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.
2013-08-28configurable compression for testcasesDavid Kalnischkies
Compressing files in 4 different styles eats test-time for no practical gain if we don't test them explicitly, so default to just building 'gz' compressed files as it is the simplest compression algorithm supported Git-Dch: Ignore
2013-08-12add chronic-like testsuccess/testfailure helpersDavid Kalnischkies
For many commands the output isn't stable (like then dpkg is called) but the exitcode is, so this helper enhances the common && msgpass || msgfail by generating automatically a msgtest and showing the output of the command in case of failure instead of discarding it unconditionally, the later being chronic-like behaviour Git-Dch: Ignore
2013-06-24simple fork and pidfile aptwebserverDavid Kalnischkies
Forking only after being ready to accept clients avoids running races with the tests which sometimes failed on the first 'apt-get update' (or similar) with the previous background-start and hope for the best… The commit fixes also some oversight output-order changes in regards to Description-md5 and (I-M-S) race conditions in various tests. Git-Dch: Ignore

- operate optional on gzip compressed pdiffs * apt-pkg/acquire-item.cc: - don't uncompress downloaded pdiff files before feeding it to rred

2010-08-21* apt-pkg/acquire-item.cc:David Kalnischkies
- don't use ReadOnlyGzip mode for PDiffs as this mode doesn't work in combination with the AddFd methods of our hashclasses Add also 2 testcases: one to test pdiffs in general and one to test the handling of compressed indexes.
