support regex and co in 'apt-cache policy $pkg' again

2015-12-14T01:38:34Z

Regression of 1e064088bf7b3e29cd36d30760fb3e4143a1a49a (1.1~exp4) which moved code around and renamed methods heavily ending up calling the wrong method matching packagenames only instead of calling the full array. Most commands work with versions, so this managed to fly under the radar for quite a while. Closes: 807870

support .deb files in upgrade operations as well

2015-11-04T17:04:01Z

The main part is refactoring through to allow hiding the magic needed to support .deb files in deeper layers of libapt so that frontends have less exposure to Debian specific classes like debDebPkgFileIndex.

implement dpkgs vision of interpreting pkg: dependencies

2015-09-14T13:22:18Z

How the Multi-Arch field and pkg: dependencies interact was discussed at DebConf15 in the "MultiArch BoF". dpkg and apt (among other tools like dose) had a different interpretation in certain scenarios which we resolved by agreeing on dpkg view – and this commit realizes this agreement in code. As was the case so far libapt sticks to the idea of trying to hide MultiArch as much as possible from individual frontends and instead translates it to good old SingleArch. There are certainly situations which can be improved in frontends if they know that MultiArch is upon them, but these are improvements – not necessary changes needed to unbreak a frontend. The implementation idea is simple: If we parse a dependency on foo:amd64 the dependency is formed on a package 'foo:amd64' of arch 'any'. This package is provided by package 'foo' of arch 'amd64', but not by 'foo' of arch 'i386'. Both of those foo packages provide each other through (assuming foo is M-A:foreign) to allow a dependency on 'foo' to be satisfied by either foo of amd64 or i386. Packages can also declare to provide 'foo:amd64' which is translated to providing 'foo:amd64:any' as well. This indirection over provides was chosen as the alternative would be to teach dependency resolvers how to deal with architecture specific dependencies – which violates the design idea of avoiding resolver changes, especially as architecture-specific dependencies are a cornercase with quite a few subtil rules. Handling it all over versioned provides as we already did for M-A in general seems much simpler as it just works for them. This switch to :any has actually a "surprising" benefit as well: Even frontends showing a package name via .Name() [which doesn't show the architecture] will display the "architecture" for dependencies in which it was explicitely requested, while we will not show the 'strange' :any arch in FullName(true) [= pretty-print] either. Before you had to specialcase these and by default you wouldn't get these details shown. The only identifiable disadvantage is that this complicates error reporting and handling. apt-get's ShowBroken has existing problems with virtual packages [it just shows the name without any reason], so that has to be worked on eventually. The other case is that detecting if a package is completely unknown or if it was at least referenced somewhere needs to acount for this "split" – not that it makes a practical difference which error is shown… but its one of the improvements possible.

use c++11 algorithms to avoid strange compiler warnings

2015-08-29T10:33:30Z

Nobody knows what makes the 'unable to optimize loop' warning to appear in the sourceslist minus-options parsing, especially if we use a foreach loop, but we can replace it with some nice c++11 algorithm+lambda usage, which also helps in making even clearer what happens here. And as this would be a lonely change, lets do it for a few more loops as well where I might or might not have seen the warning at some point in time, too. Git-Dch: Ignore

cacheset: Prefer the depcache over the policy again

2015-08-27T11:13:13Z

By preferring the policy over the depcache, we ignore any changes we made in the depcache, which makes it impossible for code to change the candidate used here. This basically reverts commit 2fbfb111312257fa5fc29b0c2ed386fb712f960e: prefer the Policy if it is built instead of the DepCache and if DepCache is not available as fallback built the Policy But it also cleans the code up a bit, by removing one level of nesting.

avoid virtual in the iterators

2015-08-10T15:27:18Z

With a bit of trickery and the Curiously recurring template pattern we can free us from our use of virtual in the iterators were it is unneeded bloat as we never deal with pointers to iterators and similar such. Git-Dch: Ignore

show or-groups in not-installed recommends and suggests lists

2015-08-10T15:27:18Z

Further abstracting our new ShowList allows to use it for containers of strings as well giving us the option to implement an or-groups display for the recommends and suggests lists which is a nice trick given that it also helps with migrating the last remaining other cases of old ShowList.

make all d-pointer * const pointers

2015-08-10T15:25:25Z

Doing this disables the implicit copy assignment operator (among others) which would cause hovac if used on the classes as it would just copy the pointer, not the data the d-pointer points to. For most of the classes we don't need a copy assignment operator anyway and in many classes it was broken before as many contain a pointer of some sort. Only for our Cacheset Container interfaces we define an explicit copy assignment operator which could later be implemented to copy the data from one d-pointer to the other if we need it.

add d-pointer, virtual destructors and de-inline de/constructors

2015-06-16T14:22:46Z

To have a chance to keep the ABI for a while we need all three to team up. One of them missing and we might loose, so ensuring that they are available is a very tedious but needed task once in a while. Git-Dch: Ignore
