2022-01-27inferior: Move initialization bits away from 'inferior-eval-with-store'....* guix/inferior.scm (port->inferior): In the inferior, define 'cached-store-connection', 'store-protocol-error?', and 'store-protocol-error-message'. (inferior-eval-with-store): Use them. Ludovic Courtès
2022-01-27inferior: Inferior caches store connections....Fixes <https://issues.guix.gnu.org/48007>. Reported by Ricardo Wurmus <rekado@elephly.net>. Previously, at each 'inferior-eval-with-store' call, the inferior would create a new <store-connection> object with empty caches. Consequently, when repeatedly calling 'inferior-package-derivation', we would not benefit from any caching and instead recompute all the derivations for every package. This patch fixes it by caching <store-connection> objects in the inferior. * guix/inferior.scm (port->inferior): Define '%store-table' in the inferior. (inferior-eval-with-store): Cache store connections in %STORE-TABLE. Remove now unneeded 'dynamic-wind' with 'close-port' call. Ludovic Courtès
2022-01-27inferior: Keep the store bridge connected....Previously, each 'inferior-eval-with-store' would lead the inferior to connect to the named socket the parent is listening to. With this change, the connection is established once for all and reused afterwards. * guix/inferior.scm (<inferior>)[bridge-file-name]: Remove. (open-bidirectional-pipe): New procedure. (inferior-pipe): Use it instead of 'open-pipe*' and return two values. (port->inferior): Adjust call to 'inferior'. (open-inferior): Adjust to 'inferior-pipe' changes. (close-inferior): Remove 'inferior-bridge-file-name' handling. (open-store-bridge!): Switch back to 'call-with-temporary-directory'. Define '%bridge-socket' in the inferior, connected to the caller. (proxy): Change first argument to be an inferior. Add 'reponse-port' and call to 'drain-input'. Pass 'reponse-port' to 'select' and use it as a loop termination clause. (inferior-eval-with-store): Remove 'socket' and 'connect' calls from the inferior code, and use '%bridge-socket' instead. Ludovic Courtès
2022-01-27inferior: Create the store proxy listening socket only once....Previously, each 'inferior-eval-with-store' call would have the calling process create a temporary directory with a listening socket in there. Now that listening socket is created once and reused in subsequent calls. * guix/inferior.scm (<inferior>)[bridge-file-name, bridge-socket]: New fields. (port->inferior): Adjust accordingly. (close-inferior): Close 'inferior-bridge-socket' and delete 'inferior-bridge-file-name' if set. (open-store-bridge!, ensure-store-bridge!): New procedures. (inferior-eval-with-store): Use them. Ludovic Courtès
2022-01-17inferior: 'cached-channel-instance' always returns a directory....This is a followup to b1fc98d6b063a117fe2bcc19a60c8b9a48301593. * guix/inferior.scm (cached-channel-instance): When AUTHENTICATE? is false, return (derivation->output-path profile). Ludovic Courtès
2022-01-13inferior: Fix wrong-type-arg error when authentication is disabled....Fixes <https://issues.guix.gnu.org/53230>. Reported by Andrew Tropin <andrew@trop.in>. Fixes a regression introduced in 9f371f23ebfa20f70b3bfd55dc459b683f21ba91. * guix/inferior.scm (cached-channel-instance): Add call to 'derivation->output-path' when AUTHENTICATE? is false. Ludovic Courtès
2021-12-01inferior: 'cached-channel-instance' does not cache unauthenticated instances....The comment saying that caching is fine even when AUTHENTICATE? is false was true in commit 838ac881ec98cb71d4a4e4b20773573f99ecbf25, but it became incorrect in 7cfd789150f448cf5256b88915bae4163cc9db03, which no longer calls 'latest-channel-instances' on cache hits. * guix/inferior.scm (cached-channel-instance): Do not create CACHED when AUTHENTICATE? is false. Ludovic Courtès
