"new safer autocrlf handling":
- Check if eols in a file are converted at commit, when the file has
CR (or CRLF) in the repo (technically speaking in the index).
- Add a test-file repoMIX with mixed line-endings.
- When converting LF->CRLF or CRLF->LF: check the warnings
checkout_files():
- Checking out CRLF_nul and checking for eol coversion does not
make much sense (CRLF will stay CRLF).
- Use the file LF_nul instead: It is handled a binary in "auto" modes,
and when declared as text the LF may be replaced with CRLF, depending
on the configuration.

Perforce allows client side file/directory remapping through
the use of the client view definition that is part of the
user's client spec.
To support this functionality while branch detection is
enabled it is important to determine the branch location in
the workspace such that the correct files are patched before
Perforce submission. Perforce provides a command that
facilitates this process: p4 where.
This patch does two things to fix improve file location
detection when git-p4 has branch detection and use of client
spec enabled:
1. Enable usage of "p4 where" when Perforce branches exist
in the git repository, even when client specification is
used. This makes use of the already existing function
p4Where.
2. Allow identifying partial matches of the branch's depot
path while processing the output of "p4 where". For
robustness, paths will only match if ending in "/...".

$GIT_DIR/info/exclude and core.excludesfile (which falls back to

lists given by the project in .gitignore files. The former, which
is per-repository personal preference, should take precedence over
the latter, which is a personal preference default across different

However, the precedence order was screwed up between these two from

When the "git" wrapper is invoked, we prepend the baked-in
exec-path to our PATH, so that any sub-processes we exec
will all find the git-foo commands that match the wrapper
version.
If you invoke git with an absolute path, like:
/usr/bin/git foo
we also prepend "/usr/bin" to the PATH. This was added long
ago by by 231af83 (Teach the "git" command to handle some
commands internally, 2006-02-26), with the intent that
things would just work if you did something like:
cd /opt
tar xzf premade-git-package.tar.gz
alias git=/opt/git/bin/git
as we would then find all of the related external commands
in /opt/git/bin. I.e., it made git runtime-relocatable,
since at the time of 231af83, we installed all of the git
commands into $(bindir). But these days, that is not enough.
Since f28ac70 (Move all dashed-form commands to libexecdir,
2007-11-28), we do not put commands into $(bindir), and you
actually need to convert "/usr/bin" into "/usr/libexec". And
not just for finding binaries; we want to find $(sharedir),
etc, the same way. The RUNTIME_PREFIX build knob does this
the right way, by assuming a sane hierarchy rooted at
"$prefix" when we run "$prefix/bin/git", and inferring
"$prefix/libexec/git-core", etc.
So this feature (prepending the argv[0] dirname to the PATH)
is broken for providing a runtime prefix, and has been for
many years. Does it do anything for other cases?
For the "git" wrapper itself, as well as any commands
shipped by "git", the answer is no. Those are already in
git's exec-path, which is consulted first. For third-party
commands which you've dropped into the same directory, it
does include them. So if you do
cd /opt
tar xzf git-built-specifically-for-opt-git.tar.gz
cp third-party/git-foo /opt/git/bin/git-foo
alias git=/opt/git/bin/git
it does mean that we will find the third-party "git-foo",
even if you do not put /opt/git/bin into your $PATH. But
the flipside of this is that we will bump the precedence of
_other_ third-party tools that happen to be in the same
directory as git. For example, consider this setup:
1. Git is installed by the system in /usr/bin. There are
other system utilities in /usr/bin. E.g., a system
"vi".
2. The user installs tools they prefer in /usr/local/bin.
E.g., vim with a "vi" symlink. They set their PATH to
/usr/local/bin:/usr/bin to prefer their custom tools.
3. Running /usr/bin/git puts "/usr/bin" at the front of
their PATH. When git invokes the editor on behalf of
the user, they get the system vi, not their normal vim.
There are other variants of this, including overriding
system ruby and python (which is quite common using tools
like "rvm" and "virtualenv", which use relocatable
hierarchies and $PATH settings to get a consistent
environment).
Given that the main motivation for git placing the argv[0]
dirname into the PATH has been broken for years, that the
remaining cases are obscure and unlikely (and easily fixed
by the user just setting up their $PATH sanely), and that
the behavior is hurting real, reasonably common use cases,
it's not worth continuing to do so.

If you have staged contents in your index and run "stash
apply", we may hit a conflict and put new entries into the
index. Recovering to your original state is difficult at
that point, because tools like "git reset --keep" will blow
away anything staged. We can make this safer by refusing to
apply when there are staged changes.
It's possible we could provide better tooling here, as "git
stash apply" should be writing only conflicts to the index
(so we know that any stage-0 entries are potentially
precious). But it is the odd duck; most "mergy" commands
will update the index for cleanly merged entries, and it is
not worth updating our tooling to support this use case
which is unlikely to be of interest (besides which, we would
still need to block a dirty index for "stash apply --index",
since that case _would_ be ambiguous).

