2015-06-15populate the Architecture field for PackageFilesDavid Kalnischkies
This is mainly visible in the policy, so that you can now pin by b= and let it only effect Packages files of this architecture and hence the packages coming from it (which do not need to be from this architecture, but very likely are in a normal repository setup). If you should pin by architecture in this way is a different question… Closes: 687255
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.

2014-10-03rename StringType VERSION to VERSIONNUMBERDavid Kalnischkies
aptitude has a define for VERSION, so to not generate a FTBFS we just rename our enum element to a slightly less generic name. Git-Dch: Ignore

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.
2014-05-09parse and retrieve multiple Descriptions in one recordDavid Kalnischkies
It seems unlikely for now that proper archives will carry multiple Description-* stanzas in the Packages (or Translation-*) file, but sometimes apt eats its own output as shown by the usage of the CD team and it would be interesting to let apt output multiple translations e.g. in 'apt-cache show'.
2014-03-21mark optional (private) symbols as hiddenDavid Kalnischkies
This methods should not be used by anyone expect the library itself as they are helpers for the specific class and therefore perfect candidates for hidding. Git-Dch: Ignore
2014-03-13abstract version hash comparison a bitDavid Kalnischkies
In #737085 we see that apt can be confused if informations about versions only differ slightly. This commit adds a way of at least adding a few more data points with the next abi break to help a bit with it. Git-Dch: Ignore

2013-04-03share version strings between same versions (of different architectures)David Kalnischkies
to save some space and allow quick comparisions later on
2013-03-13factor version string creation out of NewDepends, so we can easily reuseDavid Kalnischkies
version strings e.g. for implicit multi-arch dependencies
2011-10-12add implicit dependencies needed for Multi-Arch at the time a VersionDavid Kalnischkies
struct is created and not at the end of the cache generation This allows us to be independent from the configured architectures for these kind of conflicts, we get natural progress for free and only the needed dependencies are in th respective binary cache.

- add and document APT::Cache-{Start,Grow,Limit} options for mmap control
2010-07-08* apt-pkg/pkgcachegen.{cc,h}:David Kalnischkies
- make the used MMap moveable (and therefore dynamic resizeable) by applying (some) mad pointer magic (Closes: #195018)
2010-07-08use references instead of copies in the Cache generation methodsDavid Kalnischkies
2010-07-06wrap the mmap actions in the CacheGenerator in their own methods toDavid Kalnischkies
be able to react on condition changes later then we can move mmap
2010-06-04* apt-pkg/cachefile.{cc,h}:David Kalnischkies
- split Open() into submethods to be able to build only parts - make the OpProgress optional in the Cache buildprocess

the information from the parent package now
2009-12-27Split ListParser::NewDepends into two methods to use these new methodDavid Kalnischkies
for creating the dependencies needed for our groups: For now for all groups only one package can be installed at the same time which conflicts with each other packages in the group. The exceptions are architecture all package. Also, the Multi-Arch field is now parsed, but not used for now.
2009-12-19Implement the first step toward Multi-Arch by setting up a GroupDavid Kalnischkies
infrastructor for packages. APT is now aware of the fact that a package A in architecture X can't satisfy a dependency on package A in architecture Y - to handle these packages are now identified by name and architecture, so different architectures of the same package are handled internally as completly different packages. This is great for pinning, dependency checking and in many other situations, but sometimes we need to know which archs are available for a given package: Here Groups come to our rescue!
