That's the code:

error_log("ThOr: opening server: ".$this->server);
        $conn = @imap_open('{'.$this->server.'}'.$this->folder, $this->login, $this->passwd, 0);
error_log("ThOr: DONE opening server: ".$this->server);

So that in the log...

[Tue Mar 06 17:31:28 2012] [error] [client x] ThOr: opening server: bla
[Tue Mar 06 17:31:29 2012] [error] [client x] ThOr: DONE opening server: bla

Does mean that the call to imap_open didn't need more than one second, doesn't it? I might be wrong, I'm just transferring my knowledge from other programming languages.

Where would that output go? I prefer it showing up in the apache logs, hence error_log seemed fine (also as there are timestamps).

That is interesting. Are we having two different issues here? Or am I wrong about when error_log messages get sent to apache? Trying again with that code:

error_log("ThOr: opening server: ".$this->server);
$begin = microtime(true);
        $conn = @imap_open('{'.$this->server.'}'.$this->folder, $this->login, $this->passwd, 0);
$end = microtime(true);
error_log("ThOr: DONE opening server: ".$this->server);
error_log("needed time:".($end-$begin));

[Wed Mar 07 01:30:34 2012] [error] [client x] ThOr: opening server: bla
[Wed Mar 07 01:30:34 2012] [error] [client x] ThOr: DONE opening server: bla
[Wed Mar 07 01:30:34 2012] [error] [client x] needed time:0.0717890262604, bla
[Wed Mar 07 01:31:02 2012] [error] [client x] ThOr: num_msg, bla
[Wed Mar 07 01:31:02 2012] [error] [client x] ThOr: num_msg, bla
[Wed Mar 07 01:31:04 2012] [error] [client x] ThOr: num_msg, bla

So I need to dig around what happens in between... are we really talking about the same line of code in class_local.php?

Well, if I keep using it, I will have a look at that JavaScript code that is there, but it doesn't seem to be that important. For one, there is the "invert selection" (Invertiere Auswahl) button that doesn't work without. Well, for non-scripters, a "select all" button would be nice as addition. Well, small things, not hard to do.


Alrighty then,

Thomas.
