## `cuprate-benchmark`
This crate links all benchmarks together into a single binary that can be run as: `cuprate-benchmark`.
`cuprate-benchmark` will run all enabled benchmarks sequentially and print data at the end.
## Benchmarks
Benchmarks are opt-in and enabled via features.
| Feature | Enables which benchmark crate? |
|----------|--------------------------------|
| example | cuprate-benchmark-example |
| database | cuprate-benchmark-database |
## Features
These are features that aren't for enabling benchmarks, but rather for other things.
Since `cuprate-benchmark` is built right before it is ran,
these features almost act like command line arguments.
| Features | Does what |
|----------|-----------|
| json | Prints JSON timings instead of a markdown table
| trace | Use the `trace` log-level
| debug | Use the `debug` log-level
| warn | Use the `warn` log-level
| info | Use the `info` log-level (default)
| error | Use the `error` log-level

## `cuprate-benchmark-lib`
This crate is the glue between
[`cuprate-benchmark`](https://github.com/Cuprate/cuprate/tree/benches/benches/benchmark/bin)
and all the benchmark crates.
It defines the [`crate::Benchmark`] trait, which is the behavior of all benchmarks.
See the [`cuprate-benchmark-example`](https://github.com/Cuprate/cuprate/tree/benches/benches/benchmark/example)
crate to see an example implementation of this trait.
After implementing this trait, a few steps must
be done such that the `cuprate-benchmark` binary
can actually run your benchmark crate; see the
[`Benchmarking` section in the Architecture book](https://architecture.cuprate.org/benchmarking/intro.html)
to see how to do this.

## `cuprate-criterion-example`
An example of using Criterion for benchmarking Cuprate crates.
Consider copy+pasting this crate to use as a base when creating new Criterion benchmark crates.
## `src/`
Benchmark crates have a `benches/` ran by `cargo bench`, but they are also crates themselves,
as in, they have a `src` folder that `benches/` can pull code from.
The `src` directories in these benchmarking crates are usually filled with
helper functions, types, etc, that are used repeatedly in the benchmarks.
## `benches/`
These are the actual benchmarks ran by `cargo bench`.

# Creating
Creating a new Criterion-based benchmarking crate for one of Cuprate's crates is relatively simple,
although, it requires knowledge of how to use Criterion first:
1. Read the `Getting Started` section of <https://bheisler.github.io/criterion.rs/book>
2. Copy [`benches/criterion/example`](https://github.com/Cuprate/cuprate/tree/main/benches/criterion/example) as base
3. Get started
## Naming
New benchmark crates using Criterion should:
- Be in [`benches/criterion/`](https://github.com/Cuprate/cuprate/tree/main/benches/criterion/)
- Be in the `cuprate-criterion-$CRATE_NAME` format
For a real example, see:
[`cuprate-criterion-json-rpc`](https://github.com/Cuprate/cuprate/tree/main/benches/criterion/cuprate-json-rpc).
## Workspace
Finally, make sure to add the benchmark crate to the workspace
[`Cargo.toml`](https://github.com/Cuprate/cuprate/blob/main/Cargo.toml) file.
Your benchmark is now ready to be ran.

# Criterion
Each sub-directory in [`benches/criterion/`](https://github.com/Cuprate/cuprate/tree/main/benches/criterion) is a crate that uses [Criterion](https://bheisler.github.io/criterion.rs/book) for timing single functions and/or groups of functions.
They are generally be small in scope.

