From 196f55c58edf0f17eafb4e8ee8edad4a909ceb0d Mon Sep 17 00:00:00 2001 From: Kevin Veen-Birkenbach Date: Tue, 9 Dec 2025 17:12:23 +0100 Subject: [PATCH] feat(repository/pull): improve verification logic and add full unit test suite MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This commit enhances the behaviour of pull_with_verification() and adds a comprehensive unit test suite covering all control flows. Changes: - Added `preview` parameter to fully disable interaction and execution. - Improved verification logic: * Prompt only when not in preview, verification is enabled, verification info exists, and verification failed. * Skip prompts entirely when --no-verification is set. - More explicit construction of `git pull` command with optional extra args. - Improved messaging and formatting for clarity. - Ensured directory existence is checked before any verification logic. - Added detailed comments explaining logic and conditions. Tests: - New file tests/unit/pkgmgr/actions/repos/test_pull_with_verification.py - Covers: * Preview mode (no input, no subprocess) * Verification failure – user rejects * Verification failure – user accepts * Verification success – immediate git call * Missing repository directory – skip silently * --no-verification flag bypasses prompts * Command formatting with extra args - Uses systematic mocking for identifier, repo-dir, verify_repository(), subprocess.run(), and user input. This significantly strengthens correctness, UX, and test coverage of the repository pull workflow. https://chatgpt.com/share/69384aaa-0c80-800f-b4b4-64e6fbdebd3b --- pkgmgr/actions/repository/pull.py | 49 ++- .../repos/test_pull_with_verification.py | 309 ++++++++++++++++++ 2 files changed, 348 insertions(+), 10 deletions(-) create mode 100644 tests/unit/pkgmgr/actions/repos/test_pull_with_verification.py diff --git a/pkgmgr/actions/repository/pull.py b/pkgmgr/actions/repository/pull.py index c0cdc87..f6d02d7 100644 --- a/pkgmgr/actions/repository/pull.py +++ b/pkgmgr/actions/repository/pull.py @@ -1,35 +1,57 @@ import os import subprocess import sys + from pkgmgr.core.repository.identifier import get_repo_identifier from pkgmgr.core.repository.dir import get_repo_dir from pkgmgr.core.repository.verify import verify_repository + def pull_with_verification( selected_repos, repositories_base_dir, all_repos, extra_args, no_verification, - preview:bool): + preview: bool, +) -> None: """ - Executes "git pull" for each repository with verification. - - Uses the verify_repository function in "pull" mode. - If verification fails (and verification info is set) and --no-verification is not enabled, - the user is prompted to confirm the pull. + Execute `git pull` for each repository with verification. + + - Uses verify_repository() in "pull" mode. + - If verification fails (and verification info is set) and + --no-verification is not enabled, the user is prompted to confirm + the pull. + - In preview mode, no interactive prompts are performed and no + Git commands are executed; only the would-be command is printed.
