cabal-install users should note that cabal-install-3.0 or later is required

but this seems wrong or have I done something wrong?

Omer, Ben
There's a little cluster of tickets that it'd be really good to nail.

  *   !1381/#16893: inline unsafeCoerce# in CorePrep
  *   #17041: coercion safety in STG Lint
  *   !1552: tidy up linting on unsafe coercions
  *   #16964: definition of Int#
  *   #17026: definition of IntRep
They are all somehow tied up together.  Can we kill them off together, soon?  I have left comments...

Thanks Herbert.

That might have been true at that moment, but it's not true now -- I just checked.  Let's see if it reoccurs

Omer, I think you have this paged in more than I (not to mention that I am still living out of a tent at the moment). Can you comment here?

Thanks.  I tried `git submodule init` and `git submodule update`, but not `git submodule sync`.

Anyway it seems to happen just once in each tree so I can probably live with it.

Subject: Re: Submodule woe

This doesn't appear to happen in a fresh clone.

As I wasn't able to reproduce, it's a shot in the dark. But `git submodule sync && git submodule update` might solve the issue without needed to clone GHC afresh.

Hi all,

 > !1381/#16893: inline unsafeCoerce# in CorePrep

The problem with !1381 is that it reveals a coercion accepted by CoreLint but
rejected by an assertion later in the compilation. The coercion casts an Int# to
Int64#, which is fine on a 64-bit system. One way to fix this is by fixing
#17026, but as explained in the issue it's too much work and it'll either
require huge amount of work (if we implement some kind of Type/TyCon caching) or
make everything slower (if we make top-level intPrimTy/intPrimTyCon which are
currently constants, functions).

 > #17041: coercion safety in STG Lint

This basically asks for a type checker that works on PrimReps instead of Types.
I was too busy with #9718/!1304 and #17088 so couldn't make progress here.
Perhaps I can work on this at MuniHac.

 > !1552: tidy up linting on unsafe coercions

I'll address your comments and test this more. My main concern (and the reason
why I added "DO NOT MERGE") was that I wasn't 100% sure that this change is
sound (though I don't remember what I was concerned about specifically). I'll
try to test this more on my desktop (where I can more efficiently make release
builds and test) when I'm back home.

 > #16964: definition of Int#

The part related to GHC internals is moved to #17026. Regarding definition of
Int#, I'm not sure what to do about this,

 > #17026: definition of IntRep

Simon argues that if we keep Int and Int# distinct types (rather than synonyms
to Int32/Int64 and Int32#/Int64# depending on platform word size, this is
discussed in #16964) then we should keep RuntimeReps for them distinct too.
I think this is mostly fine but a problem with this that blocked !1381 is IntRep
and Int64Rep are not equal (according to the Eq instance) on a 64-bit system so
a simple code that checks whether two types are represented the same fails.

If we keep IntRep/WordRep then I think we should remove the Eq instance of
PrimRep and and provide a `primRepEq :: PlatformWordSize -> PrimRep -> PrimRep
-> Eq` for checking whether types are represented the same on the target
platform (or maybe name it `primRepCoercible`).


So in summary; I think I'll make progress in this order:

- Read the changes in !1552, test it more.
     - If merged then !1381 will be unblocked, merge it.
- Remove Eq instance of PrimRep, implement primRepEq (or primRepCoercible) that
   takes target platform size as argument. Use this in coercion checks.
     - This also unblocks !1381, merge it
- Implement type checker in StgLint that works on PrimReps (instead of on
   actual types).

I'm not sure about how to proceed in #16964. I'm inclined to just document the
status quo more accurately, but apparently there's also a MR that's supposed to
improve/fix it (!1102), though I'm having trouble seeing how it is even related.

Subject: New implementation for `ImpredicativeTypes`
Message-ID: <CAHnFXOumYR+nKkBv6B6_zHVA2D=b9kZVyZ3vTTu87R07h90YuA@mail.gmail.com>

Hi all,
As I mentioned some time ago, we have been busy working on a new
implementation of `ImpredicativeTypes` for GHC. I am very thankful to
everybody who back then sent us examples of impredicativity which would be
nice to support, as far as we know this branch supports all of them! :)

If you want to try it, at
https://gitlab.haskell.org/trupill/ghc/commit/a3f95a0fe0f647702fd7225fa719a8062a4cc0a5/pipelines?ref=quick-look-build
you can find the result of the pipeline, which includes builds for several
platforms (click on the "Artifacts" button, the one which looks like a
cloud, to get them). The code is being developed at
https://gitlab.haskell.org/trupill/ghc.

Any code should run *unchanged* except for some eta-expansion required for
some specific usage patterns of higher-rank types. Please don't hesitate to
ask any questions or clarifications about it. A merge request for tracking
this can be found at https://gitlab.haskell.org/ghc/ghc/merge_requests/1659

Kind regards,
Alejandro

You successfully persuaded me, in #17026, that getting rid of Int and IntRep in a platform-dependent way is very awkward to implement.

My proposal, made in #17026 is:

* Keep Int# distinct from Int32#, Int64#
* Keep IntRep distinct from Int32Rep, Int64Rep.
* Have primops to convert between Ints of various widths. 
  (Need to lay out exactly what these are.)

