Pierre Salagnac created SOLR-17330:
--------------------------------------
Summary: Default value for 'loadOnStartup' is fuzzy
Key: SOLR-17330
URL: https://issues.apache.org/jira/browse/SOLR-17330
Project: Solr
Issue Type: Bug
Security Level: Public (Default Security Level. Issues are Public)
Affects Versions: 9.6
Reporter: Pierre Salagnac
Each core has property {{loadOnStartup}} to decide if the core is opened at
start-up or delayed until first access.
When creating a new core and *not* specifying the property in the request, we
take the default value from {{CoreDescriptor.defaultProperties}} which is
{{true}}.
{code:java|title= defaultProperties}
private static final Map<String, String> defaultProperties = Map.of(....,
CORE_LOADONSTARTUP, "true");
{code}
Then, when we retrieve the value of the property in
{{CoreDescriptor.isLoadOnStartup()}}, if the property is not the core stored
properties, default value is {{false}}.
{code:java|title=isLoadOnStartup()}
String tmp = coreProperties.getProperty(CORE_LOADONSTARTUP, "false");
{code}
Impact is low since all cores are created with value {{"true"}} when not
explicitly created, using value from the default properties. This just makes
the code confusing to read.
