PDFstream Change Log

v0.6.3

Fixed:

  • remove last rogue deprecated np.bool

v0.6.2

Fixed:

  • The data folder is now added in the package release.
  • The file name render returns the modified documents and the following callbacks use the returned documents instead of the input ones.

v0.6.1

Added:

  • Add the options publish to disable publishing to the proxy.

Fixed:

  • Fix the "python list doesn't have shape" bug when loading masks in python lists.
  • Fix the databroker v2.0 API bugs in tests.

v0.6.0

Added:

  • Add new callbacks in the callback package for the analysis, serialization and visualization for the new data structure from the new xpdacq.
  • Add FileNameRender to compose file name according to the user's request and put filename in starts and events.
  • Add Analayzer to process the data to XRD and PDF and save the processed data in the pyFAI standard and pdfgetx standard file and do calbration if necessary.
  • Add DarkSubtraction to do the dark subtraction of the image in place.
  • Add AnalysisPipeline that contains the Analyzer, DarkSubtraction and Publisher.
  • Add PlotterBase as the basic class of the plotters.
  • Add ImagePlotter to plot the image with or without masks and save image in files.
  • Add WaterfallPlotter to plot the 1d array in a waterfall plot and save the figure in a file at the end.
  • Add ScalarPlotter to plot the scalar array as a function of time or other dimensions and save the figure in a file at the end.
  • Add VisualizationPipeline that contains the ImagePlotter, WaterfallPlotter and ScalarPlotter.
  • Add SerializerBase as the basic class of the serializers.
  • Add TiffSerializer to serialize the images in tiff files.
  • Add CSVSerializer to serialize the scalar data, time stamp and the filename of outputs in csv files.
  • Add YamlSerializer to serialize the start document in a yaml file using the safe_dump.
  • Add NumpySerializer to serialize the masks in npy files.
  • Add SerializationPipeline that contians TiffSerializer, CSVSerializer, YamlSerializer and NumpySerializer.

Changed:

  • Make the callbacks package contain all the callback classes, including the servers.
  • Make the servers able to process the event data from more than one detectors and mutliple different calibrations in one run.
  • Make run_server command start the analysis, serialization and visualization servers separately in three children processes at the same time.
  • Use logging package to stream logs from three processes to sys.stdout.
  • Change the sections and some keys in the configuration so that users can adjust the ANALYSIS section in the configuration using user_config key in the start doc.
  • Cache the calibration data for the integration and the binners for the masking using lru_cache. The cache is valid through the whole session unless it is updated.
  • Change the filename pattern of the output files to avoid duplicated file names from different detector images.
  • Make the time in the output event streams and the time stamps in the file names the sames as the time in the input event streams. The time that users see will be the same as the time that the data is measured instead of the time that the analysis code runs.
  • Allow users to include any measured scalar data in the filename using the user_config keyword.
  • Allow users to tune whether or not to save the figures, save any kind of data, visualize any kind of data, do the pdfgetx processing or do auto masking.
  • Allower users to tune any configuration for auto masking, pyFAI integration and the pdfgetx.

  • Deprecate the old callbacks and servers for the old data structure from the old xpdacq.

Removed:

  • Remove servers package and analyzer package.

v0.5.2

Fixed:

  • The waterfall plot will be auto scaled after each update and delete.

Fixed:

  • The visualization server will clear the plot when the descriptor is received. Before, it clears when the start is received. The plot will remain longer time before the clear.

v0.5.0

Added:

  • Add CalibrationExporter, a callback to export the calibration metadata in poni files.
  • Add xpdvis server and xpdsave server so that the data processing, visualization and exporting can be run in parallel.
  • Add chi_2theta in the outputs.
  • Add yaml metadata output.

Changed:

  • Data emitted from AnalysisStream changes from numpy objects like numpy.ndarray, numpy.float64 to built-in python objects like list, float.
  • Reformat the exported directory structure so that it will be like the outputs from xpdAn.
  • The format of the output files will be the same as those generated by xpdAn.

Fixed:

  • Fixed the bugs encountered at the 28-ID-1 beamline.

v0.4.7

Added:

  • Add AreaDetectorTiffHandler for the xpd and lsq servers.

Changed:

  • The image data can be any array with dimensions N as long as N >= 2. The first N - 2 dimensions will be averaged.
  • Simplify the configuration for the servers.

Deprecated:

  • Deprecate the background subtraction functionality because of the stability.

Fixed:

  • Use v1 databroker interface for the query of dark images info due to the broken xarray conversion in v2 databroker.
  • Fix the bug that server cannot deal with the data for which the background measurement failed.

v0.4.6

Changed:

  • If there is no "calibration_md" in start document, the server will still process the diffraction image but doesn't do the integration and following step. It will use zero for the results depending on the calibration.
  • Move the data processing step to the process_data method in AnalysisStream.

v0.4.5

Added:

  • Allow users to use their own mask by adding the file path in the metadata of the run
