Dangling symrefs aren't actually a corruption problem. It's perfectly
fine for refs/remotes/origin/HEAD to point to an unborn branch. And in
particular, if you are trying to establish reachability, a symref that
points nowhere doesn't matter either way. Any ref it could point to will
be examined during the rest of the traversal.
It's possible that a symref pointing nowhere _could_ be a sign that the
ref it was meant to point to was deleted accidentally (e.g., via
corruption). But there is no particular reason to think that is true for
any given case, and in the meantime, GIT_REF_PARANOIA kicking in
automatically for some operations means they'll fail unnecessarily.
So let's loosen it just a bit. The new test in t5312 shows off an
example that is safe, but currently fails (and no longer does after this
patch).
Note that we don't do anything if the caller explicitly asked for
DO_FOR_EACH_INCLUDE_BROKEN. In that case they may be looking for
dangling symrefs themselves, and setting GIT_REF_PARANOIA should not
_loosen_ things from what the caller asked for.

When the DO_FOR_EACH_INCLUDE_BROKEN flag is used, we include both actual
corrupt refs (illegal names, missing objects), but also symrefs that
point to nothing. This latter is not really a corruption, but just
something that may happen normally. For example, the symref at
refs/remotes/origin/HEAD may point to a tracking branch which is later
deleted. (The local HEAD may also be unborn, of course, but we do not
access it through ref iteration).
Most callers of for_each_ref() etc, do not care. They don't pass
INCLUDE_BROKEN, so don't see it at all. But for those which do pass it,
this somewhat-normal state causes extra warnings (e.g., from
for-each-ref) or even aborts operations (destructive repacks with
GIT_REF_PARANOIA set).
This patch just introduces the flag and the mechanism; there are no
callers yet (and hence no tests). Two things to note on the
implementation:
- we actually skip any symref that does not resolve to a ref. This
includes ones which point to an invalidly-named ref. You could argue
this is a more serious breakage than simple dangling. But the
overall effect is the same (we could not follow the symref), as well
as the impact on things like REF_PARANOIA (either way, a symref we
can't follow won't impact reachability, because we'll see the ref
itself during iteration). The underlying resolution function doesn't
distinguish these two cases (they both get REF_ISBROKEN).
- we change the iterator in refs/files-backend.c where we check
INCLUDE_BROKEN. There's a matching spot in refs/packed-backend.c,
but we don't know need to do anything there. The packed backend does
not support symrefs at all.
The resulting set of flags might be a bit easier to follow if we broke
this down into "INCLUDE_CORRUPT_REFS" and "INCLUDE_DANGLING_SYMREFS".
But there are a few reasons not do so:
- adding a new OMIT_DANGLING_SYMREFS flag lets us leave existing
callers intact, without changing their behavior (and some of them
really do want to see the dangling symrefs; e.g., t5505 has a test
which expects us to report when a symref becomes dangling)
- they're not actually independent. You cannot say "include dangling
symrefs" without also including refs whose objects are not
reachable, because dangling symrefs by definition do not have an
object. We could tweak the implementation to distinguish this, but
in practice nobody wants to ask for that. Adding the OMIT flag keeps
the implementation simple and makes sure we don't regress the
current behavior.

The documentation for the DO_FOR_EACH_* flags is sprinkled over the

describe them in more detail far away from there, in the definitions of
refs_ref_iterator_begin() and ref_iterator_advance_fn().
Let's try to organize this a bit better:
- convert the #defines to an enum. This makes it clear that they are
related, and that the enum shows the complete set of flags.
- combine all descriptions for each flag in a single spot, next to the
flag's definition
- use the enum rather than a bare int for functions which take the

When repacking or pruning in a corrupted repository, our tests in t5312
argue that it is OK to complete the operation or bail, as long as we
don't actually delete the objects pointed to by the corruption.
This isn't a wrong line of reasoning, but the tests are a bit permissive
by using test_might_fail. The fact is that we _do_ bail currently, and
if we ever stopped doing so, that would be worthy of a human
investigating. So let's switch these to test_must_fail.

In t5312, we create a state with a broken ref, and then make sure that
destructive repacks don't silently ignore the breakage (where a
destructive repack is one that might drop objects). But we don't check
the behavior of non-destructive repacks at all (i.e., ones where we'd
keep unreachable objects).
So let's add a test to confirm the current behavior, which is that
they are allowed (i.e., ignoring the breakage and considering any
objects it points to as unreachable). This may change in the future, but
we'd like for the test suite to alert us to that fact.

Some tests in t5312 create an illegally-named ref, and then see how
various operations handle it. But between those operations, we also do
some more setup (e.g., repacking), and we are subtly depending on how
those setup steps react to the illegal ref.
To future-proof us against those behaviors changing, let's instead
create and clean up our bogus ref on demand in the tests that need it.
This has two small extra advantages:
- the tests are more stand-alone; we do not need an extra test to clean
up the ref before moving on to other parts of the script
- the creation and cleanup is together in one helper function. Because
these depend on touching the refs in the filesystem directly, they
may need to be tweaked for a world with alternate backends (they have
not been noticed so far in the reftable work because with a non-file
backend the tests don't fail; they simply become uninteresting noops
because the broken ref isn't read at all).

