Bugfix Issue #1915 — jiraCommons::initDefaultResolvedStatus() warns for JIRA status sets without literal Resolved/Closed

Follow-up of #1914 (same helper, different defect): filed while testing that fix (see the "Related" note in docs/bugfix-issue-1914-php82-dynamic-properties.md).

Symptom

jiraCommons::initDefaultResolvedStatus() (lib/issuetrackerintegration/jiraCommons.class.php) hardcodes the item set array('Resolved','Closed') and indexes the incoming $statusDomain map by those exact names. JIRA status names are fully customizable (and localized), so an instance whose status set is e.g. Done / In Review is entirely legal — and then every call emits two diagnostics and returns a broken map:

PHP Warning: Undefined array key "Resolved" in lib/issuetrackerintegration/jiraCommons.class.php on line 93
PHP Warning: Undefined array key "Closed"   in lib/issuetrackerintegration/jiraCommons.class.php on line 93

The returned entries get code => null, so nothing can ever be classified as resolved. Unlike the E_DEPRECATED noise of #1814/#1915-sibling reports, E_WARNING is persisted: the web-tier watchPHPErrors() handler writes each one as an Event Viewer row, so a JIRA-linked TestLink install with custom status names gets a Warn row on every POST /api/issuetracker/index.php/test-connection (and any legacy issue-tracker screen that instantiates the interface).

Reachable through jiradbInterface.class.php:72, jirarestInterface.class.php:190, jirasoapInterface.class.php:205.

Root cause

jiraCommons.class.php:87-96:

$itemSet = array('Resolved','Closed'); // Unfortunately case is important
foreach($itemSet as $st) {
  $domain[] = array('code' => $statusDomain[$st], 'verbose' => $st); // line 93
}

$statusDomain is a statusName => statusId map built from the live JIRA status list:

Back-end	Writer	Source
DB	jiradbInterface::getStatuses() :190	SELECT issuestatus.pname
REST	jirarestInterface :186	APIClient->getStatuses()
SOAP	jirasoapInterface :202	SOAP getStatuses()

Line 93 indexes with no isset()/array_key_exists() guard, so a missing name is an undefined-key read (PHP 8 E_WARNING) whose value is null.

The result flows into setResolvedStatusCfg() (jirarestInterface:918, jirasoapInterface:369, base issueTrackerInterface:634) → resolvedStatus->byCode, and is consumed by isResolved = isset($this->resolvedStatus->byCode[$issue->statusCode]) (jiradb:157, jirarest:238, jirasoap:151). A null key becomes byCode[""], which never matches a real status code.

Same defect class as #1608 (undefined array key → PHP 8 diagnostic); not a recent regression — the hardcoding has been there since the helper was written.

Fix (minimal)

Guard the lookup; skip names that are absent.

foreach($itemSet as $st) {
  // Refs #1915: JIRA status names are customizable/localizable, so a domain
  // without these exact keys is legal. Guard the lookup to avoid an
  // "Undefined array key" E_WARNING and a bogus null 'code' entry; missing
  // names are simply skipped and can be supplied via cfg->resolvedstatus.
  if( array_key_exists($st, $statusDomain) ) {
    $domain[] = array('code' => $statusDomain[$st], 'verbose' => $st);
  }
}

No caller changes, no assignment removed. Behavior for instances that do have Resolved/Closed is byte-identical; an explicit cfg->resolvedstatus override in setResolvedStatusCfg() still takes precedence.

Companion hardening (found by the mandated code review). An empty list must not break the DB backend: jiradbInterface uses the base issueTrackerInterface::setResolvedStatusCfg() (:634), which — unlike the REST/SOAP overrides — never initialized byCode. With the fix returning [], the foreach is skipped and array_flip($this->resolvedStatus->byCode) reaches array_flip(null) → fatal TypeError (not caught by catch(Exception)). With two null-code entries this fatal was masked pre-fix, so the guard alone would have converted a warning into an HTTP 500 on JIRA-DB integrations. The base method is now hardened identically to jirasoapInterface::setResolvedStatusCfg():

$this->resolvedStatus->byCode = array();
if( !is_null($statusCfg['status']) ) {
  foreach ($statusCfg['status'] as $cfx) { ... }
}

Alternatives rejected:

• Case-insensitive lookup — still fails for localized section names (Terminé) and would silently mis-classify. Rejected.
• Treat every status actually present as resolved — would classify Open / In Progress as resolved. Rejected.
• Populate a JIRA built-in default map — statuses are per-instance; no such map exists. Rejected.
• Suppress with @ / error_reporting — hides a real null, keeps the broken code. Rejected.

Verification

CLI probes (error handler installed to count warnings):

$ php /tmp/probe_jiracommons.php
warnings=0
result=[]                       # pre-fix: warnings=2, [{"code":null,...},{"code":null,...}]

$ php /tmp/probe_jiracommons_matrix.php
both:    warnings+=0 result=[{"code":"5","verbose":"Resolved"},{"code":"6","verbose":"Closed"}]
one:     warnings+=0 result=[{"code":"5","verbose":"Resolved"}]
neither: warnings+=0 result=[]
total_warnings=0

Gate: TLU_REQUIRE_SUITE="Issue #1915" bash ai/verify_test_suites.sh → exit 0. Suite: Regression — Issue #1915 in tmp/TLU_Test_Cases.md.

Screenshots: none new — the defect is server-side (no screen state changes); the evidence is the warning count (2 → 0) and the map ([null,null] → []).