* And make the core-to-STG (only) implement some of these
  primops as no-ops, depending on the architecture; 
  e.g. Int# -> Int64# is a no-op on a 64 bit machine.

  So STG would "know" that Int# and Int64# are the same.
  I say STG because the unarise pass needs to know the
  width of each type for implementing sum types, I think.

* So yes, some tests in the STG and Cmm part would need
  platform information.

Does that make sense?  If so that would unblock !1381.

Simon

I didn't say anything when you were requesting use cases, so I have no
right to complain, but I'm still a little disappointed that this doesn't
fix my (admittedly very minor) issue:
https://www.reddit.com/r/haskell/comments/3am0qa/existentials_and_the_heterogenous_list_fallacy/csdwlp2/?context=8&depth=9

For those who don't want to click on the reddit link: I would like to be
able to write something like map show ([1, 'a', "b"] :: [forall a. Show a
=> a]), and have it work.

I’m confused.   Char does not have the type (forall a. Show a =>a), so our example is iill-typed in System F, never mind about type inference.  Perhaps there’s a typo?   I think you may have ment
               exists a. Show a => a
which doesn’t exist in Haskell.  You can write existentials with a data type

data Showable where
   S :: forall a. Show a => a -> Showable

Then
               map show [S 1, S ‘a’, S “b”]
works fine today (without our new stuff), provided you say

               instance Show Showable where
                 show (S x) = show x

Our new system can only type programs that can be written in System F.   (The tricky bit is inferring the impredicative instantiations.)

Hi Simon,

You're exactly right, of course. My example is confusing, so let me see if
I can clarify.

What I want in the ideal is map show [1, 'a', "b"]. That is, minimal
syntactic overhead to mapping a function over multiple values of distinct
types that results in a homogeneous list. As the reddit thread points out,
there are workarounds involving TH or wrapping each element in a
constructor or using bespoke operators, but when it comes down to it, none
of them actually allows me to say what I *mean*; the TH one is closest, but
I reach for TH only in times of desperation.

I had thought that one of the things preventing this was lack of
impredicative instantiation, but now I'm not sure. Suppose Haskell *did*
have existentials; would map show @(exists a. Show a => a) [1, 'a', "b"]
work in current Haskell and/or in quick-look?

Tangentially, do you have a reference for what difficulties arise in adding
existentials to Haskell? I have a feeling that it would make working with
GADTs more ergonomic.

I got there by doing,
```
  cabal v2-install --installdir=~/.cabal/bin alex
  cabal v2-install --installdir=~/.cabal/bin happy
```
and things seemed to be going smoothly enough after that.

Hello Alex,

the issue with your example is not the mapping of `show` but the list
`[1, 'a', "b"]`.  It is not well typed simply because of how lists are
defined.   Remember that `[1, 'a', "b"]` is not really special---it is
just syntactic sugar for `1 : 'a' : "b" : []` and the type of `(:)`
requires the elements to have the same type.

Of course, in principle, one could define a different list type that
allowed values of arbitrary types to be stored in it (e.g., the
example list would be just of type `List`).
The issue is that you can't really use the elements of such a list as
you wouldn't know what type they have.

Yet another option is to define a list type where the "cons" operation
remembers the types of the elements in the type of the constructed
list---at this point the lists become more like tuples (e.g., the
example would be of type `List [Int,Char,String]`).   This is
possible, but then them `map` function would have an interesting
type...

I'd be happy to answer more questions but I don't want to side-track
the thread as all this is quite orthogonal to impredicative types.

Hi Alex,
Also de-railing the conversation, the Utrecht Haskell Compiler supports
existential types in addition to universally-quantified ones. The work on
Atze Dijkstra (among others) describes some of the problems and possible
solutions to inference:
- His PhD thesis [https://dspace.library.uu.nl/handle/1874/7352] describes
existentials in Section 8.
- Their paper "A Lazy Language Needs a Lazy Type System" [
https://dspace.library.uu.nl/handle/1874/346316] proposes treating
existential types as "polymorphic contexts".

Going back to impredicativity, adding existential types would only
complicate inference more, since there are more types to choose from while
instantiating. But the delta would not be that large, since once a type
constructor guards a type, everything inside of it should be equal, and
checking equality of existential types is as hard as checking for universal
types.

Alejandro

Iavor,

Alex’s example can be well-typed if we allow first-class existentials:

  [1, ‘a’, “b”] :: [exists a. Show a => a]

This has nothing to do with the definition of lists. I believe the confusion was between existential types and impredicative types, as Simon has pointed out.

Why would you infer this type as opposed to `[exists a. a]`?

No, I don’t expect the compiler to infer existential quantification, just like it doesn’t infer higher-rank universal quantification. However, I believe we could check terms against user-written types that contain existentials.

I submitted !1667 which fixes the coercion checks outside of CorePrep. The
coercion checks are now done the same way as in CorePrep (as explained in Note
[Bad unsafe coercion]) and they take the platform word size into account. This
unblocks !1381.

