stream-clone: disable gc for the entry listing section for the v2 format This is similar to the change we did for the v3 format in 6e4c8366c5ce. The benchmark bellow show this gives us a notable gains, especially on larger repositories. ### benchmark.name = hg.perf.stream-locked-section # benchmark.name = hg.perf.stream-locked-section # bin-env-vars.hg.flavor = default # bin-env-vars.hg.py-re2-module = default # benchmark.variants.version = v2 ## data-env-vars.name = pypy-2018-08-01-zstd-sparse-revlog 5e931bf8707c: 0.503820 ~~~~~ 1106d1bf695e: 0.470078 (-6.70%, -0.03) ## data-env-vars.name = pypy-2024-03-22-zstd-sparse-revlog 5e931bf8707c: 0.535756 ~~~~~ 1106d1bf695e: 0.490249 (-8.49%, -0.05) ## data-env-vars.name = heptapod-public-2024-03-25-zstd-sparse-revlog 5e931bf8707c: 1.327041 ~~~~~ 1106d1bf695e: 1.174636 (-11.48%, -0.15) ## data-env-vars.name = netbeans-2018-08-01-zstd-sparse-revlog 5e931bf8707c: 2.439158 ~~~~~ 1106d1bf695e: 2.220515 (-8.96%, -0.22) ## data-env-vars.name = netbeans-2019-11-07-zstd-sparse-revlog 5e931bf8707c: 2.630794 ~~~~~ 1106d1bf695e: 2.261473 (-14.04%, -0.37) ## data-env-vars.name = mozilla-central-2018-08-01-zstd-sparse-revlog 5e931bf8707c: 5.769002 ~~~~~ 1106d1bf695e: 5.062000 (-12.26%, -0.71) ## data-env-vars.name = mozilla-try-2019-02-18-zstd-sparse-revlog 5e931bf8707c: 13.351750 ~~~~~ 1106d1bf695e: 12.346655 (-7.53%, -1.01) ## data-env-vars.name = mozilla-central-2024-03-22-zstd-sparse-revlog 5e931bf8707c: 10.772939 ~~~~~ 1106d1bf695e: 9.495407 (-11.86%, -1.28) ## data-env-vars.name = mozilla-unified-2024-03-22-zstd-sparse-revlog 5e931bf8707c: 10.864297 ~~~~~ 1106d1bf695e: 9.475597 (-12.78%, -1.39) ## data-env-vars.name = mozilla-try-2023-03-22-zstd-sparse-revlog 5e931bf8707c: 17.448335 ~~~~~ 1106d1bf695e: 16.027474 (-8.14%, -1.42)

  $ hg init repo
  $ cd repo
  $ echo foo > a
  $ hg add a
  $ hg commit -m "1"

  $ echo bar > b
  $ hg add b
  $ hg remove a

Should show a removed and b added:

  $ hg status
  A b
  R a

  $ hg revert --all
  forgetting b
  undeleting a

Should show b unknown and a back to normal:

  $ hg status
  ? b

  $ rm b

  $ hg co -C 0
  0 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ echo foo-a > a
  $ hg commit -m "2a"

  $ hg co -C 0
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ echo foo-b > a
  $ hg commit -m "2b"
  created new head

  $ HGMERGE=true hg merge 1
  merging a
  0 files updated, 1 files merged, 0 files removed, 0 files unresolved
  (branch merge, don't forget to commit)

Should show foo-b:

  $ cat a
  foo-b

  $ echo bar > b
  $ hg add b
  $ rm a
  $ hg remove a

Should show a removed and b added:

  $ hg status
  A b
  R a

Revert should fail:

  $ hg revert
  abort: uncommitted merge with no revision specified
  (use 'hg update' or see 'hg help revert')
  [10]

Revert should be ok now:

  $ hg revert -r2 --all
  forgetting b
  undeleting a

Should show b unknown and a marked modified (merged):

  $ hg status
  M a
  ? b

Should show foo-b:

  $ cat a
  foo-b
