- the timeline's Δ glyph became a **Details** button, and it now appears on
Update rows too (not just card-side changes); EN "Changed (card)" ->
"Changed on card", RU "Изменено (картой)" -> "Изменено картой"
- the details modal shows the affected unit — the whole file, or the single
record that changed — **before and after** the change as hex views (16 bytes
per row, ASCII column, never-observed bytes as `--`), with the bytes that
changed and the bytes the operation *first observed* highlighted in two
different colours, plus the changed/new byte counts and the APDU reference;
the old before/after byte table is gone
- `GET /api/sessions/<id>/files/image?key=…&change=…` returns those two views
(segments with offsets) plus the change's metadata; the images are
reconstructed from the current image by undoing the later changes
(`FileTracker.change_images`), so nothing is duplicated per event — every
value change is an event, hence the values are exact (a byte only first
observed later can appear as known in both views)
- tracker: change events carry `observed_ranges` (bytes that were unknown
before the operation) next to `ranges`; an update that only observes new
bytes now records an event (so it can be inspected); record-file ranges are
in-record byte offsets (the record number stays in its own field), which the
previous "record number as position" could not express for a hex highlight
- tests: change-images reconstruction (before/after per event, later changes
undone, records isolated, observation-only events, unknown gaps), the image
endpoint (200/404/400), and Node tests for the hex-image helper (highlight
classes, unknown gaps, ASCII, row limit) and the modal rendering
- v2.4.0; SW cache simtrace-analyser-v65
- new `simtrace_analyser/filetrack.py`: a single-pass tracker over a
session's decoded messages, keyed by (DF, FID) and trace-wide (resets only
wipe the per-channel selection): counters (`select`/`read`/`update`,
successful operations only), a sparse image of the observed bytes
(transparent files by offset, record files per record number) and the
change log
- changes: **device** = an UPDATE seen in the trace (applied to the image,
`no_change` flags a provable no-op); **card** = a READ whose bytes differ
from the image on bytes already known (logged at the surfacing read with
the changed ranges and the before/after hex; never-seen bytes just fill
the image, they are an observation, not a change)
- SFI-addressed accesses join the same entry as path/FID ones: the SFI ↔ FID
relations come from the normative tables and from every surfaced FCP `88`
DO (including the spec's "SFI = 5 LSBs of the FID" rule when the DO is
absent); an SFI used before its relation is learned stays provisional and
merges into the resolved entry
- the DF identity follows TS 102 221 §8.4/Table 8.2: `selected_df_fid()` now
resolves an EF path selection to its parent DF and returns `aid:<hex>` for
applications selected by an unknown AID (named from EF.DIR when the trace
surfaced it); `Database._decode_rows` gained an `on_message` hook and
`track_files()`
- `GET /api/sessions/<id>/files`: the operation timeline, the per-file
counters/coverage/change log, the SFI relations and the AID labels
- PWA: the side panel's Map/Stats tabs became a view selector (Map / Stats /
Files); the Files view is a timeline of Read / Update / Changed (card) rows
(colour-coded, the same file names as the Map view), a row click jumps to
the APDU (loading the pages it needs) and a card-change row's Δ opens the
changed ranges with the previous and the new bytes; EN/RU
- bounds: the image freezes past 64 KB of observed bytes per file, the change
log keeps the last 1000 events per file (counters keep counting)
- tests: tests/test_filetrack.py (counters, resets, channels, image/diff
semantics, record files, SFI resolution and the provisional merge, EF.DIR
labels, caps, the endpoint) and Node tests for the Files-view helpers and
wiring
- v2.3.0; MIN_SERVER_VERSION 2.3.0; SW cache simtrace-analyser-v63
- new `simtrace_analyser/comprion.py`: parses the tab-separated ISO Protocol
Layer export (metadata block, ATR/PPS exchanges, APDUs with continuation
rows, delays in etu) and re-encodes every exchange into the wire-shaped
TPDUs the analyser stores — a case-4 exchange becomes the command, a
fabricated `61 <len>` status word and a GET RESPONSE (command's logical
channel preserved), so command/response pairing, FCP/file decoding and the
GET RESPONSE filters work unchanged; Cold reset / Power off become RST/VCC
line events, deliberately without the sigrok CLK extension (the export
carries no clock measurement)
- optional matching **ISO Application Layer** export as the exact time base:
its one `Time:` row per exchange (ms precision) replaces the delay estimate
(0-based elapsed, `started = Session Name + first Time`), guarded by a
