Purely using the parser entry points
by Matthew Pickering 03 Jul '15

03 Jul '15

I've been working with the new parser entry points - they have been very useful. Ostensibly the new parser entry points are pure functions but they require a copy of DynFlags. As far as I can work out there's no pure way to reliably construct DynFlags but it also seems that the Parser doesn't use any of the impure mutable parts of it. This makes it tricky to write pure functions such as "parseExprFromString :: String -> LHsExpr RdrName" which would use some sort of dummy configuration. So far I've tried using "unsafeGlobalDynFlags" which (expectedly) fails occasionally. I've found a more reliable method to be the following which relies on unsafePerformIO. getDynFlags = unsafePerformIO $ GHC.defaultErrorHandler GHC.defaultFatalMessager GHC.defaultFlushOut $ GHC.runGhc (Just libdir) GHC.getSessionDynFlags The question is - is this use of unsafePerformIO safe? Is there a better way to purely initialise a copy of DynFlags? Thanks, Matt

NOTE: Going on a vacation for a while...
by Austin Seipp 03 Jul '15

03 Jul '15

Hi *, A few weeks ago, as the close of the 7.10.2 release came closer, I decided to take a vacation; one I've needed for a little while now. Well, it's been a bit long in the tooth with the last RC (and my terrible home internet has blocked me for the past day at least) - but that time has come! After the release of 7.10.2 RC2 today, I'm provisionally be "gone" until the end of August. This week is basically done, so I'm mostly going to be gone. I plan on making my return at ICFP 2015, more or less (end of August in Vancouver). I say "gone" with finger quotes, because I will still be around - but not doing GHC stuff every day for work. I am still part of the Haskell.org Infrastructure team, so I'm still going to be around every week. You can still catch me on IRC, email, or elsewhere. I'll just have a higher latency. My laptop will be around. If you have a problem with Phabricator, emails seem to not get delivered, or server instability - please do CC me directly in an email! That'll make sure it hits my inbox so I can at least respond by the next day. I hope to actually fix some infrastructure issues, so again, please do contact me if something is wrong. But for GHC? In particular, for the interim, Ben Gamari, who has recently joined us at Well-Typed, will be filling in for me. Ben has a lot of experience working on GHC and we're happy to have him - he'll be doing the final 7.10.2 release here in a week or two I think, and I'm sure things will go just fine in the mean time after that. Ben is already subscribed to every GHC patch that comes in on Phabricator, so he'll be doing a lot of code review for the things that come through Phabricator. You can keep me on the reviewer list as a habit - you don't need to change anything here. In the aftermath of this after August, I'll return, and Ben and I plan to keep doing our thing together, and we'll all move towards 7.12.1. But in the mean time, I'll be relaxing. I might find some time for a recreational patch or two as well, but we'll see! Thanks * -- Regards, Austin Seipp, Haskell Consultant Well-Typed LLP, http://www.well-typed.com/

RTS dependency on POSIX signals
by Jakub Zalewski 02 Jul '15

02 Jul '15

Dear all, I am working on porting GHC to [native client]( https://developer.chrome.com/native-client) and I am currently trying to figure out how to port the RTS. On POSIX systems RTS seems to depend on two POSIX signals: timer signal and interrupt signal; while native client has very limited POSIX signal support --- for instance it does not define *siginfo_t* (which is referenced in the base package). So far, I know how to deal with the dependency on the timer signal, as while browsing the source code in rts/posix/Itimer.c, I noticed that on iOS the timer is not using POSIX signals to implement the timer signal. I wanted to ask if there are any other POSIX signal dependencies in the RTS, and would it safe to disable any signal handling in the RTS if I know that there will be no interrupt signals sent to the RTS? Best wishes, Jakub

Help Building GHC on Windows to avoid LGPL
by Elliot Cameron 01 Jul '15

01 Jul '15

Hi all, I'm very new to GHC's source, but I'm trying to build a version of GHC for Windows that uses integer-simple instead of integer-gmp. My goal is to provide builds for MinGHC and stack to help alleviate the LGPL concerns on Windows: https://github.com/commercialhaskell/stack/issues/399 So far I have not met with much success. I'm following this rather well-written tutorial: https://ghc.haskell.org/trac/ghc/wiki/Building/Preparation/Windows Following those instructions exactly (I think) has brought me to a failing build. Some variables that the instructions don't pin down are as follows: I'm using the mingw64_shell on a Windows 8.1 64-bit machine. I'm trying to build the code at tag ghc-7.10.1-release and I'm using GHC 7.8.4 64-bit to do it. I've updated everything to the latest with pacman. I did not configure a mk/build.mk file. I have tried copying the sample configuration but got the same result. Is there anyone who'd be willing to help me troubleshoot? Or if you have a working setup, a stop-gap measure would be to build 32- and 64-bit versions of the last few most recent versions of GHC with integer-simple so we can use them for MinGHC and stack. Here's the last bit of what I'm seeing.

