* Re-arrange qv4identifier{_p.h|.cpp}Ulf Hermann2020-04-151-207/+0
| | | | | | | | | | | | QV4::IdentifierHashData doesn't need to be visible to all the clients. Furthermore, it can be completely inline. The public functions of QV4::IdentifierHash need to be out of line, but the private ones can be all inline. This shouldn't make much of a difference as most of the public functions call at least one private function. Finally, the files should be named by the class names.

* Port from implicit to explicit atomic operationsMarc Mutz2019-07-021-1/+1
| | | | | | | | | | | | The old code used the implicit conversions from QAtomicPointer<T> to T*, and QAtomicInteger<T> to T, and vice versa. The semantics of these differ from the ones std::atomic uses, so we're going to deprecate these, like we did for load() and store(), too. This patch fixes some users of these APIs before we deprecate them. Change-Id: I892d705c22280f1c6fdc62c1777248b44e9c4329 Reviewed-by: Ulf Hermann <ulf.hermann@qt.io>

| | | | | | | | | | | | This is required to support Proxy properly, and at the same time fixes a couple of test failures. The new interface also replaces the old query and queryIndexed virtual interfaces, as those where doing a subset of what getOwnProperty does.

| | | | | | | | The identifier has a backpointer to it's heap object, which could also be a symbol. Change-Id: I976db1424ec66f8e41e6ce4d76620c6b57d94a62 Reviewed-by: Simon Hausmann <simon.hausmann@qt.io>
* Garbage collect identifiersLars Knoll2018-05-021-8/+40
| | | | | | | | | | | | | | | | | | | | | Implemented by storing a backpointer to the Heap object in the identifier. Since identifiers now point back to their originating String or Symbol, we can now easily mark all identifiers that are still in use and collect those that aren't. Since Identifiers are 64bit also add support for holding an array index in there. With that an identifier can describe any kind of property that can be accessed in an object. This helps speed up and simplify some code paths. To make this possible, we need to register all IdentifierHash instances with the identifier table, so that we can properly mark those identifiers.

* use nullptr consistently (clang-tidy)Shawn Rutledge2018-02-261-5/+5
| | | | | | | | | | | | | From now on we prefer nullptr instead of 0 to clarify cases where we are assigning or testing a pointer rather than a numeric zero. Also, replaced cases where 0 was passed as Qt::KeyboardModifiers with Qt::NoModifier (clang-tidy replaced them with nullptr, which waas wrong, so it was just as well to make the tests more readable rather than to revert those lines).

* Optimize named object handlingSimon Hausmann2016-05-261-0/+21
| | | | | | | | | | | | | | | | By storing the object indices of named objects in the CompiledData::Object of a component, we can achieve two things: (1) We can eliminate the hash of vectors in QQmlCompiledData for the object-to-id mapping (2) We can store the mapping from object name to integer object id in the CompilationUnit and share it across different QQmlContextData instances (as long as it is not modified). Also added a new test that verifies the functionality of a .qml file starting with Component{} itself with object names, something that was previously only implicitly tested through some of the examples (corkboards.qml for example).
