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 8 - enable/disable tracing from a new coroutine, not a pooled one.
9 - fix a memleak in Coro::Event.
10 - removed killall call from fork_eval.
11 - made sure store_fd is already loaded so that fork_eval
12 does not have to parse autoload in each subprocess.
13 - if the event model is EV, use EV::DNS to resolve
14 stuff in Coro::Util.
15 - don't get confused by multiple event notifications in Coro::Handle.
16
174.13 Wed Oct 24 07:26:45 CEST 2007
18 - add Coro::Storable::blocking_thaw.
19 - use a vastly more complicated technique to localise
20 $SIG{__WARN/DIE__} that also works on perls <= 5.8.8.
21 - use a coroutine for the idle callback Coro::Event,
22 instead of running Event in the current coroutine context.
23 This also catches recursive invocations.
24 - actually report fork errors in gethostbyname and inet_aton.
25
264.11 Thu Oct 11 02:40:24 CEST 2007
27 - port to threaded perls.
28
294.1 Thu Oct 11 02:38:16 CEST 2007
30 - incompatible change: $SIG{__DIE__} and $SIG{__WARN__} will now
31 be local to each coro (see Coro::State).
32 - incompatible change: for very deep reasons, cede and cede_notself
33 cannot return anything, so nothing will be returned.
34 - possibly bring back 5.10 compatibility (untested).
35 - work around stupid (and wrong) warning on 5.10 :(.
36 - overlay the saved state over the context stack. This saves
37 a few hundred bytes per coroutine on average and also
38 speeds up context switching a bit.
39 - further tune default stack sizes.
40 - (more) correctly calculate stack usage in coro_rss.
41 - Coro::Storable::blocking_* did not properly lock
42 resulting in races between coroutines.
43 - added Coro::Storable::guard.
44 - stopping to trace a coroutine could destroy the cctx of
45 an unrelated coroutine.
46 - explain the relationship between Perl and C coroutines in
47 more detail in Coro::State.
48 - Coro::Util::inet_aton did not short-circuit dotted quad forms,
49 causing a fork per resolve. This also affected Coro::Socket.
50 - switch to a separate stack in $coro->call/eval to avoid
51 invalidating pointers.
52
534.03 Sat Oct 6 21:24:00 CEST 2007
54 - added Coro::throw method.
55 - minor code cleanups.
56
574.02 Sat Oct 6 02:36:47 CEST 2007
58 - fix a very minor per-coroutine memleak (a single codereference).
59 - fixed a bug where the currently in-use c context would be freed
60 prematurely (can happen only when programs change the stacksize
61 or use tracing).
62 - tracing can no longer keep a coro alive after it terminated.
63 - do static branch prediction in the common path for gcc. gives
64 about 2-5% speed improvement here.
65
664.01 Fri Oct 5 22:10:49 CEST 2007
67 - instead of recreating *a* standard output handle we simply
68 use STDOUT, which is faster and hopefully more robust.
69
704.0 Fri Oct 5 12:56:00 CEST 2007
71 - incompatibly changed Coro::Storable::freeze.
72 - major new feature: added Coro::Debug, for interactive coroutine
73 debugging, tracing and much more.
74 - major bug fix: unbelievable, but true: $_, $/ and many other
75 "saved" variables actually weren't being saved. This has been fixed,
76 of course, while increasing performance while losing all the save
77 flags.
78 - save flags are gone, and all the api functions dealing with them.
79 - added Coro::Semaphore::adjust.
80 - added Coro::Util::fork_eval.
81 - added Coro::Storable::{nfreeze,blocking_{freeze,nfreeze}}.
82 - added Coro::killall.
83 - reduce initial stack sizes to allow for "micro-coroutines".
84 - better async_pool resource management, moved parts of async_pool
85 handling to XS (major speed improvement).
86 - actually croak before modifying important data structures.
87 - refuse to transfer while compiling.
88 - possibly support eval EXPR better now.
89 - enable assembly per default on linux+bsd x86+amd64.
90 - all internal members were renamed _something for easier subclassing.
91 - many minor tweaks.
92
933.63 Wed May 16 14:10:06 CEST 2007
94 - implement handcoded assembly for x86/amd64 SVR ABI.
