2022-04-20git-download: Set locale to deal with Unicode in git metadata.Attila Lendvai
Without this the git-fetch GEXP is run in an environment that uses ASCII character encoding when strings are crossing the Guile - C boundary. It means that e.g. tag names that have Unicode chars in them will cause problems, e.g. when walking and deleting the .git directory. An example in the wild: https://github.com/klauspost/pgzip/tags Fixes <https://issues.guix.gnu.org/54893>. * guix/git-download.scm (git-fetch): Call 'setenv' and 'setlocale' to set it to en_US.utf8. * gnu/packages/commencement.scm (glibc-utf8-locales-final): Make public.

2021-06-24gnu: Simplify the use of --with-long-double-128.Chris Marusich
Fixes <https://bugs.gnu.org/48825>. In short, this change adds the hard-coded "--with-long-double-128" configure option in one place and removes it from two other places. This changes and simplifies the use of this option for various architectures that start with the string "powerpc". * gnu/packages/gcc.scm (gcc-configure-flags-for-triplet): Add a clause for targets starting with "powerpc64le-" or "powerpc-" which adds the "--with-long-double-128" option. This causes any package using this procedure to be built using this new option on these architectures. In particular, this affects the gcc package and the gcc-final package, in addition to all the other versions of GCC defined in (gnu packages gcc). * gnu/packages/commencement.scm (gcc-boot0)[#:configure-flags]: Remove the code that adds the "--with-long-double-128" configure option for all architectures starting with "powerpc", since it is now redundant on the architectures where it is needed. The gcc-boot0 package uses (and adds to) the gcc package's configure options. This means that the above change in gcc.scm is sufficient to ensure that the gcc-boot0 package's configure options will include "--with-long-double-128" on powerpc64le and powerpc architectures. Additionally, since the option is apparently not required on the big-endian powerpc64 architecture, this change also has the nice effect of omitting the option in that case. * gnu/packages/cross-base.scm (cross-gcc-arguments)[#:configure-flags]: Remove the code that adds the "--with-long-double-128" configure option for powerpc64le, since it is now redundant. The cross-gcc-arguments procedure uses (and adds to) the configure options of its xgcc argument (a package). This means that regardless of which gcc from gcc.scm is used as the xgcc, the above change in gcc.scm is sufficient to ensure that the cross-gcc-arguments procedure's configure options will include "--with-long-double-128" on the powerpc64le and powerpc architectures.

2021-02-01gnu: python: Replace PYTHONPATH by GUIX_PYTHONPATH.Maxim Cournoyer
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.
