1Revision history for Perl extension Coro. 1Revision history for Perl extension Coro.
2 2
3TODO: check wether stack-sharing is still effective 3TODO: better (earlier) error messages on broken transfer's
4TODO: more effective stack sharing by having one "default stack" for "simple" coroutines? 4TODO: destroy gets only called on cancel: fix(?)
5TODO: verify exception frame changes and force stack copies? 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 - incompatibly changed Coro::Storable::freeze.
12 - added Coro::Debug, interactive coroutine debugging.
13 - added Coro::Semaphore::adjust.
14 - added Coro::Util::fork_eval.
15 - added Coro::Storable::{nfreeze,blocking_{freeze,nfreeze}}.
16 - reduce initial stack sizes to allow for "micro-coroutines".
17 - better async_pool resource management, moved parts of async_pool
18 handling to XS.
19 - many minor tweaks.
20
213.63 Wed May 16 14:10:06 CEST 2007
22 - implement handcoded assembly for x86/amd64 SVR ABI.
23
243.62 Fri Apr 27 21:36:06 CEST 2007
25 - upgrade libcoro (which might set unwind info correctly).
26 - change default on linux to setjmp/longjmp.
27
283.61 Thu Apr 19 12:36:18 CEST 2007
29 - Coro::Storable caused an endless loop when thawing invalid
30 pst's sometimes.
31 - use a Semaphore in Coro::Storable, as Storable doesn't
32 seem to be reentrant (although it is documented to
33 be threadsafe...).
34 - fix Coro::Signal to bring back the original unreliable
35 but stateful semantics.
36 - fixed a lot of typos in Coro.pm (patch submitted by David
37 Steinbrunner, which applied flawlessly).
38
393.6 Sat Apr 14 17:13:31 CEST 2007
40 - added some bugfixes to get eg/myhttpd working again.
41 - added Coro::Storable for often-cede'ing freeze/thaw.
42 - try to do a clean exit when a coroutine calls exit
43 (EXPERIMENTAL).
44 - got rid of indirect call through _coro_init.
45 - updated the partly antique examples in eg/ to
46 work again and be a bit less magic, too.
47 - fixed Coro::Signal semantics to work as documented again.
48
493.55 Sun Mar 25 01:20:47 CET 2007
50 - add SAVE_DEFFH to save the default filehandle and enable
51 it by default.
52 - finally move socket-operations from Coro::Socket to Coro::Handle
53 to be able to unblock foreign sockets.
54 - add Coro::State::save_also and guarded_save.
55 - add count accessor to Coro::Semaphore.
56 - add Coro::State::cctx_stacksize.
57 - just for the fun of it, do not rely on implicit context,
58 which can dramatically improve performance, but people
59 using windows-process-emulation perls do not care much about
60 performance.
61
623.51 Sun Mar 4 14:18:04 CET 2007
63 - fixed a problem when you weakened references to Coro::State's
64 (patch by Yuval Kogman).
65
663.501 Wed Feb 28 12:44:07 CET 2007
67 - rename some global symbols as macosx from hell redefines
68 them without asking.
69
703.5 Tue Feb 13 20:22:53 CET 2007
71 - do AnyEvent model detection earlier, avoiding problems
72 caused by first using AnyEvent and later Coro::Event.
73 - implement and document Coro::Event event objects.
74 - fix a potential problem in Coro::Event causing crashes.
75 - initialise PL_comppad when creating a new coroutine,
76 avoids crashes on early coro destruction.
77
783.41 Mon Jan 22 19:19:49 CET 2007
79 - readline on Coro::Handle did not support undefined $/,
80 nor did it deliver partial lines on EOF or error.
81 - implement malloc fallback for stack allocation because
82 stupid broken idiotic OSX has a stupid broken
83 idiotic fits-the-whole-os mmap "implementation" and
84 my dick feels longer if Coro is portable even to
85 obsolete platforms.
86
873.4 Fri Jan 19 21:52:54 CET 2007
88 - remove t/09_timer.t, as it isn't really testing much
89 but was rather flaky in practise.
90 - async_pool coro would keep arguments and callback alive until
91 it was reused.
92 - cancellation of a coroutine could cause spurious idle calls
93 in cede_notself.
94
953.3 Sat Jan 6 03:45:00 CET 2007
96 - implement $coro->on_destroy.
