84.1 84.801 Wed Oct 22 18:33:37 CEST 2008
9 - improve readline speed for very long "lines".
10 - backport to 5.8.8.
11
124.8 Thu Oct 2 13:34:40 CEST 2008
13 - new function Coro::AIO::aio_wait.
14 - Coro.:AIO and Coro::BDB now "use Coro::AnyEvent".
15 - greatly speed up and reduce memory usage of Coro::AIO requests.
16 - implement some other µ-optimisations.
17
184.749 Mon Sep 29 14:40:12 CEST 2008
19 - port to slow and broken pseudo-threaded perls. (courtesy pippijn).
20
214.748 Sat Sep 27 14:03:19 CEST 2008
22 - implement, but do not document, PerlIO::cede(granularity).
23 - Coro::Storable forgot to wrap Storable::pstore.
24 - work around the multitude of leaks and memory corruption
25 bugs in PerlIO::via by using our own C-level perliol. As a side
26 effect, Coro::Storable is now much, much, much faster.
27
284.747 Tue Sep 23 01:59:41 CEST 2008
29 - fix a per-cv memleak (one empty array was leaked per
30 code reference).
31 - avoid a crash in coro->call|rss when the coroutine was already
32 destroyed (most noticably when using Coro::Debug::ps :)
33 - also protect *Storable::FILE.
34 - push up default storable granularity to 20ms.
35
364.746 Sun Sep 21 03:22:20 CEST 2008
37 - be more insistent on locking Storable against reentrancy
38 in Coro::Storable.
39 - move swap_def?v and throw to Coro::State, as documented.
40
414.745 Thu Jul 24 00:14:38 CEST 2008
42 - remove debugging code related to MgPV_nolen_const, also try to
43 make it compile with perl 5.8.6 (yes, apple apparently loves
44 outdated software). Reported by John S.
45
464.744 Tue Jul 8 22:06:35 CEST 2008
47 - correctly provide default DIE/WARN handlers as documented.
48 - also overwrite PL_vtbl_sigelem.svt_clear, even though current
49 implementations inside perl work fine for us.
50
514.743 Mon Jun 16 00:21:57 CEST 2008
52 - when using Coro::EV without running EV::loop it could
53 result in busy-waiting for events, this has been fixed.
54 - reduce codesize and improve performance by using EV_DEFAULT_UC.
55
564.742 Sat May 31 14:10:21 CEST 2008
57 - implement a workaround for (some) perl <5.8.8 versions.
58 - require EV 3.3+.
59
604.741 Fri May 30 23:33:09 CEST 2008
61 - tell netbsd how utterly broken their imitation of an OS is
62 and refuse to build by default if pthreads are in use.
63 - switch to "s" method on all bsd's by default, as their ucontext
64 stuff seems just too broken.
65 - fix a bug in Coro::Select.
66
674.74 Thu May 29 20:05:31 CEST 2008
68 - do not test Coro::LWP for lack of dependencies.
69 - do not test Coro::Select for lack of working perls.
70
714.73 Thu May 29 2008
72 - fix a bug in Coro::EV which would cause it to block despite
73 there being runnable coroutines.
74 - sprinkle "no warnings" freely over everything, also suppress
75 warnings for some other modules.
76 - fix typo in WSAEWOULDBLOCK.
77
784.72 Sun May 25 05:14:36 CEST 2008
79 - tweak META.yaml a bit, unfortunately, there is no documented way
80 to have optional dependencies with CPAN. doh :(
81 - avoid running some tests on windows because they would fail due to
82 perl bug (broken fork, broken pipes...).
83 - work around perl on windows bugs where perl returns undocumented
84 error codes for sysread, syswrite etc. by taking advantage
85 of AnyEvent's workaround for that problem.
86 - use AnyEvent::Util::fh_nonblocking in Coro::Handle to work around
87 a common perl implementation bug on windows.
88 - use unix domain sockets in testsuite to work around
89 common perl implementation bugs on widows (they are emulated by
90 tcp sockets on windows. ugh.)
91
924.71 Sat May 24 20:01:27 CEST 2008
93 - fix a bug in Coro::AnyEvent ("Usage: Coro::AnyEvent::_schedule()").
