Olaoluwa Osuntokun 56a7f45b99 graphdb: fix backwards-compat for channel edge feature deserialization ... This commit fixes a backwards compatibility issue that prevented nodes from upgrading from v0.19.x to v0.20.x. In v0.19.x, channel edge features were serialized as raw feature bytes without a length prefix. In v0.20.x (commit 2f2845dfc), the serialization changed to use Features.Encode() which adds a 2-byte big-endian length prefix before the feature bits. The deserialization code was updated to use Features.Decode() which expects this length prefix. When v0.20.x reads a database created by v0.19.x, Decode() tries to read a length prefix that doesn't exist, causing an EOF error: unable to decode features: EOF The fix adds a deserializeChanEdgeFeatures() helper that detects which format is being read and decodes accordingly: - New format (v0.20+): First 2 bytes encode the length of the remaining bytes. Detected when uint16(bytes[0:2]) == len(bytes)-2. - Legacy format (pre-v0.20): Raw feature bits without length prefix. Uses DecodeBase256 with the known length. The format detection is safe because in the legacy format, the first byte always has at least one bit set (the serialization uses minimum bytes), so the first two bytes can never encode a value equal to len-2. Fixes #10528.		2026-02-03 09:12:04 -08:00
