peer: pass the `path` to the statichttp peer

We now have all peer able to receive and store a `path` object. Hooray.

Create repo with unimpeachable content

  $ hg init r
  $ cd r
  $ echo 'Initially untainted file' > target
  $ echo 'Normal file here' > bystander
  $ hg add target bystander
  $ hg ci -m init

Clone repo so we can test pull later

  $ cd ..
  $ hg clone r rpull
  updating to branch default
  2 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ cd r

Introduce content which will ultimately require censorship. Name the first
censored node C1, second C2, and so on

  $ echo 'Tainted file' > target
  $ echo 'Passwords: hunter2' >> target
  $ hg ci -m taint target
  $ C1=`hg id --debug -i`

  $ echo 'hunter3' >> target
  $ echo 'Normal file v2' > bystander
  $ hg ci -m moretaint target bystander
  $ C2=`hg id --debug -i`

Add a new sanitized versions to correct our mistake. Name the first head H1,
the second head H2, and so on

  $ echo 'Tainted file is now sanitized' > target
  $ hg ci -m sanitized target
  $ H1=`hg id --debug -i`

  $ hg update -r $C2
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ echo 'Tainted file now super sanitized' > target
  $ hg ci -m 'super sanitized' target
  created new head
  $ H2=`hg id --debug -i`

Verify target contents before censorship at each revision

  $ hg cat -r $H1 target | head -n 10
  Tainted file is now sanitized
  $ hg cat -r $H2 target | head -n 10
  Tainted file now super sanitized
  $ hg cat -r $C2 target | head -n 10
  Tainted file
  Passwords: hunter2
  hunter3
  $ hg cat -r $C1 target | head -n 10
  Tainted file
  Passwords: hunter2
  $ hg cat -r 0 target | head -n 10
  Initially untainted file

Censor revision with 2 offenses

(this also tests file pattern matching: path relative to cwd case)

  $ mkdir -p foo/bar/baz
  $ hg --config extensions.censor= --cwd foo/bar/baz censor -r $C2 -t "remove password" ../../../target
  $ hg cat -r $H1 target | head -n 10

  $ hg cat -r $H2 target | head -n 10

  $ hg cat -r $C2 target | head -n 10
  abort: censored node: 1e0247a9a4b7
  (set censor.policy to ignore errors)
  $ hg cat -r $C1 target | head -n 10
  Tainted file
  Passwords: hunter2
  $ hg cat -r 0 target | head -n 10
  Initially untainted file

Censor revision with 1 offense

(this also tests file pattern matching: with 'path:' scheme)

  $ hg --config extensions.censor= --cwd foo/bar/baz censor -r $C1 path:target
  $ hg cat -r $H1 target | head -n 10
  Tainted file is now sanitized
  $ hg cat -r $H2 target | head -n 10

  $ hg cat -r $C2 target | head -n 10

  abort: censored node: 613bc869fceb

  $ hg cat -r 0 target | head -n 10

Can only checkout target at uncensored revisions, -X is workaround for --all

  $ hg revert -r $C2 target | head -n 10

  (set censor.policy to ignore errors)

Uncensored file can be viewed at any revision

  $ hg cat -r $H1 bystander | head -n 10
  Normal file v2
  $ hg cat -r $C2 bystander | head -n 10
  Normal file v2
  $ hg cat -r $C1 bystander | head -n 10
  Normal file here
  $ hg cat -r 0 bystander | head -n 10
  Normal file here

Can update to children of censored revision

  $ hg update -r $H1
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ cat target | head -n 10
  Tainted file is now sanitized
  $ hg update -r $H2

Can merge in revision with censored data. Test requires one branch of history
with the file censored, but we can't censor at a head, so advance H1.

  $ hg update -r $H1

  $ C3=$H1
  $ echo 'advanced head H1' > target
  $ hg ci -m 'advance head H1' target

Testing feature that does not work in revlog v1
===============================================

Censoring a revision that is used as delta base
-----------------------------------------------

  $ cd ..
  $ hg init censor-with-delta
  $ cd censor-with-delta
  $ echo root > target
  $ hg add target
  $ hg commit -m root
  $ B0=`hg id --debug -i`
  $ for x in `"$PYTHON" $TESTDIR/seq.py 0 50000`
  > do
  >   echo "Password: hunter$x" >> target
  > done
  $ hg ci -m 'write a long file'
  $ B1=`hg id --debug -i`
  $ echo 'small change (should create a delta)' >> target
  $ hg ci -m 'create a delta over the password'
(should show that the last revision is a delta, not a snapshot)
  $ B2=`hg id --debug -i`

Make sure the last revision is a delta against the revision we will censor

  $ hg debugdeltachain target -T '{rev} {chainid} {chainlen} {prevrev}\n'
  0 1 1 -1
  1 2 1 -1
  2 2 2 1

Censor the file

  $ hg cat -r $B1 target | wc -l
   *50002 (re)
  $ hg --config extensions.censor= censor -r $B1 target
  $ hg cat -r $B1 target | wc -l
   *0 (re)

Check the children is fine

  $ hg cat -r $B2 target | wc -l
   *50003 (re)
