The CLI module was lacking unit test coverage and showed some severe
coding style violations, which this patch addresses.
In addition, all uses of qCritical() with untranslatble raw char*
sequences were removed in favor of proper locale strings. These are
written to STDERR through QTextStreams and support output
redirection for testing purposes. With this change, error messages don't
depend on the global Qt logging settings and targets anymore and go
directly to the terminal or into a file if needed.
This patch also fixes a bug discovered during unit test development,
where the extract command would just dump the raw XML contents without
decrypting embedded Salsa20-protected values first, making the XML
export mostly useless, since passwords are scrambled.
Lastly, all CLI commands received a dedicated -h/--help option.
This patch implements a new database wizard to guide users through the process
of setting up a new database and choosing sane encryption settings.
It also reimplements the master key settings to be more
user-friendly. Users can now add, change, or remove individual composite
key components instead of having to set all components at once. This
avoids confusion about a password being reset if the user only wants to
add a key file.
With these changes comes a major refactor of how database composite keys and key
components are handled. Copying of keys is prohibited and each key
exists only once in memory and is referenced via shared pointers. GUI
components for changing individual keys are encapsulated into separate
classes to be more reusable. The password edit and generator widgets
have also been refactored to be more reusable.
Building with -flto caught the fact that we were ignoring the return
value of readMagicNumbers(), which potentially left the value of 'sig2'
uninitialized.
