But as we saw in 4605a73073 ("t1091: don't grep for `strerror()`

`strerror()` yields a slightly different string than the one we're
grepping for. In particular, these tests fail on the NonStop platform.
Similar to 4605a73073, grep for the beginning of the string instead to
avoid relying on `strerror()` behavior.

repository: allow repository format upgrade with extensions
Revert "check_repository_format_gently(): refuse extensions for old repositories"
When upload-pack receives a request containing "have" hashes, it (among
other things) checks if the served repository has the corresponding
objects. However, it does not do so with the
OBJECT_INFO_SKIP_FETCH_OBJECT flag, so if serving a partial clone, a
lazy fetch will be triggered first.
This was discovered at $DAYJOB when a user fetched from a partial clone
(into another partial clone - although this would also happen if the
repo to be fetched into is not a partial clone).
Therefore, whenever "have" hashes are checked for existence, pass the
OBJECT_INFO_SKIP_FETCH_OBJECT flag. Also add the OBJECT_INFO_QUICK flag
to improve performance, as it is typical that such objects do not exist
in the serving repo, and the consequences of a false negative are minor
(usually, a slightly larger pack sent).

We made the mistake in the past of respecting extensions.* even when the
repository format version was set to 0. This is bad because forgetting
to bump the repository version means that older versions of Git (which
do not know about our extensions) won't complain. I.e., it's not a
problem in itself, but it means your repository is in a state which does
not give you the protection you think you're getting from older
versions.
For compatibility reasons, we are stuck with that decision for existing
extensions. However, we'd prefer not to extend the damage further. We
can do that by catching any newly-added extensions and complaining about
the repository format.
Note that this is a pretty heavy hammer: we'll refuse to work with the
repository at all. A lesser option would be to ignore (possibly with a
warning) any new extensions. But because of the way the extensions are
handled, that puts the burden on each new extension that is added to
remember to "undo" itself (because they are handled before we know
for sure whether we are in a v1 repo or not, since we don't insist on a
particular ordering of config entries).
So one option would be to rewrite that handling to record any new
extensions (and their values) during the config parse, and then only
after proceed to handle new ones only if we're in a v1 repository. But
I'm not sure if it's worth the trouble:
- ignoring extensions is likely to end up with broken results anyway
(e.g., ignoring a proposed objectformat extension means parsing any
object data is likely to encounter errors)
- this is a sign that whatever tool wrote the extension field is
broken. We may be better off notifying immediately and forcefully so
that such tools don't even appear to work accidentally.
The only downside is that fixing the situation is a little tricky,
because programs like "git config" won't want to work with the
repository. But:
git config --file=.git/config core.repositoryformatversion 1
should still suffice.

Now that we officially permit repository extensions in repository
format v0, permit upgrading a repository with extensions from v0 to v1
as well.
For example, this means a repository where the user has set
"extensions.preciousObjects" can use "git fetch --filter=blob:none
origin" to upgrade the repository to use v1 and the partial clone
extension.
To avoid mistakes, continue to forbid repository format upgrades in v0
repositories with an unrecognized extension. This way, a v0 user
using a misspelled extension field gets a chance to correct the
mistake before updating to the less forgiving v1 format.
While we're here, make the error message for failure to upgrade the
repository format a bit shorter, and present it as an error, not a
warning.

