The git-stash(1) command needs to write to the index for many of its
operations. When the index is locked by a concurrent writer it will thus
fail to operate, which is expected. What is not expected though is that
we do not print any error message at all in this case. The user can thus
easily miss the fact that the command didn't do what they expected it to
do and would be left wondering why that is.
Fix this bug and report failures to write to the index. Add tests for
the subcommands which hit the respective code paths.
While at it, unify error messages when writing to the index fails. The
chosen error message is already used in "builtin/stash.c".

Running this:
$ touch foo bar
$ chmod +x foo
$ git -c diff.external=echo diff --ext-diff --no-index foo bar
results in a segfault. The issue is that run_diff_cmd() passes a NULL
"xfrm_msg" variable to run_external_diff(), which feeds it to
strvec_push(), causing the segfault. The bug dates back to 82fbf269b9
(run_external_diff: use an argv_array for the command line, 2014-04-19),
though it mostly only ever worked accidentally. Before then, we just
stuck the NULL pointer into a "const char **" array, so our NULL ended
up acting as an extra end-of-argv sentinel (which was OK, because it was
the last thing in the array).
Curiously, though, this is only a problem with --no-index. We set up
xfrm_msg by calling fill_metainfo(). This result may be empty, or may
have text like "index 1234..5678\n", "rename from foo\nrename from
bar\n", etc. In run_external_diff(), we only look at xfrm_msg if the
"other" variable is not NULL. That variable is set when the paths of the
two sides of the diff pair aren't the same (in which case the
destination path becomes "other"). So normally it would kick in only for
a rename, in which case xfrm_msg should not be NULL (it would have the
rename information in it).
But with a "--no-index" of two blobs, we of course have two different
pathnames, and thus end up with a non-NULL "other" filename (which is
always just a repeat of the file2-name), but possibly a NULL xfrm_msg.
So how to fix it? I have a feeling that --no-index always passing
"other" to the external diff command is probably a bug. There was no
rename, and the name is always redundant with existing information we
pass (and this may even cause us to pass a useless "xfrm_msg" that
contains an "index 1234..5678" line). So one option would be to change
that behavior. We don't seem to have ever documented the "other" or
"xfrm_msg" parameters for external diffs.
But I'm not sure what fallout we might have from changing that behavior
now. So this patch takes the less-risky option, and simply teaches
run_external_diff() to avoid passing xfrm_msg when it's NULL. That makes
it agnostic to whether "other" and "xfrm_msg" always come as a pair. It
fixes the segfault now, and if we want to change the --no-index "other"
behavior on top, it will handle that, too.

hash_chars() would hash lines to integers, and store them in a spanhash,
but cut lines at 64 characters. Thus, whenever it reached 64 characters
or a newline, it would create a new spanhash. The problem is, the final
part of the file might not end 64 characters after the previous 'line'
and might not end with a newline. This could, for example, cause an
85-byte file with 12 lines and only the first character in the file
differing to appear merely 23% similar rather than the expected 97%.
Ensure the last line is included, and add a testcase that would have
caught this problem.

9080a7f178 (builtin/show-ref: add new mode to check for reference

When you use this option against a ref that doesn't exist, but it is
a parent directory of an existing ref, you get the following error:
$ git show-ref --exists refs/heads
error: failed to look up reference: Is a directory
when the ref-files backend is in use. To be more clear to user,
hide the error about having found a directory. What matters to the
user is that the named ref does not exist. Instead, print the same
error as when the ref was not found:

