rust-cpython: make inner functions and structs of ref_sharing private
Most of these methods were public because they had to be accessible from
macro-generated functions. Some "unsafe" can be removed since we can
guarantee the data consistency across non-public operations.
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. Disable parallelism to make output of the parallel file
processing phase stable.

See what happens when we execute each of the fixer tools. Some print warnings,
some write back to the file.
