for some "interesting" reason gpg decides that it needs to update its
trustdb.gpg file in a --list-keys command even if right before gpg is
asked to --check-trustdb. That wouldn't be as bad if it wouldn't modify
the keyring being listed at that moment as well, which generates not
only warnings which are not a problem for us, but as the keyring
modified can be in /usr it modified files which aren't allowed to be
modified.
The suggested solution in the bugreport is running --check-trustdb
unconditionally in an 'apt-key update' call, but this command will not
be used in the future and this could still potentially bite us in
net-update or adv calls. All of this just to keep a file around, which
we do not need…
The commit therefore switches to the use of a temporary created
trusted.gpg file for everyone and asks gpg to not try to update the
trustdb after its intial creation, which seems to avoid the problem
altogether.
It is using your also faked secring btw as calling the check-trustdb
without a keyring is a lot slower …
Closes: #687611
Thanks: Andreas Beckmann for the initial patch!

APT doesn't care for the trustdb.gpg, but gnupg requires one even for
the simplest commands, so we either use the one root has available in
/etc or if we don't have access to it (as only root can read that file)
we create a temporary directory to store a trustdb.gpg in it.
We can't create just a temporary file as gpg requires the given
trustdb.gpg file to be valid (if it exists), so we would have to remove
the file before calling gnupg which would allow mktemp (and co) to hand
exactly this filename out to another program (unlikely, but still).

Usually, most apt-key commands require root, so the script is checking
for being run as root, but in your tests we use a non-root location, so
we don't need to be root and therefore need an option to skip the check.

While we don't want these error messages on our usual stack, we can use
our usual infrastructure to generate an error message with all the usual
bells like errno and strerror attached.

If this code is run as non-root we are in a special situation (e.g. in
our testcases) where it is obvious that we can't enforce user/group on
any file, so skip this code altogether instead of bugging users with
an error message – which we also switch to a warning as a failure to
open the file is "just" a warning, so the 'wrong' owner shouldn't be
that much of an issue.
The file is still handled with chmod, so all the security we can enforce
is still enforced of course, which also gets a warning if it fails.

First redirect output to a file, then redirect other outputs to this
output, not the other way around as this will not work.

The constructors of our (clear)sign-acquire-items move a pre-existent
file for error-recovery away, which gets restored or discarded later as
the acquire progresses, but --print-uris never really starts the
acquire process, so the files aren't restored (as they should).
To fix this both get a destructor which checks for signs of acquire
doing anything and if it hasn't the file is restored.
Note that these virtual destructors theoretically break the API, but
only with classes extending the sign-acquire-items and nobody does this,
as it would be insane for library users to fiddle with Acquire
internals – and these classes are internals.

For many commands the output isn't stable (like then dpkg is called) but
the exitcode is, so this helper enhances the common && msgpass ||
msgfail by generating automatically a msgtest and showing the output of
the command in case of failure instead of discarding it unconditionally,
the later being chronic-like behaviour

Signing files with expired keys is not as easy as it sounds, so the
framework jumps a few loops to do it, but it might come in handy to have
an expired key around for later tests even if it is not that different
from having no key in regards to APT behaviour.

The handwritten parsing here was mostly done as we couldn't trust the
Release file we got, but nowadays we are sure that the Release file is
valid and contains just a single section we want it to include.
Beside reducing code it also fixes a bug: Fieldnames in deb822 formatted
files are case-insensitive and pkgTagFile does it correctly, but this
selfbuilt stuff here didn't.
|
|
The file we read will always be a Release file as the clearsign is
stripped earlier in this method, so this check is just wasting CPU
Its also removing the risk that this could ever be part of a valid
section, even if I can't imagine how that should be valid.

We start your quest by using the version of a package applying to a
specific pin, but that version could very well be below the current
version, which causes APT to suggest a downgrade even if it is
advertised that it never does this below 1000.
Its of course questionable what use a specific pin on a package has
which has a newer version already installed, but reacting with the
suggestion of a downgrade is really not appropriated (even if its kinda
likely that this is actually the intend the user has – it could just as
well be an outdated pin) and as pinning is complicated enough we should
atleast do what is described in the manpage.
So we look out for the specific pin and if we haven't seen it at the
moment we see the installed version, we ignore the specific pin.

The rational from the buglog:
> The problem here is that the Priority field in one of the Packages files
> is incorrect due to a mishap with reprepro configuration, […] the
> amd64 version is Priority: standard but the arm64 version is Priority:
> optional (and has a stray "optional: interpreters" field).
> […]
> However, Priority is a rather weak property of a package because it's
> typically applied via overrides, and it's easy for maintainers of
> third-party repositories to misconfigure them so that overrides aren't
> applied correctly. It shouldn't be ranked ahead of choosing packages
> from the native architecture. In this case, I have no user-mode
> emulation for arm64 set up, so choosing m4:arm64 simply won't work.
This effectly makes the priority the least interesting data point in
chosing a provider, which is in line with the other checks we have
already order above priority in the past and also has a certain appeal by
the soft irony it provides.

nl_langinfo is used to acquire the YESEXPR of the language used,
but it will return the one from LC_MESSAGES, which might be different
from the language chosen for display of the question (based on LANGUAGE)
so this commit removes the [Y/n] help text from the questions itself and
moves it to the prompt creation in which the usage of LC_MESSAGES is
forced for it, so that the helptext shown actually represents the
characters accepted as input for the question.
There is still room for problems of course starting with an untranslated
"[Y/n]" but a translated YESEXPR or the problem that the question is
asked in a completely different language which might have a conflicting
definition of [Y/n] input or the user simple ignores the helptext and
assumes that an answer matching the question language is accepted, but
the mayority of users will never have this problem to begin with, so we
should be fine (or at least a bit finer than before).
Closes nothing really, but should at least help a bit with bugs like
deb:194614, deb:471102, lp:1205578, and countless others.

Lintian complains about these links in the source package as they leave
the source directory and as they are autogenerated there isn't that much
sense in shipping them, we can just recreate them before calling
configure.

It works for a while now in manual tests, now lets see how it will
perform if enabled for all by default automatically.
|

And while at it ensure that this can't happen again by letting the build
fail in case a po file is available but the language isn't mentioned in
the LINGUAS file (not even as a disabled language).

The list shows that it is ignored as some translations which are shipped
are not included here, so remove this source of possible confusion.

Using the static FileFd::Write method gives us error messages for free
so we use it here to avoid failing silently (with a fail silent error).

Commit 2b9c9b7f28b18f6ae3e422020e8934872b06c9f3 not only removes
keep-alive, but also changes the request URI send to proxies which are
required to be absolute URIs rather than the usual absolute paths.

On CD-ROMs Translation-* files are only in compressed form included in
the Release file. This used to work while we had no record of
Translation-* files in the Release file at all as APT would have just
guessed the (compressed) filename and accepted it (unchecked), but now
that it checks for the presents of entries and if it finds records it
expects the uncompressed to be verifiable.
This commit relaxes this requirement again to fix the regression.
We are still secure "enough" as we can validate the compressed file we have
downloaded, so we don't loose anything by not requiring a hashsum for
the uncompressed files to double-check them.
