7 7
84.0 8 - tune 01_unblock.t tests a bit.
9 - support -fno-omit-frame-pointer on x86 with the assembly method.
10
114.801 Wed Oct 22 18:33:37 CEST 2008
12 - improve readline speed for very long "lines".
13 - backport to 5.8.8.
14
154.8 Thu Oct 2 13:34:40 CEST 2008
16 - new function Coro::AIO::aio_wait.
17 - Coro.:AIO and Coro::BDB now "use Coro::AnyEvent".
18 - greatly speed up and reduce memory usage of Coro::AIO requests.
19 - implement some other µ-optimisations.
20
214.749 Mon Sep 29 14:40:12 CEST 2008
22 - port to slow and broken pseudo-threaded perls. (courtesy pippijn).
23
244.748 Sat Sep 27 14:03:19 CEST 2008
25 - implement, but do not document, PerlIO::cede(granularity).
26 - Coro::Storable forgot to wrap Storable::pstore.
27 - work around the multitude of leaks and memory corruption
28 bugs in PerlIO::via by using our own C-level perliol. As a side
29 effect, Coro::Storable is now much, much, much faster.
30
314.747 Tue Sep 23 01:59:41 CEST 2008
32 - fix a per-cv memleak (one empty array was leaked per
33 code reference).
34 - avoid a crash in coro->call|rss when the coroutine was already
35 destroyed (most noticably when using Coro::Debug::ps :)
36 - also protect *Storable::FILE.
37 - push up default storable granularity to 20ms.
38
394.746 Sun Sep 21 03:22:20 CEST 2008
40 - be more insistent on locking Storable against reentrancy
41 in Coro::Storable.
42 - move swap_def?v and throw to Coro::State, as documented.
43
444.745 Thu Jul 24 00:14:38 CEST 2008
45 - remove debugging code related to MgPV_nolen_const, also try to
46 make it compile with perl 5.8.6 (yes, apple apparently loves
47 outdated software). Reported by John S.
48
494.744 Tue Jul 8 22:06:35 CEST 2008
50 - correctly provide default DIE/WARN handlers as documented.
51 - also overwrite PL_vtbl_sigelem.svt_clear, even though current
52 implementations inside perl work fine for us.
53
544.743 Mon Jun 16 00:21:57 CEST 2008
55 - when using Coro::EV without running EV::loop it could
56 result in busy-waiting for events, this has been fixed.
57 - reduce codesize and improve performance by using EV_DEFAULT_UC.
58
594.742 Sat May 31 14:10:21 CEST 2008
60 - implement a workaround for (some) perl <5.8.8 versions.
61 - require EV 3.3+.
62
634.741 Fri May 30 23:33:09 CEST 2008
64 - tell netbsd how utterly broken their imitation of an OS is
65 and refuse to build by default if pthreads are in use.
66 - switch to "s" method on all bsd's by default, as their ucontext
67 stuff seems just too broken.
68 - fix a bug in Coro::Select.
69
704.74 Thu May 29 20:05:31 CEST 2008
71 - do not test Coro::LWP for lack of dependencies.
72 - do not test Coro::Select for lack of working perls.
73
744.73 Thu May 29 2008
75 - fix a bug in Coro::EV which would cause it to block despite
76 there being runnable coroutines.
77 - sprinkle "no warnings" freely over everything, also suppress
78 warnings for some other modules.
79 - fix typo in WSAEWOULDBLOCK.
80
814.72 Sun May 25 05:14:36 CEST 2008
82 - tweak META.yaml a bit, unfortunately, there is no documented way
83 to have optional dependencies with CPAN. doh :(
84 - avoid running some tests on windows because they would fail due to
85 perl bug (broken fork, broken pipes...).
86 - work around perl on windows bugs where perl returns undocumented
87 error codes for sysread, syswrite etc. by taking advantage
88 of AnyEvent's workaround for that problem.
89 - use AnyEvent::Util::fh_nonblocking in Coro::Handle to work around
90 a common perl implementation bug on windows.
91 - use unix domain sockets in testsuite to work around
92 common perl implementation bugs on widows (they are emulated by
93 tcp sockets on windows. ugh.)
94
954.71 Sat May 24 20:01:27 CEST 2008
96 - fix a bug in Coro::AnyEvent ("Usage: Coro::AnyEvent::_schedule()").
97 - take advantage of async name resolution of AnyEvent::Util.
98 - work around brutal inet_aton override in Coro::LWP.
99 - take advantage of the readyhook in Coro::EV, for smoother
100 scheduling.
