Long time ago, the feature of "diff-tree --stdin" to take a commit and its
parents on one line was broken, and did not support the common:
git rev-list --parents $commits... -- $paths... |
git diff-tree --stdin -v -p
usage pattern by Porcelains properly. For diff-tree to talk sensibly
about commits, it needs to see commits, not just trees; the code was fixed
to take list of commits on the standard input in 1.2.0.
However we left the documentation stale for a long time, until Karl
Hasselström finally noticed it very recently.

The configuration was added as a core option in 3299c6f (diff: make
default rename detection limit configurable., 2005-11-15), but 9ce392f
(Move diff.renamelimit out of default configuration., 2005-11-21)
separated diff-related stuff out of the core.
Up to that point it was Ok.
When we separated the Porcelain options out of the git_diff_config in
83ad63c (diff: do not use configuration magic at the core-level,
2006-07-08), we should have been more careful.
This mistake made diff-tree plumbing and git-show Porcelain to notice
different set of renames when the user explicitly asked for rename
detection.

When running git submodule update -i, the "-i" is shifted before recursing

We used to set the TOPOSORT flag of commits during the topological
sorting, but we can just as well use the member "indegree" for it:
indegree is now incremented by 1 in the cases where the commit used
to have the TOPOSORT flag.
This is the same behavior as before, since indegree could not be
non-zero when TOPOSORT was unset.
Incidentally, this fixes the bug in show-branch where the 8th column
was not shown: show-branch sorts the commits in topological order,
assuming that all the commit flags are available for show-branch's
private matters.
But this was not true: TOPOSORT was identical to the flag corresponding
to the 8th ref. So the flags for the 8th column were unset by the
topological sorting.

A wildcard refspec is internally parsed into a refspec structure with src
and dst strings. Many parts of the code assumed that these do not include
the trailing "/*" when matching the wildcard pattern with an actual ref we
see at the remote. What this meant was that we needed to make sure not
just that the prefix matched, and also that a slash followed the part that
matched.
But a codepath that scans the result from ls-remote and finds matching
refs forgot to check the "matching part must be followed by a slash" rule.
This resulted in "refs/heads/b1" from the remote side to mistakenly match
the source side of "refs/heads/b/*:refs/remotes/b/*" refspec.
Worse, the refspec crafted internally by "git-clone", and a hardcoded
preparsed refspec that is used to implement "git-fetch --tags", violated
this "parsed widcard refspec does not end with slash" rule; simply adding
the "matching part must be followed by a slash" rule then would have
broken codepaths that use these refspecs.
This commit changes the rule to require a trailing slash to parsed
wildcard refspecs. IOW, "refs/heads/b/*:refs/remotes/b/*" is parsed as
src = "refs/heads/b/" and dst = "refs/remotes/b/". This allows us to
simplify the matching logic because we only need to do a prefixcmp() to
notice "refs/heads/b/one" matches and "refs/heads/b1" does not.

If a user passes "--template=", then our template parameter
is blank. Unfortunately, copy_templates() assumes it has at
least one character, and does all sorts of bad things like
reading from template[-1] and then proceeding to link all of
'/' into the .git directory.
This patch just checks for that condition in copy_templates
and aborts. As a side effect, this means that --template=
now has the meaning "don't copy any templates."

Makefile records paths to a few programs in GIT-BUILD-OPTIONS file. These
paths need to be quoted twice: once to protect specials from the shell
that runs the generated GIT-BUILD-OPTIONS file, and again to protect them
(and the first level of quoting itself) from the shell that runs the
"echo" inside the Makefile.

If we are trying to resolve deltas for a long delta chain composed
of multi-megabyte objects we can easily run into requiring 500M+
of memory to hold each object in the chain on the call stack while
we recurse into the dependent objects and resolve them.
We now use a simple delta cache that discards objects near the
bottom of the call stack first, as they are the most least recently
used objects in this current delta chain. If we recurse out of a
chain we may find the base object is no longer available, as it was
free'd to keep memory under the deltaBaseCacheLimit. In such cases
we must unpack the base object again, which will require recursing
back to the root of the top of the delta chain as we released that
root first.
The astute reader will probably realize that we can still exceed
the delta base cache limit, but this happens only if the most
recent base plus the delta plus the inflated dependent sum up to
more than the base cache limit. Due to the way patch_delta is
currently implemented we cannot operate in less memory anyway.

If we free the data stored within a base_data we need the struct
object_entry to get the data back again for use with another dependent
delta. Storing the object_entry* in base_data makes it simple to call
get_data_from_pack() to recover the compressed information.
This however means that we must add the missing base object to the end of
our packfile prior to calling resolve_delta() on each of the dependent
deltas. Adding the base first ensures we can read the base back from the
pack we are indexing, as if it had been included by the remote side.