RE: [Diffusion] [Build Failed] rGHC0aaea5b8345f: Tiny refactor plus comments
by Simon Peyton Jones 29 Jun '15

The builds seem to be failing with perf failures for haddock.Cabal haddock.compiler but that doesn't seem to happen for me. It looks as though it started with rGHC*rGHC0b7e538a09bc: Allow recursive unwrapping of data families but since I can't reproduce it, it's hard to investigate. I can't even see what performance number has changed, because harbourmaster only shows the tail of the log. Any insight from others would be useful. Joachim: do the nofib logs show any changes?

arc land failing
by Simon Marlow 29 Jun '15

29 Jun '15

I haven't been able to arc land in GHC for a while, it always complains about not being able to fast-forward, like this: $ git pull --rebase First, rewinding head to replay your work on top of it... Applying: Mask to avoid uncaught ^C exceptions $ arc land Landing current branch 'ghci-mask'. Switched to branch master. Updating branch... Switched back to branch ghci-mask. Exception Command failed with error #128! COMMAND git pull --ff-only --no-stat STDOUT (empty) STDERR fatal: Not possible to fast-forward, aborting. (Run with --trace for a full exception trace.) [1] 11904 exit 1 arc land Anyone able to look into this? Cheers, Simon

Notice that the kind of normalization I'm talking about, specified in the link I provided, does not include this kind of normalization. Because it requires the IO monad to perform correctly, and only on real paths. Here is the link again: https://hackage.haskell.org/package/filepath-1.1.0.2/docs/System-FilePath-P… Full canonicalization of paths, stripping out redundant ".." and whatnot, should certainly be done in a separate function, in IO.

Different behavior in ghci 7.8.3 vs 7.10.1?
by Dominick Samperi 27 Jun '15

27 Jun '15

Hello, I'm trying to run code that works with ghci 7.8.3 under ghci 7.10.1 but this fails. Under 7.8.3, when I run from the shell: export LD_LIBRARY_PATH=thepath ghci -lmylib -fno-ghci-sandbox mydriver.hs I see the usual startup diagnostics along with Loading object (dynamic) mylib ... done final link ... done [1 of 1] Compiling Main Main> But under 7.10.1, when I do the same, there is no indication that linking happens, and when I try to run the program there are undefined references. I probably missed the post that explains this behavior. Can somebody provide a pointer to a work-around? Thanks, Dominick

help with recognizing symbolic identifiers
by Richard Eisenberg 27 Jun '15

27 Jun '15

Hi devs, I've just posted #10583 (http://ghc.haskell.org/trac/ghc/ticket/10583) about fixing up basicTypes/Lexeme.hs. As stated in the ticket, I'm happy to do the hacking, but I need some advice. My most pressing question is this: Examine the following functions, which all should do the same thing * isVarSymChar: https://github.com/ghc/ghc/blob/master/compiler/basicTypes/Lexeme.hs#L102 * okSymChar: https://github.com/ghc/ghc/blob/master/compiler/basicTypes/Lexeme.hs#L215 * notFollowedBySymbol: https://github.com/ghc/ghc/blob/master/compiler/parser/Lexer.x#L904 These functions intend to identify characters that can appear in symbolic identifiers. They all have different implementations. Which one is right? Or is there a better way to do this operation? There are other questions in the ticket, but I can probably sort those out on my own. If you can help, ideally you will respond in the ticket itself. Many thanks! Richard

expanding type synonyms in error messages
by Ömer Sinan Ağacan 26 Jun '15

26 Jun '15

Hi all, While working with complex types with lots of arguments etc. errors are becoming annoying very fast. For example, GHC prints errors in this way: Expected type: <type without any synonyms> Actual type: <type with synonyms> Now I have to expand that synonym in my head to understand the error. I was wondering if implementing something like this is possible: In type error messages, GHC also prints types that are cleaned from type synonyms. Maybe something like this: Expected type: <type1> (without synonyms): <type1, synonyms are expanded> Actual type: <type2> (without synonyms): <type2, synonyms are expanded> If this is not always desirable for some reason, we can hide this behavior behind a flag. What do GHC devs think about this? Is this, in theory, possible to do? How hard would it be to implement this? Thanks.
