Add support for dividing the refs of a single repository into multiple
namespaces, each of which can have its own branches, tags, and HEAD.
Git can expose each namespace as an independent repository to pull from
and push to, while sharing the object store, and exposing all the refs
to operations such as git-gc.
Storing multiple repositories as namespaces of a single repository
avoids storing duplicate copies of the same objects, such as when
storing multiple branches of the same source. The alternates mechanism
provides similar support for avoiding duplicates, but alternates do not
prevent duplication between new objects added to the repositories
without ongoing maintenance, while namespaces do.
To specify a namespace, set the GIT_NAMESPACE environment variable to
the namespace. For each ref namespace, git stores the corresponding
refs in a directory under refs/namespaces/. For example,
GIT_NAMESPACE=foo will store refs under refs/namespaces/foo/. You can
also specify namespaces via the --namespace option to git.
Note that namespaces which include a / will expand to a hierarchy of
namespaces; for example, GIT_NAMESPACE=foo/bar will store refs under
refs/namespaces/foo/refs/namespaces/bar/. This makes paths in
GIT_NAMESPACE behave hierarchically, so that cloning with
GIT_NAMESPACE=foo/bar produces the same result as cloning with
GIT_NAMESPACE=foo and cloning from that repo with GIT_NAMESPACE=bar. It
also avoids ambiguity with strange namespace paths such as
foo/refs/heads/, which could otherwise generate directory/file conflicts
within the refs directory.
Add the infrastructure for ref namespaces: handle the GIT_NAMESPACE
environment variable and --namespace option, and support iterating over
refs in a namespace.

The handle_options() function advances the base of the argument array and
returns the number of arguments it used. The caller in handle_alias()
wants to reallocate the argv array it passes to this function, and
attempts to do so by subtracting the returned value to compensate for the
change handle_options() makes to the new_argv.
But handle_options() did not correctly count when "-c <config=value>" is
given, causing a wrong pointer to be passed to realloc().
Fix it by saving the original argv at the beginning of handle_options(),
and return the difference between the final value of argv, which will
relieve the places that move the array pointer from the additional burden
of keeping track of "handled" counter.

We start the pager too early for several git commands, which results in
the errors sometimes going to the pager rather than show up as errors.
This is often hidden by the fact that we pass in '-X' to less by default,
which causes 'less' to exit for small output, but if you do
export LESS=-S
you can then clearly see the problem by doing
git log --prretty
which shows the error message ("fatal: unrecognized argument: --prretty")
being sent to the pager.
This happens for pretty much all git commands that use USE_PAGER, and then
check arguments separately. But "git diff" does it too early too (even
though it does an explicit setup_pager() call)
This only fixes it for the trivial "git log" family case.

This works fine for built-ins, but the config changes are

In the spirit of v1.4.2-rc3~34^2^2 (Call setup_git_directory() much
earlier, 2006-07-28), let run_builtin() take care of searching for a

So now you can mark your command with RUN_SETUP_GENTLY and use
nongit = !startup_info->have_repository;
in place of
prefix = setup_git_directory_gently(&nongit);
and everything will be the same, except the repository is
discovered a little sooner.

The startup_info struct will collect information managed by the git
setup code, such as the prefix for relative paths passed on the
command line (i.e., path to the starting cwd from the toplevel of
the work tree) and whether a git repository has been found.
In other words, startup_info is intended to be a collection of global
variables with results that were previously returned from setup
functions. This state is global anyway (since the cwd is), even
if it is not currently tracked that way. Letting these values persist
means there is more flexibility in deciding when to run setup.
For now, the struct is empty.

73e25e7c (git --paginate: do not commit pager choice too early,
2010-06-26) failed to take some cases into account.
1b. Builtins that do not use RUN_SETUP (like git config) do
not find GIT_DIR set correctly when the pager is launched
from run_builtin(). So the core.pager configuration is
not honored from subdirectories of the toplevel for them.
4a. External git commands (like git request-pull) relied on the
early pager launch to take care of handling the -p option.
Ever since 73e25e7c, they do not honor the -p option at all.
4b. Commands invoked through ! aliases (like ls) were also relying
on the early pager launch.
Fix (4a) by launching the pager (if requested) before running such a
“dashed external”. For simplicity, this still does not search for a
.git directory before running the external command; when run from a
subdirectory of the toplevel, therefore, the “[core] pager”
configuration is still not honored.
Fix (4b) by launching pager if requested before carrying out such an
alias. Actually doing this has no effect, since the pager (if any)
would have already been launched in a failed attempt to try a
dashed external first. The choice-of-pager-not-honored-from-
subdirectory bug still applies here, too.

When git is passed the --paginate option, starting up a pager requires
deciding what pager to start, which requires access to the core.pager
configuration.
At the relevant moment, the repository has not been searched for yet.
Attempting to access the configuration at this point results in
git_dir being set to .git [*], which is almost certainly not what was
wanted. In particular, when run from a subdirectory of the toplevel,
git --paginate does not respect the core.pager setting from the
current repository.
[*] unless GIT_DIR or GIT_CONFIG is set
So delay the pager startup when possible:
1. run_argv() already commits pager choice inside run_builtin() if a
command is found. For commands that use RUN_SETUP, waiting until
then fixes the problem described above: once git knows where to
look, it happily respects the core.pager setting.
2. list_common_cmds_help() prints out 29 lines and exits. This can
benefit from pagination, so we need to commit the pager choice
before writing this output.
Luckily ‘git’ without subcommand has no other reason to access a
repository, so it would be intuitive to ignore repository-local
configuration in this case. Simpler for now to choose a pager
using the funny code that notices a repository that happens to be
at .git. That this accesses a repository when it is very
convenient to is a bug but not an important one.
3. help_unknown_cmd() prints out a few lines to stderr. It is not
important to paginate this, so don’t.

