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 8 - fix a file leaking bug in eg/mhyttpd that would allow
9 downloading of any file (reported by oesi).
10 - fix deadlock bug in Coro::Channel (reported by Richard Hundt)
11 (also add testcase).
12 - support Broadcast option in Coro::Socket (patch by Richard Hundt,
13 apparently having loads of fun with that).
14 - implement $state->swap_defsv, ->swap_defav and document ->throw.
15
164.4 Wed Feb 13 16:44:29 CET 2008
17 - only assume .cfi pseudo isns exist on GNU/Linux.
18 - add get_timed method to Coro::Channels.
19 - fixed Coro::Debug manpage.
20 - perl 5.11 compatbility improvement based on patch by
21 Andreas König.
22
234.37 Sun Jan 20 11:25:23 CET 2008
24 - soften the check for an active parser for perl 5.10 (avoiding
25 "Coro::State::transfer called while parsing" in many cases).
26
274.36 Sun Jan 13 10:53:56 CET 2008
28 - reset diehook when terminating from an async_pool as to not
29 trigger any __DIE__ handlers.
30
314.35 Sun Jan 13 04:14:13 CET 2008
32 - "bt" debug command now displays any exceptions
33 from longmess and also skips the innermost
34 stackframes, giving more useufl output.
35 - allow backtraces in coroutines blocked in Coro::EV,
36 at a <1% speed hit.
37 - handle localising of $SIG{__WARN__} and __DIE__
38 properly (with a proper amount of dirty hacking).
39
404.34 Sat Dec 22 17:49:53 CET 2007
41 - upgrade to EV version 2.0 API.
42
434.33 Mon Dec 17 08:36:12 CET 2007
44 - make Coro::AIO etc. loadable in the absence of EV.
45
464.32 Mon Dec 17 07:46:02 CET 2007
47 - majorly improved Coro::Handle's performance with Coro::EV.
48 - implemented the until now mythical Coro::BDB module.
49 - specialcase EV in Coro::AIO and Coro::BDB for extra speed.
50
514.31 Wed Dec 5 12:32:39 CET 2007
52 - remove warn statement form Coro::Util.
53
544.3 Tue Dec 4 20:33:14 CET 2007
55 - calls to the idle function could cause stack corruption
56 when the stack changed.
57 - do no longer rely on the presence of EV::DNS if EV is used
58 (because it is gone), but instead take avdantage of EV::ADNS
59 if available.
60 - add ($) prototypes to all functions in Coro::Storable.
61 - use a conventional (safer) idle callback in Coro::EV.
62 - do accept quickly in Coro::Debug to avoid endless loops.
63
644.22 Fri Nov 30 16:04:04 CET 2007
65 - really use optimised versions for Event and EV in Coro::Util
66 and Coro::Handle.
67
684.21 Sun Nov 25 10:48:59 CET 2007
69 - fix a spurious memory read.
70 - Coro::EV no longer keeps the eventloop "alive".
71
724.2 Fri Nov 9 20:47:05 CET 2007
73 - enable/disable tracing from a new coroutine, not a pooled one.
74 - fix a memleak in Coro::Event.
75 - removed killall call from fork_eval.
76 - made sure store_fd is already loaded so that fork_eval
77 does not have to parse autoload in each subprocess.
78 - only use assembly method if -O switch is in $Config{optimize}.
79 - add (optional) Coro::EV module, so far the best event loop module
80 directly supported by Coro.
81 - if the event model is EV, use EV::DNS to resolve
82 stuff in Coro::Util.
83 - don't get confused by multiple event notifications in Coro::Handle.
84 - initial support for EV (libevent interface).
85 - require Event and EV using configure_requires, to force their existance.
86
874.13 Wed Oct 24 07:26:45 CEST 2007
88 - add Coro::Storable::blocking_thaw.
89 - use a vastly more complicated technique to localise
90 $SIG{__WARN/DIE__} that also works on perls <= 5.8.8.
