84.0 84.745 Thu Jul 24 00:14:38 CEST 2008
9 - remove debugging code related to MgPV_nolen_const, also try to
10 make it compile with perl 5.8.6 (yes, apple apparently loves
11 outdated software). Reported by John S.
12
134.744 Tue Jul 8 22:06:35 CEST 2008
14 - correctly provide default DIE/WARN handlers as documented.
15 - also overwrite PL_vtbl_sigelem.svt_clear, even though current
16 implementations inside perl work fine for us.
17
184.743 Mon Jun 16 00:21:57 CEST 2008
19 - when using Coro::EV without running EV::loop it could
20 result in busy-waiting for events, this has been fixed.
21 - reduce codesize and improve performance by using EV_DEFAULT_UC.
22
234.742 Sat May 31 14:10:21 CEST 2008
24 - implement a workaround for (some) perl <5.8.8 versions.
25 - require EV 3.3+.
26
274.741 Fri May 30 23:33:09 CEST 2008
28 - tell netbsd how utterly broken their imitation of an OS is
29 and refuse to build by default if pthreads are in use.
30 - switch to "s" method on all bsd's by default, as their ucontext
31 stuff seems just too broken.
32 - fix a bug in Coro::Select.
33
344.74 Thu May 29 20:05:31 CEST 2008
35 - do not test Coro::LWP for lack of dependencies.
36 - do not test Coro::Select for lack of working perls.
37
384.73 Thu May 29 2008
39 - fix a bug in Coro::EV which would cause it to block despite
40 there being runnable coroutines.
41 - sprinkle "no warnings" freely over everything, also suppress
42 warnings for some other modules.
43 - fix typo in WSAEWOULDBLOCK.
44
454.72 Sun May 25 05:14:36 CEST 2008
46 - tweak META.yaml a bit, unfortunately, there is no documented way
47 to have optional dependencies with CPAN. doh :(
48 - avoid running some tests on windows because they would fail due to
49 perl bug (broken fork, broken pipes...).
50 - work around perl on windows bugs where perl returns undocumented
51 error codes for sysread, syswrite etc. by taking advantage
52 of AnyEvent's workaround for that problem.
53 - use AnyEvent::Util::fh_nonblocking in Coro::Handle to work around
54 a common perl implementation bug on windows.
55 - use unix domain sockets in testsuite to work around
56 common perl implementation bugs on widows (they are emulated by
57 tcp sockets on windows. ugh.)
58
594.71 Sat May 24 20:01:27 CEST 2008
60 - fix a bug in Coro::AnyEvent ("Usage: Coro::AnyEvent::_schedule()").
61 - take advantage of async name resolution of AnyEvent::Util.
62 - work around brutal inet_aton override in Coro::LWP.
63 - take advantage of the readyhook in Coro::EV, for smoother
64 scheduling.
65
664.7 Sun May 11 00:32:19 CEST 2008
67 - completely reworked the Coro manpage.
68 - added Coro::AnyEvent, generic event loop integration.
69 - implement cancel, ready and kill commands in Coro::Debug.
70 - document find_coro in Coro::Debug.
71 - incompatible change: rename has_stack to has_cctx.
72 - Coro::AIO and Coro::BDB no longer force event model detection,
73 use AnyEvent::AIO and AnyEvent::BDB.
74
754.6 Sat Apr 26 10:05:14 CEST 2008
76 - INCOMPATIBLE CHANGE: sub/code attributes are no longer supported
77 by the Coro module. It was a mistake to have it in the first place.
78 - (experimental) support for activestate perl 5.10 (method "w").
79 - (experimental) support for strawberry perl (method "a").
80 - coro_sigelem_set did not return a value although it had to,
81 actual impact unknown.
82
834.51 Mon Apr 14 13:28:27 CEST 2008
84 - make it compile again on 5.8.
85
864.50 Thu Apr 10 09:43:17 CEST 2008
87 - I did it twice! (see 4.49).
88
894.49 Sun Apr 6 21:23:31 CEST 2008
90 - grr, instead of compiling the recent changes on 5.10 only they
91 were compiled on 5.8 only.
92
934.48 Sun Apr 6 20:36:46 CEST 2008
94 - allow coroutine switches during eval's under 5.10.x, as it seems
95 the parser is a per-interpreter option now, so this is safe
96 (this might fix the odd crashing bug).
97 - drop support for 5.9.x versions: they are dead, jim.
98
994.47 Sun Apr 6 00:37:52 CEST 2008
100 - force cctx allocation on API calls: we know we need to force one
101 and gcc actually manages to confuse our heuristic nowadays,
102 leading to crashes and worse.
103 - document force_cctx.
104
1054.46 Fri Apr 4 22:05:43 CEST 2008
106 - upgrade libcoro, resulting in pthread-backend (which was only created
107 to fulfill the rules of the programming languages shootout).
108
1094.45 Thu Mar 13 11:55:36 CET 2008
110 - fix a file leaking bug in eg/mhyttpd that would allow
111 downloading of any file (reported by oesi).
112 - fix deadlock bug in Coro::Channel (reported by Richard Hundt)
113 (also add testcase).
114 - support Broadcast option in Coro::Socket (patch by Richard Hundt,
115 apparently having loads of fun with that).
116 - implement $state->swap_defsv, ->swap_defav and document ->throw.
117
1184.4 Wed Feb 13 16:44:29 CET 2008
119 - only assume .cfi pseudo isns exist on GNU/Linux.
120 - add get_timed method to Coro::Channels.
121 - fixed Coro::Debug manpage.
