A command exiting with the expected status is not particularly
notable.
While the indication of progress might be useful when tracking down
where in a test a failure has happened, the same applies to most other
test helpers, which are quiet about success, so this single helper's
output stands out in an unpleasant way. An alternative method for
showing progress information might to invent a --progress option that
runs tests with "set -x", or until that is available, to run tests
using commands like
prove -v -j2 --shuffle --exec='sh -x' t2202-add-addremove.sh

Accept

as an alternative to a more common style that introduces perl
functions with a brace on the first line (and likewise for BEGIN/END
blocks). The new regex is a little hairy to avoid matching
# forward declaration
sub foo;
while continuing to match "sub foo($;@) {" and
sub foo { # This routine is interesting;
# in fact, the lines below explain how...
While at it, pay attention to Perl 5.14's "package foo {" syntax as an
alternative to the traditional "package foo;".

The builtin perl userdiff driver is not greedy enough about catching
POD header lines. Capture the whole line, so instead of just
declaring that we are in some "@@ =head1" section, diff/grep output
can explain that the enclosing section is about "@@ =head1 OPTIONS".

The userdiff funcname mechanism has no concept of nested scopes ---
instead, "git diff" and "git grep --show-function" simply label the
diff header with the most recent matching line. Unfortunately that
means text following a subroutine in a POD section:
=head1 DESCRIPTION
You might use this facility like so:
sub example {
foo;
}
Now, having said that, let's say more about the facility.
Blah blah blah ... etc etc.
gets the subroutine name instead of the POD header in its diff/grep
funcname header, making it harder to get oriented when reading a
diff without enough context.
The fix is simple: anchor the funcname syntax to the left margin so
nested subroutines and packages like this won't get picked up. (The
builtin C++ funcname pattern already does the same thing.) This means
the userdiff driver will misparse the idiom
{
my $static;
sub foo {
... use $static ...
}
}
but I think that's worth it; we can revisit this later if the userdiff
mechanism learns to keep track of the beginning and end of nested
scopes.

Introduce a test_expect_funcname function to make a diff and apply a
regexp anchored on the left to the function name it writes, avoiding
some repetition.
Omit the space after >, <<, and < operators for consistency with
other scripts. Quote the <<here document delimiter and $ signs in
quotes so readers don't have to worry about the effect of shell
metacharacters.
Remove some unnecessary blank lines.
Run "git diff" as a separate command instead of as upstream of a pipe
that checks its output, so the exit status can be tested. In
particular, this way if "git diff" starts segfaulting the test harness
will notice.
Allow "error:" as a synonym for "fatal:" when checking error messages,
since whether a command uses die() or "return error()" is a small
implementation detail.
Anchor some more regexes on the right.
None of the above is very important on its own; the point is just to
make the script a little easier to read and the code less scary to
modify.

Introduce a "test_config" function to set a configuration variable
for use by a single test (automatically unsetting it when the
assertion finishes). If this function is used consistently, the
configuration used in a test_expect_success block can be read at the
beginning of that block instead of requiring reading all the tests
that come before. So it becomes a little easier to add new tests or
rearrange existing ones without fear of breaking configuration.
In particular, the test of alternation in xfuncname patterns also
checks that xfuncname takes precedence over funcname variable as a
sort of side-effect, since the latter leaks in from previous tests.
In the new syntax, the test has to say explicitly what variables it is
using, making the test clearer and a future regression in coverage
from carelessly editing the script less likely.

Most, but not all, tests in this script rely on attributes declaring
that files with a .java extension should use the "java" driver:
*.java diff=java
Split out a "set up" test to put such a .gitattributes in place after
the tests that do not want it have run, to make it more likely that
individual tests other than this setup test can be safely modified,
rearranged, or skipped. Presumably this setup code will learn to
request other drivers for other extensions in the same place when the
test suite learns to exercise other diff drivers.
Similarly, make sure that early test assertions that do not use these
default attributes set up .gitattributes appropriately for themselves,
so tests that run before can be modified with less risk of breaking
something.

