- What I did
Add --format output flag to
dump-{object,snapshot,wal}which defaults to"text" (current style) and also accepts "json".
Hopefully this will greatly facilitate future analysis of raft dumps, which are
currently only available as walls of pretty printed protobuf.
- How I did it
Added cobra flag with validation and introduced switch statements to dump path.
- How to test it
dump-{object,snapshot,wal}with--format nope. Confirm this errorsand prints help.
dump-{object,snapshot,wal}without the --format flag, or with--format text. Confirm the output is unchanged from present.dump-{object,snapshot,wal}with--format json. Pipe the output tojqor other json parser and confirm there are no parsing errors. Confirminformation previously presented (e.g. event index from WAL) is still communicated
via the json format.
