Fetching 'frotz' branch with "git fetch", while having
'frotz/nitfol' remote-tracking branch from an earlier fetch, would
error out, primarily because the command has not been told to

can be used to remove 'frotz/nitfol' to make room to fetch and
store 'frotz' remote-tracking branch.

When we have a remote-tracking branch named "frotz/nitfol" from a
previous fetch, and the upstream now has a branch named "frotz",
fetch would fail to remove "frotz/nitfol" with a "git fetch --prune"
from the upstream. git would inform the user to use "git remote
prune" to fix the problem.
Change the way "fetch --prune" works by moving the pruning operation
before the fetching operation. This way, instead of warning the user
of a conflict, it autmatically fixes it.

Having a simulated "known breakage" test means that the test
suite will always tell us there is a bug to be fixed, even
though it is only simulated.
The right way to test this is in a sub-test, that can also
check that we provide the correct exit status and output.
Fortunately, we already have such a test (added much later
by 5ebf89e).
We could arguably get rid of the simulated success test
immediately above, as well, as it is also redundant with the
tests added in 5ebf89e. However, it does not have the
annoying behavior of the "known breakage" test. It may also
be easier to debug if the test suite is truly broken, since
it is not a test-within-a-test, as the later tests are.

Commit 517cd55 set HARNESS_ACTIVE unconditionally in
sub-tests, because that value affects the output of
"--verbose". t0000 needs stable output from its sub-tests,
and we may or may not be running under a TAP harness.
That commit made the decision to always set the variable,
since it has another useful side effect, which is
suppressing writes to t/test-results by the sub-tests (which
would just pollute the real results).
Since the last commit, though, the sub-tests have their own
test-results directories, so this is no longer an issue. We
can now update a few comments that are no longer accurate
nor necessary.
We can also revisit the choice of HARNESS_ACTIVE. Since we
must choose one value for stability, it's probably saner to
have it off. This means that future patches could test
things like the test-results writing, or the "--quiet"
option, which is currently ignored when run under a harness.

Running t0000 produces more trash directories than expected and does
not clean up after itself:
$ ./t0000-basic.sh
[...]
$ ls -d trash\ directory.*
trash directory.failing-cleanup
trash directory.mixed-results1
trash directory.mixed-results2
trash directory.partial-pass
trash directory.test-verbose
trash directory.test-verbose-only-2
These scratch areas for sub-tests should be under the t0000 trash
directory, but because TEST_OUTPUT_DIRECTORY defaults to
TEST_DIRECTORY, which is exported to help sub-tests find
test-lib.sh, the sub-test trash directories are created under the
toplevel t/ directory instead. Because some of the sub-tests
simulate failures, their trash directories are kept around.
Fix it by explicitly setting TEST_OUTPUT_DIRECTORY appropriately for
sub-tests.
An alternative fix would be to pass the --root parameter that only
specifies where to put the trash directories, which would also work.
However, using TEST_OUTPUT_DIRECTORY is more futureproof in case
tests want to write more output in addition to the test-results/
(which are already suppressed in sub-tests using the HARNESS_ACTIVE
setting) and trash directories.
This fixes a regression introduced by 38b074d (t/test-lib.sh: fix
TRASH_DIRECTORY handling, 2013-04-14). Before that commit, the
TEST_OUTPUT_DIRECTORY setting was not respected consistently so most
tests did their work in a "trash" subdirectory of the current
directory instead of the output dir.

The httpd server we set up to test git's http client code
knows about a single account, in which both the username and
password are "user@host" (the unusual use of the "@" here is
to verify that we handle the character correctly when URL
escaped).
This means that we may miss a certain class of errors in
which the username and password are mixed up internally by
git. We can make our tests more robust by having distinct
values for the username and password.
In addition to tweaking the server passwd file and the
client URL, we must teach the "askpass" harness to accept
multiple values. As a bonus, this makes the setup of some
tests more obvious; when we are expecting git to ask
only about the password, we can seed the username askpass
response with a bogus value.

We might want to vet the existing callers of the underlying
get_octopus_merge_bases() and find out if _all_ of them are doing
anything extra (like deduping) because the machinery can return
duplicate results. And if that is the case, then we may want to
move the dedupling down the callchain instead of having it here.

