"""Find tests that newly pass under Python 3. The approach is simple: we maintain a whitelist of Python 3 passing tests in the repository, and periodically run all the /other/ tests and look for new passes. Any newly passing tests get automatically added to the whitelist. You probably want to run it like this: $ cd tests $ python3 ../contrib/python3-ratchet.py \ > --working-tests=../contrib/python3-whitelist """ from __future__ import print_function from __future__ import absolute_import import argparse import json import os import subprocess import sys _hgenv = dict(os.environ) _hgenv.update( { 'HGPLAIN': '1', } ) _HG_FIRST_CHANGE = '9117c6561b0bd7792fa13b50d28239d51b78e51f' def _runhg(*args): return subprocess.check_output(args, env=_hgenv) def _is_hg_repo(path): return ( _runhg('hg', 'log', '-R', path, '-r0', '--template={node}').strip() == _HG_FIRST_CHANGE ) def _py3default(): if sys.version_info[0] >= 3: return sys.executable return 'python3' def main(argv=()): p = argparse.ArgumentParser() p.add_argument( '--working-tests', help='List of tests that already work in Python 3.' ) p.add_argument( '--commit-to-repo', help='If set, commit newly fixed tests to the given repo', ) p.add_argument( '-j', default=os.sysconf('SC_NPROCESSORS_ONLN'), type=int, help='Number of parallel tests to run.', ) p.add_argument( '--python3', default=_py3default(), help='python3 interpreter to use for test run', ) p.add_argument( '--commit-user', default='python3-ratchet@mercurial-scm.org', help='Username to specify when committing to a repo.', ) opts = p.parse_args(argv) if opts.commit_to_repo: if not _is_hg_repo(opts.commit_to_repo): print('abort: specified repository is not the hg repository') sys.exit(1) if not opts.working_tests or not os.path.isfile(opts.working_tests): print( 'abort: --working-tests must exist and be a file (got %r)' % opts.working_tests ) sys.exit(1) elif opts.commit_to_repo: root = _runhg('hg', 'root').strip() if not opts.working_tests.startswith(root): print( 'abort: if --commit-to-repo is given, ' '--working-tests must be from that repo' ) sys.exit(1) try: subprocess.check_call( [ opts.python3, '-c', 'import sys ; ' 'assert ((3, 5) <= sys.version_info < (3, 6) ' 'or sys.version_info >= (3, 6, 2))', ] ) except subprocess.CalledProcessError: print( 'warning: Python 3.6.0 and 3.6.1 have ' 'a bug which breaks Mercurial' ) print('(see https://bugs.python.org/issue29714 for details)') sys.exit(1) rt = subprocess.Popen( [ opts.python3, 'run-tests.py', '-j', str(opts.j), '--blacklist', opts.working_tests, '--json', ] ) rt.wait() with open('report.json') as f: data = f.read() report = json.loads(data.split('=', 1)[1]) newpass = set() for test, result in report.items(): if result['result'] != 'success': continue # A new passing test!
