What's New in LTS 2021.2 / LTS 2021-HF02

Nuxeo Server

Core Storage

Asynchronous Blob Digest Calculation dev admin

Some files are uploaded to Nuxeo using external components as "direct upload" and therefore their content is never seen by Nuxeo, which makes it impossible to synchronously compute their digest and use this digest as the blob key.

Having the blob key be a digest is useful for:

  • deduplication,
  • compliance with customer rules that require keys to be digests.

To fix this, we have introduced a process to asynchronously compute the digest of each new blob (after downloading it) and "renaming" the blob key. This renaming involves to move the blob in the blob provider, and to find all documents that have this blob key (thanks to NXP-29516) to change them to use the new key.

To enable this feature, we added a new property to compute the blob digest asynchronously when Nuxeo doesn't see the blob content at upload time:

nuxeo.core.blobstore.digestAsync=true

 More on JIRA ticket NXP-30044

This new capability is also used to add the new blob key for old blobs.

 More on JIRA ticket NXP-30043

Finally, we improved the performance of the search by blob key.

Allow Logging S3 Downloads dev admin

Additional logs are now produced to specifically track S3 downloads.

It can be enabled by adding to lib/log4j2.xml:

<Logger name="S3_Download" level="debug" />

Elasticsearch

New Parameter to Enable Index Aliases

It is now possible to easily activate the Elasticsearch alias usage using a property:

elasticsearch.manageAlias.enabled=true

Note that when switching an existing instance to use Elasticsearch alias you first have to drop the existing elastic index for the repository (named nuxeo by default) then reindex your repository.

Elasticsearch Passthrough

Elasticsearch passthrough is now configurable with certificates from private certificate authorities.

Packaging / Distribution / Installation

Allow Adding New Templates Without Overriding the Whole nuxeo.templates Property

In the previous versions of Nuxeo Platform, there was no other way than overriding the whole nuxeo.templates property in nuxeo.conf if we wanted to add new templates to be deployed in a given environment: that means we had to know the exact list of templates configured by default and all the installed packages.

You can now use nuxeo.append.templates.* properties in nuxeo.conf. All those properties will be sorted alphabetically (for determinism and reproducibility), and all the values will be added after the ones from the nuxeo.templates property when passing everything to the ConfigurationGenerator.

For instance, we could have:

nuxeo.templates=default
...
nuxeo.append.templates.infra=mongodb,redis,kafka
nuxeo.append.templates.cloud=cloud-cloudfront, cloud-directupload

The effective list will be: default,cloud-cloudfront,cloud-directupload, mongodb,redis,kafka.

This could then be used in our default Nuxeo Helm chart:

...
{​{- if or .Values.mongodb.deploy .Values.tags.mongodb }}
    nuxeo.append.templates.mongo=mongodb
    nuxeo.mongodb.server=mongodb://{​{ .Release.Name }}-mongodb:27017
    nuxeo.mongodb.dbname={​{ .Values.nuxeo.mongodb.dbname }}
{​{- end }}
{​{- if or .Values.postgresql.deploy .Values.tags.postgresql }}
    nuxeo.append.templates.postgres=postgresql
    nuxeo.db.name={​{ .Values.nuxeo.postgresql.dbname }}
    nuxeo.db.user={​{ .Values.nuxeo.postgresql.username }}
    nuxeo.db.password={​{ .Values.nuxeo.postgresql.password }}
    nuxeo.db.host={​{ .Release.Name }}-postgresql
    nuxeo.db.port=5432
{​{- end }}
{​{- if or .Values.redis.deploy .Values.tags.redis }}
    nuxeo.append.templates.redis=redis
{​{- end }}
...

Fix Algorithm to Unpublish a Document

Unpublishing a source document now loads only the published documents. This is improving the flow by avoiding searching all the published documents of the section and loading them into the memory.

Previously, File content was deleted in case of ExifTool failure.

File content is now unchanged after an ExifTool failure.

Allow Configuration of Signature Algorithm for SAML

We can now configure the digest algorithm used for the signature with SAML.

To configure a signature algorithm for SAML, add a SignatureAlgorithm entry to the plugin , for instance:

<parameter name="SignatureAlgorithm">http://www.w3.org/2001/04/xmldsig-more#rsa-sha256</parameter>

The signature algorithms are defined by the various SAML and XML specs, in particular RFC 6931. If an algorithm unknown to the current library has to be used, the following more verbose syntax that includes the explicit JCA/JCE key algorithm specifier (RSA in this example) may be used:

<parameter name="SignatureAlgorithm.RSA">http://www.w3.org/2001/04/xmldsig-more#rsa-sha256</parameter>

In the same way it's possible to define a digest algorithm with the DigestAlgorithm parameter:

<parameter name="DigestAlgorithm">http://www.w3.org/2001/04/xmlenc#sha256</parameter>

Consult the normative documents like W3C XML Encryption for the algorithms.
