* Add security header for src/qmlcompilerOlivier De Cannière2025-09-171-0/+1
| | | | | | | | | | | | | | | | | | We assume that QML or JS code comes from a trusted source. Therefore, most files are deemed to be significant even if they parse data. This includes the source code itself but also the associated metadata or cache files. However, the QML compiler also generates C++ code. Extra care needs to be taken with the generator as a vulnerability there could propagate and have a disproportionate effect on the program's security. It is marked as critical.

* aotstats: Keep track of files and modules with no functions or bindingsOlivier De Cannière2024-11-041-0/+10
| | | | | | | | | | | | Before this change, the report presented to the user would be completely silent about them. For the sake of consitency, register each file before trying to compile it. This will then add an entry for empty files and modules. Task-number: QTBUG-124667 Pick-to: 6.8 Change-Id: I502660b7a16a67a173763f9ea2b081cbcceb5658 Reviewed-by: Sami Shalayel <sami.shalayel@qt.io>
* aotstats: Support --only-bytecode and modules with no qml filesOlivier De Cannière2024-11-041-3/+3
| | | | | | | | | | | | | | | | | | | | It is possible to pass --only-bytecode to qmlcachegen. As the name implies, this only generates the bytecode for the qml files and does not compile them. This case was not taken into account which could lead to files commands depend upon not being generated. Therefore, keep track of empty and only-bytecode modules in files generated by cmake and pass them to qmlaotstats upon aggregation such that it can include that information in the report. Also, only pass the arguments specific to aotstats to qmlcachegen if --only-bytecode is not set for that module.

* Compiler: Aggregate and print aotstatsOlivier De Cannière2024-06-011-0/+54
| | | | | | | | | | | | | | | | | | | This patch enables the aggregation and printing of aotstats recorded by qmlcachegen for compiled qml files. The aotstats files for individual qml files are aggregated into module-level aotstats files and then into one global aotstats file. This file is then presented into a more human friendly format. The all_aotstats target can be used to print the collected stats of all the compiled files and modules. Due to CMake configuration errors, the feature has temporarily been disabled on Xcode. This should be fixed before soon. Created QTBUG-125995. Task-number: QTBUG-124667 Change-Id: I0c82142626743e9c1af98516c553f4dd7bc6da13 Reviewed-by: Fabian Kosmale <fabian.kosmale@qt.io>
* Compiler: Record statistics about aot compilationOlivier De Cannière2024-05-281-0/+134
This patch introduces the collection of statistics about the ahead-of-time compilation of functions and bindings to Cpp by qmlcachegen. This is done by having qmlcachegen save an aotstats file for every qml file it compiles. This file contains, for every function and binding, whether the Cpp codegen was successful, its duration and a potential error message Task-number: QTBUG-124667 Change-Id: Iba9a72be04f6642688533a3ae12ea687296c85e1 Reviewed-by: Fabian Kosmale <fabian.kosmale@qt.io>
