phabricator: update hgmatcher to cope with the new data format

The new conduit format can't be matched by the existing matcher since it shifts
all the data into an urlencoded string of JSON, the order of which isn't stable
between runs.  Instead detect JSON values of params and load them into python
dicts, which python will then naturally deep-equal compare.

  $ hg init repo
  $ cd repo

add or rename files on top of the master branch

  $ echo a1 > a
  $ echo b1 > b
  $ hg commit -qAm 1
  $ hg bookmark -i main
  $ hg fastannotate --debug -nf b
  fastannotate: b: 1 new changesets in the main branch
  0 b: b1
  $ hg fastannotate --debug -nf a
  fastannotate: a: 1 new changesets in the main branch
  0 a: a1
  $ echo a2 >> a
  $ cat > b << EOF
  > b0
  > b1
  > EOF
  $ hg mv a t
  $ hg mv b a
  $ hg mv t b
  $ hg commit -m 'swap names'

existing linelogs are not helpful with such renames in side branches

  $ hg fastannotate --debug -nf a
  fastannotate: a: linelog cannot help in annotating this revision
  1 a: b0
  0 b: b1
  $ hg fastannotate --debug -nf b
  fastannotate: b: linelog cannot help in annotating this revision
  0 a: a1
  1 b: a2

move main branch forward, rebuild should happen

  $ hg bookmark -i main -r . -q
  $ hg fastannotate --debug -nf b
  fastannotate: b: cache broken and deleted
  fastannotate: b: 2 new changesets in the main branch
  0 a: a1
  1 b: a2
  $ hg fastannotate --debug -nf b
  fastannotate: b: using fast path (resolved fctx: True)
  0 a: a1
  1 b: a2

for rev 0, the existing linelog is still useful for a, but not for b

  $ hg fastannotate --debug -nf a -r 0
  fastannotate: a: using fast path (resolved fctx: True)
  0 a: a1
  $ hg fastannotate --debug -nf b -r 0
  fastannotate: b: linelog cannot help in annotating this revision
  0 b: b1

a rebuild can also be triggered if "the main branch last time" mismatches

  $ echo a3 >> a
  $ hg commit -m a3
  $ cat >> b << EOF
  > b3
  > b4
  > EOF
  $ hg commit -m b4
  $ hg bookmark -i main -q
  $ hg fastannotate --debug -nf a
  fastannotate: a: cache broken and deleted
  fastannotate: a: 3 new changesets in the main branch
  1 a: b0
  0 b: b1
  2 a: a3
  $ hg fastannotate --debug -nf a
  fastannotate: a: using fast path (resolved fctx: True)
  1 a: b0
  0 b: b1
  2 a: a3

linelog can be updated without being helpful

  $ hg mv a t
  $ hg mv b a
  $ hg mv t b
  $ hg commit -m 'swap names again'
  $ hg fastannotate --debug -nf b
  fastannotate: b: 1 new changesets in the main branch
  1 a: b0
  0 b: b1
  2 a: a3
  $ hg fastannotate --debug -nf b
  fastannotate: b: linelog cannot help in annotating this revision
  1 a: b0
  0 b: b1
  2 a: a3

move main branch forward again, rebuilds are one-time

  $ hg bookmark -i main -q
  $ hg fastannotate --debug -nf a
  fastannotate: a: cache broken and deleted
  fastannotate: a: 4 new changesets in the main branch
  0 a: a1
  1 b: a2
  3 b: b3
  3 b: b4
  $ hg fastannotate --debug -nf b
  fastannotate: b: cache broken and deleted
  fastannotate: b: 4 new changesets in the main branch
  1 a: b0
  0 b: b1
  2 a: a3
  $ hg fastannotate --debug -nf a
  fastannotate: a: using fast path (resolved fctx: True)
  0 a: a1
  1 b: a2
  3 b: b3
  3 b: b4
  $ hg fastannotate --debug -nf b
  fastannotate: b: using fast path (resolved fctx: True)
  1 a: b0
  0 b: b1
  2 a: a3

list changeset hashes to improve readability

  $ hg log -T '{rev}:{node}\n'
  4:980e1ab8c516350172928fba95b49ede3b643dca

annotate a revision not in the linelog. linelog cannot be used, but does not get rebuilt either

  $ hg fastannotate --debug -nf a -r 96495c41e4c12218766f78cdf244e768d7718b0f
  fastannotate: a: linelog cannot help in annotating this revision
  1 a: b0
  0 b: b1
  2 a: a3
  $ hg fastannotate --debug -nf a -r 2
  fastannotate: a: linelog cannot help in annotating this revision
  1 a: b0
  0 b: b1
  2 a: a3
  $ hg fastannotate --debug -nf a -r .
  fastannotate: a: using fast path (resolved fctx: True)
  0 a: a1
  1 b: a2
  3 b: b3
  3 b: b4

annotate an ancient revision where the path matches. linelog can be used

  $ hg fastannotate --debug -nf a -r 0
  fastannotate: a: using fast path (resolved fctx: True)
  0 a: a1
  $ hg fastannotate --debug -nf a -r 653e95416ebb5dbcc25bbc7f75568c9e01f7bd2f
  fastannotate: a: using fast path (resolved fctx: False)
  0 a: a1
