7 - give a better error message on deadlock.

93.01 Sun Dec 3 23:47:42 CET 2006
10 - forgot to include Coro::Timer.
11
123.0 Sun Dec 3 22:57:25 CET 2006
13 - the "FINALLY COMPLETELY STABLE" release (coming soon:
14 the "FAMOUS LAST WORDS" release).
15 - implement a new stack sharing algorithm, which uses a stack
16 pool (size currently hardcoded).
17 - make stack sharing mandatory (it no longer uses a heuristic).
18 - eval/die no longer cause weird problems under heavy use.
19 - Coro::Event could cause livelocks if it was used but
20 no Coro::Event watchers were used.
21 - Coro::Event now uses asynccheck as prepare does not
22 check for changed watchers.
23 - Coro::Event allows multiple waiting coros and will wake up one
24 per event.
25 - Coro::Event should be cleaner and more efficient now.
26 - new utility function Coro::unblock_sub.
27 - document the sad fact that Event is no longer reentrant.
28 - putting a coroutine into the ready queue twice could under
29 some circumstances lead to stack corruption.
30 - minor incompatibility: subclassing Coro::State is supported
31 directly now without going through a _coro_state member.
32 - state/coro switching is much faster now.
33 - very minor optimisations and code/documentation cleanup.
34 - avoid problems due to compiler inlining.
35 - removed timers from Coro::Timer -> use AnyEvent instead.
36 - replaced Coro::idle coroutine by (cleaner) idle handler.
37 - updated to newest libcoro.
38 - implement enhanced support for valgrind.
39 - implement is_ready and return value for ready.
40 - removed Coro::Cont, it was a misnomer (it's generators),
41 and it was somewhat annoying to get it right. Will come back
42 if somebody asks for it :)
43 - many ->wait methods and Coro::Event could return
44 spuriously without the event having happened.
45
462.5 Tue Nov 7 12:22:33 CET 2006
47 - made Coro::Util, Coro::Select, Coro::Handle and Coro::Socket
48 use AnyEvent, moved them to Coro/.
49 - added Coro::LWP which contains all the uglyness required to
50 make LWP non-blocking.
51 - should work with perl 5.9.x now (Andreas König made me do it).
52 - fixed another bug in Coro::Select when the timeout was undef.
53 - reuse PL_start_env for all coros, saves some memory per coroutine.
54 - manage PL_top_env differently, hopefully to avoid panic: top_env.
55 - timeout argument was not properly used in Coro::Socket.
56 - allow limited forms of subclassing in Coro::Handle/Coro::Socket.
57 - emulate undocumented(!) functionality of IO::Socket required
58 by LWP(!!).
59 - updated eg/lwp to work with newer lwp's.
60 - remove "FATAL: uncaught exception" prefix. Coroutines that die
61 kill the whole process, just as exceptions in the main "coroutine"
62 did already.
63
642.1 Wed Nov 1 23:01:13 CET 2006
65 - fix a long-standing bug in Coro::Select where select with
66 zero timeout would instead change the current default filehandle.
67 - use a simpler and hopefully more robust way to clone padlists
68 (uses less memory and a perl function instead of our own).
69 - coro can now create a stack guard area on many architectures.
70 - Coro::AIO properly reexports additional functions from IO::AIO.
71 - updated libcoro with a workaround for OS X,
72 pach and testing by Michael Schwern.
73
742.0 Tue Oct 24 05:47:17 CEST 2006
75 - support additional aio requests in Coro::AIO.
76
771.9 (never properly released due to a glitch)
78
791.8 Thu Feb 2 00:59:06 CET 2006
80 - applied suggested patch by SAMV to avoid problems during stupid
81 mark & sweep gc run.
82 - applied patch by Scott Walters for 5.9.3 compatibility.
83
841.7 Tue Dec 27 01:41:58 CET 2005
85 - added Coro::AIO, a thin wrapper around IO::AIO.
86 - improved Makefile.PL explanations.
87
881.6 Mon Dec 12 21:30:05 CET 2005
89 - additionally save PM_curpm might fix as-of-yet
90 unseen problems with regex matches being attributed to the
91 wrong package.
92 - add t/10_bugs.t, which currently checks against imho broken
93 perls that use 0.26MB of stack space per Perl_magic_get
94 invocation (newer linuxes) as opposed to the 0.0002MB perl
95 normally uses.
96 - make stacksize configurable for the ultimate debian experience.
97
981.51 Mon Dec 12 18:48:36 CET 2005
99 - remove debugging warn() accidentally left in Coro::Select.
100
1011.5 Tue Nov 29 13:32:44 CET 2005
102 - use Coro::Event inside Coro::Select to avoid spurious deadlocks.
103 - fix Coro::Select 'select'.
104 - strict'ify some modules.
105 - libcoro errornously restored the SIGUSR2 handler to SIGUSR1.
106 - use XSLoader in selected modules.
107 - remove some 5.6 compatibility cruft.
108
1091.4 Tue Sep 6 00:11:05 CEST 2005
110 - libcoro did not take into account the trampoline on amd64,
111 when 'l'inux method was used.
112
1131.31 Tue Aug 30 23:31:33 CEST 2005
114 - some portability fixes/workarounds.
115
1161.3 Sat Aug 20 03:08:56 CEST 2005
117 - no code changes. module seems to work fine.
118 - improve Coro::State docs, remove reference to nonexisting
119 Coro::State::flush method.
120 - no longer autodetect windows, present it as an option instead.
121
1221.2 Mon May 16 02:00:55 CEST 2005
3 - included libcoro.c earlier in State.xs, might improve portability. 123 - included libcoro.c earlier in State.xs, might improve portability.
124 - use a faster and possibly more stable Coro::Cont implementation.
125 - accept x86_64 in addition to amd64 for optimized linux-amd64 support.
126 - fix bugs Coro::SemaphoreSet that could cause locks never to be freed.
127 - fix bugs in CoroAPI.h and document it in Coro::MakeMaker.
