8 | - convert Coro::Timer, Coro::Select and Coro::Util to rouse API. |
| 9 | - NEW ARCHITECTURE: use 4.912 for the stable version. |
9 | - Coro::Select did errornously dup the file descriptors |
|
|
10 | and didn't work with all AnyEvent backends. |
|

24 | - fix a longstanding bug where calling terminate on a coro that |
|
|
25 | was waiting for a semaphore that was just becoming available |
|
|
26 | would cause a deadlock (semaphore would get into a state where |
|
|
27 | it was available but waiters were still blocked). |
|
|
28 | - calling throw on a coroutine that is waiting for a semaphore will |
|
|
29 | no longer make it acquire the semaphore (and thus leak a count). |

|
|
32 | - new functions Coro::rouse_cb and Coro::rouse_wait for easier |
|
|
33 | conversion of callback-style to blocking-style. |
|
|
34 | - new methods $coro->schedule_to and ->cede_to, to specifically |

35 | schedule or cede to a specific coroutine. |
|
|
36 | - new function Coro::Semaphore::wait. |
|

|
|
52 | - used new SLF interface to speed up Coro::AIO by roughly a factor of |
|
|
53 | four and reduce its memory usage considerably. |
|
|
54 | - implement Coro::SemaphoreSet purely in terms of Coro::Semaphore, |
|
|
55 | for a nice speedup and vastly more correct behaviour. Also implement |
|
|
56 | a new method "sem" to get at the underlying semaphore object. |
|
|
57 | - implement Coro::Channel in terms of Coro::Semaphore, for a moderate |
|
|
58 | (in comparison) 20-40% speedup. |
|
|
59 | - used new SLF interface to reimplement Coro::Signal gaining |
|
|
60 | some unknown (because I was too lazy), but certain, speedup, and also |
|
|
61 | making signals reliable for the first time. |
|
|
62 | - used new SLF interface and other optimisations to speed up async_pool |
|
|
63 | by a factor of two. It also doesn't rely on perl's exception mechanism |
|
|
64 | to exit anymore. The overhead for terminating an async_pool, coro over |
|
|
65 | a normal async is now very small. |
|

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