still needs public endpoints recorded here

theta testnet repo needs:

• local test instructions
• public test instructions

where do devnet instructions go?

Posted in slack but adding for visibility. When I try to do a software upgrade using the theta-prepare branch with an exported and modified genesis state, I'm currently getting the following errors:

panic: cannot delete latest saved version (1)

Ok regarding my last message, I've isolated this error to pruning. If I set pruning = "nothing" in my app.toml file, I no longer see any failures.

Testing with or without cosmovisor makes no difference.

Anyone have thoughts about why this could be happening @yaruwangway @okwme?

I have some more data after attempting the upgrade on two local testnets:

1. Using a modified genesis file (from the Hypha testnet repo)
   The upgrade went through OK at block height 9035025, but when it reached 9035030 I got this error:
   Mar 07 20:00:07 dante-local-theta-upgrade cosmovisor[39794]: 8:00PM ERR CONSENSUS FAILURE!!! err="cannot delete latest saved version (6)" module=consensus stack="goroutine 165 [running]:\nruntime/debug.Stack()\n\truntime/debug/stack.go:24 +0x65\ngit.luolix.top/tendermint/tendermint/consensus
   The full log can be found here.

2. Using a "fresh" genesis file
   I only modified the voting parameters in genesis.json to make the upgrade process easier.
   The upgrade went through OK at block height 50 and has gone past 750 now.
   The steps I followed can be found here.

So far, it seems like the pruning fails on an upgrade when we have some non-zero block height.

hi, theta upgrade only has one new module, ica, so i removed ica, then there is no panic at and after upgrade.

[yaruwangway]

i reported in ibc repo cosmos/ibc-go#1088

[dasanchez]

I tested the upgrade on a local testnet again:

• using this commit from theta-prepare
• modified genesis file (block height starts at 9034670)

The upgrade succeeded, and there is no panic 200 blocks later.
I posted the log here.