91 - use a coroutine for the idle callback Coro::Event,
92 instead of running Event in the current coroutine context.
93 This also catches recursive invocations.
94 - actually report fork errors in gethostbyname and inet_aton.
95
964.11 Thu Oct 11 02:40:24 CEST 2007
97 - port to threaded perls.
98
994.1 Thu Oct 11 02:38:16 CEST 2007
100 - incompatible change: $SIG{__DIE__} and $SIG{__WARN__} will now
101 be local to each coro (see Coro::State).
102 - incompatible change: for very deep reasons, cede and cede_notself
103 cannot return anything, so nothing will be returned.
104 - possibly bring back 5.10 compatibility (untested).
105 - work around stupid (and wrong) warning on 5.10 :(.
106 - overlay the saved state over the context stack. This saves
107 a few hundred bytes per coroutine on average and also
108 speeds up context switching a bit.
109 - further tune default stack sizes.
110 - (more) correctly calculate stack usage in coro_rss.
111 - Coro::Storable::blocking_* did not properly lock
112 resulting in races between coroutines.
113 - added Coro::Storable::guard.
114 - stopping to trace a coroutine could destroy the cctx of
115 an unrelated coroutine.
116 - explain the relationship between Perl and C coroutines in
117 more detail in Coro::State.
118 - Coro::Util::inet_aton did not short-circuit dotted quad forms,
119 causing a fork per resolve. This also affected Coro::Socket.
120 - switch to a separate stack in $coro->call/eval to avoid
121 invalidating pointers.
122
1234.03 Sat Oct 6 21:24:00 CEST 2007
124 - added Coro::throw method.
125 - minor code cleanups.
126
1274.02 Sat Oct 6 02:36:47 CEST 2007
128 - fix a very minor per-coroutine memleak (a single codereference).
129 - fixed a bug where the currently in-use c context would be freed
130 prematurely (can happen only when programs change the stacksize
131 or use tracing).
132 - tracing can no longer keep a coro alive after it terminated.
133 - do static branch prediction in the common path for gcc. gives
134 about 2-5% speed improvement here.
135
1364.01 Fri Oct 5 22:10:49 CEST 2007
137 - instead of recreating *a* standard output handle we simply
138 use STDOUT, which is faster and hopefully more robust.
139
1404.0 Fri Oct 5 12:56:00 CEST 2007
141 - incompatibly changed Coro::Storable::freeze.
142 - major new feature: added Coro::Debug, for interactive coroutine
143 debugging, tracing and much more.
144 - major bug fix: unbelievable, but true: $_, $/ and many other
145 "saved" variables actually weren't being saved. This has been fixed,
146 of course, while increasing performance while losing all the save
147 flags.
148 - save flags are gone, and all the api functions dealing with them.
149 - added Coro::Semaphore::adjust.
150 - added Coro::Util::fork_eval.
151 - added Coro::Storable::{nfreeze,blocking_{freeze,nfreeze}}.
152 - added Coro::killall.
153 - reduce initial stack sizes to allow for "micro-coroutines".
154 - better async_pool resource management, moved parts of async_pool
155 handling to XS (major speed improvement).
156 - actually croak before modifying important data structures.
157 - refuse to transfer while compiling.
158 - possibly support eval EXPR better now.
159 - enable assembly per default on linux+bsd x86+amd64.
160 - all internal members were renamed _something for easier subclassing.
161 - many minor tweaks.
162
1633.63 Wed May 16 14:10:06 CEST 2007
164 - implement handcoded assembly for x86/amd64 SVR ABI.
165
1663.62 Fri Apr 27 21:36:06 CEST 2007
167 - upgrade libcoro (which might set unwind info correctly).
168 - change default on linux to setjmp/longjmp.
169
1703.61 Thu Apr 19 12:36:18 CEST 2007
171 - Coro::Storable caused an endless loop when thawing invalid
172 pst's sometimes.
173 - use a Semaphore in Coro::Storable, as Storable doesn't
174 seem to be reentrant (although it is documented to
175 be threadsafe...).
