Since Mozc was updated to 2.29.5160.102, we keep that version until now. Now we have bazel 7.7.1 on unstable, we have a chance to upgrade Mozc to 3.33.6133.
Info
The following slide presents "How to upgrading to newer Mozc on unstable". If we need newer Mozc on Debian 14 (forky), it is a good chance to working on it.
Patch
Upgrading from Mozc 2.29.5160.102 to Mozc 3.33.6133 is very challenging approach because there are many changes through 2.30.x, 2.31.x, 2.32.x and 3.33.x.
Most notable change is switching from GYP to Bazel.
Additionally, there are many src/third_party bundles to resolve dependency for our offline build process. As a result, we need to handle large patches to do it.
Typically, 0012-Add-zip-code-data.patch (15MB) is the most large patch file to do zip code conversion.
Thus the outcome of debdiff is also large to attach Debian BTS.
