8TODO: testcancel
9TODO: guard as SLF - to avoid deadlocks.
10TODO: Coro::Signal as SLF.
11 - avoid deadlock in Coro::Channel if maxsize == 1 (Richard Hundt).
12
135.0
14 - NEW ARCHITECTURE: use the latest 4.x version if you experience
15 stability issues.
16 - bump API version to 7 - all dependents must be recompiled.
17 - removed timed_* functions - they were not being used anyways
18 and should be replaced by a more generic mechanism -
19 and were annoying to support anyways :)
20 - removed SemaphoreSet's waiter method - use sem instead.
21 - Coro::Semaphore->adjust didn't correctly wake up enough waiters.
22 - async_pool did free a scalar value twice
23 ("Attempt to unreference...").
24 - fix a longstanding bug where calling terminate on a coro that
25 was waiting for a semaphore that was just becoming available
26 would cause a deadlock (semaphore would get into a state where
27 it was available but waiters were waiting(.
28 - calling throw on a coroutine that is waiting for a semaphore will
29 no longer make it acquire the semaphore (and thus leak a count).
30 - perl's process emulation is now not even theoretically supported
31 anymore.
32 - use named constants in Coro::Channel (Richard Hundt).
33 - directly patch the entersub opcode calling SLF functions (cede,
34 transfer and so on). this does speed up context switching, but
35 more importanly, it frees us from the hardcoded behaviour of
36 entersub, so we might actually be able to return something from
37 those functions and atcually create new ones.
38 - take advantage of __builtin_frame_address on gcc.
39 - expose THX in coroapi (not sure whether this was a wise decision,
40 as "threaded" perls are running at half speed anyways).
41 - implement execute_slf (schedule-like-function) interface that makes
42 it possible to implement schedule-like-functions in XS.
43 - use new SLF interface to massively speed up Coro::EV by roughly a
44 factor of two.
45 - used new SLF interface to massively speed up Coro::Semaphore by a
46 factor of three.
47 - used new SLF interface to speed up Coro::AIO by roughly a factor of
48 four and reduce its memory usage considerably.
49 - implement Coro::SemaphoreSet purely in terms of Coro::Semaphore,
50 for a nice speedup and vastly more correct behaviour. Also implement
51 a new method "sem" to get at the underlying semaphore object.
52 - implement Coro::Channel in terms of Coro::Semaphore, for a moderate
53 (in comparison) 20-40% speedup.
54 - forgot to include Coro/libcoro/README in the dist for all these years.
55 - work around a freebsd pthreads bug (manual testcancel is required as
56 pthread_cond_wait isn't a cancellation point on freebsd).
57
584.913 Sat Nov 15 07:58:28 CET 2008
59 - async_pool did free a scalar value twice
60 ("Attempt to unreference...").
61
624.912 Thu Nov 13 18:31:23 CET 2008
63 - minor cleanups.
64 - use much larger stacks on linux and perl < 5.8.8.
65 - Coro::Debug::new_unix_server did not unlink the socket
66 when destroyed.
67
684.911 Tue Nov 11 04:26:17 CET 2008
69 - "port" to threaded perls.
70
714.91 Mon Nov 10 05:36:38 CET 2008
72 - the ->throw exception object no longer leaks.
73 - creating a new cctx leaked a scopestack entry (memleak).
74 - new coroutines didn't get created with a zero flags field
75 (unknown impact).
76 - calling ->throw on a not-yet-started coroutine should now work
77 instead of being ignored.
78 - ->throw is now supported on Coro::State objects.
79 - clean up cctx creation code a bit.
80 - entersub is actually a UNOP, not a LOGOP (not a bugfix).
81
824.9 Sat Nov 8 17:45:27 CET 2008
83 - (libcoro) did not preserve rbp with CORO_ASM (we are getting there).
84 - (libcoro) no longer leak threads in the experimental pthread backend,
85 also speed it up considerably.
86 - (libcoro) do not rely on makecontext passing void *'s unscathed.
87 - fix compiletime dependencies on libcoro in the Makefile.
88 - cctx_count wasn't always updated properly.
89 - Coro::State::cctx_stacksize wasn't applied correctly.
90 - new function Coro::State::cctx_max_idle.
91 - the default max number of idle C contexts is now 4.
92 - (libcoro) try harder to get _setjmp/_longjmp.
93 - (libcoro) cleanup and extend the libcoro API to officially
94 allow the creation of empty source contexts.
95 - very experimental workaround for the totally broken netbsd platform.
96 - tried to hack around openbsd bugs.
97
984.804 Wed Nov 5 16:36:00 CET 2008
99 - Coro::Debug::new_unix_server would not create a non-blocking listening
100 socket, sometimes causing freezes.
101 - (libcoro) fix misaligned stack points for setjmp and assembly
102 methods, which can cause crashes on x86/x86_64 with a sufficiently
103 aggressive compiler.
104 - new function: Coro::Debug::new_tcp_server.
105 - move ->throw into the Coro class because it only works on coro objects.
106
1074.803 Mon Nov 3 17:16:12 CET 2008
108 - (libcoro) use a global asm statement to become independent of gcc
109 otpimisations for CORO_ASM (thanks to pippijn for the idea).
110 - try to workaround yet another broken bsd, this time dragonfly.
111
1124.802 Thu Oct 30 10:56:12 CET 2008
113 - support -fno-omit-frame-pointer on x86 with the assembly method.
114 - tune 01_unblock.t tests a bit.
115
1164.801 Wed Oct 22 18:33:37 CEST 2008
117 - improve readline speed for very long "lines".