Thanks for everybody's responses. I figured out that the following

cabal-install users should note that cabal-install-3.0 or later is required
for use with GHC 8.8.


means  I should have cabal-install-3.0 before installing 8.8.1. Once I did
that everything is fine.

Maybe configure should give an error if the user does not
have cabal-install-3.0?

Thanks
George

Hi all,

Today I picked up an old worktree that hadn't seen much action for
a couple months and tried to get the developer environment running
again. I believe I ran into issues in Cabal, Hadrian, and/or
ghc.nix that may be interesting to some.

I wrote up the event log here: https://gitlab.haskell.org/snippets/1475

It all ends well; I am now successfully running hadrian/ghci.sh via
ghcid within the ghc.nix shell once again. :)

-Bryan

P.S.: I believe Shayne recommended using the devel2 build flavor
for most kinds of work. At Zurihac I ended up rebuilding the whole
tree a couple times because that flavor isn't the default (once for
Make, once for Hadrian). I will not in any way suggest changing the
defaults, but perhaps some script or other could prompt the user to
make their choice, if they haven't already?

Suppose Haskell did have existentials;

Yes, I think that's an interesting thing to work on!  I'm not sure what the implications would be.  At very least we'd need to extend System FC (GHC's intermediate language) with existential types and the corresponding pack and unpack syntactic forms.

I don't know of any work studying that question specifically, but others may have pointers.

Subject: Re: New implementation for `ImpredicativeTypes`

Hi Simon,

You're exactly right, of course. My example is confusing, so let me see if I can clarify.

What I want in the ideal is map show [1, 'a', "b"]. That is, minimal syntactic overhead to mapping a function over multiple values of distinct types that results in a homogeneous list. As the reddit thread points out, there are workarounds involving TH or wrapping each element in a constructor or using bespoke operators, but when it comes down to it, none of them actually allows me to say what I mean; the TH one is closest, but I reach for TH only in times of desperation.

I had thought that one of the things preventing this was lack of impredicative instantiation, but now I'm not sure. Suppose Haskell did have existentials; would map show @(exists a. Show a => a) [1, 'a', "b"] work in current Haskell and/or in quick-look?

Tangentially, do you have a reference for what difficulties arise in adding existentials to Haskell? I have a feeling that it would make working with GADTs more ergonomic.

I'm confused.   Char does not have the type (forall a. Show a =>a), so our example is iill-typed in System F, never mind about type inference.  Perhaps there's a typo?   I think you may have ment
               exists a. Show a => a
which doesn't exist in Haskell.  You can write existentials with a data type

data Showable where
   S :: forall a. Show a => a -> Showable

Then
               map show [S 1, S 'a', S "b"]
works fine today (without our new stuff), provided you say

               instance Show Showable where
                 show (S x) = show x

Our new system can only type programs that can be written in System F.   (The tricky bit is inferring the impredicative instantiations.)

I didn't say anything when you were requesting use cases, so I have no right to complain, but I'm still a little disappointed that this doesn't fix my (admittedly very minor) issue: https://www.reddit.com/r/haskell/comments/3am0qa/existentials_and_the_heterogenous_list_fallacy/csdwlp2/?context=8&depth=9<https://nam06.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.reddit.com%2Fr%2Fhaskell%2Fcomments%2F3am0qa%2Fexistentials_and_the_heterogenous_list_fallacy%2Fcsdwlp2%2F%3Fcontext%3D8%26depth%3D9&data=02%7C01%7Csimonpj%40microsoft.com%7C911c05e1dc5041e685bd08d732d57261%7C72f988bf86f141af91ab2d7cd011db47%7C1%7C0%7C637033764634397513&sdata=IeOaMmtbwIFEXOBwvLkElsqqS84q50QjFD7MFW0hpK8%3D&reserved=0>

For those who don't want to click on the reddit link: I would like to be able to write something like map show ([1, 'a', "b"] :: [forall a. Show a => a]), and have it work.

Subject: Using head.hackage
Message-ID: <CAHnFXOseOnO-ORPdr0he7bkYBGr7cQ=hx=X603pLJi8JCEyscQ@mail.gmail.com>

Dear GHC devs,
As part of our work in "quick look impredicativity", we would like to test
whether any package breaks. I've read about "head.hackage" as a way to test
this fact, but I could not find any information.

Could somebody point me in the right direction? If it does not exist yet,
I'll try to summarize whatever I learn in the wiki for future reference.

Thanks in advance,
Alejandro

Hi Alejandro,
I don't know if this helps, but you can find some documentation in the repo: https://gitlab.haskell.org/ghc/head.hackage#how-to-use
Cheers,

Hi everyone,

As I've mentioned to many of you, I spent the last few weeks at ICFP,
Munihac, and bikepacking in the Alps. However, I am now back in the
States and will be moving back to my usual work schedule in the coming
days.

Needless to say, I will make a best effort to catch up on email but if
there is any particular request that you fear I may have overlooked
please do send it again.

Cheers,

- Ben

Hi Alejandro,

Indeed I have a pair of yet-to-be-published blog posts intended to
discuss exactly this. See [1] and [2]. Do let me know if you have any
questions.

