Serge Huber created UNOMI-399:
---------------------------------
Summary: Default allow-list for expression filter not properly
loaded from config
Key: UNOMI-399
URL: https://issues.apache.org/jira/browse/UNOMI-399
Project: Apache Unomi
Issue Type: Bug
Components: core
Affects Versions: 1.5.2, 1.5.3
Reporter: Serge Huber
Fix For: 1.5.4
In custom.system.properties we can customize the list of allowed expression as
in the following example:
{code}
org.apache.unomi.scripting.filter.mvel.allow=${env:UNOMI_SCRIPTING_FILTER_MVEL_ALLOW:-\
\\Q'systemProperties.campaigns.'+campaignId+'Engaged'\\E,\
\\Q'properties.pageViewCount.' + (scope != null ? scope :
'defaultSiteKey')\\E,\
\\Q'properties.interests.'+ (interestName != null ?
interestName.toLowerCase() : 'default')\\E,\
\\Qevent.properties['src_languages.values'] != null ?
event.properties['src_languages.values'].toLowerCase() : 'en'\\E,\
\\Qevent.properties['src_terms[0].term'] != null ?
event.properties['src_terms[0].term'].toLowerCase() : ''\\E,\
\\Qr = profile.properties['interests']; foreach(interest :
event.target.properties['interests'].entrySet()) { if (r == null) { r =
[interest.key: interest.value] } else if (r[interest.key] != null) {
r[interest.key] = r[interest.key] + interest.value } else { r[interest.key] =
interest.value } } r\\E,\
\\Qr = profile.properties['pageViewCount']; if (r == null) {
profile.properties['pageViewCount'] = []; profile.properties.pageViewCount =
[event.scope : 1] } else { if (r[event.scope] != null) { r[event.scope] =
r[event.scope] + 1 } else { r[event.scope] = 1 }} r\\E,\
\\Qevent.properties['src_terms[0].term'].toLowerCase()\\E}
{code}
Unfortunately due to a bug in the loading code this list is not properly
loaded.
However JSON files coming from bundles are properly managed so as a workaround
a bundle can be used to populate the list.
Also there is a bug in the ScriptExecutor for MVEL that returns the script
instead of NULL when the script is filtered out.
