Add RecordZStackController to record_zstack_controller.py: builds params via setters, pre-warms a JobRunner subprocess (mirrors MultiPointController), resolves a timestamped experiment dir via create_experiment_dir, constructs RecordZStackWorker, and spawns it on a daemon thread. Exposes request_abort(), join(), close(), and per-param setters for the widget. - Fix ZarrWriter._get_loop(): after calling get_event_loop() check that the returned loop is not already closed; if it is, fall through to new_event_loop() so recordings on daemon threads across multiple time-points don't raise 'Event loop is closed'. - Add test_record_zstack_controller_smoke: controller-driven test covering Nt=2 with dt_s=0.1, both recording and z-stack phases, shape assertions.

Compact RecordZStackMultiPointWidget to match WellplateMultiPoint (715px -> 552px): single-column layout; recording channel as a single-row table aligned with the z-stack table (both 530px); one-decimal z-range fields; 'Laser AF' checkbox merged onto the Nt/dt row; left-aligned labels with the Experiment ID field stretched to fill the row. Fix channel-name and fps-suffix truncation in the channel tables. Add FOV-grid wiring test coverage (50 widget tests passing).

(1) _update_scan_regions() called set_well_coordinates() without clearing first; set_well_coordinates only adds wells not already present, so changing region size/overlap/shape was silently ignored for already-selected wells (and stale geometry from the shared scanCoordinates persisted). Clear regions first, mirroring WellplateMultiPointWidget.update_coordinates; adds a call-order regression test (the MagicMock-based tests could not catch this). (2) entry_step setDecimals(1)->(2) so sub-0.1um z-steps are enterable again, widening the step spinbox to 98px so '1.00 um' does not clip; z-min/z-max stay 1-decimal.

charset=UTF-8 Content-Transfer-Encoding: 8bit Fixes the critical/high findings from the streaming/channel-control code review (worktrees/docs/code-review-record-zstack-streaming-2026-07-03.md): - Size the recording dataset from one real processed frame instead of camera.get_resolution(): real cameras crop/rotate frames, so every write failed shape-check and the recording was silently blank. Probe runs in run() after live view stops. - Drain thread counts write_frame failures and seals the store as incomplete (abort) instead of stamping acquisition_complete=True over blank fill; the worker fails fast (aborts the acquisition) on write errors instead of recording blank data at every remaining FOV. - finalize() no longer deadlocks pushing the sentinel into a full queue while the drain thread is wedged in a stalled write (bounded put with fallback to the abort path). - StreamingCapture.run() polls abort_fn while waiting, so Stop works when the camera delivers no frames, and the aborted capture is sealed aborted instead of complete. - run() captures and restores the pre-acquisition trigger mode and channel configuration (record-only runs left the camera stuck in SOFTWARE_TRIGGER; z-stack runs left the last z-stack channel applied with the GUI showing the old one). - zstack()'s trigger-mode fallback keeps liveController.trigger_mode in sync with the camera so acquire_camera_image still gates illumination (a stale mode captured the whole stack dark). - RecordingRouter anchors emission slots to the first frame with a quarter-period tolerance: at-rate delivery jitter no longer rejects alternate frames (halving the capture rate); faster-than-target cameras still downsample correctly. - record() sizes T, pacing, and time_increment_s from the achievable fps returned by set_frame_rate() instead of stalling to timeout and leaving blank trailing planes when the camera clamps the rate. TDD: each fix has a test that failed before it (10 new tests).

TDD: 8 new tests, each watched failing first (except the two gui_hcs wiring changes, covered by the CI gui test file and runtime driver).

Any drop or write error now seals incomplete. - finalize() exposes finalize_wedged; the worker's fail-fast treats a wedged drain as failure (write_error_count reads 0 when finalize returns before the errors happen, so the check alone was bypassable — a stalled disk would have burned the timeout at all remaining FOVs). - finalize()'s sentinel put and join share one timeout budget (a late sentinel followed by a full-length join blocked callers ~2x). - Timepoint pacing uses time.monotonic() (NTP steps skewed wall-clock pacing) and skips slots that already passed, mirroring MultiPointWorker's grid-preserving skip; dt=0 remains continuous. - refresh_channel_list fetches before clearing: a transient get_channels failure (or empty set) no longer wipes the user's configured z-stack rows and combos. - Profile changes now also refresh the tab's channel combos (was objective-only; profile switches replace the channel set too). - _probe_frame_shape rejects color (Y,X,3) frames with a clear error instead of building a dataset every write fails against. - zstack() no longer restores the trigger mode per FOV — run() restores once at the end, removing 2 camera mode switches + 2 MCU commands per FOV. - Hot-path drop warnings are rate-limited (first + every 100th) — per-frame logging at fps rate on the camera delivery thread. Deferred (documented in the review doc): NTP-step handling in RecordingRouter's absolute-slot anchor, a GUI-visible error dialog for fail-fast aborts, folding the achievable-fps probe into ContinuousFrameSource, and app-exit-vs-running-worker hardware races.

