Reported by Andy Wingo <wingo@igalia.com>.
* guix/monads.scm (define-lift) <fallback case>: Add missing #'. Remove
extra formal parameter.
* tests/monads.scm ("lift"): Add test with 'lift1' as a procedure.
* guix/scripts/publish.scm (narinfo-string): Catch 'system-error' around
'load-derivation' call; return BASE-INFO upon ENOENT. This allows us
to return the narinfo even if DERIVER is missing. Before that, the
exception would be uncaught, leading to 500 Internal Error on the
client side.
* guix/import/gem.scm (make-gem-sexp): Properly handle an empty list of
licenses. When rendering a list of licenses, cons 'list onto the front of
the expression.
* tests/gem.scm: New file.
* Makefile.am (SCM_TESTS): Add it.
This significantly reduces churn in the store. It also reduces run time
of 'guix build inkscape -Sd' by ~10%.
* guix/download.scm (url-fetch)[mirror-file]: New variable.
[builder]: Get URL from the "guix download url" env. var. Get the mirrors
from MIRROR-FILE. Pass #:script-name and #:env-vars to 'gexp->derivation'.
* guix/import/pypi.scm (make-pypi-sexp): Factorize license to symbol
conversion code.
(string->license, snake-case, guix-hash-url): Move from here...
* guix/import/utils.scm: ... to here.
(license->symbol): New procedure.
* guix/gexp.scm (lower-object): New procedure.
(lower-inputs, lower-references, gexp->sexp): Use it.
* tests/gexp.scm ("lower-object"): New test.
* doc/guix.texi (G-Expressions): Document it.
* guix/scripts/package.scm (show-help): Add help text for --install-from-file
option.
(%options): Add --install-from-file option.
* tests/guix-package.sh: Test it.
* doc/guix.texi ("invoking guix package"): Document it.
* doc/package-hello.scm: New file.
* doc.am (EXTRA_DIST): Add it.
This removes all I/O, which obviously makes things faster.
* guix/scripts/size.scm (file-size, store-item-exists?): Remove.
(query-path-info*): New procedure.
(file-size*): Rename to...
(file-size): ... this; adjust caller. Use 'query-path-info*' instead of
'file-size'.
On systems with a glibc prior to 2.14, the 'setns' function is not available.
Thanks to Eric Bavier for reporting the issue.
* guix/build/syscalls.scm (setns): Wrap with 'false-if-exception'.
Reported by Eric Dvorsak <eric@dvorsak.fr> on #guix.
* guix/scripts/import/elpa.scm (%default-options): Remove redundant
quote which led to an error if --archive option was not specified.
Based on discussions with Rohan Prinja <rohan.prinja@gmail.com>.
* guix/build/syscalls.scm (<interface>): New record type.
(write-interface, values->interface, unfold-interface-list,
network-interfaces, free-ifaddrs): New procedures.
(ifaddrs): New C struct.
(%struct-ifaddrs-type, %sizeof-ifaddrs): New macros.
* tests/syscalls.scm ("network-interfaces returns one or more interfaces",
"network-interfaces returns \"lo\""): New tests.
* guix/build/syscalls.scm (alignof*, align): New macros.
(write-types, read-types): Use 'align' to compute the actual offset to
read/write a value of TYPE0.
* guix/build/syscalls.scm (PF_PACKET, AF_PACKET): New variables.
(read-socket-address): Make 'index' optional. Return (vector FAMILY) when
FAMILY is neither AF_INET nor AF_INET6.
Previously, before replying to a /nar/* request, 'guix publish' would first
build up the whole nar into memory (as a consequence of
<http://bugs.gnu.org/21093>), which obviously doesn't scale.
* guix/scripts/publish.scm (render-nar): Return STORE-PATH instead of a
procedure that calls 'write-file'.
(sans-content-length): New procedure.
(http-write): For 'x-nix-archive', don't call '%http-write'. Instead, call
'write-file' right from here, using BODY as the file name.
* guix/scripts/publish.scm (%http-write): New variable.
(http-write): New procedure.
(concurrent-http-server): New variable.
(run-publish-server): Use it.
* guix/build/syscalls.scm (read-types): Add RETURN and VALUES parameters.
(define-c-struct): Add WRAP-FIELDS parameter and pass it to 'read-types'.
(sockaddr-in, sockaddr-in6): Add first argument that uses
'make-socket-address'.
(read-socket-address): Remove 'match' on the result of 'read-sockaddr-in'
and 'read-sockaddr-in6'.
