appended to a path string that didn't end in a slash, yielding invalid
path names.

exist but just return false instead.

1. Use isValid() to check validity of the resulting path name in the
   eraseSuffix even though we can't think of a case where eraseSuffix could
   possibly cause an invalid path name.
2. Rewrite isValid() to not use the deprecated realpath function any more.
   It now just uses isascii to make sure all the characters are legit.

This chagne just renames some sys::Path methods to ensure they are not
misused. The Path documentation now divides methods into two dimensions:
Path/Disk and accessor/mutator. Path accessors and mutators only operate
on the Path object itself without making any disk accesses. Disk accessors
and mutators will also access or modify the file system. Because of the
potentially destructive nature of disk mutators, it was decided that all
such methods should end in the work "Disk" to ensure the user recognizes
that the change will occur on the file system. This patch makes that
change. The method name changes are:

makeReadable        -> makeReadableOnDisk
makeWriteable       -> makeWriteableOnDisk
makeExecutable      -> makeExecutableOnDisk
setStatusInfo       -> setStatusInfoOnDisk
createDirectory     -> createDirectoryOnDisk
createFile          -> createFileOnDisk
createTemporaryFile -> createTemporaryFileOnDisk
destroy             -> eraseFromDisk
rename              -> renamePathOnDisk

These changes pass the Linux Deja Gnu tests.

Get rid of the difference between file paths and directory paths. The Path
class now simply stores a path that can refer to either a file or a
directory. This required various changes in the implementation and interface
of the class with the corresponding impact to its users. Doxygen comments were
also updated to reflect these changes. Interface changes are:

appendDirectory -> appendComponent
appendFile -> appendComponent
elideDirectory -> eraseComponent
elideFile -> eraseComponent
elideSuffix -> eraseSuffix
renameFile -> rename
setDirectory -> set
setFile -> set

Changes pass Dejagnu and llvm-test/SingleSource tests.

llvm-svn: 22349

Change interface to Path class:
readable -> canRead
writable -> canWrite
executable -> canExecute

More (incremental) changes coming to close 495.

configure seems to find it on Cygwin but linking against it fails.

Standardize the error messages to be in "path: what failed: why" format.
Also attempt to use the correct errno to ThrowErrno in situations where
the errno value is erased by subsequent system calls.

gdb debugger doesn't get confused on which file it is reading (the one in
lib/System or the one in lib/System/{Win32,Unix})

* Ensure #includes are wrapped with appropriate HAVE_ guards
* Ensure variations in "dirent" structure are accounted for.

llvm-svn: 19158

Merge implementations of isValid and GetTemporaryDirectory into this file. There
is not any point having the operating system specific files for such little
variation between the Unix family of systems.

llvm-svn: 19134

llvm-svn: 19079

* llvm/Config/alloca.h already #includes config.h
* Minor readability/stylistic changes

llvm-svn: 19048

const because they affect the file system, not the Path object.

llvm-svn: 18973

because LLVM should be agnostic to the needs of specific front ends.

createTemporaryFile semantics where it doesn't create a fully unique name
if the basename doesn't exist. This functionality is now optionally
provided by the boolean reuse_current parameter to createTemporaryFile and
makeUnique. The default values differ because of the way these functions
are used in LLVM.

llvm-svn: 18961

* Fix implementation and documentation about LLVMGCCDIR/bytecode-libs
* Add the makeUnique method, replacement for getUniqueFilename in Support.
* Add the sys::CopyFile function, replacement for CopyFile in Support.
* Move GetLLVMConfigDir() into generic code area since its generic.

llvm-svn: 18947

Implement three new functions to allow setting access/permission bits on
the file referenced by a path. The makeReadable and makeExecutable methods
replace the FileUtilities MakeFileReadable and MakeFileExecutable
functions. The makeWritable function is new and provided for consistency
since Path has a writable() method.

llvm-svn: 18907

properly (examples: "", ".", "a").

llvm-svn: 18883

* Correct the std::string constructor to take a const reference.

llvm-svn: 18877

* Remove IsLibrary and GetLibraryPath, replaced by FindLibrary in ../Path.cpp \
* Implement GetSystemLibraryPaths and GetBytecodeLibraryPaths, instead of the \
  GetSystemLibraryPath1 and GetSystemLibraryPath2 methods

llvm-svn: 18862

* Don't use variable length arrays (replaced with alloca)

llvm-svn: 17901

* Clean up the StatusInfo constructor to construct all members and give
  them reasonable values.
* Get rid of the Vector typedef and make the interface to
  getDirectoryContent use a std::set instead of a std::vector so the dir
  content is sorted.
* Make the getStatusInfo method const and not return a useless boolean.

llvm-svn: 17872

returnn false if the file doesn't exist rather than throw ane exception.

llvm-svn: 17809

* Implement getDirectoryContents * Implement getStatusInfo * Implement setStatusInfo * Implement renameFile

llvm-svn: 17780

* Implement createTemporaryFile for mkstemp(3) functionality
* Fix isBytecodeFile to accept llvc magic # (compressed) as bytecode.
