Instead of warning the user that it is expecting git log output from
the standard input (and waiting for the user to type the log from
the keyboard, which is a silly thing to do), default to traverse from
HEAD when there is no rev parameter given and the standard input is
a tty.

This factors out a useful helper "add_head()" from builtin-diff.c to a
more appropriate place revision.c while renaming it to more descriptive
name add_head_to_pending(), as that is what the function is about.

The code tried to parse and clean-up the author name and the one line
information in three places (two callers of insert_author_oneline() and

This renames the callee to insert_one_record() and make it responsible
for cleaning up the author name and one line information.

The current method consists of a master thread serving chunks of objects
to work threads when they're done with their previous chunk.  The issue
is to determine the best chunk size: making it too large creates poor
load balancing, while making it too small has a negative effect on pack
size because of the increased number of chunk boundaries and poor delta
window utilization.

This patch implements a completely different approach by initially
splitting the work in large chunks uniformly amongst all threads, and
whenever a thread is done then it steals half of the remaining work from
another thread with the largest amount of unprocessed objects.

This has the advantage of greatly reducing the number of chunk boundaries
with an almost perfect load balancing.

It is currently sorted and then walked backward.  Not only this doesn't
feel natural for my poor brain, but it would make the next patch less
obvious as well.

So reverse the sort order, and reverse the list walking direction,
which effectively produce the exact same end result as before.

Also bring the relevant comment nearer the actual code and adjust it
accordingly, with minor additional clarifications.

Now that we are correctly removing leading prefixes from files in git
status, there is a degenerate case: the directory matching the prefix.
Because we show only the directory name for a directory that contains
only untracked files, it gets collapsed to an empty string.

Example:

  $ git init
  $ mkdir subdir
  $ touch subdir/file
  $ git status
  ...
  # Untracked files:
  #   (use "git add <file>..." to include in what will be committed)
  #
  #       subdir/

  So far, so good.

  $ cd subdir
  $ git status
  ....
  # Untracked files:
  #   (use "git add <file>..." to include in what will be committed)
  #
  #

  Oops, that's a bit confusing.

This teaches "git bisect visualize" to be more useful in non-windowed
environments.

 (1) When no option is given, and $DISPLAY is set, it continues to
     spawn gitk as before;

 (2) When no option is given, and $DISPLAY is unset, "git log" is run
     to show the range of commits between the bad one and the good ones;

 (3) If only "-flag" options are given, "git log <options>" is run.
     E.g. "git bisect visualize --stat"

 (4) Otherwise, all of the given options are taken as the initial part
     of the command line and the commit range expression is given to
     that command.  E.g. "git bisect visualize tig" will run "tig"
     history viewer to show between the bad one and the good ones.

As "visualize" is a bit too long to type, we also give it a shorter
synonym "view".

Rather than replicating the colorization logic of "git diff-files" we
rely on "git diff-files" itself. This guarantees consistent colorization
in and outside "git add -i".

Seeing as speed is not a concern here (the bottleneck is how fast the
user can read, not how fast "git diff-files" runs) we do this by
actually running it twice, once without color and once with.

In this way as the whitespace colorization provided by "git diff-files"
evolves (per-path attributes, new classes of whitespace error), "git
add -i" will automatically benefit from it and stay in synch.

Also, by working with two sets of diff output (an uncolorized one for
internal processing and a colorized one for display only) we minimize
the risk of regressions because the changes required to implement this
are minimally invasive.

9.x series; this should be good for at least a couple of years, when
Darwin 10 comes out and we can invert the sense of the test to

Consistently with all other diff oriented commands, we have given paths
relative to the work tree root in git-status output for a long time.
This documents the recent behaviour change, as people's eyes (and worse
yet, scripts, although scripts should not parse "git status" output) may
depend on the old behaviour.

In the longer run, giving a --full-name option to git-diff Porcelain
similar to what ls-files has, and change the default for git-diff
Porcelain to show relative paths may be a good thing to do, in order to
hide the oddballness of this git-status behaviour, but that would have a
rather large impact to established expectation by existing users.

The code calls fetch_pack() to get the list of refs it fetched, and
discards refs and always returns 0 to signal success.

But builtin-fetch-pack.c::fetch_pack() has error cases.  The function
returns NULL if error is detected (shallow-support side seems to choose
to die but I suspect that is easily fixable to error out as well).

Make fetch_refs_via_pack() propagate that error to the caller.

for-each-ref can accept only one quoting style. For this reason it uses
OPT_BIT for the quoting style switches so that it is easy to check for
more than one bit being set. However, not all symbolic constants were
actually single bit values. In particular:

    $ git for-each-ref --python
    error: more than one quoting style ?

This fixes it.

Mark Drago had a subversion repository which was then converted to hg
and now is moving in to git.  The first commit in the svn repo was
just the creation of the empty directory.  This made its way in to the
hg repository fine, but converting from hg to git would cause an
error.  The problem was that hg-to-git.py tries to commit the change,
git-commit fails, and then hg-to-git.py tries to checkout the new
revision and that fails (because it was not created).  This may have
only caused an error because it was the first commit in the
repository.  If an empty directory was added in the middle of the repo
somewhere things might have worked out fine.

This patch will use the new --allow-empty option to git-commit to
record such an "empty" commit, to reproduce the history recorded in hg
more faithfully.

This is mostly lifted from earlier series by Dan Zwell, but updated to
use "git config --get-color" and "git config --get-colorbool" to make it
simpler and more consistent with commands written in C.

A new configuration color.interactive variable is like color.diff and
color.status, and controls if "git-add -i" uses color.

A set of configuration variables, color.interactive.<slot>, are used to
define what color is used for the prompt, header, and help text.

For perl scripts, Git.pm provides $repo->get_color() method, which takes
the slot name and the default color, and returns the terminal escape
sequence to color the output text.  $repo->get_colorbool() method can be
used to check if color is set to be used for a given operation.

This adds an option to help scripts find out color settings from
the configuration file.

    git config --get-colorbool color.diff

inspects color.diff variable, and exits with status 0 (i.e. success) if
color is to be used.  It exits with status 1 otherwise.

If a script wants "true"/"false" answer to the standard output of the
command, it can pass an additional boolean parameter to its command
line, telling if its standard output is a terminal, like this:

    git config --get-colorbool color.diff true

When called like this, the command outputs "true" to its standard output
if color is to be used (i.e. "color.diff" says "always", "auto", or
"true"), and "false" otherwise.
