From 476f9e2e6544268ba2f569920fd7eca862dce032 Mon Sep 17 00:00:00 2001 From: Jaixii Date: Fri, 21 Aug 2026 19:38:42 -0400 Subject: [PATCH 1/3] cowork-bot: fix terraform rollback generator correctness and safety - Empty plans now short-circuit to '# No changes to roll back' instead of emitting a header plus a dangerous blanket 'terraform destroy -auto-approve && terraform apply -auto-approve' suggestion for a plan with no changes. - Replacements (create-before-delete / delete-before-create / replace) no longer produce contradictory destroy + apply commands for the same resource; they revert via apply of the previous config only. - Pure creates get destroy; pure deletes get an explicit restore comment before their apply. - Added regression tests (tests/test_rollback_safety.py); updated the empty-plan edge-case test to assert the new safe behavior. 125/125 green, ruff clean. --- .gitattributes | 7 - .github/CODEOWNERS | 1 - .github/FUNDING.yml | 4 - .github/ISSUE_TEMPLATE/bug_report.md | 30 - .github/ISSUE_TEMPLATE/config.yml | 8 - .github/ISSUE_TEMPLATE/feature_request.md | 22 - .github/PULL_REQUEST_TEMPLATE.md | 26 - .github/dependabot.yml | 21 - .github/workflows/auto-code-review.yml | 28 - .github/workflows/ci.yml | 38 - .github/workflows/cowork-auto-pr.yml | 36 - .github/workflows/pages.yml | 43 - .github/workflows/publish.yml | 55 - .gitignore | 89 -- .pre-commit-config.yaml | 17 - AGENTS.md | 38 - CHANGELOG.md | 69 -- CONTRIBUTING.md | 35 - LICENSE | 22 - README.md | 159 --- SECURITY.md | 23 - cli.js | 9 - eslint.config.mjs | 21 - package.json | 54 - pyproject.toml | 78 -- src/deploydiff/__init__.py | 3 - src/deploydiff/__main__.py | 5 - src/deploydiff/cli.py | 278 ----- src/deploydiff/cloudformation_parser.py | 112 -- src/deploydiff/cost_estimator.py | 259 ----- src/deploydiff/diff_renderer.py | 175 --- src/deploydiff/mcp_server.py | 45 - src/deploydiff/models.py | 121 -- src/deploydiff/pulumi_parser.py | 145 --- src/deploydiff/py.typed | 0 src/deploydiff/rollback.py | 43 +- src/deploydiff/terraform_parser.py | 121 -- tests/__init__.py | 0 tests/conftest.py | 21 - tests/smoke.test.js | 26 - tests/test_deploydiff.py | 1274 --------------------- tests/test_edge_cases.py | 5 +- tests/test_parse_errors.py | 61 - tests/test_rollback_safety.py | 50 + 44 files changed, 88 insertions(+), 3589 deletions(-) delete mode 100644 .gitattributes delete mode 100644 .github/CODEOWNERS delete mode 100644 .github/FUNDING.yml delete mode 100644 .github/ISSUE_TEMPLATE/bug_report.md delete mode 100644 .github/ISSUE_TEMPLATE/config.yml delete mode 100644 .github/ISSUE_TEMPLATE/feature_request.md delete mode 100644 .github/PULL_REQUEST_TEMPLATE.md delete mode 100644 .github/dependabot.yml delete mode 100644 .github/workflows/auto-code-review.yml delete mode 100644 .github/workflows/ci.yml delete mode 100644 .github/workflows/cowork-auto-pr.yml delete mode 100644 .github/workflows/pages.yml delete mode 100644 .github/workflows/publish.yml delete mode 100644 .gitignore delete mode 100644 .pre-commit-config.yaml delete mode 100644 AGENTS.md delete mode 100644 CHANGELOG.md delete mode 100644 CONTRIBUTING.md delete mode 100644 LICENSE delete mode 100644 README.md delete mode 100644 SECURITY.md delete mode 100644 cli.js delete mode 100644 eslint.config.mjs delete mode 100644 package.json delete mode 100644 pyproject.toml delete mode 100644 src/deploydiff/__init__.py delete mode 100644 src/deploydiff/__main__.py delete mode 100644 src/deploydiff/cli.py delete mode 100644 src/deploydiff/cloudformation_parser.py delete mode 100644 src/deploydiff/cost_estimator.py delete mode 100644 src/deploydiff/diff_renderer.py delete mode 100644 src/deploydiff/mcp_server.py delete mode 100644 src/deploydiff/models.py delete mode 100644 src/deploydiff/pulumi_parser.py delete mode 100644 src/deploydiff/py.typed delete mode 100644 src/deploydiff/terraform_parser.py delete mode 100644 tests/__init__.py delete mode 100644 tests/conftest.py delete mode 100644 tests/smoke.test.js delete mode 100644 tests/test_deploydiff.py delete mode 100644 tests/test_parse_errors.py create mode 100644 tests/test_rollback_safety.py diff --git a/.gitattributes b/.gitattributes deleted file mode 100644 index 02f8aef..0000000 --- a/.gitattributes +++ /dev/null @@ -1,7 +0,0 @@ -# Auto-detect text files and normalize to LF -* text=auto eol=lf - -# Windows scripts must use CRLF -*.bat text eol=crlf -*.cmd text eol=crlf -*.ps1 text eol=crlf diff --git a/.github/CODEOWNERS b/.github/CODEOWNERS deleted file mode 100644 index 67b22f4..0000000 --- a/.github/CODEOWNERS +++ /dev/null @@ -1 +0,0 @@ -* @Coding-Dev-Tools diff --git a/.github/FUNDING.yml b/.github/FUNDING.yml deleted file mode 100644 index 8f036f5..0000000 --- a/.github/FUNDING.yml +++ /dev/null @@ -1,4 +0,0 @@ -# These are supported funding model platforms - -github: [Coding-Dev-Tools] # Replace with actual GitHub Sponsors username when enrolled -custom: ['https://revenueholdings.dev'] diff --git a/.github/ISSUE_TEMPLATE/bug_report.md b/.github/ISSUE_TEMPLATE/bug_report.md deleted file mode 100644 index 4cc17e2..0000000 --- a/.github/ISSUE_TEMPLATE/bug_report.md +++ /dev/null @@ -1,30 +0,0 @@ ---- -name: Bug Report -about: Report a bug to help us improve -title: '[Bug] ' -labels: bug -assignees: '' ---- - -**Describe the Bug** -A clear and concise description of what the bug is. - -**To Reproduce** -Steps to reproduce the behavior: -1.

