this is a poor / partial / non-compliant dat implementation in rust.
it will eat-your-data!
- [ ] SLEEP v2 files and registers
- [x] read/write file headers
- [x] read/write file chunks as raw bytes
- [x] pread/pwrite file chunks without seeking
- [x] read data entries by index
- [x] append data entries
- [x] verify entire register (signatures and merkel tree)
- [ ] receive and insert data out of order
- [ ] bitfields
- [ ] Drive metadata and files
- [x] read full history ("log")
- [x] read file tree ("ls")
- [x] import file to register
- [x] export file from register
- [x] import/export directories recursively
- [ ] Protocol
- [x] send/receive encrypted messages to a known host
- [ ] bitfields
- [ ] Discovery
- [x] centralized DNS
- [ ] mDNS (local DNS)
- [ ] DHT (distributed hash table)
- [ ] Peer Synchronization
- [ ] receive entire register from a known host
- [ ] share (upload) register to a known host
- [ ] Wrapper commands
- [ ] clone
- [ ] share
- [x] log
- [ ] status
- [ ] add
Significant simplifications were made compared to the regular dat client:
- Content data is always stored in the SLEEP directory (
content.data), instead of just having the latest data in files in the working directory. This results in data duplication.
- Sparse registers aren't implemented: full history needs to be present for both metadata and content.
- Tracking of remote node state (bitfields) is minimized as much as possible.
- Almost everything is synchronous and single-threaded, so only a single remote node connection at a time is allowed.
Notable Rust Libraries:
rust-crypto for hashing (BLAKE2b)
sodiumoxide signing (Ed25519) and network stream encryption (XSalsa20)
integer-encoding for simple "varints"
rust-protobuf for protobuf messages
Requires the libsodium library installed system-wide to run, and header files
libsodium-dev) for now, due to dynamic linking and the simple build
configuration. It should be possible to statically link a free-standing
executable, and to auto-build the libsodium C library during compilation if it
isn't found system-wide.
protobuf encode/decode methods are auto-generated ahead of time using
rust-protobuf, so if you're just compiling or installing
geniza you don't
need any special tools. However, if you change or extend the
files, you do, along with the
protoc tool (
sudo apt install
protobuf-compiler) and rust plugin
protobuf). The command to regenerate a single file is:
protoc --rust_out . network_msgs.proto
