[dart-misc] dart sdk / dartium 1.13 indexed_db changes - compound index keys and multi-store transactions broken

[Jim Trainor]

I updated to Dart SDK + Dartium 1.13, on OSX 10.0.5, and discovered that
Dartium's indexed_db implementation appears to have changed. It no longer
supports compound index keys and transactions on multiple object stores.
Anyone have any idea what happened? I was using 1.11 before I updated so
there is a chance that this change happened in 1.12.

It is not a big problem for my larger code base because other browsers do
not support these features therefore I don't depend on them. I do,
however, have tests for each feature that I expect a browser to support, so
that I can keep track of what works where, hence I noticed these changes
immediately.

Bit of a big change for a dot release.

The change in Dartium is that most things are going through JS Interop
rather than through C++ APIs in the browser. So this might be a side effect
of that change. Do you have an example that demonstrates the issue?

If it is a side effect of the js interop change then I’d guess there is a
small issue interpreting list versus scalar arguments passed through the
indexed_db api. There were similar problems with the indexed_db in the
Dart’s earlier days. I’ll make a standalone test and post a bug.
