v1.27.0-rc3 Pre-release
Pre-release

This is the third release candidate of the upcoming optional release of Lotus v1.27.0. This feature release includes numerous improvements and enhancements for node operators, RPC- and ETH RPC-providers as well as storage providers. This feature release introduces Curio in Beta release. Check out the Curio Beta release section for how you can get started with Curio.

☢️ Upgrade Warnings ☢️

  • This feature release drops the Raft cluster code experiment from the codebase. This Raft cluster never graduated beyond an experiment, had poor UX (e.g. no way to manage a running cluster, so it didn't provide High Availability), and pulled in a lot of heavy dependencies. We keep the multi-node RPC feature, it is not perfect, but it is useful.
  • Event Database: Two sequential migrations will adjust indexes without altering data or columns, ensuring minimal invasiveness when upgrading to this release. However, these migrations may be time-consuming for nodes with extensive event databases.

Indexers, RPC- and ETH RPC-providers improvements

This release includes a lot of improvements and fixes for indexers, RPC- and ETH RPC-providers. Specifically these PRs:

⭐️ Curio Beta Release ⭐️

Curio, the next generation of Lotus-Miner, also referred to as MinerV2! This release officially transitions Curio into beta and introduces a suite of powerful features designed to enhance your storage operations.

Highlights

  • Curio as MinerV2: Embrace the revolutionary upgrade from Lotus-Miner to Curio. This transition is not just a rebranding—it's an upgrade to a more robust, scalable, and user-friendly version.
  • High Availability: Curio is designed for high availability. You can run multiple instances of Curio nodes to handle similar type of tasks. The distributed scheduler and greedy worker design will ensure that tasks are completed on time despite most partial outages. You can safely update one of your Curio machines without disrupting the operation of the others.
  • Node Heartbeat: Each Curio node in a cluster must post a heartbeat message every 10 minutes in HarmonyDB updating its status. If a heartbeat is missed, the node is considered lost and all tasks can now be scheduled on remaining nodes.
  • Task Retry: Each task in Curio has a limit on how many times it should be tried before being declared lost. This ensures that Curio does not keep retrying bad tasks indefinitely. This safeguards against lost computation time and storage.
  • Polling: Curio avoids overloading nodes with a polling system. Nodes check for tasks they can handle, prioritizing idle nodes for even workload distribution.
  • Simple Configuration Management: The configuration is stored in the database in the forms of layers. These layers can be stacked on top of each other to create a final configuration. Users can reuse these layers to control the behavior of multiple machines without needing to maintain the configuration of each node. Start the binary with the appropriate flags to connect with YugabyteDB and specify which configuration layers to use to get desired behaviour.

v1.26.2

This is a mandatory patch release for the Filecoin network version 22 mainnet upgrade, for all node operators.

There is an update in the upgrade epoch for nv22, you can read the full discussion in Slack here.

The new upgrade epoch is scheduled to be on epoch 3855360 - 2024-04-24 - 14:00:00Z. That means:

  • All mainnet node operators that have upgraded to v1.26.x, must upgrade to this patch release before 2024-04-11T14:00:00Z.
  • All mainnet node operators that are on a version lower the v1.26.x, must upgrade to this patch release before 2024-04-24T14:00:00Z.

Please note that releases v1.26.0 and v1.26.1 have been retracted and should not be used prior to the new network version 22 upgrade epoch.

This patch also includes fixes for node operators who want to index builtin-actor events after the nv22 upgrade. Specifically, it ensures the builtin actor event entries are ordered by insertion order when selected (#11834). It also includes a couple Lotus-Miner patch fixes, ensuring that SnapDeals works properly and are using the new ProveReplicaUpdate3 message after the network version 22 upgrade, ensuring that DDO-sectors has the correct sector expirations, as well as DDO-sector visibility in the lotus-miner sectors list cmd.

The information below is copied from the v1.26.0 release notes and relates to inclusions in the v1.26 series:

This is the stable release for the upcoming MANDATORY Filecoin network upgrade v22, codenamed Dragon 🐉, at epoch 3817920 - 2024-04-11 - 14:00:00Z epoch 3855360 - 2024-04-24 - 14:00:00Z The switch to the new Drand-network will happen exactly 120 epochs (1 hour) after the Dragon-upgrade. This switch has been codenamed Phoenix.

