Change & Version Information¶
The following is a summary of changes and improvements to
eulfedora
. New features in each version should be listed, with
any necessary information about installation or upgrade notes.
0.23¶
- Related objects accessed via
Relation
are now cached for efficiency, similar to the way datastreams are cached onDigitalObject
. - Methods
purge_relationship()
andmodify_relationship()
added toDigitalObject
. Contributed by Graham Hukill @ghukill.
0.22.2¶
- bugfix: correction in detailed output for validate-checksum script when all versions are checked and at least one checksum is invalid
0.22.1¶
- bugfix: support HTTP Range requests in
eulfedora.views.raw_datastream()
only when explicitly enabled
0.22¶
- A repository administrator can configure a script to periodically check content checksums in order to identify integrity issues so that they can be dealt with.
- A repository administrator will receive an email notification if the system encounters bad or missing checksums so that they can then resolve any integrity issues.
- A repository admin can view fixity check results for individual objects in the premis data stream (for objects where premis exists) in order to view a more detailed result and the history.
- Support for basic HTTP Range requests in
eulfedora.views.raw_datastream()
(e.g., to allow audio/video seek in HTML5 media players)
0.21¶
- It is now possible to add new datastreams using
eulfedora.models.DigitalObject.getDatastreamObject()
(in contrast to predefined datastreams on a subclass ofDigitalObject
). Adding new datastreams is supported when ingesting a new object as well as when saving an existing object. This method can also be used to update existing datastreams that are not predefined on a DigitalObject subclass.
0.20¶
- Development requirements can now be installed as an optional requirement
of the eulfedora package (
pip install "eulfedora[dev]"
). - Unit tests have been updated to use
nose
- Provides a nose plugin to set up and tear down for a test Fedora Commons repository instance for tests, as an alternative to the custom test runners.
0.19.2¶
- Bugfix: don’t auto-create an XML datastream at ingest when the xml content
is empty (i.e., content consists of bootstrapped
xmlmap.XmlObject
only)
0.19.1¶
- Bugfix: handle Fedora restriction of ownerId field length to 64 characters.
When setting
owner
, will now warn and truncate the value to allow the object to be saved.
0.19.0¶
- New command-line script
fedora-checksums
for datastream checksums validation and repair. See Scripts for more details. DigitalObject
now provides access to the Fedora built-in audit trail; seeaudit_trail
. Also provides:eulfedora.views.raw_audit_trail()
: Django view to serve out audit trail XML, comparable toeulfedora.views.raw_datastream()
.DigitalObject
attributeaudit_trail_users
: set of all usernames listed in the audit trail (i.e., any users who have modified the object)DigitalObject
attributeingest_user
: username responsible for ingesting the object into Fedora if ingest is listed in the audit trail
Relation
now supports recursive relations via the optiontype="self"
.- API wrappers have been updated to take advantage of all methods
available in the REST API as of Fedora 3.4 which were unavailable in
3.2. This removes the need for any SOAP-based APIs and the
dependency on
soaplib
. - Minor API / unit test updates to support Fedora 3.5 in addition to 3.4.x.
0.18.1¶
- Bugfix: Default checksum type for
DatastreamObject
was previously ignored when creating a new datastream from scratch (e.g., when ingesting a new object). In certain versions of Fedora, this could result in datastreams with missing checksums (checksum type of ‘DISABLED’, checksum value of ‘none’).
0.18.0¶
- Exposed RIsearch
count
return option viaeulfedora.api.ResourceIndex.count_statements()
DatastreamObject
now supports setting datastream content by URI through the newds_location
attribute (this is in addition to the previously-availablecontent
attribute).
0.17.0¶
Previously, several of the REST API calls in
eulfedora.api.REST_API
suppressed errors and only returned True or False for success or failure; this made it difficult to determine what went wrong when an API call fails. This version ofeulfedora
revises that logic so that all methods ineulfedora.api.REST_API
will raise exceptions when an exception-worthy error occurs (e.g., permission denied, object not found, etc. - anything that returns a 40x or 500 HTTP error response from Fedora). The affected REST methods are:addDatastream()
modifyDatastream()
purgeDatastream()
modifyObject()
purgeObject()
setDatastreamState()
setDatastreamVersionable()
New custom Exception
eulfedora.util.ChecksumMismatch
, which is a subclass ofeulfedora.util.RequestFailed
. This exception will be raised ifaddDatastream()
ormodifyDatastream()
is called with a checksum value that Fedora determines to be invalid.Note
If
addDatastream()
is called with a checksum value but no checksum type, current versions of Fedora ignore the checksum value entirely; in particular, an invalid checksum with no type does not result in aChecksumMismatch
exception being raised. You should see a warning if your code attempts to do this.Added read-only access to
DigitalObject
owners as a list; changed defaulteulfedora.models.DigitalObject.index_data()
to make owner field a list.Modified default
eulfedora.models.DigitalObject.index_data()
and sample Solr schema to include a new field (dsids) with a list of datastream IDs available on the indexed object.
0.16.0 - Indexing Support¶
- Addition of
eulfedora.indexdata
to act as a generic webservice that can be used for the creation and updating of indexes such as SOLR; intended to be used witheulindexer
.
0.15.0 - Initial Release¶
- Split out fedora-specific components from
eulcore
; now depends oneulxml
.
