I found the proximate cause: Not having UPDINDEX set to true() on the failing
server.
When I set UPDINDEX to true on the target database, then the load succeeded.
Tracking through the Java code it looks like a failure to initialize the idmap
member of the DiskData object. This code looks like it could be the issue:
// open data and indexes
init();
if(meta.updindex) {
idmap = new IdPreMap(meta.dbFile(DATAIDP));
if(meta.textindex) textIndex = new UpdatableDiskValues(this, IndexType.TEXT);
if(meta.attrindex) attrIndex = new UpdatableDiskValues(this,
IndexType.ATTRIBUTE);
if(meta.tokenindex) tokenIndex = new UpdatableDiskValues(this,
IndexType.TOKEN);
} else {
if(meta.textindex) textIndex = new DiskValues(this, IndexType.TEXT);
if(meta.attrindex) attrIndex = new DiskValues(this, IndexType.ATTRIBUTE);
if(meta.tokenindex) tokenIndex = new DiskValues(this, IndexType.TOKEN);
}
if(meta.ftindex) ftIndex = new FTIndex(this);
The idmap is only set of meta.updIndex is true.
Cheers,
E.

Subject: Consistent NPE loading content on one server, other server works
I have two servers running the same code, both on 10.7. I have a REST API
handler that takes data as input and stores it in a database, applying some
preprocessing to the data first.
The data successfully loads on my dev server and consistently fails on the
production server, with this Java failure:
[INFO] Posting
"/Users/eliot.kimber/git-basex/product-content-analytics/analytics/adobe/adobe-analytics-Utah_Pages_Viewed_Aug2023-clean.csv"
[INFO] as filename "adobe-analytics-Utah_Pages_Viewed_Aug2023-clean.csv"
[INFO] to Mirabel server "http://mirabel.corp.service-now.com:9984";...
Unexpected error: Improper use? Potential bug? Your feedback is welcome:

The two servers are essentially identical Linux servers, although the
production server has more resources.
Any idea what might cause this failure or what I can do to diagnose it?
There must be some non-obvious difference in these two servers but I don’t know
what to look for.
The code doing the load to a database is:
let $reportPath as xs:string :=
``[/`{$analyticsmgmt:csvPathRoot}`/`{$source}`/`{$reportType}`/`{$reportName}`.xml]``
let $msg := prof:dump(``[[INFO] Storing analytics report
"`{$reportPath}`"]``)
let $csv := $csv transform with { insert node attribute {'timestamp'}
{$timeStampStr} into ./* }
let $csv := $csv transform with {
analyticsmgmt:dispatchAnalysticsStorePreProcessing($reportName, ., $debug) }
return
try {
(db:put($analyticsDb, $csv, $reportPath),
db:optimize($analyticsDb,
true(),
map{
'attrindex' : true(),
'tokenindex' : true(),
'updindex' : true()
})
)
} catch * {
util:logToConsole(
'analyticsmgmt:storeAnalyticsCsvReport',
``[`{$err:code}`: `{$err:description}`]``,
'error'
)
}
Thanks,
Eliot
