2017-07-26reimplement and document auth.confDavid Kalnischkies
We have support for an netrc-like auth.conf file since 0.7.25 (closing 518473), but it was never documented in apt that it even exists and netrc seems to have fallen out of usage as a manpage for it no longer exists making the feature even more arcane. On top of that the code was a bit of a mess (as it is written in c-style) and as a result the matching of machine tokens to URIs also a bit strange by checking for less specific matches (= without path) first. We now do a single pass over the stanzas. In practice early adopters of the undocumented implementation will not really notice the differences and the 'new' behaviour is simpler to document and more usual for an apt user. Closes: #811181
2017-07-26fail early in http if server answer is too small as wellDavid Kalnischkies
Failing on too much data is good, but we can do better by checking for exact filesizes as we know with hashsums how large a file should be, so if we get a file which has a size we do not expect we can drop it directly, regardless of if the file is larger or smaller than what we expect which should catch most cases which would end up as hashsum errors later now a lot sooner.
2017-07-26don't try to parse all fields starting with HTTP as status-lineDavid Kalnischkies
It is highly unlikely to encounter fields which start with HTTP in practice, but we should really be a bit more restrictive here.
2017-07-12Reformat and sort all includes with clang-formatJulian Andres Klode
This makes it easier to see which headers includes what. The changes were done by running git grep -l '#\s*include' \ | grep -E '.(cc|h)$' \ | xargs sed -i -E 's/(^\s*)#(\s*)include/\1#\2 include/' To modify all include lines by adding a space, and then running ./git-clang-format.sh.
2017-07-01http: A response with Content-Length: 0 has no contentJulian Andres Klode
APT considered any response with a Content-Length to have a body, even if the value of the header was 0. A 0 length body however, is equal to no body.
2017-06-26deal with 3xx httpcodes as required by HTTP/1.1 specDavid Kalnischkies
An unknown code should be handled the same as the x00 code of this group, but for redirections we used to treat 300 (and a few others) as an error while unknown codes were considered redirections. Instead we check now explicitly for the redirection codes we support for redirecting (and add the 308 defined in RFC 7538) to avoid future problems if new 3xx codes are added expecting certain behaviours. Potentially strange would have been e.g. "305 Use Proxy" sending a Location for the proxy to use – which wouldn't have worked and resulted in an error anyhow, but probably confused users in the process.
2017-01-24basehttp: Only read Content-Range on 416 and 206 responsesJulian Andres Klode
This fixes issues with sourceforge where the redirector includes such a Content-Range in a 302 redirect. Since we do not really know what file is meant in a redirect, let's just ignore it for all responses other than 416 and 206. Maybe we should also get rid of the other errors, and just ignore the field in those cases as well? LP: #1657567
2017-01-19fix various typos reported by spellintianDavid Kalnischkies
Most of them in (old) code comments. The two instances of user visible string changes the po files of the manpages are fixed up as well. Gbp-Dch: Ignore Reported-By: spellintian
2016-12-31rename ServerMethod to BaseHttpMethodDavid Kalnischkies
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