2021-08-09inferior: 'cached-channel-instance' no longer calls 'show-what-to-build'....This allows the user of 'cached-channel-instance' to install the build handler of its choice. In particular, it allows "guix time-machine" to install a build notifier with the right options instead of using the defaults that 'cached-channel-instance' would pass to 'show-what-to-build*'. * guix/inferior.scm (cached-channel-instance): Remove call to 'show-what-to-build*'. (inferior-for-channels): Wrap body in 'with-build-handler'. * guix/scripts/time-machine.scm (guix-time-machine): Use 'with-build-handler'. Ludovic Courtès
2021-05-15inferior: Support querying package replacements....I'm looking at this to help with adding support for looking up package replacements to store in the Guix Data Service. * guix/inferior.scm (inferior-package-replacement): New procedure. * tests/inferior.scm ("inferior-package-replacement"): New test. Christopher Baines
2021-03-13inferior: Add <inferior> printer....This avoids printing the whole package table in backtraces and such. * guix/inferior.scm (write-inferior): New procedure. <top level>: Call 'set-record-type-printer!'. Ludovic Courtès
2021-03-10inferior: Use a safe symlink monadic procedure....This is a follow-up of 6ee7e3d26b8f5d2a234518cc2ab1bfeba7cd7c18. * guix/inferior.scm (cached-channel-instance): Introduce "symlink/safe" and use it instead of symlink. Remove the duplicated "file-exists?" call. Mathieu Othacehe
2021-03-10Revert "inferior: Break cached-channel-instance into two procedures."...This reverts commit 7d63b775513e7049047222dbe403a4181f63828d because it raises some concerns, see: https://lists.gnu.org/archive/html/guix-devel/2021-03/msg00124.html. Mathieu Othacehe
2021-03-10inferior: Fix concurrent cached-profile calls....* guix/inferior.scm (cached-profile): Do not create the profile symlink if it already exists. Mathieu Othacehe
2021-03-10inferior: Break cached-channel-instance into two procedures....Break cached-channel-instance into two different procedures: channels->cached-profile and instances->cached-profile operating respectively on channels and channels instances. * guix/inferior.scm (cached-channel-instance): Rename it into ... (cached-profile): ... this new procedure. (channels->cached-profile, instances->cached-profile): New procedures. * guix/scripts/time-machine.scm (guix-time-machine): Adapt accordingly. Mathieu Othacehe
2021-01-29inferior: Speed up 'cached-channel-instance' for cache hits....That way a command like: guix time-machine --commit=5aeee07cc9 -- describe goes from 3.4s to 0.5s on a cache hit, even slightly less when passing the full commit ID. * guix/inferior.scm (channel-full-commit): New procedure. (cached-channel-instance): Remove 'instances' top-level variable. Add 'commits' and use it for 'key'. Move 'latest-channel-instances' call to the cache miss case. Ludovic Courtès
2021-01-28guix: Fix typo....* guix/inferior.scm (inferior-available-packages): Remove extra word in docstring. Ricardo Wurmus
2021-01-27inferior: Memoize entries in 'inferior-package->manifest-entry'....Fixes a performance issue as reported by Ricardo Wurmus in <https://bugs.gnu.org/46100>. * guix/inferior.scm (inferior-package->manifest-entry): Remove #:parent parameter. [cache]: New variable. [memoized]: New macro. [loop]: New procedure. Ludovic Courtès
2020-12-19maint: Require Guile >= 2.2.6....* configure.ac: For Guile 2.2, require 2.2.6 or later. * guix/gexp.scm (define-syntax-parameter-once): Remove. Use 'define-syntax-parameter' instead. * guix/mnoads.scm: Likewise. * guix/inferior.scm (proxy)[select*]: Remove. * guix/scripts/publish.scm <top level>: Remove replacement for (@@ (web http) read-header-line). * guix/store/deduplication.scm (counting-wrapper-port): Remove. (nar-sha256): Call 'port-position' on PORT to compute SIZE. Ludovic Courtès
2020-07-25utils: Move <location> and '&error-location' to (guix diagnostics)....* guix/utils.scm (<location>, source-properties->location) (location->source-properties, &error-location): Move to... * guix/diagnostics.scm: ... here. * gnu.scm: Adjust imports accordingly. * gnu/machine.scm: Likewise. * gnu/system.scm: Likewise. * gnu/tests.scm: Likewise. * guix/inferior.scm: Likewise. * tests/channels.scm: Likewise. * tests/packages.scm: Likewise. Ludovic Courtès
