30.95 Fri Dec 12 20:50:57 CET 2003 3TODO: better (earlier) error messages on broken transfer's
4TODO: destroy gets only called on cancel: fix(?)
5
63.3
7 - implement $coro->on_destroy.
8 - Coro::Event blocking semantics have been changed,
9 documented and - hopefully - improved.
10 - fix nice adding, not subtracting, from priority.
11 - fix ->prio and api_is_ready (patch by Mark Hinds).
12 - fixed an assert ("... == prev__cctx->idle_te")
13 that could errronously trigger.
14 - fix various large and small memleaks.
15 - use a (hopefully) more stable cancel implementation
16 that immediately frees the coroutine data.
17 - added Coro::guard function.
18 - added a global coroutine pool for jobs (on my machine,
19 I can create and execute 48k simple coros/s with async,
20 and 128k coros with async_pool).
21
223.2 Fri Dec 22 05:07:09 CET 2006
23 - improve portability to slightly older perls.
24 - use cleaner coroutine destruction.
25 - simplify configuration for users.
26 - optionally (unrecommended) prefer perl functions over
27 their coro replacements.
28
293.11 Tue Dec 5 13:11:24 CET 2006
30 - fixed some bogus assert's, but as perl.h disables assert even
31 without NDEBUG (thank you very much), not too many people should
32 notice (that did include myself). Andreas König noticed, though :)
33 - do not save/restore PL_sortcxix on >= 5.9.x, it doesn't seem to have
34 it. Also noticed by Andreas König :)
35 - save/restore tainted status.
36 - verified to pass the testsuite on my 5.9.5.
37
383.1 Mon Dec 4 23:03:40 CET 2006
39 - INCOMPATIBLE CHANGE: $/ is now per-coroutine (but slow).
40 - incompatible change: transfer flags are now per-state.
41 - give a better error message on deadlock.
42 - document Coro::nready.
43 - enhanced testsuite.
44
453.01 Sun Dec 3 23:47:42 CET 2006
46 - forgot to include Coro::Timer.
47
483.0 Sun Dec 3 22:57:25 CET 2006
49 - the "FINALLY COMPLETELY STABLE" release (coming soon:
50 the "FAMOUS LAST WORDS" release).
51 - implement a new stack sharing algorithm, which uses a stack
52 pool (size currently hardcoded).
53 - make stack sharing mandatory (it no longer uses a heuristic).
54 - eval/die no longer cause weird problems under heavy use.
55 - Coro::Event could cause livelocks if it was used but
56 no Coro::Event watchers were used.
57 - Coro::Event now uses asynccheck as prepare does not
58 check for changed watchers.
59 - Coro::Event allows multiple waiting coros and will wake up one
60 per event.
61 - Coro::Event should be cleaner and more efficient now.
62 - new utility function Coro::unblock_sub.
63 - document the sad fact that Event is no longer reentrant.
64 - putting a coroutine into the ready queue twice could under
65 some circumstances lead to stack corruption.
66 - minor incompatibility: subclassing Coro::State is supported
67 directly now without going through a _coro_state member.
68 - state/coro switching is much faster now.
69 - very minor optimisations and code/documentation cleanup.
70 - avoid problems due to compiler inlining.
71 - removed timers from Coro::Timer -> use AnyEvent instead.
72 - replaced Coro::idle coroutine by (cleaner) idle handler.
73 - updated to newest libcoro.
74 - implement enhanced support for valgrind.
75 - implement is_ready and return value for ready.
76 - removed Coro::Cont, it was a misnomer (it's generators),
77 and it was somewhat annoying to get it right. Will come back
78 if somebody asks for it :)
79 - many ->wait methods and Coro::Event could return
80 spuriously without the event having happened.
81
822.5 Tue Nov 7 12:22:33 CET 2006
83 - made Coro::Util, Coro::Select, Coro::Handle and Coro::Socket
84 use AnyEvent, moved them to Coro/.
85 - added Coro::LWP which contains all the uglyness required to
86 make LWP non-blocking.
87 - should work with perl 5.9.x now (Andreas König made me do it).
88 - fixed another bug in Coro::Select when the timeout was undef.
89 - reuse PL_start_env for all coros, saves some memory per coroutine.
90 - manage PL_top_env differently, hopefully to avoid panic: top_env.
91 - timeout argument was not properly used in Coro::Socket.
92 - allow limited forms of subclassing in Coro::Handle/Coro::Socket.
93 - emulate undocumented(!) functionality of IO::Socket required
94 by LWP(!!).
