2 2
31.8 3TODO: better (earlier) error messages on broken transfer's
4TODO: destroy gets only called on cancel: fix(?)
5TODO: should explore PerlIO::via::CoroCede and PerlIO::via::CoroAIO.
6TODO: maybe implement a default message channel, very much like Erlang
7 (which is cool in a lot of important aspects (failures!),
8 but very lacking in others).

103.7
11 - added Coro::Debug, interactive coroutine debugging.
12 - added Coro::Semaphore::adjust.
13 - added Coro::Util::fork_eval.
14 - incompatibly changed Coro::Storable::freeze.
15 - added Coro::Storable::{nfreeze,blocking_{freeze,nfreeze}}.
16 - reduce initial stack sizes to allow for "micro-coroutines".
17 - many minor tweaks.
18
193.63 Wed May 16 14:10:06 CEST 2007
20 - implement handcoded assembly for x86/amd64 SVR ABI.
21
223.62 Fri Apr 27 21:36:06 CEST 2007
23 - upgrade libcoro (which might set unwind info correctly).
24 - change default on linux to setjmp/longjmp.
25
263.61 Thu Apr 19 12:36:18 CEST 2007
27 - Coro::Storable caused an endless loop when thawing invalid
28 pst's sometimes.
29 - use a Semaphore in Coro::Storable, as Storable doesn't
30 seem to be reentrant (although it is documented to
31 be threadsafe...).
32 - fix Coro::Signal to bring back the original unreliable
33 but stateful semantics.
34 - fixed a lot of typos in Coro.pm (patch submitted by David
35 Steinbrunner, which applied flawlessly).
36
373.6 Sat Apr 14 17:13:31 CEST 2007
38 - added some bugfixes to get eg/myhttpd working again.
39 - added Coro::Storable for often-cede'ing freeze/thaw.
40 - try to do a clean exit when a coroutine calls exit
41 (EXPERIMENTAL).
42 - got rid of indirect call through _coro_init.
43 - updated the partly antique examples in eg/ to
44 work again and be a bit less magic, too.
45 - fixed Coro::Signal semantics to work as documented again.
46
473.55 Sun Mar 25 01:20:47 CET 2007
48 - add SAVE_DEFFH to save the default filehandle and enable
49 it by default.
50 - finally move socket-operations from Coro::Socket to Coro::Handle
51 to be able to unblock foreign sockets.
52 - add Coro::State::save_also and guarded_save.
53 - add count accessor to Coro::Semaphore.
54 - add Coro::State::cctx_stacksize.
55 - just for the fun of it, do not rely on implicit context,
56 which can dramatically improve performance, but people
57 using windows-process-emulation perls do not care much about
58 performance.
59
603.51 Sun Mar 4 14:18:04 CET 2007
61 - fixed a problem when you weakened references to Coro::State's
62 (patch by Yuval Kogman).
63
643.501 Wed Feb 28 12:44:07 CET 2007
65 - rename some global symbols as macosx from hell redefines
66 them without asking.
67
683.5 Tue Feb 13 20:22:53 CET 2007
69 - do AnyEvent model detection earlier, avoiding problems
70 caused by first using AnyEvent and later Coro::Event.
71 - implement and document Coro::Event event objects.
72 - fix a potential problem in Coro::Event causing crashes.
73 - initialise PL_comppad when creating a new coroutine,
74 avoids crashes on early coro destruction.
75
763.41 Mon Jan 22 19:19:49 CET 2007
77 - readline on Coro::Handle did not support undefined $/,
78 nor did it deliver partial lines on EOF or error.
79 - implement malloc fallback for stack allocation because
80 stupid broken idiotic OSX has a stupid broken
81 idiotic fits-the-whole-os mmap "implementation" and
82 my dick feels longer if Coro is portable even to
83 obsolete platforms.
84
853.4 Fri Jan 19 21:52:54 CET 2007
86 - remove t/09_timer.t, as it isn't really testing much
87 but was rather flaky in practise.
88 - async_pool coro would keep arguments and callback alive until
89 it was reused.
90 - cancellation of a coroutine could cause spurious idle calls
91 in cede_notself.
92
933.3 Sat Jan 6 03:45:00 CET 2007
94 - implement $coro->on_destroy.
95 - Coro::Event blocking semantics have been changed,
96 documented and - hopefully - improved.
97 - fix nice adding, not subtracting, from priority.
98 - fix ->prio and api_is_ready (patch by Mark Hinds).
99 - fixed an assert ("... == prev__cctx->idle_te")
100 that could errronously trigger.
101 - fix various large and small memleaks.
102 - use a (hopefully) more stable cancel implementation
103 that immediately frees the coroutine data.
104 - cede/cede_notself return a status now.
105 - added Coro::guard function.
106 - added a global coroutine pool for jobs (on my machine,
107 I can create and execute 48k simple coros/s with async,
108 and 128k coros with async_pool).
