84.0 84.49 Sun Apr 6 21:23:31 CEST 2008
9 - grr, instead of compiling the recent changes on 5.10 only they
10 were compiled on 5.8 only.
11
124.48 Sun Apr 6 20:36:46 CEST 2008
13 - allow coroutine switches during eval's under 5.10.x, as it seems
14 the parser is a per-interpreter option now, so this is safe
15 (this might fix the odd crashing bug).
16 - drop support for 5.9.x versions: they are dead, jim.
17
184.47 Sun Apr 6 00:37:52 CEST 2008
19 - force cctx allocation on API calls: we know we need to force one
20 and gcc actually manages to confuse our heuristic nowadays,
21 leading to crashes and worse.
22 - document force_cctx.
23
244.46 Fri Apr 4 22:05:43 CEST 2008
25 - upgrade libcoro, resulting in pthread-backend (which was only created
26 to fulfill the rules of the programming languages shootout).
27
284.45 Thu Mar 13 11:55:36 CET 2008
29 - fix a file leaking bug in eg/mhyttpd that would allow
30 downloading of any file (reported by oesi).
31 - fix deadlock bug in Coro::Channel (reported by Richard Hundt)
32 (also add testcase).
33 - support Broadcast option in Coro::Socket (patch by Richard Hundt,
34 apparently having loads of fun with that).
35 - implement $state->swap_defsv, ->swap_defav and document ->throw.
36
374.4 Wed Feb 13 16:44:29 CET 2008
38 - only assume .cfi pseudo isns exist on GNU/Linux.
39 - add get_timed method to Coro::Channels.
40 - fixed Coro::Debug manpage.
41 - perl 5.11 compatbility improvement based on patch by
42 Andreas König.
43
444.37 Sun Jan 20 11:25:23 CET 2008
45 - soften the check for an active parser for perl 5.10 (avoiding
46 "Coro::State::transfer called while parsing" in many cases).
47
484.36 Sun Jan 13 10:53:56 CET 2008
49 - reset diehook when terminating from an async_pool as to not
50 trigger any __DIE__ handlers.
51
524.35 Sun Jan 13 04:14:13 CET 2008
53 - "bt" debug command now displays any exceptions
54 from longmess and also skips the innermost
55 stackframes, giving more useufl output.
56 - allow backtraces in coroutines blocked in Coro::EV,
57 at a <1% speed hit.
58 - handle localising of $SIG{__WARN__} and __DIE__
59 properly (with a proper amount of dirty hacking).
60
614.34 Sat Dec 22 17:49:53 CET 2007
62 - upgrade to EV version 2.0 API.
63
644.33 Mon Dec 17 08:36:12 CET 2007
65 - make Coro::AIO etc. loadable in the absence of EV.
66
674.32 Mon Dec 17 07:46:02 CET 2007
68 - majorly improved Coro::Handle's performance with Coro::EV.
69 - implemented the until now mythical Coro::BDB module.
70 - specialcase EV in Coro::AIO and Coro::BDB for extra speed.
71
724.31 Wed Dec 5 12:32:39 CET 2007
73 - remove warn statement form Coro::Util.
74
754.3 Tue Dec 4 20:33:14 CET 2007
76 - calls to the idle function could cause stack corruption
77 when the stack changed.
78 - do no longer rely on the presence of EV::DNS if EV is used
79 (because it is gone), but instead take avdantage of EV::ADNS
80 if available.
81 - add ($) prototypes to all functions in Coro::Storable.
82 - use a conventional (safer) idle callback in Coro::EV.
83 - do accept quickly in Coro::Debug to avoid endless loops.
84
854.22 Fri Nov 30 16:04:04 CET 2007
86 - really use optimised versions for Event and EV in Coro::Util
87 and Coro::Handle.
88
894.21 Sun Nov 25 10:48:59 CET 2007
90 - fix a spurious memory read.
91 - Coro::EV no longer keeps the eventloop "alive".
92
934.2 Fri Nov 9 20:47:05 CET 2007
94 - enable/disable tracing from a new coroutine, not a pooled one.
95 - fix a memleak in Coro::Event.
96 - removed killall call from fork_eval.
97 - made sure store_fd is already loaded so that fork_eval
98 does not have to parse autoload in each subprocess.
