Even if we only configure a single architecture, install dpkg, so
dpkg can assert multi arch correctly. This also has the nice side
effect of making single architecture and multiple architecture
test cases more uniform.
This fixes a regression from f878d3a862128bc1385616751ae1d78246b1bd01
("test: Assert multi-arch in the chroot").

If we copied one of the existing status files, we might not have

Introduce a new -qq mode for our integration test framework,
and make travis use it.
The new -qq mode sets MSGLEVEL to 1. In MSGLEVEL=1, no messages
are generated for passed tests, and all testcase filenames are
printed in the same line.
Also install first in travis, do not ls the installed output
and run the install with chronic, so we only get output if it
failed.

Without randomizing the order in which we download the index files we
leak needlessly information to the mirrors of which architecture is
native or foreign on this system. More importantly, we leak the order in
which description translations will be used which in most cases will e.g.
have the native tongue first.
Note that the leak effect in practice is limited as apt detects if a file
it wants to download is already available in the latest version from a
previous download and does not query the server in such cases. Combined
with the fact that Translation files are usually updated infrequently
and not all at the same time, so a mirror can never be sure if it got asked
about all files the user wants.

On BSD systems, the root group is wheel, not root, so let's
just use the default group here.

The host system might not have a dpkg installed, which makes
dpkg fail with:
dpkg not recorded as installed, cannot check for multi-arch support!
That's entirely useless of course. We want to know if dpkg could
support multi-arch in our chroot, so we pseudo-install dpkg into
the chroot and pretend it's version is one version higher than
the minimum dpkg version, so dpkg --assert-multi-arch works on
recent dpkgs.

This check should work regardless if dpkg was installed by dpkg
or by a native package manager like RPM or pkg.

This is more safe against sticky bits. For example, in FreeBSD
all files created in /tmp have the group set to wheel.

This breaks the tests with FreeBSD's shell, and is not needed -

Use of echo with special characters is not portable. On a normal
POSIX system, the behavior with backslash escaped strings is
implementation-defined. On an XSI-conformant system, they must
be interpreted.
A way out is the printf command - printf "%b" specifies that
the following argument is to be printed with backslash escapes
interpreted.

Especially on non-Debian platforms, dpkg might not list itself
on the host system, and thus dpkg --assert-multi-arch fails.

Our test suite assumes that dpkg's admindir is var/lib/dpkg. This
might not always be true; for example, on FreeBSD, it is located
at /var/db/dpkg.

This allows other vendors to use different paths, or to build
your own APT in /opt for testing. Note that this uses + 1 in
some places, as the paths we receive are absolute, but we need
to strip of the initial /.

In most cases apt was already skipping the (re)setting of packages as
to be removed/purged if dpkg had told us that it already did, but we
haven't dealt with it in the most obvious of the cases: Selections set
for packages we touched in this operation which either restores
selections even dpkg would have overridden or e.g. tries to restore a
purge selection for a package which was just purged – does not happen
with apt itself as it isn't using selections in this way, but higher
frontends like aptitude do.
The result in the later case is a warning printed by dpkg that we try to
set selections for an unknown package, which is harmless per se, but can
be confusing for users and we really shouldn't cause warnings in dpkg if
we can help it.

The bugreport shows a segfault caused by the code not doing the correct
magical dance to remove an item from inside a queue in all cases. We
could try hard to fix this, but it is actually better and also easier to
perform these checks (which cause instant failure) earlier so that they
haven't entered queue(s) yet, which in return makes cleanup trivial.
The result is that we actually end up failing "too early" as if we
wouldn't be careful download errors would be logged before that process
was even started. Not a problem for the acquire system, but likely to
confuse users and programs alike if they see the download process
producing errors before apt was technically allowed to do an acquire
(it didn't, so no violation, but it looks like it to the untrained eye).

We need to support partial upgrades anyhow, so we have to deal with the
different versions and your tests try to ensure that we do, so we
shouldn't make any explicit higher requirements.

With cmake using BUILDDIRECTORY at this place is not only as wrong as it
was before, but it might not even work always copying the system
provided one which might or might not be current and hence fails tests
needing it to be current like ./test-apt-move-and-forget-manual-sections
We don't want to always use the one from the source directory through
either like in autopkgtests.

This early support seems a bit hacky, but it's a hard switch: The
integration tests do not understand the old build system anymore
afterwards. I don't really like that.

