Test bug regarding symlinks that showed up in hg 0.7

Author: Matthew Elder <sseses@gmail.com>

  $ "$TESTDIR/hghave" symlink || exit 80

make and initialize repo

  $ hg init test; cd test;

make a file and a symlink

  $ touch foo; ln -s foo bar;

import with addremove -- symlink walking should _not_ screwup.

  $ hg addremove

  adding bar

  adding foo

commit -- the symlink should _not_ appear added to dir state

  $ hg commit -m 'initial'

add a new file so hg will let me commit again

  $ touch bomb

again, symlink should _not_ show up on dir state

  $ hg addremove

  adding bomb

Assert screamed here before, should go by without consequence

  $ hg commit -m 'is there a bug?'

  $ cd .. ; rm -r test

  $ hg init test; cd test;

  $ mkdir dir

  $ touch a.c dir/a.o dir/b.o

test what happens if we want to trick hg

  $ hg commit -A -m 0

  adding a.c

  adding dir/a.o

  adding dir/b.o

  $ echo "relglob:*.o" > .hgignore

  $ rm a.c

  $ rm dir/a.o

  $ rm dir/b.o

  $ mkdir dir/a.o

  $ ln -s nonexist dir/b.o

  $ mkfifo a.c

it should show a.c, dir/a.o and dir/b.o deleted

  $ hg status

  M dir/b.o

  ! a.c

  ! dir/a.o

  ? .hgignore

  $ hg status a.c

  a.c: unsupported file type (type is fifo)

  ! a.c

test absolute path through symlink outside repo

  $ cd ..

  $ p=`pwd`

  $ hg init x

  $ ln -s x y

  $ cd x

  $ touch f

  $ hg add f

  $ hg status "$p"/y/f

  A f

try symlink outside repo to file inside

  $ ln -s x/f ../z

this should fail

  $ hg status ../z && { echo hg mistakenly exited with status 0; exit 1; } || :

  abort: ../z not under root

  $ cd .. ; rm -r test

  $ hg init test; cd test;

try cloning symlink in a subdir

1. commit a symlink

  $ mkdir -p a/b/c

  $ cd a/b/c

  $ ln -s /path/to/symlink/source demo

  $ cd ../../..

  $ hg stat

  ? a/b/c/demo

  $ hg commit -A -m 'add symlink in a/b/c subdir'

  adding a/b/c/demo

2. clone it

  $ cd ..

  $ hg clone test testclone

  updating to branch default

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

git symlink diff

  $ cd testclone

  $ hg diff --git -r null:tip
