2 2
3TODO: check wether stack-sharing is still effective 3TODO: destroy gets only called on cancel: fix(?)
4TODO: more effective stack sharing by having one "default stack" for "simple" coroutines? 4TODO: should explore PerlIO::via::CoroCede and PerlIO::via::CoroAIO.
5TODO: verify exception frame changes and force stack copies? 5TODO: maybe implement a default message channel, very much like Erlang
6 (which is cool in a lot of important aspects (failures!),
7 but very lacking in others (higher level ipc)).

93.8
10 - incompatibly changed Coro::Storable::freeze.
11 - major new feature: added Coro::Debug, for interactive coroutine
12 debugging, tracing and much more.
13 - added Coro::Semaphore::adjust.
14 - added Coro::Util::fork_eval.
15 - added Coro::Storable::{nfreeze,blocking_{freeze,nfreeze}}.
16 - added Coro::killall.
17 - reduce initial stack sizes to allow for "micro-coroutines".
18 - better async_pool resource management, moved parts of async_pool
19 handling to XS (major speed improvement).
20 - actually croak before modifying important data structures.
21 - refuse to transfer while compiling.
22 - possibly support eval EXPR better now.
23 - enable assembly per default on linux+bsd x86+amd64.
24 - all internal members are named _something for easier subclassing.
25 - many minor tweaks.
26
273.63 Wed May 16 14:10:06 CEST 2007
28 - implement handcoded assembly for x86/amd64 SVR ABI.
29
303.62 Fri Apr 27 21:36:06 CEST 2007
31 - upgrade libcoro (which might set unwind info correctly).
32 - change default on linux to setjmp/longjmp.
33
343.61 Thu Apr 19 12:36:18 CEST 2007
35 - Coro::Storable caused an endless loop when thawing invalid
36 pst's sometimes.
37 - use a Semaphore in Coro::Storable, as Storable doesn't
38 seem to be reentrant (although it is documented to
39 be threadsafe...).
40 - fix Coro::Signal to bring back the original unreliable
41 but stateful semantics.
42 - fixed a lot of typos in Coro.pm (patch submitted by David
43 Steinbrunner, which applied flawlessly).
44
453.6 Sat Apr 14 17:13:31 CEST 2007
46 - added some bugfixes to get eg/myhttpd working again.
47 - added Coro::Storable for often-cede'ing freeze/thaw.
48 - try to do a clean exit when a coroutine calls exit
49 (EXPERIMENTAL).
50 - got rid of indirect call through _coro_init.
51 - updated the partly antique examples in eg/ to
52 work again and be a bit less magic, too.
53 - fixed Coro::Signal semantics to work as documented again.
54
553.55 Sun Mar 25 01:20:47 CET 2007
56 - add SAVE_DEFFH to save the default filehandle and enable
57 it by default.
58 - finally move socket-operations from Coro::Socket to Coro::Handle
59 to be able to unblock foreign sockets.
60 - add Coro::State::save_also and guarded_save.
61 - add count accessor to Coro::Semaphore.
62 - add Coro::State::cctx_stacksize.
63 - just for the fun of it, do not rely on implicit context,
64 which can dramatically improve performance, but people
65 using windows-process-emulation perls do not care much about
66 performance.
67
683.51 Sun Mar 4 14:18:04 CET 2007
69 - fixed a problem when you weakened references to Coro::State's
70 (patch by Yuval Kogman).
71
723.501 Wed Feb 28 12:44:07 CET 2007
73 - rename some global symbols as macosx from hell redefines
74 them without asking.
75
763.5 Tue Feb 13 20:22:53 CET 2007
77 - do AnyEvent model detection earlier, avoiding problems
78 caused by first using AnyEvent and later Coro::Event.
79 - implement and document Coro::Event event objects.
80 - fix a potential problem in Coro::Event causing crashes.
81 - initialise PL_comppad when creating a new coroutine,
82 avoids crashes on early coro destruction.
83
843.41 Mon Jan 22 19:19:49 CET 2007
85 - readline on Coro::Handle did not support undefined $/,
86 nor did it deliver partial lines on EOF or error.
87 - implement malloc fallback for stack allocation because
88 stupid broken idiotic OSX has a stupid broken
89 idiotic fits-the-whole-os mmap "implementation" and
90 my dick feels longer if Coro is portable even to
91 obsolete platforms.
92
933.4 Fri Jan 19 21:52:54 CET 2007
94 - remove t/09_timer.t, as it isn't really testing much
95 but was rather flaky in practise.
96 - async_pool coro would keep arguments and callback alive until
97 it was reused.
98 - cancellation of a coroutine could cause spurious idle calls
99 in cede_notself.
100
1013.3 Sat Jan 6 03:45:00 CET 2007
102 - implement $coro->on_destroy.
