f237c8b6fe ("commit-graph: implement git-commit-graph write",

Ævar Arnfjörð Bjarmason 8c97e38731 tests: fix version-specific portability issue in Perl JSON
The test guarded by PERLJSON added in 75459410ed ("json_writer: new
routines to create JSON data", 2018-07-13) assumed that a JSON boolean
value like "true" or "false" would be represented as "1" or "0" in
Perl.

This behavior can't be relied upon, e.g. with JSON.pm 2.50 and
JSON::PP.  A JSON::PP::Boolean object will be represented as "true"
or "false". To work around this let's check if we have any refs left
after we check for hashes and arrays, assume those are JSON objects,
and coerce them to a known boolean value.

The behavior of this test still looks odd to me. Why implement our own
ad-hoc encoder just for some one-off test, as opposed to say Perl's
own Data::Dumper with Sortkeys et al? But with this change it works,
so let's leave it be.

Ævar Arnfjörð Bjarmason b2fa7a2372 tests: fix and add lint for non-portable seq
The seq command is not in POSIX, and doesn't exist on
e.g. OpenBSD. We've had the test_seq wrapper since d17cf5f3a3 ("tests:
Introduce test_seq", 2012-08-04), but use of it keeps coming back,
e.g. in the recently added "fetch negotiator" tests being added here.

So let's also add a check to "make test-lint". The regex is aiming to
capture the likes of $(seq ..) and "seq" as a stand-alone command,
without capturing some existing cases where we e.g. have files called
"seq", as \bseq\b would do.

Ævar Arnfjörð Bjarmason 2a59a6ef20 tests: fix and add lint for non-portable head -c N
The "head -c BYTES" option is non-portable (not in POSIX[1]). Change
such invocations to use the test_copy_bytes wrapper added in
48860819e8 ("t9300: factor out portable "head -c" replacement",
2016-06-30).

This fixes a test added in 9d2e330b17 ("ewah_read_mmap: bounds-check
mmap reads", 2018-06-14), which has been breaking
t5310-pack-bitmaps.sh on OpenBSD since 2.18.0. The OpenBSD ports
already have a similar workaround after their upgrade to 2.18.0[2].

I have not tested this on IRIX, but according to 4de0bbd898 ("t9300:
use perl "head -c" clone in place of "dd bs=1 count=16000" kluge",
2010-12-13) this invocation would have broken things there too.

Also, change a valgrind-specific codepath in test-lib.sh to use this
wrapper. Given where valgrind runs I don't think this would ever
become a portability issue in practice, but it's easier to just use
the wrapper than introduce some exception for the "make test-lint"
check being added here.

Jeff King ffce7f590f sequencer: ignore "---" divider when parsing trailers
When the sequencer code appends a signoff or cherry-pick
origin, it uses the default trailer-parsing options, which
treat "---" as the end of the commit message. As a result,
it may be fooled by a commit message that contains that
string and fail to find the existing trailer block. Even
more confusing, the actual append code does not know about
"---", and always appends to the end of the string. This can
lead to bizarre results. E.g., appending a signoff to a
commit message like this:

  subject

  body
  ---
  these dashes confuse the parser!

  Signed-off-by: A

results in output with a final block like:

  Signed-off-by: A

  Signed-off-by: A

The parser thinks the final line of the message is "body",
and ignores everything else, claiming there are no trailers.
So we output an extra newline separator (wrong) and add a
duplicate signoff (also wrong).

Since we know we are feeding a pure commit message, we can
simply tell the parser to ignore the "---" divider.

Jeff King e5fba5d558 pretty, ref-filter: format %(trailers) with no_divider option
In both of these cases we know that we are feeding the
trailer-parsing code a pure commit message. We should tell
it so, which avoids false positives for a commit message

Jeff King 1688c9a489 interpret-trailers: allow suppressing "---" divider
Even with the newly-tightened "---" parser, it's still
possible for a commit message to trigger a false positive if
it contains something like "--- foo". If the caller knows
that it has only a single commit message, it can now tell us
with the "--no-divider" option, eliminating any false
positives.

If we were designing this from scratch, I'd probably make
this the default. But we've advertised the "---" behavior in
the documentation since interpret-trailers has existed.
Since it's meant to be scripted, breaking that would be a
bad idea.

Note that the logic is in the underlying trailer.c code,
which is used elsewhere. The default there will keep the
current behavior, but many callers will benefit from setting
this new option. That's left for future patches.

