Time files... and here's another alpha HP for 7.10

So - I hear from a bird that 7.10.2 might be just around the corner. I'm getting ahead of the curve! I just did a fully hermetic and clean build of head of GHC 7.10 branch (what should become 7.10.2), and then brought HP up-to-date: - bootstrapped with 7.10.1 (so hptool needed fixes to build with that) - uses latest shake - built on a clean Debian Wheezy (7) install, (hence uses glibc 2.13 and should also run on Ubuntu 12.04 and later) The package versions are updated as follows: Cabal 1.22.2.0 --> 1.22.3.0 cabal-install 1.22.2.0 --> 1.22.4.0 attoparsec 0.12.1.4 --> 0.13.0.0 syb 0.4.4 --> 0.5.1 text 1.2.0.4 --> 1.2.1.1 cgi 3001.2.2.1 --> 3001.2.2.2 network 2.6.0.2 --> 2.6.2.0 network-uri 2.6.0.1 --> 2.6.0.3 QuickCheck 2.8 --> 2.8.1 hscolour 1.22 --> 1.23 GLUT 2.7.0.0 --> 2.7.0.1 GLURaw 1.5.0.0 --> 1.5.0.1 OpenGL 2.12.0.0 --> 2.12.0.1 OpenGLRaw 2.4.1.0 --> 2.5.0.0 Only package issue was: zlib 0.5.4.2 -- held back because cabal-install needs < 0.6 All the same caveats and notes from Alpha 2 still apply. All these changes are in the pre-release-2 branch on github -- I'll merge it all together later this week. There is a hp-bindist-tarball on my server: haskell-platform-7.10.1.20150528-x86_64-unknown-linux-deb7.tar.gz <http://www.ozonehouse.com/mark/platform/haskell-platform-7.10.1.20150528-x8…> SHA-256: b503c9e2c34c0865b5fee39444027667bb39b786fa7664029287e3bbf33379da I'll build and put up OS X version in a day or two. One last thing... I'm proposing that we name this release: Haskell Platform 7.10.2 ! - Mark

[directory] status of HsDirectory.h
by Phil Ruffwind 01 Jun '15

I noticed that there aren't many things left in the HsDirectory.h: - macros from autoconf - __hscore_long_path_size - __hscore_S_IRUSR/IWUSR/IXUSR/IFDIR Most of these could be done easily using hsc so I was tempted to remove them. Not to mention, the implementation of __hscore_long_path_size is rather dangerous on systems where PATH_MAX is not defined.[1] However, I wonder if the __hscore prefix has any significance. Are these functions by any chance used in GHC internals or some other libraries? For now I intend to leave them as is. But if no-one else uses them, then I think the header should be deprecated and made private in the future. [1]: http://pubs.opengroup.org/onlinepubs/9699919799 -- Phil

cabal-install: bug and quest for a workaround
by Wolfgang Jeltsch 01 Jun '15

01 Jun '15

Hi, I have just installed GHC 7.10.1 and cabal-install 1.22.4.0. The problem is that cabal-install often hangs when trying to download a package. With --verbose=3, I see that it gets a “301 Moved Permanently” from the server, tries to redirect, shows “Recovering connection to hackage.haskell.org”, and then hangs. Is there anything I can do to work around this issue? At the moment, I cannot work with my new GHC installation, since it is virtually impossible to install packages with cabal-install. All the best, Wolfgang
