This adds "attribute macros" (for lack of better name). So far,
we have low-level attributes such as crlf and diff, which are
defined in operational terms --- setting or unsetting them on a
particular path directly affects what is done to the path. For
example, in order to decline diffs or crlf conversions on a
binary blob, no diffs on PostScript files, and treat all other
files normally, you would have something like these:
* diff crlf
*.ps !diff
proprietary.o !diff !crlf
That is fine as the operation goes, but gets unwieldy rather
rapidly, when we start adding more low-level attributes that are
defined in operational terms. A near-term example of such an
attribute would be 'merge-3way' which would control if git
should attempt the usual 3-way file-level merge internally, or
leave merging to a specialized external program of user's
choice. When it is added, we do _not_ want to force the users
to update the above to:
* diff crlf merge-3way
*.ps !diff
proprietary.o !diff !crlf !merge-3way
The way this patch solves this issue is to realize that the
attributes the user is assigning to paths are not defined in
terms of operations but in terms of what they are.
All of the three low-level attributes usually make sense for
most of the files that sane SCM users have git operate on (these
files are typically called "text'). Only a few cases, such as
binary blob, need exception to decline the "usual treatment
given to text files" -- and people mark them as "binary".
So this allows the $GIT_DIR/info/alternates and .gitattributes
at the toplevel of the project to also specify attributes that
assigns other attributes. The syntax is '[attr]' followed by an
attribute name followed by a list of attribute names:
[attr] binary !diff !crlf !merge-3way
When "binary" attribute is set to a path, if the path has not
got diff/crlf/merge-3way attribute set or unset by other rules,
this rule unsets the three low-level attributes.
It is expected that the user level .gitattributes will be
expressed mostly in terms of attributes based on what the files
are, and the above sample would become like this:
(built-in attribute configuration)
[attr] binary !diff !crlf !merge-3way
* diff crlf merge-3way
(project specific .gitattributes)
proprietary.o binary
(user preference $GIT_DIR/info/attributes)
*.ps !diff
There are a few caveats.
* As described above, you can define these macros only in
$GIT_DIR/info/attributes and toplevel .gitattributes.
* There is no attempt to detect circular definition of macro
attributes, and definitions are evaluated from bottom to top
as usual to fill in other attributes that have not yet got
values. The following would work as expected:
[attr] text diff crlf
[attr] ps text !diff
*.ps ps
while this would most likely not (I haven't tried):
[attr] ps text !diff
[attr] text diff crlf
*.ps ps
* When a macro says "[attr] A B !C", saying that a path does
not have attribute A does not let you tell anything about
attributes B or C. That is, given this:
[attr] text diff crlf
[attr] ps text !diff
*.txt !ps
path hello.txt, which would match "*.txt" pattern, would have
"ps" attribute set to zero, but that does not make text
attribute of hello.txt set to false (nor diff attribute set to
true).

This is in the same spirit as the previous one. Earlier 'diff'
meant 'do the built-in binary heuristics and disable patch text
generation based on it' while '!diff' meant 'do not guess, do
not generate patch text'. There was no way to say 'do generate
patch text even when the heuristics says it has NUL in it'.

Earlier we said 'crlf lets the path go through core.autocrlf
process while !crlf disables it altogether'. This fixes the
semantics to:
- Lack of 'crlf' attribute makes core.autocrlf to apply
(i.e. we guess based on the contents and if platform
expresses its desire to have CRLF line endings via
core.autocrlf, we do so).
- Setting 'crlf' attribute to true forces CRLF line endings in
working tree files, even if blob does not look like text
(e.g. contains NUL or other bytes we consider binary).
- Setting 'crlf' attribute to false disables conversion.

The same way we generate diffs on symlinks as the the diff of text of the
symlink, we can generate subproject diffs (when not recursing into them!)
as the diff of the text that describes the subproject.
Of course, since what descibes a subproject is just the SHA1, that's what
we'll use. Add some pretty-printing to make it a bit more obvious what is
going on, and we're done.
So with this, we can get both raw diffs and "textual" diffs of subproject
changes:
- git diff --raw:
:160000 160000 2de597b5ad348b7db04bd10cdd38cd81cbc93ab5 0000000... M sub-A
- git diff:
diff --git a/sub-A b/sub-A
index 2de597b..e8f11a4 160000
--- a/sub-A
+++ b/sub-A
@@ -1 +1 @@
-Subproject commit 2de597b5ad348b7db04bd10cdd38cd81cbc93ab5
+Subproject commit e8f11a45c5c6b9e2fec6d136d3fb5aff75393d42
NOTE! We'll also want to have the ability to recurse into the subproject
and actually diff it recursively, but that will involve a new command line
option (I'd suggest "--subproject" and "-S", but the latter is in use by
pickaxe), and some very different code.
But regardless of ay future recursive behaviour, we need the non-recursive
version too (and it should be the default, at least in the absense of
config options, so that large superprojects don't default to something
extremely expensive).

