14 | 5.0 |
|
|
15 | - NEW ARCHITECTURE: use the latest 4.x version if you experience |
|
|
16 | stability issues. |
|
|
17 | - bump API version to 7 - all dependents must be recompiled. |
|
|
18 | - Coro::Semaphore->adjust didn't correctly wake up enough waiters. |
|
|
19 | - async_pool did free a scalar value twice |
|
|
20 | ("Attempt to unreference..."). |
|
|
21 | - fix a longstanding bug where calling terminate on a coro that |
|
|
22 | was waiting for a semaphore that was just becoming available |
|
|
23 | would cause a deadlock (semaphore would get into a state where |
|
|
24 | it was available but waiters were waiting(. |
|
|
25 | - avoid deadlock in Coro::Channel if maxsize == 1 (Richard Hundt). |
|
|
26 | - perl's process emulation is now not even theoretically supported |
|
|
27 | anymore. |
|
|
28 | - directly patch the entersub opcode calling SLF functions (cede, |
|
|
29 | transfer and so on). this does speed up context switching, but |
|
|
30 | more importanly, it frees us from the hardcoded behaviour of |
|
|
31 | entersub, so we might actually be able to return something from |
|
|
32 | those functions and atcually create new ones. |
|
|
33 | - take advantage of __builtin_frame_address on gcc. |
|
|
34 | - expose THX in coroapi (not sure whether this was a wise decision, |
|
|
35 | as "threaded" perls are running at half speed anyways). |
|
|
36 | - implement execute_slf (schedule-like-function) interface that makes |
|
|
37 | it possible to implement schedule-like-functions in XS. |
|
|
38 | - use new SLF interface to massively speed up Coro::EV by roughly a |
|
|
39 | factor of two. |
|
|
40 | - removed timed_down and timed_guard functions - they were not being |
|
|
41 | used anyways and should be replaced by a more generic mechanism - |
|
|
42 | and were annoying to support anyways :) |
|
|
43 | - used new SLF interface to massively speed up Coro::Semaphore by a |
|
|
44 | factor of three. |
|
|
45 | - used new SLF interface to speed up Coro::AIO by roughly a factor of |
|
|
46 | four and reduce its memory usage considerably. |
|
|
47 | - forgot to include Coro/libcoro/README in the dist for all these years. |
|
|
48 | - work around a freebsd pthreads bug (manual testcancel is required as |
|
|
49 | pthread_cond_wait isn't a cancellation point on freebsd). |
|
|
50 | |

55 | 4.912 Thu Nov 13 18:31:23 CET 2008 |
|
|
56 | - minor cleanups. |
|
|
57 | - use much larger stacks on linux and perl < 5.8.8. |
|
|
58 | - Coro::Debug::new_unix_server did not unlink the socket |
|
|
59 | when destroyed. |
|
|
60 | |
|
|
61 | 4.911 Tue Nov 11 04:26:17 CET 2008 |

62 | - "port" to threaded perls. |
|
|
63 | |
|
|
64 | 4.91 Mon Nov 10 05:36:38 CET 2008 |
|
|
65 | - the ->throw exception object no longer leaks. |
|
|
66 | - creating a new cctx leaked a scopestack entry (memleak). |
|
|
67 | - new coroutines didn't get created with a zero flags field |
|
|
68 | (unknown impact). |
|
|
69 | - calling ->throw on a not-yet-started coroutine should now work |
|
|
70 | instead of being ignored. |
|
|
71 | - ->throw is now supported on Coro::State objects. |
|
|
72 | - clean up cctx creation code a bit. |
|
|
73 | - entersub is actually a UNOP, not a LOGOP (not a bugfix). |
|
|
74 | |
|
|

|
|
79 | - (libcoro) do not rely on makecontext passing void *'s unscathed. |
|
|
80 | - fix compiletime dependencies on libcoro in the Makefile. |
|
|
81 | - cctx_count wasn't always updated properly. |
|
|
82 | - Coro::State::cctx_stacksize wasn't applied correctly. |
|
|
83 | - new function Coro::State::cctx_max_idle. |
|
|
84 | - the default max number of idle C contexts is now 4. |
|
|
85 | - (libcoro) try harder to get _setjmp/_longjmp. |
|
|
86 | - (libcoro) cleanup and extend the libcoro API to officially |
|
|
87 | allow the creation of empty source contexts. |
|
|
88 | - very experimental workaround for the totally broken netbsd platform. |
|
|
89 | - tried to hack around openbsd bugs. |
