t0060: split absolute path test in two to exercise some of it on Windows
Only the first half of the test works only on POSIX, the second half
passes on Windows as well.
A later test "real path removes other extra slashes" looks very similar,
but it does not make sense to split it in the same way: When two slashes
are prepended in front of an absolute DOS-style path on Windows, the
meaning of the path is changed (//server/share style), so that the test
cannot pass on Windows.

real_path(): properly handle nonexistent top-level paths
The change has two points:
1. Do not strip off a leading slash, because that erroneously turns an
absolute path into a relative path.
2. Do not remove slashes from groups of multiple slashes; instead let
chdir() handle them. It could be, for example, that it wants to
leave leading double-slashes alone.

t0060: verify that real_path() works correctly with absolute paths
There is currently a bug: if passed an absolute top-level path that
doesn't exist (e.g., "/foo") it incorrectly interprets the path as a
relative path (e.g., returns "$(pwd)/foo"). So mark the test as
failing.
These tests are skipped on Windows because test-path-utils operates on
a DOS-style absolute path even if a POSIX style absolute path is
passed as argument.

terminal: seek when switching between reading and writing
When a stdio stream is opened in update mode (e.g., "w+"),
the C standard forbids switching between reading or writing
without an intervening positioning function. Many
implementations are lenient about this, but Solaris libc
will flush the recently-read contents to the output buffer.
In this instance, that meant writing the non-echoed password
that the user just typed to the terminal.
Fix it by inserting a no-op fseek between the read and
write.
The opposite direction (writing followed by reading) is also
disallowed, but our intervening fflush is an acceptable

We already purged it in
b3431bc (Don't use seq in tests, not
everyone has it, 2007-05-02), but a few new instances have crept
in. They went unnoticed because they are in scripts that are not
run by default.
Replace them with test_seq that is implemented with a Perl snippet
(proposed by Jeff). This is better than inlining this snippet
everywhere it's needed because it's easier to read and it's easier
to change the implementation (e.g. to C) if we ever decide to remove
Perl from the test suite.
Note that test_seq is not a complete replacement for seq(1). It
just has what we need now, in addition that it makes it possible for
us to do something like "test_seq a m" if we wanted to in the
future.
There are also many places that do `for i in 1 2 3 ...` but I'm not sure
if it's worth converting them to test_seq. That would introduce running
more processes of Perl.

checkout: don't confuse ref and object flags

check whether we are orphaning any commits, marking the commit we're

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

commit: check committer identity more strictly
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.

advice: pass varargs to strbuf_vaddf, not strbuf_addf

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:
#define get_be32(p) ( \
(*((unsigned char *)(p) + 0) << 24) | \
(*((unsigned char *)(p) + 1) << 16) | \
(*((unsigned char *)(p) + 2) << 8) | \
(*((unsigned char *)(p) + 3) << 0) )
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.

diff: test precedence of external diff drivers
There are three ways to specify an external diff command:
GIT_EXTERNAL_DIFF in the environment, diff.external in the
config, or a "diff" gitattribute. The current order of
precedence is:
1. gitattribute
2. GIT_EXTERNAL_DIFF
3. diff.external
Usually our rule is that environment variables should take
precedence over on-disk config (i.e., option 2 should come
before option 1). However, this situation is trickier than
some, because option 1 is more specific to the individual
file than option 2 (which affects all files), so it might be
preferable. So the current behavior can be seen as
implementing "do the specific thing if we can, but fall back
to this general thing".
This is probably not what we would do if we were writing git
from scratch, but it has been this way for several years,
and is not worth changing. So let's at least document that
this is the way it's supposed to work with a test.
While we're there, let's also make sure that diff.external
(which was not previously tested at all) works by running it
through the same tests as GIT_EXTERNAL_DIFF.

This is because the logic to disable external diff was placed at a
wrong level in the callchain. run_diff_cmd() decides to show the
split patch only when external diff driver is not configured or
specified via GIT_EXTERNAL_DIFF environment, but this is done before
checking if --no-ext-diff was given. To make things worse,
run_diff_cmd() checks --no-ext-diff and disables the output for such

Since
69c3051 (submodules: refactor computation of relative gitdir path)
cloning a submodule recursively fails for nested submodules when a
symbolic link is part of the path to the work tree of the superproject.
This happens when module_clone() tries to find the relative paths between
the work tree and the git dir. When a symbolic link in current $PWD points
to a directory that is at a different level, then determining the number
of "../" needed to traverse to the superproject's work tree leads to a
wrong result.
As there is no portable way to say "pwd -P", use cd_to_toplevel to remove
the link from $PWD, which fixes this problem.
