ORE Operators and Sorting
Use same drop setup on install and uninstall
This change reverts this repo back to 01dcc24. The changes reverted include commits from: - #86 - #87 We mostly want to revert the changes in #86 (since they aren't working as intended with Proxy), but #87 is also included since it's more recent (and also includes some ORE-related changes that would be tedious to untangle). Since there aren't many changes after #86, the most pragmatic option is to revert to the last known-good state and redo the install/uninstall changes by hand on top of that. Commands used to revert: ``` git reset --hard 01dcc24 git reset --soft ed460fc ``` This change doesn't use `git revert` because there were > 20 commits to revert and merge commits also don't play well with `git revert`.
Revert back to commit 01dcc24
This change updates `cs_ore_64_8_v1` to parse ORE indexes (the `'o'` field) as JSON arrays of hex-encoded strings (instead of casting from the Postgres text format). The corresponding change for encoding ORE indexes as JSON arrays of hex-encoded stings has already been merged in Proxy. This is similar to some of the changes in #86, but we're parsing into the composite types for ORE indexes instead of into a plain `bytea[]`. Parsing into the composite type allows for ordering with an operator class on the output from `cs_ore_64_8_v1`.

Address code review recommendations to improve documentation accuracy
and add safety warnings for DDL-executing functions.
**Documentation Improvements:**
1. **src/encryptindex/functions.sql:102-103** - Clarified select_target_columns
- Enhanced note to explain full JOIN logic (checks both column_name
and column_name_encrypted with type verification)
- Previous: "LEFT JOIN returns NULL when no match"
- Updated: Explains both name matching variants and type requirement
2. **src/jsonb/functions.sql:296** - Enhanced jsonb_array_length exception
- More specific @throws documentation with exact error message
- Previous: "if value is not an array (missing 'a' flag)"
- Updated: "'cannot get array length of a non-array' if 'a' flag
is missing or not true"
3. **src/jsonb/functions.sql:29** - Clarified NULL handling in jsonb_path_query
- Precise SETOF return semantics
- Previous: "Returns NULL if val is NULL"
- Updated: "Returns a set containing NULL if val is NULL"
**Safety Warnings:**
4. **src/encryptindex/functions.sql:152** - Added @warning to create_encrypted_columns
- Highlights dynamic DDL execution (ALTER TABLE ADD COLUMN)
- Alerts users to schema modification side effects
5. **src/encryptindex/functions.sql:180** - Added @warning to rename_encrypted_columns
- Highlights dynamic DDL execution (ALTER TABLE RENAME COLUMN)
- Alerts users to schema modification side effects
**Quality Assurance:**
- ✅ All tests passing (59 test files)
- ✅ Code review approved (CODE_REVIEW_PHASE_4_COMPLETE.md)
- ✅ 0 blocking issues
- ✅ All NON-BLOCKING recommendations addressed
**Note:** User fixed blocking code bug in jsonb_path_query_first separately
…ed_with_active_config **Problem:** Documentation incorrectly stated that the 'v' field stores the active configuration ID, contradicting src/encrypted/constraints.sql:56 which correctly documents that 'v' must be the literal payload version "2". **Root Cause:** The 'v' field serves a single, consistent purpose across the entire codebase: it stores the EQL payload format version (currently "2"). It does NOT store configuration IDs. **Fix:** - Removed incorrect claim that 'v' stores configuration ID - Clarified that 'v' field stores payload version "2" - Updated function description to avoid implementation details - Added note explaining the distinction **Files Changed:** - src/encryptindex/functions.sql:201-209 **Verification:** - ✅ All tests passing (59 test files) - ✅ Documentation now consistent with src/encrypted/constraints.sql:56 - ✅ No code changes - documentation-only fix **Context:** This addresses feedback about major documentation inconsistency where two different files made contradictory claims about the 'v' field's purpose. The payload version is always "2" for EQL v2, as enforced by the _encrypted_check_v validation function.
