openquake.engine package


openquake.engine.engine module

Engine: A collection of fundamental functions for initializing and running calculations.

exception openquake.engine.engine.MasterKilled[source]

Bases: exceptions.KeyboardInterrupt

Exception raised when a job is killed manually


Build a correspondence between the outputs in the datastore and the ones in the database.

Parameters:dstore – datastore
openquake.engine.engine.job_from_file(cfg_file, username, hazard_calculation_id=None)[source]

Create a full job profile from a job config file.

  • cfg_file (str) – Path to a job.ini file.
  • username (str) – The user who will own this job profile and all results
  • datadir (str) – Data directory of the user
  • hazard_calculation_id – ID of a previous calculation or None

a pair (job_id, oqparam)

openquake.engine.engine.raiseMasterKilled(signum, _stack)[source]

When a SIGTERM is received, raise the MasterKilled exception with an appropriate error message.

  • signum (int) – the number of the received signal
  • _stack – the current frame object, ignored
openquake.engine.engine.run_calc(job_id, oqparam, log_level, log_file, exports, hazard_calculation_id=None)[source]

Run a calculation.

  • job_id – ID of the current job
  • oqparamopenquake.commonlib.oqvalidation.OqParam instance
  • log_level (str) – The desired logging level. Valid choices are ‘debug’, ‘info’, ‘progress’, ‘warn’, ‘error’, and ‘critical’.
  • log_file (str) – Complete path (including file name) to file where logs will be written. If None, logging will just be printed to standard output.
  • exports – A comma-separated string of export types.

openquake.engine.logs module

Set up some system-wide loggers

class openquake.engine.logs.LogDatabaseHandler(job_id)[source]

Bases: logging.Handler

Log stream handler

class openquake.engine.logs.LogFileHandler(job_id, log_file)[source]

Bases: logging.FileHandler

Log file handler

class openquake.engine.logs.LogStreamHandler(job_id)[source]

Bases: logging.StreamHandler

Log stream handler

openquake.engine.logs.dbcmd(action, *args)[source]

A dispatcher to the database server.

  • action – database action to perform
  • args – arguments
openquake.engine.logs.handle(*args, **kwds)[source]

Context manager adding and removing log handlers.

  • job_id – ID of the current job
  • log_level – one of debug, info, warn, error, critical
  • log_file – log file path (if None, logs on stdout only)

Initialize logs to write records with level level or above.


If a log file destination is specified, attempt to open the file in ‘append’ mode (‘a’). If the specified file is not writable, an IOError will be raised.
