#!/usr/bin/env python3 """ UnbundleDB // Zero-Dependency Client-Side PL/SQL Sanitizer, Hazard Scanner & Case-Morphing De-Obfuscation Restore CLI =============================================================================== 48-Hour Enterprise PL/SQL Package Challenge Tool File: /cli/unbundledb-sanitize.py 100% Python 3 Standard Library Only (re, sys, json, hashlib, argparse, pathlib, datetime, shutil, subprocess). Zero external pip dependencies. Modes Supported: 1. `--sanitize` (Default when `--ddl` and `--plsql` are provided): - Deterministically obfuscates proprietary Table names (`TBL_001`..), Column names (`COL_001`..), Sequences (`SEQ_001`..), Constraints (`CST_001`..), Packages (`PKG_001`..), Procedures (`PROC_001`..), Functions (`FN_001`..), Parameters (`p_param_001`..), Local Variables (`v_var_001`..), Exceptions (`e_exc_001`..), and business String Literals (`STR_REDACTED_01`..). - Strictly preserves all Oracle SQL & PL/SQL reserved words, data types (`NUMBER(15,2)`, `VARCHAR2(50)`), empty-string `''` NULL traps, and control-flow / exception structures. - Generates `private_identifier_map.json` ("KEEP LOCAL - DO NOT SEND TO UNBUNDLEDB") containing full multi-case restoration variants (`UPPER_SNAKE`, `lower_snake`, `PascalCase`, `SingularPascalCase`, `camelCase`, and `string_literals`). - Scans for 6 critical Oracle-to-Postgres/Go migration hazard categories and outputs both an ANSI terminal dashboard and `hazard_readiness_report.md`. 2. `--restore`: - CLI signature: `python3 unbundledb-sanitize.py --restore --map --in-dir --out-dir ` - Recursively processes all `.go`, `.sql`, `.md`, and `.json` files in `--in-dir`. - Sorts anonymized tokens by length descending (preventing partial token corruption such as `TBL_0010` vs `TBL_001`) and restores every casing variant (`TBL_001` -> `ACCOUNTS`, `tbl_001` -> `accounts`, `Tbl001` -> `Accounts`, `Col001` -> `AccountID`, `STR_REDACTED_01` -> original string literal). - Runs `gofmt -w` on restored `.go` files if `gofmt` is available on PATH.
