When we introduced the "word diff" mode, we could have done one of three
things:
* change fn_out_consume() to "this is called every time a line worth of
diff becomes ready from the lower-level diff routine. This function
knows two sets of helpers (one for line-oriented diff, another for word
diff), and each set has various functions to be called at certain
places (e.g. hunk header, context, ...). The function's role is to
inspect the incoming line, and dispatch appropriate helpers to produce
either line- or word- oriented diff output."
* introduce fn_out_consume_word_diff() that is "this is called every time
a line worth of diff becomes ready from the lower-level diff routine,
and here is what we do to prepare word oriented diff using that line."
without touching fn_out_consume() at all.
* Do neither of the above, and keep fn_out_consume() to "this is called
every time a line worth of diff becomes ready from the lower-level diff
routine, and here is what we do to output line oriented diff using that
line." but sprinkle a handful of 'are we in word-diff mode? if so do
this totally different thing' at random places.
This patch is to at least abstract the details of "this totally different
thing" out from the main codepath, in order to improve readability.
We can later refactor it by introducing fn_out_consume_word_diff(), taking
the second route above, but that is a separate topic.

Commit b5227d8 changed the behavior of "ls-files" with
respect to includes, but accidentally broke the "-i" option
The original behavior was:
1. if no "-i" is given, cull all results according to --exclude*
2. if "-i" is given, show the inverse of (1)
The broken behavior was:
1. if no "-i" is given:
a. for "-o", cull results according to --exclude*
b. for index files, always show all
2. if "-i" is given:
a. for "-o", shows the inverse of (1a)
b. for index files, always show all
The fixed behavior keeps the new (1b) behavior introduced
by b5227d8, but fixes the (2b) behavior to show only ignored
files, not all files.
This patch also tweaks the documentation. The original text
was somewhat obscure in the first place, but it is also now
inaccurate (the relationship between (1b) and (2b) is not
quite a "reverse").

Colored word diff without context lines firstly printed all the hunk
headers among each other and then printed the diff.
This was due to the code relying on getting at least one context line at
the end of each hunk, where the colored words would be flushed (it is
done that way to be able to ignore rewrapped lines).

Although 'git help -a' actually doesn't need to be run inside a git
repository and uses no repository-specific information, it looks for a git
directory. On 'git <TAB><TAB>' the bash completion runs 'git help -a' and
unnecessary searching for a git directory can be annoying in auto-mount
environments. With this commit, 'git help' no longer searches for a
repository when run with the -a option.

When building Git with MSVC on Windows, directories named after the Git alias
are created for the output files, e.g. there is a "git-merge-index" directory
next to the "git-merge-index.exe" executable in the build root. Previously,
"make all" just checked if "git-merge-index" and "git-merge-index.exe" are the
same file, and if not, tried to remove "git-merge-index". This fails in the
case of "git-merge-index" being a directory, which is why this is checked now.

Usually we show deletion as a big hunk deleting all of the
file's text. However, for files with no content, the diff
shows just the 'deleted file mode ...' line. This patch
cause "add -p" (and related commands) to recognize that line
and explicitly ask about deleting the file.
We only add the "stage this deletion" hunk for empty files,
since other files will already ask about the big content
deletion hunk. We could also change those files to simply
display "stage this deletion", but showing the actual
deleted content is probably what an interactive user wants.

Currently, when there is an invalid command, the rest of the line is
still treated as if the command had been valid, i.e. rebase -i attempts

appear (the line was '.'; path to git-rebase-todo substituted):
Unknown command: .
fatal: ambiguous argument 'Please fix this in the file $somefile.':
unknown revision or path not in the working tree.
Use '--' to separate paths from revisions
fatal: Not a valid object name Please fix this in the file $somefile.

