stack/erp5: Fix master node separation in NEO URI
Hello Kirill,
in 0cf70a6e we already migrated the NEO URI concatenation to the recent format used by WCFS.
Unfortunately we missed separating the address (IPv6 + port) of the master nodes from each other.
Without adding the separator , between them, WCFS doesn't work with NEO clusters which have multiple master nodes, because NEO/go can't split the different master node addresses.
This is necessary for kirr/neo!2 (merged).
Due to the reasons mentioned in !1308 we can't add automatic tests for this fix now. I therefore created a dedicated instance just to test this fix manually. A bit overkill for such a small fix, but anyway I could verify now that this fix works. If needed I can provide access data for this instance in private.
Best, Levin
