Changelog

All notable changes to this project will be documented in this file.

The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.

Unreleased

  • Added a prime256v1-based Identity impl to complement the ed25519 and secp256k1 Identity impls.

[0.32.0] - 2024-01-18

  • Added the chunked wasm API to ic-utils. Existing code that uses install_code should probably update to install, which works the same but silently handles large wasm modules.
  • Added query stats to StatusCallResult.
  • Upgraded ic-certification to v2.2.

[0.31.0] - 2023-11-27

  • Breaking change: Bump candid to 0.10. Downstream libraries need to bump Candid to 0.10 as well.
  • Feat: add idle_cycles_burned_per_day field to StatusCallResult.

[0.30.2] - 2023-11-16

  • Fixed a spurious certificate validation error in the five minutes after a node is added to a subnet

[0.30.1] - 2023-11-15

  • Fixed HyperTransport endpoint construction (// in the format /api/v2//canister/5v3p4-iyaaa-aaaaa-qaaaa-cai/query)

[0.30.0] - 2023-11-07

  • Added node signature certification to query calls, for protection against rogue boundary nodes. This can be disabled with with_verify_query_signatures.
  • Added with_nonce_generation to QueryBuilder for precise cache control.
  • Added the ability to dispatch to multiple URLs to ReqwestTransport and HyperTransport, with a RouteProvider trait and a provided RoundRobinRouteProvider implementation.
  • Added read_subnet_state_raw to Agent and read_subnet_state to Transport for looking up raw state by subnet ID instead of canister ID.
  • Added read_state_subnet_metrics to Agent to access subnet metrics, such as total spent cycles.
  • Types passed to the to_request_id function can now contain nested structs, signed integers, and externally tagged enums.
  • Envelope struct is public also outside of the crate.
  • Remove non-optional ic_api_version field (whose value is not meaningfully populated by the replica) and optional impl_source and impl_revision fields (that are not populated by the replica) from the expected /api/v2/status endpoint response.
  • Drop senders field from user delegations (type Delegation).

[0.29.0] - 2023-09-29

  • Added reserved_cycles_limit to canister creation and canister setting update options.
  • Added reserved_cycles and reserved_cycles_limit to canister status call result.

[0.28.0] - 2023-09-21

  • Added DelegatedIdentity, an Identity implementation for consuming delegations such as those from Internet Identity.
  • Replica protocol type definitions have been moved to an ic-transport-types crate. ic-agent still reexports the ones for its API.
  • The Unknown lookup of a request_status path in a certificate results in an AgentError (the IC returns Absent for non-existing paths).
  • For Canister type, added methods with no trailing underscore: update(), query(), canister_id(), clone_with()

[0.27.0] - 2023-08-30

  • Breaking change: Remove argument builder form ic-utils. CallBuilder::with_arg sets a single argument, instead of pushing a new argument to the list. This function can be called at most once. If it's called multiple times, it panics. If you have multiple arguments, use CallBuilder::with_args((arg1, arg2)) or CallBuilder::set_raw_arg(candid::Encode!(arg1, arg2)?).
  • feat: Added public_key, sign_arbitrary, sign_delegation functions to Identity.
  • Add From trait to coerce candid::Error into ic_agent::AgentError.
  • Add Agent::set_arc_identity method to switch identity.

[0.26.1] - 2023-08-22

Switched from rustls crate to rustls-webpki fork to address https://rustsec.org/advisories/RUSTSEC-2023-0052

[0.26.0] - 2023-08-21

Removed the arc_type feature requirement for candid, in order to avoid deprecation warnings. This is a breaking change. The call and call_and_wait are no longer async fn and instead return a Future or BoxFuture.

[0.25.0] - 2023-07-05

  • Breaking Change: builders are now owning-style rather than borrowing-style; with_arg takes an owned Vec rather than a borrowed Vec
  • Breaking Change: Identity::sign takes &EnvelopeContent rather than the request ID.
  • Bump Candid crate to 0.9.0

[0.24.0] - 2023-05-19

  • fix: Adjust the default polling parameters to provide better UX. Remove the CouldNotReadRootKey error and panic on poisoned mutex.

  • chore: remove deprecated code and fix style

  • Breaking Change: removing the PasswordManager

  • Breaking Change: Enum variant AgentError::ReplicaError is now a tuple struct containing RejectResponse.

  • Handling rejected update calls where status code is 200. See IC-1462

  • Reject code type is changed from u64 to enum RejectCode.

  • Support WASM targets in the browser via wasm-bindgen. Feature wasm-bindgen required.

