 Default style is like normal output. Phases style should be the same
 as default style, except for extra phase lines.

   $ hg log --style default > style.out
   $ cmp log.out style.out || diff -u log.out style.out

   $ cmp log.out phases.out || diff -u log.out phases.out
 
 Default style of working-directory revision should also be the same (but
 date may change while running tests):
 
   $ hg log -r 'wdir()' | sed 's|^date:.*|date:|' > log.out
   $ hg log -r 'wdir()' --style default | sed 's|^date:.*|date:|' > style.out

   $ hg log -r 'wdir()' -v --style default | sed 's|^date:.*|date:|' > style.out
   $ cmp log.out style.out || diff -u log.out style.out
 
   $ hg log -r 'wdir()' -q > log.out
   $ hg log -r 'wdir()' -q --style default > style.out
   $ cmp log.out style.out || diff -u log.out style.out
 
   $ hg log -r 'wdir()' --debug | sed 's|^date:.*|date:|' > log.out

   $ cmp log.out style.out || diff -u log.out style.out
 
 Default style should also preserve color information (issue2866):

 Remove commit with empty commit message, so as to not pollute further
 tests.
 
   $ hg --config extensions.strip= strip -q .

 Check that recursive reference does not fall into RuntimeError (issue4758):
 
  common mistake:
 
   $ hg log -T '{changeset}\n'
   abort: recursive reference 'changeset' in template
   [255]
 
  circular reference:
 
   $ cat << EOF > issue4758
   > changeset = '{foo}'
   > foo = '{changeset}'
   > EOF
   $ hg log --style ./issue4758
   abort: recursive reference 'foo' in template
   [255]
 
  buildmap() -> gettemplate(), where no thunk was made:
 
   $ hg log -T '{files % changeset}\n'
   abort: recursive reference 'changeset' in template
   [255]
 
  not a recursion if a keyword of the same name exists:
 
   $ cat << EOF > issue4758
   > changeset = '{tags % rev}'
   > rev = '{rev} {tag}\n'
   > EOF
   $ hg log --style ./issue4758 -r tip

 Check that {phase} works correctly on parents:
 
   $ cat << EOF > parentphase
   > changeset_debug = '{rev} ({phase}):{parents}\n'
   > parent = ' {rev} ({phase})'
   > EOF
   $ hg phase -r 5 --public

   $ hg log --debug -G --style ./parentphase

 Missing non-standard names give no error (backward compatibility):
 
   $ echo "changeset = '{c}'" > t
   $ hg log --style ./t
 
 Defining non-standard name works:
 
   $ cat <<EOF > t
   > changeset = '{c}'
   > c = q
   > EOF

 a revset item must be evaluated as an integer revision, not an offset from tip

 join() should pick '{rev}' from revset items:
 
   $ hg log -R ../a -T '{join(revset("parents(%d)", rev), ", ")}\n' -r6

 on the other hand, parents are formatted as '{rev}:{node|formatnode}' by
 default. join() should agree with the default formatting:

 Templater supports aliases of symbol and func() styles:

 Aliases should be applied only to command arguments and templates in hgrc.
 Otherwise, our stock styles and web templates could be corrupted:
 
   $ hg log -r0 -T '{rn} {utcdate(date)|isodate}\n'
   0:1e4e1b8f71e0 1970-01-12 13:46 +0000

   $ cat <<EOF > tmpl

   > EOF
   $ hg log -r0 --style ./tmpl
   nothing expanded:

   $ hg branches -T '{pad(branch, 7)} {rn}\n'
   default 6:d41e714fe50d
   foo     4:bbe44766e73d
 
 Aliases should honor HGPLAIN:
 
   $ HGPLAIN= hg log -r0 -T 'nothing expanded:{rn}\n'
   nothing expanded:
   $ HGPLAINEXCEPT=templatealias hg log -r0 -T '{rn}\n'
