very poor naming decision, usg_mod is actually the module version, not
the ModuleName.  usg_name is the ModuleName.  Since Version is also an

lookups in the map never succeeded.  I shall rename the fields of

eta-expansion, casts, and eta reduction was responsible. The change is
small and simple, in SimplUtils.mkLam: do not require the body to be
a Lam when floating the cast outwards.

12 years agoMove file locking into the RTS, fixing #629, #1109
Simon Marlow [Tue, 20 Nov 2007 14:08:59 +0000 (14:08 +0000)]
Move file locking into the RTS, fixing #629, #1109
File locking (of the Haskell 98 variety) was previously done using a
static table with linear search, which had two problems: the array had
a fixed size and was sometimes too small (#1109), and performance of
lockFile/unlockFile was suboptimal due to the linear search.
Also the algorithm failed to count readers as required by Haskell 98
(#629).

Now it's done using a hash table (provided by the RTS).  Furthermore I
avoided the extra fstat() for every open file by passing the dev_t and
ino_t into lockFile.  This and the improvements to the locking
algorithm result in a healthy 20% or so performance increase for
opening/closing files (see openFile008 test).

FIX Trac #1825: standalone deriving Typeable

Standalone deriving of typeable now requires you to say
instance Typeable1 Maybe
which is exactly the shape of instance decl that is generated
by a 'deriving( Typeable )' clause on the data type decl.

This is a bit horrid, but it's the only consistent way, at least
for now.  If you say something else, the error messages are helpful.

Always do 'setup makefile' before building each library

Attempt at fixing #1873, #1360

I think I figured out a reasonable way to manage the GHCi context,
comments welcome.

Rule 1: external package modules in the context are persistent.  That
is, when you say 'import Data.Maybe' it survives over :load, :add,
:reload and :cd.

Rule 2: :load and :add remove all home-package modules from the
context and add the rightmost target, as a *-module if possible.  This
is as before, and makes sense for :load because we're starting a new
program; the old home-package modules don't make sense any more.  For
:add, it usually does what you want, because the new target will
become the context.

Rule 3: any modules from the context that fail to load during a
:reload are remembered, and re-added to the context at the next
successful :reload.

Claus' suggestion about adding the "remembered" modules to the prompt
prefixed with a ! is implemented but commented out.  I couldn't
decide whether it was useful or confusing.

One difference that people might notice is that after a :reload where
there were errors, GHCi would previously dump you in the most recent
module that it loaded.  Now it dumps you in whatever subset of the
current context still makes sense, and in the common case that will
probably be {Prelude}.
