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

|
|
27 | - new functions Coro::rouse_cb and Coro::rouse_wait for easier |
|
|
28 | conversion of callback-style to blocking-style. |
|
|
29 | - new methods $coro->schedule_to and ->cede_to, to specifically |
|
|
30 | schedule or cede to a specific coroutine. |
|
|
31 | - new function Coro::Semaphore::wait. |
|

|
|
47 | - used new SLF interface to speed up Coro::AIO by roughly a factor of |
|
|
48 | four and reduce its memory usage considerably. |
|
|
49 | - implement Coro::SemaphoreSet purely in terms of Coro::Semaphore, |
|
|
50 | for a nice speedup and vastly more correct behaviour. Also implement |
|
|
51 | a new method "sem" to get at the underlying semaphore object. |
|
|
52 | - implement Coro::Channel in terms of Coro::Semaphore, for a moderate |
|
|
53 | (in comparison) 20-40% speedup. |
|
|
54 | - used new SLF interface to reimplement Coro::Signal gaining |
|
|
55 | some unknown (because I was too lazy), but certain, speedup, and also |
|
|
56 | making signals reliable for the first time. |
|
|
57 | - used new SLF interface and other optimisations to speed up async_pool |
|
|
58 | by a factor of two. It also doesn't rely on perl's exception mechanism |
|
|
59 | to exit anymore. The overhead for terminating an async_pool, coro over |
|
|
60 | a normal async is now very small. |
|
|
61 | - sped up coroutine creation/destruction by 40%. |
|
|
62 | - forgot to include Coro/libcoro/README in the dist for all these years. |
|
|
63 | - work around a freebsd pthreads bug (manual testcancel is required as |
|
|
64 | pthread_cond_wait isn't a cancellation point on freebsd). |
|
|
65 | - use new rouse functions to speed up and simplify Coro::BDB. |
|
|
66 | - make "prefer perl native functions" work with threaded perls. |
|
|
67 | - condense Coro::Debug ps output, hint at v and w flags. |
|
|
68 | - (libcoro) lots of minor cleanups and portability improvements. |
