d_rocket_lints 2.0.0

Analyzer plugin rules for the d_rocket framework: detects closure LINQ calls (which run in-memory only and should be rewritten with Expr.lambda for SQL translation) and N+1 navigation fetches in loops.

2.0.0 — 2026-06-22

Breaking

• Plugin host migration: switched from the archived custom_lint_builder 0.8.x (max analyzer 8.0.0) to the official analysis_server_plugin 0.3.x from tools.dart.dev. analyzer is bumped from ^8.4.0 to ^10.0.1. This is the minimum to be on the same analyzer major as d_rocket_builder 2.0.0.
• SDK floor: sdk: ^3.9.0 (was ^3.4.0).
• Discovery: the analyzer.plugins: [d_rocket_lints] block in analysis_options.yaml replaces the old custom_lint: block. The two are mutually exclusive.
• Rule class names: the rule classes stayed in src/lints/ (no rename). The typedefs LinqClosureLint / NPlusOneLint (1.x names) are preserved for source compatibility. If you were importing the top-level linq_closure_lint.dart or n_plus_one_lint.dart files (only relevant for plugin host testing), no import change is needed.

Added

• 2 active rules at GA:
  • LinqClosureRule — detects dbSet.where_(b => b.x == 1) style LINQ predicates that evaluate in-memory only and offers a dart fix suggestion to wrap the closure in Expr.lambda(...) for SQL translation.
  • NPlusOneRule — detects for loops over dbSet.where_(...).toList() that trigger an N+1 navigation fetch (one query per row, instead of one IN (...) query).
• Golden test fixtures in test/goldens/ for both rules (positive + negative cases).
• dart fix support for LinqClosureRule.

Removed (from 1.x)

• The lint_rule_test.dart dart fix golden file for LinqClosureRule (the rule was promoted out of beta and the fix file was renamed for clarity).
• pub_workspace.dart test helper (was specific to the custom_lint_builder host and is no longer applicable).
