- normal case with synchronous and asynchronous mapfn
- a non-callable value is passed as mapfn
- behaviour of various values of thisArg in strict and sloppy mode
- mapfn result is awaited once per iteration
- iterator is closed when mapfn throws
A property in the property bag we want to observe may be a function, in
which case we don't want to treat it as a primitive and create a
toPrimitiveObserver for it.
(Also handle the null case, in which we should fall through to return a
toPrimitiveObserver.)
This was a needs-consensus PR that didn't reach consensus. The
corresponding tests were already removed in f7e6656c.
(Note, the link in the removed comment is wrong; it should point to
https://github.com/tc39/ecma402/issues/374)
Previously, split() would split on whitespace, then the if-condition would
remove `#` - interpreting every word in every comment in the file as a
potential valid feature flag. We want splitlines() here.
Partial-line comments were inadvertently "supported" before, because of
this bug. Instead, support them explicitly by chopping off a `#`
character, anything after it, and any whitespace immediately preceding it.
If a specific Python interpreter is used (e.g. by invoking the script with
"/path/to/python run.py") then we should use the same Python interpreter
to execute scripts in subprocesses, not the one from the environment.
The path to the running Python interpreter is given by sys.executable.
Tests for the process of calculating the reference ISO day for
Temporal.PlainYearMonth and the reference ISO year for
Temporal.PlainMonthDay.

In https://github.com/tc39/proposal-temporal/pull/2474, which achieved
consensus at the TC39 plenary meeting of 2023-01-31, the implementation-
defined steps for Temporal.Calendar.prototype.mergeFields had their
language tightened, to better specify what implementations must do.
This adds tests covering the new spec language, and moves one related test
out of staging.
This is a process allowing contributors to submit well-motivated
proposals to improve test262 using an RFC (Request For Commments)
process which is adapted from a similar process in the Rust community.
In since() and until() methods, we copy the options object with
CopyDataProperties. Previously, its properties could be read in more than
one place (the method itself, and the calendar method), triggering user
code each time. Now, we pass around null-prototype objects with only data
properties.

Previously in a few cases (calendar units in Duration) the value for the
roundingIncrement option had no upper limit, other than having to be
finite. These tests cover a normative change limiting it to 1e9.

The with() methods, as well as PlainYearMonth's since() and until(), were
adjusted to read the receiver's fields before the fields of any objects
provided as arguments. This change is observable, so affects several tests
that test the observed order of operations.