The Filecoin network version 22 delivers the following FIPs:

☢️ Upgrade Warnings ☢️

  • This release requires a minimum Go version of v1.21.7 or higher to successfully build Lotus.
  • SPs: Some SPs has encountered a wdpost with the address didn't have enough funds to send message error error when upgrading to this version. Due to #9746 which was introduced in Lotus v1.25.2, SPs must ensure they have a higher FIL amount in their windowPoSt-wallet then the MaxWindowPoStGasFee setting is. Alternetively they can set the MaximizeWindowPoStFeeCap settting to false.

v13 Builtin Actor Bundle

Builtin actor v13.0.0 is used for supporting this upgrade. Make sure that your lotus actor bundle matches the v13 actors manifest by running the following cli after upgrading:

Migration

We are expecting a bit heavier than normal state migration for this upgrade due to the amount of state changes introduced with Direct Data Onboarding.

All node operators, including storage providers, should be aware that ONE pre-migration is being scheduled 120 epochs before the upgrade. It will take around 10-20 minutes for the pre-migration and less than 30 seconds for the final migration, depending on the amount of historical state in the node blockstore and the hardware specs the node is running on. During this time, expect slower block validation times, increased CPU and memory usage, and longer delays for API queries

We recommend node operators (who haven't enabled splitstore discard mode) that do not care about historical chain states, to prune the chain blockstore by syncing from a snapshot 1-2 days before the upgrade.

You can test out the migration by running running the benchmarking a network migration tutorial.

For certain node operators, such as full archival nodes or systems that need to keep large amounts of state (RPC providers), completing the pre-migration in time before the network upgrade might not be achievable. For those node operators, it is recommended to skip the pre-migration and run the non-cached migration (i.e., just running the migration at the exact upgrade epoch), and schedule for some downtime during the upgrade epoch. Operators of such nodes can read the How to disable premigration in network upgrade tutorial.

Tracing API

Replace the CodeCid field in the message trace (added in 1.23.4) with an InvokedActor field.

Before:

{
    "Msg": {
        "From": ...,
        "To": ...,
        ...
        "CodeCid": ... // The actor's code CID.
    }
    "MsgRct": ...,
    "GasCharges": [],
    "Subcalls": [],
}

After:

{
    "Msg": {
        "From": ...,
        "To": ...
    }
    "InvokedActor": {         // The invoked actor (ommitted if the actor wasn't invoked).
        "Id": 1234,           // The ID of the actor.
        "State": {            // The actor's state object (may change between network versions).
           "Code": ...,       // The actor's code CID.
           "Head": ...,       // The actor's state-root (when invoked).
           "CallSeqNum": ..., // The actor's nonce.
           "Balance": ...,    // The actor's balance (when invoked).
           "Address": ...,    // Delegated address (FEVM only).
        }
    }
    "MsgRct": ...,
    "GasCharges": [],
    "Subcalls": [],
}

This means the trace now contains an accurate "snapshot" of the actor at the time of the call, information that may not be present in the final state-tree (e.g., due to reverts). This will hopefully improve the performance and accuracy of indexing services.

Ethereum Tracing API (trace_block and trace_replayBlockTransactions)

For those with the Ethereum JSON-RPC API enabled, the experimental Ethereum Tracing API has been improved significantly and should be considered "functional". However, it's still new and should be tested extensively before relying on it. This API translates FVM traces to Ethereum-style traces, implementing the OpenEthereum trace_block and trace_replayBlockTransactions APIs.

This release fixes numerous bugs with this API and now ABI-encodes non-EVM inputs/outputs as if they were explicit EVM calls to [handle_filecoin_method][handlefilecoinmethod] for better block explorer compatibility.

However, there are some significant limitations:

  1. The Geth APIs are not implemented, only the OpenEthereum (Erigon, etc.) APIs.
  2. Block rewards are not (yet) included in the trace.
  3. Selfdestruct operations are not included in the trace.
  4. EVM smart contract "create" events always specify 0xfe as the "code" for newly created EVM smart contracts.

Additionally, Filecoin is not Ethereum no matter how much we try to provide API/tooling compatibility. This API attempts to translate Filecoin semantics into Ethereum semantics as accurately as possible, but it's hardly the best source of data unless you need Filecoin to look like an Ethereum compatib...

v1.26.1

RETRACTED: Due to a change in network version 22 upgrade epoch, Lotus v1.26.1 should not be used prior to the new upgrade epoch. See v1.26.2 release notes for details.

