* Ensure QLocale's shared C-locale QLocalePrivate is never deletedTor Arne Vestbø2013-11-041-3/+7
| | | | | | | | | | | | | | | | | Other static data such as QTextStream might be initialized before the static C-locale, in which case QLocale would adopt c_private and bump the ref-count to 2, only to see it reset back to 1 when the c_locale's static initialization happened. The result was that at application shutdown the ref-count would fall down to 0, and we tried deleting the static data. This issue was observed with clang in a debug build, where the c_private is initialized at runtime.

* QDateTime - Fix round-trip of second occurrence timesJohn Layt2013-09-272-15/+55
| | | | | | | | | | | | | | | | | | | | | | | At the Daylight Tme to Standard Time transition, the local time repeats itself, i.e. 2am occurs twice. Qt's behavior when setting this using the local time is ambiguous, as it depends on the system implementation of mktime, which behaves differently on different platforms. Currently this behavior remains undefined. When setting using an msecs or time_t value however we can determine the correct instance to use and cache it to ensure that any conversion back from local time to msecs is performed consistantly on all platforms. Note that caching this value will result in any calculations being wrong should the system time zone change, or its rules change. This will be fixed in Qt 5.3 when the system time zone change signal is implemented and QDateTime switches to using QTimeZone instead of mktime to provide consistnt behavior across platforms. The QTimeZone spec does not require this fix as it already caches the correct offset in setMSecsFromEpoch().

This change updates support to the latest version of CLDR, fixes the treatment of years, and defaults to ignoring any new format codes added in the future. Note that this change cannot have auto tests written as the system locale formats change between versions of OSX. Testing must be done manually by changing system locale and formats.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Implement the new QTimeZone class based on the Olsen Time Zone ID's. This is the base implementation and does not include the Platform backends which are implemented separately. This change does include a default UTC backed to be used if no Platform backend is available, i.e. if QT_NO_SYSTEMLOCALE is set and ICU is not configured. This backend also provides a default set of time zones in the standard "UTC+00:00" offset format that are guaranteed to always exist regardless of the Platform backend. This change includes conversion functions between the Olsen ID's and Windows ID's using a conversion table based on Unicode CLDR data. This is implemented for all platforms for scenarios such as a Linux program needing to communicate with a Windows Exchange Server using the Windows ID. The CLDR conversion table is included under the UNICODE license, see http://unicode.org/copyright.html for details. [ChangeLog][QtCore][QTimeZone] Added new QTimeZone class to support time tone calculations using the host platform time zone database and the Olsen time zone ID's.

Currently QDateTime ignores this gap and considers the time to be valid and able to be manipulated. This change respects the transition, so any time set in the missing hour is considered invalid, and any date maths returns valid results. The validity in the current time zone needs to be checked every time isValid() is called in case the system time zone has changed since the last time it was checked. This is done by calling mktime to check the returned result matches the expected result. This could be very inefficient, but the returned offset value is cached each time so mktime is not required to be called again within each method call, effectively meaning mktime is called the same number of times by each method. Note that this means any new methods added must be careful to ensure either isValid() or refreshLocalTime() is called first by any method needing to use the UTC value. [ChangeLog][QtCore][QDateTime] The Standard Time to Daylight Time transition for Qt::LocalTime is now handled correctly. Any date set in the "missing" hour is now considered invalid. All date math results that fall into the missing hour will be automatically adjusted to a valid time in the following hour.
