When failed credential store flush to file on the disk then we have inconsistency between credential store in memory and persisted file. ---------------------------------------------------------------------------------------------------------------------------------------- Key: ELY-1042 URL: https://issues.jboss.org/browse/ELY-1042 Project: WildFly Elytron Issue Type: Bug Components: Credential Store Reporter: Hynek Švábek Assignee: Darran Lofthouse Priority: Critical When failed credential store flush to file on the disk then we have inconsistency between credential store in memory and persisted file. I expect consistent state, same aliases in memory and persisted on disk. We must not add new aliases only to memory. This problem is exported from issue https://issues.jboss.org/browse/JBEAP-6866 where is noted as secondary problem. *HOW TO REPRODUCE* {code} /subsystem=elytron/credential-store=cs001:add(uri="cr-store://test/cs/credentialstore.jceks?create=true", credential-reference={clear-text=pass123}, relative-to="jboss.server.data.dir") {code} {code} /subsystem=elytron/credential-store=cs001/alias=alias001:add(secret-value=secretvalue) {code} Now is credentialstore.jceks file persisted on disk here *JBOSS_HOME/standalone/data/cs* Please remove write permission for folder "cs" {code} chmod g-w cs chmod u-w cs {code} Try add another entry to credential store /subsystem=elytron/credential-store=cs001/alias=alias002:add(secret-value=secretvalue) { "outcome" => "failed", "failure-description" => "WFLYELY00009: Unable to complete operation. 'ELY09525: Unable to flush credential store to storage'", "rolled-back" => true } And you get error message as above. Now you list all aliases in credential store: {code} /subsystem=elytron/credential-store=cs001:read-children-names(child-type=alias) { "outcome" => "success", "result" => [ "alias001", "alias002" ] } {code} There is non persisted "alias002" too. *Now we check aliases in persisted file:* {code} reload {code} There isn't any alias "alias002" after reload. {code} /subsystem=elytron/credential-store=cs001:read-children-names(child-type=alias) { "outcome" => "success", "result" => ["alias001"] } {code}
