#!/usr/bin/env python # # A script for unpacking and installing different historic versions of # SCons in a consistent manner for side-by-side development testing. # # This abstracts the changes we've made to the SCons setup.py scripts in # different versions so that, no matter what version is specified, it ends # up installing the necessary script(s) and library into version-specific # names that won't interfere with other things. # # By default, we expect to extract the .tar.gz files from a Downloads # subdirectory in the current directory. # # Note that this script cleans up after itself, removing the extracted # directory in which we do the build. # # This was written for a Linux system (specifically Ubuntu) but should # be reasonably generic to any POSIX-style system with a /usr/local # hierarchy. import getopt import os import shutil import sys import tarfile from urllib.request import urlretrieve from Command import CommandRunner, Usage all_versions = [ '0.01', '0.02', '0.03', '0.04', '0.05', '0.06', '0.07', '0.08', '0.09', '0.10', '0.11', '0.12', '0.13', '0.14', '0.90', '0.91', '0.92', '0.93', '0.94', #'0.94.1', '0.95', #'0.95.1', '0.96', '0.96.1', '0.96.90', '0.96.91', '0.96.92', '0.96.93', '0.96.94', '0.96.95', '0.96.96', '0.97', '0.97.0d20070809', '0.97.0d20070918', '0.97.0d20071212', '0.98.0', '0.98.1', '0.98.2', '0.98.3', '0.98.4', '0.98.5', '1.0.0', '1.0.0.d20080826', '1.0.1', '1.0.1.d20080915', '1.0.1.d20081001', '1.1.0', '1.1.0.d20081104', '1.1.0.d20081125', '1.1.0.d20081207', '1.2.0', '1.2.0.d20090113', '1.2.0.d20090223', '1.2.0.d20090905', '1.2.0.d20090919', '1.2.0.d20091224', '1.2.0.d20100117', '1.2.0.d20100306', '1.3.0', '1.3.0.d20100404', '1.3.0.d20100501', '1.3.0.d20100523', '1.3.0.d20100606', '2.0.0.alpha.20100508', '2.0.0.beta.20100531', '2.0.0.beta.20100605', '2.0.0.final.0', ] def main(argv=None): if argv is None: argv = sys.argv all = False downloads_dir = 'Downloads' downloads_url = 'http://downloads.sourceforge.net/scons' if sys.platform == 'win32': sudo = '' prefix = sys.prefix else: sudo = 'sudo' prefix = '/usr/local' python = sys.executable short_options = 'ad:hnp:q' long_options = ['all', 'help', 'no-exec', 'prefix=', 'quiet'] helpstr = """\ Usage: install_scons.py [-ahnq] [-d DIR] [-p PREFIX] [VERSION ...] -a, --all Install all SCons versions. -d DIR, --downloads=DIR Downloads directory. -h, --help Print this help and exit -n, --no-exec No execute, just print command lines -p PREFIX, --prefix=PREFIX Installation prefix. -q, --quiet Quiet, don't print command lines """ try: try: opts, args = getopt.getopt(argv[1:], short_options, long_options) except getopt.error as msg: raise Usage(msg) for o, a in opts: if o in ('-a', '--all'): all = True elif o in ('-d', '--downloads'): downloads_dir = a elif o in ('-h', '--help'): print(helpstr) sys.exit(0) elif o in ('-n', '--no-exec'): CommandRunner.execute = CommandRunner.do_not_execute elif o in ('-p', '--prefix'): prefix = a elif o in ('-q', '--quiet'): CommandRunner.display = CommandRunner.do_not_display except Usage as err: sys.stderr.write(str(err.msg) + '\n') sys.stderr.write('use -h to get help\n') return 2 if all: if args: msg = 'install-scons.py: -a and version arguments both specified' sys.stderr.write(msg) sys.exit(1) args = all_versions cmd = CommandRunner() for version in args: scons = 'scons-' + version tar_gz = os.path.join(downloads_dir, scons + '.tar.gz') tar_gz_url = "%s/%s.tar.gz" % (downloads_url, scons) cmd.subst_dictionary(locals()) if not os.path.exists(tar_gz): if not os.path.exists(downloads_dir): cmd.run('mkdir %(downloads_dir)s') cmd.run((urlretrieve, tar_gz_url, tar_gz), 'wget -O %(tar_gz)s %(tar_gz_url)s') def extract(tar_gz): tarfile.open(tar_gz, "r:gz").extractall() cmd.run((extract, tar_gz), 'tar zxf %(tar_gz)s') cmd.run('cd %(scons)s') if version in ('0.01', '0.02', '0.03', '0.04', '0.05', '0.06', '0.07', '0.08', '0.09', '0.10'): # 0.01 through 0.10 install /usr/local/bin/scons and # /usr/local/lib/scons.
