d748765ea6 Unbreak interactive GPG prompt upon signing
With the recent update in efee955 (gpg-interface: check gpg signature
creation status, 2016-06-17), we ask GPG to send all status updates to
stderr, and then catch the stderr in an strbuf.

But GPG might fail, and send error messages to stderr. And we simply
do not show them to the user.

Even worse: this swallows any interactive prompt for a passphrase. And
detaches stderr from the tty so that the passphrase cannot be read.

So while the first problem could be fixed (by printing the captured
stderr upon error), the second problem cannot be easily fixed, and
presents a major regression.

So let's just revert commit efee9553a4.

This fixes https://github.com/git-for-windows/git/issues/871

317b96b0c1 version --build-options: report commit, too, if possible
In particular when local tags are used (or tags that are pushed to some
fork) to build Git, it is very hard to figure out from which particular
revision a particular Git executable was built.

Let's just report that in our build options.

We need to be careful, though, to report when the current commit cannot be
determined, e.g. when building from a tarball without any associated Git
repository.

666a9c0ad6 mingw: respect core.hidedotfiles = false in git-init again
This is a brown paper bag. When adding the tests, we actually failed
to verify that the config variable is heeded in git-init at all. And
when changing the original patch that marked the .git/ directory as
hidden after reading the config, it was lost on this developer that
the new code would use the hide_dotfiles variable before the config
was read.

The fix is obvious: read the (limited, pre-init) config *before*
creating the .git/ directory.

8a61a6d452 Preliminary support for reporting build platform
Add preliminary support for detection of the build plaform, and reporting
of same with the `git version --build-options' command. This can be useful
for bug reporting, to distinguish between 32 and 64-bit builds for
example.

The current implementation can only distinguish between x86 and x86_64.
This will be extended in future patches. In addition, all 32-bit variants
(i686, i586, etc.) are collapsed into `x86'. An example of the output is:

   $ git version --build-options
   git version 2.9.3.windows.2.826.g06c0f2f
   sizeof-long: 4
   machine: x86_64

The label of `machine' was chosen so the new information will approximate
the output of `uname -m'.

35d4646cf9 status: offer *not* to lock the index and update it
When a third-party tool periodically runs `git status` in order to keep
track of the state of the working tree, it is a bad idea to lock the
index: it might interfere with interactive commands executed by the
user, e.g. when the user wants to commit files.

Let's introduce the option `--no-lock-index` to prevent such problems.
The idea is that the third-party tool calls `git status` with this
option, preventing it from ever updating the index.

The downside is that the periodic `git status` calls will be a little
bit more wasteful because they may have to refresh the index repeatedly,
only to throw away the updates when it exits. This cannot really be
helped, though, as tools wanting to get a periodic update of the status
have no way to predict when the user may want to lock the index herself.

Note that the regression test added in this commit does not *really*
verify that no index.lock file was written; that test is not possible in
a portable way. Instead, we verify that .git/index is rewritten *only*
when `git status` is run without `--no-lock-index`.

ebca6ba688 bundle: refuse to create empty bundle

<bundle> <revlist>` where <revlist> resolves to an empty list (for
example, like `master..master`), the command fails and warns the user

e93acec8f6 gc/repack: release packs when needed
On Windows, files cannot be removed nor renamed if there are still
handles held by a process. To remedy that, we introduced the
close_all_packs() function.

Earlier, we made sure that the packs are released just before `git gc`
is spawned, in case that gc wants to remove no-longer needed packs.

But this developer forgot that gc itself also needs to let go of packs,
e.g. when consolidating all packs via the --aggressive option.

Likewise, `git repack -d` wants to delete obsolete packs and therefore
needs to close all pack handles, too.

a53306c284 mingw: support spawning programs containing spaces in their names
The CreateProcessW() function does not really support spaces in its
first argument, lpApplicationName. But it supports passing NULL as
lpApplicationName, which makes it figure out the application from the
(possibly quoted) first argument of lpCommandLine.

Let's use that trick (if we are certain that the first argument matches
the executable's path) to support launching programs whose path contains
spaces.

7fc9ac2065 Do not mask the username when reading credentials
When user is asked for credentials there is no need to mask username,
so PROMPT_ASKPASS flag on calling credential_ask_one for login is
unnecessary.

credential_ask_one internally uses git_prompt which in case of given
flag PROMPT_ASKPASS uses masked input method instead of
git_terminal_prompt, which does not mask user input.

ff0c2c3649 git gui: fix staging a second line to a 1-line file
When a 1-line file is augmented by a second line, and the user tries to
stage that single line via the "Stage Line" context menu item, we do not
want to see "apply: corrupt patch at line 5".

The reason for this error was that the hunk header looks like this:

	@@ -1 +1,2 @@

but the existing code expects the original range always to contain a
comma. This problem is easily fixed by cutting the string "1 +1,2"
(that Git GUI formerly mistook for the starting line) at the space.

7b4cbb3fa6 Enable DEP and ASLR
Enable DEP (Data Execution Prevention) and ASLR (Address Space Layout
Randomization) support. This applies to both 32bit and 64bit builds
and makes it substantially harder to exploit security holes in Git by
offering a much more unpredictable attack surface.

ASLR interferes with GDB's ability to set breakpoints. A similar issue
holds true when compiling with -O2 (in which case single-stepping is
messed up because GDB cannot map the code back to the original source
code properly). Therefore we simply enable ASLR only when an
optimization flag is present in the CFLAGS, using it as an indicator
that the developer does not want to debug in GDB anyway.

Commit 4b623d8 (MSVC: link in invalidcontinue.obj for better
POSIX compatibility, 2014-03-29) introduced invalidcontinue.obj

there is no matching source file.

Only substitute filenames ending with .o when generating the
source .c filename, otherwise a .cbj file may be expected.

Split the .o and .obj processing; 'make' does not produce .obj
files.

In the future there may be source files that produce .obj files
so keep the two issues (.obj files with & without source files)
separate.
