).
116 - support Broadcast option in Coro::Socket (patch by Richard Hundt,
117 apparently having loads of fun with that).
118 - implement $state->swap_defsv, ->swap_defav and document ->throw.
119
1204.4 Wed Feb 13 16:44:29 CET 2008
121 - only assume .cfi pseudo isns exist on GNU/Linux.
122 - add get_timed method to Coro::Channels.
123 - fixed Coro::Debug manpage.
124 - perl 5.11 compatbility improvement based on patch by
125 Andreas König.
126
1274.37 Sun Jan 20 11:25:23 CET 2008
128 - soften the check for an active parser for perl 5.10 (avoiding
129 "Coro::State::transfer called while parsing" in many cases).
130
1314.36 Sun Jan 13 10:53:56 CET 2008
132 - reset diehook when terminating from an async_pool as to not
133 trigger any __DIE__ handlers.
134
1354.35 Sun Jan 13 04:14:13 CET 2008
136 - "bt" debug command now displays any exceptions
137 from longmess and also skips the innermost
138 stackframes, giving more useufl output.
139 - allow backtraces in coroutines blocked in Coro::EV,
140 at a <1% speed hit.
141 - handle localising of $SIG{__WARN__} and __DIE__
142 properly (with a proper amount of dirty hacking).
143
1444.34 Sat Dec 22 17:49:53 CET 2007
145 - upgrade to EV version 2.0 API.
146
1474.33 Mon Dec 17 08:36:12 CET 2007
148 - make Coro::AIO etc. loadable in the absence of EV.
149
1504.32 Mon Dec 17 07:46:02 CET 2007
151 - majorly improved Coro::Handle's performance with Coro::EV.
152 - implemented the until now mythical Coro::BDB module.
153 - specialcase EV in Coro::AIO and Coro::BDB for extra speed.
154
1554.31 Wed Dec 5 12:32:39 CET 2007
156 - remove warn statement form Coro::Util.
157
1584.3 Tue Dec 4 20:33:14 CET 2007
159 - calls to the idle function could cause stack corruption
160 when the stack changed.
161 - do no longer rely on the presence of EV::DNS if EV is used
162 (because it is gone), but instead take avdantage of EV::ADNS
163 if available.
164 - add ($) prototypes to all functions in Coro::Storable.
165 - use a conventional (safer) idle callback in Coro::EV.
166 - do accept quickly in Coro::Debug to avoid endless loops.
167
1684.22 Fri Nov 30 16:04:04 CET 2007
169 - really use optimised versions for Event and EV in Coro::Util
170 and Coro::Handle.
171
1724.21 Sun Nov 25 10:48:59 CET 2007
173 - fix a spurious memory read.
174 - Coro::EV no longer keeps the eventloop "alive".
175
1764.2 Fri Nov 9 20:47:05 CET 2007
177 - enable/disable tracing from a new coroutine, not a pooled one.
178 - fix a memleak in Coro::Event.
179 - removed killall call from fork_eval.
180 - made sure store_fd is already loaded so that fork_eval
181 does not have to parse autoload in each subprocess.
182 - only use assembly method if -O switch is in $Config{optimize}.
183 - add (optional) Coro::EV module, so far the best event loop module
184 directly supported by Coro.
185 - if the event model is EV, use EV::DNS to resolve
186 stuff in Coro::Util.
187 - don't get confused by multiple event notifications in Coro::Handle.
188 - initial support for EV (libevent interface).
189 - require Event and EV using configure_requires, to force their existance.
190
1914.13 Wed Oct 24 07:26:45 CEST 2007
192 - add Coro::Storable::blocking_thaw.
193 - use a vastly more complicated technique to localise
194 $SIG{__WARN/DIE__} that also works on perls <= 5.8.8.
195 - use a coroutine for the idle callback Coro::Event,
196 instead of running Event in the current coroutine context.
197 This also catches recursive invocations.
198 - actually report fork errors in gethostbyname and inet_aton.
199
2004.11 Thu Oct 11 02:40:24 CEST 2007
201 - port to threaded perls.
202
2034.1 Thu Oct 11 02:38:16 CEST 2007
204 - incompatible change: $SIG{__DIE__} and $SIG{__WARN__} will now
205 be local to each coro (see Coro::State).
206 - incompatible change: for very deep reasons, cede and cede_notself
207 cannot return anything, so nothing will be returned.
208 - possibly bring back 5.10 compatibility (untested).
209 - work around stupid (and wrong) warning on 5.10 :(.
210 - overlay the saved state over the context stack. This saves
211 a few hundred bytes per coroutine on average and also
212 speeds up context switching a bit.
213 - further tune default stack sizes.
