2020-11-12Relax nullability annotation on allocation functionsDavid Robillard1-3/+5
In practice almost nobody checks for failed allocation, including unfortunately the serd tests and serdi itself. Adding a struct mode to conditionally define this would be a good idea to support allocation-hardened code, but for now just mark them as unspecified instead. On the bright side, this documents the nature of the returned pointers nicely.
2020-11-11Add nonnull and nullable attributes to APIDavid Robillard1-183/+214
This will warn if NULL is passed to any nonnull-annotated parameter, and is also supported by sanitizers which can check for violations at runtime. Unfortunately, it is currently only supported by clang. GCC has a similar feature in the nonnull attribute, but this has a different syntax (it's a function attribute) and is more dangerous since it is used by the optimizer to assume a null pointer is undefined behavior. This one just warns and still allows code to handle the situation gracefully, which I think is more appropriate for a library API. Note that this optimization behavior is not some unlikely edge case: switching these attributes to the GCC one will break release builds.

2020-11-09Fix clang-tidy hicpp-signed-bitwise warnings in headerDavid Robillard1-15/+15
In exchange for suppressing a pointless superficial warning instead, but I dislike that convention since it looks confusing when hex digits are used and it's inconsistent with near-universal floating point suffix convention.
