This migrates everything except the `go-car` librairy: https://github.com/ipfs/boxo/issues/218#issuecomment-1529922103
I didn't migrated everything in the previous release because all the boxo code wasn't compatible with the go-ipld-prime one due to a an in flight (/ aftermath) revert of github.com/ipfs/go-block-format. go-block-format has been unmigrated since slight bellow absolutely everything depends on it that would have required everything to be moved on boxo or everything to optin into using boxo which were all deal breakers for different groups.
This worked fine because lotus's codebase could live hapely on the first multirepo setup however boost is now trying to use boxo's code with lotus's (still on multirepo) setup: https://filecoinproject.slack.com/archives/C03AQ3QAUG1/p1685022344779649
The alternative would be for boost to write shim types which just forward calls and return with the different interface definitions.
Btw why is that an issue in the first place is because unlike what go's duck typing model suggest interfaces are not transparent https://github.com/golang/go/issues/58112, interfaces are strongly typed but they have implicit narrowing. The issue is if you return an interface from an interface Go does not have a function definition to insert the implicit conversion thus instead the type checker complains you are not returning the right type.
Stubbing types were reverted https://github.com/ipfs/boxo/issues/218#issuecomment-1478650351
Last time I only migrated `go-bitswap` to `boxo/bitswap` because of the security issues and because we never had the interface return an interface problem (we had concrete wrappers where the implicit conversion took place).
Previously, we'd use the current head if not otherwise specified, even
when the user specified a epoch. Now:
1. If the user specifies nothing, we use head head's epoch.
2. If the user specifies a tipset and no epoch, we use that tipset and
the epoch of that tipset.
3. If the user specifies an epoch and no tipset, use the tipset at that
epoch (based on the current head).
4. Finally, if the user species both, use both (allowing the
epoch/tipset to disagree).
However, we're leaving the default at 1.25x for backwards compatibility, for now.
Also:
1. Actually use the configured replace fee ratio.
2. Store said ratios as percentages instead of floats. 1.25, or 1+1/(2^2),
can be represented as a float. 1.1, or 1 + 1/(2 * 5), cannot.
fixes#10415
This is now "FVM" native. Changes include:
1. Don't treat "trace" messages like off-chain messages. E.g., don't
include CIDs, versions, etc.
2. Include IPLD codecs where applicable.
3. Remove fields that aren't filled by the FVM (timing, some errors,
code locations, etc.).
This will make `lotus send` mostly just "do what the user wants" in this
case:
1. The user may not explicitly specify a method number.
2. Parameters are automatically cbor-encoded where applicable.
3. The method number is automatically selected based on the
recipient (CreateExternal if sent to the EAM, InvokeEVM otherwise).
The improvements in the range-export code lead to avoid reading most blocks
twice, as well as to allowing some blocks to be written to disk multiple times.
The cache hit-rate went down from being close to 50% to a maximum of 12% at
the very end of the export. The reason is that most CIDs are never read twice
since they are correctly tracked in the CID set.
These numbers do not support the maintenance of the CachingBlockstore
code. Additional testing shows that removing it has similar memory-usage
behaviour and about 5 minute-faster execution (around 10%).
Less code to maintain and less options to mess up with.
This commit moderately refactors the ranged export code. It addresses several
problems:
* Code does not finish cleanly and things hang on ctrl-c
* Same block is read multiple times in a row (artificially increasing cached
blockstore metrics to 50%)
* It is unclear whether there are additional races (a single worker quits
when reaching height 0)
* CARs produced have duplicated blocks (~400k for an 80M-blocks CAR or
so). Some blocks appear up to 5 times.
* Using pointers for tasks where it is not necessary.
The changes:
* Use a FIFO instead of stack: simpler implementation as its own type. This
has not proven to be much more memory-friendly, but it has not made things
worse either.
* We avoid a probably not small amount of allocations by not using
unnecessary pointers.
* Fix duplicated blocks by atomically checking+adding to CID set.
* Context-termination now works correctly. Worker lifetime is correctly tracked and all channels
are closed, avoiding any memory leaks and deadlocks.
* We ensure all work is finished before finishing, something that might have
been broken in some edge cases previously. In practice, we would not have
seen this except perhaps in very early snapshots close to genesis.
Initial testing shows the code is currently about 5% faster. Resulting
snapshots do not have duplicates so they are a bit smaller. We have manually
verified that no CID is lost versus previous results, with both old and recent
snapshots.
This first commit contains the first and second implementation stabs (after
primary review by @hsanjuan), using a stack for task buffering.
Known issues: ctrl-c (context cancellation) results in the export code getting
deadlocked. Duplicate blocks in exports. Duplicate block reads from store.

Standarize cli/code functions similar to: https://github.com/filecoin-project/lotus/pull/9317
- cctx.NArg() instead of cctx.Args().xxx
- Add check for args and print help on functions that did not have it
