    +О проекте

    +

    Проект — библиотека C++17 для разбора DBC, декодирования CAN-кадров и построения дерева метаданных.

    +
      +
    • core/ — библиотека без зависимости от Qt.
      • +
    • qt/ — необязательный адаптер для Qt.
      • +
    • tests/ — тесты парсера, декодера, метаданных и дерева.
      • +
    • examples/ — примеры использования.
      • +
    +

    Сборка выполняется через qmake. Qt-зависимые цели требуют Qt 6.8.2.

    +

    +Формат задания

    +
      +
    • В начальном сообщении с заданием первая непустая строка перед пустой строкой — точное название issue в Gitea и требуемое название чата. Описание задания начинается после этой пустой строки.
      • +
    • Для названия чата используй первую строку дословно: сохраняй язык, формулировку и номер issue (#20 и т. п.). Не переводи, не перефразируй, не добавляй описание задания, план работы или итоги.
      • +
    • Например, для сообщения Support signal value descriptions #20, за которым следуют пустая строка и описание, название чата должно быть ровно Support signal value descriptions #20.
      • +
    • Применяй это правило при создании или переименовании чата, если интерфейс предоставляет такую возможность. Если управление названием недоступно, не утверждай, что чат переименован: инструкции в AGENTS.md сами по себе не управляют автоматическим названием в интерфейсе.
      • +
    • Последующие уточнения и сообщения в текущем чате не меняют выбранное название, если пользователь явно не попросил его изменить.
      • +
    +

    +Правила кода

    +
      +
    • Используй TypeFactory везде, где это уместно.
      • +
    • Не используй auto как возвращаемый тип функций.
      • +
    • Не используй lambda.
      • +
    • Придерживайся KISS.
      • +
    • Пиши читаемый код, который легко понять.
      • +
    • Соблюдай существующий стиль и настройки .clang-format.
      • +
    • Сохраняй независимость core/ от Qt.
      • +
    +

    +Тестирование

    +
      +
    • Добавляй необходимые тесты для изменённого поведения.
      • +
    • При исправлении ошибки добавляй тест, воспроизводящий её.
      • +
    • Подключай новые тестовые файлы к соответствующей цели qmake.
      • +
    • Перед завершением работы запускай применимые тесты.
      • +
    • Если проверку выполнить невозможно, сообщи причину.
      • +
    +

    Основная сборка и тесты из корня репозитория:

    cd build
    +
    qmake6 ../dbc.pro
    +

    The core library uses C++17 and has no Qt dependency. Qt integration targets the installed Qt 6.8.2, which is the only supported Qt version. Qt Core and Qt Test are used by the regression tests; model tests also link QtGui for graphical metatypes. The optional adapter requires only Qt Core. Live CAN acquisition, trace-file readers, are left to the consuming application. An optional Qt Core model adapter is provided in qt/.

    See changelog.md for the release and development history, tests/README.md for test instructions, and generated API documentation for the API reference.

      The UI tree contains three node types:

      -

      The tree supports browsing through the optional DbcTreeModel adapter.

      +

      The tree is independent of Qt and supports browsing through the optional DbcTreeModel adapter. GetParent() returns a non-owning parent pointer; GetRow() returns the zero-based sibling position (zero for a detached node or root). GetChild() returns nullptr outside the child range, and AddChild() ignores null children. Appending children preserves existing addresses and rows.

      +

      Nodes cannot be copied or moved. Transfer their std::unique_ptr ownership to preserve parent links and addresses. AddChild() accepts an rvalue ownership handle and rejects self/ancestor insertion and already-attached children with std::invalid_argument before consuming ownership. There is no detach or reparent operation; callers must supply exclusive ownership.

      +

      GetFrameKey() returns std::optional<FrameKey> for frame nodes and signals directly attached to a frame. GetSignalKey() returns std::optional<SignalKey> for those signals. Roots, detached signals, and signals without a frame parent have no key. Keys use normalized CAN ID plus standard/extended type, and signal keys also include the signal name. They match runtime definition keys, remain independent of row order and frame display names, and survive source-database changes or destruction. Renaming a signal changes its logical identity. Returned keys are values and may be retained after destroying the tree.

      It is not the primary runtime decode structure.

    Raw value representation and precision

    DecodedSignalValue::rawValue is a C++17 std::variant<std::int64_t, std::uint64_t>. For a valid signal, signed definitions produce the int64_t alternative and unsigned definitions produce the uint64_t alternative. Raw values remain exact across their full 64-bit ranges. Check valid before using the physical value. Raw data is also available when status == PhysicalConversionFailed; other invalid results have no decoded numeric data.

