Issue #638 — count(null) TypeError in resultsTCAbsoluteLatest.php when test plan has no builds

Issue: #638 Status: VERIFIED-FIXED (2026-08-26)

Root Cause

lib/results/resultsTCAbsoluteLatest.php:313 called count($guiObj->buildInfoSet) directly. testplan::get_builds() returns null when no builds exist for the plan. PHP 8.0+ treats count(null) as a fatal TypeError.

This is the identical bug as issue #634, which fixed the same pattern in resultsTC.php and resultsTCFlat.php but missed this file.

Fix

Applied the same ternary null guard already present in the sibling files:

// Before (line 313):
$guiObj->activeBuildsQty = count($guiObj->buildInfoSet);

// After:
// issue #634: a plan without builds returns null here =>
// count(null) is a TypeError on PHP 8
$guiObj->activeBuildsQty = is_null($guiObj->buildInfoSet) ?
                           0 : count($guiObj->buildInfoSet);

Files Changed

• lib/results/resultsTCAbsoluteLatest.php — line 313: added null guard

Verification

• php -l — no syntax errors
• HTTP 200 on test plan with zero builds (was HTTP 500 before fix)
• Page renders correctly: heading + platform selector form
• No new errors in server log or Event Viewer
• Sibling pages (resultsTC.php, resultsTCFlat.php) return HTTP 200 (regression check passed)
