Reverting copy (issue3920)
--------------------------

someone set up us the copies

  $ rm .hgignore
  $ hg update -C
  0 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ hg mv ignored allyour
  $ hg copy removed base
  $ hg commit -m rename

copies and renames, you have no chance to survive make your time (issue3920)

  $ hg update '.^'
  1 files updated, 0 files merged, 2 files removed, 0 files unresolved
  $ hg revert -rtip -a
  adding allyour
  adding base
  removing ignored
  $ hg status -C
  A allyour
    ignored
  A base
    removed
  R ignored

Test revert of a file added by one side of the merge
====================================================

remove any pending change

  $ hg revert --all
  forgetting allyour
  forgetting base
  undeleting ignored
  $ hg purge --all --config extensions.purge=

Adds a new commit

  $ echo foo > newadd
  $ hg add newadd
  $ hg commit -m 'other adds'
  created new head


merge it with the other head

  $ hg merge # merge 1 into 2
  2 files updated, 0 files merged, 1 files removed, 0 files unresolved
  (branch merge, don't forget to commit)
  $ hg summary
  parent: 2:b8ec310b2d4e tip
   other adds
  parent: 1:f6180deb8fbe 
   rename
  branch: default
  commit: 2 modified, 1 removed (merge)
  update: (current)

clarifies who added what

  $ hg status
  M allyour
  M base
  R ignored
  $ hg status --change 'p1()'
  A newadd
  $ hg status --change 'p2()'
  A allyour
  A base
  R ignored

revert file added by p1() to p1() state
-----------------------------------------

  $ hg revert -r 'p1()' 'glob:newad?'
  $ hg status
  M allyour
  M base
  R ignored

revert file added by p1() to p2() state
------------------------------------------

  $ hg revert -r 'p2()' 'glob:newad?'
  removing newadd
  $ hg status

------------------------------------------

  $ hg revert -r 'p2()' 'glob:allyou?'
  $ hg status
  M allyour
  M base
  R ignored
  R newadd

revert file added by p2() to p1() state
------------------------------------------

  $ hg revert -r 'p1()' 'glob:allyou?'
  removing allyour
  $ hg status
  M base
  R allyour
  R ignored
  R newadd

Systematic behavior validation of most possible cases
=====================================================

This section tests most of the possible combinations of revision states and
working directory states. The number of possible cases is significant but they
but they all have a slightly different handling. So this section commits to
and testing all of them to allow safe refactoring of the revert code.

A python script is used to generate a file history for each combination of
states, on one side the content (or lack thereof) in two revisions, and
on the other side, the content and "tracked-ness" of the working directory. The
three states generated are:

- a "base" revision
- a "parent" revision
- the working directory (based on "parent")

The files generated have names of the form:

 <rev1-content>_<rev2-content>_<working-copy-content>-<tracked-ness>

All known states are not tested yet. See inline documentation for details.
Special cases from merge and rename are not tested by this section.

Write the python script to disk
-------------------------------

Script to make a simple text version of the content
---------------------------------------------------

  $ cat << EOF >> dircontent.py
  > # generate a simple text view of the directory for easy comparison
  > import os
  > files = os.listdir('.')
  > files.sort()
  > for filename in files:
  >     if os.path.isdir(filename):
  >         continue
  >     content = open(filename).read()
  >     print '%-6s %s' % (content.strip(), filename)
  > EOF

check resulting directory against the --all run

Test revert to "base" content with explicit file name
-----------------------------------------------------

(setup from reference repo)

  $ cp -r revert-ref revert-base-explicit
  $ cd revert-base-explicit

revert all files individually and check the output
(output is expected to be different than in the --all case)

  $ for file in `python $TESTDIR/generate-working-copy-states.py filelist 2`; do
  >   echo '### revert for:' $file;
  >   hg revert $file --rev 'desc(base)';
  >   echo
  > done
