ab62677b14 require_work_tree broken with NONGIT_OK
With NONGIT_OK set, require_work_tree function outside a git repository
gives a syntax error.  This is caused by an incorrect use of "test" that
didn't anticipate $(git rev-parse --is-inside-work-tree) may return an
empty string.

Properly quote the argument to "test", and send the standard error stream
to /dev/null to avoid giving duplicate error messages.

f6dff119d5 am: Fix launching of pager
The pagination functionality in git am has some problems:

 - It does not check if stdout is a tty, so it always paginates.

 - If $GIT_PAGER uses any environment variables, they are being
   ignored, since it does not run $GIT_PAGER through eval.

 - If $GIT_PAGER is set to the empty string, instead of passing
   output through to stdout, it tries to run $dotest/patch.

Fix them.  While at it, move the definition of git_pager() to
git-sh-setup so authors of other commands are not tempted to
reimplement it with the same mistakes.

46bac90458 Do not install shell libraries executable
Some scripts are expected to be sourced instead of executed on their own.
Avoid some confusion by not marking them executable.

The executable bit was confusing the valgrind support of our test scripts,
which assumed that any executable without a #!-line should be intercepted
and run through valgrind.  So during valgrind-enabled tests, any script
sourcing these files actually sourced the valgrind interception script
instead.

91dc602de9 Use $(git rev-parse --show-toplevel) in cd_to_toplevel().
rev-parse --show-toplevel gives the absolute (aka "physical") path of the
toplevel directory and is more portable as 'cd -P' is not supported by all
shell implementations.

This is also closer to what setup_work_tree() does.

e1622bfcba Protect scripted Porcelains from GREP_OPTIONS insanity
If the user has exported the GREP_OPTIONS environment variable, the output
from "grep" and "egrep" in scripted Porcelains may be different from what
they expect.  For example, we may want to count number of matching lines,
by "grep" piped to "wc -l", and GREP_OPTIONS=-C3 will break such use.

The approach taken by this change to address this issue is to protect only
our own use of grep/egrep.  Because we do not unset it at the beginning of
our scripts, hook scripts run from the scripted Porcelains are exposed to
the same insanity this environment variable causes when grep/egrep is used
to implement logic (e.g. "grep | wc -l"), and it is entirely up to the
hook scripts to protect themselves.

On the other hand, applypatch-msg hook may want to show offending words in
the proposed commit log message using grep to the end user, and the user
might want to set GREP_OPTIONS=--color to paint the match more visibly.
The approach to protect only our own use without unsetting the environment
variable globally will allow this use case.

61dbb3c441 Makefile: insert SANE_TOOL_PATH to PATH before /bin or /usr/bin
In an earlier patch, we introduced SANE_TOOL_PATH that is prepended to
user's PATH.  This had an unintended consequence of overriding user's
private binary directory that typically comes earlier in the PATH to holds
even saner commands than whatever comes with the system.

For example, a user may have ~/bin that is early in the path and contains
a shell script "vi" that launches system's /bin/vi with specific options.
Prepending SANE_TOOL_PATH to the PATH that happens to have "vi" in it
defeats such customization.

This fixes the issue by inserting SANE_TOOL_PATH just before /bin or
/usr/bin appears on the PATH.

0e0aea5a47 Makefile: introduce SANE_TOOL_PATH for prepending required elements to PATH
Some platforms (like SunOS and family) have kept their common binaries at
some historical moment in time, and introduced new binaries with modern
features in a special location like /usr/xpg4/bin or /usr/ucb.  Some of the
features provided by these modern binaries are expected and required by git.
If the featureful binaries are not in the users path, then git could end up
using the less featureful binary and fail.

So provide a mechanism to prepend elements to the users PATH at runtime so
the modern binaries will be found.

2c3c395e84 git-sh-setup: Use "cd" option, not /bin/pwd, for symlinked work tree
In cd_to_toplevel, instead of 'cd $(unset PWD; /bin/pwd)/$path'
use 'cd -P $path'.  The "-P" option yields a desirable similarity to
C chdir.

