The value of Origin, Label, Codename and co can be used in user
configuration from apts own pinning to unattended upgrades.
A repository changing this values can therefore have serious effects on
the behaviour of apt and other tools using these values.
In a first step we will generate error messages for these changes now
explaining the need for explicit confirmation and provide config options
and commandline flags to accept them.

If we couldn't find an entry for a Sources file we would generate an
error while for a Packages file we would silently skip it due to
assuming it is missing because it is empty. We can do better by checking
if the repository declares that it supports a component we want to get
the file from and if not say so and hint at the user making a typo.
An example were this helps is mozilla.debian.net which dropped the
firefox-aurora component (as upstream did) meaning no upgrades until the
user notices manually that the repository doesn't provide packages
anymore. With this commit warnings are raised hopefully causing the user
to investigate what is wrong (sooner).

Debian has a Packages file for arch:all already, but the arch:any files
contain arch:all packages as well, so downloading it would be a total
waste of resources. Getting this solved is on the list of things to do,
but it is also the hardest part – for index targets like Contents the
situation is much easier and less server/client implementations are
involved so we might not want to stall them.
A repository can now declare via:
No-Support-for-Architecture-all: Packages
that even if an arch:all Packages exists, it shouldn't be downloaded, so
that support for Contents files can be added now.
See also 1dd20368486820efb6ef4476ad739e967174bec4 for the implementation
of downloading arch:all index targets, which this is limiting.
The field uses the name of the target from the apt configuration for
simplicity and is negative by design as this field is intended to be
supported/needed only for a "short" time (one or two Debian releases).
While this commit theoretically supports any target, its expected to
only see "Packages" as a value in reality.

Based on a discussion with Niels Thykier who asked for Contents-all this
implements apt trying for all architecture dependent files to get a file
for the architecture all, which is treated internally now as an official
architecture which is always around (like native). This way arch:all
data can be shared instead of duplicated for each architecture requiring
the user to download the same information again and again.
There is one problem however: In Debian there is already a binary-all/
Packages file, but the binary-any files still include arch:all packages,
so that downloading this file now would be a waste of time, bandwidth
and diskspace. We therefore need a way to decide if it makes sense to
download the all file for Packages in Debian or not. The obvious answer
would be a special flag in the Release file indicating this, which would
need to default to 'no' and every reasonable repository would override
it to 'yes' in a few years time, but the flag would be there "forever".
Looking closer at a Release file we see the field "Architectures", which
doesn't include 'all' at the moment. With the idea outlined above that
'all' is a "proper" architecture now, we interpret this field as being
authoritative in declaring which architectures are supported by this
repository. If it says 'all', apt will try to get all, if not it will be
skipped. This gives us another interesting feature: If I configure a
source to download armel and mips, but it declares it supports only
armel apt will now print a notice saying as much. Previously this was a
very cryptic failure. If on the other hand the repository supports mips,
too, but for some reason doesn't ship mips packages at the moment, this
'missing' file is silently ignored (= that is the same as the repository
including an empty file).
The Architectures field isn't mandatory through, so if it isn't there,
we assume that every architecture is supported by this repository, which
skips the arch:all if not listed in the release file.

History suggests that this comes from an earlier apt-secure
implementation, but never really became a thing, totally unused and
marked as deprecated for "ages" now. Especially as it did nothing even
if it would have been used (libapt itself didn't use it at all).
|
|
Limits which key(s) can be used to sign a repository. Not immensely useful
from a security perspective all by itself, but if the user has
additional measures in place to confine a repository (like pinning) an
attacker who gets the key for such a repository is limited to its
potential and can't use the key to sign its attacks for an other (maybe
less limited) repository… (yes, this is as weak as it sounds, but having
the capability might come in handy for implementing other stuff later).

indexRecords was used to parse the Release file – mostly the hashes –
while metaIndex deals with downloading the Release file, storing all
indexes coming from this release and … parsing the Release file, but
this time mostly for the other fields.
That wasn't a problem in metaIndex as this was done in the type specific
subclass, but indexRecords while allowing to override the parsing method
did expect by default a specific format.
APT isn't really supporting different types at the moment, but this is
a violation of the abstraction we have everywhere else and, which is the
actual reason for this merge: Options e.g. coming from the sources.list
come to metaIndex naturally, which needs to wrap them up and bring them
into indexRecords, so the acquire system is told about it as they don't
get to see the metaIndex, but they don't really belong in indexRecords
as this is just for storing data loaded from the Release file… the
result is a complete mess.
I am not saying it is a lot prettier after the merge, but at least
adding new options is now slightly easier and there is just one place
responsible for parsing the Release file. That can't hurt.
|
|
A specific trust state can be enforced via a sources.list option, but it
effects all entries handled by the same Release file, not just the entry
it was given on so we enforce acknowledgement of this by requiring the
same value to be (not) set on all such entries.
|

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.

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.

Selecting targets based on the Release they belong to isn't to
unrealistic. In fact, it is assumed to be the most used case so it is
made the default especially as this allows to bundle another thing we
have to be careful with: Filenames and only showing targets we have
acquired.

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 need a general way to get from a sources.list entry to IndexTargets
and with this change we can move from pkgSourceList over the list of
metaIndexes it includes to the IndexTargets each metaIndex can have.

We can't add a new virtual method without breaking the ABI, but we can
freely add new methods, so for older ABIs we just implement this method
with a dynamic_cast, so that clients can be more ignorant about the API
here and especially don't need to pull a very dirty trick by assuming
internal knowledge (like apt-get did here).

- add trusted=yes option to mark unsigned (local) repository as trusted
based on a patch from Ansgar Burchardt, thanks a lot! (Closes: #596498)
Note that "apt-get update" still warns about unknown signatures even
when [trusted=yes] is given for the source.

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).
