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.

Most current alerts (https://lgtm.com/rules/1510380685982/alerts/), while technically correct, are likely intentional and harmless. This change keeps only the interesting ones: https://lgtm.com/query/2999122885894714237

1cafec56ad Add condition guard nodes for some switch statements.
We now create condition guard nodes for `cond1` and `cond2` in

```
switch {
case cond1:
  s1
case cond2:
  s2
default:
  s3
}
```

to record the fact that `cond1` is known to be true at `s1` and false at `cond2`, and that `cond2` is known to be true at `s2` and false at `default`.

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.

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.
