1Revision history for Perl extension Coro. 1Revision history for Perl extension Coro.
2 2
3TODO: better (earlier) error messages on broken transfer's 3TODO: localise SIG{__DIE__} and/or __WARN__
4TODO: "internals mode" 4TODO: should explore PerlIO::via::CoroCede and PerlIO::via::CoroAIO.
5TODO: maybe implement a default message channel, very much like Erlang
6 (which is cool in a lot of important aspects (failures!),
7 but very lacking in others (higher level ipc)).

94.03 Sat Oct 6 21:24:00 CEST 2007
10 - added Coro::throw method.
11 - minor code cleanups.
12
134.02 Sat Oct 6 02:36:47 CEST 2007
14 - fix a very minor per-coroutine memleak (a single codereference).
15 - fixed a bug where the currently in-use c context would be freed
16 prematurely (can happen only when programs change the stacksize
17 or use tracing).
18 - tracing can no longer keep a coro alive after it terminated.
19 - do static branch prediction in the common path for gcc. gives
20 about 2-5% speed improvement here.
21
224.01 Fri Oct 5 22:10:49 CEST 2007
23 - instead of recreating *a* standard output handle we simply
24 use STDOUT, which is faster and hopefully more robust.
25
264.0 Fri Oct 5 12:56:00 CEST 2007
27 - incompatibly changed Coro::Storable::freeze.
28 - major new feature: added Coro::Debug, for interactive coroutine
29 debugging, tracing and much more.
30 - major bug fix: unbelievable, but true: $_, $/ and many other
31 "saved" variables actually weren't being saved. This has been fixed,
32 of course, while increasing performance while losing all the save
33 flags.
34 - save flags are gone, and all the api functions dealing with them.
35 - added Coro::Semaphore::adjust.
36 - added Coro::Util::fork_eval.
37 - added Coro::Storable::{nfreeze,blocking_{freeze,nfreeze}}.
38 - added Coro::killall.
39 - reduce initial stack sizes to allow for "micro-coroutines".
40 - better async_pool resource management, moved parts of async_pool
41 handling to XS (major speed improvement).
42 - actually croak before modifying important data structures.
43 - refuse to transfer while compiling.
44 - possibly support eval EXPR better now.
45 - enable assembly per default on linux+bsd x86+amd64.
46 - all internal members were renamed _something for easier subclassing.
47 - many minor tweaks.
48
493.63 Wed May 16 14:10:06 CEST 2007
50 - implement handcoded assembly for x86/amd64 SVR ABI.
51
523.62 Fri Apr 27 21:36:06 CEST 2007
53 - upgrade libcoro (which might set unwind info correctly).
54 - change default on linux to setjmp/longjmp.
55
563.61 Thu Apr 19 12:36:18 CEST 2007
57 - Coro::Storable caused an endless loop when thawing invalid
58 pst's sometimes.
59 - use a Semaphore in Coro::Storable, as Storable doesn't
60 seem to be reentrant (although it is documented to
61 be threadsafe...).
62 - fix Coro::Signal to bring back the original unreliable
63 but stateful semantics.
64 - fixed a lot of typos in Coro.pm (patch submitted by David
65 Steinbrunner, which applied flawlessly).
66
673.6 Sat Apr 14 17:13:31 CEST 2007
68 - added some bugfixes to get eg/myhttpd working again.
69 - added Coro::Storable for often-cede'ing freeze/thaw.
70 - try to do a clean exit when a coroutine calls exit
71 (EXPERIMENTAL).
72 - got rid of indirect call through _coro_init.
73 - updated the partly antique examples in eg/ to
74 work again and be a bit less magic, too.
75 - fixed Coro::Signal semantics to work as documented again.
76
773.55 Sun Mar 25 01:20:47 CET 2007
78 - add SAVE_DEFFH to save the default filehandle and enable
79 it by default.
80 - finally move socket-operations from Coro::Socket to Coro::Handle
81 to be able to unblock foreign sockets.
82 - add Coro::State::save_also and guarded_save.
83 - add count accessor to Coro::Semaphore.
84 - add Coro::State::cctx_stacksize.
85 - just for the fun of it, do not rely on implicit context,
86 which can dramatically improve performance, but people
87 using windows-process-emulation perls do not care much about
88 performance.
89
903.51 Sun Mar 4 14:18:04 CET 2007
91 - fixed a problem when you weakened references to Coro::State's
92 (patch by Yuval Kogman).
93
943.501 Wed Feb 28 12:44:07 CET 2007
95 - rename some global symbols as macosx from hell redefines
96 them without asking.
97
983.5 Tue Feb 13 20:22:53 CET 2007
99 - do AnyEvent model detection earlier, avoiding problems
100 caused by first using AnyEvent and later Coro::Event.
101 - implement and document Coro::Event event objects.
102 - fix a potential problem in Coro::Event causing crashes.
103 - initialise PL_comppad when creating a new coroutine,
104 avoids crashes on early coro destruction.
105
1063.41 Mon Jan 22 19:19:49 CET 2007
107 - readline on Coro::Handle did not support undefined $/,
108 nor did it deliver partial lines on EOF or error.
109 - implement malloc fallback for stack allocation because
110 stupid broken idiotic OSX has a stupid broken
111 idiotic fits-the-whole-os mmap "implementation" and
112 my dick feels longer if Coro is portable even to
113 obsolete platforms.
114
1153.4 Fri Jan 19 21:52:54 CET 2007
116 - remove t/09_timer.t, as it isn't really testing much
117 but was rather flaky in practise.
118 - async_pool coro would keep arguments and callback alive until
119 it was reused.
120 - cancellation of a coroutine could cause spurious idle calls
121 in cede_notself.
122
1233.3 Sat Jan 6 03:45:00 CET 2007
124 - implement $coro->on_destroy.
125 - Coro::Event blocking semantics have been changed,
126 documented and - hopefully - improved.
127 - fix nice adding, not subtracting, from priority.
128 - fix ->prio and api_is_ready (patch by Mark Hinds).
129 - fixed an assert ("... == prev__cctx->idle_te")
130 that could errronously trigger.
131 - fix various large and small memleaks.
132 - use a (hopefully) more stable cancel implementation
133 that immediately frees the coroutine data.
134 - cede/cede_notself return a status now.
135 - added Coro::guard function.
136 - added a global coroutine pool for jobs (on my machine,
137 I can create and execute 48k simple coros/s with async,
138 and 128k coros with async_pool).
139 - Coro::AIO now uses the coroutine priority as io priority.
140
1413.2 Fri Dec 22 05:07:09 CET 2006
6 - improve portability to slightly older perls. 142 - improve portability to slightly older perls.
7 - use cleaner coroutine destruction. 143 - use cleaner coroutine destruction.
144 - simplify configuration for users.
145 - optionally (unrecommended) prefer perl functions over
146 their coro replacements.
