perf(images): share and warm the Images listing (#348, PR 1) (#349)
* perf(images): share and warm one listing per output root (#348) The Images page, its sidebar counts, the subfolder list and the legacy gallery each rebuilt the output listing when the 30 s cache expired, all at once, and the subfolder list computed relative paths on the event loop. Thumbnail writes also threw the listing away. Keep one RootListing per output root (py/api/gallery_listing.py): - one walk per root at a time; concurrent readers wait for it (shielded) - a listing older than 30 s is served at once and refreshed in the background - the walk, the comparison with the previous listing and both folder sets run in the executor; an unchanged walk keeps the same list object - os.scandir probe: a missing root fails the walk and keeps the previous listing (one warning per failure streak) - Rescan waits for a walk started after the click and is a 500 when it fails, even with a previous listing - deletes keep the blocking invalidation; a generation counter that survives drops discards walks that raced it - thumbnail jobs, conversion and the legacy generate/clear routes no longer drop the listing - warm-up on the host's on_startup, cancelled on on_cleanup Adds tools/vendor/perf/images_load_probe.mjs (maintainer tool, not CI) and the TESTING.md section "Images listing cache (#348)". * fix(images): drop listings on the loop when invalidated from a worker thread (#348) A settings save (gallery roots change) and the browser-test seeds call invalidate_gallery_cache() from the executor. Listing records are only touched on the event loop, so an off-loop call now hands the drop to the loop and waits for it, keeping the call synchronous for its callers. The shared-Rescan test waits for the later Rescans to take their walk number instead of sleeping. * test(images): bound the shared-listing test waits (#348) A macOS py3.12 run stopped inside the shared-listing tests and sat until the 6 h job limit with no traceback. It does not reproduce locally (about 300 runs on 3.12 and 3.14, pinned to one core). Requests and background settles in TestSharedListing now give up after 30 s, so a recurrence fails with the stuck await instead of hanging the run. * test(images): let the settle loops yield so a finished walk leaves the set (#348) On CI (ubuntu and macOS py3.12) the runner's watchdog dumped test_a_root_that_recovers_warns_again_on_its_next_failure spinning in _settle: asyncio.gather over tasks that are already done returns without yielding, so the set's discard callback, queued when the walk finished, never ran and the loop never ended (wait_for could not fire either). Delaying discard by one loop turn reproduces it locally; both settle loops now yield one turn after each gather. * test(browser): poll the import review's rows instead of reading them once gridOf reads the dialog's rows once; right after the click the review may not have rendered them yet (firefox CI: received undefined). * perf(images): walk the output with scandir entries and build folders from strings (#348) The live test showed a read during a background refresh taking 2.2 s instead of 0.07 s: the walk held the GIL for about 2 s in the server. py-spy split that walk into two halves: Path.relative_to per file in folder_sets, and Path.stat + Path.is_symlink + Path joins per file in the scan. - _walk_media visits folders in os.walk's order with os.scandir entries: the file type comes from the listing (no lstat per file) and the mtime from entry.stat (one call, none on Windows). _iter_media_files is now a thin wrapper, so its other caller is unchanged. - folder_sets slices the path strings (in the path flavour's separator) instead of calling relative_to, falling back to it for a path that does not start with the root string. On the maintainer's 19,935-file output folder: scan 0.386 s -> 0.112 s, folder sets 0.452 s -> 0.007 s, both results identical to the previous code. A reference copy of the os.walk version checks order, filters, the depth cap, symlinks and the file cap. * perf(images): build the workspace caches behind the warm-up and changed walks (#348) The live test after the faster walk still took 2.9-5.2 s for the first Images open after a restart. py-spy showed the walk was now small; the time went to the workspace's own caches, cold after a restart and built by three parallel first requests at once: the favorites listing (Path.relative_to per file), the per-file values and newest order, and the prompt-link read. - Once the host's startup warm-up has run, a stored walk that changed a listing