8 | TODO: Coro/Intro |
| 9 | 5.0 |
9 | - wrote a small introduction - Coro::Intro. |
|
|
10 | - convert Coro::Timer, Coro::Select and Coro::Util to rouse API. |
|
|
11 | - Coro::Select did errornously dup the file descriptors |
|
|
12 | and didn't work with all AnyEvent backends. |
|
|
13 | - disassociate c contexts from coro objects - this is agruably more |
|
|
14 | correct, but mostly allows sharing of cctxs between coro and state |
|
|
15 | objects, for added memory savings and speed increases. |
|
|
16 | - bumped $Coro::POOL_RSS up to 32kb by default. |
|
|
17 | - no longer set the optype to OP_CUSTOM, as B::* understandably |
|
|
18 | doesn't like this very much (and we *are* a type of entersub). |
|
|
19 | - implement state cloning, just to prove that call/cc can be done. |
|
|
20 | - automatically load Coro::AnyEvent in Coro::Handle. |
|
|
21 | - wrap ->cancel calls in eval inside Coro::Handle as EV watchers |
|
|
22 | do not have this method (and don't need it either). |
|
|
23 | - speed up generic anyevent methods in Coro::Handle by using rouse |
|
|
24 | callbacks. |
|
|
25 | - allow coroutines in $Coro::IDLE, speeding up Coro::AnyEvent and |
|
|
26 | others. It also makes the debugger happier, as you can trace |
|
|
27 | through the idle threads now. |
|
|
28 | - eg/event was pretty broken. |
|
|
29 | - better 5.8.6 compatibility. |
