Test update logic when there are renames or weird same-name cases between dirs

and files

Update with local changes across a file rename

  $ hg init r1 && cd r1

  $ echo a > a

  $ hg add a

  $ hg ci -m a

  $ hg mv a b

  $ hg ci -m rename

  $ echo b > b

  $ hg ci -m change

  $ hg up -q 0

  $ echo c > a

  $ hg up

  merging a and b to b

  warning: conflicts while merging b! (edit, then use 'hg resolve --mark')

  0 files updated, 0 files merged, 0 files removed, 1 files unresolved

  use 'hg resolve' to retry unresolved file merges

  [1]

Test update when local untracked directory exists with the same name as a

tracked file in a commit we are updating to

  $ hg init r2 && cd r2

  $ echo root > root && hg ci -Am root  # rev 0

  adding root

  $ echo text > name && hg ci -Am "name is a file"  # rev 1

  adding name

  $ hg up 0

  0 files updated, 0 files merged, 1 files removed, 0 files unresolved

  $ mkdir name

  $ hg up 1

  1 files updated, 0 files merged, 0 files removed, 0 files unresolved

Test update when local untracked directory exists with some files in it and has

the same name a tracked file in a commit we are updating to. In future this

should be updated to give an friendlier error message, but now we should just

make sure that this does not erase untracked data

  $ hg up 0

  0 files updated, 0 files merged, 1 files removed, 0 files unresolved

  $ mkdir name

  $ echo text > name/file

  $ hg st

  ? name/file

  $ hg up 1

  abort: *: '$TESTTMP/r1/r2/name' (glob)

  $ cd ..

#if symlink

Test update when two commits have symlinks that point to different folders

  $ hg init r3 && cd r3

  $ echo root > root && hg ci -Am root

  adding root

  $ mkdir folder1 && mkdir folder2

  $ ln -s folder1 folder

  $ hg ci -Am "symlink to folder1"

  adding folder

  $ rm folder

  $ ln -s folder2 folder

  $ hg ci -Am "symlink to folder2"

  $ hg up 1

  1 files updated, 0 files merged, 0 files removed, 0 files unresolved

  $ cd ..

#endif

#if rmcwd

Test that warning is printed if cwd is deleted during update

  $ hg init r4 && cd r4

  $ mkdir dir

  $ cd dir

  $ echo a > a

  $ echo b > b

  $ hg add a b

  $ hg ci -m "file and dir"

  $ hg up -q null

  current directory was removed

  (consider changing to repo root: $TESTTMP/r1/r4)

#endif

  $ cd $TESTTMP

  $ cat >> $HGRCPATH <<EOF

  > [commands]

  > update.requiredest = True

  > EOF

  $ hg init dest

  $ cd dest

  $ echo a >> a

  $ hg commit -qAm aa

  $ hg up

  abort: you must specify a destination

  (for example: hg update ".::")

  $ hg up .

  0 files updated, 0 files merged, 0 files removed, 0 files unresolved

  $ HGPLAIN=1 hg up

  0 files updated, 0 files merged, 0 files removed, 0 files unresolved
