When XCA started in 2002, there were no C++ initializers.
Drop explicit initializers from the constructors.
- Fix indentations of section declarators.
- Replace NULL by nullptr when feasible.
- Sort private section: properties first, then methods.
XCA now supports both, Qt6 and Qt5 down to Qt-5.2
Use CMAKE_PREFIX_PATH to point to the QT dompiler directory like
$ cmake -B build -DCMAKE_PREFIX_PATH=$HOME/6.3.1/gcc_64
New classes:
- database_model: Manage the database tables (keys, req, cert, crl, templ)
extracted from widgets/MW_database.cpp
- arguments: parse commandline, dynamically create help text
The DbTransaction class automatically rolls back when the scope
is left (destructor) and no commit happenned.
Every transaction begin will increment the counter,
each commit/rollback will decrement it. Only if all transactions
finished with a commit, a final database commit will be performed.
