In ce1f3a2c we started warning about failing unlinking, which we
consistently do for directories. That isn't a problem as directories
usually aren't in the places we do want to clean up – with the potential
exeception of "lost+found", so lets ignore it like we ignore our own
partial/ subdirectory.

space-gapping: '-o option= value'
That is a very old feature (straight from 1998), but it is super
surprising if you try setting empty values and instead get error
messages or a non-empty value as the next parameter is treated as the
value – which could have been empty, so if for some reason you need a
compatible way of setting an empty value try: '-o option="" ""'.
I can only guess that the idea was to support '-o option value', but we
survived 17 years without it, we will do fine in the future I guess.
Similar is the case for '-t= testing' even through '-t testing' existed
before and the code even tried to detect mistakes like '-t= -b' … all
gone now.
Technically that is as its removing a feature replacing it with another
a major interface break. In practice I really hope for my and their
sanity that nobody was using this; but if for some reaon you do: Remove
the space and be done.
I found the patch and the bugreport actually only after the fact, but
its reassuring that others are puzzled by this as well and hence a
thanks is in perfect order here as the patch is practical identical
[expect that this one here adds tests and other bonus items].
Thanks: Daniel Hartwig for initial patch.

In 0940230d we started dropping privileges for file (and a bit later for
copy, too) with the intend of uniforming this for all methods. The
commit message says that the source will likely fail based on the
compressors already – and there isn't much secret in the repository
content. After all, after apt has run the update everyone can access the
content via apt anyway…
There are sources through which worked before which are mostly
single-deb (and those with the uncompressed files available).
The first one being especially surprising for users maybe, so instead of
failing, we make it so that apt detects that it can't access a source as
_apt and if so doesn't drop (for all sources!) privileges – but we limit
this to file/copy, so the uncompress which might be needed will still
fail – but that failed before this regression.
We display a notice about this, mostly so that if it still fails (e.g.
compressed) the user has some idea what is wrong.

Notices are just hints, but if they are printed in tests, they should be
expected and if not the test should fail. No current test has this
problem, so that is just potential future proving.

AI_IDN is a glibc extension, but we can worry about this at the time
actually anyone is seriously trying apt on non-glibc systems.

This 'ignores' the component Release files you can find in Debian
alongside the binary-* directories, which isn't exactly a common
usecase, but it worked before, so lets support it again as this isn't
worse than a valid Release file which is unsigned.

A slightly unlikely bug, but lets fix it while slightly reworking this
whole function to be slightly saner to look at, even if still not good.

Allows users who know what they are getting themselves into with this
trick to e.g. disable privilege dropping for e.g. file:// until they can
fix up the permissions on those repositories. It helps also the test
framework and people with a similar setup (= me) to run in less modified
environments.
|
|
Continueing on the track of dropping privileges in all methods, lets
drop it in copy, too, as the reasoning for it is very similar to file
and the interaction between the too quiet interesting as copy kinda
surfed as a fallback for file not being able to read the file. Both now
show a better error message as well as it was previously claiming to
have a hashsum mismatch, given that it couldn't read the file.

This flags is generally handy to avoid having to deal with ipv6 results on an
ipv4-only system, but it prevents e.g. the testcases from working if the
testsystem has no configured address at the moment (expect loopback), so
allow it to be sidestepped and let the testcases sidestep it.

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.

The wrapping will fail in the best case and actually end up deleting
/dev/null in the worst case. Given that there is no point in trying to
write atomically to /dev/null as you can't read from it again just
ignore these flags if higher level code ends up trying to use them on
/dev/null.

Leading or trailing newlines can be confusing for our parser as it
expects two newlines to start/stop a new stanza. To solve this the lines
we wanna add are printed first, ignore any leading newlines and then add
the stanza as provided by dpkg-deb with or without trailing newlines as
the parser will look at the first stanza only anyway and removing
trailing newlines is considerably harder to do.

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.

In the meantime the strange warnings disappeared, so we can get back to
showing them – and fix the one occurance which creeped in in the
meantime.

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

Removals in the acquire progress can be pretty important, so a failure
should be silently ignored, so we wrap our unlink call in a slightly
more forgiving wrapper checking things.

