2 2
3TODO: transfer flags must be per state 3TODO: should explore PerlIO::via::CoroCede and PerlIO::via::CoroAIO.
4TODO: better (earlier) error messages on broken transfer's 4TODO: maybe implement a default message channel, very much like Erlang
5 (which is cool in a lot of important aspects (failures!),
6 but very lacking in others (higher level ipc)).
5 7
63. 8 - fix a file leaking bug in eg/mhyttpd that would allow
9 downloading of any file (reported by oesi).
10
114.4 Wed Feb 13 16:44:29 CET 2008
12 - only assume .cfi pseudo isns exist on GNU/Linux.
13 - add get_timed method to Coro::Channels.
14 - fixed Coro::Debug manpage.
15 - perl 5.11 compatbility improvement based on patch by
16 Andreas König.
17
184.37 Sun Jan 20 11:25:23 CET 2008
19 - soften the check for an active parser for perl 5.10 (avoiding
20 "Coro::State::transfer called while parsing" in many cases).
21
224.36 Sun Jan 13 10:53:56 CET 2008
23 - reset diehook when terminating from an async_pool as to not
24 trigger any __DIE__ handlers.
25
264.35 Sun Jan 13 04:14:13 CET 2008
27 - "bt" debug command now displays any exceptions
28 from longmess and also skips the innermost
29 stackframes, giving more useufl output.
30 - allow backtraces in coroutines blocked in Coro::EV,
31 at a <1% speed hit.
32 - handle localising of $SIG{__WARN__} and __DIE__
33 properly (with a proper amount of dirty hacking).
34
354.34 Sat Dec 22 17:49:53 CET 2007
36 - upgrade to EV version 2.0 API.
37
384.33 Mon Dec 17 08:36:12 CET 2007
39 - make Coro::AIO etc. loadable in the absence of EV.
40
414.32 Mon Dec 17 07:46:02 CET 2007
42 - majorly improved Coro::Handle's performance with Coro::EV.
43 - implemented the until now mythical Coro::BDB module.
44 - specialcase EV in Coro::AIO and Coro::BDB for extra speed.
45
464.31 Wed Dec 5 12:32:39 CET 2007
47 - remove warn statement form Coro::Util.
48
494.3 Tue Dec 4 20:33:14 CET 2007
50 - calls to the idle function could cause stack corruption
51 when the stack changed.
52 - do no longer rely on the presence of EV::DNS if EV is used
53 (because it is gone), but instead take avdantage of EV::ADNS
54 if available.
55 - add ($) prototypes to all functions in Coro::Storable.
56 - use a conventional (safer) idle callback in Coro::EV.
57 - do accept quickly in Coro::Debug to avoid endless loops.
58
594.22 Fri Nov 30 16:04:04 CET 2007
60 - really use optimised versions for Event and EV in Coro::Util
61 and Coro::Handle.
62
634.21 Sun Nov 25 10:48:59 CET 2007
64 - fix a spurious memory read.
65 - Coro::EV no longer keeps the eventloop "alive".
66
674.2 Fri Nov 9 20:47:05 CET 2007
68 - enable/disable tracing from a new coroutine, not a pooled one.
69 - fix a memleak in Coro::Event.
70 - removed killall call from fork_eval.
71 - made sure store_fd is already loaded so that fork_eval
72 does not have to parse autoload in each subprocess.
73 - only use assembly method if -O switch is in $Config{optimize}.
74 - add (optional) Coro::EV module, so far the best event loop module
75 directly supported by Coro.
76 - if the event model is EV, use EV::DNS to resolve
77 stuff in Coro::Util.
78 - don't get confused by multiple event notifications in Coro::Handle.
79 - initial support for EV (libevent interface).
80 - require Event and EV using configure_requires, to force their existance.
81
824.13 Wed Oct 24 07:26:45 CEST 2007
83 - add Coro::Storable::blocking_thaw.
84 - use a vastly more complicated technique to localise
85 $SIG{__WARN/DIE__} that also works on perls <= 5.8.8.
86 - use a coroutine for the idle callback Coro::Event,
87 instead of running Event in the current coroutine context.
88 This also catches recursive invocations.
89 - actually report fork errors in gethostbyname and inet_aton.
90
914.11 Thu Oct 11 02:40:24 CEST 2007
92 - port to threaded perls.
