Keith Winstein b4263b354e Check for paths.h and make sure we have _PATH_BSHELL 2012-04-16 17:51:52 -04:00
Jay Freeman (saurik) 2462434390 Use _PATH_BSHELL for "/bin/sh" and fix argv[0]. 
The previous code had the following issues:

1) hardcoded the path of /bin/sh (should use paths.h)
2) threw away the variable with the fallback shell
3) prepended - to the path rather than the shell name
4) added a - before explicit chosen non-shell commands

Closes #199.

Ed Schouten 033953dcd2 Don't leak utmpx entries on shutdown. 
As far as I know, for all implementations of libutempter, the
utempter_remove_added_record() function depends on the file descriptor
passed to utempter_add_record() to still be valid. The reason for this,
is that this file descriptor is propagated to the setuid utility that is
responsible for modifying utmpx.

Modify the code to remove the utmpx entry before closing the
pseudo-terminal master device. While there, simply use
utempter_remove_record(), which takes the file descriptor explicitly.
The advantage is that this prevents potential foot-shooting in the
future. Visual inspection of the source code will make it more obvious
that utempter depends on the file descriptor.

Closes #179.

Keegan McAllister 280400152d Replace one find_if with a loop 
g++/libstdc++ 4.1.2 is unhappy with this use of bind2nd, possibly because the
argument is a reference.  This is a problem for EL5.