This fixes a regression introduced in ac6d45d11f (commit-graph: move
slab-clearing to close_commit_graph(), 2023-10-03), in which running:
git -c fetch.writeCommitGraph=true fetch --recurse-submodules
multiple times in a freshly cloned repository causes a segfault. What
happens in the second (and subsequent) runs is this:
1. We make a "struct commit" for any ref tips which we're storing
(even if we already have them, they still go into FETCH_HEAD).
Because the first run will have created a commit graph, we'll find
those commits in the graph.
The commit struct is therefore created with a NULL "maybe_tree"
entry, because we can load its oid from the graph later. But to do
that we need to remember that we got the commit from the graph,
which is recorded in a global commit_graph_data_slab object.
2. Because we're using --recurse-submodules, we'll try to fetch each
of the possible submodules. That implies creating a separate
"struct repository" in-process for each submodule, which will
require a later call to repo_clear().
The call to repo_clear() calls raw_object_store_clear(), which in
turn calls close_object_store(), which in turn calls
close_commit_graph(). And the latter frees the commit graph data
slab.
3. Later, when trying to write out a new commit graph, we'll ask for
their tree oid via get_commit_tree_oid(), which will see that the
object is parsed but with a NULL maybe_tree field. We'd then
usually pull it from the graph file, but because the slab was
cleared, we don't realize that we can do so! We end up returning
NULL and segfaulting.
(It seems questionable that we'd write a graph entry for such a
commit anyway, since we know we already have one. I didn't
double-check, but that may simply be another side effect of having
cleared the slab).
The bug is in step (2) above. We should not be clearing the slab when
cleaning up the submodule repository structs. Prior to ac6d45d11f, we
did not do so because it was done inside a helper function that returned
early when it saw NULL. So the behavior change from that commit is that
we'll now _always_ clear the slab via repo_clear(), even if the
repository being closed did not have a commit graph (and thus would have
a NULL commit_graph struct).
The most immediate fix is to add in a NULL check in close_commit_graph(),
making it a true noop when passed in an object_store with a NULL
commit_graph (it's OK to just return early, since the rest of its code
is already a noop when passed NULL). That restores the pre-ac6d45d11f
behavior. And that's what this patch does, along with a test that
exercises it (we already have a test that uses submodules along with
fetch.writeCommitGraph, but the bug only triggers when there is a
subsequent fetch and when that fetch uses --recurse-submodules).
So that fixes the regression in the least-risky way possible.
I do think there's some fragility here that we might want to follow up
on. We have a global commit_graph_data_slab that contains graph
positions, and our global commit structs depend on the that slab
remaining valid. But close_commit_graph() is just about closing _one_
object store's graph. So it's dangerous to call that function and clear
the slab without also throwing away any "struct commit" we might have
parsed that depends on it.
Which at first glance seems like a bug we could already trigger. In the
situation described here, there is no commit graph in the submodule
repository, so our commit graph is NULL (in fact, in our test script
there is no submodule repo at all, so we immediately return from
repo_init() and call repo_clear() only to free up memory). But what
would happen if there was one? Wouldn't we see a non-NULL commit_graph
entry, and then clear the global slab anyway?
The answer is "no", but for very bizarre reasons. Remember that
repo_clear() calls raw_object_store_clear(), which then calls
close_object_store() and thus close_commit_graph(). But before it does
so, raw_object_store_clear() does something else: it frees the commit
graph and sets it to NULL! So by this code path we'll _never_ see a
non-NULL commit_graph struct, and thus never clear the slab.
So it happens to work out. But it still seems questionable to me that we
would clear a global slab (which might still be in use) when closing the
commit graph. This clearing comes from 957ba814bf (commit-graph: when
closing the graph, also release the slab, 2021-09-08), and was fixing a
case where we really did need it to be closed (and in that case we
presumably call close_object_store() more directly).
So I suspect there may still be a bug waiting to happen there, as any
object loaded before the call to close_object_store() may be stranded
with a bogus maybe_tree entry (and thus looking at it after the call
might cause an error). But I'm not sure how to trigger it, nor what the
fix should look like (you probably would need to "unparse" any objects
pulled from the graph). And so this patch punts on that for now in favor
of fixing the recent regression in the most direct way, which should not
have any other fallouts.

To compute the expected on-disk size of packed objects, we sort the
output of show-index by pack offset and then compute the difference
between adjacent entries using awk. This works but has a few readability
problems:
1. Reading the index in pack order means don't find out the size of an
oid's entry until we see the _next_ entry. So we have to save it to
print later.
We can instead iterate in reverse order, so we compute each oid's
size as we see it.
2. Since the awk invocation is inside a text_expect block, we can't
easily use single-quotes to hold the script. So we use
double-quotes, but then have to escape the dollar signs in the awk
script.
We can swap this out for a shell loop instead (which is made much
easier by the first change).

Back when we added this placeholder in a4ac106178 (cat-file: add
%(objectsize:disk) format atom, 2013-07-10), there were no tests,
claiming "[...]the exact numbers returned are volatile and subject to
zlib and packing decisions".
But we can use a little shell hackery to get the expected numbers
ourselves. To a certain degree this is just re-implementing what Git is
doing under the hood, but it is still worth doing. It makes sure we
exercise the %(objectsize:disk) code at all, and having the two
implementations agree gives us more confidence.
Note that our shell code assumes that no object appears twice (either in
two packs, or as both loose and packed), as then the results really are
undefined. That's OK for our purposes, and the test will notice if that
assumption is violated (the shell version would produce duplicate lines
that Git's output does not have).

When calling "packet_read_with_status()" to parse pkt-line encoded
packets, we can turn on the flag "PACKET_READ_CHOMP_NEWLINE" to chomp
newline character for each packet for better line matching. But when
receiving data and progress information using sideband, we should turn
off the flag "PACKET_READ_CHOMP_NEWLINE" to prevent mangling newline
characters from data and progress information.
When both the server and the client support "sideband-all" capability,
we have a dilemma that newline characters in negotiation packets should
be removed, but the newline characters in the progress information
should be left intact.
Add new flag "PACKET_READ_USE_SIDEBAND" for "packet_read_with_status()"
to prevent mangling newline characters in sideband messages.

