An SRV record includes a portnumber to use with the host given, but apt
was ignoring the portnumber and instead used either the port given by
the user for the initial host or the default port for the service.
In practice the service usually runs on another host on the default
port, so it tends to work as intended and even if not and apt can't get
a connection there it will gracefully fallback to contacting the initial
host with the right port, so its a user invisible bug most of the time.

The apt-transport-tor package operates via simple symlinks which can
result in 'http' being called as 'tor+https', so it must pick up the
right configuration pieces and trigger https support also in plus names.

This should fix some issues with dpkg normalizing such
values. Suprisingly enough apt treats the Version: field
the same, even with epoch vs without, but not when searching,
and does not strip the 0: from the output.
|
|

|
If we have a user sitting around we can let 'apt' ask the user for a
confirmation rather than print errors at the end and require the user to
figure out which commandline flags are needed to confirm the changes
non-interactively.
|
|
Having messages being printed on the error stack and confirm them by
commandline flags is an okayish first step, but some frontends will
probably want to have a more interactive feeling here with a proper
question the user can just press yes/no for as for some frontends a
commandline flag makes no sense…

This gives the repository owner a chance to explain why this change was
needed – e.g. explaining the organisational changes or simply detailing
the changes in the new release made. Note that this URI is also shown
if the change is accepted, so it also draws attention to release notes
of minor updates (if users watch apt output closely).
|
|
The value of Origin, Label, Codename and co can be used in user
configuration from apts own pinning to unattended upgrades.
A repository changing this values can therefore have serious effects on
the behaviour of apt and other tools using these values.
In a first step we will generate error messages for these changes now
explaining the need for explicit confirmation and provide config options
and commandline flags to accept them.
|

The exception was made to give (script) users a one-release grace period
to adapt their setup to deal with apt enforcing signing of repositories.
As we are now at the start of a new release cycle its as good a time as
any to lift it now.

As requested by Henrique de Moraes Holschuh, here comes
an option to disable TLS support. If the option is set
to false, the internal TLS layer is disabled.

The http method will eventually replace the curl-based
https method, but for now, this is an opt-in experiment
that can be enabled by setting Dir::Bin::Methods::https
to "http".
Known issues:
- We do not support HTTPS proxies yet
- We do not support proxying HTTPS connections yet (CONNECT)
- IssuerCert and SslForceVersion are unsupported

Use std::unique_ptr<MethodFd> everywhere we used an
integer-based file descriptor before. This allows us
to implement stuff like TLS support easily.
Gbp-Dch: ignore

This will allow us to access ConfigFind() and stuff which makes
it possible for us to implement TLS support.

On Travis CI running tests with code coverage enabled sometimes
generates profiling lines, which we filter out for a while now,
but that misses lines generated showing progress still causing test
failures, so more sed logic is added in the hopes to ignore them.

The error cases are just as unlikely as the memory leaks to ever cause
real problems, but lets play it safe for correctness.

An unknown code should be handled the same as the x00 code of this
group, but for redirections we used to treat 300 (and a few others)
as an error while unknown codes were considered redirections.
Instead we check now explicitly for the redirection codes we support for
redirecting (and add the 308 defined in RFC 7538) to avoid future
problems if new 3xx codes are added expecting certain behaviours.
Potentially strange would have been e.g. "305 Use Proxy" sending a
Location for the proxy to use – which wouldn't have worked and resulted
in an error anyhow, but probably confused users in the process.

There are very many HTTP errorcodes which indicate that the repository
isn't available at the moment or the connection has some kind of
problem. Given that we do not require Release files the result was that
these errors were ignored and the user presented with a message like
"Repository is no longer signed" which sends the user in the wrong
direction.
Instead of trying to figure out which http errorcodes indicate a global
problem we accept only 404 for ignoring and consider all the rest as
hard errors now causing us to stop instantly after the InRelease file
and print the errorcode (with short description from server) received.

