2 2
3TODO: check wether stack-sharing is still effective 3TODO: better (earlier) error messages on broken transfer's
4TODO: more effective stack sharing by having one "default stack" for "simple" coroutines? 4TODO: destroy gets only called on cancel: fix(?)
5TODO: verify exception frame changes and force stack copies? 5TODO: should explore PerlIO::via::CoroCede and PerlIO::via::CoroAIO.

7TODO: eg/event
8 - added some bugfixes to get eg/myhttpd working again.
9 - added Coro::Storable for often-cede'ing freeze/thaw.
10 - try to do a clean exit when a coroutine calls exit
11 (EXPERIMENTAL).
12 - got rid of indirect call through _coro_init.
13 - updated the partly antique examples in eg/ to
14 work again and be a bit less magic, too.
15 - fixed Coro::Signal semantics to work as documented again.
16
173.55 Sun Mar 25 01:20:47 CET 2007
18 - add SAVE_DEFFH to save the default filehandle and enable
19 it by default.
20 - finally move socket-operations from Coro::Socket to Coro::Handle
21 to be able to unblock foreign sockets.
22 - add Coro::State::save_also and guarded_save.
23 - add count accessor to Coro::Semaphore.
24 - add Coro::State::cctx_stacksize.
25 - just for the fun of it, do not rely on implicit context,
26 which can dramatically improve performance, but people
27 using windows-process-emulation perls do not care much about
28 performance.
29
303.51 Sun Mar 4 14:18:04 CET 2007
31 - fixed a problem when you weakened references to Coro::State's
32 (patch by Yuval Kogman).
33
343.501 Wed Feb 28 12:44:07 CET 2007
35 - rename some global symbols as macosx from hell redefines
36 them without asking.
37
383.5 Tue Feb 13 20:22:53 CET 2007
39 - do AnyEvent model detection earlier, avoiding problems
40 caused by first using AnyEvent and later Coro::Event.
41 - implement and document Coro::Event event objects.
42 - fix a potential problem in Coro::Event causing crashes.
43 - initialise PL_comppad when creating a new coroutine,
44 avoids crashes on early coro destruction.
45
463.41 Mon Jan 22 19:19:49 CET 2007
47 - readline on Coro::Handle did not support undefined $/,
48 nor did it deliver partial lines on EOF or error.
49 - implement malloc fallback for stack allocation because
50 stupid broken idiotic OSX has a stupid broken
51 idiotic fits-the-whole-os mmap "implementation" and
52 my dick feels longer if Coro is portable even to
53 obsolete platforms.
54
553.4 Fri Jan 19 21:52:54 CET 2007
56 - remove t/09_timer.t, as it isn't really testing much
57 but was rather flaky in practise.
58 - async_pool coro would keep arguments and callback alive until
59 it was reused.
60 - cancellation of a coroutine could cause spurious idle calls
61 in cede_notself.
62
633.3 Sat Jan 6 03:45:00 CET 2007
64 - implement $coro->on_destroy.
65 - Coro::Event blocking semantics have been changed,
66 documented and - hopefully - improved.
67 - fix nice adding, not subtracting, from priority.
68 - fix ->prio and api_is_ready (patch by Mark Hinds).
69 - fixed an assert ("... == prev__cctx->idle_te")
70 that could errronously trigger.
71 - fix various large and small memleaks.
72 - use a (hopefully) more stable cancel implementation
73 that immediately frees the coroutine data.
74 - cede/cede_notself return a status now.
75 - added Coro::guard function.
76 - added a global coroutine pool for jobs (on my machine,
77 I can create and execute 48k simple coros/s with async,
78 and 128k coros with async_pool).
79 - Coro::AIO now uses the coroutine priority as io priority.
80
813.2 Fri Dec 22 05:07:09 CET 2006
82 - improve portability to slightly older perls.
83 - use cleaner coroutine destruction.
84 - simplify configuration for users.
85 - optionally (unrecommended) prefer perl functions over
86 their coro replacements.
87
883.11 Tue Dec 5 13:11:24 CET 2006
89 - fixed some bogus assert's, but as perl.h disables assert even
90 without NDEBUG (thank you very much), not too many people should
91 notice (that did include myself). Andreas König noticed, though :)
92 - do not save/restore PL_sortcxix on >= 5.9.x, it doesn't seem to have
93 it. Also noticed by Andreas König :)
94 - save/restore tainted status.
95 - verified to pass the testsuite on my 5.9.5.
96
973.1 Mon Dec 4 23:03:40 CET 2006
98 - INCOMPATIBLE CHANGE: $/ is now per-coroutine (but slow).
99 - incompatible change: transfer flags are now per-state.
100 - give a better error message on deadlock.
101 - document Coro::nready.
102 - enhanced testsuite.
103
1043.01 Sun Dec 3 23:47:42 CET 2006
105 - forgot to include Coro::Timer.
106
1073.0 Sun Dec 3 22:57:25 CET 2006
108 - the "FINALLY COMPLETELY STABLE" release (coming soon:
109 the "FAMOUS LAST WORDS" release).
110 - implement a new stack sharing algorithm, which uses a stack
111 pool (size currently hardcoded).
112 - make stack sharing mandatory (it no longer uses a heuristic).
113 - eval/die no longer cause weird problems under heavy use.
7 - Coro::Event could cause livelocks if it was used but 114 - Coro::Event could cause livelocks if it was used but
8 Event watchers were used directly. 115 no Coro::Event watchers were used.
116 - Coro::Event now uses asynccheck as prepare does not
117 check for changed watchers.
118 - Coro::Event allows multiple waiting coros and will wake up one
119 per event.
9 - Coro::Event should be cleaner and more efficient now. 120 - Coro::Event should be cleaner and more efficient now.
121 - new utility function Coro::unblock_sub.
122 - document the sad fact that Event is no longer reentrant.
123 - putting a coroutine into the ready queue twice could under
124 some circumstances lead to stack corruption.
10 - minor incompatibility: subclassing is supported directly now 125 - minor incompatibility: subclassing Coro::State is supported
11 without going through a _coro_state member. 126 directly now without going through a _coro_state member.
12 - process swicthing is much faster now. 127 - state/coro switching is much faster now.
13 - very minor optimisations and code/documentation cleanup. 128 - very minor optimisations and code/documentation cleanup.
14 - avoid problems due to compiler inlining. 129 - avoid problems due to compiler inlining.
15 - possibly better support for threads.
16 - removed timers from Coro::Timer -> use AnyEvent instead. 130 - removed timers from Coro::Timer -> use AnyEvent instead.
17 - replaced Coro::idle coroutine by (cleaner) idle handler. 131 - replaced Coro::idle coroutine by (cleaner) idle handler.
132 - updated to newest libcoro.
133 - implement enhanced support for valgrind.
134 - implement is_ready and return value for ready.
135 - removed Coro::Cont, it was a misnomer (it's generators),
136 and it was somewhat annoying to get it right. Will come back
137 if somebody asks for it :)
138 - many ->wait methods and Coro::Event could return
139 spuriously without the event having happened.

192.5 Tue Nov 7 12:22:33 CET 2006 1412.5 Tue Nov 7 12:22:33 CET 2006
20 - made Coro::Util, Coro::Select, Coro::Handle and Coro::Socket 142 - made Coro::Util, Coro::Select, Coro::Handle and Coro::Socket
21 use AnyEvent, moved them to Coro/. 143 use AnyEvent, moved them to Coro/.
22 - added Coro::LWP which contains all the uglyness required to 144 - added Coro::LWP which contains all the uglyness required to
