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"?

fetch: make --prune configurable

Without "git fetch --prune", remote-tracking branches for a branch
the other side already has removed will stay forever. Some people
want to always run "git fetch --prune".
To accommodate users who want to either prune always or when fetching
from a particular remote, add two new configuration variables
"fetch.prune" and "remote.<name>.prune":
- "fetch.prune" allows to enable prune for all fetch operations.
- "remote.<name>.prune" allows to change the behaviour per remote.
The latter will naturally override the former, and the --[no-]prune
option from the command line will override the configured default.
Since --prune is a potentially destructive operation (Git doesn't
keep reflogs for deleted references yet), we don't want to prune
without users consent, so this configuration will not be on by
default.

Pass a list of open bzrlib.transport.Transport objects to each bzrlib
function that might create a transport. This enables bzrlib to reuse
existing transports when possible, avoiding multiple concurrent
connections to the same remote server.
If the remote server is accessed via ssh, this fixes a couple of
problems:
* If the user does not have keys loaded into an ssh agent, the user
may be prompted for a password multiple times.
* If the user is using OpenSSH and the ControlMaster setting is set
to auto, git-remote-bzr might hang. This is because bzrlib closes
the multiple ssh sessions in an undefined order and might try to
close the master ssh session before the other sessions. The
master ssh process will not exit until the other sessions have
exited, causing a deadlock. (The ssh sessions are closed in an
undefined order because bzrlib relies on the Python garbage
collector to trigger ssh session termination.)

Convert most uses of OPT_BOOLEAN/OPTION_BOOLEAN that can use
OPT_BOOL/OPTION_BOOLEAN which have much saner semantics, and turn

The revert command comes with their own implementation of checking
for exclusiveness of parameters.
Now that the OPT_CMDMODE is in place, we can also rely on that macro
instead of cooking that solution for each command itself.
This commit also replaces OPT_BOOLEAN, which was deprecated by b04ba2bb
(parse-options: deprecate OPT_BOOLEAN, 2011-09-27). Instead OPT_BOOL is
used.

The --no-create was parsed with OPT_BOOLEAN, which has a counting up
logic implemented. Since b04ba2bb (parse-options: deprecate OPT_BOOLEAN,
2011-09-27) the OPT_BOOLEAN is deprecated and is only a define:
/* Deprecated synonym */
#define OPTION_BOOLEAN OPTION_COUNTUP
However the variable not_new, which can be counted up by giving
--no-create multiple times, is used to set a bit in the struct checkout
bitfield (defined in cache.h:969, declared at builtin/checkout-index.c:19):
state.not_new = not_new;
When assigning a value other than 0 or 1 to a bit, all leading digits but
the last are ignored and only the last bit is used for setting the bit
variable.
Hence the following:
# in git.git:
$ git status
# working directory clean
rm COPYING
$ git status
# deleted: COPYING
$ git checkout-index -a -n
$ git status
# deleted: COPYING
# which is expected as we're telling git to not restore or create
# files, however:
$ git checkout-index -a -n -n
$ git status
# working directory clean, COPYING is restored again!
# That's the bug, we're fixing here.
By restraining the variable not_new to a value being definitely 0 or 1
by the macro OPT_BOOL the bug is fixed.

This task emerged from b04ba2bb (parse-options: deprecate OPT_BOOLEAN,
2011-09-27).
This commit introduces a change for the users, after this patch
you can pass one of the config level flags multiple times:
Before:
$ git config --global --global --list
error: only one config file at a time.
usage: ...
Afterwards this will work. This is due to the following check in the code:
if (use_global_config + use_system_config + use_local_config +
!!given_config_file + !!given_config_blob > 1) {
error("only one config file at a time.");
usage_with_options(builtin_config_usage, builtin_config_options);
}
With OPT_BOOL instead of OPT_BOOLEAN the variables use_global_config,
use_system_config, use_local_config will only have the value 0 if the
command line option was not passed or 1 no matter how often the
respective command line option was passed.