slots past T stop the capture instead of writing out of bounds. - A wedged finalize() now sets flush-and-exit instead of abort: the captured backlog is written whenever the stall clears rather than discarded; join-timeout on a slow-but-progressing drain no longer sets finalize_wedged (false-positive fail-fast aborted whole runs over stores that finished fine). - Non-abort incomplete seals no longer stamp aborted=true: ZarrWriter.abort(mark_aborted=False, extra_attrs=...) writes incomplete=True with error/drop/captured counts so tooling can tell "user pressed Stop" from "finished with missing planes". Wedge-style tests join their drain threads before returning (the class-level ZarrWriter monkeypatches made leftover daemon drains call the next test's stubs — order-dependent flakes).

charset=UTF-8 Content-Transfer-Encoding: 8bit R6-R8, R10-R13 (R1-R5+R9 landed in the previous commit): - toggleAcquisitionStart shares the tab-needs-well-selector decision with onTabChanged (_tab_uses_well_selector): finishing a Record + Z-Stack acquisition no longer hides the well selector permanently, and transient acquisition hides no longer overwrite the user's remembered visibility preference. - Entering the Record + Z-Stack tab rebuilds the FOV grid (regions were cleared but never rebuilt), and well clicks on this tab rebuild it too (wellplate's handler early-returns for other tabs), so the navigation viewer shows scan coverage before Start. - refresh_channel_list warns loudly when the previously selected recording channel vanishes after an objective/profile change (the combo silently swapped to the first channel while the exposure/gain/ illumination spins kept the old channel's values). - acquisition_channels.yaml dedupes channels by name (recording entry wins) — a channel used by both phases appeared twice. - ContinuousFrameSource(already_configured=True): record() already probes CONTINUOUS mode + frame rate for the achievable fps, so the source no longer repeats both per FOV (mode switch + strobe/exposure re-send on toupcam); the clamped rate is re-applied when it differs. - _populate_channel_combo(names=...) shared by construction and refresh (two divergent population paths). - _cleanup_common closes recordZStackController with a 30s budget — 5s let app teardown race a worker still unwinding on a slow disk (partial fix; closeEvent acquisition guard remains a follow-up). TDD: 4 new tests watched failing first (well-selector restore test rides in the CI-only gui test file).

charset=UTF-8 Content-Transfer-Encoding: 8bit Mirrors WellplateMultiPointWidget's XY/Time tab row (checkbox + combo in a colored frame that shows/hides its controls), skipping Z since this widget's own Z-Stack phase group already covers z-stacking: - checkbox_xy + combobox_xy_mode now offer two real modes: "Select Wells" (today's tile-over-selected-wells behavior, kept as default) and "Current Position" (new: single FOV at the live stage position, bypassing well selection — validate() no longer requires wells in this mode). Unchecking XY forces Current Position and disables the combo; re-checking restores the previous mode, mirroring WellplateMultiPointWidget exactly. - checkbox_time wraps Nt/dt: unchecked forces a single timepoint and hides the controls, restoring the previous Nt/dt on re-check. - checkbox_laser_af relocated into this row as a plain checkbox, matching how WellplateMultiPointWidget places its own Laser AF toggle. Channel-add now seeds from the channel's own configured settings (via a new _channel_settings/_find_channel lookup) instead of hardcoded 50ms/0 gain/50%, for both the z-stack "+ Add" button and the recording-channel combo (including its initial row and on selection change). Layout: removed the channel tables' fixed 530px width (fighting against whatever width the main window happens to lock in for this tab) in favor of a responsive fill plus tightened field widths throughout, so the panel no longer needs a horizontal scrollbar. Z-Stack channel table now spans the group's full width to match the Recording table. Z-Stack channel names get a tooltip showing the full name since the Channel column truncates. ~20 new tests covering the XY/Time toggling, mode switching, channel seeding, and table behavior. --- software/control/widgets.py | 351 ++++++++++++++++---- software/tests/test_record_zstack_widget.py | 343 +++++++++++++++---- 2 files changed, 563 insertions(+), 131 deletions(-) diff --git a/software/control/widgets.py b/software/control/widgets.py index ba6d18f12..9acecd9ec 100644 --- a/software/control/widgets.py +++ b/software/control/widgets.py @@ -16244,8 +16244,8 @@ def _build_wells_fov_group(self) -> QGroupBox: vbox.setSpacing(6) # Consistent widths so label+field pairs line up cleanly across rows. - field_w = 90 # spinbox / combo width - pair_gap = 14 # horizontal gap between adjacent label+field pairs + field_w = 70 # spinbox / combo width + pair_gap = 6 # horizontal gap between adjacent label+field pairs def _pair_label(text: str) -> QLabel: lbl = QLabel(text) @@ -16254,10 +16254,53 @@ def _pair_label(text: str) -> QLabel: # First-column labels share a width so the first field of each row aligns # (sized for the wider "Overlap:" label). - first_label_w = 66 + first_label_w = 52 + + # --- XY / Time tabs row: mirrors WellplateMultiPointWidget's XY/Z/Time + # tabs (checkbox + combo in a frame that highlights when active).

059/115] fix: RecordZStackMultiPointWidget._apply_yaml_settings channel/time bugs Task review findings (PR #564): - Recording channel exp/gain/illum spinboxes were set unconditionally even when the YAML channel name wasn't found in the current combo, silently pairing a stale display name with mismatched numeric settings. Now only applied when found; a warning is logged otherwise and the row is left untouched. - checkbox_time was never synced from yaml_data.nt, leaving the Time checkbox unchecked (and time_controls_frame hidden) after loading a multi-timepoint YAML even though entry_Nt/entry_dt were updated. Now checkbox_time is blocked/set like the sibling WellplateMultiPointWidget, and the frame's visibility is refreshed directly in the finally block (not via _on_time_toggled, which would clobber the just-loaded Nt/dt via its stored/restore side effect).

