After finding a function line for --function-context in the pre-image,
xdl_emit_diff() calculates the equivalent line in the post-image. It
assumes that the lines between changes are the same on both sides. If
the option --ignore-blank-lines was also given then this is not
necessarily true.
Clamp the calculation results for start and end of the function context
to prevent out-of-bounds array accesses.
Note that this _just_ fixes the case where our mismatch sends us off the
beginning of the file. There are likely other cases where our assumption
causes us to go to the wrong line within the file. Nobody has developed
a test case yet, and the ultimate fix is likely more complicated than
this patch. But this at least prevents a segfault in the meantime.

When `lstat()` failed, `git clean` would abort without an error
message, leaving the user quite puzzled.
In particular on Windows, where the default maximum path length is
quite small (yet there are ways to circumvent that limit in many
cases), it is very important that users be given an indication why
their command failed because of too long paths when it did.
This test case makes sure that a warning is issued that would have
helped the user who reported this issue:
https://github.com/git-for-windows/git/issues/521
Note that we temporarily set `core.longpaths = false` in the regression
test; this ensures forward-compatibility with the `core.longpaths`
feature that has not yet been upstreamed from Git for Windows.

When resolving a conflict on a path in favor of removing it, using
"git rm" on it is the standard way to do so. The user however is
greeted with a "needs merge" message during that operation:
$ git merge side-branch
$ edit conflicted-path-1
$ git add conflicted-path-1
$ git rm conflicted-path-2
conflicted-path-2: needs merge
rm 'conflicted-path-2'
The removal by "git rm" does get performed, but an uninitiated user
may find it confusing, "needs merge? so I need to resolve conflict
before being able to remove it???"
The message is coming from "update-index --refresh" that is called
internally to make sure "git rm" knows which paths are clean and
which paths are dirty, in order to prevent removal of paths modified
relative to the index without the "-f" option. We somehow ended up
not squelching this message which seeped through to the UI surface.
Use the same mechanism used by "git commit", "git describe", etc. to
squelch the message.

git stash push --keep-index is supposed to keep all changes that have
been added to the index, both in the index and on disk.
Currently this doesn't behave correctly when a file is removed from
the index. Instead of keeping it deleted on disk, --keep-index
currently restores the file.
Fix that behaviour by using 'git checkout' in no-overlay mode which
can faithfully restore the index and working tree. This also
simplifies the code.
Note that this will overwrite untracked files if the untracked file
has the same name as a file that has been deleted in the index.

On some older Windows versions (e.g. Windows 7), the CreateProcessW()
function does not really support spaces in its first argument,
lpApplicationName. But it supports passing NULL as lpApplicationName,
which makes it figure out the application from the (possibly quoted)
first argument of lpCommandLine.
Let's use that trick (if we are certain that the first argument matches
the executable's path) to support launching programs whose path contains
spaces.

Teach transport-helper how to notice if skipping a ref during push would
violate atomicity on the client side. We notice that a ref would be
rejected, and choose not to send it, but don't notice that if the client
has asked for --atomic we are violating atomicity if all the other
pushes we are sending would succeed. Asking the server end to uphold
atomicity wouldn't work here as the server doesn't have any idea that we
tried to update a ref that's broken.
The added test-case is a succinct way to reproduce this issue that fails
today. The same steps work fine when we aren't using a transport-helper

In a range-diff it's not always clear which file a certain funcname of

Add the filename to the inner diffs header, so it's always visible to

Currently range-diff keeps the diff header of the inner diff
intact (apart from stripping lines starting with index). This diff
header is somewhat useful, especially when files get different
names in different ranges.
However there is no real need to keep the whole diff header for that.
The main reason we currently do that is probably because it is easy to
do.
Introduce a new range diff hunk header, that's enclosed by "##",
similar to how line numbers in diff hunks are enclosed by "@@", and
give human readable information of what exactly happened to the file,
including the file name.
This improves the readability of the range-diff by giving more concise
information to the users. For example if a file was renamed in one
iteration, but not in another, the diff of the headers would be quite
noisy. However the diff of a single line is concise and should be
easier to understand.
Additionally, this allows us to add these range diff section headers to
the outer diffs hunk headers using a custom userdiff pattern, which
should help making the range-diff more readable.