    This replaces the previous int64_t field: consumers that read or print rawValue directly must handle the variant.

    Physical conversion uses the active numeric type: physicalValue = static_cast<double>(raw) * factor + offset. physicalValue remains a double and is approximate for large integers. On usual IEEE 754 binary64 implementations, integers are exactly representable through 2^53; above that, some integers round to the same floating-point value. For example, unsigned UINT64_MAX remains exact in rawValue, but converts to approximately 18446744073709551616 in binary64 before scaling. Use rawValue whenever exact integer values are required.

    valid means a matching frame definition was found. Check each signal's valid separately: insufficient payload data can leave individual signals invalid even when the frame is valid. An unknown or ambiguous frame returns valid == false, a null definition, its requested key, and an empty signal list. A successful PGN match uses the DBC definition key for the frame and its signals.

    FrameDecodeStatus summarizes the result:

    - + - + - + + +
    Status Meaning
    UnknownFrame No definition matches both CAN ID and standard/extended type
    UnknownFrame No exact CAN ID/type match or eligible PGN match
    InsufficientPayload Actual byte count is less than the declared dlc
    AmbiguousFrame No exact match and multiple J1939 definitions share the PGN
    SignalErrors Payload is long enough, but at least one signal failed
    InsufficientPayload Actual byte count is less than the declared dlc
    SignalErrors Payload is long enough, but at least one signal failed
    Valid Payload is long enough and every signal is valid or inactive

    Short-payload status takes precedence over signal errors; inspect each signal's status for the individual cause. valid retains its existing meaning of a matched definition and does not imply status == FrameDecodeStatus::Valid.

    Payload policy uses dlc as a byte count, including for CAN FD; it is not the encoded wire DLC. A shorter payload is never padded: all signals whose bytes are available still decode, even if other signals fail. A longer payload is accepted; bytes beyond dlc are ignored. Signal bit layouts must fit the declared dlc, so extra bytes cannot rescue an invalid definition. Empty payloads and zero-byte frame definitions follow the same rules. Results include every signal in definition order, preserving successful values and definition handles on partial failures.

    The decoder applies factor and offset; it does not clamp physical values to the declared minimum and maximum. Non-finite conversion results (NaN or positive/ negative infinity), including overflow with finite factor/offset, produce PhysicalConversionFailed. The exact raw value and non-finite physicalValue remain available, while signal valid is false. Non-finite numeric parameters are rejected during database construction. Finite parameters can still overflow during conversion; conversion failure of a selector does not prevent raw branch selection.

    +

    Definition ownership and reload

    DecodedFrameValue::definition and DecodedSignalValue::definition are owning std::shared_ptr<const ...> handles. Each handle retains the immutable runtime snapshot. Definitions remain valid until the last database copy, lookup handle, or decoded result owning that snapshot is released. An independently copied signal result retains its definition even after the parent frame result is removed. Copying or moving results preserves ownership.

    Reload by assigning a newly built database. Stored results continue to describe the old DBC, including its units, scaling, comments, and VAL_ descriptions; subsequent decoding uses the new DBC. Removed definitions cannot be found in the new database, but old results safely retain their old definitions. Keeping even one signal handle retains the whole old snapshot; release stored results when that metadata is no longer needed.

    GetFrames() is a borrowed view. References, iterators, and raw pointers obtained from it or from a handle's .get() do not retain ownership. Keep an owning handle or an unchanged database copy while using them. Constructor input is copied and may be changed independently afterward. The raw string pointer from GetValueDescription() follows the same rule: keep the signal definition handle alive while using the string.

    Parsed DbcDatabase/FrameInfo/SignalInfo remain ordinary mutable value containers: borrowed pointers follow standard vector invalidation rules. Builders copy their metadata, so parsed input may be changed or destroyed after building. Tree nodes own metadata copies; the Qt model owns its tree and invalidates model indexes on reset. Runtime handles do not depend on the parsed database or tree. Synchronize replacement of a shared database variable with decoding; immutable snapshots do not make concurrent assignment to the same object safe.

    DecodedFrameValue::key is a FrameKey (normalized canId, isExtended), also available through DecodeFrame::GetKey(). DecodedSignalValue::key is a SignalKey (frame key, exact case-sensitive signal name). Both are value types with equality and hashers (FrameKeyHasher, SignalKeyHasher) for application maps and saved selections. Construct the same keys from parsed metadata when needed; do not use addresses or vector positions as identifiers.

Construct the same keys from parsed metadata when needed; do not use addresses or vector positions as identifiers.