While the "-P" option may be slightly less commonly supported than
/bin/pwd, it is more concise, better tested, and less error prone.
I've already added the 'unset PWD' to fix the /bin/pwd solution on
BSD; there may be more edge cases out there.

This still passes all the same test cases in t5521-pull-symlink.sh and
t2300-cd-to-toplevel.sh, even before updating them to use 'pwd -P'.

dd6c1360b2 git-sh-setup: Fix scripts whose PWD is a symlink to a work-dir on OS X
On Mac OS X and possibly BSDs, /bin/pwd reads PWD from the environment if
available and shows the logical path by default rather than the physical
one.

Unset PWD before running /bin/pwd in both cd_to_toplevel and its test.

Still use the external /bin/pwd because in my Bash on Linux, the builtin
pwd prints the same result whether or not PWD is set.

08fc060865 git-sh-setup: Fix scripts whose PWD is a symlink into a git work-dir
I want directories of my working tree to be linked to from various
paths on my filesystem where third-party components expect them, both
in development and production environments.  A build system's install
step could solve this, but I develop scripts and web pages that don't
need to be built.  Git's submodule system could solve this, but we
tend to develop, branch, and test those directories all in unison, so
one big repository feels more natural.  We prefer to edit and commit
on the symlinked paths, not the canonical ones, and in that setting,
"git pull" fails to find the top-level directory of the repository
while other commands work fine.

"git pull" fails because POSIX shells have a notion of current working
directory that is different from getcwd().  The shell stores this path
in PWD.  As a result, "cd ../" can be interpreted differently in a
shell script than chdir("../") in a C program.  The shell interprets
"../" by essentially stripping the last textual path component from
PWD, whereas C chdir() follows the ".." link in the current directory
on the filesystem.  When PWD is a symlink, these are different
destinations.  As a result, Git's C commands find the correct
top-level working tree, and shell scripts do not.

Changes:

* When interpreting a relative upward (../) path in cd_to_toplevel,
  prepend the cwd without symlinks, given by /bin/pwd
* Add tests for cd_to_toplevel and "git pull" in a symlinked
  directory that failed before this fix, plus contrasting scenarios
  that already worked

077b725f0b Protect get_author_ident_from_commit() from filenames in work tree
We used to use "cat-file commit $commit" to extract the original
author information from existing commit, but an earlier commit
5ac2715 (Consistent message encoding while reusing log from an
existing commit) changed it to use "git show -s $commit".  If
you have a file in your work tree that can be interpreted as a
valid object name (e.g. "HEAD"), this conversion will not work.

Disambiguate by marking the end of revision parameter on the
comand line with an explicit "--" to fix this.

"HEAD" exists in the worktree.

70087cdbd3 git-help: add "help.format" config variable.
This config variable makes it possible to choose the default format
used to display help. This format will be used only if no option
like -a|--all|-i|--info|-m|--man|-w|--web is passed to "git-help".

The following values are possible for this variable:

	- "man"  --> "man" program is used
	- "info" --> "info" program is used
	- "web"  --> "git-browse-help" is used

By default we still show help using "man".

This patch also adds -m|--man command line option to use "man"
to allow overriding the "help.format" configuration variable.

Note that this patch also revert some recent changes in
"git-browse-help" because they prevented to look for config
variables in the global configuration file.

b2bc9a3098 git-sh-setup.sh: make GIT_DIR absolute

Some try their hands (with different likelihood of success) in making
GIT_DIR absolute.

This patch lets git-sh-setup.sh cater for absolute directories (in a

08874658b4 git-sh-setup.sh: make GIT_EDITOR/core.editor/VISUAL/EDITOR accept commands
The previous code only allowed specifying a single executable rather
than a complete command like "emacsclient --alternate-editor vi" in
those variables.  Since VISUAL/EDITOR appear to be traditionally
passed to a shell for interpretation (as corroborated with "less",
"mail" and "mailx", while the really ancient "more" indeed allows only
an executable name), the shell function git_editor has been amended
appropriately.

"eval" is employed to have quotes and similar interpreted _after_
expansion, so that specifying
EDITOR='"/home/dak/My Commands/notepad.exe"'
can be used for actually using commands with blanks.

