Remove some more unused functions

Final ABI cleanup before unstable?!

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}.

http: use Retry-After HTTP header to optimize retries

2024-11-18T12:44:49Z

Some mirrors like snapshot.debian.org apply strict http rate limits. While apt already has an exponential backoff mechanism implemented, this is not sufficient due to the following reasons: 1. all retries happen roughly at the same time 2. the retry-after information from the server is not used We fix this by improving the algorithm: First, if present, the timestamp or duration of the Retry-After header is added to the exponential backoff, optimizing for success-on-second-try. Second, a random delay is added (delay += [0, delay]) to distribute the retries to not immediately run into the limit again. To avoid super-long delays, this is capped by the configured maximum delay. This logic only becomes active if the option Acquire::Retries::HandleRetryAfter is enabled.

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.

Replace PrintStatus with SendMessage usage

2021-02-04T10:00:00Z

varg API is a nightmare as the symbols seems different on ever other arch, but more importantly SendMessage does a few checks on the content of the message and it is all outputted via C++ iostreams and not mixed in FILE* which is handy for overriding the streams.

Keep URIs encoded in the acquire system

2020-12-18T18:31:19Z

We do not deal a lot with URIs which need encoding, but then we do it is a pain that we store it decoded in the acquire system as it means we have to decode and reencode URIs eventually which is potentially giving us slightly different URIs. We see that in our own testing framework while setting up redirects as the config options are effectively double-encoded and decoded to pass them around successfully as otherwise %2f and / in an URI are treated the same. This commit adds the infrastructure for methods to opt into getting URIs send in encoded form (and returning them to us in encoded form, too) so that we eventually do not have to touch the URIs which is how it should be. This means though that we have to deal with methods who do not support this yet (aka: all at the moment) for which we decode and encode while communicating with them.

apt-pkg: default visibility to hidden

require methods to request AuxRequest capability at startup

2018-01-03T18:42:45Z

Allowing a method to request work from other methods is a powerful capability which could be misused or exploited, so to slightly limited the surface let method opt-in into this capability on startup.

refactor message generation for methods

2018-01-03T17:55:41Z

The format isn't too hard to get right, but it gets funny with multiline fields (which we don't really have yet) and its just easier to deal with it once and for all which can be reused for more messages later.
