Fixes https://github.com/Semmle/ql/issues/1572
Adjust mock so it's more aligned with what the flask code actually does. Tests
were passing before, even though we didn't handle the case in real code :\
It's a bit crude to suppress all results in instantiations, but we're
already using this kind of suppression in `PointlessComparison.ql`
(without the `Self`) because there is no convenient alternative. It
means we lose some good results but also suppress a new false positive
in Boost that surfaced after we added support for non-type template
parameters.
If the legacy configuration is only enabled if there are no other
configurations, defining a configuration in an imported library can lead to
unwanted results. For example, code that uses `any(MyTaintKind t).taints(node)`
would *stop* working, if it did not define its own configuration. (this actually
happened to us)
We performed a dist-compare to ensure there is not a performance deg ration by
doing this. Results at https://git.semmle.com/gist/rasmuswl/a1eca07f3a92f5f65ee78d733e5d260e
Tests that were affected by this:
- RockPaperScissors + Simple: new edges because no configuration was defined for
SqlInjectionTaint or CommandInjectionTaint
- CleartextLogging + CleartextStorage: new edges because no configuration was
defined before, AND duplicate deges.
- TestNode: new edges because no configuration was defined before
- PathInjection: Duplicate edges
- TarSlip: Duplicate edges
- CommandInjection: Duplicate edges
- ReflectedXss: Duplicate edges
- SqlInjection: Duplicate edges
- CodeInjection: Duplicate edges
- StackTraceExposure: Duplicate edges
- UnsafeDeserialization: Duplicate edges
- UrlRedirect: Duplicate edges
We don't use a locked-down version of six, so some internal things probably
changed from the version used last time, and the versoin I have installed.
Long term fix would be to use a specific version of six for tests!
Due to internal PR#35123 we now actually run the tests under
`python/ql/test/2/...`
These seems like a regression, since the tests state that N is ok, but A and J
should not be allowed.
For now we can accept them, so we don't block all other Python PRs
Due to internal PR#35123 we now actually run the tests under
`python/ql/test/2/...`
Since we haven't done this in a while, test output has changed a bit. These
changes look perfectly fine.
