Summary:
The models for InputStreamReader and OutputStreamWriter are taking into consideration the charset passed as parameter in order to follow the exception branch when the charset is not valid. However, the previsous models were only considering encoding literals with uppercase letters. This diff adds the lowercase encoding names to the list.
Closes https://github.com/facebook/infer/issues/127
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
The models for Java no longer require to keep the original fields since we now make the union of the fields from the models and the fields from the code to analyze.
Test Plan: Infer CI. No functional change intended.
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.
