93.8 84.51 Mon Apr 14 13:28:27 CEST 2008
9 - make it compile again on 5.8.
10
114.50 Thu Apr 10 09:43:17 CEST 2008
12 - I did it twice! (see 4.49).
13
144.49 Sun Apr 6 21:23:31 CEST 2008
15 - grr, instead of compiling the recent changes on 5.10 only they
16 were compiled on 5.8 only.
17
184.48 Sun Apr 6 20:36:46 CEST 2008
19 - allow coroutine switches during eval's under 5.10.x, as it seems
20 the parser is a per-interpreter option now, so this is safe
21 (this might fix the odd crashing bug).
22 - drop support for 5.9.x versions: they are dead, jim.
23
244.47 Sun Apr 6 00:37:52 CEST 2008
25 - force cctx allocation on API calls: we know we need to force one
26 and gcc actually manages to confuse our heuristic nowadays,
27 leading to crashes and worse.
28 - document force_cctx.
29
304.46 Fri Apr 4 22:05:43 CEST 2008
31 - upgrade libcoro, resulting in pthread-backend (which was only created
32 to fulfill the rules of the programming languages shootout).
33
344.45 Thu Mar 13 11:55:36 CET 2008
35 - fix a file leaking bug in eg/mhyttpd that would allow
36 downloading of any file (reported by oesi).
37 - fix deadlock bug in Coro::Channel (reported by Richard Hundt)
38 (also add testcase).
39 - support Broadcast option in Coro::Socket (patch by Richard Hundt,
40 apparently having loads of fun with that).
41 - implement $state->swap_defsv, ->swap_defav and document ->throw.
42
434.4 Wed Feb 13 16:44:29 CET 2008
44 - only assume .cfi pseudo isns exist on GNU/Linux.
45 - add get_timed method to Coro::Channels.
46 - fixed Coro::Debug manpage.
47 - perl 5.11 compatbility improvement based on patch by
48 Andreas König.
49
504.37 Sun Jan 20 11:25:23 CET 2008
51 - soften the check for an active parser for perl 5.10 (avoiding
52 "Coro::State::transfer called while parsing" in many cases).
53
544.36 Sun Jan 13 10:53:56 CET 2008
55 - reset diehook when terminating from an async_pool as to not
56 trigger any __DIE__ handlers.
57
584.35 Sun Jan 13 04:14:13 CET 2008
59 - "bt" debug command now displays any exceptions
60 from longmess and also skips the innermost
61 stackframes, giving more useufl output.
62 - allow backtraces in coroutines blocked in Coro::EV,
63 at a <1% speed hit.
64 - handle localising of $SIG{__WARN__} and __DIE__
65 properly (with a proper amount of dirty hacking).
66
674.34 Sat Dec 22 17:49:53 CET 2007
68 - upgrade to EV version 2.0 API.
69
704.33 Mon Dec 17 08:36:12 CET 2007
71 - make Coro::AIO etc. loadable in the absence of EV.
72
734.32 Mon Dec 17 07:46:02 CET 2007
74 - majorly improved Coro::Handle's performance with Coro::EV.
75 - implemented the until now mythical Coro::BDB module.
76 - specialcase EV in Coro::AIO and Coro::BDB for extra speed.
77
784.31 Wed Dec 5 12:32:39 CET 2007
79 - remove warn statement form Coro::Util.
80
814.3 Tue Dec 4 20:33:14 CET 2007
82 - calls to the idle function could cause stack corruption
83 when the stack changed.
84 - do no longer rely on the presence of EV::DNS if EV is used
85 (because it is gone), but instead take avdantage of EV::ADNS
86 if available.
87 - add ($) prototypes to all functions in Coro::Storable.
88 - use a conventional (safer) idle callback in Coro::EV.
89 - do accept quickly in Coro::Debug to avoid endless loops.
90
914.22 Fri Nov 30 16:04:04 CET 2007
92 - really use optimised versions for Event and EV in Coro::Util
93 and Coro::Handle.
94
954.21 Sun Nov 25 10:48:59 CET 2007
96 - fix a spurious memory read.
97 - Coro::EV no longer keeps the eventloop "alive".
98
994.2 Fri Nov 9 20:47:05 CET 2007
100 - enable/disable tracing from a new coroutine, not a pooled one.
101 - fix a memleak in Coro::Event.
102 - removed killall call from fork_eval.
103 - made sure store_fd is already loaded so that fork_eval
104 does not have to parse autoload in each subprocess.
105 - only use assembly method if -O switch is in $Config{optimize}.
106 - add (optional) Coro::EV module, so far the best event loop module
107 directly supported by Coro.
108 - if the event model is EV, use EV::DNS to resolve
109 stuff in Coro::Util.
