	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). (%compression-methods): Move variable to (guix narinfo). * guix/narinfo.scm: New file. * Makefile.am (MODULES): Add it. * po/guix/POTFILES.in: Add 'guix/narinfo.scm'.
2020-12-19	tests: Check the mtime and permissions of substituted items.	Ludovic Courtès
	* tests/store.scm ("substitute") ("substitute + build-things with output path") ("substitute + build-things with specific output"): Call 'canonical-file?'. * tests/substitute.scm ("substitute, authorized key"): Check the mtime and permissions of "substitute-retrieved".
2020-12-19	daemon: 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. (SubstitutionGoal::handleChildOutput): Remove 'expectedHashStr' handling. * tests/substitute.scm ("substitute, invalid hash"): Rename to... ("substitute, invalid narinfo hash"): ... this. ("substitute, invalid hash"): New test.
2020-12-08	daemon: 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. Loop reading line from stdin. * tests/substitute.scm <top level>: Call '%error-to-file-descriptor-4?'. (request-substitution): New procedure. ("substitute, no signature") ("substitute, invalid hash") ("substitute, unauthorized key") ("substitute, authorized key") ("substitute, unauthorized narinfo comes first") ("substitute, unsigned narinfo comes first") ("substitute, first narinfo is unsigned and has wrong hash") ("substitute, first narinfo is unsigned and has wrong refs") ("substitute, two invalid narinfos") ("substitute, narinfo with several URLs"): Adjust to new "guix substitute --substitute" calling convention.
2020-12-08	daemon: Use 'Agent' to spawn 'guix substitute --query'.	Ludovic Courtès
	* nix/libstore/local-store.hh (RunningSubstituter): Remove. (LocalStore)[runningSubstituter]: Change to unique_ptr<Agent>. [setSubstituterEnv, didSetSubstituterEnv]: Remove. [getLineFromSubstituter, getIntLineFromSubstituter]: Take an 'Agent'. * nix/libstore/local-store.cc (LocalStore::~LocalStore): Remove reference to 'runningSubstituter'. (LocalStore::setSubstituterEnv, LocalStore::startSubstituter): Remove. (LocalStore::getLineFromSubstituter): Adjust to 'run' being an 'Agent'. (LocalStore::querySubstitutablePaths): Spawn substituter agent if needed. Adjust to 'Agent' interface. (LocalStore::querySubstitutablePathInfos): Likewise. * nix/libstore/build.cc (SubstitutionGoal::tryToRun): Remove call to 'setSubstituterEnv' and add 'setenv' call for "_NIX_OPTIONS" instead. (SubstitutionGoal::finished): Remove 'readLine' call for 'dummy'. * guix/scripts/substitute.scm (%allow-unauthenticated-substitutes?): Remove second argument to 'make-parameter'. (process-query): Call 'warn-about-missing-authentication' when (%allow-unauthenticated-substitutes?) is #t. (guix-substitute): Wrap body in 'parameterize'. Set 'guix-warning-port' too. No longer exit when 'substitute-urls' returns the empty list. No longer print newline initially. * tests/substitute.scm (test-quit): Parameterize 'current-error-port' to account for the port changes in 'guix-substitute'.
