106.48 Sun Oct 4 19:03:51 CEST 2015
11 - fix memory leak when Coro::Handle uses Coro::EV internally
12 (testcase by Sten Sten).
13 - update code to libev 4 API (internally, Coro still used the
14 version 3 API calls).
15 - remove unused hv_sig.
16
176.47 Sat Jul 11 03:58:20 CEST 2015
18 - swap_svs - NVs can be in the SV head beginning with 5.20.
19
206.46 Tue Jun 30 14:36:30 CEST 2015
21 - restore portability to perls with windows fork emulation
22 (patch by Petr Písař).
23
246.45 Tue Jun 30 01:40:08 CEST 2015
25 - restore portability to perl 5.16 and below.
26
276.44 Tue Jun 30 00:41:54 CEST 2015
28 - avoid segfaulting (or worse) when tracing a canceled thread.
29 - the Event module silently broke it's public hook API, causing
30 failures on perls compiled with -Duselongdouble. Requiring
31 the latest version of Event because I don't know which release
32 changed this (it's not mentioned in the ChangeLog).
33 - allow xs level enterleave hooks via CoroAPI.
34
356.43 Thu Jun 4 15:38:14 CEST 2015
36 - use stability canary.
37 - port to stableperl-5.22.0-1.001.
38 - update libecb.
39
406.42 Wed Feb 11 20:29:52 CET 2015
41 - Coro::SemaphoreSet->try did not actually work (analyzed by
42 SATO Kentaro).
43 - upgrade libecb to be C11 compliant.
44
456.41 Sat Sep 6 22:08:46 CEST 2014
46 - restore portability to perl 5.8.x.
47 - give new Coro's a valid GvHV(PL_hintgv) - this is slow and takes
48 up some memory, but fixes "use feature" and similar modules
49 when used inside a Coro.
50 - allow zero as argument to Coro::Channel to mean the same thing
51 as no argument. this works with older versions as well,
52 but wasn't legal until now.
53 - slightly better c header file detection.
54
556.39 Mon Jun 2 00:00:08 CEST 2014
56 - work around more incompatible changes in 5.20.
57
586.38 Sun Jun 1 21:54:23 CEST 2014
59 - check that perl slots actually have enough space to hold
60 interpreter variables.
61 - untested port to perl 5.19 (64 bit tmps indices) (reported
62 by Andreas König).
63 - croak when cancel is called without a thread context.
64
656.37 Tue Mar 4 13:27:33 CET 2014
66 - *sigh*, removed leftover debugging code from debugging a
67 perl bug, of all things.
68
696.36 Tue Mar 4 07:11:59 CET 2014
70 - semaphores would not clear the destroy hook when interrupted
71 by ->throw, causing segfaults or worse.
72 - ->throw on a thread waiting for a semaphore did not acquire
73 the semaphore, but also didn't wake up other waiters,
74 possibly causing a deadlock.
75 - "FATAL: $Coro::IDLE blocked itself" will now use Carp::confess
76 to report a full stacktrace, which should help find out
77 where the actual call is.
78 - "atomically" destroy data in slf_destroy, because it is
79 the right thing to do, just in case.
80 - disable ecb.h libm dependency, to compile on ancient systems
81 or under adverse conditions.
82
836.33 Mon Nov 18 11:26:27 CET 2013
84 - do not crash when freeing padlists with holes (in 5.18).
85 - tentative SVt_BIND 5.19 port/fix.
86
876.32 Tue Nov 5 15:35:35 CET 2013
88 - use a new algorithm to derive padlists for perl 5.18. The old
89 one could lead to 0-pointer accesses inside perl (reported
90 by Darin McBride).
91
926.31 Thu May 9 07:39:48 CEST 2013
93 - Coro::AIO requests would crash if the thread was ready'd
94 while the request was ongoing.
95
966.29 Wed May 8 02:55:18 CEST 2013
97 - when an on_destroy handler destructs the coro currently being
98 destructed a perl scalar could be accessed after being freed,
99 likely causing a crash.
100
1016.28 Wed Mar 6 06:58:02 CET 2013
102 - clean remnants of existing __DIE__ and __WARN__ handlers so
103 they lose their magic and will not cause segfaults later
104 (testcase by Andrey Sagulin).
105 - improved Coro::State documentation a bit.
106 - Coro::Debug::command now flushes the output.
107 - add hack detection code for x32 abi, because the braindead slugs
108 who designed that made it look exactly like x86_64 without
109 providing proper compile time symbols to test for it. as a result,
110 this detection cannot work reliably.
111 - valgrind stack registering was broken.
112 - do not rely on Time::HiRes anymore in Coro::Debug.
113
1146.23 Fri Dec 7 23:36:37 CET 2012
115 - use experimental fiber implementation on native windows
116 perls.
117 - use sizeof (void *) as multiplication factor for stack sizes,
118 to accomodate the totally braindamaged microsoft 64 bit "os".
119 - changed verifier host from win2k-ap510-32 to win7-sp516-32/64.
120 activeperl 5.16 crashes when PerlIO_define_layer is called due
121 to some bug in the perl dll, strawberry perl at least passes
122 the testsuite.
123 - implement Coro::Handle->peeraddr/host/port, for slightly
124 improved compatibility with LWP.
125 - implement 5.17 compatibility by almost blindly applying a
126 good-looking patch by Father Chrysostomos.
127 - move stack management functions into libcoro 3.
128 - libcoro version 3 "released".
129 - support magic values as timed_io_once args.
130 - recommend AnyEvent 7+ or EV 4+, also require EV
131 version 4 or newer for Coro::EV.
