core/types: support for optional blob sidecar in BlobTx (#27841) This PR removes the newly added txpool.Transaction wrapper type, and instead adds a way of keeping the blob sidecar within types.Transaction. It's better this way because most code in go-ethereum does not care about blob transactions, and probably never will. This will start mattering especially on the client side of RPC, where all APIs are based on types.Transaction. Users need to be able to use the same signing flows they already have. However, since blobs are only allowed in some places but not others, we will now need to add checks to avoid creating invalid blocks. I'm still trying to figure out the best place to do some of these. The way I have it currently is as follows: - In block validation (import), txs are verified not to have a blob sidecar. - In miner, we strip off the sidecar when committing the transaction into the block. - In TxPool validation, txs must have a sidecar to be added into the blobpool. - Note there is a special case here: when transactions are re-added because of a chain reorg, we cannot use the transactions gathered from the old chain blocks as-is, because they will be missing their blobs. This was previously handled by storing the blobs into the 'blobpool limbo'. The code has now changed to store the full transaction in the limbo instead, but it might be confusing for code readers why we're not simply adding the types.Transaction we already have. Code changes summary: - txpool.Transaction removed and all uses replaced by types.Transaction again - blobpool now stores types.Transaction instead of defining its own blobTx format for storage - the blobpool limbo now stores types.Transaction instead of storing only the blobs - checks to validate the presence/absence of the blob sidecar added in certain critical places

all: replace log15 with slog (#28187) This PR replaces Geth's logger package (a fork of [log15](https://github.com/inconshreveable/log15)) with an implementation using slog, a logging library included as part of the Go standard library as of Go1.21. Main changes are as follows: * removes any log handlers that were unused in the Geth codebase. * Json, logfmt, and terminal formatters are now slog handlers. * Verbosity level constants are changed to match slog constant values. Internal translation is done to make this opaque to the user and backwards compatible with existing `--verbosity` and `--vmodule` options. * `--log.backtraceat` and `--log.debug` are removed. The external-facing API is largely the same as the existing Geth logger. Logger method signatures remain unchanged. A small semantic difference is that a `Handler` can only be set once per `Logger` and not changed dynamically. This just means that a new logger must be instantiated every time the handler of the root logger is changed. ---- For users of the `go-ethereum/log` module. If you were using this module for your own project, you will need to change the initialization. If you previously did ```golang log.Root().SetHandler(log.LvlFilterHandler(log.LvlInfo, log.StreamHandler(os.Stderr, log.TerminalFormat(true)))) ``` You now instead need to do ```golang log.SetDefault(log.NewLogger(log.NewTerminalHandlerWithLevel(os.Stderr, log.LevelInfo, true))) ``` See more about reasoning here: https://github.com/ethereum/go-ethereum/issues/28558#issuecomment-1820606613

all: replace log15 with slog (#28187) This PR replaces Geth's logger package (a fork of [log15](https://github.com/inconshreveable/log15)) with an implementation using slog, a logging library included as part of the Go standard library as of Go1.21. Main changes are as follows: * removes any log handlers that were unused in the Geth codebase. * Json, logfmt, and terminal formatters are now slog handlers. * Verbosity level constants are changed to match slog constant values. Internal translation is done to make this opaque to the user and backwards compatible with existing `--verbosity` and `--vmodule` options. * `--log.backtraceat` and `--log.debug` are removed. The external-facing API is largely the same as the existing Geth logger. Logger method signatures remain unchanged. A small semantic difference is that a `Handler` can only be set once per `Logger` and not changed dynamically. This just means that a new logger must be instantiated every time the handler of the root logger is changed. ---- For users of the `go-ethereum/log` module. If you were using this module for your own project, you will need to change the initialization. If you previously did ```golang log.Root().SetHandler(log.LvlFilterHandler(log.LvlInfo, log.StreamHandler(os.Stderr, log.TerminalFormat(true)))) ``` You now instead need to do ```golang log.SetDefault(log.NewLogger(log.NewTerminalHandlerWithLevel(os.Stderr, log.LevelInfo, true))) ``` See more about reasoning here: https://github.com/ethereum/go-ethereum/issues/28558#issuecomment-1820606613

