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.
Summary:
The @NonNull annotation, with camel case, can now be used to inform Eradicate that some fields that are not initialized by the constructor can be initialized by other means, e.g. via dependency injection.
Summary:
This test was actually testing: "at least one Field not initialized error is found" where we actualy want to test "exactly one Field not initialized error is found". The case of @Inject was also missing from the tests.
Summary:
see title. It will make number of arguments
less ridiculous and make it easier to share C/C++ structs.
Another diff that adds base class information for C++ will
follow.
This change is big enough to deserve separate diff
Summary:
This diff allows to use to make Infer failing when using the function `failwith`. This is especially useful to use while applying complex refactoring.
Summary: Infer cannot tell if a procdesc has changed across procedure runs. If we want procedure-level incrementality, it has to know how to compute this information. This diff implements this capability by comparing a procdesc to an existing one before it is saved to disk, and marking the new one as unchanged if applicable.
Summary:
Handle C++ method declarations and create cfgs for them.
Doesn't do:
Method calls (CXXMethodCall)
Using `this` expression in methods (including implicit ones)
Summary:
Refactor of creating method signatures. First step to use the map of pointers to find method declarations.
The idea is to have a function that creates a method signature from a declaration, later we can get the declaration from a pointer
and use this function to retrieve the method signature.

Summary:
Add basic translation for C++ `new` keyword.
Currently, it's modeled as simple `malloc` call.
Following constructs are still not working properly:
- array new `new [size_expr]`
- run initializer attached to `new` (such as `new int(5)`)
- `delete[]`
Summary:
When detecting a resource leak, Infer used to raise an Leak exception and then prevent the specs to be computed for the paths containing a leak. This diff prevents resource leak to stop the analysis.
Summary:
1. Unify the code now that MemberExpr has more information available and it can be shared with ObjCIvarRefExpr
2. Use type from decl_ref instead of expression type. For methods, expression type is useless (`<bound something something`>). For fields it should be the same
Summary:
No longer swallow compilation failures for javac. Before this diff, the compilation failures where raised:
> infer -- javac Test.java
Test.java:5: error: ';' expected
static String str = "Hello"
^
1 error
but the exit code was incorrect:
> echo $?
0
With this diff, the failing command is printed in standard error:
> infer -- javac Test.java
Javac compilation error with:
['javac', '-g', 'Test.java', '-J-Duser.language=en']
and the exit code is different from 0.
> echo $?
1
Summary:
Creating a persistent reference to an Activity leads to a nasty form of memory leaks (see http://android-developers.blogspot.com/2009/01/avoiding-memory-leaks.html, https://corner.squareup.com/2015/05/leak-canary.html). There are many ways to create a bad persistent reference to an Activity, but the most obvious one is via a static field.
This diff implements a very simple form of Activity leak checking by inspecting postconditions to see if a subtype of Activity is reachable from a static field (and it reports an error if so). This is a very simple and limited form of leak checking that does not understand the Android lifecycle at all. In particular, if one creates a persistent reference to an Activity and then nulls it out in `onDestroy` (a reasonably common pattern), this approach will wrongly report a bug.
Summary:
The methods in objc can have the same name in the same class, but one be instance and the other class,
so that we need to take the instance flag into account when defining unique names for ObjC methods.
Summary:
This is mostly useful to authors of annotation processors and
`javac`-based static analysis tools. The nullable return models
cover these packages pretty comprehensively (with the exception
of the various visitor classes). The non-nullable parameter models
are mostly there to help make the nullable return models more useful,
as some codepaths will pass a nullable object to one of the utility
classes but never actually invoke a method on the nullable object itself.
Summary:
While `-results_dir` is still the main place to look for specs files and to write reports,
it's necessary to load specs from multiple folders because some build tools that run Infer with a target-level granularity may need to move specs files around in order to get complete reports, whereas with this change they just need to keep track of the `specs` folders generated for each target, and pass them through `-lib dir1 -lib dir2 ... -lib dirN`
Summary:
Buck is creating javac compilation commands with arguments of the form:
-Opt={"list": ["pif", "paf", "pouf"]}
While converting command lines from bash to python, these option gets split into
['-Opt={"list":', '["pif",', '"paf",', '"pouf"]}']
instead of:
['-Opt={"list": ["pif", "paf", "pouf"]}']
which create the compilation to fail when running Infer even though the original files are compiling correctly.
Summary:
The symbolic execution was not stopping in case an unitialized dangling pointer was
passed to a function and then dereferenced inside the callee.
What would happen is that a wrong footprint would be added to the unititialized pointer
at the end of the function call in the caller proposition.
This checks that if we do:
frame * new_footprint
checks that we do not add heap predicates to the frame into uninitialized local variables.
If we can identify the variable then we raise a danglind pointer dereference. If instead
we cannot give a good explanation we give an internal error.
The latter case should be temporary. We should find a general way to raise dangling pointer
deref instead of the internal error.
I also fixed the model of getc that was the way I found the problem.
Summary:
Update fcp version and make infer build with it.
It's not using new features yet, diffs will follow.
New stuff:
Proper type information in form of pointer->type
Expose more information about cxx classes (superclass info)
Add pointers to objc method decls when possible
Summary:
This is small code cleanup of the code to report leaks. No functional changes, just removing code that is longer used and reorganising the control flow.
Summary:
This commit is the result of
`find infer/src -name '*.ml' -or -name '*.mli' -exec ocp-indent -i \{\} \;`
and
`INFER_CHECK_COPYRIGHT=1 InferPrint`
Summary:
The old scheme for pruning away garbage from abducted retvars/abducted params passed by ref failed to eliminate garbage in the pure constraints (pi). This occasionally caused PRECONDITION_NOT_FOUND errors that stop the analysis.
Summary:
In preparation for C++ methods, we need to have type with
class, method, mangled (for overloading?)
1. Change objc method to support it
2. Do some renames to be less confusing