Add two buttons to the output group that allow users to save and load full acquisition settings via file dialogs: - "Save Settings…" button calls _on_save_settings_clicked to save current widget state (calls _update_scan_regions, builds parameters, and calls _save_record_zstack_yaml) - "Load Settings…" button calls _on_load_settings_clicked to load from a file (calls the mixin's _load_acquisition_yaml) Both buttons use QFileDialog for file selection. Error handling shows warning dialog on save failure. Tests verify button clicks are wired correctly and call underlying save/load machinery.

Load test now writes a real, valid record_zstack YAML file and only mocks QFileDialog.getOpenFileName, so the full parse_acquisition_yaml -> validate_hardware -> _apply_yaml_settings chain is actually exercised instead of a hand-rolled substitute. Also drops a redundant local `from unittest.mock import patch` now that the load test no longer needs to patch the instance method.

Answering No aborts the start and re-unchecks the button; the dialog is skipped entirely when the Recording phase is disabled. The summary's Z offset uses the same effective-value logic as build_parameters() (0.0 when Laser AF is off) so it can never show a stale value from the hidden entry_recording_bottom_z field that doesn't match what actually runs. Also fixes entry_recording_bottom_z's tooltip, which stayed frozen at "Bottom plane offset relative to the Z reference" even after Nz dropped to 1 and the caption switched to "Z offset:" -- it now tracks the same multi/ single wording as the label. --- software/control/widgets.py | 30 ++++ software/tests/test_record_zstack_widget.py | 188 ++++++++++++++++++++ 2 files changed, 218 insertions(+) diff --git a/software/control/widgets.py b/software/control/widgets.py index 7f1d4c716..1189db6a4 100644 --- a/software/control/widgets.py +++ b/software/control/widgets.py @@ -16942,6 +16942,9 @@ def _update_recording_planes_ui(self) -> None: self.label_recording_bottom_z.setVisible(use_af) self.entry_recording_bottom_z.setVisible(use_af) self.label_recording_bottom_z.setText("Bottom Z offset:" if multi else "Z offset:") + self.entry_recording_bottom_z.setToolTip( + "Bottom plane offset relative to the Z reference" if multi else "Offset relative to the Z reference" + ) def _add_zstack_channel_row( self, name: str, exposure: float = 50.0, gain: float = 0.0, illumination: float = 50.0 @@ -17398,6 +17401,9 @@ def toggle_acquisition(self, pressed: bool) -> None: On start (pressed=True): - validate(); show QMessageBox.warning and un-check button on failure. + - if Recording is enabled, show a QMessageBox.question confirming the + plane-count/Z-range/per-FOV-duration summary; un-check button and + abort if the user answers No. - emit signal_acquisition_started(True) so gui_hcs can lock down the UI. - call recordZStackController.run_acquisition(self.build_parameters()). @@ -17425,6 +17431,30 @@ def toggle_acquisition(self, pressed: bool) -> None: QMessageBox.warning(self, "Invalid Parameters", error) return + # One last look at the recording plane summary before starting. + # bottom must use the same effective-value logic as build_parameters() + # (the field is hidden and stale when Laser AF is off, so a hidden + # value must not silently apply -- see the comment there). + if self.checkbox_recording.isChecked(): + nz = self.entry_recording_Nz.value() + bottom = self.entry_recording_bottom_z.value() if self.checkbox_laser_af.isChecked() else 0.0 + per_fov_s = nz * self.entry_duration.value() + if nz > 1: + top = bottom + (nz - 1) * self.entry_recording_dz.value() + summary = f"{nz} planes: {bottom:+.1f} … {top:+.1f} µm rel. reference — {per_fov_s:.1f} s/FOV" + else: + summary = f"1 plane @ {bottom:+.1f} µm — {per_fov_s:.1f} s/FOV" + reply = QMessageBox.question( + self, + "Confirm Recording", + f"Recording: {summary}\n\nStart acquisition?", + QMessageBox.Yes | QMessageBox.No, + QMessageBox.Yes, + ) + if reply != QMessageBox.Yes: + self.btn_startAcquisition.setChecked(False) + return + # Refresh the per-well FOV grid before building parameters so the # scan regions reflect the current overlap/shape/region-size settings. self._update_scan_regions() diff --git a/software/tests/test_record_zstack_widget.py b/software/tests/test_record_zstack_widget.py index cbd267a39..e42ee1c4c 100644 --- a/software/tests/test_record_zstack_widget.py +++ b/software/tests/test_record_zstack_widget.py @@ -25,6 +25,7 @@ from unittest.mock import MagicMock, patch import pytest +from qtpy.QtWidgets import QMessageBox from control.widgets import _validate_record_zstack_params @@ -583,6 +584,193 @@ def test_toggle_acquisition_stop_calls_request_abort(qtbot, simulated_widget_dep ctrl.run_acquisition.assert_not_called() +# --------------------------------------------------------------------------- +# Confirmation dialog: recording plane summary shown before Start proceeds +# --------------------------------------------------------------------------- + + +def _make_valid_recording_widget(qtbot, deps, *, laser_af=False): + """Return a widget pre-configured for a valid recording-only acquisition. + + Recording is enabled, Z-Stack is disabled.

