Comment:
Fixed in bytestring:
{{{
Wed May 19 16:47:52 BST 2010 Simon Marlow <[email protected]>
* bump version to 0.9.1.7
Thu May 20 10:03:29 BST 2010 Simon Marlow <[email protected]>
* ROLLBACK: hGetContents: use hGet instead of hGetNonBlocking +
hWaitForInput + hIsEOF
This patch was based on a misconception about the semantics of
hGetBuf, and caused hGetContents to block more often than it should.
The change to documentation also caused additional confusion:
http://hackage.haskell.org/trac/ghc/ticket/4041
By rolling back we re-introduce the original bug (GHC bug #3808), but
That bug has a workaround (put the Handle in binary mode).
In the future we will fix the bug properly using hGetBufSome, see
http://hackage.haskell.org/trac/ghc/ticket/4046

* ROLLBACK partly: update docs for hGet, hGetNonBlocking
The change to the docs for hGet was incorrect. Leaving the change to
the hGetNonBlocking docs as it is a clarification.
