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: destroy gets only called on cancel: fix(?) 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)).
7
84.13
9 - add Coro::Storable::blocking_thaw.
10 - use a vastly more complicated technique to localise
11 $SIG{__WARN/DIE__} that also works on perls <= 5.8.8.
12
134.11 Thu Oct 11 02:40:24 CEST 2007
14 - port to threaded perls.
15
164.1 Thu Oct 11 02:38:16 CEST 2007
17 - incompatible change: $SIG{__DIE__} and $SIG{__WARN__} will now
18 be local to each coro (see Coro::State).
19 - incompatible change: for very deep reasons, cede and cede_notself
20 cannot return anything, so nothing will be returned.
21 - possibly bring back 5.10 compatibility (untested).
22 - work around stupid (and wrong) warning on 5.10 :(.
23 - overlay the saved state over the context stack. This saves
24 a few hundred bytes per coroutine on average and also
25 speeds up context switching a bit.
26 - further tune default stack sizes.
27 - (more) correctly calculate stack usage in coro_rss.
28 - Coro::Storable::blocking_* did not properly lock
29 resulting in races between coroutines.
30 - added Coro::Storable::guard.
31 - stopping to trace a coroutine could destroy the cctx of
32 an unrelated coroutine.
33 - explain the relationship between Perl and C coroutines in
34 more detail in Coro::State.
35 - Coro::Util::inet_aton did not short-circuit dotted quad forms,
36 causing a fork per resolve. This also affected Coro::Socket.
37 - switch to a separate stack in $coro->call/eval to avoid
38 invalidating pointers.
39
404.03 Sat Oct 6 21:24:00 CEST 2007
41 - added Coro::throw method.
42 - minor code cleanups.
43
444.02 Sat Oct 6 02:36:47 CEST 2007
45 - fix a very minor per-coroutine memleak (a single codereference).
46 - fixed a bug where the currently in-use c context would be freed
47 prematurely (can happen only when programs change the stacksize
48 or use tracing).
49 - tracing can no longer keep a coro alive after it terminated.
50 - do static branch prediction in the common path for gcc. gives
51 about 2-5% speed improvement here.
52
534.01 Fri Oct 5 22:10:49 CEST 2007
54 - instead of recreating *a* standard output handle we simply
55 use STDOUT, which is faster and hopefully more robust.
56
574.0 Fri Oct 5 12:56:00 CEST 2007
58 - incompatibly changed Coro::Storable::freeze.
59 - major new feature: added Coro::Debug, for interactive coroutine
60 debugging, tracing and much more.
61 - major bug fix: unbelievable, but true: $_, $/ and many other
62 "saved" variables actually weren't being saved. This has been fixed,
63 of course, while increasing performance while losing all the save
64 flags.
65 - save flags are gone, and all the api functions dealing with them.
66 - added Coro::Semaphore::adjust.
67 - added Coro::Util::fork_eval.
68 - added Coro::Storable::{nfreeze,blocking_{freeze,nfreeze}}.
69 - added Coro::killall.
70 - reduce initial stack sizes to allow for "micro-coroutines".
71 - better async_pool resource management, moved parts of async_pool
72 handling to XS (major speed improvement).
73 - actually croak before modifying important data structures.
74 - refuse to transfer while compiling.
75 - possibly support eval EXPR better now.
76 - enable assembly per default on linux+bsd x86+amd64.
77 - all internal members were renamed _something for easier subclassing.
78 - many minor tweaks.
79
803.63 Wed May 16 14:10:06 CEST 2007
81 - implement handcoded assembly for x86/amd64 SVR ABI.
82
833.62 Fri Apr 27 21:36:06 CEST 2007
84 - upgrade libcoro (which might set unwind info correctly).
85 - change default on linux to setjmp/longjmp.
86
873.61 Thu Apr 19 12:36:18 CEST 2007
88 - Coro::Storable caused an endless loop when thawing invalid
89 pst's sometimes.
90 - use a Semaphore in Coro::Storable, as Storable doesn't
91 seem to be reentrant (although it is documented to
92 be threadsafe...).
93 - fix Coro::Signal to bring back the original unreliable
94 but stateful semantics.
95 - fixed a lot of typos in Coro.pm (patch submitted by David
96 Steinbrunner, which applied flawlessly).
97
983.6 Sat Apr 14 17:13:31 CEST 2007
99 - added some bugfixes to get eg/myhttpd working again.
100 - added Coro::Storable for often-cede'ing freeze/thaw.
101 - try to do a clean exit when a coroutine calls exit
102 (EXPERIMENTAL).
103 - got rid of indirect call through _coro_init.
104 - updated the partly antique examples in eg/ to
105 work again and be a bit less magic, too.
106 - fixed Coro::Signal semantics to work as documented again.
107
1083.55 Sun Mar 25 01:20:47 CET 2007
109 - add SAVE_DEFFH to save the default filehandle and enable
110 it by default.
111 - finally move socket-operations from Coro::Socket to Coro::Handle
112 to be able to unblock foreign sockets.
113 - add Coro::State::save_also and guarded_save.
114 - add count accessor to Coro::Semaphore.
115 - add Coro::State::cctx_stacksize.
116 - just for the fun of it, do not rely on implicit context,
117 which can dramatically improve performance, but people
118 using windows-process-emulation perls do not care much about
119 performance.
120
1213.51 Sun Mar 4 14:18:04 CET 2007
122 - fixed a problem when you weakened references to Coro::State's
123 (patch by Yuval Kogman).
124
1253.501 Wed Feb 28 12:44:07 CET 2007
126 - rename some global symbols as macosx from hell redefines
127 them without asking.
128
1293.5 Tue Feb 13 20:22:53 CET 2007
130 - do AnyEvent model detection earlier, avoiding problems
131 caused by first using AnyEvent and later Coro::Event.
132 - implement and document Coro::Event event objects.
133 - fix a potential problem in Coro::Event causing crashes.
134 - initialise PL_comppad when creating a new coroutine,
135 avoids crashes on early coro destruction.
136
1373.41 Mon Jan 22 19:19:49 CET 2007
138 - readline on Coro::Handle did not support undefined $/,
139 nor did it deliver partial lines on EOF or error.
140 - implement malloc fallback for stack allocation because
141 stupid broken idiotic OSX has a stupid broken
142 idiotic fits-the-whole-os mmap "implementation" and
143 my dick feels longer if Coro is portable even to
144 obsolete platforms.
145
1463.4 Fri Jan 19 21:52:54 CET 2007
147 - remove t/09_timer.t, as it isn't really testing much
148 but was rather flaky in practise.
149 - async_pool coro would keep arguments and callback alive until
150 it was reused.
151 - cancellation of a coroutine could cause spurious idle calls
152 in cede_notself.
5 153
63.3 Sat Jan 6 03:45:00 CET 2007 1543.3 Sat Jan 6 03:45:00 CET 2007
7 - implement $coro->on_destroy. 155 - implement $coro->on_destroy.
8 - Coro::Event blocking semantics have been changed, 156 - Coro::Event blocking semantics have been changed,
9 documented and - hopefully - improved. 157 documented and - hopefully - improved.