With diff.suppress-blank-empty=true, "git diff --word-diff" would
output data that had been read from uninitialized heap memory.
The problem was that fn_out_consume did not account for the
possibility of a line with length 1, i.e., the empty context line
that diff.suppress-blank-empty=true converts from " \n" to "\n".
Since it assumed there would always be a prefix character (the space),
it decremented "len" unconditionally, thus passing len=0 to emit_line,
which would then blindly call emit_line_0 with len=-1 which would
pass that value on to fwrite as SIZE_MAX. Boom.

As the band-aid to merge-recursive seems to regress complex merges in an
unpleasant way. The merge-recursive implementation needs to be rewritten
in such a way that it resolves renames and D/F conflicts entirely in-core
and not to touch working tree at all while doing so. But in the meantime,
this reverts commit ac9666f84 that merged the topic in its entirety.
When receiving a push, we advertise ref tips from any
alternate repositories, in case that helps the client send a
smaller pack. Since these refs don't actually exist in the
destination repository, we don't transmit the real ref
names, but instead use the pseudo-ref ".have".
If your alternate has a large number of duplicate refs (for
example, because it is aggregating objects from many related
repositories, some of which will have the same tags and
branch tips), then we will send each ".have $sha1" line
multiple times. This is a pointless waste of bandwidth, as
we are simply repeating the same fact to the client over and
over.
This patch eliminates duplicate .have refs early on. It does
so efficiently by sorting the complete list and skipping
duplicates. This has the side effect of re-ordering the
.have lines by ascending sha1; this isn't a problem, though,
as the original order was meaningless.
There is a similar .have system in fetch-pack, but it
does not suffer from the same problem. For each alternate
ref we consider in fetch-pack, we actually open the object
and mark it with the SEEN flag, so duplicates are
automatically culled.

The foreach_alt_odb function triggers a callback for each
alternate object db we have, with room for a single void
pointer as data. Currently, we always call refs_from_alternate_cb
as the callback function, and then pass another callback (to
receive each ref individually) as the void pointer.
This has two problems:
1. C technically forbids stuffing a function pointer into
a "void *". In practice, this probably doesn't matter
on any architectures git runs on, but it never hurts to
follow the letter of the law.
2. There is no room for an extra data pointer. Indeed, the
alternate_ref_fn that refs_from_alternate_cb calls
takes a void* for data, but we always pass it NULL.
Instead, let's properly stuff our function pointer into a
data struct, which also leaves room for an extra
caller-supplied data pointer. And to keep things simple for
existing callers, let's make a for_each_alternate_ref
function that takes care of creating the extra struct.

We add every local ref to a list so that we can mark them
and all of their ancestors back to a certain cutoff point.
However, if some refs point to the same commit, we will end
up adding them to the list many times.
Furthermore, since commit_lists are stored as linked lists,
we must do an O(n) traversal of the list in order to find
the right place to insert each commit. This makes building
the list O(n^2) in the number of refs.
For normal repositories, this isn't a big deal. We have a
few hundreds refs at most, and most of them are unique. But
consider an "alternates" repo that serves as an object
database for many other similar repos. For reachability, it
needs to keep a copy of the refs in each child repo. This
means it may have a large number of refs, many of which
point to the same commits.
By noting commits we have already added to the list, we can
shrink the size of "n" in such a repo to the number of
unique commits, which is on the order of what a normal repo
would contain (it's actually more than a normal repo, since child repos
may have branches at different states, but in practice it tends
to be much smaller than the list with duplicates).
Here are the results on one particular giant repo
(containing objects for all Rails forks on GitHub):

Depending on the application, it is not necessarily an error for an object
to lack a note, especially if the only thing the caller wants to make sure
is that notes are cleared for an object. By passing this option from the

object did not have any note to begin with.

While "xargs -n1 git notes rm" is certainly a possible way to remove notes
from many objects, this would create one notes "commit" per removal, which
is not quite suitable for seasonal housekeeping.
Allow taking more than one on the command line, and record their removal
as a single atomic event if everthing goes well.
Even though the old code insisted that "git notes rm" must be given only
one object (or zero, in which case it would default to HEAD), this
condition was not tested. Add tests to handle the new case where we feed
multiple objects, and also make sure if there is a bad input, no change
is recorded.

talked with the remote repository. A new option "--exit-code" makes the

This way, the caller can tell if we failed to contact the remote, or the

output from the command, which has been and will continue to be a valid
