2015-09-14implement autobit and pinning in EDSP solver 'apt'David Kalnischkies
The parser creates a preferences as well as an extended states file based on the EDSP scenario file, which isn't the most efficient way of dealing with this as thes text files have to be parsed again by another layer of the code, but it needs the least changes and works good enough for now. The 'apt' solver is in the end just a test solver like dump.

2015-08-12policy: Be more strict about parsing pin files, and document prio 0Julian Andres Klode
Treat invalid pin priorities and overflows as an error. Closes: #429912
2015-08-12Add a parameter ConsiderFiles to GetPriority(VerIterator)Julian Andres Klode
This allows us to exclude files from being considered for the priority, so it will return only specific-version matches.
2015-08-11Simply ignore cruft in the status files, do not treat it as prio 0Julian Andres Klode
This was broken in case all other sources were < 0.

2015-08-10bring back deb822 sources.list entries as .sourcesDavid Kalnischkies
Having two different formats in the same file is very dirty and causes external tools to fail hard trying to parse them. It is probably not a good idea for them to parse them in the first place, but they do and we shouldn't break them if there is a better way. So we solve this issue for now by giving our deb822 format a new filename extension ".sources" which unsupporting applications are likely to ignore an can begin gradually moving forward rather than waiting for the unknown applications to catch up. Currently and for the forseeable future apt is going to support both with the same feature set as documented in the manpage, with the longtime plan of adopting the 'new' format as default, but that is a long way to go and might get going more from having an easier time setting options than from us pushing it explicitely.
2015-08-10make all d-pointer * const pointersDavid Kalnischkies
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.

2015-08-10policy: Fix the new policy implementation to handle downgrades correctlyJulian Andres Klode
This was broken previously, as we'd choose a downgrade when it's pin was higher than the previously selected candidate.
2015-08-10Determine the candidate based on per-version pins, instead of old codeJulian Andres Klode
The new implementation assigns each version a pin, instead of assigning the pin to a package. This enables us to give each version of a package a different priority. Closes: #770017 Closes: #622237 Closes: #620249 Closes: #685215
2015-08-10policy: Return highest file pin if version pin == 0 in GetPriority()Julian Andres Klode
This makes sure that we display a useful value instead of 0 for versions that are pinned due to package files.
2015-08-10policy: Assign per-version pinsJulian Andres Klode
2015-08-10pkgPolicy: Introduce storage and helpers for per-version pinsJulian Andres Klode
Per-version pins should lead to more predictable results with /etc/apt/preferences uses like pinning one version with -1.
2015-06-16add d-pointer, virtual destructors and de-inline de/constructorsDavid Kalnischkies
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
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.
2015-05-11remove unused and strange default-value for pinsDavid Kalnischkies
If the pin for a generic pin is 0, it get a value by strange looking rules, if the pin is specific the rules are at least not strange, but the value 989 is a magic number without any direct meaning… but both never happens in practice as the parsing skips such entries with a warning, so there always is a priority != 0 and the code therefore never used.
2015-05-11a pin of 1000 always means downgrade allowedDavid Kalnischkies
The documentation says this, but the code only agreed while evaluating specific packages, but not generics. These needed a pin above 1000 to have the same effect. The code causing this makes references to a 'second pesduo status file', but nowhere is explained what this might stand for and/or what it was, so we do the only reasonable thing: Remove all references and do as documented.

2013-08-08specific pins below 1000 cause downgradesDavid Kalnischkies
We start your quest by using the version of a package applying to a specific pin, but that version could very well be below the current version, which causes APT to suggest a downgrade even if it is advertised that it never does this below 1000. Its of course questionable what use a specific pin on a package has which has a newer version already installed, but reacting with the suggestion of a downgrade is really not appropriated (even if its kinda likely that this is actually the intend the user has – it could just as well be an outdated pin) and as pinning is complicated enough we should atleast do what is described in the manpage. So we look out for the specific pin and if we haven't seen it at the moment we see the installed version, we ignore the specific pin. Closes: 543966

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
