Commit 01d3a526ad (t0000: check whether the shell supports the "local"
keyword, 2017-10-26) added a test to gather data on whether people run
the test suite with shells that don't support "local".
After almost two years, nobody has complained, and several other uses
have cropped up in test-lib-functions.sh. Let's declare it acceptable to
use.

t1410.3 ("corrupt and checks") fails when run using dash versions
before 0.5.8, with a cryptic message:
mv: cannot stat '.git/objects//e84adb2704cbd49549e52169b4043871e13432': No such file or directory
The function generating that path:
test_oid_to_path () {
echo "${1%${1#??}}/${1#??}"
}
which is supposed to produce a result like
12/3456789....
But a dash bug[*] causes it to instead expand to
/3456789...
The stream of symbols that makes up this function is hard for humans
to follow, too. The complexity mostly comes from the repeated use of
the expression ${1#??} for the basename of the loose object. Use a
variable instead --- nowadays, the dialect of shell used by Git
permits local variables, so this is cheap.
An alternative way to work around [*] is to remove the double-quotes
around test_oid_to_path's return value. That makes the expression
easier for dash to read, but harder for humans. Let's prefer the
rephrasing that's helpful for humans, too.
Noticed by building on Ubuntu trusty, which uses dash 0.5.7.
[*] Fixed by v0.5.8~13 ("[EXPAND] Propagate EXP_QPAT in subevalvar, 2013-08-23).

In order to make this test work with multiple hash algorithms, compute

This test uses several index hashes, which necessarily depend on the
version of the index and the hash algorithm in use. Use test_oid_cache
to provide values for these for both SHA-1 and SHA-256. Also, compute
an object ID and use $EMPTY_BLOB to make the remainder of the tests
independent of the hash algorithm in use.

Update this test to use test_oid_cache to specify the object IDs for
both SHA-1 and SHA-256. Since this test now works with both algorithms,
remove the SHA1 prerequisite.

One assertion of this test checks for a shrinking cache tree. The
initial index contains a cache tree with two directory names but no
object ID, and the second index contains a cache tree with an object ID
but no directory name.
With SHA-1, the second index is smaller than the first, because the
directory information stored takes more than the 20 bytes of an SHA-1
hash, but with SHA-256, the hash is longer, and the test fails the
assertion that the second index is smaller than the first.
To address this issue, increase the length of the subdirectory name to
ensure that the cache tree does indeed shrink in size regardless of the
algorithm in use.

Several parts of this test generate files that have specific hard-coded
object IDs in them. We don't really care about what the object ID in
question is, so we turn them all to zeros.
However, because some of these values are fixed and some are generated,
they can be of different lengths, which causes problems when running
with SHA-256. Furthermore, some assertions in this test use only fixed
object IDs and some use both fixed and generated ones, so converting
only the expected results fixes some tests while breaking others.
Convert both actual and expected object IDs to the all-zeros object ID
of the appropriate length to ensure that the test passes when using
SHA-256.
The astute observer will notice that both tr and sed are used here.
Converting the tr call to a sed y/// command looks logical at first, but
it isn't possible because POSIX doesn't allow escapes in y/// commands
other than "\\" and "\n".

Compute several object ID values instead of hard-coding them, and use
test_oid_to_path to cleanly produce a path for an object.
Note that the bisect code which is tested here remains sensitive to the
hash algorithm in use because it uses the object ID to disambiguate
between two equidistant commits. Fortunately, SHA-1 and SHA-256
disambiguate identically in the cases we care about, so there is no need
to modify the test to accommodate this situation. However, if a further
hash algorithm change occurs, this test may require some restructuring.

This test uses a stub of a very large (64 GB) object to test our
generation of tar archives. In doing so, it uses the object ID of the
object so it can insert it into the database properly. Look up these
values using test_oid. Restructure the test slightly to use
test_oid_in_path.
Since we care about the object, not how it is named in a particular hash
algorithm, rename it to "huge-object", which is shorter and more
descriptive.

Replace several hard-coded full and partial object IDs with variables or
computed values. Create junk data to stuff inside an invalid tree that
can be either 20 or 32 bytes long. Compute a binary all-zeros object ID
instead of hard-coding a 20-byte length.
Additionally, compute various object IDs by using test_oid and
$EMPTY_BLOB so that this test works with multiple hash algorithms.

Instead of parsing object IDs using fixed-length shell patterns, use cut
to extract the first two characters of an object ID in addition to the
test helper for object paths. Update another test to look up an
appropriate object ID fragment from the all-zeros object ID instead of
hardcoding the value.
Although the test for parsing reflogs at BUFSIZ boundaries passes, mark
it with the SHA1 prerequisite, as it doesn't currently usefully test
anything when using a hash longer than 20 bytes.

There are several places in our testsuite where we want to insert a
slash after an object ID to make it into a path we can reference under
.git/objects, and we have various ways of doing so. Add a helper to
provide a standard way of doing this that works for all size hashes.
