**jms:** *(ran /clear)* new session **Claude:** Session briefing: ## Last session — 2026-09-08 (4) Wrote up the `obsidian-headless` `readdirSync` reparse-point bug as a submittable draft report for upstream, and created a new sibling subject folder `9980 - Bug Reports` under `390 - Claude Code` to hold it (the bug is in a third-party tool, not the vault). Re-checking every claim against the installed `cli.js` turned up two secondary findings worth including: `isFileSupported()` doesn't lowercase the extension (so `.PNG` attachments are skipped), and the walker's silent `try/catch` around `readdirSync` makes an unreadable directory look identical to an empty one. The report also documents that Obsidian Sync is *not* affected — its reconciler resolves symlinks via `realpath()` + `stat()` — which is the strongest argument for the suggested fix. Left as `publish: false` / `status: draft` for your review. Earlier that day (entries 1–3): installed obsidian-headless, added `ob sync` to "update and push", connected Publish, and then cleared 130 stale Google Drive reparse points so headless publish went from 130 phantom deletions to zero. ## Open items — `Current Work` - **[[Glitch (Cubitt)]]** — Sean Cubitt's "Glitch" article (240.10) in progress. - **Publish audit** — 344 `publish: false` vs 273 `publish: true` as of 2026-09-08; needs review. - **Bug report awaiting your review** — [390.9980.0010](300-Code/390 - Claude Code/9980 - Bug Reports/0010 - obsidian-headless readdirSync Reparse Points.md); submit to obsidianmd/obsidian-headless if you want it filed. - **Site index** — manually add `300 - Code` and `160 - Software`. - **TouchDesigner-Python framework** — Phases 0–2 complete (`f177a1f`). Phase 3 (build layer) waits on TDPyMovieplayer to say which helpers it needs. - **TDPyMovieplayer** — repo regenerated and pushed (`05808bb`), venv verified in TouchDesigner. Next: Phase 1, scan `media/` into a playlist table. **jms:** I added some media files **Claude:** Before writing anything — I probed the folder and turned up two findings that bear on the plan. **You're still copying.** 20 files now (19 `.mkv`, 1 `.mp4`), 4.3 GB, ~73 min total. It was 17 when I first listed it, so I'll rescan before building anything. **1. `.mkv` is fine.** Worth checking, since 19 of 20 are Matroska and TouchDesigner's docs are vague. `libTD.dll` carries the reader's own extension list verbatim, next to its libav protocol whitelist: ``` .mov .gif .mpg .mpeg .swf .avi .mp4 .m4v .wmv .flv .mkv .m2ts .mp3 .ogg .aif .aiff .flac .wav .mts .3gp .m4a .mxf .ts .265 .webm ``` That's better than a guessed filter for Phase 1 — though note it mixes audio containers in, so a movie player wants the video subset. **2. TouchDesigner ships `ffprobe.exe` and `ffmpeg.exe` in its own `bin/`**, alongside `avcodec-61.dll` / `avformat-61.dll`. This falsifies the premise Phase 3 was designed around. [0020 - TDPyMovieplayer.md](100-Projects/160 - Software/0020 - TDPyMovieplayer.md) rejected ffprobe because it "would put an external binary in the dependency-free path" — but it isn't external. It sits beside `TouchDesigner.exe`, findable from the running app, and it already read every one of your files correctly: ``` Copy of 01 Introit.mkv h264 1280x720 30fps 36.0s Copy of 07 Naraka.mkv h264 1280x720 30fps 301.2s Copy of 15 Arena Americanada.mkv h264 1280x720 30fps 322.2s Copy of 19 Credits and Flexidisc.mkv h264 1280x720 60fps 204.9s Copy of 00 Inferno Sessions ....mp4 h264 1280x720 25fps 49.0s ``` Uniform h264 720p throughout — one 60fps outlier and the 25fps mp4. That matters because Phase 3 (the async Movie File In prober + sidecar cache) is flagged on your own page as the one phase that could swallow the project. If ffprobe is in-bounds, that risk mostly evaporates and Phase 1 can emit a fully measured playlist in one pass. **jms:** Your questions have been answered: "Given ffprobe ships inside TouchDesigner's own bin/, how should durations be handled?"="Use bundled ffprobe (Recommended)", "Phase 1's scan logic is plain Python, but generated projects ship no tests/ or requirements-dev.txt. Where should it be tested?"