103 - Coro::Event blocking semantics have been changed,
104 documented and - hopefully - improved.
105 - fix nice adding, not subtracting, from priority.
106 - fix ->prio and api_is_ready (patch by Mark Hinds).
107 - fixed an assert ("... == prev__cctx->idle_te")
108 that could errronously trigger.
109 - fix various large and small memleaks.
110 - use a (hopefully) more stable cancel implementation
111 that immediately frees the coroutine data.
112 - cede/cede_notself return a status now.
113 - added Coro::guard function.
114 - added a global coroutine pool for jobs (on my machine,
115 I can create and execute 48k simple coros/s with async,
116 and 128k coros with async_pool).
117 - Coro::AIO now uses the coroutine priority as io priority.
118
1193.2 Fri Dec 22 05:07:09 CET 2006
120 - improve portability to slightly older perls.
121 - use cleaner coroutine destruction.
122 - simplify configuration for users.
123 - optionally (unrecommended) prefer perl functions over
124 their coro replacements.
125
1263.11 Tue Dec 5 13:11:24 CET 2006
127 - fixed some bogus assert's, but as perl.h disables assert even
128 without NDEBUG (thank you very much), not too many people should
129 notice (that did include myself). Andreas König noticed, though :)
130 - do not save/restore PL_sortcxix on >= 5.9.x, it doesn't seem to have
131 it. Also noticed by Andreas König :)
132 - save/restore tainted status.
133 - verified to pass the testsuite on my 5.9.5.
134
1353.1 Mon Dec 4 23:03:40 CET 2006
136 - INCOMPATIBLE CHANGE: $/ is now per-coroutine (but slow).
137 - incompatible change: transfer flags are now per-state.
138 - give a better error message on deadlock.
139 - document Coro::nready.
140 - enhanced testsuite.
141
1423.01 Sun Dec 3 23:47:42 CET 2006
143 - forgot to include Coro::Timer.
144
1453.0 Sun Dec 3 22:57:25 CET 2006
146 - the "FINALLY COMPLETELY STABLE" release (coming soon:
147 the "FAMOUS LAST WORDS" release).
7 - reimplement a new stack sharing algorithm. 148 - implement a new stack sharing algorithm, which uses a stack
149 pool (size currently hardcoded).
8 - make stack sharing mandatory (it no longer uses a heuristic). 150 - make stack sharing mandatory (it no longer uses a heuristic).
9 - eval/die no longer cause weird problems under heavy use. 151 - eval/die no longer cause weird problems under heavy use.
10 - Coro::Event could cause livelocks if it was used but 152 - Coro::Event could cause livelocks if it was used but
11 Event watchers were used directly. 153 no Coro::Event watchers were used.
154 - Coro::Event now uses asynccheck as prepare does not
155 check for changed watchers.
156 - Coro::Event allows multiple waiting coros and will wake up one
157 per event.
12 - Coro::Event should be cleaner and more efficient now. 158 - Coro::Event should be cleaner and more efficient now.
159 - new utility function Coro::unblock_sub.
160 - document the sad fact that Event is no longer reentrant.
161 - putting a coroutine into the ready queue twice could under
162 some circumstances lead to stack corruption.
13 - minor incompatibility: subclassing is supported directly now 163 - minor incompatibility: subclassing Coro::State is supported
14 without going through a _coro_state member. 164 directly now without going through a _coro_state member.
15 - state/coro switching is much faster now. 165 - state/coro switching is much faster now.
16 - very minor optimisations and code/documentation cleanup. 166 - very minor optimisations and code/documentation cleanup.
17 - avoid problems due to compiler inlining. 167 - avoid problems due to compiler inlining.
18 - removed timers from Coro::Timer -> use AnyEvent instead. 168 - removed timers from Coro::Timer -> use AnyEvent instead.
19 - replaced Coro::idle coroutine by (cleaner) idle handler. 169 - replaced Coro::idle coroutine by (cleaner) idle handler.
20 - updated to newest libcoro. 170 - updated to newest libcoro.
171 - implement enhanced support for valgrind.
172 - implement is_ready and return value for ready.
173 - removed Coro::Cont, it was a misnomer (it's generators),
174 and it was somewhat annoying to get it right. Will come back
175 if somebody asks for it :)
176 - many ->wait methods and Coro::Event could return
177 spuriously without the event having happened.

222.5 Tue Nov 7 12:22:33 CET 2006 1792.5 Tue Nov 7 12:22:33 CET 2006
23 - made Coro::Util, Coro::Select, Coro::Handle and Coro::Socket 180 - made Coro::Util, Coro::Select, Coro::Handle and Coro::Socket
24 use AnyEvent, moved them to Coro/. 181 use AnyEvent, moved them to Coro/.
25 - added Coro::LWP which contains all the uglyness required to 182 - added Coro::LWP which contains all the uglyness required to
