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.
2014-06-18increase hashtable size for packages/groups by factor 5David Kalnischkies
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).

This is a internal struct not a external interface so the actual breakage should be small.

2014-05-10invalid cache if architecture set doesn't matchDavid Kalnischkies
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

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

2013-07-11Version 3 for DPkg::Pre-Install-Pkgs with MultiArch infoDavid Kalnischkies
Adds on top of Version 2 to all displayed version numbers the architecture as well as the MultiArch flag for consumption by the hooks. Most of the time the architecture will be the same for both versions displayed, but packages might change from "all" to "any" (or back) between versions so we can't display the architecture for packages. Pseudo-Format for Version 3: <name> <version> <arch> <m-a-flag> <compare> <version> <arch> <m-a-flag> Examples: stuff - - none < 1 amd64 none **CONFIGURE** libsame 1 i386 same < 2 i386 same **CONFIGURE** stuff 2 i386 none > 1 i386 none **CONFIGURE** libsame 2 i386 same > - - none **REMOVE** toolkit 1 all foreign > - - none **REMOVE** Closes: #712116

2011-03-08Remove the "pseudopackage" handling of Architecture: all packages forDavid Kalnischkies
Multi-Arch; instead, Arch: all packages only satisfy dependencies for the native arch, except where the Arch: all package is declared Multi-Arch: foreign. (Closes: #613584) This has the sideeffect that arch:all packages internally show up as coming from the native arch - so packages with the architecture "all" doesn't exist any longer in the pkgcache
