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: give some sensible deifnition to running an event loop 4TODO: maybe implement a default message channel, very much like Erlang
5as coroutine with higher priority. 5 (which is cool in a lot of important aspects (failures!),
6 but very lacking in others (higher level ipc)).
6 7
8 - enable/disable tracing from a new coroutine, not a pooled one.
9 - fix a memleak in Coro::Event.
10
114.13 Wed Oct 24 07:26:45 CEST 2007
12 - add Coro::Storable::blocking_thaw.
13 - use a vastly more complicated technique to localise
14 $SIG{__WARN/DIE__} that also works on perls <= 5.8.8.
15 - use a coroutine for the idle callback Coro::Event,
16 instead of running Event in the current coroutine context.
17 This also catches recursive invocations.
18 - actually report fork errors in gethostbyname and inet_aton.
19
204.11 Thu Oct 11 02:40:24 CEST 2007
21 - port to threaded perls.
22
234.1 Thu Oct 11 02:38:16 CEST 2007
24 - incompatible change: $SIG{__DIE__} and $SIG{__WARN__} will now
25 be local to each coro (see Coro::State).
26 - incompatible change: for very deep reasons, cede and cede_notself
27 cannot return anything, so nothing will be returned.
28 - possibly bring back 5.10 compatibility (untested).
29 - work around stupid (and wrong) warning on 5.10 :(.
30 - overlay the saved state over the context stack. This saves
31 a few hundred bytes per coroutine on average and also
32 speeds up context switching a bit.
33 - further tune default stack sizes.
34 - (more) correctly calculate stack usage in coro_rss.
35 - Coro::Storable::blocking_* did not properly lock
36 resulting in races between coroutines.
37 - added Coro::Storable::guard.
38 - stopping to trace a coroutine could destroy the cctx of
39 an unrelated coroutine.
40 - explain the relationship between Perl and C coroutines in
41 more detail in Coro::State.
42 - Coro::Util::inet_aton did not short-circuit dotted quad forms,
43 causing a fork per resolve. This also affected Coro::Socket.
44 - switch to a separate stack in $coro->call/eval to avoid
45 invalidating pointers.
46
474.03 Sat Oct 6 21:24:00 CEST 2007
48 - added Coro::throw method.
49 - minor code cleanups.
50
514.02 Sat Oct 6 02:36:47 CEST 2007
52 - fix a very minor per-coroutine memleak (a single codereference).
53 - fixed a bug where the currently in-use c context would be freed
54 prematurely (can happen only when programs change the stacksize
55 or use tracing).
56 - tracing can no longer keep a coro alive after it terminated.
57 - do static branch prediction in the common path for gcc. gives
58 about 2-5% speed improvement here.
59
604.01 Fri Oct 5 22:10:49 CEST 2007
61 - instead of recreating *a* standard output handle we simply
62 use STDOUT, which is faster and hopefully more robust.
63
644.0 Fri Oct 5 12:56:00 CEST 2007
65 - incompatibly changed Coro::Storable::freeze.
66 - major new feature: added Coro::Debug, for interactive coroutine
67 debugging, tracing and much more.
68 - major bug fix: unbelievable, but true: $_, $/ and many other
69 "saved" variables actually weren't being saved. This has been fixed,
70 of course, while increasing performance while losing all the save
71 flags.
72 - save flags are gone, and all the api functions dealing with them.
73 - added Coro::Semaphore::adjust.
74 - added Coro::Util::fork_eval.
75 - added Coro::Storable::{nfreeze,blocking_{freeze,nfreeze}}.
76 - added Coro::killall.
77 - reduce initial stack sizes to allow for "micro-coroutines".
78 - better async_pool resource management, moved parts of async_pool
79 handling to XS (major speed improvement).
80 - actually croak before modifying important data structures.
81 - refuse to transfer while compiling.
82 - possibly support eval EXPR better now.
83 - enable assembly per default on linux+bsd x86+amd64.
84 - all internal members were renamed _something for easier subclassing.
85 - many minor tweaks.
86
873.63 Wed May 16 14:10:06 CEST 2007
88 - implement handcoded assembly for x86/amd64 SVR ABI.
89
903.62 Fri Apr 27 21:36:06 CEST 2007
91 - upgrade libcoro (which might set unwind info correctly).
92 - change default on linux to setjmp/longjmp.
