Create the repo with a couple of revisions of both large and normal
files (testing that status correctly shows largefiles.

  $ hg init a
  $ cd a
  $ mkdir sub
  $ echo normal1 > normal1
  $ echo normal2 > sub/normal2
  $ echo large1 > large1
  $ echo large2 > sub/large2
  $ hg add normal1 sub/normal2
  $ hg add --large large1 sub/large2
  $ hg commit -m "add files"
  $ echo normal11 > normal1
  $ echo normal22 > sub/normal2
  $ echo large11 > large1
  $ echo large22 > sub/large2
  $ hg st
  M large1
  M normal1
  M sub/large2
  M sub/normal2
  $ hg commit -m "edit files"

Verify that committing new versions of largefiles results in correct
largefile contents, and also that non-largefiles are not affected
badly.

  $ cat normal1
  normal11
  $ cat large1
  large11
  $ cat sub/normal2
  normal22
  $ cat sub/large2
  large22

Verify removing largefiles and normal files works on largefile repos.
 
  $ hg remove normal1 large1
  $ hg commit -m "remove files"
  $ ls
  sub

Test copying largefiles.

  $ hg cp sub/normal2 normal1
  $ hg cp sub/large2 large1
  $ hg commit -m "copy files"
  $ cat normal1
  normal22
  $ cat large1
  large22

Test moving largefiles and verify that normal files are also unaffected.

  $ hg mv normal1 normal3
  $ hg mv large1 large3
  $ hg mv sub/normal2 sub/normal4
  $ hg mv sub/large2 sub/large4
  $ hg commit -m "move files"
  $ cat normal3
  normal22
  $ cat large3
  large22
  $ cat sub/normal4
  normal22
  $ cat sub/large4
  large22

Test archiving the various revisions.  These hit corner cases known with
archiving.

  $ hg archive -r 0 ../archive0
  $ hg archive -r 1 ../archive1
  $ hg archive -r 2 ../archive2
  $ hg archive -r 3 ../archive3
  $ hg archive -r 4 ../archive4
  $ cd ../archive0
  $ cat normal1 
  normal1
  $ cat large1
  large1
  $ cat sub/normal2
  normal2
  $ cat sub/large2
  large2
  $ cd ../archive1
  $ cat normal1
  normal11
  $ cat large1
  large11
  $ cat sub/normal2
  normal22
  $ cat sub/large2
  large22
  $ cd ../archive2
  $ ls
  sub
  $ cat sub/normal2
  normal22
  $ cat sub/large2
  large22
  $ cd ../archive3
  $ cat normal1
  normal22
  $ cat large1
  large22
  $ cat sub/normal2
  normal22
  $ cat sub/large2
  large22
  $ cd ../archive4
  $ cat normal3
  normal22
  $ cat large3
  large22
  $ cat sub/normal4
  normal22
  $ cat sub/large4
  large22

Test a separate commit corner case (specifying files to commit) and check
that the commited files have the right value.

  $ cd ../a
  $ echo normal3 > normal3
  $ echo large3 > large3
  $ echo normal4 > sub/normal4
  $ echo large4 > sub/large4
  $ hg commit normal3 large3 sub/normal4 sub/large4 -m "edit files again"
  $ cat normal3
  normal3
  $ cat large3
  large3
  $ cat sub/normal4
  normal4
  $ cat sub/large4
  large4

Test one more commit corner case that has been known to break (comitting from
a sub-directory of the repo).

  $ cd ../a
  $ echo normal33 > normal3
  $ echo large33 > large3
  $ echo normal44 > sub/normal4
  $ echo large44 > sub/large4
  $ cd sub
  $ hg commit -m "edit files yet again"
  $ cat ../normal3
  normal33
  $ cat ../large3
  large33
  $ cat normal4
  normal44
  $ cat large4
  large44

Check that committing standins is not allowed.

  $ cd ..
  $ echo large3 > large3
  $ hg commit .hglf/large3 -m "try to commit standin"
  abort: file ".hglf/large3" is a largefile standin
  (commit the largefile itself instead)
  [255]

Test some cornercases for adding largefiles.

  $ echo large5 > large5
  $ hg add --large large5
  $ hg add --large large5
  large5 already a largefile
  $ mkdir sub2
  $ echo large6 > sub2/large6
  $ echo large7 > sub2/large7
  $ hg add --large sub2
  adding sub2/large6 as a largefile
  adding sub2/large7 as a largefile
  $ hg st
  M large3
  A large5
  A sub2/large6
  A sub2/large7

Test that files get added as largefiles based on .hgrc settings

  $ echo testdata > test.dat
  $ dd bs=3145728 count=1 if=/dev/zero of=reallylarge > /dev/null 2> /dev/null
  $ hg add
  adding reallylarge as a largefile
  adding test.dat as a largefile
  $ dd bs=1048576 count=1 if=/dev/zero of=reallylarge2 > /dev/null 2> /dev/null

Test that specifying the --lsize command on the comand-line works

  $ hg add --lfsize 1
  adding reallylarge2 as a largefile

Test forget on largefiles.

  $ hg forget large3 large5 test.dat reallylarge reallylarge2
  $ hg st
  A sub2/large6
  A sub2/large7
  R large3
  ? large5
  ? reallylarge
  ? reallylarge2
  ? test.dat
  $ hg commit -m "add/edit more largefiles"
  $ hg st
  ? large3
  ? large5
  ? reallylarge
  ? reallylarge2
  ? test.dat

Test purge with largefiles (verify that largefiles get populated in the
working copy correctly after a purge)

  $ hg purge --all
  $ cat sub/large4
  large44
  $ cat sub2/large6
  large6
  $ cat sub2/large7
