Linux: a .tar.gz package with its own menu entry by donislawdev · Pull Request #298 · donislawdev/BeanNetworkTester

donislawdev · 2026-10-28T13:56:04Z

What and why

Linux gets a package of the same kind as the Windows zip: the PyInstaller onedir bundle from the
same spec, as a .tar.gz. Unpack it and run BeanNetworkTester; no Python is needed on the
system. Built on ubuntu-24.04, the oldest supported release, because the libraries in the bundle
come from the system it is built on. This pull request builds and checks it in CI and makes the
program right when frozen on Linux. Publishing it with a release is the next pull request.

The frozen program on Linux

Frozen, the program still behaved as the Windows one:

user files went to ~/AppData/Local/BeanNetworkTester, and to root's folder under sudo or
pkexec. They now go to $XDG_CONFIG_HOME (absolute only, as the XDG spec says) or
~/.config, and to the person's own folder when root runs for them (paths.config_home);
commands said BeanNetworkTester.exe. The repro line, --help and the copied command name the
program: sudo ~/<folder>/BeanNetworkTester, without sudo for --simulate;
the bootloader points LD_LIBRARY_PATH at the bundle, and every program started from the window
inherited it. A system program then loads the bundle's older libraries and stops
(fc-match: symbol lookup error, measured on Ubuntu 26.04, Fedora 44 and Arch). The person's
own value is put back first thing (linuxenv.restore_library_path);
a Tk that cannot load a library of the system said "No tkinter"; the line names the library.

What the bundle carries

tools/linux_bundle.py holds the list, the spec reads it, and CI checks the built folder:

fontconfig, freetype and what they read with come from the system. A bundled fontconfig reads
the system's configuration, and one from 24.04 printed 15 warnings on Arch (fontconfig 2.18).
libXft stays: without it a system that lacks it opened no window;
libXau and libXdmcp come from the system: its libxcb, which the bundle never carries, needs both;
_bz2, _lzma and _zstd are left out: the program uses none of them.

The menu entry

--install-desktop writes com.donislawdev.BeanNetworkTester.desktop into the person's
applications folder and --remove-desktop removes it. Only the package does it, never as root.
Exec is the program, not pkexec, quoted as the Desktop Entry Specification says; a program path
with =, which the specification allows in no form, is refused. The entry is written through a
temporary file of its own, so two installs at once cannot truncate each other's. The window is
created with a class of its own, so GNOME matches it to the entry: Tk title-cases the class
(measured: "BeanNetworkTester" became "Beannetworktester"), so it is written in that form.

Licences

legal.py keeps one list per build and COMPONENTS is this system's, so --license reports what
the copy carries. The Linux list was read off the bundle CI built: libX11, libXext, libXft,
libXrender, libXss, libffi, zlib, Tcl/Tk 8.6, libpython, and pydivert's libebpfdivert.so, which
carries libbpf, elfutils' libelf, Zstandard and zlib inside it. The X.Org libraries' copyright
files in licenses/ are the ones Ubuntu 24.04 ships with them. The parts of libebpfdivert.so
are built from their own sources by eBPFDivert 0.0.5's release script, at the versions
legal.EBPFDIVERT_PARTS records (libbpf 1.7.0, elfutils 0.192, Zstandard 1.5.7, and zlib 1.2.11
from its build image), so licenses/ holds those projects' own licence files at those versions,
--license and the SBOM report them, and a test on Linux fails when pydivert brings another
eBPFDivert. THIRD-PARTY-NOTICES.md names each with the build that carries it, and
tools/sbom.py --platform writes either build's SBOM.

CI

A new job, "build the Linux package" (not in the ruleset), builds it, checks the libraries, runs
tools/ci_linux_package_smoke.py under Xvfb (exit codes, the Reproduce line, the user files
folder, a window that opens without a word on stderr, its class, the menu entry against
desktop-file-validate), captures for real with the frozen program
(ci_linux_capture_smoke.py --program, in a namespace of its own), scans it with Syft against the
registry and uploads the .tar.gz.

