* Improved PR 11309 by fixing directory and file permissions.David Smith2010-03-091-2/+3
| | | | | * systemtap.spec: Fixed directory and file permissions on /usr/share/systemtap/runtime/uprobes and /var/log/stap-server.
* PR 11210 Eliminate man page collisionsWilliam Cohen2010-03-091-4/+4
| | | | | | | The various man pages for each systemtap probe and function are prepended with "probe::" and "function::" respectively to avoid collisions with other man3 pages with the same name. For example systemtap's strlen function was colliding with glibc's strlen function.
* Only use volatile for sdt.h arguments when needed.Stan Cox2010-03-091-55/+61
| | | | | sdt.h (VOLATILE_ARG): gcc 4.4.3 support for inline asm argument debug info means volatile is not needed.
* build: re-enable librpm checkingFrank Ch. Eigler2010-03-083-6/+19
| | | | | | * configure.ac: With AC_CHECK_LIB()'s four-parameter variant, the default AC_DEFINE etc. is removed, so restore the key parts by hand.

* PRs 11205, 11309: Specfile problems for stap-server:Dave Brolley2010-03-087-30/+33
| | | | | | | | - Use assigned gid/uid of 155/155 for stap-server. - Create stap-server group in main systemtap rpm. - Make uprobes runtime directory read/write/search by members of stap-server group in main systemtap rpm. - Keep stap-server log in %{_localstatedir}/log/stap-server/log
* PR 11338 (partial): Used '@defined()' in tty, scheduler, and vfs tapsets.David Smith2010-03-084-89/+39
| | | | | | | | | | * tapset/tty.stp: Used '@defined()' to remove kernel version checks. * tapset/scheduler.stp: Ditto. * tapset/vfs.stp: Used '@defined()' to remove kernel version checks. Also made several probe points optional instead of using kernel version checks to know when to include them. * testsuite/buildok/vfs_testcase.stp: Removed stap '-u' (unoptimized mode) switch, since '@defined()' doesn't work in unoptimized mode.

* Move semko/nineteen.stp to semokJosh Stone2010-03-061-2/+1
| | | | | | | | | The *ko tests are for things that SHOULD fail, but semko/nineteen is a test that should pass but often doesn't (due to inline var trouble). It should be in semok to set the expectation properly. It does pass on F12 now, but if we want to silence the error for older gcc, setup_kfail is the right approach.
* PR11352: Assign tokens to all SDT-synthesized elementsJosh Stone2010-03-062-12/+20
| | | | | | | * tapsets.cxx (sdt_query::convert_probe): Fix a few missing tokens. (sdt_var_expanding_visitor::visit_target_symbol): Ditto. * translate.cxx (c_unparser::record_actions): Add a defensive check, which perhaps someday can be an assertion instead.
* PR11342: Ensure that last_stmt is always setJosh Stone2010-03-051-30/+45
| | | | | | | | | | | * translate.cxx (c_unparser::record_actions): Take a token to fill in last_stmt for MAXACTION errors. (c_unparser::*): Pass a token to record_actions. (c_unparser::visit_try_block): The try/catch blocks are also basic blocks, so they should flush record_actions when done. (c_unparser_assignment::c_assignop): Set last_stmt for /= and %=. (c_unparser::visit_foreach_loop): Set last_stmt for agg. overflow. (c_unparser::visit_print_format): Set last_stmt for %m errors.
* Make sure synthesized var display is tokenfulJosh Stone2010-03-051-11/+14

* | Improved 'mm_struct' casting for RHEL5.David Smith2010-03-052-11/+11
|/ | | | | | | | * tapset/context.stp: Improved casting to 'mm_struct' on RHEL5 by changing the header file referenced from '<linux/mm_types.h>' to '<linux/sched.h>' (since mm_types.h doesn't exist on RHEL5). On newer kernels, sched.h includes mm_types.h. * tapset/proc_mem.stp: Ditto.

* Add cmdline argument fetching for current process to context.stp tapset.Mark Wielaard2010-03-042-0/+78
| | | | | * tapset/context.stp: Add cmdline_str, cmdline_arg and cmdline_args. * testsuite/buildok/context_test.stp: Add tests for new functions.

* git_version.sh: Don't unnecessarily write to builddir during make install.Mark Wielaard2010-03-031-6/+9
| | | | | | | | | | Ideally make install wouldn't touch the src or build dirs. When the build dir is mounted so root cannot write to it a make install would fail because git_version.sh tried to create a temporary file. Fix by creating temporary git_version.h.new file in temp dir. * git_version.sh: Create temp dir and git_version.h.new outside src and build dir. Change all occurances of $outfile.new to $outfilenew.

(parse_try_block): New function. (lexer ctor): Designate 'try' and 'catch' as keywords. * elaborate.cxx (dead_assignment_remover, dead_statmtexpr_remover): Optimize. (other visitors): Implement. * translate.cxx (c_unparser): Implement via super-handy __local__ labels. (emit_probe, emit_function): Make outer out: label also __local__. * testsuite/buildok/fortyone.stp, semko/fortynine.stp, systemtap.base/trycatch.exp: Test it. * NEWS, doc/langref.txt, stap.1.in: Document it.

| | | | | | | | | | | | | | | | --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 Stone2010-03-027-42/+69
| | | | | | | | | | | 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.

* PR11246: Add more granular cache controlJosh Stone2010-03-024-12/+17
| | | | | | | | | | | | | | 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.