  • Do not send certificate_version on HTTP Update requests

  • Update certificate_version to u16 instead of u128, fixes an issue where the asset canister always responds with v1 response verification

ic-certification

  • Breaking change: Content and path storage has been changed from a Cow<[u8]> to a user-provided T: AsRef<u8>, removing the lifetime from various types.

icx-cert

  • Fixed issue where a missing request header caused the canister to not respond with an ic-certificate header.

[0.23.2] - 2023-04-21

  • Expose the root key to clients through read_root_key

[0.23.1] - 2023-03-09

  • Add lookup_subtree method to HashTree & HashTreeNode to allow for subtree lookups.
  • Derive Clone on Certificate and Delegation structs.
  • Add certificate version to http_request canister interface.
  • (ic-utils) Add specified_id in provisional_create_canister_with_cycles.

[0.23.0] - 2022-12-01

  • Remove garcon from API. Callers can remove the dependency and any usages of it; all waiting functions no longer take a waiter parameter.
  • Create ic-certification crate and move HashTree and Certificate types.

[0.22.0] - 2022-10-17

  • Drop disable_range_check flag from certificate delegation checking.

[0.21.0] - 2022-10-03

  • Update candid to v0.8.0.
  • Move hash_tree from ic-types and no more re-export ic-types.

[0.20.1] - 2022-09-27

  • Set default-features = false for ic-agent interdependencies to reduce unused nested dependencies.
  • Bump candid to 0.7.18.

ic-asset

  • Fixed custom configured HTTP headers - no longer is the header's value wrapped with double quotes.

ic-agent

  • Switched to ic-verify-bls-signature crate for verify BLS signatures
  • Added new hyper transport HyperReplicaV2Transport
  • Added Agent::set_identity method (#379)
  • Updated lookup_request_status method to handle proofs of absent paths in certificates.

ic-utils

  • Make it possible to specify effective canister id in CreateCanisterBuilder

[0.20.0] - 2022-07-14

Breaking change: Updated to ic-types 0.4.0

  • Remove PrincipalInner
    • Principal directly holds len and bytes fields
  • PrincipalError enum has different set of variants reflecting changes in from_text logic.
  • from_text accepts input containing uppercase letters which results in Err before.
  • from_text verifies CRC32 check sequence

ic-asset

Added support configurable inclusion and exclusion of files and directories (including dotfiles and dot directories), done via .ic-assets.json config file:

  • example of .ic-assets.json file format: 
    [
    {
        "match": ".*",
        "cache": {
            "max_age": 20
        },
        "headers": {
            "X-Content-Type-Options": "nosniff"
        },
        "ignore": false
    }
]
  • see PR and tests for more examples

Added support for configuring HTTP headers for assets in asset canister (via .ic-assets.json config file):

  • example of .ic-assets.json file format: 
    [
    {
        "match": "*",
        "cache": {
            "max_age": 20
        },
        "headers": {
            "X-Content-Type-Options": "nosniff"
        }
    },
    {
        "match": "**/*",
        "headers": null
    },
]
  • headers from multiple applicable rules are being stacked/concatenated, unless null is specified, which resets/empties the headers. Both "headers": {} and absence of headers don't have any effect on end result.

[0.19.0] - 2022-07-06

ic-asset

Added support for asset canister config files in ic-assets.

  • reads configuration from .ic-assets.json config files if placed inside assets directory, multiple config files can be used (nested in subdirectories)
  • runs successfully only if the config file is right format (valid JSON, valid glob pattern, JSON fields in correct format)
  • example of .ic-assets.json file format: 
    [
    {
        "match": "*",
        "cache": {
            "max_age": 20
        }
    }
]
  • works only during asset creation
  • the config file is being taken into account only when calling ic_asset::sync (i.e. dfx deploy or icx-asset sync)

[0.18.0] - 2022-06-23

ic-asset

Breaking change: ic-asset::sync() now synchronizes from multiple source directories.

This is to allow for configuration files located alongside assets in asset source directories.

Also, ic-asset::sync:

  • skips files and directories that begin with a ".", as dfx does when copying assets to an output directory.
  • reports an error if more than one asset file would resolve to the same asset key

[0.17.1] - 2022-06-22

agent-rs/349 feat: add with_max_response_body_size to ReqwestHttpReplicaV2Transport

[0.17.0] - 2022-05-19

Updated dependencies. Some had breaking changes: k256 0.11, pkcs 0.9, and sec1 0.3.

Fixed a potential panic in secp256k1 signature generation.

