From 11697faed099a241621bca5172cbbaede19bb5d7 Mon Sep 17 00:00:00 2001 From: nelsoduarte Date: Sun, 21 Jun 2026 14:57:45 +0100 Subject: [PATCH 01/14] fix(installer): capture exc in lambda closure to prevent NameError (CRIT) When install_app raised, the except block scheduled lambdas via self.after() that referenced `exc` after the worker thread frame had unwound, so the after-callback hit NameError instead of showing the friendly error dialog. Capture str(exc) up front and bind it via a lambda default argument so the closure is independent of the enclosing frame's local-variable lifetime.

Add a shared utils.check_image_size helper using PIL.Image (already a dependency) to short-circuit before allocation, returning width/height for a localised warning. Apply at the two entry points the audit flagged: _SignatureDialog import tab in app/editor/dialogs.py and EditorTab._pick_image in app/editor/tab.py. Cap is 100 megapixels — generous enough for any phone-camera / scanner output, tight enough to refuse gigapixel attacks. Add editor.image_too_large key across all 8 supported languages.

On OneDrive-installed copies (Windows Store + manual installs of self-extracting setup into a synced folder) the .bak file became a visible sync entry, prompting OneDrive to upload the prior binary on every update — adds a couple of hundred MB of churn per release for users with the app under their OneDrive root. Move the backup to tempfile.gettempdir() via mkstemp, keeping the original basename + .pdfapps-backup suffix for forensics.

The raw exe embeds the runner's internal build paths in its PyInstaller debug strings — not a credential leak but free reconnaissance for anyone scraping the .exe for build-machine signatures. Users install via PDFAppsSetup.exe or the .msix; the in-app auto-updater (`_find_asset` in app/updater.py) already targets PDFAppsSetup.exe on Windows, so this is a no-op for the update flow. Drop PDFApps.exe from the three places it appeared in build.yml: matrix upload, sha256 checksum loop, and release files list.

Where the fix has an observable runtime effect (image-cap guard, atomic save, config-driven max-recent, short-path helper) the test calls the helper directly with stubs/monkeypatch; where the effect is in CI / installer / GUI code, the test grep-asserts on the source file so future regressions are caught at lint time. Notably: - check_image_size: normal-image accept, gigapixel reject (PIL stub to avoid OOM), corrupt-file fallback - _atomic_save: success path replaces, failure leaves prior content untouched and cleans up the tempfile - _get_max_recent: default + config override + clamp tests - ruff F401/F541/E741 subprocess check guards future regressions Co-Authored-By: Claude Opus 4.7 --- tests/test_audit_pr_j.py | 313 +++++++++++++++++++++++++++++++++++++++ 1 file changed, 313 insertions(+) create mode 100644 tests/test_audit_pr_j.py diff --git a/tests/test_audit_pr_j.py b/tests/test_audit_pr_j.py new file mode 100644 index 0000000..a776751 --- /dev/null +++ b/tests/test_audit_pr_j.py @@ -0,0 +1,313 @@ +"""Regression tests for PR-J audit cleanup (13 fixes). + +Each test exercises one of the fixes either via direct call (preferred) +or via source-grep when the production behaviour depends on a GUI / +subprocess / OS call we cannot reasonably stage from a unit test. +""" + +import io +import json +import os +import sys +from pathlib import Path + +import pytest + +_REPO_ROOT = Path(__file__).resolve().parent.parent +sys.path.insert(0, str(_REPO_ROOT)) + + +# ── Fix #1: installer NameError on error path ───────────────────────────── + +def test_installer_exc_lambda_captures_message(): + """The installer error path must capture str(exc) into the lambda's + default argument so the after-callback does not blow up with + NameError when the worker frame unwinds. + """ + src = (_REPO_ROOT / "installer.py").read_text(encoding="utf-8") + # Find the install_app worker except block.