    Keys stay equal across reloads and reordering when their components stay equal. Frame renaming and changes to units, bit layout, scaling, or descriptions do not change a key. Changing a CAN ID/frame type or renaming a signal produces a new key. The same name in different frames and standard/extended frames with the same numeric CAN ID remain distinct. Keys identify definitions within one logical DBC database; applications combining databases must add their own database ID. A key is not a version identifier: matching keys in different snapshots may have different metadata. Use valid/the definition handle to distinguish a matched result; default keys alone do not indicate successful decoding.

Integer/HEX values use decimal signed 64-bit numbers; floating values are finite and locale independent. ENUM assignments use zero-based indices; defaults accept an index or a quoted label.

    Definitions, defaults, assignments, and frame/signal declarations may appear in any order. Defaults apply to every object of the defined scope; explicit values override them, with the last repeated assignment winning. Duplicate definitions or defaults, undefined names, wrong types/scopes, out-of-range values, and missing frame/signal targets produce Error / InvalidAttribute at the source line.

    +

    DbcDatabase::attributeDefinitions retains types, ranges, enum labels, and defaults; attributeAssignments retains explicit values and targets. Effective values are available in attributes on the database, frames and signals. Node/environment assignments are retained by name without checking declarations; their defaults remain on the definitions. Frame/signal attributes are copied into runtime snapshots and tree payloads. Other valid attributes remain available as metadata without changing decoding.

    +

    FrameInfo and DecodeFrame expose optional frameFormat (the enum label) and cycleTimeMs (GenMsgCycleTime, unsigned 32-bit milliseconds). Missing values remain unset; zero cycle time means unspecified. StandardCAN and ExtendedCAN are recognized. Other format labels, including CAN FD and J1939PG, are preserved with Warning / UnsupportedAttribute when effective on a frame. A supported format conflicting with the encoded BO_ ID also warns. Warnings identify the assignment or default line. Attributes do not change CAN ID normalization or automatically enable CAN FD or J1939 decoding; J1939 still requires parser opt-in. Use ParseFileWithDiagnostics() to review these warnings.

A quoted unit (which may be empty) and a nonempty comma-separated receiver list are required. Unexpected trailing fields are rejected.

    The current logic is simplified J1939 extraction:

    +

    +J1939 Opt-in and PGN Lookup

    +

    Extended CAN identifiers do not imply J1939. The default parser leaves hasPgn false and pgn zero, and decoding uses exact normalized CAN ID and frame type. Enable J1939 interpretation explicitly for a file:

    +
    DbcParserOptions options;
    +
    options.enableJ1939 = true;
    +
    const DbcDatabase parsed = DbcParser(options).ParseFile("vehicle.dbc");

    +
    DbcDatabase
    Parsed DBC content stored in a simple internal form.
    Definition dbc_database.h:22
    + + +

    Both parser entry points honor this option. Standard frames remain ordinary CAN. For mixed-protocol files, parse with the default options, then set hasPgn = true and pgn = ExtractJ1939Pgn(frame.canId) (from j1939.h) only on known J1939 extended definitions before building the runtime snapshot. The same explicit metadata enables J1939 for manually constructed DecodeFrame definitions. Runtime construction rejects hasPgn on standard frames or an inconsistent PGN. No DBC attribute automatically enables J1939 interpretation.

    +

    PGN extraction retains both data-page bits (CAN ID bits 25–24) and PF:

      -
    • pf
      • -
    • ps
      • -
    • dp
      • +
    • PDU1 (PF < 240): PS is the destination address and is zeroed in the PGN.
      • +
    • PDU2 (PF >= 240): PS is the group extension and remains part of the PGN.
      • +
    • Priority and source address are excluded in both cases. This follows the Linux J1939 PGN layout.
    -

    This is enough for a practical start but should not be treated as full J1939 validation.

    +

    DecodeDatabase::FindFrame(FrameKey) stays an exact lookup. FindFrameByPgn(pgn) returns a PgnLookupResult with an owning definition handle for one eligible definition. No match returns a null handle with ambiguous == false; multiple definitions return a null handle with ambiguous == true. Copies and returned handles retain the immutable snapshot.

    +

    DbcDecoder::FindFrame and both Decode overloads first try the exact ID/type. Only when that fails for a valid normalized extended ID do they try PGN lookup among definitions with hasPgn == true. A unique PGN can therefore match a changed source address or priority, and for PDU1 a changed destination address. A changed PDU2 group extension does not match. Exact matches win even when the PGN is ambiguous, including exact matches to ordinary extended CAN definitions. Multiple PGN candidates are never resolved by order, source, or payload: FindFrame returns null and Decode returns AmbiguousFrame without decoding signals or validating the selection. Missing candidates return UnknownFrame.

