ReadHeaderRange returns the rlp-encoded headers, starting at 'number', and going backwards towards genesis. This method assumes that the caller already has placed a cap on count, to prevent DoS issues. Since this method operates in head-towards-genesis mode, it will return an empty slice in case the head ('number') is missing. Hence, the caller must ensure that the head ('number') argument is actually an existing header.
N.B: Since the input is a number, as opposed to a hash, it's implicit that this method only operates on canon headers.

Types ¶
type Freezer ¶
type Freezer struct {
// contains filtered or unexported fields
}
Freezer is a memory mapped append-only database to store immutable ordered data into flat files:
- The append-only nature ensures that disk writes are minimized.
- The memory mapping ensures we can max out system memory for caching without reserving it for go-meranium. This would also reduce the memory requirements of Geth, and thus also GC overhead.
func NewFreezer ¶
func NewFreezer(datadir string, namespace string, readonly bool, maxTableSize uint32, tables map[string]bool) (*Freezer, error)
NewFreezer creates a freezer instance for maintaining immutable ordered data according to the given parameters.
The 'tables' argument defines the data tables. If the value of a map entry is true, snappy compression is disabled for the table.
func (*Freezer) Ancient ¶
Ancient retrieves an ancient binary blob from the append-only immutable files.
func (*Freezer) AncientRange ¶
AncientRange retrieves multiple items in sequence, starting from the index 'start'. It will return
- at most 'max' items,
- at least 1 item (even if exceeding the maxByteSize), but will otherwise return as many items as fit into maxByteSize.
func (*Freezer) AncientSize ¶
AncientSize returns the ancient size of the specified category.
func (*Freezer) HasAncient ¶
HasAncient returns an indicator whether the specified ancient data exists in the freezer.
func (*Freezer) MigrateTable ¶
MigrateTable processes the entries in a given table in sequence converting them to a new format if they're of an old format.
func (*Freezer) ModifyAncients ¶
ModifyAncients runs the given write operation.
func (*Freezer) ReadAncients ¶
func (f *Freezer) ReadAncients(fn func(ethdb.AncientReaderOp) error) (err error)
ReadAncients runs the given read operation while ensuring that no writes take place on the underlying freezer.
func (*Freezer) TruncateHead ¶
TruncateHead discards any recent data above the provided threshold number.
func (*Freezer) TruncateTail ¶
TruncateTail discards any recent data below the provided threshold number.
type KeyLengthIterator ¶
KeyLengthIterator is a wrapper for a database iterator that ensures only key-value pairs with a specific key length will be returned.
func (*KeyLengthIterator) Next ¶
func (it *KeyLengthIterator) Next() bool
type LegacyTxLookupEntry ¶
LegacyTxLookupEntry is the legacy TxLookupEntry definition with some unnecessary fields.
type NumberHash ¶
func ReadAllHashesInRange ¶
func ReadAllHashesInRange(db ethdb.Iteratee, first, last uint64) []*NumberHash
ReadAllHashesInRange retrieves all the hashes assigned to blocks at certain heights, both canonical and reorged forks included. This method considers both limits to be _inclusive_.
