18 | - don't set diehook to C<undef> but instead to NULL, to avoid |

|
|
20 | - take advantage of the new Guard module. |

23 | 5.12 Sun Dec 7 13:30:38 CET 2008 |
|
|
24 | - add default config for MirOS, which seems to be a bug-to-bug |
|
|
25 | compatible fork of openbsd ("world domination by releasing |
|
|
26 | openbsd cvs before the openbsd folks do it" or so :). |
|
|
27 | - free_padlist did destroy the names pad, not good, but didn't |
|
|
28 | seem to bother perl - this could fix issues such as eval "" |
|
|
29 | inside a function called from multiple coroutines. |
|
|
30 | - use a different method to detect destruction time. |
|
|
31 | - be more careful when freeing padlists just before global |
|
|
32 | destruction. |
|
|
33 | - fixed and expanded the call/cc example. |
|
|
34 | - renamed _terminate to _coro_run. |
|
|

|
|
36 | - try pthreads on openbsd <4.4 (broken sigaltstack, will |

37 | pthreads fare better?). |
|

40 | 5.11 Tue Nov 25 21:49:05 CET 2008 |
|
|
41 | - DEBUGGING in 5.10.0 is a mess: it constantly flags perfectly |

42 | working code with failed assertions, introducing more bugs than |

|
45 | 5.1 Mon Nov 24 08:54:59 CET 2008 |
|
|
46 | - wrote a small introductory tutorial - Coro::Intro. |
|
|
47 | - convert Coro::Timer, Coro::Select and Coro::Util to rouse API. |
|
|
48 | - Coro::Select did errornously dup the file descriptors |
|
|
49 | and didn't work with all AnyEvent backends. |
|
|
50 | - Coro::Select wasn't imported correctly form Coro::LWP, causing blocking |
|
|
51 | LWP data transfers. |
|
|
52 | - disassociate c contexts from coro objects - this is agruably more |
|
|
53 | correct, but mostly allows sharing of cctxs between coro and state |
|
|
54 | objects, for added memory savings and speed increases. |
|
|
55 | - bumped $Coro::POOL_RSS up to 32kb by default. |
|
|
56 | - no longer set the optype to OP_CUSTOM, as B::* understandably |
|
|
57 | doesn't like this very much (and we *are* a type of entersub). |
|
|
58 | - implement state cloning, just to prove that call/cc can be done. |
|
|
59 | - automatically load Coro::AnyEvent in Coro::Handle. |
|
|
60 | - wrap ->cancel calls in eval inside Coro::Handle as EV watchers |
|
|
61 | do not have this method (and don't need it either). |
|
|
62 | - speed up generic anyevent methods in Coro::Handle by using rouse |
|
|
63 | callbacks. |
|
|
64 | - allow coroutines in $Coro::IDLE, speeding up Coro::AnyEvent and |
|
|
65 | others. It also makes the debugger happier, as you can trace |
|
|
66 | through the idle threads now. |
|
|
67 | - add comppad_name* and hints ($^H, %^H) to per-thread variables. |
|
|
68 | - eg/event was pretty broken. |
|
|
69 | - better 5.8.6 compatibility. |
|
|

71 | 5.0 Thu Nov 20 10:35:05 CET 2008 |
|
|
72 | - NEW ARCHITECTURE: use the latest 4.x version if you experience |
|

73 | stability issues. |

76 | and should be replaced by a more generic mechanism - |
|
|
77 | and were annoying to support anyways :) |
|
|
78 | - removed SemaphoreSet's waiter method - use sem method instead. |
| 16 | - Coro::Semaphore->adjust didn't correctly wake up enough waiters. |

85 | it was available but waiters were still blocked). |
| 23 | - avoid deadlock in Coro::Channel if maxsize == 1 (Richard Hundt). |
86 | - calling throw on a coroutine that is waiting for a semaphore will |
|
|
87 | no longer make it acquire the semaphore (and thus leak a count). |

88 | - perl's process emulation is now not even theoretically supported |

89 | anymore. |
|
|
90 | - new functions Coro::rouse_cb and Coro::rouse_wait for easier |
|
|
91 | conversion of callback-style to blocking-style. |
|
|
92 | - new methods $coro->schedule_to and ->cede_to, to specifically |
|
|
93 | schedule or cede to a specific coroutine. |
|
|
94 | - new function Coro::Semaphore::wait. |
|
|
95 | - use named constants in Coro::Channel (Richard Hundt). |

109 | factor of three. |
|
|
110 | - used new SLF interface to speed up Coro::AIO by roughly a factor of |
|
|
111 | four and reduce its memory usage considerably. |
|
|
112 | - implement Coro::SemaphoreSet purely in terms of Coro::Semaphore, |
|
|
113 | for a nice speedup and vastly more correct behaviour. Also implement |
|
|
114 | a new method "sem" to get at the underlying semaphore object. |
|
|
115 | - implement Coro::Channel in terms of Coro::Semaphore, for a moderate |
|
|
116 | (in comparison) 20-40% speedup. |
|
|
117 | - used new SLF interface to reimplement Coro::Signal gaining |
|
|
118 | some unknown (because I was too lazy), but certain, speedup, and also |
|
|
119 | making signals reliable for the first time. |
|
|
120 | - used new SLF interface and other optimisations to speed up async_pool |
|
|
121 | by a factor of two. It also doesn't rely on perl's exception mechanism |
|
|
122 | to exit anymore. The overhead for terminating an async_pool, coro over |
|
|
123 | a normal async is now very small. |
|
|
124 | - sped up coroutine creation/destruction by 40%. |
| 43 | - forgot to include Coro/libcoro/README in the dist for all these years. |

|
|
128 | - use new rouse functions to speed up and simplify Coro::BDB. |
|
|
129 | - make "prefer perl native functions" work with threaded perls. |
|
|
130 | - condense Coro::Debug ps output, hint at v and w flags. |
|
|
131 | - (libcoro) lots of minor cleanups and portability improvements. |