101
1024.7 Sun May 11 00:32:19 CEST 2008
103 - completely reworked the Coro manpage.
104 - added Coro::AnyEvent, generic event loop integration.
105 - implement cancel, ready and kill commands in Coro::Debug.
106 - document find_coro in Coro::Debug.
107 - incompatible change: rename has_stack to has_cctx.
108 - Coro::AIO and Coro::BDB no longer force event model detection,
109 use AnyEvent::AIO and AnyEvent::BDB.
110
1114.6 Sat Apr 26 10:05:14 CEST 2008
112 - INCOMPATIBLE CHANGE: sub/code attributes are no longer supported
113 by the Coro module. It was a mistake to have it in the first place.
114 - (experimental) support for activestate perl 5.10 (method "w").
115 - (experimental) support for strawberry perl (method "a").
116 - coro_sigelem_set did not return a value although it had to,
117 actual impact unknown.
118
1194.51 Mon Apr 14 13:28:27 CEST 2008
120 - make it compile again on 5.8.
121
1224.50 Thu Apr 10 09:43:17 CEST 2008
123 - I did it twice! (see 4.49).
124
1254.49 Sun Apr 6 21:23:31 CEST 2008
126 - grr, instead of compiling the recent changes on 5.10 only they
127 were compiled on 5.8 only.
128
1294.48 Sun Apr 6 20:36:46 CEST 2008
130 - allow coroutine switches during eval's under 5.10.x, as it seems
131 the parser is a per-interpreter option now, so this is safe
132 (this might fix the odd crashing bug).
133 - drop support for 5.9.x versions: they are dead, jim.
134
1354.47 Sun Apr 6 00:37:52 CEST 2008
136 - force cctx allocation on API calls: we know we need to force one
137 and gcc actually manages to confuse our heuristic nowadays,
138 leading to crashes and worse.
139 - document force_cctx.
140
1414.46 Fri Apr 4 22:05:43 CEST 2008
142 - upgrade libcoro, resulting in pthread-backend (which was only created
143 to fulfill the rules of the programming languages shootout).
144
1454.45 Thu Mar 13 11:55:36 CET 2008
146 - fix a file leaking bug in eg/mhyttpd that would allow
147 downloading of any file (reported by oesi).
148 - fix deadlock bug in Coro::Channel (reported by Richard Hundt)
149 (also add testcase).
150 - support Broadcast option in Coro::Socket (patch by Richard Hundt,
151 apparently having loads of fun with that).
152 - implement $state->swap_defsv, ->swap_defav and document ->throw.
153
1544.4 Wed Feb 13 16:44:29 CET 2008
155 - only assume .cfi pseudo isns exist on GNU/Linux.
156 - add get_timed method to Coro::Channels.
157 - fixed Coro::Debug manpage.
158 - perl 5.11 compatbility improvement based on patch by
159 Andreas König.
160
1614.37 Sun Jan 20 11:25:23 CET 2008
162 - soften the check for an active parser for perl 5.10 (avoiding
163 "Coro::State::transfer called while parsing" in many cases).
164
1654.36 Sun Jan 13 10:53:56 CET 2008
166 - reset diehook when terminating from an async_pool as to not
167 trigger any __DIE__ handlers.
168
1694.35 Sun Jan 13 04:14:13 CET 2008
170 - "bt" debug command now displays any exceptions
171 from longmess and also skips the innermost
172 stackframes, giving more useufl output.
173 - allow backtraces in coroutines blocked in Coro::EV,
174 at a <1% speed hit.
175 - handle localising of $SIG{__WARN__} and __DIE__
176 properly (with a proper amount of dirty hacking).
177
1784.34 Sat Dec 22 17:49:53 CET 2007
179 - upgrade to EV version 2.0 API.
180
1814.33 Mon Dec 17 08:36:12 CET 2007
182 - make Coro::AIO etc. loadable in the absence of EV.
183
1844.32 Mon Dec 17 07:46:02 CET 2007
185 - majorly improved Coro::Handle's performance with Coro::EV.
186 - implemented the until now mythical Coro::BDB module.
187 - specialcase EV in Coro::AIO and Coro::BDB for extra speed.
188
1894.31 Wed Dec 5 12:32:39 CET 2007
190 - remove warn statement form Coro::Util.
191
1924.3 Tue Dec 4 20:33:14 CET 2007
193 - calls to the idle function could cause stack corruption
194 when the stack changed.
195 - do no longer rely on the presence of EV::DNS if EV is used
196 (because it is gone), but instead take avdantage of EV::ADNS
197 if available.
