33.0
4 - the "FINALLY COMPLETELY STABLE" release (coming soon:
5 the "FAMOUS LAST WORDS" release).
6 - implement a new stack sharing algorithm, which uses a stack
7 pool (size currently hardcoded).
8 - make stack sharing mandatory (it no longer uses a heuristic).
9 - eval/die no longer cause weird problems under heavy use.
10 - Coro::Event could cause livelocks if it was used but
11 no Coro::Event watchers were used.
12 - Coro::Event should be cleaner and more efficient now.
13 - new utility function Coro::unblock_sub.
14 - document the sad fact that Event is no longer reentrant.
15 - putting a coroutine into the ready queue twice could under
16 some circumstances lead to stack corruption.
17 - minor incompatibility: subclassing Coro::State is supported
18 directly now without going through a _coro_state member.
19 - state/coro switching is much faster now.
20 - very minor optimisations and code/documentation cleanup.
21 - avoid problems due to compiler inlining.
22 - removed timers from Coro::Timer -> use AnyEvent instead.
23 - replaced Coro::idle coroutine by (cleaner) idle handler.
24 - updated to newest libcoro.
25 - implement enhanced support for valgrind.
26 - implement is_ready and return value for ready.
27 - many ->wait methods and Coro::Event could return
28 spuriously without the event having happened.
29
302.5 Tue Nov 7 12:22:33 CET 2006
31 - made Coro::Util, Coro::Select, Coro::Handle and Coro::Socket
32 use AnyEvent, moved them to Coro/.
33 - added Coro::LWP which contains all the uglyness required to
34 make LWP non-blocking.
35 - should work with perl 5.9.x now (Andreas König made me do it).
36 - fixed another bug in Coro::Select when the timeout was undef.
37 - reuse PL_start_env for all coros, saves some memory per coroutine.
38 - manage PL_top_env differently, hopefully to avoid panic: top_env.
39 - timeout argument was not properly used in Coro::Socket.
40 - allow limited forms of subclassing in Coro::Handle/Coro::Socket.
41 - emulate undocumented(!) functionality of IO::Socket required
42 by LWP(!!).
43 - updated eg/lwp to work with newer lwp's.
44 - remove "FATAL: uncaught exception" prefix. Coroutines that die
45 kill the whole process, just as exceptions in the main "coroutine"
46 did already.
47
482.1 Wed Nov 1 23:01:13 CET 2006
49 - fix a long-standing bug in Coro::Select where select with
50 zero timeout would instead change the current default filehandle.
51 - use a simpler and hopefully more robust way to clone padlists
52 (uses less memory and a perl function instead of our own).
53 - coro can now create a stack guard area on many architectures.
54 - Coro::AIO properly reexports additional functions from IO::AIO.
55 - updated libcoro with a workaround for OS X,
56 pach and testing by Michael Schwern.
57
582.0 Tue Oct 24 05:47:17 CEST 2006
59 - support additional aio requests in Coro::AIO.
60
611.9 (never properly released due to a glitch)
62
631.8 Thu Feb 2 00:59:06 CET 2006
64 - applied suggested patch by SAMV to avoid problems during stupid
65 mark & sweep gc run.
66 - applied patch by Scott Walters for 5.9.3 compatibility.
67
681.7 Tue Dec 27 01:41:58 CET 2005
69 - added Coro::AIO, a thin wrapper around IO::AIO.
70 - improved Makefile.PL explanations.
71
721.6 Mon Dec 12 21:30:05 CET 2005
73 - additionally save PM_curpm might fix as-of-yet
74 unseen problems with regex matches being attributed to the
75 wrong package.
76 - add t/10_bugs.t, which currently checks against imho broken
77 perls that use 0.26MB of stack space per Perl_magic_get
78 invocation (newer linuxes) as opposed to the 0.0002MB perl
79 normally uses.
80 - make stacksize configurable for the ultimate debian experience.
81
821.51 Mon Dec 12 18:48:36 CET 2005
83 - remove debugging warn() accidentally left in Coro::Select.
