If I comment out that specific test, another test fails a few tests later. If I comment out that one, another one fails a few later. If I comment out *that* one... you get the picture. Running as administrator does not solve the permission denied issue. I am on Windows 8.1, if that matters. I think, I am not sure, that any test with expect_broken in them hangs without moving on. -- Ticket URL: <http://ghc.haskell.org/trac/ghc/ticket/8571> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler

[GHC] #8345: A more efficient atomicModifyIORef'

#8345: A more efficient atomicModifyIORef' ------------------------------------+------------------------------------- Reporter: parcs | Owner: Type: task | Status: new Priority: normal | Milestone: Component: libraries/base | Version: 7.6.3 Keywords: | Operating System: Unknown/Multiple Architecture: Unknown/Multiple | Type of failure: None/Unknown Difficulty: Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | ------------------------------------+------------------------------------- `atomicModifyIORef'` is currently defined as: {{{ #!haskell atomicModifyIORef' ref f = do b <- atomicModifyIORef ref (\x -> let (a, b) = f x in (a, a `seq` b)) b `seq` return b }}} This doesn't seem to be the best we can do, though. The following implementation exhibits a speedup of 1.7x (vanilla RTS) / 1.4x (threaded RTS) over the current implementation: {{{ #!haskell atomicModifyIORef' ref f = do b <- atomicModifyIORef ref $ \a -> case f a of v@(a',_) -> a' `seq` v b `seq` return b }}} The differences between this version and the current version are: 1. the lambda is now strict in `f a`, and 2. a new result tuple is no longer being allocated. Is there a good reason why `atomicModifyIORef'` is not already defined this way? -- Ticket URL: <http://ghc.haskell.org/trac/ghc/ticket/8345> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler

#8593: vector is being built even with `--no-dph` ------------------------------------+------------------------------------- Reporter: nomeata | Owner: Type: feature request | Status: new Priority: low | Milestone: Component: Build System | Version: 7.7 Keywords: | Operating System: Unknown/Multiple Architecture: Unknown/Multiple | Type of failure: None/Unknown Difficulty: Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | ------------------------------------+------------------------------------- I usually use `./sync-all --no-dph get` to speed up things a bit. But packages `vector`, `primitive` and `random` are still being pulled (by virtue of being submodules), and then built. It would be nice if the build system would build them only if `libraries/dph` is available, or have another way of making them optional.

When I run it on linux, it works perfectly, being part of the loop (write- read-write-read-...). On windows it receives only first msg from the other side (write-read- write-write-...). The packets are still going, although. Before that, I used the sockets directly; changing to HandleStream didn't help. The code is: {{{ transmit :: Int -> HandleStream ByteString -> ByteString -> IO [Bytestring] transmit delay sock packet = do let input = timeout delay $ sock `readBlock` 8 <* putStrLn "\nData was read!" sock `writeBlock` pack strings <- whileJust input return [str | Right str <- strings] whileJust action = do result <- action case result of Just a -> (:) <$> return a <*> whileJust action Nothing -> return [] }}} -- Ticket URL: <http://ghc.haskell.org/trac/ghc/ticket/8529> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler

The back-ported commits are on branches in my GHC GitHub repo: https://github.com/darinmorrison/ghc ghc-7.6.3-clang (just clang stuff) ghc-7.6.3-clang+mavericks (clang stuff + 10.9 fixes) I haven't tested this fully yet, or even compiled it yet with the latest changes, but I think I caught most of the stuff that might cause problems. (Actually I just tried now and there's another error further along I still need to track down.) There are a few other rough edges still: warnings, etc. Also, if you want to use the validate script, you'll need to turn off Werror. Anyway, I'll try to get remaining stuff sorted out and get some binaries up in the next couple of days. -- Ticket URL: <http://ghc.haskell.org/trac/ghc/ticket/8480> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler

#8251: Validate submodule references during pre-receive hook ------------------------------------+------------------------------------- Reporter: hvr | Owner: hvr Type: task | Status: new Priority: normal | Milestone: Component: None | Version: 7.6.3 Keywords: admin git | Operating System: Unknown/Multiple Architecture: Unknown/Multiple | Type of failure: None/Unknown Difficulty: Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | ------------------------------------+------------------------------------- Right now, you can push a commit introducing a not-yet existing Git submodule commit reference. However, such commits can be rejected for submodule repositories hosted at git.haskell.org, thus forcing the user to push the submodule first, and only after that push the submodule-affecting commit in ghc.git This kind of sanity checking ghc.git commits will become more important, if more repositories are converted into Git submodules. -- Ticket URL: <http://ghc.haskell.org/trac/ghc/ticket/8251> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler

[GHC] #8369: Small improvements to ./sync-all

#8369: Small improvements to ./sync-all ------------------------------------+------------------------------------- Reporter: nwf | Owner: Type: bug | Status: new Priority: lowest | Milestone: Component: Compiler | Version: 7.7 Keywords: | Operating System: Unknown/Multiple Architecture: Unknown/Multiple | Type of failure: None/Unknown Difficulty: Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | ------------------------------------+------------------------------------- ./sync-all get in a local clone does not use local submodules. That is, if I {{{ git clone ghc ghc-tmp; cd ghc-tmp; ./sync-all get }}} the contained clones come over just fine from ghc/... into ghc-tmp/..., but the submodules are fetched over the network connection. I think the attached patch brings the "fetch from the clone source if possible" behavior over to submodules, though possibly not in an ideal way. Separately, I find that I want to run shell commands in each repository; adding a "shell" verb is trivial and a second patch is attached. -- Ticket URL: <http://ghc.haskell.org/trac/ghc/ticket/8369> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler

#8070: Use a captcha for trac registrations ------------------------------------+------------------------------------- Reporter: igloo | Owner: Type: bug | Status: new Priority: high | Milestone: Component: None | Version: 7.6.3 Keywords: | Operating System: Unknown/Multiple Architecture: Unknown/Multiple | Type of failure: None/Unknown Difficulty: Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | ------------------------------------+------------------------------------- Use a captcha for trac registrations. These all seem to be 0.11-only: * http://trac-hacks.org/wiki/CaptchaAuthPlugin * http://trac-hacks.org/wiki/CaptchaAuthPlusPlugin * http://trac-hacks.org/wiki/SimpleCaptchaPlugin so the simplest answer might be recaptcha, although I believe that needs to be set up to be associated with a Google account: * http://trac-hacks.org/wiki/RecaptchaRegisterPlugin -- Ticket URL: <http://ghc.haskell.org/trac/ghc/ticket/8070> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler
