First of all, instead of creating the files at configure time,
generate the files using normal target. This has the huge advantage
that they are rebuilt if their input changes. While we are at it,
also add dependencies on the vendor entity files.
This also fixes the path to the vendor script, which was given
relatively before, which obviously won't work when running from
inside a deeper subdirectory.
To speed things up, pass the --vendor option to getinfo, so we
do not have to find out the current vendor in getinfo all over
again.

Cache the current vendor, so we do not have to rerun getinfo when
reconfiguring stuff. This also has the nice effect of making the
vendor configurable, so you can manually specify it on a platform
that might not have dpkg (not that building without dpkg works
yet).

This can be used to query a field for a specific vendor. It
also speeds up things a lot if we can cache the current vendor
in cmake and pass it to further getinfo invocations.

This new packaging is much easier to read, although the duplication
in the install files is a bit annoying. We should probably also get
rid of the movefiles for solvers, planners, and https method; but
then we have to keep track of which methods exist in the apt package.
Another disadvantage is that building only the documentation packages
also requires building the code, as there's no way to turn off code
building in the project.
|
|
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.

Build HTML docbook guides (untranslated) and manual pages
(including translations). Also install the examples in the
example subdirectory.
Translation of docbook guides has not been implemented yet,
but should be easy to do. The code also needs some cleanup
to automatically detect the available translations.
|
|
Introduce support for building translation domain-specific
templates, merging them with the translations, and building
a language-specific .mo file.
The invocation of xgettext is done in the project source
directory, not in the current source directory, and all paths
are made relative to the project root, in order to have clean
templates.
This only supports the C++ source code for now, it unfortunately
does not handle the shell scripts of deselect yet.
|
|
Introduce an initial CMake buildsystem. This build system can build
a fully working apt system without translation or documentation.
The FindBerkelyDB module is from kdelibs, with some small adjustements
to also look in db5 directories.
Initial work on this CMake build system started in 2009, and was
resumed in August 2016.

With this change, the 'library' command looks for a library libX
in the directories: build/bin, */X, X.
This allows it to find the library when building with the
upcoming CMake backend, which places the libraries in a sub
directory of the build tree with the same name as the source
tree.
For example, if building in 'build/', the apt-pkg library
will be available at 'build/apt-pkg/libapt-pkg.so.5.0'.
In case there are multiple instances of a library,
the newest one will be used.

This simplifies the design a bit, as we do not need to read the
major ABI version number from some file / command.

This makes it easier to write a generic subsitution tool for

Introduce the 'current' command to eventually replace the current
symbolic link. The current command does roughly the same as the
makefile, the code has just been cleaned up a bit to work better
as a shell function.

Commit b559d4846018c3adac362c6f1d0d697956586208 updated the
documentation to refer to apt.systemd.daily instead of the
apt cron job, introducing fuzzy strings in all the translations.

This fixes a test failures in the cmake branch which contains

AC_CHECK_FUNCS() defines HAVE_* variables, but AC_CHECK_FUNC()
does not.
Anyway: We do not have any code using HAVE_PTSNAME_R, so
just remove it.

This was disabled in 1999 by jgg due to "glibc bugs". Let's hope
those are fixed now, 17 years later.

While autotools defines all macros to 1 explicitly, CMake only
defines them without a value. In such a case, #if fails with an
error and #ifdef works.
In preparation for a possible switch to CMake and to clean up
the code (rest uses #ifdef), use #ifdef here

Previously, when data could be created and sig not, we would unlink
sig, not data (and vice versa).

gpgconf wasn't always equipped with a --kill option as highlighted by
our testcases failing on Travis and co as these use a much older version
of gpg2. As this is just for cleaning up slightly faster we ignore any
error a call might produce and carry on. Use a recent enough gpg2
version if you need the immediate killing…

apt-key has (usually) no secret key material so it doesn't really need
the agent at all, but newer gpgs insist on starting it anyhow. The
agents die off rather quickly after the underlying home-directory is
cleaned up, but that is still not fast enough for tools like sbuild
which want to unmount but can't as the agent is still hanging onto a
non-existent homedir.

Followup of b58e2c7c56b1416a343e81f9f80cb1f02c128e25.
Still a regression of sorts of 8b79c94af7f7cf2e5e5342294bc6e5a908cacabf.

