Systematic testing of merges involving largefiles:
Ancestor: normal Parent: normal= Parent: large result: large
Ancestor: normal Parent: normal2 Parent: large result: ?
Ancestor: large Parent: large= Parent: normal result: normal
Ancestor: large Parent: large2 Parent: normal result: ?
All cases should try merging both ways.
"=" means same file content.
Prepare test repo:
$ hg init merges
$ cd merges
$ touch f1
$ hg ci -Aqm "0-root" --config extensions.largefiles=!
Ensure that .hg/largefiles isn't created before largefiles are added
#if unix-permissions
$ chmod 555 .hg
