If you have a change like:
-foo
+bar
we end up highlighting the entirety of both lines (since the
whole thing is changed). But the point of diff highlighting
is to pinpoint the specific change in a pair of lines that
are mostly identical. In this case, the highlighting is just
noise, since there is nothing to pinpoint, and we are better
off doing nothing.
The implementation looks for "interesting" pairs by checking
to see whether they actually have a matching prefix or
suffix that does not simply consist of colorization and
whitespace. However, the implementation makes it easy to
plug in other heuristics, too, like:
1. Depending on the source material, the set of "boring"
characters could be tweaked to include language-specific
stuff (like braces or semicolons for C).
2. Instead of saying "an interesting line has at least one
character of prefix or suffix", we could require that
less than N percent of the line be highlighted.
The simple "ignore whitespace, and highlight if there are
any matched characters" implemented by this patch seems to
give good results on git.git. I'll leave experimentation
with other heuristics to somebody who has a dataset that
does not look good with the current code.
Based on an original idea and implementation by Michał
Kiedrowicz.

When listing commands in zsh (git <TAB><TAB>), all of them will show up,
instead of only porcelain ones.
The root cause of this is because zsh versions from 4.3.0 to present
(4.3.15) do not correctly propagate the SH_WORD_SPLIT option into the
subshell in ${foo:=$(bar)} expressions. Because of this bug, the list of
all commands was treated as a single word in __git_list_porcelain_commands
and did not match any of the patterns that would usually cause plumbing to
be excluded.
With problematic versions of zsh, after running
emulate sh
fn () {
var='one two'
for v in $var; do echo $v; done
}
x=$(fn)
: ${y=$(fn)}
printing "$x" results in two lines as expected, but printing "$y" results
in a single line because $var is expanded as a single word when evaluating
fn to compute y.
So avoid the construct, and use an explicit 'test -n "$foo" || foo=$(bar)'
instead.

This simplifies svn-fe a great deal and fulfills a longstanding wish:
support for dumps with deltas in them, and incremental imports.
The cost is that commandline usage of the svn-fe tool becomes a little
more complicated since it no longer keeps state itself but instead reads
blobs back from fast-import in order to copy them between revisions and
apply deltas to them.
Also removes a couple of custom data structures and replaces them with
strbufs like other parts of Git.

zsh adds a backslash (foo\ ) for each item in the COMPREPLY array if IFS
doesn't contain spaces. This issue has been reported[1], but there is no
solution yet.
This wasn't a problem due to another bug[2], which was fixed in zsh
version 4.3.12. After this change, 'git checkout ma<tab>' would resolve
to 'git checkout master\ '.
Aditionally, the introduction of __gitcomp_nl in commit a31e626
(completion: optimize refs completion) in git also made the problem
apparent, as Matthieu Moy reported.
The simplest and most generic solution is to hide all the changes we do
to IFS, so that "foo \nbar " is recognized by zsh as "foo bar". This
works on versions of git before and after the introduction of
__gitcomp_nl (a31e626), and versions of zsh before and after 4.3.12.
Once zsh is fixed, we should conditionally disable this workaround to
have the same benefits as bash users.

To find out which is its parent the commit of the new branch is compared
sequentially to each blob of the parent branch from the newest to the
oldest. The first blob which results in a zero diff is considered the
parent commit. If none is found, then the commit is applied to the top
of the parent branch.
A fast-import "checkpoint" call is required because diff-tree is only
able to work with blobs on disk. But most of these commits will not be
part of the final imported tree, making fast-import fail. To avoid this,
the temporary branches are tracked and then removed at the end of the
import process.

We use the 'read' command without -r, so that it treats '\' as an
escape character, in several places. This breaks the loop reading
refnames from git-for-each-ref in __git_refs() if there are refnames
such as "foo'bar", in which case for-each-ref helpfully quotes them as
$ git update-ref "refs/remotes/test/foo'bar" HEAD
$ git for-each-ref --shell --format="ref=%(refname:short)" "refs/remotes"
ref='test/foo'\''bar'
Interpolating the \' here will read "ref='test/foo'''bar'" instead, and
eval then chokes on the unbalanced quotes.
However, since none of the read loops _want_ to have backslashes
interpolated, it's much safer to use read -r everywhere.

With this installed in your $PATH, you can store

The code is based in large part on the work of Jay Soffian,
who wrote the helper originally for the initial, unpublished
version of the credential helper protocol.
This version will pass t0303 if you do:
GIT_TEST_CREDENTIAL_HELPER=osxkeychain \
GIT_TEST_CREDENTIAL_HELPER_SETUP="export HOME=$HOME" \
./t0303-credential-external.sh

P4 only looks at the environment variable $PWD to figure out
where it is, so chdir() has code to set that every time. But
when the clone --destination is not an absolute path, PWD will
not be absolute and P4 won't be able to find any files expected
to be in the current directory. Fix this by expanding PWD to
an absolute path.
One place this crops up is when using a P4CONFIG environment
variable to specify P4 parameters, such as P4USER or P4PORT.
Setting P4CONFIG=.p4config works for p4 invocations from the
current directory. But if the value of PWD is not absolute, it
fails.
