Add or remove proof requirements when a request contract’s state changes. When a request sale has completed (for a slot), the host who purchased that slot now must provide regular proofs for the data they are contracted to hold. This is now enforced by adding the slotId to the HashSet of Ids for which to require proofs. When a request has been cancelled (not all slots were filled before the request expired), proofs no longer need to be provided and the slotId is removed from teh HashSet.
Add `isCancelled` and `isSlotCancelled` checks to query the contract state without relying the on the state context variable in the contract. Because contract state can only be updated in a transaction, and the client withdrawing funds is responsible for changing the contract state to “Cancelled”, the `isCancelled` and `isSlotCancelled` functions were introduced to check the state regardless of whether or not the client had already withdrawn their funds.
When a request for storage times out (not enough slots filled), the client will initiate a withdraw request to retrieve its funds out of the contract, setting the state of the request to RequestState.Cancelled. The client will also emit a RequestCancelled event for others to listen to (ie hosts will need to listen for this event to withdraw its collateral).
Add unit test that checks for emission of RequestCancelled after request is purchased request expires.
Update dagger-contracts dependency to commit that holds the changes supporting withdrawing of funds.
Increase blocksize from ~8KiB to ~64KiB and remove useless unbounded prefetching on download
* increased upload/download speed on my Win10 Zen3 box to 50/150 MB/s (with FSStore)
* made manifest files 8x smaller
* two more changes in the tests to make them pass
Closes#263
Make RequestId, SlotId, Nonce, PurcahseId distinct types.
Add/modify conversions to support the distinct type (ABI encoding/decoding, JSON encoding, REST decoding).
Update tests
- rename `ContractId` to `SlotId`
- add `RequestId`, `PurchaseId`, `Nonce` types as aliases of `array[32, byte]`
- rename `Proving.contracts` to `Proving.slots`
- change signatures of `isSlotCancelled` and `isCancelled` to use `SlotId` and `RequestId` types, respectively.
- change all references to `RequestId`, `SlotId`, and `PurchaseId`
The initial goal of this patch was to allow to download of a file via REST API in exactly the same size as it was uploaded, which required adding fields Chunker.offset and Manifest.originalBytes to keep that size. On top of that, we added more integrity checks to operations on Manifest, and reorganized TestNode.nim to test the actual interaction between node.store and node.retrieve operations.
Note that the wire format of Manifest was changed, so we need to recreate all BlockStores.
* Download without padding
* Fixed chunker tests
* Chunker: get rid of RabinChunker
* Verify offset in the chunker tests
* Use manifest.originalBytesPadded in StoreStream.size
* StoreStream: replace emptyBlock with zeroMem
* Manifest.bytes: compute how many bytes corresponding StoreStream(Manifest, pad) will return
* Manifest: verify originalBytes and originalLen on new/encode/decode
Also set originalBytes in each Manifest creation/update scenario
* Manifest: comments, split code into sections
* Reordered parameters to deal with int64 size in 32-bit builds
* TestNode.nim: combine Store and Retrieve tests
1. Instead of copy-pasting code from node.nim, new test calls node.store() and node.retrieve() in order to check that they can correctly store and then retrieve data
2. New test compares only file contents, manifest contents considered an implementation detail
3. New test chunks at odd chunkSize=BlockSize/1.618 in order to ensure that data retrieved correctly even when buffer sizes mismatch
* TestNode.nim: code refactoring
* Manifest.add: one more test
* Manifest.verify: return Result instead of raising Defect
* Node.store: added blockSize parameter
change return type for `method getBlock` from `Future[?!(?Block)]` to
`Future[?!Block]`
use `type BlockNotFoundError = object of CodexError` to differentiate between
"block not found in the store" and other errors
also make some logic and error handling/messages more consistent across
BlockStore implementations
closes#177closes#182closes#210
alternative to #205, #209
* [contracts] ContractInteractions.new() now requires account parameter
* [cli] Only perform Ethereum interactions when --eth-account is specified
* [cli] Add --persistence option that is disabled by default
* [cli] Use Option for ethDeployment parameter
* [node] Better error reporting when Ethereum node cannot be reached
also fix a discrepancy where cli option `--cache-size` is documented as
`0 disables the cache` in `codex/conf.nim`, but previously the value `0` would
result in a cache being constructed with default parameter values for
`CacheStore.new()`
Closes#180
BlockStore API got new return types (rationale in https://github.com/status-im/nim-codex/issues/123#issuecomment-1163797753):
- getBlock: Future[?! (?Block)]
- putBlock/delBlock/listBlocks: Future[?!void]
- hasBlock: Future[?!bool]
Plus refactored readOnce(StoreStream) and check received data in its tests.
And replaced local use of AsyncHeapQueue with seq.sort.
`waitFor` has been moved into the main body of integration test
`nodes negotiate ...` to reduce blockage on the main thread. That change, along
with widening the expiry in `when defined(windows)` (and bumping up
`timeout-minutes` in our CI workflow) allows Windows CI builds to succeed more
consistently, i.e. without timing out.

Integrate dagger contracts from `nim-dagger-contracts` repo.
Add `dagger-contracts`, `nim-web3`, and all of `nim-web3`’s transitive deps as submodule deps to `nim-dagger`. Note: `nim-web3` and its transitive deps may no longer be needed when we switch to `nim-ethers`.
Add a `testContracts` nimble task to test all of the contracts functionality. Namely, this spins up an ethereum simulator, deploys the contracts (in `dagger-contracts`), runs the contract tests, and finally, regardless of success/error, kills the ethereum sim processes. The nimble task can be run with `./env.sh nimble testContracts`.
We also tested `nim-dagger-contracts` as a submodule dep of `nim-dagger`, and while the tests run as expected, the preference is to merge `nim-dagger-contracts` inside of `nim-dagger` for ease of parallel development. There’s also a high probability that `nim-dagger-contracts` is not being used as a dep by other projects. Are there any strong objections to this?