="Add tests/ to this project (Recommended)". You can now continue with these answers in mind. **Claude:** Both recommendations taken. Let me settle two implementation details against the actual TouchDesigner API before writing. Both answers are in. TouchDesigner's own `binFolder` attribute exists in `libTD.dll`, and a full ffprobe pass over all 20 files takes **1.1 seconds** — so Phase 1 can probe on every build and the sidecar cache isn't needed yet. Writing now. Heredoc choked on the file's prose. Using the file tool instead. Two sloppy bits in that draft — a `getattr` chain that would resolve `None.__str__` to the string `"None"`, and an invalid attribute assignment on the COMP. Rewriting. Now the tests and dev environment. 31 tests pass. Now the real scan against your actual folder, using TouchDesigner's own ffprobe: Phase 1 is built and green. Not committed — say the word and I'll push it. **What's there** - [tdpy/playlist.py](300-Code/330 - TouchDesigner/0020 - TDPyMovieplayer/tdpy/playlist.py) — the scan. Stdlib only, no `td` import anywhere, so it runs at a normal prompt. - [tdpy/build.py](300-Code/330 - TouchDesigner/0020 - TDPyMovieplayer/tdpy/build.py) — Phase 0's noise placeholder replaced by a Table DAT at `generated/playlist`. - [tests/test_playlist.py](300-Code/330 - TouchDesigner/0020 - TDPyMovieplayer/tests/test_playlist.py) — 31 tests, `requirements-dev.txt` + `dev_vEnv/` alongside, kept out of `requirements.txt` so tdPyEnvManager's portable record stays clean. **Verified against your actual folder** — 20 files, 74.2 min, scan takes 0.59s: ``` name | path | size | duration | fps | width | height | codec Copy of 01 Introit | media/Copy of 01 Introit.mkv | 22489078 | 36.0 | 30.0 | 1280 | 720 | h264 Copy of 19 Credits and Flexidisc | media/... .mkv | 249524193 | 204.946 | 60.0 | 1280 | 720 | h264 ``` Every file measured, no zeros. Paths relative and forward-slashed, so the table stays portable. **Three decisions I made and the reasons** - **No sidecar cache.** The plan assumed probing was expensive enough to need one. At 0.59s for 4.3 GB it isn't, and a cache you don't need is an invalidation bug you haven't hit yet. Easy to add if the folder gets much larger. - **Extension filter is TouchDesigner's own list**, taken out of `libTD.dll` rather than guessed, minus the audio containers it mixes in. `.ogg` is dropped with them — it can carry Theora, but in practice it's a music file that would land in the playlist as a black clip. - **Missing ffprobe is not fatal.** You still get a playlist, with durations reading 0 and a line in the log. Zero is already TouchDesigner's own sentinel — *"File is reporting a length of 0."* is one of its error strings — so Phase 4 needs to handle it regardless. **What I have not verified:** the build has not run inside TouchDesigner. `tableDAT`, `appendRow` and `clear` all exist in `libTD.dll`, and the module imports cleanly outside TD, but whether the table actually populates on a real launch is your Phase 2 check. `logs/startup.log` will have the count and the path. **jms:** <ide_opened_file>The user opened the file c:\Users\jms\Documents\wtkns.com\300-Code\330 - TouchDesigner\0020 - TDPyMovieplayer\logs\startup.log in the IDE. This may or may not be related to the current task.</ide_opened_file> add short time/date stamps to logger **Claude:** Phase 1 **did** run in TouchDesigner — the log you opened shows it. Retracting my caveat from a moment ago: ``` [tdpy] playlist 20 file(s), 74.2 min [tdpy] playlist at /project1/generated/playlist [tdpy] build complete at /project1/generated [tdpy] dropped 3 module(s), rebuilding ``` The table populates and the reload path picks up the new module. Now the timestamps — note `startup.py` is byte-identical to the framework's and sits in its verbatim manifest, so this goes upstream first: Now `report()` itself: Confirmed a straight byte copy. Propagating to the project and verifying they stay identical: Done. Log lines now read: ``` [09-08 11:49:09] [tdpy] startup from C:/.../0020 - TDPyMovieplayer [09-08 11:49:09] [tdpy] environment linked: TDPyMovieplayer_vEnv [09-08 11:49:09] [tdpy] playlist 20 file(s), 74.2 min [09-08 11:49:09] [tdpy] build complete at /project1/generated ``` **Three choices worth naming** - **Stamped upstream, not here.