Just stylistic comments I already had, but holding off on the rest of the review as we discussed.

Some stylist comments.
I still want to discuss the main logic interactively since I don't fully understand some of it.

It looks like in this case you don't set mask.

Oh, I guess this is just relying on the variable initializing by default to 0 so the ands do the right thing.
windows.go
Outdated

Do you need to return in this case? Otherwise we send two events.

Jira: DA-992
For each rename action on a file, two syscall event is generated:
1-
FILE_ACTION_RENAMED_OLD_NAMEand2-
FILE_ACTION_RENAMED_NEW_NAME.Here I assumed that the first one is followed by the second one.
Then one fsnorify RENAME event is generated.
RENAME event has the file's oldName set up.
the
OldNameattribute is added to theEventstruct of fsnotify.The system call of
FILE_ACTION_RENAMED_OLD_NAMEholds the file's old name. Upon receiving this syscall event,watcher.renameis set up with the file's old name which serves as a state variable. No fsnotify event is created.The system call of
FILE_ACTION_RENAMED_NEW_NAMEholds the file's new name. A RENAME fsnotify event is created with file's old name,watcher.rename, asOldNameattribute .Cases:
receive
FILE_ACTION_RENAMED_NEW_NAMEandwatcher.renamehas a value, perfect case, a RENAME event is generated.receive any syscall rather than
FILE_ACTION_RENAMED_NEW_NAMEandwatcher.renamehas a value, first a RENAME event is created with empty name and the OldName iswatcher.renamevalue, then the syscall event is handled.receive
FILE_ACTION_RENAMED_NEW_NAMEandwatcher.renamehas no value, a RENAME event is generated with an empty oldName.Tests:
in imtegration_test.go
TestFsnotifyMultipleRenames():
generates 1000 rename action and checks if the RENAME attribute is set up correctly and all of the events are received.
TestFsnotifyRenameEventAttributes():
Checks if the
OldNameattribute is set up correctly for a rename event
