smarti-0.6.1
4f0c4b1

Smarti 0.6.1 is a security feature release, that also covers several improvements to optimize Smarti’s resource consumption behavior. This is the first Smarti release, that has a Docker image as part of its distribution.

Smarti 0.6.1 is 100% compatible to chatpal-search - A Rocket.Chat package for search with chatpal backend. So Smarti can be used as cross-channel search engine for Rocket.Chat.

New in Smarti 0.6.1

From the feature perspective Smarti 0.6.1 introduces a simple user management including form based user authentication as well as token based system authentication. Users having the role ADMIN are allowed to manage clients, configurations, conversations, users and tokens. Regular Smarti users are only permitted to manage configurations and conversations of specific clients. Tokens are designed to access the Smarti API by technical systems/users.

The Smarti Admin UI allows you to:

  • manage (create, change and delete) users,
  • permit users access to specific clients,
  • generate tokens to allow technical access,

Upgrading

Stanford-NLP

For improved memory efficiency, smarti now uses Stanford-CoreNLP v3.8.0. If you added the Stanford-NLP dependencies in previous versions, you must update those libraries. Please refer to the Installation Guide for details.

Configuration

The following changes in the configuration files are recommended:

application.properties

+ nlp.stanfordnlp.de.parseModel=edu/stanford/nlp/models/srparser/germanSR.ser.gz
+ nlp.stanfordnlp.de.parseMaxlen=40

- security.password=
+ security.config.mongo.admin-password=

+ smarti.migration.mongo.script-home=/usr/share/smarti/scripts

logback.xml

- <logger name="io.redlink.nlp" level="DEBUG"/>
+ <logger name="edu.stanford" level="INFO"/>
+ <logger name="io.redlink.nlp" level="INFO"/>

Client-Configuration
Previous client-configurations for solrsearch-query-builders might require an update of their default settings: While in previous versions those parameters needed to be url-encoded, this is now happening within the component.

A migration-script is available and applied automatically on starup:

function runDatabaseMigration() {
    var clientConfig = db.getCollection('configuration');

    clientConfig
        .find({'config.queryBuilder': { $elemMatch: { type: 'solrsearch' }}})
        .forEach(function (configuration) {
            configuration.config.queryBuilder.forEach(function (builder) {
                if (builder.type !== 'solrsearch') return;

                var convertedDefaults = {};
                for (var k in builder.defaults) {
                    if (builder.defaults.hasOwnProperty(k)){
                        try {
                            convertedDefaults[k] = decodeURIComponent(builder.defaults[k]);
                        } catch (e) {
                            print('Could not uri-decode "' + k + "' of config '" + builder.name + "' for client '" + configuration.client + "'." +
                                " Keeping unmodified parameter '" + builder.defaults[k] + "'");
                            convertedDefaults[k] = builder.defaults[k];
                        }
                    }
                }
                builder.defaults = convertedDefaults;
            });

            clientConfig.save(configuration);
        });
}
