 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"
 
 Commit preserved largefile contents.
 
   $ cat normal1
   normal11
   $ cat large1
   large11
   $ cat sub/normal2
   normal22
   $ cat sub/large2
   large22
 
 Remove both largefiles and normal files.
  
   $ hg remove normal1 large1
   $ hg commit -m "remove files"
   $ ls
   sub
 
 Copy both largefiles and normal files (testing that status output is correct).
 
   $ hg cp sub/normal2 normal1
   $ hg cp sub/large2 large1
   $ hg st
   A large1
   A normal1
   $ 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

 Commit corner case: specify files to commit.
 
   $ 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
 
 One more commit corner case: commit from a subdirectory.
 
   $ 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
 
 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)

 Corner cases 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 (glob)
   adding sub2/large7 as a largefile (glob)
   $ hg st
   M large3
   A large5
   A sub2/large6
   A sub2/large7
 
 Config settings (pattern **.dat, minsize 2 MB) are respected.
 
   $ echo testdata > test.dat
   $ dd bs=1k count=2k if=/dev/zero of=reallylarge > /dev/null 2> /dev/null
   $ hg add
   adding reallylarge as a largefile
   adding test.dat as a largefile
 
 Test that minsize and --lfsize handle float values;
 also tests that --lfsize overrides largefiles.minsize.
 (0.250 MB = 256 kB = 262144 B)
 
   $ dd if=/dev/zero of=ratherlarge bs=1024 count=256 > /dev/null 2> /dev/null
   $ dd if=/dev/zero of=medium bs=1024 count=128 > /dev/null 2> /dev/null
   $ hg --config largefiles.minsize=.25 add
   adding ratherlarge as a largefile
   adding medium
   $ hg forget medium
   $ hg --config largefiles.minsize=.25 add --lfsize=.125

   $ hg --config largefiles.minsize=.25 add --lfsize=.125

   $ hg forget notlarge
 
 Test forget on largefiles.

 Test status after merging with a branch that introduces a new largefile:
 
   $ echo large > large
   $ hg add --large large
   $ hg commit -m 'add largefile'
   $ hg update -q ".^"
   $ echo change >> normal3
   $ hg commit -m 'some change'
   created new head
   $ hg merge
   1 files updated, 0 files merged, 0 files removed, 0 files unresolved
   (branch merge, don't forget to commit)
   getting changed largefiles
   1 largefiles updated, 0 removed
   $ hg status
   M large
 
 Test that a normal file and a largefile with the same name and path cannot
 coexist.
 
   $ rm sub2/large7
   $ echo "largeasnormal" > sub2/large7
   $ hg add sub2/large7
   sub2/large7 already a largefile
