@bringert bringert Rewrote the package dependency analysis code.
It is now about half as much code, and uses fewer and simpler
functions and data types. The external interface is now much smaller,
which meant that I had to change quite a bit of other code.
I orignally wrote this in parallel with dons' clean-up changes,
and had to merge by hand since darcs went into mad exponential conflict mode.
I hope I didn't revert too many of dons' changes.

@bringert bringert Changed zlib >= 0.4 to zlib >= 0.3. 0.3 works fine for me, and 0.4 is…

@bringert bringert Handle -fflag options. 0dec512
@bringert bringert Changed finalization to say that all installed and available packages…

@dcoutts dcoutts Don't report errors on cleaning when it's already clean

@bringert bringert Removed mtl and unix dependencies, they don't seem to be required. 266e26b
@bringert bringert The ConfigFlags now contain two different sets of install dirs, one f…
…or global and one for user installs.

This simplifies the install dirs handling a lot, and allows the user to specify both user and global install dirs in the config file, and chose installation type on the command line.
We now ignore the config file and command-line compiler flavor when choosing install directories, since that
is so messy. This might break installs with Hugs, but that requires testing.
The old code didn't work when the compiler was specified on the command-line anyway.

@bringert bringert Moved the local package index reading to a new module, Hackage.Index. b80e7e5
@dcoutts dcoutts Parse multiple repo urls listed in the .cabal/config correctly
The url part cannot contain any chars, since then we allow spaces and ',' and
thus break parsing of following repos.

@dcoutts dcoutts Make package searches ~100x faster but less featurefull
Instead of parsing every .cabal file in the package list (which is very slow)
We now just get the package name and version and do a case-insensitive
substring search on the package name. The output format remains unchanged.
So we no longer search inside package descriptions.

@dcoutts dcoutts It builds with HTTP-3001 as well. 86c9e31
@dcoutts dcoutts Fix handling of unadorned package names
ie make "cabal install xmonad" work ;-)
We were parsing unqalified package names as a dependency upon a specific but
empty version. That is treating "foo" as a dependency like "foo==".
We now treat unadroned package names as deps on any version.

@dcoutts dcoutts Read/write binary files using ByteString without .Char8 modules
ByteString.Char8 treats files as text files, which are really different
on windows. We were getting CRLF translation in Windows which was messing
everything up, like saving & reading the index file.
So now only use BS.Char8 where necessary.

@dcoutts dcoutts Replace command line handling
Use the new cabal command line handling infrastructure. Use proper flag types
rather than strings. 
Drop support for per-package command line flags as it was generally agreed to
be confusing.

@dcoutts dcoutts Significantly refactor configuration handling
ConfigFlags is not used in any of the modules that do the real work, instead
we just pass in the necessary information. Renamed ConfigFlags to SavedConfig
and moved it's definition into the Config module. Also change what information
is kept in the Repo type so that it knows the local path too. A PkgInfo now
also knows which Repo it is from.

The policy is encoded in the repo merge operation and in the various kinds of
lookup functions.

In preperation to add Hackage.LocalIndex module
a3b01f9
@dcoutts dcoutts Add Hackage.LocalIndex module as an index of installed packages
Very much like the RepoIndex module but only holds package ids at the moment
 rather that full InstalledPackageInfo records that we'd really prefer.
d705a32
@dcoutts dcoutts Update copyright and docs for RepoIndex
Added my copyright as I've almost completely rewritten the module.
3483739
@dcoutts dcoutts Change Dependency module to use the LocalIndex ADT
The whole Dependency module is pure now, no IO since it takes the indexes
as arguments, rather than the many more args required to do the IO to load
up the indexes. Much nicer. Also update all callers.
92613cd
@dcoutts dcoutts Remove unused listInstalledPackages, replaced by LocalIndex.read f29de85
@dcoutts dcoutts Add IndexUtils with functions to disambiguate packaage names
To allow us to implement case-insensitivity in package names given on the
command line. We lookup in the package index for packages with the same name
case-insensitively. If there is no exact match exact case-sensitively and
there are more than one packages matching case-insensitively then it aborts
with a message listing the matches. This should not often happen since within
any single HackageDB server, we can check that packages names are unique
case-insensitively but it's possible to get ambiguities if cabal-install has
been configured to use multiple repos.

@dcoutts dcoutts Treat package names given on the command line case insenitively

@dcoutts dcoutts Use a dependency graph rather than a list when installing packages
This allows us to figure out what to do when installing a single package
fails. Instead of just carrying on as if nothing had happened and then
failing several other packages which depended on the one that failed
initially we can cut those dependent packages out as soon as the first one
fails and if there is anything left that did not depend on the failed
package then we can try and carry on.