Checked

The new and edited tests pass on Windows and on Linux (WSL), and the new ones fail on the old
code. Both new tools are shown to fail: the package smoke named all three faults of a bundle
built from master.
A bundle built on Ubuntu 24.04 opens its window on Ubuntu 26.04, Fedora 44 and Arch, and
captures for real (0.15, 100.7 and 0.05 ms before, during and after --latency 50).
The CI artifact on an Ubuntu 26.04 desktop (GNOME, Wayland), started from its menu entry: the
polkit dialog, then the root copy under the person's process, the bean icon and name in the dock,
the window file the person's and no root file; after Cancel the window opens without root and
GitHub opens the browser.
CI on 0f2f9cc: all checks green, and all 168 mutations of the changed files caught.
Not run locally: the full suite and mutate.py.

Summary by CodeRabbit

New Features
- Added a Linux package for Bean Network Tester, with support for installing or removing its application-menu entry.
- Linux frozen builds use the platform’s executable name and store user data in the standard configuration location.
Bug Fixes
- Linux startup errors now identify missing system libraries more clearly, and command-line use remains available when GUI libraries are missing.
- Linux windows now use an application-specific window class.

The Linux package will be the same PyInstaller bundle as the Windows zip. Frozen on Linux, the program still behaved as the Windows one: - user files went to ~/AppData/Local/BeanNetworkTester, and to root's folder under sudo or pkexec. They now go to $XDG_CONFIG_HOME (absolute only, as the XDG spec says) or ~/.config, and to the person's own folder when root runs for them (paths.config_home). Nothing is adopted from beside the program: no Linux build ever kept files there. - commands said BeanNetworkTester.exe. The repro line, --help and the copied command now name the program the way the person runs it: `sudo ~/<folder>/BeanNetworkTester`, without sudo for --simulate, and ./BeanNetworkTester when it is outside the home, so no path from the machine reaches a shared report. - the bootloader points LD_LIBRARY_PATH at the bundle, and every program started from the window inherited it. A system program then loads the bundle's older libraries and stops (fc-match: "symbol lookup error", measured on Ubuntu 26.04, Fedora 44 and Arch); the browser is one. The person's own value is put back first thing (restore_library_path). - a Tk that cannot load a library of the system said "No tkinter". The line now names the library and still offers the command line. Windows and running from sources keep their behaviour; each new branch needs Linux and a frozen build. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

The Linux .tar.gz is the same PyInstaller onedir bundle as the Windows zip, from the same spec: - the spec imports PyInstaller's win32 version-resource module only on Windows (on Linux it fails: "cannot import name 'win32api'") and gives the .ico to Windows only. - on Linux the bundle takes fontconfig, freetype, expat, libpng and brotli from the system instead of carrying them. A bundled fontconfig reads the system's configuration, and one built on Ubuntu 24.04 printed 15 warnings on Arch (fontconfig 2.18) and dropped those rules. libXft stays: without it a system that lacks it opened no window. The list is tools/linux_bundle.py, which also checks a built bundle. A new job, "build the Linux package", builds it on ubuntu-24.04, the oldest supported release, because the libraries come from the system it is built on. It checks the libraries, runs tools/ci_linux_package_smoke.py under Xvfb (exit codes, the Reproduce: line, the user files folder, a window that opens without a word on stderr), captures for real with the frozen program (ci_linux_capture_smoke.py --program, in a namespace of its own) and uploads the .tar.gz. The weekly notice watches it. Both new tools are shown to fail: the smoke named all three faults of a bundle built from master (BeanNetworkTester.exe twice, ~/AppData/Local). Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

`BeanNetworkTester --install-desktop` writes one Desktop Entry, com.donislawdev.BeanNetworkTester.desktop, into $XDG_DATA_HOME/applications (else ~/.local/share/applications); `--remove-desktop` removes that file and nothing else. Only the Linux package does it, and never as root: under sudo the file would be root's, in the person's folder. - Exec is the program itself, not pkexec: the window asks for root on its own. The path is quoted as the Desktop Entry Specification says (a double quote, backtick, dollar sign and backslash are escaped, then the value's own backslash escape applies on top, and a percent sign is doubled), and a path with a control character is refused. - StartupWMClass is the window's class. Tk's default class is "Tk", which GNOME matches to no entry, so the root window is now created with a class of its own. Tk title-cases the class it is given (measured with xwininfo: "BeanNetworkTester" became "Beannetworktester"), so the class is written in that form in both places. The package smoke in CI now also checks the window's class, and that the entry --install-desktop writes passes desktop-file-validate, starts this program and goes away with --remove-desktop.

