Checklist
Doxygen
(bullet points are in order of appearance)
- First line explains briefly what the function does
- first entry in meta-information
- Simple example or snippet how to use the function
- Longer description of function containing common use cases
- Description of functions reads nicely
- Use it -> Use this function
- So you want -> Afterwards, when you want to iterate the meta-information, you have
@pre
- add 'key must be a valid key'
@post
- add 'internal iterator set to first entry in metadata'
@param
for every parameter
- key: Key whose internal iterator should be rewinded
@return
/ @retval
- move success to normal
@return
@ingroup
@see
- split first line into two
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
- All possible error states are covered by tests
- add test for null pointer
- All possible enum values are covered by tests
- No inconsistencies between tests and documentation
