One-shot environment variable assignments, such as 'FOO' in
"FOO=bar cmd", exist only during the invocation of 'cmd'. However, if
'cmd' happens to be a shell function, then 'FOO' is assigned in the
executing shell itself, and that assignment remains until the process
exits (unless explicitly unset). Since this side-effect of
"FOO=bar shell_func" is unlikely to be intentional, detect and report
such usage.
To distinguish shell functions from other commands, perform a pre-scan
of shell scripts named as input, gleaning a list of function names by
recognizing lines of the form (loosely matching whitespace):
shell_func () {
and later report suspect lines of the form (loosely matching quoted
values):
FOO=bar [BAR=foo ...] shell_func
Also take care to stitch together incomplete lines (those ending with
"\") since suspect invocations may be split over multiple lines:
FOO=bar BAR=foo \
shell_func

Error messages emitted by this linting script are long and noisy,
consisting of several sections:
<test-script>:<line#>: error: <explanation>: <failed-shell-text>
The line of failed shell text, usually coming from within a test body,
is often indented by one or two TABs, with the result that the actual
(important) text is separated from <explanation> by a good deal of empty
space. This can make for a difficult read, especially on typical
80-column terminals.
Make the messages more compact and perhaps a bit easier to digest by
folding out the leading whitespace from <failed-shell-text>.

Unlike "FOO=bar cmd" one-shot environment variable assignments
which exist only for the invocation of 'cmd', those assigned by
"FOO=bar shell_func" exist within the running shell and continue to
do so until the process exits (or are explicitly unset). It is
unlikely that this behavior was intended by the test author.
In these particular tests, the "FOO=bar shell_func" invocations are
already in subshells, so the assignments don't last too long, don't
appear to harm subsequent commands in the same subshells, and don't
affect other tests in the same scripts, however, the usage is
nevertheless misleading and poor practice, so fix the tests to assign
and export the environment variables in the usual fashion.

We added an fsck check in ed8b10f631 (fsck: check
.gitmodules content, 2018-05-02) as a defense against the
vulnerability from 0383bbb901 (submodule-config: verify
submodule names as paths, 2018-04-30). With the idea that
up-to-date hosting sites could protect downstream unpatched
clients that fetch from them.
As part of that defense, we reject any ".gitmodules" entry
that is not syntactically valid. The theory is that if we
cannot even parse the file, we cannot accurately check it
for vulnerabilities. And anybody with a broken .gitmodules
file would eventually want to know anyway.
But there are a few reasons this is a bad tradeoff in
practice:
- for this particular vulnerability, the client has to be
able to parse the file. So you cannot sneak an attack
through using a broken file, assuming the config parsers
for the process running fsck and the eventual victim are
functionally equivalent.
- a broken .gitmodules file is not necessarily a problem.
Our fsck check detects .gitmodules in _any_ tree, not
just at the root. And the presence of a .gitmodules file
does not necessarily mean it will be used; you'd have to
also have gitlinks in the tree. The cgit repository, for
example, has a file named .gitmodules from a
pre-submodule attempt at sharing code, but does not
actually have any gitlinks.
- when the fsck check is used to reject a push, it's often
hard to work around. The pusher may not have full control
over the destination repository (e.g., if it's on a
hosting server, they may need to contact the hosting
site's support). And the broken .gitmodules may be too
far back in history for rewriting to be feasible (again,
this is an issue for cgit).
So we're being unnecessarily restrictive without actually
improving the security in a meaningful way. It would be more
convenient to downgrade this check to "info", which means
we'd still comment on it, but not reject a push. Site admins
can already do this via config, but we should ship sensible
defaults.
There are a few counterpoints to consider in favor of
keeping the check as an error:
- the first point above assumes that the config parsers for
the victim and the fsck process are equivalent. This is
pretty true now, but as time goes on will become less so.
Hosting sites are likely to upgrade their version of Git,
whereas vulnerable clients will be stagnant (if they did
upgrade, they'd cease to be vulnerable!). So in theory we
may see drift over time between what two config parsers
will accept.
In practice, this is probably OK. The config format is
pretty established at this point and shouldn't change a
lot. And the farther we get from the announcement of the
vulnerability, the less interesting this extra layer of
protection becomes. I.e., it was _most_ valuable on day
0, when everybody's client was still vulnerable and
hosting sites could protect people. But as time goes on
and people upgrade, the population of vulnerable clients
becomes smaller and smaller.
- In theory this could protect us from other
vulnerabilities in the future. E.g., .gitmodules are the
only way for a malicious repository to feed data to the
config parser, so this check could similarly protect
clients from a future (to-be-found) bug there.
But that's trading a hypothetical case for real-world
pain today. If we do find such a bug, the hosting site
would need to be updated to fix it, too. At which point
we could figure out whether it's possible to detect
_just_ the malicious case without hurting existing
broken-but-not-evil cases.
- Until recently, we hadn't made any restrictions on
.gitmodules content. So now in tightening that we're
hitting cases where certain things used to work, but
don't anymore. There's some moderate pain now. But as
time goes on, we'll see more (and more varied) cases that
will make tightening harder in the future. So there's
some argument for putting rules in place _now_, before
users grow more cases that violate them.
Again, this is trading pain now for hypothetical benefit
in the future. And if we try hard in the future to keep
our tightening to a minimum (i.e., rejecting true
maliciousness without hurting broken-but-not-evil repos),
then that reduces even the hypothetical benefit.
Considering both sets of arguments, it makes sense to loosen
this check for now.
Note that we have to tweak the test in t7415 since fsck will
no longer consider this a fatal error. But we still check
that it reports the warning, and that we don't get the
spurious error from the config code.

