perf-stream-consume: use the source repository config when applying This might contains critical configuration for the benchmark, like enabling of extensions like narrow.

Force revlog max inline value to be smaller than default

  $ mkdir $TESTTMP/ext
  $ cat << EOF > $TESTTMP/ext/small_inline.py
  > from mercurial import revlog
  > revlog._maxinline = 8
  > EOF

  $ cat << EOF >> $HGRCPATH
  > [extensions]
  > small_inline=$TESTTMP/ext/small_inline.py
  > EOF

  $ hg init repo
  $ cd repo

Try on an empty repository

  $ hg debug-revlog-stats
  rev-count   data-size inl type      target 

  $ mkdir folder
  $ touch a b folder/c folder/d
  $ hg commit -Aqm 0
  $ echo "text" > a
  $ hg rm b
  $ echo "longer string" > folder/d
  $ hg commit -Aqm 1

Differences in data size observed with pure is due to different compression
algorithms

  $ hg debug-revlog-stats

          2         138 no  changelog  (no-pure !)

          2          15 no  file      folder/d

Test 'changelog' command argument

          2         137 no  changelog  (pure !)

Test 'manifest' command argument

  $ hg debug-revlog-stats -m
  rev-count   data-size inl type      target

          2         168 no  manifest   (pure !)

Test 'file' command argument

  $ hg debug-revlog-stats -f
  rev-count   data-size inl type      target 
          2           6 yes file      a

          2          15 no  file      folder/d

Test multiple command arguments

  $ hg debug-revlog-stats -cm
