test-lib: provide case insensitivity as a prerequisite
Case insensitivity plays a role in several tests and is tested in several
tests. Therefore, move the test from t003 into the test lib and use the
prerequisite in t0003.

The test prerequisite mechanism is a useful way to allow some tests
in a test script to be skipped in environments that do not support
certain features (e.g. it is pointless to attempt checking how well
symbolic links are handled by Git on filesystems that do not support
them). It is OK for commonly used prerequisites to be always tested
during start-up of a test script by having a codeblock that tests a
feature and calls test_set_prereq, but for an uncommon feature,
forcing 90% of scripts to pay the same probing overhead for
prerequisite they do not care about is wasteful.
Introduce a mechanism to probe the prerequiste lazily. Changes are:
- test_lazy_prereq () function, which takes the name of the
prerequisite it probes and the script to probe for it, is
added. This only registers the name of the prerequiste that can
be lazily probed and the script to eval (without running).
- test_have_prereq() function (which is used by test_expect_success
and also can be called directly by test scripts) learns to look
at the list of prerequisites that can be lazily probed, and the
prerequisites that have already been probed that way. When asked
for a prerequiste that can be but haven't been probed, the script
registered with an earlier call to test_lazy_prereq is evaluated
and the prerequisite is set.
- test_run_lazy_prereq_() function is a helper to run the probe
script with the same kind of sandbox as regular tests, helped by
Jeff King.
Update the codeblock to probe and set SYMLINKS prerequisite using
the new mechanism as an example.
All other shell variables that are used to globally keep track of
states related to prerequisite have "prereq" somewhere in their
names. Be consistent and avoid potential name crashes with other
kinds of satisfaction in the future.

In commit f20f387, "git commit" notices and dies much
earlier when we have a bogus commit identity. That commit
did not add a test because we cannot do so reliably (namely,
we can only trigger the behavior on a system where the
automatically generated identity is bogus). However, now
that we have a prerequisite check for this feature, we can
add a test that will at least run on systems that produce
such a bogus identity.

t7502: handle systems where auto-identity is broken
Test t7502.21 checks whether we write the committer name
into COMMIT_EDITMSG when it has been automatically
determined. However, not all systems can produce valid
automatic identities.
Prior to f20f387 (commit: check committer identity more
strictly), this test worked even when we did not have a
valid automatic identity, since it did not run the strict
test until after we had generated the template. That commit
tightened the check to fail early (since we would fail
later, anyway), meaning that systems without a valid GECOS
name or hostname would fail the test.
We cannot just work around this, because it depends on
configuration outside the control of the test script.
Therefore we introduce a new test_prerequisite to run this
test only on systems where automatic ident works at all.
As a result, we can drop the confusing test_must_fail bit
from the test. The intent was that by giving "git commit"
invalid input (namely, nothing to commit), that it would
stop at a predictable point, whether we had a valid identity
or not, from which we could view the contents of
COMMIT_EDITMSG. Since that assumption no longer holds, and
we can only run the test when we have a valid identity,
there is no reason not to let commit run to completion. That
lets us be more robust to other unforeseen failures.

In t7502.20, we run "git commit" and check that it warns us
that the author and committer identity are not the same
(this is always the case in the test environment, since we
set up the idents differently).
Instead of actually making a commit, we have a clean index,
so the "git commit" we run will fail. This is marked as
might_fail, which is not really correct; it will always fail
since there is nothing to commit.
However, the only reason not to do a complete commit would
be to see the intermediate state of the COMMIT_EDITMSG file
when the commit is not completed. We don't need to care
about this, though; even a complete commit will leave
COMMIT_EDITMSG for us to view. By doing a real commit and
dropping the might_fail, we are more robust against other
unforeseen failures of "git commit" that might influence our
test result.
It might seem less robust to depend on the fact that "git
commit" leaves COMMIT_EDITMSG in place after a successful
commit. However, that brings this test in line with others
parts of the script, which make the same assumption.
Furthermore, if that ever does change, the right solution is
not to prevent commit from completing, but to set EDITOR to
a script that will record the contents we see. After all,
the point of these tests is to check what the user sees in
their EDITOR, so that would be the most direct test. For
now, though, we can continue to use the "shortcut" that
COMMIT_EDITMSG is left intact.

