| 4 | TODO: make ev_once timeout=0 useful, and make I/O always win. |
4 | - further optimise away the EPOLL_CTL_ADD/MOD combo in the epoll |
|
|
5 | backend by assuming the kernel event mask hasn't changed if |
|
|
6 | ADD fails with EEXIST. |
|
|
7 | - work around spurious event notification bugs in epoll by using |
|
|
8 | a 32-bit generation counter. recreate kernel state if we receive |
|
|
9 | spurious notifications or unwanted events. this is very costly, |
|
|
10 | but I didn't come up with this horrible design. |
|
|
11 | - use memset to initialise most arrays now and do away with the |
|
|
12 | init functions. |
|
|
13 | - expand time-out strategies into a "Be smart about timeouts" section. |
|
|
14 | - drop the "struct" from all ev_watcher declarations in the |
|
|
15 | documentation and did other clarifications (yeah, it was a mistake |
|
|
16 | to have a struct AND a function called ev_loop). |
|
|
17 | - fix a bug where ev_default would not initialise the default |
|
|
18 | loop again after it was destroyed with ev_default_destroy. |
|
|
19 | - rename syserr to ev_syserr to avoid name clashes when embedding, |
|
|
20 | do similar changes for event.c. |

|
|
23 | - disable inotify usage on linux <2.6.25, as it is broken |
|
|
24 | (reported by Yoann Vandoorselaere). |
|
|
25 | - ev_stat errornously would try to add inotify watchers |
|
|
26 | even when inotify wasn't available (this should only |
|
|
27 | have a performance impact). |
|
|
28 | - ev_once now passes both timeout and io to the callback if both |
|
|
29 | occur concurrently, instead of giving timeouts precedence. |
|
|
30 | - disable EV_USE_INOTIFY when sys/inotify.h is too old. |
