Remove gaia

[alessio]

Gaia is removed from cosmos-sdk repository.

Few changes were required to make sure no packages depend on gaia subpackages.

CI config is amended accordingly.

Unnecessary targets are removed from Makefile.

Simulations run through a lightweight version of gaia renamed to simapp.

[sabau]

I would love to have the repo with gaia alone before merging

[alessio]

@sabau yes, that is exactly the plan

[alexanderbez]

There are still references to Gaia that I think should be cleared up prior to merging. Namely,

• x/genutil/genesis_state.go
• x/genutil/client/cli/validate_genesis.go
• x/genutil/client/cli/init_test.go
• x/genutil/client/cli/gentx.go
• x/crisis/keeper.go
• client/lcd/root.go
• client/keys/delete.go
• client/context/errors.go
• client/config.go
• .github/ISSUE_TEMPLATE/bug-report.md

• What are we going to do with all the non-spec docs?
• What about test_cover?

We should also remove all usage of gaia from simapp as to not cause any confusion. Call it something else?

Minor things. Will be fixed in an ensuing PR.

What do you mean by non-spec docs? Gaia docs will be moved across the new repo in an ensuing PR.

What about test_cover?

What's wrong with test_cover? It seems to build correctly.

[alexanderbez]

I believe these changes are mostly minimal and should be done in this PR. I can help out with the modules.

[rigelrozanski]

@alexanderbez only gaia references I see now are :

genutil/client/cli/init_test.go
42:	require.NoError(t, cmd.RunE(nil, []string{"gaianode-test"}))
66:	require.NoError(t, cmd.RunE(nil, []string{"gaianode-test"}))
106:	require.NoError(t, initCmd.RunE(nil, []string{"gaianode-test"}))

[alexanderbez]

@alessio I believe I have taken care of everything except the docs and some aspects of the Makefile. With regards to the makefile, I believe a lot of cruft can be removed (eg. LDFLAGS). Can you do a quick pass through and clean it up?

[alexanderbez]

ACK -- pending Makefile cleanup.

Now, I want to build and install gaia, but I do not known which repositories should use, cosmos-sdk or gaia? The Gaia repositories v0.0.0 release can used for production?

[alessio]

v0.0.0 is a tentative tag. gaia's master branch at this very moment hosts gaia's current development trunk. So no, it's definitely not suitable for production environments, instead I'd recommend to build gaia from a cosmos-sdk's repo release tag.