97 - Coro::Event blocking semantics have been changed,
98 documented and - hopefully - improved.
99 - fix nice adding, not subtracting, from priority.
100 - fix ->prio and api_is_ready (patch by Mark Hinds).
101 - fixed an assert ("... == prev__cctx->idle_te")
102 that could errronously trigger.
103 - fix various large and small memleaks.
104 - use a (hopefully) more stable cancel implementation
105 that immediately frees the coroutine data.
106 - cede/cede_notself return a status now.
107 - added Coro::guard function.
108 - added a global coroutine pool for jobs (on my machine,
109 I can create and execute 48k simple coros/s with async,
110 and 128k coros with async_pool).
111 - Coro::AIO now uses the coroutine priority as io priority.
112
1133.2 Fri Dec 22 05:07:09 CET 2006
114 - improve portability to slightly older perls.
115 - use cleaner coroutine destruction.
116 - simplify configuration for users.
117 - optionally (unrecommended) prefer perl functions over
118 their coro replacements.
119
1203.11 Tue Dec 5 13:11:24 CET 2006
121 - fixed some bogus assert's, but as perl.h disables assert even
122 without NDEBUG (thank you very much), not too many people should
123 notice (that did include myself). Andreas König noticed, though :)
124 - do not save/restore PL_sortcxix on >= 5.9.x, it doesn't seem to have
125 it. Also noticed by Andreas König :)
126 - save/restore tainted status.
127 - verified to pass the testsuite on my 5.9.5.
128
1293.1 Mon Dec 4 23:03:40 CET 2006
130 - INCOMPATIBLE CHANGE: $/ is now per-coroutine (but slow).
131 - incompatible change: transfer flags are now per-state.
132 - give a better error message on deadlock.
133 - document Coro::nready.
134 - enhanced testsuite.
135
1363.01 Sun Dec 3 23:47:42 CET 2006
137 - forgot to include Coro::Timer.
138
1393.0 Sun Dec 3 22:57:25 CET 2006
140 - the "FINALLY COMPLETELY STABLE" release (coming soon:
141 the "FAMOUS LAST WORDS" release).
142 - implement a new stack sharing algorithm, which uses a stack
143 pool (size currently hardcoded).
144 - make stack sharing mandatory (it no longer uses a heuristic).
145 - eval/die no longer cause weird problems under heavy use.
7 - Coro::Event could cause livelocks if it was used but 146 - Coro::Event could cause livelocks if it was used but
8 Event watchers were used directly. 147 no Coro::Event watchers were used.
148 - Coro::Event now uses asynccheck as prepare does not
149 check for changed watchers.
150 - Coro::Event allows multiple waiting coros and will wake up one
151 per event.
9 - Coro::Event should be cleaner and more efficient now. 152 - Coro::Event should be cleaner and more efficient now.
10 - minor documentation cleanup. 153 - new utility function Coro::unblock_sub.
154 - document the sad fact that Event is no longer reentrant.
155 - putting a coroutine into the ready queue twice could under
156 some circumstances lead to stack corruption.
157 - minor incompatibility: subclassing Coro::State is supported
158 directly now without going through a _coro_state member.
159 - state/coro switching is much faster now.
11 - very minor optimisations and cleanups. 160 - very minor optimisations and code/documentation cleanup.
12 - avoid problems due to compiler inlining. 161 - avoid problems due to compiler inlining.
162 - removed timers from Coro::Timer -> use AnyEvent instead.
163 - replaced Coro::idle coroutine by (cleaner) idle handler.
164 - updated to newest libcoro.
165 - implement enhanced support for valgrind.
166 - implement is_ready and return value for ready.
167 - removed Coro::Cont, it was a misnomer (it's generators),
168 and it was somewhat annoying to get it right. Will come back
169 if somebody asks for it :)
170 - many ->wait methods and Coro::Event could return
171 spuriously without the event having happened.

142.5 Tue Nov 7 12:22:33 CET 2006 1732.5 Tue Nov 7 12:22:33 CET 2006
15 - made Coro::Util, Coro::Select, Coro::Handle and Coro::Socket 174 - made Coro::Util, Coro::Select, Coro::Handle and Coro::Socket
16 use AnyEvent, moved them to Coro/. 175 use AnyEvent, moved them to Coro/.
17 - added Coro::LWP which contains all the uglyness required to 176 - added Coro::LWP which contains all the uglyness required to
