  • a43783aee   perf tools: Include errno.h where needed ... Browse Code »

    Removing it from util.h, part of an effort to disentangle the includes
    hell, that makes changes to util.h or something included by it to cause
    a complete rebuild of the tools.

  • 5cea57f30   perf tools: Rewrite strbuf not to die() ... Browse Code »

    Rewrite strbuf implementation not to use die() nor xrealloc(). Instead
    of die(), now most of the API returns error code or 0 if succeeded.

  • c71183697   perf tools: Introduce usage_with_options_msg() ... Browse Code »

    Now usage_with_options() setup a pager before printing message so normal
    printf() or pr_err() will not be shown. The usage_with_options_msg()
    can be used to print some help message before usage strings.

    Several areas already used this technique, so do some audit to
    consistently use it elsewhere.

  • f787d9519   perf tools: Fix strbuf_addf() when the buffer needs to grow ... Browse Code »

    This was found during chasing down the header output regression. The
    strbuf_addf() was checking buffer length with a result of vscnprintf()
    which cannot be greater than that of strbuf_avail().

    Since numa topology and pmu mapping info in header were converted to use
    strbuf, it sometimes caused uninteresting behaviors with the broken
    strbuf.

    Fix it by using vsnprintf() which returns desired output string length
    regardless of the available buffer size and grow the buffer if needed.

  • e7f01d1e3   perf tools: Use scnprintf where applicable ... Browse Code »
    86

    Several places were expecting that the value returned was the number of
    characters printed, not what would be printed if there was space.

    Fix it by using the scnprintf and vscnprintf variants we inherited from
    the kernel sources.

    Some corner cases where the number of printed characters were not
    accounted were fixed too.

  • a41794cdd   perf tools: Remove some unused functions ... Browse Code »

    Without the bloated cplus_demangle from binutils, i.e building with:

    $ make NO_DEMANGLE=1 O=~acme/git/build/perf -j3 -C tools/perf/ install

    Before:

    text data bss dec hex filename
    471851 29280 4025056 4526187 45106b /home/acme/bin/perf

    After:

    [acme@doppio linux-2.6-tip]$ size ~/bin/perf
    text data bss dec hex filename
    446886 29232 4008576 4484694 446e56 /home/acme/bin/perf

    So its a 5.3% size reduction in code, but the interesting part is in the git
    diff --stat output:

    19 files changed, 20 insertions(+), 1909 deletions(-)

    If we ever need some of the things we got from git but weren't using, we just
    have to go to the git repo and get fresh, uptodate source code bits.

  • f37a291c5   perf_counter tools: Add more warnings and fix/annotate them ... Browse Code »

    Enable -Wextra. This found a few real bugs plus a number
    of signed/unsigned type mismatches/uncleanlinesses. It
    also required a few annotations

    All things considered it was still worth it so lets try with
    this enabled for now.
