Summary:
When someone runs --changed-only mode, there is a risk of corrupting the results
for future analyses. The problem is that changed-only mode does not analyze the callers of changed
procedures. If a subsequent analysis relies on the specs of one of these callers, they will be stale
and may give the wrong results. To be concrete, let's say we know `Parent.foo()` calls `Child.bar()` and we do the following rounds of analysis:
Analysis round 1: Analyze all files, including `Parent` and `Child`
Analysis round 2: Analyze `Child.bar()` only with `--changed-only flag`. `Parent.foo()` is now stale.
Analysis round 3: Add procedure `Parent.baz()` that calls `Parent.foo()`, analyze in (any) incremental mode.
The analysis will only analyze `Parent.baz()`. However, the specs for `Parent.foo()` are stale and may give us bad results for `Parent.baz()`. We want the analysis to re-analyze `Parent.baz()`, but before this diff it will not.
This diff fixes this problem by adding a `STALE` status bit to procedure summaries. In `--changed-only` mode,
the callers of a changed procedures are not re-analyzed, but their summaries are marked as stale. For both
`--changed-only` and regular incremental mode, callees of changed procedures that are marked as stale are
re-analyzed even if they have not changed. This is better than a more obvious solution like deleting stale
procedure summaries, since that would force the next analysis to re-analyze all stale procedures even if it
does not need the results for whatever analysis it is doing. This scheme implemented in this diff ensures
that each analysis only does the work that it needs to compute reliable results for its changed procedures.
Summary:
It can be useful in some situations for Infer to exit with an error code in
case it found a bug. A bug is anything Infer reports in infer-out/report.json.
This adds a flag `--fail-on-bug` to the toplevel infer script.

Summary:
Use the new clang plugin that outputs biniou instead of Yojson. This binary format is more compact, which makes the frontend a little faster (5 to 10%).

Summary:
Passing the list of SuppressWarnings annotations detected during the compilation to InferPrint. The next step will be to add support for error filtering in .inferconfig and use the same mechanism. The annotation processor will generate an .inferconfig like config file and use it to suppress the reports.
Summary:
In order to use the annotation processor to detect the classes and methods annotated with `@SuppressWarnings`, we need to modified javac commands of the form:
javac -cp classpath File.java
into:
javac -cp annotations/processor.jar:classpath File.java
This diff is just a non-functional re-factoring step.
Summary:
Procdesc comparison can be fragile because internal variable names
and source positions in a procedure can vary even if the procedure stays exactly the
same. This diff makes pdesc comparisons less fragile by defining structural comparsions
over instructions, nodes and expressions. These structural comparsions work by lazily
creating a mapping between names in the two procdesc's that and checking that the mapped
names are used consistently.
Summary:
Use the map of pointers to find method declarations and build method signatures.
Remove the need for having an extra map for method signatures (and remove that map).
Summary:
Setting up a basic annotation processor. Right now, the processor
just saves a map of class -> methods that should be suppressed. Next, this map
needs to be turned into a .inferconfig file.
Summary: Another step toward getting procedure-level incrementality for Infer. Here, we just assume that *all* procs in a file have changed when the file changes, but we will filter this list using the pd_changed field of the procdesc for each procedure in the future.
Summary: Handler.postDelayed keeps a persistent reference to its Runnable argument that may cause a memory leak if an Activity is reachable from the Runnable.
Summary: The Nullable checker reported FP's when a Nullable field/param was reassigned to a non-Nullable value in the footprint. This diff fixes the problem.
