      Rename getErrorMessages and getMessages function in parser code · 56eb57a6
      Alfredo Di Napoli authored
      This commit renames the `getErrorMessages` and
      `getMessages` function in the parser code to `getPsErrorMessages` and
      `getPsMessages`, to avoid import conflicts, as we have already
      `getErrorMessages` and `getMessages` defined in `GHC.Types.Error`.
      Fixes #19920.
      Update haddock submodule

      driver: Convert runPipeline to use a free monad · 421beb3f
      Matthew Pickering authored and  Marge Bot's avatar Marge Bot committed
      This patch converts the runPipeline function to be implemented in terms
      of a free monad rather than the previous CompPipeline.
      The advantages of this are three-fold:
      1. Different parts of the pipeline can return different results, the
      limits of runPipeline were being pushed already by !5555, this opens up
      futher fine-grainedism of the pipeline.
      2. The same mechanism can be extended to build-plan at the module level
      so the whole build plan can be expressed in terms of one computation
      which can then be treated uniformly.
      3. The pipeline monad can now be interpreted in different ways, for
      example, you may want to interpret the `TPhase` action into the monad
      for your own build system (such as shake). That bit will probably
      require a bit more work, but this is a step in the right directin.
      There are a few more modules containing useful functions for interacting
      with the pipelines.
      * GHC.Driver.Pipeline: Functions for building pipelines at a high-level
      * GHC.Driver.Pipeline.Execute: Functions for providing the default
      interpretation of TPhase, in terms of normal IO.
      * GHC.Driver.Pipeline.Phases: The home for TPhase, the typed phase data
      type which dictates what the phases are.
      * GHC.Driver.Pipeline.Monad: Definitions to do with the TPipelineClass
      and MonadUse class.
      Hooks consumers may notice the type of the `phaseHook` has got
      slightly more restrictive, you can now no longer control the
      continuation of the pipeline by returning the next phase to execute but
      only override individual phases. If this is a problem then please open
      an issue and we will work out a solution.

      Implement improved "get executable path" query · 4b4c5e43
      Fraser Tweedale authored and  Marge Bot's avatar Marge Bot committed
      System.Environment.getExecutablePath has some problems:
      - Some system-specific implementations throw an exception in some
        scenarios, e.g. when the executable file has been deleted
      - The Linux implementation succeeds but returns an invalid FilePath
        when the file has been deleted.
      - The fallback implementation returns argv[0] which is not
        necessarily an absolute path, and is subject to manipulation.
      - The documentation does not explain any of this.
      Breaking the getExecutablePath API or changing its behaviour is not
      an appealing direction.  So we will provide a new API.
      There are two facets to the problem of querying the executable path:
      1. Does the platform provide a reliable way to do it?  This is
         statically known.
      2. If so, is there a valid answer, and what is it?  This may vary,
         even over the runtime of a single process.
      Accordingly, the type of the new mechanism is:
        Maybe (IO (Maybe FilePath))
      This commit implements this mechanism, defining the query action for
      FreeBSD, Linux, macOS and Windows.

      Arity: Handle shadowing properly · 9b1d9cbf
      Sebastian Graf authored and  Marge Bot's avatar Marge Bot committed
      In #20070, we noticed that `findRhsArity` copes badly with shadowing.
      A simple function like `g_123 x_123 = x_123`, where the labmda binder shadows,
      already regressed badly.
      Indeed, the whole `arityType` function wasn't thinking about shadowing *at all*.
      I rectified that and established the invariant that `ae_join` and `am_sigs`
      should always be disjoint. That entails deleting bindings from `ae_join`
      whenever we add something to `am_sigs` and vice versa, which would otherwise be
      a bug in the making.
      That *should* fix (but I don't want to close it) #20070.