On the ToupTek the PRECISE_FRAMERATE option can't be read (E_UNEXPECTED), so set_frame_rate() fell back to 1000/get_total_frame_time(). get_total_frame_time() is the *sequential* software/hardware-trigger period (readout + trigger_delay + exposure) — ~2x the true continuous free-run period — so recordings were capped at roughly half the camera's real rate: a 20 or 30 fps request clamped to ~14 fps (and dropping exposure didn't help, since trigger_delay grows to keep the total pinned). Add ToupcamCamera._continuous_max_framerate() = 1000/max(readout, exposure), where readout = strobe_time_us (the exposure-independent sensor readout period), and return it from set_frame_rate()'s fallbacks. record()'s existing "honor the requested fps unless the camera can't reach it" logic then works: requests up to the readout ceiling are honored; higher requests clamp to the true max. Triggered-mode timing is untouched — get_strobe_time / get_total_frame_time / _calculate_strobe_info are unchanged; only set_frame_rate (continuous-only) and the new helper change. Verified on a real ITR3CMOS26000KMA: 25 fps x 5 s -> 125 frames (honored); 30 fps x 4 s -> 112 frames at 28.04 fps (the true readout max), where the old code produced ~56 at the bogus 14 fps.

Added a regression test. - test_copy_from_live_uses_selected_channels_own_settings didn't actually exercise the button's click handler, since selecting the channel via setCurrentText() already auto-seeds the same target values through _on_recording_channel_changed. Overwrite the spinboxes before clicking so the assertions can only pass if the click handler itself re-applies them. - Factored the duplicated 3-line header-unbold snippet (recording + z-stack tables) into a shared _set_header_not_bold() helper. - recording_channel_table's tightened fixed-height padding used a bare "+2" magic number; use 2 * frameWidth() (the table's actual top+bottom border) instead, so it stays correct if the frame style ever changes. --- software/control/widgets.py | 50 ++++++++++++++------- software/tests/test_record_zstack_widget.py | 45 +++++++++++++++++++ 2 files changed, 79 insertions(+), 16 deletions(-) diff --git a/software/control/widgets.py b/software/control/widgets.py index f29af0d68..5504a4c6b 100644 --- a/software/control/widgets.py +++ b/software/control/widgets.py @@ -16162,6 +16162,13 @@ def _set_layout_widgets_visible(layout, visible: bool) -> None: _set_layout_widgets_visible(sub_layout, visible) +def _set_header_not_bold(header: QHeaderView) -> None: + """Un-bold a QHeaderView's section labels (Qt's default header font is bold).""" + font = header.font() + font.setBold(False) + header.setFont(font) + + class RecordZStackMultiPointWidget(AcquisitionYAMLDropMixin, QFrame): """Single-column 'Record + Z-Stack' acquisition tab (Option-A layout). @@ -16574,9 +16581,7 @@ def _build_recording_group(self) -> QFrame: hdr.setSectionResizeMode(2, QHeaderView.ResizeToContents) hdr.setSectionResizeMode(3, QHeaderView.ResizeToContents) hdr.setSectionResizeMode(4, QHeaderView.ResizeToContents) - hdr_font = hdr.font() - hdr_font.setBold(False) - hdr.setFont(hdr_font) + _set_header_not_bold(hdr) self.recording_channel_table.verticalHeader().setVisible(False) self.recording_channel_table.setSelectionBehavior(QAbstractItemView.SelectRows) # Force the 5 columns to fit (Channel truncates via Stretch) instead of @@ -16642,10 +16647,14 @@ def _build_recording_group(self) -> QFrame: # Size the table to exactly fit the header + single row, now that the # cell widgets (which are taller than plain text) are in place — doing # this before the widgets were added left a fixed height too tall, - # showing empty space below the row. + # showing empty space below the row.

charset=UTF-8 Content-Transfer-Encoding: 8bit Starting a recording while Live ran in SOFTWARE-trigger mode aborted the run on real hardware. _probe_frame_shape() sized the recording dataset by sending a software trigger, but Live's last trigger was still outstanding (get_ready_for_trigger() == False), so send_trigger() was rejected ("trigger too early"). The probe then fell back to get_resolution() — the raw binned sensor size (3104x2084) — while the camera delivers cropped 2084x2084 frames, so every write_frame failed with a dimension-alignment error and the store sealed incomplete, fail-fasting the whole acquisition. Probe in CONTINUOUS mode instead — the same mode recording uses — and read one free-run frame (no send_trigger, so trigger readiness can't block it); the probed shape is then exactly what recording writes. On a genuine probe failure, abort with a clear error instead of sizing from get_resolution() and grinding out a blank, incomplete recording. Also fix SimulatedCamera.read_camera_frame() to wait for a frame (matching the real camera / AbstractCamera contract) rather than returning None before the first CONTINUOUS frame — otherwise the continuous probe gets no frame in sim. Verified on a real ITR3CMOS26000KMA: the continuous probe returns (2084, 2084) (matching delivery) vs get_resolution()'s (3104, 2084), and get_ready_for_trigger() is False right after a software trigger (reproducing the reject). New tests cover the probe using CONTINUOUS/never triggering and aborting (not get_resolution) on no frame.

