This mostly reverts 17af5d51de.
Suggested by Andy Wingo <wingo@igalia.com>.
* guix/ssh.scm (remote-daemon-channel)[redirect]: Remove 'read!' FFI
hack. Use buffered ports.
This fixes a regression in 'retrieve-files*' introduced in
896fec476f, whereby (guix scripts offload)
would not read the initial sexp now sent by the remote host via
'store-export-channel'. This would effectively prevent file retrieval
entirely when offloading.
* guix/ssh.scm (retrieve-files*): New procedure, like former
'retrieve-files' but with an extra #:import parameter.
(retrieve-files): Rewrite in terms of 'retrieve-files*'.
(file-retrieval-port): Make private.
* guix/scripts/offload.scm (transfer-and-offload): Pass #:import to
'retrieve-files*'.
(retrieve-files*): Remove.
Previously the redirect code could end up exiting prematurely because of
an uninteresting "exceptional condition" on the socket (info "(libc)
Waiting for I/O").
* guix/ssh.scm (remote-daemon-channel): Pass the empty list as the third
argument to 'select'. It was a mistake to pass a non-empty list there
in the first place.
Previously 'process-stderr' would always pass a bytevector of MAX-LEN to
then daemon in the %stderr-read case (i.e., 'import-paths'), instead of
LEN (where LEN <= MAX-LEN).
In practice the extra bytes didn't cause a protocol violation or
anything because they happen at the end of the stream, which typically
contains the canonical sexp of the signature, and the extra zeros were
just ignored.
* guix/serialization.scm (write-bytevector): Add optional 'l' parameter
and honor it.
* guix/store.scm (process-stderr): Pass LEN to 'write-bytevector'.
This works around <https://bugs.gnu.org/30066> and noticeably improves
performance when using GUIX_DAEMON_SOCKET=ssh://HOST (the redirect code
was transferring data to guix-daemon one byte at a time!).
* guix/ssh.scm (remote-daemon-channel)[redirect]: Define 'read!' and use
it instead of 'get-bytevector-some'.
This was harmless but non-compliant and unnecessary.
* guix/scripts/publish.scm <top level>: Rename "Guix-Nar-Compression" to
"X-Nar-Compression" as should have always been.
(render-nar, nar-response-port): Adjust accordingly.
(strip-headers): New procedure.
(sans-content-length, with-content-length): Use it.
Reported by Fis Trivial <ybbs.daans@hotmail.com>.
Fixes <https://bugs.gnu.org/28987>.
* guix/import/crate.scm (crate-fetch): Check whether the "license" info
is present.
This adjusts the workaround for <http://bugs.gnu.org/21093> so that it's
not limited to a single content-type.
* guix/scripts/publish.scm (render-nar/cached): Add the 'x-raw-file'
header on the response.
(render-content-addressed-file): Likewise.
(with-content-length): Remove the 'x-raw-file' header.
(http-write): Instead of dispatching on 'application/octet-stream',
check whether 'x-raw-file' is set to determine whether to spawn a
thread.
'guix copy --from' now reports messages much more useful than "failed to
retrieve files".
* guix/ssh.scm (store-export-channel)[export]: Wrap 'use-modules' in
'catch' and 'with-store' in 'guard'. Check for invalid items. Write a
status sexp on stdout.
(raise-error): New macro.
(retrieve-files): Read the initial status sexp and report errors
accordingly.
This saves 18 bytes on each 404 narinfo response.
* guix/scripts/publish.scm (render-narinfo): Pass #:phrase to
'not-found'.
(render-narinfo/cached): Likewise.
* guix/scripts/build.scm (numeric-extension?, tarball-base-name): New
procedures, formerly in 'package-with-source'.
(transform-package-source)[new-sources]: Look for '=' in URI. Each
element of the list of now a (PKG VERSION SOURCE) tuple.
Pass VERSION to 'package-with-source'.
(package-with-source): Add 'version' parameter and honor it.