This adds an option to open the matching files in the pager, and if the
pager happens to be "less" (or "vi") and there is only one grep pattern,
it also jumps to the first match right away.
The short option was chose as '-O' to avoid clashes with GNU grep's
options (as suggested by Junio).
So, 'git grep -O abc' is a short form for 'less +/abc $(grep -l abc)'
except that it works also with spaces in file names, and it does not
start the pager if there was no matching file.

In the case where a program was not found, it was still the task of the
caller to report an error to the user. Usually, this is an interesting case
but only few callers actually reported a specific error (though many call
sites report a generic error message regardless of the cause).
With this change the error is reported by run_command, but since there is
one call site in git.c that does not want that, an option is added to
struct child_process, which is used to turn the error off.

The motivation for this change is that system call failures are serious
errors that should be reported to the user, but only few callers took the
burden to decode the error codes that the functions returned into error
messages.
If at all, then only an unspecific error message was given. A prominent
example is this:
$ git upload-pack . | :
fatal: unable to run 'git-upload-pack'
In this example, git-upload-pack, the external command invoked through the
git wrapper, dies due to SIGPIPE, but the git wrapper does not bother to
report the real cause. In fact, this very error message is copied to the
syslog if git-daemon's client aborts the connection early.
With this change, system call failures are reported immediately after the
failure and only a generic failure code is returned to the caller. In the
above example the error is now to the point:
$ git upload-pack . | :
error: git-upload-pack died of signal
Note that there is no error report if the invoked program terminated with
a non-zero exit code, because it is reasonable to expect that the invoked
program has already reported an error. (But many run_command call sites
nevertheless write a generic error message.)
There was one special return code that was used to identify the case where
run_command failed because the requested program could not be exec'd. This
special case is now treated like a system call failure with errno set to
ENOENT. No error is reported in this case, because the call site in git.c
expects this as a normal result. Therefore, the callers that carefully
decoded the return value still check for this condition.

As a general guideline, functions in git's code return zero to indicate
success and negative values to indicate failure. The run_command family of
functions followed this guideline. But there are actually two different
kinds of failure:
- failures of system calls;
- non-zero exit code of the program that was run.
Usually, a non-zero exit code of the program is a failure and means a
failure to the caller. Except that sometimes it does not. For example, the
exit code of merge programs (e.g. external merge drivers) conveys
information about how the merge failed, and not all exit calls are
actually failures.
Furthermore, the return value of run_command is sometimes used as exit
code by the caller.
This change arranges that the exit code of the program is returned as a
positive value, which can now be regarded as the "result" of the function.
System call failures continue to be reported as negative values.

For some reason, MinGW's bash cannot reliably detect failure of the child
process if a negative value is passed to exit(). This fixes it by
truncating the exit code in all calls of exit().
This issue was worked around in run_builtin() of git.c (2488df84 builtin
run_command: do not exit with -1, 2007-11-15). This workaround is no longer
necessary and is reverted.

When creating a new argv array from a configured alias and the supplied
command line arguments, the new argv was allocated with one element too
many. Since the first element of the original argv array is skipped when
copying it to the new_argv, the number of elements that are allocated
should be reduced by one. 'count' is the number of elements that new_argv
contains, and *argcp is the number of elements in the original argv array.
So the total allocation (including the terminating NULL entry) for the
new_argv array should be:
count + (*argcp - 1) + 1
Also, the explicit assignment of the NULL terminating entry can be avoided
by just copying it over from the original argv array.

This patch implements a new "git bisect--helper" builtin plumbing
command that will be used to migrate "git-bisect.sh" to C.
We start by implementing only the "--next-vars" option that will
read bisect refs from "refs/bisect/", and then compute the next
bisect step, and output shell variables ready to be eval'ed by
the shell.
At this step, "git bisect--helper" ignores the paths that may
have been put in "$GIT_DIR/BISECT_NAMES". This will be fixed in a
later patch.

We used to simply try calling execvp(); if it succeeded, then we were done
and the new program was running. If it didn't, then we knew that it wasn't
a valid command.
Unfortunately, this interacted badly with the new pager handling. Now that
git remains the parent process and the pager is spawned, git has to hang
around until the pager is finished. We install an atexit handler to do
this, but that handler never gets called if we successfully run execvp.
You could see this behavior by running any dashed external using a pager
(e.g., "git -p stash list"). The command finishes running, but the pager
is still going. In the case of less, it then gets an error reading from
the terminal and exits, potentially leaving the terminal in a broken state
(and not showing the output).
This patch just uses run_command() to try running the dashed external. The
parent git process then waits for the external process to complete and
then handles the pager cleanup as it would for an internal command.

help_unknown_cmd() is able to autocorrect a command to an alias, and not
only to internal or external commands. However, main() was not passing the
autocorrected command through handle_alias(), hence it failed if it was an
alias.
This commit makes the autocorrected command go through handle_alias(), once
handle_internal_command() and execv_dashed_external() have been tried. Since
this is done twice in main() now, moved that logic to a new run_argv()
function.
Also, print the same "Expansion of alias 'x' failed" message when the alias
was autocorrected, rather than a generic "Failed to run command 'x'".
