8 - "port" to threaded perls.

104.91 Mon Nov 10 05:36:38 CET 2008
11 - the ->throw exception object no longer leaks.
12 - creating a new cctx leaked a scopestack entry (memleak).
13 - new coroutines didn't get created with a zero flags field
14 (unknown impact).
15 - calling ->throw on a not-yet-started coroutine should now work
16 instead of being ignored.
17 - ->throw is now supported on Coro::State objects.
18 - clean up cctx creation code a bit.
19 - entersub is actually a UNOP, not a LOGOP (not a bugfix).

214.9 Sat Nov 8 17:45:27 CET 2008
22 - (libcoro) did not preserve rbp with CORO_ASM (we are getting there).
23 - (libcoro) no longer leak threads in the experimental pthread backend,
24 also speed it up considerably.
25 - (libcoro) do not rely on makecontext passing void *'s unscathed.
26 - fix compiletime dependencies on libcoro in the Makefile.
27 - cctx_count wasn't always updated properly.
28 - Coro::State::cctx_stacksize wasn't applied correctly.
29 - new function Coro::State::cctx_max_idle.
30 - the default max number of idle C contexts is now 4.
31 - (libcoro) try harder to get _setjmp/_longjmp.
32 - (libcoro) cleanup and extend the libcoro API to officially
33 allow the creation of empty source contexts.
34 - very experimental workaround for the totally broken netbsd platform.
35 - tried to hack around openbsd bugs.
36
374.804 Wed Nov 5 16:36:00 CET 2008
38 - Coro::Debug::new_unix_server would not create a non-blocking listening
39 socket, sometimes causing freezes.
40 - (libcoro) fix misaligned stack points for setjmp and assembly
41 methods, which can cause crashes on x86/x86_64 with a sufficiently
42 aggressive compiler.
43 - new function: Coro::Debug::new_tcp_server.
44 - move ->throw into the Coro class because it only works on coro objects.
45
464.803 Mon Nov 3 17:16:12 CET 2008
47 - (libcoro) use a global asm statement to become independent of gcc
48 otpimisations for CORO_ASM (thanks to pippijn for the idea).
49 - try to workaround yet another broken bsd, this time dragonfly.
50
514.802 Thu Oct 30 10:56:12 CET 2008
52 - support -fno-omit-frame-pointer on x86 with the assembly method.
53 - tune 01_unblock.t tests a bit.
54
554.801 Wed Oct 22 18:33:37 CEST 2008
56 - improve readline speed for very long "lines".
57 - backport to 5.8.8.
58
594.8 Thu Oct 2 13:34:40 CEST 2008
60 - new function Coro::AIO::aio_wait.
61 - Coro.:AIO and Coro::BDB now "use Coro::AnyEvent".
62 - greatly speed up and reduce memory usage of Coro::AIO requests.
63 - implement some other ยต-optimisations.
64
654.749 Mon Sep 29 14:40:12 CEST 2008
66 - port to slow and broken pseudo-threaded perls. (courtesy pippijn).
67
684.748 Sat Sep 27 14:03:19 CEST 2008
69 - implement, but do not document, PerlIO::cede(granularity).
70 - Coro::Storable forgot to wrap Storable::pstore.
71 - work around the multitude of leaks and memory corruption
72 bugs in PerlIO::via by using our own C-level perliol. As a side
73 effect, Coro::Storable is now much, much, much faster.
74
754.747 Tue Sep 23 01:59:41 CEST 2008
76 - fix a per-cv memleak (one empty array was leaked per
77 code reference).
78 - avoid a crash in coro->call|rss when the coroutine was already
79 destroyed (most noticably when using Coro::Debug::ps :)
80 - also protect *Storable::FILE.
81 - push up default storable granularity to 20ms.
82
834.746 Sun Sep 21 03:22:20 CEST 2008
84 - be more insistent on locking Storable against reentrancy
85 in Coro::Storable.
86 - move swap_def?v and throw to Coro::State, as documented.
