6 but very lacking in others (higher level ipc)).
7 6
85.0 7 - add a big "Coro thread life cycle" section to "man Coro".
8 - try a tentative workaround against the breakage that 5.13 has
9 introduced without depreciation period. sigh.
10
115.36 Sun Feb 13 05:33:41 CET 2011
12 - automatically load Coro::Channel, Coro::RWLock, Coro::Semaphore,
13 Coro::SemaphoreSet, Coro::Signal and Coro::Specific on first "new"
14 method call.
15 - undocument Coro::Timer::sleep and obsolete whole module.
16 - optimise Coro::Timer::timeout memory and cpu usage.
17 - slightly updated Coro::Intro for recent changes.
18 - do not initialise PL_dirty anymore.
19
205.25 Thu Nov 11 01:08:39 CET 2010
21 - try a different approach on netbsd - netbsd 5 finally has marginally
22 working pthreads, but still broken ucontext/sigaltstack.
23 - openbsd 4.8 finally got their act together, Coro works out of the box
24 with asm, setjmp and pthreads (no change, just informational).
25
265.24 Sat Oct 23 11:27:12 CEST 2010
27 - port to the EV 4.0 API.
28 - work around bugs in mingw32, making strawberry perl work
29 out of the box.
30 - correctly modify Coro::AIO function prototypes
31 so that they reflect the "no optional parameters" rule.
32 - "ported" libcoro to C++.
33
345.23 Mon May 17 18:50:42 CEST 2010
35 - be more resistant to ordering changes when initialising
36 Coro::AnyEvent, Coro::EV and Coro::Event (reported by Matthias
37 Waldorf).
38 - document that perl 5.12 deliberately removed support for cloning.
39
405.22 Wed Apr 14 03:55:35 CEST 2010
41 - correctly return udnef on errors in Coro::Handle::read/write
42 (testcase by Marc Mims).
43 - convert Coro::Util into a "perl compatibility wrapper" - the functions
44 are less useful now, but are drop-in replacements for existing
45 functions, listing better alternatives in the documentation. This also
46 fixes a bug in Coro::LWP which naively substituted Socket::inet_aton
47 with Coro::Util::inet_aton.
48 - do not override $Coro::idle unconditionally in Coro.pm, as other
49 modules could have provided their own idle coro already
50 (for exmaple, Coro::AnyEvent).
51 - fix Coro::Util::gethost* functions.
52 - Coro::Timer corretcly exports it's symbols (reported by Hideki Yamamura).
53
545.21 Wed Dec 16 07:19:51 CET 2009
55 - automatically load Coro::AnyEvent when AnyEvent and Coro are used
56 together.
57 - add some examples on how to combine other event loops with Coro in
58 Coro::AnyEvent, and how to run it (and not to block). Seems to be
59 the most common source of confusion.
60 - try to catch people naively blocking in an event callback.
61 - work around the perl filehandle bug issue in conjunction with
62 older common::sense (as indirectly pointed out by ZSystem).
63 - clarify the "not from signal handlers" section.
64
655.2 Sun Oct 4 14:54:24 CEST 2009
66 - Coro::Storable destroyed the prototypes of the functions it wrapped.
67 - export rouse_cb and rouse_wait by default now.
68 - fix various prototype mismatches in Coro::AnyEvent and Coro::Handle.
69 - new method $state->swap_sv.
70 - added section on "windows process emulation" to the manpage,
71 after a not-so-fruitful (nor-friendly) "discussion" with chip
72 salzenberg (discussion implies arguments, but his only arguments
73 were ad-hominems, one wonders why he started it in the first
74 place). I hope this explains it well enough for him to understand,
75 and maybe well enough for others to understand.
76 - use common::sense everywhere now.
77 - idle callbacks are no longer supported, use idle coros instead.
78 - print a thread listing when a deadlock is detected.