schedules one executor job that builds what a first page reads, through the request path itself (_select_workspace_page with the default filters, then _workspace_favorite_paths). A walk stored during a build asks for one more build; an unchanged walk (same list kept) builds nothing; a failed build only warns; on_cleanup stops it. Servers that never ran the warm-up (the test servers) start no build. - _favorite_listing slices the path strings as _listed does, falling back to relative_to for a path outside the root string. * perf(images): start a stale listing's refresh walk a second after the read (#348) After the faster walk, a read that found the listing stale still took 0.5-1.0 s against 0.07 s: it was served from the old listing but ran beside the refresh walk it had just started, sharing the GIL. The refresh now starts REFRESH_DELAY (1 s) after that read through a per-root rewalk_handle, so the page's own requests finish first. One pending refresh per root and none while a walk runs; any walk start (a cold read, Rescan, the warm-up) cancels a pending one; on_cleanup cancels them before its first await. * test(browser): accept KB or MB for the picked safety backup's size The restore preview showed '2.5 MB' for the test server's database copy in a CI coverage shard: its size depends on what earlier tests on that server wrote, and the formatter switches to MB at 1 MiB. * fix(images): keep the 3.10-3.13 suffix rule in the scandir walk and harden the warm-up (#348) Review of the walk speedup: - os.path.splitext drops names like ..png that Path.suffix listed on Python 3.10-3.13 (3.14 changed Path.suffix, which hid it from the parity test on a 3.14 venv). _name_suffix spells out the 3.10-3.13 rule; the test now asserts ..png and ...webp are listed and g. is not. - _warm_workspace reads the roots inside its try, so a failing _get_all_output_dirs warns instead of leaving an unretrieved task error. - The folder_sets fallback test now takes the fallback (a Windows case mismatch); the coalescing test pins the walk count. |

feat(system): Backup & export (System S9) (#339)
* feat(system): back up, restore and export natively System > Backup & export replaces its hand-off with the concept's section on the S8 backend: Back up downloads the verified copy and the status line shows only what GET /backup/status reports (D103); Review restore stages a chosen file and shows the server's review in the shared review dialog, Cancel discards the stage and Restore runs the Database restore job, after which the open views reload (D105); Export JSON plus the components and saved-pairs exports (D103); Import / inspect opens the shared Import & inspect dialog; the safety-backup policy saves through the Save row and scheduled backups offer Manual only (D104). Overview's Backup status row reads the same status. Refs #326 * test(system): compare Backup & export with the concept system-backups-concept.spec compares the section, the Restore preview and the Import & inspect dialog with the concept in both themes at 1600 and 390 wide, mapping only D103, D104, D105 (and D15/D55 for the shared Import dialog), and proves a renamed label, a removed row, a lost danger mark and swapped tokens are noticed. A review's grid values now wrap anywhere (D105), so a long backup file name keeps the concept's two equal columns at phone width. Refs #326 * docs(testing): Backup & export contract (D103-D105) Refs #326 * test(coverage): raise the frontend floors S9 measured system-backups.mjs gets its measured floor in place of the provisional one; admin.js, activity-scan.mjs and maintenance-review.mjs branches go up. Refs #326 * fix(system): keep a refused or handed-back restore review usable A Restore refused as busy now opens the same review again with Discard / Restore, and a restore job whose leases did not drain hands its review back (scope.review_kept) to the page that started it, which reopens it; every other path that abandons a token after Restore sends its DELETE, so held reviews can no longer lock restore out. The kept-review line says where the review is, and a full review store says what to do (I1). applyPlan resolves with its outcome and its job tracking now has failing-before proof (N5). Also: the safety-backup toggle says what the policy does (D104, M2); the restore picker has no type filter so safety backups can be chosen (M3); "Export all prompts JSON" names what /export holds (N1); small snapshots show KB (N3); the duplicated holding and save helpers are shared (N4); a dismissal test covers Cancel, x, Escape, a replacing dialog and leaving (M1).
