93.8 8 TODO: AnyEvent provide detetc hook
9 TODO: Coro::AnyEvent
10 - completely reworked the Coro manpage.
11 - added Coro::AnyEvent, generic event loop integration.
12 - implement cancel, ready and kill commands in Coro::Debug.
13 - document find_coro in Coro::Debug.
14 - incompatible change: rename has_stack to has_cctx.
15 - Coro::AIO and Coro::BDB no longer force event model detection.
16
174.6 Sat Apr 26 10:05:14 CEST 2008
18 - INCOMPATIBLE CHANGE: sub/code attributes are no longer supported
19 by the Coro module. It was a mistake to have it in the first place.
20 - (experimental) support for activestate perl 5.10 (method "w").
21 - (experimental) support for strawberry perl (method "a").
22 - coro_sigelem_set did not return a value although it had to,
23 actual impact unknown.
24
254.51 Mon Apr 14 13:28:27 CEST 2008
26 - make it compile again on 5.8.
27
284.50 Thu Apr 10 09:43:17 CEST 2008
29 - I did it twice! (see 4.49).
30
314.49 Sun Apr 6 21:23:31 CEST 2008
32 - grr, instead of compiling the recent changes on 5.10 only they
33 were compiled on 5.8 only.
34
354.48 Sun Apr 6 20:36:46 CEST 2008
36 - allow coroutine switches during eval's under 5.10.x, as it seems
37 the parser is a per-interpreter option now, so this is safe
38 (this might fix the odd crashing bug).
39 - drop support for 5.9.x versions: they are dead, jim.
40
414.47 Sun Apr 6 00:37:52 CEST 2008
42 - force cctx allocation on API calls: we know we need to force one
43 and gcc actually manages to confuse our heuristic nowadays,
44 leading to crashes and worse.
45 - document force_cctx.
46
474.46 Fri Apr 4 22:05:43 CEST 2008
48 - upgrade libcoro, resulting in pthread-backend (which was only created
49 to fulfill the rules of the programming languages shootout).
50
514.45 Thu Mar 13 11:55:36 CET 2008
52 - fix a file leaking bug in eg/mhyttpd that would allow
53 downloading of any file (reported by oesi).
54 - fix deadlock bug in Coro::Channel (reported by Richard Hundt)
55 (also add testcase).
56 - support Broadcast option in Coro::Socket (patch by Richard Hundt,
57 apparently having loads of fun with that).
58 - implement $state->swap_defsv, ->swap_defav and document ->throw.
59
604.4 Wed Feb 13 16:44:29 CET 2008
61 - only assume .cfi pseudo isns exist on GNU/Linux.
62 - add get_timed method to Coro::Channels.
63 - fixed Coro::Debug manpage.
64 - perl 5.11 compatbility improvement based on patch by
65 Andreas König.
66
674.37 Sun Jan 20 11:25:23 CET 2008
68 - soften the check for an active parser for perl 5.10 (avoiding
69 "Coro::State::transfer called while parsing" in many cases).
70
714.36 Sun Jan 13 10:53:56 CET 2008
72 - reset diehook when terminating from an async_pool as to not
73 trigger any __DIE__ handlers.
74
754.35 Sun Jan 13 04:14:13 CET 2008
76 - "bt" debug command now displays any exceptions
77 from longmess and also skips the innermost
78 stackframes, giving more useufl output.
79 - allow backtraces in coroutines blocked in Coro::EV,
80 at a <1% speed hit.
81 - handle localising of $SIG{__WARN__} and __DIE__
82 properly (with a proper amount of dirty hacking).
83
844.34 Sat Dec 22 17:49:53 CET 2007
85 - upgrade to EV version 2.0 API.
86
874.33 Mon Dec 17 08:36:12 CET 2007
88 - make Coro::AIO etc. loadable in the absence of EV.
89
904.32 Mon Dec 17 07:46:02 CET 2007
91 - majorly improved Coro::Handle's performance with Coro::EV.
92 - implemented the until now mythical Coro::BDB module.
93 - specialcase EV in Coro::AIO and Coro::BDB for extra speed.
94
954.31 Wed Dec 5 12:32:39 CET 2007
96 - remove warn statement form Coro::Util.
97
984.3 Tue Dec 4 20:33:14 CET 2007
99 - calls to the idle function could cause stack corruption
100 when the stack changed.
101 - do no longer rely on the presence of EV::DNS if EV is used
102 (because it is gone), but instead take avdantage of EV::ADNS
103 if available.
104 - add ($) prototypes to all functions in Coro::Storable.
105 - use a conventional (safer) idle callback in Coro::EV.
106 - do accept quickly in Coro::Debug to avoid endless loops.
107
1084.22 Fri Nov 30 16:04:04 CET 2007
109 - really use optimised versions for Event and EV in Coro::Util
110 and Coro::Handle.
111
1124.21 Sun Nov 25 10:48:59 CET 2007
113 - fix a spurious memory read.
114 - Coro::EV no longer keeps the eventloop "alive".
115
1164.2 Fri Nov 9 20:47:05 CET 2007
117 - enable/disable tracing from a new coroutine, not a pooled one.
