POSIX.1 (pax) is pretty clear on this:
The chksum field shall be the ISO/IEC 646:1991 standard IRV
representation of the octal value of the simple sum of all octets
in the header logical record. Each octet in the header shall be
treated as an unsigned value. These values shall be added to an
unsigned integer, initialized to zero, the precision of which is
not less than 17 bits. When calculating the checksum, the chksum
field is treated as if it were all <space> characters.
so is GNU:

Commit 7f02f3d7 (completion: rename internal helpers _git and _gitk,
2012-05-19) renamed said functions to _main_git() and _main_gitk(),
respectively. By convention the name of our git-completion-specific
functions start with '_git' or '__git' prefix, so rename those
functions once again to put them back into our "namespace". Use the
two underscore prefix, because _git_main() could be mistaken for the
completion function of the (not yet existing) 'git main' command.

GIT-BUILD-OPTIONS defines PERL_PATH to be used in the test suite. Only a
few tests already actually use this variable when perl is needed. The
other test just call 'perl' and it might happen that the wrong perl
interpreter is used.
This becomes problematic on Windows, when the perl interpreter that is
compiled and installed on the Windows system is used, because this perl
interpreter might introduce some unexpected LF->CRLF conversions.
This patch makes sure that $PERL_PATH is used everywhere in the test suite
and that the correct perl interpreter is used.

In commit e01105 Linus introduced gitlinks to update-index. He explains
that he thinks it is not the right thing to replace a gitlink with
something else.
That commit is from the very first beginnings of submodule support.
Since then we have gotten a lot closer to being able to remove a
submodule without losing its history. This check prevents such a use
case, so I think this assumption has changed.
Additionally in the git add codepath we do not have such a check, so for
consistency reasons I think removing this check is the correct thing to
do.

Since v1.7.0-rc2~11 (git-svn: persistent memoization, 2010-01-30),
git-svn has maintained some private per-repository caches in
.git/svn/.caches to avoid refetching and recalculating some
mergeinfo-related information with every "git svn fetch".
These caches use the 'nstore' format from the perl core module
Storable, which can be read and written quickly and was designed for
transfer over the wire (the 'n' stands for 'network'). This format is
endianness-independent and independent of floating-point
representation.
Unfortunately the format is *not* independent of the perl version ---
new perl versions will write files that very old perl cannot read.
Worse, the format is not independent of the size of a perl integer.
So if you toggle perl's use64bitint compile-time option, then using
'git svn fetch' on your old repositories produces errors like this:
Byte order is not compatible at ../../lib/Storable.pm (autosplit
into ../../lib/auto/Storable/_retrieve.al) line 380, at
/usr/share/perl/5.12/Memoize/Storable.pm line 21
That is, upgrading perl to a version that uses use64bitint for the
first time makes git-svn suddenly refuse to fetch in existing
repositories. Removing .git/svn/.caches lets git-svn recover.
It's time to switch to a platform independent serializer backend with
better compatibility guarantees. This patch uses YAML::Any.
Other choices were considered:
- thawing data from Data::Dumper involves "eval". Doing that without
creating a security risk is fussy.
- the JSON API works on scalars in memory and doesn't provide a
standard way to serialize straight to disk.
YAML::Any is reasonably fast and has a pleasant API. In most
backends, LoadFile() reads the entire file into a scalar anyway and
converts it as a second step, but having an interface that allows the
deserialization to happen on the fly without a temporary is still a
comfort.
YAML::Any is not a core perl module, so we take care to use it when
and only when it is available. Installations without that module
should fall back to using Storable with all its quirks, keeping their
cache files in
.git/svn/.caches/*.db
Installations with YAML peacefully coexist by keeping a separate set
of cache files in
.git/svn/.caches/*.yaml.
In most cases, switching between is a one-time thing, so it doesn't
seem worth the complication to migrate existing caches.
The upshot: after this patch, as long as YAML::Any is installed you
can move your git repository between machines with different perl
installations and "git svn fetch" will work fine. If you do not have
YAML::Any, the behavior is unchanged (and in particular does not get
any worse).

The __gitdir function is duplicated between completion and prompt

them can be subtly broken depending on the order the user's shell
dot-sources them.
Leave a note to people who may want to touch one copy to make sure
they update the other one in sync. Hopefully this line would also

The code internally runs sort_in_topo_order() already; it is more clear
to spell it out in the option parsing phase, instead of adding a special
case in simplify_merges() function.
Most of our documentation is in a single directory, so using
linkgit:git-config[1] just generates a relative link in the
same directory. However, this is not the case with the API
documentation in technical/*, which need to refer to
git-config from the parent directory.
We can fix this by passing a special prefix attribute when building
in a subdirectory, and respecting that prefix in our linkgit
definitions.
We only have to modify the html linkgit definition. For
manpages, we can ignore this for two reasons:
1. we do not generate actual links to the file in
manpages, but instead just give the name and section of
the linked manpage
2. we do not currently build manpages for subdirectories,
only html

t1304 first runs setfacl as an experiment to see whether the
filesystem supports ACLs, and skips the remaining tests if
it does not. However, our setfacl run did not exercise the
ACLs very well, and some filesystems may support our initial
setfacl, but not the rest of the test.
In particular, some versions of ecryptfs will erroneously
apply the umask on top of an inherited directory ACL,
causing our tests to fail. Let's be more careful and make
sure both that we can read back the user ACL we set, and
that the inherited ACL is propagated correctly. The latter
catches the ecryptfs bug, but may also catch other bugs
(e.g., an implementation which does not handle inherited
ACLs at all).
Since we're making the setup more complex, let's move it
into its own test. This will hide the output for us unless
the user wants to run "-v" to see it (and we don't need to
bother printing anything about setfacl failing; the
remaining tests will properly print "skip" due to the
missing prerequisite).

When the origin URL of the superproject is itself relative, git submodule sync
configures the remote.origin.url configuration property of the submodule
with a path that is relative to the work tree of the superproject
rather than the work tree of the submodule.
To fix this an 'up_path' that navigates from the work tree of the submodule
to the work tree of the superproject needs to be prepended to the URL
otherwise calculated.
Correct handling of superproject origin URLs like foo, ./foo and ./foo/bar is
left to a subsequent patch since an additional change is required to handle
these cases.
The documentation of resolve_relative_url() is expanded to give a more thorough
description of the function's objective.
