12 - bump minimum perl version to 5.10.
13
146.48 Sun Oct 4 19:03:51 CEST 2015
15 - fix memory leak when Coro::Handle uses Coro::EV internally
16 (testcase by Sten Sten).
17 - update code to libev 4 API (internally, Coro still used the
18 version 3 API calls).
19 - remove unused hv_sig.
20
216.47 Sat Jul 11 03:58:20 CEST 2015
22 - swap_svs - NVs can be in the SV head beginning with 5.20.
23
246.46 Tue Jun 30 14:36:30 CEST 2015
25 - restore portability to perls with windows fork emulation
26 (patch by Petr Písař).
27
286.45 Tue Jun 30 01:40:08 CEST 2015
29 - restore portability to perl 5.16 and below.
30
316.44 Tue Jun 30 00:41:54 CEST 2015
32 - avoid segfaulting (or worse) when tracing a canceled thread.
33 - the Event module silently broke it's public hook API, causing
34 failures on perls compiled with -Duselongdouble. Requiring
35 the latest version of Event because I don't know which release
36 changed this (it's not mentioned in the ChangeLog).
37 - allow xs level enterleave hooks via CoroAPI.
38
396.43 Thu Jun 4 15:38:14 CEST 2015
40 - use stability canary.
41 - port to stableperl-5.22.0-1.001.
42 - update libecb.
43
446.42 Wed Feb 11 20:29:52 CET 2015
45 - Coro::SemaphoreSet->try did not actually work (analyzed by
46 SATO Kentaro).
47 - upgrade libecb to be C11 compliant.
48
496.41 Sat Sep 6 22:08:46 CEST 2014
50 - restore portability to perl 5.8.x.
51 - give new Coro's a valid GvHV(PL_hintgv) - this is slow and takes
52 up some memory, but fixes "use feature" and similar modules
53 when used inside a Coro.
54 - allow zero as argument to Coro::Channel to mean the same thing
55 as no argument. this works with older versions as well,
56 but wasn't legal until now.
57 - slightly better c header file detection.
58
596.39 Mon Jun 2 00:00:08 CEST 2014
60 - work around more incompatible changes in 5.20.
61
626.38 Sun Jun 1 21:54:23 CEST 2014
63 - check that perl slots actually have enough space to hold
64 interpreter variables.
65 - untested port to perl 5.19 (64 bit tmps indices) (reported
66 by Andreas König).
67 - croak when cancel is called without a thread context.
68
696.37 Tue Mar 4 13:27:33 CET 2014
70 - *sigh*, removed leftover debugging code from debugging a
71 perl bug, of all things.
72
736.36 Tue Mar 4 07:11:59 CET 2014
74 - semaphores would not clear the destroy hook when interrupted
75 by ->throw, causing segfaults or worse.
76 - ->throw on a thread waiting for a semaphore did not acquire
77 the semaphore, but also didn't wake up other waiters,
78 possibly causing a deadlock.
79 - "FATAL: $Coro::IDLE blocked itself" will now use Carp::confess
80 to report a full stacktrace, which should help find out
81 where the actual call is.
82 - "atomically" destroy data in slf_destroy, because it is
83 the right thing to do, just in case.
84 - disable ecb.h libm dependency, to compile on ancient systems
85 or under adverse conditions.
86
876.33 Mon Nov 18 11:26:27 CET 2013
88 - do not crash when freeing padlists with holes (in 5.18).
89 - tentative SVt_BIND 5.19 port/fix.
90
916.32 Tue Nov 5 15:35:35 CET 2013
92 - use a new algorithm to derive padlists for perl 5.18. The old
93 one could lead to 0-pointer accesses inside perl (reported
94 by Darin McBride).
95
966.31 Thu May 9 07:39:48 CEST 2013
97 - Coro::AIO requests would crash if the thread was ready'd
98 while the request was ongoing.
99
1006.29 Wed May 8 02:55:18 CEST 2013
101 - when an on_destroy handler destructs the coro currently being
102 destructed a perl scalar could be accessed after being freed,
103 likely causing a crash.
104
1056.28 Wed Mar 6 06:58:02 CET 2013
106 - clean remnants of existing __DIE__ and __WARN__ handlers so
107 they lose their magic and will not cause segfaults later
108 (testcase by Andrey Sagulin).
109 - improved Coro::State documentation a bit.
110 - Coro::Debug::command now flushes the output.
111 - add hack detection code for x32 abi, because the braindead slugs
112 who designed that made it look exactly like x86_64 without
113 providing proper compile time symbols to test for it. as a result,
114 this detection cannot work reliably.
115 - valgrind stack registering was broken.