Jeff King c188668e38 interpret-trailers: tighten check for "---" patch boundary
The interpret-trailers command accepts not only raw commit
messages, but it also can manipulate trailers in
format-patch output. That means it must find the "---"
boundary separating the commit message from the patch.
However, it does so by looking for any line starting with
"---", regardless of whether there is further content.

This is overly lax compared to the parsing done in
mailinfo.c's patchbreak(), and may cause false positives
(e.g., t/perf output tables uses dashes; if you cut and
paste them into your commit message, it fools the parser).

We could try to reuse patchbreak() here, but it actually has
several heuristics that are not of interest to us (e.g.,
matching "diff -" without a three-dash separator or even a
CVS "Index:" line). We're not interested in taking in
whatever random cruft people may send, but rather handling
git-formatted patches.

Note that the existing documentation was written in a loose
way, so technically we are changing the behavior from what
it said. But this should implement the original intent in a
more accurate way.

SZEDER Gábor 7afb0d6777 t/lib-rebase.sh: support explicit 'pick' commands in 'fake_editor.sh'
The verbose output of the test 'reword without issues functions as
intended' in 't3423-rebase-reword.sh', added in a9279c6785 (sequencer:
do not squash 'reword' commits when we hit conflicts, 2018-06-19),
contains the following error output:

  sed: -e expression #1, char 2: extra characters after command

This error comes from within the 'fake-editor.sh' script created by
'lib-rebase.sh's set_fake_editor() function, and the root cause is the
FAKE_LINES="pick 1 reword 2" variable in the test in question, in
particular the "pick" word.  'fake-editor.sh' assumes 'pick' to be the
default rebase command and doesn't support an explicit 'pick' command
in FAKE_LINES.  As a result, 'pick' will be used instead of a line
number when assembling the following 'sed' script:

  sed -n picks/^pick/pick/p

which triggers the aforementioned error.

Luckily, this didn't affect the test's correctness: the erroring 'sed'
command doesn't write anything to the todo script, and processing the
rest of FAKE_LINES generates the desired todo script, as if that
'pick' command were not there at all.

The minimal fix would be to remove the 'pick' word from FAKE_LINES,
but that would leave us susceptible to similar issues in the future.

Instead, teach the fake-editor script to recognize an explicit 'pick'
command, which is still a fairly trivial change.

In the future we might want to consider reinforcing this fake editor
script with an &&-chain and stricter parsing of the FAKE_LINES
variable (e.g. to error out when encountering unknown rebase commands
or commands and line numbers in the wrong order).

SZEDER Gábor 2745817028 t3420-rebase-autostash: don't try to grep non-existing files
Several tests in 't3420-rebase-autostash.sh' start various rebase
processes that are expected to fail because of merge conflicts.  These
tests then run '! grep' to ensure that the autostash feature did its
job, and the dirty contents of a file is gone.  However, due to the
test repo's history and the choice of upstream branch that file
shouldn't exist in the conflicted state at all.  Consequently, this
'grep' doesn't fail as expected, because it can't find the dirty
content, but it fails because it can't open the file.

Tighten this check by using 'test_path_is_missing' instead, thereby
avoiding unexpected errors from 'grep' as well.

SZEDER Gábor b89b4a660c t6018-rev-list-glob: fix 'empty stdin' test
Prior to d3c6751b18 (tests: make use of the test_must_be_empty
function, 2018-07-27), in the test 'rev-list should succeed with empty
output on empty stdin' in 't6018-rev-list-glob' the empty 'expect'
file served dual purpose: besides specifying the expected output, as
usual, it also served as empty input for 'git rev-list --stdin'.

Then d3c6751b18 came along, and, as part of the conversion to
'test_must_be_empty', removed this empty 'expect' file, not realizing
its secondary purpose.  Redirecting stdin from the now non-existing
file failed the test, but since this test expects failure in the first
place, this issue went unnoticed.

Redirect 'git rev-list's stdin explicitly from /dev/null to provide
empty input.  (Strictly speaking we don't need this redirection,
because the test script's stdin is already redirected from /dev/null
anyway, but I think it's better to be explicit about it.)

SZEDER Gábor c8b35b95e1 t4051-diff-function-context: read the right file
The test ' context does not include preceding empty lines' in the
block of tests 'change with long common tail and no context' in
't4051-diff-function-context.sh' tries to read the file
'long_common_tail.diff.diff', but that file doesn't exist as its name
contains one more '.diff' suffixes than necessary.

