|
|
21 | - wrote a small introductory tutorial - Coro::Intro. |
|
|
22 | - convert Coro::Timer, Coro::Select and Coro::Util to rouse API. |
|
|
23 | - Coro::Select did errornously dup the file descriptors |
|
|
24 | and didn't work with all AnyEvent backends. |
|
|
25 | - Coro::Select wasn't imported correctly form Coro::LWP, causing blocking |
|
|
26 | LWP data transfers. |
|
|
27 | - disassociate c contexts from coro objects - this is agruably more |
|
|
28 | correct, but mostly allows sharing of cctxs between coro and state |
|
|
29 | objects, for added memory savings and speed increases. |
|
|
30 | - bumped $Coro::POOL_RSS up to 32kb by default. |
|
|
31 | - no longer set the optype to OP_CUSTOM, as B::* understandably |
|
|
32 | doesn't like this very much (and we *are* a type of entersub). |
|
|
33 | - implement state cloning, just to prove that call/cc can be done. |
|
|
34 | - automatically load Coro::AnyEvent in Coro::Handle. |
|
|
35 | - wrap ->cancel calls in eval inside Coro::Handle as EV watchers |
|
|
36 | do not have this method (and don't need it either). |
|
|
37 | - speed up generic anyevent methods in Coro::Handle by using rouse |
|
|
38 | callbacks. |
|
|
39 | - allow coroutines in $Coro::IDLE, speeding up Coro::AnyEvent and |
|
|
40 | others. It also makes the debugger happier, as you can trace |
|
|
41 | through the idle threads now. |
|
|
42 | - add comppad_name* and hints ($^H, %^H) to per-thread variables. |
|
|
43 | - eg/event was pretty broken. |
|
|
44 | - better 5.8.6 compatibility. |

|
|
94 | making signals reliable for the first time. |

98 | a normal async is now very small. |
