# 🧰 Conduit Toolbox 🦀
Helper tools for [Conduit](https://conduit.rs), a matrix homeserver in rust.
This repository provides binaries to wrangle your conduit homeserver with.
## Tools
### `conduit_sled_to_sqlite`
A one-shot migration tool to convert your sled database to a sqlite one;
Instructions: (read the notes below first)
1. execute `conduit_sled_to_sqlite <database_directory>`
- `conduit_sled_to_sqlite /var/lib/matrix-conduit/conduit_db`
2. the console will be spammed with a bunch of numbers, this is for diagnostic purposes, when the command returns, your database has been converted.
Some notes:
- The conversion process can take a second depending on the speed of the disk of your server, on raspberry pis it could take a while.
- **Have your server turned off** throughout the conversion process, be sure it is updated to a version which uses SQLite as the main database, and only then turn it back on
- If you have the server be on during the conversion process, some data might be missing from the new database
- If you turn the server back on with an older version (which still uses sled), it'll create a brand new sled database in the database directory, which might be confusing.
- The above method places the new database in the same directory as the old one, this'll effectively duplicate your database, if you're sure your server is up-to-date and works with the new database, you can remove the old sled database files under that directory (be sure you have a backup first!);
- `blobs/`
- `db`
- `conf`
- The new database can be anywhere from 2 to 4 times bigger than the old database, if you want to know how much your current database size is, run the following command;
- `du --apparent-size --max-depth=0 -h <database_directory>`
- And if you want to know how much room you have on your disk, you can run this;
- `df -h <database_directory>/` (with that trailing slash)
- Make sure you have this disk-space *extra* on your machine, else the conversion process will fill it up.
## Installing
For the best experience, compile this toolbox locally on your server;
1. Download and install rust, see [rustup](https://rustup.rs/) for more.
2. Be sure that the rust executables are on your `$PATH`
3. You may want to have a compiler and build tools installed on your system, or else cargo will complain about not being able to "link" or "compile" with `cc`.
- on debian/ubuntu-based systems you can install this with `sudo apt install build-essential`
5. `cargo install --locked --git https://github.com/shadowjonathan/conduit_toolbox`\
