The printf utility provided by coreutils when interpreting '\%o' format
does not recognize %o as formatting directive. For example
printf '\%o 0 returns \%o and warning: ignoring excess arguments,
starting with ‘0’, which results in failed tests in
t5309-pack-delta-cycles.sh. In most shells the test ends with success as
the printf is a builtin utility.
Fix it by using '\\%o' which is interpreted consistently in all versions
of printf.

We have the build configuration option DEFAULT_MAN_FORMAT to choose a
format different from man pages to be used by 'git help' when no format
is requested explicitly. Since 65db0443 (Set the default help format to
html for msys builds, 2013-06-04) we use html on Windows by default.
There is one test in t3200-branch.sh that invokes a help page. The
intent of the redirections applied to the command invocation is to avoid
that the man page viewer interferes with the automated test. But when
the default format is not "man", this does not have the intended effect,
and the HTML manual page is opened during the test run. Request "man"
format explicitly to keep the test silent.

The Makefile currently builds the roff manpage, but not the

This patch does not build or install it as part of

Solaris' tr (both /usr/bin/ and /usr/xpg4/bin) uses the System V
semantics for tr whereby string1's length is truncated to the length
of string2 if string2 is shorter. The BSD semantics, as used by GNU tr
see string2 padded to the length of string1 using the final character
in string2. POSIX explicitly doesn't specify the correct behavior
here, making both equally valid.
This difference means that Solaris' native tr implementations produce
different results for tr ":\t\n" "\0" than GNU tr. This breaks a few
tests in t0008-ignores.sh.
Possible fixes for this are to make string2 be "\0\0\0" or "[\0*]".
Instead, use perl to perform these transliterations which means we
don't need to worry about the difference at all. Since we're replacing
tr with perl, we also use perl to replace the sed invocations used to
transform the files.
Replace four identical transforms with a function named
broken_c_unquote. Replace the other two identical transforms with a
fuction named broken_c_unquote_verbose.

If you ask for-each-ref to print each ref and its object,
like:
git for-each-ref --format='%(objectname) %(refname)'
this should involve little more work than looking at the ref
files (and packed-refs) themselves. However, for-each-ref
will actually load each object from disk just to print its
sha1. For most repositories, this isn't a big deal, but it
can be noticeable if you have a large number of refs to
print. Here are best-of-five timings for the command above
on a repo with ~10K refs:
[before]
real 0m0.112s
user 0m0.092s
sys 0m0.016s
[after]
real 0m0.014s
user 0m0.012s
sys 0m0.000s
This patch checks for %(objectname) and %(objectname:short)
before we actually parse the object (and the rest of the
code is smart enough to avoid parsing if we have filled all
of our placeholders).
Note that we can't simply move the objectname parsing code
into the early loop. If the "deref" form %(*objectname) is
used, then we do need to parse the object in order to peel
the tag. So instead of moving the code, we factor it out
into a separate function that can be called for both cases.
While we're at it, we add some basic tests for the
dereferenced placeholders, which were not tested at all
before. This helps ensure we didn't regress that case.

Perl 5.18 randomizes the seed used by its hash function, so iterating
through hashes results in different orders from run to run:
http://perldoc.perl.org/perl5180delta.html#Hash-overhaul
This usually broke t9400 (gitcvs.dbname, gitcvs.ext.dbname, when
running cmp on two .sqlite files) and t9402 (check [cvswork3] diff,
when running test_cmp on two diffs).
To fix this, hide the internal order of hashes with sort when sending
output or running database queries.
(An alternative workaround is PERL_HASH_SEED=0, but this seems nicer.)

As of the last commit, we can use "perl" instead of
"$PERL_PATH" when running tests, as the former is now a
function which uses the latter. As the shorter "perl" is
easier on the eyes, let's switch to using it everywhere.
This is not quite a mechanical s/$PERL_PATH/perl/
replacement, though. There are some places where we invoke
perl from a script we generate on the fly, and those scripts
do not have access to our internal shell functions. The
result can be double-checked by running:
ln -s /bin/false bin-wrappers/perl
make test
which continues to pass even after this patch.

