At one time we used the local pushlog, + which required the mozext hg extension. This isn't feasible with git, and it + is only mildly less efficient to not use the pushlog, so we don't use it even + when querying hg. + +* map the candidate parent to candidate Task Cluster tasks and artifact + locations. Pushlog entries might not correspond to tasks (yet), and those + tasks might not produce the desired class of artifacts. + +* fetch fresh Task Cluster artifacts and purge old artifacts, using a simple + Least Recently Used cache. + +* post-process fresh artifacts, to speed future installation. In particular, + extract relevant files from Mac OS X DMG files into a friendly archive format + so we don't have to mount DMG files frequently. + +This module requires certain modules be importable from the ambient Python +environment. |mach artifact| ensures these modules are available, but other +consumers will need to arrange this themselves. +""" + + +import collections +import functools +import glob +import logging +import operator +import os +import pickle +import re +import shutil +import stat +import subprocess +import tarfile +import tempfile +import zipfile +from contextlib import contextmanager +from io import BufferedReader +from urllib.parse import urlparse + +import buildconfig +import mozinstall +import mozpack.path as mozpath +import pylru +import requests +import six +from mach.util import UserError +from mozpack import executables +from mozpack.files import JarFinder, TarFinder +from mozpack.mozjar import JarReader, JarWriter +from mozpack.packager.unpack import UnpackFinder +from taskgraph.util.taskcluster import find_task_id, get_artifact_url, list_artifacts + +from mozbuild.artifact_builds import JOB_CHOICES +from mozbuild.artifact_cache import ArtifactCache +from mozbuild.util import FileAvoidWrite, ensureParentDir, mkdir + +# Number of candidate pushheads to cache per parent changeset. +NUM_PUSHHEADS_TO_QUERY_PER_PARENT = 50 + +# Number of parent changesets to consider as possible pushheads. +# There isn't really such a thing as a reasonable default here, because we don't +# know how many pushheads we'll need to look at to find a build with our artifacts, +# and we don't know how many changesets will be in each push.
