1Revision history for Perl extension Coro. 1Revision history for Perl extension Coro.
2 2
3TODO: better (earlier) error messages on broken transfer's 3TODO: should explore PerlIO::via::CoroCede and PerlIO::via::CoroAIO.
4TODO: destroy gets only called on cancel: fix(?) 4TODO: maybe implement a default message channel, very much like Erlang's
5 actor model (which is cool in a lot of important aspects (failures!),
6 but very lacking in others (higher level ipc)).
7
8 - take advantage of async name resolution of AnyEvent::Util.
9 - work around brutal inet_aton override in Coro::LWP.
10
114.7 Sun May 11 00:32:19 CEST 2008
12 - completely reworked the Coro manpage.
13 - added Coro::AnyEvent, generic event loop integration.
14 - implement cancel, ready and kill commands in Coro::Debug.
15 - document find_coro in Coro::Debug.
16 - incompatible change: rename has_stack to has_cctx.
17 - Coro::AIO and Coro::BDB no longer force event model detection,
18 use AnyEvent::AIO and AnyEvent::BDB.
19
204.6 Sat Apr 26 10:05:14 CEST 2008
21 - INCOMPATIBLE CHANGE: sub/code attributes are no longer supported
22 by the Coro module. It was a mistake to have it in the first place.
23 - (experimental) support for activestate perl 5.10 (method "w").
24 - (experimental) support for strawberry perl (method "a").
25 - coro_sigelem_set did not return a value although it had to,
26 actual impact unknown.
27
284.51 Mon Apr 14 13:28:27 CEST 2008
29 - make it compile again on 5.8.
30
314.50 Thu Apr 10 09:43:17 CEST 2008
32 - I did it twice! (see 4.49).
33
344.49 Sun Apr 6 21:23:31 CEST 2008
35 - grr, instead of compiling the recent changes on 5.10 only they
36 were compiled on 5.8 only.
37
384.48 Sun Apr 6 20:36:46 CEST 2008
39 - allow coroutine switches during eval's under 5.10.x, as it seems
40 the parser is a per-interpreter option now, so this is safe
41 (this might fix the odd crashing bug).
42 - drop support for 5.9.x versions: they are dead, jim.
43
444.47 Sun Apr 6 00:37:52 CEST 2008
45 - force cctx allocation on API calls: we know we need to force one
46 and gcc actually manages to confuse our heuristic nowadays,
47 leading to crashes and worse.
48 - document force_cctx.
49
504.46 Fri Apr 4 22:05:43 CEST 2008
51 - upgrade libcoro, resulting in pthread-backend (which was only created
52 to fulfill the rules of the programming languages shootout).
53
544.45 Thu Mar 13 11:55:36 CET 2008
55 - fix a file leaking bug in eg/mhyttpd that would allow
56 downloading of any file (reported by oesi).
57 - fix deadlock bug in Coro::Channel (reported by Richard Hundt)
58 (also add testcase).
59 - support Broadcast option in Coro::Socket (patch by Richard Hundt,
60 apparently having loads of fun with that).
61 - implement $state->swap_defsv, ->swap_defav and document ->throw.
62
634.4 Wed Feb 13 16:44:29 CET 2008
64 - only assume .cfi pseudo isns exist on GNU/Linux.
65 - add get_timed method to Coro::Channels.
66 - fixed Coro::Debug manpage.
67 - perl 5.11 compatbility improvement based on patch by
68 Andreas König.
69
704.37 Sun Jan 20 11:25:23 CET 2008
71 - soften the check for an active parser for perl 5.10 (avoiding
72 "Coro::State::transfer called while parsing" in many cases).
73
744.36 Sun Jan 13 10:53:56 CET 2008
75 - reset diehook when terminating from an async_pool as to not
76 trigger any __DIE__ handlers.
77
784.35 Sun Jan 13 04:14:13 CET 2008
79 - "bt" debug command now displays any exceptions
80 from longmess and also skips the innermost
81 stackframes, giving more useufl output.
82 - allow backtraces in coroutines blocked in Coro::EV,
83 at a <1% speed hit.
