import-checker: loop to get list of locally defined modules at first This is a preparation for subsequent patches, which expect that all locally defined (= mercurial specific) modules are already known before examinations. Looping twice for specified modules is a little redundant, but reasonable cost for improvement in subsequent patches.

import-checker: add xargs like mode Before this patch, "import-check.py" is invoked via "xargs" in "test-module-imports.t", but it doesn't ensure that "import-checker.py" is certainly invoked with all mercurial specific files at once. "xargs" may invoke specified command multiple times with part of arguments given from stdin: according to "xargs(1)" man page, this dividing arguments is system-dependent. This patch adds "xargs" like mode to "import-checker.py". This can ensure that "import-checker.py" is certainly invoked with all mercurial specific files at once in "test-module-imports.t". This is assumed by subsequent patches.

store: add comment in _hashencode with reason for skipping the first 5 chars

test-run-tests: fix for Python 3.5 This test now passes in both 3.5 and 2.6.

run-tests: make sure all script lines are bytes

run-tests: fix checking a line to see if it needs globbing

run-tests: unblock running python tests in python 3 This makes it clear we need to ban os.popen, but we'll do that in a later cleanup.

run-tests: os.popen returns a string, make it bytes again

run-tests: be more paranoid about os.system using bytes

run-tests: blacklist entries are bytes, use bname to check blacklisting

test-run-tests.t: work around file.write() returning an int In Python 3.5, file.write() returns the number of bytes it wrote instead of None.

run-tests: write bytes to the binary buffer on sys.{stdout,stderr}

run-tests: record faildata using bytes instead of str lines is already bytes, so this is just fixing a bug on python 3.

run-tests: do cdata escaping using bytes instead of str

run-tests: make sure keyword(s) are in bytes and not str

run-tests: use items instead of iteritems on dicts This works the same-enough on 2.6 and 3.5 to be fine.

run-tests: refer to test.bname when sniffing for keywords

run-tests: string-escape no longer exists in python 3, use unicode_escape

run-tests: switch all uses of iolock.acquire() to a context manager

run-tests: use difflib.diff_bytes on Python 3 This method was introduced in Python 3.5 to satisfy our diffing-strings-of-bytes needs.

run-tests: fix installation of hg by bytesifying more constants

setup: decode xcode version number on python3

run-tests: work around with_hg being bytes or string depending on provenance

run-tests: even more bytestring annotations for Python 3

run-tests: write bytes to sys.stdout.buffer in python 3

run-tests: be more judicious about bytes vs string on test attrs This introduces a bname attribute for when we need to use the test name in a path, and retains name for when we need it as a string. Sadly, we seem to need both of these.

run-tests: fix _findprogram to reliably return bytes

run-tests: introduce a name for os.environb On python 2 this is just os.environ, but on python 3 we need to get to os.environb in several places.
