7 7
84.1 8 - move ->throw into the Coro class because it only works on coro objects.
9
104.803 Mon Nov 3 17:16:12 CET 2008
11 - use a global asm statement to become independent of gcc otpimisations
12 for CORO_ASM (thanks to pippijn for the idea).
13 - try to workaround yet another broken bsd, this time dragonfly.
14
154.802 Thu Oct 30 10:56:12 CET 2008
16 - support -fno-omit-frame-pointer on x86 with the assembly method.
17 - tune 01_unblock.t tests a bit.
18
194.801 Wed Oct 22 18:33:37 CEST 2008
20 - improve readline speed for very long "lines".
21 - backport to 5.8.8.
22
234.8 Thu Oct 2 13:34:40 CEST 2008
24 - new function Coro::AIO::aio_wait.
25 - Coro.:AIO and Coro::BDB now "use Coro::AnyEvent".
26 - greatly speed up and reduce memory usage of Coro::AIO requests.
27 - implement some other µ-optimisations.
28
294.749 Mon Sep 29 14:40:12 CEST 2008
30 - port to slow and broken pseudo-threaded perls. (courtesy pippijn).
31
324.748 Sat Sep 27 14:03:19 CEST 2008
33 - implement, but do not document, PerlIO::cede(granularity).
34 - Coro::Storable forgot to wrap Storable::pstore.
35 - work around the multitude of leaks and memory corruption
36 bugs in PerlIO::via by using our own C-level perliol. As a side
37 effect, Coro::Storable is now much, much, much faster.
38
394.747 Tue Sep 23 01:59:41 CEST 2008
40 - fix a per-cv memleak (one empty array was leaked per
41 code reference).
42 - avoid a crash in coro->call|rss when the coroutine was already
43 destroyed (most noticably when using Coro::Debug::ps :)
44 - also protect *Storable::FILE.
45 - push up default storable granularity to 20ms.
46
474.746 Sun Sep 21 03:22:20 CEST 2008
48 - be more insistent on locking Storable against reentrancy
49 in Coro::Storable.
50 - move swap_def?v and throw to Coro::State, as documented.
51
524.745 Thu Jul 24 00:14:38 CEST 2008
53 - remove debugging code related to MgPV_nolen_const, also try to
54 make it compile with perl 5.8.6 (yes, apple apparently loves
55 outdated software). Reported by John S.
56
574.744 Tue Jul 8 22:06:35 CEST 2008
58 - correctly provide default DIE/WARN handlers as documented.
59 - also overwrite PL_vtbl_sigelem.svt_clear, even though current
60 implementations inside perl work fine for us.
61
624.743 Mon Jun 16 00:21:57 CEST 2008
63 - when using Coro::EV without running EV::loop it could
64 result in busy-waiting for events, this has been fixed.
65 - reduce codesize and improve performance by using EV_DEFAULT_UC.
66
674.742 Sat May 31 14:10:21 CEST 2008
68 - implement a workaround for (some) perl <5.8.8 versions.
69 - require EV 3.3+.
70
714.741 Fri May 30 23:33:09 CEST 2008
72 - tell netbsd how utterly broken their imitation of an OS is
73 and refuse to build by default if pthreads are in use.
74 - switch to "s" method on all bsd's by default, as their ucontext
75 stuff seems just too broken.
76 - fix a bug in Coro::Select.
77
784.74 Thu May 29 20:05:31 CEST 2008
79 - do not test Coro::LWP for lack of dependencies.
80 - do not test Coro::Select for lack of working perls.
81
824.73 Thu May 29 2008
83 - fix a bug in Coro::EV which would cause it to block despite
84 there being runnable coroutines.
85 - sprinkle "no warnings" freely over everything, also suppress
86 warnings for some other modules.
87 - fix typo in WSAEWOULDBLOCK.
88
894.72 Sun May 25 05:14:36 CEST 2008
90 - tweak META.yaml a bit, unfortunately, there is no documented way
91 to have optional dependencies with CPAN. doh :(
92 - avoid running some tests on windows because they would fail due to
93 perl bug (broken fork, broken pipes...).
94 - work around perl on windows bugs where perl returns undocumented
95 error codes for sysread, syswrite etc. by taking advantage
96 of AnyEvent's workaround for that problem.
