class swh.objstorage.backends.in_memory.InMemoryObjStorage(**kwargs)[source]#

Bases: ObjStorage

In-Memory objstorage.

Intended for test purposes.

PRIMARY_HASH: LiteralPrimaryHash = 'sha1'#
name: str = 'memory'#

Default objstorage name; can be overloaded at instantiation time giving a ‘name’ argument to the constructor

check_config(*, check_write)[source]#

Check whether the object storage is properly configured.

Parameters:

  • check_write (bool) – if True, check if writes to the object storage

  • succeed. (can)

Returns:

True if the configuration check worked, False if ‘check_write’ is True and the object storage is actually read only, and an exception if the check failed.

add(content: bytes, obj_id: ObjId, check_presence: bool = True) → None[source]#

Add a new object to the object storage.

Parameters:

  • content – object’s raw content to add in storage.

  • obj_id – either dict of checksums, or single checksum of [bytes] using [ID_HASH_ALGO] algorithm. It is trusted to match the bytes.

  • check_presence (bool) – indicate if the presence of the content should be verified before adding the file.

Returns:

the id (bytes) of the object into the storage.

get(obj_id: ObjId) → bytes[source]#

Retrieve the content of a given object.

Parameters:

obj_id – object id.

Returns:

the content of the requested object as bytes.

Raises:

ObjNotFoundError – if the requested object is missing.

delete(obj_id: ObjId)[source]#

Delete an object.

Parameters:

obj_id – object identifier.

Raises:

ObjNotFoundError – if the requested object is missing.
