For exclude patterns read in from files, the filename is stored in the
exclude list, and the originating line number is stored in the
individual exclude (counting starting at 1).
For exclude patterns provided on the command line, a string describing
the source of the patterns is stored in the exclude list, and the
sequence number assigned to each exclude pattern is negative, with
counting starting at -1. So for example the 2nd pattern provided via
--exclude would be numbered -2. This allows any future consumers of
that data to easily distinguish between exclude patterns from files
vs. from the CLI.

Previously each exclude_list could potentially contain patterns
from multiple sources. For example dir->exclude_list[EXC_FILE]
would typically contain patterns from .git/info/exclude and
core.excludesfile, and dir->exclude_list[EXC_DIRS] could contain
patterns from multiple per-directory .gitignore files during
directory traversal (i.e. when dir->exclude_stack was more than
one item deep).
We split these composite exclude_lists up into three groups of
exclude_lists (EXC_CMDL / EXC_DIRS / EXC_FILE as before), so that each
exclude_list now contains patterns from a single source. This will
allow us to cleanly track the origin of each pattern simply by adding
a src field to struct exclude_list, rather than to struct exclude,
which would make memory management of the source string tricky in the
EXC_DIRS case where its contents are dynamically generated.
Similarly, by moving the filebuf member from struct exclude_stack to
struct exclude_list, it allows us to track and subsequently free
memory buffers allocated during the parsing of all exclude files,
rather than only tracking buffers allocated for files in the EXC_DIRS
group.

The documentation for the ALLOC_GROW API implicitly encouraged

We record the uncompressed and compressed sizes and the CRC of streamed
files as zero in the local header of the file. The actual values are
recorded in an extra data descriptor after the file content, and in the
usual ZIP directory entry at the end of the archive.
While we know the compressed size and the CRC only after we processed
the contents, we actually know the uncompressed size right from the
start. And for files that we store uncompressed we also already know
their final size.
Do it like InfoZIP's zip and recored the known values, even though they
can be reconstructed using the ZIP directory and the data descriptors
alone. InfoZIP's unzip worked fine before, but NetBSD's version
actually depends on these fields.
The uncompressed size is already set by sha1_object_info(). We just
need to initialize the compressed size to zero or the uncompressed size
depending on the compression method (0 means storing). The CRC was
propertly initialized already.

When a sub-command dies due to a signal, we encode the
signal number into the numeric exit status as "signal -
128". This is easy to identify (versus a regular positive
error code), and when cast to an unsigned integer (e.g., by
feeding it to exit), matches what a POSIX shell would return
when reporting a signal death in $? or through its own exit
code.
So we have a negative value inside the code, but once it
passes across an exit() barrier, it looks positive (and any
code we receive from a sub-shell will have the positive
form). E.g., death by SIGPIPE (signal 13) will look like
-115 to us in inside git, but will end up as 141 when we
call exit() with it. And a program killed by SIGPIPE but run
via the shell will come to us with an exit code of 141.
Unfortunately, this means that when the "use_shell" option
is set, we need to be on the lookout for _both_ forms. We
might or might not have actually invoked the shell (because
we optimize out some useless shell calls). If we didn't invoke
the shell, we will will see the sub-process's signal death
directly, and run-command converts it into a negative value.
But if we did invoke the shell, we will see the shell's
128+signal exit status. To be thorough, we would need to
check both, or cast the value to an unsigned char (after
checking that it is not -1, which is a magic error value).
Fortunately, most callsites do not care at all whether the
exit was from a code or from a signal; they merely check for
a non-zero status, and sometimes propagate the error via
exit(). But for the callers that do care, we can make life
slightly easier by just using the consistent positive form.
This actually fixes two minor bugs:
1. In launch_editor, we check whether the editor died from
SIGINT or SIGQUIT. But we checked only the negative
form, meaning that we would fail to notice a signal
death exit code which was propagated through the shell.
2. In handle_alias, we assume that a negative return value
from run_command means that errno tells us something
interesting (like a fork failure, or ENOENT).
Otherwise, we simply propagate the exit code. Negative
signal death codes confuse us, and we print a useless
"unable to run alias 'foo': Success" message. By
encoding signal deaths using the positive form, the
existing code just propagates it as it would a normal
non-zero exit code.
The downside is that callers of run_command can no longer
differentiate between a signal received directly by the
sub-process, and one propagated. However, no caller
currently cares, and since we already optimize out some
calls to the shell under the hood, that distinction is not
something that should be relied upon by callers.
Fix the same logic in t/test-terminal.perl for consistency [jc:
raised by Jonathan in the discussion].

The name field of a tar header has a size of 100 characters. This limit
was extended long ago in a backward compatible way by providing the
additional prefix field, which can hold 155 additional characters. The
actual path is constructed at extraction time by concatenating the prefix
field, a slash and the name field.
get_path_prefix() is used to determine which slash in the path is used as
the cutting point and thus which part of it is placed into the field
prefix and which into the field name. It tries to cram as much into the
prefix field as possible. (And only if we can't fit a path into the
provided 255 characters we use a pax extended header to store it.)
If a path is longer than 100 but shorter than 156 characters and ends
with a slash (i.e. is for a directory) then get_path_prefix() puts the
whole path in the prefix field and leaves the name field empty. GNU tar
reconstructs the path without complaint, but the tar included with
NetBSD 6 does not: It reports the header to be invalid.
For compatibility with this version of tar, make sure to never leave the
name field empty. In order to do that, trim the trailing slash from the
part considered as possible prefix, if it exists -- that way the last
path component (or more, but not less) will end up in the name field.

Since b57fb80a7d (init, clone: support --separate-git-dir for .git file)
git clone supports the --separate-git-dir option to create the git dir
outside the work tree. But when that option is used, the git dir won't be
deleted in case the clone fails like it would be without this option. This
makes clone lose its atomicity as in case of a failure a partly set up git
dir is left behind. A real world example where this leads to problems is
when "git submodule update" fails to clone a submodule and later calls to
"git submodule update" stumble over the partially set up git dir and try
to revive the submodule from there, which then fails with a not very user
friendly error message.
Fix that by updating the junk_git_dir variable (used to remember if and
what git dir should be removed in case of failure) to the new value given
with the --seperate-git-dir option. Also add a test for this to t5600 (and
while at it fix the former last test to not cd into a directory to test
for its existence but use "test -d" instead).

Our Makefile first sets up some sane per-platform defaults
by looking at "uname", then modifies that according to the
results of autoconf (if any), then modifies that according
to the user's wishes in config.mak.
For sub-Makefiles like Documentation/Makefile, the latter
two are available, but the uname defaults are available only
to the main Makefile. This hasn't been a problem so far,
because the sub-Makefiles do not rely on any of those
automatic settings to do their work.
This patch puts the uname magic into its own file so it can
be reused in other Makefiles, opening up the possibility of
new knobs.
Note that we leave one reference to uname in the top-level
Makefile: if we are on Darwin, we must check the NO_FINK and
NO_DARWIN_PORTS settings. But because we are combining uname
settings with user-options, we must do so after all of the
config is loaded. This is acceptable, as the resulting
conditionals are about setting variables specific to the
top-level Makefile (and if that ever changes, we can hoist
them into a separate post-config include, too).
