9 | - FATAL: $Coro::IDLE blocked itself will now use Carp::confess |
|
|
10 | to report a full stacktrace, which should help find out |
|
|
11 | where the actual call is. |
|
|
12 | |
|
|
13 | 6.33 Mon Nov 18 11:26:27 CET 2013 |
|
|
14 | - do not crash when freeing padlists with holes (in 5.18). |
|
|
15 | - tentative SVt_BIND 5.19 port/fix. |
|
|
16 | |
|
|
17 | 6.32 Tue Nov 5 15:35:35 CET 2013 |
|
|
18 | - use a new algorithm to derive padlists for perl 5.18. The old |
|
|
19 | one could lead to 0-pointer accesses inside perl (reported |
|
|
20 | by Darin McBride). |
|
|
21 | |
|
|
22 | 6.31 Thu May 9 07:39:48 CEST 2013 |
|
|
23 | - Coro::AIO requests would crash if the thread was ready'd |
|
|
24 | while the request was ongoing. |
|
|
25 | |
|
|
26 | 6.29 Wed May 8 02:55:18 CEST 2013 |
|
|
27 | - when an on_destroy handler destructs the coro currently being |
|
|
28 | destructed a perl scalar could be accessed after being freed, |
|
|
29 | likely causing a crash. |
|
|
30 | |
|
|
31 | 6.28 Wed Mar 6 06:58:02 CET 2013 |
|
|
32 | - clean remnants of existing __DIE__ and __WARN__ handlers so |
|
|
33 | they lose their magic and will not cause segfaults later |
|
|
34 | (testcase by Andrey Sagulin). |
|
|
35 | - improved Coro::State documentation a bit. |
|
|
36 | - Coro::Debug::command now flushes the output. |
|
|
37 | - add hack detection code for x32 abi, because the braindead slugs |
|
|
38 | who designed that made it look exactly like x86_64 without |
|
|
39 | providing proper compile time symbols to test for it. as a result, |
|
|
40 | this detection cannot work reliably. |
|
|
41 | - valgrind stack registering was broken. |
|
|
42 | - do not rely on Time::HiRes anymore in Coro::Debug. |
|
|
43 | |
|
|
44 | 6.23 Fri Dec 7 23:36:37 CET 2012 |
|
|
45 | - use experimental fiber implementation on native windows |
|
|
46 | perls. |
|
|
47 | - use sizeof (void *) as multiplication factor for stack sizes, |
|
|
48 | to accomodate the totally braindamaged microsoft 64 bit "os". |
|
|
49 | - changed verifier host from win2k-ap510-32 to win7-sp516-32/64. |
|
|
50 | activeperl 5.16 crashes when PerlIO_define_layer is called due |
|
|
51 | to some bug in the perl dll, strawberry perl at least passes |
|
|
52 | the testsuite. |
|
|
53 | - implement Coro::Handle->peeraddr/host/port, for slightly |
|
|
54 | improved compatibility with LWP. |
|
|
55 | - implement 5.17 compatibility by almost blindly applying a |
|
|
56 | good-looking patch by Father Chrysostomos. |
|
|
57 | - move stack management functions into libcoro 3. |
|
|
58 | - libcoro version 3 "released". |
|
|
59 | - support magic values as timed_io_once args. |
|
|
60 | - recommend AnyEvent 7+ or EV 4+, also require EV |
|
|
61 | version 4 or newer for Coro::EV. |
|
|
62 | |
|
|
63 | 6.10 Tue Oct 9 01:14:27 CEST 2012 |
|
|
64 | - updated ecb.h, it had a typo that caused it to not compile on many |
|
|
65 | big endian systems (reported by many people). |
|
|
66 | - disable memory fences in ecb.h to improve portability. |
|
|
67 | |
|
|
68 | 6.09 Sat Oct 6 23:25:02 CEST 2012 |
|
|
69 | - Coro::EV I/O watchers were not interruptible by exceptions |
|
|
70 | (Coro::State::throw) (testcase by sten). |
|
|
71 | - ->throw now puts threads into the ready queue, as this seems to |
|
|
72 | be expected by existing code, and code that doesn't cope with spurious |
|
|
73 | wakeups needs fixing anyway. |
|
|
74 | - use fd -1 in mmap. |
|
|
75 | - cast I32 to int in error message printf. |
|
|
76 | - warn about broken so-called "hardened" kernels. |
|
|
77 | |
|
|
78 | 6.08 Fri Apr 13 12:05:47 CEST 2012 |
|
|
79 | - be more aggressive about exiting like perl does - formerly, |
|
|
80 | exiting from the non-main thread would not execute END blocks. |
|
|
81 | |
|
|
82 | 6.07 Fri Nov 11 21:21:48 CET 2011 |
|
|
83 | - work around a bug in PerlIO (setting $SIG{__WARN__} to a PVCV). |
|
|
84 | - update ecb.h. |
|
|
85 | |
|
|
86 | 6.06 Mon Aug 8 23:59:48 CEST 2011 |
|
|
87 | - cygwin unfortunately patches the stack at runtime, so we use the pthreads |
|
|
88 | backend, which is an order of magnitude slower. unfortunately, cygwins |
|
|
89 | pthread implementation isn't very complete either, so allocate the stack |
|
|
90 | twice just to be sure. |
|
|
91 | (note: cygwin also enables mymalloc, which is NOT THREADSAFE ON WINDOWS, |
|
|
92 | in its ithreaded perl - best recompile cygwin and use the 'w'indows |
|
|
93 | backend for much better performance. also disable ithreads for |
|
|
94 | even better performance...). |
|
|
95 | |
|
|
96 | 6.05 Thu Aug 4 21:36:36 CEST 2011 |
|
|
