From 49cd7387ad6546571ca31a41f208091b482defaa Mon Sep 17 00:00:00 2001 From: Eelco Dolstra Date: Thu, 28 Jun 2012 17:19:32 -0400 Subject: [PATCH 01/78] nix-push: create a manifest-less binary cache Manifests are a huge pain, since users need to run nix-pull directly or indirectly to obtain them. They tend to be large and lag behind the available binaries; also, the downloaded manifests in /nix/var/nix/manifest need to be in sync with the Nixpkgs sources. So we want to get rid of them. The idea of manifest-free operation works as follows. Nix is configured with a set of URIs of binary caches, e.g. http://nixos.org/binary-cache Whenever Nix needs a store path X, it checks each binary cache for the existence of a file /.narinfo, e.g. http://nixos.org/binary-cache/bi1gh9...ia17.narinfo The .narinfo file contains the necessary information about the store path that was formerly kept in the manifest, i.e., (relative) URI of the compressed NAR, references, size, hash, etc. For example: StorePath: /nix/store/xqp4l88cr9bxv01jinkz861mnc9p7qfi-neon-0.29.6 URL: 1bjxbg52l32wj8ww47sw9f4qz0r8n5vs71l93lcbgk2506v3cpfd.nar.bz2 CompressedHash: sha256:1bjxbg52l32wj8ww47sw9f4qz0r8n5vs71l93lcbgk2506v3cpfd CompressedSize: 202542 NarHash: sha256:1af26536781e6134ab84201b33408759fc59b36cc5530f57c0663f67b588e15f NarSize: 700440 References: 043zrsanirjh8nbc5vqpjn93hhrf107f-bash-4.2-p24 cj7a81wsm1ijwwpkks3725661h3263p5-glibc-2.13 ... Deriver: 4idz1bgi58h3pazxr3akrw4fsr6zrf3r-neon-0.29.6.drv System: x86_64-linux Nix then knows that it needs to download http://nixos.org/binary-cache/1bjxbg52l32wj8ww47sw9f4qz0r8n5vs71l93lcbgk2506v3cpfd.nar.bz2 to substitute the store path. Note that the store directory is omitted from the References and Deriver fields to save space, and that the URL can be relative to the binary cache prefix. This patch just makes nix-push create binary caches in this format. The next step is to make a substituter that supports them. --- scripts/nix-push.in | 254 ++++++++++++++++---------------------------- 1 file changed, 94 insertions(+), 160 deletions(-) diff --git a/scripts/nix-push.in b/scripts/nix-push.in index a1c02190b..db94b51fd 100755 --- a/scripts/nix-push.in +++ b/scripts/nix-push.in @@ -1,10 +1,13 @@ #! @perl@ -w @perlFlags@ use strict; +use File::Basename; use File::Temp qw(tempdir); +use File::Path qw(mkpath); use File::stat; +use File::Copy; use Nix::Config; -use Nix::Manifest; +use Nix::Store; my $hashAlgo = "sha256"; @@ -12,7 +15,6 @@ my $tmpDir = tempdir("nix-push.XXXXXX", CLEANUP => 1, TMPDIR => 1) or die "cannot create a temporary directory"; my $nixExpr = "$tmpDir/create-nars.nix"; -my $manifest = "$tmpDir/MANIFEST"; my $curl = "$Nix::Config::curl --fail --silent"; my $extraCurlFlags = ${ENV{'CURL_FLAGS'}}; @@ -22,18 +24,14 @@ $curl = "$curl $extraCurlFlags" if defined $extraCurlFlags; # Parse the command line. my $localCopy; my $localArchivesDir; -my $localManifestFile; - -my $targetArchivesUrl; my $archivesPutURL; my $archivesGetURL; -my $manifestPutURL; sub showSyntax { print STDERR <$nixExpr"; print NIX "["; @@ -112,172 +101,117 @@ print NIX "]"; close NIX; -# Instantiate store derivations from the Nix expression. -my @storeExprs; -print STDERR "instantiating store derivations...\n"; -my $pid = open(READ, "$Nix::Config::binDir/nix-instantiate $nixExpr|") - or die "cannot run nix-instantiate"; +# Build the Nix expression. +print STDERR "building compressed archives...\n"; +my @narPaths; +my $pid = open(READ, "$Nix::Config::binDir/nix-build $nixExpr|") + or die "cannot run nix-build"; while () { chomp; die unless /^\//; - push @storeExprs, $_; + push @narPaths, $_; } -close READ or die "nix-instantiate failed: $?"; +close READ or die "nix-build failed: $?"; -# Build the derivations. -print STDERR "creating archives...