132
1336.10 Tue Oct 9 01:14:27 CEST 2012
134 - updated ecb.h, it had a typo that caused it to not compile on many
135 big endian systems (reported by many people).
136 - disable memory fences in ecb.h to improve portability.
137
1386.09 Sat Oct 6 23:25:02 CEST 2012
139 - Coro::EV I/O watchers were not interruptible by exceptions
140 (Coro::State::throw) (testcase by sten).
141 - ->throw now puts threads into the ready queue, as this seems to
142 be expected by existing code, and code that doesn't cope with spurious
143 wakeups needs fixing anyway.
144 - use fd -1 in mmap.
145 - cast I32 to int in error message printf.
146 - warn about broken so-called "hardened" kernels.
147
1486.08 Fri Apr 13 12:05:47 CEST 2012
149 - be more aggressive about exiting like perl does - formerly,
150 exiting from the non-main thread would not execute END blocks.
151
1526.07 Fri Nov 11 21:21:48 CET 2011
153 - work around a bug in PerlIO (setting $SIG{__WARN__} to a PVCV).
154 - update ecb.h.
155
1566.06 Mon Aug 8 23:59:48 CEST 2011
157 - cygwin unfortunately patches the stack at runtime, so we use the pthreads
158 backend, which is an order of magnitude slower. unfortunately, cygwins
159 pthread implementation isn't very complete either, so allocate the stack
160 twice just to be sure.
161 (note: cygwin also enables mymalloc, which is NOT THREADSAFE ON WINDOWS,
162 in its ithreaded perl - best recompile cygwin and use the 'w'indows
163 backend for much better performance. also disable ithreads for
164 even better performance...).
165
1666.05 Thu Aug 4 21:36:36 CEST 2011
167 - blush, condvar values would not be propagated from send to recv anymore
168 (reported by Chip Salzenberg).
169 - use exponential increase for the readline buffer length in
170 Coro::Handle. also reduce initial allocation to 1020 from 4096 bytes.
171
1726.04 Wed Aug 3 17:15:45 CEST 2011
173 - use even more efficient and more compatible condvars for
174 compatibility to AnyEvent 6.x :)
175 - more inconsequential ecb.h updates.
176
1776.03 Wed Aug 3 11:41:30 CEST 2011
178 - change how Coro patches AnyEvent condvars for compatibility to
179 AnyEvent 6.x.
180 - update ecb.h, to no longer include <pthread.h> in case WinNT.h
181 hasn't been included.
182
1836.02 Wed Jul 13 04:35:19 CEST 2011
184 - "improve portability to Gentoo" - gentoo manages to put perl variables
185 in memory areas that are farther than 2gb apart, which the jit couldn't
186 handle and barfed. now it's just a bit slower on gentoo and similar
187 systems.
188
1896.01 Sun Jul 3 12:31:14 CEST 2011
190 - workarounds are good, but the test for whether pthreads are used
191 was not good. this one should be better.
192 - check differently whether gcc generates cfi instructions itself.
193
1946.0 Wed Jun 29 19:43:35 CEST 2011
195 - INCOMPATIBLE CHANGE: unreferenced coro objects will now be
196 destroyed and cleaned up automatically (e.g. async { schedule }).
197 - implement a JIT compiler for part of the thread switch code,
198 which gives a 50% speed improvement on threaded perls, and
199 about 4% on non-threaded perls (so threaded perls now finally
200 reach about half the speed of non-threaded perls).
201 - slightly modernise Coro::Intro, add section about rouse functions.
202 - avoid DEFSV and ERRSV, giving another 10% improvement
203 in thread switching.
204 - Coro::State->is_destroyed is now called is_zombie.
205 - implement a Coro->safe_cancel method that might fail, but
206 cancels in a "safer" way if it succeeds.
207 - add preliminary support for DEBUGGING perls.
208 - get rid of two hash-accesses when initialising a new Coro - this
209 speeds up coro creation by almost a factor of two.
7 - croak when a coro being cancelled tries to block (e.g. while executing 210 - croak when a coro that is being cancelled tries to block
8 a guard block). 211 (e.g. while executing a guard block), instead of crashing or
212 deadlocking.
213 - use a more robust and also faster method to identify Coro::State
214 objects - speeds up everything a bit.
9 - implement Coro->cancel in XS for a 20% speed improvement, and to 215 - implement Coro->cancel in XS for a 20% speed improvement, and to
10 be able to implement mutual cancellation. 216 be able to implement mutual cancellation.
217 - speed up context switches by a percent or two by more efficiently
218 allocating context stack entries.
219 - implement Coro->join and Coro->on_destroy in XS for a speedup and
220 a reduction in memory use.
11 - cancelling a coro while it itself is cancelling another coro is 221 - cancelling a coro while it itself is cancelling another coro is
12 now supported and working, instead of triggering an assertion. 222 now supported and working, instead of triggering an assertion.
13 - be a bit more crash-resistant when calling (buggy) on_destroy 223 - be a bit more crash-resistant when calling (buggy) on_destroy
14 callbacks (best effort). 224 callbacks (best effort).
225 - move on_destroy into the slf_frame, to allow extension slf
226 functions to have destructors.
227 - get rid if coro refcounting - simply crash in other interpreter
228 threads by nulling the pointers on clone.
229 - simplify warn/die hook handling when loading Coro - the convoluted
230 logic seems to be no longer neccessary.
231 - use libecb instead of our own home-grown gcc hacks.
232 - document alternatives to Coro::LWP. Please use them :)
233 - work around another mindless idiotic NEEDLESS bug in openbsd/mirbsds
234 sigaltstack. Really. wine suffers from it, erlang suffers from it,
235 and it's known since at least 2006.
