83.8 84.8
9 - new function Coro::AIO::aio_wait.
10 - Coro.:AIO and Coro::BDB now "use Coro::AnyEvent".
11 - greatly speed up and reduce memory usage of Coro::AIO requests.
12
134.749 Mon Sep 29 14:40:12 CEST 2008
14 - port to slow and broken pseudo-threaded perls. (courtesy pippijn).
15
164.748 Sat Sep 27 14:03:19 CEST 2008
17 - implement, but do not document, PerlIO::cede(granularity).
18 - Coro::Storable forgot to wrap Storable::pstore.
19 - work around the multitude of leaks and memory corruption
20 bugs in PerlIO::via by using our own C-level perliol. As a side
21 effect, Coro::Storable is now much, much, much faster.
22
234.747 Tue Sep 23 01:59:41 CEST 2008
24 - fix a per-cv memleak (one empty array was leaked per
25 code reference).
26 - avoid a crash in coro->call|rss when the coroutine was already
27 destroyed (most noticably when using Coro::Debug::ps :)
28 - also protect *Storable::FILE.
29 - push up default storable granularity to 20ms.
30
314.746 Sun Sep 21 03:22:20 CEST 2008
32 - be more insistent on locking Storable against reentrancy
33 in Coro::Storable.
34 - move swap_def?v and throw to Coro::State, as documented.
35
364.745 Thu Jul 24 00:14:38 CEST 2008
37 - remove debugging code related to MgPV_nolen_const, also try to
38 make it compile with perl 5.8.6 (yes, apple apparently loves
39 outdated software). Reported by John S.
40
414.744 Tue Jul 8 22:06:35 CEST 2008
42 - correctly provide default DIE/WARN handlers as documented.
43 - also overwrite PL_vtbl_sigelem.svt_clear, even though current
44 implementations inside perl work fine for us.
45
464.743 Mon Jun 16 00:21:57 CEST 2008
47 - when using Coro::EV without running EV::loop it could
48 result in busy-waiting for events, this has been fixed.
49 - reduce codesize and improve performance by using EV_DEFAULT_UC.
50
514.742 Sat May 31 14:10:21 CEST 2008
52 - implement a workaround for (some) perl <5.8.8 versions.
53 - require EV 3.3+.
54
554.741 Fri May 30 23:33:09 CEST 2008
56 - tell netbsd how utterly broken their imitation of an OS is
57 and refuse to build by default if pthreads are in use.
58 - switch to "s" method on all bsd's by default, as their ucontext
59 stuff seems just too broken.
60 - fix a bug in Coro::Select.
61
624.74 Thu May 29 20:05:31 CEST 2008
63 - do not test Coro::LWP for lack of dependencies.
64 - do not test Coro::Select for lack of working perls.
65
664.73 Thu May 29 2008
67 - fix a bug in Coro::EV which would cause it to block despite
68 there being runnable coroutines.
69 - sprinkle "no warnings" freely over everything, also suppress
70 warnings for some other modules.
71 - fix typo in WSAEWOULDBLOCK.
72
734.72 Sun May 25 05:14:36 CEST 2008
74 - tweak META.yaml a bit, unfortunately, there is no documented way
75 to have optional dependencies with CPAN. doh :(
76 - avoid running some tests on windows because they would fail due to
77 perl bug (broken fork, broken pipes...).
78 - work around perl on windows bugs where perl returns undocumented
79 error codes for sysread, syswrite etc. by taking advantage
80 of AnyEvent's workaround for that problem.
81 - use AnyEvent::Util::fh_nonblocking in Coro::Handle to work around
82 a common perl implementation bug on windows.
83 - use unix domain sockets in testsuite to work around
84 common perl implementation bugs on widows (they are emulated by
85 tcp sockets on windows. ugh.)
86
874.71 Sat May 24 20:01:27 CEST 2008
88 - fix a bug in Coro::AnyEvent ("Usage: Coro::AnyEvent::_schedule()").
89 - take advantage of async name resolution of AnyEvent::Util.
90 - work around brutal inet_aton override in Coro::LWP.
91 - take advantage of the readyhook in Coro::EV, for smoother
92 scheduling.
93
944.7 Sun May 11 00:32:19 CEST 2008
95 - completely reworked the Coro manpage.
96 - added Coro::AnyEvent, generic event loop integration.
97 - implement cancel, ready and kill commands in Coro::Debug.
98 - document find_coro in Coro::Debug.
99 - incompatible change: rename has_stack to has_cctx.
100 - Coro::AIO and Coro::BDB no longer force event model detection,
101 use AnyEvent::AIO and AnyEvent::BDB.
