|
|
9 | |
|
|
10 | 6.08 Fri Apr 13 12:05:47 CEST 2012 |
|
|
11 | - be more aggressive about exiting like perl does - formerly, |
|
|
12 | exiting from the non-main thread would not execute END blocks. |
|
|
13 | |
|
|
14 | 6.07 Fri Nov 11 21:21:48 CET 2011 |
|
|
15 | - work around a bug in PerlIO (setting $SIG{__WARN__} to a PVCV). |
|
|
16 | - update ecb.h. |
|
|
17 | |
|
|
18 | 6.06 Mon Aug 8 23:59:48 CEST 2011 |
|
|
19 | - cygwin unfortunately patches the stack at runtime, so we use the pthreads |
|
|
20 | backend, which is an order of magnitude slower. unfortunately, cygwins |
|
|
21 | pthread implementation isn't very complete either, so allocate the stack |
|
|
22 | twice just to be sure. |
|
|
23 | (note: cygwin also enables mymalloc, which is NOT THREADSAFE ON WINDOWS, |
|
|
24 | in its ithreaded perl - best recompile cygwin and use the 'w'indows |
|
|
25 | backend for much better performance. also disable ithreads for |
|
|
26 | even better performance...). |
|
|
27 | |
|
|
28 | 6.05 Thu Aug 4 21:36:36 CEST 2011 |
|
|
29 | - blush, condvar values would not be propagated from send to recv anymore |
|
|
30 | (reported by Chip Salzenberg). |
|
|
31 | - use exponential increase for the readline buffer length in |
|
|
32 | Coro::Handle. also reduce initial allocation to 1020 from 4096 bytes. |
|
|
33 | |
|
|
34 | 6.04 Wed Aug 3 17:15:45 CEST 2011 |
|
|
35 | - use even more efficient and more compatible condvars for |
|
|
36 | compatibility to AnyEvent 6.x :) |
|
|
37 | - more inconsequential ecb.h updates. |
|
|
38 | |
|
|
39 | 6.03 Wed Aug 3 11:41:30 CEST 2011 |
|
|
40 | - change how Coro patches AnyEvent condvars for compatibility to |
|
|
41 | AnyEvent 6.x. |
|
|
42 | - update ecb.h, to no longer include <pthread.h> in case WinNT.h |
|
|
43 | hasn't been included. |
|
|
44 | |
|
|
45 | 6.02 Wed Jul 13 04:35:19 CEST 2011 |
|
|
46 | - "improve portability to Gentoo" - gentoo manages to put perl variables |
|
|
47 | in memory areas that are farther than 2gb apart, which the jit couldn't |
|
|
48 | handle and barfed. now it's just a bit slower on gentoo and similar |
|
|
49 | systems. |
|
|
50 | |
|
|
51 | 6.01 Sun Jul 3 12:31:14 CEST 2011 |
|
|
52 | - workarounds are good, but the test for whether pthreads are used |
|
|
53 | was not good. thisone should be better. |
|
|
54 | - check differently whether gcc generates cfi instructions itself. |
|
|
55 | |
|
|
56 | 6.0 Wed Jun 29 19:43:35 CEST 2011 |
|
|
57 | - INCOMPATIBLE CHANGE: unreferenced coro objects will now be |
|
|
58 | destroyed and cleaned up automatically (e.g. async { schedule }). |
|
|
59 | - implement a JIT compiler for part of the thread switch code, |
|
|
60 | which gives a 50% speed improvement on threaded perls, and |
|
|
61 | about 4% on non-thraeded perls (so threaded perls now finally |
|
|
62 | reach about half the speed of non-threaded perls). |
|
|
63 | - slightly modernise Coro::Intro, add section about rouse functions. |
|
|
64 | - avoid DEFSV and ERRSV, giving another 10% improvement |
|
|
65 | in thread switching. |
|
|
66 | - Coro::State->is_destroyed is now called is_zombie. |
|
|
67 | - implement a Coro->safe_cancel method that might fail, but |
|
|
68 | cancels in a "safer" way if it succeeds. |
|
|
69 | - add preliminary support for DEBUGGING perls. |
|
|
70 | - get rid of two hash-accesses when initialising a new Coro - this |
|
|
71 | speeds up coro creation by almost a factor of two. |
|
|
72 | - croak when a coro that is being cancelled tries to block |
|
|
73 | (e.g. while executing a guard block), instead of crashing or |
|
|
74 | deadlocking. |
|
|
75 | - use a more robust and also faster method to identify Coro::State |
|
|
76 | objects - speeds up everything a bit. |
