* Remove the use of Q_QML_PRIVATE_EXPORTAlexey Edelev2024-01-111-3/+3

* Long live incremental garbage collection in QML!Fabian Kosmale2023-12-201-2/+10
| | | | | | | | | | | | | | | | | The design of the garbage collector is described in src/qml/memory/design.md. The gc and gcdone test helpers are adjusted to drive the gc to completion, even when in incremental mode. Parts of tst_qv4mm and tst_qqmlqt need to run with the incremental gc disabled, as they call gc inside QML and assumes that the GC finishes before returning.

* Change value encoding scheme to make space for larger pointersUlf Hermann2023-01-121-44/+44
| | | | | | | | | | | | | | | | | | On android and on some other platforms, the upper bits of a pointer are significant. We need to store them in our JS value encoding. Shift the bits around to make this happen. We now can store pointers of up to 57 bits. That's enough for everything we've seen so far.

* V4: Mark InternalClass parents when running GCUlf Hermann2022-08-031-0/+2
| | | | | | | | | | | | | | | | We need to preserve them as they notify us about protoId related changes. In order to avoid wasting heap space in case many properties are added and removed from the same object, we put a mechanism in place to rebuild the InternalClass hierarchy if many redundant transitions are detected.

* Rework qmljsrootgenUlf Hermann2021-04-161-3/+3
| | | | | | | | | This way it actually generates interesting data about the JavaScript types, for example the functions of the String prototype. Add a helper method to create a symbol to QJSEngine. This should be generally useful. Change-Id: I6c7b253b9d6cdb61602ceeae0955aed8d942c139 Reviewed-by: Fabian Kosmale <fabian.kosmale@qt.io>
* Move model types into their own libraryUlf Hermann2019-05-021-1/+1
| | | | | | | | | | The model types are not part of the core QML runtime and should only be loaded if you explicitly import them. We cannot enforce that in Qt5 as some of them are available from the QtQml import, but we can change it in Qt6.

* Don't use UINT_MAX as invalid array index in PropertyKeyUlf Hermann2019-04-161-2/+2
| | | | | | | | | | | Technically UINT_MAX is actually a valid array index, although that is an academic problem right now. However, we do have a method isArrayIndex() and should just use that to determine if a PropertyKey is an array index.

* Introduce a new mechanism to iterate over object propertiesLars Knoll2018-08-021-0/+3
| | | | | | | | | | | | | | | | | The old advanceIterator schema was extremely ugly and in addition not flexible enough to support the requirements for Proxy.ownKeys and some of the methods in Object Implemented a new scheme through a OwnPropertyKeys method in the Object VTable that creates and returns an iterator object. Ported QJSValueIterator and for-in to use the new mechanism. There's still many places where we use the old ObjectIterator (that relies on advanceIterator). Those will be ported in subsequent commits. Change-Id: I091a9bea9ff6b2b63630cc336814700757a718be Reviewed-by: Simon Hausmann <simon.hausmann@qt.io>

* Introduce a PropertyKey class that inherits from ValueLars Knoll2018-07-021-0/+120
This will replace Identifier over the next few commits. The advantage of PropertyKey is that it can be stored on the JS stack, so that a GC run won't accidentally clean up the string/symbol referenced by the key.
