edsp: Write 'Size' to the EDSP files

2025-03-03T10:21:55Z

This allows solvers to optimize by download size; and gives us a better means of interpreting "downloadable" debs (they must have a size > 0 after all).

Consider 0-size debs not downloadable, set a size in EDSP

2025-03-03T10:21:55Z

EDSP dumps all appear as a single file, so we cannot determine correctly if a package is obsolete. We can fix this by ensuring that only debs with a size are downloadable, and then by faking a size in EDSP: The size is 1 if APT-Release is set (there is a source to download it from) or 0 otherwise. This ensures that the obsolete logic in solver3 works correctly, as well as the obsolete patterns, if anyone could actually use it on the EDSP files.

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.

edsp: Parse source version from the Source-Version field

2024-05-30T07:53:08Z

EDSP uses the Source-Version field instead of storing the source version in the Source field with the package name, adjust our parser accordingly. Use the override in the edspLikeListParser to do so rather than dumb this into the correct place in the debListParser.

Use pkgTagSection::Key in more places in src:apt

2022-04-01T12:16:19Z

The speed critical paths were converted earlier, but the remaining could benefit a tiny bit from this as well especially as we have the facility now available and can therefore brush up the code in various places in the process as well. Also takes the time to add the hidden Exists method advertised in the headers, but previously not implemented.

Stop parsing undocumented unknown EDSP field APT-Hash

2022-04-01T12:16:19Z

It was introduced in the first commit for EDSP, but beside this reference, never appears in documentation and code. Seems like an earlier name of what APT-ID ended up to be and as such should be more than safely being able to retire now.

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.

Use a 32-bit djb VersionHash instead of CRC-16

Remove includes of (md5|sha1|sha2).h headers

2020-01-14T12:10:36Z

Remove it everywhere, except where it is still needed.
