The human-readable author and committer name can be missing from
commits imported from foreign SCM interfaces. Make sure we parse
the "author" and "committer" line a bit more leniently and avoid
segfaulting by assuming the name always exists.

If a command is run with an absolute path as a pathspec inside a bare
repository, e.g. "rev-list HEAD -- /home", the code tried to run strlen()
on NULL, which is the result of get_git_work_tree(), and segfaulted. It
should just fail instead.
Currently the function returns NULL even inside .git/ in a repository
with a work tree, but that is a separate issue.

When parsing the config file, if there is a value that is
syntactically correct but unused, we generally ignore it.
This lets non-core porcelains store arbitrary information in
the config file, and it means that configuration files can
be shared between new and old versions of git (the old
versions might simply ignore certain configuration).
The one exception to this is color configuration; if we
encounter a color.{diff,branch,status}.$slot variable, we
die if it is not one of the recognized slots (presumably as
a safety valve for user misconfiguration). This behavior
has existed since 801235c (diff --color: use
$GIT_DIR/config, 2006-06-24), but hasn't yet caused a
problem. No porcelain has wanted to store extra colors, and
we once a color area (like color.diff) has been introduced,
we've never changed the set of color slots.
However, that changed recently with the addition of
color.diff.func. Now a user with color.diff.func in their
config can no longer freely switch between v1.6.6 and older
versions; the old versions will complain about the existence
of the variable.
This patch loosens the check to match the rest of
git-config; unknown color slots are simply ignored. This
doesn't fix this particular problem, as the older version
(without this patch) is the problem, but it at least
prevents it from happening again in the future.

* jk/maint-add-p-delete-fix:
add-interactive: fix deletion of non-empty files
|
|
Commit 24ab81a fixed the deletion of empty files, but broke
deletion of non-empty files. The approach it took was to
factor out the "deleted" line from the patch header into its
own hunk, the same way we do for mode changes. However,
unlike mode changes, we only showed the special "delete this
file" hunk if there were no other hunks. Otherwise, the user
would annoyingly be presented with _two_ hunks: one for
deleting the file and one for deleting the content.
This meant that in the non-empty case, we forgot about the
deleted line entirely, and we submitted a bogus patch to
git-apply (with "/dev/null" as the destination file, but not
marked as a deletion).
Instead, this patch combines the file deletion hunk and the
content deletion hunk (if there is one) into a single
deletion hunk which is either staged or not.

The existing code checked to make sure we were not in a bare
repository when doing a hard reset. However, we should take
this one step further, and make sure we are in a worktree.
Otherwise, we can end up munging files inside of '.git'.
Furthermore, we should do the same check for --merge resets,
which have the same properties. Actually, a merge reset of
HEAD^ would already complain, since further down in the code
we want a worktree. However, it is nicer to check up-front;
then we are sure we cover all cases ("git reset --merge"
would run, even though it wasn't doing anything) and we can
give a more specific message.
Add tests to t7103 to cover these cases and some missing ones.

The patch structure has def_name component that is used to validate the
sanity of a "diff --git" patch by checking pathnames that appear on the
patch header lines for consistency. The git_header_name() function is
used to compute this out of "diff --git a/... b/..." line, but the code
always stripped one level of prefix (i.e. "a/" and "b/"), without paying
attention to -p<n> option. Code in find_name() function that parses other
lines in the patch header (e.g. "--- a/..." and "+++ b/..." lines) however
did strip the correct number of leading paths prefixes, and the sanity
check between these computed values failed.
Teach git_header_name() to honor -p<n> option like find_name() function
does.

The t/t9700/test.pl script uses method invocation syntax when
using the Cwd module to determine the current working directory.
This fails on cygwin, since cygwin perl specifically checks for
any arguments to the cwd() function and croak()'s with the message
"Usage: Cwd::cwd()". (In perl v5.8.8 distribution, see the file
perl-5.8.8/cygwin/cygwin.c lines 139-157)
In order to avoid the problem, we replace the method invocation
syntax with a simple function call.

Some test scripts run Perl scripts as if they were git-* scripts, and
thus need to use the same perl that will be put in the shebang line of
git*.perl commands. $PERL_PATH therefore needs to be used instead of
a bare "perl".
The tests can fail if another perl is found in $PATH before the one
defined in $PERL_PATH.
Example test failure caused by this: the perl defined in $PERL_PATH has
Error.pm installed, and therefore the Git.pm's Makefile.PL doesn't install
the private copy. The perl from $PATH doesn't have Error.pm installed, and
all git*.perl scripts invoked during the test will fail loading Error.pm.

Once upon a time, format-patch would use its default stat
plus patch format only when no diff format was given on the
command line. This meant that "format-patch -p" would
suppress the stat and show just the patch.
Commit 68daa64 changed this to keep the stat format when we
had an "implicit" patch format, like "-U5". As a side
effect, this meant that an explicit patch format was now
ignored (because cmd_format_patch didn't know the reason
that the format was set way down in diff_opt_parse).
This patch unbreaks what 68daa64 did (while still preserving
what 68daa64 was trying to do), reinstating "-p" to suppress
the default behavior. We do this by parsing "-p" ourselves
in format-patch, and noting whether it was used explicitly.

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).

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.

Some types of corruption to a pack may confuse the deflate stream
which stores an object. In Andy's reported case a 36 byte region
of the pack was overwritten, leading to what appeared to be a valid
deflate stream that was trying to produce a result larger than our
allocated output buffer could accept.
Z_BUF_ERROR is returned from inflate() if either the input buffer
needs more input bytes, or the output buffer has run out of space.
Previously we only considered the former case, as it meant we needed
to move the stream's input buffer to the next window in the pack.
We now abort the loop if inflate() returns Z_BUF_ERROR without
consuming the entire input buffer it was given, or has filled
the entire output buffer but has not yet returned Z_STREAM_END.
Either state is a clear indicator that this loop is not working
as expected, and should not continue.
This problem cannot occur with loose objects as we open the entire
loose object as a single buffer and treat Z_BUF_ERROR as an error.

In all parts of git, .gitignore and other exclude files
impact only how we treat untracked files; they should have
no effect on files listed in the index.
This behavior was originally implemented very early on in
9ff768e, but only for --exclude-from. Later, commit 63d285c
accidentally caused us to trigger the behavior for
--exclude-per-directory.
This patch totally ignores excludes for files found in the
index. This means we are reversing the original intent of
9ff768e, while at the same time fixing the accidental
behavior of 63d285c. This is a good thing, though, as the
way that 9ff768e behaved does not really make sense with the
way exclusions are used in modern git.
