A 960 px window, Tools lists sized by their columns' words, and the Linux small texts by donislawdev · Pull Request #296 · donislawdev/BeanNetworkTester

donislawdev · 2026-10-27T22:56:31Z

What and why

Three commits.

1. A 960 px window, and Tools lists sized by the words they show (ca7c6e2)

Measured on real Tk, Windows and Linux (WSL, Noto Sans and DejaVu Sans): at the old
760 px window the TCP health list wanted 699 to 716 px of a 691 px table, so its last
column ("Resent") was cut off in every language. Words were cut too: the Polish
"not measured yet" in the RTT column and "needs administrator" in the state column,
and on Linux the Polish "proxy settings" and "lower layer down" in Adapters. Six columns with whole
words need 858 px, which no 760 px layout holds.

scaling.FIRST_RUN is 960 x 920 (the minimum follows it, as before). 960 still fits
a 1366 px screen at 125 %.
A geometry saved narrower by an older version is grown here and kept on its monitor
(scaling.grown_to, restored_geometry). Tk grows it by itself, but to the right,
past the monitor's edge.
widgets.make_room(table, words): a list column is at least as wide as the widest
text it can show, measured in the rows' own font plus a measured cell padding
(scaling.CELL_PAD). TCP health and Adapters declare the words from the nettools
tables (adapters.vocabulary, proxy.STATES, tcphealth.STATE_VOCABULARY), so a
new state or a new translation gets its room.
A table's empty note wraps inside the table. It is placed at its own width, and the
Polish TCP health note (907 px in 904 on Linux) was cut on both sides.
tools/ci_gui_render.py now fails a table without a sideways scrollbar whose
columns run past its edge, and a placed widget that runs past its parent, on every
surface and in every language. Each check first proves on cases made to fail that it
can tell. On the old layout it reports the TCP health list in Polish and English,
and the empty note in Polish.

2. Linux texts, and a CLI command Linux can run (be3e062)

Sockets: the note on sockets without a program says that Linux names it only to
root. Under sudo it says the rest are held from outside the system, as by another
WSL distribution or a container (measured: 14 of 14 without a program as a user on
Ubuntu 26.04, none as root; 4 under root in WSL, for which ss names no process
either).
The process example is chrome in the field hint, the "?" sheet and --help. It
is a bare name, so it finds Chrome as Windows and as Linux name it. chrome.exe found
nothing on Linux.
The shared "not available" words and --doctor on other systems name Windows and
Linux. TCP health on a Linux kernel without the socket list says so
(tcpestats.why_not).
The target field's tip no longer says it requires psutil.
Copy CLI command and the repro report on Linux. Ubuntu 26.04 has no python,
only python3, so the copied python bean_network_tester.py ... ended in "command
not found". A capture also needs root, and pydivert lives in the virtual
environment. The command is now sudo <venv python> -B bean_network_tester.py ...,
without sudo and -B for --simulate. The interpreter is named relative to the
checkout, from ~, or as python3, never by a path from the machine. Both
generated commands, pasted into a shell on an Ubuntu 26.04 machine, exit 0 as a
user and under sudo. Windows is unchanged.

3. Quoting for bash, closing sockets, an unplugged monitor, and the mutation runner (2d323b2)

Copy CLI command on Linux puts its values in single quotes (shlex.quote);
Windows keeps the cmd.exe and PowerShell quoting. Inside double quotes bash still
expands $( ), $NAME and a backtick, and at a prompt, where history expansion is
on, the ! of chrome,!chromedriver refused the line ("event not found") or
recalled an earlier command. A bare backslash was dropped too: re:\d+ arrived as
re:d+. Measured in bash in WSL: 9 of 16 values arrived changed before, none after.
A Linux-only test pastes the command into real bash with history expansion on.
Sockets: psutil gives a socket in TIME_WAIT no PID, even to root, so the note
counted it as another account's, or under sudo as held from outside the system. It
is now PID 0, as on the native path and as the help already said. A connection its
program has closed in another closing state cannot be told apart, so both Linux notes
say that a closing connection may have no program.
A narrow window saved on a monitor that has since been unplugged was grown onto the
edge of the remaining one and kept there. The saved geometry is now checked before
it grows, so the window opens in the centre, as the README says.
tools/mutate.py fails a run with any BROKEN entry other than the canary. A
--changed run reported "BROKEN: 1" and passed: one new entry was indented four
spaces too deep, and is fixed. A registry test now compiles every mutated file, so
this shows up before CI.

