t: fix some trivial cases of ignored exit codes in loops
These are all cases where we do a setup step of the form:
for i in $foo; do

would not notice a failure in set_up (because break always
returns a 0 exit code). These are just setup steps that we
do not expect to fail, but it does not hurt to be defensive.
Most can be fixed by converting the "break" to a "return 1"
(since we eval our tests inside a function for just this
purpose). A few of the loops are inside subshells, so we can
use just "exit 1" to break out of the subshell. And a few
can actually be made shorter by just unrolling the loop.

t3305: fix ignored exit code inside loop
When we test deleting notes, we run "git notes remove" in a
loop. However, the exit value of the loop will only reflect
the final note we process. We should break out of the loop
with a failing exit code as soon as we see a problem.
Note that we can call "exit 1" here without explicitly
creating a subshell, because the while loop on the
right-hand side of a pipe executes in its own implicit
subshell.
Note also that the "break" above does not suffer the same
problem; it is meant to exit the loop early at a certain
number of iterations. We can bump it into the conditional of
the loop to make this more obvious.

A loop like:

will correctly break out of the loop when we see a failure

zero. We can fix that by putting the loop into a function or

unroll the loop. We do add a helper function, which
hopefully makes the end result even more readable (in

report_path_error(): move to dir.c
The expected call sequence is for the caller to use match_pathspec()
repeatedly on a set of pathspecs, accumulating the "hits" in a
separate array, and then call this function to diagnose a pathspec
that never matched anything, as that can indicate a typo from the
command line, e.g. "git commit Maekfile".
Many builtin commands use this function from builtin/ls-files.c,
which is not a very healthy arrangement. ls-files might have been
the first command to feel the need for such a helper, but the need
is shared by everybody who uses the "match and then report" pattern.

read-cache: fix memleak
`ce` is allocated in make_cache_entry and should be freed if it is not

will either return
- the `ce` given as the parameter, when it was up-to-date;
- a new updated cache entry which is allocated to new memory; or
- a NULL when refreshing failed.
In the latter two cases, the original cache-entry `ce` is not used

run-command: introduce capture_command helper
Something as simple as reading the stdout from a command
turns out to be rather hard to do right. Doing:
cmd.out = -1;
run_command(&cmd);
strbuf_read(&buf, cmd.out, 0);
can result in deadlock if the child process produces a large
amount of output. What happens is:
1. The parent spawns the child with its stdout connected
to a pipe, of which the parent is the sole reader.
2. The parent calls wait(), blocking until the child exits.
3. The child writes to stdout. If it writes more data than
the OS pipe buffer can hold, the write() call will
block.
This is a deadlock; the parent is waiting for the child to
exit, and the child is waiting for the parent to call
read().
So we might try instead:
start_command(&cmd);
strbuf_read(&buf, cmd.out, 0);
finish_command(&cmd);
But that is not quite right either. We are examining cmd.out
and running finish_command whether start_command succeeded
or not, which is wrong. Moreover, these snippets do not do
any error handling. If our read() fails, we must make sure
to still call finish_command (to reap the child process).
And both snippets failed to close the cmd.out descriptor,
which they must do (provided start_command succeeded).

refs.c: drop curate_packed_refs
When we delete a ref, we have to rewrite the entire
packed-refs file. We take this opportunity to "curate" the
packed-refs file and drop any entries that are crufty or
broken.
Dropping broken entries (e.g., with bogus names, or ones
that point to missing objects) is actively a bad idea, as it
means that we lose any notion that the data was there in the
first place. Aside from the general hackiness that we might
lose any information about ref "foo" while deleting an
unrelated ref "bar", this may seriously hamper any attempts
by the user at recovering from the corruption in "foo".
They will lose the sha1 and name of "foo"; the exact pointer
may still be useful even if they recover missing objects
from a different copy of the repository. But worse, once the
ref is gone, there is no trace of the corruption. A
follow-up "git prune" may delete objects, even though it
would otherwise bail when seeing corruption.
We could just drop the "broken" bits from
curate_packed_refs, and continue to drop the "crufty" bits:
refs whose loose counterpart exists in the filesystem. This
is not wrong to do, and it does have the advantage that we
may write out a slightly smaller packed-refs file. But it
has two disadvantages:
1. It is a potential source of races or mistakes with
respect to these refs that are otherwise unrelated to
the operation. To my knowledge, there aren't any active
problems in this area, but it seems like an unnecessary
risk.
2. We have to spend time looking up the matching loose
refs for every item in the packed-refs file. If you
have a large number of packed refs that do not change,
that outweighs the benefit from writing out a smaller
packed-refs file (it doesn't get smaller, and you do a
bunch of directory traversal to find that out).

t5312: test object deletion code paths in a corrupted repository
When we are doing a destructive operation like "git prune",
we want to be extra careful that the set of reachable tips
we compute is valid. If there is any corruption or oddity,
we are better off aborting the operation and letting the
user figure things out rather than plowing ahead and
possibly deleting some data that cannot be recovered.
The tests here include:
1. Pruning objects mentioned only be refs with invalid
names. This used to abort prior to
d0f810f (refs.c:
allow listing and deleting badly named refs,
2014-09-03), but since then we silently ignore the tip.
Likewise, we test repacking that can drop objects
(either "-ad", which drops anything unreachable,
or "-Ad --unpack-unreachable=<time>", which tries to
optimize out a loose object write that would be
directly pruned).
2. Pruning objects when some refs point to missing
objects. We don't know whether any dangling objects
would have been reachable from the missing objects. We
are better to keep them around, as they are better than
nothing for helping the user recover history.
3. Packed refs that point to missing objects can sometimes
be dropped. By itself, this is more of an annoyance
(you do not have the object anyway; even if you can
recover it from elsewhere, all you are losing is a
placeholder for your state at the time of corruption).
But coupled with (2), if we drop the ref and then go
on to prune, we may lose unrecoverable objects.
Note that we use test_might_fail for some of the operations.
In some cases, it would be appropriate to abort the
operation, and in others, it might be acceptable to continue
but taking the information into account. The tests don't
care either way, and check only for data loss.

Also, looking at what the test intended to test according to
7f578c5 (git-svn: --follow-parent now works on sub-directories of larger
branches, 2007-01-24)
it is not clear how it would achieve that with the given steps.
Amend the test to include the second svn id to be tested for, and
change the tested refs to the ones which are to be expected, and which
make the test pass.
