@zvictorino thanks for opening this PR! Tests are failing because there is a missing package, you will need to add it with |
let's name the setting The setting will also need some docs. Almost all symbols are private to the package, don't export them. |

this calls for an enum like type (over string):
type saslMechanism string
const (
saslTypePlaintext = sarama.SASLTypePlaintext
...
)
func (m *saslMechanism) Unpack(in string) error {
in = strings.ToUpper(in) // try not to force users to use all upper case
switch in {
case saslTypePlaintext, ...:
*m = saslMechanism(in)
default:
return fmt.Errorf("not valid mechanism '%v', only supported with PLAIN|SCRAM-SHA-512|SCRAM-SHA-256", in)
}
return nil
}
The unpack method will be called by (*Config).Unpack
. If it fails the full config name and the config file the setting comes from will be reported.
There is another 'string' comparison in order to fill in the sarama SASL settings. Having magic strings in different places is a good way to introduce Bugs (future developer might have typo when adding another mechanism). Better use an enum and use contanstants (compiler will complain if there is a typo). By having our own type we can also do this (optional):
func (m saslMechanism) configureSarama(... <other input>?, config *sarama.Config) error {
switch m {
case saslScramSHA256:
...
case sasl<type>:
...
default:
panic(<we shouldn't get here, assuming no developer messed up>)
}
}
Hi @zvictorino, we have found your signature in our records, but it seems like you have signed with a different e-mail than the one used in your Git commit. Can you please add both of these e-mails into your Github profile (they can be hidden), so we can match your e-mails to your Github profile? |
Move some codes to separate file.

Hello @zvictorino this is a really nice addition, its there anything we could help to move it forward with you? |
jenkins, test this |
can anyone merge this pull request plz ? |
@zvictorino there is a merge conflict, could you please update the branch with master? Thanks! |
💚 CLA has been signed |
Update code to master
ok to test |
jenkins, test this again please |
Code LGTM, but there would be some pending things. We would need a changelog entry, docs for the new options, and some tests. @zvictorino let me know if you can continue with this, if not I am ok with merging this as is and create an issue with some follow up tasks. Thanks! |