Hardcoding /var/crash means we can't test it properly and it isn't

The existing cleanup was happening only for packages which had a status
change (install -> uninstalled) which is the most frequent but no the
only case – you can e.g. set autobits explicitly with apt-mark.
This would leave stanzas in the states file declaring a package to be
manually installed – which is the default value for a package not listed
at all, so we can just as well drop it from the file.

Otherwise calls like "apt -q install" end up calling "aptautotest_apt_q"
instead of "aptautotest_apt_install"

Theoretically it should be enough to change the Dir setting and have apt
pick the dpkg/status file from that. Also, it should be consistently
effected by RootDir. Both wasn't really the case through, so a user had
to explicitly set it too (or ignore it and have or not have expected
sideeffects caused by it).
This commit tries to guess better the location of the dpkg/status file
by setting dir::state::status to a naive "../dpkg/status", just that
this setting would be interpreted as relative to the CWD and not
relative to the dir::state directory. Also, the status file isn't really
relative to the state files apt has in /var/lib/apt/ as evident if we
consider that apt/ could be a symlink to someplace else and "../dpkg"
not effected by it, so what we do here is an explicit replace on apt/
– similar to how we create directories if it ends in apt/ – with dpkg/.
As this is a change it has the potential to cause regressions in so far
as the dpkg/status file of the "host" system is no longer used if you
set a "chroot" system via the Dir setting – but that tends to be
intended and causes people to painfully figure out that they had to set
this explicitly before, so that it now works more in terms of how the
other Dir settings work (aka "as expected"). If using the host status
file is really intended it is in fact easier to set this explicitely
compared to setting the new "magic" location explicitely.

Most tests are either multiarch, do not care for the specific
architecture or do not interact with dpkg, so really effect by this is
only test-external-installation-planner-protocol, but its a general
issue that while APT can be told to treat any architecture as native
dpkg has the native architecture hardcoded so if we run tests we must
make sure that dpkg knows about the architecture we will treat as
"native" in apt as otherwise dpkg will refuse to install packages from
such an architecture.
This reverts f883d2c3675eae2700e4cd1532c1a236cae69a4e as it complicates
the test slightly for no practical gain after the generic fix.

The setup didn't prepare the directories as expected by newer version of
tthe external tests in an autopkgtests environment.

If we have files in partial/ from a previous invocation or similar such
those could be symlinks created by file:// sources. The code is
expecting only real files through and happily changes owner,
modification times and permission on the file the symlink points to
which tend to be files we have no business in touching in this way.
Permissions of symlinks shouldn't be changed, changing owner is usually
pointless to, but just to be sure we pick the easy way out and use
lchown, check for symlinks before chmod/utimes.

It can be handy to set apt options for the testcases which shouldn't be
accidentally committed like external planner testing or workarounds for
local setups.

All apt versions support numeric as well as 3-character timezones just
fine and its actually hard to write code which doesn't "accidently"
accepts it. So why change? Documenting the Date/Valid-Until fields in
the Release file is easy to do in terms of referencing the
datetime format used e.g. in the Debian changelogs (policy §4.4). This
format specifies only the numeric timezones through, not the nowadays
obsolete 3-character ones, so in the interest of least surprise we should
use the same format even through it carries a small risk of regression
in other clients (which encounter repositories created with
apt-ftparchive).
In case it is really regressing in practice, the hidden option
-o APT::FTPArchive::Release::NumericTimezone=0
can be used to go back to good old UTC as timezone.
The EDSP and EIPP protocols use this 'new' format, the text interface
used to communicate with the acquire methods does not for compatibility
reasons even if none of our methods would be effected and I doubt any
other would (in these instances the timezone is 'GMT' as that is what
HTTP/1.1 requires). Note that this is only true for apt talking to
methods, (libapt-based) methods talking to apt will respond with the
'new' format. It is therefore strongly adviced to support both also in
method input.

apt-key needs gnupg for most of its operations, but depending on it
isn't very efficient as apt-key is hardly used by users – and scripts
shouldn't use it to begin with as it is just a silly wrapper. To draw
more attention on the fact that e.g. 'apt-key add' should not be used in
favor of "just" dropping a keyring file into the trusted.gpg.d
directory this commit implements the display of warnings.