    +

    On success, decoded frame/signal keys belong to the matched DBC definition; selected-signal decoding also expects those definition keys. Keep the input RawCanFrame if the received address/ID is needed separately. This feature does not implement transport-protocol reassembly, address claiming, or full J1939 validation.

    Horizontal DisplayRole headers describe these columns; other header requests return invalid QVariant. ToolTipRole returns the comment on every column. Custom roles also apply on every column; inapplicable roles return invalid QVariant:

    -

    +

    Each statement must occupy one physical line, contain at least one integer/text pair, and end with a semicolon. Spaces and tabs are accepted between fields; descriptions may contain whitespace, semicolons, and empty text. Inside quoted text, escape a quote or a backslash with a preceding backslash; other escapes are rejected. Keys are decimal integers in INT64_MIN..UINT64_MAX, with an optional minus sign; plus signs, fractions, hexadecimal numbers, exponents, and overflow are rejected. Keys never pass through double.

    +

    VAL_ may appear before or after its frame and signal declarations. References are resolved after reading the file using the same CAN ID normalization as BO_, including bit 31 for extended identifiers. Standard and extended frames with the same normalized ID remain distinct. Missing or ambiguous references, malformed statements, and duplicate integer keys produce path:line: description errors at the originating VAL_ line. Distinct keys from multiple statements are merged; 0, 00, and -0 are the same key. Keys need not fit the referenced signal's bit width or signedness; unreachable keys simply cannot match a decode.

    +

    Mappings are available as SignalInfo::valueDescriptions and DecodeSignal::valueDescriptions, and survive both database builders, including TreeNode::GetSignal(). Consumers can look up a decoded result directly:

    +
    const DecodedSignalValue &value = decodedFrame.signals.at(0);
    +
    if (const std::string *description = value.GetValueDescription()) {
    +
    std::cout << *description;
    +
    }
    +
    DecodedSignalValue::GetValueDescription
    const std::string * GetValueDescription() const
    Definition dbc_decoder.h:63
    +

    GetValueDescription() uses the exact raw integer before factor/offset scaling. It returns nullptr for an invalid decode or an unknown value; numeric decoding and physicalValue are unchanged. A mapped empty string returns a non-null pointer. The pointer belongs to the signal definition and stays valid while that definition remains alive. A decoded signal owns its immutable definition across reload.

    +

    For metadata or standalone raw values, use FindValueDescription(signal.valueDescriptions, rawValue), where rawValue is RawSignalValue (std::variant<std::int64_t, std::uint64_t>). The helper matches nonnegative signed and unsigned values identically and keeps negative values distinct from large unsigned values. Stored keys use negative int64_t and nonnegative uint64_t; when constructing mappings manually, normalize keys with NormalizeValueKey() before insertion.

    +

    Named VAL_TABLE_ tables, environment-variable mappings, multiline statements, are outside this implementation; the optional Qt adapter exposes signal mappings.

    +
    +

    +Current Limitations

    +

    This is still a minimal implementation.

    +

    Not supported yet:

    +
      +
    • extended and nested multiplexing (SG_MUL_VAL_, mNM)
      • +
    • named VAL_TABLE_ tables and environment-variable value descriptions
      • +
    • attribute relation forms (BA_REL_, BA_DEF_REL_)
      • +
    • SIG_VALTYPE_ floating-point signal types
      • +
    • signal types/references (SGTYPE_, SIG_TYPE_REF_) and environment variables
      • +
    • advanced comment handling
      • +
    • full DBC grammar coverage
      • +
    • full J1939 validation
      • +
    • extensive edge-case handling for unusual DBC formatting
      • +
    +

    Additional behavior to account for:

    +
      +
    • unregistered DBC keywords are skipped with warnings in the diagnostic API
      • +
    • an SG_ statement before the first frame is rejected
      • +
    • duplicate frame keys (normalized CAN ID and frame type) and repeated signal names within a frame are rejected at their definition lines; manually created databases are also checked for ambiguous VAL_ references during resolution
      • +
    • payload lengths are checked against storage bounds (0..255), rather than CAN or CAN FD protocol limits
      • +
    • comment handling is limited to frame and signal comments; references resolve after definitions are read
      • +
    +

    Motorola extraction uses DBC sawtooth numbering: a start bit of 7 traverses 7..0, 15..8, 23..16. Regression tests cover aligned and unaligned signals, byte boundaries, and 64-bit values.

