3TODO: better (earlier) error messages on broken transfer's 3TODO: should explore PerlIO::via::CoroCede and PerlIO::via::CoroAIO.
4TODO: "internals mode" 4TODO: maybe implement a default message channel, very much like Erlang
5TODO: "use defaults for everything" 5 (which is cool in a lot of important aspects (failures!),
6 but very lacking in others (higher level ipc)).
6 7
84.34
9 - upgrade to EV version 2.0 API.
10
114.33 Mon Dec 17 08:36:12 CET 2007
12 - make Coro::AIO etc. loadable in the absence of EV.
13
144.32 Mon Dec 17 07:46:02 CET 2007
15 - majorly improved Coro::Handle's performance with Coro::EV.
16 - implemented the until now mythical Coro::BDB module.
17 - specialcase EV in Coro::AIO and Coro::BDB for extra speed.
18
194.31 Wed Dec 5 12:32:39 CET 2007
20 - remove warn statement form Coro::Util.
21
224.3 Tue Dec 4 20:33:14 CET 2007
23 - calls to the idle function could cause stack corruption
24 when the stack changed.
25 - do no longer rely on the presence of EV::DNS if EV is used
26 (because it is gone), but instead take avdantage of EV::ADNS
27 if available.
28 - add ($) prototypes to all functions in Coro::Storable.
29 - use a conventional (safer) idle callback in Coro::EV.
30 - do accept quickly in Coro::Debug to avoid endless loops.
31
324.22 Fri Nov 30 16:04:04 CET 2007
33 - really use optimised versions for Event and EV in Coro::Util
34 and Coro::Handle.
35
364.21 Sun Nov 25 10:48:59 CET 2007
37 - fix a spurious memory read.
38 - Coro::EV no longer keeps the eventloop "alive".
39
404.2 Fri Nov 9 20:47:05 CET 2007
41 - enable/disable tracing from a new coroutine, not a pooled one.
42 - fix a memleak in Coro::Event.
43 - removed killall call from fork_eval.
44 - made sure store_fd is already loaded so that fork_eval
45 does not have to parse autoload in each subprocess.
46 - only use assembly method if -O switch is in $Config{optimize}.
47 - add (optional) Coro::EV module, so far the best event loop module
48 directly supported by Coro.
49 - if the event model is EV, use EV::DNS to resolve
50 stuff in Coro::Util.
51 - don't get confused by multiple event notifications in Coro::Handle.
52 - initial support for EV (libevent interface).
53 - require Event and EV using configure_requires, to force their existance.
54
554.13 Wed Oct 24 07:26:45 CEST 2007
56 - add Coro::Storable::blocking_thaw.
57 - use a vastly more complicated technique to localise
58 $SIG{__WARN/DIE__} that also works on perls <= 5.8.8.
59 - use a coroutine for the idle callback Coro::Event,
60 instead of running Event in the current coroutine context.
61 This also catches recursive invocations.
62 - actually report fork errors in gethostbyname and inet_aton.
63
644.11 Thu Oct 11 02:40:24 CEST 2007
65 - port to threaded perls.
66
674.1 Thu Oct 11 02:38:16 CEST 2007
68 - incompatible change: $SIG{__DIE__} and $SIG{__WARN__} will now
69 be local to each coro (see Coro::State).
70 - incompatible change: for very deep reasons, cede and cede_notself
71 cannot return anything, so nothing will be returned.
72 - possibly bring back 5.10 compatibility (untested).
73 - work around stupid (and wrong) warning on 5.10 :(.
74 - overlay the saved state over the context stack. This saves
75 a few hundred bytes per coroutine on average and also
76 speeds up context switching a bit.
77 - further tune default stack sizes.
78 - (more) correctly calculate stack usage in coro_rss.
79 - Coro::Storable::blocking_* did not properly lock
80 resulting in races between coroutines.
81 - added Coro::Storable::guard.
82 - stopping to trace a coroutine could destroy the cctx of
83 an unrelated coroutine.
84 - explain the relationship between Perl and C coroutines in
85 more detail in Coro::State.
86 - Coro::Util::inet_aton did not short-circuit dotted quad forms,
87 causing a fork per resolve. This also affected Coro::Socket.
88 - switch to a separate stack in $coro->call/eval to avoid
89 invalidating pointers.
90
914.03 Sat Oct 6 21:24:00 CEST 2007
92 - added Coro::throw method.
93 - minor code cleanups.
94
954.02 Sat Oct 6 02:36:47 CEST 2007
96 - fix a very minor per-coroutine memleak (a single codereference).
97 - fixed a bug where the currently in-use c context would be freed
98 prematurely (can happen only when programs change the stacksize
99 or use tracing).
100 - tracing can no longer keep a coro alive after it terminated.
101 - do static branch prediction in the common path for gcc. gives
102 about 2-5% speed improvement here.
103
1044.01 Fri Oct 5 22:10:49 CEST 2007
105 - instead of recreating *a* standard output handle we simply
106 use STDOUT, which is faster and hopefully more robust.
107
1084.0 Fri Oct 5 12:56:00 CEST 2007
109 - incompatibly changed Coro::Storable::freeze.
110 - major new feature: added Coro::Debug, for interactive coroutine
111 debugging, tracing and much more.
112 - major bug fix: unbelievable, but true: $_, $/ and many other
113 "saved" variables actually weren't being saved. This has been fixed,
114 of course, while increasing performance while losing all the save
115 flags.
