[nullsafe][refactor tests] split and improve FieldNotNullable tests Summary: 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.

[nullsafe] When inferring type based on the formal type, respect NullsafeType instead of reading annotations Summary: This continues work for eliminating Annot.Item.t from Nullsafe low-level code. The introduced function `from_nullsafe_type` is called when we infer initial type of the equation based on the function or field formal signature. Before that, we did it via reading the annotation directly, which complicates the logic and making introducing Unknown nullability tricky. ## Clarifying the semantics of PropagatesNullable This diff also clarifies (and changes) the behavior of PropagatesNullable params. Previously, if the return value of a function that has PropagatesNullable params was annotated as Nullable, nullsafe was effectively ignoring PropagatesNullable effect. This is especially bad because one can add Nullable annotation based on the logic "if the function can return `null`, it should be annotated with Nullable`. In the new design, there is no possibility for such a misuse: the code that applies the rule "any param is PropagatesNullable hence the return value is nullable even if not explicitly annotated" lives in NullsafeType.ml, so this will be automatically taken into account. Meaning that now we implicitly deduce Nullable annotation for the return value, and providing it explicitly as an alternative that does not change the effect. In the future, we might consider annotating the return value with `Nullable` explicit. Reviewed By: jvillard Differential Revision: D17479157 fbshipit-source-id: 66c2c8777

[nullsafe] Prepare to introduce gradual mode: split tests 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.

[nullsafe] Prepare to introduce gradual mode: split tests 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.

[nullsafe] Prepare to introduce gradual mode: split tests 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.

[nullsafe] Introduce Strict mode Summary: This is the first take on strict mode semantics. The main invariant of strict mode is the following: If the function passes `NullsafeStrict` check and its return value is NOT annotated as Nullable, then the function does not indeed return nulls, subject to unsoundness issues (which should either be fixed, or should rarely happen in practice). This invariant helps the caller in two ways: 1. Dangerous usages of non strict functions are visible, so the caller is enforced to check them (via assertions or conditions), or strictify them. 2. When the function is strict, the caller does not need to worry about being defensive. Biggest known issues so far: 1. Condition redundant and over-annotated warnings don't fully respect strict mode, and this leads to stupid false positives. (There is so much more stupid false positives in condition redundant anyway, so not particularly a big deal for now). 2. Error reporting is not specific to mode. (E.g. we don't distinct real nullables and non-trusted non-nulls, which can be misleading). To be improved as a follow up.
