9
10 - avoid segfaulting (or worse) when tracing a canceled thread.
11 - the Event module silently broke it's public hook API, causing
12 failures on perls compiled with -Duselongdouble. Requiring
13 the latest version of Event because I don't know which release
14 changed this (it's not mentioned in the ChangeLog).
15 - allow xs level enterleave hooks via CoroAPI.
16
176.43 Thu Jun 4 15:38:14 CEST 2015
18 - use stability canary.
19 - port to stableperl-5.22.0-1.001.
20 - update libecb.
21
226.42 Wed Feb 11 20:29:52 CET 2015
23 - Coro::SemaphoreSet->try did not actually work (analyzed by
24 SATO Kentaro).
25 - upgrade libecb to be C11 compliant.
26
276.41 Sat Sep 6 22:08:46 CEST 2014
28 - restore portability to perl 5.8.x.
29 - give new Coro's a valid GvHV(PL_hintgv) - this is slow and takes
30 up some memory, but fixes "use feature" and similar modules
31 when used inside a Coro.
32 - allow zero as argument to Coro::Channel to mean the same thing
33 as no argument. this works with older versions as well,
34 but wasn't legal until now.
35 - slightly better c header file detection.
36
376.39 Mon Jun 2 00:00:08 CEST 2014
38 - work around more incompatible changes in 5.20.
39
406.38 Sun Jun 1 21:54:23 CEST 2014
41 - check that perl slots actually have enough space to hold
42 interpreter variables.
43 - untested port to perl 5.19 (64 bit tmps indices) (reported
44 by Andreas König).
45 - croak when cancel is called without a thread context.
46
476.37 Tue Mar 4 13:27:33 CET 2014
48 - *sigh*, removed leftover debugging code from debugging a
49 perl bug, of all things.
50
516.36 Tue Mar 4 07:11:59 CET 2014
52 - semaphores would not clear the destroy hook when interrupted
53 by ->throw, causing segfaults or worse.
54 - ->throw on a thread waiting for a semaphore did not acquire
55 the semaphore, but also didn't wake up other waiters,
56 possibly causing a deadlock.
57 - "FATAL: $Coro::IDLE blocked itself" will now use Carp::confess
58 to report a full stacktrace, which should help find out
59 where the actual call is.
60 - "atomically" destroy data in slf_destroy, because it is
61 the right thing to do, just in case.
62 - disable ecb.h libm dependency, to compile on ancient systems
63 or under adverse conditions.
64
656.33 Mon Nov 18 11:26:27 CET 2013
66 - do not crash when freeing padlists with holes (in 5.18).
67 - tentative SVt_BIND 5.19 port/fix.
68
696.32 Tue Nov 5 15:35:35 CET 2013
70 - use a new algorithm to derive padlists for perl 5.18. The old
71 one could lead to 0-pointer accesses inside perl (reported
72 by Darin McBride).
73
746.31 Thu May 9 07:39:48 CEST 2013
75 - Coro::AIO requests would crash if the thread was ready'd
76 while the request was ongoing.
77
786.29 Wed May 8 02:55:18 CEST 2013
79 - when an on_destroy handler destructs the coro currently being
80 destructed a perl scalar could be accessed after being freed,
81 likely causing a crash.
82
836.28 Wed Mar 6 06:58:02 CET 2013
84 - clean remnants of existing __DIE__ and __WARN__ handlers so
85 they lose their magic and will not cause segfaults later
86 (testcase by Andrey Sagulin).
87 - improved Coro::State documentation a bit.
88 - Coro::Debug::command now flushes the output.
89 - add hack detection code for x32 abi, because the braindead slugs
90 who designed that made it look exactly like x86_64 without
91 providing proper compile time symbols to test for it. as a result,
92 this detection cannot work reliably.
93 - valgrind stack registering was broken.
94 - do not rely on Time::HiRes anymore in Coro::Debug.
