Today, we can use devtool/recipetool to create recipes for python projects using the github url or the direct realse tarball of the project, but the create_buildsys_python plugin doesn't support the pypi class, since we cannot know from the extracted source if the package is available on pypi or not.
By implementing the new optional process_url callback, we can detect that the url is a pypi one (i.e 'https://pypi.org/project/<package>') and retrieve the release tarball location. Also detect if the url points to a release tarball hosted on "files.pythonhosted.iorg" (i.e https://files.pythonhosted.org/packages/...) In both cases, adds the pypi class, remove 'S' and 'SRC_URIxxx' variables from the created recipe as they will be handled by the pypi class and add the PYPI_PACKAGE variable This helps to produce cleaner recipes when package is hosted on pypi. If the url points to a github url or a release tarball not coming from "files.pythonhosted.org" website, the created recipe is the same as before. One can also use the newly added "--no-pypi" switch to devtool/recipetool to NOT inherit from pypi class on matching url, to keep legacy behaviour. To create a recipe for a pypi package, one can now use one of the new following syntax (using recipetool create / devtool add): * recipetool create https://pypi.org/project/<package> * recipetool create https://pypi.org/project/<package>/<version> * recipetool create https://pypi.org/project/<package> --version <version> or the old syntax: * recipetool create https://files.pythonhosted.org/packages/<...> Signed-off-by: Julien Stephan <jstep...@baylibre.com> --- scripts/lib/devtool/standard.py | 3 + scripts/lib/recipetool/create.py | 1 + .../lib/recipetool/create_buildsys_python.py | 72 +++++++++++++++++++ 3 files changed, 76 insertions(+) diff --git a/scripts/lib/devtool/standard.py b/scripts/lib/devtool/standard.py index d53fb810071..f18ebaa70d3 100644 --- a/scripts/lib/devtool/standard.py +++ b/scripts/lib/devtool/standard.py @@ -147,6 +147,8 @@ def add(args, config, basepath, workspace): extracmdopts += ' -a' if args.npm_dev: extracmdopts += ' --npm-dev' + if args.no_pypi: + extracmdopts += ' --no-pypi' if args.mirrors: extracmdopts += ' --mirrors' if args.srcrev: @@ -2260,6 +2262,7 @@ def register_commands(subparsers, context): group.add_argument('--no-same-dir', help='Force build in a separate build directory', action="store_true") parser_add.add_argument('--fetch', '-f', help='Fetch the specified URI and extract it to create the source tree (deprecated - pass as positional argument instead)', metavar='URI') parser_add.add_argument('--npm-dev', help='For npm, also fetch devDependencies', action="store_true") + parser_add.add_argument('--no-pypi', help='Do not inherit pypi class', action="store_true") parser_add.add_argument('--version', '-V', help='Version to use within recipe (PV)') parser_add.add_argument('--no-git', '-g', help='If fetching source, do not set up source tree as a git repository', action="store_true") group = parser_add.add_mutually_exclusive_group() diff --git a/scripts/lib/recipetool/create.py b/scripts/lib/recipetool/create.py index 5c5ac7ae403..963aa91421e 100644 --- a/scripts/lib/recipetool/create.py +++ b/scripts/lib/recipetool/create.py @@ -1413,6 +1413,7 @@ def register_commands(subparsers): parser_create.add_argument('-B', '--srcbranch', help='Branch in source repository if fetching from an SCM such as git (default master)') parser_create.add_argument('--keep-temp', action="store_true", help='Keep temporary directory (for debugging)') parser_create.add_argument('--npm-dev', action="store_true", help='For npm, also fetch devDependencies') + parser_create.add_argument('--no-pypi', action="store_true", help='Do not inherit pypi class') parser_create.add_argument('--devtool', action="store_true", help=argparse.SUPPRESS) parser_create.add_argument('--mirrors', action="store_true", help='Enable PREMIRRORS and MIRRORS for source tree fetching (disabled by default).') parser_create.set_defaults(func=create_recipe) diff --git a/scripts/lib/recipetool/create_buildsys_python.py b/scripts/lib/recipetool/create_buildsys_python.py index b620e3271b1..5e07222ece1 100644 --- a/scripts/lib/recipetool/create_buildsys_python.py +++ b/scripts/lib/recipetool/create_buildsys_python.py @@ -18,7 +18,11 @@ import os import re import sys import subprocess +import json +import urllib.request from recipetool.create import RecipeHandler +from urllib.parse import urldefrag +from recipetool.create import determine_from_url logger = logging.getLogger('recipetool') @@ -111,6 +115,74 @@ class PythonRecipeHandler(RecipeHandler): def __init__(self): pass + def process_url(self, args, classes, handled, extravalues): + """ + Convert any pypi url https://pypi.org/project/<package>/<version> into https://files.pythonhosted.org/packages/source/... + which corresponds to the archive location, and add pypi class + """ + + if 'url' in handled: + return None + + fetch_uri = None + source = args.source + required_version = args.version if args.version else None + match = re.match(r'https?://pypi.org/project/([^/]+)(?:/([^/]+))?/?$', urldefrag(source)[0]) + if match: + package = match.group(1) + version = match.group(2) if match.group(2) else required_version + + json_url = f"https://pypi.org/pypi/%s/json" % package + response = urllib.request.urlopen(json_url) + if response.status == 200: + data = json.loads(response.read()) + if not version: + #