93
943.61 Thu Apr 19 12:36:18 CEST 2007
95 - Coro::Storable caused an endless loop when thawing invalid
96 pst's sometimes.
97 - use a Semaphore in Coro::Storable, as Storable doesn't
98 seem to be reentrant (although it is documented to
99 be threadsafe...).
100 - fix Coro::Signal to bring back the original unreliable
101 but stateful semantics.
102 - fixed a lot of typos in Coro.pm (patch submitted by David
103 Steinbrunner, which applied flawlessly).
104
1053.6 Sat Apr 14 17:13:31 CEST 2007
106 - added some bugfixes to get eg/myhttpd working again.
107 - added Coro::Storable for often-cede'ing freeze/thaw.
108 - try to do a clean exit when a coroutine calls exit
109 (EXPERIMENTAL).
110 - got rid of indirect call through _coro_init.
111 - updated the partly antique examples in eg/ to
112 work again and be a bit less magic, too.
113 - fixed Coro::Signal semantics to work as documented again.
114
1153.55 Sun Mar 25 01:20:47 CET 2007
116 - add SAVE_DEFFH to save the default filehandle and enable
117 it by default.
118 - finally move socket-operations from Coro::Socket to Coro::Handle
119 to be able to unblock foreign sockets.
120 - add Coro::State::save_also and guarded_save.
121 - add count accessor to Coro::Semaphore.
122 - add Coro::State::cctx_stacksize.
123 - just for the fun of it, do not rely on implicit context,
124 which can dramatically improve performance, but people
125 using windows-process-emulation perls do not care much about
126 performance.
127
1283.51 Sun Mar 4 14:18:04 CET 2007
129 - fixed a problem when you weakened references to Coro::State's
130 (patch by Yuval Kogman).
131
1323.501 Wed Feb 28 12:44:07 CET 2007
133 - rename some global symbols as macosx from hell redefines
134 them without asking.
135
1363.5 Tue Feb 13 20:22:53 CET 2007
137 - do AnyEvent model detection earlier, avoiding problems
138 caused by first using AnyEvent and later Coro::Event.
139 - implement and document Coro::Event event objects.
140 - fix a potential problem in Coro::Event causing crashes.
141 - initialise PL_comppad when creating a new coroutine,
142 avoids crashes on early coro destruction.
143
1443.41 Mon Jan 22 19:19:49 CET 2007
145 - readline on Coro::Handle did not support undefined $/,
146 nor did it deliver partial lines on EOF or error.
147 - implement malloc fallback for stack allocation because
148 stupid broken idiotic OSX has a stupid broken
149 idiotic fits-the-whole-os mmap "implementation" and
150 my dick feels longer if Coro is portable even to
151 obsolete platforms.
152
1533.4 Fri Jan 19 21:52:54 CET 2007
154 - remove t/09_timer.t, as it isn't really testing much
155 but was rather flaky in practise.
156 - async_pool coro would keep arguments and callback alive until
157 it was reused.
158 - cancellation of a coroutine could cause spurious idle calls
159 in cede_notself.
160
1613.3 Sat Jan 6 03:45:00 CET 2007
162 - implement $coro->on_destroy.
163 - Coro::Event blocking semantics have been changed,
164 documented and - hopefully - improved.
7 - fix nice adding, not subtracting, from priority. 165 - fix nice adding, not subtracting, from priority.
8 - fix ->prio and api_is_ready (patch by Mark Hinds). 166 - fix ->prio and api_is_ready (patch by Mark Hinds).
167 - fixed an assert ("... == prev__cctx->idle_te")
168 that could errronously trigger.
169 - fix various large and small memleaks.
170 - use a (hopefully) more stable cancel implementation
171 that immediately frees the coroutine data.
172 - cede/cede_notself return a status now.
173 - added Coro::guard function.
174 - added a global coroutine pool for jobs (on my machine,
175 I can create and execute 48k simple coros/s with async,
176 and 128k coros with async_pool).
177 - Coro::AIO now uses the coroutine priority as io priority.
9 178
103.2 Fri Dec 22 05:07:09 CET 2006 1793.2 Fri Dec 22 05:07:09 CET 2006
11 - improve portability to slightly older perls. 180 - improve portability to slightly older perls.
12 - use cleaner coroutine destruction. 181 - use cleaner coroutine destruction.
13 - simplify configuration for users. 182 - simplify configuration for users.
