cannet v0.10.0

Opening a capture

• Fixed: a BLF written relative to capture start no longer draws
  negative times.
• Fixed: an import now keeps every frame inside the range you asked
  for.
  • Previously it stopped at the first out-of-range frame and never
    resumed.
  • On the measured file that lost 90 of 121 frames, including the two
    earliest.
• Fixed: a capture is anchored at its true earliest timestamp, not
  at whatever arrived first.
• Fixed: the import dialog shows a file's real earliest and latest
  times, not the first and last objects in file order.
• Fixed: a BLF whose writer crashed now opens. One missing trailing
  byte used to discard the whole file.
  • 16,387 frames recovered from the measured fixture; the file itself
    is never modified.
  • A system message says what was recovered, and that the absolute wall
    clock was lost.
• New: loading shows real progress — bytes scanned, then frames
  imported, then frames decoded.
• New: a Cancel button sits beside the progress bar and works during
  both load phases.
• Fixed: cancelling a large MDF import now actually stops. It used
  to keep building caches for the capture you discarded.
• Fixed: a signals-only MDF (signal data, no CAN frames) now plots.
  It used to import fine and draw nothing.
• Fixed: clearing and re-importing the same file updates the view.
  It used to leave the trace stuck showing raw epoch seconds.
• New: the channel-map dialog takes the keyboard — Enter accepts
  the defaults, Escape cancels, Tab stays inside it.
• New: an example set at examples/time-origins/ shows how each
  kind of time origin behaves.

Saving a capture

• Changed: the toolbar button reads Export and sits beside
  Import, wearing the mirror of its icon.
• Fixed: a capture interrupted mid-write now leaves a visible file
  where you asked for it, and a BLF one still opens.
• Fixed: Save Capture no longer rewrites out-of-order timestamps. A
  saved BLF now matches what was captured.
  • The measured error was 500 ms of invented delay on one frame.
• Fixed: a saved BLF's header now states the capture's true end
  time, rather than its last-appended object.
• Fixed: MDF event blocks now carry the ASAM-correct marker type.
  Files already written stay mislabelled.
• Changed: an event's colour now fills a BLF marker's label instead
  of colouring its text.
  • Other tools will draw a solid coloured block where they drew thin
    coloured glyphs.

Databases and decoding

• Fixed: a signal's enum labels now come from the database that
  actually decodes it.
• Fixed: a trace row and a plot no longer disagree about the same
  signal's value.
• New: a database assigned to no bus decodes nothing anywhere,
  instead of silently decoding every bus.
• New: unchecking a bus parks that database's caches; assigning it
  back brings the samples straight back.
• New: where two databases define one signal, you can pick which one
  wins. The pick is saved in the project.
• New: one pick also re-points every reference to a signal that was
  renamed in a newer DBC.
• Fixed: the Database panel no longer claims an unassigned database
  "applies to all buses".
• New: two databases defining the same id now warn on the losing
  row, naming which one wins.
• Fixed: a database edited on disk now reaches the plot, the
  filtered trace and the by-id view.
• Fixed: renaming a VAL_ label updates the pickers and the plot
  without reopening the view.
• Fixed: the ingest verifier no longer borrows a counter or CRC
  designation from a database that does not supply the message.
• New: a plot series from a project older than per-bus binding is
  flagged as undecoded and can be re-pointed.
• New: the Database panel groups a multiplexed message's signals by
  mux arm, named from the selector's own labels.
  • Dragging an arm plots that arm's signals in one gesture; search
    finds arms and reaches into them.
  • Single-signal arms stay flat; extended multiplexing stays a flat
    list with a note.

The signal mapping panel

• New: a View Signals panel lists every signal your open views
  reference, and what currently decodes each one.
• New: its toolbar badge counts the signals needing attention, live,
  whether or not the panel is open.
• New: filter by status or by bus, wash rows by status, and sort by
  bus.
• New: an RBS signals grid shows every field's encoder status, so an
  override the encoder dropped is visible.
• New: a drifted row — scale changed, or gone stale — carries a
  one-click Accept that adopts the database's current definition
  across every referencing view.
• New: RBS values clamp to the signal's physical range on entry,
  with out-of-range entries highlighted.
• Fixed: a hex value typed into the RBS panel goes out as raw bits,
  not as a decimal physical value.

