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
5 (which is cool in a lot of important aspects (failures!),
6 but very lacking in others (higher level ipc)).
5 7
63.3 84.33 Mon Dec 17 08:36:12 CET 2007
9 - make Coro::AIO etc. loadable in the absence of EV.
10
114.32 Mon Dec 17 07:46:02 CET 2007
12 - majorly improved Coro::Handle's performance with Coro::EV.
13 - implemented the until now mythical Coro::BDB module.
14 - specialcase EV in Coro::AIO and Coro::BDB for extra speed.
15
164.31 Wed Dec 5 12:32:39 CET 2007
17 - remove warn statement form Coro::Util.
18
194.3 Tue Dec 4 20:33:14 CET 2007
20 - calls to the idle function could cause stack corruption
21 when the stack changed.
22 - do no longer rely on the presence of EV::DNS if EV is used
23 (because it is gone), but instead take avdantage of EV::ADNS
24 if available.
25 - add ($) prototypes to all functions in Coro::Storable.
26 - use a conventional (safer) idle callback in Coro::EV.
27 - do accept quickly in Coro::Debug to avoid endless loops.
28
294.22 Fri Nov 30 16:04:04 CET 2007
30 - really use optimised versions for Event and EV in Coro::Util
31 and Coro::Handle.
32
334.21 Sun Nov 25 10:48:59 CET 2007
34 - fix a spurious memory read.
35 - Coro::EV no longer keeps the eventloop "alive".
36
374.2 Fri Nov 9 20:47:05 CET 2007
38 - enable/disable tracing from a new coroutine, not a pooled one.
39 - fix a memleak in Coro::Event.
40 - removed killall call from fork_eval.
41 - made sure store_fd is already loaded so that fork_eval
42 does not have to parse autoload in each subprocess.
43 - only use assembly method if -O switch is in $Config{optimize}.
44 - add (optional) Coro::EV module, so far the best event loop module
45 directly supported by Coro.
46 - if the event model is EV, use EV::DNS to resolve
47 stuff in Coro::Util.
48 - don't get confused by multiple event notifications in Coro::Handle.
49 - initial support for EV (libevent interface).
50 - require Event and EV using configure_requires, to force their existance.
51
524.13 Wed Oct 24 07:26:45 CEST 2007
53 - add Coro::Storable::blocking_thaw.
54 - use a vastly more complicated technique to localise
55 $SIG{__WARN/DIE__} that also works on perls <= 5.8.8.
56 - use a coroutine for the idle callback Coro::Event,
57 instead of running Event in the current coroutine context.
58 This also catches recursive invocations.
59 - actually report fork errors in gethostbyname and inet_aton.
60
614.11 Thu Oct 11 02:40:24 CEST 2007
62 - port to threaded perls.
63
644.1 Thu Oct 11 02:38:16 CEST 2007
65 - incompatible change: $SIG{__DIE__} and $SIG{__WARN__} will now
66 be local to each coro (see Coro::State).
67 - incompatible change: for very deep reasons, cede and cede_notself
68 cannot return anything, so nothing will be returned.
69 - possibly bring back 5.10 compatibility (untested).
70 - work around stupid (and wrong) warning on 5.10 :(.
71 - overlay the saved state over the context stack. This saves
72 a few hundred bytes per coroutine on average and also
73 speeds up context switching a bit.
74 - further tune default stack sizes.
75 - (more) correctly calculate stack usage in coro_rss.
76 - Coro::Storable::blocking_* did not properly lock
77 resulting in races between coroutines.
78 - added Coro::Storable::guard.
79 - stopping to trace a coroutine could destroy the cctx of
80 an unrelated coroutine.
81 - explain the relationship between Perl and C coroutines in
82 more detail in Coro::State.
83 - Coro::Util::inet_aton did not short-circuit dotted quad forms,
84 causing a fork per resolve. This also affected Coro::Socket.
85 - switch to a separate stack in $coro->call/eval to avoid
86 invalidating pointers.
87
884.03 Sat Oct 6 21:24:00 CEST 2007
89 - added Coro::throw method.
90 - minor code cleanups.
91
924.02 Sat Oct 6 02:36:47 CEST 2007
93 - fix a very minor per-coroutine memleak (a single codereference).
94 - fixed a bug where the currently in-use c context would be freed
95 prematurely (can happen only when programs change the stacksize
96 or use tracing).
97 - tracing can no longer keep a coro alive after it terminated.
98 - do static branch prediction in the common path for gcc. gives
99 about 2-5% speed improvement here.
100
1014.01 Fri Oct 5 22:10:49 CEST 2007
102 - instead of recreating *a* standard output handle we simply
103 use STDOUT, which is faster and hopefully more robust.
104
1054.0 Fri Oct 5 12:56:00 CEST 2007
106 - incompatibly changed Coro::Storable::freeze.
107 - major new feature: added Coro::Debug, for interactive coroutine
108 debugging, tracing and much more.
109 - major bug fix: unbelievable, but true: $_, $/ and many other
110 "saved" variables actually weren't being saved. This has been fixed,
111 of course, while increasing performance while losing all the save
112 flags.
113 - save flags are gone, and all the api functions dealing with them.
