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 - fix a spurious memory read.
9
104.2 Fri Nov 9 20:47:05 CET 2007
11 - enable/disable tracing from a new coroutine, not a pooled one.
12 - fix a memleak in Coro::Event.
13 - removed killall call from fork_eval.
14 - made sure store_fd is already loaded so that fork_eval
15 does not have to parse autoload in each subprocess.
16 - only use assembly method if -O switch is in $Config{optimize}.
17 - add (optional) Coro::EV module, so far the best event loop module
18 directly supported by Coro.
19 - if the event model is EV, use EV::DNS to resolve
20 stuff in Coro::Util.
21 - don't get confused by multiple event notifications in Coro::Handle.
22 - initial support for EV (libevent interface).
23 - require Event and EV using configure_requires, to force their existance.
24
254.13 Wed Oct 24 07:26:45 CEST 2007
26 - add Coro::Storable::blocking_thaw.
27 - use a vastly more complicated technique to localise
28 $SIG{__WARN/DIE__} that also works on perls <= 5.8.8.
29 - use a coroutine for the idle callback Coro::Event,
30 instead of running Event in the current coroutine context.
31 This also catches recursive invocations.
32 - actually report fork errors in gethostbyname and inet_aton.
33
344.11 Thu Oct 11 02:40:24 CEST 2007
35 - port to threaded perls.
36
374.1 Thu Oct 11 02:38:16 CEST 2007
38 - incompatible change: $SIG{__DIE__} and $SIG{__WARN__} will now
39 be local to each coro (see Coro::State).
40 - incompatible change: for very deep reasons, cede and cede_notself
41 cannot return anything, so nothing will be returned.
42 - possibly bring back 5.10 compatibility (untested).
43 - work around stupid (and wrong) warning on 5.10 :(.
44 - overlay the saved state over the context stack. This saves
45 a few hundred bytes per coroutine on average and also
46 speeds up context switching a bit.
47 - further tune default stack sizes.
48 - (more) correctly calculate stack usage in coro_rss.
49 - Coro::Storable::blocking_* did not properly lock
50 resulting in races between coroutines.
51 - added Coro::Storable::guard.
52 - stopping to trace a coroutine could destroy the cctx of
53 an unrelated coroutine.
54 - explain the relationship between Perl and C coroutines in
55 more detail in Coro::State.
56 - Coro::Util::inet_aton did not short-circuit dotted quad forms,
57 causing a fork per resolve. This also affected Coro::Socket.
58 - switch to a separate stack in $coro->call/eval to avoid
59 invalidating pointers.
60
614.03 Sat Oct 6 21:24:00 CEST 2007
62 - added Coro::throw method.
63 - minor code cleanups.
64
654.02 Sat Oct 6 02:36:47 CEST 2007
66 - fix a very minor per-coroutine memleak (a single codereference).
67 - fixed a bug where the currently in-use c context would be freed
68 prematurely (can happen only when programs change the stacksize
69 or use tracing).
70 - tracing can no longer keep a coro alive after it terminated.
71 - do static branch prediction in the common path for gcc. gives
72 about 2-5% speed improvement here.
73
744.01 Fri Oct 5 22:10:49 CEST 2007
75 - instead of recreating *a* standard output handle we simply
76 use STDOUT, which is faster and hopefully more robust.
77
784.0 Fri Oct 5 12:56:00 CEST 2007
79 - incompatibly changed Coro::Storable::freeze.
80 - major new feature: added Coro::Debug, for interactive coroutine
81 debugging, tracing and much more.
82 - major bug fix: unbelievable, but true: $_, $/ and many other
83 "saved" variables actually weren't being saved. This has been fixed,
84 of course, while increasing performance while losing all the save
85 flags.
86 - save flags are gone, and all the api functions dealing with them.
87 - added Coro::Semaphore::adjust.
88 - added Coro::Util::fork_eval.
89 - added Coro::Storable::{nfreeze,blocking_{freeze,nfreeze}}.
90 - added Coro::killall.
91 - reduce initial stack sizes to allow for "micro-coroutines".
92 - better async_pool resource management, moved parts of async_pool
93 handling to XS (major speed improvement).
94 - actually croak before modifying important data structures.
95 - refuse to transfer while compiling.
96 - possibly support eval EXPR better now.
97 - enable assembly per default on linux+bsd x86+amd64.
98 - all internal members were renamed _something for easier subclassing.
99 - many minor tweaks.
100
1013.63 Wed May 16 14:10:06 CEST 2007
102 - implement handcoded assembly for x86/amd64 SVR ABI.
