18 Arbitraryfilectx.cmp does not follow symlinks: |
|
19 $ mkdir case1 |
|
20 $ cd case1 |
|
21 $ hg init |
|
22 $ printf "A" > real_A |
|
23 $ printf "foo" > A |
|
24 $ printf "foo" > B |
|
25 $ ln -s A sym_A |
|
26 $ hg add . |
|
27 adding A |
|
28 adding B |
|
29 adding real_A |
|
30 adding sym_A |
|
31 $ hg commit -m "base" |
|
32 |
|
33 These files are different and should return True (different): |
|
34 (Note that filecmp.cmp's return semantics are inverted from ours, so we invert |
|
35 for simplicity): |
|
36 $ hg eval "context.arbitraryfilectx('A', repo).cmp(repo[None]['real_A'])" |
|
37 True (no-eol) |
|
38 $ hg eval "not filecmp.cmp('A', 'real_A')" |
|
39 True (no-eol) |
|
40 |
|
41 These files are identical and should return False (same): |
|
42 $ hg eval "context.arbitraryfilectx('A', repo).cmp(repo[None]['A'])" |
|
43 False (no-eol) |
|
44 $ hg eval "context.arbitraryfilectx('A', repo).cmp(repo[None]['B'])" |
|
45 False (no-eol) |
|
46 $ hg eval "not filecmp.cmp('A', 'B')" |
|
47 False (no-eol) |
|
48 |
|
49 This comparison should also return False, since A and sym_A are substantially |
|
50 the same in the eyes of ``filectx.cmp``, which looks at data only. |
|
51 $ hg eval "context.arbitraryfilectx('real_A', repo).cmp(repo[None]['sym_A'])" |
|
52 False (no-eol) |
|
53 |
|
54 A naive use of filecmp on those two would wrongly return True, since it follows |
|
55 the symlink to "A", which has different contents. |
|
56 $ hg eval "not filecmp.cmp('real_A', 'sym_A')" |
|
57 True (no-eol) |
