multiformats 1.4.0

Core library for parsing IPFS-related things. This package is mainly used by https://atprotodart.com packages.

Release Note

1.4.0

• fix: dagCborEncode keeps its documented ArgumentError/InvalidCidError contract for a sole-$bytes map whose value is not valid base64, which previously leaked a raw FormatException — reachable from user-supplied $unknown data.
• fix: a sole-$link or sole-$bytes map whose value is not a String now throws ArgumentError instead of being silently encoded as an ordinary one-entry map, which turned a typo into a valid-looking but wrong CID.
• fix: encoding a value nested deeper than 1024 containers throws ArgumentError instead of blowing the stack with a StackOverflowError that callers do not catch.

1.3.0

• feat: added dagCborEncode, a canonical DAG-CBOR encoder (length-first map-key ordering, minimal-length integers, tag-42 CID links, and the atproto $link/$bytes map forms). Its output is exact on both the Dart VM and the web, so a record's bytes — and therefore its CID — can be computed locally.

1.2.0

• feat: CID.toAtprotoJson() emits the atproto data-model {$link: ...} form (toJson continues to emit DAG-JSON {/: ...}; fromJson accepts both).
• fix: the bytes getter returns an unmodifiable view, so external mutation can no longer corrupt a CID or desync its cached hashCode.
• fix: CID.parse rejects uppercase base32 bodies, and invalid base32 characters raise InvalidCidError instead of a raw FormatException.

1.1.0

• fix: the dag-pb multicodec was wrong (0x55, which is actually raw). Added correct raw(0x55), dagPb2(0x70) and dagCbor(0x71) entries and fixed isDagPb/format checks so atproto blob CIDs are classified correctly and real dag-pb is no longer rejected.
• chore: deprecated the incorrect dagPb/dabCbor enum values (kept for a deprecation cycle).
• feat: added CID.createFromBytes (binary overload) and a single-decode parse.
• feat: CID.fromJson now accepts the atproto {"$link": <cid>} shape in addition to the DAG-JSON {"/": <cid>} shape, so atproto JSON round-trips (toJson still emits /). A missing/non-string value now throws a typed InvalidCidError instead of a TypeError.
• perf: cache normalized bytes and hashCode instead of recomputing on every access.

1.0.3

• fix: CID == now returns false for different-length or non-CID operands instead of throwing a RangeError/TypeError.
