ecc03c1c6d Clarify documentation of "git checkout <tree-ish> paths" syntax
The SYNOPSIS section of the manual writes:

    git checkout [options] [<tree-ish>] [--] <paths>...

but the DESCRIPTION says that this form checks the paths out "from the
index, or from a named commit."  A later sentence refers to the same
argument as "<tree-ish> argument", but it is not clear that these two
sentences are talking about the same command line argument for first-time
readers.

b11b7e13f4 Add generic 'strbuf_readlink()' helper function
It was already what 'git apply' did in read_old_data(), just export it
as a real function, and make it be more generic.

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.

This is sort of a companion patch to 4723ee9(Close files opened by
lock_file() before unlinking.): on Windows, you cannot delete what
is still open.

This makes test 9300-fast-import pass on Windows for me; quite a few
fast-imports leave temporary packs until the test "blank lines not
necessary after other commands" actually tests for the number of files
in .git/objects/pack/, which has a few temporary packs now.

I guess that 8b4eb6b(Do not perform cross-directory renames when
creating packs) was "responsible" for the breakage.

If a file was removed in HEAD, but modified in MERGE_HEAD, recursive merge
will result in a "CONFLICT (delete/modify)". If the (now untracked) file
already exists and was not added to the index, it is overwritten with the
conflict resolution contents.

In similar situations (cf. test 2), the merge would abort with

"error: Untracked working tree 'file' would be overwritten by merge."

39c19ce275 gitweb: cache $parent_commit info in git_blame()
Luben Tuikov changed 'lineno' link from leading to commit which gave
current version of given block of lines, to leading to parent of this
commit in 244a70e (Blame "linenr" link jumps to previous state at
"orig_lineno").  This made possible data mining using 'blame' view.

The current implementation calls rev-parse once per each blamed line
to find parent revision of blamed commit, even when the same commit
appears more than once, which is inefficient.

This patch mitigates this issue by caching $parent_commit info in
%metainfo, which makes gitweb call rev-parse only once per each
unique commit in the output from "git blame".

In the tables below you can see simple benchmark comparing gitweb
performance before and after this patch

revision.c         | 15.9 |         4.32
gitweb/gitweb.perl | 14.7 |         4.71

As you can see the greater ratio of lines in file to unique commits
in blame output, the greater gain from the new implementation.

  Legend:

  [1] Number of lines:
      $ wc -l <file>
  [2] Number of unique commits in the blame output:
      $ git blame -p <file> | grep author-time | wc -l
  [3] Time for running "git blame -p" (user time, single run):
      $ time git blame -p <file> >/dev/null
  [4] Time to run gitweb as Perl script from command line:
      $ gitweb-run.sh "p=.git;a=blame;f=<file>" > /dev/null 2>&1

The gitweb-run.sh script includes slightly modified (with adjusted
pathnames) code from gitweb_run() function from the test script
t/t9500-gitweb-standalone-no-errors.sh; gitweb config file
gitweb_config.perl contents (again up to adjusting pathnames; in
particular $projectroot variable should point to top directory of git
repository) can be found in the same place.

Discussion
~~~~~~~~~~

A possible future improvement would be to open a bidi pipe to
"git cat-file --batch-check", (like in Git::Repo in gitweb caching by
Lea Wiemann), feed $long_rev^ to it, and parse its output, which is
in the following form:

  926b07e694599d86cec668475071b32147c95034 commit 637

This would mean one call to git-cat-file for the whole 'blame' view,
instead of one call to git-rev-parse per each unique commit in blame
output.

Yet another solution would be to change use of validate_refname() to
validate_revision() when checking script parameters (CGI query or
path_info), with validate_revision being something like the following:

  sub validate_revision {
        my $rev = shift;
        return validate_refname(strip_rev_suffixes($rev));
  }

so we don't need to calculate $long_rev^, but can pass "$long_rev^" as
'hb' parameter.

This solution has the advantage that it can be easily adapted to future
incremental blame output.

07e62b733f rebase: improve error messages about dirty state
If you have unstaged changes in your working tree and try to
rebase, you will get the cryptic "foo: needs update"
message, but nothing else.  If you have staged changes, you
get "your index is not up-to-date".

Let's improve this situation in two ways:

 - for unstaged changes, let's also tell them we are
   canceling the rebase, and why (in addition to the "needs
   update" lines)

 - for the staged changes case, let's use language that is a
   little more clear to the user: their index contains
   uncommitted changes

c74faea19e make sure packs to be replaced are closed beforehand
Especially on Windows where an opened file cannot be replaced, make
sure pack-objects always close packs it is about to replace. Even on
non Windows systems, this could save potential bad results if ever
objects were to be read from the new pack file using offset from the old
index.

This should fix t5303 on Windows.
