7ceacdffc5 "blame -c" should be compatible with "annotate"
There is no reason to have a separate variable cmd_is_annotate;
OUTPUT_ANNOTATE_COMPAT option is supposed to produce the compatibility
output, and we should produce the same output even when the command was
not invoked as "annotate" but as "blame -c".

Noticed by Pasky.

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.

1b1dd23f2d Make usage strings dash-less
When you misuse a git command, you are shown the usage string.
But this is currently shown in the dashed form.  So if you just
copy what you see, it will not work, when the dashed form
is no longer supported.

This patch makes git commands show the dash-less version.

For shell scripts that do not specify OPTIONS_SPEC, git-sh-setup.sh

85af7929ee git-blame --reverse
This new option allows "git blame" to read an old version of the file, and
up to which commit each line survived (i.e. their children rewrote the
line out of the contents).  The previous revision machinery update to
decorate each commit with its children was leading to this change.  When
the --reverse option is given, we read the old version and pass blame to
the children of the current suspect, instead of the usual order of
starting from the latest and passing blame to parents.

The standard yardstick of "blame" in git.git history is "rev-list.c" which
was refactored heavily in its existence.  For example:

    git blame -C -C -w --reverse 9de48752..master -- rev-list.c

begins like this:

6c41b801 builtin-rev-list.c (JC Hamano   2008-04-02  1) #include "cache...

b1349229 rev-list.c         (LTorvalds   2005-07-26 13)    "usage: git-...

This reveals that the original first four lines survived until now in
builtin-rev-list.c , inclusion of "epoch.h" was removed after 213523f4
while the contents was still in rev-list.c.

This mode probably needs more tweaking so that the commit that removed the
line (i.e. the children of the commits listed in the above sample output)
is shown instead to be useful, but then there is a little matter of which
child of a fork point to show.

For now, you can find the diff that rewrote the fifth line above by doing:

    $ git log --children 213523f4^..

to find its child, which is 1025fe5 (Merge branch 'lt/rev-list' into next,
2006-03-01), and then look at that child with:

    $ git show 1025fe5

69264f46a1 builtin-blame.c: allow more than 16 parents
This removes the hardcoded 16 parents limit from git-blame by allowing the
parent array to be allocated dynamically.  As the ultimate objective is
not about allowing dodecapus, but about annotating the history upside
down, it also renames "parent" in the code to "scapegoat"; the name of the
game used to be "pass blame to your parents", but now it is "find a
scapegoat to pass blame on".

8e0f70033b Avoid unnecessary "if-before-free" tests.
This change removes all obvious useless if-before-free tests.
E.g., it replaces code like this:

        if (some_expression)
                free (some_expression);

with the now-equivalent:

        free (some_expression);

It is equivalent not just because POSIX has required free(NULL)
to work for a long time, but simply because it has worked for
so long that no reasonable porting target fails the test.
Here's some evidence from nearly 1.5 years ago:

    http://www.winehq.org/pipermail/wine-patches/2006-October/031544.html

FYI, the change below was prepared by running the following:

  git ls-files -z | xargs -0 \
  perl -0x3b -pi -e \
    's/\bif\s*\(\s*(\S+?)(?:\s*!=\s*NULL)?\s*\)\s+(free\s*\(\s*\1\s*\))/$2/s'

Note however, that it doesn't handle brace-enclosed blocks like
"if (x) { free (x); }".  But that's ok, since there were none like
that in git sources.

Beware: if you do use the above snippet, note that it can
produce syntactically invalid C code.  That happens when the
affected "if"-statement has a matching "else".
E.g., it would transform this

  if (x)
    free (x);
  else
    foo ();

into this:

  free (x);
  else
    foo ();

There were none of those here, either.

If you're interested in automating detection of the useless
tests, you might like the useless-if-before-free script in gnulib:
[it *does* detect brace-enclosed free statements, and has a --name=S
 option to make it detect free-like functions with different names]

  http://git.sv.gnu.org/gitweb/?p=gnulib.git;a=blob;f=build-aux/useless-if-before-free

  Remove one more (in imap-send.c), spotted by Jean-Luc Herren <jlh@gmx.ch>.

21e5ad50fc safecrlf: Add mechanism to warn about irreversible crlf conversions
CRLF conversion bears a slight chance of corrupting data.
autocrlf=true will convert CRLF to LF during commit and LF to
CRLF during checkout.  A file that contains a mixture of LF and
CRLF before the commit cannot be recreated by git.  For text
files this is the right thing to do: it corrects line endings
such that we have only LF line endings in the repository.
But for binary files that are accidentally classified as text the
conversion can corrupt data.

If you recognize such corruption early you can easily fix it by
setting the conversion type explicitly in .gitattributes.  Right
after committing you still have the original file in your work
tree and this file is not yet corrupted.  You can explicitly tell
git that this file is binary and git will handle the file
appropriately.

Unfortunately, the desired effect of cleaning up text files with
mixed line endings and the undesired effect of corrupting binary
files cannot be distinguished.  In both cases CRLFs are removed
in an irreversible way.  For text files this is the right thing
to do because CRLFs are line endings, while for binary files
converting CRLFs corrupts data.