|
|
77 | - implement Coro->cancel in XS for a 20% speed improvement, and to |
|
|
78 | be able to implement mutual cancellation. |
|
|
79 | - speed up context switches by a percent or two by more efficiently |
|
|
80 | allocating context stack entries. |
|
|
81 | - implement Coro->join and Coro->on_destroy in XS for a speedup and |
|
|
82 | a reduction in memory use. |
|
|
83 | - cancelling a coro while it itself is cancelling another coro is |
|
|
84 | now supported and working, instead of triggering an assertion. |
|
|
85 | - be a bit more crash-resistant when calling (buggy) on_destroy |
|
|
86 | callbacks (best effort). |
|
|
87 | - move on_destroy into the slf_frame, to allow extension slf |
|
|
88 | functions to have destructors. |
|
|
89 | - get rid if coro refcounting - simply crash in other interpreter |
|
|
90 | threads by nulling the pointers on clone. |
|
|
91 | - simplify warn/die hook handling when loading Coro - the convoluted |
|
|
92 | logic seems to be no longer neccessary. |
|
|
93 | - use libecb instead of our own home-grown gcc hacks. |
|
|
94 | - document alternatives to Coro::LWP. Please use them :) |
|
|
95 | - work around another mindless idiotic NEEDLESS bug in openbsd/mirbsds |
|
|
96 | sigaltstack. Really. wine suffers from it, erlang suffers from it, |
|
|
97 | and it's known since at least 2006. |
|
|
98 | |
|
|
99 | 5.372 Wed Feb 23 06:14:30 CET 2011 |
|
|
100 | - apparently mingw doesn't provide a working gettimeofday, try to |
|
|
101 | work around that by relying on Time::HiRes (indirectly brought to |
|
|
102 | my attention by Max Maischein). |
|
|
103 | - fix some portability issues when Time::HiRes was used. |
|
|
104 | |
|
|
105 | 5.371 Mon Feb 21 14:36:08 CET 2011 |
|
|
106 | - backport to windows process emulation code again. |
|
|
107 | |
|
|
108 | 5.37 Sat Feb 19 07:49:44 CET 2011 |
|
|
109 | - add a big "Coro thread life cycle" section to "man Coro". |
|
|
110 | - try a tentative workaround against the breakage that 5.13 has |
|
|
111 | introduced without depreciation period. sigh. |
|
|
112 | - no longer use Time::HiRes if gettimeofday is available, which |
|
|
113 | saves quite a lot of memory. |
|
|
114 | |
|
|
115 | 5.36 Sun Feb 13 05:33:41 CET 2011 |
|
|
116 | - automatically load Coro::Channel, Coro::RWLock, Coro::Semaphore, |
|
|
117 | Coro::SemaphoreSet, Coro::Signal and Coro::Specific on first "new" |
|
|
118 | method call. |
|
|
119 | - undocument Coro::Timer::sleep and obsolete whole module. |
|
|
120 | - optimise Coro::Timer::timeout memory and cpu usage. |
|
|
121 | - slightly updated Coro::Intro for recent changes. |
|
|
122 | - do not initialise PL_dirty anymore. |
|
|
123 | |
|
|
124 | 5.25 Thu Nov 11 01:08:39 CET 2010 |
|
|
125 | - try a different approach on netbsd - netbsd 5 finally has marginally |
|
|
126 | working pthreads, but still broken ucontext/sigaltstack. |
|
|
127 | - openbsd 4.8 finally got their act together, Coro works out of the box |
|
|
128 | with asm, setjmp and pthreads (no change, just informational). |
|
|
129 | |
|
|
130 | 5.24 Sat Oct 23 11:27:12 CEST 2010 |
|
|
131 | - port to the EV 4.0 API. |
|
|
132 | - work around bugs in mingw32, making strawberry perl work |
|
|
133 | out of the box. |
|
|
134 | - correctly modify Coro::AIO function prototypes |
|
|
135 | so that they reflect the "no optional parameters" rule. |
|
|
136 | - "ported" libcoro to C++. |
|
|
137 | |
|
|
138 | 5.23 Mon May 17 18:50:42 CEST 2010 |
|
|
139 | - be more resistant to ordering changes when initialising |
|
|
140 | Coro::AnyEvent, Coro::EV and Coro::Event (reported by Matthias |
|
|
141 | Waldorf). |
|
|
142 | - document that perl 5.12 deliberately removed support for cloning. |