    +
    +

    +Recommended Next Steps

    +

    A practical development order would be:

    +

    +Stage 1 - already implemented

    +
      +
    • BO_
      • +
    • SG_
      • +
    • CM_
      • +
    • VAL_ signal value descriptions
      • +
    • normalized CAN ID
      • +
    • isExtended
      • +
    • transmitter
      • +
    • receivers
      • +
    • comments
      • +
    • tree representation
      • +
    • runtime decode database
      • +
    • runtime decoder
      • +
    +

    +Stage 2

    +

    Recommended additions:

    +
      +
    • selective decoding of only chosen signals
      • +
    +

    +Stage 3

    +

    Recommended additions:

    +
      +
    • basic multiplexing (implemented)
      • +
    • attribute parsing (implemented for definitions, defaults and values)
      • +
    • richer J1939 support
      • +
    • CSV export of decoded traces
      • +
    • optimized filtering and signal selection
      • +
    +

    +Stage 4

    +

    Advanced functionality:

    +
      +
    • live plot integration
      • +
    • signal subscriptions
      • +
    • per-signal trace decode pipelines
      • +
    • decoder-assisted export formats
      • +
    +
    +

    +Build Integration

    +

    The repository supplies qmake projects. A C++17 compiler is required; the root build also requires Qt Core and Qt Test development packages. Other build systems can compile the sources listed in core/core_files.pri; no CMake configuration is currently provided.

    +

    Qt-dependent qmake targets share qt/qt_version.pri, which rejects Qt versions other than 6.8.2. The core library remains independent of Qt libraries.

    +

    Open dbc.pro in Qt Creator to see two subprojects: core and tests. core/core.pro builds the C++17 static library dbc_core without a Qt dependency. tests/tests.pro builds the QtTest executable dbc_tests and links that library. The root project declares tests.depends = core for parallel builds.

    +

    Build out of source with Qt 6.8.2:

    +
    mkdir build
    +
    cd build
    +
    qmake6 ../dbc.pro
    +
    make -j
    +
    make check
    +

    core/core_files.pri lists the library sources and headers. Consumers include core/core.pri for include paths and library linkage; the test source lists live in tests/parser_tests.pri and tests/decoder_tests.pri. When building a consumer separately, pass DBC_CORE_BUILD_DIR=/absolute/path/to/build/core to qmake.

    +

    +Build core without Qt libraries

    +

    From the repository root:

    +
    mkdir -p build/core
    +
    cd build/core
    +
    qmake6 ../../core/core.pro
    +
    make -j
    +

    qmake is still the build tool; this target does not link Qt libraries.

    +

    +Optional Qt model adapter

    +

    The adapter and its QAbstractItemModelTester suite use Qt 6.8.2. The adapter itself links only Qt Core.

    +

    The model test executable additionally links QtGui and uses QGuiApplication so QAbstractItemModelTester can resolve graphical metatypes such as QPixmap. It defaults to the offscreen platform when QT_QPA_PLATFORM is unset or empty; no display server is required. An explicit platform setting is preserved.

    +

    Enable its library and focused QtTest suite:

    +
    mkdir -p build-qt
    +
    cd build-qt
    +
    qmake6 ../dbc.pro CONFIG+=dbc_qt
    +
    make -j
    +
    make check
    +

    Consumers include qt/qt.pri instead of core/core.pri, and set DBC_CORE_BUILD_DIR and DBC_QT_BUILD_DIR to the corresponding library build directories when building separately. A widget application also needs QT += widgets. The adapter integration enables no_keywords, because core metadata has a signals member; use Q_SIGNALS, Q_SLOTS, and Q_EMIT in consuming Qt classes.

    Definition dbc_tree_model.cpp:27
    +

    The root is invisible: frames are top-level rows, signals are their children. Only column zero has children. parent() always returns column zero. The model takes exclusive ownership of the tree; do not retain mutable aliases. Metadata is copied by the tree builder, so the parsed database may be destroyed. TreeNode::GetParent() is non-owning and GetRow() gives the zero-based sibling position (zero for a detached node/root). Nodes cannot be copied or moved; transferring their unique_ptr ownership preserves addresses and navigation.

    +

    Call SetTree() on the model's thread. It accepts a detached Root or nullptr, uses beginResetModel()/endResetModel(), and destroys the previous tree during reset. All ordinary QModelIndex values expire on reset and must not be reused; QPersistentModelIndex values are invalidated by Qt. Destroying the model also invalidates indexes. Invalid and foreign indexes return no data/flags/children. Valid items are enabled and selectable, with no editing support.

It verifies all supported metadata in both builders, standard and extended frames sharing a numeric ID, empty databases, comments, and replacement with another fixture or an empty database.

