Duh.
When I did the object decorator thing, I made the "loop over the hash"
function use the same logic for updating the hash, ie made them use
if (++j >= size)
j = 0;
for both the hash update for both "insert" and "lookup"
HOWEVER.
For some inexplicable reason I had an extraneous
j++;
in the insert path (probably just from the fact that the old code there
used
j++;
if (j >= size)
j = 0;
and when I made them use the same logic I just didn't remove the old
extraneous line properly.
This fixes it.

Some users of fast-import have been trying to use it to rewrite
commits and trees, an activity where the all of the relevant blobs
are already available from the existing packfiles. In such a case
we don't want to repack a blob, even if the frontend application
has supplied us the raw data rather than a mark or a SHA-1 name.
I'm intentionally only checking the packfiles that existed when
fast-import started and am always ignoring all loose object files.
We ignore loose objects because fast-import tends to operate on a
very large number of objects in a very short timespan, and it is
usually creating new objects, not reusing existing ones. In such
a situtation the majority of the objects will not be found in the
existing packfiles, nor will they be loose object files. If the
frontend application really wants us to look at loose object files,
then they can just repack the repository before running fast-import.

The mess known as the progress meter in merge-recursive was my own
fault; I put it in thinking that we might be spending a lot of time
resolving unmerged entries in the index that were not handled by
the simple 3-way index merge code.
Turns out we don't really spend that much time there, so the progress
meter was pretty much always jumping to "(n/n) 100%" as soon as
the program started. That isn't a very good indication of progress.
Since I don't have a great solution for how a progress meter should
work here, I'm proposing we back it out entirely.

I'm using a variant of this update hook in a corporate environment
where we perform some validations of the commits and tags that
are being pushed. The model is a "central repository" type setup,
where users are given access to push to specific branches within
the shared central repository. In this particular installation we
run a specially patched git-receive-pack in setuid mode via SSH,
allowing all writes into the repository as the repository owner,
but only if this hook blesses it.
One of the major checks we perform with this hook is that the
'committer' line of a commit, or the 'tagger' line of a new annotated
tag actually correlates to the UNIX user who is performing the push.
Users can falsify these lines on their local repositories, but
the central repository that management trusts will reject all such
forgery attempts. Of course 'author' lines are still allowed to
be any value, as sometimes changes do come from other individuals.
Another nice feature of this hook is the access control lists for
all repositories on the system can also be stored and tracked in
a supporting Git repository, which can also be access controlled
by itself. This allows full auditing of who-had-what-when-and-why,
thanks to git-blame's data mining capabilities.

Alex Riesen noticed that the case where a file replaced a directory entry
in the working tree was broken on cygwin. It turns out that the code made
some Linux-specific assumptions, and also ignored errors entirely for the
case where the entry was a symlink rather than a file.
This cleans it up by separating out the common case into a function of its
own, so that both regular files and symlinks can share it, and by making
the error handling more obvious (and not depend on any Linux-specific
behaviour).

This updates the semantics of 'crlf' so that .gitattributes file
can say "this is text, even though it may look funny".
Setting the `crlf` attribute on a path is meant to mark the path
as a "text" file. 'core.autocrlf' conversion takes place
without guessing the content type by inspection.
Unsetting the `crlf` attribute on a path is meant to mark the
path as a "binary" file. The path never goes through line
endings conversion upon checkin/checkout.
Unspecified `crlf` attribute tells git to apply the
`core.autocrlf` conversion when the file content looks like
text.
Setting the `crlf` attribut to string value "input" is similar
to setting the attribute to `true`, but also forces git to act
as if `core.autocrlf` is set to `input` for the path.

- check if fsck ignores the subprojects: it just should give no errors
- check if commit in a subproject detected: make a commit in

- check if a changed subproject HEAD can be committed: try
"git-commit -a" in superproject. It should commit changed
HEAD of a subproject
- check if diff-index works for subproject elements: compare the index
(changed by previuos tests) with the initial commit (which created
two subprojects). Should show a change for the recently changed subproject
- check if diff-tree works for subproject elements: do the same, just use
git-diff-tree. This test is somewhat redundant, I just added it for

- check if git diff works for subproject elements: try to limit

git diff HEAD^ HEAD -- subproject
- check if clone works: try a clone of superproject and compare

Noticed by applying two diffs of different contexts to the same file.
The check for existence of a file was wrong: the test assumed it was
a directory and reset the errno (twice: directly and by calling
lstat). So if an entry existed and was _not_ a directory no attempt
was made to rename into it, because the errno (expected by renaming
code) was already reset to 0. This resulted in error:
fatal: unable to write file file mode 100644
For Linux, removing "errno = 0" is enough, as lstat wont modify errno
if it was successful. The behavior should not be depended upon,
though, so modify the "if" as well.
The test simulates this situation.

When no 'merge' attribute is given to a path, merge-recursive

Signed-off-by: Junio C Hamano <junkio@cox.net>
This allows users to specify custom low-level merge driver per
path, using the attributes mechanism. Just like you can specify
one of built-in "text", "binary", "union" low-level merge
drivers by saying:
* merge=text
.gitignore merge=union
*.jpg merge=binary
pick a name of your favorite merge driver, and assign it as the
value of the 'merge' attribute.
A custom low-level merge driver is defined via the config
mechanism. This patch introduces 'merge.driver', a multi-valued
configuration. Its value is the name (i.e. the one you use as
the value of 'merge' attribute) followed by a command line
specification. The command line can contain %O, %A, and %B to
be interpolated with the names of temporary files that hold the
common ancestor version, the version from your branch, and the
version from the other branch, and the resulting command is
spawned.
The low-level merge driver is expected to update the temporary
file for your branch (i.e. %A) with the result and exit with
status 0 for a clean merge, and non-zero status for a conflicted
merge.
A new test in t6026 demonstrates a sample usage.

This demonstrates how the new low-level per-path merge backends,

gitattribute mechanism.
Signed-off-by: Junio C Hamano <junkio@cox.net>
This allows 'merge' attribute to control how the file-level
three-way merge is done per path.
- If you set 'merge' to true, leave it unspecified, or set it
to "text", we use the built-in 3-way xdl-merge.
- If you set 'merge' to false, or set it to "binary, the
"binary" merge is done. The merge result is the blob from
'our' tree, but this still leaves the path conflicted, so
that the mess can be sorted out by the user. This is
obviously meant to be useful for binary files.
- 'merge=union' (this is the first example of a string valued
attribute, introduced in the previous one) uses the "union"
merge. The "union" merge takes lines in conflicted hunks
from both sides, which is useful for line-oriented files such
as .gitignore.
Instead fo setting merge to 'true' or 'false' by using 'merge'
or '-merge', setting it explicitly to "text" or "binary" will
become useful once we start allowing custom per-path backends to
be added, and allow them to be activated for the default
(i.e. 'merge' attribute specified to 'true' or 'false') case,
using some other mechanisms. Setting merge attribute to "text"
or "binary" will be a way to explicitly request to override such
a custom default for selected paths.
Currently there is no way to specify random programs but it
should be trivial for motivated contributors to add later.
There is one caveat, though. ll_merge() is called for both
internal ancestor merge and the outer "final" merge. I think an
interactive custom per-path merge backend should refrain from
going interactive when performing an internal merge (you can
tell it by checking call_depth) and instead just call either
ll_xdl_merge() if the content is text, or call ll_binary_merge()
otherwise.
