This removes ambiguity as to which modules are being imported, making
import slightly faster as Python doesn't need to test so many
directories for file presence.
All files should already be using absolute imports because mach command
modules aren't imported to the package they belong to: they instead
belong to the "mach" package. So relative imports shouldn't have been
used.
Back when mozpack.path was added, it was used as:
import mozpack.path
mozpack.path.func()
Nowadays, the common idiom is:
import mozpack.path as mozpath
mozpath.func()
because it's shorter.
$ git grep mozpath\\. | wc -l
423
$ git grep mozpack.path\\. | wc -l
123
This change was done with:
$ git grep -l mozpack.path\\. | xargs sed -i 's/mozpack\.path\./mozpath./g'
$ git grep -l 'import mozpack.path$' | xargs sed -i 's/import mozpack.path$/\0 as mozpath/'
$ (pat='import mozpack.path as mozpath'; git grep -l "$pat" | xargs sed -i "1,/$pat/b;/$pat/d")
We're using as many defaults from the configure step as we can. We're also opinionated upon the defaults, but obviously allow most compare-locales options to be specified.
There are two exceptions:
Reference language is specified to be en-US, without optional argument. This is our in-tree command, and the reference language is known.
We always clobber the merge dir, and don't give an option not to. We default to a merge dir in the objdir, so we don't need to be that paranoid as in the standalone version.
Also, compare-locales clobbers merge-dir/browser etc, so you're not going to get / removed.
