c96cebb022 Make reads(ValueEntity) and writes(ValueEntity) work for fields. 2020-01-14 15:35:18 +00:00

efc72fa01a Remove Entity.getAUse() and replace uses with getAReference(). 
The former had result type `Ident`, so it wouldn't pick up references to methods and fields. Apart from that, it is subsumed by the latter anyway.

121c940ace Teach TRAP writer to truncate strings longer than 1MiB. 
The evaluator cannot in general handle strings that are longer than 1MiB when UTF8-encoded. Similar to other extractors, we now truncate such strings to fit within the size limit.

46c4670796 Make HardcodedCredentials query less noisy. 
Considering "cert" and "account" to be sensitive leads to a massive number of false positives, especially on cockroach and kubernetes.

Henning Makholm
7bc68c4302 Adapt Go tests to codeql test 
These changes make the tests work with the coming `codeql test` support.

The `queries.xml` file defines which extractor the `codeql test`
runner will use to extract databases for the tests. In the future one
will be able to write this information in `qlpack.yml`, but we can't
do that immediately because the _existing_ CodeQL tooling would refuse
to parse a `qlpack.yml` that has the new field in it.
