In BaseX 10:
In an updating function I have a call to another updating function that uses update:output() to log messages.
If that function call is included, BaseX says that expressions must be all updating, but if I remove the call, BaseX is happy.
The calling function is:
declare %updating%rest:path('/now/rest/analytics/store-latest-acrolinx-users' )
function now:storeAcrolinxUsers() {
let $acrolinxMap as map(*)? :=
try {
acrolinx:getUserDataMap()
} catch * {
util:logToConsole(
'storeAcrolinxUsers'
,``[`{$err:code}` - `{$err:description}`]``
,'warn'
)
}
return
if (exists($acrolinxMap))
then
let $doc as element() := acrolinx:serializeAcrolinxUserMap($acrolinxMap)
let $fileName as xs:string := 'acrolinx-users_' || replace($doc/@timestamp, ':', '~') || '.xml'
return db:put(analyticsmgmt:getAnalyticsDatabase(), $doc, relpath:newFile('acrolinx/users', $fileName))
};
The offending function is util:logToConsole(), which is declared as:
declare %updating function util:logToConsole($functionName as xs:string,
$message as xs:string,
$logLevel as xs:string
) {
let $logMessage as xs:string := '[' || upper-case($logLevel) || '] ' || $functionName || '(): ' || $message
return
(
update:output(prof:dump($logMessage)) ,
update:output($logMessage)
)
};
This is declared as an updating function and returns “updating” functions.
If I comment out the call to util:logToConsole() in the first function, then BaseX is happy.
If I use the non-updating version of logToConsole(), util:logToLog(), then BaseX is also happy.
So my question is: why is BaseX complaining about the use of this updating function in an updating function?
There must be some subtlety that I’m missing but I have not yet figured out what it is.
Thanks,
Eliot