97 | - blush, condvar values would not be propagated from send to recv anymore |
|
|
98 | (reported by Chip Salzenberg). |
|
|
99 | - use exponential increase for the readline buffer length in |
|
|
100 | Coro::Handle. also reduce initial allocation to 1020 from 4096 bytes. |
|
|
101 | |
|
|
102 | 6.04 Wed Aug 3 17:15:45 CEST 2011 |
|
|
103 | - use even more efficient and more compatible condvars for |
|
|
104 | compatibility to AnyEvent 6.x :) |
|
|
105 | - more inconsequential ecb.h updates. |
|
|
106 | |
|
|
107 | 6.03 Wed Aug 3 11:41:30 CEST 2011 |
|
|
108 | - change how Coro patches AnyEvent condvars for compatibility to |
|
|
109 | AnyEvent 6.x. |
|
|
110 | - update ecb.h, to no longer include <pthread.h> in case WinNT.h |
|
|
111 | hasn't been included. |
|
|
112 | |
|
|
113 | 6.02 Wed Jul 13 04:35:19 CEST 2011 |
|
|
114 | - "improve portability to Gentoo" - gentoo manages to put perl variables |
|
|
115 | in memory areas that are farther than 2gb apart, which the jit couldn't |
|
|
116 | handle and barfed. now it's just a bit slower on gentoo and similar |
|
|
117 | systems. |
|
|
118 | |
|
|
119 | 6.01 Sun Jul 3 12:31:14 CEST 2011 |
|
|
120 | - workarounds are good, but the test for whether pthreads are used |
|
|
121 | was not good. thisone should be better. |
|
|
122 | - check differently whether gcc generates cfi instructions itself. |
|
|
123 | |
|
|
124 | 6.0 Wed Jun 29 19:43:35 CEST 2011 |
|
|
125 | - INCOMPATIBLE CHANGE: unreferenced coro objects will now be |
|
|
126 | destroyed and cleaned up automatically (e.g. async { schedule }). |
|
|
127 | - implement a JIT compiler for part of the thread switch code, |
|
|
128 | which gives a 50% speed improvement on threaded perls, and |
|
|
129 | about 4% on non-thraeded perls (so threaded perls now finally |
|
|
130 | reach about half the speed of non-threaded perls). |
|
|
131 | - slightly modernise Coro::Intro, add section about rouse functions. |
|
|
132 | - avoid DEFSV and ERRSV, giving another 10% improvement |
|
|
133 | in thread switching. |
|
|
134 | - Coro::State->is_destroyed is now called is_zombie. |
|
|
135 | - implement a Coro->safe_cancel method that might fail, but |
|
|
136 | cancels in a "safer" way if it succeeds. |
|
|
137 | - add preliminary support for DEBUGGING perls. |
|
|
138 | - get rid of two hash-accesses when initialising a new Coro - this |
|
|
139 | speeds up coro creation by almost a factor of two. |
|
|
140 | - croak when a coro that is being cancelled tries to block |
|
|
141 | (e.g. while executing a guard block), instead of crashing or |
|
|
142 | deadlocking. |
|
|
143 | - use a more robust and also faster method to identify Coro::State |
|
|
144 | objects - speeds up everything a bit. |
|
|
145 | - implement Coro->cancel in XS for a 20% speed improvement, and to |
|
|
146 | be able to implement mutual cancellation. |
|
|
147 | - speed up context switches by a percent or two by more efficiently |
|
|
148 | allocating context stack entries. |
|
|
149 | - implement Coro->join and Coro->on_destroy in XS for a speedup and |
|
|
150 | a reduction in memory use. |
|
|
151 | - cancelling a coro while it itself is cancelling another coro is |
|
|
152 | now supported and working, instead of triggering an assertion. |
|
|
153 | - be a bit more crash-resistant when calling (buggy) on_destroy |
|
|
154 | callbacks (best effort). |
|
|
155 | - move on_destroy into the slf_frame, to allow extension slf |
|
|
156 | functions to have destructors. |
|
|
157 | - get rid if coro refcounting - simply crash in other interpreter |
|
|
158 | threads by nulling the pointers on clone. |
|
|
159 | - simplify warn/die hook handling when loading Coro - the convoluted |
|
|
160 | logic seems to be no longer neccessary. |
|
|
161 | - use libecb instead of our own home-grown gcc hacks. |
|
|
162 | - document alternatives to Coro::LWP. Please use them :) |
|
|
163 | - work around another mindless idiotic NEEDLESS bug in openbsd/mirbsds |
|
|
164 | sigaltstack. Really. wine suffers from it, erlang suffers from it, |
|
|
165 | and it's known since at least 2006. |
|
|
166 | |
|
|
167 | 5.372 Wed Feb 23 06:14:30 CET 2011 |
|
|
168 | - apparently mingw doesn't provide a working gettimeofday, try to |
|
|
169 | work around that by relying on Time::HiRes (indirectly brought to |
|
|
170 | my attention by Max Maischein). |
|
|
171 | - fix some portability issues when Time::HiRes was used. |
|
|
172 | |
|
|
173 | 5.371 Mon Feb 21 14:36:08 CET 2011 |
|
|
174 | - backport to windows process emulation code again. |
|
|
175 | |
|
|
176 | 5.37 Sat Feb 19 07:49:44 CET 2011 |
