fix(node): index, serve and write files past Windows' MAX_PATH

2026-10-14T09:17:38Z

With the system's default setting (LongPathsEnabled off) every call given a plain path of 260 characters or more refuses it, so a deep library was partly invisible: the walk could not list such a directory and its files never reached the members. The node now hands each call that touches a group's disk the extended form (paths.long_path), and keeps the plain path in the index, the hash cache and the log. A directory is listed under its long form and its entries named from the plain one (indexer.walk_files, wire._walk_dirs). Covered: the walk, stats and hashing, reconcile and the watcher, the folder list members see, serving over WebRTC and QUIC, deletion, uploads and their recovery, folder creation and removal, audio tags and the cover beside a track, photos, and a show's episode numbering. ffmpeg extends a long path itself and keeps the plain one. long_path now normalises before prefixing (the extended form skips the system's normalisation) and starts at 248 characters, where creating a directory is already refused. test_long_paths.py runs with the setting off: 15 of its 17 tests fail without the change. Checked by hand in the installed app with files at 312 to 380 characters. Co-Authored-By: Claude Opus 5.5

feat(node): log what a transfer moved when it ends

One INFO line per lease: bytes, duration, rate, and the SCTP association's window, round trip, losses and T3 expirations. Co-Authored-By: Claude Opus 5.5

feat(node): refuse an upload on a full disk with a stated reason

2026-10-09T16:23:56Z

Nothing on the upload path knew about ENOSPC: a write that found no room raised out of the handler, the catch-all answered "Request failed", and the .part stayed behind holding the space that had run out. The node now refuses with `disk_full` at chunk 0 when the announced size would leave less than 1 GiB free, and at any write that fails with ENOSPC/EDQUOT, dropping the partial. The client carries the code on the error and the transfers panel says "The node's disk is full" in every catalogue. Co-Authored-By: Claude Opus 5.5

fix: downloads are marked and keep their extension; Explorer files are refused

2026-10-01T09:47:39Z

The desktop app writes the Mark-of-the-Web on each file it saves on Windows, as a browser does. Bidirectional controls are reserved characters in a saved name (portable-name.js and paths.sanitize_for_download, and again in the main process), so a name cannot display one extension and carry another. The node refuses uploads of files Windows Explorer acts on by itself: desktop.ini, .lnk, .url, .scf, .library-ms, .searchConnector-ms (F-19). Co-Authored-By: Claude Opus 5.5

fix(node): an upload never replaces a file, nor shares a part with another

2026-10-01T07:57:11Z

A name an upload in flight will take is reserved; each upload writes its own `name..part`; the finished file is published by a hard link, which refuses an existing target, and takes the next free name if one appeared meanwhile — the last ack names it. Two members sending one name at once wrote one part and published it twice; a file copied in during an upload was replaced (F-09). Co-Authored-By: Claude Opus 5.5

refactor(node): move uploads out of webrtc_server

2026-09-24T14:45:38Z

UploadMixin in transport/webrtc/upload_handlers.py, with the upload cap; _upload_chunk moved unchanged, _append_chunk joins webrtc/disk.py. Co-Authored-By: Claude Opus 5.5