Checked

Lint (ruff, mypy) on every changed file.
Every new test was shown failing on the old code: the grown geometry (pure and
wiring), make_room and both panels' words, the empty note wrap, the render-check
wiring, the Sockets note per system, TCP health's own words on Linux, --doctor off
Windows and Linux, the chrome example, and the Linux command.
The edited test files and the hand-picked guards pass on Windows and on Linux (WSL).
The real-Tk render check passes in WSL in Polish, English and Chinese. On the old
product it reports the cut table.
The GUI smoke check passes.
Real-Tk shots of every surface at 960 px were taken on Windows and Linux.
The mutation registry anchors were checked. The mutations themselves run on CI.
FILE_CEILING is 1086 -> 1083, because app.py shrank and the ratchet asked for it.
Commit 3: every new test fails on the old code (the bash test in WSL, the rest on
Windows), and the edited test files pass on Windows and in WSL.
Not run locally: the full suite and mutate.py (CI).

Summary by CodeRabbit

New Features
- Linux users can run the app’s network tools, with clearer guidance for launching normal and simulated sessions.
- Process filters accept names such as chrome on both Windows and Linux.
Improvements
- Saved windows now grow to meet the minimum size and stay within their monitor when possible.
- Tool tables better accommodate localized labels, and empty-table notes wrap within the available space.
- Linux socket and TCP-health messages explain when process or connection details are unavailable.
Documentation
- Updated platform, process-filter, and command-line guidance.

- The window opens 960 px wide at 100 % (760 before) and is never made narrower. At 760 the TCP health list wanted 699 to 716 px of a 691 px table, measured on real Tk on Windows and Linux, so its last column was cut in every language. A geometry saved narrower is grown here and kept on its monitor (scaling.grown_to, restored_geometry): Tk grows it to the right, past the edge. - widgets.make_room: a list column is at least as wide as the widest word it can show (states, types, "not measured yet"), in the rows' own font plus a measured cell padding. TCP health and Adapters declare the words from the nettools tables, so a new state or translation gets room. - A table's empty note wraps inside it: placed at its own width, the Polish TCP health note was cut by the frame on both sides on Linux. - tools/ci_gui_render.py measures every table without a sideways scrollbar on every surface and fails one whose columns run past its edge, and every placed widget past its parent, after proving on cases made to fail that it can tell. On the old layout it reports the TCP health list in Polish and English. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Walkthrough

This pull request updates GUI sizing and saved-window restoration, adds checks for GUI content overflow, and extends Linux-specific capability messages and reproduction-command generation. It also updates process-name examples, localized text, tests, and documentation.

Changes: GUI layout and overflow checks

Layer / File(s)	Summary
Window sizing and restoration `beantester/gui/app.py`, `beantester/gui/scaling.py`, `tests/test_gui_helpers.py`, `tests/test_gui_layout.py`, `CHANGELOG.md`	The first-run window width increases to 960 pixels. Saved windows are grown to the minimum size and kept within their monitor when possible.
Localized table sizing and notes `beantester/gui/widgets/*`, `beantester/gui/toolbox/adapters.py`, `beantester/gui/toolbox/tcphealth.py`, `beantester/nettools/adapters.py`, `beantester/nettools/proxy.py`, `beantester/nettools/tcphealth.py`, `beantester/gui/theme.py`, `tests/test_virtual_tables.py`	Treeview columns use declared localized text to determine whether they need more width. Empty-table notes are centered and wrap at 90% of the tree width.
GUI overflow detection and validation `tools/ci_gui_render.py`, `tests/test_gui_layout.py`, `tests/test_mutation_registry.py`	The render check detects overflow in non-scrollable tables and placed widgets. It includes those findings in its pass/fail result.