176 - fix Coro::Signal to bring back the original unreliable
177 but stateful semantics.
178 - fixed a lot of typos in Coro.pm (patch submitted by David
179 Steinbrunner, which applied flawlessly).
180
1813.6 Sat Apr 14 17:13:31 CEST 2007
182 - added some bugfixes to get eg/myhttpd working again.
183 - added Coro::Storable for often-cede'ing freeze/thaw.
184 - try to do a clean exit when a coroutine calls exit
185 (EXPERIMENTAL).
186 - got rid of indirect call through _coro_init.
187 - updated the partly antique examples in eg/ to
188 work again and be a bit less magic, too.
189 - fixed Coro::Signal semantics to work as documented again.
190
1913.55 Sun Mar 25 01:20:47 CET 2007
192 - add SAVE_DEFFH to save the default filehandle and enable
193 it by default.
194 - finally move socket-operations from Coro::Socket to Coro::Handle
195 to be able to unblock foreign sockets.
196 - add Coro::State::save_also and guarded_save.
197 - add count accessor to Coro::Semaphore.
198 - add Coro::State::cctx_stacksize.
199 - just for the fun of it, do not rely on implicit context,
200 which can dramatically improve performance, but people
201 using windows-process-emulation perls do not care much about
202 performance.
203
2043.51 Sun Mar 4 14:18:04 CET 2007
205 - fixed a problem when you weakened references to Coro::State's
206 (patch by Yuval Kogman).
207
2083.501 Wed Feb 28 12:44:07 CET 2007
209 - rename some global symbols as macosx from hell redefines
210 them without asking.
211
2123.5 Tue Feb 13 20:22:53 CET 2007
213 - do AnyEvent model detection earlier, avoiding problems
214 caused by first using AnyEvent and later Coro::Event.
215 - implement and document Coro::Event event objects.
216 - fix a potential problem in Coro::Event causing crashes.
217 - initialise PL_comppad when creating a new coroutine,
218 avoids crashes on early coro destruction.
219
2203.41 Mon Jan 22 19:19:49 CET 2007
221 - readline on Coro::Handle did not support undefined $/,
222 nor did it deliver partial lines on EOF or error.
223 - implement malloc fallback for stack allocation because
224 stupid broken idiotic OSX has a stupid broken
225 idiotic fits-the-whole-os mmap "implementation" and
226 my dick feels longer if Coro is portable even to
227 obsolete platforms.
228
2293.4 Fri Jan 19 21:52:54 CET 2007
230 - remove t/09_timer.t, as it isn't really testing much
231 but was rather flaky in practise.
232 - async_pool coro would keep arguments and callback alive until
233 it was reused.
234 - cancellation of a coroutine could cause spurious idle calls
235 in cede_notself.
236
2373.3 Sat Jan 6 03:45:00 CET 2007
7 - implement $coro->on_destroy. 238 - implement $coro->on_destroy.
8 - Coro::Event blocking semantics have been changed, 239 - Coro::Event blocking semantics have been changed,
9 documented and - hopefully - improved. 240 documented and - hopefully - improved.
10 - fix nice adding, not subtracting, from priority. 241 - fix nice adding, not subtracting, from priority.
11 - fix ->prio and api_is_ready (patch by Mark Hinds). 242 - fix ->prio and api_is_ready (patch by Mark Hinds).
17 - cede/cede_notself return a status now. 248 - cede/cede_notself return a status now.
18 - added Coro::guard function. 249 - added Coro::guard function.
19 - added a global coroutine pool for jobs (on my machine, 250 - added a global coroutine pool for jobs (on my machine,
20 I can create and execute 48k simple coros/s with async, 251 I can create and execute 48k simple coros/s with async,
21 and 128k coros with async_pool). 252 and 128k coros with async_pool).
253 - Coro::AIO now uses the coroutine priority as io priority.
22 254
233.2 Fri Dec 22 05:07:09 CET 2006 2553.2 Fri Dec 22 05:07:09 CET 2006
