Since local branch, tags and remote tracking branch namespaces are
most often used, add shortcut notations for globbing those in
manner similar to --glob option.
With this, one can express the "what I have but origin doesn't?"
as:
'git log --branches --not --remotes=origin'

This teaches @{upstream} syntax to interpret_branch_name(), instead
of dwim_ref() machinery.
There are places in git UI that behaves differently when you give a local
branch name and when you give an extended SHA-1 expression that evaluates
to the commit object name at the tip of the branch. The intent is that
the special syntax such as @{-1} can stand in as if the user spelled the
name of the branch in such places.
The name of the branch "frotz" to switch to ("git checkout frotz"), and
the name of the branch "nitfol" to fork a new branch "frotz" from ("git
checkout -b frotz nitfol"), are examples of such places. These places
take only the name of the branch (e.g. "frotz"), and they are supposed to
act differently to an equivalent refname (e.g. "refs/heads/frotz"), so
hooking the @{upstream} and @{-N} syntax to dwim_ref() is insufficient
when we want to deal with cases a local branch is forked from another
local branch and use "forked@{upstream}" to name the forkee branch.
The "upstream" syntax "forked@{u}" is to specify the ref that "forked" is
configured to merge with, and most often the forkee is a remote tracking
branch, not a local branch. We cannot simply return a local branch name,
but that does not necessarily mean we have to returns the full refname
(e.g. refs/remotes/origin/frotz, when returning origin/frotz is enough).
This update calls shorten_unambiguous_ref() to do so.
This adds a few more tests that exercises @{upstream} syntax by commands
that operate differently when they are given branch name as opposed to a
refname (i.e. where "master" and "refs/heads/master" makes a difference).
Fix "checkout A..." synonym for "checkout A...HEAD" on Windows
When switching to a different commit, we first see the named rev exists
as a commit using lookup_commit_reference_gently(), and set new.path to
a string "refs/heads/" followed by the name the user gave us (but after
taking into special short-hands like @{-1} == "previous branch" and
"@{upstream}" == "the branch we merge with" into account). If the
resulting string names an existsing ref, then we are switching to that
branch (and will be building new commits on top of it); otherwise we are
detaching HEAD at that commit.
When the "master..." syntax is used as a short-hand for "master...HEAD",
we do want to detach HEAD at the merge base. However, on Windows, when
asked if ".git/refs/heads/master..." exists, the filesystem happily says
"it does" when ".git/refs/heads/master" exists.
Work this issue around by first calling check_ref_format(new.path) to see
if the string can possibly be a valid ref under "refs/heads/", before
asking resolve_ref().
We used to run another lookup_commit_reference(rev) even though we know it
succeeded and we have a good commit in new.commit already; this has been
with us from 782c2d6 (Build in checkout, 2008-02-07), the first version we
had "git checkout" implemented in C. Drop it.
status: don't require the repository to be writable
We need to update the index before hooks run when actually making a
commit, but we shouldn't have to write the index when running "status".
If we can, then we have already spent cycles to refresh the index and
it is a waste not to write it out, but it is not a disaster if we cannot
write it out. The main reason the user is running "git status" is to get
the "status", and refreshing the index is a mere side effect that we can
do without.
Makefile: honor NO_CURL when setting REMOTE_CURL_* variables
Previously, these variables were set before there was a chance to set
NO_CURL.
This made a difference only during 'make install', because by installing
$(REMOTE_CURL_ALIASES), the rule tries to access $(REMOTE_CURL_PRIMARY),
which was never installed. On Windows, this fails; on Unix, stale symbolic
links are created.

