9 | - INCOMPATIBLE CHANGE: unreferenced coro objects will now be |
|
|
10 | destroyed and cleaned up automatically (e.g. async { schedule }). |
|
|
11 | - Coro::State->is_destroyed is now called is_zombie. |
|
|
12 | - implement a Coro->safe_cancel method that might fail, but |
|
|
13 | cancels in a "safer" way if it succeeds. |
|
|
14 | - get rid of two hash-accesses when initialising a new Coro - this |
|
|
15 | speeds up coro creation by almost a factor of two. |
|
|
16 | - croak when a coro that is being cancelled tries to block |
|
|
17 | (e.g. while executing a guard block), instead of crashing or |
|
|
18 | deadlocking. |
|
|
19 | - use a more robust and also faster method to identify Coro::State |
|
|
20 | objects - speeds up everything a bit. |
|
|
21 | - implement Coro->cancel in XS for a 20% speed improvement, and to |
|
|
22 | be able to implement mutual cancellation. |
|
|
23 | - speed up context switches by a percent or two by more efficiently |
|
|
24 | allocating context stack entries. |
|
|
25 | - implement Coro->join and Coro->on_destroy in XS for a speedup and |
|
|
26 | a reduction in memory use. |
|
|
27 | - cancelling a coro while it itself is cancelling another coro is |
|
|
28 | now supported and working, instead of triggering an assertion. |
|
|
29 | - be a bit more crash-resistant when calling (buggy) on_destroy |
|
|
30 | callbacks (best effort). |
|
|
31 | - move on_destroy into the slf_frame, to allow extension slf |
|
|
32 | functions to have destructors. |
|
|
33 | - get rid if coro refcounting - simply crash in other interpreter |
|
|
34 | threads by nulling the pointers on clone. |
|
|
35 | - simplify warn/die hook handling when loading Coro - the convoluted |
|
|
36 | logic seems to be no longer neccessary. |
|
|
37 | |

|
38 | 5.372 Wed Feb 23 06:14:30 CET 2011 |
|
|
39 | - apparently mingw doesn't provide a working gettimeofday, try to |
|
|
40 | work around that by relying on Time::HiRes (indirectly brought to |
|
|
41 | my attention by Max Maischein). |
|
|
42 | - fix some portability issues when Time::HiRes was used. |
|
|
43 | |
|
|
44 | 5.371 Mon Feb 21 14:36:08 CET 2011 |
|
|
45 | - backport to windows process emulation code again. |
|
|
46 | |
|
|
47 | 5.37 Sat Feb 19 07:49:44 CET 2011 |
|
|
48 | - add a big "Coro thread life cycle" section to "man Coro". |
|
|
49 | - try a tentative workaround against the breakage that 5.13 has |
|
|
50 | introduced without depreciation period. sigh. |
|
|
51 | - no longer use Time::HiRes if gettimeofday is available, which |
|
|
52 | saves quite a lot of memory. |
|
|
53 | |
|
|
54 | 5.36 Sun Feb 13 05:33:41 CET 2011 |
|
|
55 | - automatically load Coro::Channel, Coro::RWLock, Coro::Semaphore, |
|
|
56 | Coro::SemaphoreSet, Coro::Signal and Coro::Specific on first "new" |
|
|
57 | method call. |
|
|
58 | - undocument Coro::Timer::sleep and obsolete whole module. |
|
|
59 | - optimise Coro::Timer::timeout memory and cpu usage. |
|
|
60 | - slightly updated Coro::Intro for recent changes. |
|
|
61 | - do not initialise PL_dirty anymore. |
|
|
62 | |
|
|
63 | 5.25 Thu Nov 11 01:08:39 CET 2010 |
|
|
64 | - try a different approach on netbsd - netbsd 5 finally has marginally |
|
|
65 | working pthreads, but still broken ucontext/sigaltstack. |
|
|
66 | - openbsd 4.8 finally got their act together, Coro works out of the box |
|
|
67 | with asm, setjmp and pthreads (no change, just informational). |
|
|
68 | |
|
|
69 | 5.24 Sat Oct 23 11:27:12 CEST 2010 |
|
|
70 | - port to the EV 4.0 API. |
|
|
71 | - work around bugs in mingw32, making strawberry perl work |
|
|
72 | out of the box. |
|
|
73 | - correctly modify Coro::AIO function prototypes |
|
|
74 | so that they reflect the "no optional parameters" rule. |
|
|
75 | - "ported" libcoro to C++. |
|
|
76 | |
|
|
77 | 5.23 Mon May 17 18:50:42 CEST 2010 |
|
|
78 | - be more resistant to ordering changes when initialising |
|
|
79 | Coro::AnyEvent, Coro::EV and Coro::Event (reported by Matthias |
|
|
80 | Waldorf). |
|
|
81 | - document that perl 5.12 deliberately removed support for cloning. |
|
|
82 | |
|
|
83 | 5.22 Wed Apr 14 03:55:35 CEST 2010 |
|
|
84 | - correctly return udnef on errors in Coro::Handle::read/write |
|
|
85 | (testcase by Marc Mims). |