This is a patch release for the Calibration network users. The Calibration network is scheduled for an upgrade to include the two additional built-in actor events to ease the transition and observability of DDO for the ecosystem (#964 and #968).

The agreed-upon epoch between the Filecoin implementer team for the update is 1493854, corresponding to 2024-04-03T11:00:00Z. All Calibration network users need to upgrade to this patch release before that.

Lotus Mainnet Users: For users on the Mainnet, the Lotus v1.26.0 release already includes the aforementioned events in preparation for the Mainnet nv22 upgrade. Therefore, both v1.26.0 and v1.26.1 versions are suitable for use on the Mainnet for the coming network version 22 upgrade.

           "Balance": ...,    // The actor's balance (when invoked).
           "Address": ...,    // Delegated address (FEVM only).
        }
    }
    "MsgRct": ...,
    "GasCharges": [],
    "Subcalls": [],
}

This means the trace now contains an accurate "snapshot" of the actor at the time of the call, information that may not be present in the final state-tree (e.g., due to reverts). This will hopefully improve the performance and accuracy of indexing services.

Ethereum Tracing API (trace_block and trace_replayBlockTransactions)

For those with the Ethereum JSON-RPC API enabled, the experimental Ethereum Tracing API has been improved significantly and should be considered "functional". However, it's still new and should be tested extensively before relying on it. This API translates FVM traces to Ethereum-style traces, implementing the OpenEthereum trace_block and trace_replayBlockTransactions APIs.

This release fixes numerous bugs with this API and now ABI-encodes non-EVM inputs/outputs as if they were explicit EVM calls to handle_filecoin_method for better block explorer compatibility.

However, there are some significant limitations:

  1. The Geth APIs are not implemented, only the OpenEthereum (Erigon, etc.) APIs.
  2. Block rewards are not (yet) included in the trace.
  3. Selfdestruct operations are not included in the trace.
  4. EVM smart contract "create" events always specify 0xfe as the "code" for newly created EVM smart contracts.

Additionally, Filecoin is not Ethereum no matter how much we try to provide API/tooling compatibility. This API attempts to translate Filecoin semantics into Ethereum semantics as accurately as possible, but it's hardly the best source of data unless you need Filecoin to look like an Ethereum compatible chain. If you're trying to build a new integration with Filecoin, please use the native StateCompute method instead.

GetActorEventsRaw and SubscribeActorEventsRaw

FIP-0049 introduced Actor Events that can be emitted by user programmed actors. FIP-0083 introduces new events emitted by the builtin Verified Registry, Miner and Market Actors. These new events for builtin actors are being activated with network version 22 to coincide with Direct Data Onboarding as defined in FIP-0076 which introduces additional flexibility for data onboarding. Sector, Deal and DataCap lifecycles can be tracked with these events, providing visibility and options for programmatic responses to changes in state.

Actor events are available on message receipts, but can now be retrieved from a node using the new GetActorEventsRaw and SubscribeActorEventsRaw methods. These methods allow for querying and subscribing to actor events, respectively. They depend on the Lotus node both collecting events (with Fevm.Events.RealTimeFilterAPI and Fevm.Events.HistoricFilterAPI) and being enabled with the new configuration option Events.EnableActorEventsAPI. Note that a Lotus node can only respond to requests for historic events that it retains in its event store.

Both GetActorEventsRaw and SubscribeActorEventsRaw take a filter parameter which can optionally filter events on:

  • Addresses of the actor(s) emitting the event
  • Specific Fields within the event
  • FromHeight and ToHeight to filter events by block height
  • TipSetKey to restrict events contained within a specific tipset

v1.26.0-rc3 Pre-release
Pre-release

This is the third release candidate of the upcoming MANDATORY Lotus v1.26.0 release, which will deliver the Filecoin network version 22, codenamed Dragon 🐉. This third release candidate brings in multiple storage provider fixes, and cleanups for issues encountered during testing in the Calibration network.

This release candidate only has the calibration network to upgrade set, which happened at epoch 1427974, 2024-03-11T14:00:00Z. This release does NOT set the mainnet upgrade epoch, which will be updated in the final release.

The Filecoin network version 22 delivers the following FIPs:

Migration

We are expecting a bit heavier than normal state migration for this upgrade due to the amount of state changes introduced with Direct Data Onboarding.

