git-prompt.sh: don't assume the shell expands the value of PS1
Not all shells subject the prompt string to parameter expansion. Test
whether the shell will expand the value of PS1, and use the result to
control whether raw ref names are included directly in PS1.
This fixes a regression introduced in commit 8976500 ("git-prompt.sh:
don't put unsanitized branch names in $PS1"): zsh does not expand PS1
by default, but that commit assumed it did. The bug resulted in
prompts containing the literal string '${__git_ps1_branch_name}'
instead of the actual branch name.

rebase -i: handle "Nothing to do" case with autostash
When a user invokes
$ git rebase -i @~3
with dirty files and rebase.autostash turned on, and exits the $EDITOR
with an empty buffer, the autostash fails to apply. Although the primary
focus of rr/rebase-autostash was to get the git-rebase--backend.sh
scripts to return control to git-rebase.sh, it missed this case in
git-rebase--interactive.sh. Since this case is unlike the other cases
which return control for housekeeping, assign it a special return status
and handle that return value explicitly in git-rebase.sh.

commit: allow core.commentChar=auto for character auto selection
When core.commentChar is "auto", the comment char starts with '#' as
in default but if it's already in the prepared message, find another
char in a small subset. This should stop surprises because git strips
some lines unexpectedly.
Note that git is not smart enough to recognize '#' as the comment char
in custom templates and convert it if the final comment char is
different. It thinks '#' lines in custom templates as part of the
commit message. So don't use this with custom templates.

git-gui: tolerate major version changes when comparing the git version
Since git 2.0.0 starting git gui in a submodule using a gitfile fails with
the following error:
No working directory ../../../<path>
couldn't change working directory
to "../../../<path>": no such file or
directory
This is because "git rev-parse --show-toplevel" is only run when git gui
sees a git version of at least 1.7.0 (which is the version in which the
--show-toplevel option was introduced). But "package vsatisfies" returns
false when the major version changes, which is not what we want here.
Fix that for both places where the git version is checked using vsatisfies
by appending a '-' to the version number. This tells vsatisfies that a
change of the major version is not considered to be a problem, as long as
the new major version is larger. This is done for both the place that
caused the reported bug and another spot where the git version is tested
for another feature.

git grep -O -i: if the pager is 'less', pass the '-I' option
When <command> happens to be the magic string "less", today
git grep -O<command> -e<pattern>
helpfully passes +/<pattern> to less so you can navigate through
the results within a file using the n and shift+n keystrokes.
Alas, that doesn't do the right thing for a case-insensitive match,
i.e.
git grep -i -O<command> -e<pattern>
For that case we should pass --IGNORE-CASE to "less" so that n and
shift+n can move between results ignoring case in the pattern.
The original patch came from msysgit and used "-i", but that was not
due to lack of support for "-I" but it merely overlooked that it
ought to work even when the pattern contains capital letters.

When we try to open a loose object file, we first attempt to
open in the local object database, and then try any
alternates. This means that the errno value when we return
will be from the last place we looked (and due to the way
the code is structured, simply ENOENT if we do not have have
any alternates).
This can cause confusing error messages, as read_sha1_file
checks for ENOENT when reporting a missing object. If errno
is something else, we report that. If it is ENOENT, but
has_loose_object reports that we have it, then we claim the
object is corrupted. For example:
This patch instead keeps track of the "most interesting"
errno we receive during our search. We consider ENOENT to be
the least interesting of all, and otherwise report the first
error found (so problems in the object database take
precedence over ones in alternates). Here it is with this
patch:
The argv_array_detach function (and associated free() function) was

