Environment
Ubuntu 22.04.5 LTS, x86_64, one-zone loopback observer. The retained logs were mode 0600.
All paths and values in this test were synthetic and local.
Steps to reproduce
Run as root@sys on a disposable cluster:
SET DECRYPTION IDENTIFIED BY 'EDBF_REPORT_RESTORE_PASSWORD';
SET @kms_encrypt_info='EDBF_REPORT_UNUSED_KMS_INFO';
ALTER SYSTEM RESTORE edbf_restore_probe
FROM 'file:///tmp/edbf-missing-backup'
WITH 'kms_encrypt=true&invalid_probe=true'
WITH KEY FROM 'file:///tmp/edbf-missing-key'
ENCRYPTED BY 'EDBF_REPORT_KMS_ENCRYPT_KEY';The nonexistent local paths make the request fail without contacting storage or KMS. Inspect the
new run's rootservice.log; the authoritative raw log is bundled as
artifacts/rootservice.log:
WDIAG [RS.RESTORE] fill_physical_restore_job ... fail to parse restore_option(
arg={tenant_name:"edbf_restore_probe",
passwd_array:"<password-derived stage2 value>",
kms_uri:"file:///tmp/edbf-missing-key",
kms_encrypt_key:"EDBF_REPORT_KMS_ENCRYPT_KEY", ...})The source sink is src/rootserver/restore/ob_restore_util.cpp:51:
LOG_WARN("fail to parse restore_option", K(ret), K(arg), K(job_id));ObPhysicalRestoreTenantArg stringification includes passwd_array_, kms_uri_,
kms_encrypt_key_, and other restore fields. In the authoritative run, retained-log probes found
the password-derived value and synthetic KMS encryption key. The separate kms_info sentinel was
not observed and is not claimed here.
✔️ Expected Behavior
Restore failures should log identifiers, option names, and the error code while redacting password, key, token, and credential fields.
❌ Actual Behavior
The rootservice warning serializes the complete restore argument, including password-derived and KMS encryption-key carriers. The observer remained healthy; this is a diagnostic-data exposure, not a crash or proof that the key was used successfully.
