The test for "no shallow lines after receiving ACK ready" is very
sensitive to the timestamps of the commits we create. It's looking for
the fetch negotiation to send a "ready", which in turn depends on the
order in which we traverse commits during the negotiation.
It works reliably now because the base commit "7" is created without
test_commit, and thus gets a commit time matching the current system
clock. Whereas the new commits created in this test do use test_commit,
and get the usual test_tick time from 2005. So the fetch into the
"clone" repository results in a commit graph like this (I omitted some
of the "unrelated" commits for clarity; they're all just a sequence of
test_ticks):
$ git log --graph --format='%ct %s %d'
* 1112912953 new (origin/master, origin/HEAD)
* 1594322236 7 (grafted, master)
* 1112912893 unrelated15 (origin/unrelated15, unrelated15)
[...]
* 1112912053 unrelated1 (origin/unrelated1, unrelated1)
* 1112911993 new-too (HEAD -> newnew, tag: new-too)
The important things to see are:
- "7" is way in the future compared to the other commits
- "new-too" in the fetching repo is older than "new" (and its
"unrelated" ancestors) in the shallow repo
If we change our "setup shallow clone" step to use test_tick, too (and
get rid of the dependency on the system clock), then the test will fail.
The resulting graph looks like this:
$ git log --graph --format='%ct %s %d'
* 1112913373 new (origin/master, origin/HEAD)
* 1112912353 7 (grafted, master)
* 1112913313 unrelated15 (origin/unrelated15, unrelated15)
[...]
* 1112912473 unrelated1 (origin/unrelated1, unrelated1)
* 1112912413 new-too (HEAD -> newnew, tag: new-too)
Our "new-too" is still older than "new" and "unrelated", but now "7" is
older than all of them (because it advanced test_tick, which the other
tests built on top of). In the original, we advertised "7" as the first
"have" before anything else, but now "new-too" is more recent. You'd see
the same thing in the unlikely event that the system clock was set
before our test_tick default in 2005.
Let's make the timing requirements more explicit. The important thing is
that the client advertise all of its shared commits first, before
presenting its unique "new-too" commit. We can do that and get rid of
the system clock dependency at the same time by creating all of the
shared commits around time X (using test_tick), and then creating
"new-too" with some time long before X. The resulting graph looks like
this:
$ git log --graph --format='%ct %s %d'
* 1500001380 new (origin/master, origin/HEAD)
* 1500000420 7 (grafted, master)
* 1500001320 unrelated15 (origin/unrelated15, unrelated15)
[...]
* 1500000480 unrelated1 (origin/unrelated1, unrelated1)
* 1400000060 new-too (HEAD -> newnew, tag: new-too)
That also lets us get rid of the hacky test_tick added by f0e802ca20
(t5539: update a flaky test, 2014-07-14). That was clearly dancing
around the same problem, but only addressed the relationship between
commits created in the two subshells (which did use test_tick, but
overlapped because increments of test_tick in subshells are lost). Now
that we're using consistent and well-placed times for both lines of
history, we don't have to care about a one-tick difference between the
two sides.

A few of the perl tests in t9700 ask for the author and committer ident,
and then make sure we get something sensible. For the timestamp portion,
we just match [0-9]+, because the actual value will depend on when the
test is run. However, we do require that the timezone be "+0000". This
works reliably because we set $TZ in test-lib.sh. But in preparation for
changing the default timezone, let's be a bit more flexible. We don't
actually care about the exact value here, just that we were able to get
a sensible output from the perl module's access methods.

The fetch.writeCommitGraph feature makes fetches write out a commit
graph file for the newly downloaded pack on fetch. This improves the
performance of various commands that would perform a revision walk and
eventually ought to be the default for everyone. To prepare for that
future, it's enabled by default for users that set
feature.experimental=true to experience such future defaults.
Alas, for --unshallow fetches from a shallow clone it runs into a
snag: by the time Git has fetched the new objects and is writing a
commit graph, it has performed a revision walk and r->parsed_objects
contains information about the shallow boundary from *before* the
fetch. The commit graph writing code is careful to avoid writing a
commit graph file in shallow repositories, but the new state is not
shallow, and the result is that from that point on, commands like "git
log" make use of a newly written commit graph file representing a
fictional history with the old shallow boundary.
We could fix this by making the commit graph writing code more careful
to avoid writing a commit graph that could have used any grafts or
shallow state, but it is possible that there are other pieces of
mutated state that fetch's commit graph writing code may be relying
on. So disable it in the feature.experimental configuration.
Google developers have been running in this configuration (by setting
fetch.writeCommitGraph=false in the system config) to work around this
bug since it was discovered in April. Once the fix lands, we'll
enable fetch.writeCommitGraph=true again to give it some early testing
before rolling out to a wider audience.
In other words:
- this patch only affects behavior with feature.experimental=true
- it makes feature.experimental match the configuration Google has
been using for the last few months, meaning it would leave users in
a better tested state than without it
- this should improve testing for other features guarded by
feature.experimental, by making feature.experimental safer to use

