84.1 85.0
9 - (libcoro) did not preserve rbp with CORO_ASM (we are getting there).
10 - (libcoro) no longer leak threads in the experimental pthread backend,
11 also speed it up considerably.
12 - (libcoro) do not rely on makecontext passing void *'s unscathed.
13 - fix compiletime dependencies on libcoro in the Makefile.
14 - cctx_count wasn't always updated properly.
15 - Coro::State::cctx_stacksize wasn't applied correctly.
16 - new function Coro::State::cctx_max_idle.
17 - the default max number of idle C contexts is now 4.
18 - (libcoro) try harder to get _setjmp/_longjmp.
19 - (libcoro) cleanup and extend the libcoro API to officially
20 allow the creation of empty source contexts.
21
224.804 Wed Nov 5 16:36:00 CET 2008
23 - Coro::Debug::new_unix_server would not create a non-blocking listening
24 socket, sometimes causing freezes.
25 - (libcoro) fix misaligned stack points for setjmp and assembly
26 methods, which can cause crashes on x86/x86_64 with a sufficiently
27 aggressive compiler.
28 - new function: Coro::Debug::new_tcp_server.
29 - move ->throw into the Coro class because it only works on coro objects.
30
314.803 Mon Nov 3 17:16:12 CET 2008
32 - (libcoro) use a global asm statement to become independent of gcc
33 otpimisations for CORO_ASM (thanks to pippijn for the idea).
34 - try to workaround yet another broken bsd, this time dragonfly.
35
364.802 Thu Oct 30 10:56:12 CET 2008
37 - support -fno-omit-frame-pointer on x86 with the assembly method.
38 - tune 01_unblock.t tests a bit.
39
404.801 Wed Oct 22 18:33:37 CEST 2008
41 - improve readline speed for very long "lines".
42 - backport to 5.8.8.
43
444.8 Thu Oct 2 13:34:40 CEST 2008
45 - new function Coro::AIO::aio_wait.
46 - Coro.:AIO and Coro::BDB now "use Coro::AnyEvent".
47 - greatly speed up and reduce memory usage of Coro::AIO requests.
48 - implement some other µ-optimisations.
49
504.749 Mon Sep 29 14:40:12 CEST 2008
51 - port to slow and broken pseudo-threaded perls. (courtesy pippijn).
52
534.748 Sat Sep 27 14:03:19 CEST 2008
54 - implement, but do not document, PerlIO::cede(granularity).
55 - Coro::Storable forgot to wrap Storable::pstore.
56 - work around the multitude of leaks and memory corruption
57 bugs in PerlIO::via by using our own C-level perliol. As a side
58 effect, Coro::Storable is now much, much, much faster.
59
604.747 Tue Sep 23 01:59:41 CEST 2008
61 - fix a per-cv memleak (one empty array was leaked per
62 code reference).
63 - avoid a crash in coro->call|rss when the coroutine was already
64 destroyed (most noticably when using Coro::Debug::ps :)
65 - also protect *Storable::FILE.
66 - push up default storable granularity to 20ms.
67
684.746 Sun Sep 21 03:22:20 CEST 2008
69 - be more insistent on locking Storable against reentrancy
70 in Coro::Storable.
71 - move swap_def?v and throw to Coro::State, as documented.
72
734.745 Thu Jul 24 00:14:38 CEST 2008
74 - remove debugging code related to MgPV_nolen_const, also try to
75 make it compile with perl 5.8.6 (yes, apple apparently loves
76 outdated software). Reported by John S.
77
784.744 Tue Jul 8 22:06:35 CEST 2008
79 - correctly provide default DIE/WARN handlers as documented.
80 - also overwrite PL_vtbl_sigelem.svt_clear, even though current
81 implementations inside perl work fine for us.
82
834.743 Mon Jun 16 00:21:57 CEST 2008
84 - when using Coro::EV without running EV::loop it could
85 result in busy-waiting for events, this has been fixed.
86 - reduce codesize and improve performance by using EV_DEFAULT_UC.
87
884.742 Sat May 31 14:10:21 CEST 2008
89 - implement a workaround for (some) perl <5.8.8 versions.
90 - require EV 3.3+.
91
924.741 Fri May 30 23:33:09 CEST 2008
93 - tell netbsd how utterly broken their imitation of an OS is
94 and refuse to build by default if pthreads are in use.
95 - switch to "s" method on all bsd's by default, as their ucontext
96 stuff seems just too broken.
97 - fix a bug in Coro::Select.
98
994.74 Thu May 29 20:05:31 CEST 2008
100 - do not test Coro::LWP for lack of dependencies.
101 - do not test Coro::Select for lack of working perls.
102
1034.73 Thu May 29 2008
104 - fix a bug in Coro::EV which would cause it to block despite
105 there being runnable coroutines.
