typing: add trivial type hints to the convert extension's common modules
This started as ensuring that the `encoding` and `orig_encoding` attributes has
a type other than `Any`, so pytype can catch problems where it needs to be str
for stdlib encoding and decoding. It turns out that adding the hint in
`mercurial.encoding` is what was needed, but I picked a bunch of low hanging
fruit while here. There's definitely more to do, and I see a problem where
`shlex.shlex` is being fed bytes instead of str, but there are not enough type
hints yet to make pytype notice.

A python hook for "hg fix" that prints out the number of files and revisions that were affected, along with which fixer tools were applied. Also checks how many times it sees a specific key generated by one of the fixer tools defined below. $ cat >> $TESTTMP/postfixhook.py <<EOF > import collections > def file(ui, repo, rev=None, path=b'', metadata=None, **kwargs): > ui.status(b'fixed %s in revision %d using %s\n' % > (path, rev, b', '.join(metadata.keys()))) > def summarize(ui, repo, replacements=None, wdirwritten=False, > metadata=None, **kwargs): > counts = collections.defaultdict(int) > keys = 0 > for fixername, metadatalist in metadata.items(): > for metadata in metadatalist: > if metadata is None: > continue > counts[fixername] += 1 > if 'key' in metadata: > keys += 1 > ui.status(b'saw "key" %d times\n' % (keys,)) > for name, count in sorted(counts.items()): > ui.status(b'fixed %d files with %s\n' % (count, name)) > if replacements: > ui.status(b'fixed %d revisions\n' % (len(replacements),)) > if wdirwritten: > ui.status(b'fixed the working copy\n') > EOF Some mock output for fixer tools that demonstrate what could go wrong with expecting the metadata output format. $ printf 'new content\n' > $TESTTMP/missing $ printf 'not valid json\0new content\n' > $TESTTMP/invalid $ printf '{"key": "value"}\0new content\n' > $TESTTMP/valid Configure some fixer tools based on the output defined above, and enable the hooks defined above.
