df58a8274d diff --quiet: make it synonym to --exit-code >/dev/null
The point of --quiet was to return the status as early as possible without
doing any extra processing.  Well behaved scripts, when they expect to run
many diff operations inside, are supposed to run "update-index --refresh"
upfront; we do not want them to pay the price of iterating over the index
and comparing the contents to fix the stat dirtiness, and we avoided most
of the processing in diffcore_std() when --quiet is in effect.

But scripts that adhere to the good practice won't have to pay any more
price than the necessary lstat(2) that will report stat cleanliness, as
long as only -q is given without any fancier diff options.

More importantly, users who do ask for "--quiet -M --filter=D" (in order
to notice only the deletion, not paths that disappeared only because they
have been renamed away) deserve to get the result they asked for, even it
means they have to pay the extra price; the alternative is to get a cheap
early return that gives a result they did not ask for, which is much
worse.

9d865356ab diff Porcelain: do not disable auto index refreshing on -C -C
When we enabled the automatic refreshing of the index to "diff" Porcelain,
we disabled it when --find-copies-harder was asked, but there is no good
reason to do so.  In the following command sequence, the first "diff"
shows an "empty" diff exposing stat dirtyness, while the second one does
not.

    $ >foo
    $ git add foo
    $ touch foo
    $ git diff -C -C
    $ git diff -C

This fixes the inconsistency.

a5a818ee48 diff: vary default prefix depending on what are compared
With a new configuration "diff.mnemonicprefix", "git diff" shows the
differences between various combinations of preimage and postimage trees
with prefixes different from the standard "a/" and "b/".  Hopefully this
will make the distinction stand out for some people.

    "git diff" compares the (i)ndex and the (w)ork tree;
    "git diff HEAD" compares a (c)ommit and the (w)ork tree;
    "git diff --cached" compares a (c)ommit and the (i)ndex;
    "git-diff HEAD:file1 file2" compares an (o)bject and a (w)ork tree entity;
    "git diff --no-index a b" compares two non-git things (1) and (2).

Because these mnemonics now have meanings, they are swapped when reverse
diff is in effect and this feature is enabled.

3928097020 diff: Help "less" hide ^M from the output
When the tracked contents have CRLF line endings, colored diff output
shows "^M" at the end of output lines, which is distracting, even though
the pager we use by default ("less") knows to hide them.

The problem is that "less" hides a carriage-return only at the end of the
line, immediately before a line feed.  The colored diff output does not
take this into account, and emits four element sequence for each line:

   - force this color;
   - the line up to but not including the terminating line feed;
   - reset color
   - line feed.

By including the carriage return at the end of the line in the second
item, we are breaking the smart our pager has in order not to show "^M".
This can be fixed by changing the sequence to:

   - force this color;
   - the line up to but not including the terminating end-of-line;
   - reset color
   - end-of-line.

where end-of-line is either a single linefeed or a CRLF pair.  When the
output is not colored, "force this color" and "reset color" sequences are
both empty, so we won't have this problem with or without this patch.

  Fix '--dirstat' with cross-directory renaming
  for-each-ref: Allow a trailing slash in the patterns
2008-08-29 00:16:39 -07:00
Linus Torvalds
441bca0bbc Fix '--dirstat' with cross-directory renaming
The dirstat code depends on the fact that we always generate diffs with
the names sorted, since it then just does a single-pass walk-over of the
sorted list of names and how many changes there were. The sorting means
that all files are nicely grouped by directory.

That all works fine.

Except when we have rename detection, and suddenly the nicely sorted list
of pathnames isn't all that sorted at all. And now the single-pass dirstat
walk gets all confused, and you can get results like this:

  [torvalds@nehalem linux]$ git diff --dirstat=2 -M v2.6.27-rc4..v2.6.27-rc5
     3.0% arch/powerpc/configs/
     6.8% arch/arm/configs/
     2.7% arch/powerpc/configs/
     4.2% arch/arm/configs/
     5.6% arch/powerpc/configs/
     8.4% arch/arm/configs/
     5.5% arch/powerpc/configs/
    23.3% arch/arm/configs/
     8.6% arch/powerpc/configs/
     4.0% arch/
     4.4% drivers/usb/musb/
     4.0% drivers/watchdog/
     7.6% drivers/
     3.5% fs/

