* CRA review qml/jsruntimeFabian Kosmale2025-09-161-0/+1
| | | | | | | | | | | | | | | | | | This relies heavily on the documented fact that we only support trusted QML/JS content, meaning most files are only significant, not critical. This also extends to the handling of qmlc files (as in compilationunitmapper), as we store them in a user owned, non-shared cache directory – so any vulnerability there would already mean that an attacker has write-priviledges on user data. An exception is ArrayBuffer, which can be used with arbitrary user data, and should create a valid QBA.

* Reduce access to uninitialized scoped allocationsLuca Di Sera2025-07-081-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | `Scope` provides a mean of performing uninitialized scoped allocations on the JS stack. This can generally be unsafe as this form of allocation temporarily leaves an element representing garbage memory on the JS stack, which could be accessed by other parts of the program. Indeed, a set of bugs related to this kind of behavior was recently solved. Hence, to reduce the surface of those kind of bugs, the usages of uninitialized scoped allocations were reduced to a minimum. The solution to the recent set of bugs related to uninitialized scoped allocations introduced a series of `construct` methods that ensure that the uninitialized allocation and the initialization of the allocated elements are performed as a single step of computation, reducing the surface for incorrect usages of those kind of allocations. The solution was expanded by the introduction of new `construct` methods that cover initialization from other types and some different means of initialization that were used around the code-base to work with uninitialized scoped allocations. Similarly, the various allocation methods in `Scope` were subsumed by the new `construct` methods, with the only remaining means of allocation being the uninitialized one that is used as a building block for the `construct` methods. In particular, `Scope` provided three forms of allocation under the various `alloc` methods. The aforementioned uninitialized allocation and an allocation that performed initialization to either the Undefined or the Empty value. The latter two forms of allocation were converted to forms of `construct`. Since they directly map to the same concept of allocation plus initialization, the conversion avoids having two names for the same concept. More specifically, the form of allocation that initialized to the Undefined value was converted to the new `constructUndefined` which keeps the same behavior. The different naming from the basic `construct` methods is justified by the different interface, which doesn't require choosing a initial value, and the different implementation which is built on the more general `construct` methods rather than the lower level allocation routines. The form of allocation that initialized to the Empty value was removed as it was found to be unused in the code-base. The converted allocation methods generally provides the same interface and behavior with the exception of always requiring the user to specify the amount of allocate objects. This is a change compared to the previous interface which allowed a zero-argument version that allocated a single element. The writer of the patch considered the additional terseness inconsequential compared to the required additional code so that the possibility was not preserved. The code related to the converted allocation forms was removed as a consequence of the conversion. The remaining uninitialized allocation form was made private, to avoid general usage outside of `Scope`, and favoring usages of the substitute `construct` methods. A comment that was related to usages of uninitialized scoped allocations was moved to the lower level `jsAlloca`, which forms the basis for those allocations and creates the abovementioned issues, where it was expanded upon. Usages of the non-uninitialized allocation forms around the code-base were modified to use the new `constructUndefined` method. Most usages of the uninitialized allocation form were modified to use the new `construct` methods that were added to replace them. Exceptions were made for those cases where the initialization routine is either very complex or depends on details that shouldn't belong to `Scope` such that they cannot be trivially encapsulated in a `construct` method. Instead, the relevant function or object was friended by `Scope` to allow accesses to the now private form of allocation. Those usages were previously checked and are supposed to be safe but should be scrutinized if they are modified or the code around them is modified. One of the friended functions, `callDatafromJs`, previously offered a default argument that was not made use of in the code-base. The default value for the argument was removed to simplify friending the function, considering the difficulty the language has with friended function with default arguments and considering that it would have required the default value to be moved out of the function definition into a forward declaration in the unrelated header that defines `Scope`. It is expected that the changes will reduce the surface of usage of uninitialized scoped allocations in favor of a slightly safer approach, make the issue that those usages can produce more apparent and generally centralize the usages as much as possible to make them easier to evaluate and keep track of.

