This commit systematically rebrands various references from Parity Technologies' Polkadot/Substrate ecosystem to PezkuwiChain within the kurdistan-sdk. Key changes include: - Updated external repository URLs (zombienet-sdk, parity-db, parity-scale-codec, wasm-instrument) to point to pezkuwichain forks. - Modified internal documentation and code comments to reflect PezkuwiChain naming and structure. - Replaced direct references to with or specific paths within the for XCM, Pezkuwi, and other modules. - Cleaned up deprecated issue and PR references in various and files, particularly in and modules. - Adjusted image and logo URLs in documentation to point to PezkuwiChain assets. - Removed or rephrased comments related to external Polkadot/Substrate PRs and issues. This is a significant step towards fully customizing the SDK for the PezkuwiChain ecosystem.

//! This module allows for inspection and instrumentation, i.e. modifying the module to alter it's
|
|
//! structure or behavior, of a wasm module.
|
|
//!
|
|
//! ## Instrumentation
|
|
//!
|
|
//! In ideal world, there would be no instrumentation. However, in the real world the execution
|
|
//! engines we use are somewhat limited in their APIs or abilities.
|
|
//!
|
|
//! To give you some examples:
|
|
//!
|
|
//! We need to reset the globals because when we
|
|
//! execute the Bizinikiwi Runtime, we do not drop and create the instance anew, instead
|
|
//! we restore some selected parts of the state.
|
|
//!
|
|
//! - stack depth metering can be performed via instrumentation or deferred to the engine and say be
|
|
//! added directly in machine code. Implementing this in machine code is rather cumbersome so
|
|
//! instrumentation looks like a good solution.
|
|
//!
|
|
//! Stack depth metering is needed to make a wasm blob
|
|
//! execution deterministic, which in turn is needed by the Teyrchain Validation Function in
|
|
//! Pezkuwi.
|
|
//!
|
|
//! ## Inspection
|
|
//!
|
|
//! Inspection of a wasm module may be needed to extract some useful information, such as to extract
|
|
//! data segment snapshot, which is helpful for quickly restoring the initial state of instances.
|
|
//! Inspection can be also useful to prove that a wasm module possesses some properties, such as,
|
|
//! is free of any floating point operations, which is a useful step towards making instances
|
|
//! produced from such a module deterministic.
