Unison.Codebase.SqliteCodebase.Operations
Description
This module contains sqlite-specific operations on high-level "parser-typechecker" types all in the Transaction monad.
The Codebase record-of-functions wraps this functionality, and runs each transaction to IO, so that the operations'
are unified with non-sqlite operations in the Codebase interface, like appendReflog.

hashLength :: Transaction Int Source #
The number of base32 characters needed to distinguish any two references in the codebase.
branchHashLength :: Transaction Int Source #
The number of base32 characters needed to distinguish any two branch in the codebase.
defnReferencesByPrefix :: ObjectType -> ShortHash -> Transaction (Set Id) Source #
termReferencesByPrefix :: ShortHash -> Transaction (Set Id) Source #
typeReferencesByPrefix :: ShortHash -> Transaction (Set Id) Source #
Get the set of type declarations whose hash matches the given prefix.
Arguments

| -> ShortHash | |
| -> Transaction (Set Id) |
causalHashesByPrefix :: ShortCausalHash -> Transaction (Set CausalHash) Source #
Get the set of branches whose hash matches the given prefix.
termExists :: Hash -> Transaction Bool Source #
declExists :: Hash -> Transaction Bool Source #
before :: CausalHash -> CausalHash -> Transaction Bool Source #
makeCachedTransaction :: Ord a => Cache a b -> (a -> Transaction b) -> a -> Transaction b Source #
Given a transaction, return a transaction that first checks a given semispace cache.
The transaction should probably be read-only, as we (of course) don't hit SQLite on a cache hit.
makeMaybeCachedTransaction :: Ord a => Cache a b -> (a -> Transaction (Maybe b)) -> a -> Transaction (Maybe b) Source #
Like makeCachedTransaction, but for when the transaction returns a Maybe; only cache the Justs.
insertProjectAndBranch :: ProjectName -> ProjectBranchName -> CausalHashId -> Transaction (Project, ProjectBranchRow) Source #
Creates a project by name if one doesn't already exist, creates a branch in that project, then returns the project and branch ids. Fails if a branch by that name already exists in the project.
emptyCausalHash :: Transaction (CausalHash, CausalHashId) Source #
Often we need to assign something to an empty causal, this ensures the empty causal exists in the codebase and returns its hash.
