Setup

  $ setconfig format.dirstate=1
  $ setconfig treestate.mingcage=0
  $ hg init repo
  $ cd repo
  $ echo base > base
  $ hg add base
  $ hg debugdirstate
  a   0         -1 unset               base
  $ hg commit -m "base"
  $ hg debugdirstate

Create path-conflicting dirstates

  $ hg up -q 0
  $ echo a > a
  $ hg add a
  $ hg commit -m a
  $ hg bookmark a
  $ hg up -q 0
  $ mkdir a
  $ echo a/a > a/a
  $ hg add a/a
  $ hg commit -m a/a
  $ hg bookmark a/a
  $ hg up -q a
  $ hg status
  $ hg rm a
  $ hg status
  R a
  $ hg merge --force a/a
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  (branch merge, don't forget to commit)
  $ hg status
  M a/a
  R a
  $ hg rm --force a/a
  $ hg status
  R a
  R a/a
  $ hg up -Cq 0

Attempt to create a path conflict in the manifest

  $ echo b > b
  $ hg add b
  $ hg commit -m b
  $ rm b
  $ mkdir b
  $ echo b/b > b/b
  $ hg add b/b
  abort: file 'b' in dirstate clashes with 'b/b'
  [255]
  $ rm -rf b
  $ hg up -Cq 0

Test warning when creating files that might give a casefold collision

#if no-icasefs
  $ echo data > FiLeNaMe
  $ hg add FiLeNaMe
  $ echo data > FILENAME
  $ hg add FILENAME
  warning: possible case-folding collision for FILENAME
  $ rm -f FiLeNaMe FILENAME
  $ hg up -Cq 0
#endif

Test dirfoldmap and filefoldmap on case insensitive filesystems

#if icasefs
  $ mkdir -p dirA/dirB/dirC
  $ echo file1 > dira/File1
  $ echo file2 > dira/dirb/FILE2
  $ echo file3 > dira/dirb/dirc/FiLe3
  $ echo file4 > dira/dirb/dirc/file4
  $ hg add DIRA
  adding dirA/File1
  adding dirA/dirB/FILE2
  adding dirA/dirB/dirC/FiLe3
  adding dirA/dirB/dirC/file4
  $ hg status
  A dirA/File1
  A dirA/dirB/FILE2
  A dirA/dirB/dirC/FiLe3
  A dirA/dirB/dirC/file4
  $ hg forget dira/DIRB
  removing dirA/dirB/FILE2
  removing dirA/dirB/dirC/FiLe3
  removing dirA/dirB/dirC/file4
  $ hg status
  A dirA/File1
  ? dirA/dirB/FILE2
  ? dirA/dirB/dirC/FiLe3
  ? dirA/dirB/dirC/file4
  $ hg add dira/dirb/file2
  $ hg status

  A dirA/dirB/FILE2

  $ rm -rf dirA
#endif

Test autorepack

  $ ls .hg/dirstate.tree.*
  .hg/dirstate.tree.* (glob)
  $ echo data > file

After the first repack, the old trees are kept around by the transaction undo backups.
  $ hg add file --config treestate.minrepackthreshold=1 --config treestate.repackfactor=0 --debug | grep -v 'in use by'
  adding file
  auto-repacking treedirstate
  $ ls .hg/dirstate.tree.*
  .hg/dirstate.tree.* (glob)
  .hg/dirstate.tree.* (glob)

After the second repack, the old trees are still kept around.
  $ hg forget file --config treestate.minrepackthreshold=1 --config treestate.repackfactor=0 --debug | grep -v 'in use by'
  fsmonitor: fallback to core status, full rewalk requested (fsmonitor !)

  $ ls .hg/dirstate.tree.*
  .hg/dirstate.tree.* (glob)
  .hg/dirstate.tree.* (glob)
  .hg/dirstate.tree.* (glob)

On the third repack, the original tree is removed.
  $ hg add file --config treestate.minrepackthreshold=1 --config treestate.repackfactor=0 --debug | grep -v 'in use by'
  adding file
  auto-repacking treedirstate

  $ ls .hg/dirstate.tree.*
  .hg/dirstate.tree.* (glob)
  .hg/dirstate.tree.* (glob)
  .hg/dirstate.tree.* (glob)

On the fourth repack, the second tree is removed.
  $ hg forget file --config treestate.minrepackthreshold=1 --config treestate.repackfactor=0 --debug | grep -v 'in use by'
  fsmonitor: fallback to core status, full rewalk requested (fsmonitor !)

Test downgrade on pull

  $ for f in 1 2 3 4 5 ; do mkdir dir$f ; echo $f > dir$f/file$f ; hg add dir$f/file$f ; done
  $ echo x > a

  $ hg commit -m "add files"

Test upgrade on pull

  $ hg pull --config treestate.migrateonpull=true --config format.dirstate=1
  please wait while we migrate dirstate format to version 1
  this will make your hg commands faster...