106 - sprinkle "no warnings" freely over everything, also suppress
107 warnings for some other modules.
108 - fix typo in WSAEWOULDBLOCK.
109
1104.72 Sun May 25 05:14:36 CEST 2008
111 - tweak META.yaml a bit, unfortunately, there is no documented way
112 to have optional dependencies with CPAN. doh :(
113 - avoid running some tests on windows because they would fail due to
114 perl bug (broken fork, broken pipes...).
115 - work around perl on windows bugs where perl returns undocumented
116 error codes for sysread, syswrite etc. by taking advantage
117 of AnyEvent's workaround for that problem.
118 - use AnyEvent::Util::fh_nonblocking in Coro::Handle to work around
119 a common perl implementation bug on windows.
120 - use unix domain sockets in testsuite to work around
121 common perl implementation bugs on widows (they are emulated by
122 tcp sockets on windows. ugh.)
123
1244.71 Sat May 24 20:01:27 CEST 2008
125 - fix a bug in Coro::AnyEvent ("Usage: Coro::AnyEvent::_schedule()").
126 - take advantage of async name resolution of AnyEvent::Util.
127 - work around brutal inet_aton override in Coro::LWP.
128 - take advantage of the readyhook in Coro::EV, for smoother
129 scheduling.
130
1314.7 Sun May 11 00:32:19 CEST 2008
132 - completely reworked the Coro manpage.
133 - added Coro::AnyEvent, generic event loop integration.
134 - implement cancel, ready and kill commands in Coro::Debug.
135 - document find_coro in Coro::Debug.
136 - incompatible change: rename has_stack to has_cctx.
137 - Coro::AIO and Coro::BDB no longer force event model detection,
138 use AnyEvent::AIO and AnyEvent::BDB.
139
1404.6 Sat Apr 26 10:05:14 CEST 2008
141 - INCOMPATIBLE CHANGE: sub/code attributes are no longer supported
142 by the Coro module. It was a mistake to have it in the first place.
143 - (experimental) support for activestate perl 5.10 (method "w").
144 - (experimental) support for strawberry perl (method "a").
145 - coro_sigelem_set did not return a value although it had to,
146 actual impact unknown.
147
1484.51 Mon Apr 14 13:28:27 CEST 2008
149 - make it compile again on 5.8.
150
1514.50 Thu Apr 10 09:43:17 CEST 2008
152 - I did it twice! (see 4.49).
153
1544.49 Sun Apr 6 21:23:31 CEST 2008
155 - grr, instead of compiling the recent changes on 5.10 only they
156 were compiled on 5.8 only.
157
1584.48 Sun Apr 6 20:36:46 CEST 2008
159 - allow coroutine switches during eval's under 5.10.x, as it seems
160 the parser is a per-interpreter option now, so this is safe
161 (this might fix the odd crashing bug).
162 - drop support for 5.9.x versions: they are dead, jim.
163
1644.47 Sun Apr 6 00:37:52 CEST 2008
165 - force cctx allocation on API calls: we know we need to force one
166 and gcc actually manages to confuse our heuristic nowadays,
167 leading to crashes and worse.
168 - document force_cctx.
169
1704.46 Fri Apr 4 22:05:43 CEST 2008
171 - upgrade libcoro, resulting in pthread-backend (which was only created
172 to fulfill the rules of the programming languages shootout).
173
1744.45 Thu Mar 13 11:55:36 CET 2008
175 - fix a file leaking bug in eg/mhyttpd that would allow
176 downloading of any file (reported by oesi).
177 - fix deadlock bug in Coro::Channel (reported by Richard Hundt)
178 (also add testcase).
179 - support Broadcast option in Coro::Socket (patch by Richard Hundt,
180 apparently having loads of fun with that).
181 - implement $state->swap_defsv, ->swap_defav and document ->throw.
182
1834.4 Wed Feb 13 16:44:29 CET 2008
184 - only assume .cfi pseudo isns exist on GNU/Linux.
185 - add get_timed method to Coro::Channels.
186 - fixed Coro::Debug manpage.
187 - perl 5.11 compatbility improvement based on patch by
188 Andreas König.
189
1904.37 Sun Jan 20 11:25:23 CET 2008
191 - soften the check for an active parser for perl 5.10 (avoiding
192 "Coro::State::transfer called while parsing" in many cases).
193
1944.36 Sun Jan 13 10:53:56 CET 2008
195 - reset diehook when terminating from an async_pool as to not
196 trigger any __DIE__ handlers.
197
1984.35 Sun Jan 13 04:14:13 CET 2008
199 - "bt" debug command now displays any exceptions
200 from longmess and also skips the innermost
201 stackframes, giving more useufl output.
