Array members are currently being named "TODO" (whoops). Include arrays in
TopoSorter so each one can have a `NameProvider` generated in CodeGen. Then
pass array elements through `make_field`.
Test plan:
- CI
- Add array member names to an array test.
`std::list` has per element overhead for the individual heap allocations. This
was already calculated in the container implementation but not used. Allocate
the overhead of each element in the `std::list` to the `std::list` itself as
with other sequential containers.
Test Plan:
- CI
- Updated test cases
This test is a bit odd, but this change adds the full set of size/member checks
for the hierarchy for TreeBuilder v2 and enables it.
Closes#304

Type names of optional elements were accidentally left as todo. Update
`std::optional` to use `make_field` and correctly name its elements.
Test Plan:
- CI
- Updated the integration tests to test the names.
Summary:
We have a good type representation in the Type Graph of an incomplete type and
the underlying type that represents. However, this incomplete type still ends
up in the generated code as `void` which loses information. For example, a
container that can't contain void may fail to compile because it was
initialised with `void` but really its because the type it was supposed to be
initialised with (say, `Foo`) had incomplete debug information.
This change identifies that a type is incomplete in the output by generating it
as an incomplete type `struct Incomplete<struct Foo>`. This allows us to name
the type correctly in the TreeBuilder output and filter for incomplete types,
as well as getting appropriate compiler errors if it mustn't be incomplete.
Test Plan:
- CI
- Added a unit test to namegen.
- Enabled and added an extra pointers_incomplete test.
This change is tricky to test because it isn't really user visible. The types
still use their `inputName` which is unchanged in any successful output - this
change is used so the compiler fails with a more detailed error.
Add the option to calculate total size (inclusive size) by wrapping the
existing iterator. This change provides a new iterator, `SizedIterator`, which
wraps an existing iterator and adds a new field `size` to the output element.
This is achieved with a two pass algorithm on the existing iterator:
1. Gather metadata for each element. This includes the total size up until that
element and the range of elements that should be included in the size.
2. Return the result from the underlying iterator with the additional
field.
This algorithm is `O(N)` time on the number of elements in the iterator and
`O(N)` time, storing 16 bytes per element. This isn't super expensive but is a
lot more than the current algorithm which requires close to constant space.
Because of this I've implemented it as a wrapper on the iterator rather than on
by default, though it is now on in every one of our integration test cases.
Test plan:
- Added to the integration tests for full coverage.
Summary:
Remove the now useless `handler` and adds the `traversal_func` and `processor`
entries for `std::list`. This type is a bit weird as most of our sequential
containers don't have any overhead on storing the element. I went for the same
approach we take for maps where we have a shared `[]` element covering the map
overhead and below that a `key` & `value`. As we only have a single element
under it which doesn't have a logical name I went for `*`.
Closes#315.
Test Plan:
- CI
- Copied the relevant `std::vector` tests and updated the existing one.
Summary:
Currently there are two features between CodeGen v2 (TypeGraph) and TreeBuilder
v2. These are TypedDataSegment and TreeBuilderTypeChecking. Each of these
features currently has a full set of tests run in the CI and each have specific
exclusions.
Collapse these features into TreeBuilder v2. This allows for significantly
simplified testing as any OIL tests run under TreeBuilder v2 and any OID tests
run under TreeBuilder v1.
The reasoning behind this is I no longer intend to partially roll out this
feature. Full TreeBuilder v2 applies different conditions to containers than
the intermediate states, and writing these only to have them never deployed is
a waste of time.
Test Plan:
- it builds
- CI
Summary:
Adds the option for required features to container definitions. These cause the container not to be passed to `DrgnParser` if that feature is not enabled during code generation. The thrift isset type does not currently work with `tree-builder-v2` and only provides benefit with `capture-thrift-isset`. This change makes sure the container is ignored if it won't be useful, allowing code generation under `tree-builder-v2`.

Summary:
Previously OID/OIL required exactly one configuration file. This change makes it so you can supply 0 or more configuration files. 0 is useful if you have pre-generated the cache or use some sort of remote generation system. 1 is useful for the common case, where you have a configuration file that describes your entire source and use just that. More are useful if you have supplemental bits of config you wish to apply/override - see the changes to the integration test framework where we do exactly this.
Test Plan:
This isn't super well tested. It works for the test cases which add features via the config or enable `codegen.ignore`.

Summary:
Update to clang-15 compiler and libraries as clang-12 is ancient.
The changes to oilgen are necessary because the new internal toolchain is being more picky about linking PIC to PIC. In certain modes we build with PIC, but try to link a non-PIC oilgen artifact. Add the ability to build the oilgen artifacts with PIC which sorts this.
