Arvados

The Python SDK should provide arvados.collection.Manifest and arvados.collection.ManifestRecord classes for processing collection manifests.

All Python code that builds or parses a collection manifest should use these classes.

• arvados.collection.ManifestRecord
  • A constructor that parses a string into a ManifestRecord
  • ManifestRecord.stream - the stream name supplied in this record
  • ManifestRecord.blocks - a list of the blocks specified in this record
  • ManifestRecord.files - a list of the files specified in this record
  • ManifestRecord.str() - returns the record serialized into a string (no newline)
    • The output of ManifestRecord(foo).str() should be guaranteed to be identical to foo (with the exception that whitespace is normalized to one space between words)
• arvados.collection.Manifest
  • A constructor that produces a Manifest class from a raw string (i.e. the manifest_text in the database).
  • Manifest.records() an iterator that returns each ManifestRecord in this manifest in turn
  • Manifest.str() returns the full manifest as a string
    • The output of Manifest(foo).str() is guaranteed to be identical to foo (with the exception that whitespace is normalized to one space between words)
