PHP, Symfony2, Erlang, Linux and everything else!

Stuff i encounter when working with computers. Do not expect magic here, just some notes about problems, solutions and handy things i meet.

Use ISO8601 date format correct for JavaScript from JMS Serializer

We ran into a 'problem', where JavaScript could not process the dates given by PHP via JMS Serializer correctly.

I found out, that the date('c') does not create timezones like the needed '+20:00', but '+2000'.

Changing the 'c' to 'Y-m-d\TH:i:sP' fixes the whole thing. JMS Serializer configuration offers this here: http://jmsyst.com/bundles/JMSSerializerBundle/master/configuration

Add a help target to your ant build.xml buildfiles

Creating a self-documenting buildfile sound reasonable, so lets do so.

I followed the idea on this site http://amazing-development.com/archives/2005/01/28/ant-help-target/ and created the following task in a project of mine:

<target name="help"> <echo>--- Help for Project X ---</echo> <echo>This buildfile is mainly used for automatic continuous integration jobs.</echo> <echo>There is also a target 'foo' for doing bar-things.</echo> <echo/> <!-- Display available targets via ant itself --> <exec executable="ant"> <arg value="-p"/> </exec> </target>

Generate external URLs from a Symfony2 route

Aim was to have a route, that will return a external url. This is not possible with Sf2, because only internal Urls can be generted by the standard framework.

But thanks to DependencyInjetion, it was quite easy to extend the UrlGenerator with the desired functionality.

Have a look at the code:

With this it is possible to have a named route, that will generate a external link.

UpStart respawn only when process exited with exitcode != 0

I fell for the handling of upstart with the stanza respawn documented here: http://upstart.ubuntu.com/cookbook/#respawn

A process HAS to exit with a exitcode != 0 to be restarted. Changed that to force a restart from my script.

UpStart redirect output of exec to a file

Tried to redirect the stdout and stderr output of a script started via upstart to a file. This failed in a strange way, because multiple instances of the script were started. I used this code:

exec php /home/h4cc/foo.php &> /home/h4cc/foo.log

Solutions was to use this command instead:

exec php /home/h4cc/foo.php > /home/h4cc/foo.log 2>&1

It seems as if upstarts exec gets confused by the amperesand ...

Symfony2 Swiftmailer does not send mails in Commands.

The Symfony2 Swiftmailer does not send mails that are spooled in 'memory', because of a missing 'kernel.terminate' Event when used in a Command.

More on that: http://sgoettschkes.blogspot.de/2012/09/symfony-21-commands-and-swiftmailer.html

Solutions:

Use 'file' spooling and send mails with 'swiftmailer:spool:send'.

Add some code in the Command to flush spool by hand

$container = $this->getContainer(); $mailer = $container->get('mailer'); $spool = $mailer->getTransport()->getSpool(); $transport = $container->get('swiftmailer.transport.real'); $spool->flushQueue($transport);
