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.

We have a bunch of classes which are of no use for the outside world,
but were still exported and so needed to preserve ABI/API. Marking them
as hidden to not export them any longer is a big API break in theory,
but in practice nobody is using them – as if they would its a bug.

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…

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.

Beside being a bit cleaner it hopefully also resolves oddball problems
I have with high levels of parallel jobs.

change at the time of writing the strings, so first store it temporary
and then save the index in the (possibily new) pointer location
|
|
- check with RealFileExists for scenario file as otherwise a directory
like one provided with RootDir triggers the usage of EDSP
|
|
(and be it if it tries to announce that…)
|
|
The breakage is just to big for now, so guard the change with
#ifndef APT_8_CLEANER_HEADERS and be nice to library users
|
|
- implement a ModificationTime method for FileFd

just writing stuff… it also reads and can work for both:
- APT talking to an external solver
- an external solver (understanding EDSP) talking to APT

based on a very early draft for EDSP by Stefano
APT can now write a scenario as well as load most stuff from it.
