Signature
Key *keyDup(const Key *source)
Checklist
Doxygen
(bullet points are in order of appearance)
- First line explains briefly what the function does
- could be a bit more specific
- Simple example or snippet how to use the function
- remove the wrapping function as it only distracts
- Longer description of function containing common use cases
- Description of functions reads nicely
- "Like for a new key" could be formulated better
@pre
- Precondition
- source must be a valid key
@post
- Postcondition
- returns a full copy of the key including all info (metadata, ..)
@invariant
- Invariant
- source stays a valid key
@param
for every parameter
Naming
- Abbreviations used in function names must be defined in the Glossary
- Function names should neither be too long, nor too short
- Function name should be clear and unambiguous
- Abbreviations used in parameter names must be defined in the Glossary
- Parameter names should neither be too long, nor too short
- Parameter names should be clear and unambiguous
Compatibility
(only in PRs)
- Symbol versioning is correct for breaking changes
- ABI/API changes are forward-compatible (breaking backwards-compatibility to add additional symbols is fine)
Parameter & Return Types
- Function parameters should use enum types instead of boolean types wherever sensible
- Wherever possible, function parameters should be
const
- Wherever possible, return types should be
const
- Functions should have the least amount of parameters feasible
Structural Clarity
- Functions should do exactly one thing
- Function name has the appropriate prefix
- Order of signatures in kdb.h.in is the same as Doxygen
- No functions with similar purpose exist
Memory Management
- Memory Management should be handled by the function wherever possible
Extensibility
- Function is easily extensible, e.g., with flags
- Documentation does not impose limits, that would hinder further extensions
Tests
- Function code is fully covered by tests
- Error state is hard to check, cause it only appears on null pointers which gets checked in the function itself already
- All possible error states are covered by tests
- All possible enum values are covered by tests
- No inconsistencies between tests and documentation
