* QCalendar: Delete registered calendar backends on program exitIevgenii Meshcheriakov2021-08-061-2/+5
| | | | | | | | | Add code to check if the calendar registry is destroyed to all QCalendar methods that dereference QCalendarBackend pointer. Pick-to: 6.2 Change-Id: I9b562355e2e0579396b52968f6065c6927cc9ca8 Reviewed-by: Edward Welbourne <edward.welbourne@qt.io>
* QCalendar: Thread-safe calendar backend registrationIevgenii Meshcheriakov2021-08-061-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | All calendar backend accounting was moved into QCalendarRegistry class (renamed from Registry). Calendar backends are no longer registered inside constructors, because in multithreaded environment this may lead to incompletely initialized instances becoming visible via QCalendar API in multithreaded environment. All system backends are registered by QCalendarRegistry itself when they are needed. New method QCalendarBackend::registerCustomBackend() is provided to register any 3rd-party calendar backends. Registration by names was also simplified. The list of names is now passed to QCalendarBackend::registerCustomBackend(). The checks are provided to ensure that all system backends have non-conflicting names. Name conflicts for custom backends are resolved in favor of earlier registered backends, as it is already the case in the existing code. The documentation was updated to reflect that. Method QCalendarBackend::names() was added to query the list of names associated with a backend after it is registered. Calendar backend deregistration was completely removed because it is not possible to perform it safely without reference counting.

* QCalendarBackend: Use QAnyStringView to create backends by nameIevgenii Meshcheriakov2021-07-271-0/+2
| | | | | | | | | | | | | | Combine two implementations of QCalendarBackend::byName() accepting QStringView and QLatin1String arguments into one accepting QAnyStringView to reduce code duplication. Add a note to QCalendar constructors accepting strings to do the same for Qt 7.

* Provide calendar backends with a unique IDEdward Welbourne2021-02-181-0/+1
| | | | | | | | | | | | | | | | | | | | Registration by ID allows for detection of duplicate instantiation of built-in back-ends, which can be detected and flagged by setting the ID to ~size_t(0) instead of the enum value for which it sought to be registered. A new method, calendarId(), is provided to access this; while the old calendarSystem() becomes non-virtual, as it can be inferred (when registration was successful) from the ID. Make registration by name or alias conditional on successful registration by ID. Previously, failed registration by name precluded registration by ID, which now becomes the authoritative registration. This incidentally makes it possible to add a QCalendar constructor taking the unique ID of a backend, for use in conjunction with custom calendar implementations.

* Add support for calendars beside GregorianSoroush Rabiei2019-08-201-0/+174
Add QCalendarBackend as a base class for calendar implementations and QCalendar as a facade via which to access it. QDate's implicit implementation of the Gregorian calendar becomes QGregorianCalendar and QDate methods now support choice of calendar. Convert QLocale's CLDR data for month names to a locale-data component of each supported calendar and relevant QLocale methods now support choice of calendar. Adapt Python scripts for locale data generation to extract month name data from CLDR (keeping on version v35.1) into the new calendar-locale files. The locale data for the Gregorian calendar is held in a Roman calendar base, for sharing with other calendars. Add tests for basic uses of the new API. [ChangeLog][QtCore][QCalendar] Added QCalendar to support diverse calendars, supported by implementing QCalendarBackend. [ChangeLog][QtCore][QDate] Allow choice of calendar in various operations, with Gregorian remaining the default.
