Summary:
This is unsound but will help the analysis to report less false alarms with the common pattern:
if (a.get() != null) {
a.get().foo();

Summary:
Previously, only the bug type + file name (up to renaming) were taken into
account, which was too coarse. The key is file-independent and provides
additional signal.

Cosmetic changes to the output of `make clean` and `make test-replace`.
Run the inferTraceBugs tests from tests/build_systems/ like other such e2e
tests, so that they can run in parallel with other tests instead of

Summary:
Works the same way as read/write races on fields, except that are more relaxed (er, unsound) in deciding whether two containers may alias.
This is needed to avoid reporting a ton of FP's; full explanation in comments.

This was hardcoded but it's passed as an option to the script. It can be useful to generate text reports from arbitrary json reports, eg:

This was an oversight. The prologue has to be run before capture and analysis
(see eg Infer.run). This sets up a bunch of things that are useful for the

Summary:
The way we represented container writes before was pretty hacky: just use a dummy field for the name of the method that performs the container write.
This diff introduces a new access kind for container writes that is much more structured.
This will make it easier to soundly handle aliasing between containers and support container reads in the near future.
