Merge largefiles into lfs branch
|
|
|
|
|
|
The largefiles extension will prompt to use the normal or largefile when merged
|
|
|
into the lfs files. `hg manifest` will show standins if present. They aren't,
|
|
|
because largefiles merge doesn't merge content. If it did, selecting (n)ormal
|
|
|
would convert to lfs on commit, if appropriate.
|
|
|
|
|
|
BUG: Largefiles isn't running the merge tool, like when two lfs files are
|
|
|
merged. This is probably by design, but it should probably at least prompt if
|
|
|
content should be taken from (l)ocal or (o)ther as well.

When both largefiles and lfs are configured to add by size, the tie goes to
|
|
|
largefiles since it hooks cmdutil.add() and lfs hooks the filelog write in the
|
|
|
commit. By the time the commit occurs, the tracked file is smaller than the
|
|
|
threshold (assuming it is > 41, so the standins don't become lfs objects).

|
|
|
|
|
|
Largefiles doesn't do anything special with diff, so it falls back to diffing
|
|
|
the standins. Extdiff also is standin based comparison. Diff and extdiff both
|
|
|
work on the original file for lfs objects.

A largefiles repo can be converted to lfs. The lfconvert command uses the
|
|
|
convert extension under the hood with --to-normal. So the --config based
|
|
|
parameters are available, but not --authormap, --branchmap, etc.
