7 (which is cool in a lot of important aspects (failures!), 5 actor model (which is cool in a lot of important aspects (failures!),
8 but very lacking in others). 6 but very lacking in others (higher level ipc)).
9 7
103.7 8 - allow coroutine switches during eval's under 5.10.x, as it seems
9 the parser is a per-interpreter option now, so this is safe
10 (this might fix the odd crashing bug).
11 - drop support for 5.9.x versions, they are dead, jim.
12
134.47 Sun Apr 6 00:37:52 CEST 2008
14 - force cctx allocation on API calls: we know we need to force one
15 and gcc actually manages to confuse our heuristic nowadays,
16 leading to crashes and worse.
17 - document force_cctx.
18
194.46 Fri Apr 4 22:05:43 CEST 2008
20 - upgrade libcoro, resulting in pthread-backend (which was only created
21 to fulfill the rules of the programming languages shootout).
22
234.45 Thu Mar 13 11:55:36 CET 2008
24 - fix a file leaking bug in eg/mhyttpd that would allow
25 downloading of any file (reported by oesi).
26 - fix deadlock bug in Coro::Channel (reported by Richard Hundt)
27 (also add testcase).
28 - support Broadcast option in Coro::Socket (patch by Richard Hundt,
29 apparently having loads of fun with that).
30 - implement $state->swap_defsv, ->swap_defav and document ->throw.
31
324.4 Wed Feb 13 16:44:29 CET 2008
33 - only assume .cfi pseudo isns exist on GNU/Linux.
34 - add get_timed method to Coro::Channels.
35 - fixed Coro::Debug manpage.
36 - perl 5.11 compatbility improvement based on patch by
37 Andreas König.
38
394.37 Sun Jan 20 11:25:23 CET 2008
40 - soften the check for an active parser for perl 5.10 (avoiding
41 "Coro::State::transfer called while parsing" in many cases).
42
434.36 Sun Jan 13 10:53:56 CET 2008
44 - reset diehook when terminating from an async_pool as to not
45 trigger any __DIE__ handlers.
46
474.35 Sun Jan 13 04:14:13 CET 2008
48 - "bt" debug command now displays any exceptions
49 from longmess and also skips the innermost
50 stackframes, giving more useufl output.
51 - allow backtraces in coroutines blocked in Coro::EV,
52 at a <1% speed hit.
53 - handle localising of $SIG{__WARN__} and __DIE__
54 properly (with a proper amount of dirty hacking).
55
564.34 Sat Dec 22 17:49:53 CET 2007
57 - upgrade to EV version 2.0 API.
58
594.33 Mon Dec 17 08:36:12 CET 2007
60 - make Coro::AIO etc. loadable in the absence of EV.
61
624.32 Mon Dec 17 07:46:02 CET 2007
63 - majorly improved Coro::Handle's performance with Coro::EV.
64 - implemented the until now mythical Coro::BDB module.
65 - specialcase EV in Coro::AIO and Coro::BDB for extra speed.
66
674.31 Wed Dec 5 12:32:39 CET 2007
68 - remove warn statement form Coro::Util.
69
704.3 Tue Dec 4 20:33:14 CET 2007
71 - calls to the idle function could cause stack corruption
72 when the stack changed.
73 - do no longer rely on the presence of EV::DNS if EV is used
74 (because it is gone), but instead take avdantage of EV::ADNS
75 if available.
76 - add ($) prototypes to all functions in Coro::Storable.
77 - use a conventional (safer) idle callback in Coro::EV.
78 - do accept quickly in Coro::Debug to avoid endless loops.
79
804.22 Fri Nov 30 16:04:04 CET 2007
81 - really use optimised versions for Event and EV in Coro::Util
82 and Coro::Handle.
83
844.21 Sun Nov 25 10:48:59 CET 2007
85 - fix a spurious memory read.
86 - Coro::EV no longer keeps the eventloop "alive".
87
884.2 Fri Nov 9 20:47:05 CET 2007
89 - enable/disable tracing from a new coroutine, not a pooled one.
90 - fix a memleak in Coro::Event.
91 - removed killall call from fork_eval.
92 - made sure store_fd is already loaded so that fork_eval
93 does not have to parse autoload in each subprocess.
94 - only use assembly method if -O switch is in $Config{optimize}.
95 - add (optional) Coro::EV module, so far the best event loop module
96 directly supported by Coro.
97 - if the event model is EV, use EV::DNS to resolve
98 stuff in Coro::Util.
