2013-03-14[Support] Fix lifetime of file descriptors when using MemoryBuffer.Michael J. Spencer
Clients of MemoryBuffer::getOpenFile expect it not to take ownership of the file descriptor passed in. So don't. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@176995 91177308-0d34-0410-b5e6-96231b3b80d8

infinite loop by constantly trying to create the parent path. This can happen if the path is a relative filename and the current directory was removed. Thanks to Daniel D. for the hint in fixing it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@176226 91177308-0d34-0410-b5e6-96231b3b80d8

2012-11-30Switch LLVM_USE_RVALUE_REFERENCES to LLVM_HAS_RVALUE_REFERENCES.Chandler Carruth
Rationale: 1) This was the name in the comment block. ;] 2) It matches Clang's __has_feature naming convention. 3) It matches other compiler-feature-test conventions. Sorry for the noise. =] I've also switch the comment block to use a \brief tag and not duplicate the name. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@168996 91177308-0d34-0410-b5e6-96231b3b80d8
2012-11-15PathV2: Fix a possible infinite loop.Daniel Dunbar
- The code could infinite loop trying to create unique files, if the directory containing the unique file exists, but open() calls on non-existent files in the path return ENOENT. This is true on the /dev/fd filesystem, for example. - Will add a clang side test case for this. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@168081 91177308-0d34-0410-b5e6-96231b3b80d8

2012-06-02Use access(2) instead of stat(2) to check if a file exists.Benjamin Kramer
Apart from being slightly cheaper, this fixes a real bug that hits 32 bit linux systems. When passing a file larger than 2G to be linked (which isn't that uncommon with large projects such as WebKit), clang's driver checks if the file exists but the file size doesn't fit in an off_t and stat(2) fails with EOVERFLOW. Clang then says that the file doesn't exist instead of passing it to the linker. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@157891 91177308-0d34-0410-b5e6-96231b3b80d8

2012-05-05[Support] Rewrite sys::fs::unique_file to not be stupid with /dev/urandom.Daniel Dunbar
- Just use sys::Process::GetRandomNumber instead of having two poor implementations. - This is ~70 times (!) faster on my OS X machine. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@156238 91177308-0d34-0410-b5e6-96231b3b80d8
2012-04-23Conflict with st_dev/st_ino identifiers under Debian GNU/HurdSylvestre Ledru
The problem is that the struct file_status on UNIX systems has two members called st_dev and st_ino; those are also members of the struct stat, and they are reserved identifiers which can also be provided as #define (and this is the case for st_dev on Hurd). The solution (attached) is to rename them, for example adding a "fs_" prefix (= file status) to them.

2012-02-09Change default error_code ctor to a 'named ctor' so it's more self-documenting.David Blaikie
Unify default construction of error_code uses on this idiom so that users don't feel compelled to make static globals for naming convenience. (unfortunately I couldn't make the original ctor private as some APIs don't return their result, instead using an out parameter (that makes sense to default construct) - which is a bit of a pity. I did, however, find/fix some cases of unnecessary default construction of error_code before I hit the unfixable cases) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@150197 91177308-0d34-0410-b5e6-96231b3b80d8
