If we 82 had any events set on the fd before, and we want any events to remain on 83 the fd, we need to say op="MOD" and set events=the events we want to 84 remain. But if we want to delete the last event, we say op="DEL" and 85 set events=(any non-null pointer). 86 87 [*0] Actually, the Python script has gotten a bit more complicated, to 88 support EPOLLRDHUP. 89 90 [*1] This MOD is only a guess. MOD might fail with ENOENT if the file was 91 closed and a new file was opened with the same fd. If so, we'll retry 92 with ADD. 93 94 [*2] We can't replace this with a no-op even if old_events is the same as 95 the new events: if the file was closed and reopened, we need to retry 96 with an ADD. (We do a MOD in this case since "no change" is more 97 common than "close and reopen", so we'll usually wind up doing 1 98 syscalls instead of 2.) 99 100 [*3] This ADD is only a guess. There is a fun Linux kernel issue where if 101 you have two fds for the same file (via dup) and you ADD one to an 102 epfd, then close it, then re-create it with the same fd (via dup2 or an 103 unlucky dup), then try to ADD it again, you'll get an EEXIST, since the 104 struct epitem is not actually removed from the struct eventpoll until 105 the file itself is closed. 106 107 EV_CHANGE_ADD==1 108 EV_CHANGE_DEL==2 109 EV_READ ==2 110 EV_WRITE ==4 111 EV_CLOSED ==0x80 112 113 Bit 0: close change is add 114 Bit 1: close change is del 115 Bit 2: read change is add 116 Bit 3: read change is del 117 Bit 4: write change is add 118 Bit 5: write change is del 119 Bit 6: old events had EV_READ 120 Bit 7: old events had EV_WRITE 121 Bit 8: old events had EV_CLOSED 122*/ 123 124#define EPOLL_OP_TABLE_INDEX(c) \ 125 ( (((c)->close_change&(EV_CHANGE_ADD|EV_CHANGE_DEL))) | \ 126 (((c)->read_change&(EV_CHANGE_ADD|EV_CHANGE_DEL)) << 2) | \ 127 (((c)->write_change&(EV_CHANGE_ADD|EV_CHANGE_DEL)) << 4) | \ 128 (((c)->old_events&(EV_READ|EV_WRITE)) << 5) | \ 129 (((c)->old_events&(EV_CLOSED)) << 1) \ 130 ) 131 132#if EV_READ != 2 || EV_WRITE != 4 || EV_CLOSED != 0x80 || EV_CHANGE_ADD != 1 || EV_CHANGE_DEL != 2 133#error "Libevent's internals changed!