The conflict resolutions those merges carried are not reproducible commit-by-commit, so replaying the older side of each pair silently reverted work that was already settled. This restores the tree to exactly what `git merge upstream/master` produces from the pre-rebase tip, i.e. the reviewed content of the PR: - multi_point_worker.py — keep `_abort_cause` / `_abort_due_to_error()` / `_run_state_beat()` hoisted into MultiPointWorkerBase, and the frame callback's `_abort_due_to_error()` calls, rather than the pre-merge `request_abort_fn()` form that the extract-base commit had moved verbatim. - widgets.py, acquisition_yaml_loader.py, record_zstack_controller.py — keep the multi-plane recording fields (Nz / dz / bottom-Z offset) that superseded the single `recording_z_offset_um`, plus the `_update_recording_planes_ui()` resync after a YAML load. - gui_hcs.py — drop the `emit_selected_channels()` call that a later commit had already removed in favour of `_tab_uses_well_selector()`. - tests — matching updates and test ordering. Verified: this branch's tree is now byte-identical to the clean merge of upstream/master into the pre-rebase tip (0afae24a). --- software/control/acquisition_yaml_loader.py | 8 +- software/control/core/multi_point_worker.py | 60 +++-- .../control/core/record_zstack_controller.py | 17 +- software/control/gui_hcs.py | 2 - software/control/widgets.py | 14 +- .../control/test_HighContentScreeningGui.py | 56 ++--- .../control/test_acquisition_yaml_loader.py | 8 +- .../tests/core/test_record_zstack_worker.py | 215 +++++++++++++++++- software/tests/test_record_zstack_widget.py | 8 +- 9 files changed, 322 insertions(+), 66 deletions(-) diff --git a/software/control/acquisition_yaml_loader.py b/software/control/acquisition_yaml_loader.py index 2ecb4c889..a7f7d018b 100644 --- a/software/control/acquisition_yaml_loader.py +++ b/software/control/acquisition_yaml_loader.py @@ -80,7 +80,9 @@ class RecordZStackYAMLData: recording_channel: Optional[Dict] = None fps: float = 10.0 duration_s: float = 1.0 - recording_z_offset_um: float = 0.0 + recording_bottom_z_offset_um: float = 0.0 + recording_nz: int = 1 + recording_dz_um: float = 1.0 zstack_enabled: bool = False zstack_channels: List[Dict] = field(default_factory=list) @@ -120,7 +122,9 @@ def _parse_record_zstack_yaml_data(data: dict, acq: dict) -> RecordZStackYAMLDat recording_channel=recording.get("channel"), fps=recording.get("fps", 10.0), duration_s=recording.get("duration_s", 1.0), - recording_z_offset_um=recording.get("z_offset_um", 0.0), + recording_bottom_z_offset_um=recording.get("bottom_z_offset_um", 0.0), + recording_nz=recording.get("nz", 1), + recording_dz_um=recording.get("dz_um", 1.0), zstack_enabled=z_stack.get("enabled", False), zstack_channels=z_stack.get("channels", []), z_min_um=z_stack.get("z_min_um", -3.0), diff --git a/software/control/core/multi_point_worker.py b/software/control/core/multi_point_worker.py index 99b538b07..550fe3a6c 100644 --- a/software/control/core/multi_point_worker.py +++ b/software/control/core/multi_point_worker.py @@ -114,6 +114,7 @@ def __init__( self.callbacks: MultiPointControllerFunctions = callbacks self.abort_requested_fn: Callable[[], bool] = abort_requested_fn self.request_abort_fn: Callable[[], None] = request_abort_fn + self._abort_cause = None # set to "error" by auto-abort paths (timeout / failed jobs) # Optional SlackNotifier — subclasses set the real one if present. self._slack_notifier = None @@ -367,6 +368,37 @@ def shutdown_runner(job_runner, timeout): except Exception as e: self._log.error(f"Error closing backpressure controller: {e}") + def _create_in_process_zarr_runner(self, zarr_writer_info: Optional[ZarrWriterInfo]) -> InProcessZarrRunner: + """Zarr is saved in this process (see in_process_zarr_runner.py); the runner shares our backpressure counters.""" + runner = InProcessZarrRunner( + zarr_writer_info=zarr_writer_info, + bp_values=( + self._backpressure.pending_jobs_value, + self._backpressure.pending_bytes_value, + self._backpressure.capacity_event, + ), + ) + runner.start() + return runner + + def _abort_due_to_error(self) -> None: + """Abort the run due to an internal error (vs a user abort). + + The worker only ever aborts itself on error conditions; user aborts arrive + via the external abort flag.

