List of forked dependencies During conduwuit development, we have had to fork

some dependencies to support our use-cases in some areas. This ranges from things said upstream project won't accept for any reason, faster-paced development (unresponsive or slow upstream), conduwuit-specific usecases, or lack of time to upstream some things.

• ruma/ruma: https://github.com/girlbossceo/ruwuma - various performance improvements, more features, faster-paced development, client/server interop hacks upstream won't accept, etc
• facebook/rocksdb: https://github.com/girlbossceo/rocksdb - liburing build fixes, GCC build fix, and logging callback C API for Rust tracing integration
• tikv/jemallocator: https://github.com/girlbossceo/jemallocator - musl builds seem to be broken on upstream
• zyansheep/rustyline-async: https://github.com/girlbossceo/rustyline-async - tab completion callback and CTRL+\ signal quit event for CLI
• rust-rocksdb/rust-rocksdb: https://github.com/girlbossceo/rust-rocksdb-zaidoon1 - @zaidoon1's fork has quicker updates, more up to date dependencies. Our changes fix musl build issues, Rust part of the logging callback C API, removes unnecessary gtest include, and uses our RocksDB and jemallocator
• tokio-rs/tracing: https://github.com/girlbossceo/tracing - Implements Clone for EnvFilter to support dynamically changing tracing envfilter's alongside other logging/metrics things

Debugging with tokio-console

tokio-console can be a useful tool for debugging and profiling. To make a tokio-console-enabled build of conduwuit, enable the tokio_console feature, disable the default release_max_log_level feature, and set the --cfg tokio_unstable flag to enable experimental tokio APIs. A build might look like this:

RUSTFLAGS="--cfg tokio_unstable" cargo build \
    --release \
    --no-default-features \
    --features=systemd,element_hacks,gzip_compression,brotli_compression,zstd_compression,tokio_console
