methods: http: Drain pending data before selecting

2017-06-28T13:52:38Z

GnuTLS can already have data pending in its buffers, we need to to drain that first otherwise select() might block indefinitely. Gbp-Dch: ignore

methods: Add HTTPS support to http method, using GnuTLS

2017-06-28T13:52:38Z

The http method will eventually replace the curl-based https method, but for now, this is an opt-in experiment that can be enabled by setting Dir::Bin::Methods::https to "http". Known issues: - We do not support HTTPS proxies yet - We do not support proxying HTTPS connections yet (CONNECT) - IssuerCert and SslForceVersion are unsupported Gbp-Dch: Full

methods: connect: Switch from int fds to new MethodFd

2017-06-28T13:52:38Z

Use std::unique_ptr everywhere we used an integer-based file descriptor before. This allows us to implement stuff like TLS support easily. Gbp-Dch: ignore

rename ServerMethod to BaseHttpMethod

2016-12-31T01:29:21Z

This 'method' is the abstract base for http and https and should as such be called out like this rather using an easily confused name. Gbp-Dch: Ignore

separating state variables regarding server/request

2016-12-31T01:29:21Z

Having a Reset(bool) method to partially reset certain variables like the download size always were strange, so this commit splits the ServerState into an additional RequestState living on the stack for as long as we deal with this request causing an automatic "reset". There is much to do still to make this code look better, but this is a good first step which compiles cleanly and passes all tests, so keeping it as history might be beneficial and due to avoiding explicit memory allocations it ends up fixing a small memory leak in https, too. Closes: #440057

http: skip connection cleanup if we close it anyhow

2016-11-11T22:40:37Z

Suggested in #529794

improve SOCKS error messages for http slightly

2016-11-10T15:39:07Z

The 0.0.0.0:0 tor reports is pretty useless by itself, but even if an IP would be reported it is better to show the user the hostname we wanted the proxy to connect to in the same error message. We improve upon it further by looking for this bind address in particular and remap error messages slightly to give users a better chance of figuring out what went wrong. Upstream Tor can't do that as it is technically wrong.

don't sent Range requests if we know its not accepted

2016-08-16T16:49:37Z

If the server told us in a previous request that it isn't supporting Ranges with bytes via an Accept-Ranges header missing bytes, we don't try to formulate requests using Ranges.

reorganize server-states resetting in http/https

2016-08-16T16:49:37Z

We keep various information bits about the server around, some only effecting the currently handled file (like sizes) while others should be persistent (like pipeline detections). http used to reset all file-related manually, which is a bit silly if we already have a Reset() method – which does reset all through –, so extending it with a parameter for reuse and calling it from https too (as this was previously resetting by just creating a new state struct – it uses no value of the persistent state-keeping yet as it supports no pipelining). Gbp-Dch: Ignore

http: auto-configure for local Tor proxy if called as 'tor'

2016-08-10T23:34:39Z

With apts http transport supporting socks5h proxies and all the work in terms of configuration of methods based on the name it is called with it becomes surprisingly easy to implement Tor support equally (and perhaps even a bit exceeding) what is available currently in apt-transport-tor. How this will turn out to be handled packaging wise we will see in https://lists.debian.org/deity/2016/08/msg00012.html , but until this is resolved we can add the needed support without actively enabling it for now, so that this can be tested better.
