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)).
5 7
63.3 84.47 Sun Apr 6 00:37:52 CEST 2008
9 - force cctx allocation on API calls: we know we need to force one
10 and gcc actually manages to confuse our heuristic nowadays,
11 leading to crashes and worse.
12 - document force_cctx.
13
144.46 Fri Apr 4 22:05:43 CEST 2008
15 - upgrade libcoro, resulting in pthread-backend (which was only created
16 to fulfill the rules of the programming languages shootout).
17
184.45 Thu Mar 13 11:55:36 CET 2008
19 - fix a file leaking bug in eg/mhyttpd that would allow
20 downloading of any file (reported by oesi).
21 - fix deadlock bug in Coro::Channel (reported by Richard Hundt)
22 (also add testcase).
23 - support Broadcast option in Coro::Socket (patch by Richard Hundt,
24 apparently having loads of fun with that).
25 - implement $state->swap_defsv, ->swap_defav and document ->throw.
26
274.4 Wed Feb 13 16:44:29 CET 2008
28 - only assume .cfi pseudo isns exist on GNU/Linux.
29 - add get_timed method to Coro::Channels.
30 - fixed Coro::Debug manpage.
31 - perl 5.11 compatbility improvement based on patch by
32 Andreas König.
33
344.37 Sun Jan 20 11:25:23 CET 2008
35 - soften the check for an active parser for perl 5.10 (avoiding
36 "Coro::State::transfer called while parsing" in many cases).
37
384.36 Sun Jan 13 10:53:56 CET 2008
39 - reset diehook when terminating from an async_pool as to not
40 trigger any __DIE__ handlers.
41
424.35 Sun Jan 13 04:14:13 CET 2008
43 - "bt" debug command now displays any exceptions
44 from longmess and also skips the innermost
45 stackframes, giving more useufl output.
46 - allow backtraces in coroutines blocked in Coro::EV,
47 at a <1% speed hit.
48 - handle localising of $SIG{__WARN__} and __DIE__
49 properly (with a proper amount of dirty hacking).
50
514.34 Sat Dec 22 17:49:53 CET 2007
52 - upgrade to EV version 2.0 API.
53
544.33 Mon Dec 17 08:36:12 CET 2007
55 - make Coro::AIO etc. loadable in the absence of EV.
56
574.32 Mon Dec 17 07:46:02 CET 2007
58 - majorly improved Coro::Handle's performance with Coro::EV.
59 - implemented the until now mythical Coro::BDB module.
60 - specialcase EV in Coro::AIO and Coro::BDB for extra speed.
61
624.31 Wed Dec 5 12:32:39 CET 2007
63 - remove warn statement form Coro::Util.
64
654.3 Tue Dec 4 20:33:14 CET 2007
66 - calls to the idle function could cause stack corruption
67 when the stack changed.
68 - do no longer rely on the presence of EV::DNS if EV is used
69 (because it is gone), but instead take avdantage of EV::ADNS
70 if available.
71 - add ($) prototypes to all functions in Coro::Storable.
72 - use a conventional (safer) idle callback in Coro::EV.
73 - do accept quickly in Coro::Debug to avoid endless loops.
74
754.22 Fri Nov 30 16:04:04 CET 2007
76 - really use optimised versions for Event and EV in Coro::Util
77 and Coro::Handle.
78
794.21 Sun Nov 25 10:48:59 CET 2007
80 - fix a spurious memory read.
81 - Coro::EV no longer keeps the eventloop "alive".
82
834.2 Fri Nov 9 20:47:05 CET 2007
84 - enable/disable tracing from a new coroutine, not a pooled one.
85 - fix a memleak in Coro::Event.
86 - removed killall call from fork_eval.
87 - made sure store_fd is already loaded so that fork_eval
88 does not have to parse autoload in each subprocess.
89 - only use assembly method if -O switch is in $Config{optimize}.
90 - add (optional) Coro::EV module, so far the best event loop module
91 directly supported by Coro.
92 - if the event model is EV, use EV::DNS to resolve
93 stuff in Coro::Util.
94 - don't get confused by multiple event notifications in Coro::Handle.
95 - initial support for EV (libevent interface).
96 - require Event and EV using configure_requires, to force their existance.