84 - handle localising of $SIG{__WARN__} and __DIE__
85 properly (with a proper amount of dirty hacking).
86
874.34 Sat Dec 22 17:49:53 CET 2007
88 - upgrade to EV version 2.0 API.
89
904.33 Mon Dec 17 08:36:12 CET 2007
91 - make Coro::AIO etc. loadable in the absence of EV.
92
934.32 Mon Dec 17 07:46:02 CET 2007
94 - majorly improved Coro::Handle's performance with Coro::EV.
95 - implemented the until now mythical Coro::BDB module.
96 - specialcase EV in Coro::AIO and Coro::BDB for extra speed.
97
984.31 Wed Dec 5 12:32:39 CET 2007
99 - remove warn statement form Coro::Util.
100
1014.3 Tue Dec 4 20:33:14 CET 2007
102 - calls to the idle function could cause stack corruption
103 when the stack changed.
104 - do no longer rely on the presence of EV::DNS if EV is used
105 (because it is gone), but instead take avdantage of EV::ADNS
106 if available.
107 - add ($) prototypes to all functions in Coro::Storable.
108 - use a conventional (safer) idle callback in Coro::EV.
109 - do accept quickly in Coro::Debug to avoid endless loops.
110
1114.22 Fri Nov 30 16:04:04 CET 2007
112 - really use optimised versions for Event and EV in Coro::Util
113 and Coro::Handle.
114
1154.21 Sun Nov 25 10:48:59 CET 2007
116 - fix a spurious memory read.
117 - Coro::EV no longer keeps the eventloop "alive".
118
1194.2 Fri Nov 9 20:47:05 CET 2007
120 - enable/disable tracing from a new coroutine, not a pooled one.
121 - fix a memleak in Coro::Event.
122 - removed killall call from fork_eval.
123 - made sure store_fd is already loaded so that fork_eval
124 does not have to parse autoload in each subprocess.
125 - only use assembly method if -O switch is in $Config{optimize}.
126 - add (optional) Coro::EV module, so far the best event loop module
127 directly supported by Coro.
128 - if the event model is EV, use EV::DNS to resolve
129 stuff in Coro::Util.
130 - don't get confused by multiple event notifications in Coro::Handle.
131 - initial support for EV (libevent interface).
132 - require Event and EV using configure_requires, to force their existance.
133
1344.13 Wed Oct 24 07:26:45 CEST 2007
135 - add Coro::Storable::blocking_thaw.
136 - use a vastly more complicated technique to localise
137 $SIG{__WARN/DIE__} that also works on perls <= 5.8.8.
138 - use a coroutine for the idle callback Coro::Event,
139 instead of running Event in the current coroutine context.
140 This also catches recursive invocations.
141 - actually report fork errors in gethostbyname and inet_aton.
142
1434.11 Thu Oct 11 02:40:24 CEST 2007
144 - port to threaded perls.
145
1464.1 Thu Oct 11 02:38:16 CEST 2007
147 - incompatible change: $SIG{__DIE__} and $SIG{__WARN__} will now
148 be local to each coro (see Coro::State).
149 - incompatible change: for very deep reasons, cede and cede_notself
150 cannot return anything, so nothing will be returned.
151 - possibly bring back 5.10 compatibility (untested).
152 - work around stupid (and wrong) warning on 5.10 :(.
153 - overlay the saved state over the context stack. This saves
154 a few hundred bytes per coroutine on average and also
155 speeds up context switching a bit.
156 - further tune default stack sizes.
157 - (more) correctly calculate stack usage in coro_rss.
158 - Coro::Storable::blocking_* did not properly lock
159 resulting in races between coroutines.
160 - added Coro::Storable::guard.
161 - stopping to trace a coroutine could destroy the cctx of
162 an unrelated coroutine.
163 - explain the relationship between Perl and C coroutines in
164 more detail in Coro::State.
165 - Coro::Util::inet_aton did not short-circuit dotted quad forms,
166 causing a fork per resolve. This also affected Coro::Socket.
167 - switch to a separate stack in $coro->call/eval to avoid
168 invalidating pointers.
