libCalligraDB

Minutes from IRC meeting

  • 2012-07-03
  • requested by jstaniek
  • attended by boemann, jstaniek, smitpatel
  • idea: storage for bibliography could re-use libKexiDB instead of libQtSQL
  • pros:
    • simplify the code
    • increase code re-use - KexiDB is developed 8+ years already with reuse in mind
    • make the database ($HOME/.calligra/biblio.sqlite) accesible to Kexi, so biblio db can be added to the Kexi Scientific templates for data re-use and manipulation
    • KexiDB has database and table creation API, QtSQL does not (code complexity)
  • cons and questions:
    • size of libKexiDB as dependency (Biblio already uses SQLite3, which is the biggest dependency compared to either QtSQL or KexiDB)
    • we're moving to predicate (but that would happen no earlier than in 3.0, realistically in 3.1 or 3.2), so KexiDB is here for the transition
    • are the APIs stable? (yes, most changes happen in Predicate, moreover KexiDB is calligra's internal API, so will be updated with the apps and the Biblio code)
    • Words cannot depend on Kexi (it wouldn't, relevant parts of KexiDB should be moved to calligra/libs/)
  • extra points, from Kexi's perspective
    • Kexi will have biblio-feature db in 3.x anyway as a template, which ideally would depend on Words too. With kexidb reuse we would avoid incompatible two databases, extra work, and two Biblio products.
    • For now Kexi lacks templates that are real world and integrated with other Calligra apps.
  • current state: smitpatel delivered QtSQL-based code for Biblio (within GSoC 2012)
  • final agreement has been reached
  • KexiDB adoption
  • Biblio can be still kept small enough
  • jstaniek offers to move relevant part of KexiDB to calligra/libs/
    • the library renames to calligradb and the dir is calligra/libs/db/ (to avoid references to Kexi)
  • jstaniek offers support for smitpatel in development
  • jstaniek offers support for porting when Predicate arrives
  • jstaniek offers maintaining the libcalligradb for Qt 5.0
  • jstaniek proposes to keep KexiDB namespace in libcalligradb however since it defines API which is heavily used in Kexi (3200+ times); after moving to Predicate it won't be a problem
