It was generated because a ref change was pushed to the repository containing the project "systemtap: system-wide probe/trace tool". The branch, master has been updated via c87ae2c195e2c0e8d22cdc2c3f767834d605ed90 (commit) via 26e6367359476da839ab1ed7abcc4b52925da649 (commit) from 86229a5533de13b6ac6eeb34d9ea24e7cfb64faa (commit) Those revisions listed above that are new to this repository have not appeared on any other notification email; so we list those revisions in full, below. - Log ----------------------------------------------------------------- commit c87ae2c195e2c0e8d22cdc2c3f767834d605ed90 Author: Josh Stone Date: Fri Oct 1 16:41:19 2010 -0700 Replace kretprobe->entry_ph with a full stap_probe This ensures that pp, pn, and STP_TIMING can be kept distinct for entry handlers vs. their normal kretprobe handlers. * tapsets.cxx (dwarf_derived_probe_group::emit_module_decls): Replace entry_ph with entry_probe, pointing to the global stap_probes[], and update all references. commit 26e6367359476da839ab1ed7abcc4b52925da649 Author: Josh Stone Date: Fri Oct 1 15:47:45 2010 -0700 Centralize stap_probe, and make STP_TIMING data-driven With the move to per-probe_point STP_TIMING statistics, the design which wrote a separate code block for every Stat suddenly ran into scalability issues. We should instead be using a data-driven loop for this. So, the scattered stap_probe structs are now pulled together in one global, stap_probes[]. This contains the usual suspects: ph, pp, and pn; it also keeps the extras that STP_TIMING needs: a Stat, the script location, and the derivation record. * translate.cxx (translate_pass): Add the STP_TIMING data to stap_probe, and output the global stap_probes[] with everything. (c_unparser::emit_module_init): Iterate the timing init at runtime. (c_unparser::emit_module_exit): Iterate the timing output at runtime. * tapsets.cxx (common_probe_init): Just return the right global stap_probe* * tapset*.cxx, runtime/*: Make pointers of all stap_probe's, and make the s/\./->/ change where needed too. * elaborate.cxx (derived_probe::derived_locations): New, gives a string reporting the derivation steps which reached this probe point. ----------------------------------------------------------------------- Summary of changes: elaborate.cxx | 14 +++++- elaborate.h | 5 ++- runtime/perf.h | 2 +- runtime/procfs-probes.c | 8 ++-- runtime/uprobes-common.c | 8 ++-- runtime/uprobes-common.h | 2 +- tapset-been.cxx | 4 +- tapset-itrace.cxx | 4 +- tapset-mark.cxx | 6 +- tapset-perfmon.cxx | 4 +- tapset-procfs.cxx | 10 ++-- tapset-timers.cxx | 25 +++++----- tapset-utrace.cxx | 8 ++-- tapsets.cxx | 89 ++++++++++++++++------------------ translate.cxx | 122 ++++++++++++++++++--------------------------- 15 files changed, 149 insertions(+), 162 deletions(-) hooks/post-receive -- systemtap: system-wide probe/trace tool
