Improve performance of 'hg felog' command used for indexing of Mercurial repositories

XMLWordPrintable

      In case of large commits (about 40MB of 'hg felog' output), performance of 'hg felog' command (which is a custom plugin for Mercurial, shipped with Fisheye) can be one magnitude slower than built-in 'hg log' + 'hg diff' commands. As a result, repository indexing is slow.

      Example results:

      Script:

      REPO=<repository name>
HASH=<commit hash>
FISHEYE_DIR=<installation dir>

cd $FISHEYE_INST/var/cache/$REPO/clone

for I in {1..10}; do
    echo "Execution #$I"

    echo "Running hg felog ..."
    time /usr/bin/hg --config extensions.felog=$FISHEYE_DIR/python/hg/hgfelog/hgfelog.py --config ui.verbose=false felog $HASH -p -m 1>/dev/null

    echo "Running hg log ..."    
    time hg log -v -r $HASH 1>/dev/null

    echo "Running hg diff ..."
    time hg diff --git -c $HASH 1>/dev/null

done > hg-timings.log 2>&1

      Expected:

      Improve performance of 'felog' to reach speed similar to original Mercurial commands.
