From f4a397c1ecb839e390dd11972ea88c6bc3783964 Mon Sep 17 00:00:00 2001 From: Jens Tirsvad Nielsen Date: Mon, 5 Oct 2026 14:17:04 +0800 Subject: [PATCH] Fix tracing leak and review findings in the MIL-001 script Switch off set -x (it printed tokens), accept a byte order mark, strip the carriage return jq adds on Windows, return the first key without jq, rename the boolean keys, and cite the task in the header. Add regression tests and review record RC-016.

lists are arrays; tests use `[[ ]]` and `$(...)` | Pass | `shellcheck` is clean; no backticks or `[ ]`. | +| 3 | Names follow the conventions: `kebab-case.sh` files, `snake_case` functions and variables, `UPPER_SNAKE` constants and environment variables | Pass | Fixed during this review: the boolean keys `use_github` and `plan_gate` were renamed `has_github` and `is_plan_gate_enabled` (the `is_` / `has_` rule). | +| 4 | Passes `shellcheck` and `bash -n` with no unexplained `disable` comments | Pass | Clean with the tools above. Every `disable` carries its reason: SC2034 (namerefs and results read by callers), SC2094 (loop only uses the file name in messages), SC2004 (associative array key), and in `tests/` SC2016 and SC2034 (literal snippet text, results read by other files). | +| 5 | Errors go to standard error with an `error:` message and a non-zero exit code; bad or missing arguments print a usage line | Pass | `die` and `usage_error` (exit 1 and 2); tests cover an unknown option and an option without a value. | +| 6 | Temporary files use `mktemp` with a `trap ... EXIT` cleanup; no fixed `/tmp` names | Pass | Private directory created with `umask 077`; files removed one by one, directory with `rmdir`. Verified after a normal run, a failed run and SIGTERM (test added). SIGINT was not verified: see the action items. | +| 7 | No secret is written in the script, echoed, or put on a command line; secrets come from the environment or a gitignored file | Pass | Fixed during this review: under `bash -x` the script printed the token 47 times in the trace. Tracing is now switched off with a warning, and a test fails if the guard is removed (checked by mutation). Tokens go through a private curl config file, never the command line; output is redacted; error messages name the key and line, never the value. | +| 8 | A script that changes state outside its own directory defaults to a dry run or needs an explicit flag, and says so in its header | Pass | This version contacts no host and changes nothing; the header says so. It only creates a private temporary directory, removed on exit. | +| 9 | A header comment states purpose, usage, options, environment variables and exit codes | Pass | All present, plus files, requirements, tracing and what the script implements; `--help` prints it. | +| 10 | The script implements a task or design it cites; deviations are recorded | Pass | Fixed during this review: the header now cites MIL-001 tasks 1 to 6 (issues #3 to #8), US-001.01 and UC-001, and records the one deviation (the second `GITEA_URL` key is `GITEA_API_URL`). | +| 11 | Behaviour is tested for success, failure and any disabled or bypass path | Pass | 209 checks: successful runs with and without GitHub, bad input, missing tools, network failure, redaction, tracing, termination. The script has no bypass flag. Mutation checks: a planted token leak and the removed tracing guard were both caught. | +| 12 | Formatted with `shfmt` (or the project's formatter) | Pass | `shfmt -i 2 -ci` reports no difference. | +| 13 | Safe to re-run: a second run does not duplicate or corrupt what the first did | Pass | The script keeps no state. | +| 14 | Bash version and external tools it needs are stated; GNU-only options are named | Pass | Fixed during this review: the header now lists bash 4.4, git, curl, mktemp, optional jq, the base tools it calls and the GNU or BSD `stat` form. | + +## Defects found and fixed during this review + +| Defect | Fix | Test | +| --- | --- | --- | +| `bash -x` printed the tokens in the trace | Tracing is switched off with a warning | `test_tracing_does_not_leak_secrets` | +| A byte order mark on the first line of a config file gave an unclear "expected KEY=VALUE" error | The mark is ignored | `test_byte_order_mark_is_accepted` | +| `jq` on Windows added a carriage return to every value `json_get` returned | The carriage return is stripped | `test_json_get_with_and_without_jq` | +| `json_get` without `jq` returned the last occurrence of a key on one-line JSON | It returns the first occurrence | `test_json_get_with_and_without_jq` | + +## MIL-001 Go/No-Go check + +| # | Criterion | Result | +| --- | --- | --- | +| 1 | `shellcheck create-project.sh` reports no errors | Go: clean | +| 2 | Neither config file is `source`d; unknown keys and malformed lines are rejected | Go: parser tests, including values that would run a command | +| 3 | No token appears in stdout, stderr or a log in any test, including failure paths | Go: end-to-end and trace tests | +| 4 | Missing `git` or `curl` stops the script before any change | Go: empty `PATH` test, nothing created | +| 5 | `.env` is ignored by git; both example files contain placeholders only | Go: tested | +| 6 | All acceptance criteria of US-001.01 are met | Go: validation without execution, stop on a missing tool or bad value, prompts for every detail | + +## Overall Verdict + +Go — All mandatory criteria of QC-SH-001 pass after the fixes above, and all six MIL-001 Go/No-Go criteria are met.