Since 37b9dcabfc (shallow.c: use '{commit,rollback}_shallow_file',
2020-04-22), Git knows how to reset stat-validity checks for the
$GIT_DIR/shallow file, allowing it to change between a shallow and
non-shallow state in the same process (e.g., in the case of 'git fetch
--unshallow').
However, when $GIT_DIR/shallow changes, Git does not alter or remove any
grafts (nor substituted parents) in memory.
This comes up in a "git fetch --unshallow" with fetch.writeCommitGraph
set to true. Ordinarily in a shallow repository (and before 37b9dcabfc,
even in this case), commit_graph_compatible() would return false,
indicating that the repository should not be used to write a
commit-graphs (since commit-graph files cannot represent a shallow
history). But since 37b9dcabfc, in an --unshallow operation that check
succeeds.
Thus even though the repository isn't shallow any longer (that is, we
have all of the objects), the in-core representation of those objects
still has munged parents at the shallow boundaries. When the
commit-graph write proceeds, we use the incorrect parentage, producing
wrong results.
There are two ways for a user to work around this: either (1) set
'fetch.writeCommitGraph' to 'false', or (2) drop the commit-graph after
unshallowing.
One way to fix this would be to reset the parsed object pool entirely
(flushing the cache and thus preventing subsequent reads from modifying
their parents) after unshallowing. That would produce a problem when
callers have a now-stale reference to the old pool, and so this patch
implements a different approach. Instead, attach a new bit to the pool,
'substituted_parent', which indicates if the repository *ever* stored a
commit which had its parents modified (i.e., the shallow boundary
prior to unshallowing).
This bit needs to be sticky because all reads subsequent to modifying a
commit's parents are unreliable when unshallowing. Modify the check in
'commit_graph_compatible' to take this bit into account, and correctly
avoid generating commit-graphs in this case, thus solving the bug.

In symdiff_prepare(), we iterate over the set of parsed objects to pick
out any symmetric differences, including the left, right, and base
elements. We assign the results into pointers in a "struct symdiff", and
then complain if we didn't find a base, like so:
sym->left = rev->pending.objects[lpos].name;
sym->right = rev->pending.objects[rpos].name;
sym->base = rev->pending.objects[basepos].name;
if (basecount == 0)
die(_("%s...%s: no merge base"), sym->left, sym->right);
But the least lines are backwards. If basecount is 0, then basepos will
be -1, and we will access memory outside of the pending array. This
isn't usually that big a deal, since we don't do anything besides a
single pointer-sized read before exiting anyway, but it does violate the
C standard, and of course memory-checking tools like ASan complain.
Let's put the basecount check first. Note that we haveto split it from
the other assignments, since the die() relies on sym->left and
sym->right having been assigned (this isn't strictly necessary, but is
easier to read than dereferencing the pending array again).

The first two commits created in t6000 are done without test_tick,
meaning they use the current system clock. After that, we create one
with test_tick, which means it uses a deterministic time in the past.
The result of the "symleft flag bit is propagated down from tag" test
relies on the output order of commits from git-log, which in turn
depends on these timestamps. So this test is technically dependent on
the system clock time, though in practice it would only matter if your
system clock was set before test_tick's default time (which is in 2005).
However, let's use test_tick consistently for those early commits (and
update the expected output to match). This makes the test deterministic,
which is in turn easier to reason about and debug.
Note that there's also a fourth commit here, and it does not use
test_tick. It does have a deterministic timestamp because of the prior
use of test_tick in the script, but it will always be the same time as
the third commit. Let's use test_tick here, too, for consistency. The
matching timestamps between the third and fourth commit are not an
important part of the test.
We could also use test_commit in all of these cases, as it runs
test_tick under the hood. But it would be awkward to do so, as these
tests diverge from the usual test_commit patterns (e.g., by creating
multiple files in a single commit).

In previous commits, we removed the usage of test_must_fail() for most
commands except for a set of pre-approved commands. Since that's done,
only allow test_must_fail() to run those pre-approved commands.
Obviously, we should allow `git`.
We allow `__git*` as some completion functions return an error code that
comes from a git invocation. It's good to avoid using test_must_fail
unnecessarily but it wouldn't hurt to err on the side of caution when
we're potentially wrapping a git command (like in these cases).
We also allow `test-tool` and `test-svn-fe` because these are helper
commands that are written by us and we want to catch their failure.
Finally, we allow `test_terminal` because `test_terminal` just wraps
around git commands. Also, we cannot rewrite
`test_must_fail test_terminal` as `test_terminal test_must_fail` because
test_must_fail() is a shell function and as a result, it cannot be
invoked from the test-terminal Perl script.
We opted to explicitly list the above tools instead of using a catch-all
such as `test[-_]*` because we want to be as restrictive as possible so
that in the future, someone would not accidentally introduce an
unrelated usage of test_must_fail() on an "unapproved" command.

When we are running an alias to an external command, we want to wait for
that process to exit even after receiving ^C which normally kills the
git process. This is useful when the process is ignoring SIGINT (which
e.g. pagers often do), and then we don't want it to be killed.
Having an alias which invokes a pager is probably not common, but it can
be useful e.g. if you have an alias to a git command which uses a
subshell as one of the arguments (in which case you have to use an
external command, not an alias to a builtin).
This patch is similar to the previous commit, but the previous commit
fixed this only for aliases to builtins, while this commit does the same
for aliases to external commands. In addition to waiting after clean
like the previous commit, this also enables cleaning the child (that was
already enabled for aliases to builtins before the previous commit),
because wait_after_clean relies on it. Lastly, while the previous commit

caused the pager to exit. This fixes that for aliases to builtins.