116 - do not rely on Time::HiRes anymore in Coro::Debug.
117
1186.23 Fri Dec 7 23:36:37 CET 2012
119 - use experimental fiber implementation on native windows
120 perls.
121 - use sizeof (void *) as multiplication factor for stack sizes,
122 to accomodate the totally braindamaged microsoft 64 bit "os".
123 - changed verifier host from win2k-ap510-32 to win7-sp516-32/64.
124 activeperl 5.16 crashes when PerlIO_define_layer is called due
125 to some bug in the perl dll, strawberry perl at least passes
126 the testsuite.
127 - implement Coro::Handle->peeraddr/host/port, for slightly
128 improved compatibility with LWP.
129 - implement 5.17 compatibility by almost blindly applying a
130 good-looking patch by Father Chrysostomos.
131 - move stack management functions into libcoro 3.
132 - libcoro version 3 "released".
133 - support magic values as timed_io_once args.
134 - recommend AnyEvent 7+ or EV 4+, also require EV
135 version 4 or newer for Coro::EV.
136
1376.10 Tue Oct 9 01:14:27 CEST 2012
138 - updated ecb.h, it had a typo that caused it to not compile on many
139 big endian systems (reported by many people).
140 - disable memory fences in ecb.h to improve portability.
141
1426.09 Sat Oct 6 23:25:02 CEST 2012
143 - Coro::EV I/O watchers were not interruptible by exceptions
144 (Coro::State::throw) (testcase by sten).
145 - ->throw now puts threads into the ready queue, as this seems to
146 be expected by existing code, and code that doesn't cope with spurious
147 wakeups needs fixing anyway.
148 - use fd -1 in mmap.
149 - cast I32 to int in error message printf.
150 - warn about broken so-called "hardened" kernels.
151
1526.08 Fri Apr 13 12:05:47 CEST 2012
153 - be more aggressive about exiting like perl does - formerly,
154 exiting from the non-main thread would not execute END blocks.
155
1566.07 Fri Nov 11 21:21:48 CET 2011
157 - work around a bug in PerlIO (setting $SIG{__WARN__} to a PVCV).
158 - update ecb.h.
159
1606.06 Mon Aug 8 23:59:48 CEST 2011
161 - cygwin unfortunately patches the stack at runtime, so we use the pthreads
162 backend, which is an order of magnitude slower. unfortunately, cygwins
163 pthread implementation isn't very complete either, so allocate the stack
164 twice just to be sure.
165 (note: cygwin also enables mymalloc, which is NOT THREADSAFE ON WINDOWS,
166 in its ithreaded perl - best recompile cygwin and use the 'w'indows
167 backend for much better performance. also disable ithreads for
168 even better performance...).
169
1706.05 Thu Aug 4 21:36:36 CEST 2011
171 - blush, condvar values would not be propagated from send to recv anymore
172 (reported by Chip Salzenberg).
173 - use exponential increase for the readline buffer length in
174 Coro::Handle. also reduce initial allocation to 1020 from 4096 bytes.
175
1766.04 Wed Aug 3 17:15:45 CEST 2011
177 - use even more efficient and more compatible condvars for
178 compatibility to AnyEvent 6.x :)
179 - more inconsequential ecb.h updates.
180
1816.03 Wed Aug 3 11:41:30 CEST 2011
182 - change how Coro patches AnyEvent condvars for compatibility to
183 AnyEvent 6.x.
184 - update ecb.h, to no longer include <pthread.h> in case WinNT.h
185 hasn't been included.
186
1876.02 Wed Jul 13 04:35:19 CEST 2011
188 - "improve portability to Gentoo" - gentoo manages to put perl variables
189 in memory areas that are farther than 2gb apart, which the jit couldn't
190 handle and barfed. now it's just a bit slower on gentoo and similar
191 systems.
192
1936.01 Sun Jul 3 12:31:14 CEST 2011
194 - workarounds are good, but the test for whether pthreads are used
195 was not good. this one should be better.
196 - check differently whether gcc generates cfi instructions itself.
197
1986.0 Wed Jun 29 19:43:35 CEST 2011

10 destroyed and cleaned up automatically (e.g. async { schedule }). 200 destroyed and cleaned up automatically (e.g. async { schedule }).
201 - implement a JIT compiler for part of the thread switch code,
202 which gives a 50% speed improvement on threaded perls, and
203 about 4% on non-threaded perls (so threaded perls now finally
204 reach about half the speed of non-threaded perls).
205 - slightly modernise Coro::Intro, add section about rouse functions.
206 - avoid DEFSV and ERRSV, giving another 10% improvement
207 in thread switching.