Despite this error the test still succeeded without checking what it's
supposed to, because this erroneous read is done on the line:

  test "$(first_context_line <long_common_tail.diff.diff)" != " "

which means that:

  - the command substitution hides the error, so it won't fail the
    test, and

  - the result of the command substitution is the empty string, which
    is, of course, not equal to a single space character, so the
    condition is fulfilled, and the test succeeds.

As a minimal fix, fix the name of the file to be read.

In the future we might want to reorganize this test script (1) to use
'test_cmp' instead of 'test's and command substitutions to catch
failing commands and to provide helpful error messages, and (2) to
specify what the expected result actually _is_ instead of what it
isn't.

attempts to execute its output:

  virtual commit-1
  found 1 common ancestor:
  e60d113 Initial commit
  Auto-merging test-file
  CONFLICT (content): Merge conflict in test-file
  Automatic merge failed; fix conflicts and then commit the result.

as a command, which most likely fails, because there is no such
command as "Merging:".  Then '!' negates the failed exit status, the
test continues, and eventually succeeds.

that 'git merge' fails.

SZEDER Gábor 1c5e94f459 tests: use 'test_must_be_empty' instead of 'test_cmp <empty> <out>'
Using 'test_must_be_empty' is shorter and more idiomatic than

  >empty &&
  test_cmp empty out

as it saves the creation of an empty file.  Furthermore, sometimes the
expected empty file doesn't have such a descriptive name like 'empty',
and its creation is far away from the place where it's finally used
for comparison (e.g. in 't7600-merge.sh', where two expected empty
files are created in the 'setup' test, but are used only about 500
lines later).

These cases were found by instrumenting 'test_cmp' to error out the
test script when it's used to compare empty files, and then converted
manually.

Note that even after this patch there still remain a lot of cases
where we use 'test_cmp' to check empty files:

  - Sometimes the expected output is not hard-coded in the test, but
    'test_cmp' is used to ensure that two similar git commands produce
    the same output, and that output happens to be empty, e.g. the
    test 'submodule update --merge  - ignores --merge  for new
    submodules' in 't7406-submodule-update.sh'.

  - Repetitive common tasks, including preparing the expected results
    and running 'test_cmp', are often extracted into a helper
    function, and some of this helper's callsites expect no output.

  - For the same reason as above, the whole 'test_expect_success'
    block is within a helper function, e.g. in 't3070-wildmatch.sh'.

  - Or 'test_cmp' is invoked in a loop, e.g. the test 'cvs update
    (-p)' in 't9400-git-cvsserver-server.sh'.

Augment commit_graph_compatible(r) to return false when the given
repository r has commit grafts or is a shallow clone. Test that in these
situations we ignore existing commit-graph files and we do not write new
commit-graph files.

Derrick Stolee d6538246d3 commit-graph: not compatible with replace objects
Create new method commit_graph_compatible(r) to check if a given
repository r is compatible with the commit-graph feature. Fill the
method with a check to see if replace-objects exist. Test this
interaction succeeds, including ignoring an existing commit-graph and
failing to write a new commit-graph. However, we do ensure that
we write a new commit-graph by setting read_replace_refs to 0, thereby
ignoring the replace refs.

Junio C Hamano 59a255aef0 sideband: do not read beyond the end of input
The caller of maybe_colorize_sideband() gives a counted buffer
<src, n>, but the callee checked src[] as if it were a NUL terminated
buffer.  If src[] had all isspace() bytes in it, we would have made
n negative, and then

 (1) made number of strncasecmp() calls to see if the remaining
     bytes in src[] matched keywords, reading beyond the end of the
     array (this actually happens even if n does not go negative),
     and/or

 (2) called strbuf_add() with negative count, most likely triggering
     the "you want to use way too much memory" error due to unsigned
     integer overflow.

Fix both issues by making sure we do not go beyond &src[n].

In the longer term we may want to accept size_t as parameter for
clarity (even though we know that a sideband message we are painting
typically would fit on a line on a terminal and int is sufficient).
Write it down as a NEEDSWORK comment.

Phillip Wood bc9238bb09 rebase -i: fix SIGSEGV when 'merge <branch>' fails
If a merge command in the todo list specifies just a branch to merge
with no -C/-c argument then item->commit is NULL. This means that if
there are merge conflicts error_with_patch() is passed a NULL commit
which causes a segmentation fault when make_patch() tries to look it up.