One of the tests in t3903 wants to make sure that applying a
stash that touches only "file" can still happen even if there
are working tree changes to "other-file". To do so, it adds
"other-file" to the index (since otherwise it is an
untracked file, voiding the purpose of the test).
But as we are about to refactor the dirty-index handling,
and as this test does not actually care about having a dirty
index (only a dirty working tree), let's bump the tracking
of "other-file" into the setup phase, so we can have _just_

Since 33d4221 (write_sha1_file: freshen existing objects,
2014-10-15), we update the mtime of existing objects that we
would have written out (had they not existed). For the
common case in which many objects are packed, we may update
the mtime on a single packfile repeatedly. This can result
in a noticeable performance problem if calling utime() is
expensive (e.g., because your storage is on NFS).
We can fix this by keeping a per-pack flag that lets us
freshen only once per program invocation.
An alternative would be to keep the packed_git.mtime flag up
to date as we freshen, and freshen only once every N
seconds. In practice, it's not worth the complexity. We are
racing against prune expiration times here, which inherently
must be set to accomodate reasonable program running times
(because they really care about the time between an object
being written and it becoming referenced, and the latter is
typically the last step a program takes).

When writing out an object file, we first check whether it
already exists and if so optimize out the write. Prior to
33d4221, we did this by calling has_sha1_file(), which will
check for packed objects followed by loose. Since that
commit, we check loose objects first.
For the common case of a repository whose objects are mostly
packed, this means we will make a lot of extra access()
system calls checking for loose objects. We should follow
the same packed-then-loose order that all of our other
lookups use.

When pruning and repacking a repository that has an
alternate object store configured, we may traverse a large
number of objects in the alternate. This serves no purpose,
and may be expensive to do. A longer explanation is below.
Commits d3038d2 and abcb865 taught prune and pack-objects
(respectively) to treat "recent" objects as tips for
reachability, so that we keep whole chunks of history. They
built on the object traversal in 660c889 (sha1_file: add
for_each iterators for loose and packed objects,
2014-10-15), which covers both local and alternate objects.
In both cases, covering alternate objects is unnecessary, as
both commands can only drop objects from the local
repository. In the case of prune, we traverse only the local
object directory. And in the case of repacking, while we may
or may not include local objects in our pack, we will never
reach into the alternate with "repack -d". The "-l" option
is only a question of whether we are migrating objects from
the alternate into our repository, or leaving them
untouched.
It is possible that we may drop an object that is depended
upon by another object in the alternate. For example,
imagine two repositories, A and B, with A pointing to B as
an alternate. Now imagine a commit that is in B which
references a tree that is only in A. Traversing from recent
objects in B might prevent A from dropping that tree. But
this case isn't worth covering. Repo B should take
responsibility for its own objects. It would never have had
the commit in the first place if it did not also have the
tree, and assuming it is using the same "keep recent chunks
of history" scheme, then it would itself keep the tree, as
well.
So checking the alternate objects is not worth doing, and
come with a significant performance impact. In both cases,
we skip any recent objects that have already been marked
SEEN (i.e., that we know are already reachable for prune, or
included in the pack for a repack). So there is a slight
waste of time in opening the alternate packs at all, only to
notice that we have already considered each object. But much
worse, the alternate repository may have a large number of
objects that are not reachable from the local repository at
all, and we end up adding them to the traversal.
We can fix this by considering only local unseen objects.

Once we know the number of objects in the input pack, we allocate an
array of nr_objects of struct delta_entry. On x86-64, this struct is
32 bytes long. The union delta_base, which is part of struct
delta_entry, provides enough space to store either ofs-delta (8 bytes)
or ref-delta (20 bytes).
Because ofs-delta encoding is more efficient space-wise and more
performant at runtime than ref-delta encoding, Git packers try to use
ofs-delta whenever possible, and it is expected that objects encoded
as ref-delta are minority.
In the best clone case where no ref-delta object is present, we waste
(20-8) * nr_objects bytes because of this union. That's about 38MB out
of 100MB for deltas[] with 3.4M objects, or 38%. deltas[] would be
around 62MB without the waste.
This patch attempts to eliminate that. deltas[] array is split into
two: one for ofs-delta and one for ref-delta. Many functions are also
duplicated because of this split. With this patch, ofs_deltas[] array
takes 51MB. ref_deltas[] should remain unallocated in clone case (0
bytes). This array grows as we see ref-delta. We save about half in
this case, or 25% of total bookkeeping.
The saving is more than the calculation above because some padding in
the old delta_entry struct is removed. ofs_delta_entry is 16 bytes,
including the 4 bytes padding. That's 13MB for padding, but packing
the struct could break platforms that do not support unaligned
access. If someone on 32-bit is really low on memory and only deals
with packs smaller than 2G, using 32-bit off_t would eliminate the
padding and save 27MB on top.
A note about ofs_deltas allocation. We could use ref_deltas memory
allocation strategy for ofs_deltas. But that probably just adds more
overhead on top. ofs-deltas are generally the majority (1/2 to 2/3) in
any pack. Incremental realloc may lead to too many memcpy. And if we
preallocate, say 1/2 or 2/3 of nr_objects initially, the growth rate
of ALLOC_GROW() could make this array larger than nr_objects, wasting
more memory.
