If the pakcage manager fails in some way, convert to a readable
error message instead of leaking the exception to the caller
(which produces a traceback, which is harder to read and less
informative)
- point to main Calamares site in the 'part of' headers instead
of to github (this is the "this file is part of Calamares"
opening line for most files).
- remove boilerplate from all source files, CMake modules and completions,
this is the 3-paragraph summary of the GPL-3.0-or-later, which has
a meaning entirely covered by the SPDX tag.
- for remove and localInstall, add support for pre- and post-
scripts like there already was for install.
This feels like there's code duplication going on, but I haven't
thought of an elegant way to distinguish the available operations
so that I can pass around functions instead.
Also make install for yum and dnf follow the documented syntax: options
(-y) before the command (install), even though yum and dnf also accept
the other order. This also makes it consistent with remove.
- Count only the packages that will be changed, given the current
locale settings.
- Preserve global storage unchanged (don't remove any locale-packages).
This, kids, is why you don't switch writing C++ and Python too often.
The C++ code isn't a syntax error in Python, although this would fail
at runtime.
Update documentation, add a new key *skip_if_no_internet* to support
systems that **recommend** having an internet connection (but don't
require it), and which also use the packages module. This prevents
a long delay while the package manager tries to access the internet
and times out (repeatedly).
Existing configurations are unchanged.
- Check for 'list' when it's actually a 'dict' is strange.
Reverse logic to consider 'str' a package name and everything
else is special.
- Refactor to handle the difference between package names and
packages-with-script-data in one place.
- Add code and config documentation.
- Switch sample configurations to dummy-backend.
if the key "install" was used, the install would crash as the backwards
compatibility checks were incorrect. Fixed a typo in the run function so
pre- and post-install hooks now work correctly
