[Don't pass cc-options to Haskell compilations

misuse of cc-options.

[Don't propagate cc-options to the InstalledPackageInfo
Simon Marlow <marlowsd(a)gmail.com>**20080821132551
cc-options is for options to be passed to C compilations in the
current package. If we propagate those options to the
InstalledPackageInfo, they get passed to C compilations in any package
that depends on this one, which could be disastrous. I've seen
cc-options like these:
cc-options: -optc-std=c99
cc-options: -D_FILE_OFFSET_BITS=64
Cc-options: -Wall
these are all clearly intended to be local, but are in fact currently
propagated to all dependent packages.

Simon Marlow <marlowsd(a)gmail.com>**20080811173016
Now when using CPP you get
MIN_VERSION_<package>(A,B,C)

<package> in use is >= A.B.C, using the normal ordering on version
numbers.
This is done by auto-generating a header file

running CPP.

[Add an "exposed" field to the .cabal file library section
Duncan Coutts <duncan(a)haskell.org>**20080730164516
It's a bool flag that says if by default the library should
be registered with the compiler as exposed/unhidden (for
compilers which have such a concept, ie ghc). You might want
to do this for packages which would otherwise pollute the
module namespace or clash with other common packages.

[Fix the semantics of the simple file globbing to be sane
Duncan Coutts <duncan(a)haskell.org>**20080729152624
I realised when I started to document it that the behaviour
was not terribly consistent or sensible. The meaning now is:
The limitation is that * wildcards are only allowed in
place of the file name, not in the directory name or
file extension. In particular, wildcards do not include
directories contents recursively. Furthermore, if a
wildcard is used it must be used with an extension, so
"data-files: data/*" is not allowed. When matching a
wildcard plus extension, a file's full extension must
match exactly, so "*.gz" matches "foo.gz" but not
"foo.tar.gz".
The reason for providing only a very limited form of wildcard
is to concisely express the common case of a large number of
related files of the same file type without making it too easy
to accidentally include unwanted files.

[Use "pkg == 1.2.*" as the version wildcard syntax
Duncan Coutts <duncan(a)haskell.org>**20080729151612
Rather than "pkg ~ 1.2.*". This seemed to be the consensus.
The syntax "pkg == 1.2.*" means "pkg >= 1.2 && < 1.3" and it
is to encourage people to put upper bounds on api versions.

[Pass -no-user-package-conf to ghc when not using UserPackageDB

emptyBuildInfo is always added to and not replaced like we did
previously. That's not what we want in this case. We want to use '.'
for hsSourceDirs *only* if hsSourceDirs is otherwise null. As it
happens, due to the way the configurations code works, we're already
filling in the default if it'd otherwise be null so we do not need
'.' in the emptyBuildInfo at all.

Otherwise it can (and does) really confuse people.
The problem is that the command $ ghc-pkg-6.9 describe '*' --user

any other kind of failure from ghc-pkg.

For bool valued flags we were always producing the command line

It is important for cabal-install to be able to take an empty set

Secondly, with the orgininal algorithm it was possible to satisfy the

Previously we only checked the "cabal-version" field after parsing

[Fix names of profiling libs
Duncan Coutts <duncan(a)haskell.org>**20080407013449
I broke this recently when refactoring. Restore the original behaviour.
Was generating "libHSfoo_p-1.0.a" when it should be "libHSfoo-1.0_p.a".

Warning: The 'buildable' field is case sensitive, use 'True' or 'False'.

Duncan Coutts <duncan(a)haskell.org>**20080327221632
It's a bit more consistent.

[We do not show the field value on a parse error so don't pretend we do.
Duncan Coutts <duncan(a)haskell.org>**20080327221442
Drop the trailing ": " on the error message. We could provide the field
value but they're often multi-line and we cannot pin-point where the
error is exactly.

[Use the Text Bool instance for parsing literals in conditions
Duncan Coutts <duncan(a)haskell.org>**20080327215501
Since it exactly matches what the previous condition parser did.
So we have two different ways of parsing Bool depending on
context. Sigh. Both match exactly what was done in Cabal-1.2.

[Parse Bool fields using more cunning, allow new parses with a warning
Duncan Coutts <duncan(a)haskell.org>**20080327213411
We want to allow case-insensitive parsing however we don't want
packages being uploaded to hackage that will break older versions of
Cabal. If we allow new valid parses then we will end up breaking
stuff. So what we really want to do is allow new parses but warn if
they're not ones that older versions of Cabal would have allowed. So
long as hackage rejects pakcages that have parse warnings then we can
prevent new .cabal files appearing on hackage that would break older
Cabal versions. Our current parser (ReadP) does not support warnings
so we have to handle the bool fields specially in the parser wrapper
layer that we added to handle errors and warnings. This can go away
when we use a parser with support for error and warning messages.

[Add scripts for testing compatability with hackage packages
Duncan Coutts <duncan(a)haskell.org>**20080327161540
So far just a test that all the non-trivial Setup.(l)hs scripts
compile. This only tests the latest versions, though if one were
to download a complete archive then one could test them all.
To speed up the check we skip Setup.hs scripts that have fewer
than 22 words. Below this cutoff there are no custom hooks and
it catches the great majority of scripts which greatly speeds up
the check.

[Rename various *Verbose fields to *Verbosity instead
Duncan Coutts <duncan(a)haskell.org>**20080327034815
Despite appearances this is actually not completely pointless.
For the Cabal-1.4 branch we need the *Verbose fields to have the
same types as they did in Cabal-1.2, becuase lots of Setup.hs
scripts use them and our change to make them all have type Flag
makes many Setup.hs scripts fail. A solution for the 1.4 branch
is to rename the real field and to add the old field back in.
To keep as much similarity as possible between the HEAD and 1.4
branches I'm applying the name change in both.
On the plus side it's a better name anyway.

[Make UTF-8 decoding errors in .cabal files non-fatal
Duncan Coutts <duncan(a)haskell.org>**20080327031740
Previously we checked for invalid UTF-8 in the first phase of the
parser, which splitting the file up into nested sections and fields.
This meant the whole parser falls over if there is invalid UTF-8
anywhere in the file. Sadly there are already packages on hackage
with invalid UTF-8 so we would fail when parsing the hackage index.
The solution is to move the check into the parsing of the individual
fields and making it a warning not an error. We most typically get
invalid UTF-8 in free text fields like author name, copyright,
description etc so this should work out ok usually.
We now get pretty decent error messages, like:
Warning: hsx.cabal:5: Invalid UTF-8 text in the 'author' field.
The warning type is now structured so that hackage will be able to
distinguish general non-fatal warnings from UTF-8 decoding problems
which really should be fatal errors for package uploads.

[Separate the OS/Arch classifiation used for different purposes
Duncan Coutts <duncan(a)haskell.org>**20080327005321
We have to classify System.Info.{os,arch} strings into the OS and Arch
enums. For that purpose we have to be quite permissive since there are
lots of ailases that the various Haskell implementations use. However
for parsing os and arch names in .cabal files we'd prefer to use
canonical names, though we do have to allow the couple aliases already
in common use.
]
[Arch and OS names were previously allowed to contain "_-", restore that.
Duncan Coutts <duncan(a)haskell.org>**20080327004631
That is the arch and os strings in conditionals in .cabal files, like:
if arch(x86_64)
Previously the parser used isAlphaNum c || (c `elem` "_-"). This is
crucial for arch names like "x86_64". So make the new parser for OS
and Arch types use the same string parser as before (there is a string
parse part and a separate classification of known OS/Arch values).