Subject: Min closure payload size?
In-Reply-To: <CAMQQO3mPSEORvUMFA_05aCNr614idVx43CQ3TCv3Cc=yWQr_vw@mail.gmail.com>
References: <CAMQQO3mPSEORvUMFA_05aCNr614idVx43CQ3TCv3Cc=yWQr_vw@mail.gmail.com>
Message-ID: <CAMQQO3k=x0NN4rk2r=Y8bd3rY6RquKLnFB9Akr=eG-nCiz_F+A@mail.gmail.com>

It took 7 months to figure this one out. The compacting GC (which is enabled by
default when heap residency is above 30%) needs two bits per closure: one for
the actual "liveness" mark bit, another one for whether the object's new
location (computed during two scans in compacting GC) is in the next block in
the heap chain, instead of the current block (which the "free" pointer points
to).

This bit is important becuase in the second pass we get info pointer of an
object and update any references to it (so that they point to its new location)
in one pass (the "unthreading" business), and we can't compute the size of the
object being moved (to see whether we can move the object to the current free
location or we have to move to the next block in the heap) before we get the
info table. So if we want to avoid this second mark bit we'd need to do one pass
to get the info table, compute the size, see if it fits in the current block
etc. and then do another pass to actually "unthread" (i.e. update references to
the object with the new location).

However I was able to lift this restriction by just bumping the bitmap size, to
allocate two bits per word in the heap (instead of one). It seems to work fine
(passes the test suite), I'll test this a little bit more and then submit a MR.
This reduces closure sizes of objects with no payload, e.g.:

    {-# LANGUAGE MagicHash #-}

    import GHC.Int
    import GHC.Prim

    main = print (I# (closureSize# True))

This now prints 1 instead of 2 as before.

The instructions are quite clear. Alas, when I try to reproduce the steps
using my home-build compiler (for which I mean set the `with-compiler` in
`cabal.project` to the stage2 compiler obtained by Hadrian), I get:

> cabal new-install --lib aeson
Distribution/Client/CmdInstall.hs:(361,18)-(363,72): Non-exhaustive

Do you have any idea of what I might be doing wrong?

Thanks in advance,

Note that this only happens with `aeson`, which is the package that the
tutorial asks to add to `extra-packages` in 'cabal.project'.

Interesting, this sounds like a cabal-install bug. What does
cabal-install --version say?

Here is the output:

$ cabal --version

Alright, I'm afraid I don't really know what might be going wrong here.
Perhaps `cabal new-install --lib lib:aeson` will help? Either way, can
you open a cabal-install ticket [1] for this?

Subject: Can someone help my test my MR on *BSD?
Message-ID: <5e165d05-aafd-b4f9-0e34-d82ba309aac4@obsidian.systems>

MR !1699 deletes some code in the compiler about passing -l flags for 
the RTS. This is a layer violation and hopefully a useless one; the RTS 
config file in the package db lists external library dependencies just 
like any other package so the -l flags should be included because that 
alone.

CI passes, so everything works on Linux, Darwin, and Windows. Ben Gamari 
wanted to double check the behavior on the *BSDs, since the HAVE_* 
configure results might reasonably vary there. I got a FreeBSD VM and 
started installing the requisite ports, but I've never used any BSD 
before and don't have much time to learn it---say how to stop to the TUI 
pop-ups that prevent me building everything overnight. If someone with 
an up-and-running development environment could quickly give this change 
a spin, that would be much appreciated.

Fingers crossed, and thanks in advanced,

John

P.S. If said BSD angel wants to contribute a machine for the official 
CI, so neither me or anyone else is tempted to bug them again, that 
would also be great :)

Subject: compiler plugin pass order
Message-ID: <CA+yhPW=7rYbNQah4iSup2S36NCchBZ5QtiS9H44pLy+Ou-qveA@mail.gmail.com>

Dear all,

we started exploring Haskell-to-DotNet compiler in frames of a larger
project and would like to clarify one issue: is it possible to control the
order in the compilation pipeline in which the compiler plugins get called?
Inserting .Net compilation via Plugin seems a cleaner way than using GHC
API from scratch for a lot of reasons, but the challenge is as follows: we
compile from STG but inside the plugin core2core passes have not been
called yet, and without them some important optimizations are missing.

To illustrate the issue, this function "plus x = x + 4" gets compiled to a
nice stg function with core2core (core2core, corePrep, coreToStg, stg2stg):

plus :: forall a. Num a => a -> a

[LclIdX, Arity=2, Unf=OtherCon []] =

    [] \r [$dNum_s1bl x]

        let {

          sat_s1bz [Occ=Once] :: a

          [LclId] =

              [$dNum_s1bl] \u []

                  let {

                    sat_s1by [Occ=Once] :: Integer

                    [LclId] =

                        CCCS S#! [4#];

                  } in  fromInteger $dNum_s1bl sat_s1by;

        } in  + $dNum_s1bl x sat_s1bz;

Inside the plugin, it is only possible to do the same pipeline but
*without* the core2core passes, and it gets compiled with additional THUNK:

[sat_s1gp :: forall a. Num a => a -> a

 [LclId] =

     [] \r [$dNum_s1ga x]

         let {

           sat_s1go [Occ=Once] :: a

           [LclId] =

               [$dNum_s1ga] \u []

                   let {

                     sat_s1gn [Occ=Once] :: Integer

                     [LclId] =

                         CCCS S#! [4#];

                   } in  fromInteger $dNum_s1ga sat_s1gn;

         } in  + $dNum_s1ga x sat_s1go;,

 plus :: forall a. Num a => a -> a

 [LclIdX] =

     [] \u [] sat_s1gp;,

So the question is - is there any way to ask GHC to run the plugin as LAST
in the core2core passes process so that we get the optimized core and
convert it to stg?

