It can be useful to split your ~/.gitconfig across multiple
files. For example, you might have a "main" file which is
used on many machines, but a small set of per-machine
tweaks. Or you may want to make some of your config public
(e.g., clever aliases) while keeping other data back (e.g.,
your name or other identifying information). Or you may want
to include a number of config options in some subset of your
repos without copying and pasting (e.g., you want to
reference them from the .git/config of participating repos).
This patch introduces an include directive for config files.
It looks like:
[include]
path = /path/to/file
This is syntactically backwards-compatible with existing git
config parsers (i.e., they will see it as another config
entry and ignore it unless you are looking up include.path).
The implementation provides a "git_config_include" callback
which wraps regular config callbacks. Callers can pass it to
git_config_from_file, and it will transparently follow any
include directives, passing all of the discovered options to
the real callback.
Include directives are turned on automatically for "regular"
git config parsing. This includes calls to git_config, as
well as calls to the "git config" program that do not
specify a single file (e.g., using "-f", "--global", etc).
They are not turned on in other cases, including:
1. Parsing of other config-like files, like .gitmodules.
There isn't a real need, and I'd rather be conservative
and avoid unnecessary incompatibility or confusion.
2. Reading single files via "git config". This is for two
reasons:
a. backwards compatibility with scripts looking at
config-like files.
b. inspection of a specific file probably means you
care about just what's in that file, not a general
lookup for "do we have this value anywhere at
all". If that is not the case, the caller can
always specify "--includes".
3. Writing files via "git config"; we want to treat
include.* variables as literal items to be copied (or
modified), and not expand them. So "git config
--unset-all foo.bar" would operate _only_ on
.git/config, not any of its included files (just as it
also does not operate on ~/.gitconfig).

The git-config command sometimes operates on the default set
of config files (either reading from all, or writing to repo
config), and sometimes operates on a specific file. In the
latter case, we set the magic global config_exclusive_filename,
and the code in config.c does the right thing.
Instead, let's have git-config use the "advanced" variants
of config.c's functions which let it specify an individual
filename (or NULL for the default). This makes the code a
lot more obvious, and fixes two small bugs:
1. A relative path specified by GIT_CONFIG=foo will look
in the wrong directory if we have to chdir as part of
repository setup. We already handle this properly for
"git config -f foo", but the GIT_CONFIG lookup used
config_exclusive_filename directly. By dropping to a
single magic variable, the GIT_CONFIG case now just
works.
2. Calling "git config -f foo --edit" would not respect
core.editor. This is because just before editing, we
called git_config, which would respect the
config_exclusive_filename setting, even though this
particular git_config call was not about looking in the
user's specified file, but rather about loading actual
git config, just as any other git program would.

The prefix_filename function returns a pointer to a static
buffer which may be overwritten by subsequent calls. Since
we are going to keep the result around for a while, let's be
sure to duplicate it for safety.
I don't think this can be triggered as a bug in the current
code, but it's a good idea to be defensive, as any resulting
bug would be quite subtle.

Receive runs rev-list --verify-objects in order to detect missing
objects. However, such errors are ignored and overridden later.
Instead, consequently ignore all update commands for which an error has
already been detected.
Some tests in t5504 are obsoleted by this change, because invalid
objects are detected even if fsck is not enabled. Instead, they now test
for different error messages depending on whether or not fsck is turned
on. A better fix would be to force a corruption that will be detected by
fsck but not by rev-list.

"git tag -n" did not check the type of the object it is reading the top n
lines from. At least, avoid showing the beginning of trees and blobs when
dealing with lightweight tags that point at them.
As the payload of a tag and a commit look similar in that they both start
with a header block, which is skipped for the purpose of "-n" output,
followed by human readable text, allow the message of commit objects to be
shown just like the contents of tag objects. This avoids regression for
people who have been using "tag -n" to show the log messages of commits
that are pointed at by lightweight tags.