[0.16.0] - 2022-04-28

Added ReqwestHttpReplicaV2Transport::create_with_client.

Remove openssl in favor of pure rust libraries.

Updated minimum version of reqwest to 0.11.7. This is to avoid the following error, seen with reqwest 0.11.6:

Unknown TLS backend passed to use_preconfigured_tls

Updated wallet interface for 128-bit API.

Remove parameterized canister pattern. Use WalletCanister::create rather than Wallet::create.

wallet_send takes Principal instead of &Canister.

[0.15.0] - 2022-03-28

Updated ic_utils::interfaces::http_request structures to use &str to reduce copying.

Removed Deserialize from HttpRequest.

Changed HttpResponse to be generic over entire callback instead of just ArgToken.

Added HttpRequestStreamingCallbackAny to deserialize any callback, regardless of signature.

Added conversion helpers for HttpResponse, StreamingStrategy and CallbackStrategy across generics.

Changes to Canister<HttpRequestCanister> interface.

  • Made http_request, http_request_update, and http_request_stream_callback more generic and require fewer string copies.
  • Added _custom variants to enable custom token deserialization.

[0.14.0] - 2022-03-17

Introduced HttpRequestStreamingCallback to work around dfinity/candid#273.

Response certificate verification will check that the canister id falls within the range of valid canister ids for the subnet.

[0.13.0] - 2022-03-07

Secp256k1 identity now checks if a curve actually uses the secp256k1 parameters. It cannot be used to load non-secp256k1 identities anymore.

Data type of cycles changed to u128 (was u64).

fetch_root_key() only fetches on the first call.

Re-genericized Token to allow use of an arbitrary Token type with StreamingStrategy.

[0.12.1] - 2022-02-09

Renamed BatchOperationKind._Clear to Clear for compatibility with the certified assets canister. This avoids decode errors, even though the type isn't referenced here.

[0.12.0] - 2022-02-03

Changed the 'HttpRequest.upgrade' field to 'Option' from 'bool'.

[0.11.1] - 2022-01-10

The lookup_value function now takes generics which can be iterated over (IntoIterator<Item = &'p Label>) and transformed into a Vec<Label>, rather than just a Vec<Label>.

[0.11.0] - 2022-01-07

Breaking change: Updated to ic-types 0.3.0

The lookup_path method now takes an Iterator<Label> rather than an AsRef<[Label]>

[0.10.2] - 2021-12-22

ic-agent

Added support for upgrading HTTP requests (http_request_update method)

[0.10.1] - 2021-12-10

Updated crate dependencies, most notably updating rustls, removing the direct dependency on webpki-roots, and allowing consumers of ic-agent to update to reqwest 0.11.7.

ic-agent

Added: read_state_canister_metadata

Implements https://github.com/dfinity-lab/ic-ref/pull/371

ic-asset

Fixed: sync and upload will now attempt retries as expected

Fixed a defect in asset synchronization where no retries would be attempted after the first 30 seconds overall.

icx-asset

Fixed: now works with secp256k1 .pem files.

[0.10.0] - 2021-11-15

Unified all version numbers and removed the zzz-release tool.

ic-agent

Fixed: rewrite all *.ic0.app domains to ic0.app to avoid redirects.

icx-cert

New feature: Add --accept-encoding parameter

It's now possible to specify which encodings will be accepted. The default (and previous) behavior is to accept only the identity encoding. Specifying encodings that browsers more commonly accept demonstrates the difference in the returned data and certificate.

For example, here is the data and certificate returned when only accepting the identity encoding.

$ cargo run -p icx-cert -- print 'http://localhost:8000/index.js?canisterId=ryjl3-tyaaa-aaaaa-aaaba-cai'
DATA HASH: 1495cd574831c23b4db97bc3860666ea495386f0ef0dab73c23ef31db5aa2765
    Label("/index.js", Leaf(0x1495cd574831c23b4db97bc3860666ea495386f0ef0dab73c23ef31db5aa2765)),

Here is an example accepting the gzip encoding (as most browsers do), showing that the canister responded with different data having a different data hash.

$ cargo run -p icx-cert -- print --accept-encoding gzip 'http://localhost:8000/index.js?canisterId=ryjl3-tyaaa-aaaaa-aaaba-cai'
DATA HASH: 1770e76af0816ba951320c03eab1263c43de7ac4b0558dd9049cc532b7d6cd01
    Label("/index.js", Leaf(0x1495cd574831c23b4db97bc3860666ea495386f0ef0dab73c23ef31db5aa2765)),

icx-proxy