99 - only use assembly method if -O switch is in $Config{optimize}.
100 - add (optional) Coro::EV module, so far the best event loop module
101 directly supported by Coro.
102 - if the event model is EV, use EV::DNS to resolve
103 stuff in Coro::Util.
104 - don't get confused by multiple event notifications in Coro::Handle.
105 - initial support for EV (libevent interface).
106 - require Event and EV using configure_requires, to force their existance.
107
1084.13 Wed Oct 24 07:26:45 CEST 2007
109 - add Coro::Storable::blocking_thaw.
110 - use a vastly more complicated technique to localise
111 $SIG{__WARN/DIE__} that also works on perls <= 5.8.8.
112 - use a coroutine for the idle callback Coro::Event,
113 instead of running Event in the current coroutine context.
114 This also catches recursive invocations.
115 - actually report fork errors in gethostbyname and inet_aton.
116
1174.11 Thu Oct 11 02:40:24 CEST 2007
118 - port to threaded perls.
119
1204.1 Thu Oct 11 02:38:16 CEST 2007
121 - incompatible change: $SIG{__DIE__} and $SIG{__WARN__} will now
122 be local to each coro (see Coro::State).
123 - incompatible change: for very deep reasons, cede and cede_notself
124 cannot return anything, so nothing will be returned.
125 - possibly bring back 5.10 compatibility (untested).
126 - work around stupid (and wrong) warning on 5.10 :(.
127 - overlay the saved state over the context stack. This saves
128 a few hundred bytes per coroutine on average and also
129 speeds up context switching a bit.
130 - further tune default stack sizes.
131 - (more) correctly calculate stack usage in coro_rss.
132 - Coro::Storable::blocking_* did not properly lock
133 resulting in races between coroutines.
134 - added Coro::Storable::guard.
135 - stopping to trace a coroutine could destroy the cctx of
136 an unrelated coroutine.
137 - explain the relationship between Perl and C coroutines in
138 more detail in Coro::State.
139 - Coro::Util::inet_aton did not short-circuit dotted quad forms,
140 causing a fork per resolve. This also affected Coro::Socket.
141 - switch to a separate stack in $coro->call/eval to avoid
142 invalidating pointers.
143
1444.03 Sat Oct 6 21:24:00 CEST 2007
145 - added Coro::throw method.
146 - minor code cleanups.
147
1484.02 Sat Oct 6 02:36:47 CEST 2007
149 - fix a very minor per-coroutine memleak (a single codereference).
150 - fixed a bug where the currently in-use c context would be freed
151 prematurely (can happen only when programs change the stacksize
152 or use tracing).
153 - tracing can no longer keep a coro alive after it terminated.
154 - do static branch prediction in the common path for gcc. gives
155 about 2-5% speed improvement here.
156
1574.01 Fri Oct 5 22:10:49 CEST 2007
158 - instead of recreating *a* standard output handle we simply
159 use STDOUT, which is faster and hopefully more robust.
160
1614.0 Fri Oct 5 12:56:00 CEST 2007
9 - incompatibly changed Coro::Storable::freeze. 162 - incompatibly changed Coro::Storable::freeze.
10 - major new feature: added Coro::Debug, for interactive coroutine 163 - major new feature: added Coro::Debug, for interactive coroutine
11 debugging, tracing and much more. 164 debugging, tracing and much more.
12 - unbelievable, but true: $_, $@ and many other "saved" variables 165 - major bug fix: unbelievable, but true: $_, $/ and many other
13 actually weren't being saved. This has been fixed, of course, 166 "saved" variables actually weren't being saved. This has been fixed,
14 while increasing performance while losing all the save flags. 167 of course, while increasing performance while losing all the save
168 flags.
15 - save flags are gone, and all the api functions dealing with them. 169 - save flags are gone, and all the api functions dealing with them.
16 - added Coro::Semaphore::adjust. 170 - added Coro::Semaphore::adjust.
17 - added Coro::Util::fork_eval. 171 - added Coro::Util::fork_eval.
18 - added Coro::Storable::{nfreeze,blocking_{freeze,nfreeze}}. 172 - added Coro::Storable::{nfreeze,blocking_{freeze,nfreeze}}.
19 - added Coro::killall. 173 - added Coro::killall.
