- Here are the values we're masking off to decide what operations to do.
- Note that since EV_READ|EV_WRITE.
-
- Note also that this table is a little sparse, since ADD+DEL is
- nonsensical ("xxx" in the list below.)
-
- Note also also that we are shifting old_events by only 5 bits, since
- EV_READ is 2 and EV_WRITE is 4.
-
- The table was auto-generated with a python script, according to this
- pseudocode:
-
- If either the read or the write change is add+del:
- This is impossible; Set op==-1, events=0.
- Else, if either the read or the write change is add:
- Set events to 0.
- If the read change is add, or
- (the read change is not del, and ev_read is in old_events):
- Add EPOLLIN to events.
- If the write change is add, or
- (the write change is not del, and ev_write is in old_events):
- Add EPOLLOUT to events.
-
- If old_events is set:
- Set op to EPOLL_CTL_MOD [*1,*2]
- Else:
- Set op to EPOLL_CTL_ADD [*3]
-
- Else, if the read or the write change is del:
- Set op to EPOLL_CTL_DEL.
- If the read change is del:
- If the write change is del:
- Set events to EPOLLIN|EPOLLOUT
- Else if ev_write is in old_events:
- Set events to EPOLLOUT
- Set op to EPOLL_CTL_MOD
- Else
- Set events to EPOLLIN
- Else:
- {The write change is del.}
- If ev_read is in old_events:
- Set events to EPOLLIN
- Set op to EPOLL_CTL_MOD
- Else:
- Set the events to EPOLLOUT
-
- Else:
- There is no read or write change; set op to 0 and events to 0.
-
- The logic is a little tricky, since we had no events set on the fd before,
- we need to set op="ADD" and set events=the events we want to add. If we
- had any events set on the fd before, and we want any events to remain on
- the fd, we need to say op="MOD" and set events=the events we want to
- remain. But if we want to delete the last event, we say op="DEL" and
- set events=(any non-null pointer).
-
- [*1] This MOD is only a guess. MOD might fail with ENOENT if the file was
- closed and a new file was opened with the same fd. If so, we'll retry
- with ADD.
-
- [*2] We can't replace this with a no-op even if old_events is the same as
- the new events: if the file was closed and reopened, we need to retry
- with an ADD. (We do a MOD in this case since "no change" is more
- common than "close and reopen", so we'll usually wind up doing 1
- syscalls instead of 2.)
-
- [*3] This ADD is only a guess. There is a fun Linux kernel issue where if
- you have two fds for the same file (via dup) and you ADD one to an
- epfd, then close it, then re-create it with the same fd (via dup2 or an
- unlucky dup), then try to ADD it again, you'll get an EEXIST, since the
- struct epitem is not actually removed from the struct eventpoll until
- the file itself is closed.

+ Here are the values we're masking off to decide what operations to do.
+ Note that since EV_READ|EV_WRITE.
+
+ Note also that this table is a little sparse, since ADD+DEL is
+ nonsensical ("xxx" in the list below.)
+
+ Note also also that we are shifting old_events by only 5 bits, since
+ EV_READ is 2 and EV_WRITE is 4.
+
+ The table was auto-generated with a python script, according to this
+ pseudocode:[*0]
+
+ If either the read or the write change is add+del:
+ This is impossible; Set op==-1, events=0.
+ Else, if either the read or the write change is add:
+ Set events to 0.
+ If the read change is add, or
+ (the read change is not del, and ev_read is in old_events):
+ Add EPOLLIN to events.
+ If the write change is add, or
+ (the write change is not del, and ev_write is in old_events):
+ Add EPOLLOUT to events.
+
+ If old_events is set:
+ Set op to EPOLL_CTL_MOD [*1,*2]
+ Else:
+ Set op to EPOLL_CTL_ADD [*3]
+
+ Else, if the read or the write change is del:
+ Set op to EPOLL_CTL_DEL.
+ If the read change is del:
+ If the write change is del:
+ Set events to EPOLLIN|EPOLLOUT
+ Else if ev_write is in old_events:
+ Set events to EPOLLOUT
+ Set op to EPOLL_CTL_MOD
+ Else
+ Set events to EPOLLIN
+ Else:
+ {The write change is del.}
+ If ev_read is in old_events:
+ Set events to EPOLLIN
+ Set op to EPOLL_CTL_MOD
+ Else:
+ Set the events to EPOLLOUT
+
+ Else:
+ There is no read or write change; set op to 0 and events to 0.
+
+ The logic is a little tricky, since we had no events set on the fd before,
+ we need to set op="ADD" and set events=the events we want to add. If we
+ had any events set on the fd before, and we want any events to remain on
+ the fd, we need to say op="MOD" and set events=the events we want to
+ remain. But if we want to delete the last event, we say op="DEL" and
+ set events=(any non-null pointer).
+
+ [*0] Actually, the Python script has gotten a bit more complicated, to
+ support EPOLLRDHUP.
+
+ [*1] This MOD is only a guess. MOD might fail with ENOENT if the file was
+ closed and a new file was opened with the same fd. If so, we'll retry
+ with ADD.
+
+ [*2] We can't replace this with a no-op even if old_events is the same as
+ the new events: if the file was closed and reopened, we need to retry
+ with an ADD. (We do a MOD in this case since "no change" is more
+ common than "close and reopen", so we'll usually wind up doing 1
+ syscalls instead of 2.)
+
+ [*3] This ADD is only a guess. There is a fun Linux kernel issue where if
+ you have two fds for the same file (via dup) and you ADD one to an
+ epfd, then close it, then re-create it with the same fd (via dup2 or an
+ unlucky dup), then try to ADD it again, you'll get an EEXIST, since the
+ struct epitem is not actually removed from the struct eventpoll until
+ the file itself is closed.