116 - save flags are gone, and all the api functions dealing with them.
117 - added Coro::Semaphore::adjust.
118 - added Coro::Util::fork_eval.
119 - added Coro::Storable::{nfreeze,blocking_{freeze,nfreeze}}.
120 - added Coro::killall.
121 - reduce initial stack sizes to allow for "micro-coroutines".
122 - better async_pool resource management, moved parts of async_pool
123 handling to XS (major speed improvement).
124 - actually croak before modifying important data structures.
125 - refuse to transfer while compiling.
126 - possibly support eval EXPR better now.
127 - enable assembly per default on linux+bsd x86+amd64.
128 - all internal members were renamed _something for easier subclassing.
129 - many minor tweaks.
130
1313.63 Wed May 16 14:10:06 CEST 2007
132 - implement handcoded assembly for x86/amd64 SVR ABI.
133
1343.62 Fri Apr 27 21:36:06 CEST 2007
135 - upgrade libcoro (which might set unwind info correctly).
136 - change default on linux to setjmp/longjmp.
137
1383.61 Thu Apr 19 12:36:18 CEST 2007
139 - Coro::Storable caused an endless loop when thawing invalid
140 pst's sometimes.
141 - use a Semaphore in Coro::Storable, as Storable doesn't
142 seem to be reentrant (although it is documented to
143 be threadsafe...).
144 - fix Coro::Signal to bring back the original unreliable
145 but stateful semantics.
146 - fixed a lot of typos in Coro.pm (patch submitted by David
147 Steinbrunner, which applied flawlessly).
148
1493.6 Sat Apr 14 17:13:31 CEST 2007
150 - added some bugfixes to get eg/myhttpd working again.
151 - added Coro::Storable for often-cede'ing freeze/thaw.
152 - try to do a clean exit when a coroutine calls exit
153 (EXPERIMENTAL).
154 - got rid of indirect call through _coro_init.
155 - updated the partly antique examples in eg/ to
156 work again and be a bit less magic, too.
157 - fixed Coro::Signal semantics to work as documented again.
158
1593.55 Sun Mar 25 01:20:47 CET 2007
160 - add SAVE_DEFFH to save the default filehandle and enable
161 it by default.
162 - finally move socket-operations from Coro::Socket to Coro::Handle
163 to be able to unblock foreign sockets.
164 - add Coro::State::save_also and guarded_save.
165 - add count accessor to Coro::Semaphore.
166 - add Coro::State::cctx_stacksize.
167 - just for the fun of it, do not rely on implicit context,
168 which can dramatically improve performance, but people
169 using windows-process-emulation perls do not care much about
170 performance.
171
1723.51 Sun Mar 4 14:18:04 CET 2007
173 - fixed a problem when you weakened references to Coro::State's
174 (patch by Yuval Kogman).
175
1763.501 Wed Feb 28 12:44:07 CET 2007
177 - rename some global symbols as macosx from hell redefines
178 them without asking.
179
1803.5 Tue Feb 13 20:22:53 CET 2007
181 - do AnyEvent model detection earlier, avoiding problems
182 caused by first using AnyEvent and later Coro::Event.
183 - implement and document Coro::Event event objects.
184 - fix a potential problem in Coro::Event causing crashes.
185 - initialise PL_comppad when creating a new coroutine,
186 avoids crashes on early coro destruction.
187
1883.41 Mon Jan 22 19:19:49 CET 2007
189 - readline on Coro::Handle did not support undefined $/,
190 nor did it deliver partial lines on EOF or error.
191 - implement malloc fallback for stack allocation because
192 stupid broken idiotic OSX has a stupid broken
193 idiotic fits-the-whole-os mmap "implementation" and
194 my dick feels longer if Coro is portable even to
195 obsolete platforms.
196
1973.4 Fri Jan 19 21:52:54 CET 2007
198 - remove t/09_timer.t, as it isn't really testing much
199 but was rather flaky in practise.
200 - async_pool coro would keep arguments and callback alive until
201 it was reused.
202 - cancellation of a coroutine could cause spurious idle calls
203 in cede_notself.
204
2053.3 Sat Jan 6 03:45:00 CET 2007
206 - implement $coro->on_destroy.
207 - Coro::Event blocking semantics have been changed,
208 documented and - hopefully - improved.
209 - fix nice adding, not subtracting, from priority.
210 - fix ->prio and api_is_ready (patch by Mark Hinds).
211 - fixed an assert ("... == prev__cctx->idle_te")
212 that could errronously trigger.
213 - fix various large and small memleaks.
214 - use a (hopefully) more stable cancel implementation
215 that immediately frees the coroutine data.
216 - cede/cede_notself return a status now.
217 - added Coro::guard function.
218 - added a global coroutine pool for jobs (on my machine,
219 I can create and execute 48k simple coros/s with async,
220 and 128k coros with async_pool).
221 - Coro::AIO now uses the coroutine priority as io priority.
222
2233.2 Fri Dec 22 05:07:09 CET 2006
7 - improve portability to slightly older perls. 224 - improve portability to slightly older perls.
8 - use cleaner coroutine destruction. 225 - use cleaner coroutine destruction.
226 - simplify configuration for users.
227 - optionally (unrecommended) prefer perl functions over
228 their coro replacements.