This patch broadens the set of commits matched by ":/<pattern>" to
include commits reachable from HEAD but not any named ref. This avoids
surprising behavior when working with a detached HEAD and trying to
refer to a commit that was recently created and only exists within the
detached state.
If multiple worktrees exist, only the current worktree's HEAD is
considered reachable. This is consistent with the existing behavior for
other per-worktree refs: e.g., bisect refs are considered reachable, but
only within the relevant worktree.

The last test of 't5561-http-backend.sh', 'server request log matches
test results' may fail occasionally, because the order of entries in
Apache's access log doesn't match the order of requests sent in the
previous tests, although all the right requests are there. I saw it
fail on Travis CI five times in the span of about half a year, when
the order of two subsequent requests was flipped, and could trigger
the failure with a modified Git. However, I was unable to trigger it
with stock Git on my machine. Three tests in
't5541-http-push-smart.sh' and 't5551-http-fetch-smart.sh' check
requests in the log the same way, so they might be prone to a similar
occasional failure as well.
When a test sends a HTTP request, it can continue execution after
'git-http-backend' fulfilled that request, but Apache writes the
corresponding access log entry only after 'git-http-backend' exited.
Some time inevitably passes between fulfilling the request and writing
the log entry, and, under unfavourable circumstances, enough time
might pass for the subsequent request to be sent and fulfilled by a
different Apache thread or process, and then Apache writes access log
entries racily.
This effect can be exacerbated by adding a bit of variable delay after
the request is fulfilled but before 'git-http-backend' exits, e.g.
like this:
diff --git a/http-backend.c b/http-backend.c
index f3dc218b2..bbf4c125b 100644
--- a/http-backend.c
+++ b/http-backend.c
@@ -709,5 +709,7 @@ int cmd_main(int argc, const char **argv)
max_request_buffer);
cmd->imp(&hdr, cmd_arg);
+ if (getpid() % 2)
+ sleep(1);
return 0;
}
This delay considerably increases the chances of log entries being
written out of order, and in turn makes t5561's last test fail almost
every time. Alas, it doesn't seem to be enough to trigger a similar
failure in t5541 and t5551.
So, since we can't just rely on the order of access log entries always
corresponding the order of requests, make checking the access log more
deterministic by sorting (simply lexicographically) both the stripped
access log entries and the expected entries before the comparison with
'test_cmp'. This way the order of log entries won't matter and
occasional out-of-order entries won't trigger a test failure, but the
comparison will still notice any unexpected or missing log entries.
OTOH, this sorting will make it harder to identify from which test an
unexpected log entry came from or which test's request went missing.
Therefore, in case of an error include the comparison of the unsorted
log enries in the test output as well.
And since all this should be performed in four tests in three test
scripts, put this into a new helper function 'check_access_log' in
't/lib-httpd.sh'.

In the second test of 't5541-http-push-smart.sh', 'no empty path
components' we truncate Apache's access log by running:
echo >.../access.log
There are two issues with this approach:
- This doesn't leave an empty file behind, like a proper truncation
would, but a file with a lone newline in it. Consequently, a
later test checking the log's contents must consider this improper
truncation and include an empty line in the expected content.
- This truncation is done in the middle of the test, because,
quoting the in-code comment, "we do this [truncation] before the
actual comparison to ensure the log is cleared" even when
subsequent 'test_cmp' fails. Alas, this is not quite robust
enough, as it is conceivable that 'git clone' fails after already
having sent a request, in which case the access log would not be
truncated and would leave stray log entries behind.
Since there is no need for that newline at all, drop the 'echo' from
the truncation and adjust the expected content accordingly.
Furthermore, make sure that the truncation is performed no matter
whether and how 'git clone' fails unexpectedly by specifying it as a
'test_when_finished' command.

