This is a followup to commit 92226a470d.
* guix/packages.scm (patch-and-repack)[build]: Determine if tar supports the
"--sort=name" option using a run-time test. If not supported, generate the
sorted file list with 'find-files' and pass it to tar using "--files-from".
* guix/gexp.scm (%mkdir-p-definition): Remove.
(%utils-module): New variable.
(imported-files, compiled-modules): Have gexp load %UTILS-MODULE
instead of using %MKDIR-P-DEFINITION.
* guix/build/utils.scm (strip-store-file-name): New procedure.
* guix/build/emacs-build-system.scm (store-directory->name-version):
Remove. Update callers to use 'strip-store-file-name'.
* gnu/packages/gcc.scm (make-libstdc++-doc)[arguments]: Use
'strip-store-file-name' instead of 'string-drop'.
* guix/build/gnu-build-system.scm (gnu-build)[elapsed-time]: New
procedure.
Use it, and use (current-time time-monotonic) instead
of (gettimeofday). Show one digit after the comma for the elapsed
time.
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'.