If a solver/planner exits before apt is done writing we will generate
write errors. Solvers like 'dump' can be pretty quick in failing but
produce a valid EDSP error report apt should read, parse and display
instead of just discarding even through we had write errors.
|
|
There is no point in trying to perform Write/Read on a FileFd which
already failed as they aren't going to work as expected, so we should
make sure that they fail early on and hard.

Simulations are frequently run by unprivileged users which naturally
don't have the permissions to write to the default location for the eipp
file. Either way is bad as running in simulation mode doesn't mean we
don't want to run the logging (as EIPP runs the same regardless of
simulation or 'real' run), but showing the warnings is relatively
pointless in the default setup, so, in case we would produce errors and
perform a simulation we will discard the warnings and carry on.
Running apt with an external planner wouldn't have generated these
messages btw.

If another file in the transaction fails and hence dooms the transaction
we can end in a situation in which a -patched file (= rred writes the
result of the patching to it) remains in the partial/ directory.
The next apt call will perform the rred patching again and write its
result again to the -patched file, but instead of starting with an empty
file as intended it will override the content previously in the file
which has the same result if the new content happens to be longer than
the old content, but if it isn't parts of the old content remain in the
file which will pass verification as the new content written to it
matches the hashes and if the entire transaction passes the file will be
moved the lists/ directory where it might or might not trigger errors
depending on if the old content which remained forms a valid file
together with the new content.
This has no real security implications as no untrusted data is involved:
The old content consists of a base file which passed verification and a
bunch of patches which all passed multiple verifications as well, so the
old content isn't controllable by an attacker and the new one isn't
either (as the new content alone passes verification). So the best an
attacker can do is letting the user run into the same issue as in the
report.

The rewrite in 742f67eaede80d2f9b3631d8697ebd63b8f95427 is based on the
assumption that the pipeline will always be at least one item short each
time it is called, but the logs in #832113 suggest that this isn't
always the case. I fail to see how at the moment, but the old
implementation had this behavior, so restoring it can't really hurt, can
it?
|
|
Also fixes message itself to mention the correct option name as noticed
in #832113.

We read the entire input file we want to patch anyhow, so we can also
calculate the hash for that file and compare it with what he had
expected it to be.
Note that this isn't really a security improvement as a) the file we
patch is trusted & b) if the input is incorrect, the result will hardly be
matching, so this is just for failing slightly earlier with a more
relevant error message (althrough, in terms of rred its ignored and
complete download attempt instead).
|
|
The flush call is a no-op in most FileFd implementations so this isn't
as critical as it might sound as the only non-trivial implementation is
in the buffered writer, which tends not be used to buffer another
buffer…

APT doesn't know which packages will be triggered in the course of
actions, so it can't plan to see them for progress beforehand, but if it
sees that dpkg says that a package was triggered we can add additional
states. This is pretty much magic – after all it sets back the progress
– and there are cornercases in which this will result in incorrect
totals (package in partial states may or may not loose trigger states),
but the worst which can happen is that the progress is slightly
incorrect and doesn't reach 100%, but so be it. Better than being stuck
at 100% for a while as apt isn't realizing that a bunch of triggers
still need to be processed.
|
|
Hardcoding /var/crash means we can't test it properly and it isn't
really our style.
|
|
The progress reporting for a package sheduled for purging only included
the states dpkg passes through while actually purging the package – if
the package was fully installed before dpkg will pass first through all
remove states before purging it, so in the interest of consistent
reporting our progress reporting should do that, too.

If the sources file we want to edit doesn't exist yet GetLock will
create it with 640, which for a generic lockfile might be okay, but as
this is a sources file more relaxed permissions are in order – and
actually required as it wont be readable for unprivileged users causing
warnings/errors in apt calls.

After editing the sources it is a good idea to (re)built the caches as
they will be out-of-date and doing so helps in reporting higherlevel
errors like duplicates sources.list entries, too, instead of just
general parsing errors as before.
|
|
Closes: 832039
|
|
The tests changes the sources.list and the modification time of this
file is considered while figuring out if the cache can be good. Usually
this isn't an issue, but in that case we have the cache generation
produce warnings which appear twice in this case.

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.