This reverts commit 14c7fa269e.
The core.repositoryFormatVersion field was introduced in ab9cb76f66
(Repository format version check., 2005-11-25), providing a welcome
bit of forward compatibility, thanks to some welcome analysis by
Martin Atukunda. The semantics are simple: a repository with
core.repositoryFormatVersion set to 0 should be comprehensible by all
Git implementations in active use; and Git implementations should
error out early instead of trying to act on Git repositories with
higher core.repositoryFormatVersion values representing new formats
that they do not understand.
A new repository format did not need to be defined until 00a09d57eb
(introduce "extensions" form of core.repositoryformatversion,
2015-06-23). This provided a finer-grained extension mechanism for
Git repositories. In a repository with core.repositoryFormatVersion
set to 1, Git implementations can act on "extensions.*" settings that
modify how a repository is interpreted. In repository format version
1, unrecognized extensions settings cause Git to error out.
What happens if a user sets an extension setting but forgets to
increase the repository format version to 1? The extension settings
were still recognized in that case; worse, unrecognized extensions
settings do *not* cause Git to error out. So combining repository
format version 0 with extensions settings produces in some sense the
worst of both worlds.
To improve that situation, since 14c7fa269e
(check_repository_format_gently(): refuse extensions for old
repositories, 2020-06-05) Git instead ignores extensions in v0 mode.
This way, v0 repositories get the historical (pre-2015) behavior and
maintain compatibility with Git implementations that do not know about
the v1 format. Unfortunately, users had been using this sort of
configuration and this behavior change came to many as a surprise:
- users of "git config --worktree" that had followed its advice
to enable extensions.worktreeConfig (without also increasing the
repository format version) would find their worktree configuration
no longer taking effect
- tools such as copybara[*] that had set extensions.partialClone in
existing repositories (without also increasing the repository format
version) would find that setting no longer taking effect
The behavior introduced in 14c7fa269e might be a good behavior if we
were traveling back in time to 2015, but we're far too late. For some
reason I thought that it was what had been originally implemented and
that it had regressed. Apologies for not doing my research when
14c7fa269e was under development.
Let's return to the behavior we've had since 2015: always act on
extensions.* settings, regardless of repository format version. While
we're here, include some tests to describe the effect on the "upgrade
repository version" code path.

An earlier "fix" to this script gave up updating it not to rely on
the current time because we cannot control what timestamp subversion
gives its commits. We however could solve the issue in a different
way and still use deterministic timestamps on Git commits.
One fix would be to sort the list of trees before removing duplicates,
but that loses information:
- we do care that the fetched history is in the same order
- there's a tree which appears twice in the history, and we'd want to
make sure that it's there both times
So instead, let's de-duplicate using a hash (preserving the order), and
drop only lines with identical trees and subjects (preserving the tree
which appears twice, since it has different subjects each time).

We always set the name and email for committer and author idents to make
the test suite more deterministic, but not timestamps. Many scripts use
test_tick to get consistent and sensibly incrementing timestamps as they
create commits. But other scripts don't particularly care about the
timestamp, and are happy to use whatever the current system time is.
This non-determinism can be annoying:
- when debugging a test, comparing results between two runs can be
difficult, because the commit ids change
- this can sometimes cause tests to be racy. E.g., traversal order
depends on timestamp order. Even in a well-ordered set of commands,
because our timestamp granularity is one second, two commits might
sometimes have the same timestamp and sometimes differ.
Let's set a default timestamp for all scripts to use. Any that use
test_tick already will be unaffected (because their first test_tick call
will overwrite our default), but it will make things a bit more
deterministic for those that don't.
We should be able to choose any time we want here. I picked this one
because:
- it differs from the initial test_tick default, which may make it
easier to distinguish when debugging tests. I picked "April 1st
13:14:15" in the hope that it might stand out.
- it's slightly before the test_tick default. Some tests create some
commits before the first call to test_tick, so using an older
timestamps for those makes sense chronologically. Note that this
isn't how things currently work (where system times are usually more
recent than test_tick), but that also allows us to flush out a few
hidden timestamp dependencies (like the one recently fixed in
t5539).
- we could likewise pick any timezone we want. Choosing +0000 would
have required fixing up fewer tests, but we're more likely to turn
up interesting cases by not matching $TZ exactly. And since
test_tick already checks "-0700", let's try something in the "+"
zone range for variety.
It's possible that the non-deterministic times could help flush out bugs
(e.g., if something broke when the clock flipped over to 2021, our test
suite would let us know). But historically that hasn't been the case;
all time-dependent outcomes we've seen turned out to be accidentally
flaky tests (which we fixed by using test_tick). If we do want to cover
handling the current time, we should dedicate one script to doing so,
and have it unset GIT_COMMITTER_DATE explicitly.