2020-06-16time-machine: Add '--disable-authentication'....* guix/inferior.scm (cached-channel-instance): Add #:authenticate? and pass it to 'latest-channel-instances'. * guix/scripts/time-machine.scm (show-help, %options): Add '--disable-authentication'. (%default-options): Add 'authenticate-channels?'. (guix-time-machine): Honor it. Ludovic Courtès
2020-03-19inferior: '&inferior-exception' includes a stack trace....* guix/inferior.scm (port->inferior): Bump protocol to (0 1 1). (&inferior-exception)[stack]: New field. (read-repl-response): Recognize 'exception' form for protocol (0 1 1). * tests/inferior.scm ("&inferior-exception"): Check the value returned by 'inferior-exception-stack'. Ludovic Courtès
2020-03-19inferior: Adjust to protocol (0 1)....* guix/inferior.scm (port->inferior): For protocol (0 x ...), where x >= 1, send the (() repl-version ...) form. Ludovic Courtès
2020-03-12inferior: Distinguish inferior exceptions....This avoids ambiguities when looking at a backtrace where the exception was actually thrown by an inferior in a very different context. * guix/inferior.scm (&inferior-exception): New condition type. (read-repl-response): Add optional 'inferior' parameter. Raise '&inferior-exception' instead of rethrowing to KEY when receiving an 'exception' message. (read-inferior-response): Pass INFERIOR to 'read-repl-response'. * tests/inferior.scm ("&inferior-exception"): New test. Ludovic Courtès
2020-01-15More module autoload adjustments....This is a followup to 7a0836cffdfe3ab9ee899602f218277646959144. * guix/scripts/package.scm: Adjust binding list of the (guix store roots) autoload. * guix/inferior.scm: Adjust binding list of the (guix cache) autoload. Ludovic Courtès
2019-12-29inferior: Add 'inferior-package-provenance'....* guix/inferior.scm (inferior-package-provenance): New procedure. Ludovic Courtès
2019-11-15inferior: 'cached-channel-instance' takes an open store connection....* guix/inferior.scm (cached-channel-instance): Take an explicit 'store' argument. (inferior-for-channels): Wrap call to 'cached-channel-instance' in 'with-store'. * guix/time-machine.scm (guix-time-machine): Wrap call to 'cached-channel-instance' in 'with-store'. Signed-off-by: Ludovic Courtès <ludo@gnu.org> Konrad Hinsen
2019-11-15Add 'guix time-machine'....* guix/scripts/time-machine.scm: New file. * Makefile.am: (MODULES): Add it. * guix/scripts/pull.scm (channel-list): Export. * guix/inferior.scm (cached-channel-instance): New procedure. (inferior-for-channels): Use it. * doc/guix.texi (Invoking guix time-machine): New section. (Channels): Cross-reference it. Signed-off-by: Ludovic Courtès <ludo@gnu.org> Konrad Hinsen
2019-10-15inferior: Set the error port when using older Guix versions....This makes the behaviour more consistent. * guix/inferior.scm (inferior-pipe): Wrap the second open-pipe* call with with-error-to-port, to match the first call to open-pipe*. Christopher Baines
2019-10-15inferior: Allow controlling the inferior error port....Previously, stderr for the inferior process would always be sent to /dev/null because the current-output-port when the process is launched is a void port. This change means that it's possible to pass in a different port to use. * guix/inferior.scm (inferior-pipe): Take the error-port as an argument. (open-inferior): Add new error-port keyword argument, with a default of (%make-void-port "w"). Christopher Baines
2019-10-01inferior: Change to use the (guix repl) module....Rather than (guix scripts repl), from which the machine-repl procedure was removed in [1]. 1: 92a4087bf4862d5ba9b77111eba3c68c2a1c4679 * guix/inferior.scm (inferior-pipe): Load (guix repl) rather than (guix scripts repl). Christopher Baines
2019-09-23inferior: Fix typo....* guix/inferior: Fix spelling of "specifications". Vagrant Cascadian