When we are leaving a detached HEAD, we do a revision traversal to
check whether we are orphaning any commits, marking the commit we're
leaving as the start of the traversal, and all existing refs as
uninteresting.
Prior to commit 468224e5, we did so by calling for_each_ref, and
feeding each resulting refname to setup_revisions. Commit 468224e5
refactored this to simply mark the pending objects, saving an extra
lookup.
However, it confused the "flags" parameter to the each_ref_fn
clalback, which is about the flags we found while looking up the ref
with the object flag. Because REF_ISSYMREF ("this ref is a symbolic
ref, e.g. refs/remotes/origin/HEAD") happens to be the same bit
pattern as SEEN ("we have picked this object up from the pending
list and moved it to revs.commits list"), we incorrectly reported
that a commit previously at the detached HEAD will become
unreachable if the only ref that can reach the commit happens to be
pointed at by a symbolic ref.

The combination of GIT_DIR and GIT_WORK_TREE can be used to manage
files in one directory hierarchy while keeping the repository that
keeps track of them outside the directory hierarchy. For example:
git init --bare /path/to/there
alias dotfiles="GIT_DIR=/path/to/there GIT_WORK_TREE=/path/to/here git"
cd /path/to/here
dotfiles add file
dotfiles commit -a -m "add /path/to/here/file"
...
lets you manage files under /path/to/here/ in the repository located
at /path/to/there.
git-submodule however fails to add submodules, as it is confused by
GIT_DIR and GIT_WORK_TREE environment variables when it tries to
work in the submodule, like so:
dotfiles submodule add http://path.to/submodule
fatal: working tree '/path/to/here' already exists.
Simply unsetting the environment where the command works on the
submodule is sufficient to fix this, as it has set things up so
that GIT_DIR and GIT_WORK_TREE do not even have to point at the
repository and the working tree of the submodule.

then Apache will complain when GIT_VALGRIND is not set. If
we try:

then when GIT_VALGRIND is not set, it will pass through the
literal "${GIT_VALGRIND}". Instead, we now unconditionally

In the same spirit as bf73fc2 (difftool: print list of valid tools

the tools do to be specified there, and refer them to --tool-help

The identity of the committer will ultimately be pulled from
the ident code by commit_tree(). However, we make an attempt
to check the author and committer identity early, before the
user has done any manual work like inputting a commit
message. That lets us abort without them having to worry
about salvaging the work from .git/COMMIT_EDITMSG.
The early check for committer ident does not use the
IDENT_STRICT flag, meaning that it would not find an empty
name field. The motivation was presumably because we did not
want to be too restrictive, as later calls might be more lax
(for example, when we create the reflog entry, we do not
care too much about a real name). However, because
commit_tree will always get a strict identity to put in the
commit object itself, there is no point in being lax only to
die later (and in fact it is harmful, because the user will
have wasted time typing their commit message).
Incidentally, this bug was masked prior to 060d4bb, as the
initial loose call would taint the later strict call. So the
commit would succeed (albeit with a bogus committer line in
the commit object), and nobody noticed that our early check
did not match the later one.

block-sha1: avoid pointer conversion that violates alignment constraints
With 660231aa (block-sha1: support for architectures with memory
alignment restrictions, 2009-08-12), blk_SHA1_Update was modified to
access 32-bit chunks of memory one byte at a time on arches that
prefer that:
The code previously accessed these values by just using htonl(*p).
Unfortunately, Michael noticed on an Alpha machine that git was using
plain 32-bit reads anyway. As soon as we convert a pointer to int *,
the compiler can assume that the object pointed to is correctly
aligned as an int (C99 section 6.3.2.3 "pointer conversions"
paragraph 7), and gcc takes full advantage by using a single 32-bit
load, resulting in a whole bunch of unaligned access traps.
So we need to obey the alignment constraints even when only dealing
with pointers instead of actual values. Do so by changing the type
of 'data' to void *. This patch renames 'data' to 'block' at the same
time to make sure all references are updated to reflect the new type.