99 - don't get confused by multiple event notifications in Coro::Handle.
100 - initial support for EV (libevent interface).
101 - require Event and EV using configure_requires, to force their existance.
102
1034.13 Wed Oct 24 07:26:45 CEST 2007
104 - add Coro::Storable::blocking_thaw.
105 - use a vastly more complicated technique to localise
106 $SIG{__WARN/DIE__} that also works on perls <= 5.8.8.
107 - use a coroutine for the idle callback Coro::Event,
108 instead of running Event in the current coroutine context.
109 This also catches recursive invocations.
110 - actually report fork errors in gethostbyname and inet_aton.
111
1124.11 Thu Oct 11 02:40:24 CEST 2007
113 - port to threaded perls.
114
1154.1 Thu Oct 11 02:38:16 CEST 2007
116 - incompatible change: $SIG{__DIE__} and $SIG{__WARN__} will now
117 be local to each coro (see Coro::State).
118 - incompatible change: for very deep reasons, cede and cede_notself
119 cannot return anything, so nothing will be returned.
120 - possibly bring back 5.10 compatibility (untested).
121 - work around stupid (and wrong) warning on 5.10 :(.
122 - overlay the saved state over the context stack. This saves
123 a few hundred bytes per coroutine on average and also
124 speeds up context switching a bit.
125 - further tune default stack sizes.
126 - (more) correctly calculate stack usage in coro_rss.
127 - Coro::Storable::blocking_* did not properly lock
128 resulting in races between coroutines.
129 - added Coro::Storable::guard.
130 - stopping to trace a coroutine could destroy the cctx of
131 an unrelated coroutine.
132 - explain the relationship between Perl and C coroutines in
133 more detail in Coro::State.
134 - Coro::Util::inet_aton did not short-circuit dotted quad forms,
135 causing a fork per resolve. This also affected Coro::Socket.
136 - switch to a separate stack in $coro->call/eval to avoid
137 invalidating pointers.
138
1394.03 Sat Oct 6 21:24:00 CEST 2007
140 - added Coro::throw method.
141 - minor code cleanups.
142
1434.02 Sat Oct 6 02:36:47 CEST 2007
144 - fix a very minor per-coroutine memleak (a single codereference).
145 - fixed a bug where the currently in-use c context would be freed
146 prematurely (can happen only when programs change the stacksize
147 or use tracing).
148 - tracing can no longer keep a coro alive after it terminated.
149 - do static branch prediction in the common path for gcc. gives
150 about 2-5% speed improvement here.
151
1524.01 Fri Oct 5 22:10:49 CEST 2007
153 - instead of recreating *a* standard output handle we simply
154 use STDOUT, which is faster and hopefully more robust.
155
1564.0 Fri Oct 5 12:56:00 CEST 2007
11 - incompatibly changed Coro::Storable::freeze. 157 - incompatibly changed Coro::Storable::freeze.
12 - added Coro::Debug, interactive coroutine debugging. 158 - major new feature: added Coro::Debug, for interactive coroutine
159 debugging, tracing and much more.
160 - major bug fix: unbelievable, but true: $_, $/ and many other
161 "saved" variables actually weren't being saved. This has been fixed,
162 of course, while increasing performance while losing all the save
163 flags.
164 - save flags are gone, and all the api functions dealing with them.
13 - added Coro::Semaphore::adjust. 165 - added Coro::Semaphore::adjust.
14 - added Coro::Util::fork_eval. 166 - added Coro::Util::fork_eval.
15 - added Coro::Storable::{nfreeze,blocking_{freeze,nfreeze}}. 167 - added Coro::Storable::{nfreeze,blocking_{freeze,nfreeze}}.
168 - added Coro::killall.
16 - reduce initial stack sizes to allow for "micro-coroutines". 169 - reduce initial stack sizes to allow for "micro-coroutines".
170 - better async_pool resource management, moved parts of async_pool
171 handling to XS (major speed improvement).
172 - actually croak before modifying important data structures.
173 - refuse to transfer while compiling.
174 - possibly support eval EXPR better now.
175 - enable assembly per default on linux+bsd x86+amd64.
176 - all internal members were renamed _something for easier subclassing.
17 - many minor tweaks. 177 - many minor tweaks.

193.63 Wed May 16 14:10:06 CEST 2007 1793.63 Wed May 16 14:10:06 CEST 2007
20 - implement handcoded assembly for x86/amd64 SVR ABI. 180 - implement handcoded assembly for x86/amd64 SVR ABI.
