When adding objects for preferred delta base, the content from tree
objects leading to given paths is kept in a cache. This has the
potential to grow significantly, especially with large directories as
the whole tree object content is loaded in memory, even if in practice
the number of those objects is limited to the 256 cache entries plus the
$window root tree objects. Still, that can't hurt freeing that up after
object enumeration is done, and before more memory is needed for delta
search.

First of all, I can't find any reason why thin pack generation is
explicitly disabled when dealing with a shallow repository. The
possible delta base objects are collected from the edge commits which
are always obtained through history walking with the same shallow refs
as the client, Therefore the client is always going to have those base
objects available. So let's remove that restriction.
Then we can make shallow repository deepening much more efficient by
using the remote's unshallowed commits as edge commits to get preferred
base objects for thin pack generation. On git.git, this makes the data
transfer for the deepening of a shallow repository from depth 1 to depth 2
around 134 KB instead of 3.68 MB.

If all refs sent by the remote repo during a fetch are reachable
locally, then no further conversation is performed with the remote. This
check is skipped when the --depth argument is provided to allow the
deepening of a shallow clone which corresponding remote repo has no
changed.
However, some additional filtering was added in commit c29727d5 to
remove those refs which are equal on both sides. If the remote repo has
not changed, then the list of refs to give the remote process becomes
empty and simply attempting to deepen a shallow repo always fails.
Let's stop being smart in that case and simply send the whole list over
when that condition is met. The remote will do the right thing anyways.
Test cases for this issue are also provided.

Most of the docs and printouts refer to "commands" when discussing what
the end users call via the "git" top-level program. We should refer them
as "git programs" when we discuss the fact that the commands are
implemented as separate programs, but in other contexts, it is better to
use the term "git commands" consistently.

When making a histogram of delta chain length in the pack, the program
collects number of objects whose delta depth exceeds the MAX_CHAIN limit
in histogram[0], and showed it as the number of items that exceeds the
limit correctly. HOWEVER, it also showed the same number labeled as
"chain length = 0".
In fact, we are not showing the number of objects whose chain length is
zero, i.e. the base objects. Correct this.

Configuration values are expected to be quoted when they have leading or
trailing whitespace, but inner whitespace should be kept verbatim even if
the value is not quoted. This is already documented in git-config(1), but
the code caused inner whitespace to be collapsed to a single space,
breaking, for example, clones from a path that has two consecutive spaces
in it, as future fetches would only see a single space.

The second and third tests of this script expected that Russian strings
are converted between ISO-8859-5 and Shift_JIS in the "blame --porcelain"
format output correctly.
Sure, many platforms may convert between such a combination, but that is
only because one of the base character set of Shift_JIS, JIS X 0208,
defines codepoints for Russian characters (among others); I do not think
anybody uses Shift_JIS when seriously writing Russian, and it is perfectly
understandable if iconv() libraries on some platforms fail converting
between this combination, as it does not matter in reality.
This patch changes the test to verify Japanese strings are converted
correctly between EUC-JP and Shift_JIS in the same procedure. The point
of the test is not about verifying the platform's iconv() library, but to
see if "git blame" makes correct iconv() library calls when it should.
We could instead use ISO-8859-5 and KOI8-R as the combination, because
they are both meant to represent Russian, in order to make this test
meaningful on more platforms, but we already use Shift_JIS vs EUC-JP
combinations to test other programs in our test suite, so this combination
is safer from the point of view of the portability. Besides, I do not
read nor write Russian; sorry ;-)
This change allows tests to pass on my (friend's) Solaris 5.11 box.

The first "grep -C1" test in t7002 does not pass on my SunOS-5.11-i86pc,
and that is not because our way to spawn external grep is broken, but
because the native grep does not understand -C<n>.
It turns out that Peff was also using this option himself because our
Makefile doesn't do that automatically. Brandon Casey uses SUNWspro
compiler without having to set this, and it turns out that the compiler
does not define preprocessor macro __unix__ which made him always use the
built-in grep, never an external one.
Let's be more explicit and say that we do not use external grep on Suns.

'git branch' looks at _all_ the refs, and verifies them. Which means that
during cold-cache situations with a slow disk (and lots of tags, for
example) it can take several very annoying seconds (7.5s according to a
report by Carlos R. Mafra).
This avoids most of it by simply doing the filtering before looking up
the commits, by using the "raw" version of for_each_ref.

f8948e2 (remote prune: warn dangling symrefs, 2009-02-08) introduced a
more dangerous variant of for_each_ref() family that skips the check for
dangling refs, but it also made another unrelated check optional by
mistake.
The check to see if a ref points at 0{40} is not about brokenness, but is
about a possible future plan to represent a deleted ref by writing 40 "0"
in a loose ref when there is a stale version of the same ref already in
.git/packed-refs, so that we can implement deletion of a ref without
having to rewrite the packed refs file excluding the ref being deleted.
This check has to live outside of the conditional.

If a patch adds a new line to the end of a file and this line ends with
one trailing whitespace character and has no newline, then
'--whitespace=fix' currently does not remove that trailing whitespace.
This patch fixes this by removing the check for trailing whitespace at
the end of the line at a hardcoded offset which does not take the
eventual absence of newline into account.

When combine-diff inspected the diff from one parent to the merge result,
it misinterpreted a header in the form @@ -l,k +0,0 @@.
This hunk header means that K lines were removed from the beginning of the
file, so the lost lines must be queued to the sline that represents the
first line of the merge result, but we incremented our pointer incorrectly
and ended up queuing it to the second line, which in turn made the lossage
appear _after_ the first line.

For a deleted line in a patch with the parent we are looking at, the
append_lost() function finds the same line among a run of lines that were

checked. This is so that patches with two parents

can be coalesced into this sequence, reusing one line that describes the
removal of "two" for both parents.

While reading the second patch (that removes "two" and then "fyra"), after
finding where removal of the "two" matches, we need to find existing
removal of "fyra" (if exists) in the removal list, but the match has to
happen after all the existing matches (in this case "two"). The code used
a naïve O(n^2) algorithm to compute this by scanning the whole removal
list over and over again.
This patch remembers where the next scan should be started in the existing
removal list to avoid this.

When we switch branches with "checkout -f", unpack_trees() feeds two
cache_entries to oneway_merge() function in its src[] array argument. The
zeroth entry comes from the current index, and the first entry represents
what the merge result should be, taken from the tree recorded in the
commit we are switching to.
When we have a blob (either regular file or a symlink) in the index and in
the work tree at path "foo", and the switched-to tree has "foo/bar",
i.e. "foo" becomes a directory, src[0] is obviously that blob currently
registered at "foo". Even though we do not have anything at "foo" in the
switched-to tree, src[1] is _not_ NULL in this case.
The unpack_trees() machinery places a special marker df_conflict_entry
to signal that no blob exists at "foo", but it will become a directory
that may have somthing underneath it (namely "foo/bar"), so a usual 3-way
merge can notice the situation.
But oneway_merge() codepath failed to notice this and passed the special
marker directly to merged_entry(). This happens to remove the "foo" in
the end because the df_conflict_entry does not have any name (hence the
"error" message) and its addition in add_index_entry() is rejected, but it
is wrong.

When we fall back to a standard for_each_reflog_ent() after failing to find
the nth branch switch (or if we had a short reflog) with the call to
for_each_recent_reflog_ent(), we do not need to free the memory allocated
for our strbuf's since a strbuf_reset() will be performed in
grab_nth_branch_switch() before assigning to the entry.
Plus, the strbuf_release() negates the non-zero hint we initially gave to
strbuf_init() just above these lines.
