fix(cmds): CIDv1 and correct multicodecs in 'block put' and 'cid codecs’ #8568

schomatis · 2021-11-25T14:25:04Z

@lidel's blurb for Release Notes

This PR requires refactor: BlockPutSettings.CidPrefix interface-go-ipfs-core#80 to land first. Go there first.

BREAKING CHANGES

ipfs block commands
- ipfs block put now produces CIDv1 with raw codec by default now
  - ipfs block put --cid-codec makes block put return CID with alternative codec
    - this impacts only the returned CID, it does not trigger any validation or data transformation
    - codec names are validated against tables from https://github.com/multiformats/go-multicodec
  - ipfs block put --format is deprecated. It used incorrect codec names and should be avoided for new deployments. Use it only if you need the old, invalid behavior, namely:
    - ipfs block put --format=v0 will produce CIDv0 (implicit dag-pb)
    - ipfs block put --format=cbor will produce CIDv1 with dag-cbor (!)
    - ipfs block put --format=protobuf will produce CIDv1 with dag-pb (!)
ipfs cid codecs
- it now lists codecs from https://github.com/multiformats/go-multicodec
- ipfs cid codecs --supported can be passed to only show codecs supported in various go-ipfs commands

Depends on:

refactor: BlockPutSettings.CidPrefix interface-go-ipfs-core#80 (need to be merged and released before we can merge this PR)
tidy code generation, add KnownCodes, add Code.Tag method multiformats/go-multicodec#59
~~refactor: remove invalid string2code mappings go-cid#137~~
- not a dependency, we can use old version for now, only aciton here was to remove use of maps that will be removed when the go-cid PR is merged.

TODO:

Add ~~--store-codec~~ --cid-codec sharness tests.
update block and cid command helptext
Update github.com/ipfs/interface-go-ipfs-core dependency with version.
~~Update github.com/ipfs/go-cid dependency with version that includes fix(cmds): CIDv1 and correct multicodecs in 'block put' and 'cid codecs’ #8568~~
- this was descoped, as noted in "Depends on" above
Update github.com/multiformats/go-multicodec dependency with version that includes tidy code generation, add KnownCodes, add Code.Tag method multiformats/go-multicodec#59
Fix sharness test "can set multihash type and length on block put without format" once interface-go-ipfs-core is reviewed and the --format=protobuf backward-compatibility is added back.

Closes #8471

@schomatis : @lidel is going to take this over as it is being used to validate his work in ipfs/go-cid#137 . The issue has been reeassigned.

lidel · 2022-04-11T22:24:20Z

(wip rebase, need to rebase ipfs/interface-go-ipfs-core#80 too and switch this PR to that)

- switches to ipfs/interface-go-ipfs-core#80 (comment) - updates helptext of block commands to reflect the fact we now use CIDs everywhere and document the defaults - add tests for new --cid-codec and old --format behavior

we use it in IPNS-related commands

Ready for review together with ipfs/interface-go-ipfs-core#80

TODO: see if we can error if no format or cid-codec is provided over HTTP RPC (or if the default from CLI applies everywhere).

lidel · 2022-04-19T18:41:44Z

core/commands/block.go

-		cmds.StringOption(mhtypeOptionName, "multihash hash function").WithDefault("sha2-256"),
-		cmds.IntOption(mhlenOptionName, "multihash hash length").WithDefault(-1),
-		cmds.BoolOption(pinOptionName, "pin added blocks recursively").WithDefault(false),
+		cmds.StringOption(blockCidCodecOptionName, "Multicodec to use in returned CID").WithDefault("raw"),


@aschmahmann I did some tests around this and the good news is that I was wrong, there is a way to have unified handling of default opts that works the same in ipfs block put CLI and raw HTTP POST to /api/v0/block/put.

If we keep the .WithDefault("raw") here, then this implicit default is also applied when people use curl against /api/v0/block/put and forget to pass cid-codec. It will also produce good docs at https://docs.ipfs.io/reference/http/api/#api-v0-block-put.

If we want to be extra strict and return error, I'd have to remove WithDefault and add some glue code that detects cidCodec == "" and throws error, but that feels hacky and annoying because it would make cid-codec a mandatory parameter, making it bad UX for the common use case where people are fine with codec being raw.

My vote is to keep WithDefault("raw").

Yep, the only breaking change is:

ipfs block put now produces CIDv1 with raw codec by default now

Which only effects the output CID, but ipfs block put <some-dagpb-stuff>; ipfs block get QmDagPBv0Thing will still work fine. This seems like a not too bad silent breakage, although I'm generally averse to silent breakages. WDYT?

sgtm. Added 0.13 breaking changes section to CHANGELOG.md in 2f5b8a4
