There are buggy implementations of S_ISxxx(m) macros on some platforms
(e.g. NetBSD). The issue is that NetBSD doesn't take care to wrap its
macro arguments in parentheses, so on Linux and sane systems we have
S_ISREG(m) defined as something like:
(((m) & S_IFMT) == S_IFREG)
But on NetBSD:
((m & _S_IFMT) == _S_IFREG)
Since a caller in builtin/diff.c called our macro as `S_IFREG | 0644'
this bug introduced a logic error on NetBSD, since the precedence of
bit-wise & is higher than | in C.

The ctype functions isspace(), isalnum(), et al take an integer
argument representing an unsigned character, or -1 for EOF. On
platforms with a signed char, it is unsafe to pass a char to them
without casting it to unsigned char first.
Most of git is already shielded against this by the ctype
implementation in git-compat-util.h, but xdiff, which uses libc
ctype.h, ought to be fixed.

The buffer used to construct paths like ".git/objects/info" and
".git/objects/pack" is allocated on the heap and never freed.
So free it. While at it, factor out the relevant code into its own
function and rename the sha1_dir variable to object_directory (to
match the change in everyday usage after the renaming of
SHA1_FILE_DIRECTORY in v0.99~603^2~7, 2005).
Noticed by valgrind while setting up tests (in test-lib).

If setup_git_env() is run before the usual repository discovery
sequence and .git is a file with the text
gitdir: <path>
(with <path> any string) then the in-core git_dir variable is set to
the result of converting <path> to an absolute path using
make_absolute_path().
Unfortunately make_absolute_path() returns its result in a static
buffer that is overwritten by later calls. Such a call could cause
later accesses to git_dir (from git_pathdup(), for example) to read
the wrong path, leaving git very confused.
It is not obvious whether any existing code in git will trigger the
problem, but in any case, it is worth a few dozen bytes to copy the
return value from make_absolute_path() for some added peace of mind.

For each hunk, xdl_find_func searches the preimage for a function name
until the beginning of the file. If the file does not contain any
function names, this search has complexity O(n^2) in the number of
hunks n.
Instead, inline xdl_find_func() and keep track of up to which line we
have scanned already and the contents of the last funcname line that
we have found.

git blame --textconv is wrongly calling the textconv filter on
symlinks: symlinks are stored as blobs whose content is the target of
the link, and blame calls the textconv filter on a temporary file
filled-in with the content of this blob.
For example:
$ git blame -C -C regular-file.pdf
Error: May not be a PDF file (continuing anyway)
Error: PDF file is damaged - attempting to reconstruct xref table...
Error: Couldn't find trailer dictionary
Error: Couldn't read xref table
Warning: program returned non-zero exit code #1
fatal: unable to read files to diff
That errors come from pdftotext run on symlink.pdf being extracted to
/tmp/ with one-line plain-text content pointing to link destination.
So several failures are demonstrated here:
- git cat-file --textconv :symlink.bin # also HEAD:symlink.bin
- git blame --textconv symlink.bin
- git blame -C -C --textconv regular-file # but also looks on symlink.bin
At present they all fail with something like.
E: /tmp/j3ELEs_symlink.bin is not "binary" file
NOTE: git diff doesn't try to textconv the pathnames, it runs the
textual diff without textconv, which is the expected behavior.

The textconv filter is sometimes incorrectly ran on a temporary file
whose content is the target of a symbolic link, instead of actual file
content. Prepare to test this by marking the content of the file to
convert with "bin:", and let the helper die if "bin:" is not found in
the file content.
NOTE: I've changed $@ to $1 in helper becase textconv program "should
take a single argument" (see Documentation/gitattributes.txt), so
making this more explicit makes sense and also helps to avoid
problems with feeding arguments to echo.

In 479b56ba ('make "repack -f" imply "pack-objects --no-reuse-object"'),
git repack -f was changed to include recompressing all objects on the
zlib level on the assumption that if the user wants to spend that much
time already, some more time won't hurt (and recompressing is useful if
the user changed the zlib compression level).
However, "some more time" can be quite long with very big repositories,
so some users are going to appreciate being able to choose. If we are
going to give them the choice, --no-reuse-object will probably be
interesting a lot less frequently than --no-reuse-delta. Hence, this
reverts -f to the old behaviour (--no-reuse-delta) and adds a new -F
option that replaces the current -f.
Measurements taken using this patch on a current clone of git.git
indicate a 17% decrease in time being made available to users:
git repack -Adf 34.84s user 0.56s system 145% cpu 24.388 total

cherry-pick will segfault when transplanting a root commit if the --ff
option is used. This happens because the "parent" pointer is set to NULL
when the commit being cherry-picked has no parents. Later, when "parent"
is dereferenced, the cherry-pick segfaults.
Fix this by checking whether "parent" is NULL before dereferencing it and
add a test for this case of cherry-picking a root commit with --ff.