Reuse — one copy instead of two: - New PrewarmedJobRunnerSlot (acquisition_setup.py) owns the warm-up/consume/ re-warm/shutdown lifecycle; MultiPointController and RecordZStackController both delegate to it instead of carrying verbatim copies of the trio. - MultiPointWorkerBase gains _create_backpressure, _channel_zarr_metadata and _adopt_or_create_job_runner; MultiPointWorker.__init__ and RecordZStackWorker._setup_zstack_job_runner now share the backpressure construction, channel-metadata extraction, and the adopt-or-create runner dance (incl. the hung-warmup shutdown path) they had each re-implemented. - _move_z_to_offset and both phases' Z-restores delegate to the inherited move_to_z_level (whose blocking stage move already includes the MCU wait). - _parse_well_name keeps its strict regex but delegates the bijective base-26 math to mosaic_utils.parse_well_id (was a third copy of the row arithmetic). - _build_objective_info uses compute_pixel_size_um instead of an inline copy. - parse_acquisition_yaml calls _parse_camera_binning instead of keeping the identical inline block 80 lines below the helper. - QtRecordZStackController builds callbacks via dataclasses.replace(NoOpCallbacks, ...) instead of a 7-lambda copy; comment corrected (the base machinery does emit other callbacks — deliberately dropped, no live-display routing for this mode yet). - _browse_saving_dir now persists via save_last_used_saving_path, matching the sibling widgets it re-implements (the widget already read the value at init). Altitude — validation and public surfaces: - validate_record_zstack_params moved from widgets.py to record_zstack_controller.py beside the params dataclass and geometry helpers it validates (widget's validate() delegates; controller-side enforcement in run_acquisition deliberately NOT added — zero-FOV runs are a tested contract). - The confirm-recording dialog derives its plane range from recording_plane_offsets_um — the same helper the worker records with. - gui_hcs.onTabChanged calls the widget's public on_well_selection_changed() instead of reaching into _update_scan_regions(). Efficiency — per-FOV and hot-path waste: - The achievable-fps probe runs once per acquisition (exposure is fixed, the clamp can't change between FOVs); later FOVs just re-assert the cached rate after their mode switch. The old "re-apply clamped rate" block — a hardware no-op on every camera implementation — is gone, as is the per-FOV repeat of the clamp warning. - zstack() skips set_trigger_mode(SOFTWARE) when the mode is already SOFTWARE (every FOV after the first): the camera side is re-asserted by record()'s finally, so the repeat was a pure MCU round trip. - RecordZStackController consumes the pre-warmed runner only when the z-stack phase will dispatch jobs; recording-only runs no longer orphan a runner and spawn a replacement subprocess for nothing. - StreamingCapture resolves stop_condition.expected() once at construction instead of hasattr-probing on every hot-path frame callback. Simplification — dead state and derivable state: - _zstack_channel_names is now a property derived from the table (single source of truth); add/remove row no longer double-bookkeep a parallel list. - The recording-row accessors read the stored spinbox/combo attributes directly; the cellWidget() lookups and unreachable fallbacks are gone. - Timepoint pacing computes the deadline once in _pace_timepoint and passes it to _wait_for_dt; the never-None _acq_start_time fallbacks are gone, as is zstack()'s redundant re-write of self.time_point. Tests updated mechanically (validator import/patch target, _wait_for_dt deadline arg, mock controller slot). Full battery matches the pre-cleanup baseline exactly: worker 32 passed + the 2 pre-existing smoke failures, widget 100, streaming/fps/yaml 165, backpressure+laser-AF 103, GUI 7, control/core 285, MultiPointController/Worker 9.

Unpinned binning. The test harness pins crop_width/crop_height and asserts frames of exactly that size, but SimulatedCamera reports resolution as crop/binning — and machine configs that default the camera model to 2x2 binning (e.g. GXIPY MER2-1220) silently halve every frame, failing the shape asserts. _build_simulated_microscope now pins binning to 1x1. CI never saw this because importorskip("tensorstore") skips both tests there. 2. Dirty fork -> wedged JobRunner. The controller smoke's pre-warmed JobRunner is forked after the worker smoke has already done in-process tensorstore I/O (its RecordingWriter); the child inherits tensorstore's initialized global state without its worker threads and deadlocks inside ts.open() on its first SaveZarrJob. Pre-existing: the parent sat ~2 minutes in bounded waits before failing, post-binning-fix it exceeded 5. The controller smoke now runs its jobs in-process (USE_MULTIPROCESSING=False, the file's existing pattern); the forked-subprocess path stays covered by the worker smoke, whose fork happens before any in-process tensorstore use. 3. In-process SaveZarrJob was unrunnable. The frame callback's non-multiprocessing fallback calls job.run() directly, but only JobRunner.dispatch() injected zarr_writer_info — so ANY ZARR_V3 acquisition with USE_MULTIPROCESSING off aborted on its first frame ("requires zarr_writer_info but it is None"). Workers now keep their ZarrWriterInfo and the fallback injects it before job.run(), exactly as the error message prescribes. tests/core/test_record_zstack_worker.py: 34 passed (was 32 passed / 2 failed), and the file drops from ~175s to ~64s — the wedged child's bounded waits are gone. Full battery (MultiPoint controller/worker, per-region laser AF, backpressure, streaming capture, widget, camera fps, HCS GUI): all green.

