Summary:
It adds typ field in Sil.Store. The field will be used by the analyzer in the following diffs.
Motivation: Interbo generates a symbolic value when evaluating expressions including parameter symbols. At that time, it is done with depending on their types, e.g., an integer, a pointer to struct or a pointer to array. Without the type, it is hard to generate a correct symbolic value that will be instantiated later in call sites. Thus, evaluating RHS of the store statement, the type of RHS is better to be given.

See motivation below.
This diff is dealing with FieldNotNullable:
- move not relevant subclasses into dedicated classes and files
- modify the tests so they comply with the standards below
--Motivation--
Gradual mode we are going to introduce is an invasive change in how Infer
treats nullability semantics.
In order to make the change in a controllable way, we need the tests to comply with the
following standards and conventions.
1. For each code peace where we expect a bug to happen, the there should be
corresponding (minimally different from above) peace of code where we expect a bug to NOT happen. (This is to ensure bug is happening for exact reason we think it is happening).
2. Conversely: for each peace of code where we expect a bug to be NOT
present, there shuold be a peace of code where the bug IS happening.
(Otherwise there can be too many reasons for a bug NOT to happen).
3. Convention: end corresponding methods IsOK and IsBUG correspondingly.
4. Keep code examples as small as possible.

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.

Summary:
This abstraction was not always used consistently.
Its usage made more sense when it supported both present annotations and
optional annotation (which got removed in previous diff).
The rought semantic of that was "what is the inferred type for such and
such value (variable or expression) in typestate". So it is not really
_annotation_ in first place, it is more like "what we inferred about
nullability given annotations, known special cases, and current sybmolic
execition state".
Let's explicitly rename `map` to `is_nullable`. If/when we need to
enhance this further (and we likely will), we will do it accordingly.

`Present` annotation was an experiment made many years ago that never
got into real usage. The idea was to annotate Optional<> types with
Present, which means that it is safe to call get().
We don't plan to support `Present` annotation for optional types in the
near future.
Support of `Present` annotation requires extra levels of abstraction
that make the changing the behavior and introducing new features harder.
A lot of checks for nullability are written in generic way so they also
check for presense.
Getting rid of that will allow us to simplify our
work for introducing new semantics for nullsafe.

Implementation of write-serializer for Sqlite. Points of note:
- A Unix socket is used for communication. This avoids buffer-size limitations, as the objects we send for writing may exceed said limits.
- No daemon is used if running under buck or in genrule mode, as this usually means a single-threaded job capturing into the DB.
- When the daemon is running, read-only access is *not* enforced for other processes. This makes starting and stopping the daemon during Infer execution easier and more robust. In WAL mode this should not have any effect on performance.
- This version is not economical with connections, it uses one per query, todo.

Summary:
Write contention is becoming a problem in parallel capture (eg when make runs with high parallelism) or when analysis writes CFGs to the DB in parallel (eg when analysing blocks in ObC). This is believed to lead to BUSY errors in Sqlite.
This is step 1 of a process where all writes are cordoned-off in one module, and fixing the interface for that module.

Summary:
When running with high parallelism and a large number of insertions in the DB (eg, ObjC analysis with block specialisation), we see MISUSE exceptions thrown by Sqlite **when trying to bind parameters to queries**. It does not always occur, and maybe that's because the check in Sqlite that throws this error is documented as "probabilistic". For the same reason, it is plausible that high parallelism increases the chance of detection.
According to documentation this unequivocally means a bug in our usage of the API (https://www.sqlite.org/rescode.html#misuse), in particular that a parameter is re-bound while the query is running (https://www2.sqlite.org/cvstrac/wiki?p=LibraryRoutineCalledOutOfSequence). I believe this may have to do with `result_fold_rows` (as it's the only one that uses a query that can be continued, and thus misused), but I have not managed to track the bug.
Always resetting the query before using it is a defensive measure that seems to make these errors go away (and turn some of them to BUSY timeouts, which should be addressed by a write serialiser, but in any case it's a more logical state of affairs = higher parallelism means more contention thus possibly timeouts due to lock usage).

Intuitively, I expect (and I think majority of users would expect) that
`--debug` makes things more verbose (and potentially more slow / consuming
more memory and disk space), but does not change anything apart from it.
One pro of preserving existing behavior, pointed by jvillard:
- Suppose some check is experimental or disabled in the config. The
users expect the issue to be found, but it does not show up. They run
`infer --debug` to understand the behavior, and suddenly the issue shows
up.
I, hovewer, find this pro not important enough and potentially confusing
the users even more.
(If they want to investigate seriously, they can always use
--no-filtering, and there are a lot of cases when the issue does not
show up for others, much hard to undertand reasons, than the fact that

`nullsafe` currently allows the following:
```
public void Nonnull Object willBeOK() { return null; }
```
But disallows the following:
```
public void Object willBeAnIssue() { return null; }
```
This was a deliberate choice made back in 2014.
The motivation was to provide a way to tell the checker "I know it can not be null, trust me".
A huge problem with that approach is that it is extremely non-intuitive and surprising, and contradicts with pretty much everything when Nonnull or similar annotations are used in external world.
This is not the way how checkers should be supressed.
We do provide 2 options to express this intention, namely `assertNotNull` and `assumeNotNull` would do the thing.
This is a much better approach for additional reason: assertNotNull is
granular and applies only to the exact expression that is under
question. In contrast, suppressing the check on the whole function level
make any modifications of a function dangerous.

- Replacing `AccessExpression` for `AccessPath` and removing conversions from the former to the latter except in:
- Printing functions, to ensure formatting issues won't change tests/CI.
- Reporting/deduplication still happens through access path conversion, as we need an analogue of `ModuloThis` for `AccessExpression`.

Change the logic of the annotation reachability checker in the following
ways:
1. Sanitizers take priority over sinks, i.e. a procedure that is both a
sink and a sanitizer is not a sink. This changes the existing tests
that seemed to assume the opposite. However I think that way is more
useful and goes better with the fact that sanitizers are specified as
"overrides".
2. When applying a summary, check again that we are not in a sanitizer
for the corresponding sink.
Without (2) this there was a subtle bug when several rules were
specified. For example, if `sink_wrapper()` wraps `sink()` for a rule
`R` then the summary of `sink_wrapper()` will be: `R-sink : call to sink()`.
Then, suppose `sanitizer()` calls `sink_wrapper()` and `sanitizer()` is
a sanitizer for `R` but not for another rule `R'`. The previous code
would add the call to `sink()` to the summary of `sanitizer()` because
it's not a sanitizer for `R'`, even though `sink()` is not a sink for
`R'`!
The current code will re-apply the rules correctly so that sinks are
matched only against the right sanitizers.

Summary:
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.
