We added weak signatures to BadSigners, meaning that a Release file
signed by both a weak signature and a strong signature would be
rejected; preventing people from migrating from DSA to RSA keys
in a sane way.
Instead of using BadSigners, treat weak signatures like expired
keys: They are no good signatures, and they are worthless.

This keeps a list of weak digest algorithms. For now, only MD5
is disabled, as SHA1 breaks to many repos.

This reverts commit 76a71a1237d22c1990efbc19ce0e02aacf572576.
That commit broke the test suite.

ERRSIG is created whenever a key uses an unknown/weak digest
algorithm, for example. This allows us to report a more useful
error than just "unknown apt-key error.":
The following signatures were invalid: ERRSIG 13B00F1FD2C19886 1 2 01 1457609403 5
While still not being the best reportable error message, it's
better than unknown apt-key error and hopefully redirects users
to complain to their repository owners.

This was wrong and caused some issues because apt-key invoked
host apt-config with our library.

This makes the test suite safe if we ever need to reject SHA1
signatures in an update.

"%s can not be marked as it is not installed." was incorrectly
translated as "%s no se puede marcar como no instalado.\n",
which means "%s can not be marked as not installed."
Thanks to Marcos Del Sol Vives for reporting & to the spanish
translation team – and in particular Camaleón and Venturi –
for review and correction of this issue!

The structure we parse the data into has a dedicated size field, but it
tends to be easier to handle it as a (very weak) checksum.
|
|
The URI descibing an item can change via mirrors/redirectors which
causes the .diff/Index files to get the wrong names in storage.

The (unlikely) waitpid failure case should fallthrough the code just
like the other failures (and successes) instead of taking a shortcut
avoiding all the cleanup (progress) and finishing touches (log, state).
This also delays the cleanup of the progress until apt is really done
with everything and "just" has the post-invokes left to do, so the
period of 'apt looks finished as it stopped the progress' and 'apt
really finished as I have the shell-prompt back' is shorter even if
there is no progress reported anymore, so the bar lingers at 100%…
Ideally even the post-invokes would be covered by progress, but they
can have their own output and dealing with that could be hard.

All other interactions with std::cout are flushed directly, just in the
stop case we hadn't done it – no problem expect if there is still output
coming after apt is done like in the case of a post-invoke script
producing output.

Iceweasel^WFirefox complains about the missing encoding in its console
which can be a bit annoying in interactive sessions, so fixing these
issues has no effect on apt itself, but on the testers.

Now that we ignore SHA1-only files it makes sense to require also the
provision of hashes for the compressed patches as this was introduced in
the same patchset as support for non-SHA1 hashes in the file itself in
dak and adding support in other archive creators (if they support pdiffs
at all) will likely be in the same batch.
The reason for the change itself is simple: If you are 'scared' enough
about the security of SHA1, you shouldn't uncompress a file you haven't
verified at all – after all, it could be exploiting a bug or a zip bomb.
|
|
Given that we refuse to use SHA1-only .diff/Indexes no point in shipping
and running code which pretends to check support for it which given that
all these tests are run 3 times eats a noticeable amount of time.
Git-Dch: Ignore
|
|
Ensure that .diff/Index files that only contain SHA1 values and no
SHA2 values are not used.
|
|
SHA1 is not reasonably secure anymore, so we should not consider it
usable anymore. The test suite is adjusted to account for this.

Using amd64 broke the test case on non-amd64 architectures. Query
the native architecture from dpkg and use that instead.
The definition of NATIVE is copied from the test

We do not follow the recommendation with regards to placement
of documentation in apt-doc, as we install in apt-doc, but
it's only a recommendation and I don't want think we should
move them.

Mysteriously segfaults only on i386 for me, but at least one reporter
had the same behavior and it makes sense that this is the problem as the
parsing of Source: was fixed in 1.2.2 – before the not remapped group
was not used.
We don't use our usual Dynamic<> trick here as we don't have it in the
parser. Its a bit of a layer violation to do this parsing here, but its
how it is always was…
Until next time with this lovely kind of problem.
Closes: 812251
Thanks: Francesco Poli and Marc Haber for testdata.

If an iterator or a stringview has multiple dynamic objects
registered with it, it may be remapped twice. Prevent that
by noting which iterators/views we have seen and not remapping
one if we have already seen it.
We most likely do not have any instance of multiple dynamics
on a single object, but let's play safe - the overhead is not
high.

