Summary:
@public
Previously, if the close() method was throwing an exception, then code overriding the file attribute with a mem attribute would be skipped, resulting in reporting a wrong resource leak. This diff fixes this.
Test Plan: Added new end-to-end tests which would previously have been failing
Summary:
@public
Using InferBuiltins.assume previously caused an assertion failure in the analyzer. Fixed this, and fixed the implementation of the assume builtin to block when the assumed condition cannot hold.
Test Plan: Added several new tests.
Summary:
@public
Modeling bypasses the Closeable as resource assumption for `java.io.StringReader`, `java.io.ByteArrayInputStream` and `java.io.ByteArrayOutputStream`.
Test Plan: Infer CI. Some resource leak should also disappear on Instagram.
Summary:
@public
Adds a small example of a Ant project in order to test that there is not regresssion when modifying the toplevel scripts
Test Plan:
cd infer/tests/codetoanalyze/java/infer
ant clean && infer -- ant compile
Summary:
@public
Attaching the resource attribute to the object allows to more easily remove this attribute during the symbolic execution when the resource is passed as a argument, e.g. with `res.close()` or when this resource is passed around via a skipped function.
Test Plan: Infer CI.
