If we are given an empty pickaxe needle like "git log -S ''",
it is impossible for us to find anything (because no matter
what the content, the count will always be 0). We currently
check this at the lowest level of contains(). Let's hoist
the logic much earlier to has_changes(), so that it is
simpler to return our answer before loading any blob data.

If you use "-G" to grep a diff, we will apply a configured
textconv filter to the data before generating the diff.
However, if the diff is an addition or deletion, we do not
bother running the diff at all, and just look for the token
in the added (or removed) content. This works because we
know that the diff must contain every line of content.
However, while we used the textconv-derived buffers in the
regular diff, we accidentally passed the original unmodified
buffers to regexec when checking the added or removed
content. This could lead to an incorrect answer.
Worse, in some cases we might have a textconv buffer but no
original buffer (e.g., if we pulled the textconv data from
cache, or if we reused a working tree file when generating
it). In that case, we could actually feed NULL to regexec
and segfault.

The git-config command has always implemented its own file
lookup and parsing order. This was necessary because its
duplicate-entry handling did not match the way git's
internal callbacks worked. Now that this is no longer the
case, we are free to reuse the existing parsing code.
This saves us a few lines of code, but most importantly, it
means that the logic for which files are examined is
contained only in one place and cannot diverge.
Signed-off-by: Jeff King <peff@peff.net>
If git-config is asked for a single value, it will complain
and exit with an error if it finds multiple instances of
that value. This is unlike the usual internal config
parsing, however, which will generally overwrite previous
values, leaving only the final one. For example:
[set a multivar]
$ git config user.email one@example.com
$ git config --add user.email two@example.com
[use the internal parser to fetch it]
$ git var GIT_AUTHOR_IDENT
Your Name <two@example.com> ...
[use git-config to fetch it]
$ git config user.email
one@example.com
error: More than one value for the key user.email: two@example.com
This overwriting behavior is critical for the regular
parser, which starts with the lowest-priority file (e.g.,
/etc/gitconfig) and proceeds to the highest-priority file
($GIT_DIR/config). Overwriting yields the highest priority
value at the end.
Git-config solves this problem by implementing its own
parsing. It goes from highest to lowest priorty, but does
not proceed to the next file if it has seen a value.
So in practice, this distinction never mattered much,
because it only triggered for values in the same file. And
there was not much point in doing that; the real value is in
overwriting values from lower-priority files.
However, this changed with the implementation of config
include files. Now we might see an include overriding a
value from the parent file, which is a sensible thing to do,
but git-config will flag as a duplication.
This patch drops the duplicate detection for git-config and
switches to a pure-overwrite model (for the single case;
--get-all can still be used if callers want to do something
more fancy).
As is shown by the modifications to the test suite, this is
a user-visible change in behavior. An alternative would be
to just change the include case, but this is much cleaner
for a few reasons:
1. If you change the include case, then to what? If you
just stop parsing includes after getting a value, then
you will get a _different_ answer than the regular
config parser (you'll get the first value instead of
the last value). So you'd want to implement overwrite
semantics anyway.
2. Even though it is a change in behavior for git-config,
it is bringing us in line with what the internal
parsers already do.
3. The file-order reimplementation is the only thing
keeping us from sharing more code with the internal
config parser, which will help keep differences to a
minimum.
Going under the assumption that the primary purpose of
git-config is to behave identically to how git's internal
parsing works, this change can be seen as a bug-fix.

This is a refactor that will allow us to more easily tweak
the behavior for multi-valued variables, and it will
ultimately allow us to remove a lot git-config's custom code
in favor of the regular git_config code.
It does mean we're no longer streaming, and we're storing
more in memory for the --get-all case, but in practice it is
a tiny amount of data, and the results are instantaneous.

The get_value function has a goto label for cleaning up on
errors, but it only cleans up half of what the function
might allocate. Let's also clean up the key and regexp
variables there.
Note that we need to take special care when compiling the
regex fails to clean it up ourselves, since it is in a
half-constructed state (we would want to free it, but not
regfree it).
Similarly, we fix git_config_parse_key to return NULL when
it fails, not a pointer to some already-freed memory.

The t1300 test script is quite old, and does not use our
modern techniques or styles. This patch updates it in the
following ways:
1. Use test_cmp instead of cmp (to make failures easier to
debug).
2. Use test_cmp instead of 'test $(command) = expected'.
This makes failures much easier to debug, and also
makes sure that $(command) exits appropriately.
3. Use test_must_fail (easier to read, and checks more
rigorously for signal death).
4. Write tests with the usual style of:
test_expect_success 'test name' '
test commands &&
...
'
rather than one-liners, or using backslash-continuation.
This is purely a style fixup.
There are still a few command happening outside of
test_expect invocations, but they are all innoccuous system
commands like "cat" and "cp". In an ideal world, each test
would be self sufficient and all commands would happen
inside test_expect, but it is not immediately obvious how
the grouping should work (some of the commands impact the
subsequent tests, and some of them are setting up and
modifying state that many tests depend on). This patch just
picks the low-hanging style fruit, and we can do more fixes
on top later.

When configured not to use themed widgets gitk may crash on launch with
a message that says that the image "bm-left disabled bm-left-gray"
doesn't exist. This happens when the left and right arrow buttons are
created.
The crash can be avoided by configuring the buttons differently
depending on whether or not themed widgets are used. If themed widgets
are not used then only set the images to bm-left and bm-right
respectively, and keep the old behavior when themed widgets are used.
The previous behaviour was added in f062e50f to work around a bug in Tk
on OS X where the disabled state did not display properly. The buttons
may still not display correctly, however the workaround added in
f062e50f will still apply if gitk is used with themed widgets.