The early part of t9100 creates an unusual "doubled" history in the
"git-svn" ref. When we get to t9100.17, it looks like this:
$ git log --oneline --graph git-svn
[...]
* efd0303 detect node change from file to directory #2
|\
* | 3e727c0 detect node change from file to directory #2
|/
* 3b00468 try a deep --rmdir with a commit
|\
* | b4832d8 try a deep --rmdir with a commit
|/
* f0d7bd5 import for git svn
Each commit we make with "git commit" is paired with one from "git svn
set-tree", with the latter as a merge of the first and its grandparent.
Later, t9100.17 wants to check that "git svn fetch" gets the same trees.
And it does, but just one copy of each. So it uses rev-list to get the
tree of each commit and pipes it to "uniq" to drop the duplicates. Our
input isn't sorted, but it will find adjacent duplicates. This works
reliably because the order of commits from rev-list always shows the
duplicates next to each other. For any one of those merges, we could
choose to show its duplicate or the grandparent first. But barring
clocks running backwards, the duplicate will always have a time equal to
or greater than the grandparent. Even if equal, we break ties by showing
the first-parent first, so the duplicates remain adjacent.
But this would break if the timestamps stopped moving in chronological
order. Normally we would rely on test_tick for this, but we have _two_
sources of time here:
- "git commit" creates one commit based on GIT_COMMITTER_DATE (which
respects test_tick)
- the "svn set-tree" one is based on subversion, which does not have
an easy way to specify a timestamp
So using test_tick actually breaks the test, because now the duplicates
are far in the past, and we'll show the grandparent before the
duplicate. And likewise, a proposed change to set GIT_COMMITTER_DATE in
all scripts will break it.
We _could_ fix this by sorting before removing duplicates, but
presumably it's a useful part of the test to make sure the trees appear
in the same order in both spots. Likewise, we could use something like:
perl -ne 'print unless $seen{$_}++'
to remove duplicates without impacting the order. But that doesn't work
either, because there are actually multiple (non-duplicate) commits with
the same trees (we change a file mode and then change it back). So we'd
actually have to de-duplicate the combination of subject and tree. Which
then further throws off t9100.18, which compares the tree hashes
exactly; we'd have to strip the result back down.
Since this test _isn't_ buggy, the simplest thing is to just work around
the proposed change by documenting our expectation that git-created
commits are correctly interleaved using the current time.

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.

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.

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.

The test_must_fail() family of functions (including test_might_fail())
should only be used on git commands. Replace test_might_fail() with
a compound command wrapping the old p4 invocation that always returns 0.

We had a `test_must_fail verify_expect`. However, the git command in
verify_expect() was not expected to fail; the test_cmp() was the failing
command. Be more precise about testing failure by accepting an optional
first argument of '!' which causes the result of the file comparison to
be negated.

In the future, we plan on only allowing `test_might_fail` to work on a
restricted subset of commands, including `git`. Reorder the commands so
that `run_with_limited_open_files` comes before `test_might_fail`. This
way, `test_might_fail` operates on a git command.

In a future patch, we plan on making the test_must_fail()-family of
functions accept only git commands. Even though force_color() wraps an
invocation of `env git`, test_must_fail() will not be able to figure
this out since it will assume that force_color() is just some random
function which is disallowed.
Instead of using `env` in force_color() (which does not support shell
functions), export the environment variables in a subshell. Write the
invocation as `force_color test_must_fail git ...` since shell functions
are now supported.

In https://github.com/git-for-windows/git/issues/2677, a `git difftool
-d` problem was reported. The underlying cause was a bug in `git
diff-files --raw` that we just fixed: it reported intent-to-add files
with the empty _tree_ as the post-image OID, when we need to show
an all-zero (or, "null") OID instead, to indicate to the caller that
they have to look at the worktree file.
The symptom of that problem shown by `git difftool` was this:
error: unable to read sha1 file of <path> (<empty-tree-OID>)
error: could not write '<filename>'
Make sure that the reported `difftool` problem stays fixed.

The documented behavior of `git diff-files --raw` is to display
[...] 0{40} if creation, unmerged or "look at work tree".
on the right hand (i.e. postimage) side. This happens for files that
have unstaged modifications, and for files that are unmodified but
stat-dirty.
For intent-to-add files, we used to show the empty blob's hash instead.
In c26022ea8f (diff: convert diff_addremove to struct object_id,
2017-05-30), we made that worse by inadvertently changing that to the
hash of the empty tree.
Let's make the behavior consistent with files that have unstaged
modifications (which applies to intent-to-add files, too) by showing
all-zero values also for intent-to-add files.
Accordingly, this patch adjusts the expectations set by the regression
test introduced in feea6946a5 (diff-files: treat "i-t-a" files as
"not-in-index", 2020-06-20).

git send-email --in-reply-to= fails to override In-Reply-To email headers,
if they're present in the output of format-patch, even when explicitly
told to do so by the option --no-thread, which breaks the contract of the
command line switch option, per its man page.
"

Make the first mail (or all the mails with --no-thread) appear as