202 - allow backtraces in coroutines blocked in Coro::EV,
203 at a <1% speed hit.
204 - handle localising of $SIG{__WARN__} and __DIE__
205 properly (with a proper amount of dirty hacking).
206
2074.34 Sat Dec 22 17:49:53 CET 2007
208 - upgrade to EV version 2.0 API.
209
2104.33 Mon Dec 17 08:36:12 CET 2007
211 - make Coro::AIO etc. loadable in the absence of EV.
212
2134.32 Mon Dec 17 07:46:02 CET 2007
214 - majorly improved Coro::Handle's performance with Coro::EV.
215 - implemented the until now mythical Coro::BDB module.
216 - specialcase EV in Coro::AIO and Coro::BDB for extra speed.
217
2184.31 Wed Dec 5 12:32:39 CET 2007
219 - remove warn statement form Coro::Util.
220
2214.3 Tue Dec 4 20:33:14 CET 2007
222 - calls to the idle function could cause stack corruption
223 when the stack changed.
224 - do no longer rely on the presence of EV::DNS if EV is used
225 (because it is gone), but instead take avdantage of EV::ADNS
226 if available.
227 - add ($) prototypes to all functions in Coro::Storable.
228 - use a conventional (safer) idle callback in Coro::EV.
229 - do accept quickly in Coro::Debug to avoid endless loops.
230
2314.22 Fri Nov 30 16:04:04 CET 2007
232 - really use optimised versions for Event and EV in Coro::Util
233 and Coro::Handle.
234
2354.21 Sun Nov 25 10:48:59 CET 2007
236 - fix a spurious memory read.
237 - Coro::EV no longer keeps the eventloop "alive".
238
2394.2 Fri Nov 9 20:47:05 CET 2007
240 - enable/disable tracing from a new coroutine, not a pooled one.
241 - fix a memleak in Coro::Event.
242 - removed killall call from fork_eval.
243 - made sure store_fd is already loaded so that fork_eval
244 does not have to parse autoload in each subprocess.
245 - only use assembly method if -O switch is in $Config{optimize}.
246 - add (optional) Coro::EV module, so far the best event loop module
247 directly supported by Coro.
248 - if the event model is EV, use EV::DNS to resolve
249 stuff in Coro::Util.
250 - don't get confused by multiple event notifications in Coro::Handle.
251 - initial support for EV (libevent interface).
252 - require Event and EV using configure_requires, to force their existance.
253
2544.13 Wed Oct 24 07:26:45 CEST 2007
255 - add Coro::Storable::blocking_thaw.
256 - use a vastly more complicated technique to localise
257 $SIG{__WARN/DIE__} that also works on perls <= 5.8.8.
258 - use a coroutine for the idle callback Coro::Event,
259 instead of running Event in the current coroutine context.
260 This also catches recursive invocations.
261 - actually report fork errors in gethostbyname and inet_aton.
262
2634.11 Thu Oct 11 02:40:24 CEST 2007
264 - port to threaded perls.
265
2664.1 Thu Oct 11 02:38:16 CEST 2007
9 - incompatible change: $SIG{__DIE__} and $SIG{__WARN__} will now 267 - incompatible change: $SIG{__DIE__} and $SIG{__WARN__} will now
10 be local to each coro (see Coro::State). 268 be local to each coro (see Coro::State).
269 - incompatible change: for very deep reasons, cede and cede_notself
270 cannot return anything, so nothing will be returned.
11 - possibly bring back 5.10 compatibility (untested). 271 - possibly bring back 5.10 compatibility (untested).
12 - work around stupid (and wrong) warning on 5.10 :(. 272 - work around stupid (and wrong) warning on 5.10 :(.
13 - overlay the saved state over the context stack. This saves 273 - overlay the saved state over the context stack. This saves
14 a few hundred bytes per coroutine on average and also 274 a few hundred bytes per coroutine on average and also
15 speeds up context switching a bit. 275 speeds up context switching a bit.
… …
20 - added Coro::Storable::guard. 280 - added Coro::Storable::guard.
21 - stopping to trace a coroutine could destroy the cctx of 281 - stopping to trace a coroutine could destroy the cctx of
22 an unrelated coroutine. 282 an unrelated coroutine.
23 - explain the relationship between Perl and C coroutines in 283 - explain the relationship between Perl and C coroutines in
24 more detail in Coro::State. 284 more detail in Coro::State.
285 - Coro::Util::inet_aton did not short-circuit dotted quad forms,
286 causing a fork per resolve. This also affected Coro::Socket.
287 - switch to a separate stack in $coro->call/eval to avoid
288 invalidating pointers.
25 289
264.03 Sat Oct 6 21:24:00 CEST 2007 2904.03 Sat Oct 6 21:24:00 CEST 2007
