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

53.3 84.1
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 - further tune default stack sizes.
17 - (more) correctly calculate stack usage in coro_rss.
18 - Coro::Storable::blocking_* did not properly lock
19 resulting in races between coroutines.
20 - added Coro::Storable::guard.
21
224.03 Sat Oct 6 21:24:00 CEST 2007
23 - added Coro::throw method.
24 - minor code cleanups.
25
264.02 Sat Oct 6 02:36:47 CEST 2007
27 - fix a very minor per-coroutine memleak (a single codereference).
28 - fixed a bug where the currently in-use c context would be freed
29 prematurely (can happen only when programs change the stacksize
30 or use tracing).
31 - tracing can no longer keep a coro alive after it terminated.
32 - do static branch prediction in the common path for gcc. gives
33 about 2-5% speed improvement here.
34
354.01 Fri Oct 5 22:10:49 CEST 2007
36 - instead of recreating *a* standard output handle we simply
37 use STDOUT, which is faster and hopefully more robust.
38
394.0 Fri Oct 5 12:56:00 CEST 2007
40 - incompatibly changed Coro::Storable::freeze.
41 - major new feature: added Coro::Debug, for interactive coroutine
42 debugging, tracing and much more.
43 - major bug fix: unbelievable, but true: $_, $/ and many other
44 "saved" variables actually weren't being saved. This has been fixed,
45 of course, while increasing performance while losing all the save
46 flags.
47 - save flags are gone, and all the api functions dealing with them.
48 - added Coro::Semaphore::adjust.
49 - added Coro::Util::fork_eval.
50 - added Coro::Storable::{nfreeze,blocking_{freeze,nfreeze}}.
51 - added Coro::killall.
52 - reduce initial stack sizes to allow for "micro-coroutines".
53 - better async_pool resource management, moved parts of async_pool
54 handling to XS (major speed improvement).
55 - actually croak before modifying important data structures.
56 - refuse to transfer while compiling.
57 - possibly support eval EXPR better now.
58 - enable assembly per default on linux+bsd x86+amd64.
59 - all internal members were renamed _something for easier subclassing.
60 - many minor tweaks.
61
623.63 Wed May 16 14:10:06 CEST 2007
63 - implement handcoded assembly for x86/amd64 SVR ABI.
64
653.62 Fri Apr 27 21:36:06 CEST 2007
66 - upgrade libcoro (which might set unwind info correctly).
67 - change default on linux to setjmp/longjmp.
68
693.61 Thu Apr 19 12:36:18 CEST 2007
70 - Coro::Storable caused an endless loop when thawing invalid
71 pst's sometimes.
72 - use a Semaphore in Coro::Storable, as Storable doesn't
73 seem to be reentrant (although it is documented to
74 be threadsafe...).
75 - fix Coro::Signal to bring back the original unreliable
76 but stateful semantics.
77 - fixed a lot of typos in Coro.pm (patch submitted by David
78 Steinbrunner, which applied flawlessly).
79
803.6 Sat Apr 14 17:13:31 CEST 2007
81 - added some bugfixes to get eg/myhttpd working again.
82 - added Coro::Storable for often-cede'ing freeze/thaw.
83 - try to do a clean exit when a coroutine calls exit
84 (EXPERIMENTAL).
85 - got rid of indirect call through _coro_init.
86 - updated the partly antique examples in eg/ to
87 work again and be a bit less magic, too.
88 - fixed Coro::Signal semantics to work as documented again.
89
903.55 Sun Mar 25 01:20:47 CET 2007
91 - add SAVE_DEFFH to save the default filehandle and enable
92 it by default.
93 - finally move socket-operations from Coro::Socket to Coro::Handle
94 to be able to unblock foreign sockets.
95 - add Coro::State::save_also and guarded_save.
96 - add count accessor to Coro::Semaphore.
97 - add Coro::State::cctx_stacksize.
98 - just for the fun of it, do not rely on implicit context,
99 which can dramatically improve performance, but people
100 using windows-process-emulation perls do not care much about
101 performance.
102
1033.51 Sun Mar 4 14:18:04 CET 2007
104 - fixed a problem when you weakened references to Coro::State's
105 (patch by Yuval Kogman).
106
1073.501 Wed Feb 28 12:44:07 CET 2007
108 - rename some global symbols as macosx from hell redefines
109 them without asking.
110
1113.5 Tue Feb 13 20:22:53 CET 2007
112 - do AnyEvent model detection earlier, avoiding problems
113 caused by first using AnyEvent and later Coro::Event.
114 - implement and document Coro::Event event objects.
115 - fix a potential problem in Coro::Event causing crashes.
116 - initialise PL_comppad when creating a new coroutine,
117 avoids crashes on early coro destruction.
118
1193.41 Mon Jan 22 19:19:49 CET 2007
120 - readline on Coro::Handle did not support undefined $/,
121 nor did it deliver partial lines on EOF or error.
122 - implement malloc fallback for stack allocation because
123 stupid broken idiotic OSX has a stupid broken
124 idiotic fits-the-whole-os mmap "implementation" and
125 my dick feels longer if Coro is portable even to
126 obsolete platforms.
127
1283.4 Fri Jan 19 21:52:54 CET 2007
129 - remove t/09_timer.t, as it isn't really testing much
130 but was rather flaky in practise.
131 - async_pool coro would keep arguments and callback alive until
132 it was reused.
133 - cancellation of a coroutine could cause spurious idle calls
134 in cede_notself.
135
1363.3 Sat Jan 6 03:45:00 CET 2007
6 - implement $coro->on_destroy. 137 - implement $coro->on_destroy.
7 - Coro::Event blocking semantics have been changed, 138 - Coro::Event blocking semantics have been changed,
8 documented and - hopefully - improved. 139 documented and - hopefully - improved.
9 - fix nice adding, not subtracting, from priority. 140 - fix nice adding, not subtracting, from priority.
10 - fix ->prio and api_is_ready (patch by Mark Hinds). 141 - fix ->prio and api_is_ready (patch by Mark Hinds).
11 - fixed an assert ("... == prev__cctx->idle_te") 142 - fixed an assert ("... == prev__cctx->idle_te")
12 that could errronously trigger. 143 that could errronously trigger.
144 - fix various large and small memleaks.
145 - use a (hopefully) more stable cancel implementation
146 that immediately frees the coroutine data.
147 - cede/cede_notself return a status now.
148 - added Coro::guard function.
149 - added a global coroutine pool for jobs (on my machine,
150 I can create and execute 48k simple coros/s with async,
151 and 128k coros with async_pool).
152 - Coro::AIO now uses the coroutine priority as io priority.
13 153
143.2 Fri Dec 22 05:07:09 CET 2006 1543.2 Fri Dec 22 05:07:09 CET 2006
15 - improve portability to slightly older perls. 155 - improve portability to slightly older perls.
16 - use cleaner coroutine destruction. 156 - use cleaner coroutine destruction.
17 - simplify configuration for users. 157 - simplify configuration for users.
