* Restore previous QDateTime behavior in DST gapAndreas Buhr2020-12-153-6/+7
| | | | | | | | | | | | | | | | | | | | | | | | Historic QDateTime behavior when being asked to create a QDateTime in the DST gap was to interpret the given date as if it was in the time before that gap, mapping it to a point in time after the gap. This has changed with a04411119ead3d4473e4f0ac4bceedc585977b2f . Since then, the given date is interpreted as if it was in the time after the gap, thus being mapped to a point in time before the gap. This patch restores the historic behavior. This was not caught by Coin because machines ran in timezone "Atlantic/Reykjavik" which does not have DST since 1967. This patch changes tests to always run in "Europe/Oslo". Driveby: Test function "findSpring" did some operations in local time, even though being asked to work in a specific time zone. Fixed that.

* QSocketNotifier: extend API to provide more flexible startupAlex Trotsenko2020-12-111-0/+46
| | | | | | | | | | | | | | | | | | | | | | | | | | Technically, having a single constructor limits the use-cases for this class. We should take into account that: - an opened socket descriptor must be available at the moment of construction; - the constructor unconditionally enables the notifier (the possible solution notifier = new QSocketNotifier(...); notifier->setEnabled(false); is suboptimal due to heavy operations inside the event dispatcher); - for these reasons, QSocketNotifier most often cannot be a member of another class (we have an extra allocation and indirect access). This patch addresses this shortcoming by making it possible to set the socket descriptor at a later point: [ChangeLog][QtCore][QSocketNotifier] Added setSocket() and an additional constructor which requires no socket.

| | | | | | | | | | | | | | | | | | | | Because CBOR strings are encoded in UTF-8, it's possible that the string that won't fit a QString in UTF-16 would still fit QByteArray in UTF-8 (e.g., anything US-ASCII and most Latin text). The previous solution was an improvement because we used to read into a QByteArray then convert the QByteArray to QString, thus using 3x the amount of memory (1x in QByteArray, 2x in QString). The previous commit skipped the middle allocation and made the regular readString() function do the decoding either directly on source memory or by reading in small chunks (16 kB). Future improvement for Qt 6.1: add readStringChunk(char16_t *, qsizetype) so we can do the validation / skipping at O(1) memory.
