There is an issue in ExtractNamespaceFromPredicate. The issue is the parsing was done assuming ns in <ns>-<attr> to be decimal (actually it is hexadecimal). This leads to the following issues.

  • A predicate a-name, it was skipped.
  • A predicate 11-name was parsed as namespace 11, actually it is namespace 17 (0x11).

This change is Reviewable

We used to store predicate as <namespace>|<attribute> (pipe | signifies concatenation). We store this as a string. <namespace> is 8 bytes uint64, which when marshaled to JSON bytes mess up the predicate. This is because for the namespace greater than 127, the UTF-8 encoding might take up several bytes (also if the mapping does not exist, then it replaces it with some other rune). This affects three identified places in Dgraph:

Live loader
Backup and List Backup
Http clients and Ratel
Fix:
Fix is to have a UTF-8 string when dealing with JSON. A better idea is to use UTF-8 string even for internal operations. Only when we read/write to badger we convert it into the format of the byte.
New Format: <anmespace>-<attribute> (- is the hyphen literal)

fix(restore): update the schema and type from 2103 (#7838)

With #7810 change, we changed the format of the predicate. We missed updating the schema and predicate. This PR fixes it.

fix(backup): handle manifest version logic, update manifest version to 2105 (#7825)

The backward compatibility of the backup's manifest was broken by #7810, although the tool was added (#7815) that enables smooth migration of manifest.
This PR makes backup backward compatible, by updating the manifest(in-memory) after reading.

fix(updatemanifest): update the version of manifest after update (#7828)

We were not updating the manifest version after the updation. This PR fixes that.
