During the review of the initial Scalar patch series, it was suggested to
include Scalar in Git's CI builds. Due to some conflicts, this was postponed
to a later patch series: This patch series.

Note that the changes to the GitHub workflow are somewhat transient in
nature: Based on the feedback I received on the Git mailing list, I see some
appetite for turning Scalar into a full-fledged top-level command in Git,
similar to gitk. Therefore my current plan is to do exactly that in the end
(and I already have patches lined up to that end). This will essentially
revert the ci/run-build-and-tests.sh change in this patch series.

This patch series is based on js/scalar-diagnose.

  cmake: optionally build `scalar`, too

Unlike the `Makefile`-based build, the CMake configuration unfortunately
does not let us easily encapsulate Scalar's build definition in the
`contrib/scalar/` subdirectory: The `scalar` executable needs to link in
`libgit.a` and `common-main.o`, for example.

Also, `scalar.c` includes Git's header files, which means that
`scalar.c` needs to be compiled with the very same flags as `libgit.a`
lest `scalar.o` and `libgit.a` have different ideas of, say,
`platform_SHA_CTX`, which would naturally lead to memory corruption,
crashes and quite tricky debugging (talking from experience).

To alleviate that lack of encapsulation somewhat, we guard the Scalar
parts in `CMakeLists.txt` via the `INCLUDE_SCALAR` environment variable.
This not only allows the CMake-based build to exclude Scalar by default,
but also gives better visual cues as to which sections are related to
Scalar.

Since Scalar depends on `libgit.a`, it makes sense to ensure in the CI
and the PR builds that it does not get broken in case of industrious
refactorings of the core Git code (speaking from experience here).

Are you using "encapsulation" here synonymously with "[mostly] lives in
a different file"? If not I don't really see what distinction you're
trying to draw here.

The contrib/scalar/Makefile "shells out" to the top-level MAkefile to
build libgit.a & common-main.o, as well as scalar.o itself.

We've been over this before direction we should take to fully integrate
scalar (see [1]), but leaving that aside this seems by any definition to
be more "encapsulated" than what we have in Makefile &
contrib/scalar/Makefile. I.e. this is isolated in its own sections,
whereas in the Makefile case we have the top-level building scalar,
contrib/scalar/Makefile shelling out to it, and then adding its own
behavior etc.

I don't think there's much point to re-visit the discussions around the
time of [1], clearly you feel differently,

But just on the commit message it seems to have been drafted from some
earlier version.

Perhaps it was based on the earlier version of the scalar series before
I'd pointed out the Makefile dependency issues around scalar.o (which
led you to have contrib/scalar/MAkefile "shell out")?

This seems like it belongs in the Makfile and/or
ci/make-test-artifacts.sh, why does the GitHub-specific CI step need to
know how to appropriately move scalar build artifacts around?

More importantly, this is the "win build", which uses the Makefile (as
opposed to cmake-using vs-build).

We already invoke ci/make-test-artifacts.sh which does a "make
artifacts-tar", which builds them & packs the "git" binary etc. into a
tarball.

But here we're after-the-fact building the scalar binary itself (we
already built scalar.o), so at the end we're left with a tarball that
doesn't contain scalar, but then a ...

...zip file that does because we manually re-do it here? Or maybe I'm
misunderstanding this....

...doesn't it make more sense to just have the Makefile understand
INCLUDE_SCALAR instead of keeping all this logic in main.yml.

I don't really see the logic of insisting that we can't put scalar
special-cases into our Makefile because it's "in contrib", but then
doing that in our main.yml CI.

Ditto duplicated from above. As the context shows if the "artifacts-tar"
target knew how to include scalar this & the above wouldn't be needed,
we'd just run those shell commands.

At the start of "make test" we create t/test-results, that also goes for
contrib/scalar's "test" phase.

Then if we have failures we keep it around, if not we rm -rf it, and
when we run "test" again we rm -rf the old one.

Have you tested what happens when e.g. one/both of scalar tests & "main"
tests fail? I haven't, but I'm fairly sure it's one of:

 * We racily run both, and they'll rm -rf or trip over one another's
   t/test-results.

 * We'll end up with one or the other, but we want the union of both
   (report on all failed tests & their output at the end)

 * We run one at a time (because we don't have "make -k"?), but now if
   e.g. one scalar test happens to fail (or the other way around) we
   won't spot failures in the tests we didn't run.

So I'm not sure, and haven't tested this, but what I can't see from
being familiar with the Makefile logic involve is how this would Just
Work and do what we want, but maybe I'm missing something.

I don't know if we touched on this in particular in past
rounds/discussions, but this edge case is one of many that led to [1],
i.e. if we simply run the tests in the top-level t/ (as other stuff in
contrib does, like the bash completion) we avoid all of these caveats.

I see later you have a "copy Scalar" step which has some duplication
here. The only difference is that you have "make -C contrib/scalar".

Doesn't Scalar get built in our basic "make" build when the
environment includes INCLUDE_SCALAR=YesPlease? So, for that reason I
expected the environment to change, but not need this "make -C ..."

This is a bit isolated. Is there a way to specify the environment
more generally?

Again, this should "just work" when using INCLUDE_SCALAR in the

It's good to start running Scalar builds and tests during CI before
moving from contrib/. We can establish a pattern that the code is
not causing build failures, and demonstrate that the tests succeed
consistently. Better to do that while still in the mode where we can
easily reverse course.

I expect that this won't be a full remote, since we will still want to
exclude Scalar from the build without INCLUDE_SCALAR enabled.

"a full remote"?

Scalar (well, scalar.o, not scalar the binary) has been included in the
default build (including CI) for a while now.

What we haven't been doing until this series it to link it with libgit.a
or running its tests.