97 - use AnyEvent::Util::fh_nonblocking in Coro::Handle to work around
98 a common perl implementation bug on windows.
99 - use unix domain sockets in testsuite to work around
100 common perl implementation bugs on widows (they are emulated by
101 tcp sockets on windows. ugh.)
102
1034.71 Sat May 24 20:01:27 CEST 2008
104 - fix a bug in Coro::AnyEvent ("Usage: Coro::AnyEvent::_schedule()").
105 - take advantage of async name resolution of AnyEvent::Util.
106 - work around brutal inet_aton override in Coro::LWP.
107 - take advantage of the readyhook in Coro::EV, for smoother
108 scheduling.
109
1104.7 Sun May 11 00:32:19 CEST 2008
111 - completely reworked the Coro manpage.
112 - added Coro::AnyEvent, generic event loop integration.
113 - implement cancel, ready and kill commands in Coro::Debug.
114 - document find_coro in Coro::Debug.
115 - incompatible change: rename has_stack to has_cctx.
116 - Coro::AIO and Coro::BDB no longer force event model detection,
117 use AnyEvent::AIO and AnyEvent::BDB.
118
1194.6 Sat Apr 26 10:05:14 CEST 2008
120 - INCOMPATIBLE CHANGE: sub/code attributes are no longer supported
121 by the Coro module. It was a mistake to have it in the first place.
122 - (experimental) support for activestate perl 5.10 (method "w").
123 - (experimental) support for strawberry perl (method "a").
124 - coro_sigelem_set did not return a value although it had to,
125 actual impact unknown.
126
1274.51 Mon Apr 14 13:28:27 CEST 2008
128 - make it compile again on 5.8.
129
1304.50 Thu Apr 10 09:43:17 CEST 2008
131 - I did it twice! (see 4.49).
132
1334.49 Sun Apr 6 21:23:31 CEST 2008
134 - grr, instead of compiling the recent changes on 5.10 only they
135 were compiled on 5.8 only.
136
1374.48 Sun Apr 6 20:36:46 CEST 2008
138 - allow coroutine switches during eval's under 5.10.x, as it seems
139 the parser is a per-interpreter option now, so this is safe
140 (this might fix the odd crashing bug).
141 - drop support for 5.9.x versions: they are dead, jim.
142
1434.47 Sun Apr 6 00:37:52 CEST 2008
144 - force cctx allocation on API calls: we know we need to force one
145 and gcc actually manages to confuse our heuristic nowadays,
146 leading to crashes and worse.
147 - document force_cctx.
148
1494.46 Fri Apr 4 22:05:43 CEST 2008
150 - upgrade libcoro, resulting in pthread-backend (which was only created
151 to fulfill the rules of the programming languages shootout).
152
1534.45 Thu Mar 13 11:55:36 CET 2008
154 - fix a file leaking bug in eg/mhyttpd that would allow
155 downloading of any file (reported by oesi).
156 - fix deadlock bug in Coro::Channel (reported by Richard Hundt)
157 (also add testcase).
158 - support Broadcast option in Coro::Socket (patch by Richard Hundt,
159 apparently having loads of fun with that).
160 - implement $state->swap_defsv, ->swap_defav and document ->throw.
161
1624.4 Wed Feb 13 16:44:29 CET 2008
163 - only assume .cfi pseudo isns exist on GNU/Linux.
164 - add get_timed method to Coro::Channels.
165 - fixed Coro::Debug manpage.
166 - perl 5.11 compatbility improvement based on patch by
167 Andreas König.
168
1694.37 Sun Jan 20 11:25:23 CET 2008
170 - soften the check for an active parser for perl 5.10 (avoiding
171 "Coro::State::transfer called while parsing" in many cases).
172
1734.36 Sun Jan 13 10:53:56 CET 2008
174 - reset diehook when terminating from an async_pool as to not
175 trigger any __DIE__ handlers.
176
1774.35 Sun Jan 13 04:14:13 CET 2008
178 - "bt" debug command now displays any exceptions
179 from longmess and also skips the innermost
180 stackframes, giving more useufl output.
181 - allow backtraces in coroutines blocked in Coro::EV,
182 at a <1% speed hit.
183 - handle localising of $SIG{__WARN__} and __DIE__
184 properly (with a proper amount of dirty hacking).
