Payload policy uses `dlc` as a byte count, including for CAN FD; it is not the

## Unreleased

### 2026-10-13
|
||||
|
||||
#### Added
|
||||
|
||||
- `FrameDecodeStatus` distinguishes unknown frames, insufficient payloads,
|
||||
signal errors, and successful decoding; frame `valid` still means matched.
|
||||
- `SignalDecodeStatus::PhysicalConversionFailed` reports NaN/Inf results,
|
||||
retaining exact raw values and the non-finite physical result.
|
||||
- Regression tests for payload-length policy, partial results, invalid runtime
|
||||
metadata, physical overflow/non-finite parameters, and raw branch selection
|
||||
when selector physical conversion fails.
|
||||
|
||||
#### Changed
|
||||
|
||||
- Short payloads decode available signals without padding; longer payloads
|
||||
ignore bytes beyond the declared DLC. Short frame status takes precedence
|
||||
over signal errors, with per-signal causes retained in definition order.
|
||||
- Runtime signal validation checks enum values and bit layouts against declared
|
||||
DLC using overflow-safe coordinates. Extra bytes cannot rescue invalid layouts.
|
||||
- Documented frame/signal status meanings, value availability, and payload policy.

<p>Short-payload status takes precedence over signal errors; inspect each signal's status for the individual cause. <code>valid</code> retains its existing meaning of a matched definition and does not imply <code>status == FrameDecodeStatus::Valid</code>.</p>
|
||||
<p>Payload policy uses <code>dlc</code> 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 <code>dlc</code> are ignored. Signal bit layouts must fit the declared <code>dlc</code>, 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.</p>
|
||||
<p>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 <code>PhysicalConversionFailed</code>. The exact raw value and non-finite <code>physicalValue</code> remain available, while signal <code>valid</code> is false. Non-finite factor/offset in manually constructed definitions follow this same conversion-result check. Physical conversion failure of a selector does not prevent raw branch selection.</p>

Definition ownership and reload</h2>

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.</p>
|
||||
<p>Reload by assigning a newly built database. Stored results continue to describe the old DBC, including its units, scaling, comments, and <code>VAL_</code> 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.</p>
|
||||
<p><code>GetFrames()</code> is a borrowed view. References, iterators, and raw pointers obtained from it or from a handle's <code>.get()</code> do not retain ownership. Keep an owning handle or an unchanged database copy while using them. Do not retain mutable aliases into a vector moved into the database constructor. The raw string pointer from <code>GetValueDescription()</code> follows the same rule: keep the signal definition handle alive while using the string.</p>

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.</p>

Both are value types with equality and hashers (<code><a class="el" href="structFrameKeyHasher.html" title="Hasher for frame key.">FrameKeyHasher</a></code>, <code><a class="el" href="structSignalKeyHasher.html">SignalKeyHasher</a></code>) for application maps and saved selections. Construct the same keys from parsed metadata when needed; do not use addresses or vector positions as identifiers.</p>
|
||||
<p>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 <code>valid</code>/the definition handle to distinguish a matched result; default keys alone do not indicate successful decoding.</p>

<p>Coverage includes Motorola bit numbering within and across bytes, unaligned signals, signed values, scaling, 64-bit extraction, signed/unsigned boundary values (including <code>INT64_MIN</code>, <code>INT64_MAX</code>, and <code>UINT64_MAX</code>), numeric output, invalid lengths, insufficient payloads, and Intel regression cases.

<p>Coverage includes Motorola bit numbering within and across bytes, unaligned signals, signed values, scaling, 64-bit extraction, signed/unsigned boundary values (including <code>INT64_MIN</code>, <code>INT64_MAX</code>, and <code>UINT64_MAX</code>), 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, and preservation of successful signals. Physical conversion checks cover NaN/Inf parameters, multiplication/addition overflow, finite limits, signed/unsigned raw retention, and raw selector activation after physical conversion failure.</p>
|
||||
<h1><a class="anchor" id="autotoc_md139"></a>
|
||||
Parser coverage</h1>
|
||||
<p>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 <code>FileReadError</code> path.</p>
|
||||
<p>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 <code>VAL_</code> 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.</p>
|
||||
<p>Dispatch tests also verify exact keyword matching, handler construction and reuse, unknown statements, and independent parsing sessions, including recovery after errors.</p>

Tree and optional model tests</h1>
|
||||
<p><code><a class="el" href="tree__node__test_8cpp_source.html">tree_node_test.cpp</a></code> is a standalone C++17 executable without Qt; see the root README for its compiler command. It checks parents, sibling positions, null children, bounds, and unique_ptr transfer.</p>
|
||||
<p>Enable <code>CONFIG+=dbc_qt</code> in the root qmake invocation to build <code>dbc_qt</code> and <code>dbc_model_tests</code> alongside existing tests. Qt 6.8.2 is required. <code>make check</code> 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 <code>QT_QPA_PLATFORM=offscreen</code> when the variable is unset or empty, so no display server is needed. An explicit platform setting is preserved.</p>
|
||||
<p>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_.</p>

Additional regression coverage</h1>
|
||||
<p><code><a class="el" href="dbc__coverage__test_8cpp_source.html">dbc_coverage_test.cpp</a></code> runs as part of <code>dbc_tests</code>. It covers signed boundaries below 64 bits, deterministic extraction comparisons for both byte orders across lengths 1–64, frame lookup failures, exact decode statuses, malformed runtime multiplexing, PGN boundaries, comment handling, file formatting, metadata copying and source lifetime, physical conversion, and <a class="el" href="classTypeFactory.html" title="Registry-based factory for creating objects by runtime identifier.">TypeFactory</a> registration/creation. Direct resolver tests construct ambiguous databases through the public metadata API, verify source locations, and check that ambiguous targets receive no values.</p>
|
||||
<p>All QtTest targets use Qt 6.8.2 and <code>QVERIFY_THROWS_EXCEPTION</code>. Exception tests explicitly discard <code>nodiscard</code> results when only the exception is being checked. The standalone tree test requires only a C++17 compiler.</p>

<h1><a class="anchor" id="autotoc_md139"></a>
|

<h1><a class="anchor" id="autotoc_md142"></a>
|
||||
Definition lifetime and reload coverage</h1>
|
||||
<p><code><a class="el" href="dbc__lifetime__test_8cpp_source.html">dbc_lifetime_test.cpp</a></code> 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.</p>
|
||||
<p>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. </p>