95
963.62 Fri Apr 27 21:36:06 CEST 2007
97 - upgrade libcoro (which might set unwind info correctly).
98 - change default on linux to setjmp/longjmp.
99
1003.61 Thu Apr 19 12:36:18 CEST 2007
101 - Coro::Storable caused an endless loop when thawing invalid
102 pst's sometimes.
103 - use a Semaphore in Coro::Storable, as Storable doesn't
104 seem to be reentrant (although it is documented to
105 be threadsafe...).
106 - fix Coro::Signal to bring back the original unreliable
107 but stateful semantics.
108 - fixed a lot of typos in Coro.pm (patch submitted by David
109 Steinbrunner, which applied flawlessly).
110
1113.6 Sat Apr 14 17:13:31 CEST 2007
112 - added some bugfixes to get eg/myhttpd working again.
113 - added Coro::Storable for often-cede'ing freeze/thaw.
114 - try to do a clean exit when a coroutine calls exit
115 (EXPERIMENTAL).
116 - got rid of indirect call through _coro_init.
117 - updated the partly antique examples in eg/ to
118 work again and be a bit less magic, too.
119 - fixed Coro::Signal semantics to work as documented again.
120
1213.55 Sun Mar 25 01:20:47 CET 2007
122 - add SAVE_DEFFH to save the default filehandle and enable
123 it by default.
124 - finally move socket-operations from Coro::Socket to Coro::Handle
125 to be able to unblock foreign sockets.
126 - add Coro::State::save_also and guarded_save.
127 - add count accessor to Coro::Semaphore.
128 - add Coro::State::cctx_stacksize.
129 - just for the fun of it, do not rely on implicit context,
130 which can dramatically improve performance, but people
131 using windows-process-emulation perls do not care much about
132 performance.
133
1343.51 Sun Mar 4 14:18:04 CET 2007
135 - fixed a problem when you weakened references to Coro::State's
136 (patch by Yuval Kogman).
137
1383.501 Wed Feb 28 12:44:07 CET 2007
139 - rename some global symbols as macosx from hell redefines
140 them without asking.
141
1423.5 Tue Feb 13 20:22:53 CET 2007
143 - do AnyEvent model detection earlier, avoiding problems
144 caused by first using AnyEvent and later Coro::Event.
145 - implement and document Coro::Event event objects.
146 - fix a potential problem in Coro::Event causing crashes.
147 - initialise PL_comppad when creating a new coroutine,
148 avoids crashes on early coro destruction.
149
1503.41 Mon Jan 22 19:19:49 CET 2007
151 - readline on Coro::Handle did not support undefined $/,
152 nor did it deliver partial lines on EOF or error.
153 - implement malloc fallback for stack allocation because
154 stupid broken idiotic OSX has a stupid broken
155 idiotic fits-the-whole-os mmap "implementation" and
156 my dick feels longer if Coro is portable even to
157 obsolete platforms.
158
1593.4 Fri Jan 19 21:52:54 CET 2007
160 - remove t/09_timer.t, as it isn't really testing much
161 but was rather flaky in practise.
162 - async_pool coro would keep arguments and callback alive until
163 it was reused.
164 - cancellation of a coroutine could cause spurious idle calls
165 in cede_notself.
166
1673.3 Sat Jan 6 03:45:00 CET 2007
7 - implement $coro->on_destroy. 168 - implement $coro->on_destroy.

12 - fixed an assert ("... == prev__cctx->idle_te") 173 - fixed an assert ("... == prev__cctx->idle_te")
13 that could errronously trigger. 174 that could errronously trigger.
14 - fix various large and small memleaks. 175 - fix various large and small memleaks.
15 - use a (hopefully) more stable cancel implementation 176 - use a (hopefully) more stable cancel implementation
16 that immediately frees the coroutine data. 177 that immediately frees the coroutine data.
178 - cede/cede_notself return a status now.
17 - added Coro::guard function. 179 - added Coro::guard function.
18 - added a global coroutine pool for jobs (on my machine, 180 - added a global coroutine pool for jobs (on my machine,
19 I can create and execute 48k simple coros/s with async, 181 I can create and execute 48k simple coros/s with async,
20 and 128k coros with async_pool). 182 and 128k coros with async_pool).
183 - Coro::AIO now uses the coroutine priority as io priority.
21 184
