Added optional `[DBGCACHE]` timing logs for image request/decode and UI refresh paths when `debug_cache` is enabled. -#### Stability +### Stability - Refactored shutdown into `shutdown_qt()` (main thread) and `shutdown_nonqt()` (background-safe), wired from `aboutToQuit` in `main()` with a timeout/stacks fallback to diagnose hangs. - Added cooperative cancellation and `cancel_futures=True` shutdown behavior to both main image and thumbnail prefetchers. - Ensured thumbnail “ready” callbacks run on the Qt thread when available; hardened cancellation/callback ordering to avoid deadlocks and worker-thread Qt warnings. diff --git a/faststack/app.py b/faststack/app.py index 9b729fe..733b086 100644 --- a/faststack/app.py +++ b/faststack/app.py @@ -14,6 +14,7 @@ import re import shutil import uuid +import bisect import functools # Must set before importing PySide6 @@ -50,7 +51,7 @@ from faststack.config import config from faststack.logging_setup import setup_logging from faststack.models import ImageFile, DecodedImage -from faststack.io.indexer import find_images +from faststack.io.indexer import find_images, _parse_developed from faststack.io.sidecar import SidecarManager from faststack.io.watcher import Watcher from faststack.io.helicon import launch_helicon_focus @@ -84,6 +85,20 @@ ) +# AWB thresholds on the -1..+1 normalised slider range. +# NOOP: skip applying correction entirely (≈ 0.64 Lab units — below perceptible). +# LABEL: below this the direction word becomes "neutral" in the status message. +_AWB_NOOP_EPS = 0.005 +_AWB_LABEL_EPS = 0.002 + + +def _awb_direction(value: float, pos_label: str, neg_label: str) -> str: + """Return a human-readable direction label for an AWB shift value.""" + if abs(value) < _AWB_LABEL_EPS: + return "neutral" + return pos_label if value > 0 else neg_label + + def make_hdrop(paths): """ Build a real CF_HDROP (DROPFILES) payload for Windows drag-and-drop. @@ -157,6 +172,7 @@ def __init__( self._shutting_down = False # Flag to gate async callbacks during shutdown self._refresh_scheduled = False # Coalesce guard for deferred disk refresh self._opencv_warning_shown = False # Only show OpenCV warning once per session + self._last_auto_levels_msg: str = "" # Detail message from last auto_levels() call self.image_dir = image_dir self.image_files: List[ImageFile] = [] # Filtered list for display @@ -712,6 +728,77 @@ def _rebuild_path_to_index(self): img.path.resolve(): i for i, img in enumerate(self.image_files) } + def _insert_backup_into_list(self, backup_path: str, current_path: str) -> bool: + """Insert a newly-created backup file into the image list without a full rescan. + + Uses bisect.bisect_right with the same sort key as indexer.py to maintain + order, then list.insert at the found position. + Falls back to refresh_image_list() on any error. + + Returns True if the current_path was found in the updated list. + """ + try: + bp = Path(backup_path) + cp = Path(current_path) + mtime = bp.stat().st_mtime + img = ImageFile(path=bp, raw_pair=None, timestamp=mtime) + + # Sort key matches indexer.py:70 — (mtime, name_cf, is_developed, name_cf) + # Backup files don't match the -developed suffix, so position 2 = 0 + key = (mtime, bp.name.casefold(), 0, bp.name.casefold()) + + # Build parallel key list for bisect — uses _parse_developed from + # indexer.py so the is_developed bit stays in sync with the canonical rule. + # f.timestamp is st_mtime, set in indexer.py:68 (ImageFile(timestamp=stat.st_mtime)). + # Rebuilding keys is O(n) but still far cheaper than a full directory scan. + keys = [ + ( + f.timestamp, + f.path.name.casefold(), + int(_parse_developed(f.path)[0]), + f.path.name.casefold(), + ) + for f in self._all_images + ] + idx = bisect.bisect_right(keys, key) + self._all_images.insert(idx, img) + + # Re-apply filter and rebuild index + self._apply_filter_to_cached_list() + + # Re-derive current_index from the updated path-to-index map + resolved = cp.resolve() + new_idx = self._path_to_index.get(resolved) + if new_idx is not None: + self.current_index = new_idx + return True + + # Name-based fallback (handles drive letter / symlink mismatches) + target_name = cp.name + for i, img_file in enumerate(self.image_files): + if img_file.path.name == target_name: + self.current_index = i + return True + + log.warning( + "_insert_backup_into_list: could not find %s after insertion", current_path + ) + return False + + except Exception: + log.warning( + "_insert_backup_into_list: falling back to refresh_image_list", + exc_info=True, + ) + self.refresh_image_list() + # Attempt to find current_path in refreshed list + target_name = Path(current_path).name + for i, img_file in enumerate(self.image_files): + if img_file.path.name == target_name: + self.current_index = i + return True + return False + def get_decoded_image(self, index: int) -> Optional[DecodedImage]: """Retrieves a decoded image, blocking until ready to ensure correct display. @@ -5007,24 +5094,22 @@ def auto_levels(self): if self.ui_state.isHistogramVisible: self.update_histogram() -

Write better docum - Improve auto-levels/AWB UX: detailed status messages and per-stage timing logs (compute/save/list/total). - Track last auto-levels detail string for “saved” message reuse; minor import/indexer integration tweaks. - Centralize canonical image sort key in indexer; store developed adjacency name on ImageFile. +- Sync filename filter to the thumbnail grid model (apply/clear) and cancel stale thumbnail prefetch jobs so filtered thumbnails load quickly. +- Add debug timing logs for auto-levels and auto white balance (subsample/mask/Lab compute) to pinpoint slow stages. +- Add debug-only timing breakdowns for image load, auto-levels percentile analysis, and save pipeline in `ImageEditor`. +- Refactor `ThumbnailModel` filtering into `set_filter()` with an active filter state; assert refresh runs on the GUI thread to catch threading mistakes.` ## 1.5.6 (2026-02-08) From 346074ee133c20c883d64b8c8924ed7861c835a3 Mon Sep 17 00:00:00 2001 From: AlanRockefeller Date: Mon, 9 Feb 2026 23:34:13 -0500 Subject: [PATCH 05/16] =?UTF-8?q?Export=20performance:=20Skip=20the=20expe?= =?UTF-8?q?nsive=20sRGB=E2=86=92Linear=E2=86=92sRGB=20round-trip=20when=20?= =?UTF-8?q?no=20linear-space=20edits=20are=20active=20(WB/exposure/highlig?= =?UTF-8?q?hts/shadows/clarity/texture/sharpness),=20and=20clamp=20export?= =?UTF-8?q?=20output=20to=20[0,1]=20on=20that=20path.?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Save performance: Avoid float_image.copy() during export when the edit set guarantees the pipeline won’t mutate the input buffer. Load performance: Apply EXIF orientation on the 8-bit Pillow path before float conversion (rotate uint8), and only rotate the float buffer on the 16-bit OpenCV path. Logging/robustness: Switch warnings/errors to lazy log formatting and improve load/save diagnostics. --- faststack/imaging/editor.py | 711 ++++++++++++++----------- faststack/tests/test_editor_no_copy.py | 182 +++++++ faststack/tests/test_skip_linear.py | 124 +++++ 3 files changed, 715 insertions(+), 302 deletions(-) create mode 100644 faststack/tests/test_editor_no_copy.py create mode 100644 faststack/tests/test_skip_linear.py diff --git a/faststack/imaging/editor.py b/faststack/imaging/editor.py index 1a49c2a..5b6bad7 100644 --- a/faststack/imaging/editor.py +++ b/faststack/imaging/editor.py @@ -96,7 +96,7 @@ def create_backup_file(original_path: Path) -> Optional[Path]: shutil.copy2(original_path, backup_path) return backup_path except OSError as e: - log.exception(f"Failed to create backup: {e}") + log.exception("Failed to create backup: %s", e) return None @@ -172,7 +172,7 @@ def _gaussian_blur_float(arr: np.ndarray, radius: float) -> np.ndarray: return np.stack(blurred_channels, axis=-1) except Exception as e: - log.warning(f"Fallback blur failed: {e}") + log.warning("Fallback blur failed: %s", e) return arr # Sigma calculation matching Pillow's radius-to-sigma @@ -407,6 +407,59 @@ def _initial_edits(self) -> Dict[str, Any]: "straighten_angle": 0.0, } + @staticmethod + def _edits_skip_linear(edits: Dict[str, Any]) -> bool: + """True when no linear-space edits are active (WB, exposure, highlights, + shadows, clarity, texture, sharpness).
