From da8087d142ae401aeaf181fe1ca7cf728711453f Mon Sep 17 00:00:00 2001 From: Mike McCann Date: Thu, 23 Jul 2026 20:47:37 -0700 Subject: [PATCH 1/3] Detect stale and incomplete LRAUV deployment plot outputs before skipping reprocessing _deployment_has_outputs() previously only checked for the presence of any output PNG, so a new .nc log file added to an already-processed deployment (or a plot kind that silently failed to generate) was never picked up by subsequent --last_n_days runs. It now also requires every output PNG to have its HTML sibling, every source nc file to be no newer than the existing outputs (via local stat or an HTTP Last-Modified check), and every plot kind with per-log data to have a matching combined-deployment PNG. --- src/data/lrauv_deployment_plots.py | 159 +++++++++++++++++++++--- src/data/test_lrauv_deployment_plots.py | 113 ++++++++++++++++- 2 files changed, 248 insertions(+), 24 deletions(-) diff --git a/src/data/lrauv_deployment_plots.py b/src/data/lrauv_deployment_plots.py index 395b156..dc9bce4 100755 --- a/src/data/lrauv_deployment_plots.py +++ b/src/data/lrauv_deployment_plots.py @@ -30,6 +30,7 @@ from email.mime.image import MIMEImage from email.mime.multipart import MIMEMultipart from email.mime.text import MIMEText +from email.utils import parsedate_to_datetime from pathlib import Path from zoneinfo import ZoneInfo @@ -186,9 +187,130 @@ def _concat_datasets(self, nc_files: list[Path | str]) -> xr.Dataset | None: self.logger.info("Concatenating %d dataset(s) via xr.concat", len(datasets)) return xr.concat(datasets, dim="time", join="outer") - def _deployment_has_outputs(self, deployment_dir: Path, plot_name_stem: str) -> bool: - """Return True if any per-deployment PNG already exists in *deployment_dir*.""" - return any(deployment_dir.glob(f"{plot_name_stem}_*.png")) + def _local_path_for_nc_url(self, nc_url: str) -> Path | None: + """Return a local filesystem Path for an OPeNDAP nc URL, if it resolves + under LRAUV_VOL or BASE_LRAUV_PATH, else None.""" + opendap_prefix = LRAUV_OPENDAP_BASE.rstrip("/") + "/" + if not nc_url.startswith(opendap_prefix): + return None + rel = nc_url[len(opendap_prefix) :] + for local_base in (Path(LRAUV_VOL), BASE_LRAUV_PATH): + candidate = local_base / rel + if candidate.exists(): + return candidate + return None + + def _nc_file_mtime(self, nc_file: Path | str) -> float | None: # noqa: PLR0911 + """Return the modification time (epoch seconds) of one nc file, local or remote. + + Tries a local stat first (direct Path, or an OPeNDAP URL that resolves + under LRAUV_VOL/BASE_LRAUV_PATH), then falls back to an HTTP HEAD request + against the plain (non-OPeNDAP) BASE_LRAUV_WEB URL for its Last-Modified + header.