This task emerged from b04ba2bb (parse-options: deprecate OPT_BOOLEAN,
2011-09-27). hash-object is a plumbing layer command, so better
not change the input/output behavior for now.
Unfortunately we have these lines relying on the count up mechanism of
OPT_BOOLEAN:
if (hashstdin > 1)
errstr = "Multiple --stdin arguments are not supported";
Using OPT_BOOL will make "git hash-object --stdin --stdin" the same
as "git hash-object --stdin", resulting in just one object, which
will surprise users with an expectation to see two objects hashed.
Because it is not good to silently succeed and give an unexpected
result, even when the expectation is unrealistic, we use COUNTUP to
explicitly catch such an error.

Now that the variables are set by OPT_BOOL, which makes sure
to have the values being 0 or 1 after parsing, we do not need
the double negation to map any other value to 1 for integer
variables.

This patch allows users to use the short form -q on
log and format-patch, which was non possible before.
Also the documentation of format-patch mentions -q now.
The documentation of log doesn't even talk about --quiet, so I'll leave
that for more experienced git contributors. ;)
It doesn't seem to change the default behavior, but in combination
with --stat for example it suppresses the actual stats.
however the only relevant code in log is
if (quiet)
rev->diffopt.output_format |= DIFF_FORMAT_NO_OUTPUT;

This task emerged from b04ba2bb (parse-options: deprecate OPT_BOOLEAN,
2011-09-27). All occurrences of the respective variables have
been reviewed and none of them relied on the counting up mechanism,
but all of them were using the variable as a true boolean.
This patch does not change semantics of any command intentionally.

As of b04ba2bb4 OPTION_BOOLEAN was deprecated.
This commit removes all occurrences of OPTION_BOOLEAN.
In b04ba2bb4 Junio suggested to replace it with either
OPTION_SET_INT or OPTION_COUNTUP instead. However a pattern, which
occurred often with the OPTION_BOOLEAN was a hidden boolean parameter.
So I defined OPT_HIDDEN_BOOL as an additional possible parse option
in parse-options.h to make life easy.
The OPT_HIDDEN_BOOL was used in checkout, clone, commit, show-ref.
The only exception, where there was need to fiddle with OPTION_SET_INT
was log and notes. However in these two files there is also a pattern,
so we could think of introducing OPT_NONEG_BOOL.

Many commands use --dashed-option as a operation mode selector
(e.g. "git tag --delete") that the user can use at most one
(e.g. "git tag --delete --verify" is a nonsense) and you cannot
negate (e.g. "git tag --no-delete" is a nonsense). Make it easier
for users of parse_options() to enforce these restrictions.

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.

The code sequence ' (1u << i) < hsize && i < 31 ' is a multi step
process, whose first step requires that 'i' is already less that 31,
otherwise the result (1u << i) is undefined (and 'undef_val < hsize'
can therefore be assumed to be 'false'), and so the later test i < 31
can always be optimized away as dead code ('i' is already less than 31,
or the short circuit 'and' applies).
So we need to get rid of that code. One way would be to exchange the
order of the conditions, so the expression 'i < 31 && (1u << i) < hsize'
would remove that optimized unstable code already.
However when checking the previous lines in that function, we can deduce
that 'hsize' must always be smaller than (1u<<31), since 506049c7df2c6
(fix >4GiB source delta assertion failure), because 'entries' is
capped at an upper bound of 0xfffffffeU, so 'hsize' contains a maximum
value of 0x3fffffff, which is smaller than (1u<<31), so the value of
'i' will never be larger than 31 and we can remove that condition
entirely.

Symlink contents in p4 print sometimes have a trailing

should only remove the last character if that character
is '\n'.

If we have an old organization (v1.8.3), and want to upgrade to a newer
one (v1.8.4), the user would have to fetch the whole repository, instead
we can just move the repository, so the user would not notice any
difference.
Also, remove other clones, so in time they get set up as shared.

