Frontend:
- trace empty-state now shows connection status + capture mode (boxed,
colored) in the center, updated live via checkConnection
- capture-mode uses amber warning style (gsmtap/disabled), green for direct
- stopCapture clears currentSessionId
Server:
- gsmtap read_packet catches OSError on socket close (no more EBADF
traceback on stop)
- stop_session joins the loop and discards a session with zero messages;
/api/capture/stop reports discarded
- startup prints server version
Tests: 122 (gsmtap close, empty/non-empty capture lifecycle).
- pcap.py: _parse_tsresol now pads options to a 32-bit boundary
((-length) % 4) and uses 2** for the MSB-set (power-of-2) case, so
nanosecond if_tsresol is read correctly (was defaulting to µs and
scaling timestamps 1000x)
- database/server: set imported session started/ended from the first/last
packet timestamps (falling back to wall-clock for synthetic SPB)
- frontend: formatDuration renders hours
- tests: tsresol (ns after padded option, default µs, ns round-trip) and
session-window/fallback (119 total)
First published version. __version__ and pyproject bumped to 1.0.0,
/api/status now returns 'version' so the PWA can check compatibility.
Tests: 107 (status includes version, package version).
Lets a public-hosted PWA reach a local simtrace2-pysniff-server
(http://127.0.0.1:8081); without it the browser blocks the preflight
before any request is sent.
- pcap.py: parse_pcap (micro/nano, both byte orders) and parse_pcapng
(SHB byte-order, IDB linktype + if_tsresol, EPB/SPB) readers that
unwrap Ethernet/RAW/IPv4/NULL/SLL/SLL2 to UDP and extract GSMTAP-SIM
packets (APDU->tpdu, ATR->atr, PPS->pps), with a heuristic fallback
- database: insert_messages bulk-insert helper
- server: import endpoint reads raw body, auto-detects format, skips
non-GSMTAP packets; 400 'No GSMTAP data found in trace' (no session)
when empty, else creates a 'pcap' session named after the file
Tests: 102 (pcap round-trip, pcapng, no-GSMTAP, endpoint 200/400).
pcap.py: build_pcap(packets) — build PCAP bytes in memory (same format
as PcapWriter)
database.py: get_messages_raw() — raw elapsed/type/data without decode
server.py: GET /api/sessions/<id>/pcap generates a GSMTAP-encapsulated
PCAP (ATR/TPDU) with real timestamps and downloads it as
<session-name>.pcap (ASCII filename fallback + RFC 5987 UTF-8 for
spaces/unicode via _content_disposition)
tests: build_pcap + _content_disposition (67 total)
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.
