Because depot_tools expects `python` to be `python2` (shame!), python2 must come before python3 in your path. Upstream: https://chromium.googlesource.com/angle/angle Our repo: https://github.com/mozilla/angle It has branches like 'firefox-60' which is the branch we use for pulling into Gecko with this script. This script leaves a record of the merge-base and cherry-picks that we pull into Gecko. (gfx/angle/cherries.log) ANGLE<->Chrome version mappings are here: https://omahaproxy.appspot.com/ An easy choice is to grab Chrome's Beta's ANGLE branch. ## Usage Prepare your env: ~~~ export PATH="$PATH:/path/to/depot_tools" ~~~ If this is a new repo, don't forget: ~~~ # In the angle repo: ./scripts/bootstrap.py gclient sync ~~~ Update: (in the angle repo) ~~~ # In the angle repo: /path/to/gecko/gfx/angle/update-angle.py origin git push moz # Push the firefox-XX branch to github.com/mozilla/angle ~~~~ """ import json import os import pathlib import re import shutil import subprocess import sys from typing import * # mypy annotations REPO_DIR = pathlib.Path.cwd() GECKO_ANGLE_DIR = pathlib.Path(__file__).parent OUT_DIR = pathlib.Path("out") COMMON_HEADER = [ "# Generated by update-angle.py", "", 'include("../../moz.build.common")', ] ROOTS = ["//:translator", "//:libEGL", "//:libGLESv2"] CHECK_ONLY = False args = sys.argv[1:] while True: arg = args.pop(0) if arg == "--check": CHECK_ONLY = True continue args.insert(0, arg) break GN_ENV = dict(os.environ) GN_ENV["DEPOT_TOOLS_WIN_TOOLCHAIN"] = "0" (GIT_REMOTE,) = args # Not always 'origin'! # ------------------------------------------------------------------------------ def run_checked(*args, **kwargs): print(" ", args) sys.stdout.flush() return subprocess.run(args, check=True, **kwargs) def sorted_items(x): for k in sorted(x.keys()): yield (k, x[k]) def collapse_dotdots(path): split = path.split("/") ret = [] for x in split: if x == ".." and ret: ret.pop() continue ret.append(x) continue return "/".join(ret) def dag_traverse(root_keys: Sequence[str], pre_recurse_func: Callable[[str], list]): visited_keys: Set[str] = set() def recurse(key): if key in visited_keys: return visited_keys.add(key) t = pre_recurse_func(key) try: (next_keys, post_recurse_func) = t except ValueError: (next_keys,) = t post_recurse_func = None for x in next_keys: recurse(x) if post_recurse_func: post_recurse_func(key) return for x in root_keys: recurse(x) return # ------------------------------------------------------------------------------ print("Importing graph") # shutil.rmtree(str(OUT_DIR), True) OUT_DIR.mkdir(exist_ok=True) GN_ARGS = b""" # Build arguments go here. # See "gn args --list" for available build arguments. is_clang = true is_debug = false angle_build_all = false angle_enable_abseil = false angle_enable_apple_translator_workarounds = true angle_enable_essl = true angle_enable_gl = false angle_enable_gl_desktop_frontend = false angle_enable_glsl = true angle_enable_null = false angle_enable_share_context_lock = true angle_enable_vulkan = false angle_has_astc_encoder = false use_custom_libcxx = false """[ 1: ] args_gn_path = OUT_DIR / "args.gn" args_gn_path.write_bytes(GN_ARGS) try: run_checked("gn", "gen", str(OUT_DIR), shell=True, env=GN_ENV) except subprocess.CalledProcessError: sys.stderr.buffer.write(b"`gn` failed.
