 """style and portability checker for Mercurial
 
 when a rule triggers wrong, do one of the following (prefer one from top):
  * do the work-around the rule suggests
  * doublecheck that it is a false match
  * improve the rule pattern
  * add an ignore pattern to the rule (3rd arg) which matches your good line
    (you can append a short comment and match this, like: #re-raises, # no-py24)
  * change the pattern to a warning and list the exception in test-check-code-hg
  * ONLY use no--check-code for skipping entire files from external sources

 Systematic testing of merges involving largefiles:
 
 Ancestor: normal  Parent: normal=  Parent: large   result: large
 Ancestor: normal  Parent: normal2  Parent: large   result: ?
 Ancestor: large   Parent: large=   Parent: normal  result: normal
 Ancestor: large   Parent: large2   Parent: normal  result: ?
 
 All cases should try merging both ways.
 "=" means same file content.
 
 Prepare test repo:
 
   $ hg init merges
   $ cd merges
   $ touch f1
   $ hg ci -Aqm "0-root" --config extensions.largefiles=!
 
 Ensure that .hg/largefiles isn't created before largefiles are added
 #if unix-permissions
   $ chmod 555 .hg

   $ hg status
 #if unix-permissions
   $ chmod 755 .hg

 Modify one of the externals to point to a different path so we can

   $ echo "obstruct =        [svn]       $SVNREPOURL/externals" >> .hgsub

   $ svn co -r5 --quiet "$SVNREPOURL"/src obstruct
   $ hg commit -m 'Other branch which will be obstructed'
   created new head
 
 Switching back to the head where we have another path mapped to the
 same subrepo should work if the subrepo is clean.
   $ hg co other

   Checked out revision 1.
   2 files updated, 0 files merged, 0 files removed, 0 files unresolved

 This is surprising, but is also correct based on the current code:
   $ echo "updating should (maybe) fail" > obstruct/other
   $ hg co tip
   abort: uncommitted changes
   (commit or update --clean to discard changes)
   [255]
 
 Point to a Subversion branch which has since been deleted and recreated
 First, create that condition in the repository.
