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.

Record all available sources for descriptions

2025-01-30T23:10:02Z

Avoiding duplications is one thing, but it could also be handy to know all sources for a description so that you can e.g. avoid opening another file or similar such if its also present in one you already have open. Given how the structures were set up this was probably intended all along and either worked at some point or was abandoned for the duplicates that we started culling heavily with the introduction of MultiArch as at that point they blew up the cache and needed to be dealt with.

Drop unused version stanza size info from binary cache

2025-01-30T19:10:50Z

Same reason as with the description size before, but this one had actually one extremely dated user in src:apt left with dumpavail, which is changed to an implementation that is (in comparison) a bit slower, but should be good enough for a command that is ideally not used anymore (even if codesearch suggests otherwise). After all, what makes this a bit slower is not that we don't know the size, but that this one does additional work preparing for accessing the fields which we don't do. In exchange pkgTagFile has a better implementation for "Jitter" than the old code that we would "just" need to copy here if speed were really an issue.

Modernize standard library includes

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.

pkgnames: Do not exclude virtual packages with --all-names

2020-10-26T13:39:44Z

We accidentally excluded virtual packages by excluding every group that had a package, but where the package had no versions. Rewrite the code so the lookup consistently uses VersionList() instead of FirstVersion and FindPkg("any") - those are all the same, and this is easier to read.

pkgnames: Correctly set the default for AllNames to false

2020-10-26T13:33:55Z

We passed "false" instead of false, and that apparently got cast to bool, because it's a non-null pointer. LP: #1876495

Make map_pointer typesafe

2020-02-24T17:29:07Z

Instead of just using uint32_t, which would allow you to assign e.g. a map_pointer to a map_pointer, use our own smarter struct that has strict type checking. We allow creating a map_pointer from a nullptr, and we allow comparing map_pointer to nullptr, which also deals with comparisons against 0 which are often used, as 0 will be implictly converted to nullptr.

Replace map_pointer_t with map_pointer

2020-02-24T16:08:34Z

This is a first step to a type safe cache, adding typing information everywhere. Next, we'll replace map_pointer implementation with a type safe one.