* QJSEngine: Treat empty string literals as non-null, empty QStringsLuca Di Sera2024-06-281-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When evaluating a script with `QJSEngine` an empty string literal will be treated as a null string. For example evaluating `""` will produce a string-holding `QJSValue` that produces a null `QString` when the string value is extracted. This is in contrast with the general behavior of `QJSValue`, where directly constructing a `QJSValue` from a null or empty `QString` will produce a `QString` value that is empty but not null. When the engine reads the literal from the string table, it specifically returns a null `QString` for zero-sized strings. This null `QString` will then propagate its null-ness when used to allocate a string, which will in turn propagate all the way up to the returned `QJSValue` that holds the produced string. To align the behavior of a string-holding `QJSValue` produced from the engine to the behavior of a `QJSValue` directly built from a `QString`, the specialized code that produced the original null `QString` was removed, so that an empty string is constructed instead. This partially amends ff0857541d5d391c7c03cce5893b41dd9b35e7fa, which introduced the specialized construction of the null string in relation to another issue. The change was already partially amended in 86379e265e19a078545306d93c59b0d92c04920a, where some of the additional behavior introduced by the original patch was rendered unnecessary by changes in Qt itself. The null string behavior for empty literals that was added as part of the original patch was partly tied to the code removed in the first amendment and is not expected to break the original case anymore due to the changes in the context around it. A test case was added to `tst_QJSEngine` to test the behavior. The test case that was originally added in ff0857541d5d391c7c03cce5893b41dd9b35e7fa, which tested that empty string literals were treated as nulls was modified to align to the new behavior of non-null, empty strings. A slight change was made to the implementation for the String prototype `startsWith` method to adapt it to the changes which exposed a previously existing bug. When `startsWith` was given a position as part of its second argument, this would have been retrieved as a double and then directly passed to `QStringView::mid`, producing an implicit conversion to `qsizetype`. For values that `qsizetype` cannot hold, the result can be different between platforms. In particular, this showed on a ecmascript compliancy test that would now fail on ARM mac platforms. The test would pass infinity as the second argument and an empty literal string as the first in a call to `startsWith`, which, by the spec description should return true. In general, on an ARM mac platform, the conversion would saturate to the nearest integer, a positive value. On such a parameter the call to `mid` would return a null string. Due to the way the `startsWith` implementation for `QStringView` works, this would require the searched for string to be null for the search to return true. Previously, due to literal empty strings being read as null, this would silently pass. On the contrary, on a platform such as x86_64, the implicit cast would generally produce the indefinite integer value, which appears as a negative integer, producing the whole original string on a call to mid, which then would have the correct behavior on a call to `QStringView::startsWith` with regards to the test in question, so that it would generally pass. To avoid the platform specific behavior, the position in double form is now clamped between zero and the length of the string that should be searched, which should generally avoid the unexpected behavior and be relatively consistent between platforms.

* V4: Slim down FunctionObjectUlf Hermann2024-05-141-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Most FunctionObjects do not actually need their custom jsCall members. They will only call the functions from the vtable anyway. FunctionObject can therefore be split into a static and a dynamic variant. Only the dyanmic variant needs to carry (and invoke) the extra pointer. The jsCallWithMetaTypes pointer is completely pointless because none of the dynamic functions actually implement it. Furthermore, the QV4::Function and QV4::ExecutionContext pointers in FunctionObject are only needed by actual JavaScript functions. The builtins that like to be dynamic functions never need them. Therefore, split out another class for this. In the generic FunctionObject, we need the capability to decide at run time whether the function shall be a constructor or not. Add a flag to replace the check for jsCallAsConstructor. Also, where we can, avoid the pessimization of checking whether a function is a constructor before trying to call it as constructor. Rather have the default implementation throw the exception. As a side effect, for most functions we don't need an ExecutionContext anymore. The engine is enough.

* Introduce a new mechanism to iterate over object propertiesLars Knoll2018-08-021-11/+45
| | | | | | | | | | | | | | | | | 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>

| | | | | | | | | Support the new.target meta property in the codegen, and add support for passing the newtarget into the constructor vtable methods and the execution context. Change-Id: I62ea58e5e92d894035a76e35776203e9837c383b Reviewed-by: Simon Hausmann <simon.hausmann@qt.io>
* Prefix vtable methods with virtualLars Knoll2018-07-031-9/+9
| | | | | | | | | Turns out that the overloading of vtable methods and regular ones is problematic in some cases. So let's rather make it explicit which methods are part of the vtable, and which aren't. Change-Id: Ifee32a26104d30f3c82bca8b5a9cdea2d4f4f526 Reviewed-by: Simon Hausmann <simon.hausmann@qt.io>

* Implement a virtual interface for getOwnPropertyLars Knoll2018-06-251-2/+1
| | | | | | | | | | | | 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.
