I had several:

Generating code coverage report, this may take a moment.PHP Fatal error: Allowed memory size of 268435456 bytes exhausted (tried to allocate 21503527 bytes) in /usr/share/php/PHPUnit/Util/Report/Node/File.php on line 406

And here is how it started:

At work we are using phpunit to test our framework, we flew from SimpleTest as there was no real integration with our tools and no real followup of the the product.

So to automate the test, as there is no “build” in php (interpreted vs compiled remember?) we ran it after each commit …

Until it tooks 30 minutes to run throught the whole set of tests…

Then we decided to run it locally before comitting… until it tooks up to 2 hours to run tests (yes we have slow laptops I know, at least 4 times slower than the servers).

Actually we use phpunit for recipe test, including database change, third parties, providers… everything from A to Z… and that needs a lot of time and CPU power…

So we solved the problem by running test in a cronjob, hourly on the integration server.

This was done running phpunit in command line


> phpunit --include-path ../code/ MyTestSuite.php


Of course as we had several tests suites and we had to put them all in one bigger testsuite… but that was not easy so we moved to the Phpunit config file, added code coverage reporting and send a mail everytime sometimes goes wrong

That’s it for the big picture…

And as you can see there are several point in the XML that are quite important:

memory limit 2047MBthat’s huge… but this is the price to pay to have a fully working code-coverage HTML report. As we are using suhosin we had to change the memory limit in suhosin too… and yes when the limit is 2048 MB don’t try to set the memory to 2048 MB it really means this is a limit you have to be under that limit (here 2047 MB).

2 Gigs!!! I know this is huge but believe me I went through several tries and 128 MB was not enought, nor 256 MB, nor 512 MB, not even 1 GB … I didn’t try to see where is my limit … I put 2 gigs and then it worked… we have about 30% of lines covered so I think that if we shift to 100% we will have to give more memory… I’m pretty sure, there is something leaking somewhere… but according to phpunit.de site… I have the answer remains: Give more memory

/etc/php5/conf.d/suhosin.ini

logging is commented out because logging needs xdebug and while we stay with ZendServer CE we do not have xdebug… (see my previous post for more info).

But the server which is not running Zend Server CE does!

So I commented out the line in the config to let developers run the unit test and pasted it as command line argument on the server’s cronjob.

phpunit --include-path ../code/ --coverage-html /reporting/phpunit/library/ --configuration PhpunitConfig.xml

the listener This is a simple easy listener. It’s always useful to have one sample so I pasted here above, feel free to copy, enhance… The only ‘hack’ we use it to call the send email on listener destruction, so the email will be sent at the end. But there is a drawback… if there is a php error somewhere, nothing is sent. And as nothing is sent when everythign goes well… we dont know if everythings goes well or if there is a real bug…
This problem will be addressed later. Stay tuned!

• Calculate distance, bearing and more between two Latitude/Longitude points
• Geocoding Belgium Postal Codes

The goal of my project was to find out which cities are nearby (within a user specified distance).
Of course users don’t know their city coordinate, so you will have to find out by yourself. To do so, I used the JEDI trick (Geocoding Belgium Postal Codes) which is:

Downloading the csv of cities and zip code (available on the national mail site for Belgium, I don’t know for other countries)
Writing a small piece of code to parse the csv and retrieve the right latitude and longitude via google geo service

I could have downloaded the file from the JEDI site but I really needed to do it by myself.

So the next thing to do is: finding the cities within an arbitrary distance.

This was based on the documentation I found on the movable-type math site.

All I did is translating the Javascript function to PHP functions:

    private function sphericalDistance($lat1,$lon1,$lat2,$lon2){
        $R = 6371.0; // km
        $d = acos(
                sin(deg2rad($lat1))*sin(deg2rad($lat2))
                + cos(deg2rad($lat1))*cos(deg2rad($lat2))
                * cos(deg2rad($lon2-$lon1))
             )
             * $R;
        return $d;
    }

    private function haversineDistance($lat1,$lon1,$lat2,$lon2){
        $R = 6371.0; // km
        $dLat = deg2rad($lat2-$lat1);
        $dLon = deg2rad($lon2-$lon1);
        $a = sin($dLat/2) * sin($dLat/2)
            + cos(deg2rad($lat1)) * cos(deg2rad($lat2))
            * sin($dLon/2) * sin($dLon/2);
        $c = 2.0 * atan2(sqrt($a), sqrt(1-$a));
        $d = $R * $c;
        return $d;
    }