Walkthrough

This pull request adds a Linux package build, Linux-specific runtime and data paths, desktop-entry management, platform-specific legal and SBOM records, and CI checks for the packaged executable.

Changes: Linux Package Support

Layer / File(s)	Summary
Bundle definition and CI build `BeanNetworkTester.spec`, `tools/linux_bundle.py`, `tests/test_linux_bundle.py`, `.github/workflows/ci.yml`	The spec filters Linux bundle contents. The checker reports excluded or missing libraries. CI builds, checks, and uploads the Linux archive.
Linux runtime paths and commands `beantester/appinfo.py`, `beantester/paths.py`, `beantester/linuxenv.py`, `beantester/cli.py`, `tests/test_cli_runtime.py`, `tests/test_summary_repro_views.py`, `tests/test_user_data_location.py`, `tests/test_linuxenv.py`, `tests/test_crashlog.py`, `CHANGELOG.md`	Linux frozen builds use Linux executable names, command construction, and configuration paths. Startup restores the library path and reports missing shared libraries when Tk cannot load.
Desktop-entry management `beantester/desktop.py`, `beantester/cli.py`, `tests/test_desktop.py`, `README.md`	The CLI installs or removes a Linux desktop entry. The module generates escaped entry contents, checks eligibility, and handles filesystem results. The GUI uses the entry’s window class.
Platform legal inventory and SBOM `beantester/legal.py`, `tools/sbom.py`, `THIRD-PARTY-NOTICES.md`, `licenses/*`, `tests/test_license_surface.py`, `tests/test_sbom.py`, `tests/test_windows.py`, `tests/test_mutation_registry.py`	The legal registry and SBOM tools select components by platform. Notices, license texts, and tests cover Linux package components and their licensing records.
Packaged executable validation `tools/ci_linux_capture_smoke.py`, `tools/ci_linux_package_smoke.py`, `tests/test_ci_linux_capture_smoke.py`, `tests/test_ci_linux_package_smoke.py`, `.github/workflows/ci.yml`, `README.md`, `tests/test_mutation_registry.py`	Smoke checks validate packaged command output, GUI startup, desktop-entry behavior, and capture sessions. The CI job runs these checks and includes its result in the weekly issue workflow.

Merge Risk: Moderate · previous review 0f2f9

The Linux package ships third-party licence notices that name the wrong source for the libraries embedded in its eBPF library, which should be corrected before release. The desktop-menu installer and its CI check also have small robustness gaps that are quick to fix.

Full details: Tests For Changed Behavior

Explanation

The PR adds tests for the changed runtime behavior. Coverage includes Linux command and executable naming, config paths and migration, library-path restoration and startup order, missing-library reporting, desktop entry install/remove and window class, Linux bundle checks, capture/package smoke helpers, legal registries, and Linux SBOM generation. The test diff shows no deleted tests or weakened existing assertions; the changed platform-specific assertions and written-offer checks preserve or strengthen coverage. The only new skip is conditional validation when desktop-file-validate is unavailable.

Full details: No Secrets Or Debug Leftovers

Explanation

No forbidden agent or .env files were added. The scan found no credentials, private keys, internal hosts, or personal contact data. URLs and e-mail addresses are public upstream licence/source notices. Absolute paths such as /u/ana and /root occur only as synthetic test fixtures. Added print() calls provide normal CI/tool status and failure reporting, not debug leftovers.

Full details: No Hardcoded Ui Styling

Explanation

The PR changes Tkinter startup only to set className=desktop.WINDOW_CLASS and updates startup error handling. It adds no literal colors, fonts, font sizes, margins, paddings, sizes, or corner radii to individual controls, and adds no copied GUI controls. desktop.py writes menu-entry metadata rather than GUI styling.

Full details: No Obvious Performance Problems

Explanation

No clear performance problem is introduced. Runtime changes perform only constant-size environment, path, and desktop-entry work before or outside Tk's event loop; component_rows performs a small fixed registry lookup for --license. The new bundle/SBOM and smoke scripts run in CI, and their bounded file scans and subprocess checks do not match the specified large-input or excessive-polling failures.

Full details: System Changes Are Reversible

Explanation

The Linux package activates the existing eBPFDivert capture path, but it does not add persistent host rules. The session applies the user-selected filter, closes the divert first on every engine stop path, and removes the live engine from the exit cleanup set. CLI finally cleanup, GUI stop/window-close handling, watchdog fail-stop, and the Linux backend's kernel cleanup after process termination restore normal traffic. The CLI reports Ctrl+C to stop, and the GUI exposes Stop. The CI capture is also bounded by a private network namespace, destination filters, and a duration.