2019-09-21inferior: Propagate '&store-protocol-error' error conditions....Until now '&store-protocol-error' conditions raised in the inferior would not be correctly propagated because SRFI-35 records lack a read syntax. Reported at <https://bugs.gnu.org/37449> by Carl Dong <contact@carldong.me>. * guix/inferior.scm (port->inferior): Import (srfi srfi-34) in the inferior. (inferior-eval-with-store): Define 'error?' and 'error-message'. Wrap call to PROC in 'guard'. Check the response of INFERIOR for a 'store-protocol-error' or a 'result' tag. * tests/inferior.scm ("inferior-eval-with-store, &store-protocol-error"): New test. Ludovic Courtès
2019-07-04inferior: Add 'read-repl-response'....* guix/inferior.scm (read-repl-response): New procedure. (read-inferior-response): Use it. Ludovic Courtès
2019-03-08channels: Do not fail when the inferior lacks 'guix repl'....Fixes <https://bugs.gnu.org/34637>. Reported by Martin Flack <martin.flack@gmail.com>. Previously we'd fail to build the package cache for old versions of Guix that lack 'guix repl'. Now we simply ignore the issue and keep going without a cache. * guix/inferior.scm (gexp->derivation-in-inferior): Add #:silent-failure? and honor it. [drop-extra-keyword]: New procedure. Use it. * guix/channels.scm (package-cache-file): Pass #:silent-failure? #t. Ludovic Courtès
2019-02-12inferior: Add 'inferior-available-packages'....* guix/inferior.scm (inferior-available-packages): New procedure. * tests/inferior.scm ("inferior-available-packages"): New test. Ludovic Courtès
2019-01-21store: Rename <nix-server> to <store-connection>....* guix/store.scm (<nix-server>): Rename to... (<store-connection>): ... this. Adjust users accordingly. (nix-server?, nix-server-major-version) (nix-server-minor-version, nix-server-socket) (nix-server-version): Define as deprecated aliases. * guix/inferior.scm: Adjust accordingly. * guix/ssh.scm: Likewise. Ludovic Courtès
2019-01-20inferior: 'gexp->derivation-in-inferior' honors EXP's load path....Previously the imported modules and extensions of EXP would be missing from the load path of 'guix repl'. * guix/inferior.scm (gexp->derivation-in-inferior)[script]: New variable. [trampoline]: Write (primitive-load #$script) to PIPE. Add #$output. * tests/channels.scm ("channel-instances->manifest")[depends?]: Check for requisites rather than direct references. Adjust callers accordingly. Ludovic Courtès
2019-01-15inferior: Add 'gexp->derivation-in-inferior'....* guix/inferior.scm (gexp->derivation-in-inferior): New procedure. Ludovic Courtès
2019-01-09Remove most uses of the _IO*F constants....These constants, for use with 'setvbuf', were deprecated in Guile 2.2 and disappeared in Guile 3.0. Here we keep these constants in build-side code where removing them is not feasible. * guix/build/download-nar.scm (download-nar): Adjust 'setvbuf' calls to the Guile 2.2+ API. * guix/build/download.scm (open-socket-for-uri): Likewise. (open-connection-for-uri, url-fetch): Likewise. * guix/build/make-bootstrap.scm (make-stripped-libc): Likewise. * guix/build/union.scm (setvbuf) [guile-2.0]: New conditional wrapper.

Ludovic Courtès
2019-01-09maint: Remove 'cond-expand' forms for Guile 2.0....Note: Leave 'cond-expand' forms used in the build-side modules that can run on %BOOTSTRAP-GUILE, which is currently Guile 2.0. * guix/build/compile.scm: Move 'use-modules' clause from 'cond-expand' to 'define-module' form. (%default-optimizations): Remove 'cond-expand'. * guix/build/download.scm (tls-wrap): Remove 'cond-expand'. * guix/build/syscalls.scm: Remove 'cond-expand' form around '%set-automatic-finalization-enabled?!' and 'without-automatic-finalization'. * guix/inferior.scm (port->inferior): Remove 'cond-expand'. * guix/scripts/pack.scm (wrapped-package)[build]: Remove 'cond-expand'. * guix/status.scm (build-event-output-port): Remove 'cond-expand'. * guix/store.scm (open-inet-socket): Remove 'cond-expand'. * guix/ui.scm (install-locale): Remove 'cond-expand'. * tests/status.scm ("current-build-output-port, UTF-8 + garbage"): Remove 'cond-expand'. * tests/store.scm ("current-build-output-port, UTF-8 + garbage"): Remove 'cond-expand'.
