Boost C++ Libraries: Ticket #10145: Win2k8R2 specific: boost::filesystem::is_directory() returns false for a directory under C:\Windows\System32

Wed, 25 Jun 2014 12:08:53 GMT

Wrapping the above reproduction procedure into a code block (sorry, should've done originally):

C:\>mkdir temp_dir
C:\>cd temp_dir
C:\>for /L %i in (1, 1, 2000) do mkdir test_dir_%i
C:\>mkdir test_dir
Now try to execute the following statements under a debugger: 'is_directory()' always returns false.
boost::filesystem::path directory("C:\\temp_dir\\test_dir");
bool isDir = boost::filesystem::is_directory(directory);

Want to close this as "not an issue" -- I wasn't able to reproduce this on other systems.

summary changed

summary boost::filesystem::is_directory() returns false for a directory in Windows → Win2k8R2 specific: boost::filesystem::is_directory() returns false for a directory under C:\Windows\System32

Changed the summary correspondingly; here're the exact reproduction steps:

C:\>mkdir C:\Windows\System32\test_dir
Now try to execute the following statements under a debugger: 'is_directory()' always returns false for some weird reason.
boost::filesystem::path dirPath("C:\\Windows\\System32\\test_dir");
bool isDir = boost::filesystem::is_directory(dirPath);

Note that things work as expected when the directory is created under 'C:\Windows\System', which features permissions identical to 'C:\Windows\System32':

C:\>mkdir C:\Windows\System\test_dir
'is_directory()' normally returns true when passing over the following statements:
boost::filesystem::path dirPath("C:\\Windows\\System\\test_dir");
bool isDir = boost::filesystem::is_directory(dirPath);

Might this be due to the Windows File System Redirector that will redirect access to those paths for 32-bit binaries? I'd include a link, but it thinks it is spam, so just search for "msdn File System Redirector" and you'll find it.

Oh, man, sure that's it! I get caught on WOW64 thingies every now and then; sorry for bothering. The ticket can freely be closed/rejected.
