Merge branch 'mk/http-backend-content-length'
The earlier attempt barfed when given a CONTENT_LENGTH that is
set to an empty string. RFC 3875 is fairly clear that in this
case we should not read any message body, but we've been reading
through to the EOF in previous versions (which did not even pay
attention to the environment variable), so keep that behaviour for
now in this late update.
v2.19.0-rc0~165^2~1 (submodule: ensure core.worktree is set after
update, 2018-06-18) assumes an "absorbed" submodule layout, where the
submodule's Git directory is in the superproject's .git/modules/
directory and .git in the submodule worktree is a .git file pointing
there. In particular, it uses $GIT_DIR/modules/$name to find the
submodule to find out whether it already has core.worktree set, and it
uses connect_work_tree_and_git_dir if not, resulting in
fatal: could not open sub/.git for writing
The context behind that patch: v2.19.0-rc0~165^2~2 (submodule: unset
core.worktree if no working tree is present, 2018-06-12) unsets
core.worktree when running commands like "git checkout
--recurse-submodules" to switch to a branch without the submodule. If
a user then uses "git checkout --no-recurse-submodules" to switch back
to a branch with the submodule and runs "git submodule update", this
patch is needed to ensure that commands using the submodule directly
are aware of the path to the worktree.
It is late in the release cycle, so revert the whole 3-patch series.
We can try again later for 2.20.

http-backend: allow empty CONTENT_LENGTH
According to RFC3875, empty environment variable is equivalent to unset,
and for CONTENT_LENGTH it should mean zero body to read.
However, unset CONTENT_LENGTH is also used for chunked encoding to indicate
reading until EOF. At least, the test "large fetch-pack requests can be split
across POSTs" from t5551 starts faliing, if unset or empty CONTENT_LENGTH is
treated as zero length body. So keep the existing behavior as much as possible.

commit: don't use generation numbers if not needed
In 3afc679b "commit: use generations in paint_down_to_common()",
the queue in paint_down_to_common() was changed to use a priority
order based on generation number before commit date. This served
two purposes:
1. When generation numbers are present, the walk guarantees
correct topological relationships, regardless of clock skew in
commit dates.
2. It enables short-circuiting the walk when the min_generation
parameter is added in d7c1ec3e "commit: add short-circuit to
paint_down_to_common()". This short-circuit helps commands
like 'git branch --contains' from needing to walk to a merge
base when we know the result is false.
The commit message for 3afc679b includes the following sentence:
This change does not affect the number of commits that are
walked during the execution of paint_down_to_common(), only
the order that those commits are inspected.
This statement is incorrect. Because it changes the order in which
the commits are inspected, it changes the order they are added to
the queue, and hence can change the number of loops before the
queue_has_nonstale() method returns true.
This change makes a concrete difference depending on the topology
of the commit graph. For instance, computing the merge-base between
consecutive versions of the Linux kernel has no effect for versions
after v4.9, but 'git merge-base v4.8 v4.9' presents a performance
regression:
v2.18.0: 0.122s
v2.19.0-rc1: 0.547s
HEAD: 0.127s
To determine that this was simply an ordering issue, I inserted
a counter within the while loop of paint_down_to_common() and
found that the loop runs 167,468 times in v2.18.0 and 635,579
times in v2.19.0-rc1.
The topology of this case can be described in a simplified way
here:
v4.9
| \
| \
v4.8 \
| \ \
| \ |
... A B
| / /
| / /
|/__/
C
Here, the "..." means "a very long line of commits". By generation
number, A and B have generation one more than C. However, A and B
have commit date higher than most of the commits reachable from
v4.8. When the walk reaches v4.8, we realize that it has PARENT1
and PARENT2 flags, so everything it can reach is marked as STALE,
including A. B has only the PARENT1 flag, so is not STALE.
When paint_down_to_common() is run using
compare_commits_by_commit_date, A and B are removed from the queue
early and C is inserted into the queue. At this point, C and the
rest of the queue entries are marked as STALE. The loop then
terminates.
When paint_down_to_common() is run using
compare_commits_by_gen_then_commit_date, B is removed from the
queue only after the many commits reachable from v4.8 are explored.
This causes the loop to run longer. The reason for this regression
is simple: the queue order is intended to not explore a commit
until everything that _could_ reach that commit is explored. From
the information gathered by the original ordering, we have no
guarantee that there is not a commit D reachable from v4.8 that
can also reach B. We gained absolute correctness in exchange for
a performance regression.
The performance regression is probably the worse option, since
these incorrect results in paint_down_to_common() are rare. The
topology required for the performance regression are less rare,
but still require multiple merge commits where the parents differ
greatly in generation number. In our example above, the commit A
is as important as the commit B to demonstrate the problem, since
otherwise the commit C will sit in the queue as non-stale just as
long in both orders.
The solution provided uses the min_generation parameter to decide
if we should use generation numbers in our ordering. When
min_generation is equal to zero, it means that the caller has no
known cutoff for the walk, so we should rely on our commit-date
heuristic as before; this is the case with merge_bases_many().
When min_generation is non-zero, then the caller knows a valuable
cutoff for the short-circuit mechanism; this is the case with
remove_redundant() and in_merge_bases_many().