94 - take advantage of async name resolution of AnyEvent::Util.
95 - work around brutal inet_aton override in Coro::LWP.
96 - take advantage of the readyhook in Coro::EV, for smoother
97 scheduling.
98
994.7 Sun May 11 00:32:19 CEST 2008
100 - completely reworked the Coro manpage.
101 - added Coro::AnyEvent, generic event loop integration.
102 - implement cancel, ready and kill commands in Coro::Debug.
103 - document find_coro in Coro::Debug.
104 - incompatible change: rename has_stack to has_cctx.
105 - Coro::AIO and Coro::BDB no longer force event model detection,
106 use AnyEvent::AIO and AnyEvent::BDB.
107
1084.6 Sat Apr 26 10:05:14 CEST 2008
109 - INCOMPATIBLE CHANGE: sub/code attributes are no longer supported
110 by the Coro module. It was a mistake to have it in the first place.
111 - (experimental) support for activestate perl 5.10 (method "w").
112 - (experimental) support for strawberry perl (method "a").
113 - coro_sigelem_set did not return a value although it had to,
114 actual impact unknown.
115
1164.51 Mon Apr 14 13:28:27 CEST 2008
117 - make it compile again on 5.8.
118
1194.50 Thu Apr 10 09:43:17 CEST 2008
120 - I did it twice! (see 4.49).
121
1224.49 Sun Apr 6 21:23:31 CEST 2008
123 - grr, instead of compiling the recent changes on 5.10 only they
124 were compiled on 5.8 only.
125
1264.48 Sun Apr 6 20:36:46 CEST 2008
127 - allow coroutine switches during eval's under 5.10.x, as it seems
128 the parser is a per-interpreter option now, so this is safe
129 (this might fix the odd crashing bug).
130 - drop support for 5.9.x versions: they are dead, jim.
131
1324.47 Sun Apr 6 00:37:52 CEST 2008
133 - force cctx allocation on API calls: we know we need to force one
134 and gcc actually manages to confuse our heuristic nowadays,
135 leading to crashes and worse.
136 - document force_cctx.
137
1384.46 Fri Apr 4 22:05:43 CEST 2008
139 - upgrade libcoro, resulting in pthread-backend (which was only created
140 to fulfill the rules of the programming languages shootout).
141
1424.45 Thu Mar 13 11:55:36 CET 2008
143 - fix a file leaking bug in eg/mhyttpd that would allow
144 downloading of any file (reported by oesi).
145 - fix deadlock bug in Coro::Channel (reported by Richard Hundt)
146 (also add testcase).
147 - support Broadcast option in Coro::Socket (patch by Richard Hundt,
148 apparently having loads of fun with that).
149 - implement $state->swap_defsv, ->swap_defav and document ->throw.
150
1514.4 Wed Feb 13 16:44:29 CET 2008
152 - only assume .cfi pseudo isns exist on GNU/Linux.
153 - add get_timed method to Coro::Channels.
154 - fixed Coro::Debug manpage.
155 - perl 5.11 compatbility improvement based on patch by
156 Andreas König.
157
1584.37 Sun Jan 20 11:25:23 CET 2008
159 - soften the check for an active parser for perl 5.10 (avoiding
160 "Coro::State::transfer called while parsing" in many cases).
161
1624.36 Sun Jan 13 10:53:56 CET 2008
163 - reset diehook when terminating from an async_pool as to not
164 trigger any __DIE__ handlers.
165
1664.35 Sun Jan 13 04:14:13 CET 2008
167 - "bt" debug command now displays any exceptions
168 from longmess and also skips the innermost
169 stackframes, giving more useufl output.
170 - allow backtraces in coroutines blocked in Coro::EV,
171 at a <1% speed hit.
172 - handle localising of $SIG{__WARN__} and __DIE__
173 properly (with a proper amount of dirty hacking).
174
1754.34 Sat Dec 22 17:49:53 CET 2007
176 - upgrade to EV version 2.0 API.
177
1784.33 Mon Dec 17 08:36:12 CET 2007
179 - make Coro::AIO etc. loadable in the absence of EV.