This commit implements a minimal fix which fixes the crash and allows
the user to successfully commit a conflict resolution with 'git rebase
--continue'. It does not write .git/rebase-merge/patch,
.git/rebase-merge/stopped-sha or update REBASE_HEAD. To sensibly get the
hashes of the merge parents would require refactoring do_merge() to
extract the code that parses the merge parents into a separate function
which error_with_patch() could then use to write the parents into the
stopped-sha file. To create meaningful output make_patch() and 'git
rebase --show-current-patch' would also need to be modified to diff the
merge parent and merge base in this case.

SZEDER Gábor 10c600172c t5310-pack-bitmaps: fix bogus 'pack-objects to file can use bitmap' test
The test 'pack-objects to file can use bitmap' added in 645c432d61
(pack-objects: use reachability bitmap index when generating
non-stdout pack, 2016-09-10) is silently buggy and doesn't check what
it's supposed to.

In 't5310-pack-bitmaps.sh', the 'list_packed_objects' helper function
does what its name implies by running:

  git show-index <"$1" | cut -d' ' -f2

The test in question invokes this function like this:

  list_packed_objects <packa-$packasha1.idx >packa.objects &&
  list_packed_objects <packb-$packbsha1.idx >packb.objects &&
  test_cmp packa.objects packb.objects

Note how these two callsites don't specify the name of the pack index
file as the function's parameter, but redirect the function's standard
input from it.  This triggers an error message from the shell, as it
has no filename to redirect from in the function, but this error is
ignored, because it happens upstream of a pipe.  Consequently, both
invocations produce empty 'pack{a,b}.objects' files, and the
subsequent 'test_cmp' happily finds those two empty files identical.

Fix these two 'list_packed_objects' invocations by specifying the pack
index files as parameters.  Furthermore, eliminate the pipe in that
function by replacing it with an &&-chained pair of commands using an
intermediate file, so a failure of 'git show-index' or the shell
redirection will fail the test.

Jeff King 0750bb5b51 cat-file: support "unordered" output for --batch-all-objects
If you're going to access the contents of every object in a
packfile, it's generally much more efficient to do so in
pack order, rather than in hash order. That increases the
locality of access within the packfile, which in turn is
friendlier to the delta base cache, since the packfile puts
related deltas next to each other. By contrast, hash order
is effectively random, since the sha1 has no discernible
relationship to the content.

This patch introduces an "--unordered" option to cat-file
which iterates over packs in pack-order under the hood. You
can see the results when dumping all of the file content:

  $ time ./git cat-file --batch-all-objects --buffer --batch | wc -c
  6883195596

  real	0m44.491s
  user	0m42.902s
  sys	0m5.230s

  $ time ./git cat-file --unordered \
                        --batch-all-objects --buffer --batch | wc -c
  6883195596

  real	0m6.075s
  user	0m4.774s
  sys	0m3.548s

Same output, different order, way faster. The same speed-up
applies even if you end up accessing the object content in a
different process, like:

  git cat-file --batch-all-objects --buffer --batch-check |
  grep blob |
  git cat-file --batch='%(objectname) %(rest)' |
  wc -c

Adding "--unordered" to the first command drops the runtime
in git.git from 24s to 3.5s.

  Side note: there are actually further speedups available
  for doing it all in-process now. Since we are outputting
  the object content during the actual pack iteration, we
  know where to find the object and could skip the extra
  lookup done by oid_object_info(). This patch stops short
  of that optimization since the underlying API isn't ready
  for us to make those sorts of direct requests.

So if --unordered is so much better, why not make it the
default? Two reasons:

  1. We've promised in the documentation that --batch-all-objects
     outputs in hash order. Since cat-file is plumbing,
     people may be relying on that default, and we can't
     change it.

  2. It's actually _slower_ for some cases. We have to
     compute the pack revindex to walk in pack order. And
     our de-duplication step uses an oidset, rather than a
     sort-and-dedup, which can end up being more expensive.
     If we're just accessing the type and size of each
     object, for example, like:

       git cat-file --batch-all-objects --buffer --batch-check

     my best-of-five warm cache timings go from 900ms to
     1100ms using --unordered. Though it's possible in a
     cold-cache or under memory pressure that we could do
     better, since we'd have better locality within the
     packfile.

And one final question: why is it "--unordered" and not
"--pack-order"? The answer is again two-fold:

  1. "pack order" isn't a well-defined thing across the
     whole set of objects. We're hitting loose objects, as
     well as objects in multiple packs, and the only
     ordering we're promising is _within_ a single pack. The
     rest is apparently random.

  2. The point here is optimization. So we don't want to
     promise any particular ordering, but only to say that
     we will choose an ordering which is likely to be
     efficient for accessing the object content. That leaves
     the door open for further changes in the future without
     having to add another compatibility option.

