From 527ff860f01de34e34f8c7be8e5682745504d774 Mon Sep 17 00:00:00 2001 From: Todd Gamblin Date: Sun, 16 Dec 2018 23:17:23 -0800 Subject: patches: clean up patch.py, directives, and package class properties - cleanup patch.py: - make patch.py constructors more understandable - loosen coupling of patch.py with package - in Package: make package_dir, module, and namespace class properties - These were previously instance properties and couldn't be called from directives, e.g. in patch.create() - make them class properties so that they can be used in class definition - also add some instance properties to delegate to class properties so that prior usage on Package objects still works --- lib/spack/spack/directives.py | 13 +- lib/spack/spack/package.py | 52 +++++--- lib/spack/spack/patch.py | 141 ++++++++++----------- lib/spack/spack/test/cmd/env.py | 2 +- lib/spack/spack/test/install.py | 5 +- lib/spack/spack/test/patch.py | 5 +- .../repos/builtin/packages/catalyst/package.py | 6 +- 7 files changed, 121 insertions(+), 103 deletions(-) diff --git a/lib/spack/spack/directives.py b/lib/spack/spack/directives.py index 9125d55e9a..57492f5c1c 100644 --- a/lib/spack/spack/directives.py +++ b/lib/spack/spack/directives.py @@ -36,12 +36,12 @@ from six import string_types import llnl.util.lang import spack.error +import spack.patch import spack.spec import spack.url import spack.variant from spack.dependency import Dependency, default_deptype, canonical_deptype from spack.fetch_strategy import from_kwargs -from spack.patch import Patch from spack.resource import Resource from spack.version import Version @@ -416,9 +416,14 @@ def patch(url_or_filename, level=1, when=None, working_dir=".", **kwargs): # if this spec is identical to some other, then append this # patch to the existing list. cur_patches = pkg_or_dep.patches.setdefault(when_spec, []) - cur_patches.append( - Patch.create(pkg_or_dep, url_or_filename, level, - working_dir, **kwargs)) + + # if pkg_or_dep is a Dependency, make it a Package + pkg = pkg_or_dep + if isinstance(pkg, Dependency): + pkg = pkg.pkg + + cur_patches.append(spack.patch.create( + pkg, url_or_filename, level, working_dir, **kwargs)) return _execute_patch diff --git a/lib/spack/spack/package.py b/lib/spack/spack/package.py index 279ed89d04..7df500039e 100644 --- a/lib/spack/spack/package.py +++ b/lib/spack/spack/package.py @@ -200,6 +200,29 @@ class PackageMeta( return func return _decorator + @property + def package_dir(self): + """Directory where the package.py file lives.""" + return os.path.abspath(os.path.dirname(self.module.__file__)) + + @property + def module(self): + """Module object (not just the name) that this package is defined in. + + We use this to add variables to package modules.
