Module solana_runtime::snapshot_utils
source · [−]Structs
Information about a bank snapshot. Namely the slot of the bank, the path to the snapshot, and the type of the snapshot.
Enums
The different archive formats used for snapshots
Bank snapshots traditionally had their accounts hash calculated prior to serialization. Since the hash calculation takes a long time, an optimization has been put in to offload the accounts hash calculation. The bank serialization format has not changed, so we need another way to identify if a bank snapshot contains the calculated accounts hash or not.
allow tests to specify what happened to the serialized format
Constants
Functions
Serialize a bank to a snapshot
Make a snapshot archive out of the snapshot package
Utility for parsing out bank specific information from a snapshot archive. This utility can be used to parse out bank specific information like the leader schedule, epoch schedule, etc.
Rebuild bank from snapshot archives. This function searches full_snapshot_archives_dir and incremental_snapshot_archives_dir for the
highest full snapshot and highest corresponding incremental snapshot, then rebuilds the bank.
Rebuild bank from snapshot archives. Handles either just a full snapshot, or both a full snapshot and an incremental snapshot.
Convenience function to create a full snapshot archive out of any Bank, regardless of state. The Bank will be frozen during the process. This is only called from ledger-tool or tests. Warping is a special case as well.
Convenience function to create an incremental snapshot archive out of any Bank, regardless of state. The Bank will be frozen during the process. This is only called from ledger-tool or tests. Warping is a special case as well.
Build the full snapshot archive path from its components: the snapshot archives directory, the snapshot slot, the accounts hash, and the archive format.
Build the incremental snapshot archive path from its components: the snapshot archives directory, the snapshot base slot, the snapshot slot, the accounts hash, and the archive format.
Get the bank snapshots in a directory
Get the bank snapshots in a directory
Get the bank snapshots in a directory
Get a list of the full snapshot archives from a directory
Get the bank snapshot with the highest slot in a directory
Get the bank snapshot with the highest slot in a directory
Get the path (and metadata) for the full snapshot archive with the highest slot in a directory
Get the highest slot of the full snapshot archives in a directory
Get the path for the incremental snapshot archive with the highest slot, for a given full snapshot slot, in a directory
Get the highest slot of the incremental snapshot archives in a directory, for a given full snapshot slot
Get a list of the incremental snapshot archives from a directory
Helper function to hold shared code to package, process, and archive full snapshots
Helper function to hold shared code to package, process, and archive incremental snapshots
Get the &str from a &Path
Remove outdated bank snapshots
Remove the snapshot directory for this slot
If the validator halts in the middle of archive_snapshot_package(), the temporary staging
directory won’t be cleaned up. Call this function to clean them up.
Gather the necessary elements for a snapshot of the given root_bank.
