Summary:
In next diff, we are going to introduce a new mode of nullsafe
(gradual). For testing, we are going to employ the strategy used by jvillard
for Pulse.
In this diff we split tests into two subfolders, one for the default and one for the gradual
mode.
We are planning to make the gradual mode default eventually. For that, most
new features will make sense for gradual mode, and we will mostly evolve
tests for that mode.
As for 'default' mode, we need to preserve tests mostly to ensure we don't introduce
regressions.
Occasionally, we might make changes that make sense for both modes, in
this (expected relatively rare) cases we will make changes to both set
of tests.
An alternative strategy would be to have two sets of issues.exp files,
one for gradual and one for default mode. This has an advantage of each
java file to be always tested twice, but disadvantage is that it will be
harder to write meaningful test code so that it makes sense for both
modes simultaneously.

It's not being worked on and is not in a state where it works.
It would probably better to write this as a script of some kind or else
resurrect this subcommand in a form where it behaves more like a script,
ie fork/execs infer analyses instead of having them be function calls
(but then it might as well *be* a script as it would likely be more
flexible).
In any case...

Summary:
These have proved to be too fragile to maintain as they would often break
compilation of user code. They have been off by default for more than a year
now (D7350715).
Removing the include models shows a more accurate picture of what infer results
look like in production. As such, lots of tests have changed, mostly
biabduction but also in inferbo. SIOF was using include-based models too but
now libc++ is better and iostreams are implemented in a way that SIOF
understands (instead of being magical creatures) so nothing changed there.

Summary:
The default values of config options can sometimes depend on build-time
configuration values. This makes checking that the manuals "remain the same"
trickier as the manuals can be different depending on the platform. This
removes *all* default values from the checked-in manuals. We could be more
fine-grained and scrub only the values that are susceptible to change but for
now this is probably good enough.
This is done by implementing new options `--help-scrubbed` and
`--help-scrubbed-full` and using these in our tests instead of `--help` and
`--help-full` (which remain unaffected).
Also don't wrap the default values in `$(i,...)` anymore because the defaults
can trigger line breaks and then the man page is ill-formatted because that
format is stupid.

Replaced by pulse. `--ownership` is now a deprecated form of `--pulse`.
The ownership checker is starting to give wrong answers due to changes in the

Summary:
This is a simple checker that identifies inefficient uses of `keySet` iterator where (not only the key but also) the value is accessed via `get(key)`. It is more efficient to use `entrySet` iterator which already returns both key-value pairs. This optimization would get rid of many extra lookups which can be expensive.
We simply traverse the CFG starting from the loop head upwards and pick up the map that is iterated over. Then, we check in the loop nodes if there is a call to `get(...)` over this map. If, so we report.

Summary:
`make clean` would fail calling `xcodebuild` to clean. It also calls `ant
clean`. Instead, do the cleaning ourselves by deleting the appropriate stuff so
that it's faster and more reliable.
Also clean the OCaml build before cleaning the tests as that's what more
important most of the time.
Also don't delete the man pages as part of `make clean` as they are checked in.
Also fix ant's Makefile so that the build points at the right .class files (the
path to the .class files was wrong so `make -C infer/tests/build_systems/ant`
would start `ant` for *each* file instead of once).

Summary:
Switches from opam 1 to opam 2.
Opam2 has some cool new features that simplify some of the scripting.
Notable changes:
1. Use the new `opam lock` *plugin* from https://github.com/AltGr/opam-lock/ instead of https://github.com/rgrinberg/opam-lock. This has a simpler interface for our purposes.
2. Change the way `./build-infer.sh` can be called to use an already existing switch: simply pass `--user-opam-switch` to the script and it won't attempt to create/set the current switch. This can be used to build infer in a local switch for instance.
3. Take advantage of automatic pinning where possible, eg to install infer deps without using opam.locked.

Summary:
New analysis in foetal form to detect invalid use of C++ objects after their
lifetime has ended. For now it has:
- A domain consisting of a graph of abstract locations representing the heap, a map from program variables to abstract locations representing the stack, and a set of locations known to be invalid (their lifetime has ended)
- The heap graph is unfolded lazily when we resolve accesses to the heap down to an abstract location. When we traverse a memory location we check that it's not known to be invalid.
- A simple transfer function reads and updates the stack and heap in a rudimentary way for now
- C++ `delete` is modeled as adding the location that its argument resolves to to the set of invalid locations
- Also, the domain has a really crappy join and widening for now (see comments in the code)
With this we already pass most of the "use after delete" tests from the
Ownership checker. The ones we don't pass are only because we are missing
models.
