Fun with windows subsystem for linux

After the install and the required reboot I was able to start bash. At first I was confused where to find the files from the home directory. It isn’t the one from windows itself.
Well I found it in AppData\Local\lxss . So each user has his / her own files.

Since I was able to find most stuff I wanted to know if I am able to compile httpd apache on it. I cloned and the build went smooth.
But apache didn’t start. Adding AcceptFilter http none and AcceptFilter https none helped. To get rid of the first error messages. But still apache wasn’t starting. Got the following error message.

[Tue Jan 24 22:31:33.590385 2017] [fcgid:emerg] [pid 1289:tid 140034843477824] (38)Function not implemented: mod_fcgid: Can't create shared memory for size 1200712 bytes

Okay, I disabled mod_fcgid and apache starts with /opt/apache2/bin/httpd -k start . Even running C:\Windows\System32\bash.exe ~ as Adminstrator did not solve to run fcgid.
I have to find out how to run mod_fcgid. I like to run PHP over fcgid.

mod_fcgid is polluting my error log on windows

Well I really like mod_fcgid with PHP on my Apaches on Windows. But since every time a PHP process get it’s signal to die, mod_fcgid creates on windows an entry in the error log cause the graceful stop always fails.

There in a patch for that! I made a bug report (54597), but it didn’t go in the code yet.  If you wanna patch it yourself, here it is.

__toString() must not throw an exception

__toString() must not throw an exception.


If you an exception handler even that seems fail (in itself) with __toString() must not throw an exception. There is no nice safe way to handle it. The easiest solution is to catch that error as well. It might seems to be odd, but on the other hand the exception hanler shall not fail ;)

* String representation of this object
* @return string
public function __toString()
try {
return (string) $this->name;
} catch (Exception $exception) {
return '';

UPDATE `table` set
    `column`= REPLACE(`column`,"ß", "ß"),
    `column`= REPLACE(`column`, "ä", "ä"),
    `column`= REPLACE(`column`, "ü", "ü"),
    `column`= REPLACE(`column`, "ö", "ö"),
    `column`= REPLACE(`column`, 'Ä', 'Ä'),
    `column`= REPLACE(`column`, "Ãœ", "Ü"),
    `column`= REPLACE(`column`, "Ö", "Ö"),

Ajax Undzeichen ( &) übertragen

Normalerweise gibt es ein Problem beim Übertragen von Daten per AJAX, wenn sich ein & Zeichen in dem zuübertragenden Text / Daten befindet. Das Javascript interpretiert das Undzeichen als Trennzeichen. Alles nach dem & Zeichen wird nicht mehr übertragen. Abhilfe schafft hier die funktion encodeURIComponent


var save_data = 'save_text=' + encodeURIComponent($(".edit_textarea").val());
		//return false;
			type: 'POST',
			url: 'ajax.php',
			data: save_data,
			success: function (msg){
				console.log('OK: ' + msg);
			error:function (xhr, ajaxOptions, thrownError){

Jetzt kommen die Daten auch an.

Zend framework lucene UTF-8 problem

I had issues with the zend framework and its implementation of lucene. It saved the values from my UTF-8 database in the lucene files with characters like UTF-8 in ISO 8859-1 like on the search result page. And I wasn’t able to search case insensitive.

I noticed that the apache header (zend server CE) wasn’t sending UTF-8. So I added AddDefaultCharset utf-8 to my httpd.conf. Didn’t help.

What helped: In the Bootstrap.php adding to the init of the search

Zend_Search_Lucene_Analysis_Analyzer::setDefault(new Zend_Search_Lucene_Analysis_Analyzer_Common_Utf8());
Zend_Search_Lucene_Analysis_Analyzer::setDefault(new Zend_Search_Lucene_Analysis_Analyzer_Common_Utf8_CaseInsensitive());

In the model it is needed to decode it to ISO 8859-1 and than save it as UTF-8. Sounds insane, but it was the only thing that works for me.


WTF Zend Lucene!

JQuery Ajax cross domain request

If you try to do an ajax request on a different domain. You’ll get nothing. Looking a bit deeper into the request I noticed that the status code isn’t 200 or 403 nor 404 like expected. Nope it is 0. (jquery ajax statusCode 0). This means the browser doesn’t allow a crossdomain request. The easiest way for me to solve this was to create a proxy php script. Now I can send my ajax request to a url on my server while the PHP script does the real request to the other server.

This is the php script

* GetFromHost()
* @param string $host
* @param int $port
* @param string $path
* @param string $referer
* @param bool $keepalive
* @return
function GetFromHost($host, $port, $path, $referer,$keepalive=false) {

 $fsocket = fsockopen($host, 80, $errno, $errstr, 30);

 $request =     "GET $path HTTP/1.1\r\n";
 $request .= "Host: $host\r\n";
 $request .= "Referer: $referer\r\n";
 $request .= 'User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.2.1) ';
 $request .= "Gecko/20021204\r\n";
 $request .= 'Accept: text/xml,application/xml,application/xhtml+xml,';
 $request .= 'text/html;q=0.9,text/plain;q=0.8,video/x-mng,image/png,';
 $request .= "image/jpeg,image/gif;q=0.2,text/css,*/*;q=0.1\r\n";
 $request .= "Accept-Language: en-us, en;q=0.50\r\n";
 //$request .= "Accept-Encoding: gzip, deflate, compress;q=0.9\r\n";
 $request .= "Accept-Charset: ISO-8859-1, utf-8;q=0.66, *;q=0.66\r\n";
 $request .= "Keep-Alive: 300\r\n";
 $request .= "Connection: keep-alive\r\n";
 $request .= "Connection: close\r\n";
 //$request .= "Content-Type: application/x-www-form-urlencoded\r\n";
 //$request .= "Content-length: ". strlen($data_to_send) ."\r\n";
 $request .= "\r\n";
 //$request .= $data_to_send;

 fputs($fsocket, $request);

 $res ='';
 while(!feof($fsocket)) {
 $res .= fgets($fsocket, 1024);

 return $res;

 return false;
 //echo "Fehlgeschlagen: ".$fsocket . $host .':'. $port;


$x = GetFromHost("www.example", "80", "/deep/url/kinda/", "");
$x = explode('Content-Type: text/html',$x);
$output = preg_replace('/\s+(\r\n|\r|\n)/', '$1', $x['1']);//remove white space and tabs at the line ends
echo $output;

maybe you have to edit the explode part for server to separate the header fom the real content.

mod lua error handling sux

I still dislike the 500 error handling in lua. Well scripting got easier with practicing :P But the error handling realy sux a lot compared to PHP where I come from. I made a bit “benchmarking”. OK I took very different scripts, but PHP seems faster to me than lua. Plus for lua is that you are able to write direcly into apache log files.

Disable AllowOverride (htaccess to httpd.conf)

AllowOverride is one of the things that slow down a lot. Disabling it makes apache faster. It is a horror to migrate all .htaccess files by hand. BUT here is a PHP script from Paul Reinheimer which makes it realy easy :-)

Get it htaccess.php

tune your server!
