Reclaim: a Quick Wins scan for regenerable trees, with eight views (#58) - #59
dzulfikar08 wants to merge 4 commits into
Conversation
A reclaim request walks a root for regenerable directories (node_modules, target, dist, build, .venv, __pycache__ and friends), sizes each one with the dirsize walker, seeds the dirsize cache with what it measured and answers a listing ranked heaviest first. A result is a listing like any other, so window, thumb, trash and undo work unchanged; rows the walk never sized are sized on demand. On a reclaim listing a directory row's s is the measured bytes, which is what the views read. The GUI: R scans the directory the pane stands in, b opens and cycles the eight readings — treemap, folders, sunburst, flame, bubbles, mind map, top sizes, age map — drawn by ui/js/ReclaimTree.js's layouts and ui/js/ ReclaimPaint.js's one drawer, over the same tree built from the rows. The strip's Quick Wins stages every listed tree for the trash through the existing trash request, so undo covers it. The walk is the search walk's shape: bounded slices, one match sized per tick, a cancel that is never behind more than one tree, streaming progress reclaiming lines and a terminal reclaimed line. Matches are never descended into, symlinks are never matched, other filesystems are never entered. docs/protocol.md documents the wire; tests/protocol.sh drives the real backend through eleven reclaim checks and Reclaim.rs carries nine sandbox unit tests.
📝 WalkthroughWalkthroughThe change adds a reclaim scan for regenerable directories. It streams progress, supports cancellation, ranks results, seeds directory-size data, and adds UI controls plus eight reclaim result visualizations. ChangesReclaim feature

In `@ui/PaneWire.qml`:
- Around line 159-160: Update PaneWire.onFailed for the active reclaim

Escape can proceed to close normally.
In `@ui/ReclaimMap.qml`:

- Around line 136-144: Update the qwTap onSingleTapped handler to resolve the
selected paths, terminate the active reclaim operation, and invalidate its
listing state before invoking Ops.trash(root.pane). Preserve the existing
selectAll behavior and ensure trash receives the resolved selection only after
the reclaim walk has stopped.

The chrome bar gains a broom button beside the views it draws: one press scans where the pane stands and opens the views over it, a press on an open overlay toggles back to the listing, and the button lights while the views stand. It is the pointer's half of the R key. Quick Wins no longer deletes anything. It selects every tree the scan found and steps the overlay aside, so the listing comes back with the trees highlighted and the seeing comes before the dd; z and esc back out of the selection, undo stays behind the trash that follows.

- ListPaths ends a running reclaim (and its measured-bytes flag) before the picker's listing replaces it, exactly as list and search do. - The device check now refuses a foreign-filesystem entry before the target match, so a mount named node_modules is neither listed nor sized across the boundary; the cross-filesystem test grows the target-named child. - Top Sizes sorts its bars descending: tree discovery order is readdir order, not the rank the listing answers in. - A backend failure clears a running scan's flag, so esc closes instead of cancelling a walk nothing is walking. - The views overlay stores its painted shapes where click hit-testing reads them, so a click lands the cursor on the row it drew. - Quick Wins staging waits for the terminal line: a mid-walk rank would reshuffle the selection it hands back. - protocol.md states a cancelled walk's bytes total covers the trees sized before the cancel.
The chrome edit that added the reclaim button replaced the line the back arrow's handler lived on, so a click on the arrow stopped going back. onBackRequested is back on the pane, next to its up sibling.

Reject entries when device metadata is unavailable.
If entry.metadata() fails, unwrap_or(0) produces an apparently acceptable device. Line 156 then permits the entry, so the walker can descend into or match a filesystem that it did not verify. Treat metadata failure as continue, and represent an unavailable root device separately from a real device value.

Closes #58 — a DiskBuddy-style Quick Wins scan, built on the patterns the tree already ships.
What it does
reclaimwalks a root for regenerable directories —node_modules,target,dist,build,.next,.venv,__pycache__and nineteen more exact base names — sizes each match with thedirsizewalker, and answers a listing ranked heaviest first. Per this repo's own rule that a result is a listing like any other,window,thumb,trashand every per-row facility work unchanged: the operator selects rows andddtrashes them, withz(undo) behind it. No new destructive primitive exists anywhere in this patch.The GUI: R scans the directory the pane stands in; b opens the views overlay and cycles the eight readings — treemap, folders, sunburst, flame, bubbles, mind map, top sizes, age map — all renders of one tree built from the rows. The overlay's Quick Wins button stages every listed tree for the trash in one press; undo covers it.
