      Testsuite: use ignore_stderr/stdout instead of ignore_output · 1084d375
      thomie authored
      The problem with ignore_output is that it hides errors for WAY=ghci.
      GHCi always returns with exit code 0 (unless it is broken itself).
      
      For example: ghci015 must have been failing with compile errors for
      years, but we didn't notice because all output was ignored.
      
      Therefore, replace all uses of ignore_output with either ignore_stderr
      or ignore_stdout. In some cases I opted for adding the expected output.
      
      Update submodule hpc and stm.

      Fix bytecode gen to deal with rep-polymorphism · 0f1e315b
      Simon Peyton Jones authored
      When faced runtime-rep-polymorphic code from a pattern-synonym
      matcher, the bytecode generator was treating the result as lifted,
      which it isn't.  The fix is just to treat those rep-polymorphic
      continuations like unlifted types, and add a dummy arg.
      
      Trac #12007 is a case in point.

      Greater customization of GHCi prompt · 533037cc
      niksaz authored
      This patch is trying to redesign the :set prompt option to take not a
      String but a Haskell function, like [String] -> Int -> IO String, where
      [String] is the list of the names of the currently loaded modules and
      Int is the line number. Currently you may set prompt function with
      **:set promt-function [String] -> Int -> IO String** option and old
      version is also available - :set prompt String.
      
      So, it looks like I've almost completed this patch:
      
      1) Now we have a lot of escape sequences - 13 to be exact. Most of them
         are similar to bash prompt escape sequences. Thus they are quite handy.
      
      2) We may use the special escape sequence to call shell functions, for
         example "%call(ls -l -a)".
      
      3) We may use :set prompt-function to set PFunction to handle prompt.
         It is just [String] -> Int -> IO String.

      In particular, this allows correct tracking of specified/invisible
      for variables in Haskell98 data constructors and in pattern synonyms.
      GADT-syntax constructors are harder, and are left until #11721.

      Reject import declaration with semicolon in GHCi · a84c21eb
      Rik Steenkamp authored
      Now GHCi rejects input containing an import declaration and semicolon,
      and prints an appropriate error message. Before, the stuff after an
      import declaration and semicolon got ignored (most of the time), without
      telling the user about it. As the default behaviour of GHCi is to reject
      multiple commands in a single input, we extend this behaviour to import
      commands.
      
      This patch fixes #10663.

      Identifiers starting with an underscore are now always parsed as type
      variables.  When the NamedWildCards extension is enabled, the renamer
      replaces those variables with named wildcards.
      
      An additional NameSet nwcs is added to LocalRdrEnv. It's used to keep
      names of the type variables that should be replaced with wildcards.
      
      While renaming HsForAllTy, when a name is explicitly bound it is removed
      from the nwcs NameSet. As a result, the renamer doesn't replace them in
      the quantifier body. (Trac #11098)

      Remote GHCi, -fexternal-interpreter · 4905b83a
      Simon Marlow authored
      Summary:
      (Apologies for the size of this patch, I couldn't make a smaller one
      that was validate-clean and also made sense independently)
      
      (Some of this code is derived from GHCJS.)
      
      This commit adds support for running interpreted code (for GHCi and
      TemplateHaskell) in a separate process.  The functionality is
      experimental, so for now it is off by default and enabled by the flag
      -fexternal-interpreter.
      
      Reaosns we want this:
      
      * compiling Template Haskell code with -prof does not require
        building the code without -prof first
      
      * when GHC itself is profiled, it can interpret unprofiled code, and
        the same applies to dynamic linking.  We would no longer need to
        force -dynamic-too with TemplateHaskell, and we can load ordinary
        objects into a dynamically-linked GHCi (and vice versa).
      
      * An unprofiled GHCi can load and run profiled code, which means it
        can use the stack-trace functionality provided by profiling without
        taking the performance hit on the compiler that profiling would
        entail.
      
      Amongst other things; see
      https://ghc.haskell.org/trac/ghc/wiki/RemoteGHCi for more details.
      
      Notes on the implementation are in Note [Remote GHCi] in the new
      module compiler/ghci/GHCi.hs.  It probably needs more documenting,
      feel free to suggest things I could elaborate on.
      
      Things that are not currently implemented for -fexternal-interpreter:
      
      * The GHCi debugger
      * :set prog, :set args in GHCi
      * `recover` in Template Haskell
      * Redirecting stdin/stdout for the external process
      
      These are all doable, I just wanted to get to a working validate-clean
      patch first.
      
      I also haven't done any benchmarking yet.  I expect there to be slight hit
      to link times for byte code and some penalty due to having to
      serialize/deserialize TH syntax, but I don't expect it to be a serious
      problem.  There's also lots of low-hanging fruit in the byte code
      generator/linker that we could exploit to speed things up.
      
      Test Plan:
      * validate
      * I've run parts of the test suite with
      EXTRA_HC_OPTS=-fexternal-interpreter, notably tests/ghci and tests/th.
      There are a few failures due to the things not currently implemented
      (see above).

      Make GHCi & TH work when the compiler is built with -prof · ce1f1607
      Simon Marlow authored
      Summary:
      Amazingly, there were zero changes to the byte code generator and very
      few changes to the interpreter - mainly because we've used good
      abstractions that hide the differences between profiling and
      non-profiling.  So that bit was pleasantly straightforward, but there
      were a pile of other wibbles to get the whole test suite through.
      
      Note that a compiler built with -prof is now like one built with
      -dynamic, in that to use TH you have to build the code the same way.
      For dynamic, we automatically enable -dynamic-too when TH is required,
      but we don't have anything equivalent for profiling, so you have to
      explicitly use -prof when building code that uses TH with a profiled
      compiler.  For this reason Cabal won't work with TH.  We don't expect
      to ship a profiled compiler, so I think that's OK.

      Update Cabal to HEAD, IPID renamed to Component ID. · 5b0191f7
      Edward Z. Yang authored
      
      
      This commit contains a Cabal submodule update which unifies installed
      package IDs and package keys under a single notion, a Component ID.
      We update GHC to keep follow this unification.  However, this commit
      does NOT rename installed package ID to component ID and package key to
      unit ID; the plan is to do that in a companion commit.
      
          - Compiler info now has "Requires unified installed package IDs"
      
          - 'exposed' is now expected to contain unit keys, not IPIDs.
      
          - Shadowing is no more.  We now just have a very simple strategy
            to deal with duplicate unit keys in combined package databases:
            if their ABIs are the same, use the latest one; otherwise error.
            Package databases maintain the invariant that there can only
            be one entry of a unit ID.

      * extra_clean argument should be a list
        Add an assert to prevent regressions.
      
      * properly clean package conf direcories
        They are directories now, which was causing problems.
      
      * properly clean write_interface_* tests
        We were getting these errors:
      
        [Errno 21] Is a directory: './driver/write_interface_oneshot'
        [Errno 39] Directory not empty: './driver/write_interface_oneshot'
        [Errno 21] Is a directory: './driver/write_interface_make'
        [Errno 39] Directory not empty: './driver/write_interface_make'
      
      * outputdir() is better than -outputdir, as it knows how to (pre)clean
        itself.
