Source: mozc
Version: 2.28.4715.102+dfsg-2.3
Severity: normal
X-Debbugs-Cc: ***@xdump.org

Dear Maintainer,

The upstream repository has released 2.30.5544.102.

It would be nice to upgrade the Debian package to that release.

But currently, there are technical difficulty exists to following
upstream releases in some cases.

* GYP was deprecated
* Instead, newer Bazel is required to build it, but not exist on
Debian yet.
* Only old Bazel is available on Debian
* bazel-bootstrap stick to 4.x, need to update Bazel 7.x (maybe)
* Newer version of Abseil is required
* Mozc 2.30.5544.102 requires Abseil 20240116.1 or newer one.

As a practical approach, it is reasonable to update existing GYP patch
to refactor for newer mozc version which targets at max 2.29.5544.102.

Here is the brief review of current patches.

* 0001-Update-uim-mozc-to-c979f127acaeb7b35d3344e8b1e40848e.patch
* Required
* 0002-Support-fcitx.patch
* Required
* 0003-Change-compiler-from-clang-to-gcc.patch

* Required. (maybe)
* 0005-Enable-verbose-build.patch
* Required.
* 0006-Update-gyp-using-absl.patch
