Hey Everyone ... I'm concerned, it looks like ghc 8.6.2 on OSX doens't pass validate or even a rudimentary `make test` I'm not sure how to make heads or tails of all these errors, and it looks like a huge amount of dev work over time has accumulated some failures .... could the code owners on these sub systems at least help me make heads or tails of these errors? SUMMARY for test run started at Mon Nov 19 19:48:18 2018 EST 0:28:32 spent to go through 6516 total tests, which gave rise to 25425 test cases, of which 18538 were skipped 41 had missing libraries 6380 expected passes 92 expected failures 2 caused framework failures 0 caused framework warnings 0 unexpected passes 365 unexpected failures 7 unexpected stat failures Unexpected failures:

Unused imports

I'm getting lots of these failures. Has someone forgotten to do a submodule update? I'm up to date on a clean head and have done 'git submodule update' Help!

Head badly broken
by Simon Peyton Jones 23 Nov '18

23 Nov '18

>From a clean build of HEAD, I’m getting tons of failures like this T5490.hs:19:22: error: Illegal symbol '.' in type Perhaps you meant to write 'forall <tvs>. <type>'? | 19 | | ∀ e . Exception e ⇒ Failure e | ^ This is in typecheck/should_compile Then I also get errors in things like typecheck/should_fail/tcfail190, where the output differs from the .stderr file in by the presence of bullets in GHC’s output. The bullets seem to be missing from the tcfail190.stderr file. This is really painful. I can’t validate. Any ideas? Simon

How to distinguish local ids from imported ones in Stg? Confused about isLocalId/isLocalVar
by Ömer Sinan Ağacan 23 Nov '18

23 Nov '18

Hi, I just found out that semantics of isLocalId/isLocalVar change during compilation. I realized this the hard way (after some debugging) but later realized that this is documented in this note: (the last line) Note [GlobalId/LocalId] ~~~~~~~~~~~~~~~~~~~~~~~ A GlobalId is * always a constant (top-level) * imported, or data constructor, or primop, or record selector * has a Unique that is globally unique across the whole GHC invocation (a single invocation may compile multiple modules) * never treated as a candidate by the free-variable finder; it's a constant! A LocalId is * bound within an expression (lambda, case, local let(rec)) * or defined at top level in the module being compiled * always treated as a candidate by the free-variable finder After CoreTidy, top-level LocalIds are turned into GlobalIds So after after simplification we can't distinguish a local id from an imported one. Apparently I'm not the only one who was confused by this. In StgLint we check in-scope variables with this: checkInScope :: Id -> LintM () checkInScope id = LintM $ \_lf loc scope errs -> if isLocalId id && not (id `elemVarSet` scope) then ((), addErr errs (hsep [ppr id, dcolon, ppr (idType id), text "is out of scope"]) loc) else ((), errs) Note that isLocalId here returns false for local but top-level bindings. Because of this if I drop some top-level bindings in the module I don't get a lint error even though some ids become unbound. I need to distinguish a top-level bound id from an imported id for two things: - I want to make sure, in StgLint, that bindings in the Stg program are in dependency order (uses come after definitions). For this I need to treat imported ids as already bound, but for top-level bound ids I need to check if I already saw the definition. - I want to run an analysis to map top-level bindings to whether they can contain CAF refs. For this for a top-level bound id I should check the environment, but for imported ids I should check idInfo. The second analysis depends on the first property for efficiency. I could assume that the first property holds and then always check the environment first in the analysis, and treat ids that are not in the environment as imported, but that seems fragile. I'm wondering why we have to turn LocalIds into GlobalIds after simplification. The note doesn't explain the reasoning. Would it be possible to preserve idScope of ids during the whole compilation? Thanks, Ömer

split_marker crash
by Simon Peyton Jones 21 Nov '18

21 Nov '18

Urrgh. I have this panic in a clean validate (sh validate -fast) on my branch wip/T15809. ghc-stage1: panic! (the 'impossible' happened) (GHC version 8.7.20181119 for x86_64-unknown-linux): split_marker_entry Please report this as a GHC bug: http://www.haskell.org/ghc/reportabug libraries/ghc-prim/ghc.mk:4: recipe for target 'libraries/ghc-prim/dist-install/build/GHC/Types.o' failed Yes, it's a branch not identical to HEAD, but I have done nothing concerning split_markers. Sigh. What should I do? Simon

are ghc commits only getting make fast test'd on OSX?
by Carter Schonwald 20 Nov '18

20 Nov '18

thats the only explanation of why i see soooo many test suite failues of a GHC RELEASE when i do make test ... why do we not have a full ./validate run on each tier one platform as part of some official release check list? DO WE HAVE a checklist for releases? if not, we should, this shouldn't be happening

Force-push
by Simon Peyton Jones 19 Nov '18

19 Nov '18

Devs When I rebase wip/T15809 (which has about 40 patches on it), and force-push, it generate a lot of Trac mail. Sorry about this. I don't know how I can make that not-happen. You can safely delete it! Simon

Validate on master broken.
by Andreas Klebinger 16 Nov '18

16 Nov '18

Hello Devs, it seems Simons patch "Smarter HsType pretty-print for promoted datacons" broke ./validate. > I discovered that there were two copies of the PromotionFlag > type (a boolean, with helpfully named data cons), one in > IfaceType and one in HsType. So I combined into one, > PromotionFlag, and moved it to BasicTypes. In particular haddock seems to have depended on the changed constructors. If anyone with access and knowledge of haddock could fix this I would be grateful. Cheers Andreas
