|
|
8 | - handle backends with minimum wait time a bit better by not |
|
|

|
|
10 | (behaviour reported by Felipe Gsper). |
|
|
11 | |
|
|
12 | 4.30 (EV only) |
|
|
13 | - change non-autoconf test for __kernel_rwf_t by testing |
|
|
14 | LINUX_VERSION_CODE, the most direct test I could find. |
|
|
15 | - fix a bug in the io_uring backend that polled the wrong |
|
|
16 | backend fd, causing it to not work in many cases. |
|
|
17 | |
|
|
18 | 4.29 (EV only) |
|
|
19 | - add io uring autoconf and non-autoconf detection. |
|
|
20 | - disable io_uring when some header files are too old. |
|

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