Using strace and lsof to debug blocked processes

You can use strace on a specific pid to figure out what a specific process is doing, e.g.:

strace -fp <pid>

You might see something like:

select(9, [3 5 8], [], [], {0, 999999}) = 0 (Timeout)

Locate the section for your github remote in the .git/config file. It looks like this:

[remote "origin"]
	fetch = +refs/heads/*:refs/remotes/origin/*
	url = [email protected]:joyent/node.git

Now add the line fetch = +refs/pull/*/head:refs/remotes/origin/pr/* to this section. Obviously, change the github url to match your project's URL. It ends up looking like this:

	<?php

	// Inside your action

	$this->serializer = new \Symfony\Component\Serializer\Serializer();
	$this->serializer->addNormalizer(new \Symfony\Component\Serializer\Normalizer\GetSetMethodNormalizer());
	$this->serializer->setEncoder('xml', new \Symfony\Component\Serializer\Encoder\XmlEncoder());

	return $this->createResponse($this->serializer->encode($page, 'xml'), 200, array('Content-Type' => 'application/xml'));

	// This function allows creating a new function from two functions passed into it
	function compose(&$f, &$g) {

	$ git branch -r --merged \|
	grep origin \|
	grep -v '>' \|
	grep -v master \|
	xargs -L1 \|
	awk '{split($0,a,"/"); print a[2]}' \|
	xargs git push origin --delete