Since "git ls-files" doesn't really pass down any details on what it
really wants done to the directory walking code, the directory walking
code doesn't really know whether the caller wants to know about gitlink
directories, or whether it wants to just know about ignored files.
So the directory walking code will return those gitlink directories unless
the caller has explicitly told it not to ("dir->show_other_directories"
tells the directory walker to only show "other" directories).
This kind of confuses "git ls-files -o", because
- it didn't really expect to see entries listed that were already in the
index, unless they were unmerged, and would die on that unexpected
setup, rather than just "continue".
- it didn't know how to match directory entries with the final "/"
This trivial change updates the "show_other_files()" function to handle
both of these issues gracefully. There really was no reason to die, when
the obviously correct thing for the function was to just ignore files it
already knew about (that's what "other" means here!).

This defines the semantics of 'crlf' attribute as an example.
When a path has this attribute unset (i.e. '!crlf'), autocrlf
line-end conversion is not applied.
Eventually we would want to let users to build a pipeline of
processing to munge blob data to filesystem format (and in the
other direction) based on combination of attributes, and at that
point the mechanism in convert_to_{git,working_tree}() that
looks at 'crlf' attribute needs to be enhanced. Perhaps the
existing 'crlf' would become the first step in the input chain,
and the last step in the output chain.

This adds the basic infrastructure to assign attributes to
paths, in a way similar to what the exclusion mechanism does
based on $GIT_DIR/info/exclude and .gitignore files.
An attribute is just a simple string that does not contain any
whitespace. They can be specified in $GIT_DIR/info/attributes
file, and .gitattributes file in each directory.
Each line in these files defines a pattern matching rule.
Similar to the exclusion mechanism, a later match overrides an
earlier match in the same file, and entries from .gitattributes
file in the same directory takes precedence over the ones from
parent directories. Lines in $GIT_DIR/info/attributes file are
used as the lowest precedence default rules.
A line is either a comment (an empty line, or a line that begins
with a '#'), or a rule, which is a whitespace separated list of
tokens. The first token on the line is a shell glob pattern.
The rest are names of attributes, each of which can optionally
be prefixed with '!'. Such a line means "if a path matches this
glob, this attribute is set (or unset -- if the attribute name
is prefixed with '!'). For glob matching, the same "if the
pattern does not have a slash in it, the basename of the path is
matched with fnmatch(3) against the pattern, otherwise, the path
is matched with the pattern with FNM_PATHNAME" rule as the
exclusion mechanism is used.
This does not define what an attribute means. Tying an
attribute to various effects it has on git operation for paths
that have it will be specified separately.

This series of three patches is a *replacement* for the patch series of
two patches (plus one-liner fixup) I sent yesterday.
It fixes the issue I noted with "git status" incorrectly
claiming that a non-checked out subproject wasn't clean - that
was just a total thinko in the code (we were checking the
filesystem mode against S_IFDIRLNK, which obviously cannot work,
since S_IFDIRLINK is a git-internal state, not a filesystem
state).
It then re-sends the two patches on top of that, with the fix
for checking out superprojects (we should *not* mess up any
existing subproject directories, certainly not remove them - if
we already have a directory in the place where we now want a
subproject, we should leave it well alone!)
The first one really is a fix, and it makes the commit
commentary about a remaining bug in the patch I sent out
yesterday go away.
This actually allows us to check out a supermodule after cloning, although
the submodules themselves will obviously not be checked out, and will just
be empty directories.

The code to match up index entries with the filesystem was stupidly
broken. We shouldn't compare the filesystem stat() information with
S_IFDIRLNK, since that's purely a git-internal value, and not what the
filesystem uses (on the filesystem, it's just a regular directory).
Also, don't bother to make the stat() time comparisons etc for DIRLNK
entries in ce_match_stat_basic(), since we do an exact match for these
things, and the hints in the stat data simply doesn't matter.
This fixes "git status" with submodules that haven't been checked out in
the supermodule.

This actually allows us to check out a supermodule after cloning, although

[ Side note: this also shows that we currently don't correctly handle
such subprojects that aren't checked out correctly yet. They should
always show up as not being modified, but failing to resolve the
gitlink HEAD does not properly trigger the "not modified" logic in all
places it needs to..
So more work to be done, but that's a separate issue, unrelated to
the action of checking out the superproject. ]
The bulk of this patch is simply because we need to check the type of the
index entry *before* we try to read the object it points to, and that
meant that the code needed some re-organization. So I moved some of the
code in common to both symlinks and files to be a trivial helper function.

I finally got around to looking at Alex' patch to teach update-index about
gitlinks too, so that "git commit -a" along with any other explicit
update-index scripts can work.
I don't think there was anything wrong with Alex' patch, but the code he
patched I felt was just so ugly that the added cases just pushed it over
the edge. Especially as I don't think that patch necessarily did the right
thing for a gitlink entry that already existed in the index, but that
wasn't actually a real git repository in the working tree (just an empty
subdirectory or a non-git snapshot because it hadn't wanted to track that
particular subproject).
So I ended up deciding to clean up the git-update-index handling the same
way I tackled the directory traversal used by git-add earlier: by
splitting the different cases up into multiple smaller functions, and just
making the code easier to read (and adding more comments about the
different cases).
So this replaces the old "process_file()" with a new "process_path()"
function that then just calls out to different helper functions depending
on what kind of path it is. Processing a nondirectory ends up being just
one of the simpler cases.