118 - fix a memleak in Coro::Event.
119 - removed killall call from fork_eval.
120 - made sure store_fd is already loaded so that fork_eval
121 does not have to parse autoload in each subprocess.
122 - only use assembly method if -O switch is in $Config{optimize}.
123 - add (optional) Coro::EV module, so far the best event loop module
124 directly supported by Coro.
125 - if the event model is EV, use EV::DNS to resolve
126 stuff in Coro::Util.
127 - don't get confused by multiple event notifications in Coro::Handle.
128 - initial support for EV (libevent interface).
129 - require Event and EV using configure_requires, to force their existance.
130
1314.13 Wed Oct 24 07:26:45 CEST 2007
132 - add Coro::Storable::blocking_thaw.
133 - use a vastly more complicated technique to localise
134 $SIG{__WARN/DIE__} that also works on perls <= 5.8.8.
135 - use a coroutine for the idle callback Coro::Event,
136 instead of running Event in the current coroutine context.
137 This also catches recursive invocations.
138 - actually report fork errors in gethostbyname and inet_aton.
139
1404.11 Thu Oct 11 02:40:24 CEST 2007
141 - port to threaded perls.
142
1434.1 Thu Oct 11 02:38:16 CEST 2007
144 - incompatible change: $SIG{__DIE__} and $SIG{__WARN__} will now
145 be local to each coro (see Coro::State).
146 - incompatible change: for very deep reasons, cede and cede_notself
147 cannot return anything, so nothing will be returned.
148 - possibly bring back 5.10 compatibility (untested).
149 - work around stupid (and wrong) warning on 5.10 :(.
150 - overlay the saved state over the context stack. This saves
151 a few hundred bytes per coroutine on average and also
152 speeds up context switching a bit.
153 - further tune default stack sizes.
154 - (more) correctly calculate stack usage in coro_rss.
155 - Coro::Storable::blocking_* did not properly lock
156 resulting in races between coroutines.
157 - added Coro::Storable::guard.
158 - stopping to trace a coroutine could destroy the cctx of
159 an unrelated coroutine.
160 - explain the relationship between Perl and C coroutines in
161 more detail in Coro::State.
162 - Coro::Util::inet_aton did not short-circuit dotted quad forms,
163 causing a fork per resolve. This also affected Coro::Socket.
164 - switch to a separate stack in $coro->call/eval to avoid
165 invalidating pointers.
166
1674.03 Sat Oct 6 21:24:00 CEST 2007
168 - added Coro::throw method.
169 - minor code cleanups.
170
1714.02 Sat Oct 6 02:36:47 CEST 2007
172 - fix a very minor per-coroutine memleak (a single codereference).
173 - fixed a bug where the currently in-use c context would be freed
174 prematurely (can happen only when programs change the stacksize
175 or use tracing).
176 - tracing can no longer keep a coro alive after it terminated.
177 - do static branch prediction in the common path for gcc. gives
178 about 2-5% speed improvement here.
179
1804.01 Fri Oct 5 22:10:49 CEST 2007
181 - instead of recreating *a* standard output handle we simply
182 use STDOUT, which is faster and hopefully more robust.
183
1844.0 Fri Oct 5 12:56:00 CEST 2007
10 - incompatibly changed Coro::Storable::freeze. 185 - incompatibly changed Coro::Storable::freeze.
11 - major new feature: added Coro::Debug, for interactive coroutine 186 - major new feature: added Coro::Debug, for interactive coroutine
12 debugging, tracing and much more. 187 debugging, tracing and much more.
188 - major bug fix: unbelievable, but true: $_, $/ and many other
189 "saved" variables actually weren't being saved. This has been fixed,
190 of course, while increasing performance while losing all the save
191 flags.
192 - save flags are gone, and all the api functions dealing with them.
13 - added Coro::Semaphore::adjust. 193 - added Coro::Semaphore::adjust.
14 - added Coro::Util::fork_eval. 194 - added Coro::Util::fork_eval.
15 - added Coro::Storable::{nfreeze,blocking_{freeze,nfreeze}}. 195 - added Coro::Storable::{nfreeze,blocking_{freeze,nfreeze}}.
16 - added Coro::killall. 196 - added Coro::killall.
17 - reduce initial stack sizes to allow for "micro-coroutines". 197 - reduce initial stack sizes to allow for "micro-coroutines".
18 - better async_pool resource management, moved parts of async_pool 198 - better async_pool resource management, moved parts of async_pool
19 handling to XS (major speed improvement). 199 handling to XS (major speed improvement).
20 - actually croak before modifying important data structures. 200 - actually croak before modifying important data structures.
21 - refuse to transfer while compiling. 201 - refuse to transfer while compiling.
22 - possibly support eval EXPR better now. 202 - possibly support eval EXPR better now.
23 - enable assembly method per default on linux+bsd x86+amd64. 203 - enable assembly per default on linux+bsd x86+amd64.
204 - all internal members were renamed _something for easier subclassing.
24 - many minor tweaks. 205 - many minor tweaks.
