Our implementation of wildcards was rudimentary. It worked for some
common ones, but it was also broken: For example, armel matched any-armel,
but should match any-arm.
With this commit, we load the correct tables from dpkg. Supported are
both triplets and quadruplet tables (the latter introduced in dpkg 1.18.11).
There are some odd things we have to deal with in the cache filter for
historical and API reasons:
* The character "*" must be accepted as an alternative to any - in fact
it may appear anywhere in the wildcard as we also allow fnmatch() style
wildcard matching on the commandline.
* The code might get passed an arch with a minus at the end, for example
the cmdline "install apt:any-arm-" will first try to check if any-arm-
is a valid architecture. We deal with this by rejecting any wildcard
ending in a minus.
* Triplets are actually implemented by extending them to faux quadruplets
- by prepending a "base" component for the architecture tuple, and "any"
if there is a wildcard component.
Once we have constructed a wildcard, it is transformed into an fnmatch()
expression for historical reasons. In the future, we should really get a
tuple class and implement matching in a better, more explicit way.
This does for now though - it passes all the test cases and accepts all
things it should accept.
Closes: #748936

The idea is simple: Each¹ Find*( call starts with a call check if the
given option (with the requested type) exists in the whitelist. The
whitelist is specified via our configure-index file so that we have
a better chance at keeping it current. the whitelist is loaded via a
special (undocumented for now) configuration stanza and if none is
loaded the empty whitelist will make it so that no warnings are shown.
Much needs to be done still, but that is as good a time as any to take a
snapshot of the current state and release it into the wild given that it
found some bugs already and has no practical effect on users.
¹ not all in this iteration, but many

You can pretty much achieve the same with a local dummy package if you
want to, but libapt has an inbuilt setting for essential: "apt" which
can be overridden with this option as well – it could be helpful in
quick tests and what not so adding this alternative shouldn't really
hurt much.
We aren't going to document them much through as care must be taken in
regards to the binary caches as they aren't invalidated by config
options alone, so the effects of old settings could still be in them,
similar to the other already existing pkgCacheGen option(s).

libapt allows to configure compressors to be used by its system via
configuration implemented in 03bef78461c6f443187b60799402624326843396,
but that was never really documented and also only partly working, which
also explains why the tests weren't using it…

This should make it more obvious that CHANGEPATH is a placeholder which
apt will replace with a package specific path rather than a string
constant.

Provided is a specialized acquire item which given a version can figure
out the correct URI to try by itself and if not provides an error
message alongside with static methods to get just the URI it would try
to download if it should just be displayed or similar such.
The URI is constructed as follows:
Release files can provide an URI template in the "Changelogs" field,
otherwise we lookup a configuration item based on the "Label" or
"Origin" of the Release file to get a (hopefully known) default value
for now. This template should contain the string CHANGEPATH which is
replaced with the information about the version we want the changelog
for (e.g. main/a/apt/apt_1.1). This middleway was choosen as this path
part was consistent over the three known implementations (+1 defunct),
while the rest of the URI varies widely between them.
The benefit of this construct is that it is now easy to get changelogs
for Debian packages on Ubuntu and vice versa – even at the moment where
the Changelogs field is present nowhere. Strictly better than what
apt-get had before as it would even fail to get changelogs from
security… Now it will notice that security identifies as Origin: Debian
and pick this setting (assuming again that no Changelogs field exists).
If on the other hand security would ship its changelogs in a different
location we could set it via the Label option overruling Origin.

The configuration key Acquire::AllowInsecureRepositories controls if
apt allows loading of unsigned repositories at all.
The configuration Acquire::AllowDowngradeToInsecureRepositories
controls if a signed repository can ever become unsigned. This
should really never be needed but we provide it to avoid having
to mess around in /var/lib/apt/lists if there is a use-case for
this (which I can't think of right now).

- replace CDROM with the proper CD-ROM in text
|
|
|
|
- document APT::Architectures list (Closes: #612102)
|
|
- deal with missing FSTAB_DIR when using libudev to discover cdrom
- add experimental APT::cdrom::CdromOnly option (on by default).
When this is set to false apt-cdrom will handle any removable
deivce (like a usb-stick) as a "cdrom/dvd" source

essential flag:
* native is the default and will only mark packages of the main arch
* all will mark all packages which have these flag in Packages
* none will obviously do the opposite
* installed will only mark packages which are installed as essential,
so it will behave in the same way as dpkg does it.
It is mostly needed sometimes for debugging but some users with special
needs might like to switch the mode as well under the expense to be
on their own…