Document version.template (source of auto-generated version.sql): - @file and @brief for template purpose - Full documentation for eql_v2.version() function - @note explaining template and build-time replacement - @example showing usage This achieves 100% documentation coverage (53/53 files) by documenting the source template rather than the generated file. The documentation will be preserved through build process.
- Updated version.template to avoid awkward $RELEASE_VERSION text replacement in docs - Changed @file tag from version.template to version.sql (the generated file) - Simplified documentation to avoid version string in prose - Added comment in build.sh clarifying Doxygen comment preservation - Added validation scripts for documentation quality assurance: - check-doc-coverage.sh: Reports documentation coverage (100%) - validate-documented-sql.sh: Validates SQL syntax - validate-required-tags.sh: Checks for required @brief, @param, @return tags The sed command in build.sh already preserves all Doxygen comments from the template, ensuring the generated version.sql is fully documented.
- Document required and optional Doxygen tags - Provide comprehensive documentation example - Reference validation tools for quality assurance - Add note about template file documentation - Update development notes to reference new standards This establishes clear documentation guidelines for all SQL functions and types in the EQL codebase.
- Create comprehensive Doxyfile for API documentation generation - Configure for SQL file parsing (treated as C++ for Doxygen) - Enable HTML output to docs/api directory - Exclude test files and build artifacts - Add docs/api/ to .gitignore for generated documentation To generate documentation: doxygen Doxyfile Output will be in docs/api/html/index.html
- Document how to generate API documentation with Doxygen - Explain documentation standards and required tags - Reference validation tools for quality assurance - Link to CLAUDE.md for contribution guidelines - Note automatic CI validation for PRs This makes documentation generation and standards visible to all users and contributors.
- Add docs:generate task to generate API documentation with Doxygen - Add docs:validate task to run coverage and tag validation - Document Doxygen installation via brew/apt in README - Update CLAUDE.md with new mise commands - Provide both mise and direct command usage examples Note: Doxygen is not available in mise registry, so must be installed separately via system package manager (brew, apt, etc.)
- Simplified Doxyfile to minimal working configuration - Added doxygen-filter.sh to convert SQL comments (--!) to C++ style (//!) - Set FILTER_SOURCE_FILES=YES to apply filter to all SQL files - Set EXTRACT_ALL=YES to extract all documented entities - Removed obsolete Doxygen tags causing warnings The key issue was that Doxygen's C++ parser cannot recognize SQL-style --! comments. The input filter is REQUIRED to convert them to //! which Doxygen understands. Tested: Generates 213 HTML files with full documentation content.
- Fix validate-required-tags.sh to use BSD-compatible sed instead of grep -P - Update GitHub workflow to use 'mise run docs:validate' instead of direct scripts - Update CLAUDE.md to recommend mise tasks as primary validation method - Maintain backward compatibility with direct script execution The grep -oP flag is a GNU extension not available in BSD grep (macOS). Replaced with sed pattern matching for cross-platform compatibility. CI now uses mise for consistency with local development workflow.
- Add missing @brief, @param, @return tags to operators - src/operators/~~.sql: Add function documentation for LIKE operator - src/operators/<>.sql: Add @param and @return tags - Fix validate-required-tags.sh to handle longer comment blocks - Increased tail from 20 to 100 lines to capture complete comments - Previous limit was truncating @brief tags in longer documentation blocks - Fixes false positive errors for well-documented functions All validation now passes with 0 errors and 0 warnings.
Combines: - Complete Phase 1-4 Doxygen documentation from continue-doxygen-sql-comments - Infrastructure from phase-4-doxygen: * Doxyfile configuration * Documentation validation scripts (check-doc-coverage.sh, validate-required-tags.sh) * CI integration updates * CLAUDE.md with Doxygen standards Resolution strategy: Kept documentation from continue-doxygen-sql-comments (has complete Phase 1-4 work + subsequent fixes) and added infrastructure files from phase-4-doxygen. This creates a complete branch with all documentation and tooling.
Add docs:generate and docs:validate tasks that were missing after merge conflict resolution.
Update plan references from phase-4-docs-clean worktree to continue-doxygen-sql-comments branch, which now contains all merged infrastructure files.