79
805.17 Sat Aug 22 23:09:31 CEST 2009
81 - work around a bug in the perl debugger causing crashes
82 when running under the debugger by marking _pool_handler as nodebug.
83 - speed up Coro::async considerably.
84 - try some hacks to get netbsd to work "more often" - their broken
85 setjmp/longjmp, ucontext *and* phtreads are really hard on Coro.
86 - convert Coro to AE 5.0 API.
87
885.162 Tue Jul 28 04:04:03 CEST 2009
89 - perl 5.8.2 is now minimum requirement.
90 - skip t/19_handle.t on broken windows perls.
91
925.161 Wed Jul 22 04:47:38 CEST 2009
93 - Coro::AnyEvent::poll could have a different prototype when EV was
94 used as backend (analyzed by Tatsuhiko Miyagawa).
95 - Coro::AnyEvent errornously initialised the event loop when loaded,
96 not on demand.
97 - try to workaround rare */t/01_unblock.t failures.
98
995.16 Tue Jul 21 01:44:37 CEST 2009
100 - Coro::AnyEvent failed to hook into the event loop
101 when no threads had been readied between detecting
102 the event loop and actually running it.
103 - considerably speed up Coro::Select by taking avdantage
104 of AnyEvent > 4.8 and some other optimisations.
105 - implement paragraph readline mode in Coro::Handle
106 (based on patches by Zsbán Ambrus).
107 - replace WSAEINPROGRESS by WSAEWOULDBLOCK (reported
108 and analyzed by Yasuhiro MATSUMOTO).
109 - clarified libcoro license and copyright.
110 - someone stole my EXTRA_META!!!
111 - implement Coro::Select::patch_pp_sselect and it's brother,
112 for hardcode select overriding.
113
1145.151 Mon Jul 6 05:41:57 CEST 2009
115 - backport to windows process emulation code again (patch by
116 Yasuhiro MATSUMOTO).
117 - slightly update Coro::MakeMaker.
118
1195.15 Tue Jun 30 10:28:06 CEST 2009
120 - deprecate Coro::Socket, document how to get ipv6 support via
121 AnyEvent::Socket instead.
122 - implement signal->wait ($cb) interface, similar to semaphores.
123 - work around SvOK not supporting getmagic, so we have to getmagic
124 to test for undef :/ (reported by Matthias Waldorf).
125 - load Coro::AnyEvent in all modules using AnyEvent.
126 - work around perl corrupting our internal data structures,
127 reported by Tokuhiro Matsuno.
128 - enable per-coroutine real and cpu time gathering
129 (Coro::State::enable_times).
130
1315.14 Wed Jun 24 01:37:48 CEST 2009
132 - provide explicit functions to "cede" to the event loop in Coro::AnyEvent,
133 as this seems to have been a difficult concept (poll, sleep, idle,
134 idle_upto).
135 - add Coro::AnyEvent::readable/writable functions.
136 - clarify Coro::EV/Event/AnyEvent manpages.
137 - free per-thread global scalars in the thread calling ->cancel, to
138 avoid crashes when $_, $@ etc., are magical but some of those
139 had already been freed.
140 - "unexperimentalise" the callback interface for Coro::Semaphore.
141 - speed up ready queue management/context switching by using a linked
142 list instead of an array (~5-10%).
143 - implement "watch" command in Coro::Debug shells.
144 - for fun, implement time-slicing as an example in the manpage.
145 - if AnyEvent detects EV or Event, but we don't have Coro::EV or
146 Coro::Event, use the normal AnyEvent handling instead of dieing
147 (the same is true for Coro::Handle).
148 - properly document Coro::EV::timed_io_once.
149 - avoid unneccessary ->cancel calls in Coro::Handle.
150 - maybe make it work on mingw32 with win32 backend
151 (based on patch by Yasuhiro Matsumoto).
152
1535.132 Fri May 29 09:00:39 CEST 2009
154 - do not keep a reference to the argument itself in
155 Coro::Semaphore::guard, as it could change later.
156 - support SO_RCVBUF/SO_SNDBUF nonstandard Coro::Socket options,
157 should support a prepare callback.
