| | | | | * main.cxx (main): exit() instead of printing usage for most errors. Also support --help.

* rhbz 560890: preserve -L/-l variable orderingNobuhiro Tachino2010-02-021-12/+41
| | | | | | Switch to list<string> from set<string> for collecting available $var lists. Use O(N**2) list-uniqueifier that preserves initial ordering.
* PR11105: robustify stap-serverFrank Ch. Eigler2010-01-151-2/+9
| | | | | | | | | | | * main.cxx (main): Always downgrade client-provided -p5 to -p4. * stap-client (unpack_response): Sanitize stdout due to same. * stap-server-connect.c: Eliminate a bunch of globals. (handle_connection): Make things locals instead. Base tmp files on $TMPDIR. (spawn_and_wait): New helper function. (handleRequest): New monster function to inline rest of old stap-server-request.
* Fix rawhide compile problem.David Smith2010-01-141-1/+1
| | | | | * main.cxx (getmemusage): On rawhide systems, 'getpagesize()' has been deprecated. Substitute 'sysconf(_SC_PAGESIZE)'.

* Accept relative user module paths for -d.Mark Wielaard2009-11-131-5/+13
| | | | | | | | | | | | When using relative (non-canonical) paths for user modules one would get a confusing WARNING: missing unwind/symbol data for module 'bin/test'. Also unless the path started with '/' the task_finder wouldn't start. By checking that the given file can be made absolute (canonicalized) both issues are resolved and the user module will be correctly identified at both translation and runtime. * main.cxx (main): case 'd' try canonicalize_file_name() the argument first to identify user modules.

* 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.
