3TODO: better (earlier) error messages on broken transfer's
4TODO: destroy gets only called on cancel: fix(?)
5
6 - remove t/09_timer.t, as it isn't really testing much
7 but was rather flaky in practise.
8 - async_pool coro would keep arguments and callback alive until
9 it was reused.
10
113.3 Sat Jan 6 03:45:00 CET 2007
12 - implement $coro->on_destroy.
13 - Coro::Event blocking semantics have been changed,
14 documented and - hopefully - improved.
15 - fix nice adding, not subtracting, from priority.
16 - fix ->prio and api_is_ready (patch by Mark Hinds).
17 - fixed an assert ("... == prev__cctx->idle_te")
18 that could errronously trigger.
19 - fix various large and small memleaks.
20 - use a (hopefully) more stable cancel implementation
21 that immediately frees the coroutine data.
22 - cede/cede_notself return a status now.
23 - added Coro::guard function.
24 - added a global coroutine pool for jobs (on my machine,
25 I can create and execute 48k simple coros/s with async,
26 and 128k coros with async_pool).
27 - Coro::AIO now uses the coroutine priority as io priority.
28
293.2 Fri Dec 22 05:07:09 CET 2006
30 - improve portability to slightly older perls.
31 - use cleaner coroutine destruction.
32 - simplify configuration for users.
33 - optionally (unrecommended) prefer perl functions over
34 their coro replacements.
35
363.11 Tue Dec 5 13:11:24 CET 2006
37 - fixed some bogus assert's, but as perl.h disables assert even
38 without NDEBUG (thank you very much), not too many people should
39 notice (that did include myself). Andreas König noticed, though :)
40 - do not save/restore PL_sortcxix on >= 5.9.x, it doesn't seem to have
41 it. Also noticed by Andreas König :)
42 - save/restore tainted status.
43 - verified to pass the testsuite on my 5.9.5.
44
453.1 Mon Dec 4 23:03:40 CET 2006
46 - INCOMPATIBLE CHANGE: $/ is now per-coroutine (but slow).
47 - incompatible change: transfer flags are now per-state.
48 - give a better error message on deadlock.
49 - document Coro::nready.
50 - enhanced testsuite.
51
523.01 Sun Dec 3 23:47:42 CET 2006
53 - forgot to include Coro::Timer.
54
553.0 Sun Dec 3 22:57:25 CET 2006
56 - the "FINALLY COMPLETELY STABLE" release (coming soon:
57 the "FAMOUS LAST WORDS" release).
58 - implement a new stack sharing algorithm, which uses a stack
59 pool (size currently hardcoded).
60 - make stack sharing mandatory (it no longer uses a heuristic).
61 - eval/die no longer cause weird problems under heavy use.
62 - Coro::Event could cause livelocks if it was used but
63 no Coro::Event watchers were used.
64 - Coro::Event now uses asynccheck as prepare does not
65 check for changed watchers.
66 - Coro::Event allows multiple waiting coros and will wake up one
67 per event.
68 - Coro::Event should be cleaner and more efficient now.
69 - new utility function Coro::unblock_sub.
70 - document the sad fact that Event is no longer reentrant.
71 - putting a coroutine into the ready queue twice could under
72 some circumstances lead to stack corruption.
73 - minor incompatibility: subclassing Coro::State is supported
74 directly now without going through a _coro_state member.
75 - state/coro switching is much faster now.
76 - very minor optimisations and code/documentation cleanup.
77 - avoid problems due to compiler inlining.
78 - removed timers from Coro::Timer -> use AnyEvent instead.
79 - replaced Coro::idle coroutine by (cleaner) idle handler.
80 - updated to newest libcoro.
81 - implement enhanced support for valgrind.
82 - implement is_ready and return value for ready.
83 - removed Coro::Cont, it was a misnomer (it's generators),
84 and it was somewhat annoying to get it right. Will come back
85 if somebody asks for it :)
86 - many ->wait methods and Coro::Event could return
87 spuriously without the event having happened.