    +

    +Code review and additional checks

    +

    Attribute numeric parsing shares one locale-independent converter for integer and floating-point values. Default application skips unrelated scopes, CAN ID normalization uses the validated identifier mask, and signal layout validation owns the length checks. Statement handlers continue to use TypeFactory. Core, adapter, example, and test C++ sources use explicit return types and contain no lambdas. Public metadata and parser-state comments use Doxygen descriptions.

    See tests/README.md for attribute boundary regressions, sanitizer commands, and the latest validation results.

                • +
              • Add indexed PGN lookup with PDU1 destination exclusion, PDU2 group extension, and both data-page bits. Decoder exact-ID matches take precedence; otherwise one J1939 PGN candidate is accepted and multiple candidates return AmbiguousFrame. Result and selection keys identify the DBC definition.

              Changed

              • Moved DBC statement parsing into TypeFactory-registered handlers for BO_, SG_, and CM_, with a shared parse context and keyword dispatcher. Added tests for dispatch and handler replacement, and documented how to register additional handlers. (88b5883, #4)
              • API change: DecodedSignalValue::rawValue now uses std::variant<std::int64_t, std::uint64_t> instead of int64_t. Consumers must handle the appropriate variant alternative. Physical values remain double and may lose precision for large integers. (69074e3, #2)
              -

              Fixed

              • Corrected Motorola signal extraction within bytes and across byte boundaries using DBC sawtooth bit numbering. Added decoder regression tests and build instructions; introduced the TypeFactory utility. (2c057b6)
              • Preserved the full unsigned 64-bit raw-value range, including values above INT64_MAX, and updated physical conversion and demo output. Added tests for signed and unsigned boundaries and numeric output. (69074e3, #2)
              • Validated BO_ frame syntax, CAN identifiers, payload lengths, numeric overflow, and unexpected trailing fields. Parsing errors now include the file path and physical line number. Added parser regression tests. (3bd9339, #3)

              Decoder coverage

              Coverage includes Motorola bit numbering within and across bytes, unaligned signals, signed values, scaling, 64-bit extraction, signed/unsigned boundary values (including INT64_MIN, INT64_MAX, and UINT64_MAX), numeric output, invalid lengths, insufficient payloads, and Intel regression cases. Frame validity means the definition was found; frame status reports unknown frames, short payloads, and signal errors. Tests exercise empty/short/exact/long payloads, ignored trailing bytes, signals outside declared DLC, invalid enum metadata and overflowing start bits rejected at construction, and preservation of successful signals on partial payloads. Physical conversion checks cover NaN/Inf parameters rejected at construction, multiplication/addition overflow, finite limits, signed/unsigned raw retention, and raw selector activation after physical conversion failure.

              Parser coverage

              -

              Structured diagnostic tests cover severity, code, supplied path, and physical line numbers for skipped syntax and immediate/deferred errors; warnings preceding an error are retained, and failed parses return an empty database. Common headers and namespace symbol lists stay quiet. Tests also check file-open errors, fresh parse sessions, and compatibility with the legacy throwing API. The diagnostic audit also covers 15 unsupported-statement variants, all namespace termination forms, CRLF and missing final newlines, relative paths with spaces, first-error stopping, deferred diagnostic ordering, duplicate definitions/values, selector ranges, overlaps, and preservation of supported decoding and metadata. On Linux, reading a directory exercises the distinct FileReadError path.

              -

              Parser tests cover standard and extended CAN IDs, whitespace, payload storage boundaries, missing fields, malformed and overflowing numbers, reserved ID bits, error paths and line numbers, and integration with signals and comments. Duplicate definitions are rejected at their source lines, including equivalent extended ID encodings and repeated signal names within a frame. Standard and extended frames may share a numeric ID, and separate frames may reuse signal names. Signal tests cover complete syntax and numeric validation, scientific notation, finite physical parameters and ordered ranges, spaces and tabs, receiver lists, unsupported multiplexing, and Intel/Motorola declared-payload boundaries. Value-description tests cover full VAL_ syntax, whitespace, escaped quotes, empty text, exact integer boundaries, duplicate keys within and across statements, deferred and normalized frame references, missing targets, error locations, raw lookup with scaling, unknown/invalid values, and both database builders. Temporary DBC fixtures are created in the system temporary directory and removed automatically.