If a single pdiff fails, we have to fail the entire patching endeavour
and fall back to getting the complete file instead. That is easy in
serverside merged pdiffs as we get them one by one. For clientside we
get them all at once through, which means that a failure in one has to
stop the entire pipeline, which works as expected (as proven by the
bugreporters as they don't even notice it happening). The problem is
just that the first failing pdiff will do the cleanup, so another pdiff
which happens to be successfully acquired after we processed the failure
doesn't find the file it is supposed to use as a basename anymore, so
the patch is renamed to what should be the unique extension and moved
into the current working directory. Processing is then stopped as the
patch realizes that it isn't the last one which completed downloading.
On the plus side this means this is neither us using a bad temporary
location nor a security problem. It "just" overrides unconditionally
files in your current working directory (if you happen to have them
named like a pdiff patch – a bit unlikely perhaps) and so drops files
there which are never used again.
I guess this was introduced in 4e3c5633b1e74b4f58b95f339cfbbf4cbf21ab3e
for real as I made the need for the existence of the base file rather
explicit, but the potential lingers in the code for far longer.

The liblzma-based write code needs the same tweaks that the read code
already has to cope with the situation where lzma_code returns zero the
first time through because avail_out is zero, but will do more work if
called again.
This ports the read tweaks to the write code as closely as possible
(including matching comments etc.).
Closes: #751688

Fixed in f7bd44bae0d7cb7f9838490b5eece075da83899e already, but the
commit misses the Closes tag and while we are at it we can add a simple
regression test and micro-optimize it a bit.
Thanks: James McCoy for the suggestion.

In a249b3e6fd798935a02b769149c9791a6fa6ef16 I dropped with the manual
first resolver step also the support for installing build-deps as
automatic in such a way that it behaved like this option was enabled by
default.
Restoring support for it means that we go back to mark build-
dependencies as manually installed again by default and provide this
option to keep them as automatically installed.
|

This way we hopefully notice (new) warnings in this little helper.

Changelogs are relatively small and we have no hashes for them, but we
had partial support for them before, so lets stick to it.
This also deletes the (partial) file before moving the downloaded file
into its place – rename(2) should be doing this by itself, but testing
on semaphoreci suggests that this isn't always the case (error is "Stale
file handle") and we don't need an atomic replace here, so be explicit.

pkgAcqChangelog has the default behaviour of downloading a changelog to
a temporary directory (inside /tmp, not /tmp directly), which is cleaned
up on shutdown, but this can be overridden to store the changelog more
permanently – but that caries a permission problem.
For changelog we can 'easily' solve this by always downloading to a
temporary directory and only move it out of there on done.
|
|
If pkgAcqChangelog is told to acquire the changelog for a version it
will check first if this version is installed on the disk and if so will
use the local changelog in /usr/share/doc (possibily/likely gz
compressed) instead of downloading the file from the web.
An option is provided to disable this, which is enabled by default for
the Ubuntu vendor as they truncate the local changelogs – and for apts
--print-uris action.
|

Build system messed up the 1.2.2 commit by not updating the
.po files properly, so they are now.
|
|
Otherwise the test run as root fails seeing the
W: Can't drop privileges for downloading as file 'foo_1.tar.gz' couldn't be
accessed by user '_apt'. - pkgAcquire::Run (13: Permission denied)
warning in a command which isn't supposed to warn.
One trivial test, two fixups and still counting…

Travis still uses a dpkg version which defaults to gz and as which

Regression introduced in a249b3e6fd798935a02b769149c9791a6fa6ef16, which
in the case of an invalid cache would build the first part unlocked and
later pick up the (still unlocked) cache for further processing, so the
system got never locked and apt would end up complaining about being
unable to release the lock at shutdown.
The far more common case of having a valid cache worked as expected and
hence covered up the problem – especially as tests who would have
noticed it are simulations only, which do not lock.

If we just reopened the file, we also need to reset the current
seek position when we reset the buffer, otherwise the code will
not try to seek to the position given to Skip (from 0), but will
try to seek to old offset + the position given to skip.
Closes: #812994, #813000

When writing into the buffer write to free() bytes starting
at getend(), instead of buffersize_max bytes at get()
-> get() is a read pointer.
This makes no difference in practice though, as we reset
the buffer before the call, so start = end = 0.