84
851.5 Tue Nov 29 13:32:44 CET 2005
86 - use Coro::Event inside Coro::Select to avoid spurious deadlocks.
87 - fix Coro::Select 'select'.
88 - strict'ify some modules.
89 - libcoro errornously restored the SIGUSR2 handler to SIGUSR1.
90 - use XSLoader in selected modules.
91 - remove some 5.6 compatibility cruft.
92
931.4 Tue Sep 6 00:11:05 CEST 2005
94 - libcoro did not take into account the trampoline on amd64,
95 when 'l'inux method was used.
96
971.31 Tue Aug 30 23:31:33 CEST 2005
98 - some portability fixes/workarounds.
99
1001.3 Sat Aug 20 03:08:56 CEST 2005
101 - no code changes. module seems to work fine.
102 - improve Coro::State docs, remove reference to nonexisting
103 Coro::State::flush method.
104 - no longer autodetect windows, present it as an option instead.
105
1061.2 Mon May 16 02:00:55 CEST 2005
107 - included libcoro.c earlier in State.xs, might improve portability.
108 - use a faster and possibly more stable Coro::Cont implementation.
109 - accept x86_64 in addition to amd64 for optimized linux-amd64 support.
110 - fix bugs Coro::SemaphoreSet that could cause locks never to be freed.
111 - fix bugs in CoroAPI.h and document it in Coro::MakeMaker.
112
1131.11 Thu Mar 3 18:00:52 CET 2005
114 - change of contact address.
115
1161.1 Tue Feb 22 20:51:16 CET 2005
117 - support [l]inux method on amd64.
118 - allow some context switches while compiling/eval'ing.
119
1201.0 Tue Aug 10 03:47:27 CEST 2004
121 - Event 0.89 fixes the bug again.
122 - fix the remaining(??) memleak. I didn't free the cache-AV for
123 padlists, so one AV per created anon-sub leaked.
124
1250.97 Fri May 14 15:23:32 CEST 2004
126 - remove stupid gcc extension that was an experiment only anyway.
127
1280.96 Thu May 13 18:09:29 CEST 2004
129 - tell people if they have yet another broken Event variant.
130 - made Coro to work _better_ with threads (it seems that, as long
131 as you use Coros in one thread only everything will work fine.
132 Looking at the perl source the problem might be missing locking
133 between Coro and some perl internal routines. That's not easily
134 fixable).
135 - (hopefully) got rid of the static xnext inside transfer.
136
1370.95 Sun Feb 15 03:20:28 CET 2004
138 - removed Coro::State::flush, implemented a new and much
139 faster caching mechanism by attaching magic to the CV.
140 - a memleak with (real) closures remains.
141 - dramatically reduced size of stacks to 65536 (linux/x86), after
142 observing that even myhttpd never had more than a kilobyte
143 of stack in use (stack is still only physically allocated in
144 pagesize increments for systems suporting mmap).
145 - fix for a "cygwin-64" architecture added, proposed by Stefan Traby.
146 - fix for threaded perl.
147
1480.9 Sun Nov 23 04:32:39 CET 2003
149 - fix a few very hard to track down but (of course) stupid
150 memory leaks.
151 - stringify version number to avoid locale problems :(.
152 - perl 5.9.0 does not have SvPADBUSY, reported by Scott Walters,
153 hopefully ignoring it "just works".
154
1550.8 Wed Nov 5 19:38:40 CET 2003
156 - port to perl5.005_03, but only 5.8.x+ is supported!
157 - honor LocalAddr even without LocalPort in Coro::Socket.

30.7 Tue May 27 03:12:38 CEST 2003 1590.7 Tue May 27 03:12:38 CEST 2003
4 - the version jump indicates some level of testing, not gobs 160 - the version jump indicates some level of testing, not gobs
5 of new features. 161 of new features.
6 - uh... I found the prompt function in ExtUtils::MakeMaker. 162 - uh... I found the prompt function in ExtUtils::MakeMaker.
