2014-01-21methods/rred: minor robustness improvementsAnthony Towns
Use retry_fwrite to better handle partial fwrite successes, and to keep the Hashes in sync with what's actually written.
2014-01-16correct some style/performance/warnings from cppcheckDavid Kalnischkies
The most "visible" change is from utime to utimensat/futimens as the first one isn't part of POSIX anymore. Reported-By: cppcheck Git-Dch: Ignore
2014-01-15integrate Anthonys rred with POC for client-side mergeDavid Kalnischkies
Providing the benefits of both without the downsides :) (ABI breaks or external dependencies) For this Anthonys rred is equipped with: - magic-filename-pickup of patches rather than explicit messages - use of FileFd instead of FILE* to get on-the-fly uncompress of the gzip compressed pdiff patches The acquire code in turn stops checking for apt-file's helper as our own rred is now clever enough for our needs.
2014-01-15reimplement rred to allow applying all the diffs in a single passAnthony Towns
Based on the idea presented in: https://lists.debian.org/deity/2009/08/msg00169.html and https://lists.debian.org/debian-devel/2014/01/msg00081.html It reads all patches one by one and merges them in-memory before applying the merged changes to the index. Beware: This commit by David Kalnischkies rips out the rred binary rewrite unchanged (expect minor format issue corrections) from the proposed changes, so this commit alone BREAKS pdiff completely. The integration into the acquire system as it was prepared in the previous POC will be done in the next commit to have proper 'blame'.
2013-12-13implement POC client-side merging of pdiffs via apt-fileDavid Kalnischkies
The idea of pdiffs is to avoid downloading the hole file by patching the existing index. This works very well, but becomes slow if a lot of patches needs to be applied to reconstruct an up-to-date index and in recent years more and more dinstall (or similar) runs are executed creating more and more pdiffs in the same amount of time, so pdiffs became less useful. The solution is simple: Reduce the amount of patches (which are very small) which need to be applied on top of the index we have available (which is usually pretty big). This can be done in two ways: Either merge the patches on the server-side so that the client has to download only one patch or the patches are all downloaded and merged on the client-side. The first needs a client who is doing one step at a time who can also skip patches if it needs (APT supports this for a long time now). The later is implemented by this commit, but depends on the server NOT merging the patches and the patches being in a strict order in which no patch is skipped. This is traditionally the case for dak, but other repository creators support merging – e.g. reprepro (which helpfully adds a flag indicating that the patches are merged). To support both or even mixes a client needs more information which isn't available for now. This POC uses the external diffindex-rred included in apt-file to do the heavy lifting of merging & applying all patches in one pass, hence to test this feature apt-file needs to be installed.
2013-10-22add Acquire::http::Proxy-Auto-Detect to the apt.conf.5 manpage (closes: 726597)Michael Vogt
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
2013-10-01fix partial (206 and 416) support in httpsDavid Kalnischkies
As lengthy discussed in lp:1157943 partial https support was utterly broken as a 206 response was handled as an (unhandled) error. This is the first part of fixing it by supporting a 206 response and starting to deal with 416.
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
2013-10-01replace "filesize - 1" trick in http with proper 416 handlingDavid Kalnischkies
Our http client requests the "filesize - 1" for the small edgecase of handling a file which was completely downloaded, but not yet moved to the correct place as we get 416 errors in that case, but as we can handle 416 returns now we just special-case the situation of requesting the exact filesize and handle it as a 200 without content instead.
2013-10-01retry without partial data after a 416 responseDavid Kalnischkies
If we get a 416 from the server it means the Range we asked for is above the real filesize of the file on the server. Mostly this happens if the server isn't supporting If-Range, but regardless of how we end up with the partial data, the data is invalid so we discard it and retry with a fresh plate and hope for the best. Old behavior was to consider 416 an error and retry with a different compression until we ran out of compression and requested the uncompressed file (which doesn't exist on most mirrors) with an accept line which server answered with "406 Not Acceptable".

2013-06-20trigger NODATA error for invalid InRelease filesDavid Kalnischkies
With the selfgrown splitting we got the problem of not recovering from networks which just reply with invalid data like those sending us login pages to authenticate with the network (e.g. hotels) back. The good thing about the InRelease file is that we know that it must be clearsigned (a Release file might or might not have a detached sig) so if we get a file but are unable to split it something is seriously wrong, so there is not much point in trying further. The Acquire system already looks out for a NODATA error from gpgv, so this adds a new error message sent to the acquire system in case the splitting we do now ourselves failed including this magic word. Closes: #712486
