* Make moc ready for when null byte-arrays have null constData()Edward Welbourne2020-09-171-4/+3
| | | | | | | | | | | Various places in moc relied on the magic behavior of QByteArray, that provided a non-null pointer to a null byte when the byte array was null, resulting in crashes when QT5_NULL_STRINGS is turned off. Fixed them to cope with this (and optimised out some pointless effort, when empty QByteArrays are involved, in the process).

* Enforce complete method types of QML registered classesFabian Kosmale2020-09-031-1/+11
| | | | | | | | | | | For QML, we like to avoid doing string to type lookups at runtime as much as possible. Therefore, QML registration macros like QML_ELEMENT now cause moc to require complete types not only for properties, but also for all methods known to the metatype system.

| | | | | | | | | | | | | | | Add a new BINDABLE declaration to the Q_PROPERTY() macro that tells moc where to find the QBindable for the property. Add a QUntypedBindable base class to QBindable<T> that gives access to generic functionality and checks argument compatibility at runtime. QBindable<T> will still do static checking at compile time. Add QMetaProperty::isBindable() and QMetaProperty::bindable() to be able to dynamically access the binding functionality.

* moc: Fix QProperty code generationFabian Kosmale2020-06-251-0/+7
| | | | | | | | | | | | | | | | This addresses two issues: 1. The generated code for QNotifiedProperty<T, ...> was broken when T is a pointer. Notably, const S* & is not a constant reference to S*. This is addressed by consistently using T const& instead of const T&. 2. The Q_PRIVATE_QPROPERTY approach assumed that the property name and the getter are equal. This does break when they are not, and we are unable to change either of them due to API compatibility concerns. An example of this would be QQuickItem's parent property with a parentItem getter. Therefore, we now allow the usage of NAME to override the name of the property. Change-Id: Idf2e85576c74371b5b0f6db15dbe6f2d17c5e33d Reviewed-by: Ulf Hermann <ulf.hermann@qt.io>

* MetaObject: Store the QMetaType of the methodsFabian Kosmale2020-06-021-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | This does the analog of 46f407126ef3e94d59254012cdc34d6a4ad2faf2 for the methods we care about (signals, slots, Q_INVOKABLEs). In addition to the actual QMetaType, we store an array with offsets so that we later can do a mapping from methodIndex to metatype. The newly added QMetaMethod::{return,parameter}MetaType methods can then be used to retrieve the metatypes. This does however require that all involved types are complete. This is unfortunately not a feasible requirement. Thus, we only populate the metatype array on a best effort basis. For any incomplete type, we store QMetaType::Unknown. Then, when accessing the metatype, we fall back to the old string based code base if it's Unknown.

* Allow for private properties to be implemented using QPropertySimon Hausmann2020-04-301-1/+15
| | | | | | | | | | | | | | | | | | | | | | Recently the moc learned that Q_PROPERTY(int x ...) can mean that "x" is implemented as QProperty and then allows installing bindings, etc. - this works by scanning the same class' members. For our own use of QProperty, we need to place the QProperty member itself into the d-pointer to be able to maintain the ability to add new properties without breaking binary compatibility. That however means that moc can't know that a certain property is backed by QProperty - we don't scan the members of the private class. As a workaround, this change enables the syntax where the property type used in Q_PRIVATE_PROPERTY may be wrapped with QProperty<T>. In addition this patch fixes the compilation of such declared properties by ensuring the accessor prefix (t->$accessor) is applied also for the QProperty related meta call variants.

