Folder->idle CPU 100%

[WaldemarOrobanche]

Describe the bug
The while(true) contains the condition that sometimes doesn't match and runs without timeout that will gonna to take all CPU resources. The same could happen at the catch block, because callback could throw any type of exception.

php-imap/src/Folder.php

Lines 369 to 391 in 5437529

	while (true) {
	try {
	$line = $connection->nextLine();
	if (($pos = strpos($line, "EXISTS")) !== false) {
	$msgn = (int) substr($line, 2, $pos -2);
	$connection->done();
	$this->client->openFolder($this->path, true);
	$message = $this->query()->getMessageByMsgn($msgn);
	$message->setSequence($sequence);
	$callback($message);
	$event = $this->getEvent("message", "new");
	$event::dispatch($message);
	$connection->idle();
	}
	}catch (Exceptions\RuntimeException $e) {
	if(strpos($e->getMessage(), "connection closed") === false) {
	throw $e;
	}
	}
	}

Expected behavior
Normal usage of CPU

Hi @WaldemarOrobanche ,
thanks for your report.

I have a few questions though:

• Can you specify the conditions which lead to this behavior?
• How can this be reproduced?
• Does this only occur with one specific account / mail provider?
• How does your code look like which:
  • initialize the Client::class instance?
  • initialize the Folder::class instance?
  • call the Folder::idle() method?
• Which webklex/php-imap version are you using?
• Which operating system are you using?

Best regards,

Can you specify the conditions which lead to this behavior?

• when the $line variable holds * OK Still here.
• when an exception occurs like failed to read - connection closed?.
