There are two recent changes in zig that effect awshttp.
1. cf65ab8 disallows unused variables. Fair enough and backward
compatible.
2. https://github.com/ziglang/zig/issues/2115#issuecomment-827968279
This comment resulted in a backward incompatible change to use the
underlying value from a C enum rather than its symbol. This reduces
edge cases in the compiler. Ultimately we may want awshttp to define
zig enums that mirror the C enums, but for now I've commented the
definitions of the C enums used.
There appears to be a leak in json.zig, which had minimal modifications for
snake/camel case, including use of an allocator. It is not obvious that
the leaks were added by these changes, so I will leave this issue for
later investigation.
This should complete the query protocol calls. However, there are likely
gaps in implementation for the transformation of request parameters
to url encoded body data
This seems silly, but I guess in AWS it is a thing that these two values may
be different. Consumers of awshttp have the option of ignoring this, which
should be correct most of the time. Aws.zig will, however, use the service
metadata to do the right thing
