hashBits() is used to generate a hash code from the same 64 bits used
to represent a Wren number as a double. When building a map containing
a large number of integer keys, it's important for this to do a good
job scattering the bits across the 32-bit key space.
Alas, it does not. Worse, the benchmark to test this happens to stop
just before the performance falls off a cliff, so this was easy to
overlook.
This replaces it with the hash function V8 uses, which has much better
performance across the numeric range.
The intent of the assert is to ensure that insertEntry() is not called
with an empty entries array because that would cause you to get into a
code path where the entry output parameter is not set. But the assert
didn't correctly check that.
Fix#635.
With the latest XCode it looks like 32 bit builds are deprecated. This
causes build warnings which fail the libuv build. This commit remvoves
the 32 bit arch from the macOS libuv build, and stops building the 32
build on Travis.
This doesn't let you arbitrarily call back into the VM from within
foreign methods. I'm still not sure if that's even a good idea since
God knows what that would mean if you switch fibers while doing that.
But this does allow the very important use case of being able to call
a foreign method from within a call to wrenCall(). In other words,
foreign methods need to always be leaf calls on the call stack, but the
root of that stack can now come from runInterpreter() or wrenCall().
Fix#510.
- quick clean up pass on layout and colors for clarity/legibility
- added logo to the sidebar
- fix various css things like a full height page when content is shorter, so the footer doesn't creep away from the bottom
- start using em instead of px for consistency across devices
- copies files in doc/site/static/ to output
- update output formatting to include potential differences in markdown generator (local generate had >, so cover both to remain consistent)
- copy rss xml (could be in static too, but for now...)
