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: destroy gets only called on cancel: fix(?) 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)).
5 8
63.3 9 - incompatible change: $SIG{__DIE__} and $SIG{__WARN__} will now
10 be local to each coro (see Coro::State).
11 - possibly bring back 5.10 compatibility (untested).
12 - work around stupid (and wrong) warning on 5.10 :(.
13 - overlay the saved state over the context stack. This saves
14 a few hundred bytes per coroutine on average and also
15 speeds up context switching a bit.
16 - (more) correctly calculate stack usage in coro_rss.
17
184.03 Sat Oct 6 21:24:00 CEST 2007
19 - added Coro::throw method.
20 - minor code cleanups.
21
224.02 Sat Oct 6 02:36:47 CEST 2007
23 - fix a very minor per-coroutine memleak (a single codereference).
24 - fixed a bug where the currently in-use c context would be freed
25 prematurely (can happen only when programs change the stacksize
26 or use tracing).
27 - tracing can no longer keep a coro alive after it terminated.
28 - do static branch prediction in the common path for gcc. gives
29 about 2-5% speed improvement here.
30
314.01 Fri Oct 5 22:10:49 CEST 2007
32 - instead of recreating *a* standard output handle we simply
33 use STDOUT, which is faster and hopefully more robust.
34
354.0 Fri Oct 5 12:56:00 CEST 2007
36 - incompatibly changed Coro::Storable::freeze.
37 - major new feature: added Coro::Debug, for interactive coroutine
38 debugging, tracing and much more.
39 - major bug fix: unbelievable, but true: $_, $/ and many other
40 "saved" variables actually weren't being saved. This has been fixed,
41 of course, while increasing performance while losing all the save
42 flags.
43 - save flags are gone, and all the api functions dealing with them.
44 - added Coro::Semaphore::adjust.
45 - added Coro::Util::fork_eval.
46 - added Coro::Storable::{nfreeze,blocking_{freeze,nfreeze}}.
47 - added Coro::killall.
48 - reduce initial stack sizes to allow for "micro-coroutines".
49 - better async_pool resource management, moved parts of async_pool
50 handling to XS (major speed improvement).
51 - actually croak before modifying important data structures.
52 - refuse to transfer while compiling.
53 - possibly support eval EXPR better now.
54 - enable assembly per default on linux+bsd x86+amd64.
55 - all internal members were renamed _something for easier subclassing.
56 - many minor tweaks.
57
583.63 Wed May 16 14:10:06 CEST 2007
59 - implement handcoded assembly for x86/amd64 SVR ABI.
60
613.62 Fri Apr 27 21:36:06 CEST 2007
62 - upgrade libcoro (which might set unwind info correctly).
63 - change default on linux to setjmp/longjmp.
64
653.61 Thu Apr 19 12:36:18 CEST 2007
66 - Coro::Storable caused an endless loop when thawing invalid
67 pst's sometimes.
68 - use a Semaphore in Coro::Storable, as Storable doesn't
69 seem to be reentrant (although it is documented to
70 be threadsafe...).
71 - fix Coro::Signal to bring back the original unreliable
72 but stateful semantics.
73 - fixed a lot of typos in Coro.pm (patch submitted by David
74 Steinbrunner, which applied flawlessly).
75
763.6 Sat Apr 14 17:13:31 CEST 2007
77 - added some bugfixes to get eg/myhttpd working again.
78 - added Coro::Storable for often-cede'ing freeze/thaw.
79 - try to do a clean exit when a coroutine calls exit
80 (EXPERIMENTAL).
81 - got rid of indirect call through _coro_init.
82 - updated the partly antique examples in eg/ to
83 work again and be a bit less magic, too.
84 - fixed Coro::Signal semantics to work as documented again.
85
863.55 Sun Mar 25 01:20:47 CET 2007
87 - add SAVE_DEFFH to save the default filehandle and enable
88 it by default.
89 - finally move socket-operations from Coro::Socket to Coro::Handle
90 to be able to unblock foreign sockets.
91 - add Coro::State::save_also and guarded_save.
92 - add count accessor to Coro::Semaphore.
93 - add Coro::State::cctx_stacksize.
94 - just for the fun of it, do not rely on implicit context,
95 which can dramatically improve performance, but people
96 using windows-process-emulation perls do not care much about
97 performance.
98
993.51 Sun Mar 4 14:18:04 CET 2007
100 - fixed a problem when you weakened references to Coro::State's
101 (patch by Yuval Kogman).
102
1033.501 Wed Feb 28 12:44:07 CET 2007
104 - rename some global symbols as macosx from hell redefines
105 them without asking.
106
1073.5 Tue Feb 13 20:22:53 CET 2007
108 - do AnyEvent model detection earlier, avoiding problems
109 caused by first using AnyEvent and later Coro::Event.
110 - implement and document Coro::Event event objects.
111 - fix a potential problem in Coro::Event causing crashes.
112 - initialise PL_comppad when creating a new coroutine,
113 avoids crashes on early coro destruction.
114
1153.41 Mon Jan 22 19:19:49 CET 2007
116 - readline on Coro::Handle did not support undefined $/,
117 nor did it deliver partial lines on EOF or error.
118 - implement malloc fallback for stack allocation because
119 stupid broken idiotic OSX has a stupid broken
120 idiotic fits-the-whole-os mmap "implementation" and
121 my dick feels longer if Coro is portable even to
122 obsolete platforms.
123
1243.4 Fri Jan 19 21:52:54 CET 2007
125 - remove t/09_timer.t, as it isn't really testing much
126 but was rather flaky in practise.
127 - async_pool coro would keep arguments and callback alive until
128 it was reused.
129 - cancellation of a coroutine could cause spurious idle calls
130 in cede_notself.
131
1323.3 Sat Jan 6 03:45:00 CET 2007
7 - implement $coro->on_destroy. 133 - implement $coro->on_destroy.

10 - fix nice adding, not subtracting, from priority. 136 - fix nice adding, not subtracting, from priority.

12 - fixed an assert ("... == prev__cctx->idle_te") 138 - fixed an assert ("... == prev__cctx->idle_te")
13 that could errronously trigger. 139 that could errronously trigger.
14 - fix various large and small memleaks. 140 - fix various large and small memleaks.
15 - use a (hopefully) more stable cancel implementation 141 - use a (hopefully) more stable cancel implementation
16 that immediately frees the coroutine data. 142 that immediately frees the coroutine data.
143 - cede/cede_notself return a status now.
17 - added Coro::guard function. 144 - added Coro::guard function.
18 - added a global coroutine pool for jobs (on my machine, 145 - added a global coroutine pool for jobs (on my machine,
19 I can create and execute 48k simple coros/s with async, 146 I can create and execute 48k simple coros/s with async,
20 and 128k coros with async_pool). 147 and 128k coros with async_pool).
148 - Coro::AIO now uses the coroutine priority as io priority.