|
|
86 | - convert Coro::Util into a "perl compatibility wrapper" - the functions |
|
|
87 | are less useful now, but are drop-in replacements for existing |
|
|
88 | functions, listing better alternatives in the documentation. This also |
|
|
89 | fixes a bug in Coro::LWP which naively substituted Socket::inet_aton |
|
|
90 | with Coro::Util::inet_aton. |
|
|
91 | - do not override $Coro::idle unconditionally in Coro.pm, as other |
|
|
92 | modules could have provided their own idle coro already |
|
|
93 | (for exmaple, Coro::AnyEvent). |
|
|
94 | - fix Coro::Util::gethost* functions. |
|
|
95 | - Coro::Timer corretcly exports it's symbols (reported by Hideki Yamamura). |
|
|
96 | |
|
|
97 | 5.21 Wed Dec 16 07:19:51 CET 2009 |
|
|
98 | - automatically load Coro::AnyEvent when AnyEvent and Coro are used |
|
|
99 | together. |
|
|
100 | - add some examples on how to combine other event loops with Coro in |
|
|
101 | Coro::AnyEvent, and how to run it (and not to block). Seems to be |
|
|
102 | the most common source of confusion. |
|
|
103 | - try to catch people naively blocking in an event callback. |
|
|
104 | - work around the perl filehandle bug issue in conjunction with |
|
|
105 | older common::sense (as indirectly pointed out by ZSystem). |
|
|
106 | - clarify the "not from signal handlers" section. |
|
|
107 | |
|
|
108 | 5.2 Sun Oct 4 14:54:24 CEST 2009 |
|
|
109 | - Coro::Storable destroyed the prototypes of the functions it wrapped. |
|
|
110 | - export rouse_cb and rouse_wait by default now. |
|
|
111 | - fix various prototype mismatches in Coro::AnyEvent and Coro::Handle. |
|
|
112 | - new method $state->swap_sv. |
|
|
113 | - added section on "windows process emulation" to the manpage, |
|
|
114 | after a not-so-fruitful (nor-friendly) "discussion" with chip |
|
|
115 | salzenberg (discussion implies arguments, but his only arguments |
|
|
116 | were ad-hominems, one wonders why he started it in the first |
|
|
117 | place). I hope this explains it well enough for him to understand, |
|
|
118 | and maybe well enough for others to understand. |
|
|
119 | - use common::sense everywhere now. |
|
|
120 | - idle callbacks are no longer supported, use idle coros instead. |
|
|
121 | - print a thread listing when a deadlock is detected. |
|
|
122 | |
|
|
123 | 5.17 Sat Aug 22 23:09:31 CEST 2009 |
|
|
124 | - work around a bug in the perl debugger causing crashes |
|
|
125 | when running under the debugger by marking _pool_handler as nodebug. |
|
|
126 | - speed up Coro::async considerably. |
|
|
127 | - try some hacks to get netbsd to work "more often" - their broken |
|
|
128 | setjmp/longjmp, ucontext *and* phtreads are really hard on Coro. |
|
|
129 | - convert Coro to AE 5.0 API. |
|
|
130 | |
|
|
131 | 5.162 Tue Jul 28 04:04:03 CEST 2009 |
|
|
132 | - perl 5.8.2 is now minimum requirement. |
|
|
133 | - skip t/19_handle.t on broken windows perls. |
|
|
134 | |
|
|
135 | 5.161 Wed Jul 22 04:47:38 CEST 2009 |
|
|
136 | - Coro::AnyEvent::poll could have a different prototype when EV was |
|
|
137 | used as backend (analyzed by Tatsuhiko Miyagawa). |
|
|
138 | - Coro::AnyEvent errornously initialised the event loop when loaded, |
|
|
139 | not on demand. |
|
|
140 | - try to workaround rare */t/01_unblock.t failures. |
|
|
141 | |
|
|
142 | 5.16 Tue Jul 21 01:44:37 CEST 2009 |
| 11 | - Coro::AnyEvent failed to hook into the event loop |
143 | - Coro::AnyEvent failed to hook into the event loop |
| 12 | when no threads had been readied between detecting |
144 | when no threads had been readied between detecting |
| 13 | the event loop and actually running it. |
145 | the event loop and actually running it. |
| 14 | - considerably speed up Coro::Select by taking avdantage |
146 | - considerably speed up Coro::Select by taking avdantage |
| 15 | of AnyEvent > 4.8 and some other optimisations. |
147 | of AnyEvent > 4.8 and some other optimisations. |
|
|
148 | - implement paragraph readline mode in Coro::Handle |
|
|
149 | (based on patches by Zsbán Ambrus). |
|
|
150 | - replace WSAEINPROGRESS by WSAEWOULDBLOCK (reported |
|
|
151 | and analyzed by Yasuhiro MATSUMOTO). |
| 16 | - clarified libcoro license and copyright. |
152 | - clarified libcoro license and copyright. |
