fe549c21fc diff-lib: simplify do_diff_cache()
Since 34110cd (Make 'unpack_trees()' have a separate source and
destination index, 2008-03-06), we can run unpack_trees() without munging
the index at all, but do_diff_cache() tried ever so carefully to work
around the old behaviour of the function.

We can just tell unpack_trees() not to touch the original index and there
is no need to clean-up whatever the previous round has done.

ff00b682f2 reset [<commit>] paths...: do not mishandle unmerged paths
Because "diff --cached HEAD" showed an incorrect blob object name on the
LHS of the diff, we ended up updating the index entry with bogus value,
not what we read from the tree.

Noticed by John Nowak.

7d092adc8f get_pwd_cwd(): Do not trust st_dev/st_ino blindly
10c4c88 (Allow add_path() to add non-existent directories to the path,
2008-07-21) introduced get_pwd_cwd() function in order to favor $PWD when
getenv("PWD") and getcwd() refer to the same directory but are different
strings (e.g. the former gives a nicer looking name via a symbolic link to
an uglier looking automounted path). The function tried to determine if
two directories are the same by running stat(2) on both and comparing
ino/dev fields.

Unfortunately, stat() does not fill any ino or dev fields in msysgit.  But
there is a telltale: both ino and dev are 0 when they are not filled
correctly, so let's be extra cautious.

This happens to fix a bug in "get-receive-pack working_directory/" when
the GIT_DIR would not be set correctly due to absolute_path(".")
returning the wrong value.

1b4bb16b9e pack-objects: optimize "recency order"
This optimizes the "recency order" (see pack-heuristics.txt in
Documentation/technical/ directory) used to order objects within a
packfile in three ways:

 - Commits at the tip of tags are written together, in the hope that
   revision traversal done in incremental fetch (which starts by
   putting them in a revision queue marked as UNINTERESTING) will see a
   better locality of these objects;

 - In the original recency order, trees and blobs are intermixed. Write
   trees together before blobs, in the hope that this will improve
   locality when running pathspec-limited revision traversal, i.e.
   "git log paths...";

 - When writing blob objects out, write the whole family of blobs that use
   the same delta base object together, by starting from the root of the
   delta chain, and writing its immediate children in a width-first
   manner, in the hope that this will again improve locality when reading
   blobs that belong to the same path, which are likely to be deltified
   against each other.

I tried various workloads in the Linux kernel repositories (HEAD at
v3.0-rc6-71-g4dd1b49) packed with v1.7.6 and with this patch, counting how
large seeks are needed between adjacent accesses to objects in the pack,
and the result looks promising.  The history has 2072052 objects, weighing
some 490MiB.

   95% of the pack accesses look at data that is no further than 260kB

   With the current pack heuristics, more than 30% of accesses have to
   seek further than 300MB; the updated pack heuristics ensures that less
   than 0.1% of accesses have to seek further than 135MB. This is largely
   due to the fact that the updated heuristics does not mix blobs and
   trees together.

   The result is very similar to the pathspec-limited log above, which
   only looks at the tree objects.

 * Packing recent history.

   $ (git for-each-ref --format='^%(refname)' refs/tags; echo HEAD) |
     git pack-objects --revs --stdout >/dev/null

   This should pack data worth 71 commits.

       Less than 2MiB seek:       77.09%      99.04%

    The long-tail part of the result looks worse with the patch, but
    the change helps majority of the access. 99.04% of the accesses
    need less than 2MiB of seeking, compared to 77.09% with the current
    packing heuristics.

       Less than 2MiB seek:       81.73%      96.92%

   As the index-pack command already walks objects in the delta chain
   order, writing the blobs out in the delta chain order seems to
   drastically improve the locality of access.

Note that a half-a-gigabyte packfile comfortably fits in the buffer cache,
and you would unlikely to see much performance difference on a modern and
reasonably beefy machine with enough memory and local disks. Benchmarking
with cold cache (or over NFS) would be interesting.

823e0ded8a help_unknown_cmd: do not propose an "unknown" cmd
When executing an external shell script like `git foo` with a bad
shebang, e.g. "#!/usr/bin/not/existing", execvp returns 127 (ENOENT).

Since help_unknown_cmd proposes the use of all external commands similar
to the name of the "unknown" command, it suggests the just failed command
again. Stop it and give some advice to the user.

5f44324d88 core: log offset pack data accesses happened
In a workload other than "git log" (without pathspec nor any option that
causes us to inspect trees and blobs), the recency pack order is said to
cause the access jump around quite a bit. Add a hook to allow us observe
how bad it is.

