1498533 - Add serialization to compare-locales, based on cross-channel merge

Status: RESOLVED FIXED

(Localization Infrastructure and Tools :: compare-locales, enhancement)

Description

[Axel Hecht [:Pike]]

Cross-channel merge code is useful for serialization of cross-channel, fluent.migrate, fluent.migrate --force, pontoon, and l10n-merge. We’ll need a dead or placeholder entity for the ones that we don’t want to change. That assists the ordering algorithm, but will need to be stripped in prune() to collapse adjacent white-space.

For --force, l10n-merge, and pontoon, we’ll need to reverse the order in which we’re keeping duplicate entries.
For pontoon and l10n-merge we’ll also need an optional filter that strips “bad” messages.

Attachment: bug 1498533, add serialization support, r=stas

This adds an option to merge_channels to keep the oldest
instead of the newest variant, and uses that to serialize a file.

The file structure is taken from the en-US template.

This only supports Fluent, Android's string.xml and .properties.
Other file formats supported by compare-locales might work,
but will be added later (and get tests added).

This comes as two changesets, the first of which is just
technical and doesn't really require review.
It's requiring a follow-up change in cross-channel, so I
don't want to just land that.

Landed as https://hg.mozilla.org/l10n/compare-locales/rev/17b6b3bc231c18006f052c081889a06bc1c875a6.

It'd be nice if we could dogfood the code from pontoon a bit before I release 5.0.3 ;-)
