Allow a safer "rewind of the remote tip" push than blind "--force",
by requiring that the overwritten remote ref to be unchanged since
the new history to replace it was prepared.
The machinery is more or less ready. The "--force" option is again
the big red button to override any safety, thanks to J6t's sanity
(the original round allowed --lockref to defeat --force).
The logic to choose the default implemented here is fragile
(e.g. "git fetch" after seeing a failure will update the
remote-tracking branch and will make the next "push" pass,
defeating the safety pretty easily). It is suitable only for the
simplest workflows, and it may hurt users more than it helps them.

Allow fetch.prune and remote.*.prune configuration variables to be set,
and "git fetch" to behave as if "--prune" is given.
"git fetch" that honors remote.*.prune is fine, but I wonder if we
should somehow make "git push" aware of it as well. Perhaps
remote.*.prune should not be just a boolean, but a 4-way "none",
"push", "fetch", "both"?

The recent "short-cut clone connectivity check" topic broke a
shallow repository when a fetch operation tries to auto-follow tags.
* nd/fetch-pack-shallow-fix:
fetch-pack: do not remove .git/shallow file when --depth is not specified
|
|
fetch_pack() can remove .git/shallow file when a shallow repository
becomes a full one again. This behavior is triggered incorrectly when
tags are also fetched because fetch_pack() will be called twice. At
the first fetch_pack() call:
- shallow_lock is set up
- alternate_shallow_file points to shallow_lock.filename, which is
"shallow.lock"
- commit_lock_file is called, which sets shallow_lock.filename to "".
alternate_shallow_file also becomes "" because it points to the
same memory.
At the second call, setup_alternate_shallow() is not called and
alternate_shallow_file remains "". It's mistaken as unshallow case and
.git/shallow is removed. The end result is a broken repository.
Fix this by always initializing alternate_shallow_file when
fetch_pack() is called. As an extra measure, check if args->depth > 0
before commit/rollback shallow file.

Old Bash (3.0) which is distributed with RHEL 4.X and other ancient
platforms that are still in wide use, does not understand the
array+=() notation. Let's use an explicit assignment to the new array
element which works everywhere, like:
array[${#array[@]}+1]=''
The right-hand side '' is not strictly necessary, but in this case
I think it is more clear.

Git fails due to a segmentation fault if a submodule path is empty.
Here is an example .gitmodules that will cause a segmentation fault:
[submodule "foo-module"]
path
url = http://host/repo.git
$ git status
Segmentation fault (core dumped)
This is because the parsing of "submodule.*.path" is not prepared to
see a value-less "true" and assumes that the value is always
non-NULL (parsing of "ignore" has the same problem).
Fix it by checking the NULL-ness of value and complain with
config_error_nonbool().

Newlines in the path to a git repository were not an issue for the
git-specific bash prompt before commit efaa0c1532 (bash prompt:
combine 'git rev-parse' executions in the main code path, 2013-06-17),
because the path returned by 'git rev-parse --git-dir' was directly
stored in a variable, and this variable was later always accessed
inside double quotes.
Newlines are not an issue after commit efaa0c1532 either, but it's
more subtle. Since efaa0c1532 we use the following single 'git
rev-parse' execution to query various info about the repository:
git rev-parse --git-dir --is-inside-git-dir \
--is-bare-repository --is-inside-work-tree
The results to these queries are separated by a newline character in
the output, e.g.:
/home/szeder/src/git/.git
false
false
true
A newline in the path to the git repository could potentially break
the parsing of these results and ultimately the bash prompt, unless
the parsing is done right. Commit efaa0c1532 got it right, as I
consciously started parsing 'git rev-parse's output from the end,
where each record is a single line containing either 'true' or 'false'
or, after e3e0b9378b (bash prompt: combine 'git rev-parse' for
detached head, 2013-06-24), the abbreviated commit object name, and
all what remains at the beginning is the path to the git repository,
no matter how many lines it is.
This subtlety really warrants its own test, especially since I didn't
explain it in the log message or in an in-code comment back then, so
add a test to excercise the prompt with newline characters in the path
to the repository. Guard this test with the FUNNYNAMES prerequisite,
because not all filesystems support newlines in filenames. Note that
'git rev-parse --git-dir' prints '.git' or '.' when at the top of the
worktree or the repository, respectively, and only prints the full
path to the repository when in a subdirectory, hence the need for
changing into a subdir in the test.

This reverts commit cdfd94837b27c220f70f032b596ea993d195488f, as it
does not just apply to "@" (and forms with modifiers like @{u}
applied to it), but also affects e.g. "refs/heads/@/foo", which it
shouldn't.
The basic idea of giving a short-hand might be good, and the topic
can be retried later, but let's revert to avoid affecting existing
use cases for now for the upcoming release.

This reverts commit a73653130edd6a8977106d45a8092c09040f9132, as it
has been reported that "ls-files --killed" is too time-consuming in
a deep directory with too many untracked crufts (e.g. $HOME/.git
tracking only a few files).
We'd need to revisit it later but "ls-files --killed" needs to be
optimized before it happens.

* jk/submodule-subdirectory-ok:
t/t7407: fix two typos in submodule tests
|
|
In t/t7407-submodule-foreach.sh there is a typo in one of the
path names given for a test step. The correct path is
nested1/nested2/.git, but nested1/nested1/nested2/.git is
given instead. The typo is hidden because this line also
accidentally omits the && chain operator. The omitted chain
also means the return values of all the previous commands in
this test are also being ignored.
Fix the path and add the chain operator so the entire test
sequence can be properly validated.

