* Simplify copy_file callsJosh Stone2009-09-281-8/+2
| | | | | | | | | | | | | | Every single copy_file call we had was converting strings to char*, printing the same error message, and optionally printing the same verbose string. Let's canonicalize that. * util.cxx (copy_file): Take string filenames, add a verbose flag, and consolidate the message printing. * cache.cxx (add_to_cache): Pass strings and remove message printing.

* Unify lex_cast* and avoid string copiesJosh Stone2009-09-021-2/+2
| | | | | | | | | | | | | | | We always use lex_cast either to string or from string, so I made that explicit, and got rid of some string copies in the process. There was also stringify(), which was redundant to lex_cast<string>. We also always used lex_cast_hex to string, so that's now hard-coded and again eliminated a string copy. For lex_cast_qstring<string>, there's no need to write the streamify the input, so a specialization now operates directly on the input. Hopefully this is a bit cleaner, and I do measure it to be a little faster on scripts with many probes.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We hereby no longer try to manipulate process groups in any way. We don't set a private process group, and we never kill() our entire group either. Instead of using system(), we now have a stap_system() which saves the child PID, so when we get a terminating signal we can pass it along to the child. Signals sent through the TTY have always worked, since the TTY sends it to the entire pgrp. However, if we're running as part of a wrapper script or GUI, which may not have a separate process group for stap, we still would like to allow "kill -TERM $STAPPID" to terminate stap nicely. There's still a short window of failure in the time that staprun is active, because we can't kill a setuid process from a user process. Once staprun drops privileges and execs to stapio though, everything should work fine.
