Bash on Windows converts program arguments that look like absolute POSIX
paths to their Windows form, i.e., drive-letter-colon format. For this
reason, those tests in t1402 that check refs that begin with a slash do not
work as expected on Windows: valid_ref tests are doomed to fail, and
invalid_ref tests fail for the wrong reason (that there is a colon rather
than that they begin with a slash).
Skip these tests.

Move most of the code from read_bundle_header() to parse_bundle_header()
that takes a file descriptor that is already opened for reading, and make
the former responsible only for opening the file and noticing errors.
As a logical consequence of this, is_bundle() helper function can be
implemented as a non-complaining variant of read_bundle_header() that
does not return an open file descriptor, and can be used to tighten
the check used to decide the use of bundle transport in transport_get()
function.

We wished that "git bundle" to eventually learn to read from a network
socket which is not seekable. The current code opens with fopen(), reads
the file halfway and run ftell(), and reopens the same file with open()
and seeks, to skip the header.
This patch by itself does not reach that goal yet, but I think it is a
right step in that direction.

You can't currently run git-pull or git-rebase from outside
of the work tree, even with GIT_WORK_TREE set, due to an
overeager require_work_tree function. Commit e2eb527
documents this problem and provides the infrastructure for a
fix, but left it to later commits to audit and update
individual scripts.
Changing these scripts to use require_work_tree_exists is
easy to verify. We immediately call cd_to_toplevel, anyway.
Therefore no matter which function we use, the state
afterwards is one of:
1. We have a work tree, and we are at the top level.
2. We don't have a work tree, and we have died.
The only catch is that we must also make sure no code that
ran before the cd_to_toplevel assumed that we were already
in the working tree.
In this case, we will only have included shell libraries and
called set_reflog_action, neither of which care about the
current working directory at all.

The submodule merge search is not useful during virtual merges because
the results cannot be used automatically. Furthermore any suggestions
made by the search may apply to commits different than HEAD:sub and
MERGE_HEAD:sub, thus confusing the user. Skip searching for submodule
merges during a virtual merge such as that between B and C while merging
the heads of:
B---BC
/ \ /
A X
\ / \
C---CB
Run the search only when the recursion level is zero (!o->call_depth).

Since commit 68d03e4a (Implement automatic fast-forward merge for
submodules, 2010-07-07) we try to suggest submodule commits that resolve
a conflict. Consider a true recursive merge case
b---bc
/ \ /
o X
\ / \
c---cb
in which the two heads themselves (bc,cb) had resolved a submodule
conflict (i.e. reference different commits than their parents). The
submodule merge search runs during the temporary merge of the two merge
bases (b,c) and prints out a suggestion that is not meaningful to the
user. Then during the main merge the submodule merge search runs again
but dies with the message
fatal: --ancestry-path given but there are no bottom commits
while trying to enumerate candidates. Demonstrate this known breakage
with a new test in t7405-submodule-merge covering the case.

Implemented internally instead of as "git merge --no-commit && git commit"
so that "merge --edit" is otherwise consistent (hooks, etc) with "merge".
Note: the edit message does not include the status information that one
gets with "commit --status" and it is cleaned up after editing like one
gets with "commit --cleanup=default". A later patch could add the status
information if desired.
Note: previously we were not calling stripspace() after running the
prepare-commit-msg hook. Now we are, stripping comments and
leading/trailing whitespace lines if --edit is given, otherwise only
stripping leading/trailing whitespace lines if not given --edit.

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.

We should be able to ask for a config value both by its
canonical all-lowercase name (as git does internally), as
well as by random mixed-case (which will be canonicalized by
git-config for us).
Subsections are a tricky point, though. Since we have both
[section "Foo"]
and
[section.Foo]
you might want git-config to canonicalize the subsection or
not, depending on which you are expecting. But there's no
way to communicate this; git-config sees only the key, and
doesn't know which type of section name will be in the
config file.
So it must leave the subsection intact, and it is up to the
caller to provide a canonical version of the subsection if
they want to match the latter form.

The commit message for c976d41 (git-branch: add options and tests for
branch renaming, 2006-11-28) mentions RENAME_REF but otherwise this is not
documented anywhere, and it does not appear in any of the tests.
Worse yet, the name of the actual file is "RENAMED-REF".
This was supposed to hold the commit object name at the tip of the branch
the most recent "branch -m/-M" renamed, but that is not necessary in order
to be able to recover from a mistake. Even when "branch -M A B" overwrites
an existing branch B, what is kept in RENAMED-REF is the commit at the tip
of the original branch A, not the commit B from the now-lost branch.
Just remove this unused "feature".

The logic to check whether a file is a gitfile used the heuristics that
a gitfile cannot be larger than PATH_MAX or smaller than 10 bytes (as
its contents is "gitdir: " followed by a path) and returned early.
But it returned with a wrong value. It should have said "this cannot
possibly be a gitfile" by returning 0, but it returned 1 instead. Our
test cases do not cover this, as the bundle files produced are smaller
than PATH_MAX, except on Windows.
While at it, fix the faulty logic that the path stored in a gitfile cannot
be larger than PATH_MAX-sizeof("gitdir: ").

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.

Add the option -W/--function-context to git diff. It is similar to
the same option of git grep and expands the context of change hunks
so that the whole surrounding function is shown. This "natural"
context can allow changes to be understood better.
Note: GNU patch doesn't like diffs generated with the new option;
it seems to expect context lines to be the same before and after
changes. git apply doesn't complain.
This implementation has the same shortcoming as the one in grep,
namely that there is no way to explicitly find the end of a
function. That means that a few lines of extra context are shown,
right up to the next recognized function begins. It's already
useful in its current form, though.
The function get_func_line() in xdiff/xemit.c is extended to work
forward as well as backward to find post-context as well as
pre-context. It returns the position of the first found matching
line. The func_line parameter is made optional, as we don't need
it for -W.
The enhanced function is then used in xdl_emit_diff() to extend
the context as needed. If the added context overlaps with the
next change, it is merged into the current hunk.

The variable "refs" is allocated on the stack but is not initialized. It
is passed to read_packed_refs(), and its struct members may eventually be
passed to add_ref() and ALLOC_GROW(). Since the structure has not been
initialized, its members may contain random non-zero values. So let's
initialize it.
The call sequence looks something like this:
resolve_gitlink_packed_ref(...) {
struct cached_refs refs;
...
read_packed_refs(f, &refs);
...
}
read_packed_refs(FILE*, struct cached_refs *cached_refs) {
...
add_ref(name, sha1, flag, &cached_refs->packed, &last);
...
}
add_ref(..., struct ref_array *refs, struct ref_entry **) {
...
ALLOC_GROW(refs->refs, refs->nr + 1, refs->alloc);
}