"git config core.logpackaccess /var/tmp/pal.txt" will give you the log
in the specified file.

c5bcf1f9f6 checkout: do not write bogus reflog entry out
As resolve_ref() returns a static buffer that is local to the function,
the caller needs to be sure that it will not have any other calls to the
function before it uses the returned value, or store it away with a
strdup().  The code used old.path to record which branch it used to be on,
so that it can say between which branches the switch took place in the
reflog, but sometimes it failed to do so.

7791a1d9b9 Documentation: use [verse] for SYNOPSIS sections
The SYNOPSIS sections of most commands that span several lines already
use [verse] to retain line breaks. Most commands that don't span
several lines seem not to use [verse]. In the HTML output, [verse]
does not only preserve line breaks, but also makes the section
indented, which causes a slight inconsistency between commands that
use [verse] and those that don't. Use [verse] in all SYNOPSIS sections
for consistency.

Also remove the blank lines from git-fetch.txt and git-rebase.txt to
align with the other man pages. In the case of git-rebase.txt, which
already uses [verse], the blank line makes the [verse] not apply to
the last line, so removing the blank line also makes the formatting
within the document more consistent.

While at it, add single quotes to 'git cvsimport' for consistency with
other commands.

188c35e36d git skew: a tool to find how big a clock skew exists in the history
> As you probably guessed from the specificity of the number, I wrote a

This patch doesn't implement auto-detection of skew, but is the program
I used to calculate, and would provide the basis for such
auto-detection. It would be interesting to see average skew numbers for
popular repositories. You can run it as "git skew --all".

e8c3531717 gitweb: Serve */*+xml 'blob_plain' as text/plain with $prevent_xss
Enhance usability of 'blob_plain' view protection against XSS attacks
(enabled by setting $prevent_xss to true) by serving contents inline
as safe 'text/plain' mimetype where possible, instead of serving with
"Content-Disposition: attachment" to make sure they don't run in
gitweb's security domain.

This patch broadens downgrading to 'text/plain' further, to any
*/*+xml mimetype.  This includes:

  application/xhtml+xml    (*.xhtml, *.xht)
  application/atom+xml     (*.atom)
  application/rss+xml      (*.rss)
  application/mathml+xm    (*.mathml)
  application/docbook+xml  (*.docbook)
  image/svg+xml            (*.svg, *.svgz)

Probably most useful is serving XHTML files as text/plain in
'blob_plain' view, directly viewable.

Because file with 'image/svg+xml' mimetype can be compressed SVGZ
file, we have to check if */*+xml really is text file, via '-T $fd'.

86afbd02c8 gitweb: Serve text/* 'blob_plain' as text/plain with $prevent_xss
One of mechanism enabled by setting $prevent_xss to true is 'blob_plain'
view protection.  With XSS prevention on, blobs of all types except a
few known safe ones are served with "Content-Disposition: attachment" to
make sure they don't run in our security domain.

Instead of serving text/* type files, except text/plain (and including
text/html), as attachements, downgrade it to text/plain.  This way HTML
pages in 'blob_plain' (raw) view would be displayed in browser, but
safely as a source, and not asked to be saved.

4dca1aa650 git-submodule.sh: preserve stdin for the command spawned by foreach
The user-supplied command spawned by 'submodule foreach' loses its
connection to the original standard input.  Instead, it is connected to the
output of a pipe within the git-submodule script.  The user-supplied
command supplied to 'submodule foreach' is spawned within a while loop
which is being piped into.  Due to the way shells implement piping output
to a while loop, a subshell is created with its standard input attached to
the output of the pipe.  This results in all of the commands executed
within the while loop to have their stdins modified in the same way,
including the user-supplied command.

This can cause a problem if the command requires reading from stdin or if
it changes its behavior based on whether stdin is a tty or not.  For
example, this problem was noticed when trying to execute the following:

   git submodule foreach git shortlog --since=two.weeks.ago

which printed a message about entering the first submodule and produced no
further output and exited with a status of zero.  In this case, shortlog
detected that it was not connected to a tty, and since no revision was
supplied as an argument, it attempted to read the list of revisions from
standard input.  Instead, it slurped up the list of submodules that was
being piped to the enclosing while loop and caused that loop to end early
without processing the remaining submodules.

Work around this behavior by saving the original standard input file
descriptor before the while loop, and restoring it when spawning the
user-supplied command.

This fixes the tests in t7407.
