From: Karsten Blees Date: Tue, 01 Jul 2014 22:53:57 GMT Subject: [PATCH v7 00/16] add performance tracing facility Message-ID: <53B33C05.5090900@gmail.com> ...slowly turning into a full-fledged trace overhaul... When working on the documentation, I discovered GIT_TRACE_PACK_ACCESS, which uses a completely separate trace implementation that is 3 times faster by keeping the file open...so this round includes a performance patch that brings the trace API up to speed. Changes since v6: [04-06]: New. [07-08]: Separated the 'disable for test' aspect into a separate patch. GIT_TRACE_BARE=1 is set in test-lib.sh rather than individual tests. Moved static trace_bare variable from global scope into prepare_trace_line(). [09]: Cast timeval.tv_usec to long to prevent compiler warning. [11,13]: Factor out '#define TRACE_CONTEXT __FILE__' so that it can be easily changed to __FUNCTION__. [14]: Added GIT_TRACE_PERFORMANCE to Documentation/git.txt [15-16]: New. [01-03,10,12] are unchanged save resolving conflicts. Karsten Blees (16): trace: move trace declarations from cache.h to new trace.h trace: consistently name the format parameter trace: remove redundant printf format attribute trace: improve trace performance Documentation/git.txt: improve documentation of 'GIT_TRACE*' variables sha1_file: change GIT_TRACE_PACK_ACCESS logging to use trace API trace: add infrastructure to augment trace output with additional info trace: disable additional trace output for unit tests trace: add current timestamp to all trace output trace: move code around, in preparation to file:line output trace: add 'file:line' to all trace output trace: add high resolution timer function to debug performance issues trace: add trace_performance facility to debug performance issues git: add performance tracing for git's main() function to debug scripts wt-status: simplify performance measurement by using getnanotime() progress: simplify performance measurement by using getnanotime() Documentation/git.txt | 59 +++++--- Makefile | 7 + builtin/receive-pack.c | 2 +- cache.h | 13 +- commit.h | 1 + config.mak.uname | 1 + git-compat-util.h | 4 + git.c | 2 + pkt-line.c | 8 +- progress.c | 71 +++++----- sha1_file.c | 30 +--- shallow.c | 10 +- t/test-lib.sh | 4 + trace.c | 369 ++++++++++++++++++++++++++++++++++++++++--------- trace.h | 105 ++++++++++++++ wt-status.c | 14 +- 16 files changed, 524 insertions(+), 176 deletions(-) create mode 100644 trace.h -- 2.0.0.406.ge74f8ff -- -- *** Please reply-to-all at all times *** *** (do not pretend to know who is subscribed and who is not) *** *** Please avoid top-posting. *** The msysGit Wiki is here: https://github.com/msysgit/msysgit/wiki - Github accounts are free.
