* PR11405: Warn and continue for parsing errors in tapsetsJosh Stone2010-03-201-1/+4
| | | | | | | | | | | | When we start seeing tapsets provided by third parties, any errors in their files should not be fatal to us. Since we don't really know which tapsets are our own, this leniency applies to all. * main.cxx (main): Warn on tapset errors, but continue unless -W. * testsuite/parseko/bad_tapset/foo.stp: New bogus tapset. * testsuite/parseko/bad_tapset.stp: Check that "-W -I bad_tapset" fails. * testsuite/parseok/bad_tapset.stp: Check that "-I bad_tapset" succeeds. * testsuite/parseok/all_tapsets.stp: Check -W with the default tapsets.
* PR909: store kernel exported symbols in session objectFrank Ch. Eigler2010-03-181-3/+36
| | | | | | | * session.h (kernel_exports): New field. * main.cxx (parse_kernel_exports): Fill it. * tapset-perfmon.cxx (perf_builder::build): Check it for our pal perf_event_create_kernel_counter.

* PR10831: Remember derived "aliases" in the probe chainJosh Stone2010-03-161-4/+25
| | | | | | | | | | | | | SDT and label probes are not really final probe types themselves, but rather they get translated into some other final type. This patch preserves this relationship as if SDT and label probes were dynamically generated aliases. * elaborate.cxx (probe::create_alias): New, fake an alias_derived_probe. * tapsets.cxx (query_label): Append the label name as an alias. (sdt_query::handle_query_module): Let convert_location do the alias. (sdt_query::convert_location): Translate the location using an alias. * main.cxx (printscript): Elaborate the derivation debug dump.
* Add startswith/endswith helpersJosh Stone2010-03-111-7/+4
| | | | | Inspired by the Python equivalents, these new utility functions just make it a little cleaner to match at the beginning or end of a string.
* PR11246 cont'd: Add options for cache controlJosh Stone2010-03-021-0/+31
| | | | | | | | | | | | | | | | --disable-cache : turn off all caching --clean-cache : clean up stale entries and then quit --poison-cache : force regeneration of items that would have hit the cache These are undocumented for now, until we decide whether they are generally useful. * main.cxx (main): Parse the new options. * session.h (systemtap_session): Add poison_cache; document the others. * clean.cxx (clean_cache): No longer static. (get_stapconf_from_cache, get_script_from_cache): Respect poison. * tapsets.cxx (tracepoint_builder::get_tracequery_module): Ditto. (dwarf_cast_expanding_visitor::filter_special_modules): Ditto.
* PR11246 cont'd: Separate script/stapconf cachingJosh Stone2010-03-021-3/+11
| | | | | | | | | | | I'm separating the caching and creation logic for stapconf, so it can be conditionalized on s.use_cache instead of s.use_script_cache. * session.h (systemtap_session): Store base_hash for better reuse. * hash.cxx (get_base_hash): Get the base from the session, or build it. (find_hash): Split into separate script/stapconf versions. * cache.cxx (add_to_cache, get_from_cache): Ditto. * main.cxx (main): Adapt caller, and delay stapconf until pass-4.
* Move pass-3/4 cache checks after the reported pass-2 endJosh Stone2010-03-021-8/+9
| | | | * main.cxx (main): Reorganize the end of pass-2 a bit.
* PR11246: Add more granular cache controlJosh Stone2010-03-021-7/+8
| | | | | | | | | | | | | | There are some module options that require us to disable caching for the script, but before now this had a global effect. There are some cache objects, like tracepoint and @cast query modules, which we would like to cache even when the script itself needs to be uncached. * session.h (systemtap_session): New use_script_cache flag. * main.cxx (main): -m & -k can just disable the script cache. Failure to create the cache directories still disables all caching. * hash.cxx (create_hashdir): Failure disables all caching. * cache.cxx (add_to_cache): Failure only toggles the script caching. If the stapconf fails though, we don't need to block the .ko reuse.

* 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. (get_from_cache): Ditto. * main.cxx (main): Ditto. * tapsets.cxx (tracepoint_builder::get_tracequery_module): Ditto. (dwarf_cast_expanding_visitor::filter_special_modules): Ditto.

* 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.
