  1. The original parsed the mailmap file itself, and it did
     it wrong (it did not understand entries with an extra
     email key).

     Instead, this version uses git's "%aE" and "%aN"
     formats to have git perform the mapping, meaning we do
     not have to read .mailmap at all, but still operate on
     the current state that git sees (and it also works
     properly from subdirs).

  2. The original would find multiple names for an email,
     but not the other way around.

     This version can do either or both. If we find multiple
     emails for a name, the resolution is less obvious than
     the other way around. However, it can still be a
     starting point for a human to investigate.

  3. The original would order only by count, not by recency.

     This version can do either. Combined with showing the
     counts, it can be easier to decide how to resolve.

  4. This version shows similar entries in a blank-delimited
     stanza, which makes it more clear which options you are
     picking from.

t4049: refocus tests

The primary thing Linus's patch wanted to change was to make sure
that 0-line change appears for a mode-only change.  Update the
first test to chmod a file that we can see in the output (limited
by --stat-count) to demonstrate it.  Also make sure to use test_chmod
and compare the index and the tree, so that we can run this test
even on a filesystem without permission bits.

Later two tests are about fixes to separate issues that were
introduced and/or uncovered by Linus's patch as a side effect, but
the issues are not related to mode-only changes.  Remove chmod from
the tests.

diff --stat: move the "total count" logic to the last loop

The diffstat generation logic, with --stat-count limit, is
implemented as three loops.

 - The first counts the width necessary to show stats up to
   specified number of entries, and notes up to how many entries in
   the data we need to iterate to show the graph;

 - The second iterates that many times to draw the graph, adjusts
   the number of "total modified files", and counts the total
   added/deleted lines for the part that was shown in the graph;

 - The third iterates over the remainder and only does the part to
   count "total added/deleted lines" and to adjust "total modified
   files" without drawing anything.

Move the logic to count added/deleted lines and modified files from
the second loop to the third loop.

This incidentally fixes a bug.  The third loop was not filtering
binary changes (counted in bytes) from the total added/deleted as it
should.  The second loop implemented this correctly, so if a binary
change appeared earlier than the --stat-count cutoff, the code
counted number of added/deleted lines correctly, but if it appeared
beyond the cutoff, the number of lines would have mixed with the
byte count in the buggy third loop.

Marc Khouzam [Fri, 23 Nov 2012 14:02:22 +0000 (09:02 -0500)]
Completion must sort before using uniq

The user can be presented with invalid completion results
when trying to complete a 'git checkout' command.  This can happen
when using a branch name prefix that matches multiple remote branches.

For example, if available branches are:
  master
  remotes/GitHub/maint
  remotes/GitHub/master
  remotes/origin/maint
  remotes/origin/master

When performing completion on 'git checkout ma' the user will be
given the choices:
  maint
  master

However, 'git checkout maint' will fail in this case, although
completion previously said 'maint' was valid.  Furthermore, when
performing completion on 'git checkout mai', no choices will be
suggested.  So, the user is first told that the branch name
'maint' is valid, but when trying to complete 'mai' into 'maint',
that completion is no longer valid.

The completion results should never propose 'maint' as a valid
branch name, since 'git checkout' will refuse it.

The reason for this bug is that the uniq program only
works with sorted input.  The man page states
"uniq prints the unique lines in a sorted file".

When __git_refs uses the guess heuristic employed by checkout for
tracking branches it wants to consider remote branches but only if
the branch name is unique.  To do that, it calls 'uniq -u'.  However
the input given to 'uniq -u' is not sorted.

Therefore, in the above example, when dealing with 'git checkout ma',
"__git_refs '' 1" will find the following list:
  master
  maint
  master
  maint
  master

which, when passed to 'uniq -u' will remain the same.  Therefore
'maint' will be wrongly suggested as a valid option.

When dealing with 'git checkout mai', the list will be:
  maint
  maint

which happens to be sorted and will be emptied by 'uniq -u',
properly ignoring 'maint'.

A solution for preventing the completion script from suggesting
such invalid branch names is to first call 'sort' and then 'uniq -u'.

keep mapped extensions together.

textconv feature. If the user has bothered to define a

on the textconv output, as that is what they will see in the
diff (and we do not even provide a mechanism for them to
search for binary needles that contain NUL characters).

diff_grep: use textconv buffers for add/deleted files

If you use "-G" to grep a diff, we will apply a configured
textconv filter to the data before generating the diff.
However, if the diff is an addition or deletion, we do not
bother running the diff at all, and just look for the token
in the added (or removed) content. This works because we
know that the diff must contain every line of content.

However, while we used the textconv-derived buffers in the
regular diff, we accidentally passed the original unmodified
buffers to regexec when checking the added or removed
content. This could lead to an incorrect answer.

Worse, in some cases we might have a textconv buffer but no
original buffer (e.g., if we pulled the textconv data from
cache, or if we reused a working tree file when generating
it). In that case, we could actually feed NULL to regexec
and segfault.
