11
126.48 Sun Oct 4 19:03:51 CEST 2015
13 - fix memory leak when Coro::Handle uses Coro::EV internally
14 (testcase by Sten Sten).
15 - update code to libev 4 API (internally, Coro still used the
16 version 3 API calls).
17 - remove unused hv_sig.
18
196.47 Sat Jul 11 03:58:20 CEST 2015
20 - swap_svs - NVs can be in the SV head beginning with 5.20.
21
226.46 Tue Jun 30 14:36:30 CEST 2015
23 - restore portability to perls with windows fork emulation
24 (patch by Petr Písař).
25
266.45 Tue Jun 30 01:40:08 CEST 2015
27 - restore portability to perl 5.16 and below.
28
296.44 Tue Jun 30 00:41:54 CEST 2015
30 - avoid segfaulting (or worse) when tracing a canceled thread.
31 - the Event module silently broke it's public hook API, causing
32 failures on perls compiled with -Duselongdouble. Requiring
33 the latest version of Event because I don't know which release
34 changed this (it's not mentioned in the ChangeLog).
35 - allow xs level enterleave hooks via CoroAPI.
36
376.43 Thu Jun 4 15:38:14 CEST 2015
38 - use stability canary.
39 - port to stableperl-5.22.0-1.001.
40 - update libecb.
41
426.42 Wed Feb 11 20:29:52 CET 2015
43 - Coro::SemaphoreSet->try did not actually work (analyzed by
44 SATO Kentaro).
45 - upgrade libecb to be C11 compliant.
46
476.41 Sat Sep 6 22:08:46 CEST 2014
48 - restore portability to perl 5.8.x.
49 - give new Coro's a valid GvHV(PL_hintgv) - this is slow and takes
50 up some memory, but fixes "use feature" and similar modules
51 when used inside a Coro.
52 - allow zero as argument to Coro::Channel to mean the same thing
53 as no argument. this works with older versions as well,
54 but wasn't legal until now.
55 - slightly better c header file detection.
56
576.39 Mon Jun 2 00:00:08 CEST 2014
58 - work around more incompatible changes in 5.20.
59
606.38 Sun Jun 1 21:54:23 CEST 2014
61 - check that perl slots actually have enough space to hold
62 interpreter variables.
63 - untested port to perl 5.19 (64 bit tmps indices) (reported
64 by Andreas König).
65 - croak when cancel is called without a thread context.
66
676.37 Tue Mar 4 13:27:33 CET 2014
68 - *sigh*, removed leftover debugging code from debugging a
69 perl bug, of all things.
70
716.36 Tue Mar 4 07:11:59 CET 2014
72 - semaphores would not clear the destroy hook when interrupted
73 by ->throw, causing segfaults or worse.
74 - ->throw on a thread waiting for a semaphore did not acquire
75 the semaphore, but also didn't wake up other waiters,
76 possibly causing a deadlock.
77 - "FATAL: $Coro::IDLE blocked itself" will now use Carp::confess
78 to report a full stacktrace, which should help find out
79 where the actual call is.
80 - "atomically" destroy data in slf_destroy, because it is
81 the right thing to do, just in case.
82 - disable ecb.h libm dependency, to compile on ancient systems
83 or under adverse conditions.
84
856.33 Mon Nov 18 11:26:27 CET 2013
86 - do not crash when freeing padlists with holes (in 5.18).
87 - tentative SVt_BIND 5.19 port/fix.
88
896.32 Tue Nov 5 15:35:35 CET 2013
90 - use a new algorithm to derive padlists for perl 5.18. The old
91 one could lead to 0-pointer accesses inside perl (reported
92 by Darin McBride).
93
946.31 Thu May 9 07:39:48 CEST 2013
95 - Coro::AIO requests would crash if the thread was ready'd
96 while the request was ongoing.
97
986.29 Wed May 8 02:55:18 CEST 2013
99 - when an on_destroy handler destructs the coro currently being
100 destructed a perl scalar could be accessed after being freed,
101 likely causing a crash.
102
1036.28 Wed Mar 6 06:58:02 CET 2013
104 - clean remnants of existing __DIE__ and __WARN__ handlers so
105 they lose their magic and will not cause segfaults later
106 (testcase by Andrey Sagulin).
107 - improved Coro::State documentation a bit.
108 - Coro::Debug::command now flushes the output.
109 - add hack detection code for x32 abi, because the braindead slugs
110 who designed that made it look exactly like x86_64 without
111 providing proper compile time symbols to test for it. as a result,
112 this detection cannot work reliably.
113 - valgrind stack registering was broken.
114 - do not rely on Time::HiRes anymore in Coro::Debug.
115
1166.23 Fri Dec 7 23:36:37 CET 2012
117 - use experimental fiber implementation on native windows
118 perls.
119 - use sizeof (void *) as multiplication factor for stack sizes,
120 to accomodate the totally braindamaged microsoft 64 bit "os".
121 - changed verifier host from win2k-ap510-32 to win7-sp516-32/64.
122 activeperl 5.16 crashes when PerlIO_define_layer is called due
123 to some bug in the perl dll, strawberry perl at least passes
124 the testsuite.