Full details: No Resource Leaks

Explanation

No resource leak is introduced. beantester/desktop.py:117-123 closes the Desktop Entry stream with with and removes the temporary file on write or replace errors. The new package smoke process at tools/ci_linux_package_smoke.py:122-140 always terminates, waits, and escalates to kill. The changed capture command uses the existing run_session cleanup at tools/ci_linux_capture_smoke.py:558-572. No new long-lived handlers, timers, caches, or native allocations are added.

Full details: Desktop Robustness

Explanation

The PR adds a destructive --remove-desktop action without confirmation. cli._run_desktop dispatches directly to desktop.remove() (beantester/cli.py:721-739), and desktop.remove() unconditionally calls os.unlink(target) when the entry exists (beantester/desktop.py:128-141).

Resolution

Require explicit confirmation before removing the desktop entry. Abort without calling os.unlink unless the user confirms, and provide a clearly documented non-interactive confirmation option if scripted removal is required.

Full details: Safe File Parsing

Explanation

The new Linux CI job parses bundle-scan.json with unbounded json.load(open(...)) in .github/workflows/ci.yml:852. Malformed JSON raises an uncaught JSONDecodeError, and a huge or deeply nested scan can consume excessive memory or raise parser errors. The job then also passes the same file to tools/sbom.audit_bundle, which uses unbounded json.load at tools/sbom.py:196-197. This is a changed execution path because the PR adds the Linux scan and audit steps.

Resolution

Remove the diagnostic json.load one-liner, or replace it with a bounded, exception-handled parser. Use beantester.jsonfile.load_json with OSError/ValueError handling, then validate that the result is a dict and that artifacts is a list of dicts before iterating. Apply the same bounded parser and schema validation in tools/sbom.audit_bundle; report malformed or oversized input as a controlled audit error instead of allowing a traceback or memory failure.

Full details: Clear User-Facing Text

Explanation

The new desktop-entry error paths do not provide a next action and can expose a raw exception. beantester/desktop.py:124 and :140 format exc.strerror or exc, so an OSError without strerror is shown directly. The messages only say cannot write or cannot remove; they do not tell the user how to correct permissions or retry. The non-Linux refusal at desktop.py:90 also says only that the system is not Linux. The new missing-library message in cli.py:1424-1427 does provide a clear alternative, so it is not affected.

Resolution

Replace the OSError fallback with a user-safe detail, such as an operating-system error occurred, and append actions: Check that the applications directory is writable, then run --install-desktop again and Check the file permissions, then run --remove-desktop again. Rewrite the non-Linux refusal as This option works only with the Linux package. Run the Linux package on Linux.

Full details: Scope, Duplication And Docs

Explanation

The PR changes persisted-data location without compatibility handling and does not fully document the Linux package. Base code stored frozen Linux data under ~/AppData/Local/BeanNetworkTester via paths._local_app_data(); the PR changes it to config_home()/BeanNetworkTester (beantester/paths.py:77-94). The PR also skips migration for non-Windows frozen builds (beantester/paths.py:369-374), so existing Linux frozen users can lose access to profiles, CSV files, and UI state. The description has no Breaking changes section and provides no migration or fallback. README documents the new flags and CI job, but it does not document how to unpack and launch the .tar.gz package or its ~/.config/BeanNetworkTester data location. The Unreleased changelog entry covers the window class and library error, but not the package or menu-entry behavior.

Resolution

Add a migration from the previous frozen Linux data directory (~/AppData/Local/BeanNetworkTester) to the new XDG directory, or retain a documented fallback. Add tests for existing Linux data. Add a README section that explains the archive name, extraction, launch command, supported runtime requirements, data location, and desktop-entry options. Add an Unreleased changelog entry for the Linux package and menu entry. If the path change is intentionally breaking, add a Breaking changes section to the PR description instead of relying only on code comments.