Performance optimization for detection of modified submodules
In the worst case is_submodule_modified() got called three times for
each submodule. The information we got from scanning the whole
submodule tree the first time can be reused instead.
New parameters have been added to diff_change() and diff_addremove(),
the information is stored in a new member of struct diff_filespec. Its
value is then reused instead of calling is_submodule_modified() again.
When no explicit "-dirty" is needed in the output the call to
is_submodule_modified() is not necessary when the submodules HEAD
already disagrees with the ref of the superproject, as this alone
marks it as modified. To achieve that, get_stat_data() got an extra

Make "subtree" part more orthogonal to the rest of merge-recursive.
This makes "subtree" more orthogonal to the rest of recursive merge, so
that you can use subtree and ours/theirs features at the same time. For
example, you can now say:
git merge -s subtree -Xtheirs other
to merge with "other" branch while shifting it up or down to match the
shape of the tree of the current branch, and resolving conflicts favoring
the changes "other" branch made over changes made in the current branch.
It also allows the prefix used to shift the trees to be specified using
the "-Xsubtree=$prefix" option. Giving an empty prefix tells the command
to figure out how much to shift trees automatically as we have always
done. "merge -s subtree" is the same as "merge -s recursive -Xsubtree="
(or "merge -s recursive -Xsubtree").

MSVC: Fix an "incompatible pointer types" compiler warning
In particular, the following warning is issued while compiling
compat/msvc.c:
...mingw.c(223) : warning C4133: 'function' : incompatible \
types - from '_stati64 *' to '_stat64 *'
which relates to a call of _fstati64() in the mingw_fstat()
function definition.
This is caused by various layers of macro magic and attempts to
avoid macro redefinition compiler warnings. For example, the call
to _fstati64() mentioned above is actually a call to _fstat64(),
and expects a pointer to a struct _stat64 rather than the struct
_stati64 which is passed to mingw_fstat().
The definition of struct _stati64 given in compat/msvc.h had the
same "shape" as the definition of struct _stat64, so the call to
_fstat64() does not actually cause any runtime errors, but the
structure types are indeed incompatible.
In order to avoid the compiler warning, we add declarations for the
mingw_lstat() and mingw_fstat() functions and supporting macros to
msvc.h, suppressing the corresponding declarations in mingw.h, so
that we can use the appropriate structure type (and function) names
from the msvc headers.

Windows: avoid the "dup dance" when spawning a child process
When stdin, stdout, or stderr must be redirected for a child process that
on Windows is spawned using one of the spawn() functions of Microsoft's
C runtime, then there is no choice other than to
1. make a backup copy of fd 0,1,2 with dup
2. dup2 the redirection source fd into 0,1,2
3. spawn
4. dup2 the backup back into 0,1,2
5. close the backup copy and the redirection source
We used this idiom as well -- but we are not using the spawn() functions
anymore!
Instead, we have our own implementation. We had hardcoded that stdin,
stdout, and stderr of the child process were inherited from the parent's
fds 0, 1, and 2. But we can actually specify any fd.
With this patch, the fds to inherit are passed from start_command()'s
WIN32 section to our spawn implementation. This way, we can avoid the
backup copies of the fds.
The backup copies were a bug waiting to surface: The OS handles underlying
the dup()ed fds were inherited by the child process (but were not
associated with a file descriptor in the child). Consequently, the file or
pipe represented by the OS handle remained open even after the backup copy
was closed in the parent process until the child exited.
Since our implementation of pipe() creates non-inheritable OS handles, we
still dup() file descriptors in start_command() because dup() happens to
create inheritable duplicates. (A nice side effect is that the fd cleanup
in start_command is the same for Windows and Unix and remains unchanged.)
Signed-off-by: Johannes Sixt <j6t@kdbg.org> Signed-off-by: Junio C Hamano <gitster@pobox.com>
Our implementation of pipe() must create non-inheritable handles for the
reason that when a child process is started, there is no opportunity to
close the unneeded pipe ends in the child (on POSIX this is done between
fork() and exec()).
Previously, we used the _pipe() function provided by Microsoft's C runtime
(which creates inheritable handles) and then turned the handles into
non-inheritable handles using the DuplicateHandle() API.
Simplify the procedure by using the CreatePipe() API, which can create
non-inheritable handles right from the beginning.