This patch adds a mechanism that can either warn the user about
an irreversible conversion or can even refuse to convert.  The
mechanism is controlled by the variable core.safecrlf, with the
following values:

 - false: disable safecrlf mechanism
 - warn: warn about irreversible conversions
 - true: refuse irreversible conversions

The default is to warn.  Users are only affected by this default
if core.autocrlf is set.  But the current default of git is to
leave core.autocrlf unset, so users will not see warnings unless
they deliberately chose to activate the autocrlf mechanism.

The safecrlf mechanism's details depend on the git command.  The
general principles when safecrlf is active (not false) are:

 - we warn/error out if files in the work tree can modified in an
   irreversible way without giving the user a chance to backup the
   original file.

 - for read-only operations that do not modify files in the work tree
   we do not not print annoying warnings.

There are exceptions.  Even though...

 - "git add" itself does not touch the files in the work tree, the
   next checkout would, so the safety triggers;

 - "git apply" to update a text file with a patch does touch the files
   in the work tree, but the operation is about text files and CRLF
   conversion is about fixing the line ending inconsistencies, so the
   safety does not trigger;

 - "git diff" itself does not touch the files in the work tree, it is
   often run to inspect the changes you intend to next "git add".  To
   catch potential problems early, safety triggers.

The concept of a safety check was originally proposed in a similar
way by Linus Torvalds.  Thanks to Dimitry Potapov for insisting
on getting the naked LF/autocrlf=true case right.

7a51ed66f6 Make on-disk index representation separate from in-core one
This converts the index explicitly on read and write to its on-disk
format, allowing the in-core format to contain more flags, and be
simpler.

In particular, the in-core format is now host-endian (as opposed to the
on-disk one that is network endian in order to be able to be shared
across machines) and as a result we can dispense with all the
htonl/ntohl on accesses to the cache_entry fields.

This will make it easier to make use of various temporary flags that do
not exist in the on-disk format.

7c3c796295 blame: drop blob data after passing blame to the parent
We used to keep the blob data for each origin that has any remaining
line in the result, but this will get very costly with a huge file that
has a deep history.  This patch releases the blob after we ran diff
between the child rev and its parents.  When passing blame from a parent
to its parent (i.e. the grandparent), the blob data for the parent may
need to be read again, but it should be relatively cheap, thanks to
delta-base cache.

387e7e19d7 strbuf_read_file enhancement, and use it.
* make strbuf_read_file take a size hint (works like strbuf_read)
* use it in a couple of places.

663af3422a Full rework of quote_c_style and write_name_quoted.
* quote_c_style works on a strbuf instead of a wild buffer.
* quote_c_style is now clever enough to not add double quotes if not needed.

* write_name_quoted inherits those advantages, but also take a different
  set of arguments. Now instead of asking for quotes or not, you pass a
  "terminator". If it's \0 then we assume you don't want to escape, else C
  escaping is performed. In any case, the terminator is also appended to the
  stream. It also no longer takes the prefix/prefix_len arguments, as it's
  seldomly used, and makes some optimizations harder.

* write_name_quotedpfx is created to work like write_name_quoted and take
  the prefix/prefix_len arguments.

Thanks to those API changes, diff.c has somehow lost weight, thanks to the
removal of functions that were wrappers around the old write_name_quoted
trying to give it a semantics like the new one, but performing a lot of
allocations for this goal. Now we always write directly to the stream, no
intermediate allocation is performed.

As a side effect of the refactor in builtin-apply.c, the length of the bar
graphs in diffstats are not affected anymore by the fact that the path was
clipped.

f1696ee398 Strbuf API extensions and fixes.
* Add strbuf_rtrim to remove trailing spaces.
  * Add strbuf_insert to insert data at a given position.
  * Off-by one fix in strbuf_addf: strbuf_avail() does not counts the final
    \0 so the overflow test for snprintf is the strict comparison. This is
    not critical as the growth mechanism chosen will always allocate _more_
    memory than asked, so the second test will not fail. It's some kind of
    miracle though.
  * Add size extension hints for strbuf_init and strbuf_read. If 0, default
    applies, else:
      + initial buffer has the given size for strbuf_init.
      + first growth checks it has at least this size rather than the
        default 8192.

30b250104d Future-proof source for changes in xdemitconf_t
The instances of xdemitconf_t were initialized member by member.
Instead, initialize them to all zero, so we do not have
to update those places each time we introduce a new member.

[jc: minimally fixed by getting rid of a new global]

06f59e9f5d Don't fflush(stdout) when it's not helpful
This patch arose from a discussion started by Jim Meyering's patch
whose intention was to provide better diagnostics for failed writes.
Linus proposed a better way to do things, which also had the added
benefit that adding a fflush() to git-log-* operations and incremental
git-blame operations could improve interactive respose time feel, at
the cost of making things a bit slower when we aren't piping the
output to a downstream program.

This patch skips the fflush() calls when stdout is a regular file, or
if the environment variable GIT_FLUSH is set to "0".  This latter can
speed up a command such as:

GIT_FLUSH=0 strace -c -f -e write time git-rev-list HEAD | wc -l

a tiny amount.

b82871b3c3 git-blame -w: ignore whitespace
When refactoring code to split one iteration of a too deeply
nested loop into a separate function, it inevitably makes the
indentation levels shallower (that's the sole point of such a
refactoring).  With "git blame -w", you can ignore such
re-indentation and pass blame for such moved lines to the
parent.
