This prevents spawned process from assigning jobs to its own children. Suppose process A spawns process B. The B process has a job assigned (call it J1) and when it tries to spawn a new process C the C automatically inherits the job.

In fact this check is performed by gathering the internal tool dependencies of each component of the package according to this module, and ensuring those properties on each so-gathered dependency.version bounds and components of the package are unchecked.

The CopyToDb will adjust the paths to be relative to the provided package database when copying / installing.Cabal)The installation directories in terms of s that contain variables.The defaults for most of the directories are relative to each other, in particular they are all relative to a single prefix. This makes it convenient for the user to override the default installation directory by only having to specify --prefix=... rather than overriding each individually. This is done by allowing $-style variables in the dirs. These are expanded by textual substitution (see ).A few of these installation directories are split into two components, the dir and subdir. The full installation path is formed by combining the two together with /. The reason for this is compatibility with other Unix build systems which also support --libdir and  --datadir/. We would like users to be able to configure --libdir=/usr/lib64 for example but because by default we want to support installing multiple versions of packages and building the same package for multiple compilers we append the libsubdir to get: /usr/lib64/$libname/$compiler.An additional complication is the need to support relocatable packages on systems which support such things, like Windows.Cabal9The directories where we will install files for packages.We have several different directories for different types of files since many systems have conventions whereby different types of files in a package are installed in different directories. This is particularly the case on Unix style systems.Cabalforeign librariesCabal5Substitute the install dir templates into each other.To prevent cyclic substitutions, only some variables are allowed in particular dir templates. If out of scope vars are present, they are not substituted for. Checking for any remaining unsubstituted vars can be done as a subsequent operation.-The reason it is done this way is so that in  we can replace  with the  and get resulting s that still have the  in them. Doing this makes it each to check which paths are relative to the $prefix.CabalConvert from abstract install directories to actual absolute ones by substituting for all the variables in the abstract paths, to get real absolute path.CabalCheck which of the paths are relative to the installation $prefix.If any of the paths are not relative, ie they are absolute paths, then it prevents us from making a relocatable package (also known as a "prefix independent" package).Cabal Convert a  to a  including any template vars.Cabal7Convert back to a path, any remaining vars are includedCabal=The initial environment has all the static stuff but no pathscabal-devel@haskell.orgportableNoneCabalExtract the version number from the output of 'strip --version'.Invoking "strip --version" gives very inconsistent results.

The arguments are the name of the input file, the name of the output file and a verbosity level. Here is a simple example that merely prepends a comment to the given source file: ppTestHandler :: PreProcessor ppTestHandler = PreProcessor { platformIndependent = True, ppOrdering = \_ _ -> return, runPreProcessor = mkSimplePreProcessor $ \inFile outFile verbosity -> do info verbosity (inFile++" has been preprocessed to "++outFile) stuff <- readFile inFile writeFile outFile ("-- preprocessed as a test\n\n" ++ stuff) return ()We split the input and output file names into a base directory and the rest of the file name. The input base dir is the path in the list of search dirs that this file was found in. The output base dir is the build dir where all the generated source files are put.The reason for splitting it up this way is that some pre-processors don't simply generate one output .hs file from one input file but have dependencies on other generated files (notably c2hs, where building one .hs file may require reading other .chi files, and then compiling the .hs file may require reading a generated .h file). In these cases the generated files need to embed relative path names to each other (eg the generated .hs file mentions the .h file in the FFI imports). This path must be relative to the base directory where the generated files are located, it cannot be relative to the top level of the build tree because the compilers do not look for .h files relative to there, ie we do not use "-I .", instead we use "-I dist/build" (or whatever dist dir has been set by the user)Most pre-processors do not care of course, so mkSimplePreProcessor and runSimplePreProcessor functions handle the simple case.CabalThis function can reorder all modules, not just those that the require the preprocessor in question.

It is only the relative part that is preserved in the destination. For example: copyFiles normal "dist/src" [("", "src/Foo.hs"), ("dist/build/", "src/Bar.hs")]This would copy "src/Foo.hs" to "dist/src/src/Foo.hs" and copy "dist/build/src/Bar.hs" to "dist/src/src/Bar.hs".This operation is not atomic.

We pass to it two interfaces (one to check contents of packages, the other to inspect working tree for orphan files) and before that a Boolean to indicate whether we want pure checks or not. Based on these parameters, some checks will be performed, some omitted. Generality over m means we could do non pure checks in monads other than IO (e.g. a virtual filesystem, like a zip file, a VCS filesystem, etc).Cabal?Check for common mistakes and problems in package descriptions.This is the standard collection of checks covering all aspects except for checks that require looking at files within the package. For those see .CabalThis function is an oddity due to the historical GenericPackageDescription/PackageDescription split. It is only maintained not to break interface, use  if possible.CabalSanity check things that requires looking at files in the package. This is a generalised version of 7 that can work in any monad for which you can provide   operations.The point of this extra generality is to allow doing checks in some virtual file system, for example a tarball in memory.CabalSanity checks that require IO.  looks at the files in the package and expects to find the package unpacked at the given filepath.Cabal Same as , but working with .2This function is included for legacy reasons, use  if you are working with .Cabal checks. Remember that for historical quirks in the cabal codebase we have both  and  and that PD is both a *field* of GPD and a concept of its own (i.e. a fully realised GPD). In this case we are checking (correctly) GPD, so for target info/checks you should walk condLibrary_ etc. and *not* the (empty) target info in PD.
