240642399b Save the controlling tty process group before suspending so we can 
restore it when we resume.  Fixes job control problems on Linux
caused by the previous attemp to fix resuming a shell when I/O
logging not enabled.

caefd1abdc In handle_signals(), restart the read() on EINTR to make sure we keep up 
with the signal pipe.  Don't return -1 on EAGAIN, it just means we have
emptied the pipe.

1496bfed6c Add support for adding a utmp entry when allocating a new pty. 
Requires the BSD login(3) or SYSV/POSIX getutent()/getutxent().
Currently only creates a new entry if the existing tty has
a utmp entry.

c833ff02b6 Add use_pty command_info flag for policies to indicate that a 
pty should be allocated even if no I/O logging is performed.

a11e4c8d72 If perform_io() fails, kill the child before exiting so it doesn't 
complain about connection reset.  We can get an I/O error if, for
example, and we get EIO reading from stdin.

66bea8c4c9 Read as many signals on the signal pipe as we can before returning. 2010-09-10 11:27:20 -04:00
Todd C. Miller
59399d55c3 Instead of using a array to store received signals, open a pipe and 
have the signal handler write the signal number to one end and
select() on the other end.  This makes it possible to handle signals
similar to I/O without race conditions.

2cef2bb5b0 When not logging I/O install a handler for SIGCONT and deliver it 
to the command upon resume.  Fixes bugzilla #431

e11e4efb8f Do I/O logging in the C locale so the floating point numbers in the 
timing file are not locale-dependent.

30fe4a067c Set usrinfo for AIX 
Set adminstrative domain for the process when looking up user's
    password or group info and when preparing for execve().
Include strings.h even if string.h exists since they may define
    different things.  Fixes warnings on AIX and others.
