When we prepare the attribute stack for a lookup on a path,
we start with the cached stack from the previous lookup
(because it is common to do several lookups in the same
directory hierarchy). So the first thing we must do in
preparing the stack is to pop any entries that point to
directories we are no longer interested in.
For example, if our stack contains gitattributes for:
foo/bar/baz
foo/bar
foo
but we want to do a lookup in "foo/bar/bleep", then we want
to pop the top element, but retain the others.
To do this we walk down the stack from the top, popping
elements that do not match our lookup directory. However,
the test do this simply checked strncmp, meaning we would
mistake "foo/bar/baz" as a leading directory of
"foo/bar/baz_plus". We must also check that the character
after our match is '/', meaning we matched the whole path
component.
There are two special cases to consider:
1. The top of our attr stack has the empty path. So we
must not check for '/', but rather special-case the
empty path, which always matches.
2. Typically when matching paths in this way, you would
also need to check for a full string match (i.e., the
character after is '\0'). We don't need to do so in
this case, though, because our path string is actually
just the directory component of the path to a file
(i.e., we know that it terminates with "/", because the
filename comes after that).

estimate_cache_size() tries to guess how much memory is needed for the
in-memory representation of an index file. It does that by using the
file size, the number of entries and the difference of the sizes of the
on-disk and in-memory structs -- without having to check the length of
the name of each entry, which varies for each entry, but their sums are
the same no matter the representation.
Except there can be a difference. First of all, the size is really
calculated by ce_size and ondisk_ce_size based on offsetof(..., name),
not sizeof, which can be different. And entries are padded with 1 to 8
NULs at the end (after the variable name) to make their total length a
multiple of eight.
So in order to allocate enough memory to hold the index, change the
delta calculation to be based on offsetof(..., name) and round up to
the next multiple of eight.
On a 32-bit Linux, this delta was used before:
sizeof(struct cache_entry) == 72
sizeof(struct ondisk_cache_entry) == 64
---
8
The actual difference for an entry with a filename length of one was,
however (find the definitions are in cache.h):
offsetof(struct cache_entry, name) == 72
offsetof(struct ondisk_cache_entry, name) == 62
ce_size == (72 + 1 + 8) & ~7 == 80
ondisk_ce_size == (62 + 1 + 8) & ~7 == 64
---
16
So eight bytes less had been allocated for such entries. The new
formula yields the correct delta:
(72 - 62 + 7) & ~7 == 16

If the user gave us refspecs on the command line, we should use those
when deciding whether to prune a ref instead of relying on the
refspecs in the config.
Previously, running
git fetch --prune origin refs/heads/master:refs/remotes/origin/master
would delete every other ref under the origin namespace because we
were using the refspec to filter the available refs but using the
configured refspec to figure out if a ref had been deleted on the
remote. This is clearly the wrong thing to do.
Change prune_refs and get_stale_heads to simply accept a list of
references and a list of refspecs. The caller of either function needs
to decide what refspecs should be used to decide whether a ref is
stale.

I noticed this when "git am CORRUPTED" unexpectedly failed with an
odd diagnostic, and even removed one of the files it was supposed
to have patched.
Reproduce with any valid old/new patch from which you have removed
the "+++ b/FILE" line. You'll see a diagnostic like this
fatal: unable to write file '(null)' mode 100644: Bad address
and you'll find that FILE has been removed.
The above is on glibc-based systems. On other systems, rather than
getting "null", you may provoke a segfault as git tries to
dereference the NULL file name.

When core.ignorecase is true, the file globs configured in the
.gitattributes file should be matched case-insensitively against the paths
in the working directory. Let's do so.
Plus, add some tests.
The last set of tests is performed only on a case-insensitive filesystem.
Those tests make sure that git handles the case where the .gitignore file
resides in a subdirectory and the user supplies a path that does not match
the case in the filesystem. In that case^H^H^H^Hsituation, part of the
path supplied by the user is effectively interpreted case-insensitively,
and part of it is dependent on the setting of core.ignorecase. git will
currently only match the portion of the path below the directory holding
the .gitignore file according to the setting of core.ignorecase.
This is also partly future-proofing. Currently, git builds the attr stack
based on the path supplied by the user, so we don't have to do anything
special (like use strcmp_icase) to handle the parts of that path that don't
match the filesystem with respect to case. If git instead built the attr
stack by scanning the repository, then the paths in the origin field would
not necessarily match the paths supplied by the user. If someone makes a
change like that in the future, these tests will notice.

The previous logic in show_config was to print the delimiter when the
value was set, but Boolean variables have an implicit value "true" when
they appear with no value in the config file. As a result, we got:
git_Config --get-regexp '.*\.Boolean' #1. Ok: example.boolean
git_Config --bool --get-regexp '.*\.Boolean' #2. NO: example.booleantrue
Fix this by defering the display of the separator until after the value
to display has been computed.

Checking paths out of a tree is (currently) defined to do:
- Grab the paths from the named tree that match the given pathspec,
and add them to the index;
- Check out the contents from the index for paths that match the
pathspec to the working tree; and while at it
- If the given pathspec did not match anything, suspect a typo from the
command line and error out without updating the index nor the working
tree.
Suppose that the branch you are working on has dir/myfile, and the "other"
branch has dir/other but not dir/myfile. Further imagine that you have
either modified or removed dir/myfile in your working tree, but you have
not run "git add dir/myfile" or "git rm dir/myfile" to tell Git about your
local change. Running
$ git checkout other dir
would add dir/other to the index with the contents taken out of the
"other" branch, and check out the paths from the index that match the
pathspec "dir", namely, "dir/other" and "dir/myfile", overwriting your
local changes to "dir/myfile", even though "other" branch does not even
know about that file.
Fix it by updating the working tree only with the index entries that
was read from the "other" tree.

Mergetool now treats its path arguments as a pathspec (like other git
subcommands), restricting action to the given files and directories.
Files matching the pathspec are filtered so mergetool only acts on
unmerged paths; previously it would assume each path argument was in an
unresolved state, and get confused when it couldn't check out their
other stages.
Running "git mergetool subdir" will prompt to resolve all conflicted
blobs under subdir.

The threading tests turn on format.thread, but never clean
up after themselves, meaning that later tests will also have
format.thread set.
This is more annoying than most leftover config, too,
because not only does it impact the results of other tests,
but it does so non-deterministically. Threading requires the
generation of message-ids, which incorporate the current

The "git branch" command, while not in listing mode, calls create_branch()
even when the target branch already exists, and it does so even when it is
not interested in updating the value of the branch (i.e. the name of the
commit object that sits at the tip of the existing branch). This happens
when the command is run with "--set-upstream" option.
The earlier safety-measure to prevent "git branch -f $branch $commit" from
updating the currently checked out branch did not take it into account,
and we no longer can update the tracking information of the current branch.
Minimally fix this regression by telling the validation code if it is
called to really update the value of a potentially existing branch, or if
the caller merely is interested in updating auxiliary aspects of a branch.

Allow git-svn to populate the svn:mergeinfo property automatically in
a narrow range of circumstances. Specifically, when dcommitting a
revision with multiple parents, all but (potentially) the first of
which have been committed to SVN in the same repository as the target
of the dcommit.
In this case, the merge info is the union of that given by each of the
parents, plus all changes introduced to the first parent by the other
parents.
In all other cases where a revision to be committed has multiple
parents, cause "git svn dcommit" to raise an error rather than
completing the commit and potentially losing history information in
the upstream SVN repository.
This behavior is disabled by default, and can be enabled by setting
the svn.pushmergeinfo config option.
