Ensure Robust Filenames

[tbsbdr]

Description

User Stories

• As a user, I prefer not to be responsible for typing compatible filenames to ensures that files are reliably synced for other users on every client.

Value

• robustness
• reliability

Acceptance Criteria

• Forbidden Characters: provide a config option to define forbidden characters for resource names, defaults are:
  • < (less than)
  • > (greater than)
  • : (colon)
  • " (double quote)
  • / (forward slash)
  • \ (backslash)
  • | (vertical bar or pipe)
  • ? (question mark)
  • * (asterisk)
• Max Math lengths: provide a config option to define the maximum path length for resources, default is:
  • 260 chars
• Case Sensitivity: provide a config option to define if resource names are case sensitive, default is:
  • No Case sensitivity (test.txt and Test.txt are the same as you can see)
• Frobidden pattern:
  • Do not end a resource name with a space or a period.
• resources that do not comply with the rules above can not be created.
• announce these rules to the clients so that the clients can provide helpful guidance for naming conventions for the enduser (validation messages in the ui)
• Maybe add a comment to the config that ocis is per se a superior application that would work without these rules and defaults to these rules only for compatibility reasons mainly because of legacy systems like Windows

Definition of ready

• [ ] Everybody needs to understand the value written in the user story
• [ ] Acceptance criteria have to be defined
• [ ] All dependencies of the user story need to be identified
• [ ] Feature should be seen from an end user perspective
• [ ] Story has to be estimated
• [ ] Story points need to be less than 20

Definition of done

• Functional requirements
  • [ ] Functionality described in the user story works
  • [ ] Acceptance criteria are fulfilled
• Quality
  • [ ] Code review happened
  • [ ] CI is green (that includes new and existing automated tests)
  • [ ] Critical code received unit tests by the developer
• Non-functional requirements
  • [ ] No sonar cloud issues
• Configuration changes
  • [ ] The next branch of the ocis charts is compatible

Max Math lengths: provide a config option to define the maximum path length for resources, default is: 260 chars

It is incorrect to measure in characters (for ext2, ext3, ext4, zfs). We should measure in bytes because we allow the UTF-8 in a file name.
