Update --porcelain argument to take optional version parameter
to allow multiple porcelain formats to be supported in the future.
The token "v1" is the default value and indicates the traditional
porcelain format. (The token "1" is an alias for that.)

Checking the version of the installed SVN libraries should not
require a git repository at all. This matches the behavior of

Add a test for "git svn help" for the same behavior while we're

"git pack-objects" and "git index-pack" mostly operate with off_t
when talking about the offset of objects in a packfile, but there
were a handful of places that used "unsigned long" to hold that
value, leading to an unintended truncation.
* nd/pack-ofs-4gb-limit:
fsck: use streaming interface for large blobs in pack
pack-objects: do not truncate result in-pack object size on 32-bit systems
index-pack: correct "offset" type in unpack_entry_data()
index-pack: report correct bad object offsets even if they are large
index-pack: correct "len" type in unpack_data()
sha1_file.c: use type off_t* for object_info->disk_sizep
pack-objects: pass length to check_pack_crc() without truncation

For blobs, we want to make sure the on-disk data is not corrupted
(i.e. can be inflated and produce the expected SHA-1). Blob content is
opaque, there's nothing else inside to check for.
For really large blobs, we may want to avoid unpacking the entire blob
in memory, just to check whether it produces the same SHA-1. On 32-bit
systems, we may not have enough virtual address space for such memory
allocation. And even on 64-bit where it's not a problem, allocating a
lot more memory could result in kicking other parts of systems to swap
file, generating lots of I/O and slowing everything down.
For this particular operation, not unpacking the blob and letting
check_sha1_signature, which supports streaming interface, do the job
is sufficient. check_sha1_signature() is not shown in the diff,
unfortunately. But if will be called when "data_valid && !data" is
false.
We will call the callback function "fn" with NULL as "data". The only
callback of this function is fsck_obj_buffer(), which does not touch
"data" at all if it's a blob.

A few tests that specifically target "git rebase -i" have been
added.

This new test case ensures that we handle commit messages that start
with fixup! or squash! followed by more than one space. While we do
not generate such messages when committing with --fixup/--squash, it
is perfectly legal for users to hand-craft their own fixup messages,
and we heed Postel's law by being lenient.

When rearranging the edit script, we happily mistake the comment
character for a command, and the command for a SHA-1. As a consequence,
when we move fixup! and squash! commits, our logic to skip lines with
already handled SHA-1s mistakenly skips anything but the first
commented-out pick line, too.
The upcoming rebase--helper patches will address this bug, therefore we
do not need to make the current autosquash code even more complex than
it already is, just to fix this bug.

For the upcoming rebase--helper work (which will accelerate the
interactive rebase noticably), it is important to verify that the
--gpg-sign option is handled properly.
Please note that this patch does this on the cheap, by verifying that
the expected option is printed in the message of the 'edit' operation.
We really should test that the interactive rebase signs the commits
properly, iff GPG is available. This test is left for later.

"git blame file" allowed the lineage of lines in the uncommitted,
unadded contents of "file" to be inspected, but it refused when
"file" did not appear in the current commit. When "file" was
created by renaming an existing file (but the change has not been
committed), this restriction was unnecessarily tight.

When blaming files, changes in the work tree are taken into account
and displayed as being "Not Committed Yet".
However, when blaming a file that is not known to the current HEAD,
git blame fails with `no such path 'foo' in HEAD`, even when the file
was git add'ed.
Allowing such a blame is useful when the new file added to the index
(not yet committed) was created by renaming an existing file. It
also is useful when the new file was created from pieces already in
HEAD, moved or copied from other files and blaming with copy
detection (i.e. "-C").

When "git fsck" reports a broken link (e.g. a tree object contains
a blob that does not exist), both containing object and the object
that is referred to were reported with their 40-hex object names.
The command learned the "--name-objects" option to show the path to
the containing object from existing refs (e.g. "HEAD~24^2:file.txt").
* js/fsck-name-object:
fsck: optionally show more helpful info for broken links

When reporting broken links between commits/trees/blobs, it would be
quite helpful at times if the user would be told how the object is
supposed to be reachable.
With the new --name-objects option, git-fsck will try to do exactly
that: name the objects in a way that shows how they are reachable.
For example, when some reflog got corrupted and a blob is missing that
should not be, the user might want to remove the corresponding reflog
entry. This option helps them find that entry: `git fsck` will now
report something like this:
broken link from tree b5eb6ff... (refs/stash@{<date>}~37:)
to blob ec5cf80...