97
984.13 Wed Oct 24 07:26:45 CEST 2007
99 - add Coro::Storable::blocking_thaw.
100 - use a vastly more complicated technique to localise
101 $SIG{__WARN/DIE__} that also works on perls <= 5.8.8.
102 - use a coroutine for the idle callback Coro::Event,
103 instead of running Event in the current coroutine context.
104 This also catches recursive invocations.
105 - actually report fork errors in gethostbyname and inet_aton.
106
1074.11 Thu Oct 11 02:40:24 CEST 2007
108 - port to threaded perls.
109
1104.1 Thu Oct 11 02:38:16 CEST 2007
111 - incompatible change: $SIG{__DIE__} and $SIG{__WARN__} will now
112 be local to each coro (see Coro::State).
113 - incompatible change: for very deep reasons, cede and cede_notself
114 cannot return anything, so nothing will be returned.
115 - possibly bring back 5.10 compatibility (untested).
116 - work around stupid (and wrong) warning on 5.10 :(.
117 - overlay the saved state over the context stack. This saves
118 a few hundred bytes per coroutine on average and also
119 speeds up context switching a bit.
120 - further tune default stack sizes.
121 - (more) correctly calculate stack usage in coro_rss.
122 - Coro::Storable::blocking_* did not properly lock
123 resulting in races between coroutines.
124 - added Coro::Storable::guard.
125 - stopping to trace a coroutine could destroy the cctx of
126 an unrelated coroutine.
127 - explain the relationship between Perl and C coroutines in
128 more detail in Coro::State.
129 - Coro::Util::inet_aton did not short-circuit dotted quad forms,
130 causing a fork per resolve. This also affected Coro::Socket.
131 - switch to a separate stack in $coro->call/eval to avoid
132 invalidating pointers.
133
1344.03 Sat Oct 6 21:24:00 CEST 2007
135 - added Coro::throw method.
136 - minor code cleanups.
137
1384.02 Sat Oct 6 02:36:47 CEST 2007
139 - fix a very minor per-coroutine memleak (a single codereference).
140 - fixed a bug where the currently in-use c context would be freed
141 prematurely (can happen only when programs change the stacksize
142 or use tracing).
143 - tracing can no longer keep a coro alive after it terminated.
144 - do static branch prediction in the common path for gcc. gives
145 about 2-5% speed improvement here.
146
1474.01 Fri Oct 5 22:10:49 CEST 2007
148 - instead of recreating *a* standard output handle we simply
149 use STDOUT, which is faster and hopefully more robust.
150
1514.0 Fri Oct 5 12:56:00 CEST 2007
152 - incompatibly changed Coro::Storable::freeze.
153 - major new feature: added Coro::Debug, for interactive coroutine
154 debugging, tracing and much more.
155 - major bug fix: unbelievable, but true: $_, $/ and many other
156 "saved" variables actually weren't being saved. This has been fixed,
157 of course, while increasing performance while losing all the save
158 flags.
159 - save flags are gone, and all the api functions dealing with them.
160 - added Coro::Semaphore::adjust.
161 - added Coro::Util::fork_eval.
162 - added Coro::Storable::{nfreeze,blocking_{freeze,nfreeze}}.
163 - added Coro::killall.
164 - reduce initial stack sizes to allow for "micro-coroutines".
165 - better async_pool resource management, moved parts of async_pool
166 handling to XS (major speed improvement).
167 - actually croak before modifying important data structures.
168 - refuse to transfer while compiling.
169 - possibly support eval EXPR better now.
170 - enable assembly per default on linux+bsd x86+amd64.
171 - all internal members were renamed _something for easier subclassing.
172 - many minor tweaks.
173
1743.63 Wed May 16 14:10:06 CEST 2007
175 - implement handcoded assembly for x86/amd64 SVR ABI.
176
1773.62 Fri Apr 27 21:36:06 CEST 2007
178 - upgrade libcoro (which might set unwind info correctly).
179 - change default on linux to setjmp/longjmp.
180
1813.61 Thu Apr 19 12:36:18 CEST 2007
182 - Coro::Storable caused an endless loop when thawing invalid
183 pst's sometimes.
184 - use a Semaphore in Coro::Storable, as Storable doesn't
185 seem to be reentrant (although it is documented to
186 be threadsafe...).