The general idea is: A small paragraph on the tool itself as a
description, a list of the most used (!= all) commands available in the
tool, a remark where to find more information on the tool and its
commands (aka: in the manpage) and finally a common block referring to
even more manpages. In exchange options are completely omitted from the
output as well as deprecated or obscure commands. (Better) Information
about them is available in the manpages anyway and the few options which
were listed before were also the least interesting ones (-o -c -q and co
are hardly of interest for someone totally new looking to find info by
asking for help and anyone with a bit of experience doesn't need this
short list. Those would need a list of options applying to the command
they call, but they are too numerous and command specific to list them
sanely in this context.

We can't for compatibility reasons in apt-cache, but apt can.

apt is supposed to be a user-friendly interface, so while these commands
are usually poweruser material and therefore do not need to be shown in
general introduction manpages/help messages its of no use to not allow
users to use them.
This includes clean, autoclean, build-dep, source, download, changelog,
depends, rdepends and showsrc – it doesn't include more non-interactive
commands like dump or xvcg as those are usually used by scripts if at
all.

-q is for logging and -qqq (old -qq) basically kills every output expect
errors, so there should be a way of declaring a middleground in which
the output of e.g. 'update' isn't as verbose, but still shows some
things. The test framework was actually making use of by accident as it
ignored the quiet level in output setup for apt before.
Eventually we should figure out some better quiet levels for all tools…

That is one huge commit with busy work only: Help messages used to be
one big translateable string, which is a pain for translators and hard
to reuse for us. This change there 'explodes' this single string into
new string for each documented string trying hard to split up the
translated messages as well. This actually restores many translations as
previously adding a single command made all of the bug message fuzzy.
The splitup also highlighted that its easy to forget a line, duplicate
one and similar stuff.

apt is an interactive command and the reasons we haven't this option set
for everything is mostly in keeping compatibility for a little while
longer to allow scripts to be changed if need be.

The show commands have different styles in both binaries as the audience
is potentially very different, but that doesn't mean we need to separate
the implementation especially as they are slightly similar. This also
allows us to switch between the different show versions at runtime via
an option.

Especially with apt now, it can be useful to set an option only for apt
and not for apt-get. Using a binary-specific subtree which is merged into
the root seems like a simple enough trick to achieve this.

The bugreport is more conservative in asking for a conditional, but
given that this is a message intended to be read by users to be run by
users we should suggest using a command intended to be used by users.
And while we are at, add sudo to the message – conditional of course.

The manpage is also slightly updated to work better as a central hub to
push people from all angles into the right directions without writting a
book disguised as an error message.

Insecure (aka unsigned) repositories are bad, period. We want to get
right of them finally and as a first step we are printing scary
warnings. This is already done, this commit just changes the messages to
be more consistent and prevents them from being displayed if
authenticity is guaranteed some other way (as indicated with
trusted=yes).
The idea is to first print the pure fact like "repository isn't signed"
as a warning (and later as an error), while giving an explaination in a
immediately following notice (which is displayed only in quiet level 0:
so in interactive use, not in scripts and alike).

Detecting network errors has some benefits in the acquire system as if
we can't connect to a host trying it for a million files is pointless.
http and co which use connect.cc deal with this, but https which uses
curl had connection failures as "normal" errors which could potentially
be worked around (like trying Release instead of the failed InRelease).

The main part is refactoring through to allow hiding the magic needed to

Showing just "Get: [1234 B]" looks very strange, so we now print the

Commit 653ef26c70dc9c0e2cbfdd4e79117876bb63e87d broke the camels back in
sofar that everything works in terms of our internal use of copy:/, but
external use is completely destroyed. This is kinda the reverse of what
happened in "parallel" in the sid branch, where external use was mostly
fine, internal and external exploded on the GzipIndexes option.
We fix this now by rewriting our internal use by letting copy:/ only do
what the name suggests it does: Copy files and not uncompress them
on-the-fly. Then we teach copy and the uncompressors how to deal with
/dev/null and use it as destination file in case we don't want to store
the uncompressed files on disk.

dpkg-checkbuilddeps changed its exitcodes in the recent past so the
old check always fails now skipping the test. Lets try a slightly more
stable (at least assume it to be) variant of detecting this.

We drop it in decompressors, which are the natural next step, so if an
archive is used which isn't worldreadable (= not accessible by _apt) it
doesn't work anyway, so we just fail a bit earlier now and avoid all the
bad things which can happen over file (which could very well still be a
network resourc via NFS mounts or similar stuff, so hardly as safe as
the name might suggest at first).
