 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 --cwd foo/bar/baz censor -r $C2 -t "remove password" ../../../target
   $ 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
   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 --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
   Tainted file now super sanitized
   $ hg cat -r $C2 target | head -n 10
   abort: censored node: 1e0247a9a4b7

   $ hg cat -r $C1 target | head -n 10
   abort: censored node: 613bc869fceb
   (set censor.policy to ignore errors)
   $ 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

 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

 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.

   $ C3=$H1
   $ echo 'advanced head H1' > target

   0 files updated, 1 files merged, 0 files removed, 0 files unresolved
   (branch merge, don't forget to commit)

 Can censor after revlog has expanded to no longer permit inline storage

 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)
+   *50002 (re)
   $ hg censor -r $B1 target
   $ hg cat -r $B1 target | wc -l
-  0 (re)
+   *0 (re)
 
 Check the children is fine
 
   $ hg cat -r $B2 target | wc -l
