rdf-canonize ChangeLog

3.3.0 - 2022-09-17

Added

  • Add optional createMessageDigest factory function for generating an a MessageDigest interface. This allows different hash implementations or even different hash algorithms, including HMACs to be used with URDNA2015. Note that using a different hash algorithm from SHA-256 will change the output.

3.2.1 - 2022-09-02

Fixed

  • Fix typo in unsupported algorithm error.

3.2.0 - 2022-09-02

Changed

  • Test that input is not changed.
  • Optimize quad processing.

3.1.0 - 2022-08-30

Added

  • Allow a maximum number of iterations of the N-Degree Hash Quads algorithm to be set, preventing unusual datasets (and likely meaningless or malicious) from consuming unnecessary CPU cycles. If the set maximum is exceeded then an error will be thrown, terminating the canonize process. This option has only been added to URDNA2015. A future major breaking release is expected to set the maximum number of iterations to a safe value by default; this release is backwards compatible and therefore sets no default. A recommended value is 1, which will cause, at most, each blank node to have the N-degree algorithm executed on it just once.

3.0.0 - 2021-04-07

Changed

  • BREAKING: Only support Node.js >= 12. Remove related tests, dependencies, and generated node6 output.
  • BREAKING: Remove browser bundles. Simplifies package and reduces install size. If you have a use case that requires the bundles, please file an issue.
  • Fix browser override file path style.

2.0.1 - 2021-01-21

Fixed

  • Use setimmediate package for setImmediate polyfill. The previous custom polyfill was removed. This should allow current projects using this package to stay the same and allow an easy future transition to webpack v5.

2.0.0 - 2021-01-20

Removed

  • BREAKING: Removed public API for canonizeSync. It is still available for testing purposes but does not run in the browser.
  • BREAKING: Removed dependency on forge which means that this library will only run in browsers that have support for the WebCrypto API (or an external polyfill for it).
  • BREAKING: Do not expose existing on IdentifierIssuer. The old IDs can be retrieved in order via getOldIds.

Changed

  • General optimizations and modernization of the library.

Added

  • Add getOldIds function to IdentifierIssuer.

1.2.0 - 2020-09-30

Changed

  • Use node-forge@0.10.0.

1.1.0 - 2020-01-17

Changed

  • Optimize away length check on paths.
  • Update node-forge dependency.
  • Update semver dependency.

1.0.3 - 2019-03-06

Changed

  • Update node-forge dependency.

1.0.2 - 2019-02-21

Fixed

  • Fix triple comparator in n-quads parser.

Added

  • Add eslint support.

1.0.1 - 2019-01-23

Changed

  • Remove use of deprecated util.isUndefined(). Avoids unneeded util polyfill in webpack build.

1.0.0 - 2019-01-23

Notes

  • WARNING: This release has a BREAKING change that could cause the canonical N-Quads output to differ from previous releases. Specifically, tabs in literals are no longer escaped. No backwards compatibility mode is provided at this time but if you believe it is needed, please file an issue.
  • If you wish to use the native bindings, you must now install rdf-canonize-native yourself. It is no longer a dependency. See below.

Fixed

Changed

  • Improve N-Quads parsing.
    • Unescape literals.
    • Handle unicode escapes.
  • N-Quad serialization optimization.
    • Varies based on input by roughly ~1-2x.
  • BREAKING: Remove rdf-canonize-native as a dependency. The native bindings will still be used if rdf-canonize-native can be loaded. This means if you want the native bindings you must install them yourself. This change was done due to various problems caused by having any type of dependency involving the native code. With modern runtimes the JavaScript implementation is in many cases faster. The native bindings do have overhead but can be useful in cases where you need to offload canonizing into the background. It is recommended to perform benchmarks to determine which method works best in your case.
  • Update webpack and babel.
  • BREAKING: Remove usePureJavaScript option and make the JavaScript implementation the default. Add explicit useNative option to force the use of the native implementation from rdf-canonize-native. An error will be thrown if native bindings are not available.

0.3.0 - 2018-11-01

Changed

  • BREAKING: Move native support to optional rdf-canonize-native package. If native support is required in your environment then also add a dependency on the rdf-canonize-native package directly. This package only has an optional dependency on the native package to allow systems without native binding build tools to use the JavaScript implementation alone.

Added

  • Istanbul coverage support.

0.2.5 - 2018-11-01

Fixed

  • Accept N-Quads upper case language tag.
  • Improve acceptable N-Quads blank node labels.

0.2.4 - 2018-04-25

Fixed

  • Update for Node.js 10 / OpenSSL 1.1 API.

Changed

  • Update nan dependency for Node.js 10 support.

0.2.3 - 2017-12-05

Fixed

  • Avoid variable length arrays. Not supported by some C++ compilers.

0.2.2 - 2017-12-04

Fixed

  • Use const array initializer sizes.

Changed

  • Comment out debug logging.

0.2.1 - 2017-10-16

Fixed

  • Distribute binding.gyp.

0.2.0 - 2017-10-16

Added

  • Benchmark tool using the same manifests as the test system.
  • Support Node.js 6.
  • Native Node.js addon support for URDNA2015. Improves performance.
  • usePureJavaScript option to only use JavaScript.

0.1.5 - 2017-09-18

Changed

  • BREAKING: Remove Node.js 4.x testing and native support. Use a transpiler such as babel if you need further 4.x support.

0.1.4 - 2017-09-17

Added

  • Expose IdentifierIssuer helper class.

0.1.3 - 2017-09-17

Fixed

  • Fix build.

0.1.2 - 2017-09-17

Changed

  • Change internals to use ES6.
  • Return Promise from API for async method.

0.1.1 - 2017-08-15

Fixed

  • Move node-forge to dependencies.

0.1.0 - 2017-08-15

Added

  • RDF Dataset Normalization async implementation from jsonld.js.
  • webpack support.
  • Split messageDigest into Node.js and browser files.
    • Node.js file uses native crypto module.
    • Browser file uses forge.
  • See git history for all changes.
