2 2
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)).

63.3 84.1
9 - incompatible change: $SIG{__DIE__} and $SIG{__WARN__} will now
10 be local to each coro (see Coro::State).
11 - possibly bring back 5.10 compatibility (untested).
12 - work around stupid (and wrong) warning on 5.10 :(.
13 - overlay the saved state over the context stack. This saves
14 a few hundred bytes per coroutine on average and also
15 speeds up context switching a bit.
16 - further tune default stack sizes.
17 - (more) correctly calculate stack usage in coro_rss.
18 - Coro::Storable::blocking_* did not properly lock
19 resulting in races between coroutines.
20 - added Coro::Storable::guard.
21 - stopping to trace a coroutine could destroy the cctx of
22 an unrelated coroutine.
23
244.03 Sat Oct 6 21:24:00 CEST 2007
25 - added Coro::throw method.
26 - minor code cleanups.
27
284.02 Sat Oct 6 02:36:47 CEST 2007
29 - fix a very minor per-coroutine memleak (a single codereference).
30 - fixed a bug where the currently in-use c context would be freed
31 prematurely (can happen only when programs change the stacksize
32 or use tracing).
33 - tracing can no longer keep a coro alive after it terminated.
34 - do static branch prediction in the common path for gcc. gives
35 about 2-5% speed improvement here.
36
374.01 Fri Oct 5 22:10:49 CEST 2007
38 - instead of recreating *a* standard output handle we simply
39 use STDOUT, which is faster and hopefully more robust.
40
414.0 Fri Oct 5 12:56:00 CEST 2007
42 - incompatibly changed Coro::Storable::freeze.
43 - major new feature: added Coro::Debug, for interactive coroutine
44 debugging, tracing and much more.
45 - major bug fix: unbelievable, but true: $_, $/ and many other
46 "saved" variables actually weren't being saved. This has been fixed,
47 of course, while increasing performance while losing all the save
48 flags.
49 - save flags are gone, and all the api functions dealing with them.
50 - added Coro::Semaphore::adjust.
51 - added Coro::Util::fork_eval.
52 - added Coro::Storable::{nfreeze,blocking_{freeze,nfreeze}}.
53 - added Coro::killall.
54 - reduce initial stack sizes to allow for "micro-coroutines".
55 - better async_pool resource management, moved parts of async_pool
56 handling to XS (major speed improvement).
57 - actually croak before modifying important data structures.
58 - refuse to transfer while compiling.
59 - possibly support eval EXPR better now.
60 - enable assembly per default on linux+bsd x86+amd64.
61 - all internal members were renamed _something for easier subclassing.
62 - many minor tweaks.
63
643.63 Wed May 16 14:10:06 CEST 2007
65 - implement handcoded assembly for x86/amd64 SVR ABI.
66
673.62 Fri Apr 27 21:36:06 CEST 2007
68 - upgrade libcoro (which might set unwind info correctly).
69 - change default on linux to setjmp/longjmp.
70
713.61 Thu Apr 19 12:36:18 CEST 2007
72 - Coro::Storable caused an endless loop when thawing invalid
73 pst's sometimes.
74 - use a Semaphore in Coro::Storable, as Storable doesn't
75 seem to be reentrant (although it is documented to
76 be threadsafe...).
77 - fix Coro::Signal to bring back the original unreliable
78 but stateful semantics.
79 - fixed a lot of typos in Coro.pm (patch submitted by David
80 Steinbrunner, which applied flawlessly).
81
823.6 Sat Apr 14 17:13:31 CEST 2007
83 - added some bugfixes to get eg/myhttpd working again.
84 - added Coro::Storable for often-cede'ing freeze/thaw.
85 - try to do a clean exit when a coroutine calls exit
86 (EXPERIMENTAL).
87 - got rid of indirect call through _coro_init.
88 - updated the partly antique examples in eg/ to
89 work again and be a bit less magic, too.
90 - fixed Coro::Signal semantics to work as documented again.
91
923.55 Sun Mar 25 01:20:47 CET 2007
93 - add SAVE_DEFFH to save the default filehandle and enable
94 it by default.
95 - finally move socket-operations from Coro::Socket to Coro::Handle
96 to be able to unblock foreign sockets.
97 - add Coro::State::save_also and guarded_save.
98 - add count accessor to Coro::Semaphore.
99 - add Coro::State::cctx_stacksize.
100 - just for the fun of it, do not rely on implicit context,
101 which can dramatically improve performance, but people
102 using windows-process-emulation perls do not care much about
103 performance.
104
1053.51 Sun Mar 4 14:18:04 CET 2007
106 - fixed a problem when you weakened references to Coro::State's
107 (patch by Yuval Kogman).
108
1093.501 Wed Feb 28 12:44:07 CET 2007
110 - rename some global symbols as macosx from hell redefines
111 them without asking.
112
1133.5 Tue Feb 13 20:22:53 CET 2007
114 - do AnyEvent model detection earlier, avoiding problems
115 caused by first using AnyEvent and later Coro::Event.
116 - implement and document Coro::Event event objects.
117 - fix a potential problem in Coro::Event causing crashes.
118 - initialise PL_comppad when creating a new coroutine,
119 avoids crashes on early coro destruction.
120
1213.41 Mon Jan 22 19:19:49 CET 2007
122 - readline on Coro::Handle did not support undefined $/,
123 nor did it deliver partial lines on EOF or error.
124 - implement malloc fallback for stack allocation because
125 stupid broken idiotic OSX has a stupid broken
126 idiotic fits-the-whole-os mmap "implementation" and
127 my dick feels longer if Coro is portable even to
128 obsolete platforms.
129
1303.4 Fri Jan 19 21:52:54 CET 2007
131 - remove t/09_timer.t, as it isn't really testing much
132 but was rather flaky in practise.
133 - async_pool coro would keep arguments and callback alive until
134 it was reused.
135 - cancellation of a coroutine could cause spurious idle calls
136 in cede_notself.
137
1383.3 Sat Jan 6 03:45:00 CET 2007
7 - implement $coro->on_destroy. 139 - implement $coro->on_destroy.

9 documented and - hopefully - improved. 141 documented and - hopefully - improved.
10 - fix nice adding, not subtracting, from priority. 142 - fix nice adding, not subtracting, from priority.
11 - fix ->prio and api_is_ready (patch by Mark Hinds). 143 - fix ->prio and api_is_ready (patch by Mark Hinds).
12 - fixed an assert ("... == prev__cctx->idle_te") 144 - fixed an assert ("... == prev__cctx->idle_te")
13 that could errronously trigger. 145 that could errronously trigger.
14 - fix various large and small memleaks. 146 - fix various large and small memleaks.
15 - use a (hopefully) more stable cancel implementation 147 - use a (hopefully) more stable cancel implementation
16 that immediately frees the coroutine data. 148 that immediately frees the coroutine data.
149 - cede/cede_notself return a status now.
17 - added Coro::guard function. 150 - added Coro::guard function.
151 - added a global coroutine pool for jobs (on my machine,
152 I can create and execute 48k simple coros/s with async,
153 and 128k coros with async_pool).
154 - Coro::AIO now uses the coroutine priority as io priority.

193.2 Fri Dec 22 05:07:09 CET 2006 1563.2 Fri Dec 22 05:07:09 CET 2006