Moving the code responsible for parsing the Index file from ::Done into
the slightly earlier ::VerifyDone allows us to still "fail" the download
if we can't make use of the Index for whatever reason, so that the
progress log correctly displays "Ign" instead of "Get" for the file.
This also makes quiet a few debug messages proper error messages (but
those are still hidden by default for Ign lines).

If we couldn't find an entry for a Sources file we would generate an
error while for a Packages file we would silently skip it due to
assuming it is missing because it is empty. We can do better by checking
if the repository declares that it supports a component we want to get
the file from and if not say so and hint at the user making a typo.
An example were this helps is mozilla.debian.net which dropped the
firefox-aurora component (as upstream did) meaning no upgrades until the
user notices manually that the repository doesn't provide packages
anymore. With this commit warnings are raised hopefully causing the user
to investigate what is wrong (sooner).

Adopting this change in other frontends will require source changes as
well similar to our own changes in apt-private/.

POSIX.1-2008 gives us a range of *at calls to deal with files
including the unlinkat so we can remove a file from a directory
based on a path to the file relative to the directory.
(In our case here the path we have is just the filename)
We avoid changing directories in this way which e.g. fails if the
directory we started in no longer exists or is otherwise inaccessible.

As the proxy commands are not executed as root, a user can run into
permission errors (s)he isn't expecting – as our switching is an
implementation detail – so the error message in that case should really
be better than a generic "error code 100" sending the user in the wrong
direction as that implies the command was executed, but errored out.

We setup a "horrible" environment in the apt-key testcase to check all
kinds of things, but we really should be making also at least a simple
apt update call, as that in turn will call apt-key which is how apt-key
is used in the non-testcase world, so that calling should be able to
deal with such environments as well.

Showing messages related to downloading in a mode which can't download
is pretty pointless, so instead of trying harder to make it so that
these messages do not trigger just skip them entirely.
That the message triggered here is an artifact of the implementation in
which the download items are finished, while the code expects them to be
still pending – even the in a previous run completely downloaded files.

Changes nothing on the program front and as the datatypes are
sufficently comparable fixes no bug either, but problems later on if we
ever change the types of those and prevent us using types which are too
large for the values we want to store waste (a tiny bit of) resources.

In complex situations in which we want to unpack a package which has a
conflict/breaks on another package which must be removed due this
conflict apt can decide to perform this remove earlier than initially
planned.
Problem: For three years apt wouldn't remove that package, but the
package which has the conflict… The situation isn't very common and
easily hidden as the package which is removed is unpacked a few actions
later – it becomes visible for packages which protect themselves from
removal through like systemd as the running init resulting in upgrade
failures (#854041).
Note that the package isn't purged, so data shouldn't be lost even if a
user runs into a "hidden" case of it as long as the package sticks to
the policy of removing data only on purge.
Reaching this situation artificially is hard, which is why no testcase
is included, as the situation is highly state dependent. Testing with
"real" systems indicate that slight modifications in the installed
packages set can make the bug not trigger.

We need to be able to update 1.4.y in different ways than later
apt versions, and thus need to bump the major version so there
is no collision in the minor version at some point.

Using dry-run as in the previous commit is not really correct, as
it logs dpkg debugging output too. So, let's assume unattended-upgrade
gets a --download-only option and use that if it is available.
This lets us add the downloading part to unattended-upgrades later
on, without requiring versioned dependencies between the two.

If the last alternative(s) of an Or group is ignored, because it does
not match an architecture list, we would end up keeping the or flag,
effectively making the next AND an OR.
For example, when parsing (on amd64):
debhelper (>= 9), libnacl-dev [amd64] | libnacl-dev [i386]
=> debhelper (>= 9), libnacl-dev |
Which can cause python-apt to crash.
Even worse:
debhelper (>= 9), libnacl-dev [amd64] | libnacl-dev [i386], foobar
=> debhelper (>= 9), libnacl-dev [amd64] | foobar
By setting the previous alternatives Or flag to the current Or flag
if the current alternative is ignored, we solve the issue.
