2021-01-21repl: Fix exception handling for interpreted code.Ludovic Courtès
The 'stack' variable could be #f when code is interpreted, which in practice happens when running in "legacy" mode--i.e., when 'open-inferior' invokes "guile" instead of "guix repl". * guix/repl.scm (send-repl-response)[handle-exception]: Check whether STACK is true before passing it to 'stack->frames'. * tests/inferior.scm ("&inferior-exception, legacy mode"): New test.

2021-01-16guix: Move narinfo code from substitute script to module.Christopher Baines
This separation between the code for dealing with narinfos from the code doing that for a purpose should make things clearer, and better support components other that the substitute script in using this code. This is just moving the code around, no code should have been significantly changed. * guix/scripts/substitute.scm (<narinfo>): Move record type to (guix narinfo). (fields->alist, narinfo-hash-algorithm+value, narinfo-hash->sha256, narinfo-signature->canonical-sexp, narinfo-maker, read-narinfo, narinfo-sha256, valid-narinfo?, write-narinfo, narinfo->string, string->narinfo, equivalent-narinfo?, supported-compression?, compresses-better?, narinfo-best-uri): Move procedures to (guix narinfo).

2020-12-19daemon: Let 'guix substitute' perform hash checks.Ludovic Courtès
This way, the hash of the store item can be computed as it is restored, thereby avoiding an additional file tree traversal ('hashPath' call) later on in the daemon. Consequently, it should reduce latency between subsequent substitute downloads. This is a followup to 5ff521452b9ec2aae9ed8e4bb7bdc250a581f203. * guix/scripts/substitute.scm (narinfo-hash-algorithm+value): New procedure. (process-substitution): Wrap INPUT into a hash input port, 'hashed', and read from it. Compare the actual and expected hashes, and print a "hash-mismatch" status line when they differ. When they match, print not just "success" but also the nar hash and size. * nix/libstore/build.cc (class SubstitutionGoal)[expectedHashStr]: Remove. (SubstitutionGoal::finished): Tokenize 'status'. Parse it and handle "success" and "hash-mismatch" accordingly. Call 'hashPath' only when the returned hash is not SHA256.

This avoids repeated (mkdir-p "/gnu/store/.links") calls when deduplicating lots of files. * guix/store/deduplication.scm (deduplicate): Remove initial call to 'mkdir-p'. Add ENOENT case in 'link' exception handler. Reindent. * tests/store-deduplication.scm ("deduplicate, ENOSPC"): Check for (<= links 4) to account for the initial 'link' call.
2020-12-15database: Remove 'register-path'.Ludovic Courtès
* guix/store/database.scm (register-path): Remove. * tests/store-database.scm ("register-path"): Rename to... ("register-items"): ... this, and use 'register-items' instead of 'register-path'. ("register-path, directory"): Rename to... ("register-items, directory"): ... this, and use 'register-items' instead of 'register-path'. ("register-path with unregistered references"): Rename to... ("sqlite-register with unregistered references"): ... this.
2020-12-15database: Remove #:deduplicate? and #:reset-timestamps? from 'register-path'.Ludovic Courtès