Some implementations of 'echo' (e.g. dash's built-in) interpret
backslash sequences in their arguments.
This triggered at least one bug: the error message of "rebase -i" was
turning \t in commit messages into actual tabulations. There may be
others.
Using "printf '%s\n'" instead avoids this bad behavior, and is the form
used by the "say" function.

58960978 and 99780b0a added tests which demonstrated bugs (crashes) in
range-set and line-log when handed empty ranges specified via "log
-LX:file" where X is one greater than the last line of the file. After
these tests were added, it was realized that the ability to specify an
empty range is a loophole due to a bug in -L bounds checking. That bug
is slated to be fixed in a subsequent patch.
Unfortunately, the closure of this loophole makes it impossible to
continue checking range-set and line-log behavior with regard to empty
ranges since there is no other way to specify empty ranges via the
command-line. APIs of both facilities are private (file static) so
there likewise is no way to test their behaviors programmatically.
Consequently, retire these two tests.

Since inception, -LX,Y has correctly reported an out-of-range error when
Y is beyond end of file, however, X was not checked, and an out-of-range
X would cause a crash. 92f9e273 (blame: prevent a segv when -L given
start > EOF; 2010-02-08) attempted to rectify this shortcoming but has
its own off-by-one error which allows X to extend one line past end of
file. For example, given a file with 5 lines:
git blame -L5 foo # OK, blames line 5
git blame -L6 foo # accepted, no error, no output, huh?
git blame -L7 foo # error "fatal: file foo has only 5 lines"
Fix this bug.
In order to avoid regressing "blame foo" when foo is an empty file, the
fix is slightly more complicated than changing '<' to '<='.

Add boundary case tests, with and without -L, for empty file; file with
one partial line; file with one full line.
The empty file test without -L is of particular interest. Historically,
this case has been supported (empty blame output) and this test protects
against regression by a subsequent patch fixing an off-by-one bug which
incorrectly accepts -LX where X is one past end-of-file.

t8001, t8002: fix "blame -L :literal" test on NetBSD

Sub-test 42 of t8001 and t8002 ("blame -L :literal") fails on NetBSD
with the following verbose output:
git annotate -L:main hello.c
Author F (expected 4, attributed 3) bad

This is not caused by different behaviour of git blame or annotate on
that platform, but by different test input, in turn caused by a sed
command that forgets to add a newline on NetBSD. Here's the diff of the
commit that adds "goodbye" to hello.c, for Linux:

It is not like that our longer term desire is to someday start
accept log messages with NULs in them, so it is wrong to mark a test

The test file that the UTF-16 rejection test looks for is missing, but this went
unnoticed because the test is expected to fail anyway; as a consequence, the

because the test file contains a NUL byte. Fix this by including a sample text
file containing a commit message encoded in UTF-16.

Commit c334b87b (cat-file: split --batch input lines on whitespace,
2013-07-11) taught `cat-file --batch-check` to split input lines on
the first whitespace, and stash everything after the first token
into the %(rest) output format element. It claimed:
Object names cannot contain spaces, so any input with
spaces would have resulted in a "missing" line.
But that is not correct. Refs, object sha1s, and various peeling
suffixes cannot contain spaces, but some object names can. In
particular:
1. Tree paths like "[<tree>]:path with whitespace"
2. Reflog specifications like "@{2 days ago}"
3. Commit searches like "rev^{/grep me}" or ":/grep me"
To remain backwards compatible, we cannot split on whitespace by
default, hence we will ship 1.8.4 with the commit reverted.
Resurrect its attempt but in a weaker form; only do the splitting
when "%(rest)" is used in the output format. Since that element did
not exist at all before c334b87, old scripts cannot be affected.
The existence of object names with spaces does mean that you
cannot reliably do:
echo ":path with space and other data" |
git cat-file --batch-check="%(objectname) %(rest)"
as it would split the path and feed only ":path" to get_sha1. But
that command is nonsensical. If you wanted to see "and other data"
in "%(rest)", git cannot possibly know where the filename ends and
the "rest" begins.
It might be more robust to have something like "-z" to separate the
input elements. But this patch is still a reasonable step before
having that. It makes the easy cases easy; people who do not care
about %(rest) do not have to consider it, and the %(rest) code
handles the spaces and newlines of "rev-list --objects" correctly.
Hard cases remain hard but possible (if you might get whitespace in
your input, you do not get to use %(rest) and must split and join
the output yourself using more flexible tools). And most
importantly, it does not preclude us from having different splitting
rules later if a "-z" (or similar) option is added. So we can make
the hard cases easier later, if we choose to.

HTTP servers may send Set-Cookie headers in a response and expect them
to be set on subsequent requests. By default, libcurl behavior is to
store such cookies in memory and reuse them across requests within a
single session. However, it may also make sense, depending on the
server and the cookies, to store them across sessions. Provide users
an option to enable this behavior, writing cookies out to the same
file specified in http.cookiefile.

`echo -n` is non-portable. The POSIX specification says:
Conforming applications that wish to do prompting without <newline>

use the printf utility derived from the Ninth Edition system.

replace `echo -n` invocations with printf.
