perf: use a formatter for output We use a `formatter` object in the perf extensions. This allow the use of formatted output like json. To avoid adding logic to create a formatter and pass it around to the timer function in every command, we add a `gettimer` function in charge of returning a `timer` function as simple as before but embedding an appropriate formatter. This new `gettimer` function also return the formatter as it needs to be explicitly closed at the end of the command. example output: $ hg --config ui.formatjson=True perfvolatilesets visible obsolete [ { "comb": 0.02, "count": 126, "sys": 0.0, "title": "obsolete", "user": 0.02, "wall": 0.0199398994446 }, { "comb": 0.02, "count": 117, "sys": 0.0, "title": "visible", "user": 0.02, "wall": 0.0250301361084 } ]

Systematic behavior validation of most possible cases
=====================================================

This section tests most of the possible combinations of revision states and
working directory states. The number of possible cases is significant but they
but they all have a slightly different handling. So this section commits to
and testing all of them to allow safe refactoring of the revert code.

A python script is used to generate a file history for each combination of
states, on one side the content (or lack thereof) in two revisions, and
on the other side, the content and "tracked-ness" of the working directory. The
three states generated are:

- a "base" revision
- a "parent" revision
- the working directory (based on "parent")

The files generated have names of the form:

 <rev1-content>_<rev2-content>_<working-copy-content>-<tracked-ness>

All known states are not tested yet. See inline documentation for details.
Special cases from merge and rename are not tested by this section.
