Test.Util.ChainDB

Synopsis

Documentation

Minimal set of arguments for creating a ChainDB instance for testing purposes.

Constructors

Fields

mcdbTopLevelConfig ∷ TopLevelConfig blk
mcdbChunkInfo ∷ ChunkInfo
Specifies the layout of the ImmutableDB on disk.
mcdbInitLedger ∷ ExtLedgerState blk ValuesMK
The initial ledger state.
mcdbRegistry ∷ ResourceRegistry m
Keeps track of non-lexically scoped resources.
mcdbNodeDBs ∷ NodeDBs (StrictTMVar m MockFS)
File systems underlying the immutable, volatile and ledger databases. Would be useful to default this to StrictTMVar's containing empty MockFS's.

A vector with an element for each database of a node

The db type parameter is instantiated by this module at types for mock filesystems; either the MockFS type or reference cells thereof.

Creates a default set of of arguments for ChainDB tests.

Utility function to get a default chunk info in case we have EraParams available.