110 - don't get confused by multiple event notifications in Coro::Handle.
111 - initial support for EV (libevent interface).
112 - require Event and EV using configure_requires, to force their existance.
113
1144.13 Wed Oct 24 07:26:45 CEST 2007
115 - add Coro::Storable::blocking_thaw.
116 - use a vastly more complicated technique to localise
117 $SIG{__WARN/DIE__} that also works on perls <= 5.8.8.
118 - use a coroutine for the idle callback Coro::Event,
119 instead of running Event in the current coroutine context.
120 This also catches recursive invocations.
121 - actually report fork errors in gethostbyname and inet_aton.
122
1234.11 Thu Oct 11 02:40:24 CEST 2007
124 - port to threaded perls.
125
1264.1 Thu Oct 11 02:38:16 CEST 2007
127 - incompatible change: $SIG{__DIE__} and $SIG{__WARN__} will now
128 be local to each coro (see Coro::State).
129 - incompatible change: for very deep reasons, cede and cede_notself
130 cannot return anything, so nothing will be returned.
131 - possibly bring back 5.10 compatibility (untested).
132 - work around stupid (and wrong) warning on 5.10 :(.
133 - overlay the saved state over the context stack. This saves
134 a few hundred bytes per coroutine on average and also
135 speeds up context switching a bit.
136 - further tune default stack sizes.
137 - (more) correctly calculate stack usage in coro_rss.
138 - Coro::Storable::blocking_* did not properly lock
139 resulting in races between coroutines.
140 - added Coro::Storable::guard.
141 - stopping to trace a coroutine could destroy the cctx of
142 an unrelated coroutine.
143 - explain the relationship between Perl and C coroutines in
144 more detail in Coro::State.
145 - Coro::Util::inet_aton did not short-circuit dotted quad forms,
146 causing a fork per resolve. This also affected Coro::Socket.
147 - switch to a separate stack in $coro->call/eval to avoid
148 invalidating pointers.
149
1504.03 Sat Oct 6 21:24:00 CEST 2007
151 - added Coro::throw method.
152 - minor code cleanups.
153
1544.02 Sat Oct 6 02:36:47 CEST 2007
155 - fix a very minor per-coroutine memleak (a single codereference).
156 - fixed a bug where the currently in-use c context would be freed
157 prematurely (can happen only when programs change the stacksize
158 or use tracing).
159 - tracing can no longer keep a coro alive after it terminated.
160 - do static branch prediction in the common path for gcc. gives
161 about 2-5% speed improvement here.
162
1634.01 Fri Oct 5 22:10:49 CEST 2007
164 - instead of recreating *a* standard output handle we simply
165 use STDOUT, which is faster and hopefully more robust.
166
1674.0 Fri Oct 5 12:56:00 CEST 2007
10 - incompatibly changed Coro::Storable::freeze. 168 - incompatibly changed Coro::Storable::freeze.
11 - major new feature: added Coro::Debug, for interactive coroutine 169 - major new feature: added Coro::Debug, for interactive coroutine
12 debugging, tracing and much more. 170 debugging, tracing and much more.
171 - major bug fix: unbelievable, but true: $_, $/ and many other
172 "saved" variables actually weren't being saved. This has been fixed,
173 of course, while increasing performance while losing all the save
174 flags.
175 - save flags are gone, and all the api functions dealing with them.
13 - added Coro::Semaphore::adjust. 176 - added Coro::Semaphore::adjust.
14 - added Coro::Util::fork_eval. 177 - added Coro::Util::fork_eval.
15 - added Coro::Storable::{nfreeze,blocking_{freeze,nfreeze}}. 178 - added Coro::Storable::{nfreeze,blocking_{freeze,nfreeze}}.
179 - added Coro::killall.
16 - reduce initial stack sizes to allow for "micro-coroutines". 180 - reduce initial stack sizes to allow for "micro-coroutines".
17 - better async_pool resource management, moved parts of async_pool 181 - better async_pool resource management, moved parts of async_pool
18 handling to XS (major speed improvement). 182 handling to XS (major speed improvement).
19 - actually croak before modifying important data structures. 183 - actually croak before modifying important data structures.
20 - refuse to transfer while compiling. 184 - refuse to transfer while compiling.
21 - possibly support eval EXPR better now. 185 - possibly support eval EXPR better now.
22 - enable assembly method per default on linux+bsd x86+amd64. 186 - enable assembly per default on linux+bsd x86+amd64.
187 - all internal members were renamed _something for easier subclassing.
23 - many minor tweaks. 188 - many minor tweaks.

253.63 Wed May 16 14:10:06 CEST 2007 1903.63 Wed May 16 14:10:06 CEST 2007
