Finding a Ruby memory leak using a time analysis

When developing a program in Ruby, you may sometimes encounter a memory leak. For a while now, Ruby has a facility to gather information about what objects are laying around: ObjectSpace.

There are several approaches one can take to debug a leak. This discusses a time-based approach, where a full memory dump is generated every, say, 5 minutes, during a time that the memory leak is showing up. Afterwards, one can look at all the objects, and find out which ones are staying around, causing the

How to automate the build of bottles on your Homebrew tap

Note on Oct 4, 2018: due to a change in Homebrew's brew test-bot behaviour, the user must set HOMEBREW_TRAVIS_CI and HOMEBREW_TRAVIS_SUDO appropriately (it was previously using Travis-CI-provided TRAVIS and TRAVIS_SUDO).

This tutorial is a follow-up to the discussion we had on davidchall/homebrew-hep#114. It relies on a fork of the test-bot provided by davidchall; you can get it with brew tap maelvalais/test-bot. First:

the Github project must be of the form https://github.com//homebrew- with the following tree

	config.log_tags = [
	:remote_ip,
	->(req){
	if user_id = WardenTaggedLogger.extract_user_id_from_request(req)
	"#" + user_id.to_s
	else
	"guest"
	end
	}
	]

	brews = []
	out = IO.popen("brew list", "r") do \|io\|
	brews = io.read.split "\n"
	end

	def parse(brew, brew_info)
	in_options = false
	print "brew reinstall -v #{brew} "
	brew_info.split("\n").each do \|m\|
	#puts m.inspect

	# config/routes.rb
	resources :documents do
	scope module: 'documents' do
	resources :versions do
	post :restore, on: :member
	end

	resource :lock
	end
	end

	package main

	import (
	"net/http"
	"database/sql"
	"fmt"
	"log"
	"os"
	)

	my setDoNotDisturbON()

	say "Do not disturb is on now" using "Samantha"

	delay 600

	my setDoNotDisturbOFF()

	say "Do not disturb is off. Welcome to hell!" using "Samantha"
