Constant Summary collapse
- SHUCK_METADATA_DIR =
".fakes3_metadataFFF"
- SUBSECOND_PRECISION =
S3 clients with overly strict date parsing fails to parse ISO 8601 dates without any sub second precision (e.g. jets3t v0.7.2), and the examples given in the official AWS S3 documentation specify three (3) decimals for sub second precision.
