brian m. carlson 06d18bdf86 t1304: abstract away SHA-1-specific constants
Adjust the test so that it uses the $EMPTY_BLOB value instead of
hard-coding the hash.

  not ok 3 - Objects creation does not break ACLs with restrictive umask
  #

  1..4

on systems where USER isn't set.  It's usually set by the login
process, but it isn't set when launching some Docker images.  For
example:

  $ docker run --rm debian env
  HOME=/
  PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
  HOSTNAME=b2dfdfe797ed

'id -u -n' has been in POSIX from Issue 2 through 2013 [1], so I don't
expect compatibility issues.

Jeff King a14ad10911 t1304: improve setfacl prerequisite setup
t1304 first runs setfacl as an experiment to see whether the
filesystem supports ACLs, and skips the remaining tests if
it does not. However, our setfacl run did not exercise the
ACLs very well, and some filesystems may support our initial
setfacl, but not the rest of the test.

In particular, some versions of ecryptfs will erroneously
apply the umask on top of an inherited directory ACL,
causing our tests to fail. Let's be more careful and make
sure both that we can read back the user ACL we set, and
that the inherited ACL is propagated correctly. The latter
catches the ecryptfs bug, but may also catch other bugs
(e.g., an implementation which does not handle inherited
ACLs at all).

Since we're making the setup more complex, let's move it
into its own test. This will hide the output for us unless
the user wants to run "-v" to see it (and we don't need to
bother printing anything about setfacl failing; the
remaining tests will properly print "skip" due to the
missing prerequisite).

Ævar Arnfjörð Bjarmason 063b7e0cd4 t/t1304-default-acl: change from skip_all=* to prereq skip
Change this test to skip test with test prerequisites, and to do setup
work in tests. This improves the skipped statistics on platforms where
the test isn't run.

Ævar Arnfjörð Bjarmason fadb5156e4 tests: Skip tests in a way that makes sense under TAP
SKIP messages are now part of the TAP plan. A TAP harness now knows
why a particular test was skipped and can report that information. The
non-TAP harness built into Git's test-lib did nothing special with
these messages, and is unaffected by these changes.

Brandon Casey 80700fde91 t/t1304: make a second colon optional in the mask ACL check
Solaris only uses one colon in the listing of the ACL mask, Linux uses two,
so substitute egrep for grep and make the second colon optional.

The -q option for Solaris 7's /usr/xpg4/bin/egrep does not appear to be
implemented, so redirect output to /dev/null.

Brandon Casey 2e85575a02 t/t1304: set the ACL effective rights mask
Some implementations of setfacl do not recalculate the effective rights
mask when the ACL is modified.  So, set the effective rights mask
explicitly to ensure that the ACL's that are set on the directories will
have effect.

Brandon Casey 71c4d6c635 t/t1304: use 'test -r' to test readability rather than looking at mode bits
This test was using the group read permission bit as an indicator of the
default ACL mask.  This behavior is valid on Linux but not on other
platforms like Solaris.  So, rather than looking at mode bits, just test
readability for the user.  This, along with the checks for the existence
of the ACL's that were set on the parent directories, should be enough.

Brandon Casey ab04a90567 t/t1304: set the Default ACL base entries
According to the Linux setfacl man page, in order for an ACL to be valid,
the following rules must be satisfied:

   * Whenever an ACL contains any Default ACL entries, the three Default
     ACL base entries (default owner, default group, and default others)
     must also exist.

   * Whenever a Default ACL contains named user entries or named group
     objects, it must also contain a default effective rights mask.

Some implementations of setfacl (Linux) do this automatically when
necessary, some (Solaris) do not.  Solaris's setfacl croaks when trying to
create a default user ACL if the above rules are not satisfied.  So, create
them before modifying the default user ACL's.

Brandon Casey db826571e4 t/t1304: avoid -d option to setfacl
Some platforms (Solaris) have a setfacl whose -d switch works differently
than the one on Linux.  On Linux, it causes all operations to be applied
to the Default ACL.  There is a notation for operating on the Default ACL:

   [d[efault]:] [u[ser]:]uid [:perms]

so use it instead of the -d switch.

Matthieu Moy 5256b00631 Use git_mkstemp_mode instead of plain mkstemp to create object files
We used to unnecessarily give the read permission to group and others,
regardless of the umask, which isn't serious because the objects are
still protected by their containing directory, but isn't necessary
either.

Matthieu Moy f80c7ae8fe Use git_mkstemp_mode and xmkstemp_mode in odb_mkstemp, not chmod later.
We used to create 0600 files, and then use chmod to set the group and
other permission bits to the umask. This usually has the same effect
as a normal file creation with a umask.

But in the presence of ACLs, the group permission plays the role of
the ACL mask: the "g" bits of newly created files are chosen according
to default ACL mask of the directory, not according to the umask, and
doing a chmod() on these "g" bits affect the ACL's mask instead of
actual group permission.

In other words, creating files with 0600 and then doing a chmod to the
umask creates files which are unreadable by users allowed in the
default ACL. To create the files without breaking ACLs, we let the
umask do it's job at the file's creation time, and get rid of the
later chmod.

Matthieu Moy 7aba6185d5 Add a testcase for ACL with restrictive umask.
Right now, Git creates unreadable pack files on non-shared
repositories when the user has a umask of 077, even when the default
ACLs for the directory would give read/write access to a specific
user.

Loose object files are created world-readable, which doesn't break ACLs,
but isn't necessarily desirable.
