(Overly?) Slow parsing #184
Description
- PHP Version:
7.1.16 - PHP date.timezone:
UTC - ICS Parser Version:
2.1.5 Windows/Mac/Linux
Description of the Issue:
Parsing the attached exchange.ics.txt takes some 3s. For my use case this is way too slow but I have no idea if this is considered "normal" with this library. Before I download & configure Xdebug (PHP is not my home turf) to see where those milliseconds are lost I would like to know how you assess this case.
File size: 160KB
Number of events: 242
When expanded with span 1: 512
Steps to Reproduce:
<?php
date_default_timezone_set("UTC");
require_once "./vendor/autoload.php";
use ICal\ICal;
$calendarString = "";
try {
$ical = new ICal(array(
"defaultSpan" => 1, // Default value: 2
"defaultWeekStart" => "MO", // Default value
"disableCharacterReplacement" => false, // Default value
"skipRecurrence" => false, // Default value
"useTimeZoneWithRRules" => false, // Default value
));
$millis = getMillis();
$ical->initString($calendarString);
echo "ical->initString() took " . (getMillis() - $millis) . "ms\n";
$events = $ical->events();
echo "calendar contains " . sizeof($events) . " events (recurring span: 1y)\n";
} catch (\Exception $e) {
die($e);
}
function getMillis() {
return round(microtime(true) * 1000);
}I pasted the content of the file exchange.ics.txt into $calendarString.
