[Haskell-cafe] Re: ANNOUNCE: happstack 0.5.0

[Michael Snoyman]

Hey Jeremy,

I see below that you included the experimental WAI support. I'm excited to try it out, but I don't see it in happstack-server (maybe I'm blind). Could you point it out?

Thanks,

Michael

Hello,

I am very pleased to announce Happstack 0.5.0. It should install cleanly from hackage via:

Âcabal install happstack

If it does not, please report errors to the happstack mailing list:

http://groups.google.com/group/HAppS

(You will, unfortunately, need to be subscribed due to SPAM issues).

Here are the official release notes:

Release Notes:

ÂÂThis release should fix many (hopefully all) known cabal install

ÂÂrelated issues. It also includes many other improvements detailed

ÂÂbelow.

Known issues:Â

ÂÂ* dropped support for GHC 6.8. GHC 6.10 and 6.12 currently supported.

ÂÂ* happstack-data compiled with -O0 due to bug in cabalÂ

ÂÂ Â http://thread.gmane.org/gmane.comp.lang.haskell.cafe/69215

ÂÂ Â You may be able to change that to -O2 if you first do:

ÂÂ

ÂÂ Â Â cabal install --reinstall syb-with-class --disable-documentation

ÂÂ Â But we need a solution that works automatically when people run, cabal install happstack.

Changes since 0.4.1:

ÂÂ* many IxSet improvements by Gracjan Polak

ÂÂ Â- hide IxSet constructor. use ixSet instead.

ÂÂ Â- improved efficiency of gteTLE, getGTE, and getRange

ÂÂ Â- get rid of Dynamic, just use Data.Typeable (internal change)

ÂÂ Â- added deleteIx

ÂÂ Â- Eq and Ord instances for IxSet

ÂÂ Â- removed a bunch of cruft

ÂÂ Â- greatly improved documentation

ÂÂ Â- added stats function

ÂÂ Â- Protect user from using unindexed keys in searches in IxSet

ÂÂ Â- Runtime safeguard for badly formed inferIxSet indexes

ÂÂ Â- Fixed IxSet Default instance

ÂÂ Â- More detailed error messages in IxSet

ÂÂ* work around bug in bytestring which causes the server to hang

ÂÂ Â(http://hackage.haskell.org/trac/ghc/ticket/3808)

ÂÂ* support for uincode Text and lazy Text types

ÂÂ Â- Serialize/Version instances now provided automatically by happstack-data

ÂÂ Â- instances of EmbedAsChild and EmbedAsAttr for Text for Identity,

ÂÂ Â ÂIdentityT, ServerPartT, and WebT.

ÂÂ Â- patches sent upstream to HSP, waiting on acceptance

ÂÂ* Added Serialize/Version instances for time / Data.Time library

ÂÂ* Improvements to GuestBook demo by Gracjan Polak

ÂÂ Â- better handling of Ctrl-C

ÂÂ Â- simplified .cabal to only build executable

ÂÂ* Improvements to GuestBook demo by Gracjan Polak

ÂÂ Â- nice command line interface with help message and version information

ÂÂ Â- restructured parsing of command line to make it scale better with

ÂÂ Â Âfurther parameters

ÂÂ Â- added reference to Paths_guestbook module to enable incorporating version

ÂÂ Â Âand path information generated by cabal.

ÂÂ Â- added withLogger transformer guaranteeing clean setup and

ÂÂ Â Âteardown of loggers

ÂÂ Â- Added clean shutdown to logging component.

Â

ÂÂ* fail instance for WebT now includes location of pattern match failure. e.g.

ÂÂ Â Âsrc\AppControl.hs:43:24: Pattern match failure in do _expression_

ÂÂ* added expireCookie function

ÂÂ* Improvements to documentation

ÂÂ* Additional test cases

ÂÂ* Fixes many build failures

ÂÂ* Experimental: Added proof of concept port of happstack-server to WAI.Â

ÂÂ Âhttp://www.haskell.org/pipermail/haskell-cafe/2010-March/074142.html

ÂÂ* added 'dirs' guard. (Similar to dir, but for a list of path

ÂÂ Âcomponents).

ÂÂ* set SO_KEEPALIVE so that dropped connections will eventually time out

ÂÂ* happstack-util only depends on QuickCheck when compiled with

ÂÂ Â-ftests. This is wrong but solves a lot of annoy install failures.

ÂÂ* file serve functions now use MonadPlus instead of setting explicit 404

ÂÂ* XMLMetaData for webHSP

ÂÂ* Allow colons in cookie names
