Tests for the fix extension's behavior around non-trivial history topologies.

Looks for correct incremental fixing and reproduction of parent/child

relationships. We indicate fixed file content by uppercasing it.

This tests the only behavior that should really be affected by obsolescence, so
|
|
|
we'll test it with evolution off and on. This only changes the revision
|
|
|
numbers, if all is well.

Setting up the test topology. Scroll down to see the graph produced. We make it
|
|
|
clear which files were modified in each revision. It's enough to test at the
|
|
|
file granularity, because that demonstrates which baserevs were diffed against.
|
|
|
The computation of changed lines is orthogonal and tested separately.

Change C is a root of the set being fixed, so all we fix is what has changed
|
|
|
since its parent. That parent, change B, is its baserev.
|
|
|
|
|
|
$ hg cat -r $C 'set:**'
|
|
|
aaaa
|
|
|
bbbb
|
|
|
CCCC
|
|
|
|
|
|
Change E is a merge with only one parent being fixed. Its baserevs are the
|
|
|
unfixed parent plus the baserevs of the other parent. This evaluates to changes
|
|
|
B and D. We now have to decide what it means to incrementally fix a merge
|
|
|
commit. We choose to fix anything that has changed versus any baserev. Only the
|
|
|
undisturbed content of the common ancestor, change A, is unfixed.
|
|
|
|
|
|
$ hg cat -r $E 'set:**'
|
|
|
aaaa
|
|
|
BBBB
|
|
|
CCCC
|
|
|
DDDD
|
|
|
EEEE
|
|
|
|
|
|
Change H is a merge with neither parent being fixed. This is essentially
|
|
|
equivalent to the previous case because there is still only one baserev for
|
|
|
each parent of the merge.
|
|
|
|
|
|
$ hg cat -r $H 'set:**'
|
|
|
aaaa
|
|
|
FFFF
|
|
|
GGGG
|
|
|
HHHH
|
|
|
|
|
|
Change I is a merge that has four baserevs; two from each parent. We handle
|
|
|
multiple baserevs in the same way regardless of how many came from each parent.
|
|
|
So, fixing change H will fix any files that were not exactly the same in each
|
|
|
baserev.
|
|
|
|
|
|
$ hg cat -r $I 'set:**'
|
|
|
aaaa
|
|
|
BBBB
|
|
|
CCCC
|
|
|
DDDD
|
|
|
EEEE
|
|
|
FFFF
|
|
|
GGGG
|
|
|
HHHH
|
|
|
IIII
|
|
|
|
|
|
Change J is a simple case with one baserev, but its baserev is not its parent,
|
|
|
change C. Its baserev is its grandparent, change B.
|
|
|
|
|
|
$ hg cat -r $J 'set:**'
|
|
|
aaaa
|
|
|
bbbb
|
|

CCCC
|
|
|
JJJJ
|
|
|
|
|
|
The working copy was dirty, so it is treated much like a revision. The baserevs
|
|
|
for the working copy are inherited from its parent, change H, because it is
|
|
|
also being fixed.
|
|
|
|
|
|
$ cat *
|
|
|

GGGG

|
|
|
|
|
|
Change A was never a baserev because none of its children were to be fixed.

$ cd ..

The --all flag should fix anything that wouldn't cause a problem if you fixed
|
|
|
it, including the working copy. Obsolete revisions are not fixed because that
|
|
|
could cause divergence. Public revisions would cause an abort because they are
|
|
|
immutable. We can fix orphans because their successors are still just orphans
|
|
|
of the original obsolete parent. When obsolesence is off, we're just fixing and
|
|
|
replacing anything that isn't public.
