cross-cutting changes to make more of WALA runnable with TeaVM. The biggest change is refactoring to AnalysisCache and friends; since TeaVM does not support SoftReference, I needed to add a layer of interfaces so that I can use a more simpleminded caching implementation for TeaVM. There are other changes to Module and friends to break connections with File and URL, which also cause TeaVM grief. I also organized imports in many places to remove unused types that caused trouble.

Hacks to make WALA run on TeaVM, and hence be able to run in Web browsers. TeaVM has some warts, but overall it is a very nice mechanism to run Java code on the browser. I have examples of analysis actually running in Firefox, which enables supportive tools. So, for those changes that are not ideal, such as dropping the ConcurrentHashMap in ClassHierarchy, we should find a way to support both them and TeaVM, based on demand.

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.

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.
