We autocreate for a while now the last two directories in /var/lib/apt/lists
(similar for /var/cache/apt/archives) which is very nice for systems having
any of those on tmpfs or other non-persistent storage. This also means
though that this creation is effected by the default umask, so for
people with aggressive umasks like 027 the directories will be created
with 750, which means all non-root users are left out, which is usually
exactly what we want then this umask is set, but the cache and lib
directories contain public knowledge. There isn't any need to protect
them from viewers and they render apt completely useless if not
readable.

Usually they don't provide a lot in terms of what they test, but they
help in covering many lines from strictly anecdotal commands (stats,
moo) and error messages, so that stuff which really needs to be tested,
but isn't is better visible in coverage reports.

We create our own directories here and work without root in them, so we
can also test the locking with them as it is how we usually operate.

dpkg wants to know about a package before it can be put on hold, so we
have to at least hint about its existance in the available file it
"maintaince" to know about such stuff. The simple thing would probably
be to just feed all Packages files into dpkg as well, but what would be
the point really? Exactly, so we take a shortcut here and just create
dummies in the available file if we need to which isn't going to be that
common as usually you are holding packages back and not off.
Who would have thought that a simple feature like setting a package on
hold requires more than 200 lines of code… at least with the testcase it
is now explicitly tested code.

The tool checks for debconf version before printing the info it
extracts, so that it doesn't extract data which can't be interpreted
before debconf is upgraded. It is only fair to check for this behaviour
in the tests.

By convention, if I run a tool with --help or --version I expect it to
exit successfully with the usage, while if I do call it wrong (like
without any parameters) I expect the usage message shown with a non-zero
exit.

One word: "doh!" Commit f6d4ab9ad8a2cfe52737ab620dd252cf8ceec43d
disabled the check to prevent apt from downloading bigger patches
than the index it tries to patch. Happens rarly of course, but still.
Detected by scan-build complaining about a dead assignment.
To make up for the mistake a test is included as well.

Handle Translation-* files exactly like Packages files (with the
expection that it is ok if a download of them fails). Remove all
"guessing" on apts side. This will elimimnate a bunch of errors
releated to captive portals and similar. Its also more correct
and removes another potential attack vector.

It is a very simple hashstring, which is why it isn't contributing to
the usability of a list of them, but it is also trivial to check and
calculate, so it doesn't hurt checking it either as it can combined even
with the simplest other hashes greatly complicate attacks on them as you
suddenly need a same-size hash collision, which is usually a lot harder
to achieve.

It is sometimes handy to have an installed package also in the archive,
but this was until now harder than it should as you had to duplicate the
lines, which is especially dangerous while writing the tests as it
easily happens that these two lines divert and so the same-but-different
version detection kicks in.

We can use either and some tests exercise this, but the default should
be what we want to use and that is a split out long description file
which is properly mentioned in the Release file.

partial files are chowned by the Item baseclass to let the methods work
with them. Now, this baseclass is also responsible for chowning the
files back to root instead of having various deeper levels do this.
The consequence is that all overloaded Failed() methods now call the
Item::Failed base as their first step. The same is done for Done().
The effect is that even in partial files usually don't belong to
_apt anymore, helping sneakernets and reducing possibilities of a bad
method modifying files not belonging to them.
The change is supported by the framework not only supporting being run
as root, but with proper permission management, too, so that privilege
dropping can be tested with them.
|
|
Private temporary directories as created by e.g. libpam-tmpdir are nice,
but they are also very effective in preventing our priviledge dropping
to work as TMPDIR will be set to a directory only root has access to, so
working with it as _apt will fail. We circumvent this by extending our
check for a usable TMPDIR setting by checking access rights.

Adds a new testwarning which tests for zero exit and the presents of a
warning in the output, failing if either is not the case or if an error
is found, too. This allows us to change testsuccess to accept only
totally successful executions (= without warnings) which should help
finding regressions.

