v2.8.0

What's Changed

Notable items

• go.mod now specifies Go 1.19.
• ReadWrite: add an alternative FinalizeReadOnly+Close flow by @MichaelMure in #376
  • ReadWrite blockstores can now be left open, but read-only with a new FinalizeReadOnly() method which should be followed-up by a Close() when the blockstore is no longer needed. These two operations are currently combined in the Finalize() method.
• blockstore: fast path for AllKeysChan using the index by @MichaelMure in #372
  • Iterating over the keys in a ReadWrite blockstore is now significantly faster and more efficient
• Add WithTrustedCar() reader option by @hsanjuan in #381
  • A BlockReader can be opened with carv2.WithTrustedCAR(true) to disable block data being hashed and checked against the CID. Where a CAR is from a trusted source this can significantly speed up iterating through the blocks.
• feat: extract specific path, accept stdin as streaming input by @rvagg in #384
  • The car extract command has new superpowers:
    • car extract without a -f input file will read streaming CAR data from stdin
    • car extract -p /path/to/data will apply UnixFS pathing to the extraction and extract a specific file, or directory (including subdirectories)
    • Supplying - as the destination for car extract will send the output to stdout where the output would be a single file.
    • Incomplete DAGs are no longer always fatal during car extract; where possible, missing parts will be skipped, with a notice about what is being skipped provided to stderr.