The docbook/xmlto toolchain insists on quoting ' as \'. This does
achieve the quoting goal, but modern 'man' implementations turn the
apostrophe into a unicode "proper" apostrophe (given the right
circumstances), breaking code examples in many of our manpages.
Quote them as \(aq instead, which is an "apostrophe quote" as per the
groff_char manpage.
Unfortunately, as Anders Kaseorg kindly pointed out, this is not
portable beyond groff, so we add an extra Makefile variable GNU_ROFF
which you need to enable to get the new quoting.
Thanks also to Miklos Vajna for documentation.

The loop in get_size_from_delta() feeds a deflated delta data from the
pack stream _until_ we get inflated result of 20 bytes[*] or we reach the
end of stream.
Side note. This magic number 20 does not have anything to do with the
size of the hash we use, but comes from 1a3b55c (reduce delta head
inflated size, 2006-10-18).
The loop reads like this:
do {
in = use_pack();
stream.next_in = in;
st = git_inflate(&stream, Z_FINISH);
curpos += stream.next_in - in;
} while ((st == Z_OK || st == Z_BUF_ERROR) &&
stream.total_out < sizeof(delta_head));
This git_inflate() can return:
- Z_STREAM_END, if use_pack() fed it enough input and the delta itself
was smaller than 20 bytes;
- Z_OK, when some progress has been made;
- Z_BUF_ERROR, if no progress is possible, because we either ran out of
input (due to corrupt pack), or we ran out of output before we saw the
end of the stream.
The fix b3118bd (sha1_file: Fix infinite loop when pack is corrupted,
2009-10-14) attempted was against a corruption that appears to be a valid
stream that produces a result larger than the output buffer, but we are
not even trying to read the stream to the end in this loop. If avail_out
becomes zero, total_out will be the same as sizeof(delta_head) so the loop
will terminate without the "fix". There is no fix from b3118bd needed for
this loop, in other words.
The loop in unpack_compressed_entry() is quite a different story. It
feeds a deflated stream (either delta or base) and allows the stream to
produce output up to what we expect but no more.
do {
in = use_pack();
stream.next_in = in;
st = git_inflate(&stream, Z_FINISH);
curpos += stream.next_in - in;
} while (st == Z_OK || st == Z_BUF_ERROR)
This _does_ risk falling into an endless interation, as we can exhaust
avail_out if the length we expect is smaller than what the stream wants to
produce (due to pack corruption). In such a case, avail_out will become
zero and inflate() will return Z_BUF_ERROR, while avail_in may (or may
not) be zero.
But this is not a right fix:
do {
in = use_pack();
stream.next_in = in;
st = git_inflate(&stream, Z_FINISH);
+ if (st == Z_BUF_ERROR && (stream.avail_in || !stream.avail_out)
+ break; /* wants more input??? */
curpos += stream.next_in - in;
} while (st == Z_OK || st == Z_BUF_ERROR)
as Z_BUF_ERROR from inflate() may be telling us that avail_in has also run
out before reading the end of stream marker. In such a case, both avail_in
and avail_out would be zero, and the loop should iterate to allow the end
of stream marker to be seen by inflate from the input stream.
The right fix for this loop is likely to be to increment the initial
avail_out by one (we allocate one extra byte to terminate it with NUL
anyway, so there is no risk to overrun the buffer), and break out if we
see that avail_out has become zero, in order to detect that the stream
wants to produce more than what we expect. After the loop, we have a
check that exactly tests this condition:
if ((st != Z_STREAM_END) || stream.total_out != size) {
free(buffer);
return NULL;
}
So here is a patch (without my previous botched attempts) to fix this
issue. The first hunk reverts the corresponding hunk from b3118bd, and
the second hunk is the same fix proposed earlier.

This is convenient when parsing multiple the blame of multiple files,
for example:
git ls-files -z --exclude-standard -- "*.[ch]" |
xargs --null -n 1 git blame -p > output
and then analyzing the 'output' file using a seperate script.
Currently the parsing is difficult when not all files have a newline
at EOF, this patch ensures that even such files have a newline at the
end of the blame output.