180
1814.32 Mon Dec 17 07:46:02 CET 2007
182 - majorly improved Coro::Handle's performance with Coro::EV.
183 - implemented the until now mythical Coro::BDB module.
184 - specialcase EV in Coro::AIO and Coro::BDB for extra speed.
185
1864.31 Wed Dec 5 12:32:39 CET 2007
187 - remove warn statement form Coro::Util.
188
1894.3 Tue Dec 4 20:33:14 CET 2007
190 - calls to the idle function could cause stack corruption
191 when the stack changed.
192 - do no longer rely on the presence of EV::DNS if EV is used
193 (because it is gone), but instead take avdantage of EV::ADNS
194 if available.
195 - add ($) prototypes to all functions in Coro::Storable.
196 - use a conventional (safer) idle callback in Coro::EV.
197 - do accept quickly in Coro::Debug to avoid endless loops.
198
1994.22 Fri Nov 30 16:04:04 CET 2007
200 - really use optimised versions for Event and EV in Coro::Util
201 and Coro::Handle.
202
2034.21 Sun Nov 25 10:48:59 CET 2007
204 - fix a spurious memory read.
205 - Coro::EV no longer keeps the eventloop "alive".
206
2074.2 Fri Nov 9 20:47:05 CET 2007
208 - enable/disable tracing from a new coroutine, not a pooled one.
209 - fix a memleak in Coro::Event.
210 - removed killall call from fork_eval.
211 - made sure store_fd is already loaded so that fork_eval
212 does not have to parse autoload in each subprocess.
213 - only use assembly method if -O switch is in $Config{optimize}.
214 - add (optional) Coro::EV module, so far the best event loop module
215 directly supported by Coro.
216 - if the event model is EV, use EV::DNS to resolve
217 stuff in Coro::Util.
218 - don't get confused by multiple event notifications in Coro::Handle.
219 - initial support for EV (libevent interface).
220 - require Event and EV using configure_requires, to force their existance.
221
2224.13 Wed Oct 24 07:26:45 CEST 2007
223 - add Coro::Storable::blocking_thaw.
224 - use a vastly more complicated technique to localise
225 $SIG{__WARN/DIE__} that also works on perls <= 5.8.8.
226 - use a coroutine for the idle callback Coro::Event,
227 instead of running Event in the current coroutine context.
228 This also catches recursive invocations.
229 - actually report fork errors in gethostbyname and inet_aton.
230
2314.11 Thu Oct 11 02:40:24 CEST 2007
232 - port to threaded perls.
233
2344.1 Thu Oct 11 02:38:16 CEST 2007
9 - incompatible change: $SIG{__DIE__} and $SIG{__WARN__} will now 235 - incompatible change: $SIG{__DIE__} and $SIG{__WARN__} will now
10 be local to each coro (see Coro::State). 236 be local to each coro (see Coro::State).
237 - incompatible change: for very deep reasons, cede and cede_notself
238 cannot return anything, so nothing will be returned.
11 - possibly bring back 5.10 compatibility (untested). 239 - possibly bring back 5.10 compatibility (untested).
12 - work around stupid (and wrong) warning on 5.10 :(. 240 - work around stupid (and wrong) warning on 5.10 :(.
13 - overlay the saved state over the context stack. This saves 241 - overlay the saved state over the context stack. This saves
14 a few hundred bytes per coroutine on average and also 242 a few hundred bytes per coroutine on average and also
15 speeds up context switching a bit. 243 speeds up context switching a bit.
… …
22 an unrelated coroutine. 250 an unrelated coroutine.
23 - explain the relationship between Perl and C coroutines in 251 - explain the relationship between Perl and C coroutines in
24 more detail in Coro::State. 252 more detail in Coro::State.
25 - Coro::Util::inet_aton did not short-circuit dotted quad forms, 253 - Coro::Util::inet_aton did not short-circuit dotted quad forms,
26 causing a fork per resolve. This also affected Coro::Socket. 254 causing a fork per resolve. This also affected Coro::Socket.
27 - sped up Coro::Event next event handling by 15%, uses less memory. 255 - switch to a separate stack in $coro->call/eval to avoid
256 invalidating pointers.