When the userdiff_config function was introduced in be58e70
(diff: unify external diff and funcname parsing code,
2008-10-05), it used a return value convention unlike any
other config callback. Like other callbacks, it used "-1" to
signal error. But it returned "1" to indicate that it found
something, and "0" otherwise; other callbacks simply
returned "0" to indicate that no error occurred.
This distinction was necessary at the time, because the
userdiff namespace overlapped slightly with the color
configuration namespace. So "diff.color.foo" could mean "the
'foo' slot of diff coloring" or "the 'foo' component of the
"color" userdiff driver". Because the color-parsing code
would die on an unknown color slot, we needed the userdiff
code to indicate that it had matched the variable, letting
us bypass the color-parsing code entirely.
Later, in 8b8e862 (ignore unknown color configuration,
2009-12-12), the color-parsing code learned to silently
ignore unknown slots. This means we no longer need to
protect userdiff-matched variables from reaching the
color-parsing code.
We can therefore change the userdiff_config calling
convention to a more normal one. This drops some code from
each caller, which is nice. But more importantly, it reduces
the cognitive load for readers who may wonder why
userdiff_config is unlike every other config callback.
There's no need to add a new test confirming that this
works; t4020 already contains a test that sets
diff.color.external.

When the HEAD of the submodule matches what is recorded in the index of

offered by "git add -e" for editing shows a diff like this:
diff --git a/submodule b/submodule
<header>
-deadbeef...
+deadbeef...-dirty
Because applying such a patch has no effect to the index, this is a
useless noise. Generate the patch with IGNORE_DIRTY_SUBMODULES flag to
prevent such a change from getting reported.
This patch also loses the "-dirty" suffix from the output when the HEAD of
the submodule is different from what is in the index of the superproject.
As such dirtiness expressed by the suffix does not affect the result of
the patch application at all, there is no information lost if we remove
it. The user could still run "git status" before "git add -e" if s/he
cares about the dirtiness.

We don't usually bother looking at tagged objects at all
when listing. However, if "-n" is specified, we open the
objects to read the annotations of the tags. If we fail to
read an object, or if the object has zero length, we simply
silently return.
The first case is an indication of a broken or corrupt repo,
and we should notify the user of the error.
The second case is OK to silently ignore; however, the
existing code leaked the buffer returned by read_sha1_file.

When "git tag" is instructed to print lines from annotated
tags via "-n", it first prints the tag name, then attempts
to parse and print the lines of the tag object, and then
finally adds a trailing newline.
If an error occurs, we return early from the function and
never print the newline, screwing up the output for the next
tag. Let's factor the line-printing into its own function so
we can manage the early returns better, and make sure that
we always terminate the line.

fix push --quiet: add 'quiet' capability to receive-pack
server_supports(): parse feature list more carefully
It is very easy to mistype the branch name when editing its description,
e.g.
$ git checkout -b my-topic master
: work work work
: now we are at a good point to switch working something else
$ git checkout master
: ah, let's write it down before we forget what we were doing
$ git branch --edit-description my-tpoic
The command does not notice that branch 'my-tpoic' does not exist. It is
not lost (it becomes description of an unborn my-tpoic branch), but is not
very useful. So detect such a case and error out to reduce the grief
factor from this common mistake.
This incidentally also errors out --edit-description when the HEAD points
at an unborn branch (immediately after "init", or "checkout --orphan"),
because at that point, you do not even have any commit that is part of
your history and there is no point in describing how this particular
branch is different from the branch it forked off of, which is the useful
bit of information the branch description is designed to capture.
We may want to special case the unborn case later, but that is outside the
scope of this patch to prevent more common mistakes before 1.7.9 series
gains too much widespread use.

Starting at release v1.7.9, if you ask to merge a signed tag, "git merge"
always creates a merge commit, even when the tag points at a commit that
happens to be a descendant of your current commit.
Unfortunately, this interacts rather badly for people who use --ff-only to
make sure that their branch is free of local developments. It used to be
possible to say:
$ git checkout -b frotz v1.7.9~30
$ git merge --ff-only v1.7.9
and expect that the resulting tip of frotz branch matches v1.7.9^0 (aka
the commit tagged as v1.7.9), but this fails with the updated Git with:
fatal: Not possible to fast-forward, aborting.
because a merge that merges v1.7.9 tag to v1.7.9~30 cannot be created by
fast forwarding.
We could teach users that now they have to do
$ git merge --ff-only v1.7.9^0
but it is far more pleasant for users if we DWIMmed this ourselves.
When an integrator pulls in a topic from a lieutenant via a signed tag,
even when the work done by the lieutenant happens to fast-forward, the
integrator wants to have a merge record, so the integrator will not be
asking for --ff-only when running "git pull" in such a case. Therefore,
this change should not regress the support for the use case v1.7.9 wanted
to add.