6796d49 (remote-hg: use a shared repository store) introduced a bug by
making the shared repository '.git/hg', which is already used before
that patch, so clones that happened before that patch, fail after that
patch, because there's no shared Mercurial repo.
So, instead of simply checking if the directory exists, let's always try
to create an empty shared repository to ensure it's there. This works
because we don't need the initial clone, if the repository is shared,
pulling from the child updates the parent's storage; it's exactly the
same as cloning, so we can simplify the shared repo setup this way while
at the same time fixing the problem.

As of 7612a1efdb (2006-06-09 git-rm: honor -n flag.) the variable
'pathspec' seems to be assumed to be never NULL after calling get_pathspec
There was a NULL pointer check after the seen = NULL assignment, which
was removed by that commit. So if pathspec would be NULL now, we'd segfault
in the line accessing the pathspec:
for (i = 0; pathspec[i] ; i++)
A few lines later, 'pathspec' still cannot be NULL, but that check was
overlooked, hence removing it now.
As the null pointer check was removed, it makes no sense to assign NULL
to seen and 3 lines later another value as there are no conditions in
between.

The condition in the ternary operator was wrong, hence the wrong char
pointer could be used as the parameter for show_submodule_summary.
one->path may be null, but we definitely need a non null path given
to the function.

The line being changed is deep inside the function builtin_diff.
The variable name_b, which is used to evaluate the ternary expression
must evaluate to true at that position, hence the replacement with
just name_b.
The name_b variable only occurs a few times in that lengthy function:
As a parameter to the function itself:
static void builtin_diff(const char *name_a,
const char *name_b,
...
The next occurrences are at:
/* Never use a non-valid filename anywhere if at all possible */
name_a = DIFF_FILE_VALID(one) ? name_a : name_b;
name_b = DIFF_FILE_VALID(two) ? name_b : name_a;
a_one = quote_two(a_prefix, name_a + (*name_a == '/'));
b_two = quote_two(b_prefix, name_b + (*name_b == '/'));
In the last line of this block 'name_b' is dereferenced and compared
to '/'. This would crash if name_b was NULL. Hence in the following code
we can assume name_b being non-null.
The next occurrence is just as a function argument, which doesn't change
the memory, which name_b points to, so the assumption name_b being not
null still holds:
emit_rewrite_diff(name_a, name_b, one, two,
textconv_one, textconv_two, o);
The next occurrence would be the line of this patch. As name_b still must
be not null, we can remove the ternary operator.
Inside the emit_rewrite_diff function there is a also a line
ecbdata.ws_rule = whitespace_rule(name_b ? name_b : name_a);
which was also simplified as there is also a dereference before the
ternary operator.

This may happen when `git gc --auto` is run automatically, then the
user, to avoid wait time, switches to a new terminal, keeps working
and `git gc --auto` is started again because the first gc instance has
not clean up the repository.
This patch tries to avoid multiple gc running, especially in --auto
mode. In the worst case, gc may be delayed 12 hours if a daemon reuses
the pid stored in gc.pid.
kill(pid, 0) support is added to MinGW port so it should work on
Windows too.

The current code fixes the path to make it absolute when cloning, but
doesn't consider tilde expansion, so that scenario fails throwing an
exception because /home/myuser/~/my/repository doesn't exists:
$ git clone hg::~/my/repository && cd repository && git fetch
Expand the tilde when checking if the path is absolute, so that we don't
fix a path that doesn't need to be.

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.

Now that close_one_pack() has been introduced to handle file
descriptor pressure, it is not strictly necessary to close the
pack file descriptor in unuse_one_window() when we're under memory
pressure.
Jeff King provided a justification for leaving the pack file open:
If you close packfile descriptors, you can run into racy situations
where somebody else is repacking and deleting packs, and they go away
while you are trying to access them. If you keep a descriptor open,
you're fine; they last to the end of the process. If you don't, then
they disappear from under you.
For normal object access, this isn't that big a deal; we just rescan
the packs and retry. But if you are packing yourself (e.g., because
you are a pack-objects started by upload-pack for a clone or fetch),
it's much harder to recover (and we print some warnings).
Let's do so (or uh, not do so).