93
944.1 Thu Oct 11 02:38:16 CEST 2007
95 - incompatible change: $SIG{__DIE__} and $SIG{__WARN__} will now
96 be local to each coro (see Coro::State).
97 - incompatible change: for very deep reasons, cede and cede_notself
98 cannot return anything, so nothing will be returned.
99 - possibly bring back 5.10 compatibility (untested).
100 - work around stupid (and wrong) warning on 5.10 :(.
101 - overlay the saved state over the context stack. This saves
102 a few hundred bytes per coroutine on average and also
103 speeds up context switching a bit.
104 - further tune default stack sizes.
105 - (more) correctly calculate stack usage in coro_rss.
106 - Coro::Storable::blocking_* did not properly lock
107 resulting in races between coroutines.
108 - added Coro::Storable::guard.
109 - stopping to trace a coroutine could destroy the cctx of
110 an unrelated coroutine.
111 - explain the relationship between Perl and C coroutines in
112 more detail in Coro::State.
113 - Coro::Util::inet_aton did not short-circuit dotted quad forms,
114 causing a fork per resolve. This also affected Coro::Socket.
115 - switch to a separate stack in $coro->call/eval to avoid
116 invalidating pointers.
117
1184.03 Sat Oct 6 21:24:00 CEST 2007
119 - added Coro::throw method.
120 - minor code cleanups.
121
1224.02 Sat Oct 6 02:36:47 CEST 2007
123 - fix a very minor per-coroutine memleak (a single codereference).
124 - fixed a bug where the currently in-use c context would be freed
125 prematurely (can happen only when programs change the stacksize
126 or use tracing).
127 - tracing can no longer keep a coro alive after it terminated.
128 - do static branch prediction in the common path for gcc. gives
129 about 2-5% speed improvement here.
130
1314.01 Fri Oct 5 22:10:49 CEST 2007
132 - instead of recreating *a* standard output handle we simply
133 use STDOUT, which is faster and hopefully more robust.
134
1354.0 Fri Oct 5 12:56:00 CEST 2007
136 - incompatibly changed Coro::Storable::freeze.
137 - major new feature: added Coro::Debug, for interactive coroutine
138 debugging, tracing and much more.
139 - major bug fix: unbelievable, but true: $_, $/ and many other
140 "saved" variables actually weren't being saved. This has been fixed,
141 of course, while increasing performance while losing all the save
142 flags.
143 - save flags are gone, and all the api functions dealing with them.
144 - added Coro::Semaphore::adjust.
145 - added Coro::Util::fork_eval.
146 - added Coro::Storable::{nfreeze,blocking_{freeze,nfreeze}}.
147 - added Coro::killall.
148 - reduce initial stack sizes to allow for "micro-coroutines".
149 - better async_pool resource management, moved parts of async_pool
150 handling to XS (major speed improvement).
151 - actually croak before modifying important data structures.
152 - refuse to transfer while compiling.
153 - possibly support eval EXPR better now.
154 - enable assembly per default on linux+bsd x86+amd64.
155 - all internal members were renamed _something for easier subclassing.
156 - many minor tweaks.
157
1583.63 Wed May 16 14:10:06 CEST 2007
159 - implement handcoded assembly for x86/amd64 SVR ABI.
160
1613.62 Fri Apr 27 21:36:06 CEST 2007
162 - upgrade libcoro (which might set unwind info correctly).
163 - change default on linux to setjmp/longjmp.
164
1653.61 Thu Apr 19 12:36:18 CEST 2007
166 - Coro::Storable caused an endless loop when thawing invalid
167 pst's sometimes.
168 - use a Semaphore in Coro::Storable, as Storable doesn't
169 seem to be reentrant (although it is documented to
170 be threadsafe...).
171 - fix Coro::Signal to bring back the original unreliable
172 but stateful semantics.
173 - fixed a lot of typos in Coro.pm (patch submitted by David
174 Steinbrunner, which applied flawlessly).
175
1763.6 Sat Apr 14 17:13:31 CEST 2007
177 - added some bugfixes to get eg/myhttpd working again.
178 - added Coro::Storable for often-cede'ing freeze/thaw.
179 - try to do a clean exit when a coroutine calls exit
180 (EXPERIMENTAL).
181 - got rid of indirect call through _coro_init.
182 - updated the partly antique examples in eg/ to
183 work again and be a bit less magic, too.
184 - fixed Coro::Signal semantics to work as documented again.