Plots

• Fixed: a signal on a shared axis renders at its real amplitude —
  the −200 A drawn as −1.5 is gone.
  • Changed: unified mode no longer stretches each unit group to
    fill the canvas. Use per-unit or individual.
• Fixed: enum y-axis ticks are bare numbers now; the quoted label
  beside every tick is gone.
• Fixed: a 300-value enum no longer draws 300 ticks. The count
  follows the axis's height.
• Fixed: a long enum label on a lane tile is ellipsized and drawn.
  It used to be omitted entirely.
• Fixed: a plot on a stopped capture re-reads after a database
  change, instead of holding the old decode.
• New: set a plot's visible range from the palette — two numbers for
  min and max, one for a width.
• Fixed: measurement statistics over a span no longer drop a sample
  when two samples share a timestamp.
• Fixed: a long event label wraps to two lines and ellipsizes
  instead of running over its neighbours; the highlighted marker draws
  on top instead of under them.

Long names

• Fixed: long signal, message and enum names render correctly on
  sixteen surfaces instead of overflowing or being cut.
  • Names ellipsize in the middle, so two names sharing a prefix stay
    distinguishable.
  • The full name is a tooltip everywhere it is shortened.
  • One pathological name can no longer reflow a whole panel.
• New: the shipped example databases carry long names and
  44-character enum labels.

The trace and the grid views

• Fixed: clicking a signal inside an expanded row selects it instead
  of collapsing the message you were reading.
• New: disclosed signals are real rows — arrow keys, Shift+click
  ranges and drag-select all work inside them.
• Fixed: a timeline event now lands on the right trace row on an
  ordinary multi-bus capture.
  • The anchoring search assumed sorted timestamps; real captures dip
    several times a minute.
  • A marker could land on the wrong row, or be dropped with nothing
    said.
• Fixed: arrow-key navigation no longer rings the whole grid
  viewport with a browser focus outline.
• New: Space on an event row jumps to it; F2 renames it inline, in
  both the events view and the trace.
• Fixed: finishing an event rename hands the keyboard back to the
  grid. The arrow keys used to go dead.
• Fixed: an invalid palette prompt shows an inline error and stays
  open, instead of closing silently.
• New: jump the whole session to a time with Mod+T; go-to-event
  gains Mod+E.

Events

• New: an event can say what it is about — signals, messages, or
  other events, mixed in one event.
• New: event rows carry subject chips naming the message or signal
  the event points at.
• New: Shift+click a plot area with signals selected to create an
  event about exactly those signals.
• New: right-click a trace frame row to create an event about that
  message, at that frame's time.
• New: hovering or selecting an event lights up what it points at
  and fades everything else.
• New: link two events, and the pair draws its extent as a coloured
  wash while either end is hovered.
• New: events have kinds, and every view has a per-kind checklist to
  show or hide each one.
• New: each event carries an editable description and a tag; the
  events view filters on both.
• New: subjects, links, tags and descriptions survive a save and
  reopen, in both BLF and MDF.
• Fixed: a BLF full of another tool's comments now survives a
  re-save. cannet used to drop every one.
• Fixed: deleting an event removes every other event's reference to
  it, so no chip points at nothing.

Transmit and RBS

• New: Space sends a one-shot transmit row, or starts and stops a
  periodic one.
• Fixed: Space in the RBS panel enables or disables the row. It used
  to scroll the panel instead.
• New: the RBS signals list is a real grid — visible cursor,
  click-to-focus, arrow keys and Space.
• Fixed: opening a project can no longer put frames on a bus. RBS
  Run is no longer saved with the project.
• Removed: the kill switch. There is now one answer to "how do I
  stop transmitting".
• New: an RBS message row says whether it will transmit, and reads
  Muted when it cannot.
• Fixed: a counter or CRC declared in a DBC now populates the fields
  editor. The controls used to be empty.
• New: each populated field says whether it came from the DBC or
  from an override in this project.
• Fixed: a malformed CannetCounter attribute now names the text it
  choked on.
• Fixed: unassigning or reloading a database stops the RBS elements
  and periodics it was driving.
• Fixed: a transmit row's Start is no longer disabled by a
  disconnected bus, so it matches what Space...

