nest: migrate to homebrew/core #21561

tammoippen · 2017-12-11T12:31:08Z

Have you followed the guidelines for contributing?
Have you checked that there aren't other open pull requests for the same formula update/change?
Have you built your formula locally with brew install --build-from-source <formula>, where <formula> is the name of the formula you're submitting?
Does your build pass brew audit --strict <formula> (after doing brew install <formula>)?

Migrating because of: https://github.com/Homebrew/homebrew-science/issues/6331

Companion PR: https://github.com/Homebrew/homebrew-science/pull/6489

Failing because of dependency on matplotlib, which is also scheduled for migration (see top of list https://github.com/Homebrew/homebrew-science/issues/6331).

It's unlikely matplotlib will be accepted into homebrew/core. You should vendor as is done with most python resources.

tammoippen · 2017-12-11T13:20:15Z

👍 will do so.

Formula/nest.rb

+
+  requires_py3 = []
+  requires_py3 << "with-python3" if build.with? "python3"
+  depends_on "numpy" => requires_py3


depends_on "foo" => "with-bar" is an audit failure, which this use of a variable manages to circumvent. It's also unnecessary here since numpy builds with both python2 and python3 by default. Unless we're building both python2 and python3 bindings by default for nest, numpy will need to be vendored.

In Python for Formula Authors the matplotlib formula is given as an example for python dependencies and I followed their lead - and they use the variable to circumvent audit failure. Vendoring scipy and numpy now. matplotlib actually is not a necessary requirement - only used in examples, hence removing it from dependencies.

That documentation is dated.

+  requires_py3 = []
+  requires_py3 << "with-python3" if build.with? "python3"
+  depends_on "numpy" => requires_py3

same comment as above

Formula/nest.rb

+  end
+
+  def install
+    ENV.delete("CFLAGS")


This should never be needed. Ditto CXXFLAGS below.

Formula/nest.rb

+  option "without-openmp", "Build without OpenMP support."
+  needs :openmp if build.with? "openmp"
+

just require it

+
+  option "with-python3", "Build Python3 bindings (PyNEST) instead of Python2 bindings."
+  option "without-openmp", "Build without OpenMP support."
+  needs :openmp if build.with? "openmp"


don't need this option

I do not understand, why we don't need this option? nest can be build with or without OpenMP. Are you suggesting, we build with OpenMP by default?

I'm saying we should have no openmp option.

ilovezfs · 2017-12-11T13:23:54Z

Formula/nest.rb

+  needs :openmp if build.with? "openmp"
+
+  depends_on "gsl" => :recommended
+  depends_on :mpi => [:optional, :cc, :cxx]


don't need this option

Same here. Are you suggesting we build with MPI by default?

I'm saying we should have no mpi option.

Formula/nest.rb

comment isn't needed

ilovezfs · 2017-12-11T13:25:42Z

Formula/nest.rb

+    inreplace bin/"nest-config",
+        %r{#{HOMEBREW_REPOSITORY}/Library/Homebrew/shims.*/super},
+        "#{HOMEBREW_PREFIX}/bin",
+        FALSE


Not sure what the deal is with this inreplace but any use of the false argument is essentially a bug by definition.

See https://github.com/Homebrew/homebrew-science/pull/6479 why we introduced the inreplace and https://github.com/Homebrew/homebrew-science/pull/6488 for the FALSE part.

ilovezfs · 2017-12-11T13:26:07Z

Formula/nest.rb

don't need this

Without this, the --HEAD option is gone. Is this intended?

ilovezfs · 2017-12-11T13:26:47Z

Formula/nest.rb

+  depends_on "matplotlib" => requires_py3
+
+  depends_on "libtool" => :run
+  depends_on "readline" => :run


the => :run isn't needed. readline would never be => :build

ilovezfs · 2017-12-11T13:27:03Z

Formula/nest.rb

+
+  depends_on "libtool" => :run
+  depends_on "readline" => :run
+  depends_on "cmake" => :build


=> :build should go above the rest

ilovezfs · 2017-12-11T13:27:22Z

Formula/nest.rb

+
+  fails_with :clang do
+    cause <<-EOS.undent
+      Building NEST with clang is not stable. See https://github.com/nest/nest-simulator/issues/74 .


If this is true, it doesn't belong in homebrew/core.

Seems fixed, see nest/nest-simulator#732. On the other hand, clang from macOS does not support OpenMP (last time i checked) and we would have to rely on gcc anyway. Removing fails_with part.

ilovezfs · 2017-12-12T11:12:14Z

Formula/nest.rb

+  depends_on "libtool" => :run
+  depends_on "readline"

+  patch :DATA


New formulae must build without patching.

It's unlikely matplotlib will be accepted into homebrew/core. You should vendor as is done with most python resources.

numpy and scipy are both in Homebrew/core. What's the reason that matplotlib should not be migrated to core?

ilovezfs · 2017-12-13T06:52:34Z

It takes under a minute to build and we don't usually package python libraries. I'm considering removing numpy and scipy too.

DomT4 · 2017-12-13T07:29:30Z

Formula/nest.rb

+         ] {join} Fold
+        } Function def
+      EOS
+      File.open(ENV["HOME"]+"/.nestrc", "w") { |file| file.write(nestrc) }


(testpath/".nestrc").write nestrc, no?

nest will look in HOME for .nestrc... if testpath is equal to HOME in the testing-sandbox, then this would be ok. But since there will not be a MPI build, .nestrc is not needed and those lines will go anyway.

Yeah, testpath is HOME here, as is buildpath during def install, although the latter may one day change as it has some side-effects that aren't completely desirable.

tammoippen · 2017-12-13T09:41:23Z

I will prepare a PR upstream with changes making the patch unnecessary, but I doubt there will be release in the near future (2.14 is relative fresh for nest ~20. Oct.). Also, I am a bit reluctant to vendor matplotlib: I found no other formula in core vendoring matplotlib; and besides the dead code in the tests (in the patch), matplotlib is actually not necessary for nest; also looking at matplotlib formula, there is some complexity I do not want to mirror in nest's formula just for vendoring.

I am ok with the other requests, but this might be a deal breaker until a new release of nest? I guess it is not possible to use a git-commit instead of a stable release?

ilovezfs · 2017-12-13T09:42:59Z

If the patch has been accepted upstream, we can apply it with a patch do block and a url.

Due to `brew audit --strict homebrew/core/nest`: * removing `revision 1` * removing `depends_on :python unless OS.mac?`

* vendor python packages * make OpenMP and MPI default * some restructuring

ilovezfs · 2017-12-25T13:52:19Z

@BrewTestBot test this please

ilovezfs · 2017-12-25T13:53:18Z

Formula/nest.rb

+    end
+
+    # add nosetest executable to path
+    ENV.prepend_create_path "PATH", libexec/"bin"


should just be prepend_path