214 - (more) correctly calculate stack usage in coro_rss.
215 - Coro::Storable::blocking_* did not properly lock
216 resulting in races between coroutines.
217 - added Coro::Storable::guard.
218 - stopping to trace a coroutine could destroy the cctx of
219 an unrelated coroutine.
220 - explain the relationship between Perl and C coroutines in
221 more detail in Coro::State.
222 - Coro::Util::inet_aton did not short-circuit dotted quad forms,
223 causing a fork per resolve. This also affected Coro::Socket.
224 - switch to a separate stack in $coro->call/eval to avoid
225 invalidating pointers.
226
2274.03 Sat Oct 6 21:24:00 CEST 2007
228 - added Coro::throw method.
229 - minor code cleanups.
230
2314.02 Sat Oct 6 02:36:47 CEST 2007
232 - fix a very minor per-coroutine memleak (a single codereference).
233 - fixed a bug where the currently in-use c context would be freed
234 prematurely (can happen only when programs change the stacksize
235 or use tracing).
236 - tracing can no longer keep a coro alive after it terminated.
237 - do static branch prediction in the common path for gcc. gives
238 about 2-5% speed improvement here.
239
2404.01 Fri Oct 5 22:10:49 CEST 2007
241 - instead of recreating *a* standard output handle we simply
242 use STDOUT, which is faster and hopefully more robust.
243
2444.0 Fri Oct 5 12:56:00 CEST 2007
245 - incompatibly changed Coro::Storable::freeze.
246 - major new feature: added Coro::Debug, for interactive coroutine
247 debugging, tracing and much more.
248 - major bug fix: unbelievable, but true: $_, $/ and many other
249 "saved" variables actually weren't being saved. This has been fixed,
250 of course, while increasing performance while losing all the save
251 flags.
252 - save flags are gone, and all the api functions dealing with them.
253 - added Coro::Semaphore::adjust.
254 - added Coro::Util::fork_eval.
255 - added Coro::Storable::{nfreeze,blocking_{freeze,nfreeze}}.
256 - added Coro::killall.
257 - reduce initial stack sizes to allow for "micro-coroutines".
258 - better async_pool resource management, moved parts of async_pool
259 handling to XS (major speed improvement).
260 - actually croak before modifying important data structures.
261 - refuse to transfer while compiling.
262 - possibly support eval EXPR better now.
263 - enable assembly per default on linux+bsd x86+amd64.
264 - all internal members were renamed _something for easier subclassing.
265 - many minor tweaks.
266
2673.63 Wed May 16 14:10:06 CEST 2007
268 - implement handcoded assembly for x86/amd64 SVR ABI.
269
2703.62 Fri Apr 27 21:36:06 CEST 2007
271 - upgrade libcoro (which might set unwind info correctly).
272 - change default on linux to setjmp/longjmp.
273
2743.61 Thu Apr 19 12:36:18 CEST 2007
275 - Coro::Storable caused an endless loop when thawing invalid
276 pst's sometimes.
277 - use a Semaphore in Coro::Storable, as Storable doesn't
278 seem to be reentrant (although it is documented to
279 be threadsafe...).
280 - fix Coro::Signal to bring back the original unreliable
281 but stateful semantics.
282 - fixed a lot of typos in Coro.pm (patch submitted by David
283 Steinbrunner, which applied flawlessly).
284
2853.6 Sat Apr 14 17:13:31 CEST 2007
286 - added some bugfixes to get eg/myhttpd working again.
287 - added Coro::Storable for often-cede'ing freeze/thaw.
288 - try to do a clean exit when a coroutine calls exit
289 (EXPERIMENTAL).
290 - got rid of indirect call through _coro_init.
291 - updated the partly antique examples in eg/ to
292 work again and be a bit less magic, too.
293 - fixed Coro::Signal semantics to work as documented again.
294
2953.55 Sun Mar 25 01:20:47 CET 2007
296 - add SAVE_DEFFH to save the default filehandle and enable
297 it by default.
298 - finally move socket-operations from Coro::Socket to Coro::Handle
299 to be able to unblock foreign sockets.
300 - add Coro::State::save_also and guarded_save.
301 - add count accessor to Coro::Semaphore.
302 - add Coro::State::cctx_stacksize.
303 - just for the fun of it, do not rely on implicit context,
304 which can dramatically improve performance, but people
305 using windows-process-emulation perls do not care much about
306 performance.
307
3083.51 Sun Mar 4 14:18:04 CET 2007
7 - fixed a problem when you weakened references to Coro::State's 309 - fixed a problem when you weakened references to Coro::State's
8 (patch by Yuval Kogman). 310 (patch by Yuval Kogman).
