2022-02-07guix: Restore profile hook for TeX Live font maps.Ricardo Wurmus
Long ago we had a profile hook, called “texlive-configuration”, which would operate on the texlive-* packages that have actually been installed in the profile, build a union directory, and then install a texmf.cnf file that declared the prefix of the TeX Live tree to be the union directory. It then generated font maps based on the fonts that had actually been installed. This approach had multiple disadvantages, the worst of which was that you could only really have one TeX Live tree. Commit 04a0b1e09abce99857e7930336421ca6d15ae630 addressed this, where texmf.cnf was modified *once* and for all in texlive-bin to reference the GUIX_TEXMF variable to determine the root of the tree. This made much of “texlive-configuration” obsolete, because we didn’t need to have any union directories at all, because we had no need for a customized per-profile variant of texmf.cnf. Unfortunately, with the loss of the profile hook we would no longer build font maps. This patch resurrects the profile hook: we’re again generating font maps (such as pdftex.map) based on the contents of the profile. * gnu/packages/tex.scm (texlive-default-updmap.cfg): New variable. * guix/profiles.scm (texlive-configuration): Rename this... (texlive-font-maps): ...to this; update to run updmap-sys on the contents of the profile to generate only font maps.

It has been reported in IRC, that directories may show up multiple times in subdirs.el, probably a result of propagation.

When running: guix environment --ad-hoc gnome --no-grafts --search-paths this reduces wall-clock time by ~5%. The number of object cache lookups goes down from 96K to 89K. (Note that 'gnome' is an interesting example because it has many propagated inputs, which themselves have propagated inputs too, which would lead to a long input list and a long manifest in the 'profile-derivation' gexp.) * guix/profiles.scm (profile-derivation)[inputs, search-paths]: Remove.

2021-01-29gnu: texlive-bin: Enable the use of multiple TeX Live trees.Maxim Cournoyer
Attempting to compose multiple TeX Live trees (such as can happen when using a texlive-union generated package) proved problematic; only the texmf.cnf configuration file from the union would be honored, causing other TeX Live components to be ignored. This change does away with TeX Live unions, instead relying on the default texmf.cnf configuration file provided by the texlive-bin package to honor individual TeX Live trees referred to via the newly introduced GUIX_TEXMF variable, and replacing the texlive-union procedure by texlive-updmap.cfg, to explicit that generating the fonts map configuration is now its sole purpose. * gnu/packages/tex.scm (texlive-bin)[phases]{customize-texmf}: New phase. {postint}: Move the patching of the texmf.cnf file to the new above phase. Patch the updmap.pl script to find its Perl modules. [native-search-paths]: Rename the TEXMF variable to GUIX_TEXMF.

2020-08-25linux-libre: Support module compression.Mathieu Othacehe
This commit adds support for GZIP compression for linux-libre kernel modules. The initrd modules are kept uncompressed as the initrd is already compressed as a whole. The linux-libre kernel also supports XZ compression, but as Guix does not have any available bindings for now, and the compression time is far more significant, GZIP seems to be a better option. * gnu/build/linux-modules.scm (modinfo-section-contents): Use 'call-with-gzip-input-port' to read from a module file using '.gz' extension, (strip-extension): new procedure, (dot-ko): adapt to support compression, (ensure-dot-ko): ditto, (file-name->module-name): ditto, (find-module-file): ditto, (load-linux-module*): ditto, (module-name->file-name/guess): ditto, (module-name-lookup): ditto, (write-module-name-database): ditto, (write-module-alias-database): ditto, (write-module-device-database): ditto. * gnu/installer.scm (installer-program): Add "guile-zlib" to the extensions. * gnu/machine/ssh.scm (machine-check-initrd-modules): Ditto. * gnu/services.scm (activation-script): Ditto. * gnu/services/base.scm (default-serial-port): Ditto, (agetty-shepherd-service): ditto, (udev-service-type): ditto. * gnu/system/image.scm (gcrypt-sqlite3&co): Ditto. * gnu/system/linux-initrd.scm (flat-linux-module-directory): Add "guile-zlib" to the extensions and make sure that the initrd only contains uncompressed module files. * gnu/system/shadow.scm (account-shepherd-service): Add "guile-zlib" to the extensions. * guix/profiles.scm (linux-module-database): Ditto.