session-identity check (`Session Name`, falling back to `Working
directory`; the two layers' export timestamps differ and are not compared)
and an exchange-count check — mismatched files are refused, never mixed
- protocol-only imports keep the Delay-based timeline: card/line activity
time (host pauses absent), the unit assuming 3.8 MHz (`CLK_HZ`); the
estimate is not fed into the CLK/RST line-event annotation
- `POST /api/sessions/import?format=comprion` (raw text body, or a JSON
`{text, times_text}` bundle) with stable error codes (app_layer /
not_comprion / unsupported_layout / no_data / times_unparsable /
session_mismatch / time_base_unverified / time_base_mismatch); a COMPRION
file dropped on the PCAP path answers with a pointer (comprion_export);
session mode `comprion`, window from the Session Name
- PWA: import dialog with two separate pickers (Protocol Layer required,
Application Layer optional) whose hint switches between "activity time"
and "exact timestamps"; errors stay in the dialog with both selections
until fixed or cancelled (Cancel/Esc, also disabled while importing);
EN/RU
- tests: tests/test_comprion.py (parser, wire encoding, time base + guards,
import endpoint) and frontend/tests/comprion.test.js (file checks, slot
validation, dialog state machine with a DOM stub, RU coverage)
- v2.2.0; MIN_SERVER_VERSION 2.2.0; SW cache simtrace-analyser-v61
- terminal power supply (tag 80): voltage class per Table 6.1, maximum
current in mA, clock in 0.1 MHz steps ('FF' = not indicated)
- extended logical channels (tag 81) — zero length per §11.1.19.2.2, a
nonzero length is preserved as raw
- additional interfaces (tag 82 b1 = UICC-CLF)
- eUICC device capabilities: tag 83 per GSMA SGP.22 v2.6 §3.4.2 Table 7
(LUId/LPDd/LDSd/LUIe-SCWS); tag 84 preserved raw (no pinned SGP.32 spec)
- unknown/private TLVs preserved via raw_tlv
- concise APDU-list summary; decoded rows in the PWA detail view
- v2.1.0; SW cache simtrace-analyser-v55
- tests: 6 real samples from the local trace sessions (49/55/58/61/206/208)
- move the analysis server out of simtrace2_pysniff into simtrace_analyser;
simtrace2_pysniff stays as the simtrace2-sniff replacement capture utility
- new server CLI: simtrace-analyser-server; python -m simtrace_analyser
(simtrace2-pysniff-server and python -m simtrace2_pysniff.server dropped)
- simtrace2_pysniff lazy-imports hardware symbols, so the server no longer
pulls PyUSB at startup; the GSMTAP/PCAP codecs work without libusb
- version 2.0.0 everywhere (was 1.22.21); PWA SW cache simtrace-analyser-v54
- frontend: server name, clone URL and i18n strings updated; vendored-parser
reference otaman -> SIMple
- README/README_RUS reworked product-first (analyser first, utility second)
- DB dir ~/.simtrace-analyser, /api status payload and hosted PWA unchanged
- More precise than 'ATR STARTS' (the ATR starts after the de-assert
delay, not at the edge) while staying human-friendly; reads as a pair
with 'RESET ASSERTED'
- Update tests and both READMEs (backend-only, no version bump)
- capture.py: map GSMTAP PPS request/response (0x02/0x03) to 'pps',
matching the pcap-import mapping (was decoded as TPDU live)
- decode.py: parse the optional RST CLK extension (sigrok v1.9.0+,
payload flag bit 0); ATR gains clk_hz/data_rate/etu_us derived from
TA1 Fi/Di (data_rate = clk_hz × D / F)
- database.py: CLK state is consumed by the next ATR (no stale rate
for an ATR without preceding RST); a late-arriving RST measurement
is backfilled onto the ATR it belongs to; replay context carries
the CLK across pagination/live polling
- PWA: ATR detail shows CLK/Data rate/ETU; RST event detail shows CLK
- tests: PPS mapping, CLK parse with/without flag, rate math,
DB consume + backfill round-trips
- README/RUS updated
- Bump 1.22.18, SW cache v49->v50
- Store raw session name in STATE.currentSessionRawName
- Re-render session-name-display in toggleLang() with current translation
- Add frontend.png screenshot to README
- Bump 1.22.15, SW cache v46->v47
Follow-ups from the capture-reliability review:
- All server-side capture log lines are now prefixed with a local
timestamp (YYYY-MM-DD HH:MM:SS) for easier correlation.
- New --log-interval SECONDS CLI flag (default 60) tunes the
"Capture alive" heartbeat interval; passed through to CaptureManager.
Stays on 1.22.0 (backend-only). 369 tests pass.
The GSMTAP capture thread died silently whenever a single non-SIM or
truncated GSMTAP datagram arrived (read_packet() raises ValueError,
uncaught in the loop, killing the daemon thread while UDP kept
flowing) — matching the "stops listening after a sniffer restart"
symptom.
Fixes:
- GsmtapListener.iter_messages() now catches ValueError/struct.error
from read_packet(), drops the offending datagram (counted via a new
`dropped` counter) and keeps listening.
