py3: use email parser that operates on bytes email.parser.Parser() operates on str in both Python 2 and 3. Python 3.2 introduced the email.parser.BytesParser(), which works like Parser except it accepts bytes. We implement the pycompat helper as a function so we lazily import the "email" module.

py3: port ext-phase-report.py extension The custom module importer doesn't run on Python files in the tests directory. So we need the source to be compatible with both Python 2 and 3. Differential Revision: https://phab.mercurial-scm.org/D2145

py3: more robustly cast UUID to bytes The UUID type only has __str__ implemented. So we need to cast to bytes on Python 3. We need an actual bytes instance here (bytestr won't do) because the re.escape() later iterates over characters and characters need to behave like ints, not bytes instances of length 1. Differential Revision: https://phab.mercurial-scm.org/D2144

py3: use bytes() to cast context instances __str__ and __bytes__ are both implemented on context types. However, __str__ behaves differently on Python 2 and 3. Differential Revision: https://phab.mercurial-scm.org/D2143

run-tests: report tests that exception occurred in We now record the test that an exception occurred in. We put this information to use by aggregating the count of failures in each test. For each exception, the exception report now prints the total number of tests having that exception and the test with the least number of exceptions exhibiting that failure. The exception list is now sorted by (total count, tests impacted, count of failures in least failing test). This allows us to: * Assess how widespread a failure is. Some exceptions occur a lot in a few tests. Others occur over many tests. * Easily run a test exhibiting an exception without having to find a failure in test output. * Find and fix low hanging fruit (e.g. exceptions that are the only failure in a test). Here's an example of the new output: 199 (4 tests) /home/gps/src/hg/hgext/blackbox.py:191: %b requires a bytes-like object, or an object that implements __bytes__, not 'str' (test-devel-warnings.t - 1 total) 142 (19 tests) /home/gps/src/hg/hgext/mq.py:655: list indices must be integers or slices, not bytes (test-hardlinks.t - 1 total) 140 (20 tests) /home/gps/src/hg/mercurial/patch.py:296: string argument expected, got 'bytes' (test-audit-subrepo.t - 1 total) 101 (15 tests) /home/gps/src/hg/hgext/convert/convcmd.py:60: encode() argument 1 must be str, not bytes (test-convert-clonebranches.t - 1 total) 90 (2 tests) /home/gps/src/hg/hgext/mq.py:456: can't concat str to bytes (test-mq-qqueue.t - 1 total) 87 (2 tests) /home/gps/src/hg/mercurial/branchmap.py:380: %b requires a bytes-like object, or an object that implements __bytes__, not 'FileNotFoundError' (test-branches.t - 2 total) 85 (22 tests) /home/gps/src/hg/mercurial/sshpeer.py:223: cannot convert 'UUID' object to bytes (test-bundle2-pushback.t - 1 total) 1 (1 tests) /home/gps/src/hg/mercurial/formatter.py:254: %b requires a bytes-like object, or an object that implements __bytes__, not 'str' (test-debugextensions.t - 2 total) 1 (1 tests) /home/gps/src/hg/hgext/convert/convcmd.py:420: startswith first arg must be str or a tuple of str, not bytes (test-convert-authormap.t - 2 total) 1 (1 tests) /home/gps/src/hg/mercurial/revlog.py:797: '>=' not supported between instances of 'NoneType' and 'int' (test-unionrepo.t - 1 total) 1 (1 tests) /home/gps/src/hg/hgext/show.py:129: %b requires a bytes-like object, or an object that implements __bytes__, not 'str' (test-show.t - 1 total) Differential Revision: https://phab.mercurial-scm.org/D2138

py3: use raw string for file open mode Otherwise the module importer rewrites it to bytes on Python 3, which angers Python 3. Differential Revision: https://phab.mercurial-scm.org/D2137

py3: convert content-type to bytes This fixes the exception: TypeError: %b requires a bytes-like object, or an object that implements __bytes__, not 'str' On the line: ui.debug('Content-Type: %s\n' % content_type) And it prevents additional exceptions that use the content_type variable later.

gpg: print unknown key IDs in their entirety Shortening the key is nice in theory but it results in ambiguity which can be exploited. Therefore, when encountering an unknown key ID we should print the whole ID returned by gpg. This may or may not be the whole key, however it will match the user preference set in gpg configuration. Furthermore, the key ID shortening had a couple of issues: (1) it truncated the key ID (dropping the last digit and outputting only 15 hex digits) making it very hard to find the correct key on a key server (2) since only 15 digits were fed into shortkey(), it always emitted the ui.debug() warning

tests: fix check for --graph option in test-log-linerange.t Previous test about incompatibility of --line-range and --graph options was problematic because, even without --graph option, the command would have failed because specified path (dir/baz) did not exist as it got dropped in previous test statements. New test statements should work without --graph. This prepares for making --line-range compatible with --graph option.