our tests to avoid unnecessary breakages in tests.
* vr/use-our-perl-in-tests:
t/README: add a bit more Don'ts
tests: enclose $PERL_PATH in double quotes
t/test-lib.sh: export PERL_PATH for use in scripts
t: Replace 'perl' by $PERL_PATH
* as/t4012-style-updates:
t4012: Use test_must_fail instead of if-else
t4012: use 'printf' instead of 'dd' to generate a binary file
t4012: Re-indent test snippets
t4012: Make --shortstat test more robust
t4012: Break up pipe into serial redirections
t4012: Actually quote the sed script
t4012: Unquote git command fragment in test title
t4012: modernize style for quoting
When "git submodule add" clones a submodule repository, it can get
confused where to store the resulting submodule repository in the
superproject's .git/ directory when there is a symbolic link in the
path to the current directory.

submodules: don't stumble over symbolic links when cloning recursively
Teaches the object name parser things like a "git describe" output
is always a commit object, "A" in "git log A" must be a committish,
and "A" and "B" in "git log A...B" both must be committish, etc., to
prolong the lifetime of abbreviated object names.
* jc/sha1-name-more: (27 commits)
t1512: match the "other" object names
t1512: ignore whitespaces in wc -l output
rev-parse --disambiguate=<prefix>
rev-parse: A and B in "rev-parse A..B" refer to committish
reset: the command takes committish
commit-tree: the command wants a tree and commits
apply: --build-fake-ancestor expects blobs
sha1_name.c: add support for disambiguating other types
revision.c: the "log" family, except for "show", takes committish
revision.c: allow handle_revision_arg() to take other flags
sha1_name.c: introduce get_sha1_committish()
sha1_name.c: teach lookup context to get_sha1_with_context()
sha1_name.c: many short names can only be committish
sha1_name.c: get_sha1_1() takes lookup flags
sha1_name.c: get_describe_name() by definition groks only commits
sha1_name.c: teach get_short_sha1() a commit-only option
sha1_name.c: allow get_short_sha1() to take other flags
get_sha1(): fix error status regression
sha1_name.c: restructure disambiguation of short names
sha1_name.c: correct misnamed "canonical" and "res"

In 1.7.9 era, we taught "git rebase" about the raw timestamp format
but we did not teach the same trick to "filter-branch", which rolled
a similar logic on its own. Because of this, "filter-branch" failed
to rewrite commits with ancient timestamps.
* jc/maint-filter-branch-epoch-date:
t7003: add test to filter a branch with a commit at epoch
date.c: Fix off by one error in object-header date parsing
filter-branch: do not forget the '@' prefix to force git-timestamp
difftool: only copy back files modified during directory diff
When 'difftool --dir-diff' is used to compare working tree files,
it always copies files from the tmp dir back to the working tree
when the diff tool is closed, even if the files were not modified
by the diff tool.
This causes the file timestamp to change. Files should only be
copied from the tmp dir back to the working copy if they were
actually modified.

build: reconfigure automatically if configure.ac changes
This provides a reduced but still useful sibling of the Automake's
"automatic Makefile rebuild" feature. It's important to note that
we take care to enable the new rules only if the tree that has already
be configured with './configure', so that users relying on manual
configuration won't be negatively impacted.

build: "make clean" should not remove configure-generated files
Those filed hold variables, settings and information set by the
configuration process run by './configure'; in Autotools-based
build system that kind of stuff should only be removed by
"make distclean". Having it removed by "make clean" is not only
inconsistent, but causes real confusion for that part of the Git
audience that is used to the Autotools semantics; for example,
an autotools old-timer that has run:
./configure --prefix /opt/git
in the past, without running "make distclean" afterwards, would
expect a "make install" issued after a "make clean" to rebuild and
install git in '/opt/git'; but with the current behaviour, the
"make clean" invocation removes (among the other things) the file
'config.mak.autogen', so that the "make install" falls back to the
default prefix of '$HOME', thus installing git in the user's home
directory -- definitely unexpected.

autoconf: use AC_CONFIG_COMMANDS instead of ad-hoc 'config.mak.append'
This will allow "./config.status --recheck; ./config.status" to work
correctly as a mean of reconfiguring the tree with the same configure
argument used in the previous "./configure" invocation.

The new name fits better with the macro signature, and underlines the
similarities with the autoconf-provided macro AC_SUBST (which will be
made even more pronounced in planned future commits).
Once again, no semantic change is intended, and indeed no change to the
generated configure script is expected.
