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
84.32
9 - majorly improved Coro::Handle's performance with Coro::EV.
10 - implemented the until now mythical Coro::BDB module.
11
124.31 Wed Dec 5 12:32:39 CET 2007
13 - remove warn statement form Coro::Util.
14
154.3 Tue Dec 4 20:33:14 CET 2007
16 - calls to the idle function could cause stack corruption
17 when the stack changed.
18 - do no longer rely on the presence of EV::DNS if EV is used
19 (because it is gone), but instead take avdantage of EV::ADNS
20 if available.
21 - add ($) prototypes to all functions in Coro::Storable.
22 - use a conventional (safer) idle callback in Coro::EV.
23 - do accept quickly in Coro::Debug to avoid endless loops.
24
254.22 Fri Nov 30 16:04:04 CET 2007
26 - really use optimised versions for Event and EV in Coro::Util
27 and Coro::Handle.
28
294.21 Sun Nov 25 10:48:59 CET 2007
30 - fix a spurious memory read.
31 - Coro::EV no longer keeps the eventloop "alive".
32
334.2 Fri Nov 9 20:47:05 CET 2007
34 - enable/disable tracing from a new coroutine, not a pooled one.
35 - fix a memleak in Coro::Event.
36 - removed killall call from fork_eval.
37 - made sure store_fd is already loaded so that fork_eval
38 does not have to parse autoload in each subprocess.
39 - only use assembly method if -O switch is in $Config{optimize}.
40 - add (optional) Coro::EV module, so far the best event loop module
41 directly supported by Coro.
42 - if the event model is EV, use EV::DNS to resolve
43 stuff in Coro::Util.
44 - don't get confused by multiple event notifications in Coro::Handle.
45 - initial support for EV (libevent interface).
46 - require Event and EV using configure_requires, to force their existance.
47
484.13 Wed Oct 24 07:26:45 CEST 2007
49 - add Coro::Storable::blocking_thaw.
50 - use a vastly more complicated technique to localise
51 $SIG{__WARN/DIE__} that also works on perls <= 5.8.8.
52 - use a coroutine for the idle callback Coro::Event,
53 instead of running Event in the current coroutine context.
54 This also catches recursive invocations.
55 - actually report fork errors in gethostbyname and inet_aton.
56
574.11 Thu Oct 11 02:40:24 CEST 2007
58 - port to threaded perls.
59
604.1 Thu Oct 11 02:38:16 CEST 2007
61 - incompatible change: $SIG{__DIE__} and $SIG{__WARN__} will now
62 be local to each coro (see Coro::State).
63 - incompatible change: for very deep reasons, cede and cede_notself
64 cannot return anything, so nothing will be returned.
65 - possibly bring back 5.10 compatibility (untested).
66 - work around stupid (and wrong) warning on 5.10 :(.
67 - overlay the saved state over the context stack. This saves
68 a few hundred bytes per coroutine on average and also
69 speeds up context switching a bit.
70 - further tune default stack sizes.
71 - (more) correctly calculate stack usage in coro_rss.
72 - Coro::Storable::blocking_* did not properly lock
73 resulting in races between coroutines.
74 - added Coro::Storable::guard.
75 - stopping to trace a coroutine could destroy the cctx of
76 an unrelated coroutine.
77 - explain the relationship between Perl and C coroutines in
78 more detail in Coro::State.
79 - Coro::Util::inet_aton did not short-circuit dotted quad forms,
80 causing a fork per resolve. This also affected Coro::Socket.
81 - switch to a separate stack in $coro->call/eval to avoid
82 invalidating pointers.
83
844.03 Sat Oct 6 21:24:00 CEST 2007
85 - added Coro::throw method.
86 - minor code cleanups.
87
884.02 Sat Oct 6 02:36:47 CEST 2007
89 - fix a very minor per-coroutine memleak (a single codereference).
90 - fixed a bug where the currently in-use c context would be freed
91 prematurely (can happen only when programs change the stacksize
92 or use tracing).
93 - tracing can no longer keep a coro alive after it terminated.
94 - do static branch prediction in the common path for gcc. gives
95 about 2-5% speed improvement here.
96
974.01 Fri Oct 5 22:10:49 CEST 2007
98 - instead of recreating *a* standard output handle we simply
99 use STDOUT, which is faster and hopefully more robust.
100
1014.0 Fri Oct 5 12:56:00 CEST 2007
102 - incompatibly changed Coro::Storable::freeze.
103 - major new feature: added Coro::Debug, for interactive coroutine
104 debugging, tracing and much more.
105 - major bug fix: unbelievable, but true: $_, $/ and many other
106 "saved" variables actually weren't being saved. This has been fixed,
107 of course, while increasing performance while losing all the save
108 flags.