* tests/scripts-build.scm ("options->transformation, with-source, PKG=URI")
("options->transformation, with-source, PKG@VER=URI"): New tests.
* doc/guix.texi (Package Transformation Options): Document the new
forms.
This would crash 'guix refresh -u' with source URLs ending in
"…/v1.2.3".
* guix/upstream.scm (package-update): Be stricter when determining
ARCHIVE-TYPE.
Fixes <https://bugs.gnu.org/29761>.
Reported by Martin Castillo <castilma@uni-bremen.de>.
* guix/scripts/gc.scm (argument->verify-options): New procedure.
(%options) ["verify"]: Adjust to use it.
* tests/guix-gc.sh: Add test.
Fixes 'guix pull'.
Reported by ofosos on #guix.
* guix/man-db.scm: Use 'module-autoload!' instead of 'module-use!'.
so that (gdbm) is not loaded until we need it.
Fixes <https://bugs.gnu.org/29654>.
Reported by Ruud van Asseldonk <dev+guix@veniogames.com>.
This also speeds up database creation compared to "man-db
--create" (less than half the time, on a warm cache, for 19k pages.)
* guix/man-db.scm: New file.
* Makefile.am (MODULES_NOT_COMPILED): Add it.
* guix/profiles.scm (manual-database): Rewrite to use (guix man-db).
* guix/scripts/offload.scm (check-machine-status): New procedure.
(guix-offload): Call it when the argument is "status".
* doc/guix.texi (Daemon Offload Setup): Document it.
* guix/scripts/system.scm (show-help): Add expression option.
(%options): Ditto.
(guix-system): Allow commands taking a file as an argument to use an
expression instead.
(process-action): Read operating-system from expression or file.
* doc/guix.texi (Invoking guix system): Introduce the expression option.
* gnu/bootloader/extlinux.scm (install-extlinux): Factorize bootloader
writing in a new procedure write-file-on-device defined in (gnu build
bootloader).
* gnu/build/bootloader.scm: New file.
* gnu/local.mk (GNU_SYSTEM_MODULES): Add new file.
* gnu/system/vm.scm (qemu-img): Adapt to import and use (gnu build bootloader)
module during derivation building.
* gnu/scripts/system.scm (bootloader-installer-derivation): Ditto.
This reduces max RSS from 1.3G to 1.0G.
* guix/derivations.scm (invalidate-derivation-caches!): New procedure.
* build-aux/hydra/gnu-system.scm (hydra-jobs): Use it. Add 'format'
call.
This has little or no run-time impact and slightly reduces the memory
footprint.
* guix/derivations.scm (derivation-hash): Replace 'mlambda' with
'lambda'.
* guix/memoization.scm (<cache>): New record type.
(define-lookup-procedure, define-update-procedure): New macros.
(cache-ref, cacheq-ref, cache-set!, cacheq-set!): New procedures.
(cached/mv, cachedq/mv, cached, cachedq): Use them instead of 'hash-ref'
and 'hash-set!'.
(%make-hash-table*): When 'profiled?' returns true, return a <cache>
object.
(define-cache-procedure): Adjust to show cache lookups and hits.
* guix/memoization.scm (%memoization-tables): New variable.
(%make-hash-table*, show-memoization-tables): New procedures.
(make-hash-table*): New macro.
Add top-level call to 'register-profiling-hook!'.
(memoize): Adjust to pass the resulting procedure to
'make-hash-table*'.
(%mlambda): Likewise.
Fixes <https://bugs.gnu.org/29255>.
Reported by Ben Sturmfels <ben@sturm.com.au>.
* guix/ui.scm (display-collision-resolution-hint): New procedure.
(call-with-error-handling): Call it upon '&profile-collistion-error'.
* guix/scripts/lint.scm (check-vulnerabilities): Also check for CVEs
listed as mitigated in the package properties.
* tests/lint.scm ("cve: known safe from vulnerability"): New test.
