[Improve handling of newtypes (fixes Trac 1495)
[EMAIL PROTECTED]
In a few places we want to "look through" newtypes to get to the
representation type. But we need to be careful that we don't fall
into an ininite loop with e.g.
newtype T = MkT T
The old mechansim for doing this was to have a field nt_rep, inside
a newtype TyCon, that gave the "ultimate representation" of the type.
But that failed for Trac 1495, which looked like this:
newtype Fix a = Fix (a (Fix a))
data I a = I a
Then, expanding the type (Fix I) went on for ever.
The right thing to do seems to be to check for loops when epxanding
the *type*, rather than in the *tycon*. This patch does that,
- Removes nt_rep from TyCon
- Make Type.repType check for loops
See Note [Expanding newtypes] in Type.lhs.
At the same time I also fixed a bug for Roman, where newtypes were not
being expanded properly in FamInstEnv.topNormaliseType. This function
and Type.repType share a common structure.
Ian, see if this merges easily to the branch
If not, I don't think it's essential to fix 6.8

As well as fixing the immediate problem (Trac #1972) this patch does
a signficant simplification and refactoring of pattern renaming.
Fewer functions, fewer parameters passed....it's all good. But it
took much longer than I expected to figure out.
The most significant change is that the NameMaker type does *binding*

Simon Marlow <[EMAIL PROTECTED]>**20071206084556
We were building a mapping from ModuleName to [Occ] from the usage

very poor naming decision, usg_mod is actually the module version, not
the ModuleName. usg_name is the ModuleName. Since Version is also an
instance of Uniquable, there was no type error: all that happened was
lookups in the map never succeeded. I shall rename the fields of
Usage in a separate patch.
This doesn't completely fix #1959, but it gets part of the way there.

[Improve eta reduction, to reduce Simplifier iterations
[EMAIL PROTECTED]
I finally got around to investigating why the Simplifier was sometimes
iterating so often. There's a nice example in Text.ParserCombinators.ReadPrec,
which produced:
NOTE: Simplifier still going after 3 iterations; bailing out. Size = 339
NOTE: Simplifier still going after 3 iterations; bailing out. Size = 339
NOTE: Simplifier still going after 3 iterations; bailing out. Size = 339
No progress is being made. It turned out that an interaction between
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.
I also discovered a missing side condition in the same equation, so fixing
that is good too. Now there is no loop when compiling ReadPrec.
Should do a full nofib run though.

It used to be a synonym for ":r" in 6.6.1, but this wasn't documented or
known about by the developers. In 6.8.1 it was accidentally broken.
This patch brings it back, but as "repeat the last command", similar to
pressing enter in gdb. This is almost as good for people who want it to
reload, and means that it can also be used to repeat commands like :step.

[EMAIL PROTECTED]
Adopt Trac #1537. The patch ended up a bit bigger than I expected,
so I suggest we do not merge this into the 6.8 branch. But there
is no funadamental reason why not.
With this patch, rebindable do-notation really does type as if you
had written the original (>>) and (>>=) operations in desguared form.
I ended up refactoring some of the (rather complicated) error-context
stuff in TcUnify, by pushing an InstOrigin into tcSubExp and its
various calls. That means we could get rid of tcFunResTy, and the
SubCtxt type. This should improve error messages slightly
in complicated situations, because we have an Origin to hand
to instCall (in the (isSigmaTy actual_ty) case of tc_sub1).
Thanks to Pepe for the first draft of the patch.

[Move file locking into the RTS, fixing #629, #1109
Simon Marlow <[EMAIL PROTECTED]>**20071120140859
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).

for now. If you say something else, the error messages are helpful.

[Attempt at fixing #1873, #1360
Simon Marlow <[EMAIL PROTECTED]>**20071116152148
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}.