122 - perl 5.11 compatbility improvement based on patch by
123 Andreas König.
124
1254.37 Sun Jan 20 11:25:23 CET 2008
126 - soften the check for an active parser for perl 5.10 (avoiding
127 "Coro::State::transfer called while parsing" in many cases).
128
1294.36 Sun Jan 13 10:53:56 CET 2008
130 - reset diehook when terminating from an async_pool as to not
131 trigger any __DIE__ handlers.
132
1334.35 Sun Jan 13 04:14:13 CET 2008
134 - "bt" debug command now displays any exceptions
135 from longmess and also skips the innermost
136 stackframes, giving more useufl output.
137 - allow backtraces in coroutines blocked in Coro::EV,
138 at a <1% speed hit.
139 - handle localising of $SIG{__WARN__} and __DIE__
140 properly (with a proper amount of dirty hacking).
141
1424.34 Sat Dec 22 17:49:53 CET 2007
143 - upgrade to EV version 2.0 API.
144
1454.33 Mon Dec 17 08:36:12 CET 2007
146 - make Coro::AIO etc. loadable in the absence of EV.
147
1484.32 Mon Dec 17 07:46:02 CET 2007
149 - majorly improved Coro::Handle's performance with Coro::EV.
150 - implemented the until now mythical Coro::BDB module.
151 - specialcase EV in Coro::AIO and Coro::BDB for extra speed.
152
1534.31 Wed Dec 5 12:32:39 CET 2007
154 - remove warn statement form Coro::Util.
155
1564.3 Tue Dec 4 20:33:14 CET 2007
157 - calls to the idle function could cause stack corruption
158 when the stack changed.
159 - do no longer rely on the presence of EV::DNS if EV is used
160 (because it is gone), but instead take avdantage of EV::ADNS
161 if available.
162 - add ($) prototypes to all functions in Coro::Storable.
163 - use a conventional (safer) idle callback in Coro::EV.
164 - do accept quickly in Coro::Debug to avoid endless loops.
165
1664.22 Fri Nov 30 16:04:04 CET 2007
167 - really use optimised versions for Event and EV in Coro::Util
168 and Coro::Handle.
169
1704.21 Sun Nov 25 10:48:59 CET 2007
171 - fix a spurious memory read.
172 - Coro::EV no longer keeps the eventloop "alive".
173
1744.2 Fri Nov 9 20:47:05 CET 2007
175 - enable/disable tracing from a new coroutine, not a pooled one.
176 - fix a memleak in Coro::Event.
177 - removed killall call from fork_eval.
178 - made sure store_fd is already loaded so that fork_eval
179 does not have to parse autoload in each subprocess.
180 - only use assembly method if -O switch is in $Config{optimize}.
181 - add (optional) Coro::EV module, so far the best event loop module
182 directly supported by Coro.
183 - if the event model is EV, use EV::DNS to resolve
184 stuff in Coro::Util.
185 - don't get confused by multiple event notifications in Coro::Handle.
186 - initial support for EV (libevent interface).
187 - require Event and EV using configure_requires, to force their existance.
188
1894.13 Wed Oct 24 07:26:45 CEST 2007
190 - add Coro::Storable::blocking_thaw.
191 - use a vastly more complicated technique to localise
192 $SIG{__WARN/DIE__} that also works on perls <= 5.8.8.
193 - use a coroutine for the idle callback Coro::Event,
194 instead of running Event in the current coroutine context.
195 This also catches recursive invocations.
196 - actually report fork errors in gethostbyname and inet_aton.
197
1984.11 Thu Oct 11 02:40:24 CEST 2007
199 - port to threaded perls.
200
2014.1 Thu Oct 11 02:38:16 CEST 2007
202 - incompatible change: $SIG{__DIE__} and $SIG{__WARN__} will now
203 be local to each coro (see Coro::State).
204 - incompatible change: for very deep reasons, cede and cede_notself
205 cannot return anything, so nothing will be returned.
206 - possibly bring back 5.10 compatibility (untested).
207 - work around stupid (and wrong) warning on 5.10 :(.
208 - overlay the saved state over the context stack. This saves
209 a few hundred bytes per coroutine on average and also
210 speeds up context switching a bit.
211 - further tune default stack sizes.
212 - (more) correctly calculate stack usage in coro_rss.
213 - Coro::Storable::blocking_* did not properly lock
214 resulting in races between coroutines.
215 - added Coro::Storable::guard.
216 - stopping to trace a coroutine could destroy the cctx of
217 an unrelated coroutine.
218 - explain the relationship between Perl and C coroutines in
219 more detail in Coro::State.
220 - Coro::Util::inet_aton did not short-circuit dotted quad forms,
221 causing a fork per resolve. This also affected Coro::Socket.
222 - switch to a separate stack in $coro->call/eval to avoid
223 invalidating pointers.
224
2254.03 Sat Oct 6 21:24:00 CEST 2007
226 - added Coro::throw method.
227 - minor code cleanups.
228
2294.02 Sat Oct 6 02:36:47 CEST 2007
230 - fix a very minor per-coroutine memleak (a single codereference).
231 - fixed a bug where the currently in-use c context would be freed
232 prematurely (can happen only when programs change the stacksize
233 or use tracing).
234 - tracing can no longer keep a coro alive after it terminated.
235 - do static branch prediction in the common path for gcc. gives
236 about 2-5% speed improvement here.
237
2384.01 Fri Oct 5 22:10:49 CEST 2007
239 - instead of recreating *a* standard output handle we simply
240 use STDOUT, which is faster and hopefully more robust.
241
2424.0 Fri Oct 5 12:56:00 CEST 2007
9 - incompatibly changed Coro::Storable::freeze. 243 - incompatibly changed Coro::Storable::freeze.
