Incident Dossier

Zero-value entries-read argument omitted from XGROUP tokens

A caller passes the ENTRIESREAD option set to 0 to XGROUP CREATE or XGROUP SETID. The argument builder should emit the ENTRIESREAD keyword and a '0' token. Instead, when the option value is exactly 0, the trailing ENTRIESREAD and '0' tokens are missing from the produced array.

Initial failing signalENTRIESREAD 0 drops trailing tokensExpected behavior: For both XGROUP CREATE (key, group, '$') and XGROUP SETID (key, group, '0') called with { ENTRIESREAD: 0 }, the returned token array ends with 'ENTRIESREAD', '0'. · actual behavior: For both commands, when called with { ENTRIESREAD: 0 }, the returned token array omits the trailing 'ENTRIESREAD', '0' pair.