Support for grafts predates Git's strbuf, and hence it is understandable
that there was a hard-coded line length limit of 1023 characters (which
was chosen a bit awkwardly, given that it is *exactly* one byte short of
aligning with the 41 bytes occupied by a commit name and the following
space or new-line character).
While regular commit histories hardly win comprehensibility in general
if they merge more than twenty-two branches in one go, it is not Git's
business to limit grafts in such a way.
In this particular developer's case, the use case that requires
substantially longer graft lines to be supported is the visualization of
the commits' order implied by their changes: commits are considered to
have an implicit relationship iff exchanging them in an interactive
rebase would result in merge conflicts.
Thusly implied branches tend to be very shallow in general, and the
resulting thicket of implied branches is usually very wide; It is
actually quite common that *most* of the commits in a topic branch have
not even one implied parent, so that a final merge commit has about as
many implied parents as there are commits in said branch.

Two packfiles that contain the same set of objects have

It can be useful for debugging or analysis to see which
objects are stored as delta bases on top of others. This
information is available by running `git verify-pack`, but
that is extremely expensive (and is harder than necessary to
parse).
Instead, let's make it available as a cat-file query format,
which makes it fast and simple to get the bases for a subset
of the objects.

git log did not correctly handle decorations when a tag object referenced
another tag object that was no longer a ref, such as when the second tag was
deleted. The commit would not be decorated correctly because parse_object had
not been called on the second tag and therefore its tagged field had not been
filled in, resulting in none of the tags being associated with the relevant
commit.
Call parse_object to fill in this field if it is absent so that the chain of
tags can be dereferenced and the commit can be properly decorated. Include
tests as well to prevent future regressions.

The -O flag really shouldn't silently fail to do anything when given
a path that it can't read from.
However, it should be able to read from un-mmappable files, such as:
* pipes/fifos
* /dev/null: It's a character device (at least on Linux)
* ANY empty file:
Quoting Linux mmap(2), "SUSv3 specifies that mmap() should fail if
length is 0. However, in kernels before 2.6.12, mmap() succeeded in
this case: no mapping was created and the call returned addr. Since
kernel 2.6.12, mmap() fails with the error EINVAL for this case."
We especially want "-O/dev/null" to work, since we will be documenting
it as the way to cancel "diff.orderfile" when we add that.
(Note: "-O/dev/null" did have the right effect, since the existing error
handling essentially worked out to "silently ignore the orderfile". But
this was probably more coincidence than anything else.)
So, lets toss all of that logic to get the file mmapped and just use
strbuf_read_file() instead, which gives us decent error handling
practically for free.

The "--tags" option to "git fetch" used to be literally a synonym to
a "refs/tags/*:refs/tags/*" refspec, which meant that (1) as an
explicit refspec given from the command line, it silenced the lazy
"git fetch" default that is configured, and (2) also as an explicit
refspec given from the command line, it interacted with "--prune"
to remove any tag that the remote we are fetching from does not
have.
This demotes it to an option; with it, we fetch all tags in
addition to what would be fetched without the option, and it does
not interact with the decision "--prune" makes to see what
remote-tracking refs the local has are missing the remote
counterpart.

git diff --no-index ... currently reads the index, during setup, when
calling gitmodules_config(). This results in worse performance when the
index is not actually needed. This patch avoids calling
gitmodules_config() when the --no-index option is given. The times for
executing "git diff --no-index" in the WebKit repository are improved as
follows:
Test HEAD~3 HEAD
------------------------------------------------------------------
4001.1: diff --no-index 0.24(0.15+0.09) 0.01(0.00+0.00) -95.8%
An additional improvement of this patch is that "git diff --no-index" no
longer breaks when the index file is corrupt, which makes it possible to
use it for investigating the broken repository.
To improve the possible usage as investigation tool for broken
repositories, setup_git_directory_gently() is also not called when the
--no-index option is given.
Also add a test to guard against future breakages, and a performance
test to show the improvements.

When checking to see if some objects are of the same type
and when displaying the type of objects, git replace uses
the sha1_object_info() function.
Unfortunately this function by default respects replace
refs, so instead of the type of a replaced object, it
gives the type of the replacement object which might
be different.
To fix this bug, and because git replace should work at a
level before replacement takes place, let's unset the
read_replace_refs global variable at the beginning of
cmd_replace().