Alternatively, maybe STG plugins should also be introduced? Should be an
easy enough change. Thank you for comments / suggestions / ideas!

"Con.hs" (or the same with any other extension) is a reference to the
console device on Windows. Same for Prn.whatever and other filenames that
overlap device names.

Looks like an issue needs raising then. I'll take care of it.

It looks to me like `eqType` accounts for type synonyms but not associated
types. Is there a variant that compares modulo associated types, or perhaps
a type normalizing operation to apply before `eqType`?

Hi Conal,

I've had success with `FamInstEnv.topNormaliseType` in the past. `eqType`
doesn't take `FamInstEnvs`, so I'm pretty sure it can't look through family
instances by itself.

Cheers,
Sebastian

Can you be more explicit?

I think you are referring to Type.eqType in GHC itself?

I think you might want to apply FamInstEnv.normaliseType first.

Subject: eqType modulo associated types?

It looks to me like `eqType` accounts for type synonyms but not associated types. Is there a variant that compares modulo associated types, or perhaps a type normalizing operation to apply before `eqType`?

Thanks, - Conal

Just so we are all on the same page: Precisely what type of plugin are
you implementing?

If it's a Core plugin then you should be able install your plugin
anywhere in the list of CoreToDos given to the installCoreToDos
function.

Subject: Changes in GHC API modularity with the "Encode shape information in
 PMOracle" MR
Message-ID: <CAKe9RRE-rwedo8ceOg0twsJ=YRwBHEk+CaZ3adiMTsaJNnjzaw@mail.gmail.com>

Some time back, the `ghc-lib` project split into two targets :
`ghc-lib-parser` for those projects that just need to produce syntax trees
and `ghc-lib` (re-exporting `ghc-lib-parser` modules) having the remaining
modules for projects that need to go on and distill parse trees to Core.
The idea of course was to reduce build times for tools like hlint that only
need parse trees.

Roughly, `ghc-lib-parser` got about 200 files and `ghc-lib` 300. Today
after landing `7915afc6bb9539a4534db99aeb6616a6d145918a`, "Encode shape
information in `PmOracle`", `ghc-lib-parser` now needs 543 files and
`ghc-lib` gets just 25.

That may be just bad luck for `ghc-lib-parser` and the way it has to be but
I thought I should at least mention the knock-on effect of this change on
the modularity of the GHC API in case this consequence hasn't been
considered?

Hi Shayne,

Sorry to hear that! We didn't consider modularity at all and I would be
happy to try to refactor in a way that would allow `ghc-lib-parser` to be
properly separated again.
I'm fairly certain that I didn't directly touch anything parser related,
but apparently the new cyclic import of PmOracle within TcRnTypes (which is
also exposed from `ghc-lib-parser`) pulled in the other half of GHC.
I'll see if I can fix that tomorrow, if only by extracting a separate
`Types`-style module.

Cheers,
Sebastian

That sounds awesome. Tremendous. Thank-you! Please feel free to reach out
to me if there's anything I can do to help your analysis[*]!

[*] For the record, the procedure for calculating the `ghc-lib-parser`
modules is a little complicated by there needing to be some generated
equivalents of `.hsc` files present for this to work but the procedure is
at the end of the day just `ghc -M` invoked over `Parser.hs`.

This is precisely the problem I was worried about in April.

https://mail.haskell.org/pipermail/ghc-devs/2019-April/017493.html

Any fix should ensure adding a test to make sure it doesn't happen again.

Hmm. The issue of build parallelism is kind-of orthogonal to .hs-boot
files/circular imports.

The impact of .hs-boot files on build parallelism depends on their
announced imports; at least in my semantic model of them (which might be
incorrect) they just break cycles.
The degree of parallelism is visible as a property of this DAG where cycles
are broken through insertion of .hs-boot nodes.

The issue here is one of transitive dependencies, which is a property on
the original cyclic dependency graph.

So while we have the dependency graph

HsExpr <--> TcRnTypes <--> PmOracle

This is of no issue for build parallelism, because the .hs-boot files
remove "feedback vertices" from the graph, rendering it acyclic:

TcRnTypes.hs-boot <- HsExpr <- TcRnTypes <- PmOracle
PmOracle.hs-boot <- TcRnTypes

Yet a package including HsExpr must also include PmOracle to compile.

