| * Fix launching PySide2 from paths with non-ASCII latin charactersFriedemann Kleint2020-09-161-3/+9
| | | | | | | | | | | | | | | | | | | | | | | | QtCore uses QSettings to read the qt.conf file, which uses Latin1 encoding in Qt 5. To match this, use Latin1 encoding for the embedded qt.conf as well, which at least improves the situation for latin characters. Non-latin characters are unfortunately non-fixable in Qt 5.

* feature-select: optimize feature access to the feasible maximumChristian Tismer2020-07-311-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | ** fix: MSVC needs extra sign bit in basewrapper_p.h! Buglet? ** The new feature selection has some tiny overhead. It is about two dict accesses plus a slot access for every tp_(get|set)attro call. The introduction of an explicit `__init_feature__` call allows to optimize this overhead very nicely, because this init is done for each __feature__ import: First, we can remove that tiny overhead completely by not initializing the feature_select module at all if no __feature__ import is used. Second, we can optimize this access further by caching the current module dict. If the dict is unchanged, then the last select_id can be used. This reduces the overhead of frequent calls to a single slot access. Third, we finally cache the select id in unused SbkObjectType bits. That removes the last structure where repeated attribute lookup is used. The overhead is therefore quite small when something is changed. But typically these changes are infrequent. The majority of accesses do change nothing, and this case is now quite much optimized. Change-Id: I7d1a4611a1c19216fd9be8f04457bb18ebd52ab1 Reviewed-by: Christian Tismer <tismer@stackless.com>
* feature-select: allow snake_case instead of camelCase for methodsChristian Tismer2020-07-241-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is the implementation of the first of a series of dynamically selectable features. The decision depends of the following setting at the beginning of a module after PySide2 import: from __feature__ import snake_case For more info, see the Jira issue, section The Principle Of Selectable Features In PySide The crucial problems that are now solved were: - it is not sufficient to patch a type dict, instead the whole `tp_mro` must be walked to rename everything. - tp_getattro must be changed for every existing type. This is done either in shiboken by a changed PyObject_GenericGetAttr or PyObject_SenericGetAttr, or in the generated tp_(get|set)attro functions. An example is included in sources/pyside2/doc/tutorial/expenses. Task-number: PYSIDE-1019 Change-Id: I5f103190be2c884b0b4ad806187f3fef8e6598c9 Reviewed-by: Christian Tismer <tismer@stackless.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Among other files to fix, basewrapper.(cpp|h) was full of uncommon pointer whitespace. After fixing that, I could not resist and fixed also libshiboken, generators, and after acceptance also PySide. Most of the time, this regex worked fine (\w\w+)([*&]+)[ ]*(?![&*]*[/=]) replaced with \1 \2 but everything was checked by hand. I did not touch the shiboken tests which are quite hairy. It turned out that inserting a space between a variable and asterisk causes a crash of shiboken, if the same line contains "CONVERTTOCPP". This was temporarily fixed by adding another space after it. Example.. sources/pyside2/PySide2/glue/qtcore.cpp line 977 QByteArray * cppSelf = %CONVERTTOCPP[QByteArray *](obj); //XXX /|\ omitting this space crashes shiboken! cppgenerator.cpp was special, since it was modified to _generate_ correct pointer whitespace. This caused a few testcases to fail, which had to be adjusted, again. This was difficult since some internal names must end on "*" and generated code normally not. Removing the last errors involved binary search on path sets... Apply C++ 11 fixits to the changed code, where applicable.

* PySide: Allow any existing attribute in the constructorChristian Tismer2019-06-041-16/+39
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are signals and properties which are correctly supported in PySide by the function "fillQtProperties". The structures are introspected by calling "QMetaObject::indexOfSignal" and "QMetaObject::indexOfProperty". By allowing any property, extending the above restriction, we break the Qt API slightly, but have the tremendous advantage of being able to write all needed properties into the constructor call. This approach is a compromize that keeps the attribute calls as they currently are. Supporting real properties where we actually have getter and setter functions would be possible as well, but that would break compatibility very much! It has to be discussed if we want to support a configuration switch that enables this incompatible change. If we would go this far, then I would do this together with changing mixedCase to lower_case. A simple test case has been added.

* libpyside: Port DynamicQMetaObject to QMetaObjectBuilderFriedemann Kleint2018-10-221-6/+5
| | | | | | | | | | | | | | | | | | | | Qt 5 introduces a new class QMetaObjectBuilder for generating dynamic meta objects for use cases like QML. It provides an API to add methods, properties and info and a factory method toMetaObject() to obtain a QMetaObject snapshot reflecting the changes. Replace the DynamicQMetaObject aggregated by TypeUserData by a class MetaObjectBuilder wrapping a QMetaObjectBuilder with dirty-handling. The code to create the binary data of the QMetaObject can then be removed. For plain Qt objects, the wrapped base meta object will be returned (which fixes the bug).

| | | | | | | | | | | | | | | | | | | | | | | | | When building PySide with a debug Python, a lot more problems become visible. They were triggered by some malicious ordering of the shutdown code, which must come *after* the refcounts of the variables are adjusted. The initial issue PYSIDE-585 was caused because the shutdown code is not only used for every created Q*Application, but also for the module shutdown, which deletes qApp_contents too often. Instead of special-casing that or adding some refcount, it was much more intuitive in that context to set qApp_content's refcount to the same value as Py_None, which also is not supposed to be garbage collected. Btw., the reason for the error message is that Py_None has it, too. When we set qApp_content's type to Py_None's type, it inherits the protection code that prevents someone from garbage collecting Py_None.

* Support the qApp macro correctly, final version incl. debugChristian Tismer2017-10-271-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For short the new features: - there is a qApp in QtCore, QtGui and QtWidgets for compatibility, and also in __builtins__ for a true macro-like experience. - if you delete any qApp variable, the Q*Application is reset and you can start over. Long description: There is a qApp macro in Qt5 which is equivalent to Q*Application.instance() . Python does not have macros. Both PyQt5 and PySide2 have an according structure in QtWidgets. In the case of PySide2, the qApp variable is first initialized to None and later to QApplication(). This does not reflect the original sense of the qApp macro, because - it only handles QApplication, - it does not handle destruction. This "macro" should live in QtCore, but both PyQt5 and PySide2 decided to put this in QtWidgets. As a compromize, I propose to put qApp into all three modules, and into __builtins__ as well, so wherever you create an application, you find this "macro" in place. While changing the code, I stumbled over the template set_qapp_parent_for_orphan. I tried to make sense out of it and finally removed it. There were no side effects but bug PYSIDE-85 is gone, now. With some extra effort, I created a singleton qApp that changes itself. This way, a true macro was simulated. Note that this was not possible with a garbage collected variable, and I had to make shiboken aware of this. As the final optimization, I turned qApp also into a fuse variable: Delete any qApp variable and Q*Application will finish when there is no extra reference.

in preparation for a subtree merge. this should not be necessary to do in a separate commit, but git is a tad stupid about following history correctly without it.