185
1864.34 Sat Dec 22 17:49:53 CET 2007
187 - upgrade to EV version 2.0 API.
188
1894.33 Mon Dec 17 08:36:12 CET 2007
190 - make Coro::AIO etc. loadable in the absence of EV.
191
1924.32 Mon Dec 17 07:46:02 CET 2007
193 - majorly improved Coro::Handle's performance with Coro::EV.
194 - implemented the until now mythical Coro::BDB module.
195 - specialcase EV in Coro::AIO and Coro::BDB for extra speed.
196
1974.31 Wed Dec 5 12:32:39 CET 2007
198 - remove warn statement form Coro::Util.
199
2004.3 Tue Dec 4 20:33:14 CET 2007
201 - calls to the idle function could cause stack corruption
202 when the stack changed.
203 - do no longer rely on the presence of EV::DNS if EV is used
204 (because it is gone), but instead take avdantage of EV::ADNS
205 if available.
206 - add ($) prototypes to all functions in Coro::Storable.
207 - use a conventional (safer) idle callback in Coro::EV.
208 - do accept quickly in Coro::Debug to avoid endless loops.
209
2104.22 Fri Nov 30 16:04:04 CET 2007
211 - really use optimised versions for Event and EV in Coro::Util
212 and Coro::Handle.
213
2144.21 Sun Nov 25 10:48:59 CET 2007
215 - fix a spurious memory read.
216 - Coro::EV no longer keeps the eventloop "alive".
217
2184.2 Fri Nov 9 20:47:05 CET 2007
219 - enable/disable tracing from a new coroutine, not a pooled one.
220 - fix a memleak in Coro::Event.
221 - removed killall call from fork_eval.
222 - made sure store_fd is already loaded so that fork_eval
223 does not have to parse autoload in each subprocess.
224 - only use assembly method if -O switch is in $Config{optimize}.
225 - add (optional) Coro::EV module, so far the best event loop module
226 directly supported by Coro.
227 - if the event model is EV, use EV::DNS to resolve
228 stuff in Coro::Util.
229 - don't get confused by multiple event notifications in Coro::Handle.
230 - initial support for EV (libevent interface).
231 - require Event and EV using configure_requires, to force their existance.
232
2334.13 Wed Oct 24 07:26:45 CEST 2007
234 - add Coro::Storable::blocking_thaw.
235 - use a vastly more complicated technique to localise
236 $SIG{__WARN/DIE__} that also works on perls <= 5.8.8.
237 - use a coroutine for the idle callback Coro::Event,
238 instead of running Event in the current coroutine context.
239 This also catches recursive invocations.
240 - actually report fork errors in gethostbyname and inet_aton.
241
2424.11 Thu Oct 11 02:40:24 CEST 2007
243 - port to threaded perls.
244
2454.1 Thu Oct 11 02:38:16 CEST 2007
9 - incompatible change: $SIG{__DIE__} and $SIG{__WARN__} will now 246 - incompatible change: $SIG{__DIE__} and $SIG{__WARN__} will now
10 be local to each coro (see Coro::State). 247 be local to each coro (see Coro::State).
248 - incompatible change: for very deep reasons, cede and cede_notself
249 cannot return anything, so nothing will be returned.
11 - possibly bring back 5.10 compatibility (untested). 250 - possibly bring back 5.10 compatibility (untested).
12 - work around stupid (and wrong) warning on 5.10 :(. 251 - work around stupid (and wrong) warning on 5.10 :(.
13 - overlay the saved state over the context stack. This saves 252 - overlay the saved state over the context stack. This saves
14 a few hundred bytes per coroutine on average and also 253 a few hundred bytes per coroutine on average and also
15 speeds up context switching a bit. 254 speeds up context switching a bit.

23 - explain the relationship between Perl and C coroutines in 262 - explain the relationship between Perl and C coroutines in
24 more detail in Coro::State. 263 more detail in Coro::State.
25 - Coro::Util::inet_aton did not short-circuit dotted quad forms, 264 - Coro::Util::inet_aton did not short-circuit dotted quad forms,
26 causing a fork per resolve. This also affected Coro::Socket. 265 causing a fork per resolve. This also affected Coro::Socket.
27 - sped up Coro::Event next event handling by 15%, uses less memory.
