[Xapian-devel] Problems with /bin/cat and flintlock?

[Samuel Williams]

In my synthetic test, I got the following behavior when attached to /bin/cat:

# strace -p 2091
Process 2091 attached - interrupt to quit
read(0, 0x89e7000, 32768)               = ? ERESTARTSYS (To be restarted)
--- SIGHUP (Hangup) @ 0 (0) ---
read(0, "", 32768)                      = 0
close(0)                                = 0
close(1)                                = 0
close(2)                                = -1 EBADF (Bad file descriptor)
exit_group(0)                           = ?
Process 2091 detached

This seems like the desired behavior.

However, in the case where the WritableDatabase hung, I got the following behavior:

# strace -p 25694
Process 25694 attached - interrupt to quit
read(0, 0x859b000, 32768)               = ? ERESTARTSYS (To be restarted)
--- SIGHUP (Hangup) @ 0 (0) ---
read(0, 
^C <unfinished ...>
Process 25694 detached

Well, I'm not sure why there is a difference. Both processes were ignoring SIGHUP according to /proc/$pid/status

I'll keep on investigating.
