CHAP.saxswaxs.server package

Daemon-like application for efficient automated SAXS/WAXS data processing.

Submodules

CHAP.saxswaxs.server.chap module

CHAP.saxswaxs.server.logging_config module

Logging configuration

class StreamToLogFile(handler)

Bases: object

Write stdout/stderr directly to the rotating log file.

property encoding

flush()

isatty()

write(message)

get_logger(name='CHAP.saxswaxs.server.logging_config', log_level='DEBUG')

get_task_logger(name, log_level='DEBUG')

Return a logger that writes only to the active task log file.

Unlike get_logger(), the returned logger is not attached to the shared application log handler. If no task context is active the logger has no handlers and its output is silently discarded.

set_logdir(path)

task_log_context(log_path)

Context manager that tees log output to a per-task append-only file.

While active, all loggers created via get_logger() write to log_path in addition to the shared rotating log file, using the same formatter. Raw stdout/stderr writes are also teed to the same file without any additional formatting. The file is always opened in append mode so successive calls accumulate rather than overwrite.

CHAP.saxswaxs.server.saxswaxs_to_chap module

Script to act as a drop-in replacement for the old saxswaxsworkflow CLI tool. Instead of running the old workflow code, a new CHAP pipeline will be constructed & run from the given tool & map configs.

class VerboseSafeDumper(stream, default_style=None, default_flow_style=False, canonical=None, indent=None, width=None, allow_unicode=None, line_break=None, encoding=None, explicit_start=None, explicit_end=None, version=None, tags=None, sort_keys=True)

Bases: SafeDumper

YAML SafeDumper subclass that writes all nodes explicitly without aliases.

ignore_aliases(data)

Return True to prevent YAML from using anchor/alias references.

convert_configs(outputdir, tool_config_files, detector_filename='detector_config.yaml', pyfai_filename='pyfai_integration_processor_config.yaml', correction_filename='corrections_config.yaml', fits_filename='fits_config.yaml')

Write the new CHAP.saxswaxs-formatted pyfai and corrections config files based on the old workflow tool files provided. Should be independent from any map configuration or saxswaxsworkflow.workflow.Workflow object – use the dictionaries in the tool_config_files only.

make_pipeline(outputdir, map_filename='map_config.yaml', detector_filename='detector_config.yaml', pyfai_filename='pyfai_integration_processor_config.yaml', correction_filename='corrections_config.yaml', fits_filename='fits_config.yaml', pipeline_filename='pipeline.yaml')

Compose a pipeline file for a complete saxswaxs workflow based on the config files provided, and asssuming they all already exist. Sort of a lightweight version of wf_to_chap.

saxswaxs_to_chap(map_config_file, tool_config_files, outputdir, detector_filename='detector_config.yaml', pyfai_filename='pyfai_integration_processor_config.yaml', correction_filename='corrections_config.yaml', fits_filename='fits_config.yaml', pipeline_filename='pipeline.yaml')

Build CHAP pipeline config files from old-style saxswaxs workflow configs.

Converts old-style tool config files to CHAP-format detector, pyFAI integration, and corrections config files via convert_configs(), then composes the CHAP pipeline config YAML via make_pipeline().

Parameters:

• map_config_file (str) – Path to the map config YAML file.

• tool_config_files (list[str]) – List of tool config YAML file paths.

• outputdir (str) – Directory in which to write the output CHAP config files.

• detector_filename (str, optional) – Output filename for the detector config YAML, defaults to 'detector_config.yaml'.

• pyfai_filename (str, optional) – Output filename for the pyFAI integration processor config YAML, defaults to 'pyfai_integration_processor_config.yaml'.

• correction_filename (str, optional) – Output filename for the corrections config YAML, defaults to 'corrections_config.yaml'.

• fits_filename (str, optional) – Output filename for the fits config YAML, defaults to 'fits_config.yaml'.

• pipeline_filename (str, optional) – Output filename for the CHAP pipeline config YAML, defaults to 'pipeline.yaml'.
