Package: apt Version: 1.5~beta1 Severity: normal Tags: patch Dear APT Maintainers, 1.5 introduced a check that warns users about components specified in sources.list but not present in the Release file's Component section. While doing so, it assumes that any component that includes a slash should be treated like the components in security.debian.org, which are specified without a slash in sources.list (as "updates" is part of the suite), but with a slash in Release ("updates/main updates/contrib" etc). This leads to spurious warnings on repositories that use slashes in components in a more "regular" way. Take for example the following sources.list entry: deb http://deb.example.com/debian stretch profile/es And the following Release file Codename: stretch Components: main profile/es apt will mangle the supported component list to ['main', 'es'], thus complaining with the following warning: W: Skipping acquire of configured file 'profile/es/i18n/Translation-en_US' as repository 'http://debian.example.com/debian stretch InRelease' doesn't have the component 'profile/es' (component misspelt in sources.list?) The attached patch fixes this issue. Regards, Apollon
From fda828a6aca867be7e48997c90ca67386c646365 Mon Sep 17 00:00:00 2001 From: Apollon Oikonomopoulos <apoikos@debian.org> Date: Wed, 12 Jul 2017 10:41:58 +0300 Subject: [PATCH] Handle supported components with slashes in sources.list Commit d7c92411dc1f4c6be098d1425f9c1c075e0c2154 parses the Components section of (In)Release and attempts to detect the distribution's supported components. While doing so, it handles component names with slashes in a special manner, assuming that the actual component is only the part after the final slash. This is done to handle security.debian.org, which usually appears in sources.list as follows: deb http://s.d.o/debian-security stretch/updates main contrib non-free while the actual release file has: Codename: stretch Components: updates/main updates/contrib updates/non-free While this special handing on APTs part indeed works for debian-security, it emits spurious warnings on repositories that actually use slashes in the component names *and* appear so in sources.list. We fix this by adding both component versions (whole and final part) to the SupportedComponents array. --- apt-pkg/deb/debmetaindex.cc | 5 ++--- test/integration/test-apt-update-disappeared-component | 14 ++++++++++---- 2 files changed, 12 insertions(+), 7 deletions(-) diff --git a/apt-pkg/deb/debmetaindex.cc b/apt-pkg/deb/debmetaindex.cc index df7419ddd..d7c458e66 100644 --- a/apt-pkg/deb/debmetaindex.cc +++ b/apt-pkg/deb/debmetaindex.cc @@ -414,10 +414,9 @@ bool debReleaseIndex::Load(std::string const &Filename, std::string * const Erro if (comp.empty()) continue; auto const pos = comp.find_last_of('/'); - if (pos == std::string::npos) - d->SupportedComponents.push_back(std::move(comp)); - else // e.g. security.debian.org uses this style + if (pos != std::string::npos) // e.g. security.debian.org uses this style d->SupportedComponents.push_back(comp.substr(pos + 1)); + d->SupportedComponents.push_back(std::move(comp)); } { decltype(pkgCache::ReleaseFile::Flags) flags = 0; diff --git a/test/integration/test-apt-update-disappeared-component b/test/integration/test-apt-update-disappeared-component index d38405bc2..7c7dd7711 100755 --- a/test/integration/test-apt-update-disappeared-component +++ b/test/integration/test-apt-update-disappeared-component @@ -10,13 +10,14 @@ insertpackage 'unstable' 'foobar' 'all' '1' APTARCHIVE="file:$(readlink -f ./aptarchive) unstable InRelease" setupaptarchive --no-update -sed -i -e 's#main\s*$#main contrib non-free#' rootdir/etc/apt/sources.list.d/* +sed -i -e 's#main\s*$#main contrib non-free sub/component#' rootdir/etc/apt/sources.list.d/* # if no Component info is available we assume all are supported, which means # that non-existent Packages files are assumed to be missing because they are # empty (as the repository is declaring support for them via Architectures) testwarningmsg "W: Skipping acquire of configured file 'contrib/source/Sources' as repository '${APTARCHIVE}' does not seem to provide it (sources.list entry misspelt?) -W: Skipping acquire of configured file 'non-free/source/Sources' as repository '${APTARCHIVE}' does not seem to provide it (sources.list entry misspelt?)" apt update +W: Skipping acquire of configured file 'non-free/source/Sources' as repository '${APTARCHIVE}' does not seem to provide it (sources.list entry misspelt?) +W: Skipping acquire of configured file 'sub/component/source/Sources' as repository '${APTARCHIVE}' does not seem to provide it (sources.list entry misspelt?)" apt update sed -i -e '/^Codename: / a\ Components: main contrib' $(find ./aptarchive -name 'Release') @@ -24,16 +25,21 @@ signreleasefiles testwarningmsg "W: Skipping acquire of configured file 'contrib/source/Sources' as repository '${APTARCHIVE}' does not seem to provide it (sources.list entry misspelt?)
