Popup nag removal - script

Proxmox VE nag removal, scripted

This is a follow-up on the method of manual removal of the “no valid subscription” popup, since the component is being repeatedly rebuilt due to active GUI development.

The script is simplistic, makes use of Perl (which is part of PVE stack) and follows the exact same steps for the predictable and safe outcome as the manual method did. Unlike other scripts available, it does NOT risk partial matches of other (unintended) parts of code in the future and their inadvertent removal, it also contains the exact copy of the JavaScript to be seen in context.

Script

#!/usr/bin/perl -pi.bak

use strict;
use warnings;

# original
my $o = quotemeta << 'EOF';
    checked_command: function(orig_cmd) {
	Proxmox.Utils.API2Request(
	    {
		url: '/nodes/localhost/subscription',
		method: 'GET',
		failure: function(response, opts) {
		    Ext.Msg.alert(gettext('Error'), response.htmlStatus);
		},
		success: function(response, opts) {
		    let res = response.result;
		    if (res === null || res === undefined || !res || res
			.data.status.toLowerCase() !== 'active') {
			Ext.Msg.show({
			    title: gettext('No valid subscription'),
			    icon: Ext.Msg.WARNING,
			    message: Proxmox.Utils.getNoSubKeyHtml(res.data.url),
			    buttons: Ext.Msg.OK,
			    callback: function(btn) {
				if (btn !== 'ok') {
				    return;
				}
				orig_cmd();
			    },
			});
		    } else {
			orig_cmd();
		    }
		},
	    },
	);
    },
EOF

# replacement
my $r = << 'EOF';
    checked_command: function(orig_cmd) {
	Proxmox.Utils.API2Request(
	    {
		url: '/nodes/localhost/subscription',
		method: 'GET',
		failure: function(response, opts) {
		    Ext.Msg.alert(gettext('Error'), response.htmlStatus);
		},
		success: function(response, opts) {
			orig_cmd();
		},
	    },
	);
    },
EOF

BEGIN { undef $/; } s/$o/$r/;

Shebang ¹ arguments provide for execution of the script over input, sed-style (-p), ² and also guarantee a backup copy is retained (-i.bak).

Original pattern ($o)and its replacement ($r) are assigned to variables using HEREDOC ³ notation in full, the original gets non-word characters escaped (quotemeta) for use with regular expressions.

The entire replacement is in a single shot on multi-line (undef $/;) pattern, where original is substituted for replacement (s/$o/$r/;) or, if not found, nothing is modified.
