rust: add Debug constraint to Matcher trait

This makes sure we can easily debug which Matcher we're looking at when using
trait objects, and is just generally useful. Effort to make the debugging
output nicer has been kept to a minimum, please feel free to improve.

===============================
Test the "tracked hint" feature
===============================

The tracked hint feature provide a file that get updated when the set of tracked
files get updated.

basic setup

  $ cat << EOF >> $HGRCPATH
  > [format]
  > use-dirstate-tracked-hint=yes
  > EOF

  $ hg init tracked-hint-test
  $ cd tracked-hint-test
  $ hg debugbuilddag '.+10' -n
  $ hg log -G -T '{rev} {desc} {files}\n'
  o  10 r10 nf10
  |
  o  9 r9 nf9
  |
  o  8 r8 nf8
  |
  o  7 r7 nf7
  |
  o  6 r6 nf6
  |
  o  5 r5 nf5
  |
  o  4 r4 nf4
  |
  o  3 r3 nf3
  |
  o  2 r2 nf2
  |
  o  1 r1 nf1
  |
  o  0 r0 nf0
  
  $ hg up tip
  11 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ hg files
  nf0
  nf1
  nf10
  nf2
  nf3
  nf4
  nf5
  nf6
  nf7
  nf8
  nf9

key-file exists
-----------

The tracked hint file should exist

  $ ls -1 .hg/dirstate*
  .hg/dirstate
  .hg/dirstate-tracked-hint

key-file stay the same if the tracked set is unchanged
------------------------------------------------------

(copy its content for later comparison)

  $ cp .hg/dirstate-tracked-hint ../key-bck
  $ echo foo >> nf0
  $ sleep 1
  $ hg status
  M nf0
  $ diff --brief .hg/dirstate-tracked-hint ../key-bck
  $ hg revert -C nf0
  $ sleep 1
  $ hg status
  $ diff --brief .hg/dirstate-tracked-hint ../key-bck

key-file change if the tracked set is changed manually
------------------------------------------------------

adding a file to tracking

  $ cp .hg/dirstate-tracked-hint ../key-bck
  $ echo x > x
  $ hg add x
  $ diff --brief .hg/dirstate-tracked-hint ../key-bck
  Files .hg/dirstate-tracked-hint and ../key-bck differ
  [1]

remove a file from tracking
(forget)

  $ cp .hg/dirstate-tracked-hint ../key-bck
  $ hg forget x
  $ diff --brief .hg/dirstate-tracked-hint ../key-bck
  Files .hg/dirstate-tracked-hint and ../key-bck differ
  [1]

(remove)

  $ cp .hg/dirstate-tracked-hint ../key-bck
  $ hg remove nf1
  $ diff --brief .hg/dirstate-tracked-hint ../key-bck
  Files .hg/dirstate-tracked-hint and ../key-bck differ
  [1]

key-file changes on revert (when applicable)
--------------------------------------------

  $ cp .hg/dirstate-tracked-hint ../key-bck
  $ hg status
  R nf1
  ? x
  $ hg revert --all
  undeleting nf1
  $ hg status
  ? x
  $ diff --brief .hg/dirstate-tracked-hint ../key-bck
  Files .hg/dirstate-tracked-hint and ../key-bck differ
  [1]


`hg update` does affect the key-file (when needed)
--------------------------------------------------

update changing the tracked set

(removing)

  $ cp .hg/dirstate-tracked-hint ../key-bck
  $ hg status --rev . --rev '.#generations[-1]'
  R nf10
  $ hg up '.#generations[-1]'
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved
  $ diff --brief .hg/dirstate-tracked-hint ../key-bck
  Files .hg/dirstate-tracked-hint and ../key-bck differ
  [1]

(adding)

  $ cp .hg/dirstate-tracked-hint ../key-bck
  $ hg status --rev . --rev '.#generations[1]'
  A nf10
  $ hg up '.#generations[1]'
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ diff --brief .hg/dirstate-tracked-hint ../key-bck
  Files .hg/dirstate-tracked-hint and ../key-bck differ
  [1]

update not affecting the tracked set

  $ echo foo >> nf0
  $ hg commit -m foo

  $ cp .hg/dirstate-tracked-hint ../key-bck
  $ hg status --rev . --rev '.#generations[-1]'
  M nf0
  $ hg up '.#generations[-1]'
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ diff --brief .hg/dirstate-tracked-hint ../key-bck

Test upgrade and downgrade
==========================

  $ ls .hg/dirstate-tracked-hint
  .hg/dirstate-tracked-hint
  $ hg debugrequires | grep 'tracked'
  dirstate-tracked-key-v1

downgrade

  $ hg debugupgraderepo --config format.use-dirstate-tracked-hint=no --run --quiet
  upgrade will perform the following actions:
  
  requirements
     preserved: * (glob)
     removed: dirstate-tracked-key-v1
  
  no revlogs to process
  
  $ ls -1 .hg/dirstate-tracked-hint
  ls: *.hg/dirstate-tracked-hint*: $ENOENT$ (glob)
  [2]
  $ hg debugrequires | grep 'tracked'
  [1]

upgrade

  $ hg debugupgraderepo --config format.use-dirstate-tracked-hint=yes --run --quiet
  upgrade will perform the following actions:
  
  requirements
     preserved: * (glob)
     added: dirstate-tracked-key-v1
  
  no revlogs to process
  
  $ ls -1 .hg/dirstate-tracked-hint
  .hg/dirstate-tracked-hint
  $ hg debugrequires | grep 'tracked'
  dirstate-tracked-key-v1
  $ cd ..

Test automatic upgrade and downgrade
------------------------------------

create an initial repository

  $ hg init auto-upgrade \
  > --config format.use-dirstate-tracked-hint=no
  $ hg debugbuilddag -R auto-upgrade --new-file .+5
  $ hg -R auto-upgrade update
  6 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ hg debugformat -R auto-upgrade | grep tracked
  tracked-hint:        no

upgrade it to dirstate-tracked-hint automatically

  $ hg status -R auto-upgrade \
  > --config format.use-dirstate-tracked-hint.automatic-upgrade-of-mismatching-repositories=yes \
  > --config format.use-dirstate-tracked-hint=yes
  automatically upgrading repository to the `tracked-hint` feature
  (see `hg help config.format.use-dirstate-tracked-hint` for details)
  $ hg debugformat -R auto-upgrade | grep tracked
  tracked-hint:       yes

downgrade it from dirstate-tracked-hint automatically

  $ hg status -R auto-upgrade \
  > --config format.use-dirstate-tracked-hint.automatic-upgrade-of-mismatching-repositories=yes \
  > --config format.use-dirstate-tracked-hint=no
  automatically downgrading repository from the `tracked-hint` feature
  (see `hg help config.format.use-dirstate-tracked-hint` for details)
  $ hg debugformat -R auto-upgrade | grep tracked
  tracked-hint:        no