125 - implement Coro::Handle->peeraddr/host/port, for slightly
126 improved compatibility with LWP.
127 - implement 5.17 compatibility by almost blindly applying a
128 good-looking patch by Father Chrysostomos.
129 - move stack management functions into libcoro 3.
130 - libcoro version 3 "released".
131 - support magic values as timed_io_once args.
132 - recommend AnyEvent 7+ or EV 4+, also require EV
133 version 4 or newer for Coro::EV.
134
1356.10 Tue Oct 9 01:14:27 CEST 2012
136 - updated ecb.h, it had a typo that caused it to not compile on many
137 big endian systems (reported by many people).
138 - disable memory fences in ecb.h to improve portability.
139
1406.09 Sat Oct 6 23:25:02 CEST 2012
141 - Coro::EV I/O watchers were not interruptible by exceptions
142 (Coro::State::throw) (testcase by sten).
143 - ->throw now puts threads into the ready queue, as this seems to
144 be expected by existing code, and code that doesn't cope with spurious
145 wakeups needs fixing anyway.
146 - use fd -1 in mmap.
147 - cast I32 to int in error message printf.
148 - warn about broken so-called "hardened" kernels.
149
1506.08 Fri Apr 13 12:05:47 CEST 2012
151 - be more aggressive about exiting like perl does - formerly,
152 exiting from the non-main thread would not execute END blocks.
153
1546.07 Fri Nov 11 21:21:48 CET 2011
155 - work around a bug in PerlIO (setting $SIG{__WARN__} to a PVCV).
156 - update ecb.h.
157
1586.06 Mon Aug 8 23:59:48 CEST 2011
159 - cygwin unfortunately patches the stack at runtime, so we use the pthreads
160 backend, which is an order of magnitude slower. unfortunately, cygwins
161 pthread implementation isn't very complete either, so allocate the stack
162 twice just to be sure.
163 (note: cygwin also enables mymalloc, which is NOT THREADSAFE ON WINDOWS,
164 in its ithreaded perl - best recompile cygwin and use the 'w'indows
165 backend for much better performance. also disable ithreads for
166 even better performance...).
167
1686.05 Thu Aug 4 21:36:36 CEST 2011
169 - blush, condvar values would not be propagated from send to recv anymore
170 (reported by Chip Salzenberg).
171 - use exponential increase for the readline buffer length in
172 Coro::Handle. also reduce initial allocation to 1020 from 4096 bytes.
173
1746.04 Wed Aug 3 17:15:45 CEST 2011
175 - use even more efficient and more compatible condvars for
176 compatibility to AnyEvent 6.x :)
177 - more inconsequential ecb.h updates.
178
1796.03 Wed Aug 3 11:41:30 CEST 2011
180 - change how Coro patches AnyEvent condvars for compatibility to
181 AnyEvent 6.x.
182 - update ecb.h, to no longer include <pthread.h> in case WinNT.h
183 hasn't been included.
184
1856.02 Wed Jul 13 04:35:19 CEST 2011
186 - "improve portability to Gentoo" - gentoo manages to put perl variables
187 in memory areas that are farther than 2gb apart, which the jit couldn't
188 handle and barfed. now it's just a bit slower on gentoo and similar
189 systems.
190
1916.01 Sun Jul 3 12:31:14 CEST 2011
192 - workarounds are good, but the test for whether pthreads are used
193 was not good. this one should be better.
194 - check differently whether gcc generates cfi instructions itself.
195
1966.0 Wed Jun 29 19:43:35 CEST 2011
8 - INCOMPATIBLE CHANGE: unreferenced coro objects will now be 197 - INCOMPATIBLE CHANGE: unreferenced coro objects will now be
9 destroyed and cleaned up automatically (e.g. async { schedule }). 198 destroyed and cleaned up automatically (e.g. async { schedule }).
199 - implement a JIT compiler for part of the thread switch code,
200 which gives a 50% speed improvement on threaded perls, and
201 about 4% on non-threaded perls (so threaded perls now finally
202 reach about half the speed of non-threaded perls).
203 - slightly modernise Coro::Intro, add section about rouse functions.
204 - avoid DEFSV and ERRSV, giving another 10% improvement
205 in thread switching.
10 - Coro::State->is_destroyed is now called is_zombie. 206 - Coro::State->is_destroyed is now called is_zombie.
207 - implement a Coro->safe_cancel method that might fail, but
208 cancels in a "safer" way if it succeeds.
209 - add preliminary support for DEBUGGING perls.
210 - get rid of two hash-accesses when initialising a new Coro - this
211 speeds up coro creation by almost a factor of two.

231 - simplify warn/die hook handling when loading Coro - the convoluted
232 logic seems to be no longer neccessary.
233 - use libecb instead of our own home-grown gcc hacks.
234 - document alternatives to Coro::LWP. Please use them :)
235 - work around another mindless idiotic NEEDLESS bug in openbsd/mirbsds
236 sigaltstack. Really. wine suffers from it, erlang suffers from it,
237 and it's known since at least 2006.
