Description
  • Tiki lets us configure min_username_length and max_username_length unless we select login_is_email
  • If we select login_is_email, these configs are hidden but max_username_length is still enforced in lib/validators/validator_username.php and in lib/registration/registrationlib.php


The database structure seems to let us have as many as 191 chars without an issue. Certainly these are actually bytes, not chars.
Notes: If we use english logins or emails as logins, it's 191 characters. Accentuated chars in french and other european languages use 2 bytes (éààê). Some other languages use alphabets in which all chars use 2, 3 or 4 bytes.

My suggestion :

  • Important: We should not enforce min_username_length and max_username_length when preference login_is_email is selected.
  • Nice to have: We should still have some hard limit of 191 bytes (not chars) even if login_is_email is selected (needs to be tested with utf8 characters) so that people get a nice explanation instead of a mysql error message about an insert failure.

Keywords

The following is a list of keywords that should serve as hubs for navigation within the Tiki development and should correspond to documentation keywords.

Each feature in Tiki has a wiki page which regroups all the bugs, requests for enhancements, etc. It is somewhat a form of wiki-based project management. You can also express your interest in a feature by adding it to your profile. You can also try out the Dynamic filter.
