Different types of specifications

There are different types or "flavours" for a specification, depending on its lifecycle. The main goal is always the same, i.e. refining the Haskell types and produce a final statement (i.e. safe or unsafe) about the input program. In order to do so, a specification is transformed in the way described by this picture:

    +---------------+                                +-------------------+
    |   BareSpec    |                                |                   |  checked by liquid/liquidOne
    |               |                    ------------|    TargetSpec     |----------------------------- ..
    |(input module) |                   /            |                   |
    +---------------+  makeTargetSpec  /             +-------------------+
           +         -----------------/
    +---------------+                 \              +-------------------+
    | {LiftedSpec}  |                  \             |                   |    serialised on disk
    |               |                   -------------|    LiftedSpec     |----------------------------- ..
    |(dependencies) |                                |                   |
    +---------------+                                +-------------------+
          ^                                                    |
          |                   used-as                          |
          +----------------------------------------------------+

More specifically, we distinguish:

BareSpec - is the specification obtained by parsing the Liquid annotations of the input Haskell file. It typically contains information about the associated input Haskell module, with the exceptions of assumptions that can refer to functions defined in other modules.
LiftedSpec - is the specification we obtain by "lifting" the BareSpec. Most importantly, a LiftedSpec gets serialised on disk and becomes a dependency for the verification of other BareSpecs.

Lifting in this context consist of:

Perform name-resolution (e.g. make all the relevant GHC's Vars qualified, resolve GHC's Names, etc);
Strip the final LiftedSpec with information which are relevant (read: local) to just the input BareSpec. An example would be local signatures, used to annotate internal, auxiliary functions within a Module;
Strip termination checks, which are required (if specified) for a BareSpec but not for the LiftedSpec.

TargetSpec - is the specification we actually use for refinement, and is conceptually an "augmented" BareSpec. You can create a TargetSpec by calling makeTargetSpec.

In order to produce these spec types we have to gather information about the module being compiled by using the GHC API and retain enough context of the compiled Module in order to be able to construct the types introduced aboves. The rest of this module introduced also these intermediate structures.

The following is the overall type for specifications obtained from parsing the target source and dependent libraries. IMPORTANT: A TargetInfo is what is checked by LH itself and it NEVER contains the LiftedSpec, because the checking happens only on the BareSpec of the target module.

data TargetInfo Source #

Constructors

Gathering information about a module

data TargetSrc Source #

The TargetSrc type is a collection of all the things we know about a module being currently checked. It include things like the name of the module, the list of CoreBinds, the TyCons declared in this module (that includes TyCons for classes), typeclass instances and so and so forth. It might be consider a sort of ModGuts embellished with LH-specific information (for example, giDefVars are populated with datacons from the module plus the let vars derived from the A-normalisation).

TargetSpec

data TargetSpec Source #

A TargetSpec is what we actually check via LiquidHaskell. It is created as part of mkTargetSpec alongside the LiftedSpec. It shares a similar structure with a BareSpec, but manipulates and transforms the data in preparation to the checking process.

BareSpec

type BareSpec = Spec Symbol BareType Source #

A BareSpec is the spec we derive by parsing the Liquid Haskell annotations of a single file. As such, it contains things which are relevant for validation and lifting; it contains things like the pragmas the user defined, the termination condition (if termination-checking is enabled) and so on and so forth. Crucially, as a BareSpec is still subject to "preflight checks", it may contain duplicates (e.g. duplicate measures, duplicate type declarations etc.) and therefore most of the fields for a BareSpec are lists, so that we can report these errors to the end user: it would be an error to silently ignore the duplication and leave the duplicate resolution to whichever Eq instance is implemented for the relevant field.

Also, a BareSpec has not yet been subject to name resolution, so it may refer to undefined or out-of-scope entities.

type BareSpecLHName = Spec LHName BareTypeLHName Source #

type BareSpecParsed = Spec LocSymbol BareTypeParsed Source #

LiftedSpec

data LiftedSpec Source #

A LiftedSpec is derived from an input BareSpec and a set of its dependencies. The general motivations for lifting a spec are (a) name resolution, (b) the fact that some info is only relevant for checking the body of functions but does not need to be exported, e.g. termination measures, or the fact that a type signature was assumed. A LiftedSpec is what we serialise on disk and what the clients should will be using.

What we do not have compared to a BareSpec:

The reflSigs, they are now just "normal" signatures;
The lazy, we don't do termination checking in lifted specs;
The reflects, the reflection has already happened at this point;
The hmeas, we have already turned these into measures at this point;
The inlines, ditto as hmeas;
The ignores, ditto as hmeas;
The pragmas, we can't make any use of this information for lifted specs;
The termexprs, we don't do termination checking in lifted specs;

Apart from less fields, a LiftedSpec replaces all instances of lists with sets, to enforce duplicate detection and removal on what we serialise on disk.

Constructors

Fields

liftedMeasures :: HashMap Symbol (MeasureV LHName LocBareTypeLHName (Located LHName))
Measures (a.k.a. user-defined properties for ADTs)
The key of the HashMap is the unqualified name of the measure. Constructing such a map discards preceding measures with the same name as later measures, which makes possible to predict which of a few conflicting measures will be exported.
Tested in MeasureOverlapC.hs
liftedExpSigs :: HashSet (LHName, Sort)
Exported logic symbols originated from reflecting functions
liftedPrivateReflects :: HashSet LocSymbol
Private functions that have been reflected
liftedAsmSigs :: HashSet (Located LHName, LocBareTypeLHName)
Assumed (unchecked) types; including reflected signatures
liftedSigs :: HashSet (Located LHName, LocBareTypeLHName)
Asserted spec signatures
liftedInvariants :: HashSet (Maybe LocSymbol, LocBareTypeLHName)
Data type invariants; the Maybe is the generating measure
liftedIaliases :: HashSet (LocBareTypeLHName, LocBareTypeLHName)
Data type invariants to be checked
liftedDataDecls :: HashSet DataDeclLHName
Predicated data definitions
liftedNewtyDecls :: HashSet DataDeclLHName

liftedAliases :: HashSet (Located (RTAlias Symbol BareTypeLHName))
RefType aliases
liftedEaliases :: HashSet (Located (RTAlias Symbol (ExprV LHName)))

Measures attached to a type-class
Imitates the arrangement for liftedMeasures
