If we 84 had any events set on the fd before, and we want any events to remain on 85 the fd, we need to say op="MOD" and set events=the events we want to 86 remain. But if we want to delete the last event, we say op="DEL" and 87 set events=(any non-null pointer). 88 89 [*0] Actually, the Python script has gotten a bit more complicated, to 90 support EPOLLRDHUP. 91 92 [*1] This MOD is only a guess. MOD might fail with ENOENT if the file was 93 closed and a new file was opened with the same fd. If so, we'll retry 94 with ADD. 95 96 [*2] We can't replace this with a no-op even if old_events is the same as 97 the new events: if the file was closed and reopened, we need to retry 98 with an ADD. (We do a MOD in this case since "no change" is more 99 common than "close and reopen", so we'll usually wind up doing 1 100 syscalls instead of 2.) 101 102 [*3] This ADD is only a guess. There is a fun Linux kernel issue where if 103 you have two fds for the same file (via dup) and you ADD one to an 104 epfd, then close it, then re-create it with the same fd (via dup2 or an 105 unlucky dup), then try to ADD it again, you'll get an EEXIST, since the 106 struct epitem is not actually removed from the struct eventpoll until 107 the file itself is closed. 108 109 EV_CHANGE_ADD==1 110 EV_CHANGE_DEL==2 111 EV_READ ==2 112 EV_WRITE ==4 113 EV_CLOSED ==0x80 114 115 Bit 0: close change is add 116 Bit 1: close change is del 117 Bit 2: read change is add 118 Bit 3: read change is del 119 Bit 4: write change is add 120 Bit 5: write change is del 121 Bit 6: old events had EV_READ 122 Bit 7: old events had EV_WRITE 123 Bit 8: old events had EV_CLOSED 124 */ 125 126 #define EPOLL_OP_TABLE_INDEX(c) \ 127 ( (((c)->close_change&(EV_CHANGE_ADD|EV_CHANGE_DEL))) | \ 128 (((c)->read_change&(EV_CHANGE_ADD|EV_CHANGE_DEL)) << 2) | \ 129 (((c)->write_change&(EV_CHANGE_ADD|EV_CHANGE_DEL)) << 4) | \ 130 (((c)->old_events&(EV_READ|EV_WRITE)) << 5) | \ 131 (((c)->old_events&(EV_CLOSED)) << 1) \ 132 ) 133 134 #if EV_READ != 2 || EV_WRITE != 4 || EV_CLOSED != 0x80 || EV_CHANGE_ADD != 1 || EV_CHANGE_DEL != 2 135 #error "Libevent's internals changed!