Jeff King aa2f5ef500 t1006: test cat-file --batch-all-objects with duplicates
The test for --batch-all-objects in t1006 covers a variety
of object storage situations, but one thing it doesn't cover
is that we avoid mentioning duplicate objects. We won't have
any because running "git repack -ad" will have packed them
all and deleted the loose ones.

This does work (because we sort and de-dup the output list),
but it's good to include it in our test. And doubly so for
when we add an unordered mode which has to de-dup in a
different way.

Note that we cannot just re-create one of the objects, as
Git will omit the write of an object that is already
present. However, we can create a new pack with one of the
objects, which forces the duplication.

One alternative would be to just use "git repack -a" instead
of "-ad". But then _every_ object would be duplicated as
loose and packed, and we might miss a bug that omits packed
objects (because we'd show their loose counterparts).

Eric Sunshine 4f69176feb chainlint: add test of pathological case which triggered false positive
This extract from contrib/subtree/t7900 triggered a false positive due
to three chainlint limitations:

* recognizing only a "blessed" set of here-doc tag names in a subshell
  ("EOF", "EOT", "INPUT_END"), of which "TXT" is not a member

* inability to recognize multi-line $(...) when the first statement of
  the body is cuddled with the opening "$("

* inability to recognize multiple constructs on a single line, such as
  opening a multi-line $(...) and starting a here-doc

Now that all of these shortcomings have been addressed, turn this rather
pathological bit of shell coding into a chainlint test case.

Eric Sunshine 22e3e0241a chainlint: recognize multi-line quoted strings more robustly
chainlint.sed recognizes multi-line quoted strings within subshells:

    echo "abc
        def" >out &&

so it can avoid incorrectly classifying lines internal to the string as
breaking the &&-chain. To identify the first line of a multi-line
string, it checks if the line contains a single quote. However, this is
fragile and can be easily fooled by a line containing multiple strings:

    echo "xyz" "abc
        def" >out &&

Make detection more robust by checking for an odd number of quotes
rather than only a single one.

(Escaped quotes are not handled, but support may be added later.)

The original multi-line string recognizer rather cavalierly threw away
all but the final quote, whereas the new one is careful to retain all
quotes, so the "expected" output of a couple existing chainlint tests is
updated to account for this new behavior.

Eric Sunshine d93871143f chainlint: let here-doc and multi-line string commence on same line
After swallowing a here-doc, chainlint.sed assumes that no other
processing needs to be done on the line aside from checking for &&-chain
breakage; likewise, after folding a multi-line quoted string. However,
it's conceivable (even if unlikely in practice) that both a here-doc and
a multi-line quoted string might commence on the same line:

    cat <<\EOF && echo "foo
    bar"
    data
    EOF

Support this case by sending the line (after swallowing and folding)
through the normal processing sequence rather than jumping directly to
the check for broken &&-chain.

This change also allows other somewhat pathological cases to be handled,
such as closing a subshell on the same line starting a here-doc:

    (
        cat <<-\INPUT)
        data
        INPUT

or, for instance, opening a multi-line $(...) expression on the same
line starting a here-doc:

    x=$(cat <<-\END &&
        data
        END
        echo "x")

among others.

Eric Sunshine c2c29cc03e chainlint: match arbitrary here-docs tags rather than hard-coded names
chainlint.sed swallows top-level here-docs to avoid being fooled by
content which might look like start-of-subshell. It likewise swallows
here-docs in subshells to avoid marking content lines as breaking the
&&-chain, and to avoid being fooled by content which might look like
end-of-subshell, start-of-nested-subshell, or other specially-recognized
constructs.

At the time of implementation, it was believed that it was not possible
to support arbitrary here-doc tag names since 'sed' provides no way to
stash the opening tag name in a variable for later comparison against a
line signaling end-of-here-doc. Consequently, tag names are hard-coded,
with "EOF" being the only tag recognized at the top-level, and only
"EOF", "EOT", and "INPUT_END" being recognized within subshells. Also,
special care was taken to avoid being confused by here-docs nested
within other here-docs.

In practice, this limited number of hard-coded tag names has been "good
enough" for the 13000+ existing Git test, despite many of those tests
using tags other than the recognized ones, since the bodies of those
here-docs do not contain content which would fool the linter.
Nevertheless, the situation is not ideal since someone writing new
tests, and choosing a name not in the "blessed" set could potentially
trigger a false-positive.

To address this shortcoming, upgrade chainlint.sed to handle arbitrary
here-doc tag names, both at the top-level and within subshells.