118 - backport to 5.8.8.
119
1204.8 Thu Oct 2 13:34:40 CEST 2008
121 - new function Coro::AIO::aio_wait.
122 - Coro.:AIO and Coro::BDB now "use Coro::AnyEvent".
123 - greatly speed up and reduce memory usage of Coro::AIO requests.
124 - implement some other ยต-optimisations.
125
1264.749 Mon Sep 29 14:40:12 CEST 2008
127 - port to slow and broken pseudo-threaded perls. (courtesy pippijn).
128
1294.748 Sat Sep 27 14:03:19 CEST 2008
130 - implement, but do not document, PerlIO::cede(granularity).
131 - Coro::Storable forgot to wrap Storable::pstore.
132 - work around the multitude of leaks and memory corruption
133 bugs in PerlIO::via by using our own C-level perliol. As a side
134 effect, Coro::Storable is now much, much, much faster.
135
1364.747 Tue Sep 23 01:59:41 CEST 2008
137 - fix a per-cv memleak (one empty array was leaked per
138 code reference).
139 - avoid a crash in coro->call|rss when the coroutine was already
140 destroyed (most noticably when using Coro::Debug::ps :)
141 - also protect *Storable::FILE.
142 - push up default storable granularity to 20ms.
143
1444.746 Sun Sep 21 03:22:20 CEST 2008
145 - be more insistent on locking Storable against reentrancy
146 in Coro::Storable.
147 - move swap_def?v and throw to Coro::State, as documented.
148
1494.745 Thu Jul 24 00:14:38 CEST 2008
150 - remove debugging code related to MgPV_nolen_const, also try to
151 make it compile with perl 5.8.6 (yes, apple apparently loves
152 outdated software). Reported by John S.
153
1544.744 Tue Jul 8 22:06:35 CEST 2008
155 - correctly provide default DIE/WARN handlers as documented.
156 - also overwrite PL_vtbl_sigelem.svt_clear, even though current
157 implementations inside perl work fine for us.
158
1594.743 Mon Jun 16 00:21:57 CEST 2008
160 - when using Coro::EV without running EV::loop it could
161 result in busy-waiting for events, this has been fixed.
162 - reduce codesize and improve performance by using EV_DEFAULT_UC.
163
1644.742 Sat May 31 14:10:21 CEST 2008
165 - implement a workaround for (some) perl <5.8.8 versions.
166 - require EV 3.3+.
167
1684.741 Fri May 30 23:33:09 CEST 2008
169 - tell netbsd how utterly broken their imitation of an OS is
170 and refuse to build by default if pthreads are in use.
171 - switch to "s" method on all bsd's by default, as their ucontext
172 stuff seems just too broken.
173 - fix a bug in Coro::Select.
174
1754.74 Thu May 29 20:05:31 CEST 2008
176 - do not test Coro::LWP for lack of dependencies.
177 - do not test Coro::Select for lack of working perls.
178
1794.73 Thu May 29 2008
180 - fix a bug in Coro::EV which would cause it to block despite
181 there being runnable coroutines.
182 - sprinkle "no warnings" freely over everything, also suppress
183 warnings for some other modules.
184 - fix typo in WSAEWOULDBLOCK.
185
1864.72 Sun May 25 05:14:36 CEST 2008
187 - tweak META.yaml a bit, unfortunately, there is no documented way
188 to have optional dependencies with CPAN. doh :(
189 - avoid running some tests on windows because they would fail due to
190 perl bug (broken fork, broken pipes...).
191 - work around perl on windows bugs where perl returns undocumented
192 error codes for sysread, syswrite etc. by taking advantage
193 of AnyEvent's workaround for that problem.
194 - use AnyEvent::Util::fh_nonblocking in Coro::Handle to work around
195 a common perl implementation bug on windows.
196 - use unix domain sockets in testsuite to work around
197 common perl implementation bugs on widows (they are emulated by
198 tcp sockets on windows. ugh.)
199
2004.71 Sat May 24 20:01:27 CEST 2008
201 - fix a bug in Coro::AnyEvent ("Usage: Coro::AnyEvent::_schedule()").
202 - take advantage of async name resolution of AnyEvent::Util.
203 - work around brutal inet_aton override in Coro::LWP.
204 - take advantage of the readyhook in Coro::EV, for smoother
205 scheduling.
206
2074.7 Sun May 11 00:32:19 CEST 2008
208 - completely reworked the Coro manpage.
209 - added Coro::AnyEvent, generic event loop integration.
210 - implement cancel, ready and kill commands in Coro::Debug.
211 - document find_coro in Coro::Debug.
212 - incompatible change: rename has_stack to has_cctx.
213 - Coro::AIO and Coro::BDB no longer force event model detection,
214 use AnyEvent::AIO and AnyEvent::BDB.
215
2164.6 Sat Apr 26 10:05:14 CEST 2008
217 - INCOMPATIBLE CHANGE: sub/code attributes are no longer supported
218 by the Coro module. It was a mistake to have it in the first place.
219 - (experimental) support for activestate perl 5.10 (method "w").
220 - (experimental) support for strawberry perl (method "a").
221 - coro_sigelem_set did not return a value although it had to,
222 actual impact unknown.
223
2244.51 Mon Apr 14 13:28:27 CEST 2008
225 - make it compile again on 5.8.
226
2274.50 Thu Apr 10 09:43:17 CEST 2008
228 - I did it twice! (see 4.49).
229
2304.49 Sun Apr 6 21:23:31 CEST 2008
231 - grr, instead of compiling the recent changes on 5.10 only they
232 were compiled on 5.8 only.