Linux support and command reporting

Layer / File(s)	Summary
Linux capability and process reporting `beantester/capabilities.py`, `beantester/capture_backend.py`, `beantester/driver.py`, `beantester/nettools/sockets.py`, `beantester/tcpestats.py`, `beantester/gui/toolbox/sockets.py`, `beantester/cli.py`, `lang/*.json`, `tests/test_capabilities.py`, `tests/test_nettools_sockets.py`, `tests/test_matchers.py`	Capability text identifies Windows and Linux. Socket-owner notes vary by platform and root status, and Linux TCP health has a module-specific unavailable reason. Process examples use `chrome` without `.exe`.
Platform-aware reproduction commands `beantester/appinfo.py`, `beantester/repro.py`, `beantester/cli.py`, `README.md`, `tests/test_summary_repro_views.py`, `tests/test_cli_runtime.py`	Linux command generation selects an interpreter path and adds `sudo` and `-B` for normal runs. Simulations omit both. Reproduction commands and the missing-Tk suggestion use the simulation setting.

Full details: Tests For Changed Behavior

Explanation

PASS. The PR changes runtime behavior outside pure UI layout, and the changed tests cover it. tests/test_summary_repro_views.py covers linux_command, command_name, simulation versus capture, interpreter paths, quoting, and repro commands. tests/test_nettools_sockets.py covers platform- and privilege-specific owner notes. tests/test_capabilities.py covers Linux TCP-health capability wording, and tests/test_capture_backend.py covers the updated doctor text. tests/test_matchers.py covers the updated process examples and localized help. No test function was deleted, skipped, or weakened without justification. Geometry assertions were updated for the new window size, and new geometry and layout tests were added.

Full details: No Hardcoded Ui Styling

Explanation

PASS: The PR changes Tkinter GUI code, but it does not add hardcoded per-control styling. New sizing uses shared FIRST_RUN, CHARS, CELL_PAD, and NOTE_SHARE values. make_room measures text with the Treeview font and applies dynamic column widths through the reusable SortableTree component. The only new label option is shared alignment/wrapping behavior, and no new literal colors, fonts, font sizes, margins, paddings, or corner radii appear on individual controls.

Full details: No Obvious Performance Problems

Explanation

No clear performance problem is introduced. The new make_room work runs when the two panels are constructed and measures small, fixed vocabularies (7/10 adapter entries, 3 proxy states, and 8 TCP states). It does not process table rows or add Treeview items. The existing virtualized table remains in use. The render-check additions perform bounded widget-tree scans in the CI tool, not application polling or blocking I/O. No changed timer or refresh path performs heavier or more frequent data polling.

Full details: Desktop Robustness

Explanation

No custom-check failure is introduced. The PR changes GUI sizing, geometry validation, localized table sizing, and Linux wording/command generation. It adds no asset loading, file writes, date/culture parsing, background operation, destructive action, or network call. The Linux command uses sudo only for real capture commands, while --simulate explicitly omits sudo; the repository documents that capture requires root or equivalent capabilities. Saved geometry remains a validated in-memory transformation, and existing persistence writers are unchanged.

Full details: Safe File Parsing

Explanation

No unsafe runtime file parsing was introduced. The changed production code only builds quoted Linux command paths and sizes GUI content. Translation files remain loaded through the existing beantester.i18n.load_languages() path, which calls beantester.jsonfile.load_json() with a 4 MiB limit, rejects non-JSON constants, and converts deep nesting and memory failures to ValueError. The added json.load() calls are test-only reads of fixed repository translation files; they do not process user-controlled files or deserialize executable types.

