Since Mercurial is commit-oriented, the 'no changes found' message really
should rely on what new commits are in the repo, not on new heads. This also
makes an upcoming patch much simpler.
Since everything around this code is completely broken anyway, writing a test
for this that doesn't trigger other bugs is close to impossible. An upcoming
patch will include tests.
The test output change is for an empty clone -- the output is precisely how
vanilla Mercurial treats an empty clone.
Now that we're in the unified test format, there isn't a need to use echo
to provide context to command output. This technique actually ends up resulting
in redundant output. To preserve the original context, but eliminate the
redundancy, such echo statements have been converted into comment lines.
Mercurial allows specifying which repository to use via the -R/--repository
option. Git allows a similar function using the --git-dir option. By using
these options, in many cases we can avoid checking the current directory.
This makes tests easier to understand, as you don't need to remember which
directory you're in to understand what's going on. It also makes tests easier
to write, as you don't need to remember to cd out of a directory when you're
done doing things there.
Thanks to Felipe Contreras for the patch which this was based on.
One or both of these requirements were in almost every test in exactly the same
way. Now, these checks are performed in every test that uses the testutil.
This makes it easier for test authors to add these checks into new tests (just
add a reference to the testutil, which you'd probably want anyway).
We considered having each test declare their requirements (currently, either
"git" or "dulwich"), but in this case, preferred the simplicity of having the
check always performed (even if a particular test doesn't need one or the
other). You can't perform any meaningful testing of Hg-Git without both of
these dependencies properly configured. The main value to checking for them
in the tests (rather than just letting the tests fail) is that it gives a
meaningful error message to help people figure out how to fix their environment.
In the case that either git or dulwich is missing, the information will be
just as clearly conveyed regardless of whether its all the tests that are
skipped, or just most of them.
I didn't add dulwich to hghave (even though this is clearly the sort of thing
that hghave is intended for) because hghave is currently pulled from Mercurial
completely unchanged, and it's probably best to keep it that way.
Tested by running the tests in three configurations:
* No dulwich installed (ran 0, skipped 28, failed 0, output:
Skipped *: missing feature: dulwich)
* Bad git on path (ran 1, skipped 27, failed 0, output:
Skipped *: missing feature: git command line client)
* Working git and correct version of dulwich installed
(ran 28, skipped 0, failed 0)
Thanks to Felipe Contreras for the idea to extract this logic into a library.
It's functionally equivalent to create a directory, cd into it, git init, and
cd out of the directory, or simply git init with the directory specified.
In several cases, we were doing the former without performing any other
operations in the git repo, which just made the test unneccesarily complex.
Even in the case where we still want to cd into the directory, calling git
init with the directory name eliminates the need for a separate mkdir command.
This changeset converts the former approach to the latter with the goal of
increasing the readability of the tests.

The functions were renamed to make it clearer that these are shell functions
rather than normal git/hg commands, and to make it clearer which tool is being
invoked.
Old name | New name
------------------------
commit | fn_git_commit
tag | fn_git_tag
hgcommit | fn_hg_commit
hgtag | fn_hg_tag
Extraction from test-encoding.t was left for a subsequent patch, as I was seeing
unexpected output changes when I attempted the extraction.
The gitcommit and hgcommit functions in test-bookmark-workflow.t were left
as-is for now, as they have a different behavior than the standard version
(separate counters for each).

Even though the MQ extension was only used in a single test
(test-pull-after-strip.t), I included it in the testutil. It shouldn't hurt
anything to have it enabled and not used, and saves us from having to deal
with enabling extensions in individual tests at all.
Similarly, this changeset results in the graphlog extension being enabled
for all tests, even though there were some that didn't use it before. This is
even less significant in Mercurial 2.3+, since in those versions, graphlog is
part of core, and is available even when the extension is disabled.
