TcPluginContradiction understanding problem and converting Type to Typeable
by alice 11 Apr '18

11 Apr '18

Hello, I'm writing a type-checker plugin for ghc, and I'm stuck on two problems. I can't understand how does TcPluginContradiction work. My problem is, when I do TcPluginContradiction listOfFailedConstraints and run the plugin on something which should fail, compiler output contains strange errors for places which doesn't produce any errors when the rest type checks. And it can be seen from debug that listOfFailedConstraints does contain only the constraints that are expected to fail. For example my plugin should type check Set '[Int]) ~ Set '[Int, Int], and should not Set '[Int, Bool, Int] ~ Set '[Int]. And everything is great when I run it on the first case, but if I run it on the both first and second, the compiler output will contain «Couldn't match type ‘Set '[Int]’ with ‘Set '[Int, Int]’» and «Couldn't match type ‘Set '[Int, Bool, Int]’ with ‘Set '[Int]’». My ghc version is 8.2.2. Also how does ghc converts Type from https://hackage.haskell.org/package/ghc-8.2.1/docs/src/TyCoRep.html#Type <https://hackage.haskell.org/package/ghc-8.2.1/docs/src/TyCoRep.html#Type> to Typeable/TypeRep from https://hackage.haskell.org/package/base-4.10.1.0/docs/src/Data.Typeable.In… <https://hackage.haskell.org/package/base-4.10.1.0/docs/src/Data.Typeable.In…>? I’d like to use a function (if there exists one) that takes Type and returns its fingerprint (https://hackage.haskell.org/package/base-4.10.1.0/docs/src/GHC.Fingerprint.… <https://hackage.haskell.org/package/base-4.10.1.0/docs/src/GHC.Fingerprint.…>). Thank you for your time, Alice.

ghc-8.4.1-release tag
by Joachim Breitner 10 Apr '18

10 Apr '18

Hi, I noticed that the tag ghc-8.4.1-release points to f31c40efdc918bc9da8a325327ba5a472bd6ea9e but the tarball has different content: $ cat /tmp/ghc-8.4.1/GIT_COMMIT_ID 0a3e2f324dbd525d626ebd3d97e8ffa1cf2f0ffb Ben, would you mind updating the git tag to reflect reality, to avoid confusion (it’s be a forced tag update, but still better than inconsistent information). Cheers, Joachim -- Joachim “nomeata” Breitner mail(a)joachim-breitner.de https://www.joachim-breitner.de/

How do you build the haddocks for a boot library?
by Simon Jakobi 09 Apr '18

09 Apr '18

Hi, I have some changes to the haddocks in ghc-prim which are re-exported from base. In order to check that I got the syntax right I've tried to build the haddocks by following https://ghc.haskell.org/trac/ghc/wiki/Building/Docs#Haddockdocumentation. Sadly, when I run "make html" in libraries/ghc-prim or libraries/base I get the following error: GNUmakefile:3: libraries/ghc-prim/mk/sub-makefile.mk: No such file or directory make: *** No rule to make target 'libraries/ghc-prim/mk/sub-makefile.mk'. Stop. What should I do instead? Cheers, Simon

New slow validate errors
by Ömer Sinan Ağacan 08 Apr '18

08 Apr '18

Hi, I see a lot of these errors in slow validate using current GHC HEAD: ghc: panic! (the 'impossible' happened) (GHC version 8.5.20180407 for x86_64-unknown-linux): Each block should be reachable from only one ProcPoint This wasn't happening ~10 days ago. I suspect it may be D4417 but I haven't checked. Ömer

Why does the RTS run GC right before shutting down?
by Ömer Sinan Ağacan 06 Apr '18

06 Apr '18

Hi, I'm wondering why we run GC in this line: https://github.com/ghc/ghc/blob/master/rts/Schedule.c#L2670 I went back in commit history using git blame and found the commit that introduced that line (5638488ba28), but it didn't help. Does anyone know why we need that line? Thanks, Ömer

[ANNOUNCE] GHC 8.4.2-rc1 now available
by Ben Gamari 05 Apr '18

05 Apr '18

Hello everyone, The GHC team is proud to announce the first release candidate of 8.4.2. the source distribution, binary distributions, and documentation are available at https://downloads.haskell.org/~ghc/8.4.2-rc1 This release follows so closely to 8.4.1 due to a number last-minute bug-fixes that didn't quite make it into 8.4.1. This includes fixes for: * #14705, the interpreter being broken on some systems * #14779, where the compiler produces invalid code when used with -g * #14891, where a selection of GHC testsuite cases fail on OS X * #5129, where the simplifier would incorrectly reorder evaluation in under some conditions. Since this is a relatively small bugfix release we are bypassing the alpha releases and moving right to the release candidate stage. If all goes well the final release will be cut next week. Happy testing Cheers, - Ben

More windows
by Simon Peyton Jones 04 Apr '18

Tamar I've noticed that "sh" (which is invoked at lot by make etc) takes AGES to start up. At least I think it's 'sh' that is causing the delay. I think it's c:/msys64/usr/bin/sh.exe >From searching the web (eg https://www2.cs.duke.edu/csl/docs/unix_course/intro-60.html) it seems likely that it executes c:/msys64/etc/profile first. And If I put an 'echo' at the start and end of that file, they do seem to take place with a significant gap between them. I have not started sprinkling more echos, but does that ring any bells? Can I replace 'sh' with c:/msys64/usr/bin/bash.exe, which seems to be faster? (My evnt variable SHELL already points to bash.exe. ) And if so, how would I do that? An environment variable. Physically copy bash.exe to sh.exe? Or what? Thanks Simon

Perl locale

Hi Tamar One other thing happened to me when building GHC, very early. See below. I think the perl concerned is c:/msys64/usr/bin/perl. Any ideas?

8.5 build failure
by John Leo 03 Apr '18

03 Apr '18

Hi everyone, I pulled from head this morning and rebased my current work on it, and am getting a build error I've never seen before. I don't think it's due to any of my own changes, and everything built fine last time I tried just a couple days ago . I'd pulled both code and submodules. I did make clean, ./boot, ./configure, and then make. The last few lines of the output are below. This is on a Mac using GHC 8.2.2. Let me know if you need any more info.