@dcoutts dcoutts Minor changes to the tar packing code
Use lazy bytestring when packing tar entry headers rather than strict and
then making a single chunk lazy bytestring later. The lazy bytestring pack
will only generate a single chunk for a String that short (<4k).
Use openBinaryFile rather than openFile + hSetBinaryMode.
Add a haddock module header with copyright note.

@dcoutts dcoutts Use relative paths when makeing tar.gz rather than changing current dir
The current directory is a global variable, we should not mutate it.
So instead, pass a base and relative path when generating tar entries.
Also change sanitizePath to be pure and use FilePath.Poisx.

@dcoutts dcoutts Simplify the tar code a bit more
We always know the base path for construction or extraction so don't
bother using Maybe FilePath. Also use GZip qualified.

@dcoutts dcoutts Record and report the exceptions that cause build failure
When installing a bunch of package we have to catch exceptions since
we carry on building other packages that did not depend on the
failing package. We were recording what phase the failure was in but
not the actual exception. We now record that too and print it along
with the more general explanation of what package failed and in
which phase. It's not perfect, eg when a package fails to compile we
end up printing that the exception was "ExitFailure 1" which is not
very useful.

@pepeiborra pepeiborra #223 part2: Support all the configure options in the config file
This patch takes advantage of the new OptionField structure in Distribution.Simple.Command
to provide support for all the configure command line options in the .cabal/config file.
This has a global effect on all the packages managed by cabal-install.

The ticket also mentions support for per-package sections in the config file. This patch
does not take care of that.

@dcoutts dcoutts Make ResolvedDependency an internal detail of dependency calculation
Externally we currently use a DepGraph, though we'll move to a InstallPlan.
This is a step towards making it easier to swap in different package
dependency resolution algorithms. Because we're hiding ResolvedDependency
we have to disable the extended Hackage.Info stuff for the moment.

@dcoutts dcoutts Add new InstallPlan type
This is joint work with Kolmodin.
An InstallPlan records what we want to install and records the outcome
of installing packages. It has a fairly strict internal invariant which

@dcoutts dcoutts Make the default SavedConfig contain empty rather than default Config…
…Flags

We do not want to pass a load of default command line flags. We only want
to pass flags where we're overriding the defaults.
Also it's because old Cabal versions do not understand new flags.
50d9a3d
@dcoutts dcoutts Simplify the way we derive configure, install and upgrade commands
so we do not accidentally inherit the default flags for the underlying
configure command when we in fact want the empty flags. I am beginning

@dcoutts dcoutts Add a new --cabal-lib-version flag to the install command
It's used to select which version of the Cabal lib to use when
configuring, building and installing packages. It's mainly so that
we can use cabal-install to help us test that packages build ok with
both old and new versions of the Cabal library. In particular we'd
like to check every package on hackage to make sure that new Cabal
versions are not breaking packages that worked with older versions.

@dcoutts dcoutts Convert the Install module to use the new SetupWrapper

@dcoutts dcoutts Generalise and rename PkgInfo to include local packages
Renamed to AvailablePackage since that what it is really.
Now instead of just representing packages from a remote hackage repo
it includes an alternative for a local unpacked package. In future
we should add more alternatives, eg for other local packages (ie not
just the one that's unpacked in the current dir) and for remote
packages in source control like darcs, git etc.
0d193ef
@dcoutts dcoutts Remove the resolveDependenciesLocal, implement it via resolveDependen…
…cies

The local variant was for the case that we were starting from a package
description rather than a dependency to a named package. In the local
case we not only need to resolve the dependencies of the package but also
to find a flag assignment for the local package. This case crops up in
the resolver normally when we try to satisfy a dependency, we have to
pick a flag assignment for the dependency and resolve its dependencies.
It is annoying to have both entry points, especially as we want the
resolver to be plugable. So instead we define the local package as an
available package, then by resolving a single dependency on exactly the
name and version of the local package then we can get an install plan for
the local package. It also requires generalising installPkg to deal with
the local case.

@dcoutts dcoutts Improve InstallPlan error checking and reporting
Instead of just reporting that a plan is invalid, produce a
detailed list of reasons why it is invalid.
This should be useful for people debugging dependency resolvers.
Also rename the complete property to closed, since the property
is about the set being closed under the dependency relation.
Also re-use the PackageIndex functions for checking the validity
conditions rather than re-implementing the checks locally.

@dcoutts dcoutts Packages are only invalid if they have more than zero problems. 11045f3
@dcoutts dcoutts Switch from DepGraph to InstallPlan
The dependency resolver has had to be extended in a slightly hacky
way to gather the extra information needed by an install plan. In
particular it requires the flags to use to configure each package,
the actual versions of dependencies to use and all of the
installed packages and their closure of dependencies.
However the current resolver is fairly naive and so can be easily
persuaded into producing an invalid install plan, in which case
you'll get a detailed list of reasons as to why it is invalid.