If a subdirectory contains nothing but i-t-a entries, we generate an
empty tree object and add it to its parent tree. Which is wrong. Such
a subdirectory should not be added.
Note that this has a cascading effect. If subdir 'a/b/c' contains
nothing but i-t-a entries, we ignore it. But then if 'a/b' contains
only (the non-existing) 'a/b/c', then we should ignore 'a/b' while
building 'a' too. And it goes all the way up to top directory.

Commit 3cf773e (cache-tree: fix writing cache-tree when CE_REMOVE is
present - 2012-12-16) skips i-t-a entries when building trees objects
from the index. Unfortunately it may skip too much.
The code in question checks if an entry is an i-t-a one, then no tree
entry will be written. But it does not take into account that
directories can also be written with the same code. Suppose we have
this in the index.
a-file
subdir/file1
subdir/file2
subdir/file3
the-last-file
We write an entry for a-file as normal and move on to subdir/file1,
where we realize the entry name for this level is simply just
"subdir", write down an entry for "subdir" then jump three items ahead
to the-last-file.
That is what happens normally when the first file in subdir is not an
i-t-a entry. If subdir/file1 is an i-t-a, because of the broken
condition in this code, we still think "subdir" is an i-t-a file and
not writing "subdir" down and jump to the-last-file. The result tree
now only has two items: a-file and the-last-file. subdir should be
there too (even though it only records two sub-entries, file2 and
file3).
If the i-t-a entry is subdir/file2 or subdir/file3, this is not a
problem because we jump over them anyway. Which may explain why the
bug is hidden for nearly four years.
Fix it by making sure we only skip i-t-a entries when the entry in
question is actual an index entry, not a directory.

When the GPG prereq is not set, we do not run test 34. That
test changes the directory of the test script as a side
effect (something we usually frown on, but which matches the
style of the rest of this script). When test 35 (the
url-scrubbing test) runs, it expects to be in the directory
from test 34. If it's not, the test fails; we are in a
different sub-repo, our test-commit is built on a different
history, and the push becomes a non-fast-forward.
We can fix this by unconditionally moving to the directory
we expect (again, against our usual style but matching how
the rest of the script operates).
As an additional protection, let's also switch from "make a
new commit and push to master" to just "push to a new
branch". We don't care about the branch name; we just want
_some_ ref update to trigger the status output. Pushing to a
new branch is less likely to run into problems with
force-updates, changing the checked-out branch, etc.

Commit 47abd85 (fetch: Strip usernames from url's before
storing them, 2009-04-17) taught fetch to anonymize URLs.
The primary purpose there was to avoid sticking passwords in
merge-commit messages, but as a side effect, we also avoid
printing them to stderr.
The push side does not have the merge-commit problem, but it
probably should avoid printing them to stderr. We can reuse
the same anonymizing function.
Note that for this to come up, the credentials would have to
appear either on the command line or in a git config file,
neither of which is particularly secure. So people _should_
be switching to using credential helpers instead, which
makes this problem go away. But that's no excuse not to
improve the situation for people who for whatever reason end
up using credentials embedded in the URL.

When merge_recursive() decides what the correct blob object merge
result for a path should be, it uses update_file_flags() helper
function to write it out to a working tree file and then calls
add_cacheinfo(). The add_cacheinfo() function in turn calls
make_cache_entry() to create a new cache entry to replace the
higher-stage entries for the path that represents the conflict.
The make_cache_entry() function calls refresh_cache_entry() to fill
in the cached stat information. To mark a cache entry as
up-to-date, the data is re-read from the file in the working tree,
and goes through convert_to_git() conversion to be compared with the
blob object name the new cache entry records.
It is important to note that this happens while the higher-stage
entries, which are going to be replaced with the new entry, are
still in the index. Unfortunately, the convert_to_git() conversion
has a misguided "safer crlf" mechanism baked in, and looks at the
existing cache entry for the path to decide how to convert the
contents in the working tree file. If our side (i.e. stage#2)
records a text blob with CRLF in it, even when the system is
configured to record LF in blobs and convert them to CRLF upon
checkout (and back to LF upon checkin), the "safer crlf" mechanism
stops us doing so.
This especially poses a problem during a renormalizing merge, where
the merge result for the path is computed by first "normalizing" the
blobs involved in the merge by using convert_to_working_tree()
followed by convert_to_git() with "safer crlf" disabled. The merge
result that is computed correctly and fed to add_cacheinfo() via
update_file_flags() does _not_ match what refresh_cache_entry() sees
by converting the working tree file via convert_to_git().
We can work this around by not refreshing the new cache entry in
make_cache_entry() called by add_cacheinfo(). After add_cacheinfo()
adds the new entry, we can call refresh_cache_entry() on that,
knowing that addition of this new cache entry would have removed the
stale cache entries that had CRLF in stage #2 that were carried over
before the renormalizing merge started and will not interfere with
the correct recording of the result.
The test update was taken from a series by Torsten Bögershausen
that attempted to fix this with a different approach.

