2022-09-24	narinfo: Fix misleading docstring.	Ludovic Courtès
	The misleading docstring had been here from the start, in commit cdea30e061490a521f1e9c66ff870ca98ae5d7e5. * guix/narinfo.scm (valid-narinfo?): Fix docstring.
2021-12-12	narinfo: Do not repeat slash when building nar URLs.	Ludovic Courtès
	* guix/narinfo.scm (narinfo-maker): When one of URLS is relative, do not repeat trailing slash if it's already present in CACHE-URL.
2021-03-21	substitute: Choose compression method based on past CPU usage.	Ludovic Courtès
	This stems from the observation that substitute download can be CPU-bound when high-speed networks are in use: https://lists.gnu.org/archive/html/guix-devel/2020-12/msg00177.html * guix/narinfo.scm (decompresses-faster?): New procedure. (narinfo-best-uri): Add #:fast-decompression?. * guix/scripts/substitute.scm (%prefer-fast-decompression?): New variable. (call-with-cpu-usage-monitoring): New procedure. (with-cpu-usage-monitoring): New macro. (display-narinfo-data, process-substitution): Pass #:fast-decompression? to 'narinfo-best-uri'. (process-substitution): Wrap 'restore-file' call in 'with-cpu-usage-monitoring'. Set '%prefer-fast-decompression?'.
2021-03-05	guix: Split (guix substitutes) from (guix scripts substitute).	Christopher Baines
	This means there's a module for working with substitutes, rather than all the code sitting in the script. The need for this can be seen with the weather and challenge scripts, that now don't have to use code from the substitute script, but can instead use the substitute module. The separation here between the actual functionality of the substitute script and the underlying functionality used both there and elsewhere should make maintenance easier moving forward. This commit just moves code, none of the code should have been changed significantly. * guix/scripts/substitute.scm (%narinfo-cache-directory, %narinfo-ttl, %narinfo-negative-ttl, %narinfo-transient-error-ttl, %unreachable-hosts): Move variables to guix/substitutes.scm. (narinfo-cache-file, cached-narinfo, cache-narinfo!, narinfo-request, read-to-eof, call-with-connection-error-handling, fetch-narinfos, lookup-narinfos, lookup-narinfos/diverse): Move procedures to guix/substitutes.scm. * guix/substitutes.scm: New file. * Makefile.am: Add it. * guix/narinfo.scm: Remove redundant module. * guix/scripts/challenge.scm: Change (guix scripts substitute) to (guix substitutes). * guix/scripts/weather.scm: Change (guix scripts substitute) to (guix substitutes).
2021-02-02	guix: narinfo: Export narinfo-contents.	Christopher Baines
	As this is useful if you want to work with narinfo signatures outside of Guix, in the Guix Data Service for example. * guix/narinfo.scm: Export narinfo-contents.
2021-01-16	guix: Move narinfo code from substitute script to module.	Christopher Baines
	This separation between the code for dealing with narinfos from the code doing that for a purpose should make things clearer, and better support components other that the substitute script in using this code. This is just moving the code around, no code should have been significantly changed. * guix/scripts/substitute.scm (<narinfo>): Move record type to (guix narinfo). (fields->alist, narinfo-hash-algorithm+value, narinfo-hash->sha256, narinfo-signature->canonical-sexp, narinfo-maker, read-narinfo, narinfo-sha256, valid-narinfo?, write-narinfo, narinfo->string, string->narinfo, equivalent-narinfo?, supported-compression?, compresses-better?, narinfo-best-uri): Move procedures to (guix narinfo). (%compression-methods): Move variable to (guix narinfo). * guix/narinfo.scm: New file. * Makefile.am (MODULES): Add it. * po/guix/POTFILES.in: Add 'guix/narinfo.scm'.
