rhg: use `Command::exec` instead of `Command::status`
`rhg` is supposed to be a transparent executable, using a subprocess defeats
that purpose. See inline comments for more details.
This also introduces the `which` crate to check if the fallback executable
actually exists to help debugging (plain `execve` doesn't give much
information).
The error code 253 is used to signify that the fallback is not found, but may
mean in the future that it is otherwise invalid if we start being more
specific.

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.