|
|
143 | |
|
|
144 | 5.22 Wed Apr 14 03:55:35 CEST 2010 |
|
|
145 | - correctly return udnef on errors in Coro::Handle::read/write |
|
|
146 | (testcase by Marc Mims). |
|
|
147 | - convert Coro::Util into a "perl compatibility wrapper" - the functions |
|
|
148 | are less useful now, but are drop-in replacements for existing |
|
|
149 | functions, listing better alternatives in the documentation. This also |
|
|
150 | fixes a bug in Coro::LWP which naively substituted Socket::inet_aton |
|
|
151 | with Coro::Util::inet_aton. |
|
|
152 | - do not override $Coro::idle unconditionally in Coro.pm, as other |
|
|
153 | modules could have provided their own idle coro already |
|
|
154 | (for exmaple, Coro::AnyEvent). |
|
|
155 | - fix Coro::Util::gethost* functions. |
|
|
156 | - Coro::Timer corretcly exports it's symbols (reported by Hideki Yamamura). |
|
|
157 | |
|
|
158 | 5.21 Wed Dec 16 07:19:51 CET 2009 |
|
|
159 | - automatically load Coro::AnyEvent when AnyEvent and Coro are used |
|
|
160 | together. |
|
|
161 | - add some examples on how to combine other event loops with Coro in |
|
|
162 | Coro::AnyEvent, and how to run it (and not to block). Seems to be |
|
|
163 | the most common source of confusion. |
|
|
164 | - try to catch people naively blocking in an event callback. |
|
|
165 | - work around the perl filehandle bug issue in conjunction with |
|
|
166 | older common::sense (as indirectly pointed out by ZSystem). |
|
|
167 | - clarify the "not from signal handlers" section. |
|
|
168 | |
|
|
169 | 5.2 Sun Oct 4 14:54:24 CEST 2009 |
|
|
170 | - Coro::Storable destroyed the prototypes of the functions it wrapped. |
|
|
171 | - export rouse_cb and rouse_wait by default now. |
|
|
172 | - fix various prototype mismatches in Coro::AnyEvent and Coro::Handle. |
|
|
173 | - new method $state->swap_sv. |
|
|
174 | - added section on "windows process emulation" to the manpage, |
|
|
175 | after a not-so-fruitful (nor-friendly) "discussion" with chip |
|
|
176 | salzenberg (discussion implies arguments, but his only arguments |
|
|
177 | were ad-hominems, one wonders why he started it in the first |
|
|
178 | place). I hope this explains it well enough for him to understand, |
|
|
179 | and maybe well enough for others to understand. |
|
|
180 | - use common::sense everywhere now. |
|
|
181 | - idle callbacks are no longer supported, use idle coros instead. |
|
|
182 | - print a thread listing when a deadlock is detected. |
|
|
183 | |
|
|
184 | 5.17 Sat Aug 22 23:09:31 CEST 2009 |
|
|
185 | - work around a bug in the perl debugger causing crashes |
|
|
186 | when running under the debugger by marking _pool_handler as nodebug. |
|
|
187 | - speed up Coro::async considerably. |
|
|
188 | - try some hacks to get netbsd to work "more often" - their broken |
|
|
189 | setjmp/longjmp, ucontext *and* phtreads are really hard on Coro. |
|
|
190 | - convert Coro to AE 5.0 API. |
|
|
191 | |
|
|
192 | 5.162 Tue Jul 28 04:04:03 CEST 2009 |
|
|
193 | - perl 5.8.2 is now minimum requirement. |
|
|
194 | - skip t/19_handle.t on broken windows perls. |
|
|
195 | |
|
|
196 | 5.161 Wed Jul 22 04:47:38 CEST 2009 |
|
|
197 | - Coro::AnyEvent::poll could have a different prototype when EV was |
|
|
198 | used as backend (analyzed by Tatsuhiko Miyagawa). |
|
|
199 | - Coro::AnyEvent errornously initialised the event loop when loaded, |
|
|
200 | not on demand. |
|
|
201 | - try to workaround rare */t/01_unblock.t failures. |
|
|
202 | |
|
|
203 | 5.16 Tue Jul 21 01:44:37 CEST 2009 |
|
|
204 | - Coro::AnyEvent failed to hook into the event loop |
|
|
205 | when no threads had been readied between detecting |
|
|
206 | the event loop and actually running it. |