Once upon a time, we assumed that calling a bare "perl" in
the test scripts was OK, because we would find the perl from
the user's PATH, and we were only asking that perl to do
basic operations that work even on old versions of perl.
Later, we found that some systems really prefer to use
$PERL_PATH even for these basic cases, because the system
perl misbehaves in some way (e.g., by handling line endings
differently). We then switched "perl" invocations to
"$PERL_PATH" to respect the user's choice.
Having to use "$PERL_PATH" is ugly and cumbersome, though.
Instead, let's provide a perl() shell function that tests
can use, which will transparently do the right thing.
Unfortunately, test writers still have to use $PERL_PATH in
certain situations, so we still need to keep the advice in
the README.
Note that this may fix test failures in t5004, t5503, t6002,
t6003, t6300, t8001, and t8002, depending on your system's
perl setup. All of these can be detected by running:
ln -s /bin/false bin-wrappers/perl
make test
which fails before this patch, and passes after.

The git build system supports a NO_PERL switch to avoid installing
perl bindings or other features (like "git add --patch") that rely on
perl on runtime, but even with NO_PERL it has not been possible for a
long time to run tests without perl. Helpers such as
nul_to_q () {
"$PERL_PATH" -pe 'y/\000/Q/'
}
use perl as a better tr or sed and are regularly used in tests without
worrying to add a PERL prerequisite.
Perl is portable enough that it seems fine to keep relying on it for
this kind of thing in tests (and more readable than the alternative of
trying to find POSIXy equivalents). Update the test documentation to
clarify this.

Normally parse_pathspec() is used on command line arguments where it
can do fancy thing like parsing magic on each argument or adding magic
for all pathspecs based on --*-pathspecs options.
There's another use of parse_pathspec(), where pathspec is needed, but
the input is known to be pure paths. In this case we usually don't
want --*-pathspecs to interfere. And we definitely do not want to
parse magic in these paths, regardless of --literal-pathspecs.
Add new flag PATHSPEC_LITERAL_PATH for this purpose. When it's set,
--*-pathspecs are ignored, no magic is parsed. And if the caller
allows PATHSPEC_LITERAL (i.e. the next calls can take literal magic),
then PATHSPEC_LITERAL will be set.
This fixes cases where git chokes when GIT_*_PATHSPECS are set because
parse_pathspec() indicates it won't take any magic. But
GIT_*_PATHSPECS add them anyway. These are
export GIT_LITERAL_PATHSPECS=1
git blame -- something
git log --follow something
git log --merge
"git ls-files --with-tree=path" (aka parse_pathspec() in
overlay_tree_on_cache()) is safe because the input is empty, and
producing one pathspec due to PATHSPEC_PREFER_CWD does not take any
magic into account.

There are cases (e.g. when running concurrent fetches in a repo) where
multiple Git processes concurrently attempt to create loose objects
within the same objects/XX/ dir. The creation of the loose object files
is (AFAICS) safe from races, but the creation of the objects/XX/ dir in
which the loose objects reside is unsafe, for example:
Two concurrent fetches - A and B. As part of its fetch, A needs to store
12aaaaa as a loose object. B, on the other hand, needs to store 12bbbbb
as a loose object. The objects/12 directory does not already exist.
Concurrently, both A and B determine that they need to create the
objects/12 directory (because their first call to git_mkstemp_mode()
within create_tmpfile() fails witn ENOENT). One of them - let's say A -
executes the following mkdir() call before the other. This first call
returns success, and A moves on. When B gets around to calling mkdir(),
it fails with EEXIST, because A won the race. The mkdir() error causes B
to return -1 from create_tmpfile(), which propagates all the way,
resulting in the fetch failing with:
error: unable to create temporary file: File exists
fatal: failed to write object
fatal: unpack-objects failed
Although it's hard to add a testcase reproducing this issue, it's easy
to provoke if we insert a sleep after the
if (mkdir(buffer, 0777) || adjust_shared_perm(buffer))
return -1;
block, and then run two concurrent "git fetch"es against the same repo.
The fix is to simply handle mkdir() failing with EEXIST as a success.
If EEXIST is somehow returned for the wrong reasons (because the relevant
objects/XX is not a directory, or is otherwise unsuitable for object
storage), the following call to adjust_shared_perm(), or ultimately the
retried call to git_mkstemp_mode() will fail, and we end up returning
error from create_tmpfile() in any case.
Note that there are still cases where two users with unsuitable umasks
in a shared repo can end up in two races where one user first wins the
mkdir() race to create an objects/XX/ directory, and then the other user
wins the adjust_shared_perms() race to chmod() that directory, but fails
because it is (transiently, until the first users completes its chmod())
unwriteable to the other user. However, (an equivalent of) this race also
exists before this patch, and is made no worse by this patch.