169
1704.03 Sat Oct 6 21:24:00 CEST 2007
171 - added Coro::throw method.
172 - minor code cleanups.
173
1744.02 Sat Oct 6 02:36:47 CEST 2007
175 - fix a very minor per-coroutine memleak (a single codereference).
176 - fixed a bug where the currently in-use c context would be freed
177 prematurely (can happen only when programs change the stacksize
178 or use tracing).
179 - tracing can no longer keep a coro alive after it terminated.
180 - do static branch prediction in the common path for gcc. gives
181 about 2-5% speed improvement here.
182
1834.01 Fri Oct 5 22:10:49 CEST 2007
184 - instead of recreating *a* standard output handle we simply
185 use STDOUT, which is faster and hopefully more robust.
186
1874.0 Fri Oct 5 12:56:00 CEST 2007
188 - incompatibly changed Coro::Storable::freeze.
189 - major new feature: added Coro::Debug, for interactive coroutine
190 debugging, tracing and much more.
191 - major bug fix: unbelievable, but true: $_, $/ and many other
192 "saved" variables actually weren't being saved. This has been fixed,
193 of course, while increasing performance while losing all the save
194 flags.
195 - save flags are gone, and all the api functions dealing with them.
196 - added Coro::Semaphore::adjust.
197 - added Coro::Util::fork_eval.
198 - added Coro::Storable::{nfreeze,blocking_{freeze,nfreeze}}.
199 - added Coro::killall.
200 - reduce initial stack sizes to allow for "micro-coroutines".
201 - better async_pool resource management, moved parts of async_pool
202 handling to XS (major speed improvement).
203 - actually croak before modifying important data structures.
204 - refuse to transfer while compiling.
205 - possibly support eval EXPR better now.
206 - enable assembly per default on linux+bsd x86+amd64.
207 - all internal members were renamed _something for easier subclassing.
208 - many minor tweaks.
209
2103.63 Wed May 16 14:10:06 CEST 2007
211 - implement handcoded assembly for x86/amd64 SVR ABI.
212
2133.62 Fri Apr 27 21:36:06 CEST 2007
214 - upgrade libcoro (which might set unwind info correctly).
215 - change default on linux to setjmp/longjmp.
216
2173.61 Thu Apr 19 12:36:18 CEST 2007
218 - Coro::Storable caused an endless loop when thawing invalid
219 pst's sometimes.
220 - use a Semaphore in Coro::Storable, as Storable doesn't
221 seem to be reentrant (although it is documented to
222 be threadsafe...).
223 - fix Coro::Signal to bring back the original unreliable
224 but stateful semantics.
225 - fixed a lot of typos in Coro.pm (patch submitted by David
226 Steinbrunner, which applied flawlessly).
227
2283.6 Sat Apr 14 17:13:31 CEST 2007
229 - added some bugfixes to get eg/myhttpd working again.
230 - added Coro::Storable for often-cede'ing freeze/thaw.
231 - try to do a clean exit when a coroutine calls exit
232 (EXPERIMENTAL).
233 - got rid of indirect call through _coro_init.
234 - updated the partly antique examples in eg/ to
235 work again and be a bit less magic, too.
236 - fixed Coro::Signal semantics to work as documented again.
237
2383.55 Sun Mar 25 01:20:47 CET 2007
239 - add SAVE_DEFFH to save the default filehandle and enable
240 it by default.
241 - finally move socket-operations from Coro::Socket to Coro::Handle
242 to be able to unblock foreign sockets.
243 - add Coro::State::save_also and guarded_save.
244 - add count accessor to Coro::Semaphore.
245 - add Coro::State::cctx_stacksize.
246 - just for the fun of it, do not rely on implicit context,
247 which can dramatically improve performance, but people
248 using windows-process-emulation perls do not care much about
249 performance.

63.51 Sun Mar 4 14:18:04 CET 2007 2513.51 Sun Mar 4 14:18:04 CET 2007
7 - fixed a problem when you weakened references to Coro::State's 252 - fixed a problem when you weakened references to Coro::State's
