12 | - add throw() to all libev functions that cannot throw exceptions, for |
|
|
13 | further code size decrease when compiling for C++. |
|
|
14 | - add throw () to callbacks that must not throw exceptions (allocator, |
|
|
15 | syserr, loop acquire/release, periodic reschedule cbs). |
|
|
16 | - fix event_base_loop return code, add event_get_callback, event_base_new, |
|
|
17 | event_base_get_method calls to improve libevent 1.x emulation and add |
|
|
18 | some libevent 2.x funcitonality (based on a patch by Jeff Davey). |
|
|
19 | - add more memory fences to fix a bug reported by Jeff Davey. Better |
|
|
20 | be overfenced than underprotected. |
|
|
21 | - ev_run now returns a boolean status (true meaning watchers are |
|
|
22 | still active). |
|
|
23 | - ev_once: undef EV_ERROR in ev_kqueue.c, to avoid clashing with |
|
|
24 | libev's EV_ERROR (reported by 191919). |
|
|
25 | - (ecb) add memory fence support for xlC (Darin McBride). |
|
|
26 | - (ecb) add memory fence support for gcc-mips (Anton Kirilov). |
|
|
27 | - (ecb) add memory fence support for gcc-alpha (Christian Weisgerber). |
|
|
28 | - work around some kernels losing file descriptors by leaking |
|
|
29 | the kqueue descriptor in the child. |
|
|
30 | - include sys/syscall.h instead of plain syscall.h. |

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

35 | - new compiletime symbols: EV_NO_SMP and EV_NO_THREADS. |
