fix: properly propagate NullPointerState along phi nodes in the NullPointerExceptionAnalysis
2016-12-07 17:56:59 +01:00
edf4f8ed6f
Attempt to fix intraprocedural Nullpointer analysis by respecting phi nodes, and correctly initializing entry variables.
...
Since SSAPhiInstructions are never visited by NullPointerTransferFunctionProvider.TransferFunctionSSAVisitor,
we now respect phi instructions present at a given block by providing additional NodeTransferFunctions, improving precision.
Formerly, meets would lead to incorrect results due to incorrect initialization of initial data flow facts.
These are now properly initialized, interpreting
"State.BOTH" to mean: both "null" and "non-null" are possible values for the given variable, and
"State.UNKNOWN" to be the absurd assertion.
The initial fact at the entry block assumes variables to be BOTH, other blocks are initialy assumed unreachable and hence their variables to be UNKNOWN.

WALA: Provide acces to JSR 308 Annotations via new Class TypeAnnotation.

Access is provided via corresponding methods in FieldImpl, ShrikeCTMethod and ShrikeClass.
Since we do not currently have implementation of these methods for front-ends other than Shrike, these new methods are not yet made available in the corresponding interfaces.

Correct HTML embedded in Javadoc comments
...
Most of the invalid HTML arose from bare "<" and ">" characters.
These should be escaped as "<" and ">" when not intended to
introduce HTML tags. When you have many such characters close
together, "{@literal ...}" is a nice, readable alternative that
automatically escapes its contents. If the text in question is
intended to be a code fragment, then "{@code ...}" is appropriate:
this is essentially equivalent to "<code>{@literal ...}</code>".
There were a few other HTML violations too, but none common enough to
be worth detailing here.

Fix numerous unescaped "<" and ">" in Javadoc @author tags
...
The contents of @author go straight into HTML, just like most other
Javadoc material. So if you want to have a "<foo@bar.com>" e-mail
address as part of the author information, the angle brackets must be
escaped. Here I've opted to do that using "{@code <foo@bar.com>}",
which has some additional styling effects that seem appropriate for
e-mail addresses. We could also have used "<foo@bar.com>" for
escaping without code styling.

Remove incorrect methods from ICFGSupergraph
...
These methods were constructing an IR based on some default
AnalysisOptions, which may not match the options used when constructing
the underlying CallGraph. This mismatch can lead to bad bugs.
Instead of these methods, analyses should get IR directory from the
CGNodes via CGNode.getIR().
Ideally we would fix the methods and not change the interface, but
that would require knowing the right AnalysisOptions, which itself
would necessitate an interface change.