These functions check the exit code of the command, but for apt commands
we can go further and require an error message for non-zero exits and
none for zero exits.

Adds some infrastructure to run tests automatically for certain
commands. The first command being 'apt-get update' (and 'apt update')
which check for correct permission and owner of the files in lists/.

If we get an IMS hit for an InRelease file we use the file we already
have and pass it into reverification, but this changes the permissions
and on abort of the transaction they weren't switched back.
This is now done, additionally, every file in partial which hasn't
failed gets permission and owner changed for root access as well, as it
is very well possible that the next invocation will (re)use these files.
|
|
The conversion to accept only relevant options for commands has
forgotten another one, so adding it again even through the usecase might
very well be equally good served by --print-uris.

We do not support compressed indexes for cdrom sources as we rewrite
some of them, so supporting it correctly could be hard. What we do
instead in the meantime is probably disabling it for cdrom sources.

The acquire code changed completely, so this is more an import of the
testcase and a new fix than the merge of an existent fix.

Regression from merging 801745284905e7962aa77a9f37a6b4e7fcdc19d0 and
b0f4b486e6850c5f98520ccf19da71d0ed748ae4. While fine by itself, merged
the part fixing the filename is skipped if a cdrom source is
encountered, so that our list-cleanup removes what seems to be orphaned
files.

Running the testcases is usually not a good idea, but it can be handy to

Add a new configallowinsecurerepositories that controls the value
of Acquire::AllowInsecureRepositories for the tests. Set it to
"false" for most of the testsuite and only enable it where its
really needed. We want to switch the default for this post-jessie.

The constructor is calling the baseclass pkgAcqIndex which does this
already – and also does it correctly for compressed files which would
overwise lead to the size of uncompressed files to be expected.

Do not require a special flag to be present to update trusted=yes
sources as this flag in the sources.list is obviously special enough.
Note that this is just disabling the error message, the user will still
be warned about all the (possible) failures the repository generated, it
is just triggering the acceptance of the warnings on a source-by-source
level.
Similarily, the trusted=no flag doesn't require the user to pass
additional flags to update, if the repository looks fine in the view of
apt it will update just fine. The unauthenticated warnings will "just" be
presented then the data is used.
In case you wonder: Both was the behavior in previous versions, too.

The test generates failures if the created deb files have the same size,
so we try a little harder to avoid having the same size for them.

On travis-ci connect.cc detects a rotation, triggering it store the IP
which is later appended to the error message, which is all nice and
great if we deal with a real server, but in the testcases it just
triggers failures as strings do not match.

Some distributions (or repositories) do not have as much
"Ign-discipline" as I would like to, so that could be pretty distracting
for our users if enabled by default. It is handy for testcases though.

This option controls the maximum size of Release/Release.gpg/InRelease
files. The rational is that we do not know the size of these files in
advance and we want to protect against a denial of service attack
where someone sends us endless amounts of data until the disk is full
(we do know the size all other files (Packages/Sources/debs)).

consistently using Item::Failed in all specializec classes helps setting
up some information bits otherwise unset, so some errors had an empty
reason as an error. Ign is upgraded to display the error message we
ignored to further help in understanding what happens.

Using a different user for calling methods is intended to protect us
from methods running amok (via remotely exploited bugs) by limiting what
can be done by them. By using root:root for the final directories and
just have the files in partial writeable by the methods we enhance this
in sofar as a method can't modify already verified data in its parent
directory anymore.
As a side effect, this also clears most of the problems you could have
if the final directories are shared without user-sharing or if these
directories disappear as they are now again root owned and only the
partial directories contain _apt owned files (usually none if apt isn't
running) and the directory itself is autocreated with the right
permissions.

Reworks the API involved in creating and setting up the fetcher to be a
bit more pleasent to look at and work with as e.g. an empty string for
no lock isn't very nice. With the lock we can also stop creating all our
partial directories "just in case". This way we can also be a bit more
aggressive with the partial directory itself as with a lock, we know we
will gone need it.