103
1043.62 Fri Apr 27 21:36:06 CEST 2007
105 - upgrade libcoro (which might set unwind info correctly).
106 - change default on linux to setjmp/longjmp.
107
1083.61 Thu Apr 19 12:36:18 CEST 2007
109 - Coro::Storable caused an endless loop when thawing invalid
110 pst's sometimes.
111 - use a Semaphore in Coro::Storable, as Storable doesn't
112 seem to be reentrant (although it is documented to
113 be threadsafe...).
114 - fix Coro::Signal to bring back the original unreliable
115 but stateful semantics.
116 - fixed a lot of typos in Coro.pm (patch submitted by David
117 Steinbrunner, which applied flawlessly).
118
1193.6 Sat Apr 14 17:13:31 CEST 2007
120 - added some bugfixes to get eg/myhttpd working again.
121 - added Coro::Storable for often-cede'ing freeze/thaw.
122 - try to do a clean exit when a coroutine calls exit
123 (EXPERIMENTAL).
124 - got rid of indirect call through _coro_init.
125 - updated the partly antique examples in eg/ to
126 work again and be a bit less magic, too.
127 - fixed Coro::Signal semantics to work as documented again.
128
1293.55 Sun Mar 25 01:20:47 CET 2007
130 - add SAVE_DEFFH to save the default filehandle and enable
131 it by default.
132 - finally move socket-operations from Coro::Socket to Coro::Handle
133 to be able to unblock foreign sockets.
134 - add Coro::State::save_also and guarded_save.
135 - add count accessor to Coro::Semaphore.
136 - add Coro::State::cctx_stacksize.
137 - just for the fun of it, do not rely on implicit context,
138 which can dramatically improve performance, but people
139 using windows-process-emulation perls do not care much about
140 performance.
141
1423.51 Sun Mar 4 14:18:04 CET 2007
143 - fixed a problem when you weakened references to Coro::State's
144 (patch by Yuval Kogman).
145
1463.501 Wed Feb 28 12:44:07 CET 2007
147 - rename some global symbols as macosx from hell redefines
148 them without asking.
149
1503.5 Tue Feb 13 20:22:53 CET 2007
151 - do AnyEvent model detection earlier, avoiding problems
152 caused by first using AnyEvent and later Coro::Event.
153 - implement and document Coro::Event event objects.
154 - fix a potential problem in Coro::Event causing crashes.
155 - initialise PL_comppad when creating a new coroutine,
156 avoids crashes on early coro destruction.
157
1583.41 Mon Jan 22 19:19:49 CET 2007
159 - readline on Coro::Handle did not support undefined $/,
160 nor did it deliver partial lines on EOF or error.
161 - implement malloc fallback for stack allocation because
162 stupid broken idiotic OSX has a stupid broken
163 idiotic fits-the-whole-os mmap "implementation" and
164 my dick feels longer if Coro is portable even to
165 obsolete platforms.
166
1673.4 Fri Jan 19 21:52:54 CET 2007
168 - remove t/09_timer.t, as it isn't really testing much
169 but was rather flaky in practise.
170 - async_pool coro would keep arguments and callback alive until
171 it was reused.
172 - cancellation of a coroutine could cause spurious idle calls
173 in cede_notself.
174
1753.3 Sat Jan 6 03:45:00 CET 2007
176 - implement $coro->on_destroy.
177 - Coro::Event blocking semantics have been changed,
178 documented and - hopefully - improved.
7 - fix nice adding, not subtracting, from priority. 179 - fix nice adding, not subtracting, from priority.
8 - fix ->prio and api_is_ready (patch by Mark Hinds). 180 - fix ->prio and api_is_ready (patch by Mark Hinds).
181 - fixed an assert ("... == prev__cctx->idle_te")
182 that could errronously trigger.
183 - fix various large and small memleaks.
184 - use a (hopefully) more stable cancel implementation
185 that immediately frees the coroutine data.
186 - cede/cede_notself return a status now.
187 - added Coro::guard function.
188 - added a global coroutine pool for jobs (on my machine,
189 I can create and execute 48k simple coros/s with async,
190 and 128k coros with async_pool).
191 - Coro::AIO now uses the coroutine priority as io priority.
9 192
103.2 Fri Dec 22 05:07:09 CET 2006 1933.2 Fri Dec 22 05:07:09 CET 2006
11 - improve portability to slightly older perls. 194 - improve portability to slightly older perls.
12 - use cleaner coroutine destruction. 195 - use cleaner coroutine destruction.
13 - simplify configuration for users. 196 - simplify configuration for users.
