-------------------------------------
Summary: More consistent/strict validation of role names please
Key: MESOS-7734
URL: https://issues.apache.org/jira/browse/MESOS-7734
Project: Mesos
Issue Type: Improvement
Reporter: James DeFelice
As per the currently implemented role validation rules:
https://github.com/apache/mesos/blob/63e08146aa7aa8efac3928922b6cdef92aa1d2ce/src/common/roles.cpp#L71
... the following role names are allowed:
{code}
eng-
eng*
*eng
eng.
eng..
...
..eng
{code}
The `/` character has good validation semantics around it and it's a much less
confusing character to use when composing hierarchical role names. The `*`,
`.`, and `-` characters have specific validation rules within narrow context,
but it's too easy for someone to compose confusing role names using these
characters.
IMO, validation should severely restrict the context in which the `*` and `.`
characters are used, as well as implement a symmetrical "endWith" check for `-`
characters.