114 - added Coro::Semaphore::adjust.
115 - added Coro::Util::fork_eval.
116 - added Coro::Storable::{nfreeze,blocking_{freeze,nfreeze}}.
117 - added Coro::killall.
118 - reduce initial stack sizes to allow for "micro-coroutines".
119 - better async_pool resource management, moved parts of async_pool
120 handling to XS (major speed improvement).
121 - actually croak before modifying important data structures.
122 - refuse to transfer while compiling.
123 - possibly support eval EXPR better now.
124 - enable assembly per default on linux+bsd x86+amd64.
125 - all internal members were renamed _something for easier subclassing.
126 - many minor tweaks.
127
1283.63 Wed May 16 14:10:06 CEST 2007
129 - implement handcoded assembly for x86/amd64 SVR ABI.
130
1313.62 Fri Apr 27 21:36:06 CEST 2007
132 - upgrade libcoro (which might set unwind info correctly).
133 - change default on linux to setjmp/longjmp.
134
1353.61 Thu Apr 19 12:36:18 CEST 2007
136 - Coro::Storable caused an endless loop when thawing invalid
137 pst's sometimes.
138 - use a Semaphore in Coro::Storable, as Storable doesn't
139 seem to be reentrant (although it is documented to
140 be threadsafe...).
141 - fix Coro::Signal to bring back the original unreliable
142 but stateful semantics.
143 - fixed a lot of typos in Coro.pm (patch submitted by David
144 Steinbrunner, which applied flawlessly).
145
1463.6 Sat Apr 14 17:13:31 CEST 2007
147 - added some bugfixes to get eg/myhttpd working again.
148 - added Coro::Storable for often-cede'ing freeze/thaw.
149 - try to do a clean exit when a coroutine calls exit
150 (EXPERIMENTAL).
151 - got rid of indirect call through _coro_init.
152 - updated the partly antique examples in eg/ to
153 work again and be a bit less magic, too.
154 - fixed Coro::Signal semantics to work as documented again.
155
1563.55 Sun Mar 25 01:20:47 CET 2007
157 - add SAVE_DEFFH to save the default filehandle and enable
158 it by default.
159 - finally move socket-operations from Coro::Socket to Coro::Handle
160 to be able to unblock foreign sockets.
161 - add Coro::State::save_also and guarded_save.
162 - add count accessor to Coro::Semaphore.
163 - add Coro::State::cctx_stacksize.
164 - just for the fun of it, do not rely on implicit context,
165 which can dramatically improve performance, but people
166 using windows-process-emulation perls do not care much about
167 performance.
168
1693.51 Sun Mar 4 14:18:04 CET 2007
170 - fixed a problem when you weakened references to Coro::State's
171 (patch by Yuval Kogman).
172
1733.501 Wed Feb 28 12:44:07 CET 2007
174 - rename some global symbols as macosx from hell redefines
175 them without asking.
176
1773.5 Tue Feb 13 20:22:53 CET 2007
178 - do AnyEvent model detection earlier, avoiding problems
179 caused by first using AnyEvent and later Coro::Event.
180 - implement and document Coro::Event event objects.
181 - fix a potential problem in Coro::Event causing crashes.
182 - initialise PL_comppad when creating a new coroutine,
183 avoids crashes on early coro destruction.
184
1853.41 Mon Jan 22 19:19:49 CET 2007
186 - readline on Coro::Handle did not support undefined $/,
187 nor did it deliver partial lines on EOF or error.
188 - implement malloc fallback for stack allocation because
189 stupid broken idiotic OSX has a stupid broken
190 idiotic fits-the-whole-os mmap "implementation" and
191 my dick feels longer if Coro is portable even to
192 obsolete platforms.
193
1943.4 Fri Jan 19 21:52:54 CET 2007
195 - remove t/09_timer.t, as it isn't really testing much
196 but was rather flaky in practise.
197 - async_pool coro would keep arguments and callback alive until
198 it was reused.
199 - cancellation of a coroutine could cause spurious idle calls
200 in cede_notself.
201
2023.3 Sat Jan 6 03:45:00 CET 2007
7 - implement $coro->on_destroy. 203 - implement $coro->on_destroy.

11 - fix ->prio and api_is_ready (patch by Mark Hinds). 207 - fix ->prio and api_is_ready (patch by Mark Hinds).
12 - fixed an assert ("... == prev__cctx->idle_te") 208 - fixed an assert ("... == prev__cctx->idle_te")
13 that could errronously trigger. 209 that could errronously trigger.
210 - fix various large and small memleaks.
14 - use a (hopefully) more stable cancel implementation 211 - use a (hopefully) more stable cancel implementation
15 that immediately frees the coroutine data. 212 that immediately frees the coroutine data.
213 - cede/cede_notself return a status now.
16 - added Coro::guard function. 214 - added Coro::guard function.
215 - added a global coroutine pool for jobs (on my machine,
216 I can create and execute 48k simple coros/s with async,
217 and 128k coros with async_pool).
218 - Coro::AIO now uses the coroutine priority as io priority.
17 219
183.2 Fri Dec 22 05:07:09 CET 2006 2203.2 Fri Dec 22 05:07:09 CET 2006