This is useful for build tools (like CMake) to know when moc should be re-ran. In the future, it might also be useful for ccache (teach ccache not to re-run moc when not necessary). The dependency list contains: the original source file, the passed --include files (like moc_predefs.h), the include files that were discovered while preprocessing the source file, and the plugin metadata json files listed in Q_PLUGIN_METADATA macros. The file paths are encoded using QFile::encodeName, so using the local 8-bit encoding. The paths are also escaped (so ' ' replaced by '\ ', '$' by '$$', etc) according to the Make-style rules as described in clang's dep file generator https://github.com/llvm/llvm-project/blob/release/9.x/clang/lib/Frontend/DependencyFile.cpp#L233 For reference, the equivalent Ninja depfile parser source code can be found at https://github.com/ninja-build/ninja/blob/v1.9.0/src/depfile_parser.in.cc#L37 Additional options that can be passed: --dep-file-path - to change the location where the dep file should be generated. --dep-file-rule-name - to change the rule name (first line) of the dep file (useful when no -o option is specified, so output goes to stdout). Encoding story. Note that moc doesn't handle non-local-8-bit characters properly when processing include directives at the preprocessor step. Specifically the content of the main input file is read as a raw byte array (which can be UTF-8 encoded) and then each include directive is resolved via Preprocessor::resolveInclude(), which calls QString::fromLocal8Bit(). Because moc uses the QtBootstrap library, only a limited set of codecs are available: various UTF 8 / 16 / 32 codecs and QLatin1Codec (ISO-8859-15). This means that on Windows, if the source input file is UTF-8 encoded, and contains include names with UTF-8 characters (like an emoji or any character >= 127 that is not in the QLatin1 codec), moc will fail to resolve and process that include, and thus no dep file entry will be created either. On macOS / QNX / WASM the main locale is UTF-8, so file content and paths will be processed correctly (hardcoded via QT_LOCALE_IS_UTF8 in src/corelib/codecs/qtextcodec_p.h). On Linux it will depend on the current locale / encoding set, and if that encoding is one of the ones supported above. UTF-8 should work fine. [ChangeLog][QtCore][moc] moc can now output a ".d" dep file that can be consumed by other build systems.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A recurring problem with the Q_NAMESPACE macro is that it declares an object (staticMetaObject) in the surrounding namespace. That object lacks any export/import qualification to make it usable with shared libraries. Introduce therefore another macro to work around this issue, allowing the user to prefix the object with an exporting macro, f.i. like this: Q_NAMESPACE_EXPORT(Q_CORE_EXPORT) The old macro can simply then be rewritten in terms of this new one, supplying an empty export macro. Note that NOT passing an argument to a macro expecting one is well defined behavior in C99 -- the macro will expand an empty token. Of course, MSVC doesn't like this and emits warnings. As a workaround, use a variadic macro. [ChangeLog][QtCore] Added the new Q_NAMESPACE_EXPORT macro. It can be used just like Q_NAMESPACE to add meta-object information to a namespace; however it also supports exporting of such information from shared libraries. [ChangeLog][Potentially Source-Incompatible Changes] Prefixing Q_NAMESPACE with an export macro may no longer work. Use the new Q_NAMESPACE_EXPORT macro for that use case.

* moc: Add a standard way of specifying a URI as part of Q_PLUGIN_METADATAUlf Hermann2019-04-111-0/+4
| | | | | | | | | | | | | | | | | | | | | | Usually, when you load a plugin, you don't want to load just any plugin that fulfills a given interface, but rather a specific one. When loading dynamic plugins you can differentiate the plugins by file name. This doesn't work in the static case, and file names are also separate from the plugin metadata shipped inside the plugin files. To solve this problem, different hacks have been developed in various places. QML extension plugins add a special property "uri" via the -M option of moc, QML debug plugins expect you to add a json file with an array of "Keys", Qt Creator plugins have a "Name" in their json files, etc. By allowing the identifier for the plugin to be specified inline with the metadata declaration we can make many of the above workarounds obsolete and provide a clean way for users to find their plugins.

* moc: Fix parsing of [[deprecated]] enum valuesOliver Wolff2019-03-111-0/+1
| | | | | | | | | | | | | | | | moc now successfully parses enum values, that have been deprecated with [[deprecated]]. This is valid c++17 and should be handled correctly. By adding that functionality it is possible to parse Windows headers which use this deprecation mechanism. To make sure, that moc works correctly even on compilers that do not support deprecated enum values yet, the auto test explicitly uses [[deprecated]] enum values during moc run.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | C++11 added the new enum class key as well as enum struct. While the former is likely the most known and used, the later can be used in the same contexts and with the same effects. Currently moc doesn't parse enum struct while it does for enum class. This patch fixes this. [ChangeLog][moc] moc now parses enum struct the same way as enum class therefore that keyword can be used with the Q_ENUM macro as well as Q_FLAG and Q_DECLARE_FLAGS.
