This improves performance of the cache generation on my
ARM platform (4x Cortex A15) by about 10% to 20% from
2.35-2.50 to 2.1 seconds.

More safety, less writeable memory.

This could allow an attacker to mark a package as installed in a
remote package index, as long as the package was not listed in
the dpkg status file.
This way, an attacker could force the installation of a package
during a dist-upgrade, by providing two packages in an index,
an older marked as installed, and a newer - apt would "upgrade"
to the newer version.

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.

Trade deduplication of code for a bunch of new virtuals, so it is
actually visible how the different indexes behave cleaning up the
interface at large in the process.

Expecting the worst is easy to code, but has its disadvantages e.g.
by creating package structures which otherwise would have never
existed. By creating the provides instead at the time a package
structure is added we are well prepared for the introduction of partial
architectures, massive amounts of M-A:foreign (and :allowed) and co as
far as provides are concerned at least. We have something relatively
similar for dependencies already.
Many tests are added for both M-A states and the code cleaned to
properly support implicit provides for foreign architectures and
architectures we 'just' happen to parse.

We aren't and we will not be really compatible again with the previous
stable abi, so lets drop these markers (which never made it into a
released version) for good as they have outlived their intend already.

C++11 adds the 'override' specifier to mark that a method is overriding
a base class method and error out if not. We hide it in the APT_OVERRIDE
macro to ensure that we keep compiling in pre-c++11 standards.

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.

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.

Reimplementing an inline method is opening a can of worms we don't want
to open if we ever want to us a d-pointer in those classes, so we do the
only thing which can save us from hell: move the destructors into the cc
sources and we are good.
Technically not an ABI break as the methods inline or not do the same
(nothing), so a program compiled against the old version still works
with the new version (beside that this version is still in experimental,
so nothing really has been build against this library anyway).

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.

Version/Architecture information in a Translation-$lang file is
not allowed, so don't try to parse it. This is a fix for a bugreport
where a Translation-en file contained the content of the regular
Packages file (probably due to local FS corruption). This lead to
strange error messages on file download.
Thanks to Thomas Reusch for the report.

It seems unlikely for now that proper archives will carry multiple
Description-* stanzas in the Packages (or Translation-*) file, but
sometimes apt eats its own output as shown by the usage of the CD team
and it would be interesting to let apt output multiple translations
e.g. in 'apt-cache show'.

This methods should not be used by anyone expect the library itself as
they are helpers for the specific class and therefore perfect candidates
for hidding.

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.

Build-dependencies are now able to include a <profile.foo …>
specification limiting usage similar to already supported [arch …].

based on a very early draft for EDSP by Stefano
APT can now write a scenario as well as load most stuff from it.
|
|
- create foo:any provides for all architectures for an allowed package
|
|
- enable StripMultiArch by default for ParseDepends
|
|
|
|
|
|
instead of distributed in a few methods
|
|
the information from the parent package now
|
|
patch which includes the following big changes:
- Declare the unused [vendor] field in sources.list as option field,
e.g. deb [arch=amd64,i386 lang=en_GB have=fun] http://example.org
- When fetching index files download them for all APT::Architectures
(overrideable with the options field above)
- Allow all architectures of APT::Architectures to be in the Cache
- Add the architecture to status and progress informations
- Add b= (Binary architecture) to policy
This commit doesn't incude the "pin-hack" as the Group structure will take
care of this (and does it already to some extend).

infrastructor for packages.
APT is now aware of the fact that a package A in architecture X can't
satisfy a dependency on package A in architecture Y - to handle these
packages are now identified by name and architecture, so different
architectures of the same package are handled internally as completly
different packages. This is great for pinning, dependency checking and
in many other situations, but sometimes we need to know which archs are
available for a given package: Here Groups come to our rescue!

for now as long we don't understand them (Closes: #558103)
