Fixes <https://bugs.gnu.org/29358>.
Reported by Marius Bakke <mbakke@fastmail.com>.
* guix/ui.scm (known-variable-definition): Add 'visited' set to guard
against cycles on 2.0.
Suggested by Ricardo Wurmus.
Works around <https://bugs.gnu.org/28295>.
* guix/ui.scm (report-load-error): Add case for 'read-error'.
* tests/guix-system.sh: Test missing-closing-paren errors.
* guix/store.scm (%rpc-calls): New variable.
(show-rpc-profile, record-operation): New procedures.
(operation): Add call to 'record-operation'.
* guix/ui.scm (run-guix-command): Wrap COMMAND-MAIN in 'dynamic-wind'.
Run EXIT-HOOK.
* guix/derivations.scm (derivation-prerequisites-to-build): Rename
#:substitutable? to #:substitutable-info.
[derivation-substitutable?]: Rename to...
[derivation-substitutable-info]: ... this. Return a list of <substitutable>.
Second return value is now a list of <substitutable> instead of a list
of strings.
* guix/ui.scm (show-what-to-build)[substitutable?]: Rename to...
[substitutable-info]: ... this.
Adjust to new 'derivation-prerequisites-to-build' return value type.
* tests/derivations.scm ("derivation-prerequisites-to-build and
substitutes"): Adjust.
("derivation-prerequisites-to-build and substitutes, local build"):
Likewise.
This fixes runs of 'guix package' and 'guix system' tests in
environments where $HOME is read-only.
* guix/ui.scm (config-directory): Add #:ensure? parameter and honor it.
* guix/scripts.scm (warn-about-old-distro): Pass #:ensure? #f to
'config-directory'.
* guix/ui.scm (package-field-string): New procedure.
(package-description-string): Use it.
(package-synopsis-string): New procedure.
(package->recutils): Use it.
* guix/scripts/lint.scm (check-synopsis-style)[check-texinfo-markup]:
New procedure. Use it in checks.
* tests/lint.scm: Test it.
* gnu/packages/perl.scm (perl-try-tiny)[synopsis]: Adjust for the
Texinfo markup.
* guix/ui.scm (right-arrow): Call 'set-port-encoding!' to set PORT's
encoding; remove use of 'with-fluids'. This is for compatibility with
Guile 2.2 where the encoding of string ports is not influenced by
%DEFAULT-PORT-ENCODING.
* tests/ui.scm ("show-manifest-transaction"): Likewise.
* guix/ui.scm (fill-paragraph): Don't use '_' as a pattern variable
since that is shadowed by the top-level '_' binding on Guile 2.2.
(show-manifest-transaction): Likewise.
* guix/ui.scm (augmented-system-error-handler): New procedure.
(error-reporting-wrapper): New macro.
(symlink, copy-file): Define using 'error-reporting-wrapper'.
Suggested by John Darrington <john@darrington.wattle.id.au>.
* guix/ui.scm (show-version-and-exit): Make "Copyright (C) 2017"
untranslatable, except "(C)" itself, like Gnulib's version-etc does.
* guix/ui.scm (display-profile-content-diff): New variable.
* guix/scripts/package.scm (process-query): Use display-profile-content-diff.
In collaboration with Benz Schenk.
This avoids loads of needless 'stat' calls due to the default 'relative
setting and the 'canonicalize-path' calls it leads to. This was
especially visible when 'guix substitute' access files in
/var/guix/substitute/cache.
* guix/ui.scm (run-guix-command): Set %FILE-PORT-NAME-CANONICALIZATION
to #f.
Suggested by Jookia.
* guix/derivations.scm (&file-search-error): New error condition.
(search-path*): Raise it when 'search-path' returns #f.
* guix/gexp.scm (search-path*): Remove.
* guix/ui.scm (call-with-error-handling): Add case for
'file-search-error?'.
* tests/derivations.scm ("build-expression->derivation and invalid
module name"): New test.
This provides the ability to use numbers in package names.
Fixes <http://bugs.gnu.org/19219>.
* guix/utils.scm (package-name->name+version): New procedure.
* gnu/packages.scm (%find-package): Add a FALLBACK? keyword argument.
Use the previous method when no package is found.
(specification->package+output, specification->package): Adapt
documentation to new syntax.
* doc/guix.texi (Invoking guix package, Invoking guix import): Likewise.
* guix/ui.scm (package-specification->name+version+output): Likewise.
* guix/scripts/import/hackage.scm (show-help): Likewise.
* tests/guix-build.sh: Adapt to new syntax.
* tests/guix-lint.sh: Likewise.
* tests/guix-package.sh: Likewise.
