Before ::read() is called, open() is called. ::open() is suppossed to
create the empty session data, if no data for the given session exist.
This empty data string should then be returned from ::read(). If
::read() fails to read the data, it should return false (or actually any
non-string value in the current implementation) to signal failure.
I might be confused but the session id is not passed to ::open() so how
is it supposed to create the empty session data ? By using session_id ?
Ah, right, ::open() is not supposed to create the empty session data.
This can be done in ::read(); the built-in "files" handler does this,
for instance; if the file does not exist and can't be created, ::read()
fails.
OK, that was the only explanation that made sense. Do we agree that the
doc could be improved by stating this more clearly ?
