9 | - convert Coro::Timer, Coro::Select and Coro::Util to rouse API. |
| 10 | TODO: Coro::Semaphore |
10 | - Coro::Select did errornously dup the file descriptors |
| 11 | 5.0 |
11 | and didn't work with all AnyEvent backends. |
| 12 | - NEW ARCHITECTURE: use 4.912 for the stable version. |
12 | - disassociate c contexts from coro objects - this is agruably more |
|
|
13 | correct, but mostly allows sharing of cctxs between coro and state |
|
|
14 | objects, for added memory savings and speed increases. |
|
|
15 | - bumped $Coro::POOL_RSS up to 32kb by default. |
|
|
16 | - no longer set the optype to OP_CUSTOM, as B::* understandably |
|
|
17 | doesn't like this very much (and we *are* a type of entersub). |
|
|
18 | - implement state cloning, just to prove that call/cc can be done. |

32 | - fix a longstanding bug where calling terminate on a coro that |
|
|
33 | was waiting for a semaphore that was just becoming available |

|
|
35 | it was available but waiters were still blocked). |

60 | - used new SLF interface to speed up Coro::AIO by roughly a factor of |

61 | four and reduce its memory usage considerably. |
|
|
62 | - implement Coro::SemaphoreSet purely in terms of Coro::Semaphore, |
|
|
63 | for a nice speedup and vastly more correct behaviour. Also implement |
|
|
64 | a new method "sem" to get at the underlying semaphore object. |
|
|
65 | - implement Coro::Channel in terms of Coro::Semaphore, for a moderate |
|
|
66 | (in comparison) 20-40% speedup. |
|
|
67 | - used new SLF interface to reimplement Coro::Signal gaining |
|
|
68 | some unknown (because I was too lazy), but certain, speedup, and also |
|
|
69 | making signals reliable for the first time. |

70 | - used new SLF interface and other optimisations to speed up async_pool |
|
|
71 | by a factor of two. It also doesn't rely on perl's exception mechanism |
|
|
72 | to exit anymore. The overhead for terminating an async_pool, coro over |
|
|
73 | a normal async is now very small. |
