664661 - PR_Select() fails test selct_er

Status: NEW

(NSPR :: NSPR, defect)

Description

[Mikhail T.]

The (unpatched) sect_er.c test hangs indefinitely, because PR_Select() on FreeBSD fails to detect, that it was passed an already closed file-descriptor.

Attachment: A test program calling socket() and select() directly, without NSPR

The attached program behaves the same on both Linux and FreeBSD. On both systems, the output is:

% ./select-test 
Trying to read-select on closed read-fd
select: Bad file descriptor
% ./select-test foo
Trying to write-select on closed write-fd
select: Success
% ./select-test foo bar
Trying to read-select on closed TCP-socket
select: Success

This suggests, the test should be failing on Linux as well (select-ing on an already closed TCP-socket returns success instead of reporting bad file descriptor), but it does not...
