http: Fix handling of server connection closure

2018-11-12T10:51:56Z

If the server closed the connection while we're reading data, and we end up not having any data left to write; that is, for example, we received 0 bytes, then we did not exit before, as we only returned success if there was data to write. This is wrong: Obviously, if we have reached our limit, we are done anyway. It's a bit unclear if we actually ever reached this part, but it does make some sense wrt the bug below. LP: #1801338

Use steady clock source for bandwidth limitation

Using the time of day for this is slightly wrong just like it is for progress, just less visible.

Remove unused time-tracking from http method

2018-05-28T15:59:38Z

The Stats method isn't called anywhere, was partly commented out before, but we keep updating the time for it – lets avoid this pointless busywork. Gbp-Dch: Ignore

Lower default timeout from 120s to 30s

2018-05-24T12:31:31Z

120s is an insanely high default time out, lower it to 30s to make things a bit nicer.

reimplement and simplify mirror:// method

2018-01-03T17:55:41Z

Embedding an entire acquire stack and HTTP logic in the mirror method made it rather heavy weight and fragile. This reimplement goes the other way by doing only the bare minimum in the method itself and instead redirect the actual download of files to their proper methods. The reimplementation drops the (in the real world) unused query-string feature as it isn't really implementable in the new architecture.

report transient errors as transient errors

2017-12-13T22:56:29Z

The Fail method for acquire methods has a boolean parameter indicating the transient-nature of a reported error. The problem with this is that Fail is called very late at a point where it is no longer easily identifiable if an error is indeed transient or not, so some calls were and some weren't and the acquire system would later mostly ignore the transient flag and guess by using the FailReason instead. Introducing a tri-state enum we can pass the information about fatal or transient errors through the callstack to generate the correct fails.

Also look at https_proxy for https URLs

We accidentally regressed here in 1.5 when replacing the https method.

Sandbox methods with seccomp-BPF; except cdrom, gpgv, rsh

2017-10-22T21:38:31Z

This reduces the number of syscalls to about 140 from about 350 or so, significantly reducing security risks. Also change prepare-release to ignore the architecture lists in the build dependencies when generating the build-depends package for travis. We might want to clean up things a bit more and/or move it somewhere else.