cannet v0.9.0

Remote CAN servers

• New cannet-server: run a CAN interface on another machine and connect the GUI to it over the network — every RPC relays verbatim to the upstream interface. Replay and virtual-bus tooling moved behind a debug subcommand.
• LAN discovery via mDNS (_cannet._tcp): the GUI browses , holds the live server list host-side, and shows advertised host names.
• Servers panel: per-server rows with connect/forget/token affordances, a dedicated row for a server the host is still waiting on, and the session clock offset shown per server. The app's own sidecar never appears as a row.
• The client tracks the peer's clock across the whole session and reconciles clocks across multiple servers with the client's clock for coherent message timing.
• cannet-server ships inside every GUI bundle; standalone server archives are packaged per release platform (including a Linux-only leg).
• Added command palette action to add cannet-server location to path
• When server started with routable address, enables TLS and presents durable token a client can use to authenticate. Client is presented with server signature for trust verification.

MDF (MF4) support

• Import MDF captures: channel scan, an import dialog with a checkbox per content, and embedded DBCs that load with the capture.
• Signal-only (frameless) MF4 files import directly as signal files; DBC-decoded groups arrive as file-backed signals with provenance tracked in the signal cache.
• Coded channels keep their value tables — imported enums label their values just like DBC enums.
• Export: captures can write back out including marker/event annotations

Plotting

• Multi-select signal rows in plot panels: bulk hide/show/remove/recolor/add.
• Collapsible plot areas (persisted, with per-axis collapse); drag plot areas between plot panels.
• Selected series bolded; "hide others" for a series; hidden signal rows compact to swatch + name.
• Manual Y-range works under the normalized scale; plots recover cleanly after a DBC reload.
• Honest rendering of sparse and stale data: extrapolated stretches draw dashed and clamped to the sample grid, stale lane tiles are hatched, markers land only where a real sample exists, and a one-sample series draws as a horizontal line.
• Enum/categorical lanes: labels drawn in theme-legible ink over backing boxes, hover markers on every area (lanes included), and categorical data served by runs all the way to the live edge.
• Follow-live window width comes from the user (no self-widening), and follow-live no longer predicts past the newest frame.

Signals & filtering

• Generators: project-level regex rules derive signal attributes from names (stable colors).
• Solo filter redesigned: capture-group paging (All→1…N), checkable group subsets, captureless patterns filter flat per area, unmatched areas untouched; persists with the project.
• Undo/redo covers view edits — signals, plot areas, filters, renames, colors, columns; one gesture = one step. Actions that could impact the running system are not part of undo/redo (i.e. RBS value changes)

Capture & project workflow

• Trace-open: persistent busy feedback, cooperatively cancellable imports, and one trace-open at a time.
• Recent captures follow the project (both directions) and are reachable from the command palette.
• Added project directory concern - when a cannet project exists in a directory along with a .cannet dir, that becomes the project directory. The scratch is stored in .cannet, along with window state. In this mode, the project can be autosaved.
• Faster startup when restoring a saved capture; a forced cold pyramid rebuild announces itself and offers a way out.
• Unsaved project view state is no longer restored on next launch

UI & usability

• The DBC panel is now the Database panel; its value column covers file-backed rows.
• Theme menu: light / lighthk / dark.
• Ctrl+F focuses the current panel's find/filter box.
• Gridview: Escape leaves cell edit (and returns from row content to the grid), Shift+Up/Down extends selection, first-drive fixes.
• Assorted polish: keyboard/screen-reader affordances on trace rows, hit-target and alignment fixes, singleton-panel tab titles.

Performance & stability

• 100M+-frame BLF imports ingest, decode, and plot more smoothly, though still with some brief periods of interactivity
• Smarter signal cache: per-signal caches which should be dependent on message + scaling details to avoid expensive signal cache rebuilds which occasionally happened
• Fixes: multiplexed-signal decode, sidecar readiness race on connect, PCAN debug-logging throughput, plus many small stability and performance improvements throughout.