Instead of passing just the first argument of git_editor on, we pass
all of them (so that +lineno might be employed at a later point of
time, or so that multiple files may be edited when appropriate).

Strictly speaking, there is a change in behavior: when
git config core.editor
returns a valid but empty string, the fallbacks are still searched.
This is more consistent, and the old code was problematic with regard
to multiple blanks.  Putting in additional quotes might have worked,
but quotes inside of command substitution inside of quotes is nasty
enough to not reliably work the same across "Bourne shells".

e90fdc39b6 Clean up work-tree handling
The old version of work-tree support was an unholy mess, barely readable,
and not to the point.

For example, why do you have to provide a worktree, when it is not used?
As in "git status".  Now it works.

Another riddle was: if you can have work trees inside the git dir, why
are some programs complaining that they need a work tree?

IOW it is allowed to call

	$ git --git-dir=../ --work-tree=. bla

when you really want to.  In this case, you are both in the git directory
and in the working tree.  So, programs have to actually test for the right
thing, namely if they are inside a working tree, and not if they are
inside a git directory.

Also, GIT_DIR=../.git should behave the same as if no GIT_DIR was
specified, unless there is a repository in the current working directory.
It does now.

The logic to determine if a repository is bare, or has a work tree
(tertium non datur), is this:

--work-tree=bla overrides GIT_WORK_TREE, which overrides core.bare = true,
which overrides core.worktree, which overrides GIT_DIR/.. when GIT_DIR
ends in /.git, which overrides the directory in which .git/ was found.

In related news, a long standing bug was fixed: when in .git/bla/x.git/,
which is a bare repository, git formerly assumed ../.. to be the
appropriate git dir.  This problem was reported by Shawn Pearce to have
caused much pain, where a colleague mistakenly ran "git init" in "/" a
long time ago, and bare repositories just would not work.

was starting to get out of control, as most porcelain code
needed to hand it to other porcelain and plumbing alike to
ensure the reflog contained the top-level user action and
not the lower-level actions it invoked.

At Junio's suggestion we are introducing the new set_reflog_action
function to all shell scripts, allowing them to declare early on
what their default reflog name should be, but this setting only
takes effect if the caller has not already set the GIT_REFLOG_ACTION

4890f62bc0 Avoid using "git-var -l" until it gets fixed.
This is to be nicer to people with unusable GECOS field.

"git-var -l" is currently broken in that when used by a user who
does not have a usable GECOS field and has not corrected it by
exporting GIT_COMMITTER_NAME environment variable it dies when
it tries to output GIT_COMMITTER_IDENT (same thing for AUTHOR).

"git-pull" used "git-var -l" only because it needed to get a
configuration variable before "git-repo-config --get" was
introduced.  Use the latter tool designed exactly for this
purpose.

"git-sh-setup" used "git-var GIT_AUTHOR_IDENT" without actually
wanting to use its value.  The only purpose was to cause the
command to check and barf if the repository format version
recorded in the $GIT_DIR/config file is too new for us to deal
with correctly.  Instead, use "repo-config --get" on a random
property and see if it die()s, and check if the exit status is
128 (comes from die -- missing variable is reported with exit
status 1, so we can tell that case apart).

d025524d9d Usage message clean-up, take #2
There were some problems with the usage message clean-up patch
series. I hadn't realised that subdirectory aware scripts can't source
git-sh-setup. I propose that we change this and let the scripts which
are subdirectory aware set a variable, SUBDIRECTORY_OK, before they
source git-sh-setup.

The scripts will also set USAGE and possibly LONG_USAGE before they
source git-sh-setup. If LONG_USAGE isn't set it defaults to USAGE.

If we go this way it's easy to catch --help in git-sh-setup, print the
(long) usage message to stdout and exit cleanly. git-sh-setup can
define a 'usage' shell function which can be called by the scripts to
print the short usage string to stderr and exit non-cleanly. It will
also be easy to change $0 to basename $0 or something else, if would
like to do that sometime in the future.

What follows is a patch to convert a couple of the commands to this
style. If it's ok with everyone to do it this way I will convert the
rest of the scripts too.

