From 853ee3341572885ff2cb1d5d251e9280fa2ee463 Mon Sep 17 00:00:00 2001 From: Breadway Date: Fri, 17 Jul 2026 09:15:54 +0800 Subject: [PATCH] Add bread-utils and bread-onnx: shared crates for ecosystem-wide duplication bread-utils extracts genuinely duplicated logic found across breadbox, breadclip, breadmon, breadcrumbs, bos-settings, and breadhelp: - hypr: Hyprland socket1 request/response client (breadbox's get_active_workspace + breadclip's position.rs hyprctl_json were near-identical), socket2 path resolution (breadmon), and a version-tolerant `fullscreen` field parser (Hyprland has shipped both bool and int representations across versions). - singleton: correct flock-based single-instance toggle, replacing the TOCTOU-prone read-pid/check-proc/kill/write-pid pattern duplicated verbatim between breadbox and breadclip (breadclip's own comment says "matches breadbox pattern"). - proc: breadcrumbs' timeout-guarded subprocess runner, promoted verbatim as the one implementation in the ecosystem that already got this right. - atomic + xdg: atomic (temp-then-rename) file writes with an optional .bak-before-overwrite variant, and XDG path helpers that never fall back to a literal "~/..." string (the exact breadclip-core and breadpad-shared bug: PathBuf never expands `~`). - tomlcfg (feature "toml"): the load_doc/save_doc TOML-editing discipline bos-settings and breadhelp both implemented byte-for-byte identically in the same fix pass that introduced it. - gtk_popup (feature "gtk"): layer-shell overlay window setup, visible-row navigation, and click-outside-close, deduplicated from breadbox and breadclip (~150 duplicated lines, per both apps' own "same as breadbox" comments). bread-onnx extracts the embedding pipeline (tokenize -> tensor build -> mean-pool -> L2-normalize) duplicated near-verbatim between breadarr and breadsearch, a shared execution-provider session builder with loud EP- registration logging, and a model download+integrity helper. Defaults AMD iGPU acceleration to ort::ep::MIGraphX (not ROCm) per this machine's own breadsearch-gpu-backends lesson: ROCMExecutionProvider silently no-ops to CPU on distro ROCm onnxruntime builds compiled with --use_migraphx. Both crates build and pass their own test suites standalone. Consumer migrations follow in subsequent commits. --- Cargo.lock | 775 ++++++++++++++++++++++++++++++++++- Cargo.toml | 3 +- bread-onnx/Cargo.toml | 34 ++ bread-onnx/src/download.rs | 112 +++++
