- snapshot: depth limit (stack overflow in exporters), decompressed-size
limit (gzip bombs), per-node size cap and saturating aggregation
- export: sanitise exclusion patterns from snapshot metadata
- tui: drop duplicate/trash/filter results that belong to a replaced
tree; cancel duplicate search on rescan
- trash: refuse symlinked or foreign shared-filesystem trash dirs; never
overwrite an existing trashed item
- scan: no symlink following without inode identity; correct unscanned
count and keep real read errors after cancellation
Dark shades map to black and greys to the grey/white entries while
saturated category colours keep their hue, instead of the stock
conversion's bright yellow/cyan shadows.
Decompression and checksumming overlap with parsing via a pipe, and a
concrete-typed varint reader removes per-byte interface calls
(0.39s -> 0.29s for 458K nodes).
--compare opens the TUI with growth/shrink colouring unless a report is
requested. treegen builds deterministic synthetic trees (Unicode,
hostile names, sparse files). MAPSIZE_DEBUG_PANIC verifies terminal
restoration on UI and scanner panics.
Edge-snapped integer layout that partitions its bounds exactly,
level-of-detail selection, and a deterministic geometric neighbour
search for arrow-key navigation. Fuzz-tested.
Lexer, recursive-descent parser (AND/OR/NOT, parentheses, implicit AND,
IN lists, size/age/date units) and an evaluator that computes filtered
subtree sizes in two linear passes without double counting.
Single-writer controller with a select loop that offers jobs and accepts
results simultaneously, so bounded channels cannot deadlock. statx/fstatat
relative to the directory fd on Linux/macOS, portable fallback elsewhere.
Hard links counted once, symlink loops detected, virtual filesystems
skipped, errors classified and surfaced.
