In tests, call test_cmp rather than raw diff where possible (i.e. if
the output does not go to a pipe), to allow the use of, say, 'cmp'
when the default 'diff -u' is not compatible with a vendor diff.
When that is not possible, use $DIFF, as set in GIT-BUILD-OPTIONS.

In ref_remove_duplicates, when we encounter a duplicate and remove it
from the list we need to make sure that the prev pointer stays
pointing at the last entry and also skip over adding the just freed

Earlier, the rsync tests were disabled by default, as they needed a
running rsyncd daemon. This was only due to the limitation that our
rsync transport only allowed full URLs of the form
rsync://<host>/<path>
Relaxing the URLs to allow
rsync:<path>
permitted the change in the tests to run whenever rsync is available,
without requiring a fully configured and running rsyncd.
While at it, the tests were fixed so that they run in directories with a
space in their name.

* js/maint-fetch-update-head:
pull: allow "git pull origin $something:$current_branch" into an unborn branch
Fix fetch/pull when run without --update-head-ok
Conflicts:
t/t5510-fetch.sh
Some confusing tutorials suggested that it would be a good idea to fetch
into the current branch with something like this:
git fetch origin master:master
(or even worse: the same command line with "pull" instead of "fetch").
While it might make sense to store what you want to pull, it typically is
plain wrong when the current branch is "master". This should only be
allowed when (an incorrect) "git pull origin master:master" tries to work
around by giving --update-head-ok to underlying "git fetch", and otherwise
we should refuse it, but somewhere along the lines we lost that behavior.
The check for the current branch is now _only_ performed in non-bare
repositories, which is an improvement from the original behaviour.
Some newer tests were depending on the broken behaviour of "git fetch"
this patch fixes, and have been adjusted.

match_explicit is called for each push refspec to try to
fully resolve the source and destination sides of the
refspec. Currently, we look at each refspec and report
errors on both the source and the dest side before aborting.
It makes sense to report errors for each refspec, since an
error in one is independent of an error in the other.
However, reporting errors on the 'dst' side of a refspec if
there has been an error on the 'src' side does not
necessarily make sense, since the interpretation of the
'dst' side depends on the 'src' side (for example, when
creating a new unqualified remote ref, we use the same type
as the src ref).
This patch lets match_explicit return early when the src
side of the refspec is bogus. We still look at all of the
refspecs before aborting the push, though.
At the same time, we clean up the call signature, which
previously took an extra "errs" flag. This was pointless, as
we didn't act on that flag, but rather just passed it back
to the caller. Instead, we now use the more traditional
"return -1" to signal an error, and the caller aggregates
the error count.
This change fixes two bugs, as well:
- the early return avoids a segfault when passing a NULL
matched_src to guess_ref()
- the check for multiple sources pointing to a single dest
aborted if the "err" flag was set. Presumably the intent
was not to bother with the check if we had no
matched_src. However, since the err flag was passed in
from the caller, we might abort the check just because a
previous refspec had a problem, which doesn't make
sense.
In practice, this didn't matter, since due to the error
flag we end up aborting the push anyway.

Many scripts compare actual and expected output using
"diff -u". This is nicer than "cmp" because the output shows
how the two differ. However, not all versions of diff
understand -u, leading to unnecessary test failure.
This adds a test_cmp function to the test scripts and
switches all "diff -u" invocations to use it. The function
uses the contents of "$GIT_TEST_CMP" to compare its
arguments; the default is "diff -u".
On systems with a less-capable diff, you can do:
GIT_TEST_CMP=cmp make test

Originally, test_expect_failure was designed to be the opposite
of test_expect_success, but this was a bad decision. Most tests
run a series of commands that leads to the single command that
needs to be tested, like this:
test_expect_{success,failure} 'test title' '
setup1 &&
setup2 &&
setup3 &&
what is to be tested
'
And expecting a failure exit from the whole sequence misses the
point of writing tests. Your setup$N that are supposed to
succeed may have failed without even reaching what you are
trying to test. The only valid use of test_expect_failure is to
check a trivial single command that is expected to fail, which
is a minority in tests of Porcelain-ish commands.
This large-ish patch rewrites all uses of test_expect_failure to
use test_expect_success and rewrites the condition of what is
tested, like this:
test_expect_success 'test title' '
setup1 &&
setup2 &&
setup3 &&
! this command should fail
'
test_expect_failure is redefined to serve as a reminder that
that test *should* succeed but due to a known breakage in git it
currently does not pass. So if git-foo command should create a
file 'bar' but you discovered a bug that it doesn't, you can
write a test like this:
test_expect_failure 'git-foo should create bar' '
rm -f bar &&
git foo &&
test -f bar
'
This construct acts similar to test_expect_success, but instead
of reporting "ok/FAIL" like test_expect_success does, the
outcome is reported as "FIXED/still broken".

The old rules used by fetch were coded as a series of ifs. The old
rules are:
1) match full refname if it starts with "refs/" or matches "HEAD"
2) verify that full refname starts with "refs/"
3) match abbreviated name in "refs/" if it starts with "heads/",
"tags/", or "remotes/".
4) match abbreviated name in "refs/heads/"
This is replaced by the new rules
a) match full refname
b) match abbreviated name prefixed with "refs/"
c) match abbreviated name prefixed with "refs/heads/"
The details of the new rules are different from the old rules. We no
longer verify that the full refname starts with "refs/". The new rule
(a) matches any full string. The old rules (1) and (2) were stricter.
Now, the caller is responsible for using sensible full refnames. This
should be the case for the current code. The new rule (b) is less
strict than old rule (3). The new rule accepts abbreviated names that
start with a non-standard prefix below "refs/".
Despite this modifications the new rules should handle all cases as
expected. Two tests are added to verify that fetch does not resolve
short tags or HEAD in remotes.
We may even think about loosening the rules a bit more and unify them
with the rev-parse rules. This would be done by replacing
ref_ref_fetch_rules with ref_ref_parse_rules. Note, the two new test
would break.

Also, add a test to t5510. Since rsync transport is not configured by
default on most machines, and especially not such that you can write to
rsync://127.0.0.1$(pwd)/, it is disabled by default; you can enable it by

Some workflows require use of repositories on machines that cannot be
connected, preventing use of git-fetch / git-push to transport objects and
references between the repositories.
git-bundle provides an alternate transport mechanism, effectively allowing
git-fetch and git-pull to operate using sneakernet transport. `git-bundle
create` allows the user to create a bundle containing one or more branches
or tags, but with specified basis assumed to exist on the target
repository. At the receiving end, git-bundle acts like git-fetch-pack,
allowing the user to invoke git-fetch or git-pull using the bundle file as
the URL. git-fetch and git-ls-remote determine they have a bundle URL by
checking that the URL points to a file, but are otherwise unchanged in
operation with bundles.
The original patch was done by Mark Levedahl <mdl123@verizon.net>.
It was updated to make git-bundle a builtin, and get rid of the tar
format: now, the first line is supposed to say "# v2 git bundle", the next
lines either contain a prerequisite ("-" followed by the hash of the
needed commit), or a ref (the hash of a commit, followed by the name of
the ref), and finally the pack. As a result, the bundle argument can be
"-" now.
