Introduction
This is a script to help you fix your rotki DB if something happened and intervention is required.
You can either use the script (which also required you to install python 3.7 and the script's requirements) or use sqlcipher directly. In either case sqlcipher v4 needs to be installed for your OS.
Using sqlcipher directly
This is the steps to follow to use sqlcipher and fix the db manually.
Get sqlcipher v4
Follow the guide per your OS to get sqlcipher v4: https://rotki.readthedocs.io/en/latest/installation_guide.html#build-from-source
Find your user's database
If you are in windows the directory should be: %LOCALAPPDATA%/rotki/data/USERNAME or ``%APPDATA%/rotki/data/USERNAME`
If you are in OSX the directory should be: ~/Library/Application Support/rotki/data/USERNAME
If you are in Linux the directory should be ~/.local/share/rotki/data/USERNAME
where USERNAME is the name of your rotki user.
In that directory there should be a rotkehlchen.db
Access it
If you have succesfully installed sqlcipher then you can just access the DB with it. So sqlcipher ~/.local/share/rotki/data/USERNAME/rotkehlchen.db for Linux. For other OSes use the path that corresponds to your OS as per the previous section.
This should drop you in a DB prompt looking like this:
SQLite version 3.33.0 2020-08-14 13:23:32 (SQLCipher 4.4.2 community)
Enter ".help" for usage hints.
sqlite>
Unlock it and input commands
First think you do is unlock the DB. The DB is encrypted with your user's password. So what you do is write: PRAGMA key="YOURPASSWORD"; , where YOURPASSWORD is your password and press ENTER.
And now that your DB is unlocked input the following one by one:
DROP TABLE IF EXISTS eth2_deposits; and press ENTER
DELETE from used_query_ranges WHERE name LIKE "eth2_deposits_%"; and press ENTER
INSERT OR REPLACE INTO settings(name, value) VALUES('version', '22'); and press ENTER
Now you are done. This was it. Press Ctrl + D multple times to get out of the prompt and open Rotki. It should now work.
Script Installation and running
IF you want to use the script to fix the DB these are the steps to follow
Get sqlcipher v4
Follow the guide per your OS to get sqlcipher v4: https://rotki.readthedocs.io/en/latest/installation_guide.html#build-from-source
Create a python 3.7 virtual env
Create a python 3.7 venv, again from the same guide: https://rotki.readthedocs.io/en/latest/installation_guide.html#build-from-source
Install requirements
pip install -r requirements.txt
Run the script
python main.py --user YOURUSERNAME --password YOURPASSWORD
If you also have somehow specified a custom location for rotki data then you will need to also set it with an extra argument --data-dir /path/to/your/rotki/data/dir/.
