Hyperledger fabric switching from levelDB to couchDB

Asked 2020-Dec-20 at 11:47

I have a problem switching from levelDB to couchDB as the state database. I'm using the test-network from the hyperledger sample repository and I have edited the docker-compose-couch.yaml file inside of the docker folder and the core.yaml file inside of the config folder.
These are all the changes that I made, but when I start the network it still uses leveldb.
Starting nodes with CLI timeout of '5' tries and CLI delay of '3' seconds and using database 'leveldb'

core.yaml:

QUESTION

How to test db errors in go?

Asked 2019-Jul-06 at 07:52

I am implementing a storer that is backed by leveldb (https://github.com/syndtr/goleveldb) in go. I am new to go and am trying to figure out how I get test coverage for the condition in the code below where perr != nil. I can test my own errors ok, but I can't figure out how to reliably get the Put method of leveldb to return an error. Mocking out a db just to get test coverage up for a few edge cases seems like a lot of work for not much reward. Is mocking leveldb my only real choice here? If so what's the recommended mocking framework for go? If there's another way what is it?

Mocking is the general chosen approach for this kind of test, which is why golang/mock, for instance, has a mockgen command, to generate the test code.

mockgen has two modes of operation: source and reflect.

Source mode generates mock interfaces from a source file.
It is enabled by using the -source flag.
Other flags that may be useful in this mode are -imports and -aux_files.

LevelDB is a log-structured merge-tree and has transaction logs (the ones you were inspecting with hexdump). With this code you can validate that only one value is present for your key:
