This patch addresses the circular dependency issues and code quality
concerns identified in QA by introducing a clean architectural solution.
Changes:
1. Created Koha::Plugins::Loader - A lightweight plugin loader with
minimal dependencies that can be safely called during early
initialization. Uses DBIx::Class when available for proper
transaction support, falls back to raw DBI for early init.
2. Added Koha::Database::table_exists() - Consolidated table checking
logic into a reusable method that can be called as both class and
instance method.
3. Simplified C4::Context BEGIN block - Reduced from ~120 lines to
~13 lines (91% reduction). Removed XML::Simple dependency and
manual database connection code.
4. Updated Koha::Plugins::get_enabled_plugins() - Now delegates to
the Loader module for consistency.
5. Updated C4::Installer::TableExists - Delegates to the new
Koha::Database::table_exists method.
This addresses all QA concerns:
- Eliminates XML::Simple usage (David Cook)
- Uses Koha::Database instead of manual DBI (David Cook)
- Reuses table checking logic (Nick Clemens)
- Eliminates circular dependencies (Paul Derscheid)
- Much cleaner and maintainable code
Test plan:
1. Run tests:
prove t/db_dependent/Koha/Database.t
prove t/db_dependent/Koha/Plugins/Loader.t
prove t/db_dependent/Koha/Plugins/Plugins.t
2. All tests should pass
3. Install and enable a plugin via the UI
4. Verify plugin hooks are called correctly
5. Verify no regressions in plugin functionality