158
1595.131 Mon Mar 16 23:20:37 CET 2009
160 - implement and document Coro->suspend, Coro->resume.
161 - fix Coro::Select implementation to not (often) close
162 the passed file descriptors (testcase provided by pippijn).
163
1645.13 Mon Dec 15 21:51:42 CET 2008
165 - EXPERIMENTAL: implement dynamic winds (on_enter/on_leave).
166 - don't set diehook to C<undef> but instead to NULL, to avoid
167 spurious warnings.
168 - fix a lot of bugs in Coro::SemaphoreSet.
169 - Coro::SemaphoreSet will less often create a semaphore needlessly.
170 - add Coro::SemaphoreSet::count and wait methods.
171 - take advantage of the new Guard module.
172 - deprecate Coro::guard.
173 - try to fix the dreaded 01_unblock tests once more. I hate it when
174 testsuites need more fixing than the code they are supposed to test.
175 - croak in more cases when a required callback isn't resolvable.
176 - fix some minor issues in Coro::State->call/eval.
177 - use current coroutine context instead of a temporary one
178 when temporarily switching to another coroutine.
179 - do not call C-level on_destroy handlers during global destruction,
180 to avoid needless segfaults.
181
1825.12 Sun Dec 7 13:30:38 CET 2008
183 - add default config for MirOS, which seems to be a bug-to-bug
184 compatible fork of openbsd ("world domination by releasing
185 openbsd cvs before the openbsd folks do it" or so :).
186 - free_padlist did destroy the names pad, not good, but didn't
187 seem to bother perl - this could fix issues such as eval ""
188 inside a function called from multiple coroutines.
189 - use a different method to detect destruction time.
190 - be more careful when freeing padlists just before global
191 destruction.
192 - fixed and expanded the call/cc example.
193 - renamed _terminate to _coro_run.
194 - new method Coro::Channel->shutdown.
195 - try pthreads on openbsd <4.4 (broken sigaltstack, will
196 pthreads fare better?).
197 - be less picky about destroying "a" running coroutine.
198
1995.11 Tue Nov 25 21:49:05 CET 2008
200 - DEBUGGING in 5.10.0 is a mess: it constantly flags perfectly
201 working code with failed assertions, introducing more bugs than
202 it fixes, requiring elaborate workarounds :(
203
2045.1 Mon Nov 24 08:54:59 CET 2008
205 - wrote a small introductory tutorial - Coro::Intro.
206 - convert Coro::Timer, Coro::Select and Coro::Util to rouse API.
207 - Coro::Select did errornously dup the file descriptors
208 and didn't work with all AnyEvent backends.
209 - Coro::Select wasn't imported correctly form Coro::LWP, causing blocking
210 LWP data transfers.
211 - disassociate c contexts from coro objects - this is agruably more
212 correct, but mostly allows sharing of cctxs between coro and state
213 objects, for added memory savings and speed increases.
214 - bumped $Coro::POOL_RSS up to 32kb by default.
215 - no longer set the optype to OP_CUSTOM, as B::* understandably
216 doesn't like this very much (and we *are* a type of entersub).
217 - implement state cloning, just to prove that call/cc can be done.
218 - automatically load Coro::AnyEvent in Coro::Handle.
219 - wrap ->cancel calls in eval inside Coro::Handle as EV watchers
220 do not have this method (and don't need it either).
221 - speed up generic anyevent methods in Coro::Handle by using rouse
222 callbacks.
223 - allow coroutines in $Coro::IDLE, speeding up Coro::AnyEvent and
224 others. It also makes the debugger happier, as you can trace
225 through the idle threads now.
226 - add comppad_name* and hints ($^H, %^H) to per-thread variables.
227 - eg/event was pretty broken.
228 - better 5.8.6 compatibility.