The line count in the outer diff's hunk headers of a range diff is not
all that interesting. It merely shows how far along the inner diff
are on both sides. That number is of no use for human readers, and
range-diffs are not meant to be machine readable.
In a subsequent commit we're going to add some more contextual
information such as the filename corresponding to the diff to the hunk
headers. Remove the unnecessary information, and just keep the "@@"
to indicate that a new hunk of the outer diff is starting.

When postprocessing the inner diff in range-diff, we currently replace
the whole hunk header line with just "@@". This matches how 'git
tbdiff' used to handle hunk headers as well.
Most likely this is being done because line numbers in the hunk header
are not relevant without other changes. They can for example easily
change if a range is rebased, and lines are added/removed before a
change that we actually care about in our ranges.
However it can still be useful to have the function name that 'git
diff' extracts as additional context for the change.
Note that it is not guaranteed that the hunk header actually shows up
in the range-diff, and this change only aims to improve the case where
a hunk header would already be included in the final output.

Make the copy_or_link_directory function no longer skip hidden

The reason for that could be unintentional: probably the intention was

dir_iterator_advance() is a large function with two nested loops. Let's
improve its readability factoring out three functions and simplifying
its mechanics. The refactored model will no longer depend on
level.initialized and level.dir_state to keep track of the iteration
state and will perform on a single loop.
Also, dir_iterator_begin() currently does not check if the given string
represents a valid directory path. Since the refactored model will have
to stat() the given path at initialization, let's also check for this
kind of error and make dir_iterator_begin() return NULL, on failures,
with errno appropriately set. And add tests for this new behavior.
Improve documentation at dir-iteration.h and code comments at
dir-iterator.c to reflect the changes and eliminate possible
ambiguities.
Finally, adjust refs/files-backend.c to check for now possible
dir_iterator_begin() failures.

There is currently an odd behaviour when locally cloning a repository
with symlinks at .git/objects: using --no-hardlinks all symlinks are
dereferenced but without it, Git will try to hardlink the files with the
link() function, which has an OS-specific behaviour on symlinks. On OSX
and NetBSD, it creates a hardlink to the file pointed by the symlink
whilst on GNU/Linux, it creates a hardlink to the symlink itself.
On Manjaro GNU/Linux:
$ touch a
$ ln -s a b
$ link b c
$ ls -li a b c
155 [...] a
156 [...] b -> a
156 [...] c -> a
But on NetBSD:
$ ls -li a b c
2609160 [...] a
2609164 [...] b -> a
2609160 [...] c
It's not good to have the result of a local clone to be OS-dependent and
besides that, the current behaviour on GNU/Linux may result in broken
symlinks. So let's standardize this by making the hardlinks always point
to dereferenced paths, instead of the symlinks themselves. Also, add
tests for symlinked files at .git/objects/.
Note: Git won't create symlinks at .git/objects itself, but it's better
to handle this case and be friendly with users who manually create them.

Add tests for what happens when we perform a local clone on a repo
containing odd files at .git/object directory, such as symlinks to other
dirs, or unknown files.
I'm bending over backwards here to avoid a SHA-1 dependency. See [1]
for an earlier and simpler version that hardcoded SHA-1s.
This behavior has been the same for a *long* time, but hasn't been
tested for.
There's a good post-hoc argument to be made for copying over unknown
things, e.g. I'd like a git version that doesn't know about the
commit-graph to copy it under "clone --local" so a newer git version
can make use of it.
In follow-up commits we'll look at changing some of this behavior, but
for now, let's just assert it as-is so we'll notice what we'll change
later.
