      refactor algebra module (dragoon/komodo!165) · 8c07220b
      STEVAN Antoine authored
      `algebra`, `field` and `linalg` were doing extremely similar things before...
      
      this MR merges them into a single module `algebra`
      - old `algebra` and `field` are at the root of the new `algebra`
      - old `linalg` is now `algebra::linalg`
      
      all references to these have been fixed in the rest of the codebase and the features have been tuned to work fine.

      fix feature dependencies and imports (dragoon/komodo!164) · 15184312
      STEVAN Antoine authored
      in dragoon/komodo!162 and dragoon/komodo!163, i did only run `cargo ... --all-features` without checking the individual features...
      
      this MR adds some `cargo check --features ...` to the `Makefile` and makes sure the imports make sense when compiling a single feature.
      
      > :exclamation: **Important**
      >
      > the other notable change here is that `kzg::commit` has been moved to `zk::ark_commit` and is re-exported from `kzg` as `kzg::commit`.

      refactor repo architecture (dragoon/komodo!161) · 3608e95a
      STEVAN Antoine authored
      ## changelog
      - `src/main.rs` has been moved to a new crate: `bins/saclin` which stands for **S**emi-**A**VID **CLI** in **N**ushell
      - dependencies of `komodo` have been fixed
      - Nushell and Rust tests have been split in the Makefile: by default, only Rust tests will run locally and Nushell tests and examples can be run manually if desired. The CI will still run everything.
      - the README has been updated
      - test images have been moved to `assets/`
      - the majority of the old `./nu-utils/` module have been moved to internals of `./benchmarks/` and imports have been fixed
      - `cargo.nu` has been moved to `./bins/` and a new `./bins/README.md` mentions it
      - `./bins/saclin/` has been created and should be a self-contained Rust crate + Nushell module

      refactor the Nushell modules (dragoon/komodo!158) · dad69f2c
      STEVAN Antoine authored
      this MR is two-fold
      - it restructures the two main Nushell modules so that they are easier to read and use
      - it improves the "run" and "plot" modules for the benchmarks
      
      ## changelog
      - `.nushell/` is now renamed to `nu-utils/`
      - `benchmarks/` is now a valid Nushell module which exports a bunch of modules
        - `benchmarks linalg`: measure and plot linear algebra operations
        - `benchmarks setup`: measure and plot trusted setup building
        - `benchmarks commit`: measure and plot crafting commitments
        - `benchmarks recoding`: measure and plot the recoding of shards
        - `benchmarks fec`: measure and plot FEC operations, such as encoding and recoding, and allow combining these results with the pure recoding ones
      - the submodules of `benchmarks` typically have a `run` and a `plot` command, whith the exception of `benchmarks fec` which has a `run` module and multiple "plot" commands in `benchmarks fec plot`
      - the "run" commands will create a random temp file by default and ask for confirmation otherwise if the output file already exists, unless `--force` is used
      - snippetds in `benchmarks/README.md` have been updated

      add "long full recoding" test (dragoon/komodo!147) · 447e4473
      STEVAN Antoine authored
      this will
      - recode for $\#steps \in [10, 20, 100]$
      - at $t = 0$, $k$ random shards among the $n$ encoded will be selected at random
      - at $t \geq 1$, all $k$ shards will be used to recode $k$ brand new shards
      - make sure the last set of $k$ shards recoded $\#steps$ together can decode the data
      
      ## example with $(k, n) = (3, 5)$ and $\#steps = 3$
      - $(s_i)_{1 \leq i \leq k}$ are the $k$ source shards
      - $(e_j)_{1 \leq j \leq n}$ are the $n$ encoded shards
      - $(m_i)_{1 \leq i \leq k}$ are the $k$ randomly selected shards
      - $(n_i)_{1 \leq i \leq k}$ are the shards after step $1$
      - $(o_i)_{1 \leq i \leq k}$ are the shards after step $2$
      - $(p_i)_{1 \leq i \leq k}$ are the shards after step $3$
      - the $(p_i)_{1 \leq i \leq k}$ will be used for decoding

      working on FEC tests again (dragoon/komodo!146) · 0e229c28
      STEVAN Antoine authored
      - pass `n` to `try_all_decoding_combinations` and don't try to decode when shards have been recoded ($\#shards > n$) and there are no recoded shards in the $k$ combination under review ($\max(is) < n$)
      - pass `recoding_steps` and `should_not_be_decodable` as arguments to `end_to_end_with_recoding_template`
      - fix $n = 5$ => this leads to tests that run in less than 10sec again
      - add $(k, n) = (8, 10)$ => tests still run in less than 13sec
      - split recoding scenarii into "_simple_" and "_chain_"
      - show indices in a "_pretty_" format, i.e. showing indices greater than $n$ as `(n)`, `(n + 1)`, ...

      - `end_to_end` and `end_to_end_with_recoding` now runs for $k \in [3, 5]$ and $\rho \in [\frac{1}{2}, \frac{1}{3}]$ with $n = \lfloor \frac{k}{\rho} \rfloor$
      - all "_$k$ among $n + t$_" combinations are tested with `try_all_decoding_combinations`, possibly with some removals in case recoding is involved with `is_inside`