2020-12-15store-copy: 'populate-store' can optionally deduplicate files.Ludovic Courtès
Until now deduplication was performed as an additional pass after copying files, which involve re-traversing all the files that had just been copied. * guix/store/deduplication.scm (copy-file/deduplicate): New procedure. * tests/store-deduplication.scm ("copy-file/deduplicate"): New test. * guix/build/store-copy.scm (populate-store): Add #:deduplicate? parameter and honor it. * tests/gexp.scm ("gexp->derivation, store copy"): Pass #:deduplicate? #f to 'populate-store'. * gnu/build/image.scm (initialize-root-partition): Pass #:deduplicate? to 'populate-store'. Pass #:deduplicate? #f to 'register-closure'. * gnu/build/vm.scm (root-partition-initializer): Likewise. * gnu/build/install.scm (populate-single-profile-directory): Pass #:deduplicate? #f to 'populate-store'. * gnu/build/linux-initrd.scm (build-initrd): Likewise. * guix/scripts/pack.scm (self-contained-tarball)[import-module?]: New procedure. [build]: Pass it as an argument to 'source-module-closure'. * guix/scripts/pack.scm (squashfs-image)[build]: Wrap in 'with-extensions'. * gnu/system/linux-initrd.scm (expression->initrd)[import-module?]: New procedure. [builder]: Pass it to 'source-module-closure'. * gnu/system/install.scm (cow-store-service-type)[import-module?]: New procedure. Pass it to 'source-module-closure'.
2020-12-15store-copy: 'populate-store' resets timestamps.Ludovic Courtès
Until now, 'populate-store' would reset permissions but not timestamps, so callers would resort to going through an extra directory traversal to reset timestamps. * guix/build/store-copy.scm (reset-permissions): Remove. (copy-recursively): New procedure. (populate-store): Pass #:keep-permissions? to 'copy-recursively'. Remove call to 'reset-permissions'. * tests/gexp.scm ("gexp->derivation, store copy"): In BUILD-DRV, check whether 'populate-store' canonicalizes permissions and timestamps. * gnu/build/image.scm (initialize-root-partition): Pass #:reset-timestamps? #f to 'register-closure'. * gnu/build/vm.scm (root-partition-initializer): Likewise.
2020-12-15nar: Deduplicate files right as they are restored.Ludovic Courtès
This avoids having to traverse and re-read the files that we have just restored, thereby reducing I/O. * guix/serialization.scm (dump-file): New procedure. (restore-file): Add #:dump-file parameter and honor it. * guix/store/deduplication.scm (tee, dump-file/deduplicate): New procedures. * guix/nar.scm (restore-one-item): Pass #:dump-file to 'restore-file'. (finalize-store-file): Pass #:deduplicate? #f to 'register-items'. * tests/nar.scm <top level>: Call 'setenv' to set "NIX_STORE".
2020-12-15serialization: 'restore-file' sets canonical timestamp and permissions.Ludovic Courtès
* guix/serialization.scm (restore-file): Set the permissions and mtime of FILE. * guix/nar.scm (finalize-store-file): Pass #:reset-timestamps? #f to 'register-items'. * tests/nar.scm (rm-rf): Add 'chmod' calls to ensure files are writable. ("write-file + restore-file with symlinks"): Ensure every file in OUTPUT passes 'canonical-file?'. * tests/guix-archive.sh: Run "chmod -R +w" before "rm -rf".
2020-12-15serialization: 'fold-archive' notifies about directory processing completion.Ludovic Courtès
* guix/serialization.scm (fold-archive): Call PROC with a 'directory-complete tag when done with a directory. (restore-file): Handle it. * guix/scripts/archive.scm (list-contents): Likewise. * guix/scripts/challenge.scm (archive-contents): Likewise. * tests/nar.scm ("write-file-tree + fold-archive"): Adjust accordingly.

This is a followup to a8dccd4bdc1e58219d4ba08fe1649bf0b8325f44, which broke the test. * guix/import/opam.scm (get-opam-repository): Prevent inlining. * tests/opam.scm ("opam->guix-package"): Mock 'get-opam-repository'.
2020-12-08daemon: Run 'guix substitute --substitute' as an agent.Ludovic Courtès
This avoids spawning one substitute process per substitution. * nix/libstore/build.cc (class Worker)[substituter]: New field. [outPipe, logPipe, pid]: Remove. (class SubstitutionGoal)[expectedHashStr, status, substituter]: New fields. (SubstitutionGoal::timedOut): Adjust to check 'substituter'. (SubstitutionGoal::tryToRun): Remove references to 'outPipe' and 'logPipe'. Run "guix substitute --substitute" as an 'Agent'. Send the request with 'writeLine'. (SubstitutionGoal::finished): Likewise. (SubstitutionGoal::handleChildOutput): Change to fill in 'expectedHashStr' and 'status'. (SubstitutionGoal::handleEOF): Call 'wakeUp' unconditionally. (SubstitutionGoal::~SubstitutionGoal): Adjust to check 'substituter'. * guix/scripts/substitute.scm (process-substitution): Write "success\n" to stdout upon success. (%error-to-file-descriptor-4?): New variable. (guix-substitute): Set 'current-error-port' to file descriptor 4 unless (%error-to-file-descriptor-4?) is false. Remove "--substitute" arguments.

2020-12-02import: crate: Use existing package satisfying semver requirement.Hartmut Goebel
If a package satisfying the dependency's semver requirement already exists, use it. Prior to this change the highest version matching the semver requirement was used (and imported in case it was not defined as package already). When resolving a dependency (now done in `sort-map-dependencies`), first search for a package matching the semver requirement and only if this fails reach out for a crate. * guix/import/crate.scm (crate->guix-package)[find-package-version]: New function. [dependency-name+version]: New function. [sort-map-dependencies]: Use it instead of lambda function. * tests/crate.scm (test-doctool-crate, test-doctool-dependencies): New variables. ("self-test …", "cargo-recursive-import-hoors-existing-packages"): New tests.
