Ganache-cli: How --db option is working ?

Created on 3 May 2017 · 14Comments · Source: trufflesuite/ganache-cli

I wanted to know if there is a database (or a file) where I can have all the informations, transaction etc. that happen on my testrpc. I thought using the option --db but it didn't work in my case. I tried with different formating like testrpc --db="path/to/the/directory", without the "", without the equal sign...
How does it works ? Is there another solution ? I didn't find anything about where testrpc is storing the ledger/datas.
Thanks in advance for the help!

Without mnemonic, it works for me.

ganache-cli -d --db ganache_db -i 123456

actually, in the version which is being installed right now the --db is not mentioned in the readme.

I think it's just quietly being taken off

@domalak
no, it just was not released yet, actually. And current master README.md is ahead of the one we download.

Problem solved, but not in the best possible way :)

In order to use --db we need to do the next:

npm i ethereumjs-testrpc@beta
testrpc --db=$(pwd)/data/testrpc --account="0xa0d6eabe72fd11a3c7e8bbba48899ab4864c2ca275b12fa917bb13e9386d34de, 1000000000000000000000" \
--account="0x3cf44c4d4252d9d9277f5503dac4e365f56c69cff5d1396da4f156dc115ddcac, 1000000000000000000000" \
--account="0x74bdd757948e186d1bc4461c0781dd9d6706d97d92ecb9f788f0793983a733aa, 1000000000000000000000" \
--account="0xdacb9f4a3dd45dce1a4ba8a1077b8631babf0eecf25c147a54f776418210ce7c, 1000000000000000000000" \
--account="0x327bca8f573280e431323dbbaca36b0431089f8702100c91d836b2eadf30c67d, 1000000000000000000000"

the directory should be created before launching the command

@tcoulter @iurimatias, do we expect the new release happening anytime soon?

Would be nice with a relative path... how would I do this?

Is the --db feature working with 4.0.0? I am deploying contracts and then restarting and it doesn't seem like they are still deployed. Just wanted to confirm since this issue is still open.

has anyone used that feature ever?

aleebek on 30 Aug 2017

I am seeing stuff appear in the database folder upon contract migration.

But nothing appears to be reloaded on restart.

I use Ctrl-C to stop testrpc, then restart it using the -m option to result in the same accounts and keys. However, I find that the database does not appear to be reloaded.

I'm using v4.0.0

All,

To use the --db option, you must also specify the mnemonic and network ID.

I'll be making ganache remember these details in the database in a future release. I'll track that under case #407. As such, please comment there if the workaround of specifying the mnemonic & network id isn't working for you.