All node operators, including storage providers, should be aware that ONE pre-migration is being scheduled 120 epochs before the upgrade. It will take around 10-20 minutes for the pre-migration and less than 30 seconds for the final migration, depending on the amount of historical state in the node blockstore and the hardware specs the node is running on. During this time, expect slower block validation times, increased CPU and memory usage, and longer delays for API queries

We recommend node operators (who haven't enabled splitstore discard mode) that do not care about historical chain states, to prune the chain blockstore by syncing from a snapshot 1-2 days before the upgrade.

You can test out the migration by running running the benchmarking a network migration tutorial.

For certain node operators, such as full archival nodes or systems that need to keep large amounts of state (RPC providers), completing the pre-migration in time before the network upgrade might not be achievable. For those node operators, it is recommended to skip the pre-migration and run the non-cached migration (i.e., just running the migration at the exact upgrade epoch), and schedule for some downtime during the upgrade epoch. Operators of such nodes can read the How to disable premigration in network upgrade tutorial.

Replace the CodeCid field in the message trace (added in 1.23.4) with an InvokedActor field.

Before:

}

After:

{
    "Msg": {
        "From": ...,
        "To": ...
    }
    "InvokedActor": {         // The invoked actor (ommitted if the actor wasn't invoked).
        "Id": 1234,           // The ID of the actor.
        "State": {            // The actor's state object (may change between network versions).
           "Code": ...,       // The actor's code CID.
           "Head": ...,       // The actor's state-root (when invoked).
           "CallSeqNum": ..., // The actor's nonce.
           "Balance": ...,    // The actor's balance (when invoked).

This means the trace now contains an accurate "snapshot" of the actor at the time of the call, information that may not be present in the final state-tree (e.g., due to reverts). This will hopefully improve the performance and accuracy of indexing services.

Ethereum Tracing API (trace_block and trace_replayBlockTransactions)

For those with the Ethereum JSON-RPC API enabled, the experimental Ethereum Tracing API has been improved significantly and should be considered "functional". However, it's still new and should be tested extensively before relying on it. This API translates FVM traces to Ethereum-style traces, implementing the OpenEthereum trace_block and trace_replayBlockTransactions APIs.

This release fixes numerous bugs with this API and now ABI-encodes non-EVM inputs/outputs as if they were explicit EVM calls to handle_filecoin_method for better block explorer compatibility.

However, there are some significant limitations:

  1. The Geth APIs are not implemented, only the OpenEthereum (Erigon, etc.) APIs.
  2. Block rewards are not (yet) included in the trace.
  3. Selfdestruct operations are not included in the trace.
  4. EVM smart contract "create" events always specify 0xfe as the "code" for newly created EVM smart contracts.

Additionally, Filecoin is not Ethereum no matter how much we try to provide API/tooling compatibility. This API attempts to translate Filecoin semantics into Ethereum semantics as accurately as possible, but it's hardly the best source of data unless you need Filecoin to look like an Ethereum compatible chain. If you're trying to build a new integration with Filecoin, please use the native StateCompute method instead.

GetActorEvents and SubscribeActorEvents

FIP-0049 introduced Actor Events that can be emitted by user programmed actors. FIP-0083 introduces new events emitted by the builtin Verified Registry, Miner and Market Actors. These new events for builtin actors are being activated with network version 22 to coincide with Direct Data Onboarding as defined in FIP-0076 which introduces additional flexibility for data onboarding. Sector, Deal and DataCap lifecycles can be tracked with these events, providing visibility and options for programmatic responses to changes in state.

Actor events are available on message receipts, but can now be retrieved from a node using the new GetActorEvents and SubscribeActorEvents methods. These methods allow for querying and subscribing to actor events, respectively. They depend on the Lotus node both collecting events (with Fevm.Events.RealTimeFilterAPI and Fevm.Events.HistoricFilterAPI) and being enabled with the new configuration option Events.EnableActorEventsAPI. Note that a Lotus node can only respond to requests for historic events that it retains in its event store.

Both GetActorEvents and SubscribeActorEvents take a filter parameter which can optionally filter events on:

  • Addresses of the actor(s) emitting the event
  • Specific Fields within the event
  • FromHeight and ToHeight to filter events by block height
  • TipSetKey to restrict events contained within a specific tipset

GetActorEvents provides a one-time query for actor events, while SubscribeActorEvents provides a long-lived connection (via websockets) to the Lotus node, allowing for real-time updates on actor events. The subscription can be cancelled by the client at any time.
