* PR10019: --skip-badvars to suppress run-time memory errors tooFrank Ch. Eigler2009-04-011-0/+1
| | | | | | | | * NEWS: Note this change. * hash.cxx (find_script_hash): Add s.skip_badvars into hash. * translate.cxx (translate_pass): Emit STP_SKIP_BADVARS. * runtime/loc2c-runtime.h (DEREF_FAULT, STORE_DEREF_FAULT): Provide dummy implementation if STP_SKIP_BADVARS.
* Skip the git-rev in the hash for now (from a5e8d632)Josh Stone2009-03-261-1/+4
| | | | | | It may be potentially expensive to fork-exec a git call to get the HEAD revision, and it's not clear whether it's even needed. We can always throw this back on if we find a meaningful usage scenario.
* Add the kernel tree's git revision to the hashJosh Stone2009-03-251-0/+4
| | | | | To better support kernel developers who work out of a single source tree, this adds the git HEAD revision to our caching hash.
* Add more file stats to the hashJosh Stone2009-03-251-14/+24
| | | | | | | | | | For kernel developers, it may be common practice to reuse the same kernel build tree for several kernel variants. Our previous hashing only considered the release version, architecture, and build path, which may all remain constant for such a developer. This change adds the file size and mtime of several kernel version files to the hash, so it should be a bit more robust against collisions.
* Cache the tracepoint query resultsJosh Stone2009-03-201-0/+18
| | | | | | | To use tracepoints, we build a "tracequery" module that compiles debuginfo for all available tracepoints in the user's kernel. That's a bit of a cumbersome step to do during pass-2 though. This change adds tracequery caching so we only need to compile it once.
* Clean up the autoconf cachingJosh Stone2009-02-071-1/+2
| | | | | | | | | | | | | | | | | This makes the stapconf caching process quite a bit more transparent. The options are now cached in a header file as #defines, and this header file is a normal build dependency instead of calling so many make $(shell ...) commands. * buildrun.cxx (compile_pass): Pull in autoconf options in a header of #defines rather than -DXXX, and make that header a build dependency. * buildrun.cxx (output_autoconf): New function to consolidate the computation of each autoconf test. * cache.cxx (add_to_cache, get_from_cache, clean_cache): Start treating the stapconf header as a first-class cached item. * cache.h: Move definitions of things only needed in cache.cxx * hash.cxx (find_stapconf_hash): Generate stapconf_name as a .h now. * main.cxx (main): Default the stapconf_name based on getpid().
* Save kernel autoconf options in a cache fileJosh Stone2009-02-061-55/+99
| | | | | | | | | | We're getting enough autoconf tests now that it's a significant chunk of the build time. Adding this cache shaves several seconds off for me. * hash.cxx (find_hash): Compute a separate script-independent hash for caching autoconf values, saved in session.stapconf_path. * buildrun.cxx (compile_pass): Tweak the Makefile to read/save the autoconf values in the cache directory
* Add Vim modelines for GNU style in stapJosh Stone2009-01-281-0/+2

Automatically print written but unread globals Make nodwf test passed when CONFIG_QUOTACTL unset Uses STAPCONF_DPATH_PATH instead of a kernel version check. Simplified "rpm" target a bit. Moved tar archive creation step from "rpm" target to "dist-gzip" target. remove support for "make dist" since git-archive does as well; Examples html files moved into subdir. 2008-08-25 David Smith <dsmith@redhat.com> ChangeLog Entries Robustness improvements for the stap client/server

* PR 4311 - Function boundary tracing without debuginfo: Phase IJim Keniston2008-04-181-0/+15
| | | | | | | | | | | * tapsets.cxx: Major rework of dwflpp, dwarf_query, and related code to make do with elf info if dwarf info is absent, or (in the case of vmlinux) make do with a System.map-style symbol table if even the elf file is absent. * main.cxx: Use getopt_long instead of getopt. Added --kelf, --kmap, --ignore-vmlinux, and --ignore-dwarf. * hash.cxx, session.h, stap.1.in: Added --kelf, --kmap, --ignore-vmlinux, and --ignore-dwarf.