Before this change,
$ echo "* text=auto" >.gitattributes
$ echo "* eol=crlf" >>.gitattributes
would have the same effect as
$ echo "* text" >.gitattributes
$ git config core.eol crlf
Since the 'eol' attribute had higher priority than 'text=auto', this may
corrupt binary files and is not what most users expect to happen.
Make the 'eol' attribute to obey 'text=auto' and now
$ echo "* text=auto" >.gitattributes
$ echo "* eol=crlf" >>.gitattributes
behaves the same as
$ echo "* text=auto" >.gitattributes
$ git config core.eol crlf
In other words,
$ echo "* text=auto eol=crlf" >.gitattributes
has the same effect as
$ git config core.autocrlf true
and
$ echo "* text=auto eol=lf" >.gitattributes
has the same effect as
$ git config core.autocrlf input

When comparing two lines, ignoring any whitespace at the end, we first
try to match as many bytes as possible and break out of the loop only
upon mismatch, to let the remainder be handled by the code shared with
the other whitespace-ignoring code paths.
When comparing the bytes, however, we incremented the counters always,
even if the bytes did not match. And because we fall through to the
space-at-eol handling at that point, it is as if that mismatch never
happened.

The tests already set a variable called prefix and passed its value as
the first argument to this function. The old argument handling was
overwriting the global variable with its same value rather than creating
a local variable.
So change test_update_rejected to refer to the global variable rather
than taking the prefix as an argument.

Before committing ref updates, split symbolic ref updates into two
parts: an update to the underlying ref, and a log-only update to the
symbolic ref. This ensures that both references are locked correctly
during the transaction, including while their reflogs are updated.
Similarly, if the reference pointed to by HEAD is modified directly, add
a separate log-only update to HEAD, rather than leaving the job of
updating HEAD's reflog to commit_ref_update(). This change ensures that
HEAD is locked correctly while its reflog is being modified, as well as
being cheaper (HEAD only needs to be resolved once).
This makes use of a new function, lock_raw_ref(), which is analogous to
read_raw_ref(), but acquires a lock on the reference before reading it.
This change still has two problems:
* There are redundant read_ref_full() reference lookups.
* It is still possible to get incorrect reflogs for symbolic references
if there is a concurrent update by another process, since the old_oid
of a symref is determined before the lock on the pointed-to ref is
held.
Both problems will soon be fixed.

When renaming refs, don't dereference either the origin or the destination
before renaming.
The origin does not need to be dereferenced because it is presently
forbidden to rename symbolic refs.
Not dereferencing the destination fixes a bug where renaming on top of
a broken symref would use the pointed-to ref name for the moved
reflog.
Add a test for the reflog bug.

Add some tests checking that it is possible to work with a reference
even if there is an empty directory where the loose ref would be stored.
One of the new tests demonstrates a bug that has been with us since at
least 2.5.0--single reference lookup gives up when it sees the
directory, even if the reference exists as a packed ref. This probably
hasn't been reported before because Git usually cleans up empty
directories when packing references.
This bug will be fixed shortly.

Git-P4 used to place temporary refs under "git-p4-tmp". Since 3da1f37
Git checks that all refs are placed under "refs". Instruct Git-P4 to
place temporary refs under "refs/git-p4-tmp". There are no backwards
compatibility considerations as these refs are transient.
Use "git show-ref --verify" to check the (non-)existience of the refs
instead of file checks assuming the file-based ref backend.
All refs under "refs" are shared across all worktrees. This is not
desired for temporary Git-P4 refs and will be adressed in a later patch.
