Bug 681635: De-duplicate values in Advanced Search

[loganrosen]

Details

Advanced Search can show duplicate version or target milestone values when selected products use configured ordering rather than case-insensitive alphabetical ordering. merge_arrays used a two-pointer merge that assumed both inputs were already sorted, so overlapping values at different positions were not recognized as duplicates.

This is the Harmony port of bugzilla/bugzilla#244. It combines both inputs, sorts them case-insensitively, and removes adjacent case-insensitive duplicates while preserving the incremental <select> options path. A Perl TAP regression executes the production JavaScript with Node. The dedicated release-test image installs and requires Node.js, while Node-less runtime and sanity images skip the test. Runtime images are unchanged.

Test Plan

1. Run bash docker/run-tests-in-docker.sh release; confirm all 28 files and 14,205 tests pass, including t/015productform.t.
2. Run docker compose -f docker-compose.test-mysql.yml run --no-deps --rm bugzilla6.test test_sanity t/*.t extensions/*/t/*.t; confirm all 32 files and 14,229 tests pass, with t/015productform.t skipped in the intentionally Node-less image.
3. Hide Node from the release image and confirm t/015productform.t fails because BZ_REQUIRE_NODE=1.
