85.0
9 - NEW ARCHITECTURE: use 4.912 for the stable version.
10 - directly patch the entersub opcode calling ssl functions (cede,
11 transfer and so on). this does speed up context switching by
12 up to 10%. More importanly, it frees us from the hardcoded
13 behaviour of entersub, so we might actually be able to return
14 something from those functions.
15 - take advanatge of __builtin_frame_address on gcc.
16
174.912 Thu Nov 13 18:31:23 CET 2008
18 - minor cleanups.
19 - use much larger stacks on linux and perl < 5.8.8.
20 - Coro::Debug::new_unix_server did not unlink the socket
21 when destroyed.
22
234.911 Tue Nov 11 04:26:17 CET 2008
24 - "port" to threaded perls.
25
264.91 Mon Nov 10 05:36:38 CET 2008
27 - the ->throw exception object no longer leaks.
28 - creating a new cctx leaked a scopestack entry (memleak).
29 - new coroutines didn't get created with a zero flags field
30 (unknown impact).
31 - calling ->throw on a not-yet-started coroutine should now work
32 instead of being ignored.
33 - ->throw is now supported on Coro::State objects.
34 - clean up cctx creation code a bit.
35 - entersub is actually a UNOP, not a LOGOP (not a bugfix).
36
374.9 Sat Nov 8 17:45:27 CET 2008
38 - (libcoro) did not preserve rbp with CORO_ASM (we are getting there).
39 - (libcoro) no longer leak threads in the experimental pthread backend,
40 also speed it up considerably.
41 - (libcoro) do not rely on makecontext passing void *'s unscathed.
42 - fix compiletime dependencies on libcoro in the Makefile.
43 - cctx_count wasn't always updated properly.
44 - Coro::State::cctx_stacksize wasn't applied correctly.
45 - new function Coro::State::cctx_max_idle.
46 - the default max number of idle C contexts is now 4.
47 - (libcoro) try harder to get _setjmp/_longjmp.
48 - (libcoro) cleanup and extend the libcoro API to officially
49 allow the creation of empty source contexts.
50 - very experimental workaround for the totally broken netbsd platform.
51 - tried to hack around openbsd bugs.
52
534.804 Wed Nov 5 16:36:00 CET 2008
54 - Coro::Debug::new_unix_server would not create a non-blocking listening
55 socket, sometimes causing freezes.
56 - (libcoro) fix misaligned stack points for setjmp and assembly
57 methods, which can cause crashes on x86/x86_64 with a sufficiently
58 aggressive compiler.
59 - new function: Coro::Debug::new_tcp_server.
60 - move ->throw into the Coro class because it only works on coro objects.
61
624.803 Mon Nov 3 17:16:12 CET 2008
63 - (libcoro) use a global asm statement to become independent of gcc
64 otpimisations for CORO_ASM (thanks to pippijn for the idea).
65 - try to workaround yet another broken bsd, this time dragonfly.
66
674.802 Thu Oct 30 10:56:12 CET 2008
68 - support -fno-omit-frame-pointer on x86 with the assembly method.
69 - tune 01_unblock.t tests a bit.
70
714.801 Wed Oct 22 18:33:37 CEST 2008
72 - improve readline speed for very long "lines".
73 - backport to 5.8.8.
74
754.8 Thu Oct 2 13:34:40 CEST 2008
76 - new function Coro::AIO::aio_wait.
77 - Coro.:AIO and Coro::BDB now "use Coro::AnyEvent".
78 - greatly speed up and reduce memory usage of Coro::AIO requests.
79 - implement some other ยต-optimisations.
80
814.749 Mon Sep 29 14:40:12 CEST 2008
82 - port to slow and broken pseudo-threaded perls. (courtesy pippijn).
83
844.748 Sat Sep 27 14:03:19 CEST 2008
85 - implement, but do not document, PerlIO::cede(granularity).
86 - Coro::Storable forgot to wrap Storable::pstore.
87 - work around the multitude of leaks and memory corruption
88 bugs in PerlIO::via by using our own C-level perliol. As a side
89 effect, Coro::Storable is now much, much, much faster.
90
914.747 Tue Sep 23 01:59:41 CEST 2008
92 - fix a per-cv memleak (one empty array was leaked per
93 code reference).
94 - avoid a crash in coro->call|rss when the coroutine was already
95 destroyed (most noticably when using Coro::Debug::ps :)
96 - also protect *Storable::FILE.
97 - push up default storable granularity to 20ms.
98
994.746 Sun Sep 21 03:22:20 CEST 2008
100 - be more insistent on locking Storable against reentrancy
101 in Coro::Storable.
102 - move swap_def?v and throw to Coro::State, as documented.
103
1044.745 Thu Jul 24 00:14:38 CEST 2008
105 - remove debugging code related to MgPV_nolen_const, also try to
106 make it compile with perl 5.8.6 (yes, apple apparently loves
107 outdated software). Reported by John S.

9 - correctly provide default DIE/WARN handlers as documented. 110 - correctly provide default DIE/WARN handlers as documented.
10 - also overwrite PL_vtbl_sigelem.svt_clear, even though current 111 - also overwrite PL_vtbl_sigelem.svt_clear, even though current
11 implementations inside perl work fine for us. 112 implementations inside perl work fine for us.