[jc: thrown in to proposed updates queue for comments.]

2a1ddc58e4 git-sh-setup: move the repository check to a core program.
Any core commands that use setup_git_directory() now check if
given GIT_DIR is really a valid repository, so the same check in
git-sh-setup can use it without reimplementing it in shell.
This commit changes git-sh-setup to use git-var command for
that, although any other commands would do.

Note that we export GIT_DIR explicitly when calling git-var;
without it, the caller of this script would use GIT_DIR that we
return (which is to assume ./.git unless the caller has it
elsewhere) while git-var would go up to find a .git directory in
our parent directories, which would be checking a different
directory from what our callers will be using.

ae2b0f1518 git-sh-setup: die if outside git repository.
Now all the users of this script detect its exit status and die,
complaining that it is outside git repository.  So move the code
that dies from all callers to git-sh-setup script.

230f13225d Create object subdirectories on demand
This makes it possible to have a "sparse" git object subdirectory
structure, something that has become much more attractive now that people
use pack-files all the time.

As a result of pack-files, a git object directory doesn't necessarily have
any individual objects lying around, and in that case it's just wasting
space to keep the empty first-level object directories around: on many
filesystems the 256 empty directories will be aboue 1MB of diskspace.

Even more importantly, after you re-pack a project that _used_ to be
unpacked, you could be left with huge directories that no longer contain
anything, but that waste space and take time to look through.

With this change, "git prune-packed" can just do an rmdir() on the
directories, and they'll get removed if empty, and re-created on demand.

This patch also tries to fix up "write_sha1_from_fd()" to use the new
common infrastructure for creating the object files, closing a hole where
we might otherwise leave half-written objects in the object database.

[jc: I unoptimized the part that really removes the fan-out directories
 to ease transition.  init-db still wastes 1MB of diskspace to hold 256
 empty fan-outs, and prune-packed rmdir()'s the grown but empty directories,
 but runs mkdir() immediately after that -- reducing the saving from 150KB
 to 146KB.  These parts will be re-introduced when everybody has the
 on-demand capability.]

8098a178b2 Add git-symbolic-ref
This adds the counterpart of git-update-ref that lets you read
and create "symbolic refs".  By default it uses a symbolic link
to represent ".git/HEAD -> refs/heads/master", but it can be compiled
to use the textfile symbolic ref.

The places that did 'readlink .git/HEAD' and 'ln -s refs/heads/blah
.git/HEAD' have been converted to use new git-symbolic-ref command, so
that they can deal with either implementation.

e2f5f6ef67 Do not require clean tree when reverting and cherry-picking.
My stupidity deserved to be yelled at by Linus ... there is no reason
to require the working tree to be clean when merging -- the only
requirements are index to match HEAD commit and the paths involved in
merge are up to date in the working tree.  Revert and cherry-pick are
just specialized forms of merge, and the requirements should be the
same.

Remove the 'general purpose routine to make sure tree is clean' from
git-sh-setup, to prevent me from getting tempted again.

365527adbf Fix CDPATH problem.
CDPATH has two problems:

 * It takes scripts to unexpected places (somebody had
   CDPATH=..:../..:$HOME and the "cd" in git-clone.sh:get_repo_base
   took him to $HOME/.git when he said "clone foo bar" to clone a
   repository in "foo" which had "foo/.git").  CDPATH mechanism does
   not implicitly give "." at the beginning of CDPATH, which is
   the most irritating part.

 * The extra echo when it does its thing confuses scripts further.

Most of our scripts that use "cd" includes git-sh-setup so the problem
is primarily fixed there.  git-clone starts without a repository, and
it needs its own fix.

215a7ad1ef Big tool rename.
As promised, this is the "big tool rename" patch.  The primary differences
since 0.99.6 are:

  (1) git-*-script are no more.  The commands installed do not
      have any such suffix so users do not have to remember if
      something is implemented as a shell script or not.

  (2) Many command names with 'cache' in them are renamed with
      'index' if that is what they mean.

There are backward compatibility symblic links so that you and
Porcelains can keep using the old names, but the backward
compatibility support  is expected to be removed in the near
future.
