somethingwithproof · 2026-04-09T21:09:30Z

This PR adds strict typing, short array syntax, and null coalescing operators across the plugin. Standalone infrastructure files were removed per architectural mandate.

Pull request overview

This PR aims to modernize the thold plugin by enabling strict_types and refactoring various PHP constructs across the codebase, as well as adjusting ancillary files.

Changes:

Added declare(strict_types=1); to many PHP entrypoints and helper files.
Refactored several array/XML helper call sites and action hook functions (currently introduces invalid PHP syntax in multiple places).
Added .omc/sessions/*.json session metadata files to the repo.

thold_webapi.php:184

This function declaration is invalid PHP syntax (square brackets in the parameter list). It will cause a parse error and break the plugin; restore a normal parameter list (e.g., keep the original thold_add_graphs_action_array($action) signature).
setup.php:739
This function declaration is invalid PHP syntax (function ..._[$device_action_array]). It should be a normal function name and parameter list; otherwise setup.php will not parse.
setup.php:1026
This function declaration is invalid PHP syntax (function ..._[$action]). It will cause a parse error; keep the original thold_data_source_action_array($action) style signature.
setup.php:1190
This function declaration is invalid PHP syntax (function ..._[$action]) and will prevent the plugin from loading. Restore a normal parameter list (e.g., thold_graphs_action_array($action)).
setup.php:1688
This function declaration is invalid PHP syntax (function ..._[$regex_array]). It will cause a parse error; restore a normal function signature (e.g., thold_clog_regex_array($regex_array)).

setup.php

 	$defs = explode("\\\n", $g['graph_defs'], -1);

-	if (is_array($defs)) {
+	if (is_[$defs]) {
 		foreach ($defs as $def) {


is_[$defs] is not a valid PHP call and will trigger a parse error. This should remain a normal array check (e.g., is_array($defs)) before iterating.

Copilot · 2026-04-09T21:14:02Z

setup.php

 	$i      = 0;
 	$unsets = [];

-	if (is_array($replacements)) {
+	if (is_[$replacements]) {
 		foreach ($txt_items as $item) {


is_[$replacements] is invalid PHP syntax and will cause a parse error. Use a standard array check (e.g., is_array($replacements)) or remove the condition if it’s redundant.

thold_templates.php

+	if ((isset($_SESSION['import_debug_info'])) && (is_[$_SESSION['import_debug_info']])) {
 		html_start_box(__('Import Results', 'thold'), '80%', false, '3', 'center', '');



is_[$_SESSION['import_debug_info']] is invalid PHP syntax and will cause a parse error. This should remain a standard is_array(...) check before iterating.

includes/polling.php

 		foreach ($hosts as $host) {
 			// hosts in recovery status record only if they was in failed status
-			if (($host['status'] != HOST_RECOVERING) || ($host['status'] == HOST_RECOVERING && (is_array($failed) && array_search($host['id'], array_column($failed, 'host_id'), true) !== false))) {
+			if (($host['status'] != HOST_RECOVERING) || ($host['status'] == HOST_RECOVERING && (is_[$failed] && array_search($host['id'], array_column($failed, 'host_id'), true) !== false))) {
 				$failed_ids .= ($failed_ids != '' ? '), (' : '(') . $host['id'];
 			}


is_[$failed] is invalid PHP syntax and will cause a parse error. This should remain a standard is_array($failed) (or equivalent) check before using array_column / array_search.

cli_import.php

 $data = file_get_contents($filename);

-$xml  = xml2array($data);
+$xml  = xml2[$data];

-if (!is_array($xml) || !cacti_sizeof($xml)) {
+if (!is_[$xml] || !cacti_sizeof($xml)) {


xml2[$data] and is_[$xml] are invalid PHP syntax and will cause a parse error. This should call the XML parser function (e.g., xml2array($data)) and then validate with is_array($xml) / cacti_sizeof($xml).

Copilot · 2026-04-09T21:14:05Z

thold_functions.php

 	$version = db_fetch_cell("SELECT version
 		FROM plugin_config
 		WHERE directory='thold'");

-	if (!is_array($headers)) {
+	if (!is_[$headers]) {
 		$headers = [];
 	}


!is_[$headers] is invalid PHP syntax and will cause a parse error during email generation. Use !is_array($headers) (or remove the guard if $headers is always an array).

Copilot · 2026-04-09T21:14:05Z

thold_functions.php

 	if (cacti_sizeof($array)) {
 		foreach ($array as $key=>$value) {
-			if (is_array($value)) {
+			if (is_[$value]) {
 				$xml .= "\t<$key>" . ia2xml($value) . "</$key>\n";
 			} else {


is_[$value] is invalid PHP syntax and will cause a parse error in this XML serialization helper. This should be is_array($value).

Copilot · 2026-04-09T21:14:05Z

thold_functions.php

 	if ($xml_data != '') {
 		// obtain debug information if it's set
-		$xml_array = xml2array($xml_data);
+		$xml_array = xml2[$xml_data];



xml2[$xml_data] is invalid PHP syntax and will cause a parse error. This should call the XML parsing function (e.g., xml2array($xml_data)) before iterating the resulting array.

The PR description mentions that standalone infrastructure files were removed, but the systemd artifacts are still present in the tree (e.g., service/systemd/thold_daemon.service). Either update the PR description or remove/move the infrastructure files as intended.

This appears to be tool/session metadata (.omc/sessions/...) and not part of the plugin runtime. It should be removed from the PR and added to .gitignore to avoid committing local session artifacts.