102
1034.6 Sat Apr 26 10:05:14 CEST 2008
104 - INCOMPATIBLE CHANGE: sub/code attributes are no longer supported
105 by the Coro module. It was a mistake to have it in the first place.
106 - (experimental) support for activestate perl 5.10 (method "w").
107 - (experimental) support for strawberry perl (method "a").
108 - coro_sigelem_set did not return a value although it had to,
109 actual impact unknown.
110
1114.51 Mon Apr 14 13:28:27 CEST 2008
112 - make it compile again on 5.8.
113
1144.50 Thu Apr 10 09:43:17 CEST 2008
115 - I did it twice! (see 4.49).
116
1174.49 Sun Apr 6 21:23:31 CEST 2008
118 - grr, instead of compiling the recent changes on 5.10 only they
119 were compiled on 5.8 only.
120
1214.48 Sun Apr 6 20:36:46 CEST 2008
122 - allow coroutine switches during eval's under 5.10.x, as it seems
123 the parser is a per-interpreter option now, so this is safe
124 (this might fix the odd crashing bug).
125 - drop support for 5.9.x versions: they are dead, jim.
126
1274.47 Sun Apr 6 00:37:52 CEST 2008
128 - force cctx allocation on API calls: we know we need to force one
129 and gcc actually manages to confuse our heuristic nowadays,
130 leading to crashes and worse.
131 - document force_cctx.
132
1334.46 Fri Apr 4 22:05:43 CEST 2008
134 - upgrade libcoro, resulting in pthread-backend (which was only created
135 to fulfill the rules of the programming languages shootout).
136
1374.45 Thu Mar 13 11:55:36 CET 2008
138 - fix a file leaking bug in eg/mhyttpd that would allow
139 downloading of any file (reported by oesi).
140 - fix deadlock bug in Coro::Channel (reported by Richard Hundt)
141 (also add testcase).
142 - support Broadcast option in Coro::Socket (patch by Richard Hundt,
143 apparently having loads of fun with that).
144 - implement $state->swap_defsv, ->swap_defav and document ->throw.
145
1464.4 Wed Feb 13 16:44:29 CET 2008
147 - only assume .cfi pseudo isns exist on GNU/Linux.
148 - add get_timed method to Coro::Channels.
149 - fixed Coro::Debug manpage.
150 - perl 5.11 compatbility improvement based on patch by
151 Andreas König.
152
1534.37 Sun Jan 20 11:25:23 CET 2008
154 - soften the check for an active parser for perl 5.10 (avoiding
155 "Coro::State::transfer called while parsing" in many cases).
156
1574.36 Sun Jan 13 10:53:56 CET 2008
158 - reset diehook when terminating from an async_pool as to not
159 trigger any __DIE__ handlers.
160
1614.35 Sun Jan 13 04:14:13 CET 2008
162 - "bt" debug command now displays any exceptions
163 from longmess and also skips the innermost
164 stackframes, giving more useufl output.
165 - allow backtraces in coroutines blocked in Coro::EV,
166 at a <1% speed hit.
167 - handle localising of $SIG{__WARN__} and __DIE__
168 properly (with a proper amount of dirty hacking).
169
1704.34 Sat Dec 22 17:49:53 CET 2007
171 - upgrade to EV version 2.0 API.
172
1734.33 Mon Dec 17 08:36:12 CET 2007
174 - make Coro::AIO etc. loadable in the absence of EV.
175
1764.32 Mon Dec 17 07:46:02 CET 2007
177 - majorly improved Coro::Handle's performance with Coro::EV.
178 - implemented the until now mythical Coro::BDB module.
179 - specialcase EV in Coro::AIO and Coro::BDB for extra speed.
180
1814.31 Wed Dec 5 12:32:39 CET 2007
182 - remove warn statement form Coro::Util.
183
1844.3 Tue Dec 4 20:33:14 CET 2007
185 - calls to the idle function could cause stack corruption
186 when the stack changed.
187 - do no longer rely on the presence of EV::DNS if EV is used
188 (because it is gone), but instead take avdantage of EV::ADNS
189 if available.
190 - add ($) prototypes to all functions in Coro::Storable.
191 - use a conventional (safer) idle callback in Coro::EV.
192 - do accept quickly in Coro::Debug to avoid endless loops.
193
1944.22 Fri Nov 30 16:04:04 CET 2007
195 - really use optimised versions for Event and EV in Coro::Util
196 and Coro::Handle.
197
1984.21 Sun Nov 25 10:48:59 CET 2007
199 - fix a spurious memory read.