If has_uncommitted_changes() can't resolve HEAD (e.g.,
because it's unborn or corrupt), then we end up calling
run_diff_index() with an empty revs.pending array. This
causes a segfault, as run_diff_index() blindly looks at the
first pending item.
Fixing this raises a question of fault: should
run_diff_index() handle this case, or is the caller wrong to
pass an empty pending list?
Looking at the other callers of run_diff_index(), they
handle this in one of three ways:
- they resolve the object themselves, and avoid doing the
diff if it's not valid
- they resolve the object themselves, and fall back to the
empty tree
- they use setup_revisions(), which will die() if the
object isn't valid
Since this is the only broken caller, that argues that the
fix should go there. Falling back to the empty tree makes
sense here, as we'd claim uncommitted changes if and only if
the index is non-empty. This may be a little funny in the
case of corruption (the corrupt HEAD probably _isn't_
empty), but:
- we don't actually know the reason here that HEAD didn't
resolve (the much more likely case is that we have an
unborn HEAD, in which case the empty tree comparison is
the right thing)
- this matches how other code, like "git diff", behaves
While we're thinking about it, let's add an assertion to
run_diff_index(). It should always be passed a single
object, and as this bug shows, it's easy to get it wrong
(and an assertion is easier to hunt down than a segfault, or
a quietly ignored extra tree).

Use the fix suggested in [1]. Also, add test case which verifies the

If the user gives us a set that prepare_revision_walk()
takes to be empty, like:
git cherry-pick base..base
then we report an error. It's nonsense, and there's nothing
to pick.
But if they use revision options that later cull the list,
like:
git cherry-pick --author=nobody base~2..base
then we quietly create an empty todo list and return
success.
Arguably either behavior is acceptable, but we should
definitely be consistent about it. Reporting an error
seems to match the original intent, which dates all the way
back to 7e2bfd3f99 (revert: allow cherry-picking more than
one commit, 2010-06-02). That in turn was trying to match
the single-commit case that existed before then (and which
continues to issue an error).

The commit that introduced the partial clone feature - 548719fbdc
("clone: partial clone", 2017-12-08) - excluded connectivity checks
for partial clones, but this also meant that it is possible for a clone
to succeed, yet not have all objects either present or promised.
Specifically, if cloning with --filter=blob:none from a repository that
has a tag pointing to a blob, and the blob is not sent in the packfile,
the clone will pass, even if the blob is not referenced by any tree in
the packfile.

A filter line in a request to upload-pack filters out objects regardless
of whether they are directly referenced by a "want" line or not. This
means that cloning with "--filter=blob:none" (or another filter that
excludes blobs) from a repository with at least one ref pointing to a
blob (for example, the Git repository itself) results in output like the
following:
error: missing object referenced by 'refs/tags/junio-gpg-pub'
and if that particular blob is not referenced by a fetched tree, the
resulting clone fails fsck because there is no object from the remote to
vouch that the missing object is a promisor object.
Update both the protocol and the upload-pack implementation to include
all explicitly specified "want" objects in the packfile regardless of
the filter specification.

git send-email, when invoked without a --transfer-encoding option, sends
8bit data without a MIME version or a transfer encoding. This has
several downsides.
First, unless the transfer encoding is specified, it defaults to 7bit,
meaning that non-ASCII data isn't allowed. Second, if lines longer than
998 bytes are used, we will send an message that is invalid according to
RFC 5322. The --validate option, which is the default, catches this
issue, but it isn't clear to many people how to resolve this.
To solve these issues, default the transfer encoding to "auto", so that
we explicitly specify 8bit encoding when lines don't exceed 998 bytes
and quoted-printable otherwise. This means that we now always emit
Content-Transfer-Encoding and MIME-Version headers, so remove the
conditionals from this portion of the code.
It is unlikely that the unconditional inclusion of these two headers
will affect the deliverability of messages in anything but a positive

programs.

With --validate (which is the default), we warn about lines exceeding
998 characters due to the limits specified in RFC 5322. However, if
we're using a suitable transfer encoding (quoted-printable or base64),
we're guaranteed not to have lines exceeding 76 characters, so there's
no need to fail in this case. The auto transfer encoding handles this
specific case, so accept it as well.

For most patches, using a transfer encoding of 8bit provides good
compatibility with most servers and makes it as easy as possible to view
patches. However, there are some patches for which 8bit is not a valid
encoding: RFC 5322 specifies that a message must not have lines
exceeding 998 octets.
Add a transfer encoding value, auto, which indicates that a patch should
use 8bit where allowed and quoted-printable otherwise. Choose
quoted-printable instead of base64, since base64-encoded plain text is
treated as suspicious by some spam filters.

A later patch changes the built-in PHP pattern. These test cases
demonstrate aspects of the pattern that we do not want to change.

There was a discussion of problematic directory/file conflicts with
virtual merge bases on the mailing list years ago at
https://public-inbox.org/git/AANLkTimwUQafGDrjxWrfU9uY1uKoFLJhxYs=vssOPqdf@mail.gmail.com/
Part of these corresponding tests made it into this testsuite. However,
the more problematic one didn't. And there are others that showcase the
problems even more. Add a very lengthy explanation, some of it from that
email, describing the tradeoffs in picking a recursive merge-base when
you're dealing with an add/add directory/file conflict.
The solution picked years ago is relatively good, but there is the
potential to do even better, assuming we're willing to pay a certain
performance cost.