The parallelism issue is best tackled by hadrian based profiles, on which
we could compute try to come up with the optimal schedule and compare it
across multiple CI runs.
But the dependency issue here is rather specific to the set of modules that
should be included in ghc-lib-parser, I'm afraid, and I don't see how to
solve it in a general way other than pre-computing the set of transitive
dependencies for specific blessed modules. Which might be a thing we
want... One set for each major entry point to the compiler pipeline, for
example.

Shayne,

out of curiosity, could you find out which of the three modules DsMonad,
FamInst and TcSimplify lead to the blowup? If it's not too much of a
hassle, that is.
These are the only imports of PmOracle that aren't already exported from
ghc-lib-parser.

Cheers,
Sebastian

Subject: Fwd: Why do Constraint Tuple data constructors exist?
In-Reply-To: <CADA66oFGAmPTzUOudc7PBjMiRPLjOK7oqwmr2OpSCXEUPMBv6w@mail.gmail.com>
References: <CADA66oFGAmPTzUOudc7PBjMiRPLjOK7oqwmr2OpSCXEUPMBv6w@mail.gmail.com>

My question arrised in the following context:

```
module ForEachHelper where

import Data.Kind
import GHC.TypeLits

type family ForEach (c :: k -> Constraint) (xs :: [k]) :: Constraint where
    ForEach c '[] = ()
    ForEach c (x:xs) = (c x, ForEach c xs)

type family Replicate n x where
    Replicate 0 x = '[]
    Replicate n x = x : Replicate (n-1) x

data ForEachHelper n c x where
    ForEachHelper :: ForEach c (Replicate n x) => ForEachHelper n c x

-- The following solve function was actually in another module from the
definitions above:

solve :: ( KnownNat n, c x
         -- Solved via plugin:
         -- , ForEach c (Replicate n x)
         ) => p c -> q x -> ForEachHelper n c x
solve pc px = ForEachHelper
```

I was trying to write a plugin that could solve the (ForEach c (Replicate n
x)) constraint.
I need an EvTerm that this constraint.  The first thing I tried was to use
the given EvTerm
for the (c x) constraint without change.  This causes the program to
compile but ultimately
and, perhaps not surprisingly, it segfaults when code relies upon the
constraint.

Then I decided that (ForEach c (Replicate n x)) is a constraint tuple and
the
proof term should be a tuple constructed using a constraint tuple data
constructor.  However, this is apparently not possible.  When I tried the
following code in the initialization of my plugin:

    cpairCon <- tcLookupDataCon (cTupleDataConName 2)

it triggers an error:

    Can't find interface-file declaration for data constructor
GHC.Classes.(%,%)

Searching GHC source, I cannot find where or how constraint data
constructors
are used and notes on commit ffc21506894c7887d3620423aaf86bc6113a1071 were
not
helpful to me either.  Why do constraint tuple data constructor names exist
at
all if we cannot use them for anything?  Is it possible for a plugin to
solve
the (ForEach c (Replicate n x)) constraint by some other means?

Getting you some raw data to look at but first results indicate at least
that `DsMonad` is pulling in `nativeGen`, `llvmGen`, `stgToCmm`,
`simplCore`, `hieFile` and so on.

I'm not sure if this is directly relevant to your issues around
GHC.Classes.(%,%), but there are some issues with using tuples for
Constraints. Namely that they can only be fully applied, and do not exist
naked as

(,) :: Constraint -> Constraint -> Constraint.

With UndecidableInstances, etc. you can fabricate a class like

class (a,b) => a & b
instance (a,b) => a & b

and then use (&) partially applied, and modulo a little bit of plumbing on
the backend.

Maybe this would be enough to unblock you?

Hi GHC devs,
I have made a rebase to bring my merge request [
https://gitlab.haskell.org/ghc/ghc/merge_requests/1659] up to date with the
current GHC codebase. In the process there were some conflicts (as
expected) which I could solve. However, now that I have pushed the result,
I get these messages from the CI infrastructure:

$ validate-whitespace .git $(git rev-list $base..$CI_COMMIT_SHA)

What is the right approach to fix these problems? I can fix the whitespace

You should rebase + squash your patch.

Or, if you just want to look at CI, turn off the linters for now.

Subject: Test cases and missing RTS linker
Message-ID: <20190918131530.GA19028@dyn-9-152-222-56.boeblingen.de.ibm.com>

Hi all,

How is a test case supposed to be marked if it makes use of the RTS linker
which itself is not supported on some architectures?

For example, some test cases are marked for a particular architecutre like
PowerPC64 that it fails because of a missing RTS linker.

Style (A)

  test('T10052', [when(arch('powerpc64') or arch('powerpc64le'),
                  expect_broken(11259)), req_interp],
       makefile_test, ['T10052'])

Whereas another test case is marked to be skipped if RTS linker is missing.

Style (B)

  test('static-plugins',
       [extra_files(['simple-plugin/']),
        unless(config.have_RTS_linker, skip),
        expect_broken_for(16803, prof_ways),
        extra_run_opts('"' + config.libdir + '"')],
       compile_and_run,
       ['-package ghc -isimple-plugin/'])

If style (A) is the way to go, then for every architecture which does not
support the RTS linker a when-clause must be added.