Using git-am (or am-based rebase) to apply the changes from branch onto
master results in the following tree:
Result: bar_merged, goo/{file1, file2, file3}
This is not what users want; they did not rename foo/ -> goo/, they only
renamed one file within that directory. The reason this happens is am
constructs fake trees (via build_fake_ancestor()) of the following form:
You can see that merge_recursive_generic() would see branch_bfa as renaming
foo/ -> goo/, and master as just adding both foo/file1 and foo/file2. As
such, it ends up with goo/{file1, file2, file3}
The core problem is that am does not have access to the original trees; it
can only construct trees using the blobs involved in the patch. As such,
it is not safe to perform directory rename detection within am -3.

after we check for hashes and arrays, assume those are JSON objects,
and coerce them to a known boolean value.

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

hashcmp: assert constant hash size
Prior to 509f6f62a4 (cache: update object ID functions for
the_hash_algo, 2018-07-16), hashcmp() called memcmp() with a
constant size of 20 bytes. Some compilers were able to turn
that into a few quad-word comparisons, which is faster than
actually calling memcmp().
In 509f6f62a4, we started using the_hash_algo->rawsz
instead. Even though this will always be 20, the compiler
doesn't know that while inlining hashcmp() and ends up just
generating a call to memcmp().
Eventually we'll have to deal with multiple hash sizes, but
for the upcoming v2.19, we can restore some of the original
performance by asserting on the size. That gives the
compiler enough information to know that the memcmp will
always be called with a length of 20, and it performs the
same optimization.
Here are numbers for p0001.2 run against linux.git on a few

You can see that v2.19 is a little slower than v2.18. This
commit ended up slightly faster than v2.18, but there's a
fair bit of run-to-run noise (the generated code in the two
cases is basically the same). This patch does seem to be
consistently 1-2% faster than v2.19.
I tried changing hashcpy(), which was also touched by 509f6f62a4, in the same way, but couldn't measure any
speedup. Which makes sense, at least for this workload. A
traversal of the whole commit graph requires looking up
every entry of every tree via lookup_object(). That's many
multiples of the numbers of objects in the repository (most
of the lookups just return "yes, we already saw that
object").

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.)

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.

t7501-commit: drop silly command substitution

bit if there is a meaningful merge., 2016-02-15), runs the following
unnecessary and downright bogus command substitution:
! $(git merge --no-commit commit-1) &&

attempts to execute its output:
Merging: 80f2ea2 commit 2

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.
Remove this command substitution and use 'test_must_fail' to ensure
that 'git merge' fails.

commit: use timestamp_t for author_date_slab
The author_date_slab is used to store the author date of a commit
when walking with the --author-date flag in rev-list or log. This
was added as an 'unsigned long' in
Since 'unsigned long' is ambiguous in its bit-ness across platforms
(64-bit in Linux, 32-bit in Windows, for example), most references
to the author dates in commit.c were converted to timestamp_t in
dddbad72 "timestamp_t: a new data type for timestamps"
However, the slab definition was missed, leading to a mismatch in
the data types in Windows. This would not reveal itself as a bug
unless someone authors a commit after February 2106, but commits
can store anything as their author date.

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'.
