gnu: python: Normalize sys.prefix in sitecustomize.py.

2024-08-31T08:44:38Z

* gnu/packages/aux-files/python/sitecustomize.py: normalize sys.prefix to deal with situations where it contains "../", as can happen in relocatable packs. Change-Id: Ibfe13d7c2a14beaa199f599e64bc0b7bfb500fe8 Signed-off-by: Maxim Cournoyer

maint: Merge sanity-check-next.py into sanity-check.py.

2023-04-15T01:01:34Z

* gnu/packages/aux-files/python/sanity-check-next.py: Rename to... * gnu/packages/aux-files/python/sanity-check.py: ... this. * guix/build-system/pyproject.scm (sanity-check.py): Adjust file name. * Makefile.am (AUX_FILES): De-register sanity-check-next.py.

build-system: Add pyproject-build-system.

2022-10-27T17:43:06Z

This is an experimental build system based on python-build-system that implements PEP 517-compliant builds. * doc/guix.texi (Build Systems): Add pyproject-build-system section. * doc/contributing.texi (Python Modules): Mention pyproject.toml and the PYTHON-TOOLCHAIN package, as well as differences to python-build-system. * guix/build-system/pyproject.scm, guix/build/pyproject-build-system.scm, gnu/packages/aux-files/python/sanity-check-next.py, gnu/packages/python-commencement.scm: New files. * Makefile.am (MODULES): Register the new build systems. * gnu/local.mk (GNU_SYSTEM_MODULES): Add python-commencement.scm. * gnu/packages/python.scm (python-sans-pip, python-sans-pip-wrapper): New variables.

build/python: Improve error output in sanity check.

2022-01-10T16:47:03Z

Instead of printing the "str()" representation of the excaption, print the "repr()" representation. This will print the name of the exception and thus ease understanding the actual error. Signed-off-by: Maxim Cournoyer

sitecustomize.py: Honor .pth files.

2022-01-10T16:44:26Z

Fixes . * gnu/packages/aux-files/python/sitecustomize.py: Use site.addsitedirs to add the site directories; this takes care of the .pth files. Make sure the added items still appear before Python's own 'site-packages' directory.

aux-files: sitecustomize: Cleanup and add explanatory comments.

2021-11-11T15:31:32Z

Fixes . * gnu/packages/aux-files/python/sitecustomize.py: Add a comment explaining the general idea, and use sys.prefix instead of sys.executable. (major_minor): Use the unpacking operator (*) to provide the arguments. (site_packages_prefix): Use os.path.join to form the path. (python_site): Likewise. Use sys.prefix instead of sys.executable. (all_sites_raw): Split on os.path.pathsep. (sys.path): Directly splice the result in the list. Suggested-by: Hartmut Goebel Reported-by: Mathieu Othacehe Signed-off-by: Maxim Cournoyer

build-system/python: Handle missing metadata on Python 2.

2021-07-30T13:54:31Z

* gnu/packages/aux-files/python/sanity-check.py: Catch the less specific EnvironmentError rather than FileNotFoundError as the latter is Python 3 only.

build/python: Handle FileNotFoundError exception in sanity-check.py.

2021-02-04T02:56:53Z

This exception was thrown while running the sanity-check on the python-isort package, which doesn't make use of a setuptools-based build system but rather of a PEP 517 compliant one. * gnu/packages/aux-files/python/sanity-check.py: Handle the FileNotFoundError whe attempting to read the 'top_level.txt' metadata file of the package. Remove extraneous 'continue' statement.

build/python: Add a sanity check phase.

2021-02-01T16:53:43Z

Add a new phase validating the usability of installed Python packages. * gnu/packages/aux-files/python/sanity-check.py: New file. * Makefile.am (AUX_FILES): Register it. * guix/build-system/python.scm (sanity-check.py): New variable. (lower): Add the script as an implicit input. * guix/build/python-build-system.scm: Remove trailing #t. (sanity-check): New phase. (%standard-phases): Use it. * tests/builders.scm: (make-python-dummy) (dummy-ok, dummy-dummy-nosetuptools, dummy-fail-requirements) (dummy-fail-import, dummy-fail-console-script): New variables. ("python-build-system: dummy-ok") ("python-build-system: dummy-dummy-nosetuptools") ("python-build-system: dummy-fail-requirements") ("python-build-system: dummy-fail-import") ("python-build-system: dummy-fail-console-script"): Add tests.

gnu: python: Replace PYTHONPATH by GUIX_PYTHONPATH.

2021-02-01T16:53:42Z

Using PYTHONPATH as a mean to discover the Python packages had the following issues: 1. It is not versioned, so different versions of Python would clash if installed in a shared profile. 2. It would interfere with the host Python site on foreign distributions, sometimes preventing a a user to login their GDM session (!). 3. It would take precedence over user installed Python packages installed through pip. 4. It would leak into Python virtualenvs, which are supposed to create isolated Python environments. This changes fixes the above issues by making use of a sitecustomize.py module. The newly introduced GUIX_PYTHONPATH environment variable is read from the environment, filtered for the current Python version of the interpreter, and spliced in 'sys.path' just before Python's own site location, which provides the expected behavior. * gnu/packages/aux-files/python/sitecustomize.py: New file. * Makefile.am: Register it. * gnu/packages/python.scm (customize-site) (guix-pythonpath-search-path): New procedures. (python-2.7)[phases]{install-sitecustomize.py}: New phase. [native-inputs]{sitecustomize.py}: New input. [native-search-paths]: Replace PYTHONPATH with GUIX_PYTHONPATH. (python-3.9)[native-search-paths]: Likewise. [phases]{install-sitecustomize}: Override with correct version. [native-search-paths]: Replace PYTHONPATH with GUIX_PYTHONPATH. * gnu/packages/commencement.scm (python-boot0): [phases]{install-sitecustomize}: Likewise. [native-inputs]{sitecustomize.py}: New input. [native-search-paths]: Replace PYTHONPATH with GUIX_PYTHONPATH. * guix/build/python-build-system.scm (site-packages): Do not add a trailing '/'. squash! gnu: python: Replace PYTHONPATH by GUIX_PYTHONPATH.