109 - Coro::AIO now uses the coroutine priority as io priority.
110
1113.2 Fri Dec 22 05:07:09 CET 2006
112 - improve portability to slightly older perls.
113 - use cleaner coroutine destruction.
114 - simplify configuration for users.
115 - optionally (unrecommended) prefer perl functions over
116 their coro replacements.
117
1183.11 Tue Dec 5 13:11:24 CET 2006
119 - fixed some bogus assert's, but as perl.h disables assert even
120 without NDEBUG (thank you very much), not too many people should
121 notice (that did include myself). Andreas König noticed, though :)
122 - do not save/restore PL_sortcxix on >= 5.9.x, it doesn't seem to have
123 it. Also noticed by Andreas König :)
124 - save/restore tainted status.
125 - verified to pass the testsuite on my 5.9.5.
126
1273.1 Mon Dec 4 23:03:40 CET 2006
128 - INCOMPATIBLE CHANGE: $/ is now per-coroutine (but slow).
129 - incompatible change: transfer flags are now per-state.
130 - give a better error message on deadlock.
131 - document Coro::nready.
132 - enhanced testsuite.
133
1343.01 Sun Dec 3 23:47:42 CET 2006
135 - forgot to include Coro::Timer.
136
1373.0 Sun Dec 3 22:57:25 CET 2006
138 - the "FINALLY COMPLETELY STABLE" release (coming soon:
139 the "FAMOUS LAST WORDS" release).
140 - implement a new stack sharing algorithm, which uses a stack
141 pool (size currently hardcoded).
142 - make stack sharing mandatory (it no longer uses a heuristic).
143 - eval/die no longer cause weird problems under heavy use.
144 - Coro::Event could cause livelocks if it was used but
145 no Coro::Event watchers were used.
146 - Coro::Event now uses asynccheck as prepare does not
147 check for changed watchers.
148 - Coro::Event allows multiple waiting coros and will wake up one
149 per event.
150 - Coro::Event should be cleaner and more efficient now.
151 - new utility function Coro::unblock_sub.
152 - document the sad fact that Event is no longer reentrant.
153 - putting a coroutine into the ready queue twice could under
154 some circumstances lead to stack corruption.
155 - minor incompatibility: subclassing Coro::State is supported
156 directly now without going through a _coro_state member.
157 - state/coro switching is much faster now.
158 - very minor optimisations and code/documentation cleanup.
159 - avoid problems due to compiler inlining.
160 - removed timers from Coro::Timer -> use AnyEvent instead.
161 - replaced Coro::idle coroutine by (cleaner) idle handler.
162 - updated to newest libcoro.
163 - implement enhanced support for valgrind.
164 - implement is_ready and return value for ready.
165 - removed Coro::Cont, it was a misnomer (it's generators),
166 and it was somewhat annoying to get it right. Will come back
167 if somebody asks for it :)
168 - many ->wait methods and Coro::Event could return
169 spuriously without the event having happened.
170
1712.5 Tue Nov 7 12:22:33 CET 2006
172 - made Coro::Util, Coro::Select, Coro::Handle and Coro::Socket
173 use AnyEvent, moved them to Coro/.
174 - added Coro::LWP which contains all the uglyness required to
175 make LWP non-blocking.
176 - should work with perl 5.9.x now (Andreas König made me do it).
177 - fixed another bug in Coro::Select when the timeout was undef.
178 - reuse PL_start_env for all coros, saves some memory per coroutine.
179 - manage PL_top_env differently, hopefully to avoid panic: top_env.
180 - timeout argument was not properly used in Coro::Socket.
181 - allow limited forms of subclassing in Coro::Handle/Coro::Socket.
182 - emulate undocumented(!) functionality of IO::Socket required
183 by LWP(!!).
184 - updated eg/lwp to work with newer lwp's.
185 - remove "FATAL: uncaught exception" prefix. Coroutines that die
186 kill the whole process, just as exceptions in the main "coroutine"
187 did already.
188
1892.1 Wed Nov 1 23:01:13 CET 2006
190 - fix a long-standing bug in Coro::Select where select with
191 zero timeout would instead change the current default filehandle.
192 - use a simpler and hopefully more robust way to clone padlists
193 (uses less memory and a perl function instead of our own).
194 - coro can now create a stack guard area on many architectures.
195 - Coro::AIO properly reexports additional functions from IO::AIO.
196 - updated libcoro with a workaround for OS X,
197 pach and testing by Michael Schwern.
198
1992.0 Tue Oct 24 05:47:17 CEST 2006
200 - support additional aio requests in Coro::AIO.
201
2021.9 (never properly released due to a glitch)

5 mark & sweep gc run. 206 mark & sweep gc run.
6 - applied patch by Scott Walters for 5.9.3 compatibility. 207 - applied patch by Scott Walters for 5.9.3 compatibility.
