pkgcache: Change inline to constexpr noexcept

2026-02-10T19:59:03Z

In particular, map_pointer and iterators are now all literal types, with most functions translated to constexpr noexcept. This allows them to be used in constexpr contexts in C++17; and the compiler to generate better code knowing they cannot throw exceptions. This transformation is safe, because the functions are inline. more constexpr

Implement architecture variants

2025-10-25T18:42:14Z

Architecture variants are children of an architecture that share the same ABI but are optimized for different ISA levels. They are available in Ubuntu 25.10 and newer, and not supported in Debian or other distributions. A deb built for a variant contains the Architecture-Variant field, and the Architecture field points to the baseline, for example: Architecture: amd64 Architecture-Variant: amd64v3 However, the apt-get indextargets command reports the variant in the Architecture: field, and most of the code in APT presents the variant as the architecture. There are two types of variants: 1. Standalone variants are recorded in the Architectures field of the Release file as if they were a real architecture: Architectures: amd64 amd64v3 Standalone architecture variants only fetch the standalone architecture variant's Packages file. To do this, this patch changes the code such that the variants indextargets "supplant" the base targets. This may have complicated outcomes on the apt-get indextargets command. 2. Other variants can only be identified by their files being recorded with hashes in the Release file. APT fetches both the base architecture's as well as the variant's Packages file. Variants are configured in the APT::Architecture-Variants list. Image builders may want to build specific variant images using APT::Architecture-Variants { "amd64v3"; } But this commit also implements an automatic discovery mechanism using the varianttable and /proc/cpuinfo.

Fix indentation compiler warning with clang

2025-08-26T11:51:04Z

This commit fixes the following compiler warning. cacheiterators.h:423:54: warning: misleading indentation; statement is not part of the previous 'if' [-Wmisleading-indentation]

cache: Introduce partial SourceVersion support

2025-02-15T15:37:19Z

This is the first step that introduces a 1:1 mapping between version and source version. In a future version this can use the fields currently marked unavailable to deduplicate the SourceVersion objects across the group. The policy gains a member for storing pins for sourceversions. Together, in the future we should be able to determine candidates for source versions.

APT::StringView -> std::string_view [textonly]

Add DepIterator::IsSatisfied(PkgIterator)

2025-02-14T18:04:56Z

This allows checking if a dependency is satisfied by all versions of a package.

Drop APT_DEPRECATED usage

2025-01-05T22:16:08Z

C++14 includes the standard attribute, so we can use that instead. Note that we drop the deprecation of {Pkg,Dep}Iterator::operator<< as this is ignored (a friends declaration must be a definition to have attributes) very noisily by GCC >= 12 and the methods can be somewhat useful in debugging if you are to lazy to get APT::Pretty{Pkg,Dep}.

Modernize standard library includes

2024-02-20T12:49:04Z

This was automated with sed and git-clang-format, and then I had to fix up the top of policy.cc by hand as git-clang-format accidentally indented it by two spaces.

Add public phased update API

2024-02-13T13:27:27Z

This moves the functions of the PhasedUpgrader class into various other classes so they can be publicly exposed. This introduces three new functions: pkgDepCache::PhasingApplied() tells you whether phasing should be applied to the package. pkgProblemResolver::KeepPhasedUpdates() keeps back updates that have phasing applied. pkgCache::VerIterator::IsSecurityUpdate() determines whether this version contains security fixes.