core/types: support for optional blob sidecar in BlobTx (#27841) This PR removes the newly added txpool.Transaction wrapper type, and instead adds a way of keeping the blob sidecar within types.Transaction. It's better this way because most code in go-ethereum does not care about blob transactions, and probably never will. This will start mattering especially on the client side of RPC, where all APIs are based on types.Transaction. Users need to be able to use the same signing flows they already have. However, since blobs are only allowed in some places but not others, we will now need to add checks to avoid creating invalid blocks. I'm still trying to figure out the best place to do some of these. The way I have it currently is as follows: - In block validation (import), txs are verified not to have a blob sidecar. - In miner, we strip off the sidecar when committing the transaction into the block. - In TxPool validation, txs must have a sidecar to be added into the blobpool. - Note there is a special case here: when transactions are re-added because of a chain reorg, we cannot use the transactions gathered from the old chain blocks as-is, because they will be missing their blobs. This was previously handled by storing the blobs into the 'blobpool limbo'. The code has now changed to store the full transaction in the limbo instead, but it might be confusing for code readers why we're not simply adding the types.Transaction we already have. Code changes summary: - txpool.Transaction removed and all uses replaced by types.Transaction again - blobpool now stores types.Transaction instead of defining its own blobTx format for storage - the blobpool limbo now stores types.Transaction instead of storing only the blobs - checks to validate the presence/absence of the blob sidecar added in certain critical places

Internal translation is done to make this opaque to the user and backwards compatible with existing `--verbosity` and `--vmodule` options. * `--log.backtraceat` and `--log.debug` are removed. The external-facing API is largely the same as the existing Geth logger. Logger method signatures remain unchanged. A small semantic difference is that a `Handler` can only be set once per `Logger` and not changed dynamically. This just means that a new logger must be instantiated every time the handler of the root logger is changed. ---- For users of the `go-ethereum/log` module. If you were using this module for your own project, you will need to change the initialization. If you previously did ```golang log.Root().SetHandler(log.LvlFilterHandler(log.LvlInfo, log.StreamHandler(os.Stderr, log.TerminalFormat(true)))) ``` You now instead need to do ```golang log.SetDefault(log.NewLogger(log.NewTerminalHandlerWithLevel(os.Stderr, log.LevelInfo, true))) ``` See more about reasoning here: https://github.com/ethereum/go-ethereum/issues/28558#issuecomment-1820606613

core/types: support for optional blob sidecar in BlobTx (#27841) This PR removes the newly added txpool.Transaction wrapper type, and instead adds a way of keeping the blob sidecar within types.Transaction. It's better this way because most code in go-ethereum does not care about blob transactions, and probably never will. This will start mattering especially on the client side of RPC, where all APIs are based on types.Transaction. Users need to be able to use the same signing flows they already have. However, since blobs are only allowed in some places but not others, we will now need to add checks to avoid creating invalid blocks. I'm still trying to figure out the best place to do some of these. The way I have it currently is as follows: - In block validation (import), txs are verified not to have a blob sidecar. - In miner, we strip off the sidecar when committing the transaction into the block. - In TxPool validation, txs must have a sidecar to be added into the blobpool. - Note there is a special case here: when transactions are re-added because of a chain reorg, we cannot use the transactions gathered from the old chain blocks as-is, because they will be missing their blobs. This was previously handled by storing the blobs into the 'blobpool limbo'. The code has now changed to store the full transaction in the limbo instead, but it might be confusing for code readers why we're not simply adding the types.Transaction we already have. Code changes summary: - txpool.Transaction removed and all uses replaced by types.Transaction again - blobpool now stores types.Transaction instead of defining its own blobTx format for storage - the blobpool limbo now stores types.Transaction instead of storing only the blobs - checks to validate the presence/absence of the blob sidecar added in certain critical places

core/types: support for optional blob sidecar in BlobTx (#27841) This PR removes the newly added txpool.Transaction wrapper type, and instead adds a way of keeping the blob sidecar within types.Transaction. It's better this way because most code in go-ethereum does not care about blob transactions, and probably never will. This will start mattering especially on the client side of RPC, where all APIs are based on types.Transaction. Users need to be able to use the same signing flows they already have. However, since blobs are only allowed in some places but not others, we will now need to add checks to avoid creating invalid blocks. I'm still trying to figure out the best place to do some of these. The way I have it currently is as follows: - In block validation (import), txs are verified not to have a blob sidecar. - In miner, we strip off the sidecar when committing the transaction into the block. - In TxPool validation, txs must have a sidecar to be added into the blobpool. - Note there is a special case here: when transactions are re-added because of a chain reorg, we cannot use the transactions gathered from the old chain blocks as-is, because they will be missing their blobs. This was previously handled by storing the blobs into the 'blobpool limbo'. The code has now changed to store the full transaction in the limbo instead, but it might be confusing for code readers why we're not simply adding the types.Transaction we already have. Code changes summary: - txpool.Transaction removed and all uses replaced by types.Transaction again - blobpool now stores types.Transaction instead of defining its own blobTx format for storage - the blobpool limbo now stores types.Transaction instead of storing only the blobs - checks to validate the presence/absence of the blob sidecar added in certain critical places