Full details: System Changes Are Reversible

Explanation

The PR does not add or change code that modifies system state. Production changes cover GUI sizing, localized text, diagnostics, and CLI command-string generation. linux_command() only returns a string containing sudo; it does not execute commands or alter network filters, proxies, firewalls, drivers, services, registry, process hooks, or system time. Existing capture behavior is unchanged.

Full details: Clear User-Facing Text

Explanation

PASS. The PR changes user-facing examples, Linux capability notes, socket notes, and CLI guidance. The process example is consistently chrome across the CLI and all three locales. Linux-specific root/sudo wording is separate from Windows administrator wording. No new controls, vague button labels, Yes/No confirmations, or raw-exception messages were introduced. The TCP health text states the cause, and it is shown by the existing non-error unavailable-tool panel.

Full details: No Resource Leaks

Explanation

No resource leak is introduced. The changed runtime code adds no new timers, subscriptions, threads, processes, files, sockets, queues, or native allocations. make_room() creates only a local Tk font for measurement; it stores no reference and is called only while constructing the Adapters and TCP health panels. The new render-check Toplevel objects use finally: window.destroy(), and the root teardown cancels pending after() callbacks before root.destroy(). The remaining changes are geometry, text, and sizing logic.

Full details: Scope, Duplication And Docs

Explanation

The changed-file diff is coherent with the title and description. The GUI changes cover the 960 px first-run width, saved-geometry migration, table vocabulary sizing, empty-note wrapping, and related render checks. The Linux changes cover localized platform text, socket and TCP-health explanations, process-name examples, and copyable capture/simulation commands. README.md and CHANGELOG.md document the user-visible behavior, and the language files update the displayed text. The new helpers use the existing scaling, SortableTree, nettools, paths, and i18n layers; no duplicate pre-existing helper was found. command_name(simulate=False) preserves existing callers, CLI arguments and persisted geometry format remain compatible, and older saved geometries have a fallback/growth path. No unrelated significant change or undocumented breaking API/config/data-format change is evident.

Full details: No Secrets Or Debug Leftovers

Explanation

The diff adds hardcoded absolute local paths and a user-like name in tests/test_summary_repro_views.py. Lines 146 and 149–160 use /u/ana/..., /opt/py/..., /srv, and /x/...; /u/ana also embeds the user name ana. These fixtures match the custom check's forbidden local-path and user-name conditions. The added print(...) calls in tools/ci_gui_render.py are intentional render-check reporting, not leftover debug output. No credentials, private URLs, emails, or agent files were found.

Resolution

Replace the committed /u/ana, /opt/py, /srv, and /x literals with paths created at test runtime, such as pytest tmp_path/pathlib fixtures. Keep the same inside-checkout, home, outside-checkout, quoting, and missing-home assertions without embedding a user name or machine-specific absolute path.

Inline comments:
Review comments at @beantester/gui/scaling.py:
- Line 218: Validate the saved window position against the current screen bounds
before calling grown_to, so a position on a detached monitor uses the centered
fallback instead of being moved onto the primary monitor. Add a restoration test
for a detached-monitor position and verify it returns to the current screen’s
center.

Review comments at @beantester/repro.py:
- Line 159: Update the reproduction-command argument quoting so Linux commands
use POSIX-compatible quoting that prevents shell expansion, while Windows
commands continue using _quote(). Apply this in the command construction that
calls command_name(simulate).

Review comments at @lang/en.json:
- Around line 1037-1038: Update the `tools.sockets.note_no_pid_linux` and
`tools.sockets.note_no_pid_root` messages in English, Polish, and Chinese to
avoid claiming that every socket without a PID belongs to another account or an
external system. Distinguish sockets with unknown ownership from known
permission restrictions: say that `sudo` may reveal more owners and that some
sockets have no current owner.

Review comments at @tests/test_mutation_registry.py:
- Line 9795: Update the column-sizing mutation replacement so its if False
statement uses eight leading spaces, keeping the mutated code syntactically
valid and allowing the named test to reach its make_room assertions.