# Running
To run all Criterion benchmarks, run this from the repository root:
```bash
cargo bench
```
To run specific package(s), use:
```bash
cargo bench --package $CRITERION_BENCHMARK_CRATE_NAME
```
For example:
```bash
cargo bench --package cuprate-criterion-json-rpc

# Creating
New benchmarks are plugged into `cuprate-benchmark` by:
1. Implementing `cuprate_benchmark_lib::Benchmark`
1. Registering the benchmark in the `cuprate_benchmark` binary
See [`benches/benchmark/example`](https://github.com/Cuprate/cuprate/tree/main/benches/benchmark/example)
for an example.
## Creating the benchmark crate
Before plugging into `cuprate-benchmark`, your actual benchmark crate must be created:
1. Create a new crate inside `benches/benchmark` (consider copying `benches/benchmark/example` as a base)
1. Pull in `cuprate_benchmark_lib` as a dependency
1. Create a benchmark
1. Implement `cuprate_benchmark_lib::Benchmark`
New benchmark crates using `cuprate-database` should:
- Be in [`benches/benchmark/`](https://github.com/Cuprate/cuprate/tree/main/benches/benchmark/)
- Be in the `cuprate-benchmark-$CRATE_NAME` format
For a real example, see:
[`cuprate-benchmark-database`](https://github.com/Cuprate/cuprate/tree/main/benches/benchmark/cuprate-database).
## `cuprate_benchmark_lib::Benchmark`
This is the trait that standardizes all benchmarks ran under `cuprate-benchmark`.
It must be implemented by your benchmarking crate.
See `cuprate-benchmark-lib` crate documentation for a user-guide: <https://doc.cuprate.org/cuprate_benchmark_lib>.
## Adding a feature to `cuprate-benchmark`
After your benchmark's behavior is defined, it must be registered
in the binary that is actually ran: `cuprate-benchmark`.
If your benchmark is new, add a new crate feature to [`cuprate-benchmark`'s Cargo.toml file](https://github.com/Cuprate/cuprate/tree/main/benches/benchmark/bin/Cargo.toml) with an optional dependency to your benchmarking crate.
Please remember to edit the feature table in the
[`README.md`](https://github.com/Cuprate/cuprate/tree/main/benches/benchmark/bin/README.md) as well!
## Adding to `cuprate-benchmark`'s `main()`
After adding your crate's feature, add a conditional line that run the benchmark
if the feature is enabled to the `main()` function:
For example, if your crate's name is `egg`:
```rust
cfg_if! {
if #[cfg(feature = "egg")] {
run::run_benchmark::<cuprate_benchmark_egg::Benchmark>(&mut timings);
}
}
```
## Workspace
Finally, make sure to add the benchmark crate to the workspace
[`Cargo.toml`](https://github.com/Cuprate/cuprate/blob/main/Cargo.toml) file.
Your benchmark is now ready to be ran.

# cuprate-benchmark
Cuprate has 2 custom crates for general benchmarking:
- `cuprate-benchmark`; the actual binary crate ran
- `cuprate-benchmark-lib`; the library that other crates hook into
The abstract purpose of `cuprate-benchmark` is very simple:
1. Set-up the benchmark
1. Start timer
1. Run benchmark
1. Output data
`cuprate-benchmark` runs the benchmarks found in [`benches/benchmark/cuprate-*`](https://github.com/Cuprate/cuprate/tree/main/benches/benchmark).
`cuprate-benchmark-lib` defines the `Benchmark` trait that all
benchmark crates implement to "plug-in" to the benchmarking harness.

# ⚪️ Benchmarking # Benchmarking
Cuprate has 2 types of benchmarks:
- [Criterion](https://bheisler.github.io/criterion.rs/book/user_guide/advanced_configuration.html) benchmarks
- `cuprate-benchmark` benchmarks
Criterion is used for micro benchmarks; they time single functions, groups of functions, and generally are small in scope.
`cuprate-benchmark` and [`cuprate-benchmark-lib`](https://doc.cuprate.org/cuprate_benchmark_lib) are custom in-house crates Cuprate uses for macro benchmarks; these test sub-systems, sections of a sub-system, or otherwise larger or more complicated code that isn't well-suited for micro benchmarks.
## File layout and purpose
All benchmarking related files are in the [`benches/`](https://github.com/Cuprate/cuprate/tree/main/benches) folder.
This directory is organized like such:
| Directory | Purpose |
|-------------------------------|---------|
| [`benches/criterion/`](https://github.com/Cuprate/cuprate/tree/main/benches/criterion) | Criterion (micro) benchmarks
| `benches/criterion/cuprate-*` | Criterion benchmarks for the crate with the same name
| [`benches/benchmark/`](https://github.com/Cuprate/cuprate/tree/main/benches/benchmark) | Cuprate's custom benchmarking files
| [`benches/benchmark/bin`](https://github.com/Cuprate/cuprate/tree/main/benches/benchmark/bin) | The `cuprate-benchmark` crate; the actual binary run that links all benchmarks
| [`benches/benchmark/lib`](https://github.com/Cuprate/cuprate/tree/main/benches/benchmark/lib) | The `cuprate-benchmark-lib` crate; the benchmarking framework all benchmarks plug into
| `benches/benchmark/cuprate-*` | `cuprate-benchmark` benchmarks for the crate with the same name

# Monero oddities
This section is a list of any peculiar, interesting,
or non-standard behavior that Monero has that is not
planned on being changed or deprecated.
This section exists to hold all the small yet noteworthy knowledge in one place,
instead of in any single contributor's mind.
These are usually behaviors stemming from implementation rather than protocol/cryptography.
## Formatting
This is the markdown formatting for each entry in this section.
If applicable, consider using this formatting when adding to this section.
```md
# <concise_title_of_the_behavior>
## What
A detailed description of the behavior.
## Expected
The norm or standard behavior that is usually expected.
## Why
The reasoning behind why this behavior exists and/or
any links to more detailed discussion on the behavior.
## Affects
A (potentially non-exhaustive) list of places that this behavior can/does affect.
## Example
An example link or section of code where the behavior occurs.
## Source
A link to original `monerod` code that defines the behavior.

# Little-endian IPv4 addresses
## What
Monero encodes IPv4 addresses in [little-endian](https://en.wikipedia.org/wiki/Endianness) byte order.
## Expected
In general, [networking-related protocols/code use _networking order_ (big-endian)](https://en.wikipedia.org/wiki/Endianness#Networking).
## Why
TODO
- <https://github.com/monero-project/monero/issues/3826>
- <https://github.com/monero-project/monero/pull/5544>
## Affects
Any representation and (de)serialization of IPv4 addresses must keep little
endian in-mind, e.g. the P2P wire format or `int` encoded IPv4 addresses in RPC.
For example, [the `ip` field in `set_bans`](https://www.getmonero.org/resources/developer-guides/daemon-rpc.html#set_bans).
For Cuprate, this means Rust's [`Ipv4Addr::from_bits/from`](https://doc.rust-lang.org/1.82.0/src/core/net/ip_addr.rs.html#1182) cannot be used in these cases as [it assumes big-endian encoding](https://doc.rust-lang.org/1.82.0/src/core/net/ip_addr.rs.html#540).
