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
Summary:
Added phase to construct (incomplete) CFG from existing AST.
Individual instructions are not yet translated so any nonempty functions will
result in a runtime exception.
Added some very short examples of LLVM programs.
Summary:
This adds a sentinel check every time a function carrying a sentinel attribute
is called, regardless of whether we have a definition for that function or not.
Summary:
In objC we already prefix field names with classes.
It's better to make it consistent since it'll allow
us to share more code between C++ and objC
Summary:
The json files that were written by json.dump were valid, machine readable but they had no indentation/return lines making them a long single line and hard to read. Dump the json with an indent of
2.

Summary:
Add a partial copy of TextUtils from Android source for commonly used TextUtils.isEmpty method.
Fixes#141
Closes https://github.com/facebook/infer/pull/143
Github Author: Deniz Türkoglu <deniz@spotify.com>
Summary:
Bumping up the version of the libraries javalib and sawja to 2.3.1 and 1.5.1 respectively in order to use the upstream fix about classnames with $$.
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:
This adds support for having lookup from pointer to decl in C frontend
NOTE: with this diff atdgen 1.6 or later is required.
To upgrade atdgen, please run `opam install atdgen.1.6.0`
Summary:
The current way gradle plugin works is by parsing the verbose output to figure out which files to compile. This becomes a problem when the number of files exceed allowed argument parameter
length. Use javac's @sources file instead.
This patch will leave the tempfiles behind (also noted by Jyrki during the review), however I would like to leave that to a follow up commit and first make sure the tool works for people experiencing this problem.
Fixes#22

Summary:
inferTraceBugs filters the bugs to only show those which have a trace attached
to them. However, the number selected by the user would then be used in the
unfiltered list of bugs. This led to sometimes selecting the wrong bug from the
text interface and from the --select option.
