2 2
33.0 3TODO: better (earlier) error messages on broken transfer's
4TODO: destroy gets only called on cancel: fix(?)
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).
9
10 - implement handcoded assembly for x86/amd64 SVR ABI.
11
123.62 Fri Apr 27 21:36:06 CEST 2007
13 - upgrade libcoro (which might set unwind info correctly).
14 - change default on linux to setjmp/longjmp.
15
163.61 Thu Apr 19 12:36:18 CEST 2007
17 - Coro::Storable caused an endless loop when thawing invalid
18 pst's sometimes.
19 - use a Semaphore in Coro::Storable, as Storable doesn't
20 seem to be reentrant (although it is documented to
21 be threadsafe...).
22 - fix Coro::Signal to bring back the original unreliable
23 but stateful semantics.
24 - fixed a lot of typos in Coro.pm (patch submitted by David
25 Steinbrunner, which applied flawlessly).
26
273.6 Sat Apr 14 17:13:31 CEST 2007
28 - added some bugfixes to get eg/myhttpd working again.
29 - added Coro::Storable for often-cede'ing freeze/thaw.
30 - try to do a clean exit when a coroutine calls exit
31 (EXPERIMENTAL).
32 - got rid of indirect call through _coro_init.
33 - updated the partly antique examples in eg/ to
34 work again and be a bit less magic, too.
35 - fixed Coro::Signal semantics to work as documented again.
36
373.55 Sun Mar 25 01:20:47 CET 2007
38 - add SAVE_DEFFH to save the default filehandle and enable
39 it by default.
40 - finally move socket-operations from Coro::Socket to Coro::Handle
41 to be able to unblock foreign sockets.
42 - add Coro::State::save_also and guarded_save.
43 - add count accessor to Coro::Semaphore.
44 - add Coro::State::cctx_stacksize.
45 - just for the fun of it, do not rely on implicit context,
46 which can dramatically improve performance, but people
47 using windows-process-emulation perls do not care much about
48 performance.
49
503.51 Sun Mar 4 14:18:04 CET 2007
51 - fixed a problem when you weakened references to Coro::State's
52 (patch by Yuval Kogman).
53
543.501 Wed Feb 28 12:44:07 CET 2007
55 - rename some global symbols as macosx from hell redefines
56 them without asking.
57
583.5 Tue Feb 13 20:22:53 CET 2007
59 - do AnyEvent model detection earlier, avoiding problems
60 caused by first using AnyEvent and later Coro::Event.
61 - implement and document Coro::Event event objects.
62 - fix a potential problem in Coro::Event causing crashes.
63 - initialise PL_comppad when creating a new coroutine,
64 avoids crashes on early coro destruction.
65
663.41 Mon Jan 22 19:19:49 CET 2007
67 - readline on Coro::Handle did not support undefined $/,
68 nor did it deliver partial lines on EOF or error.
69 - implement malloc fallback for stack allocation because
70 stupid broken idiotic OSX has a stupid broken
71 idiotic fits-the-whole-os mmap "implementation" and
72 my dick feels longer if Coro is portable even to
73 obsolete platforms.
74
753.4 Fri Jan 19 21:52:54 CET 2007
76 - remove t/09_timer.t, as it isn't really testing much
77 but was rather flaky in practise.
78 - async_pool coro would keep arguments and callback alive until
79 it was reused.
80 - cancellation of a coroutine could cause spurious idle calls
81 in cede_notself.
82
833.3 Sat Jan 6 03:45:00 CET 2007
84 - implement $coro->on_destroy.
85 - Coro::Event blocking semantics have been changed,
86 documented and - hopefully - improved.
87 - fix nice adding, not subtracting, from priority.
88 - fix ->prio and api_is_ready (patch by Mark Hinds).
89 - fixed an assert ("... == prev__cctx->idle_te")
90 that could errronously trigger.
91 - fix various large and small memleaks.
92 - use a (hopefully) more stable cancel implementation
93 that immediately frees the coroutine data.
94 - cede/cede_notself return a status now.
95 - added Coro::guard function.
96 - added a global coroutine pool for jobs (on my machine,
97 I can create and execute 48k simple coros/s with async,
98 and 128k coros with async_pool).
99 - Coro::AIO now uses the coroutine priority as io priority.
100
1013.2 Fri Dec 22 05:07:09 CET 2006
102 - improve portability to slightly older perls.
103 - use cleaner coroutine destruction.
104 - simplify configuration for users.
105 - optionally (unrecommended) prefer perl functions over
106 their coro replacements.
107
1083.11 Tue Dec 5 13:11:24 CET 2006
109 - fixed some bogus assert's, but as perl.h disables assert even
110 without NDEBUG (thank you very much), not too many people should
111 notice (that did include myself). Andreas König noticed, though :)
112 - do not save/restore PL_sortcxix on >= 5.9.x, it doesn't seem to have
113 it. Also noticed by Andreas König :)
114 - save/restore tainted status.
115 - verified to pass the testsuite on my 5.9.5.
116
1173.1 Mon Dec 4 23:03:40 CET 2006
118 - INCOMPATIBLE CHANGE: $/ is now per-coroutine (but slow).
119 - incompatible change: transfer flags are now per-state.
120 - give a better error message on deadlock.
121 - document Coro::nready.
122 - enhanced testsuite.
123
1243.01 Sun Dec 3 23:47:42 CET 2006
125 - forgot to include Coro::Timer.