- CaptureManager._capture_loop() guards the DB insert so a transient
error can't kill the thread; a top-level guard logs
"ERROR: capture thread stopped on error …" + traceback and clears
the session so /api/status no longer reports a stuck "active".
- Server now logs capture liveness to stderr: "Capture started", a
periodic "Capture alive: session=N messages=M bytes=B dropped=D"
heartbeat (default every 60 s, configurable via log_interval), and
"Capture stopped" (or "empty session discarded").
Tests: +5 (listener survives non-SIM/short packet, capture loop
survives insert error, logs stop-on-error, heartbeat+stop log).
Stays on 1.22.0 (backend-only).
sigrok-iso7816-stream sets GSMTAP_FLAG_BAD_FCS (0x01) in the GSMTAP
header `res` byte on desynced TPDUs (mis-framed exchanges kept for
forensics). Propagate that flag through the whole pipeline so such
packets are explicitly surfaced instead of decoding as garbage:
- gsmtap.py: GSMTAP_FLAG_BAD_FCS const; GsmtapReceiver.read_packet()
now returns (sub_type, data, flags) from the res byte.
- server/capture.py: GsmtapListener forwards the flags to the DB.
- pcap.py: _parse_gsmtap_hdr/_scan_gsmtap/extract_gsmtap and
parse_pcap/parse_pcapng now yield a (ts, type, payload, flags)
tuple, so the flag survives a PCAP/PCAPNG round-trip.
- server/server.py: PCAP import stores the flags.
- server/decode.py: gsmtap_flag_names() maps bit 0x01 to
'bad FCS (desynced)'; merged into decoded errors for tpdu/atr/pps
and rst/vcc, so the frontend ⚠ badge + Errors row flag the entry.
User-visible: desynced TPDUs show a ⚠ "bad FCS (desynced)" marker
in the trace and detail views. Tests: +4 (decode BAD_FCS markers,
PCAP flag round-trip); existing tests updated for the new tuple
arities. Version 1.22.0, SW cache simtrace-analyser-v32.
Support the sigrok-iso7816-stream decoder (FX2 logic-analyzer passive
SIM sniffer, github.com/anttro/sigrok_iso7816_stream) which streams
GSMTAP-SIM on UDP 4729 and adds two custom sub-types for line events.
- gsmtap.py: GSMTAP_SIM_RST_EVENT (0x10) / GSMTAP_SIM_VCC_EVENT (0x11).
- capture.py: gsmtap_msg_type() maps 0x10→'rst', 0x11→'vcc' (shared by
the listener and tests); pcap.py _SUB_TYPE_NAMES gains the same
entries so PCAP re-imports of these captures preserve the events.
- decode.py: decode_line_event() decodes [direction, level, reserved]
into reset asserted/de-asserted or power applied/removed + level;
routed through decode_sniff_msg.
- database.py: reset-assert and power-removal invalidate the per-channel
file selection (card-level transition); de-assert / power-on are
markers only.
- frontend: RST/VCC labels (RESET ASSERTED / VCC OFF, …), a detail-view
branch (Event + Level + raw), and list styling (.apdu-type.rst/.vcc).
README notes the custom sub-type compatibility. Tests: +8 (line-event
vectors, sniff routing, subtype + PCAP round-trip mappings) — 359
total. Version 1.21.0, SW cache simtrace-analyser-v31.
Add simtrace2-pysniff-server CLI — HTTP API for simtrace-analyser PWA.
Two capture modes: GSMTAP UDP listener (compatible with simtrace2-sniff)
or direct SIMtrace2 hardware capture. SQLite storage with sessions +
messages tables. REST API with CORS.
server/ sub-package: database.py, capture.py, server.py, __main__.py
README updated with server usage section.
pyproject.toml: simtrace2-pysniff-server script entry added.
Use sys.stdin.isatty() to auto-detect: foreground sessions still
respond to SIGHUP (terminal close kills the process as expected),
background/piped processes ignore it and survive.
__main__.py: add signal.SIGHUP → SIG_IGN before setting up
SIGINT/SIGTERM handlers. Sniffer no longer dies when the terminal
closes or the shell session ends.
README: add Background / Daemon section with nohup examples.
Split Quick Start into Prerequisites (Python/PyUSB/libusb/hardware),
Install (clone + pip), and Running (startup script vs Python module).
Startup script section includes env var override examples.
Added dependency table note — PCAP/GSMTAP/hex dump use only stdlib.
dump.py: tpdu_timestamp_prefix(), tpdu_atr_time_prefix(),
format_message() accepts tpdu_prefix parameter,
FileDumper supports fmt + ATR time tracking
__main__.py: --format/-f flag (hex|timestamp|atr-time),
atr_time_start tracking in message loop
sniff-start.sh: pass through --format/-f and FORMAT env var