87
884.745 Thu Jul 24 00:14:38 CEST 2008
89 - remove debugging code related to MgPV_nolen_const, also try to
90 make it compile with perl 5.8.6 (yes, apple apparently loves
91 outdated software). Reported by John S.
92
934.744 Tue Jul 8 22:06:35 CEST 2008
94 - correctly provide default DIE/WARN handlers as documented.
95 - also overwrite PL_vtbl_sigelem.svt_clear, even though current
96 implementations inside perl work fine for us.
97
984.743 Mon Jun 16 00:21:57 CEST 2008
99 - when using Coro::EV without running EV::loop it could
100 result in busy-waiting for events, this has been fixed.
101 - reduce codesize and improve performance by using EV_DEFAULT_UC.
102
1034.742 Sat May 31 14:10:21 CEST 2008
104 - implement a workaround for (some) perl <5.8.8 versions.
105 - require EV 3.3+.
106
1074.741 Fri May 30 23:33:09 CEST 2008
108 - tell netbsd how utterly broken their imitation of an OS is
109 and refuse to build by default if pthreads are in use.
110 - switch to "s" method on all bsd's by default, as their ucontext
111 stuff seems just too broken.
112 - fix a bug in Coro::Select.
113
1144.74 Thu May 29 20:05:31 CEST 2008
115 - do not test Coro::LWP for lack of dependencies.
116 - do not test Coro::Select for lack of working perls.
117
1184.73 Thu May 29 2008
119 - fix a bug in Coro::EV which would cause it to block despite
120 there being runnable coroutines.
121 - sprinkle "no warnings" freely over everything, also suppress
122 warnings for some other modules.
123 - fix typo in WSAEWOULDBLOCK.
124
1254.72 Sun May 25 05:14:36 CEST 2008
126 - tweak META.yaml a bit, unfortunately, there is no documented way
127 to have optional dependencies with CPAN. doh :(
128 - avoid running some tests on windows because they would fail due to
129 perl bug (broken fork, broken pipes...).
130 - work around perl on windows bugs where perl returns undocumented
131 error codes for sysread, syswrite etc. by taking advantage
132 of AnyEvent's workaround for that problem.
133 - use AnyEvent::Util::fh_nonblocking in Coro::Handle to work around
134 a common perl implementation bug on windows.
135 - use unix domain sockets in testsuite to work around
136 common perl implementation bugs on widows (they are emulated by
137 tcp sockets on windows. ugh.)
138
1394.71 Sat May 24 20:01:27 CEST 2008
140 - fix a bug in Coro::AnyEvent ("Usage: Coro::AnyEvent::_schedule()").
141 - take advantage of async name resolution of AnyEvent::Util.
142 - work around brutal inet_aton override in Coro::LWP.
143 - take advantage of the readyhook in Coro::EV, for smoother
144 scheduling.
145
1464.7 Sun May 11 00:32:19 CEST 2008
147 - completely reworked the Coro manpage.
148 - added Coro::AnyEvent, generic event loop integration.
149 - implement cancel, ready and kill commands in Coro::Debug.
150 - document find_coro in Coro::Debug.
151 - incompatible change: rename has_stack to has_cctx.
152 - Coro::AIO and Coro::BDB no longer force event model detection,
153 use AnyEvent::AIO and AnyEvent::BDB.

84.6 Sat Apr 26 10:05:14 CEST 2008 1554.6 Sat Apr 26 10:05:14 CEST 2008
9 - INCOMPATIBLE CHANGE: sub/code attributes are no longer supported 156 - INCOMPATIBLE CHANGE: sub/code attributes are no longer supported
10 by the Coro module. It was a mistake to have it in the first place. 157 by the Coro module. It was a mistake to have it in the first place.
11 - (experimental) support for activestate perl 5.10 (method "w"). 158 - (experimental) support for activestate perl 5.10 (method "w").