[PATCH 3/3] cowork-bot: fail loudly on non-plan JSON inputs All three parsers (terraform/cfn/pulumi) silently returned an empty plan for any well-formed JSON that was not a plan file, so the CLI reported "no changes" and exited 0 - a silent-green trap. Add PlanFormatError raised on structural mismatch, validated immediately after input load, and surface it in _load_plan as a red CLI error with exit 1. +13 regression tests. --- .gitattributes | 7 - .github/CODEOWNERS | 1 - .github/FUNDING.yml | 4 - .github/ISSUE_TEMPLATE/bug_report.md | 30 ---- .github/ISSUE_TEMPLATE/config.yml | 8 -- .github/ISSUE_TEMPLATE/feature_request.md | 22 --- .github/PULL_REQUEST_TEMPLATE.md | 26 ---- .github/dependabot.yml | 21 --- .github/workflows/auto-code-review.yml | 28 ---- .github/workflows/ci.yml | 38 ------ .github/workflows/cowork-auto-pr.yml | 36 ----- .github/workflows/pages.yml | 43 ------ .github/workflows/publish.yml | 55 -------- .gitignore | 89 ------------ .pre-commit-config.yaml | 17 --- AGENTS.md | 38 ------ CHANGELOG.md | 69 ---------- CONTRIBUTING.md | 35 ----- LICENSE | 22 --- README.md | 159 ---------------------- SECURITY.md | 23 ---- cli.js | 9 -- eslint.config.mjs | 21 --- package.json | 54 -------- pyproject.toml | 78 ----------- src/deploydiff/cli.py | 18 ++- src/deploydiff/cloudformation_parser.py | 5 +- src/deploydiff/models.py | 4 + src/deploydiff/pulumi_parser.py | 9 +- src/deploydiff/terraform_parser.py | 5 +- tests/test_plan_format_validation.py | 68 +++++++++ 31 files changed, 99 insertions(+), 943 deletions(-) delete mode 100644 .gitattributes delete mode 100644 .github/CODEOWNERS delete mode 100644 .github/FUNDING.yml delete mode 100644 .github/ISSUE_TEMPLATE/bug_report.md delete mode 100644 .github/ISSUE_TEMPLATE/config.yml delete mode 100644 .github/ISSUE_TEMPLATE/feature_request.md delete mode 100644 .github/PULL_REQUEST_TEMPLATE.md delete mode 100644 .github/dependabot.yml delete mode 100644 .github/workflows/auto-code-review.yml delete mode 100644 .github/workflows/ci.yml delete mode 100644 .github/workflows/cowork-auto-pr.yml delete mode 100644 .github/workflows/pages.yml delete mode 100644 .github/workflows/publish.yml delete mode 100644 .gitignore delete mode 100644 .pre-commit-config.yaml delete mode 100644 AGENTS.md delete mode 100644 CHANGELOG.md delete mode 100644 CONTRIBUTING.md delete mode 100644 LICENSE delete mode 100644 README.md delete mode 100644 SECURITY.md delete mode 100644 cli.js delete mode 100644 eslint.config.mjs delete mode 100644 package.json delete mode 100644 pyproject.toml create mode 100644 tests/test_plan_format_validation.py diff --git a/.gitattributes b/.gitattributes deleted file mode 100644 index 02f8aef..0000000 --- a/.gitattributes +++ /dev/null @@ -1,7 +0,0 @@ -# Auto-detect text files and normalize to LF -* text=auto eol=lf - -# Windows scripts must use CRLF -*.bat text eol=crlf -*.cmd text eol=crlf -*.ps1 text eol=crlf diff --git a/.github/CODEOWNERS b/.github/CODEOWNERS deleted file mode 100644 index 67b22f4..0000000 --- a/.github/CODEOWNERS +++ /dev/null @@ -1 +0,0 @@ -* @Coding-Dev-Tools diff --git a/.github/FUNDING.yml b/.github/FUNDING.yml deleted file mode 100644 index 8f036f5..0000000 --- a/.github/FUNDING.yml +++ /dev/null @@ -1,4 +0,0 @@ -# These are supported funding model platforms - -github: [Coding-Dev-Tools] # Replace with actual GitHub Sponsors username when enrolled -custom: ['https://revenueholdings.dev'] diff --git a/.github/ISSUE_TEMPLATE/bug_report.md b/.github/ISSUE_TEMPLATE/bug_report.md deleted file mode 100644 index 4cc17e2..0000000 --- a/.github/ISSUE_TEMPLATE/bug_report.md +++ /dev/null @@ -1,30 +0,0 @@ ---- -name: Bug Report -about: Report a bug to help us improve -title: '[Bug] ' -labels: bug -assignees: '' ---- - -**Describe the Bug** -A clear and concise description of what the bug is. - -**To Reproduce** -Steps to reproduce the behavior: -1.