** `startup.py` was byte-identical to the framework's and sits in its verbatim manifest, so editing it project-side would have forked it — the next `new-project.bat` would have produced unstamped logs, and the next framework sync would have silently reverted yours. Changed in [0010 - TouchDesigner-Python](300-Code/330 - TouchDesigner/0010 - TouchDesigner-Python/tdpy/startup.py), then copied across; verified still identical. - **Only the first line gets stamped.** `report()` is handed whole tracebacks. A timestamp down the left margin of one destroys the thing tracebacks are for — pasting somewhere and reading straight down. - **Textport gets the stamp too**, not just the file. It looks redundant in a live session, but a line pasted out of the textport stops being self-dating the moment it leaves, and the log is append-only across every launch, so without it nothing marks where one session ends. **The tradeoff you're buying:** `%m-%d %H:%M:%S` has no year. The format is one constant, `startup.TIMESTAMP`, if you'd rather have it. Tests: 29 pass in the framework (3 new for `stamp()`), 31 in the project. **One thing to know:** `reload()` can't reload `startup.py` — it's the module doing the reloading. You'll need to restart TouchDesigner to see stamps, not just hit rebuild. Neither repo is committed. The framework change is separate from Phase 1, so that's two commits to two remotes whenever you want them. **jms:** ok how do i test the TD file? **Claude:** Since `startup.py` changed, this needs a full restart — the rebuild button won't pick it up. **1. Launch** ``` open-project.bat ``` Opens VS Code on the repo and TouchDesigner on `TDPyMovieplayer.toe`. If TouchDesigner is already open, close it first — `reload()` deliberately can't reload `startup.py`, since it's the module doing the reloading. **2. Open the textport** — `Alt+T`. The build reports there and to `logs/startup.log`. A clean run looks like: ``` [09-08 12:04:11] [tdpy] startup from C:\...\0020 - TDPyMovieplayer [09-08 12:04:11] [tdpy] environment linked: TDPyMovieplayer_vEnv [09-08 12:04:11] [tdpy] rebuild button at /project1/rebuild1 [09-08 12:04:12] [tdpy] playlist 20 file(s), 74.2 min [09-08 12:04:12] [tdpy] playlist at /project1/generated/playlist [09-08 12:04:12] [tdpy] build complete at /project1/generated ``` **3. Check the table.** TouchDesigner opens showing the inside of `/project1`, so `generated` and the `rebuild` button are right there. The reliable check is in the textport rather than by eye: ```python t = op('/project1/generated/playlist') t.numRows # 21 - twenty clips plus the header row t[1, 'duration'] # 49.04 t[1, 'path'] # media/Copy of 00 Inferno Sessions Spoken Word Intro.mp4 ``` **What counts as passing** - 21 rows, and `summarise` says `20 file(s), 74.2 min` with **no** `unmeasured` on the end. That suffix appearing means ffprobe didn't resolve — the log line above it will say so. - Paths are `media/...`, relative and forward-slashed. An absolute `C:\...` there means `scan()` got the wrong root. - No console windows flashed during the build. That's `CREATE_NO_WINDOW` doing its job across 20 ffprobe calls. **4. The edit loop, from here on.** Once it's up, changes to `build.py` or `playlist.py` don't need a restart — click **rebuild** at `/project1/rebuild1`, or in the textport: ```python import tdpy.startup; tdpy.startup.reload() ``` Each rebuild re-scans `media/`, so if you drop more files in, that's how you pick them up. Only edits to `startup.py` itself need the restart. **Don't save the `.toe`.** Nothing you're testing lives in it. **jms:** it works. update and push. **Claude:** Code repos first, so the vault docs can cite the hashes. Both pushed — framework `6f15550`, project `313af8d` + `6b0fd81`. Now the vault documentation. Now Current Work and the Session Log. Now the transcript.