              Parser tests cover standard and extended CAN IDs, whitespace, payload storage boundaries, missing fields, malformed and overflowing numbers, reserved ID bits, error paths and line numbers, and integration with signals and comments. Comment regressions cover tabs, escaped quotes/backslashes, multiline text with blank lines and indentation, CRLF, missing final newlines, comments preceding frame/signal definitions, last-wins and empty overwrites, normalized ID boundaries, standard/extended separation, malformed syntax/IDs, and missing targets. Errors verify both structured diagnostics and the throwing API at the starting line. Duplicate definitions are rejected at their source lines, including equivalent extended ID encodings and repeated signal names within a frame. Standard and extended frames may share a numeric ID, and separate frames may reuse signal names. Signal tests cover complete syntax and numeric validation, scientific notation, finite physical parameters and ordered ranges, spaces and tabs, receiver lists, unsupported multiplexing, and Intel/Motorola declared-payload boundaries. Physical-number tests apply a custom comma-decimal C++ locale and an available named comma-decimal C numeric locale. They check all four physical fields, leading signs, fractions, scientific notation, finite boundaries, zero, malformed numbers, comma/grouped numbers, overflow/underflow, and reversed ranges. Locale changes are restored after each test. The named C locale case skips if none of the supported locale names are installed; the custom C++ locale case always runs. On Linux with locale sources and localedef, run both cases without installing a system locale:

              tree_node_test.cpp is a standalone C++17 executable without Qt; see the root README for its compiler command. It is also built as dbc_tree_tests and run by qmake's make check, without Qt linkage. It checks empty trees, parent/child round trips, sibling positions, const/mutable bounds, null children, vector growth, and unique_ptr transfer. Compile-time checks reject node copying and movement. Self/ancestor insertion must throw without consuming ownership or changing links. Key tests cover frame/signal identity, standard/extended separation, repeated signal names across frames, missing keys, source replacement, and row-independent identity.

              Enable CONFIG+=dbc_qt in the root qmake invocation to build dbc_qt and dbc_model_tests alongside existing tests. Qt 6.8.2 is required. make check runs all suites. Model tests parse a temporary DBC fixture and use QAbstractItemModelTester, verify navigation across columns, invalid/foreign indexes, metadata and exact VAL_ integers, and persistent-index invalidation when reloading or clearing the tree. Their QGuiApplication registers graphical metatypes used by QAbstractItemModelTester, avoiding the invalid QPixmap type warning in Qt 6.8.2. The test executable defaults to QT_QPA_PLATFORM=offscreen when the variable is unset or empty, so no display server is needed. An explicit platform setting is preserved.

              Basic multiplexing coverage includes selector declarations after branches, Intel/Motorola branch overlap, signed active values and VAL_ lookup, unconditional signals, inactive branches, missing selector/branch payloads, exact UINT64_MAX selector matching, malformed runtime selectors, source locations, and rejection of invalid markers, selector references/ranges, overlaps, and SG_MUL_VAL_.

              Additional regression coverage

              dbc_coverage_test.cpp runs as part of dbc_tests. It covers signed boundaries below 64 bits, deterministic extraction comparisons for both byte orders across lengths 1–64, frame lookup failures, exact decode statuses, construction rejection of malformed runtime multiplexing, PGN boundaries, comment handling, file formatting, metadata copying and source lifetime, physical conversion, and TypeFactory registration/creation. Direct resolver tests construct ambiguous databases through the public metadata API, verify source locations, and check that ambiguous targets receive no values.

              +

              J1939 regressions in dbc_coverage_test.cpp verify explicit parser opt-in and ordinary extended CAN defaults, PF 239/240 and all data-page combinations, PGN zero, PDU1 destination exclusion, PDU2 group-extension matching, changed source and priority, standard/invalid-ID exclusion, and inconsistent manual metadata. They also cover exact-ID precedence, order-independent ambiguous PGNs for both PDU formats, mixed ordinary/J1939 definitions, selected-signal definition keys, raw/physical values, and owning PGN handles across snapshot replacement. The pipeline fixture explicitly enables J1939 through the diagnostic parser API. Verified in build/ with qmake6 ../dbc.pro, make -j4, and make check: all six QtTest suites and the Qt-free tree target passed. The existing named comma-decimal C locale regression skipped because that locale is not installed.

              All QtTest targets use Qt 6.8.2 and QVERIFY_THROWS_EXCEPTION. Exception tests explicitly discard nodiscard results when only the exception is being checked. The standalone tree test requires only a C++17 compiler.

              Definition lifetime and reload coverage

              dbc_lifetime_test.cpp checks retained definitions and value-description strings across reload, clear, and destruction; independently saved signal results; copied/moved results and database copies; owning lookup handles; and release of the old snapshot after its final owner is removed. Compile-time checks enforce const access to runtime metadata. Reload fixtures change ordering, frame names, scaling, units, and descriptions, remove definitions, and rename signals.