84de281
@dcoutts dcoutts Hide the installed instance when installing the local package.
Otherwise the dependency resolver may decide to pick the installed
instance of the package but we really do want to install the local

delete it from the installed package index.

@dcoutts dcoutts Reimplement InstallPlan.failed as it was completely wrong
It was finding all the dependencies of the failed package and

all the packages that depend on the failed package (the reverse
dependencies) and mark them as failed. We use the reverse
dependency Graph that we saved in the InstallPlan.

@dcoutts dcoutts Refactor installLocalPackage and installRepoPackages

generating plans now rather than doing the installation directly.

@dcoutts dcoutts Restructure the package installing code
Previously each layer called the next layer down and therefore the
top layer had to take all of the params that the bottom layer needed
even though they were mostly or wholly unmodified on the way down.
Now each layer takes the next layer as a parameter so we do not need
to take the params that are not used directly by the current layer.
The overall stack is then built by applying each layer to the next.

@dcoutts dcoutts Rewrite getUpgradableDeps so it's simpler and linear time
Also change so that instead of giving the available package with
the highest version number (where that is higher than the installed
package) it gives us a dependency on a version of the package that
is strictly greater than the one installed. This is more flexible
since when resolving we do not necessarily have to pick the very
latest version if that turns out not to be possible.

@dcoutts dcoutts Hide any available base and ghc-prim packages from the dep resolver
Previously if the base package was available on hackage then the dep

certainly technically impossible at the moment. So now since the dep
resolver does not see these available packages it cannot pick them.
This should fix ticket #174.

@dcoutts dcoutts First version of the top-down package dependency resolver
This is a new dependency resolver that produces valid install plans.
It works in polynomial time however because the search space is 
exponential in size it is not guaranteed to find a solution even if
one exists. It works by generating and then exploring the search
space represented as a lazy tree. It uses constraints to prune
choices and heuristics when guesses are necessary. Currently it can
generate install plans for 99% of the packages on hackage. The
remaining 6 packages should be doable with two extra tricks.
It is not finished and is not yet usable in practice.

0540367
@dcoutts dcoutts Switch DependencyResolver to return Progress and String errors
rather than Either and structured error type [Dependency]. The reason
we cannot use that as a structured error type any more is because
missing dependencies is not the only failure reason. There are
several reasons, several of which are pretty complex. For now we'll
have to do with a human readable message. Perhaps we may be able to
find a common structured type that the different dep resolvers can
all agree on. I'm not hopeful however as error reporting seems to be
closely tied to the dep resolution approach.

@dcoutts dcoutts Rearrange and tidy bits of the topdown resolver 7d078df
@dcoutts dcoutts As a heuristic, use topological order for the order of package choices
The general case in exploring the state space is that we have a set of
choices (package names) and for each choice we have a number of
versions of that package we could pick. If there's only one version of
a package then we make that choice first. Otherwise we have to pick
some package and select one of the available versions. The question is
which package should we make a choice for first? Previously we picked
completely arbitrarily. Surprisingly this actually works pretty well.
An improvement is to pick packages in topological order. This works
better because it allows dependencies from earlier choices to
constrain our later choices.

@dcoutts dcoutts Implement plan improvement
The idea is to improve the plan by swapping a configured package for
an equivalent installed one. For a particular package the condition
is that the package be in a configured state, that a the same version
be already installed with the exact same dependencies and all the
packages in the plan that it depends on are in the installed state.

@dcoutts dcoutts Fix improvePlan so the index is updated incrementally
It's important since later packages can depend on earlier ones having
been changed from configured to pre-existing. That is afterall the
whole point of considering them in reverse toplogical order.
Also, remove duplicates in the dependencies list of installed
packages since ghc-pkg does not currently prevent duplicates in (eg
multiple depends on the same version of base). See ghc bug #2230.

@dcoutts dcoutts Change the DependencyResolver type to take a per-package version pref
And add a few global package version pref policies and use them in
ordinary install and upgrade. For install we use a policy that says
that we prefer the latest version of a package that we specifically
request and prefer the installed version of any other package. For
upgrade we simple always prefer the latest version. One can imageine
other policies where we prefer the latest version for only some
interesting subset of packages and installed otherwise.
No resolvers actually make use of this preference yet.

Up to now 'upgrade' took no args and tried to upgrade all installed

a new mode rather like 'cabal install'. The difference is that with
$ cabal install foo
it means install latest version of foo but otherwise prefer the
installed versions of deps of foo, while
$ cabal upgrade foo
means install the latest version of foo and also the latest
versions of all the dependencies of foo.
