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)).
5 7
63.3 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 - stopping to trace a coroutine could destroy the cctx of
22 an unrelated coroutine.
23 - explain the relationship between Perl and C coroutines in
24 more detail in Coro::State.
25 - Coro::Util::inet_aton did not short-circuit dotted quad forms,
26 causing a fork per resolve. This also affected Coro::Socket.
27 - sped up Coro::Event next event handling by 15%, uses less memory.
28 - switch to a separate stack in $coro->call/eval to avoid
29 invalidating pointers.
30
314.03 Sat Oct 6 21:24:00 CEST 2007
32 - added Coro::throw method.
33 - minor code cleanups.
34
354.02 Sat Oct 6 02:36:47 CEST 2007
36 - fix a very minor per-coroutine memleak (a single codereference).
37 - fixed a bug where the currently in-use c context would be freed
38 prematurely (can happen only when programs change the stacksize
39 or use tracing).
40 - tracing can no longer keep a coro alive after it terminated.
41 - do static branch prediction in the common path for gcc. gives
42 about 2-5% speed improvement here.
43
444.01 Fri Oct 5 22:10:49 CEST 2007
45 - instead of recreating *a* standard output handle we simply
46 use STDOUT, which is faster and hopefully more robust.
47
484.0 Fri Oct 5 12:56:00 CEST 2007
49 - incompatibly changed Coro::Storable::freeze.
50 - major new feature: added Coro::Debug, for interactive coroutine
51 debugging, tracing and much more.
52 - major bug fix: unbelievable, but true: $_, $/ and many other
53 "saved" variables actually weren't being saved. This has been fixed,
54 of course, while increasing performance while losing all the save
55 flags.
56 - save flags are gone, and all the api functions dealing with them.
57 - added Coro::Semaphore::adjust.
58 - added Coro::Util::fork_eval.
59 - added Coro::Storable::{nfreeze,blocking_{freeze,nfreeze}}.
60 - added Coro::killall.
61 - reduce initial stack sizes to allow for "micro-coroutines".
62 - better async_pool resource management, moved parts of async_pool
63 handling to XS (major speed improvement).
64 - actually croak before modifying important data structures.
65 - refuse to transfer while compiling.
66 - possibly support eval EXPR better now.
67 - enable assembly per default on linux+bsd x86+amd64.
68 - all internal members were renamed _something for easier subclassing.
69 - many minor tweaks.
70
713.63 Wed May 16 14:10:06 CEST 2007
72 - implement handcoded assembly for x86/amd64 SVR ABI.
73
743.62 Fri Apr 27 21:36:06 CEST 2007
75 - upgrade libcoro (which might set unwind info correctly).
76 - change default on linux to setjmp/longjmp.
77
783.61 Thu Apr 19 12:36:18 CEST 2007
79 - Coro::Storable caused an endless loop when thawing invalid
80 pst's sometimes.
81 - use a Semaphore in Coro::Storable, as Storable doesn't
82 seem to be reentrant (although it is documented to
83 be threadsafe...).
84 - fix Coro::Signal to bring back the original unreliable
85 but stateful semantics.
86 - fixed a lot of typos in Coro.pm (patch submitted by David
87 Steinbrunner, which applied flawlessly).
88
893.6 Sat Apr 14 17:13:31 CEST 2007
90 - added some bugfixes to get eg/myhttpd working again.
91 - added Coro::Storable for often-cede'ing freeze/thaw.
92 - try to do a clean exit when a coroutine calls exit
93 (EXPERIMENTAL).
94 - got rid of indirect call through _coro_init.
95 - updated the partly antique examples in eg/ to
96 work again and be a bit less magic, too.
97 - fixed Coro::Signal semantics to work as documented again.
98
993.55 Sun Mar 25 01:20:47 CET 2007
100 - add SAVE_DEFFH to save the default filehandle and enable
101 it by default.
102 - finally move socket-operations from Coro::Socket to Coro::Handle
103 to be able to unblock foreign sockets.
104 - add Coro::State::save_also and guarded_save.
105 - add count accessor to Coro::Semaphore.
106 - add Coro::State::cctx_stacksize.
107 - just for the fun of it, do not rely on implicit context,
108 which can dramatically improve performance, but people
109 using windows-process-emulation perls do not care much about
110 performance.
111
1123.51 Sun Mar 4 14:18:04 CET 2007
113 - fixed a problem when you weakened references to Coro::State's
114 (patch by Yuval Kogman).
115
1163.501 Wed Feb 28 12:44:07 CET 2007
117 - rename some global symbols as macosx from hell redefines
118 them without asking.
119
1203.5 Tue Feb 13 20:22:53 CET 2007
121 - do AnyEvent model detection earlier, avoiding problems
122 caused by first using AnyEvent and later Coro::Event.
123 - implement and document Coro::Event event objects.
124 - fix a potential problem in Coro::Event causing crashes.
125 - initialise PL_comppad when creating a new coroutine,
126 avoids crashes on early coro destruction.
127
1283.41 Mon Jan 22 19:19:49 CET 2007
129 - readline on Coro::Handle did not support undefined $/,
130 nor did it deliver partial lines on EOF or error.
131 - implement malloc fallback for stack allocation because
132 stupid broken idiotic OSX has a stupid broken
133 idiotic fits-the-whole-os mmap "implementation" and
134 my dick feels longer if Coro is portable even to
135 obsolete platforms.
136
1373.4 Fri Jan 19 21:52:54 CET 2007
138 - remove t/09_timer.t, as it isn't really testing much
139 but was rather flaky in practise.
140 - async_pool coro would keep arguments and callback alive until
141 it was reused.
142 - cancellation of a coroutine could cause spurious idle calls
143 in cede_notself.
144
1453.3 Sat Jan 6 03:45:00 CET 2007
7 - implement $coro->on_destroy. 146 - implement $coro->on_destroy.
8 - Coro::Event blocking semantics have been changed, 147 - Coro::Event blocking semantics have been changed,
9 documented and - hopefully - improved. 148 documented and - hopefully - improved.
10 - fix nice adding, not subtracting, from priority. 149 - fix nice adding, not subtracting, from priority.
11 - fix ->prio and api_is_ready (patch by Mark Hinds). 150 - fix ->prio and api_is_ready (patch by Mark Hinds).
12 - fixed an assert ("... == prev__cctx->idle_te") 151 - fixed an assert ("... == prev__cctx->idle_te")
13 that could errronously trigger. 152 that could errronously trigger.
153 - fix various large and small memleaks.
14 - use a (hopefully) more stable cancel implementation 154 - use a (hopefully) more stable cancel implementation
15 that immediately frees the coroutine data. 155 that immediately frees the coroutine data.
156 - cede/cede_notself return a status now.
16 - added Coro::guard function. 157 - added Coro::guard function.
158 - added a global coroutine pool for jobs (on my machine,
159 I can create and execute 48k simple coros/s with async,
160 and 128k coros with async_pool).
161 - Coro::AIO now uses the coroutine priority as io priority.
17 162
183.2 Fri Dec 22 05:07:09 CET 2006 1633.2 Fri Dec 22 05:07:09 CET 2006