If style (B) is the way to go, then shouldn't we change all test cases of style
(A) to style (B)?

Personally I prefer style (B) over (A) because it makes it easier to add an
architecture where the RTS linker is not provided. Even if the RTS linker is
provided after some time, then the test case must not be changed. Once
PowerPC64 supports the RTS linker all when-clauses must be removed.

Any thoughts which style to use?

Cheers,
Stefan

Subject: GHC 8.10.1 Release Plan
Message-ID: <87sgote5bb.fsf@smart-cactus.org>

tl;dr. If you have unmerged work that you would like to be in GHC 8.10 please
       reply to this email and submit it for review in the next couple
       of weeks.


Hello everyone,

Now that GHC 8.8.1 is behind us it is time that we begin thinking about
8.10. There seems to be broad consensus within the subset of the
community that I sampled that we should try to hold to the usual release
date near the end of year for 8.10.1. I believe that this is a feasible
goal with the caveat that we push the final release back by a couple of
weeks in recognition that busy schedules of the holiday season tends to
throw unexpected wrenches into the release process.

In particular I would suggest the following concrete schedule:

    October  18 2019:  start of one week freeze in preparation for branching
    October  25 2019:  ghc-8.10 branch cut
    November 8  2019:  8.10.1-alpha1
    November 22 2019:  8.10.1-alpha2
    December 6  2019:  8.10.1-alpha3
    December 20 2019:  8.10.1-rc1
    January  10 2020:  Final 8.10.1 release

If you have yet-unmerged work that you would like to see in GHC 8.10
please do be in touch and open a merge request ASAP.


One obvious question is how we will avoid the many delays that plagued
the 8.8.1 release. Without delving too deep into the specific reasons for
these delays, the reasons fell into two buckets:

 1. delays due to CI stabilization
 2. coordination delays with upstream libraries
 3. fallout from MonadFail changes which landed only late in the release
    cycle

Of these, (1) is largely behind us and (3) will be avoided by ensuring
that core libraries changes are landed *before* the branch date.

This leaves consideration (2). The problem of upstream library
coordination has always been a tricky one but has grown more acute as
our release schedule has accelerated. While no technical solution will
eliminate the issue entirely, we believe that decoupling GHC's release
schedule from those of its dependencies' is an important mitigation.
We will be discussing this with upstream library maintainers in
the coming weeks to establish how we can ensure that releases are
available well ahead of the GHC 8.10 release, ideally by alpha2.

Cheers,

- Ben

I also really think we should fix 15455 before 8.10 is released.

It's a major space leak in the simplifier which has already been
present for 3 major versions now which affects a popular package.

Please consider https://gitlab.haskell.org/ghc/ghc/merge_requests/1742.
I thought it would be a hassle to write tests for it, but I figured
out a nice way.

I set the milestone to 8.12.1, because I expected more problems, but
it seems like things are going smoothly and this is becoming a
candidate for 8.10.1.

Hello Ben,

I hope to push the threaded RTS by default MR over the line now when the
GHC proposal has been accepted.

Here is the MR: https://gitlab.haskell.org/ghc/ghc/merge_requests/538

It has some unstable test suite failures: they appear only in some
configurations.
Notably, validate-x86_64-linux-deb9-debug fails more than others:
https://gitlab.haskell.org/ulysses4ever/ghc/pipelines/10289
I'd appreciate if someone could take a look and suggest a path forward.

I'd like to get !1730 in, and ideally !1739 if it doesn't require a

Hi Ben,

I think we should complete 
https://gitlab.haskell.org/ghc/ghc/issues/13009 for 8.10 (to avoid a 
release with inconsistent module hierarchy and to make backporting easier).

Cheers,

Subject: Filtering GitLab mentions
Message-ID: <8736gliq5c.fsf@smart-cactus.org>

Hi everyone,

During a discussion on procedural matters earlier today it was (yet
again) noted that GitLab notification emails are quite chatty and
consequently it is easy to lose the signal in the noise.

However, during this discussion we also realized that much of the issue
can be mitigated with a simple email filter to identify explicit
@-mentions. I find that:

  from:gitlab.haskell.org and @bgamari and header:X-GitLab-Discussion-Id

isolates emails arising from @-mentions fairly effetively.

If your MUA doesn't support filtering by arbitrary headers you can
replace the "header" predicate with simply a mention of the word
"commented".

If you are active on GitLab I would encourage you to setup such a
filter; I was surprised by how many comments I had overlooked.

Cheers,

- Ben

Message-ID: <CALuQ0m9SkgRidDn1XyQVTtusQXa4o8dMQ4Mxi0O6vfG0xdPiqA@mail.gmail.com>

Hi,

It seems that basically every new issues gets triaged with the 8.10.1
milestone, what does this mean?

It seems like a lot of the issue's won't get fixed for 8.10, or at any
foreseeable point in the future which dilutes the milestoning.

Therefore I don't think we should assign a certain milestone to a
ticket unless either

1. The issue is considered necessary to fix for that milestone (ie, a
regression)
2. Someone is planning to work on the ticket for that milestone (ie, a
feature/improvement)

Then the milestone actually has some meaning.

