acoustid_fingerprint is now a normal attribute of File and always available. Adding and removing the file to and from the AcoustIDManager is now completely handled in File.
- QSettings object needs special care, as file was re-created on exit
- Append a cleanup function as soon as possible to ensure temporary dirs & files are removed in any case
- prefer addCleanup() over tearDown(), keeping creation and cleanup together
This also seems not only on the macOS version but also on the Python build being used. On the build server with macOS 10.15 this works with the Python binaries provided on the server, but fails with official binaries from python.org.
Before introduction of new functions, we had a pattern: "name" script function was defined by "func_name"
Recent patches changed this, introducing inconsistencies.
Also we have inmulti and lenmulti, so stick to this scheme for getmulti and others.
func_find_str -> func_find
find_str -> find
func_reverse_str -> func_reverse
reverse_str -> reverse
func_get_multi -> func_getmulti
func_foreach_multi -> func_foreach
func_while_loop -> func_while
func_map_multi -> func_map
Some of Picard's tag names allow an additional description separated by a colon, e.g. "comment:desc". In case the description part is empty and the tag ends on a colon this is now treated the same as without any colon. So "lyrics" and "lyrics:" are the same tag.
Handling this in Metadata makes this change immediately available in scripting and to all formats. Script using both forms will still work.
The version identifier was previously compared alphabetically, which fails for e.g. "dev" < "alpha".
Implement proper version comparison by introducing a Version class (inherited from tuple).
This omits the dot before the version identifier. Avoids setuptools warning about version normalization for alpha, beta and rc versions.
Note that it is still ".dev1", this is also according to PEP 440.
For Picard versions support the version identifiers 'alpha', 'beta' and 'rc' again (in addition to 'final' and 'dev'). This used to be supported, but got lost at some point
Long version strings will be e.g. 2.3.0beta2. If the shortened string is generated the idenfitiers for alpha and beta will be shortened to 'a' and 'b' (e.g. 2.3.0b2). This confirms to pre-release versioning is defined in PEP 440.
With this change backslashes can be used in filenames on systems other than Windows. Only if Windows compatibility is activated backslashes will be replaced as before.