    private function vincentyDistance($lat1,$lon1,$lat2,$lon2){
        $a = 6378137.0; $b = 6356752.3142;  $f = 1/298.257223563;  // WGS-84 ellipsiod
        $L = deg2rad($lon2-$lon1);
        $U1 = atan((1-$f) * tan(deg2rad($lat1)));
        $U2 = atan((1-$f) * tan(deg2rad($lat2)));
        $sinU1 = sin($U1);
        $cosU1 = cos($U1);
        $sinU2 = sin($U2);
        $cosU2 = cos($U2);
        $lambda = $L;
        $lambdaP = $L;
        $iterLimit = 100;
        do{
            $sinLambda = sin($lambda);
            $cosLambda = cos($lambda);
            $sinSigma = sqrt(($cosU2*$sinLambda) * ($cosU2*$sinLambda) +
                        ($cosU1*$sinU2-$sinU1*$cosU2*$cosLambda) * ($cosU1*$sinU2-$sinU1*$cosU2*$cosLambda));
            if($sinSigma==0) return 0;
            $cosSigma = $sinU1 * $sinU2 + $cosU1*$cosU2*$cosLambda;
            $sigma = atan2($sinSigma, $cosSigma);
            $sinAlpha = $cosU1 * $cosU2 * $sinLambda / $sinSigma;
            $cosSqAlpha = 1 - $sinAlpha*$sinAlpha;
            if($cosSqAlpha!=0){
                $cos2SigmaM = $cosSigma - 2*$sinU1*$sinU2/$cosSqAlpha;
            }else{
                $cos2SigmaM =0;
            }
            $C = $f/16*$cosSqAlpha*(4+$f*(4-3*$cosSqAlpha));
            $lambdaP = $lambda;
            $lambda = $L + (1-$C) * $f * $sinAlpha *
                    ($sigma + $C*$sinSigma*($cos2SigmaM+$C*$cosSigma*(-1+2*$cos2SigmaM*$cos2SigmaM)));
        }while(abs($lambda-$lambdaP) > 1e-12 && --$iterLimit>0);
        if($iterLimit == 0) return false; // formula failed to converge
        $uSq = $cosSqAlpha * ($a*$a - $b*$b) / ($b*$b);
        $A = 1 + $uSq/16384.0*(4096+$uSq*(-768+$uSq*(320-175*$uSq)));
        $B = $uSq/1024.0 * (256+$uSq*(-128+$uSq*(74-47*$uSq)));
        $deltaSigma = $B*$sinSigma*($cos2SigmaM+$B/4*($cosSigma*(-1+2*$cos2SigmaM*$cos2SigmaM)
                    - $B/6*$cos2SigmaM*(-3+4*$sinSigma*$sinSigma)*(-3+4*$cos2SigmaM*$cos2SigmaM)));
        $s = $b*$A*($sigma-$deltaSigma);
        return $s/1000.0;
    }

And that’s it…

So if you want the php serialized cities of Belgium with Zip, cityname, uppercase cityname, longitude,latitude.

I didn’t do a lot at all, just put every source together.

H! I find your post interesting. I am pretty chick. I am moving to your area from russia
I am looking for a good man to show me around and may be more ;)
Could you please kindly reply to me at jclapptakomapark@gmail.com
I will send you some of my pictures back in reply.
Could you reply to my email account I am supplying in the body of this email as I am writing from my work email which i don’t use for personal correspondence

Windows Live™: Keep your life in sync. Check it out.

–> Don’t use quechup

I prefere to do research and to develop than to maintain out-sourced code…

Why do they outsource the great applications and concepts… and leave us with the day to day operationnal work…

That’s not nice…

So I decided to resign… Bye bye Skynet… I hope that you will see the light sooner or later… and stop your self-destruction…

svn diff > mypatch_xx.diff

After the commit:

svn diff -r > mypatch_xx.diff

copy the mypatch_xx.diff file at the same relative place on the other computer/directory/…

and do:

patch --dry-run -p0 -i ~/mypatch_xx.diff

to see what will be done and then

patch -p0 -i ~/mypatch_xx.diff

to do it really

to install patch: apt-get install patch
to install subversion: apt-get install subversion

You must be root (or able to sudo)!

1. check that cgi-bin mod_alias is activated

in /etc/apache/httpd.conf search for:

<IfModule mod_alias.c>
#ScriptAlias /cgi-bin/ /usr/lib/cgi-bin/
...


the line should be uncommented

2. Install php5-cgi

update:


apt-get update


simulate install:


apt-get -s install php5-cgi
Reading package lists... Done
Building dependency tree... Done
The following NEW packages will be installed
php5-cgi
0 upgraded, 1 newly installed, 0 to remove and 0 not upgraded.
...


if you have something similar, let’s do it for real

apt-get install php5-cgi


3. add an handler in the directory where php5 files are

in the directory where you want to have php5 running (ex: /var/www/myphp5site/)
create an .htaccess file containing:

AddHandler x-httpd-php5 .php
Action x-httpd-php5 /cgi-bin/php5


4. gracefuly restart apache

apachectl graceful


It’s done, enjoy.
