2021-05-20	scripts: challenge: Fix regression.	Mathieu Othacehe
	This is a follow-up of 3cde5231aa78aa5e31b27888cd78ee0b250a7a1c that fixes the challenge test. When dealing with uncompressed NAR, the file size is false. Propagate it to progress-reporter/file as it used to be the case. * guix/scripts/challenge.scm (call-with-nar): Accept false size.
2021-05-13	challenge: Be defensive in the size passed to the progress reporter.	Ludovic Courtès
	Possibly fixes <https://bugs.gnu.org/48045>. Reported by Bone Baboon <bone.baboon@disroot.org>. * guix/scripts/challenge.scm (call-with-nar): Rename second value returned by 'http-fetch' to match reality. Change second argument to 'progress-reporter/file'.
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).
2021-01-16	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'.
