Inconsistent Webserver Validation Results

[austinmatherne-wk]

Hi @freddym56,

We received a support email regarding inconsistent EDGAR validation results from the webserver. The issue is that mappedPaths is reset on each request, so the __xule_resources_dir__ mapping registered once in init() is lost after the first request. This can be avoided by moving the registration outside the once-only guard so it re-registers on every call, with a duplicate check for idempotency.

The issue can be replicated by running:

# start server
python arelleCmdLine.py --webserver localhost:8080 &

# first request returns validation results
curl 'localhost:8080/rest/xbrl/validation' \
    --get \
    --output first-request.json \
    --data-urlencode 'file=https://www.sec.gov/Archives/edgar/data/1445305/000144530525000142/0001445305-25-000142-xbrl.zip' \
    --data-urlencode 'media=json' \
    --data-urlencode 'plugins=EDGAR|xule' \
    --data-urlencode 'disclosureSystem=efm-pragmatic'

# second request triggers: xule:ValidationException - No such file or directory: '/__xule_resources_dir__/dqcrt-us-2025-ruleset.zip'
curl 'localhost:8080/rest/xbrl/validation' \
    --get \
    --output second-request.json \
    --data-urlencode 'file=https://www.sec.gov/Archives/edgar/data/1445305/000144530525000142/0001445305-25-000142-xbrl.zip' \
    --data-urlencode 'media=json' \
    --data-urlencode 'plugins=EDGAR|xule' \
    --data-urlencode 'disclosureSystem=efm-pragmatic'

first-request.json
second-request.json

We couldn't include this change in the final version of release 26.1 but we will add to a future release.
