Full Changelog: v3.2.0...v4.0.0

v3.2.0

Added

• inno audit subcommand — New subcommand for directory-wide integrity scanning, health metrics, and checksum mismatch detection. Three modes: default integrity (inno audit -d <datadir>), health (--health), and mismatch listing (--checksum-mismatch). Scans .ibd files in parallel with rayon. Supports --json, --csv, and --prometheus output formats, threshold filters (--min-fill-factor, --max-fragmentation), and --keyring for encrypted tablespaces.
• --audit-log <path> global flag — Structured NDJSON audit logging for write operations (repair, corrupt, defrag, transplant). AuditLogger with mutex + fs2 file locking, AuditEvent tagged enum (session_start, page_write, file_write, backup_created, session_end).
• --prometheus flag on inno audit and inno health — Prometheus exposition format output for integration with textfile collectors. Per-file and directory-wide gauge metrics for pages, corruption, fill factor, fragmentation, garbage ratio, and scan duration.
• inno watch --events — Structured NDJSON change event stream. Emits watch_start, page_change, watch_error, and watch_stop events with per-page detail (page type, LSN delta, checksum validity).
• inno repair --batch <dir> — Batch repair mode scanning a data directory for corrupt tablespaces and repairing them in parallel. Auto-detects checksum algorithm per file. BatchRepairReport JSON output with per-file results and summary.
• inno find --corrupt — Scan data directory for pages with checksum mismatches.
• --depth flag on inno find, inno tsid, and inno audit — Control recursive directory scanning depth. Default depth 2, --depth 0 for unlimited, --depth N for N levels. Symlink loop detection via canonical path tracking.
• Shell completion generation — inno completions <shell> generates completions for bash, zsh, fish, and PowerShell via clap_complete.
• Web UI audit dashboard — New "Audit" tab in the web analyzer for multi-file integrity and health analysis. Drop 3+ .ibd files to see summary cards (total files, pages, corrupt pages, integrity %, avg fill factor), progress bars for integrity and fragmentation, and a sortable/filterable per-file detail table.
• WASM analyze_health() binding — New wasm-bindgen export for B+Tree health analysis from in-memory tablespace bytes.
• New src/util/prometheus.rs module with Prometheus exposition format helpers
• New src/util/audit.rs module with AuditLogger and AuditEvent types
• New web/src/components/audit.js audit dashboard component
• 30+ new integration tests across audit, find, health, and watch test files

Changed

• find_tablespace_files() rewritten with configurable depth and symlink loop safety via HashSet<PathBuf> canonical path tracking
• Web UI dropzone extended for 3+ file multi-drop (audit mode)
• Web UI tab bar conditionally shows Audit tab (keyboard shortcut: 0)

v2.1.0

Added

• Redo log analysis in web UI — New "Redo Log" tab auto-detects redo log files (ib_logfile*, #ib_redo*) and displays file header, checkpoint slots, block-level analysis with filtering, and MLOG record type distribution. Uses the existing parse_redo_log WASM function. (Closes #21)
• Export functionality — Download JSON and Copy to Clipboard buttons on every analysis tab. "Export All" button in the analyzer header runs all analysis functions and downloads a combined JSON file. Shared utilities in web/src/utils/export.js. (Closes #31)
• Page type heatmap — New "Heatmap" tab renders a canvas-based grid visualization of all pages, color-coded by page type. Three color modes: Page Type (categorical), LSN Age (blue-to-red gradient), and Checksum Status (green/red/gray). Supports mouse wheel zoom, click-and-drag pan, hover tooltips, and click-to-inspect navigation to the Pages tab. (Closes #25)
• Record-level INDEX page inspection — "View Records" button on INDEX pages in the Pages tab. Displays individual B+Tree record headers (type, heap number, n_owned, delete mark, min_rec, next offset) and raw hex bytes. Supports both compact (MySQL 5.0+) and redundant (pre-5.0) row formats. New inspect_index_records WASM function. (Closes #23)
• Encrypted tablespace support in web UI — Automatic encryption detection with keyring file upload banner. New decrypt_tablespace and get_encryption_info WASM functions. Decrypted data is transparently passed to all analysis tabs. (Closes #29)
• Redundant row format parsing — New RedundantRecordHeader struct and walk_redundant_records() function in innodb::record for pre-MySQL 5.0 row format support. Parses 6-byte headers with n_fields, one_byte_offs flag, and absolute next-record offsets.
• Accessibility improvements — ARIA role="tablist"/role="tab" attributes with arrow key navigation, scope="col" on all table headers, skip-to-content link, keyboard shortcuts panel (? key), aria-live announcements for tab changes, focus-visible outlines, reduced-motion and high-contrast media queries, visible theme toggle button. (Closes #32)
• MySQL 9.0/9.1 test fixtures and integration tests (compressed, multipage, standard, redo logs)
• Percona Server 8.0/8.4 test fixtures and integration tests
• MySQL 9.x redo log format support (version-conditional parsing for pre/post-8.0.30 layouts)
• Memory-mapped I/O (--mmap flag) for large tablespace analysis
• Streaming analysis mode (--streaming flag) for memory-constrained environments
• Criterion benchmarking infrastructure for core operations
• Docker image with multi-arch support and GitHub Actions workflow
• npm package for WASM module with TypeScript types
• deb and rpm package generation in release workflow
• AUR PKGBUILD for Arch Linux packaging
• Reference Homebrew formula for homebrew-core submission
• Git LFS tracking for binary test fixtures
• LICENSE file (MIT)
• 3 unit tests for redundant record header parsing and RecordHeader enum accessors

Changed

• BREAKING: RecordInfo.header changed from CompactRecordHeader to RecordHeader enum (wrapping Compact or Redundant variants). Direct field access (e.g. rec.header.heap_no) must be replaced with accessor methods (e.g. rec.header.heap_no()). This enables unified handling of both compact and redundant row formats.
• PageType::Unknown now carries original type code as Unknown(u16), preserving unrecognized page type values
• Benchmarks use iter_batched instead of cloning data inside b.iter() for accurate timing
• Web UI tab bar now includes Heatmap (key 7) and conditionally shows Diff (key 8) and Redo Log (key 9)
• Diff view grid is now responsive (grid-cols-1 md:grid-cols-2)
• Keyboard shortcuts no longer fire when a <select> element has focus

Fixed

• XSS in heatmap tooltip — numeric values (page_number, lsn) are now escaped with esc()
• Memory leak in heatmap — mouseup listener scoped to canvas instead of window, with mouseleave cleanup
• recover now threads vendor_info to validate_checksum(), fixing MariaDB full_crc32 recovery assessment
• Bounds checks in checksum and parse parallel paths prevent out-of-bounds access on truncated files
• find --first files_searched counter correctly counts all opened files from parallel results
• Progress bars in checksum, parse, and find display during parallel work instead of after
• Corrected PageType enum values and added missing page types
• LogFileHeader::parse() version-conditional layout for pre-8.0.30 redo logs
• CI test job fetches Git LFS objects for binary fixture files
