2014-10-23chown finished partial files earlierDavid Kalnischkies
partial files are chowned by the Item baseclass to let the methods work with them. Now, this baseclass is also responsible for chowning the files back to root instead of having various deeper levels do this. The consequence is that all overloaded Failed() methods now call the Item::Failed base as their first step. The same is done for Done(). The effect is that even in partial files usually don't belong to _apt anymore, helping sneakernets and reducing possibilities of a bad method modifying files not belonging to them. The change is supported by the framework not only supporting being run as root, but with proper permission management, too, so that privilege dropping can be tested with them.
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.
2014-05-09use 'best' hash for source authenticationDavid Kalnischkies
Collect all hashes we can get from the source record and put them into a HashStringList so that 'apt-get source' can use it instead of using always the MD5sum. We therefore also deprecate the MD5 struct member in favor of the list. While at it, the parsing of the Files is enhanced so that records which miss "Files" (aka MD5 checksums) are still searched for other checksums as they include just as much data, just not with a nice and catchy name.
