2014-08-26Pass ExpectedSize to tthe backend methodMichael Vogt
This ensures that we can stop downloading if the server send too much data by accident (or by a malicious attempt)
2014-05-09reenable pipelining via hashsum reordering supportDavid Kalnischkies
Now that methods have the expected hashes available they can check if the response from the server is what they expected. Pipelining is one of those areas in which servers can mess up by not supporting it properly, which forced us to disable it for the time being. Now, we check if we got a response out of order, which we can not only use to disable pipelining automatically for the next requests, but we can fix it up just like the server responded in proper order for the current requests. To ensure that this little trick works pipelining is only attempt if we have hashsums for all the files in the chain which in theory reduces the use of pipelining usage even on the many servers which work properly, but in practice only the InRelease file (or similar such) will be requested without a hashsum – and as it is the only file requested in that stage it can't be pipelined even if we wanted to. Some minor annoyances remain: The display of the progress we have doesn't reflect this change, so it looks like the same package gets downloaded multiple times while others aren't at all. Further more, partial files are not supported in this recovery as the received data was appended to the wrong file, so the hashsum doesn't match. Both seem to be minor enough to reenable pipelining by default until further notice through to test if it really solves the problem. This therefore reverts commit 8221431757c775ee875a061b184b5f6f2330f928.

2014-03-13cleanup headers and especially #includes everywhereDavid Kalnischkies
Beside being a bit cleaner it hopefully also resolves oddball problems I have with high levels of parallel jobs. Git-Dch: Ignore Reported-By: iwyu (include-what-you-use)

2013-10-01handle complete responses to https range requestsDavid Kalnischkies
Servers might respond with a complete file either because they don't support Ranges at all or the If-Range condition isn't statisfied, so we have to parse the headers curl gets ourself to seek or truncate the file we have so far. This also finially adds the testcase testing a bunch of partial situations for both, http and https - which is now all green. Closes: 617643, 667699 LP: 1157943
2013-10-01refactor http client implementationDavid Kalnischkies
No effective behavior change, just shuffling big junks of code between methods and classes to split them into those strongly related to our client implementation and those implementing HTTP. The idea is to get HTTPS to a point in which most of the implementation can be shared even though the client implementations itself is completely different. This isn't anywhere near yet though, but it should beenough to reuse at least a few lines from http in https now. Git-Dch: Ignore