So perhaps that's what you mean, but in an earlier series it wasn't
building scalar.o, and I remember there being some confusion on this
point in the past, seemingly based on a mental model of the scalar
patches that pre-dated the re-roll that eventually got merged.

Whoops. My brain is mixed up with the work I've been doing in remote.c.

I meant "a full revert".

I'm talking about scalar the binary being important. I'm glad that
scalar.o has been built already.

Yes, it is important that we revisit these patches with the previous
changes in mind. In particular, I don't see a single reference to
INCLUDE_SCALAR in the tree at the 'next' branch. This is different
from the build in the microsoft/git fork, which is where I've done
all of my own Scalar development.

We had this `INCLUDE_SCALAR` condition in microsoft/git for a while but
since I got the sense that many regulars were in favor of treating
`scalar` like a top-level command (similar to `gitk`), I've since changed
the over-all course to compiling it unconditionally.

The only remnant is the CMake definition, and only in the transitory phase
while Scalar is still in `contrib/scalar/`, and only because I could not
find a better way to encapsulate it.

But yes, if we decide to go with the `INCLUDE_SCALAR` approach, it won't
be a full remove/revert.

These are the raw logs of the `linux-gcc` job of the most recent CI build
of `seen`, as of time of writing:

https://github.com/git/git/commit/7f1978ce8bfe41074df4fc96ff7f2a28e5807fd1/checks/6718714644/logs

When I download those logs and then let my browser search for the term
"scalar", it comes up empty, even if, say, "range-diff.o" is found. Which
is exactly according to my plan: no part of Scalar is to be built unless
explicitly asked for.

The only job that touches it is the `static-analysis` job, which is a bit
unfortunate. But I cannot justify the complexity of the patch it would
take to address that.

In other words: The statement that `scalar.o` is included in the default
build, without any qualifying note about `static-analysis`, is quite
misleading.

Ciao,
Dscho

I originally did it that way, but somewhere along the refactoring, I
removed that `INCLUDE_SCALAR` conditional (except in the CMake
definition).

Hmm.

Now that you mention it, I guess it would be a good idea to reinstate it.
Let me play with that for a bit.

I did that on purpose, to limit the scope as much as possible.

It would of course be an option to set that environment variable for the
entire `vs-build` job. Or even for the entire workflow.

But I thought there was value in keeping the scope focused, so that
contributors who investigate failing builds could figure out quickly, say,
how to reproduce the issue locally.

Thank you for your review! I will play around with the idea to modify the
top-level `Makefile` so that a `make INCLUDE_SCALAR=YepOfCourse` would
automatically include Scalar. I am just concerned that this would already
open the discussion about taking Scalar out of `contrib/`, and I do want
to discourage this discussion before the remaining upstreamable patches
from https://github.com/microsoft/git/pull/479/commits made it into Git's
main branch (except of course the patch to move Scalar out of `contrib`,
https://github.com/microsoft/git/pull/479/commits/0e7b7653b29a).

Thanks,
Dscho

As the person making that claim: Yes that is really misleading, sorry.

I was under the false recollection that since we added it to $(OBJECTS)
we built it by default, as in "make" was building it.

It *is* of course built my "make objects" etc., but due to how our
dependency tree works not to create "git", or even "libgit.a" (the
dependency relationship there being the other way around).

But an you point out (and I'd missed this, but it make sense in
retrospect) I was (accidentally!) right in the "CI" part of that since
we're including it in "make sparse", which is because we create *.sp
files from everything we have a *.o for.

As an aside re the "justify the complexity" the patch to "fix" that
would be rather trivial:

	diff --git a/Makefile b/Makefile
	index 18ca6744a50..aae16d140a5 100644
	--- a/Makefile
	+++ b/Makefile
	@@ -2966,7 +2966,7 @@ t/helper/test-%$X: t/helper/test-%.o GIT-LDFLAGS $(GITLIBS) $(REFTABLE_TEST_LIB)
	 check-sha1:: t/helper/test-tool$X
	 	t/helper/test-sha1.sh
	 
	-SP_OBJ = $(patsubst %.o,%.sp,$(C_OBJ))
	+SP_OBJ = $(patsubst %.o,%.sp,$(filter-out $(SCALAR_OBJECTS),$(C_OBJ)))
	 
	 $(SP_OBJ): %.sp: %.c %.o
	 	$(QUIET_SP)cgcc -no-compile $(ALL_CFLAGS) $(EXTRA_CPPFLAGS) \

But (and I've noted this before) I think the better fix is to just
properly integrate scalar.

We (accidentally) have been building it by default, which the patches to
integrate it sought to explictly avoid to avoid bothering anyone.

But ... nobody's been bothered, so I think if anything this should be a
data point suggesting that we're being overly careful in this case.

I.e. that we don't need the many intermediate steps of adding
special-cases to various components, when there seems to be unanimous
agreement on the end-goal. Can't we just skip to that already?

:)

Upon further reflection, I would like to retract these patches for now.
They do seem a poor fit within the Scalar story arc: in the end, they
won't be needed anyway (after moving Scalar out of `contrib/`).

I talked to Victoria and she kindly agreed to drive the Scalar upstreaming
from here (after v2.37.0, I imagine).

Thanks,

I think at that point we'd basically be talking about integrating some
version of the patch I sent to do that back in October. I re-rolled it
now, including finishing the CMake part that I punted on before:

	https://lore.kernel.org/git/cover-v2-0.1-00000000000-20220623T100554Z-avarab@gmail.com/

As noted in the CL I saw Victoria pushed out a WIP version that was
taking the same approach, but as she apparently wasn't aware of the
previous effort in the area was bound to still run into the same issues
with the parts she missed, which that 1-patch series addresses.
