2015-06-12store Release files data in the CacheDavid Kalnischkies
We used to read the Release file for each Packages file and store the data in the PackageFile struct even through potentially many Packages (and Translation-*) files could use the same data. The point of the exercise isn't the duplicated data through. Having the Release files as first-class citizens in the Cache allows us to properly track their state as well as allows us to use the information also for files which aren't in the cache, but where we know to which Release file they belong (Sources are an example for this). This modifies the pkgCache structs, especially the PackagesFile struct which depending on how libapt users access the data in these structs can mean huge breakage or no visible change. As a single data point: aptitude seems to be fine with this. Even if there is breakage it is trivial to fix in a backportable way while avoiding breakage for everyone would be a huge pain for us. Note that not all PackageFile structs have a corresponding ReleaseFile. In particular the dpkg/status file as well as *.deb files have not. As these have only a Archive property need, the Component property takes over this duty and the ReleaseFile remains zero. This is also the reason why it isn't needed nor particularily recommended to change from PackagesFile to ReleaseFile blindly. Sticking with the earlier is usually the better option.
2014-11-08mark internal interfaces as hiddenDavid Kalnischkies
We have a bunch of classes which are of no use for the outside world, but were still exported and so needed to preserve ABI/API. Marking them as hidden to not export them any longer is a big API break in theory, but in practice nobody is using them – as if they would its a bug.
2014-09-27drop stored StringItems in favor of in-memory mappingsDavid Kalnischkies
Strings like Section names or architectures are needed vary often. Instead of writing them each time we need them, we deploy sharing for these special strings. Until now, this was done with a linked list of strings in which we would search, which was stored in the cache. It turns out we can do this just as well in memory as well with a bunch of std::map's. In memory means here that it isn't available anymore if we have a partly invalid cache, but that isn't much of a problem in practice as the status file is compared to the other files we parse very small and includes mostly duplicates, so the space we would gain by storing is more or less equal to the size of the stored linked list…
2014-06-18cleanup datatypes mix used in binary cacheDavid Kalnischkies
We had a wild mixture of (unsigned) int, long and long long here without much sense, so this commit adds a few typedefs to get some sense in the typesystem and ensures that a ID isn't sometimes computed as int, stored as long and compared with a long long… as this could potentially bite us later on as the size of the archive only increases over time.

Git-Dch: Ignore Reported-By: gcc -Wsuggest-attribute={pure,const,noreturn}
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)

2012-06-16do not dereference the storage for the unique strings as the pointer canDavid Kalnischkies
change at the time of writing the strings, so first store it temporary and then save the index in the (possibily new) pointer location
2012-04-23* edsp/edspsystem.cc:David Kalnischkies
- check with RealFileExists for scenario file as otherwise a directory like one provided with RootDir triggers the usage of EDSP
2011-12-15atleast libapt should announce to itself that it is clean…David Kalnischkies
(and be it if it tries to announce that…)
2011-12-13revert 2184.1.3: forward declaration instead of headersDavid Kalnischkies
The breakage is just to big for now, so guard the change with #ifndef APT_8_CLEANER_HEADERS and be nice to library users
2011-12-10* apt-pkg/contrib/fileutl.{h,cc}:David Kalnischkies
- implement a ModificationTime method for FileFd
2011-09-19use forward declaration in headers if possible instead of includesDavid Kalnischkies
2011-09-19do not pollute namespace in the headers with using (Closes: #500198)David Kalnischkies
2011-09-13reorder includes: add <config.h> if needed and include it at firstDavid Kalnischkies
2011-06-08add some more dpointer placeholdersMichael Vogt
2011-05-02parse correctly the Hold: lines into Pkg->SelectedState = HoldDavid Kalnischkies
2011-03-31rename edspwriter to straight edsp in toplevel as it does more thanDavid Kalnischkies
just writing stuff… it also reads and can work for both: - APT talking to an external solver - an external solver (understanding EDSP) talking to APT
2011-03-31add the methods we will need to write to make working with EDSP possibleDavid Kalnischkies
2011-03-31strip the Dir::state from the config name as it will never be thereDavid Kalnischkies
2011-03-31parse the state of the package from the scenario file correctlyDavid Kalnischkies
2011-03-31rename the 'universe' to 'scenario' to reflect the naming in the draftDavid Kalnischkies
2011-03-31add a special scenario filename for using stdinDavid Kalnischkies
2011-03-30be able to write solutions, tooDavid Kalnischkies
2011-03-30add a first round of stuff needed for talking between APT and solversDavid Kalnischkies
based on a very early draft for EDSP by Stefano APT can now write a scenario as well as load most stuff from it.
