The patience diff algorithm produces slightly more intuitive output
than the classic Myers algorithm, as it does not try to minimize the
number of +/- lines first, but tries to preserve the lines that are
unique.
To this end, it first determines lines that are unique in both files,
then the maximal sequence which preserves the order (relative to both
files) is extracted.
Starting from this initial set of common lines, the rest of the lines
is handled recursively, with Myers' algorithm as a fallback when
the patience algorithm fails (due to no common unique lines).
This patch includes memory leak fixes by Pierre Habouzit.

git-sh-setup: Fix scripts whose PWD is a symlink into a git work-dir
I want directories of my working tree to be linked to from various
paths on my filesystem where third-party components expect them, both
in development and production environments. A build system's install
step could solve this, but I develop scripts and web pages that don't
need to be built. Git's submodule system could solve this, but we
tend to develop, branch, and test those directories all in unison, so
one big repository feels more natural. We prefer to edit and commit
on the symlinked paths, not the canonical ones, and in that setting,
"git pull" fails to find the top-level directory of the repository
while other commands work fine.
"git pull" fails because POSIX shells have a notion of current working
directory that is different from getcwd(). The shell stores this path
in PWD. As a result, "cd ../" can be interpreted differently in a
shell script than chdir("../") in a C program. The shell interprets
"../" by essentially stripping the last textual path component from
PWD, whereas C chdir() follows the ".." link in the current directory
on the filesystem. When PWD is a symlink, these are different
destinations. As a result, Git's C commands find the correct
top-level working tree, and shell scripts do not.
Changes:
* When interpreting a relative upward (../) path in cd_to_toplevel,
prepend the cwd without symlinks, given by /bin/pwd
* Add tests for cd_to_toplevel and "git pull" in a symlinked
directory that failed before this fix, plus contrasting scenarios
that already worked

It was already what 'git apply' did in read_old_data(), just export it

In particular, this handles the case of the lstat() st_size data not
matching the readlink() return value properly (which apparently happens
at least on NTFS under Linux). But as a result of this you could also
use the new function without even knowing how big the link is going to
be, and it will allocate an appropriately sized buffer.
So we pass in the st_size of the link as just a hint, rather than a
fixed requirement.

his way, showing a tag object that points to a bad object:
$ git show tag-foo
would give the error message to the pager. However, it was not quite
right if the user did:
$ git show 2>error.log tag-foo
i.e. use the pager but store the errors in a separate file.
When a tag points at a bad or nonexistent object, we should diagnose the
breakage and exit. An earlier commit 4f3dcc2 (Fix 'git show' on signed
tag of signed tag of commit, 2008-07-01) lost this check and made it
segfault instead; not good.

Currently we just skip rewrite diffs for binary files; this
patch makes an exception for files which will be textconv'd,
and actually performs the textconv before generating the
diff.
Conceptually, rewrite diffs should be in the exact same
format as the a non-rewrite diff, except that we refuse to
share any context. Thus it makes very little sense for "git
diff" to show a textconv'd diff, but for "git diff -B" to

The current emit_rewrite_diff code always writes a text patch without
checking whether the content is binary. This means that if you end up with
a rewrite diff for a binary file, you get lots of raw binary goo in your
patch.
Instead, if we have binary files, then let's just skip emit_rewrite_diff
altogether. We will already have shown the "dissimilarity index" line, so
it is really about the diff contents. If binary diffs are turned off, the
"Binary files a/file and b/file differ" message should be the same in
either case. If we do have binary patches turned on, there isn't much
point in making a less-efficient binary patch that does a total rewrite;
no human is going to read it, and since binary patches don't apply with
any fuzz anyway, the result of application should be the same.

find_parent_branch generates branch@rev type branches when one has to
look back through SVN history to properly get the history for a branch
copied from somewhere not already being tracked by git-svn. If in the
process of fetching this history, git-svn is interrupted, then when one
fetches again, it will use whatever was last fetched as the parent
commit and fail to fetch any more history which it didn't get to before
being terminated. This is especially troubling in that different
git-svn copies of the same SVN repository can end up with different
commit sha1s, incorrectly showing the history as divergent and
precluding easy collaboration using git push and fetch.
To fix this, when we initialise the Git::SVN object $gs to search for
and perhaps fetch history, we check if there are any commits in SVN in
the range between the current revision $gs is at, and the top revision
for which we were asked to fill history. If there are commits we're
missing in that range, we continue the fetch from the current revision
to the top, properly getting all history before using it as the parent
for the branch we're trying to create.
