If a planner lets actions to be figured out by dpkg in pending calls
these actions aren't mentioned in a simulation. While that might be
a good thing for debugging, it would be a change in behavior and
especially if a planner avoids explicit removals could be confusing for
users. As such we perform the same 'trick' as in the dpkg implementation
by performing explicitly what would be done by the pending calls.
To save us some work and avoid desyncs we perform a layer violation by
using deb/ code in the generic simulation – and further we perform ugly
dynamic_cast to avoid breaking the ABI for nothing; aptitude is the only
other user of the simulation class according to codesearch.d.n and for
that our little trick works. It just isn't working if you happen to
extend pkgSimulate or otherwise manage to call the protected Go methods
directly – which isn't very realistic/practical.

The user has to approve the removal of a crossgraded package as it might
be needed to remove it (temporarily) in the process, but in most cases
we can happily avoid it and let dpkg unpack over it skipping the
remove. This has some effects on progress reporting and how deal with
selections through which makes this a tiny bit complicated.
|
|
Same reason and implementation as for configure.
|
|
A planner might not explicitly configure all packages, but we need to
know all packages which will be configured for progress reporting and to
tell the hook scripts about them as they rely on this for their own
functionality.
|
|
If we want a package to be purged from the system tell dpkg in the
ordering (if it has to touch it explicitly) to remove it and cover the
purging of the config files at the end with a --purge --pending call.
That should help packages move conffiles around between packages
correctly even if the user is purging packages directly in big actions
like dist-upgrades involving many packages.
|
|
Implemented a long while ago now with relatively good progress reporting
involving triggers is a good time to try delaying the execution of
triggers across dpkg invocations finally by default.
Note: The bugreport talks also about 'smarter' configuration which is a
much bigger part and approached from multiple directions, but doesn't
really involve triggers per-se so considering it decoupled should help
in getting it done…
Closes: #626599

Telling dpkg early on that we are going to remove these packages later
helps it with auto-deconfiguration decisions and its another area where
a planner can ignore the nitty gritty details and let dpkg decide the
course of action if there are no special requirements.
|
|
dpkg decides certain things on its own based on selections and
especially if we want to call --pending on purge/remove actions, we need
to ensure a clean slate or otherwise we surprise the user by removing
packages we weren't allowed to remove by the user in this run (the
selection might be an overarching plan for the not-yet "future").
Ideally dpkg would have some kind of temporal selection interface for
this case, but it hasn't, so we make it temporal with the risk of
loosing state if we don't manage to restore them.
|
|
Having long commandlines split into two is a huge problem if it happens
and additionally if we want to introduce planners which perform less
micromanagment its a good idea to leave the details for dpkg to decide.
In practice this doesn't work yet unconditionally as a bug is hiding in
the ordering code of dpkg, but it works if apt imposes its ordering so
this commit allows for now at least to solve the first problem.
|
|
APT (usually) knows which package is essential or not, so we can avoid
passing this force flag to dpkg unconditionally if the user hasn't
chosen a non-default essential handling obscuring the information.

This breaks -j and does all sort of other weird stuff I did not
notice in the previous (non-parallel) runs.

Look at the project root, and all directories directly below it and
pick the directory with the newest CMakeCache.txt file.

We cannot be sure if you are not running the build tree, so this

This causes build failures when turning translations off.

Teach the prepare-release script about the version new locations
and also set the version in CMakeLists, as that is better than
reading it from the changelog: CMake would not rerun automatically
otherwise if the version changed.

This can now build all documentation. It should also be fairly
reusable for other projects, as long as they follow the same
naming scheme for the po4a output files and set the PACKAGE_*
variables used here.
We could have done all translations in a single call to po4a
like the makefile based buildsystem does. While that would
have made the output slightly nicer, this solution offers a
huge performance gain because it can translate the documents
in parallel, which also means that the xsltproc stage does not
have to wait for all translations to be done first.
You might think that the add_custom_command() should list the
actual output files as BYPRODUCTS. This is not true however:
Because the files are not always generated, Ninja will think
missing byproducts mean that the target is out of date - which
is not what we want.
Finally, also add the missing doxygen support. Note that the
packaging script cleans up some md5 and map files created by
doxygen, otherwise it is fairly boring.

This abstracts the joining of paths a bit better than having
basically the same code twice in the Translations module.

This was dropped in autotools as I found no use of the HAVE_PTSNAME_R
macro. Turns out it was typoed as HAVE_PTS_NAME_R. Fix the #ifdef and
add checks to CMake for it.
Closes: #833674

It's not entirely clear if that is useful, but it cannot hurt. We
need to check what is missing to build on foreign systems without
dpkg.

The SOURCE_DIR property is used for the translation building and
was introduced in cmake 3.4

Add support for our GTest based unit tests. By default, CMake will
look in /usr/src/gtest for the external GTest project, but this can
be overriden by defining GTEST_ROOT when invoking cmake.

This seems to be needed for the hebrew translations.

Use the witness/byproducts approach to build the translations. A
byproduct of a command is like an output, but may be older than the
input.
Here, we generate a normal template with headers in the normal way
as a witness (and for Launchpad translations), but we also generate
a .pot-tmp0 template file without a header that gets copied to a
.pot-tmp byproduct only if it changed. This way, the .pot-tmp is
only updated if an actual string translation changed. We also
create a custom target for the .pot file that we'll depend on
later in the overall target creating the mo files to ensure that
the template is build before we try to build mo files.
Then we make the msgmerge depend on the .pot-tmp instead of the .pot
file, which means that msgmerge and msgfmt only get re-run if a string
change occured.

This is really useful stuff to have.

Merge all the per-domain templates into one template file using
msgcomm, stripping any line numbers in the input files, and sorting
the output per file.
This should create reasonably stable .pot and .po files that do not
change just because files move around. It should also be resilient
against some line changes, as long as one translated line is not
moved before/after another translated line.

Rework the arguments to apt_add_translation_domain so a user
can specify TARGETS and SCRIPTS, the latter being Shell scripts.
For each language (TARGETS being C++, SCRIPTS being Shell), a separate
template is generated via xgettext. Those templates are then merged
together by using msgcomm. In case there are no Shell scripts in
the translation domain, msgcomm will receive /dev/null instead of
a shell translation template.
This also reintroduces line numbers, as msgcomm would otherwise
re-order the merged files not only by filename, but also by message
string. It's unclear why it does that, it could just leave strings
within a file alone.
In contrast to the old build system, we use xgettext for shell scripts
instead of bash --dump-strings, as it's just easier to use the same
tool for everything. We also create valid headers.

This makes debugging things easier.

This gets rid of the line numbers, adds the plural keyword,
and makes msgfmt print statistics, so we know how well translated
we are.

I wondered why the template was not rebuilt after I changed a file,
now I have the answer.

This is needed in a lot of places. Also adjust config.h.in to use
it instead of the bare email address.

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.
Gbp-Dch: ignore
|
|
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).
Gbp-Dch: ignore
|
|
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.

If we receive an interrupt, set a flag and do not abort
immediately without waiting for the child. Once the child
exited, exit with an error if the interrupted flag is set.

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.