109 - save flags are gone, and all the api functions dealing with them.
110 - added Coro::Semaphore::adjust.
111 - added Coro::Util::fork_eval.
112 - added Coro::Storable::{nfreeze,blocking_{freeze,nfreeze}}.
113 - added Coro::killall.
114 - reduce initial stack sizes to allow for "micro-coroutines".
115 - better async_pool resource management, moved parts of async_pool
116 handling to XS (major speed improvement).
117 - actually croak before modifying important data structures.
118 - refuse to transfer while compiling.
119 - possibly support eval EXPR better now.
120 - enable assembly per default on linux+bsd x86+amd64.
121 - all internal members were renamed _something for easier subclassing.
122 - many minor tweaks.
123
1243.63 Wed May 16 14:10:06 CEST 2007
125 - implement handcoded assembly for x86/amd64 SVR ABI.
126
1273.62 Fri Apr 27 21:36:06 CEST 2007
128 - upgrade libcoro (which might set unwind info correctly).
129 - change default on linux to setjmp/longjmp.
130
1313.61 Thu Apr 19 12:36:18 CEST 2007
132 - Coro::Storable caused an endless loop when thawing invalid
133 pst's sometimes.
134 - use a Semaphore in Coro::Storable, as Storable doesn't
135 seem to be reentrant (although it is documented to
136 be threadsafe...).
137 - fix Coro::Signal to bring back the original unreliable
138 but stateful semantics.
139 - fixed a lot of typos in Coro.pm (patch submitted by David
140 Steinbrunner, which applied flawlessly).
141
1423.6 Sat Apr 14 17:13:31 CEST 2007
143 - added some bugfixes to get eg/myhttpd working again.
144 - added Coro::Storable for often-cede'ing freeze/thaw.
145 - try to do a clean exit when a coroutine calls exit
146 (EXPERIMENTAL).
147 - got rid of indirect call through _coro_init.
148 - updated the partly antique examples in eg/ to
149 work again and be a bit less magic, too.
150 - fixed Coro::Signal semantics to work as documented again.
151
1523.55 Sun Mar 25 01:20:47 CET 2007
153 - add SAVE_DEFFH to save the default filehandle and enable
154 it by default.
155 - finally move socket-operations from Coro::Socket to Coro::Handle
156 to be able to unblock foreign sockets.
157 - add Coro::State::save_also and guarded_save.
158 - add count accessor to Coro::Semaphore.
159 - add Coro::State::cctx_stacksize.
160 - just for the fun of it, do not rely on implicit context,
161 which can dramatically improve performance, but people
162 using windows-process-emulation perls do not care much about
163 performance.
164
1653.51 Sun Mar 4 14:18:04 CET 2007
166 - fixed a problem when you weakened references to Coro::State's
167 (patch by Yuval Kogman).
168
1693.501 Wed Feb 28 12:44:07 CET 2007
170 - rename some global symbols as macosx from hell redefines
171 them without asking.
172
1733.5 Tue Feb 13 20:22:53 CET 2007
174 - do AnyEvent model detection earlier, avoiding problems
175 caused by first using AnyEvent and later Coro::Event.
176 - implement and document Coro::Event event objects.
177 - fix a potential problem in Coro::Event causing crashes.
178 - initialise PL_comppad when creating a new coroutine,
179 avoids crashes on early coro destruction.
180
1813.41 Mon Jan 22 19:19:49 CET 2007
182 - readline on Coro::Handle did not support undefined $/,
183 nor did it deliver partial lines on EOF or error.
184 - implement malloc fallback for stack allocation because
185 stupid broken idiotic OSX has a stupid broken
186 idiotic fits-the-whole-os mmap "implementation" and
187 my dick feels longer if Coro is portable even to
188 obsolete platforms.
189
1903.4 Fri Jan 19 21:52:54 CET 2007
6 - remove t/09_timer.t, as it isn't really testing much 191 - remove t/09_timer.t, as it isn't really testing much
7 but was rather flaky in practise. 192 but was rather flaky in practise.
193 - async_pool coro would keep arguments and callback alive until
194 it was reused.
195 - cancellation of a coroutine could cause spurious idle calls
196 in cede_notself.
8 197
93.3 Sat Jan 6 03:45:00 CET 2007 1983.3 Sat Jan 6 03:45:00 CET 2007
10 - implement $coro->on_destroy. 199 - implement $coro->on_destroy.
11 - Coro::Event blocking semantics have been changed, 200 - Coro::Event blocking semantics have been changed,
12 documented and - hopefully - improved. 201 documented and - hopefully - improved.