200 - Coro::EV no longer keeps the eventloop "alive".
201
2024.2 Fri Nov 9 20:47:05 CET 2007
203 - enable/disable tracing from a new coroutine, not a pooled one.
204 - fix a memleak in Coro::Event.
205 - removed killall call from fork_eval.
206 - made sure store_fd is already loaded so that fork_eval
207 does not have to parse autoload in each subprocess.
208 - only use assembly method if -O switch is in $Config{optimize}.
209 - add (optional) Coro::EV module, so far the best event loop module
210 directly supported by Coro.
211 - if the event model is EV, use EV::DNS to resolve
212 stuff in Coro::Util.
213 - don't get confused by multiple event notifications in Coro::Handle.
214 - initial support for EV (libevent interface).
215 - require Event and EV using configure_requires, to force their existance.
216
2174.13 Wed Oct 24 07:26:45 CEST 2007
218 - add Coro::Storable::blocking_thaw.
219 - use a vastly more complicated technique to localise
220 $SIG{__WARN/DIE__} that also works on perls <= 5.8.8.
221 - use a coroutine for the idle callback Coro::Event,
222 instead of running Event in the current coroutine context.
223 This also catches recursive invocations.
224 - actually report fork errors in gethostbyname and inet_aton.
225
2264.11 Thu Oct 11 02:40:24 CEST 2007
227 - port to threaded perls.
228
2294.1 Thu Oct 11 02:38:16 CEST 2007
230 - incompatible change: $SIG{__DIE__} and $SIG{__WARN__} will now
231 be local to each coro (see Coro::State).
232 - incompatible change: for very deep reasons, cede and cede_notself
233 cannot return anything, so nothing will be returned.
234 - possibly bring back 5.10 compatibility (untested).
235 - work around stupid (and wrong) warning on 5.10 :(.
236 - overlay the saved state over the context stack. This saves
237 a few hundred bytes per coroutine on average and also
238 speeds up context switching a bit.
239 - further tune default stack sizes.
240 - (more) correctly calculate stack usage in coro_rss.
241 - Coro::Storable::blocking_* did not properly lock
242 resulting in races between coroutines.
243 - added Coro::Storable::guard.
244 - stopping to trace a coroutine could destroy the cctx of
245 an unrelated coroutine.
246 - explain the relationship between Perl and C coroutines in
247 more detail in Coro::State.
248 - Coro::Util::inet_aton did not short-circuit dotted quad forms,
249 causing a fork per resolve. This also affected Coro::Socket.
250 - switch to a separate stack in $coro->call/eval to avoid
251 invalidating pointers.
252
2534.03 Sat Oct 6 21:24:00 CEST 2007
254 - added Coro::throw method.
255 - minor code cleanups.
256
2574.02 Sat Oct 6 02:36:47 CEST 2007
258 - fix a very minor per-coroutine memleak (a single codereference).
259 - fixed a bug where the currently in-use c context would be freed
260 prematurely (can happen only when programs change the stacksize
261 or use tracing).
262 - tracing can no longer keep a coro alive after it terminated.
263 - do static branch prediction in the common path for gcc. gives
264 about 2-5% speed improvement here.
265
2664.01 Fri Oct 5 22:10:49 CEST 2007
267 - instead of recreating *a* standard output handle we simply
268 use STDOUT, which is faster and hopefully more robust.
269
2704.0 Fri Oct 5 12:56:00 CEST 2007
9 - incompatibly changed Coro::Storable::freeze. 271 - incompatibly changed Coro::Storable::freeze.
10 - major new feature: added Coro::Debug, for interactive coroutine 272 - major new feature: added Coro::Debug, for interactive coroutine
11 debugging, tracing and much more. 273 debugging, tracing and much more.
274 - major bug fix: unbelievable, but true: $_, $/ and many other
275 "saved" variables actually weren't being saved. This has been fixed,
276 of course, while increasing performance while losing all the save
277 flags.
278 - save flags are gone, and all the api functions dealing with them.
12 - added Coro::Semaphore::adjust. 279 - added Coro::Semaphore::adjust.
13 - added Coro::Util::fork_eval. 280 - added Coro::Util::fork_eval.
14 - added Coro::Storable::{nfreeze,blocking_{freeze,nfreeze}}. 281 - added Coro::Storable::{nfreeze,blocking_{freeze,nfreeze}}.
15 - added Coro::killall. 282 - added Coro::killall.
16 - reduce initial stack sizes to allow for "micro-coroutines". 283 - reduce initial stack sizes to allow for "micro-coroutines".