88
892.5 Tue Nov 7 12:22:33 CET 2006
90 - made Coro::Util, Coro::Select, Coro::Handle and Coro::Socket
91 use AnyEvent, moved them to Coro/.
92 - added Coro::LWP which contains all the uglyness required to
93 make LWP non-blocking.
94 - should work with perl 5.9.x now (Andreas König made me do it).
95 - fixed another bug in Coro::Select when the timeout was undef.
96 - reuse PL_start_env for all coros, saves some memory per coroutine.
97 - manage PL_top_env differently, hopefully to avoid panic: top_env.
98 - timeout argument was not properly used in Coro::Socket.
99 - allow limited forms of subclassing in Coro::Handle/Coro::Socket.
100 - emulate undocumented(!) functionality of IO::Socket required
101 by LWP(!!).
102 - updated eg/lwp to work with newer lwp's.
103 - remove "FATAL: uncaught exception" prefix. Coroutines that die
104 kill the whole process, just as exceptions in the main "coroutine"
105 did already.
106
1072.1 Wed Nov 1 23:01:13 CET 2006
108 - fix a long-standing bug in Coro::Select where select with
109 zero timeout would instead change the current default filehandle.
110 - use a simpler and hopefully more robust way to clone padlists
111 (uses less memory and a perl function instead of our own).
112 - coro can now create a stack guard area on many architectures.
113 - Coro::AIO properly reexports additional functions from IO::AIO.
114 - updated libcoro with a workaround for OS X,
115 pach and testing by Michael Schwern.
116
1172.0 Tue Oct 24 05:47:17 CEST 2006
118 - support additional aio requests in Coro::AIO.
119
1201.9 (never properly released due to a glitch)
121
1221.8 Thu Feb 2 00:59:06 CET 2006
123 - applied suggested patch by SAMV to avoid problems during stupid
124 mark & sweep gc run.
125 - applied patch by Scott Walters for 5.9.3 compatibility.
126
1271.7 Tue Dec 27 01:41:58 CET 2005
128 - added Coro::AIO, a thin wrapper around IO::AIO.
129 - improved Makefile.PL explanations.
130
1311.6 Mon Dec 12 21:30:05 CET 2005
132 - additionally save PM_curpm might fix as-of-yet
133 unseen problems with regex matches being attributed to the
134 wrong package.
135 - add t/10_bugs.t, which currently checks against imho broken
136 perls that use 0.26MB of stack space per Perl_magic_get
137 invocation (newer linuxes) as opposed to the 0.0002MB perl
138 normally uses.
139 - make stacksize configurable for the ultimate debian experience.
140
1411.51 Mon Dec 12 18:48:36 CET 2005
142 - remove debugging warn() accidentally left in Coro::Select.
143
1441.5 Tue Nov 29 13:32:44 CET 2005
145 - use Coro::Event inside Coro::Select to avoid spurious deadlocks.
146 - fix Coro::Select 'select'.
147 - strict'ify some modules.
148 - libcoro errornously restored the SIGUSR2 handler to SIGUSR1.
149 - use XSLoader in selected modules.
150 - remove some 5.6 compatibility cruft.
151
1521.4 Tue Sep 6 00:11:05 CEST 2005
153 - libcoro did not take into account the trampoline on amd64,
154 when 'l'inux method was used.
155
1561.31 Tue Aug 30 23:31:33 CEST 2005
157 - some portability fixes/workarounds.
158
1591.3 Sat Aug 20 03:08:56 CEST 2005
160 - no code changes. module seems to work fine.
161 - improve Coro::State docs, remove reference to nonexisting
162 Coro::State::flush method.
163 - no longer autodetect windows, present it as an option instead.
164
1651.2 Mon May 16 02:00:55 CEST 2005
166 - included libcoro.c earlier in State.xs, might improve portability.
167 - use a faster and possibly more stable Coro::Cont implementation.
168 - accept x86_64 in addition to amd64 for optimized linux-amd64 support.
169 - fix bugs Coro::SemaphoreSet that could cause locks never to be freed.
170 - fix bugs in CoroAPI.h and document it in Coro::MakeMaker.
171
1721.11 Thu Mar 3 18:00:52 CET 2005