The trivial fix is to add a sorting pass, fixing it to:

  [torvalds@nehalem linux]$ git diff --dirstat=2 -M v2.6.27-rc4..v2.6.27-rc5
    43.0% arch/arm/configs/
    25.5% arch/powerpc/configs/
     5.3% arch/
     4.4% drivers/usb/musb/
     4.0% drivers/watchdog/
     7.6% drivers/
     3.5% fs/

Spot the difference. In case anybody wonders: it's because of a ton of
renames from {include/asm-blackfin => arch/blackfin/include/asm} that just
totally messed up the file ordering in between arch/arm and arch/powerpc.

c35539eb10 diff --check: do not get confused by new blank lines in the middle
The code remembered that the last diff output it saw was an empty line,
and tried to reset that state whenever it sees a context line, a non-blank
new line, or a new hunk.  However, this codepath asks the underlying diff
engine to feed diff without any context, and the "just saw an empty line"
state was not reset if you added a new blank line in the last hunk of your
patch, even if it is not the last line of the file.

8a3f524bf2 xdiff-interface: hide the whole "xdiff_emit_state" business from the caller
This further enhances xdi_diff_outf() interface so that it takes two
common parameters: the callback function that processes one line at a
time, and a pointer to its application specific callback data structure.
xdi_diff_outf() creates its own "xdiff_emit_state" structure and stashes
these two away inside it, which is used by the lowest level output
function in the xdiff_outf() callchain, consume_one(), to call back to the
application layer.  With this restructuring, we lift the requirement that
the caller supplied callback data structure embeds xdiff_emit_state
structure as its first member.

2b6ca6df2d diff.renamelimit is a basic diff configuration
The configuration was added as a core option in 3299c6f (diff: make
default rename detection limit configurable., 2005-11-15), but 9ce392f
(Move diff.renamelimit out of default configuration., 2005-11-21)
separated diff-related stuff out of the core.

Up to that point it was Ok.

When we separated the Porcelain options out of the git_diff_config in
83ad63c (diff: do not use configuration magic at the core-level,
2006-07-08), we should have been more careful.

This mistake made diff-tree plumbing and git-show Porcelain to notice
different set of renames when the user explicitly asked for rename
detection.

6b2fbaaffc format-patch: Produce better output with --inline or --attach
This patch makes two small changes to improve the output of --inline
and --attach.

The first is to write a newline preceding the boundary. This is needed because
MIME defines the encapsulation boundary as including the preceding CRLF (or in
this case, just LF), so we should be writing one. Without this, the last
newline in the pre-diff content is consumed instead.

The second change is to always write the line termination character
(default: newline) even when using --inline or --attach. This is simply to
improve the aesthetics of the resulting message. When using --inline an email
client should render the resulting message identically to the non-inline
version. And when using --attach this adds a blank line preceding the
attachment in the email, which is visually attractive.

2006-06-22), but commit c1795bb0 (Unify whitespace checking, 2007-12-13)
changed it.  This patch restores the old behaviour.

Besides Linus' arguments in the log message of 50f575fc, resetting color
before printing newline is also important to keep 'git add --patch'
happy.  If the last line(s) of a file are removed, then that hunk will
end with a colored line.  However, if the newline comes before the color
reset, then the diff output will have an additional line at the end
containing only the reset sequence.  This causes trouble in
git-add--interactive.perl's parse_diff function, because @colored will
have one more element than @diff, and that last element will contain the
color reset.  The elements of these arrays will then be copied to @hunk,
but only as many as the number of elements in @diff.  As a result the
last color reset is lost and all subsequent terminal output will be
printed in color.

4d9b53591f avoid trailing whitespace in zero-change diffstat lines
In some cases, we produce a diffstat line even though no
lines have changed (e.g., because of an exact rename). In
this case, there is no +/- "graph" after the number of
changed lines. However, we output the space separator
unconditionally, meaning that these lines contained a
trailing space character.

This isn't a huge problem, but in cleaning up the output we
are able to eliminate some trailing whitespace from a test
vector.