- The Linux bundle no longer carries libXau and libXdmcp: the system's libxcb, which the bundle never carries, needs both (ldd on Ubuntu 26.04 and Arch), so every system with a window has them; libbsd and libmd came only with Ubuntu 24.04's libXdmcp. libbz2 goes with the font stack: PyInstaller collects freetype's libraries before the spec drops freetype. The _bz2, _lzma and _zstd modules are left out on Linux; the program uses none of them, and the standard library imports them only when it can. Measured with a bundle built on Ubuntu 24.04: the window opens on Fedora 44 and Arch without them, and a capture by it still delays. - The menu entry is written with the person's umask instead of a fixed 0644 (CodeQL: world-readable mask). The menu needs no execute bit, and open() never sets one. - A test used a backslash inside an f-string expression, which needs Python 3.12; the project's floor is 3.10. - The bundle check's test listed what a bundle must carry from the list it checks, so a part dropped from the list dropped out of the test too (a mutation survived). The parts are written out now. - The frozen repro test expected BeanNetworkTester.exe on the Linux runner too; it now holds each system to its own command. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

The Linux bundle carries different libraries from the Windows zip, read off the bundle CI built on ubuntu-24.04 with Python 3.15: libX11, libXext, libXft, libXrender and libXss, libffi, zlib, Tcl/Tk 8.6, libpython, and pydivert's libebpfdivert.so, which carries libbpf, elfutils' libelf, Zstandard and zlib inside it. - beantester/legal.py keeps one list per build (WINDOWS_COMPONENTS, LINUX_COMPONENTS). COMPONENTS is the list of the system the program runs on, so --license reports what that copy carries; eBPFDivert reports the version the library gives. - THIRD-PARTY-NOTICES.md names each component and the build that carries it, with the LGPL rights in practice for libebpfdivert.so (a separate file that can be rebuilt from eBPFDivert's source and replaced) and a written offer for it, as for PyDivert. - licenses/ gains the copyright files Ubuntu 24.04 ships with these libraries, unchanged, and the LGPL 2.1 text libbpf is under. - tools/sbom.py writes the SBOM of either build (--platform, by default this system's); the Linux document has its own name and namespace, and the X.Org libraries a LicenseRef with its text. - The Linux build job scans its bundle with Syft and holds the registry to it, as the Windows build does.

The About window test expected WinDivert in the component list on every system; the Linux list carries eBPFDivert instead. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Inline comments:
Review comments at @beantester/desktop.py:
- Line 112: Replace the shared `target + ".tmp"` path with a unique temporary
path from `paths.temp_beside(target)` for each installation, and on failure
remove only the temporary file created by that invocation. Keep the existing
replacement flow using `target` intact.
- Around line 107-109: Update the path validation used by install() so an
executable path containing “=” is rejected before the desktop entry is written,
with a message telling the user to move the folder. Add this case to the
path-validation test while preserving existing control-character checks.

Review comments at @licenses/elfutils-copyright.txt:
- Around line 1-2: Replace the added Ubuntu package copyright notices with
notices for the source components actually embedded in the PyDivert-bundled
eBPFDivert 0.0.5 library, using the pinned component versions and their
applicable license text. Update THIRD-PARTY-NOTICES.md to document those sources
and versions; do not attribute the library to Ubuntu packages without evidence.

Review comments at @tests/test_desktop.py:
- Around line 158-159: Update the window-class assertion in the test to verify
the intended distinct class value, or explicitly reject "Tk", so it fails if
desktop.WINDOW_CLASS reverts to Tk’s shared class.

Review comments at @tools/ci_linux_package_smoke.py:
- Around line 171-172: Update the `desktop-file-validate` handling so its return
code determines whether validation failed, rather than relying on non-empty
stdout. Preserve both stdout and stderr in the validation message, with a
fallback that reports the non-zero exit code when both streams are empty, and
add a test covering that case.

# What a review of this repository has to know

## What a complete pull request looks like here

The change, the guard that catches its absence, an entry in the mutation registry when it
guards a behaviour, and the changelog lines. **A pull request that adds behaviour with no
guard is itself a finding**, and so is one that changes behaviour without touching the prose
that describes it - the READMEs describe current state, and drift there is invisible.

## Conventions (enforced by tests)

- Code, comments and docstrings are in **English**, and so are commit messages and pull
  request descriptions. This repository is public and its history is permanent: a comment or
  a message cannot be unpublished, because the commit carrying it stays. Keep local paths,
  machine names, addresses and credentials out of all of them. Quote the program - interface
  text, command output, code - and not a person: a sentence from a chat or an issue is
  somebody else's words. CI checks the mechanical half of this on every pull request.
