|
|
9 | - handle backends with minimum wait time a bit better by not |
|
|
10 | waiting in the presence of already-expired timers |
|
|
11 | (behaviour reported by Felipe Gasper). |
|
|
12 | - new feature: use timerfd to detect timejumps quickly, |
|
|
13 | can be disabled with the new EVFLAG_NOTIMERFD loop flag. |
|
|
14 | - document EV_USE_SIGNALFD feature macro. |

18 | LINUX_VERSION_CODE, the most direct test I could find. |
|
|
19 | - fix a bug in the io_uring backend that polled the wrong |

27 | - linuxaio backend resulted in random memory corruption |
|
|
28 | when loop is forked. |
|
|
29 | - linuxaio backend might have tried to cancel an iocb |
|
|
30 | multiple times (was unable to trigger this). |
|
|
31 | - linuxaio backend now employs a generation counter to |
|
|
32 | avoid handling spurious events from cancelled requests. |
|
|
33 | - io_cancel can return EINTR, deal with it. also, assume |
|
|
34 | io_submit also returns EINTR. |
|
|
35 | - fix some other minor bugs in linuxaio backend. |
|
|
36 | - ev_tstamp type can now be overriden by defining EV_TSTAMP_T. |
|
|
37 | - cleanup: replace expect_true/false and noinline by their |
|
|
38 | libecb counterparts. |
|
|
39 | - move syscall infrastructure from ev_linuxaio.c to ev.c. |
|
|
40 | - prepare io_uring integration. |
|
|
41 | - tweak ev_floor. |
|
|
42 | - epoll, poll, win32 Sleep and other places that use millisecond |
|
|
43 | reslution now all try to round up times. |
|
|
44 | - solaris port backend didn't compile. |
|
|
45 | - abstract time constants into their macros, for more flexibility. |
