#!/usr/bin/python # This program makes Debian and RPM repositories for MongoDB, by # downloading our tarballs of statically linked executables and # insinuating them into Linux packages. It must be run on a # Debianoid, since Debian provides tools to make RPMs, but RPM-based # systems don't provide debian packaging crud. # Notes: # # * Almost anything that you want to be able to influence about how a # package construction must be embedded in some file that the # packaging tool uses for input (e.g., debian/rules, debian/control, # debian/changelog; or the RPM specfile), and the precise details are # arbitrary and silly. So this program generates all the relevant # inputs to the packaging tools. # # * Once a .deb or .rpm package is made, there's a separate layer of # tools that makes a "repository" for use by the apt/yum layers of # package tools. The layouts of these repositories are arbitrary and # silly, too. # # * Before you run the program on a new host, these are the # prerequisites: # # apt-get install dpkg-dev rpm debhelper fakeroot ia32-libs createrepo git-core libsnmp15 # echo "Now put the dist gnupg signing keys in ~root/.gnupg" import argparse import errno import getopt from glob import glob from packager import httpget, is_valid_file, ensure_dir, backtick, sysassert, crossproduct import os import re import shutil import stat import subprocess import sys import tempfile import time import urlparse # The MongoDB names for the architectures we support.