198 - add ($) prototypes to all functions in Coro::Storable.
199 - use a conventional (safer) idle callback in Coro::EV.
200 - do accept quickly in Coro::Debug to avoid endless loops.
201
2024.22 Fri Nov 30 16:04:04 CET 2007
203 - really use optimised versions for Event and EV in Coro::Util
204 and Coro::Handle.
205
2064.21 Sun Nov 25 10:48:59 CET 2007
207 - fix a spurious memory read.
208 - Coro::EV no longer keeps the eventloop "alive".
209
2104.2 Fri Nov 9 20:47:05 CET 2007
211 - enable/disable tracing from a new coroutine, not a pooled one.
212 - fix a memleak in Coro::Event.
213 - removed killall call from fork_eval.
214 - made sure store_fd is already loaded so that fork_eval
215 does not have to parse autoload in each subprocess.
216 - only use assembly method if -O switch is in $Config{optimize}.
217 - add (optional) Coro::EV module, so far the best event loop module
218 directly supported by Coro.
219 - if the event model is EV, use EV::DNS to resolve
220 stuff in Coro::Util.
221 - don't get confused by multiple event notifications in Coro::Handle.
222 - initial support for EV (libevent interface).
223 - require Event and EV using configure_requires, to force their existance.
224
2254.13 Wed Oct 24 07:26:45 CEST 2007
226 - add Coro::Storable::blocking_thaw.
227 - use a vastly more complicated technique to localise
228 $SIG{__WARN/DIE__} that also works on perls <= 5.8.8.
229 - use a coroutine for the idle callback Coro::Event,
230 instead of running Event in the current coroutine context.
231 This also catches recursive invocations.
232 - actually report fork errors in gethostbyname and inet_aton.
233
2344.11 Thu Oct 11 02:40:24 CEST 2007
235 - port to threaded perls.
236
2374.1 Thu Oct 11 02:38:16 CEST 2007
238 - incompatible change: $SIG{__DIE__} and $SIG{__WARN__} will now
239 be local to each coro (see Coro::State).
240 - incompatible change: for very deep reasons, cede and cede_notself
241 cannot return anything, so nothing will be returned.
242 - possibly bring back 5.10 compatibility (untested).
243 - work around stupid (and wrong) warning on 5.10 :(.
244 - overlay the saved state over the context stack. This saves
245 a few hundred bytes per coroutine on average and also
246 speeds up context switching a bit.
247 - further tune default stack sizes.
248 - (more) correctly calculate stack usage in coro_rss.
249 - Coro::Storable::blocking_* did not properly lock
250 resulting in races between coroutines.
251 - added Coro::Storable::guard.
252 - stopping to trace a coroutine could destroy the cctx of
253 an unrelated coroutine.
254 - explain the relationship between Perl and C coroutines in
255 more detail in Coro::State.
256 - Coro::Util::inet_aton did not short-circuit dotted quad forms,
257 causing a fork per resolve. This also affected Coro::Socket.
258 - switch to a separate stack in $coro->call/eval to avoid
259 invalidating pointers.
260
2614.03 Sat Oct 6 21:24:00 CEST 2007
262 - added Coro::throw method.
263 - minor code cleanups.
264
2654.02 Sat Oct 6 02:36:47 CEST 2007
266 - fix a very minor per-coroutine memleak (a single codereference).
267 - fixed a bug where the currently in-use c context would be freed
268 prematurely (can happen only when programs change the stacksize
269 or use tracing).
270 - tracing can no longer keep a coro alive after it terminated.
271 - do static branch prediction in the common path for gcc. gives
272 about 2-5% speed improvement here.
273
2744.01 Fri Oct 5 22:10:49 CEST 2007
275 - instead of recreating *a* standard output handle we simply
276 use STDOUT, which is faster and hopefully more robust.
277
2784.0 Fri Oct 5 12:56:00 CEST 2007
9 - incompatibly changed Coro::Storable::freeze. 279 - incompatibly changed Coro::Storable::freeze.

12 - unbelievable, but true: $_, $@ and many other "saved" variables 282 - major bug fix: unbelievable, but true: $_, $/ and many other
13 actually weren't being saved. This has been fixed, of course, 283 "saved" variables actually weren't being saved. This has been fixed,
14 while increasing performance while losing all the save flags. 284 of course, while increasing performance while losing all the save
285 flags.
15 - save flags are gone, and all the api functions dealing with them. 286 - save flags are gone, and all the api functions dealing with them.