When checking how git-clone behaves when it fails, we stimulate some
failures by trying to do a clone from a local repository whose objects
have been removed. Because these clones use local optimizations, there's
a subtle dependency in how the corruption is handled on the sending
side.
If upload-pack does not show us the broken refs (which it does not
currently), then we see only HEAD (which is itself broken), and clone
that as a detached HEAD. When we try to write the ref, we notice that we
never got the object and bail.
But if upload-pack _does_ show us the broken refs (which it may in a
future patch), then we'll realize that HEAD is a symref and just write
that. You'd think we'd fail when writing out the refs themselves, but we
don't; we do a bulk write and skip the connectivity check because of our
--local optimizations. For the non-bare case, we do notice the problem
when we try to checkout. But for a bare repository, we unexpectedly
complete the clone successfully!
At first glance this may seem like a bug. But the whole point of those
local optimizations is to give up some safety for speed. If you want to
be careful, you should be using "--no-local", which would notice that
the pack did not transfer sufficient objects. We could do that in these
tests, but part of the point is for them to fail at specific moments
(and indeed, we have a later test that checks for transport failure).
However, we can make this less subtle and future-proof it against
changes on the upload-pack side by just having an explicit detached
HEAD in the corrupted repo. Now we'll fail as expected during the ref
write if any ref _or_ HEAD is corrupt, whether we're --bare or not.

A few tests in t5516 want to assert that we can delete a corrupted ref
whose pointed-to object is missing. They do so by using the "main"
branch, which is also pointed to by HEAD.
This does work, but only because of a subtle assumption about the
implementation. We do not block the deletion because of the invalid ref,
but we _also_ do not notice that the deleted branch is pointed to by
HEAD. And so the safety rule of "do not allow HEAD to be deleted in a
non-bare repository" does not kick in, and the test passes.
Let's instead use a non-HEAD branch. That still tests what we care about
here (deleting a corrupt ref), but without implicitly depending on our
failure to notice that we're deleting HEAD. That will future proof the
test against that behavior changing.

parse_feature_value() takes an offset, and uses it to seek past the
point in features_list that we've already seen. However if the feature
being searched for does not specify a value, the offset is not
updated. Therefore if we call parse_feature_value() in a loop on a
value-less feature, we'll keep on parsing the same feature over and over
again. This usually isn't an issue: there's no point in using
next_server_feature_value() to search for repeated instances of the same
capability unless that capability typically specifies a value - but a
broken server could send a response that omits the value for a feature
even when we are expecting a value.
Therefore we add an offset update calculation for the no-value case,
which helps ensure that loops using next_server_feature_value() will
always terminate.
next_server_feature_value(), and the offset calculation, were first
added in 2.28 in 2c6a403d96 (connect: add function to parse multiple

We still have Perl and Python code running its own hooks, but that'll

We could make the find_hook() function die() or BUG() out if the new
known_hook() returned 0, but let's make it return NULL just as it does
when it can't find a hook of a known type. Making it die() is overly
anal, and unlikely to be what we need in catching stupid typos in the

be tolerant of unknown hook names, changes in a later series to make
"git hook run" run arbitrary user-configured hook names will be easier
to implement.

54fd3243da ("rebase -i: reread the todo list if `exec` touched it",
2017-04-26) sought to reread the todo list after running an exec
command only if it had been changed. To accomplish this it checks the
stat data of the todo list after running an exec command to see if it
has changed. Unfortunately there are two problems, firstly the
implementation is buggy we actually reread the list after each exec
which is quadratic in the number of commit lookups and secondly the
design is predicated on using nanosecond time stamps which are not the
default.
The implementation bug stems from the fact that we write a new todo
list to disk before running each command but do not update the stat
data to reflect this[1].
The design problem is that it is possible for the user to edit the
todo list without changing its size or inode which means we have to
rely on the mtime to tell us if it has changed. Unfortunately unless
git is built with USE_NSEC it is possible for the original and edited
list to share the same mtime.
Ideally "git rebase --edit-todo" would set a flag that we would then
check in sequencer.c. Unfortunately this is approach will not work as
there are scripts in the wild that write to the todo list directly
without running "git rebase --edit-todo". Instead of relying on stat
data this patch simply reads the possibly edited todo list and
compares it to the original with memcmp(). This is much faster than
reparsing the todo list each time. This patch reduces the time to run
git rebase -r -xtrue v2.32.0~100 v2.32.0
which runs 419 exec commands by 6.6%. For comparison fixing the
implementation bug in stat based approach reduces the time by a
further 1.4% and is indistinguishable from never rereading the todo
list.

2019-11-10) the "git bundle" command was refactored to use
parse_options(). In that refactoring it started understanding the
"--verbose" flag before the subcommand, e.g.:
git bundle --verbose verify --quiet
However, nothing ever did anything with this "verbose" variable, and
the change wasn't documented. It appears to have been something that
escaped the lab, and wasn't flagged by reviewers at the time. Let's
just remove it.