From e26c76df01d159d078728a692ca5c7b0c6241b3d Mon Sep 17 00:00:00 2001 From: Hongquan Li Date: Tue, 8 Sep 2026 01:24:32 -0700 Subject: [PATCH 091/115] fix(camera): apply the toupcam PRECISE_FRAMERATE hint while the stream is stopped, bound it by exposure Bench-tested on an ITR3CMOS26000KMA (camera-only bench, everything else simulated). Two things the simulation could not show: 1. The MIN/MAX_PRECISE_FRAMERATE *reads* fail with E_UNEXPECTED whenever the pull-mode stream is stopped (Toupcam_Stop), but the PRECISE_FRAMERATE *write* is accepted and takes effect on the next Start. RecordZStackWorker always stops the stream (frame-shape probe) before record() calls set_frame_rate, so the range read failed every time, the hint was silently dropped, and the sensor free-ran at 28 fps with the RecordingRouter downsampling in software (2.8x the frame traffic, +-18 ms slot jitter). The existing test even pinned this as "option unavailable on this camera". Now the range is read once at construction (stream just started) and on every later successful read, and set_frame_rate falls back to the cached range while stopped and always writes the option. Verified: 10 fps requested -> exactly 30 frames / 3 s delivered, 100.0 ms spacing. 2. MAX_PRECISE_FRAMERATE ignores the exposure time: at 100 ms exposure the camera still reports 28 fps max, and set_frame_rate(30) returned 28 while the sensor delivered 10 fps. The worker sizes the dataset from that return value, so the recording would have sealed incomplete with blank planes. The returned rate is now min(clamped precise rate, exposure/readout- limited continuous max): 100 ms @ 30 fps requested -> 10.0.

Before: 20 fps was the ceiling — 25 fps overran the 2 GB queue after ~28 s and fail-fast aborted, and the camera's 28 fps maximum never sealed complete. After: every mode records at the camera maximum with complete stores (6.8 fps at 1x1/16-bit, 28 at 2x2/16-bit, 37 at 2x2/8-bit, 63 at 3x3/16-bit, 108 at 3x3/8-bit; 240 MB/s sustained). Two independent limits fell: 1. RecordingWriter drained synchronously: ZarrWriter.write_frame() blocks on every future, so encode / file create / write / fsync never overlapped and the drain topped out at ~25 frames/s of 8 MB frames (~10 with the camera thread competing). ZarrWriter gains submit_frame() (returns the write future; write_frame() is now submit + wait) and the drain keeps up to max_inflight=8 submissions outstanding, reaping the oldest before each new one and every one before sealing, so errors are still counted and abort()/finalize() never race in-flight I/O. Micro-benchmark: 25 -> 120+ frames/s at 4 in flight with fsync semantics unchanged. 2. RecordingRouter mapped frames to the slot nearest their host arrival time and rejected "duplicates". At the camera's maximum the sensor free-runs ~2% off the nominal rate, so a frame every ~25-50 was rejected (807/840, 834/840) and each store sealed incomplete; a GUI repaint holding the GIL for >50 ms did the same at 10 fps. The worker now tells the router when the camera reported it will deliver at or below the requested rate (it paces itself to the hint, or the request is its maximum): every frame is then wanted and slots are filled sequentially, never rejected. Only a gap >= max(1.75 periods, 100 ms) is a stall (logged, holes kept). Cameras that report a HIGHER free-run rate keep the old downsampling regime, test-pinned.

hint re-applied once the stream runs Follow-up to the earlier PRECISE_FRAMERATE fix, from bench runs across binning / bit-depth modes on an ITR3CMOS26000KMA: - The (min, max) range depends on resolution and bit depth (2x2 16-bit: 1.9-28 fps; 3x3 8-bit: 4.8-108.5 fps). The cached range is now keyed on (width, height, bytes/pixel) and dropped on a mode change, and refreshed every time the pull-mode stream starts, so a stopped-stream set_frame_rate() after a binning change no longer clamps the new mode to the old maximum (3x3 modes were capped at 28 fps). - With no cached range the request is bounded by the readout-limited maximum (within 1.5% of the SDK's value in every mode measured) and written anyway. The SDK validates a stopped-state write against the range of the mode it LAST streamed in and, on rejection, keeps the previous pacing (no free-run fallback), so ContinuousFrameSource.start() now re-applies the hint right after start_streaming(), where the range is always current. The pre-start probe still sizes the dataset.

RecordingRouter now measures the delivered spacing ((last - first) / slots spanned); StreamingCapture warns and hands it to the writer when it deviates >2% from nominal, and the seal (finalize or incomplete/abort) rewrites _squid.time_increment_s and the OME t-axis scale with it, keeping nominal_time_increment_s alongside. Within 2% (host-timestamp jitter) the nominal value is kept. - The stall warning logged from the hot camera-callback thread on every stall: now the first and every 50th, plus a per-run summary after the source stops (stall/hole counts on the router). - ToupcamCamera._start_raw_camera_stream refreshes the PRECISE_FRAMERATE range only for a CONTINUOUS stream (a trigger-mode stream from the z-stack phase must not overwrite the free-run range), outside the Start try block, and _refresh_precise_framerate_range swallows any exception — nothing there may desync _raw_camera_stream_started from the SDK stream. - RecordZStackController.run_acquisition rejects recording_enabled with recording_channel=None: the worker probes the fps once and re-applies the recording channel per FOV, so without one the z-stack's last channel would set later FOVs' exposure and the cached rate would be wrong. Bench re-check on the ITR3CMOS26000KMA: 10 fps -> 100/100 and 28 fps max -> 840/840 x 2 FOV, both complete, nominal spacing kept (no deviation warning).

full-frame recordings were clean. Reproduced on the second camera and isolated to two SDK behaviours: - With a ROI, a PRECISE_FRAMERATE above the full-frame maximum written while stopped is accepted but re-clamped to that old maximum at Start (300 written, 280 read back), so the running-state re-apply in ContinuousFrameSource.start is the only way to reach the rate the ROI exists for (it did: 30 and 40 fps recorded). - A write into the running stream corrupts the frame integrating at that moment (1.8-3.6x over-exposed on the dim camera, saturated on the bright one), delivered as the first frame after the write. Full-frame is immune. Fix: the driver skips the running write when the camera already reports the value (no glitch in the common case) and timestamps the writes it does make (frame_rate_hint_live_write_ts); ContinuousFrameSource then discards frames delivered within one period (+20 ms) of that write - the corrupted frame and at most one clean in-flight one - before routing. Verified on camera 2 for full frame, 1600 and 600 rows, with live view continuous / software trigger / off: first frames identical to the rest; 1-2 frames discarded only when a ROI forced the live write, none otherwise.

