Some notes on travisci remote debugging via ssh or screenshot or remote desktop of Mac VM builds

	Some notes on remote debugging mac builds on Travisci. It's hard to tell when something hangs what the cause it. Trial and error via commits is tedious. And on Mac , sometimes it's the gui asking for input. So I worked my around to get the access I needed for faster debugging a build.

	#################################################
	# Enable remote ssh access to travisci build for debugging
	#################################################
	# Add a key so we can login to travisci vm
	- cat ssh/travisci.pub >> ~/.ssh/authorized_keys
	- chmod 600 ssh/travisci

	# Install netcat

Run a shell command in a separate thread, terminate it after a time limit, return its output

	# Runs a specified shell command in a separate thread.
	# If it exceeds the given timeout in seconds, kills it.
	# Returns any output produced by the command (stdout or stderr) as a String.
	# Uses Kernel.select to wait up to the tick length (in seconds) between
	# checks on the command's status
	#
	# If you've got a cleaner way of doing this, I'd be interested to see it.
	# If you think you can do it with Ruby's Timeout module, think again.

danielribeiro / Rakefile

Last active August 27, 2015 08:15 — forked from alloy/Rakefile

A Rakefile that standardises program env installation and guides the user, as opposed to crashing with Ruby exceptions such as `LoadError`. The only case where this will *never* work reliably is if you use the `rubygems-bundler` (NOEXEC) plugin, which introduces chicken-and-egg problems.

	# Do not load any libs here that are not part of Ruby’s standard-lib. Ever.

	desc "Install all dependencies"
	task :bootstrap do
	if system('which bundle')
	sh "bundle install"
	sh "git submodule update --init"
	# etc
	else
	$stderr.puts "\033[0;31m[!] Please install the bundler gem manually: $ [sudo] gem install bundler\e[0m"
