2016-06-05refactor EDSP classes for better internal reuseDavid Kalnischkies
The classes are all marked as hidden, so changing them is no problem ABI wise and will help with introducing protocols similar to EDSP. The change has no observeable behavior difference, its just code juggling. Git-Dch: Ignore
2016-06-04edsp: use an ID mapping for the internal solverDavid Kalnischkies
Currently an EDSP solver gets send basically all versions which means the absolute count is the same, but that might not be true forever (and with the skipping of rc-only versions it kinda is already) and even if it were true, segfaulting on bad input seems wrong.
2016-01-26remove unused Description methods in listparsersDavid Kalnischkies
These virtual methods are implemented in hidden classes, so we can drop them without breaking the ABI. Git-Dch: Ignore
2015-11-04wrap every unlink call to check for != /dev/nullDavid Kalnischkies
Unlinking /dev/null is bad, we shouldn't do that. Also, we should print at least a warning if we tried to unlink a file but didn't manage to pull it of (ignoring the case were the file is /dev/null or doesn't exist in the first place). This got triggered by a relatively unlikely to cause problem in pkgAcquire::Worker::PrepareFiles which would while temporary uncompressed files (which are set to keep compressed) figure out that to files are the same and prepare for sharing by deleting them. Bad move. That also shows why not printing a warning is a bad idea as this hide the error for in non-root test runs. Git-Dch: Ignore
2015-11-04sanify API to get 'the' candidate versionDavid Kalnischkies
This was discussed a while ago on #debian-apt and now that I see myself making this mistake lets bite the bullet and fix it in the easy way out version: Using a new name which fits with a similar named setter and deprecate the old method instead of 'hostily' changing API. Closes: #803471
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.

2015-08-10parse packages from all architectures into the cacheDavid Kalnischkies
Now that we can dynamically create dependencies and provides as needed rather than requiring to know with which architectures we will deal before running we can allow the listparser to parse all records rather than skipping records of "unknown" architectures. This can e.g. happen if a user has foreign architecture packages in his status file without dpkg knowing about this architecture (or apt configured in this way). A sideeffect is that now arch:all packages are (correctly) recorded as available from any Packages file, not just from the native one – which has its downsides for the resolver as mixed-arch source packages can appear in different architectures at different times, but that is the problem of the resolver and dealing with it in the parser is at best a hack (and also depends on a helpful repository). Another sideeffect is that his allows :none packages to appear in Packages files again as we don't do any kind of checks now, but given that they aren't really supported (anymore) by anyone we can live with that.
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. Git-Dch: Ignore
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.
