|
|
8 | - queueing pending watchers of higher priority from a watcher now invokes |
|
|
9 | them in a timely fashion (reported by Denis Bilenko). |
|
|
10 | - add throw() to all libev functions that cannot throw exceptions, for |
|
|
11 | further code size decrease when compiling for C++. |
|
|
12 | - add throw () to callbacks that must not throw exceptions (allocator, |
|
|
13 | syserr, loop acquire/release, periodic reschedule cbs). |
|
|
14 | - fix event_base_loop return code, add event_get_callback, event_base_new, |
|
|
15 | event_base_get_method calls to improve libevent 1.x emulation and add |
|
|
16 | some libevent 2.x funcitonality (based on a patch by Jeff Davey). |
|
|
17 | - add more memory fences to fix a bug reported by Jeff Davey. Better |
|
|
18 | be overfenced than underprotected. |
|
|
19 | - ev_run now returns a boolean status (true meaning watchers are |
|
|
20 | still active). |
|
|
21 | - ev_once: undef EV_ERROR in ev_kqueue.c, to avoid clashing with |
|
|
22 | libev's EV_ERROR (reported by 191919). |
|
|
23 | - (ecb) add memory fence support for xlC (Darin McBride). |
|
|
24 | - (ecb) add memory fence support for gcc-mips (Anton Kirilov). |
|
|
25 | - (ecb) add memory fence support for gcc-alpha (Christian Weisgerber). |
|
|
26 | - work around some kernels losing file descriptors by leaking |
|
|
27 | the kqueue descriptor in the child. |
|
|
28 | - include sys/syscall.h instead of plain syscall.h. |
|
|
29 | - check for io watcher loops in ev_verify, check for the most |
|
|
30 | common reported usage bug in ev_io_start. |
|
|
31 | - chose socket vs. WSASocket at compiletime using EV_USE_WSASOCKET. |
|
|
32 | - always use WSASend/WSARecv directly on windows, hoping that this |
|
|
33 | works in all cases (unlike read/write/send/recv...). |
|

|
36 | - INCOMPATIBLE CHANGE: ev_timer_again now clears the pending status, as |
|
|
37 | was documented already, but not implemented in the repeating case. |
