annotate: split functions to get data without applying text formatting

This prepares for porting to generic templater API, where raw data should
be passed to the formatter.

makefunc() is necessary to build closure in list comprehension.

Helper functions:

  $ cacheexists() {
  >   [ -f .hg/cache/tags ] && echo "tag cache exists" || echo "no tag cache"
  > }

  $ dumptags() {
  >     rev=$1
  >     echo "rev $rev: .hgtags:"
  >     hg cat -r$rev .hgtags
  > }

# XXX need to test that the tag cache works when we strip an old head
# and add a new one rooted off non-tip: i.e. node and rev of tip are the
# same, but stuff has changed behind tip.

Setup:

  $ hg init t
  $ cd t
  $ cacheexists
  no tag cache
  $ hg id
  000000000000 tip
  $ cacheexists
  no tag cache
  $ echo a > a
  $ hg add a
  $ hg commit -m "test"
  $ hg co
  0 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ hg identify
  acb14030fe0a tip
  $ cacheexists
  tag cache exists

Try corrupting the cache

  $ printf 'a b' > .hg/cache/tags
  $ hg identify
  .hg/cache/tags is corrupt, rebuilding it
  acb14030fe0a tip
  $ cacheexists
  tag cache exists
  $ hg identify
  acb14030fe0a tip

Create local tag with long name:

  $ T=`hg identify --debug --id`
  $ hg tag -l "This is a local tag with a really long name!"
  $ hg tags
  tip                                0:acb14030fe0a
  This is a local tag with a really long name!     0:acb14030fe0a
  $ rm .hg/localtags

Create a tag behind hg's back:

  $ echo "$T first" > .hgtags
  $ cat .hgtags
  acb14030fe0a21b60322c440ad2d20cf7685a376 first
  $ hg add .hgtags
  $ hg commit -m "add tags"
  $ hg tags
  tip                                1:b9154636be93
  first                              0:acb14030fe0a
  $ hg identify
  b9154636be93 tip

Repeat with cold tag cache:

  $ rm -f .hg/cache/tags
  $ hg identify
  b9154636be93 tip

And again, but now unable to write tag cache:

#if unix-permissions
  $ rm -f .hg/cache/tags
  $ chmod 555 .hg
  $ hg identify
  b9154636be93 tip
  $ chmod 755 .hg
#endif

Create a branch:

  $ echo bb > a
  $ hg status
  M a
  $ hg identify
  b9154636be93+ tip
  $ hg co first
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved
  $ hg id
  acb14030fe0a+ first
  $ hg -v id
  acb14030fe0a+ first
  $ hg status
  M a
  $ echo 1 > b
  $ hg add b
  $ hg commit -m "branch"
  created new head
  $ hg id
  c8edf04160c7 tip

Merge the two heads:

  $ hg merge 1
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  (branch merge, don't forget to commit)
  $ hg id
  c8edf04160c7+b9154636be93+ tip
  $ hg status
  M .hgtags
  $ hg commit -m "merge"

Create a fake head, make sure tag not visible afterwards:

  $ cp .hgtags tags
  $ hg tag last
  $ hg rm .hgtags
  $ hg commit -m "remove"

  $ mv tags .hgtags
  $ hg add .hgtags
  $ hg commit -m "readd"
  $ 
  $ hg tags
  tip                                6:35ff301afafe
  first                              0:acb14030fe0a

Add invalid tags:

  $ echo "spam" >> .hgtags
  $ echo >> .hgtags
  $ echo "foo bar" >> .hgtags
  $ echo "a5a5 invalid" >> .hg/localtags
  $ cat .hgtags
  acb14030fe0a21b60322c440ad2d20cf7685a376 first
  spam
  
  foo bar
  $ hg commit -m "tags"

Report tag parse error on other head:

  $ hg up 3
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ echo 'x y' >> .hgtags
  $ hg commit -m "head"
  created new head

  $ hg tags

  $ hg up -qC 0
  $ hg tag -m 'retag rev 0' -fr 0 bar  # rev 4 bar -> 0, but bar stays at 2

Bar should still point to rev 2:

  bar                                2:6fa450212aeb

Test that removing global/local tags does not get confused when trying
to remove a tag of type X which actually only exists as a type Y:

  adding foo
  $ hg ci -m 'add foo'                 # rev 0

  $ hg tag -r 0 globaltag
  $ hg tag --remove -l globaltag
  abort: tag 'globaltag' is not a local tag
