tags-cache: skip the filternode step if we are not going to use it When warming the hgtagsfnodescache, we don't need the actual result, so we can simply skip the part that "filter" fnode we read from the cache. So provide a quite visible speed up to the top level `hg debugupdatecache` function. ### data-env-vars.name = mozilla-try-2023-03-22-zstd-sparse-revlog # benchmark.name = hg.debug.debug-update-cache # bin-env-vars.hg.flavor = default # bin-env-vars.hg.py-re2-module = default # benchmark.variants.pre-state = warm before: 19.947581 after: 18.916804 (-5.17%, -1.03)

Now d1 is a directory that's both committed and ignored.

    28

Untracked files in d2 are still shown, but ones in d1 are ignored:

  $ touch d1/g

  $ touch d2/g

    32

  $ RAYON_NUM_THREADS=1 hg status
