* 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

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.

Changes also by Martin Hunt <hunt@redhat.com>. * Makefile.am: Added staprun_funcs.c and cap.c to staprun_SOURCES. Added -lcap to staprun_LDADD. Removed stp_check reference. Added stapio program. Staprun is now setuid. * Makefile.in: Rebuilt. * configure.ac: Version increase to 0.6 and checks for libcap availability. Removed stp_check reference. * configure: Regenerated. * stp_check.in: Removed. * systemtap.spec.in: Version increase to 0.6-1 and added BuildReq for libcap-devl (and removed sudo requirement). Added %pre script to create new groups. Staprun is now setuid. * NEWS: Added info on new security model. * INTERNALS: Removed sudo reference. * README.security: New file. * main.cxx (main): Make sure module name isn't too long. * hash.cxx: Moved MODULE_NAME_LEN define to hash.h. * hash.h: Moved MODULE_NAME_LEN define here from hash.cxx. * buildrun.cxx (run_pass): No longer runs staprun with "sudo". * stap.1.in: Removed sudo references and added information about the stapdev/stapusr groups. * staprun.8.in: Added information about module detaching and attaching. Removed sudo references and added information about the stapdev/stapusr groups. Removed reference to staprun needing to be run as root. Removed reference to removed '-u USERNAME' option. * .cvsignore: Removed stp_check and added stapio and stap_merge.

Initialize based on autoconf flag. * stap.1.in, NEWS: Document it. * hash.cxx (find_hash): Include it in computation. * tapsets.cxx (query_func_info, query_cu): Respect it. 2007-02-09 Frank Ch.

| | | | | | * hash.cxx (find_hash): Added two more options into the hash that change the generated C file - '-M' (merge) and '-t' (benchmark timing).

| | | | | | * hash.cxx (find_hash): Fixed a caching bug. Bulk mode (relayfs) status should be figured into the hash since it changes the generated C code.
* 2006-10-23 David Smith <dsmith@redhat.com>dsmith2006-10-231-0/+168
* main.cxx (printscript): New function containing code moved from main(). (main): Added code to create cache directory, call function to generate hash, and see if we can use cached source/module. If pass 4 is actually run to produce a new module, we call add_to_cache() to cache the result. * session.h (struct systemtap_session): Added hash/cache session data. * cache.cxx: New file handling adding/getting files from the cache. * cache.h: New header file for cache.cxx. * hash.cxx: New file containing C++ wrapper for routines in mdfour.c and the find_hash function which computes the hash file name for an input script. * hash.h: New header file for hash.cxx. * mdfour.c: New file containing MD4 hash code. * mdfour.h: New header file for mdfour.c. * util.cxx: New file containing several utility functions used by the caching code. * util.h: New header file for util.cxx. * Makefile.am: Added new C/C++ files. * Makefile.in: Regenerated.