It lands in params.effective_fps and in acquisition.yaml (recording.effective_fps next to the requested fps), and the confirmation dialog shows the same number. The worker applies that rate at each FOV; the camera's reply only decides pacing vs. downsampling, and a camera reporting >1% less than resolved is logged and honoured as a safety net. Previously the worker discovered the achievable rate at the first FOV, so the settings file could not record it.

Replaying the older side of each conflicting pair reverted master-side work in the files both sides touch. This restores the tree to exactly what `git merge origin/master` produces from the pre-rebase tip (59de99ae), with the two conflicts that merge has resolved as follows: - multi_point_worker.py - master (#652) passes `save_settings` to every save job from `_create_job()`, a method this branch had moved into MultiPointWorkerBase. The settings snapshot now lives in the base `__init__` and the base `_create_job()` passes it, so the Record + Z-Stack worker's z-stack jobs get the same settings as multipoint's. - gui_hcs.py - master (#627) removed the napari live view. Keep master's display wiring and add the record-zstack preview connection to the one remaining (pyqtgraph) path; the napari-live variant of it is gone. Also restored, from the dropped merge commit: - acquisition_setup.py, multi_point_controller.py - `add_timestamp` on `create_experiment_dir()` / `start_new_experiment()` (fluidics runner). - gui_hcs.py - `_setup_fluidics_widgets()` call; no refresh of the removed `multiPointWithFluidicsWidget`. - acquisition_yaml_loader.py - record_zstack YAMLs read wellplate-style regions from coordinates.csv. - tests - matching imports and path-separator handling. Verified: this branch's tree is byte-identical to the merge of origin/master into the pre-rebase tip.

Acquisition behavior, files written and metadata are unchanged. Duplication - widgets: one builder for the channel table and one for its exposure / gain / illumination editors, used by the recording row and the z-stack rows; one lookup of a z-stack row by channel name; one setter for the recording row; the XY / Time tab styles are built from their colour. - zarr_writer: finalize() and abort() share one read-modify-write of zarr.json (_seal_metadata). The two copies had drifted: abort() assigned the attributes under the time-increment branch. - cameras: the free-run maximum frame rate is computed in one place per camera class (get_max_frame_rate / _continuous_max_framerate) and set_frame_rate uses it. - streaming_capture: the writer's drop and write-error accounting is written once; finalize_wedged reads the event that was set with it. - worker: the once-per-acquisition frame-rate setup of record() is its own method (_apply_recording_rate). - tests: the two preview tests use the harness the other worker tests use. Probing of members that always exist - StreamingCapture calls its router, stop condition and writer directly instead of looking for their members with getattr / hasattr; the test writers implement the members the real writer has. - worker, controller, widget and gui_hcs read LiveController, Microscope, ObjectiveStore and ScanCoordinates attributes directly. Dead code - RecordingRouter.paced (never read) and its two stall parameters (never passed; now class constants); the controller's _worker attribute; the worker's fallback channel name and colour for a recording without a channel, which the controller rejects; re-assignments of values the base class already set; unused imports in record_zstack_worker. One efficiency change - A well selection change keeps the wells already tiled and tiles only the new ones, as WellplateMultiPointWidget does, instead of tiling every selected well again on each step of a drag-select. Changes of size, overlap, shape or mode, and the start of an acquisition, still rebuild. Comments and docstrings that described an earlier state of the code are brought up to date.

The rule that shows the Z offset with Laser AF and dz with Nz > 1 (_update_recording_planes_ui) set those fields visible without looking at the phase checkbox, so ticking Laser AF brought the Z offset back inside the collapsed section. Loading settings with the recording phase off and Laser AF on (or Nz > 1) did the same, because the rule runs after the collapse there. The rule now shows a field only while the Recording phase is checked. Expanding the section shows the fields the rule placed in its rows, as before. Tests (both failed before the fix): toggling Laser AF and Nz with the section collapsed, then expanding it; loading settings with the recording phase off.

the abort that silently lost the z-stack of acquisition 3+ cannot happen. RecordZStackController drops its pre-warm slot (no subprocess to warm), the worker polls the save results after every FOV and ends the run as an error on a failed write, and the base worker initializes _run_state_fatal so a subclass's _finish_jobs can seal a crashed run's stores as aborted. The USE_MULTIPROCESSING=False workarounds in the tests, which only existed to dodge the fork abort, are gone.

the worker's crash path tags the error cause. - record() and zstack() start their cleanup regions before the first hardware step, so a failed illumination enable or callback registration still restores Z, the camera mode and the stream state.
