We punt from repairing the cache-tree during a branch switching if
it involves having to create a new tree object that does not yet
exist in the object store. "mkdir dir && >dir/file && git add dir"
followed by "git checkout" is one example, when a tree that records
the state of such "dir/" is not in the object store.
However, after discovering that we do not have a tree object that
records the state of "dir/", the caller failed to remember the fact
that it noticed the cache-tree entry it received for "dir/" is
invalidated, it already knows it should not be populating the level
that has "dir/" as its immediate subdirectory, and it is not an
error at all for the sublevel cache-tree entry gave it a bogus
object name it shouldn't even look at.
This led the caller to detect and report a non-existent error. The
end result was the same and we avoided stuffing a non-existent tree
to the cache-tree, but we shouldn't have issued an alarming error
message to the user.

After we have packed all refs, we prune any loose refs that
correspond to what we packed. We do so by first taking a
lock with lock_ref_sha1, and then deleting the loose ref
file.
However, lock_ref_sha1 will refuse to take a lock on any
refs that exist at the top-level of the "refs/" directory,
and we skip pruning the ref. This is almost certainly not
what we want to happen here. The criteria to be pruned
should not differ from that to be packed; if a ref makes it
to prune_ref, it's because we want it both packed and
pruned (if there are refs you do not want to be packed, they
should be omitted much earlier by pack_ref_is_possible,
which we do in this case if --all is not given).
We can fix this by switching to lock_any_ref_for_update.
This behaves exactly the same with the exception of this
top-level check.

When we do a combined diff, we individually diff against
each parent, and then use intersect_paths to do a parallel
walk through the sorted results and come up with a final
list of interesting paths.
The sort order here is that returned by the diffs, which
means it is in git's tree-order which sorts sub-trees as if
their paths have "/" at the end. When we do our parallel
walk, we need to use a comparison function which provides
the same order.
Since 8518ff8 (combine-diff: optimize combine_diff_path sets
intersection, 2014-01-20), we use a simple strcmp to
compare the pathnames, and get this wrong. It's somewhat
hard to trigger because normally a diff does not produce
tree entries at all, and therefore the sort order is the
same as a strcmp. However, if the "-t" option is used with
the diff, then we will produce diff_filepairs for both trees
and files.
We can use base_name_compare to do the comparison, just as
the tree-diff code does. Even though what we have are not
technically base names (they are full paths within the
tree), the end result is the same (we do not care about
interior slashes at all, only about the final character).
However, since we do not have the length of each path
stored, we take a slight shortcut: if neither of the entries
is a sub-tree then the comparison is equivalent to a strcmp.
This lets us skip the extra strlen calls in the common case
without having to reimplement base_name_compare from
scratch.

Too large files may lead to failure to allocate memory. If it happens
here, it could impact quite a few commands that involve

most likely non-text), so mark them binary and skip looking at their

Fewer die() gives better control to the caller, provided that the

Reachability bitmaps do not work with shallow operations,
because they cache a view of the object reachability that
represents the true objects. Whereas a shallow repository
(or a shallow operation in a repository) is inherently
cutting off the object graph with a graft.
We explicitly disallow the use of bitmaps in shallow
repositories by checking is_repository_shallow(), and we
should continue to do that. However, we also want to
disallow bitmaps when we are serving a fetch to a shallow
client, since we momentarily take on their grafted view of
the world.
It used to be enough to call is_repository_shallow at the
start of pack-objects. Upload-pack wrote the other side's
shallow state to a temporary file and pointed the whole
pack-objects process at this state with "git --shallow-file",
and from the perspective of pack-objects, we really were
in a shallow repo. But since b790e0f (upload-pack: send
shallow info over stdin to pack-objects, 2014-03-11), we do
it differently: we send --shallow lines to pack-objects over
stdin, and it registers them itself.
This means that our is_repository_shallow check is way too
early (we have not been told about the shallowness yet), and
that it is insufficient (calling is_repository_shallow is
not enough, as the shallow grafts we register do not change
its return value). Instead, we can just turn off bitmaps
explicitly when we see these lines.

The main loop in strbuf_utf8_replace() could summed up as:
while ('src' is still valid) {
1) advance 'src' to copy ANSI escape sequences
2) advance 'src' to copy/replace visible characters
}
The problem is after #1, 'src' may have reached the end of the string
(so 'src' points to NUL) and #2 will continue to copy that NUL as if
it's a normal character. Because the output is stored in a strbuf,
this NUL accounted in the 'len' field as well. Check after #1 and
break the loop if necessary.
The test does not look obvious, but the combination of %>>() should
make a call trace like this
show_log()
pretty_print_commit()
format_commit_message()
strbuf_expand()
format_commit_item()
format_and_pad_commit()
strbuf_utf8_replace()
where %C(auto)%d would insert a color reset escape sequence in the end
of the string given to strbuf_utf8_replace() and show_log() uses
fwrite() to send everything to stdout (including the incorrect NUL
inserted by strbuf_utf8_replace)

When you list stashes, you can provide arbitrary git-log
options to change the display. However, adding just "-p"
does nothing, because each stash is actually a merge commit.
This implementation detail is easy to forget, leading to
confused users who think "-p" is not working. We can make
this easier by defaulting to "--first-parent -m", which will
show the diff against the working tree. This omits the
index portion of the stash entirely, but it's simple and it
matches what "git stash show" provides.
People who are more clueful about stash's true form can use
"--cc" to override the "-m", and the "--first-parent" will
then do nothing. For diffs, it only affects non-combined
diffs, so "--cc" overrides it. And for the traversal, we are
walking the linear reflog anyway, so we do not even care
about the parents.

Whitespace breakages are checked while the patch is being parsed.
Disable them at the beginning of parse_chunk(), where each
individual patch is parsed, immediately after we learn the name of
the file the patch applies to and before we start parsing the diff
contained in the patch.
One may naively think that we should be able to not just skip the
whitespace checks but simply fast-forward to the next patch without
doing anything once use_patch() tells us that this patch is not
going to be used. But in reality we cannot really skip much of the
parsing in order to do such a "fast-forward", primarily because
parsing "@@ -k,l +m,n @@" lines and counting the input lines is how
we determine the boundaries of individual patches.

We parse each patchfile and find the name of the path the patch
applies to, and then use that name to consult the attribute system
to find the whitespace rules to be used, and also the target file
(either in the working tree or in the index) to replay the changes
against.
Unlike a Git-generated patch, a non-Git patch is taken to have the
pathnames relative to the current working directory. The names
found in such a patch are modified by prepending the prefix by the
prefix_patches() helper function introduced in 56185f49 (git-apply:
require -p<n> when working in a subdirectory., 2007-02-19).
However, this prefixing is done after the patch is fully parsed and
affects only what target files are patched. Because the attributes
are checked against the names found in the patch during the parsing,
not against the final pathname, the whitespace check that is done
during parsing ends up using attributes for a wrong path for non-Git
patches.
Fix this by doing the prefix much earlier, immediately after the
header part of each patch is parsed and we learn the name of the
path the patch affects.

Of all the functions in `git_config*()` family, `git_config()` has the
most invocations in the whole code base. Each `git_config()` invocation
causes config file rereads which can be avoided using the config-set API.
Use the config-set API to rewrite `git_config()` to use the config caching
layer to avoid config file rereads on each invocation during a git process
lifetime. First invocation constructs the cache, and after that for each
successive invocation, `git_config()` feeds values from the config cache
instead of rereading the configuration files.
