ANNOUNCE: ioctl 0.0.1
by Maciej Piechotka 13 Sep '15

13 Sep '15

A package for type-safe I/O control. Currently only ioctl is supported. Currently simply a extract from my tuntap fork TODO: - Return the integer as well as structure (will break the API) - Port for Windows Network.Socket.IOCtl (as soon as I manage to setup some sane environment on this platform) - Wrapping around DeviceIoControl Example (in hsc): data NotRead = NotRead instance NotRead Int where ioctlReq _ = #const FIONREAD notRead s = ioctlsocket' s NotRead Regards

ANNOUNCE: Haskell Platform 7.10.2
by Mark Lentczner 31 Jul '15

31 Jul '15

Haskellers, we are pleased to announce the release of Haskell Platform 7.10.2 *get it here... <https://www.haskell.org/platform/>* Highlights include: - GHC 7.10.2 - packages & tools bumped to very latest - major package updates to: - attoparsec - case-insensitive - cgi - GLUT, GLURaw, OpenGL, & OpenGLRaw - mtl - network - primitive & vector - QuickCheck - random - syb - text - new website - new installer script for linux - 10 bugs closed: Issues · haskell/haskell-platform <https://github.com/haskell/haskell-platform/issues?utf8=%E2%9C%93&q=is%3Acl…> This is our first release concurrent with GHC's release. You'll notice that the version number has changed to reflect that from now on, our aim is to keep HP releases sync'd to GHC releases. *Note:* Haskell Platform download pages are often cached - you may need to hit reload to see the release. *About the last minute update to text package:* *tl;dr: Vast majority of code will never notice the difference. Go ahead and get the HP now and start enjoying 7.10.2 You can always update to the point release when it comes out.* Despite all the testing, GHC central noticed just a day before release that there was a regression with text literals in 7.10.2. It was possible to work around the issue via a change to the text package, and text-1.2.1.3 was released just today. Alas, there wasn't enough time to re-build and test the platform installers between then and now, so this release has text-1.2.1.1. There will be a point release (7.10.2.1) of the Platform this weekend or next with the updated text package. The issue does not result in incorrect code, only slow compilation times for very text literal laden code (as in thousands of literals), and slightly higher one-time construction cost at run-time. In full stack builds and many other test builds, these slow downs were inconsequential. *Windows Notes:* The Haskell Platform on Windows now provides the MSys2 tools. These tools are needed when installing packages that use conf-tools (generally rare). These tools are not automatically placed onto the PATH in order avoid troubles due to MSys2 tools which have the same name as a standard Windows tool (e.g., echo, find, dir). - Mark "release monad" Lentczner Special thanks to Erik Rantappa, Wasif Hasan Baig, & Ben Gamari for the new web site. Randy Polen for Windows build wrangling.

There ended up being a bit of timing skew between the Platform and GHC releases but an approximately concurrent release is still the plan. The Platform folks are hard at work as we speak, in the final stages of pushing out their release. I expect it will be announced shortly. Unfortunately due to the late notice of the text issue, the initial release will ship with text-1.2.1.1, which is still affected by the rewrite issue. That being said, the impact of this issue is mostly on compile time, in most cases you shouldn't see much impact on runtime performance. Moreover, they will be working to push out another release with text-1.2.1.3 in the coming days. Cheers, - Ben

I think the right place to ask this is libraries(a)haskell.org. I would imagine they're in final testing and/or getting release packages in place. (Note as previously mentioned that "text" was just updated, and the Platform needs that; this presumably means they had to start over making release packages.) -- brandon s allbery kf8nh sine nomine associates allbery.b(a)gmail.com ballbery(a)sinenomine.net unix, openafs, kerberos, infrastructure, xmonad http://sinenomine.net

ANNOUNCE: GHC version 7.10.2

30 Jul '15

===================================================================== The (Interactive) Glasgow Haskell Compiler -- version 7.10.2 ===================================================================== The GHC Team is pleased to announce a new bug-fix release of GHC, 7.10.2. There have been a number of significant bug fixes since the 7.10.1 (with over 70 defects fixed). These include fixes affecting type-checker correctness, runtime stability, and compiler performance. For this reason we highly recommend that users of 7.10.1 upgrade quickly. Note that due to changes made in this release to GHC's optimizer, previously fragile-but-working rewrite rules may fail to fire. One example of this was found in the widely-used `text` package late in the release cycle, which manifested in long compilation times and poor code generation for `Text` literals (see [Trac #10528]). Users are advised to use text >=1.2.1.2 which includes more robust rewrite rules. The full release notes including a complete listing of the changes in this release can be found here, https://downloads.haskell.org/~ghc/7.10.2/docs/html/users_guide/release-7-1… [Trac #10528]: https://ghc.haskell.org/trac/ghc/ticket/10528 How to get it ~~~~~~~~~~~~~ Both binary and source tarballs of GHC itself are available on the release download page, https://www.haskell.org/ghc/download_ghc_7_10_2 For a more smoother, better integrated experience users are encouraged to find a Haskell distribution. While these alternatives may not yet include 7.10.2, they offer tools and libraries to quickly get users up and running, as well as potentially better integration with the host operating system and package manager. See, https://www.haskell.org/downloads for more details. Background ~~~~~~~~~~ Haskell is a standard lazy functional programming language. GHC is a state-of-the-art programming suite for Haskell. Included is an optimising compiler generating good code for a variety of platforms, together with an interactive system for convenient, quick development. The distribution includes space and time profiling facilities, a large collection of libraries, and support for various language extensions, including concurrency, exceptions, and foreign language interfaces (C, whatever). GHC is distributed under a BSD-style open source license. A wide variety of Haskell related resources (tutorials, libraries, specifications, documentation, compilers, interpreters, references, contact information, links to research groups) are available from the Haskell home page (see below), https://www.haskell.org/ Supported Platforms ~~~~~~~~~~~~~~~~~~~ The list of platforms supported by GHC and the people responsible for them can be found here, https://ghc.haskell.org/trac/ghc/wiki/Platforms https://ghc.haskell.org/trac/ghc/wiki/CodeOwners Ports to other platforms are possible with varying degrees of difficulty. The Building Guide describes how to go about porting to a new platform: https://ghc.haskell.org/trac/ghc/wiki/Building Developers ~~~~~~~~~~ If you enjoy using GHC, you will likely also enjoy contributing to it! We are always looking for new contributors. Instructions on accessing our source code repository, and getting started with hacking on GHC, are available from the GHC developer site, https://ghc.haskell.org/trac/ghc/ Mailing lists ~~~~~~~~~~~~~ We run mailing lists for GHC users and bug reports; to subscribe, use the web interfaces at https://www.haskell.org/mailman/listinfo/glasgow-haskell-users https://www.haskell.org/mailman/listinfo/glasgow-haskell-bugs There are several other haskell and ghc-related mailing lists on www.haskell.org; for the full list, see https://www.haskell.org/mailman/listinfo/ Some GHC developers hang out on #haskell on IRC, too: https://www.haskell.org/haskellwiki/IRC_channel Please report bugs using our bug tracking system. Instructions on reporting bugs can be found here: https://www.haskell.org/ghc/reportabug Hashes & Signatures ~~~~~~~~~~~~~~~~~ In https://downloads.haskell.org/~ghc/7.10.2/ you will find a signed copy of the SHA256 hashes for the tarballs, using my GPG key, Benjamin Gamari <ben(a)well-typed.com> Fingerprint: FFEB 7CE8 1E16 A36B 3E2D ED6F 2DE0 4D4E 97DB 64AD