187 - fix Coro::Signal to bring back the original unreliable
188 but stateful semantics.
189 - fixed a lot of typos in Coro.pm (patch submitted by David
190 Steinbrunner, which applied flawlessly).
191
1923.6 Sat Apr 14 17:13:31 CEST 2007
193 - added some bugfixes to get eg/myhttpd working again.
194 - added Coro::Storable for often-cede'ing freeze/thaw.
195 - try to do a clean exit when a coroutine calls exit
196 (EXPERIMENTAL).
197 - got rid of indirect call through _coro_init.
198 - updated the partly antique examples in eg/ to
199 work again and be a bit less magic, too.
200 - fixed Coro::Signal semantics to work as documented again.
201
2023.55 Sun Mar 25 01:20:47 CET 2007
203 - add SAVE_DEFFH to save the default filehandle and enable
204 it by default.
205 - finally move socket-operations from Coro::Socket to Coro::Handle
206 to be able to unblock foreign sockets.
207 - add Coro::State::save_also and guarded_save.
208 - add count accessor to Coro::Semaphore.
209 - add Coro::State::cctx_stacksize.
210 - just for the fun of it, do not rely on implicit context,
211 which can dramatically improve performance, but people
212 using windows-process-emulation perls do not care much about
213 performance.
214
2153.51 Sun Mar 4 14:18:04 CET 2007
216 - fixed a problem when you weakened references to Coro::State's
217 (patch by Yuval Kogman).
218
2193.501 Wed Feb 28 12:44:07 CET 2007
220 - rename some global symbols as macosx from hell redefines
221 them without asking.
222
2233.5 Tue Feb 13 20:22:53 CET 2007
224 - do AnyEvent model detection earlier, avoiding problems
225 caused by first using AnyEvent and later Coro::Event.
226 - implement and document Coro::Event event objects.
227 - fix a potential problem in Coro::Event causing crashes.
228 - initialise PL_comppad when creating a new coroutine,
229 avoids crashes on early coro destruction.
230
2313.41 Mon Jan 22 19:19:49 CET 2007
232 - readline on Coro::Handle did not support undefined $/,
233 nor did it deliver partial lines on EOF or error.
234 - implement malloc fallback for stack allocation because
235 stupid broken idiotic OSX has a stupid broken
236 idiotic fits-the-whole-os mmap "implementation" and
237 my dick feels longer if Coro is portable even to
238 obsolete platforms.
239
2403.4 Fri Jan 19 21:52:54 CET 2007
241 - remove t/09_timer.t, as it isn't really testing much
242 but was rather flaky in practise.
243 - async_pool coro would keep arguments and callback alive until
244 it was reused.
245 - cancellation of a coroutine could cause spurious idle calls
246 in cede_notself.
247
2483.3 Sat Jan 6 03:45:00 CET 2007
7 - implement $coro->on_destroy. 249 - implement $coro->on_destroy.
8 - Coro::Event blocking semantics have been changed, 250 - Coro::Event blocking semantics have been changed,
9 documented and - hopefully - improved. 251 documented and - hopefully - improved.
10 - fix nice adding, not subtracting, from priority. 252 - fix nice adding, not subtracting, from priority.
11 - fix ->prio and api_is_ready (patch by Mark Hinds). 253 - fix ->prio and api_is_ready (patch by Mark Hinds).
12 - fixed an assert ("... == prev__cctx->idle_te") 254 - fixed an assert ("... == prev__cctx->idle_te")
13 that could errronously trigger. 255 that could errronously trigger.
14 - fix various large and small memleaks. 256 - fix various large and small memleaks.
15 - use a (hopefully) more stable cancel implementation 257 - use a (hopefully) more stable cancel implementation
16 that immediately frees the coroutine data. 258 that immediately frees the coroutine data.
259 - cede/cede_notself return a status now.
17 - added Coro::guard function. 260 - added Coro::guard function.
261 - added a global coroutine pool for jobs (on my machine,
262 I can create and execute 48k simple coros/s with async,
263 and 128k coros with async_pool).
264 - Coro::AIO now uses the coroutine priority as io priority.
18 265
193.2 Fri Dec 22 05:07:09 CET 2006 2663.2 Fri Dec 22 05:07:09 CET 2006