This simplifies the code and avoids a fixed array size that

The get_helper functions dynamically allocates an
argv_array, feeds it to start_command, and then returns. We
then have to later clean up the memory manually after
calling finish_command. We can make this simpler by just
using run-command's internal argv_array, which handles
cleanup for us.
This also prevents a memory leak in the case that
transport_take_over is used, in which case we free the child
in finish_connect, which does not manually free the array.
Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
This avoids magic numbers when we allocate fixed-size argv
arrays, and makes it more obvious that we are not
overflowing.
It is also the first step to fixing a memory leak. When
git_connect returns a child_process struct, the argv array
in the struct is dynamically allocated, but the individual
strings are not (they are either owned elsewhere, or are
freed). Later, in finish_connect, we free the array but
leave the strings alone.
This works for the child_process created by git_connect, but
if we use transport_take_over, we may also end up with a
child_process created by transport-helper's get_helper.
In that case, the strings are freshly allocated, and we
would want to free them. However, we have no idea in
finish_connect which type we have.
By consistently using run-command's internal argv-array, we
do not have to worry about this issue at all; finish_command
takes care of it for us, and we can drop our manual free
entirely.
Note that this actually makes the get_helper leak slightly
worse; now we are leaking both the strings and the array.
But when we adjust it in a future patch, that leak will go
away entirely.

We currently set up the argv array by hand in a fixed-size
stack-local array. Using an argv array is more readable, as
it handles buffer allocation us (not to mention makes it
obvious we do not overflow the array).
However, there's a more subtle benefit, too. We leave the
function having run start_command (with the child_process
in a static global), and then later run finish_command from
another function. That means when we run finish_command,
neither column_process.argv nor the memory it points to is
valid any longer.
Most of the time finish_command does not bother looking at
argv, but it may if it encounters an error (e.g., waitpid
failure or signal death). This is unusual, which is why
nobody has noticed. But by using run-command's built-in
argv_array, the memory ownership is handled for us
automatically.
Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
All child_process structs need to point to an argv. For
flexibility, we do not mandate the use of a dynamic
argv_array. However, because the child_process does not own
the memory, this can make memory management with a
separate argv_array difficult.
For example, if a function calls start_command but not
finish_command, the argv memory must persist. The code needs
to arrange to clean up the argv_array separately after
finish_command runs. As a result, some of our code in this
situation just leaks the memory.
To help such cases, this patch adds a built-in argv_array to
the child_process, which gets cleaned up automatically (both
in finish_command and when start_command fails). Callers
may use it if they choose, but can continue to use the raw
argv if they wish.

run_diff_files: do not look at uninitialized stat data
If we try to diff an index entry marked CE_VALID (because it
was marked with --assume-unchanged), we do not bother even
running stat() on the file to see if it was removed. This
started long ago with 540e694 (Prevent diff machinery from
examining assume-unchanged entries on worktree, 2009-08-11).
However, the subsequent code may look at our "struct stat"
and expect to find actual data; currently it will find
whatever cruft was left on the stack. This can cause
problems in two situations:
1. We call match_stat_with_submodule with the stat data,
so a submodule may be erroneously marked as changed.
2. If --find-copies-harder is in effect, we pass all
entries, even unchanged ones, to diff_change, so it can
list them as rename/copy sources. Since we found no
change, we assume that function will realize it and not
actually display any diff output. However, we end up
feeding it a bogus mode, leading it to sometimes claim
there was a mode change.
We can fix both by splitting the CE_VALID and regular code
paths, and making sure only to look at the stat information
in the latter. Furthermore, we push the declaration of our
"struct stat" down into the code paths that actually set it,
so we cannot accidentally access it uninitialized in future
code.

git-show: fix 'git show -s' to not add extra terminator after merge commit
When git show -s is called for merge commit it prints extra newline
after any merge commit. This differs from output for commits with one
parent. Fix it by more thorough checking that diff output is disabled.
The code in question exists since commit 3969cf7db1. The additional
newline is really needed for cases when patch is requested, test
t4013-diff-various.sh contains cases which can demonstrate behavior when
the condition is restricted further.
Tests:
Added merge commit to 'set up a bit of history' case in t7007-show.sh to
cover the fix.
Existing tests are updated to demonstrate the new behaviour. Earlier,
the tests that used "git show -s --pretty=format:%s", even though
"--pretty=format:%s" calls for item separator semantics and does not ask
for the terminating newline after the last item, expected the output to
end with such a newline. They were relying on the buggy behaviour. Use
of "--format=%s", which is equivalent to "--pretty=tformat:%s" that asks
for a terminating newline after each item, is a more realistic way to
use the command.
In the test 'merge log messages' the expected data is changed, because
it was explicitly listing the extra newline. Also the msg.nologff and
msg.nolognoff expected files are replaced by one msg.nolog, because they
were diffing because of the bug, and now there should be no difference.