              Key tests check equality and hashing, standard/extended separation, the same signal name in different frames, and missing lookups. Constructor tests reject duplicate runtime keys, including manually supplied parsed metadata. Failed reload leaves the active database intact; empty reload clears it. Invalid/unknown results and insufficient payloads retain their documented ownership and status behavior. Inactive branches and unavailable selectors also retain definitions across reload.

              Database validation coverage

              -

              dbc_validation_test.cpp checks direct construction and manually assembled DbcDatabase input to DbcDecodeBuilder: standard/extended CAN ID limits, encoded/reserved ID bits, duplicate keys, lengths 0/1–64/65/UINT32_MAX, Intel/Motorola payload boundaries and overflowing start bits, invalid enums, NaN and both infinities in every numeric parameter, and reversed physical ranges. Selector tests include missing, duplicate, and signed selectors, branch ranges, UINT64_MAX selection, mixed-order overlaps, and exclusive branches sharing bits. Valid definitions cover the full byte-count storage range, including zero-byte frames without signals and 255-byte frames. Existing extraction tests cover lengths 1–64. Snapshot tests mutate retained frame, signal, and description aliases after rvalue construction, and verify unchanged lookups and metadata. Failed constructor/builder replacement preserves the active snapshot; clear removes its index while saved handles remain alive.

              +

              dbc_validation_test.cpp checks direct construction and manually assembled DbcDatabase input to DbcDecodeBuilder: standard/extended CAN ID limits, encoded/reserved ID bits, duplicate keys, lengths 0/1–64/65/UINT32_MAX, Intel/Motorola payload boundaries and overflowing start bits, invalid enums, NaN and both infinities in every numeric parameter, and reversed physical ranges.

              Layout validation is also compared with independent DBC bit traversal for every start position through one byte beyond payload sizes 0, 1, 8, 64, and 255, and all lengths 1–64, for both byte orders. Zero/65-bit lengths and uint32 maximum inputs are rejected. Builder snapshots survive input mutation and destruction; failed replacement with duplicate frame or signal keys preserves the existing frame and signal lookups.

              +

              +End-to-end pipeline coverage

              +

              dbc_pipeline_test.cpp parses temporary DBC files and checks independent expected metadata against the parser, runtime builder, and tree builder. It exercises standard and extended frames with the same numeric ID and signal name, Intel and signed Motorola decoding, scaling, raw value descriptions, basic multiplexing, PGN metadata, receivers, units, ranges, and frame/signal comments. Tree checks include node types, payloads, parents, rows, names, and child counts.

              +

              Empty and headers-only fixtures produce an empty runtime database and a valid empty tree root. Replacement fixtures change definitions, metadata and decoded values, remove old lookup keys, and then clear both outputs through an empty fixture. Saved decoded results and trees retain their original metadata.

              +

              +Attribute coverage

              +

              Parser slots attributes, invalidAttributes, and attributeWarnings cover all five scopes and types, deferred definitions/defaults/targets, explicit values overriding defaults, repeated assignments, escaped strings, typed range/scope errors, duplicate definitions/defaults, unknown attributes and missing targets. They check source diagnostics and the throwing API, distinct standard/extended targets, frame cycle times and enum labels, unsupported formats and ID conflicts, unchanged J1939 opt-in, and runtime/tree propagation. Existing unsupported-statement checks now use relation forms, which remain unsupported, instead of supported attribute forms.

              +

              Attribute changes were verified with qmake6 ../dbc.pro, make -j4, and make check in build/: all six QtTest suites and the qmake tree target passed. The standalone C++17 tree test also passed. The existing named comma-decimal C locale test skipped because the locale is not installed.

              +

              +Extended validation

              +

              attributeNumbers checks signed 64-bit limits, leading plus signs, decimal HEX values, FLOAT fractions/exponents, and default overrides under a comma-decimal C++ locale. Node/environment defaults remain on definitions without becoming database attributes. invalidAttributeNumbers supplies 39 data rows, each checked in both definition bounds, a default, and an explicit assignment. The throwing and diagnostic APIs must reject malformed signs, trailing text, hexadecimal notation, non-finite values, overflow, and underflow with the correct error line. Additional malformed-attribute cases cover token separators, scope/type names, reversed FLOAT bounds, value types/ranges, and invalid CAN references.

              Generate the optional German locale as described above before setting LOCPATH. LeakSanitizer cannot run under this environment's tracer: detect_leaks=1 completes the core QtTest suites but fails during leak checking with the message that LeakSanitizer does not work under ptrace. Disabling leak checking retains AddressSanitizer and UndefinedBehaviorSanitizer checks; it does not verify leaks.