When we turn on the "use_sideband" field of the packet_reader,
"packet_reader_read()" will call the function "demultiplex_sideband()"
to parse and consume sideband messages. Sideband fragment which does not
end with "\r" or "\n" will be saved in the sixth parameter "scratch"
and it can be reused and be concatenated when parsing another sideband
message.
In "packet_reader_read()" function, the local variable "scratch" can
only be reused by subsequent sideband messages. But if there is a
payload message between two sideband fragments, the first fragment
which is saved in the local variable "scratch" will be lost.
To solve this problem, we can add a new field "scratch" in
packet_reader to memorize the sideband fragment across different calls
of "packet_reader_read()".

We can use the test helper program "test-tool pkt-line" to test pkt-line
related functions. E.g.:
* Use "test-tool pkt-line send-split-sideband" to generate sideband
messages.
* Pipe these generated sideband messages to command "test-tool pkt-line
unpack-sideband" to test packet_reader_read() function.
In order to make a complete test of the packet_reader_read() function,
add option parser for command "test-tool pkt-line unpack-sideband".
* To remove newlines in sideband messages, we can use:
$ test-tool pkt-line unpack-sideband --chomp-newline
* To preserve newlines in sideband messages, we can use:
$ test-tool pkt-line unpack-sideband --no-chomp-newline
* To parse sideband messages using "demultiplex_sideband()" inside the
function "packet_reader_read()", we can use:
$ test-tool pkt-line unpack-sideband --reader-use-sideband
We also add new example sideband packets in send_split_sideband() and
add several new test cases in t0070. Among these test cases, we pipe
output of the "send-split-sideband" subcommand to the "unpack-sideband"
subcommand. We found two issues:
1. The two splitted sideband messages "Hello," and " world!\n" should
be concatenated together. But when we turn on use_sideband field of
reader to parse sideband messages, the first part of the splitted
message ("Hello,") is lost.
2. The newline characters in sideband 2 (progress info) and sideband 3
(error message) should be preserved, but they are both trimmed.
Will fix the above two issues in subsequent commits.

If an error occurs during an atomic fetch, a redundant error message
will appear at the end of do_fetch(). It was introduced in b3a804663c
(fetch: make `--atomic` flag cover backfilling of tags, 2022-02-17).
Because a failure message is displayed before setting retcode in the
function do_fetch(), calling error() on the err message at the end of
this function may result in redundant or empty error message to be
displayed.
We can remove the redundant error() function, because we know that
the function ref_transaction_abort() never fails. While we can find a
common pattern for calling ref_transaction_abort() by running command
"git grep -A1 ref_transaction_abort", e.g.:
if (ref_transaction_abort(transaction, &error))
error("abort: %s", error.buf);
Following this pattern, we can tolerate the return value of the function
ref_transaction_abort() being changed in the future. We also delay the
output of the err message to the end of do_fetch() to reduce redundant
code. With these changes, the test case "fetch porcelain output
(atomic)" in t5574 will also be fixed.

command. The error output must be empty with the follow assertion:
test_must_be_empty stderr
But this assertion fails if using atomic fetch. Refactor this test case
to use different fetch options by splitting it into three test cases.
1. "setup for fetch porcelain output".
2. "fetch porcelain output": for non-atomic fetch.
3. "fetch porcelain output (atomic)": for atomic fetch.
Add new command "test_commit ..." in the first test case, so that if we
run these test cases individually (--run=4-6), "git rev-parse HEAD~"
command will work properly. Run the above test cases, we can find that
one test case has a known breakage, as shown below:
ok 4 - setup for fetch porcelain output
ok 5 - fetch porcelain output # TODO known breakage vanished
not ok 6 - fetch porcelain output (atomic) # TODO known breakage
The failed test case has an error message with only the error prompt but
no message body, as follows:
'stderr' is not empty, it contains:
error:
In a later commit, we will fix this issue.

The "check-chainlint" target runs automatically when running tests and
performs self-checks to verify that the chainlinter itself produces the
expected output. Originally, the chainlinter was implemented via sed,
but the infrastructure has been rewritten in fb41727b7e (t: retire
unused chainlint.sed, 2022-09-01) to use a Perl script instead.
The rewrite caused some slight whitespace changes in the output that are
ultimately not of much importance. In order to be able to assert that
the actual chainlinter errors match our expectations we thus have to
ignore whitespace characters when diffing them. As the `-w` flag is not
in POSIX we try to use `git diff -w --no-index` before we fall back to
`diff -w -u`.
To accomodate for cases where the host system has no Git installation we
use the locally-compiled version of Git. This can result in problems
though when the Git project's repository is using extensions that the
locally-compiled version of Git doesn't understand. It will refuse to
run and thus cause the checks to fail.
Instead of improving the detection logic, fix our ".expect" files so
that we do not need any post-processing at all anymore. This allows us
to drop the `-w` flag when diffing so that we can always use diff(1)
now.
Note that we keep some of the post-processing of `chainlint.pl` output
intact to strip leading line numbers generated by the script. Having
these would cause a rippling effect whenever we add a new test that
sorts into the middle of existing tests and would require us to
renumerate all subsequent lines, which seems rather pointless.
