Currently InferAnalyze always adds bucket to the message. Later, python code
strips it, but not everywhere. Changes:
1. Since it's easy to not write bucket in ocaml, stop writing them by default.
2. Add option to print them to InferAnalyze and pass it if infer is in debug mode.
Test Plan:
1. Run on openssl, confirm that no bucket info is written to stdout and csv
2. Run on small example in debug mode and see buckets on stdout

Make c frontend understand CXXNullPtrLiteralExpr.
Note that the implementation differs from GNUNullExpr
Test Plan:
Create function that returns nullptr:
int* getPtr() {return nullptr;}
look at specs:
InferPrint infer-out/specs/getPtr\{831F\}.specs
Procedure: getPtr
int *getPtr()
Timestamp: 1

Remove setjmp that is causing problems in the models in linux.
Will investigate and add it again later.
Test Plan: All the models are now created. In particular strcpy, strdup and a few others in the beginning of the file.

Using InferBuiltins.assume previously caused an assertion failure in the analyzer. Fixed this, and fixed the implementation of the assume builtin to block when the assumed condition cannot hold.
Test Plan: Added several new tests.
Summary:

Modeling bypasses the Closeable as resource assumption for `java.io.StringReader`, `java.io.ByteArrayInputStream` and `java.io.ByteArrayOutputStream`.
Test Plan: Infer CI. Some resource leak should also disappear on Instagram.
Summary:
@public
Sorting the fields in structs and classes. Was needed in the backend and forgotten.
Fixes the github issue https://github.com/facebook/infer/issues/90.
Test Plan: Added a new test that shows that we now get a spec for the example from the github issue.
Summary:
@public
Add some logging to the script and capture modules so it is easier to troubleshoot.
What will be logged:
versions of infer, platform, versions of java, build systems etc.
In the future we will add more info that we might find useful while troubleshooting
Test Plan:
run infer with gradle, ant, buck, xcode, mvn and see the logging output
Run symbolic link pointing to infer:
[INFO] Path to infer script /Users/akotulski/tmp/infer_link (/Users/akotulski/infer/infer/bin/infer)
Summary:
@public
The models for Java no longer require to keep the original fields since we now make the union of the fields from the models and the fields from the code to analyze.
Test Plan: Infer CI. No functional change intended.
Summary:
@public
The empty string '' is a valid classpath information. This diff parses it and skips it when detecting the parts of the classpath. This case is happening when analyzing Buck. This one be one possibility why Infer does not load any bytecode in some cases, leading the
TODO: print error message
failure happening with the release (now `Failed to load any Java source code`).
Test Plan: Infer CI.
Summary:
@public
Adds a small example of a Ant project in order to test that there is not regresssion when modifying the toplevel scripts
Test Plan:
cd infer/tests/codetoanalyze/java/infer
ant clean && infer -- ant compile
Summary:
@public
This will enable support for the same set of arguments already supported by the `make` module, e.g. `--frontend-stats`, `--frontend-debug`
Test Plan:
Tested on an Xcode project with the `-fs` argument, and checked that `.astlog` files have been generated on the same location of the .o files
infer -fs -- xcodebuild -workspace Project.xcworkspace -scheme Project -sdk iphonesimulator

Attaching the resource attribute to the object allows to more easily remove this attribute during the symbolic execution when the resource is passed as a argument, e.g. with `res.close()` or when this resource is passed around via a skipped function.
Test Plan: Infer CI.

This adds basic support for function attributes in Sil, and for translating
attributes from the clang frontend to these new Sil attributes. For now only
the sentinel attribute is translated.
Note that attributes normally have parameters, but they are currently missing
from the clang plugin.
Test Plan:
Add
(match Sil.get_sentinel_func_attribute_value (Cfg.Procdesc.get_attributes callee_pdesc).Sil.func_attributes with
| Some _ -> L.out "found sentinel attribute!\n"
| _ -> ());
between lines 947 and 948 of symbExec.ml, then analyze a file containing:
int add_all_ints(int a, ...) __attribute__ ((sentinel));
int foo(void) { return add_all_ints(1, 2, 3, (void *)0); }
then `grep 'found sentinel' infer-out/log/analyzer_out`
-> the sentinel attribute is correctly passed from the frontend to the backend.

- Remove `No such file or directory` unrelated errors when building Infer for Java only:
line 0: cd: infer/../facebook-clang-plugin: No such file or directory
- Remove makefile comments from stdout
Test Plan:
Ran this command without any checkout of `facebook-clang-plugins`
make -C infer java
The misleading error messages are gone.

@public
The new version of Clang 3.6.1 deployed on the `facebook-clang-plugins` repository
3204b9291b
is patched to support the `nullability` annotation described in https://developer.apple.com/swift/blog/?id=25
**Note**: If you build Infer from source, after you pull this change, you'll need to update your checkout of `facebook-clang-plugins` and recompile clang, and this is done through the commands listed in the `INSTALL.md` file
./update-fcp.sh && ../facebook-clang-plugin/clang/setup.sh && ./compile-fcp.sh # run from the root of Infer repo
Test Plan: Tested on an example app containing the `nullability` annotation described by Apple in https://developer.apple.com/swift/blog/?id=25
Summary:
@public
This is a workaround to a clang crash that happens whenever `-fmodules` and `YojsonASTExporter` are used together.
This workaround, uses the `-plugin` argument instead of `-add-plugin` one for the clang frontend, and as a result of that, it overrides the default action of clang, which means no object files are emitted, but just the AST.
To generate the missing data needed by the subsequent building phases of xcodebuild, we run Apple's clang.
Test Plan:
Compiled project containing Pods and `@import`, through a command of the form:
infer -- xcodebuild -workspace project_name.xcworkspace -scheme project_name -sdk iphonesimulator
Summary:
@public
The clang location information is described in an incremental way: each location information is a delta with respect to the previous one in the AST. This is based on a the visit of the AST nodes which corresponds to the order in which the lines are printed with the standard clang AST dump:
clang -cc1 -ast-dump filename.c
This diff adds a preprocessing phase to the front-end so that location information is composed during a visit, and explicit location information is used instead.
In the case of include files, we report the last known location before including the file.
The current file for a function is the file where it is defined. So if a function is entirely defined in a .h file, then the location information will consistently be about the .h file. If instead a function is defined in the source file being analyzed, and some AST nodes come from macro expansion, line information will refer to the original file.
The front-end tests reveal that the location information was incorrect in a few dot files.
Test Plan: arc unit, after having fixed the wrong location in the existing .dot files
Summary:
report_number is zero before the conditions
