* Remove most compiler warnings about missing overridesLars Knoll2020-09-111-1/+1
| | | | | | | | | | | | Remove around 1000 compiler warnings about missing overrides in our auto tests. This significantly reduce the compiler warning noise in our auto tests, so that one can actually better see the real problems inbetween.

* tst_QStringConverter: fix some deprecation warningsEdward Welbourne2020-08-071-10/+11
| | | | | | | QString's fromUtf16() prefers char16_t data over ushort. Change-Id: Ib20c5afa09ceabb4e91fe434b6a057edb4739a53 Reviewed-by: Lars Knoll <lars.knoll@qt.io>
* Disable deprecation warnings in some testsTor Arne Vestbø2020-07-291-0/+3
| | | | | | | | The tests are testing deprecated functionality, which we still want to test. Change-Id: Iad6ed35800896170c17fe019c7a6ecda22398ac3 Reviewed-by: Volker Hilsheimer <volker.hilsheimer@qt.io>

* Add explicit encode()/decode() methods to QStringConverterLars Knoll2020-06-261-0/+12
| | | | | | | | | The functional style interface is nice, but does feel alien in some contexts, so better also have explicit encode and decode methods.

* Streamline the code in the conversion to and from utf8Lars Knoll2020-05-141-8/+0
| | | | | | | | | | | | | Move pre/and post condition handling out of the main loop to make that one as fast as possible. Remove special handling of a corner case when the input length is zero, where the utf8 decoder did something else than all other decoders.

* Document the string converter classesLars Knoll2020-05-141-10/+10
| | | | | | | | | | Document QStringConverter, QStringDecoder and QStringEncoder. In addition, do some touches to the API, renaming one enum value, add a flags argument to one constructor and make some members private.

| | | | | | | | Add static methods that allow converting between a name for an encoding and the Encoding enum. Change-Id: I12bc503cf757ea31d3ca8d5e1f1216efddcb16d4 Reviewed-by: Thiago Macieira <thiago.macieira@intel.com>
* Construct a string converter by nameLars Knoll2020-05-141-0/+27
| | | | | | | | | | | Add a constructor, that allows constructing a string converter by name. This is required in some cases and also makes it possible to (in the future) extend the API to 3rd party encodings. Also add a name() accessor.

* Clean up the Flag handling in QStringConverterLars Knoll2020-05-141-33/+33
| | | | | | | | | | | | | | | IgnoreHeader was a rather badly defined enum, in addition the utf8 and utf16 codecs where handling BOMs somewhat different for stateless decoding. Fix this by introducing explicit flags for writing a bom when encoding and not skipping the initial bom when decoding. Source compatibility for QTextCodec is done with a couple of static constexpr variables. Change-Id: I0b2d94f84c937cec1e0494c16ef448c00382691d Reviewed-by: Thiago Macieira <thiago.macieira@intel.com>
* Start work on a new API to replace QTextCodecLars Knoll2020-05-144-0/+1607
The new QStringEncoder and QStringDecoder classes (with a common QStringConverter base class) are there to replace QTextCodec in Qt 6. It currently uses a trivial wrapper around the utf encoding functionality. Added some autotests, mostly copied from the text codec tests.