95 - updated eg/lwp to work with newer lwp's.
96 - remove "FATAL: uncaught exception" prefix. Coroutines that die
97 kill the whole process, just as exceptions in the main "coroutine"
98 did already.
99
1002.1 Wed Nov 1 23:01:13 CET 2006
101 - fix a long-standing bug in Coro::Select where select with
102 zero timeout would instead change the current default filehandle.
103 - use a simpler and hopefully more robust way to clone padlists
104 (uses less memory and a perl function instead of our own).
105 - coro can now create a stack guard area on many architectures.
106 - Coro::AIO properly reexports additional functions from IO::AIO.
107 - updated libcoro with a workaround for OS X,
108 pach and testing by Michael Schwern.
109
1102.0 Tue Oct 24 05:47:17 CEST 2006
111 - support additional aio requests in Coro::AIO.
112
1131.9 (never properly released due to a glitch)
114
1151.8 Thu Feb 2 00:59:06 CET 2006
116 - applied suggested patch by SAMV to avoid problems during stupid
117 mark & sweep gc run.
118 - applied patch by Scott Walters for 5.9.3 compatibility.
119
1201.7 Tue Dec 27 01:41:58 CET 2005
121 - added Coro::AIO, a thin wrapper around IO::AIO.
122 - improved Makefile.PL explanations.
123
1241.6 Mon Dec 12 21:30:05 CET 2005
125 - additionally save PM_curpm might fix as-of-yet
126 unseen problems with regex matches being attributed to the
127 wrong package.
128 - add t/10_bugs.t, which currently checks against imho broken
129 perls that use 0.26MB of stack space per Perl_magic_get
130 invocation (newer linuxes) as opposed to the 0.0002MB perl
131 normally uses.
132 - make stacksize configurable for the ultimate debian experience.
133
1341.51 Mon Dec 12 18:48:36 CET 2005
135 - remove debugging warn() accidentally left in Coro::Select.
136
1371.5 Tue Nov 29 13:32:44 CET 2005
138 - use Coro::Event inside Coro::Select to avoid spurious deadlocks.
139 - fix Coro::Select 'select'.
140 - strict'ify some modules.
141 - libcoro errornously restored the SIGUSR2 handler to SIGUSR1.
142 - use XSLoader in selected modules.
143 - remove some 5.6 compatibility cruft.
144
1451.4 Tue Sep 6 00:11:05 CEST 2005
146 - libcoro did not take into account the trampoline on amd64,
147 when 'l'inux method was used.
148
1491.31 Tue Aug 30 23:31:33 CEST 2005
150 - some portability fixes/workarounds.
151
1521.3 Sat Aug 20 03:08:56 CEST 2005
153 - no code changes. module seems to work fine.
154 - improve Coro::State docs, remove reference to nonexisting
155 Coro::State::flush method.
156 - no longer autodetect windows, present it as an option instead.
157
1581.2 Mon May 16 02:00:55 CEST 2005
159 - included libcoro.c earlier in State.xs, might improve portability.
160 - use a faster and possibly more stable Coro::Cont implementation.
161 - accept x86_64 in addition to amd64 for optimized linux-amd64 support.
162 - fix bugs Coro::SemaphoreSet that could cause locks never to be freed.
163 - fix bugs in CoroAPI.h and document it in Coro::MakeMaker.
164
1651.11 Thu Mar 3 18:00:52 CET 2005
166 - change of contact address.
167
1681.1 Tue Feb 22 20:51:16 CET 2005
169 - support [l]inux method on amd64.
170 - allow some context switches while compiling/eval'ing.
171
1721.0 Tue Aug 10 03:47:27 CEST 2004
173 - Event 0.89 fixes the bug again.
174 - fix the remaining(??) memleak. I didn't free the cache-AV for
175 padlists, so one AV per created anon-sub leaked.
176
1770.97 Fri May 14 15:23:32 CEST 2004
178 - remove stupid gcc extension that was an experiment only anyway.
179
1800.96 Thu May 13 18:09:29 CEST 2004
181 - tell people if they have yet another broken Event variant.
182 - made Coro to work _better_ with threads (it seems that, as long
183 as you use Coros in one thread only everything will work fine.
184 Looking at the perl source the problem might be missing locking
185 between Coro and some perl internal routines. That's not easily
186 fixable).
187 - (hopefully) got rid of the static xnext inside transfer.
188
1890.95 Sun Feb 15 03:20:28 CET 2004
