Version 0.35.0 (2022-12-27)

PR 419:

  • Rename data's cid_store field to value_store.
  • Canon data is stored with CIDs. Values, tetraplets and canon elements are stored as CIDs resolved with data's value_store, tetraplet_store and canon_store fields respectively.
  • Group stores in the data into cid_info: CidInfo field.

PR 401:
Call result values are stored as CIDs in the data trace. These CIDs refer to a new cid_store data's field that maps a CID string to a value.

Version 0.16.0 (2021-10-18)

PR 154
The json path crate has been removed and changed to custom lambda scheme that have a subset of functionality of json path used by the Aqua compiler. The flattening sign ! is still allowed now, but does nothing.

PR 150, PR 152, PR 153 PR 160
Some parts of the interpreter has been refactored to make it more modular.

Version 0.15.0 (2021-10-04)

PR 140:

  • the interpreter become async, now it's a pure function without any imports from a peer. Instead of calling import call_service from a peer, it now returns call results in the outcome structure, and receives their result in the invoke export.
  • data structure now includes a new field to track last call request id to give peer more freedom.
  • AVM server was completely refactored to support the new interpreter model and to expose a new trait storing data for a node.

Version 0.14.0 (2021-08-24)

PR 74:

  • introduced a new CRDT-like data format for streams:
    • call results contains different values for streams and scalars
    • introduced a new state for fold whose iterables are streams
  • merging scheme was rewritten, and became lazy
  • refactor the internal value mechanism
  • introduced a new instruction (ap responsible for applying json path to scalars and save results as a new scalar or add it to a stream. In the second case it'll produce a new state in a data.
  • introduced a new string literal [] represents empty array

Version 0.10.8 (2021-07-06)

  • improve the error message of the invalid executed state error (PR 121)

Version 0.10.7 (2021-07-01)

  • add support of a particle file vault (PR 120)

Version 0.10.6 (2021-06-10)

  • fixed the error message for incorrect json path in %last_error% (PR 119)

  • json path applied to scalar values becomes non-joinable (PR 118)

Version 0.10.4 (2021-06-09)

  • %last_error% includes peer_id now, that contains id of a peer where an error occurred (PR 117).

Version 0.10.3-0.10.1 (2021-06-04)

  • improved logger initialization and interface for wasm-bindgen target (PR 116, PR 115).

Version 0.10.0 (2021-06-09)

  • %last_error% becomes an object of type
pub struct LastError {
    /// text representation of an instruction that caused the last error
    pub instruction: String,

    /// text representation of an error message
    pub msg: String,
}

and it's possible to address its fields separately: %last_error%.$.instruction, %last_error%.$.msg (PR 112).

Version 0.1.3 (2020-11-11)

  • Switched to the new LALRPOP parser (PR 13):

    • arguments should be wrapped with square braces []
    • empty results in call allowed and lead to forget a call result

  • Added a few benchmarks

  • Fixed behaviour of the Xor instruction with inner Par instructions (PR 19)

  • Iterator in the Fold becomes resolvable (PR 23)

Version 0.1.2 (2020-10-29)

  • Added new data format (PR 12):
    • previously data was a hashmap with variable names to values, and now it is call evidence path that contains call and par evidence states
    • logger is refactored and supports now several log targets
    • interpreter decoupled into two crates: interpreter-lib and interpreter. To build it for the FCE target the fce feature should be specified (fce build --features fce)

Version 0.1.1 (2020-10-23)

  • Added join behaviour (PR 11):
    • if call uses non existing variable, it is just being passed and isn't executed without any error
    • par becomes completed when at least one of its subgraph is completed
