Rafael Espindola a0d9b6b693 Split openFileForRead into Windows and Unix versions. 
This has some advantages:

* Lets us use native, utf16 windows functions.
* Easy to produce good errors on windows about trying to use a
directory when we want a file.
* Simplifies the unix version a bit.

Rafael Espindola b6fea4c618 Don't fallback to copy + delete in rename. 
Rename's documentation says "Files are renamed as if by POSIX rename()". and it
is used for atomically updating output files from a temporary. Having rename
fallback to a non atomic copy has the potential to hide bugs, like using
a temporary file in /tmp instead of a unique name next to the final destination.

Rafael Espindola 77021c9487 Add a version of sys::fs::status that uses fstat.

Rafael Espindola 9da91a0e03 Instead friending status, provide windows and posix constructors to file_status. 
This opens the way of having static helpers in the .inc files that can
construct a file_status.

Rafael Espindola 4d08d8bada Use status to implement file_size. 
The status function is already using a syscall that returns the file size.
Remember it and implement file_size as a simple wrapper.

No functionally change, but clients that already use status now can avoid
calling file_size.

Rafael Espindola e79a87226a Improvements to unique_file and createUniqueDirectory. 
* Don't try to create parent directories in unique_file. It had two problem:
   * It violates the contract that it is atomic. If the directory creation
     success and the file creation fails, we would return an error but the
     file system was modified.
   * When creating a temporary file clang would have to first check if the
     parent directory existed or not to avoid creating one when it was not
     supposed to.

* More efficient implementations of createUniqueDirectory and the unique_file
  that produces only the file name. Now all 3 just call into a static
  function passing what they want (name, file or directory).

Clang also has to be updated, so tests might fail if a bot picks up this commit
and not the corresponding clang one.

Rafael Espindola 158d537c5a Add GetCurrentDirectory back. 
It looks like clang-tools-extra/unittests/cpp11-migrate/TransformTest.cpp
depends on the behaviour of the old one on Windows. Maybe a difference
between GetCurrentDirectoryA and GetCurrentDirectoryW?

Sylvestre Ledru 12c44e57f5 The assumption that /proc/self/exe always exists is incorrect. 
For example, under a Linux chroot, /proc/ might not be mounted.
Therefor, we test if this file exist. If it is the case, use it (the current
behavior). Otherwise, we fall back to the detection used by *BSD.

The issue has been reported initially on the Debian bug tracker:

Nick Lewycky 9ee5f77141 Don't look at $PWD in GetCurrentDirectory. 
llvm-svn: 136477
 2011-07-29 18:26:59 +00:00
Nick Lewycky 38b9b568b9 Teach Path::GetCurrentDirectory to use $PWD, to support users who like to do 
screwy things by setting PWD != getcwd(). For example, some developers I know
will use this to control the value in gcc's DW_AT_comp_dir value in debug
output. With this patch, that trick will now work on clang too.

The only other effect of this change is that the static analysis will now
respect $PWD when reporting the directory of the files in its HTML output. I
think that's fine.

Chad Rosier 30c3463309 By default mkstemp() creates a temporary file with mode 0600, but the mode 
used for open is 0666.  Therefore, add the necessary permission bits for
consistency.