Julian noticed on IRC that I fall victim to a lovely false friend by
calling referring to a 'planer' all the time even through these are
machines to e.g. remove splinters from woodwork ("make stuff plane").
The term I meant is written in german in this way (= with a single n)
but in english there are two, aka: 'planner'.
As that is unreleased code switching all instances without any
transitional provisions. Also the reason why its skipped in changelog.

In 385d9f2f23057bc5808b5e013e77ba16d1c94da4 I implemented the storage of
scenario files based on enabling this by default for EIPP, but I
implemented it first optionally for EDSP to have it independent.
The reasons mentioned in the earlier commit (debugging and bugreports)
obviously apply here, especially as EIPP solutions aren't user approved,
nearly impossible to verify before starting the execution and at the
time of error the scenario has changed already, so that reproducing the
issue becomes hard(er).
|
|
Testing the current implementation can benefit from being able to be
feed an EIPP request and produce a fully compliant response. It is also
a great test for EIPP in general.
|

The very first step in introducing the "external installation planer
protocol" (short: EIPP) as part of my GSoC2016 project.
The description reads: APT-based tools like apt-get, aptitude, synaptic,
… work with the user to figure out how their system should look like
after they are done installing/removing packages and their dependencies.
The actual installation/removal of packages is done by dpkg with the
constrain that dependencies must be fulfilled at any point in time (e.g.
to run maintainer scripts).
Historically APT has a super micro-management approach to this task
which hasn't aged that well over the years mostly ignoring changes in
dpkg and growing into an unmaintainable mess hardly anyone can debug and
everyone fears to touch – especially as more and more requirements are
tacked onto it like handling cycles and triggers, dealing with
"important" packages first, package sources on removable media, touch
minimal groups to be able to interrupt the process if needed (e.g.
unattended-upgrades) which not only sky-rocket complexity but also can
be mutually exclusive as you e.g. can't have minimal groups and minimal
trigger executions at the same time.

This effects only compressors configured on the fly (rather then the
inbuilt ones as they use a library).
|
|
Most (if not all) solvers should be able to run perfectly fine without
root privileges as they get the entire state they are supposed to work
on via stdin and do not perform any action directly, but just pass
suggestions on via stdout.
The new default is to run them all as _apt hence, but each solver can
configure another user if it chooses/must. The security benefits are
minimal at best, but it helps preventing silly mistakes (see
35f3ed061f10a25a3fb28bc988fddbb976344c4d) and that is always good.
Note that our 'apt' and 'dump' solver already dropped privileges if they
had them.

gpg doesn't give use a UID on NODATA, which we were "expecting" (but not
using for anything), but just an error number. Instead of collecting
these as badsigners which will trigger a "invald signature" error with
remarks like "NODATA 1" we instead adapt a message similar to the NODATA
error of a clearsigned file (which is actually not reached anymore as we
split them up, which fails with a NOSPLIT error, which uses the same
general error message).
In other words: Not a security relevant change, just a user experience
improvement as we now point them to the most likely cause of the
problem instead of saying "invalid signature" which would point them in
the direction of the archive being broken (for everyone) instead.

Most tests just need a signed repository and don't care if it signed by
an InRelease file or a Release.gpg file, so we can save some time by
just generating one of them by default.
Sounds like not much, but quickly adds up to a few seconds with the
amount of tests we have accumulated by now.

If the test just signs release files to throw away one of them to test

Daniel Kahn Gillmor highlights in the bugreport that security isn't
improving by having the user import additional keys – especially as
importing keys securely is hard.
The bugreport was initially about dropping the warning to a notice, but
in given the previously mentioned observation and the fact that we
weren't printing a warning (or a notice) for expired or revoked keys
providing a signature we drop it completely as the code to display a
message if this was the only key is in another path – and is considered
critical.
Closes: 618445
|
|
Signatures on data can have an expiration date, too, which we hadn't
handled previously explicitly (no problem – gpg still has a non-zero
exit code so apt notices the invalid signature) so the error message
wasn't as helpful as it could be (aka mentioning the key signing it).
|
|
Users tend to report these errors with just this error message… not very
actionable and hard to figure out if this is a temporary or 'permanent'
mirror-sync issue or even the occasional apt bug.
Showing the involved hashsums and modification times should help in
triaging these kind of bugs – and eventually we will have less of them
via by-hash.
The subheaders aren't marked for translation for now as they are
technical glibberish and probably easier to deal with if not translated.
After all, our iconic "Hash Sum mismatch" is translated at least.
These additions were proposed in #817240 by Peter Palfrader.
