3ece4c837f Call tcgetpgrp() in the parent, not the child and have the child spin 
until it is granted.  Fixes a race on darwin.

52f3374ce3 Only use TIOCNOTTY in the non-setsid case. If no TIOCSCTTY, just 
reopen slave.

7411b071e4 In script mode, if the command is killed by a signal, print the 
signal description as well as a core dump notification like the
shell does.

7bfe0fe957 Add missing WUNTRACED and store the signal that stopped the grandchild 
in suspended, not signo.

0d04ffc40c Associate the grandchild's pgrp with the tty instead of the child's 
and just get suspend notifications via SIGCHLD instead of directly.
This fixes a hang with programs that try to set terminal attributes
and is more consistent with how the shell handles things.

88b93973fe Run command in its own pgrp (like the shell does) for easier signalling. 
No need to relay SIGINT or SIGQUIT to parent, just send to grandchild.
Don't want grandchild stopped events in the child (only termination).
Flush output after suspending grandchild before signalling parent.

f44c2261fd Don't set stdout to blocking mode when flushing remaining output. It 
can cause us to hang when trying to exit.  Need to investigate why.

03e3ca08db Handle SIGTTOU and remove some debugging. 2009-10-11 13:25:23 +00:00
Todd C. Miller
9afe6a842e Back out revision 1.10 as the signal that interrupts us may be 
SIGTTOU or SIGTTIN which the caller must handle.

09a7bb78fe Apparently we need to send SIGSTOP to the command as well as ourself 
when we get SIGTSTP, the kernel doesn't automatically stop the process
for us.

2cf1b81abf Use an extra process to act as the glue bewteen the sessions 
associated with the user's controlling tty (what the shell uses)
and the tty that sudo is using to do its logging.  Basically, this
means that if we get, e.g. SIGTSTP from the process sudo is running,
we relay the signal to the parent so it's shell can do the job control.

378d15f8fc Always update the stashed mtime of the temp file instead of using what 
we have for the original because the time resolution of the filesystem the
temporary is on may not match that of the filesystem that holds the original.
Should fix bz #371 found by Philippe Levan.

5636a93f58 Use cbreak mode instead of raw mode and add signal handlers to restore 
the tty on interrupt.

fe9fc5ad1b Retain NL to NLCR conversion on the real tty and skip it on the pty 
we allocate.  That way, if stdout is not a pty there are no extra carriage
returns.

0d9e1e7b6d Instead of messing with line endings, just set terminal to raw mode 
in sudoreplay.

929f13fdfc When copying the terminal attributes to the pty, be sure not to set ONLCR. 
This prevents extra carriage returns from ending up in the script output file.

7bb38284b0 Go back to dropping out of the select() loop when the process dies; Linux 
ptys apparently don't behave the same as BSD in regards to select().
No need to flush remaining output to the transcript, only to stdout.
Add back code to check the master pty for additional data when we exit
the main select loop.