\n"; +# Upload the archives and the corresponding info files. +print STDERR "uploading/copying archives...\n"; -my @narPaths; +my $totalNarSize = 0; +my $totalNarBz2Size = 0; -my @tmp = @storeExprs; -while (scalar @tmp > 0) { - my $n = scalar @tmp; - if ($n > 256) { $n = 256 }; - my @tmp2 = @tmp[0..$n - 1]; - @tmp = @tmp[$n..scalar @tmp - 1]; - - my $pid = open(READ, "$Nix::Config::binDir/nix-store --realise @tmp2|") - or die "cannot run nix-store"; - while () { - chomp; - die unless (/^\//); - push @narPaths, "$_"; - } - close READ or die "nix-store failed: $?"; -} - - -# Create the manifest. -print STDERR "creating manifest...\n"; - -my %narFiles; -my %patches; - -my @narArchives; for (my $n = 0; $n < scalar @storePaths; $n++) { my $storePath = $storePaths[$n]; my $narDir = $narPaths[$n]; - - $storePath =~ /\/([^\/]*)$/; - my $basename = $1; - defined $basename or die; + my $baseName = basename $storePath; - open HASH, "$narDir/narbz2-hash" or die "cannot open narbz2-hash"; - my $narbz2Hash = ; - chomp $narbz2Hash; - $narbz2Hash =~ /^[0-9a-z]+$/ or die "invalid hash"; - close HASH; - - my $narName = "$narbz2Hash.nar.bz2"; - - my $narFile = "$narDir/$narName"; - (-f $narFile) or die "narfile for $storePath not found"; - push @narArchives, $narFile; - - my $narbz2Size = stat($narFile)->size; - - my $references = `$Nix::Config::binDir/nix-store --query --references '$storePath'`; - die "cannot query references for `$storePath'" if $? != 0; - $references = join(" ", split(" ", $references)); - - my $deriver = `$Nix::Config::binDir/nix-store --query --deriver '$storePath'`; - die "cannot query deriver for `$storePath'" if $? != 0; - chomp $deriver; - $deriver = "" if $deriver eq "unknown-deriver"; - - my $narHash = `$Nix::Config::binDir/nix-store --query --hash '$storePath'`; - die "cannot query hash for `$storePath'" if $? != 0; - chomp $narHash; + # Get info about the store path. + my ($deriver, $narHash, $time, $narSize, $refs) = queryPathInfo($storePath); # In some exceptional cases (such as VM tests that use the Nix # store of the host), the database doesn't contain the hash.

A package or NixOS system configuration can have hundreds of dependencies, and in the worst case (when the local info cache is empty) we have to do a separate HTTP request for each of these. If the ping time to the server is t, getting N info files will take tN seconds; e.g., with a ping time of 0.1s to nixos.org, sequentially downloading 1000 info files (a typical NixOS config) will take at least 100 seconds. To fix this problem, the binary cache substituter can now perform requests in parallel. This required changing the substituter interface to support a function querySubstitutablePathInfos() that queries multiple paths at the same time, and rewriting queryMissing() to take advantage of parallelism. (Due to local caching, parallelising queryMissing() is sufficient for most use cases, since it's almost always called before building a derivation and thus fills the local info cache.) For example, parallelism speeds up querying all 1056 paths in a particular NixOS system configuration from 116s to 2.6s. It works so well because the eccentricity of the top-level derivation in the dependency graph is only 9. So we only need 10 round-trips (when using an unlimited number of parallel connections) to get everything. Currently we do a maximum of 150 parallel connections to the server. Thus it's important that the binary cache server (e.g. nixos.org) has a high connection limit. Alternatively we could use HTTP pipelining, but WWW::Curl doesn't support it and libcurl has a hard-coded limit of 5 requests per pipeline. --- scripts/download-from-binary-cache.pl.in | 206 ++++++++++++++--------- src/libstore/build.cc | 10 +- src/libstore/globals.cc | 5 +- src/libstore/local-store.cc | 60 ++++--- src/libstore/local-store.hh | 7 +- src/libstore/misc.cc | 110 ++++++++---- src/libstore/remote-store.cc | 13 ++ src/libstore/remote-store.hh | 3 + src/libstore/store-api.hh | 5 + 9 files changed, 285 insertions(+), 134 deletions(-) diff --git a/scripts/download-from-binary-cache.pl.in b/scripts/download-from-binary-cache.pl.in index ea37c818d..a67818e7f 100644 --- a/scripts/download-from-binary-cache.pl.in +++ b/scripts/download-from-binary-cache.pl.in @@ -12,33 +12,40 @@ use strict; my @binaryCacheUrls = map { s/\/+$//; $_ } split(/ /, ($ENV{"NIX_BINARY_CACHES"} || "")); +my $maxParallelRequests = 150; + my ($dbh, $insertNAR, $queryNAR, $insertNegativeNAR, $queryNegativeNAR); my %cacheIds; my $curlm = WWW::Curl::Multi->new; my $activeRequests = 0; my $curlIdCount = 1; -my %curlHandles; +my %requests; +my %scheduled; my $caBundle = $ENV{"CURL_CA_BUNDLE"} || $ENV{"OPENSSL_X509_CERT_FILE"}; sub addRequest { - my ($url) = @_; + my ($storePath, $url) = @_; my $curl = WWW::Curl::Easy->new; my $curlId = $curlIdCount++; - $curlHandles{$curlId} = { handle => $curl, content => "" }; + $requests{$curlId} = { storePath => $storePath, url => $url, handle => $curl, content => "" }; $curl->setopt(CURLOPT_PRIVATE, $curlId); $curl->setopt(CURLOPT_URL, $url); - $curl->setopt(CURLOPT_WRITEDATA, \$curlHandles{$curlId}->{content}); + $curl->setopt(CURLOPT_WRITEDATA, \$requests{$curlId}->{content}); $curl->setopt(CURLOPT_FOLLOWLOCATION, 1); $curl->setopt(CURLOPT_CAINFO, $caBundle) if defined $caBundle; - $curlm->add_handle($curl); - $activeRequests++; + if ($activeRequests >= $maxParallelRequests) { + $scheduled{$curlId} = 1; + } else { + $curlm->add_handle($curl); + $activeRequests++; + } - return $curlHandles{$curlId}; + return $requests{$curlId}; } @@ -55,12 +62,20 @@ sub processRequests { if ($curlm->perform() != $activeRequests) { while (my ($id, $result) = $curlm->info_read) { if ($id) { - my $handle = $curlHandles{$id}->{handle}; - $curlHandles{$id}->{result} = $result; - $curlHandles{$id}->{httpStatus} = $handle->getinfo(CURLINFO_HTTP_CODE); - #print STDERR "\nRequest completed ($id, $result, $curlHandles{$id}->{httpStatus})\n"; + my $handle = $requests{$id}->{handle}; + $requests{$id}->{result} = $result; + $requests{$id}->{httpStatus} = $handle->getinfo(CURLINFO_HTTP_CODE); + #print STDERR "\nRequest completed ($id, $result, $requests{$id}->{httpStatus})\n"; $activeRequests--; - delete $curlHandles{$id}->{handle}; + delete $requests{$id}->{handle}; + + if (scalar(keys %scheduled) > 0) { + my $id2 = (keys %scheduled)[0]; + $curlm->add_handle($requests{$id2}->{handle}); + $activeRequests++; + delete $scheduled{$id2}; + } + } } } @@ -130,23 +145,21 @@ EOF } -sub getInfoFrom { - my ($storePath, $pathHash, $binaryCacheUrl) = @_; +sub negativeHit { + my ($storePath, $binaryCacheUrl) = @_; + $queryNegativeNAR->execute(getCacheId($binaryCacheUrl), basename($storePath)); + return @{$queryNegativeNAR->fetchall_arrayref()} != 0; +} - my $cacheId = getCacheId($binaryCacheUrl); - # Bail out if there is a negative cache entry. - $queryNegativeNAR->execute($cacheId, basename($storePath)); - return undef if @{$queryNegativeNAR->fetchall_arrayref()} != 0; +sub processNARInfo { + my ($storePath, $binaryCacheUrl, $request) = @_; - my $infoUrl = "$binaryCacheUrl/$pathHash.narinfo"; - print STDERR "checking $infoUrl...\n"; - my $request = addRequest($infoUrl); - processRequests; + my $cacheId = getCacheId($binaryCacheUrl); if ($request->{result} != 0 || $request->{httpStatus} != 200) { if ($request->{httpStatus} != 404) { - print STDERR "could not download ‘$infoUrl’ (" . + print STDERR "could not download ‘$request->{url}’ (" .