|
|
207 | - considerably speed up Coro::Select by taking avdantage |
|
|
208 | of AnyEvent > 4.8 and some other optimisations. |
|
|
209 | - implement paragraph readline mode in Coro::Handle |
|
|
210 | (based on patches by Zsbán Ambrus). |
|
|
211 | - replace WSAEINPROGRESS by WSAEWOULDBLOCK (reported |
|
|
212 | and analyzed by Yasuhiro MATSUMOTO). |
|
|
213 | - clarified libcoro license and copyright. |
|
|
214 | - someone stole my EXTRA_META!!! |
|
|
215 | - implement Coro::Select::patch_pp_sselect and it's brother, |
|
|
216 | for hardcode select overriding. |
|
|
217 | |
|
|
218 | 5.151 Mon Jul 6 05:41:57 CEST 2009 |
|
|
219 | - backport to windows process emulation code again (patch by |
|
|
220 | Yasuhiro MATSUMOTO). |
|
|
221 | - slightly update Coro::MakeMaker. |
|
|
222 | |
|
|
223 | 5.15 Tue Jun 30 10:28:06 CEST 2009 |
|
|
224 | - deprecate Coro::Socket, document how to get ipv6 support via |
|
|
225 | AnyEvent::Socket instead. |
|
|
226 | - implement signal->wait ($cb) interface, similar to semaphores. |
|
|
227 | - work around SvOK not supporting getmagic, so we have to getmagic |
|
|
228 | to test for undef :/ (reported by Matthias Waldorf). |
|
|
229 | - load Coro::AnyEvent in all modules using AnyEvent. |
|
|
230 | - work around perl corrupting our internal data structures, |
|
|
231 | reported by Tokuhiro Matsuno. |
|
|
232 | - enable per-coroutine real and cpu time gathering |
|
|
233 | (Coro::State::enable_times). |
|
|
234 | |
|
|
235 | 5.14 Wed Jun 24 01:37:48 CEST 2009 |
|
|
236 | - provide explicit functions to "cede" to the event loop in Coro::AnyEvent, |
|
|
237 | as this seems to have been a difficult concept (poll, sleep, idle, |
|
|
238 | idle_upto). |
|
|
239 | - add Coro::AnyEvent::readable/writable functions. |
| 11 | - clarify Coro::EV/Event/AnyEvent manpages: you have to actually run |
240 | - clarify Coro::EV/Event/AnyEvent manpages. |
| 12 | the event loop somewhere to be able to poll for events |
241 | - free per-thread global scalars in the thread calling ->cancel, to |
| 13 | in the presence of ready threads. |
242 | avoid crashes when $_, $@ etc., are magical but some of those |
|
|
243 | had already been freed. |
|
|
244 | - "unexperimentalise" the callback interface for Coro::Semaphore. |
| 14 | - speed up ready queue management/context switching by using a linked |
245 | - speed up ready queue management/context switching by using a linked |
| 15 | list instead of an array (~5-10%). |
246 | list instead of an array (~5-10%). |
| 16 | - implement "watch" command in Coro::Debug shells. |
247 | - implement "watch" command in Coro::Debug shells. |
| 17 | - for fun, implement time-slicing as an example in the manpage. |
248 | - for fun, implement time-slicing as an example in the manpage. |
|
|
249 | - if AnyEvent detects EV or Event, but we don't have Coro::EV or |
|
|
250 | Coro::Event, use the normal AnyEvent handling instead of dieing |
|
|
251 | (the same is true for Coro::Handle). |
|
|
252 | - properly document Coro::EV::timed_io_once. |
|
|
253 | - avoid unneccessary ->cancel calls in Coro::Handle. |
|
|
254 | - maybe make it work on mingw32 with win32 backend |
|
|
255 | (based on patch by Yasuhiro Matsumoto). |
| 18 | |
256 | |
| 19 | 5.132 Fri May 29 09:00:39 CEST 2009 |
257 | 5.132 Fri May 29 09:00:39 CEST 2009 |
| 20 | - do not keep a reference to the argument itself in |
258 | - do not keep a reference to the argument itself in |
| 21 | Coro::Semaphore::guard, as it could change later. |
259 | Coro::Semaphore::guard, as it could change later. |
| 22 | - support SO_RCVBUF/SO_SNDBUF nonstandard Coro::Socket options, |
260 | - support SO_RCVBUF/SO_SNDBUF nonstandard Coro::Socket options, |