185
1863.55 Sun Mar 25 01:20:47 CET 2007
187 - add SAVE_DEFFH to save the default filehandle and enable
188 it by default.
189 - finally move socket-operations from Coro::Socket to Coro::Handle
190 to be able to unblock foreign sockets.
191 - add Coro::State::save_also and guarded_save.
192 - add count accessor to Coro::Semaphore.
193 - add Coro::State::cctx_stacksize.
194 - just for the fun of it, do not rely on implicit context,
195 which can dramatically improve performance, but people
196 using windows-process-emulation perls do not care much about
197 performance.
198
1993.51 Sun Mar 4 14:18:04 CET 2007
200 - fixed a problem when you weakened references to Coro::State's
201 (patch by Yuval Kogman).
202
2033.501 Wed Feb 28 12:44:07 CET 2007
204 - rename some global symbols as macosx from hell redefines
205 them without asking.
206
2073.5 Tue Feb 13 20:22:53 CET 2007
208 - do AnyEvent model detection earlier, avoiding problems
209 caused by first using AnyEvent and later Coro::Event.
210 - implement and document Coro::Event event objects.
211 - fix a potential problem in Coro::Event causing crashes.
212 - initialise PL_comppad when creating a new coroutine,
213 avoids crashes on early coro destruction.
214
2153.41 Mon Jan 22 19:19:49 CET 2007
216 - readline on Coro::Handle did not support undefined $/,
217 nor did it deliver partial lines on EOF or error.
218 - implement malloc fallback for stack allocation because
219 stupid broken idiotic OSX has a stupid broken
220 idiotic fits-the-whole-os mmap "implementation" and
221 my dick feels longer if Coro is portable even to
222 obsolete platforms.
223
2243.4 Fri Jan 19 21:52:54 CET 2007
225 - remove t/09_timer.t, as it isn't really testing much
226 but was rather flaky in practise.
227 - async_pool coro would keep arguments and callback alive until
228 it was reused.
229 - cancellation of a coroutine could cause spurious idle calls
230 in cede_notself.
231
2323.3 Sat Jan 6 03:45:00 CET 2007
233 - implement $coro->on_destroy.
234 - Coro::Event blocking semantics have been changed,
235 documented and - hopefully - improved.
236 - fix nice adding, not subtracting, from priority.
237 - fix ->prio and api_is_ready (patch by Mark Hinds).
238 - fixed an assert ("... == prev__cctx->idle_te")
239 that could errronously trigger.
240 - fix various large and small memleaks.
241 - use a (hopefully) more stable cancel implementation
242 that immediately frees the coroutine data.
243 - cede/cede_notself return a status now.
244 - added Coro::guard function.
245 - added a global coroutine pool for jobs (on my machine,
246 I can create and execute 48k simple coros/s with async,
247 and 128k coros with async_pool).
248 - Coro::AIO now uses the coroutine priority as io priority.
249
2503.2 Fri Dec 22 05:07:09 CET 2006
251 - improve portability to slightly older perls.
252 - use cleaner coroutine destruction.
253 - simplify configuration for users.
254 - optionally (unrecommended) prefer perl functions over
255 their coro replacements.
256
2573.11 Tue Dec 5 13:11:24 CET 2006
258 - fixed some bogus assert's, but as perl.h disables assert even
259 without NDEBUG (thank you very much), not too many people should
260 notice (that did include myself). Andreas König noticed, though :)
261 - do not save/restore PL_sortcxix on >= 5.9.x, it doesn't seem to have
262 it. Also noticed by Andreas König :)
263 - save/restore tainted status.
264 - verified to pass the testsuite on my 5.9.5.
265
2663.1 Mon Dec 4 23:03:40 CET 2006
267 - INCOMPATIBLE CHANGE: $/ is now per-coroutine (but slow).
268 - incompatible change: transfer flags are now per-state.
7 - give a better error message on deadlock. 269 - give a better error message on deadlock.
270 - document Coro::nready.
271 - enhanced testsuite.
8 272
93.01 Sun Dec 3 23:47:42 CET 2006 2733.01 Sun Dec 3 23:47:42 CET 2006
10 - forgot to include Coro::Timer. 274 - forgot to include Coro::Timer.
11 275
123.0 Sun Dec 3 22:57:25 CET 2006 2763.0 Sun Dec 3 22:57:25 CET 2006
