- * A refcounting scheme that supports circular refs. It accomplishes this by
- * partitioning the set of objects into groups such that no cycle spans groups;
- * we can then reference-count the group as a whole and ignore refs within the
- * group. When objects are mutable, these groups are computed very
- * conservatively; we group any objects that have ever had a link between them.
- * When objects are frozen, we compute strongly-connected components which
- * allows us to be precise and only group objects that are actually cyclic.

- * This header is INTERNAL-ONLY! Its interfaces are not public or stable!
- * This file defines very fast int->upb_value (inttable) and string->upb_value
- * (strtable) hash tables.
- *
- * The table uses chained scatter with Brent's variation (inspired by the Lua
- * implementation of hash tables). The hash function for strings is Austin
- * Appleby's "MurmurHash."
- *
- * The inttable uses uintptr_t as its key, which guarantees it can be used to
- * store pointers or integers of at least 32 bits (upb isn't really useful on
- * systems where sizeof(void*) < 4).
- *
- * The table must be homogenous (all values of the same type). In debug
- * mode, we check this on insert and lookup.

- * A upb_handlers is like a virtual table for a upb_msgdef. Each field of the
- * message can have associated functions that will be called when we are
- * parsing or visiting a stream of data. This is similar to how handlers work
- * in SAX (the Simple API for XML).
- *
- * The handlers have no idea where the data is coming from, so a single set of
- * handlers could be used with two completely different data sources (for
- * example, a parser and a visitor over in-memory objects). This decoupling is
- * the most important feature of upb, because it allows parsers and serializers
- * to be highly reusable.
- *
- * This is a mixed C/C++ interface that offers a full API to both languages.
- * See the top-level README for more information.

- // TODO(haberman): right now all of these functions take selectors. Should they
- // take selectorbase instead?
- //
- // ie. instead of calling:
- // sink->StartString(FOO_FIELD_START_STRING, ...)
- // a selector base would let you say:
- // sink->StartString(FOO_FIELD, ...)
- //
- // This would make call sites a little nicer and require emitting fewer selector
- // definitions in .h files.
- //
- // But the current scheme has the benefit that you can retrieve a function
- // pointer for any handler with handlers->GetHandler(selector), without having
- // to have a separate GetHandler() function for each handler type. The JIT
- // compiler uses this. To accommodate we'd have to expose a separate
- // GetHandler() for every handler type.
- //
- // Also to ponder: selectors right now are independent of a specific Handlers
- // instance. In other words, they allocate a number to every possible handler
- // that *could* be registered, without knowing anything about what handlers
- // *are* registered. That means that using selectors as table offsets prohibits
- // us from compacting the handler table at Freeze() time. If the table is very
- // sparse, this could be wasteful.
- //
- // Having another selector-like thing that is specific to a Handlers instance
- // would allow this compacting, but then it would be impossible to write code
- // ahead-of-time that can be bound to any Handlers instance at runtime. For
- // example, a .proto file parser written as straight C will not know what
- // Handlers it will be bound to, so when it calls sink->StartString() what
- // selector will it pass? It needs a selector like we have today, that is
