* Fix handling of out-of-range year in Date's toISOString()Edward Welbourne2018-07-031-1/+1
| | | | | | | | | | ECMAScript 2015 clarified the handling of out-of-range years, requiring that an exception be raised: http://www.ecma-international.org/ecma-262/7.0/index.html#sec-corrections-and-clarifications-in-ecmascript-2015-with-possible-compatibility-impact http://www.ecma-international.org/ecma-262/7.0/index.html#sec-date.prototype.toisostring Change-Id: I91d76703705f3919d2ee77557e36af362db1adf9 Reviewed-by: Lars Knoll <lars.knoll@qt.io>

Handling of date-times without zone as local time is a correction since edition 5.1 of ECMA-262 (which said to handle it as UTC): http://www.ecma-international.org/ecma-262/7.0/index.html#sec-corrections-and-clarifications-in-ecmascript-2015-with-possible-compatibility-impact We were previously handling both dates and date-times as local time, violating the old spec for both and the revised spec for dates.

Note which defective methods are so because the ECMAScript spec requires those defects, reference my bug report against those defects. Fix currentTime to return a UTC time. Fix getLocalTZA to actually deliver the standard offset, without daylight-saving corrections. Fix DaylightSavingTA(t) to return the difference between current standard time offset and pertinent total offset at time t (explaining why that's the least broken answer), rather than assuming DST is one hour when active. (In some places it's half an hour, in some places two hours; and the bugs in the spec break UTC() and LocalTime() if we only return actual DST offset, without adjusting for historical changes to standard offset.) Fix tests to use actual IANA IDs for zones. Change QTime-to-Time conversion to use a modernish date, for which time-zone data is likely to at least be consistently handled, instead of MakeDay(0, 0, 0); that's (nominal proleptic Gregorian) 2 BC, December 31st (represented denormally) for which any time-zone data we have is artificial and contrived. I chose Cassini's third centennary, as it's not likely to be near any zone transitions and is within the era of sane time-zone data.

* V4: Handle QTime->DateObject conversion betterErik Verbruggen2016-08-101-0/+22
| | | | | | | | | | | | | | | | | | | | | | By specification, date conversion functions for dates before the epoch are not DST corrected. We converted QTime to a QDateTime where we set the date part to Jan. 1, 1970, and then convert that to msecs since the epoch UTC. For places on Earth where they had DST on that day (e.g. Hobart in Australia), strange things happen: conversion from a QTime to DateObject will use DST (because it's after the epoch in local time), but conversions from DateObject to QTime won't use the DST because it's before the epoch (in UTC). Now as everyone knows, a 24-hour clock time has no meaning without a date, only "elapsed time" has. But users still expect to be able to pass QTime to QML/JS. So, we do the conversion on day 0 of month 0 of year 0, and all of it in local time. This gives a stable conversion in both directions, and the values in both C++ and QML/JS are the same for any timezone (with or without DST) on this planet.

* V4: Pass scope around as parameters inside the runtime.Erik Verbruggen2016-06-221-6/+6
| | | | | | | | | | | | | | | | The implementation of many (or all) runtime functions consist of first creating a QV4::Scope, which saves and restores the JS stack pointer. It also prevents tail-calls because of that restoring behavior. In many cases it suffices to do that at the entry-point of the runtime. The return value of a JS function call is now also stored in the scope. Previously, all return values were stored in a ScopedValue, got loaded on return, and immediately stored in another ScopedValue in the caller. This resulted in a lot of stores, where now there is only one store needed, and no extra ScopedValue for every function.