95
966.23 Fri Dec 7 23:36:37 CET 2012
97 - use experimental fiber implementation on native windows
98 perls.
99 - use sizeof (void *) as multiplication factor for stack sizes,
100 to accomodate the totally braindamaged microsoft 64 bit "os".
101 - changed verifier host from win2k-ap510-32 to win7-sp516-32/64.
102 activeperl 5.16 crashes when PerlIO_define_layer is called due
103 to some bug in the perl dll, strawberry perl at least passes
104 the testsuite.
105 - implement Coro::Handle->peeraddr/host/port, for slightly
106 improved compatibility with LWP.
107 - implement 5.17 compatibility by almost blindly applying a
108 good-looking patch by Father Chrysostomos.
109 - move stack management functions into libcoro 3.
110 - libcoro version 3 "released".
111 - support magic values as timed_io_once args.
112 - recommend AnyEvent 7+ or EV 4+, also require EV
113 version 4 or newer for Coro::EV.
114
1156.10 Tue Oct 9 01:14:27 CEST 2012
116 - updated ecb.h, it had a typo that caused it to not compile on many
117 big endian systems (reported by many people).
118 - disable memory fences in ecb.h to improve portability.
119
1206.09 Sat Oct 6 23:25:02 CEST 2012
121 - Coro::EV I/O watchers were not interruptible by exceptions
122 (Coro::State::throw) (testcase by sten).
123 - ->throw now puts threads into the ready queue, as this seems to
124 be expected by existing code, and code that doesn't cope with spurious
125 wakeups needs fixing anyway.
126 - use fd -1 in mmap.
127 - cast I32 to int in error message printf.
128 - warn about broken so-called "hardened" kernels.
129
1306.08 Fri Apr 13 12:05:47 CEST 2012
131 - be more aggressive about exiting like perl does - formerly,
132 exiting from the non-main thread would not execute END blocks.
133
1346.07 Fri Nov 11 21:21:48 CET 2011
135 - work around a bug in PerlIO (setting $SIG{__WARN__} to a PVCV).
136 - update ecb.h.
137
1386.06 Mon Aug 8 23:59:48 CEST 2011
139 - cygwin unfortunately patches the stack at runtime, so we use the pthreads
140 backend, which is an order of magnitude slower. unfortunately, cygwins
141 pthread implementation isn't very complete either, so allocate the stack
142 twice just to be sure.
143 (note: cygwin also enables mymalloc, which is NOT THREADSAFE ON WINDOWS,
144 in its ithreaded perl - best recompile cygwin and use the 'w'indows
145 backend for much better performance. also disable ithreads for
146 even better performance...).
147
1486.05 Thu Aug 4 21:36:36 CEST 2011
149 - blush, condvar values would not be propagated from send to recv anymore
150 (reported by Chip Salzenberg).
151 - use exponential increase for the readline buffer length in
152 Coro::Handle. also reduce initial allocation to 1020 from 4096 bytes.
153
1546.04 Wed Aug 3 17:15:45 CEST 2011
155 - use even more efficient and more compatible condvars for
156 compatibility to AnyEvent 6.x :)
157 - more inconsequential ecb.h updates.
158
1596.03 Wed Aug 3 11:41:30 CEST 2011
160 - change how Coro patches AnyEvent condvars for compatibility to
161 AnyEvent 6.x.
162 - update ecb.h, to no longer include <pthread.h> in case WinNT.h
163 hasn't been included.
164
1656.02 Wed Jul 13 04:35:19 CEST 2011
166 - "improve portability to Gentoo" - gentoo manages to put perl variables
167 in memory areas that are farther than 2gb apart, which the jit couldn't
168 handle and barfed. now it's just a bit slower on gentoo and similar
169 systems.
170
1716.01 Sun Jul 3 12:31:14 CEST 2011
172 - workarounds are good, but the test for whether pthreads are used
173 was not good. this one should be better.
174 - check differently whether gcc generates cfi instructions itself.
6 175
