2026-09-15Normalized the AI disclosure comment to one fixed line per file (#740)Frédéric Desbiens
The per-edit disclosure named the product and model, so every agent and every model version appended another line. 74 files carried two to four of them, and the same five products had accumulated 13 spellings -- Copilot against GitHub Copilot, Claude Sonnet 4.6 against claude-sonnet-4.6, four spellings of Codex. Twenty assembly lines carried a doubled comment marker, `; //` or `@ //`. Every file now carries exactly one line, fixed text naming no product: Portions of this file were generated with AI assistance. It is written with the comment character that file already uses, so the `;` and `@` assembly files keep theirs and the doubled markers are gone. Precise attribution stays on the commit, where the Assisted-by trailer is per-change, dated and attached to the diff it describes. A header line cannot hold that record honestly, because the code it names gets rewritten and the line stays. A file-level flag answers whether; the history answers who. Comment-only. 455 files, 455 insertions and 574 deletions: every removed line was a disclosure line, every added line is the fixed text, and no file is left with zero or with more than one. `scripts/check_ports.sh` passes, including the reproducibility check that would catch a ports_arch master and its generated copies drifting apart. Recompiled against dev, every file that builds without a vendor toolchain gives a byte-identical object: 19 of 19 C files under common, 100 of 100 GNU assembly files, and all 16 assemblable files whose comment marker changed. The 10 remaining marker changes are ac5 and IAR sources where `;` already started the comment and only the redundant `//` was removed. Assisted-by: Claude Code (Opus 5) <[email protected]>
2026-09-15Guarded _tx_thread_stack_analyze against inverted stack pointers (#727)Frédéric Desbiens
Fixes #460 `TX_ULONG_POINTER_DIF` casts the pointer difference to `ULONG`, so when `tx_thread_stack_highest_ptr` sits below `tx_thread_stack_start` the midpoint wraps to a huge value, the probe lands outside the stack, and the search never converges: the caller hangs or faults. `_tx_thread_stack_analyze` now requires the highest pointer to be strictly above the start of the stack, and bounds the final scan by it. #464 covered the `TX_THREAD_STACK_CHECK` path; this covers direct callers too, as @billlamiework suggested on the issue. Inconsistent pointers still mean a real overflow or a corrupted control block, which remains the application's problem. What changes is that ThreadX reports it through the stack error handler instead of hanging. New cases for an inverted and an equal pointer pair crash the suite without the fix and pass with it.

2026-09-10Made the stack analyze binary search require several consecutive fill words, ↵Frédéric Desbiens
so unwritten holes in a used stack no longer cause the highest stack pointer to be under-reported (#720) The binary search in _tx_thread_stack_analyze() accepted a probe location as unused as soon as a single word still held TX_STACK_FILL. A word inside an otherwise used region that simply was never written - the padding of a partially initialized local array, for example - therefore made the search move away from the real boundary and report far less stack usage than the thread had actually consumed, which in turn kept the stack guard from firing. The probe now walks down from the candidate location and requires TX_THREAD_STACK_ANALYZE_FILL_WORDS consecutive fill words before it treats the location as unused, stopping early at the lowest location already known to hold the fill pattern. The new macro defaults to eight words and can be overridden in tx_port.h; setting it to one restores the previous behavior. Holes shorter than the configured run no longer mislead the search, and the result is unchanged for stacks that contain no such holes. Assisted-by: Copilot (Opus 5) <[email protected]>