Cheers,

Matt

I generally set the milestone of new tickets that I think could
plausibly be handled before the next merge window to the next major
release. I then go through the list and bump tickets to the next
milestone prior to forking.

This is an extension of our treatment of milestones under Trac,
where the field would IIRC default to the next major release and
perform mass re-milestonings prior to release, eventually de-milestoning
a ticket if it is remilestoned several times with no visible progress.

This approach has the nice property that it ensures that each ticket is
looked at periodically. On the other hand, it also means that the next
release milestone is quite cluttered.

I wouldn't be opposed to reconsidering this policy.

Cheers,

- Ben

Even though I no longer work at a Windows shop, I've been watching
https://gitlab.haskell.org/ghc/ghc/issues/7353 with great interest. Last I
knew Tamar Christina was heroically hacking away on a new IO manager for
Windows.

Although my low-level Windows knowledge is likely insufficient for me to
contribute significantly, I'd be very interested in testing the new IO
manager and helping with debugging in any way I can. How might one go about
building a GHC with this new Windows IO manager?

Thanks, as always, for all your hard work,

Travis Whitaker

Hi Travis,

The current MR with my WIP is at
https://gitlab.haskell.org/ghc/ghc/merge_requests/1224

This should build without a problem (on Windows, haven't sorted the Linux
build failures yet). The threaded version passes the testsuite (i.e.
-threaded +RTS --io-manager=native) but the non-threaded
version has proven tricky to support correctly. That one still has a
deadlock that I am debugging (though I have made significant progress since
I last updated that MR).

I will push the updated code this weekend. Though I'm afraid that based on
it not getting any review of the design so far and my current work
commitments I won't be able to
get this done for GHC 8.10. So I will punt it to GHC 8.12.

The MR contains a list of TODOs in case you're wondering what's left on it.

Thanks,
Tamar

Hi devs,

I believe threadstatus-9333 is more fragile than it's listed as. See https://gitlab.haskell.org/rae/ghc/-/jobs/163182 <https://gitlab.haskell.org/rae/ghc/-/jobs/163182>, where I haven't been anywhere near this area of the code...

Also, on a separate test, I found that compact_gc got killed. See https://gitlab.haskell.org/rae/ghc/-/jobs/163526 <https://gitlab.haskell.org/rae/ghc/-/jobs/163526>.

Should these be fragile?

Thanks,
Richard

Yes, you are correct; I fixed this earlier this week in !1789.

Hmm, it looks like it timed out in the ghci way. I would guess that the
interpreter is simply too slow. Looking back at the test tracking
database it seems this failure has only occurred twice since we started
tracking.

I have opened #17253 to track this and will mark the way as fragile.

Cheers,

Subject: How does the ambiguity check work
Message-ID: <6ef429d2-5637-99f4-1f8d-27d0ee5faa0d@vanbruegge.de>

Hi lovely people,

I am currently trying to wrap my head around the ambiguity check in GHC.
In particular for those two instances:

```

class RowEquality where
    rowEqual :: Bool

instance (1 ~ 2) => RowEquality where
    rowEqual = True

instance ( ("foo" ::: Int & RNil) ~ ("bar" ::: String & "foo" ::: Int &
RNil) ) => RowEquality where
    rowEqual = True
```

I would expect them to behave the same but the second one throws an
error when trying to compile the module (*before* using `rowEqual` -
that would obviously throw a type error in both cases):

```
Test.hs:24:10: error:
    • Could not deduce: (| "foo" :: Int |)
                        ~ (| "bar" :: [Char], "foo" :: Int |)
      from the context: (("foo" ::: Int) & RNil)
                        ~ (("bar" ::: String) & (("foo" ::: Int) & RNil))
        bound by an instance declaration:
                   ((("foo" ::: Int) & RNil)
                    ~ (("bar" ::: String) & (("foo" ::: Int) & RNil))) =>
                   RowEquality
        at Test.hs:24:10-94
    • In the ambiguity check for an instance declaration
      To defer the ambiguity check to use sites, enable AllowAmbiguousTypes
      In the instance declaration for 'RowEquality
```

I have troubles to understand why GHC tries to solve the constraint
there. I worked through `checkAmbiguity` in `TcValidity` and the
function it calls, but from what I can see is that it also tries to
solve the `(1 ~ 2)` and fails in the same way as with the second one. I
cannot find any reason why the two are treated differently.

Thank you
Jan

Hi Jan,

The ambiguity check has a simple description. To test if a type `ty` is ambiguous, do this:

```
x :: ty
x = x
```

Iff that type-checks, the type is unambiguous. That's it!

The check does not manufacture a binding `x`, but the implementation runs through the type-checking process for a binding just like the one I've written here.

In your case, I have two hypotheses:
1. Presumably, you have a solver plugin at work. That may explain the difference in behavior between the two cases.
2. There may be kind variables at work, and these may end up ambiguous. It's definitely worth trying with -fprint-explicit-kinds.

I hope this helps!
Richard

IIUC Jan is working on a ghc branch, not a plugin. But perhaps this ticket
will point in the right direction anyway? HTH.