By default, Git used to set $LESS to -FRSX if $LESS was not set by
the user. The FRX flags actually make sense for Git (F and X because
sometimes the output Git pipes to less is short, and R because Git
pipes colored output). The S flag (chop long lines), on the other
hand, is not related to Git and is a matter of user preference. Git
should not decide for the user to change LESS's default.
More specifically, the S flag harms users who review untrusted code
within a pager, since a patch looking like:
-old code;
+new good code; [... lots of tabs ...] malicious code;
would appear identical to:
-old code;
+new good code;
Users who prefer the old behavior can still set the $LESS environment
variable to -FRSX explicitly, or set core.pager to 'less -S'.
The documentation in config.txt is made a bit longer to keep both an
example setting the 'S' flag (needed to recover the old behavior)

contrib/subtree/Makefile: clean up rules to generate documentation
git:Documentation/Makefile establishes asciidoc/xmlto calls as being
handled through their appropriate variables, Hence, change to bring into

Similarly, MANPAGE_XSL exists in git:Documentation/Makefile, while
MANPAGE_NORMAL_XSL does not outside contrib/subtree. Hence, replace
MANPAGE_NORMAL_XSL with MANPAGE_XSL.

Here are some benchmarks (pu variant of git blame):

Commit e208f9c converted error() into a macro to make its
constant return value more apparent to calling code. Commit 5ded807 prevents us using this macro with clang, since
clang's -Wunused-value is smart enough to realize that the
constant "-1" is useless in some contexts.
However, since the last commit puts the constant behind an
inline function call, this is enough to prevent the
-Wunused-value warning on both modern gcc and clang. So we
can now re-enable the macro when compiling with clang.
Tested with clang 3.3, 3.4, and 3.5.

Commit e208f9c introduced a macro to turn error() calls
into:
(error(), -1)
to make the constant return value more visible to the
calling code (and thus let the compiler make better
decisions about the code).
This works well for code like:
return error(...);
but the "-1" is superfluous in code that just calls error()
without caring about the return value. In older versions of
gcc, that was fine, but gcc 4.9 complains with -Wunused-value.
We can work around this by encapsulating the constant return
value in a static inline function, as gcc specifically
avoids complaining about unused function returns unless the
function has been specifically marked with the
warn_unused_result attribute.
We also use the same trick for config_error_nonbool and
opterror, which learned the same error technique in a469a10.

Users may already store sensitive data such as imap.pass in
.git/config; making the file world-readable when "git config"
is called to edit means their password would be compromised

Dynamic linking is generally preferred over static linking, and MSVCRT.dll
has been integral part of Windows for a long time.
This also fixes linker warnings for _malloc and _free in zlib.lib, which
seems to be compiled for MSVCRT.dll already.
The DLL version also exports some of the CRT initialization functions,
which are hidden in the static libcmt.lib (e.g. __wgetmainargs, required by
subsequent Unicode patches).

Right now we pass off the string found by "--date" straight
to the fmt_ident function, which will use our strict
parse_date to normalize it. However, this means obvious
things like "--date=now" or "--date=2.days.ago" will not
work.
Instead, let's fallback to the approxidate function to
handle this for us. Note that we must try parse_date
ourselves first, even though approxidate will try strict
parsing itself. The reason is that approxidate throws away
any timezone information it sees from the strict parsing,
and we want to preserve it. So asking for:
commit: print "Date" line when the user has set date
When we make a commit and the author is not the same as the
committer (e.g., because you used "-c $commit" or
"--author=$somebody"), we print the author's name and email
in both the commit-message template and as part of the
commit summary. This is a safety check to give the user a
chance to confirm that we are doing what they expect.
This patch brings the same safety for the "date" field,
which may be set by "-c" or by using "--date". Note that we
explicitly do not set it for $GIT_AUTHOR_DATE, as it is
probably not of interest when "git commit" is being fed its
parameters by a script.
