* drop stored StringItems in favor of in-memory mappingsDavid Kalnischkies2014-09-271-28/+2
| | | | | | | | | | | | | | | 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…
* deprecate Pkg->Name in favor of Grp->NameDavid Kalnischkies2014-09-271-2/+5
| | | | | | | They both store the same information, so this field just takes up space in the Package struct for no good reason. We mark it "just" as deprecated instead of instantly removing it though as it isn't misleading like Section was and is potentially used in the wild more often.
* remove the Section member from package structDavid Kalnischkies2014-06-181-5/+0
| | | | | | | | | | | | | | | | | | A version belongs to a section and has hence a section member of its own. A package on the other hand can have multiple versions from different sections. This was "solved" by using the section which was parsed first as order of sources.list defines, but that is obviously a horribly unpredictable thing. We therefore directly remove this struct member to free some space and mark the access method as deprecated, which is told to return the section of the 'newest' known version, which is at least predictable, but possible not what it returned before – but nobody knows. Users are way better of with the Section() as returned by the version they are dealing with. It is likely the same for all versions of a package, but in the few cases it isn't, it is important (like packages moving from main/* to contrib/* or into oldlibs …).
* cleanup datatypes mix used in binary cacheDavid Kalnischkies2014-06-181-89/+101
| | | | | | | | 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.
* increase hashtable size for packages/groups by factor 5David Kalnischkies2014-06-181-6/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It also makes the size configureable, so it can be adapted in the future without the need for an abi break - and even by users… The increase was long overdue as it gives a >10% decrease in runtime of e.g. 'apt-get check -s'. Some (useless) benchmark with 69933 groups and 187796 packages without a pre-built cache: time apt-get check -so APT::Cache-HashTableSize=1 → 20m time apt-get check -so APT::Cache-HashTableSize=1000 → 6,41s time apt-get check -so APT::Cache-HashTableSize=2000 → 5,64s (old) time apt-get check -so APT::Cache-HashTableSize=3000 → 5,30s time apt-get check -so APT::Cache-HashTableSize=5000 → 5,08s time apt-get check -so APT::Cache-HashTableSize=6000 → 5,05s time apt-get check -so APT::Cache-HashTableSize=7000 → 5,02s time apt-get check -so APT::Cache-HashTableSize=8000 → 5,00s time apt-get check -so APT::Cache-HashTableSize=9000 → 4,98s time apt-get check -so APT::Cache-HashTableSize=10000 → 4,96s (new) time apt-get check -so APT::Cache-HashTableSize=15000 → 4,90s time apt-get check -so APT::Cache-HashTableSize=20000 → 4,86s time apt-get check -so APT::Cache-HashTableSize=30000 → 4,77s time apt-get check -so APT::Cache-HashTableSize=40000 → 4,74s time apt-get check -so APT::Cache-HashTableSize=50000 → 4,73s time apt-get check -so APT::Cache-HashTableSize=60000 → 4,71s The gap increases further for operations which have more package lookups. Factor 5 was chosen as higher values do not provide any really significant timing advantage anymore compared to the memory increase in my testing and there is always the possibility to increase it now if that changes. (also most users will not have 3 releases and 4 architectures in the cache, so theirs will be much smaller and faster).

* | invalid cache if architecture set doesn't matchDavid Kalnischkies2014-05-101-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The cache heavily depends on the architecture(s) it is build for, especially if you move from single- to multiarch. Adding a new architecture to dpkg therefore has to be detected and must invalidate the cache so that we don't operate on incorrect data. The incorrect data will prevent us from doing otherwise sensible actions (it doesn't allow bad things to happen) and the recovery is simple and automatic in most cases, so this hides pretty well and is also not as serious as it might sound at first. Closes: 745036

| | | | | | | | | Multi-Arch; instead, Arch: all packages only satisfy dependencies for the native arch, except where the Arch: all package is declared Multi-Arch: foreign.

* Add yet another pseudo package which isn't as pseudo as the others:David Kalnischkies2010-02-121-1/+1
| | | | | | | | | | Arch all packages are now represented by arch depending packages which all depend on a package with the same name and the special arch "all". This packages has NO dependencies, but beside this the same information. It is the only package which has a size, the arch depending ones all have a zero size. While the arch depending pseudo packages are used for dependency resolution the arch "all" package is used for downloading and ordering of the package.

| | | | | | | | | 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.
* Implement the first step toward Multi-Arch by setting up a GroupDavid Kalnischkies2009-12-191-5/+25
| | | | | | | | | | | | 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!
* Refactor the cache iterators by using a common base classDavid Kalnischkies2009-12-091-8/+1
