New submission from Harry Lam (WaXHeLL): Storage Spaces (RAID volumes) under Windows 8.1 / Server 2012 R2 use ReFS which does not support hard links.
If the Users directory has been moved to a ReFS volume, it causes any script that uses os.link to hang (pip is one of the notable examples). As a side effect -- this also makes it so that Python can not be uninstalled if pip is installed. The script must be terminated with a ctrl-c. Tested under 3.5.0b3 as well as 3.4.3 (x64 as well as x32). Traceback from ctrl-c on 'pip list': I:\>pip list Traceback (most recent call last): File "C:\Program Files\Python 3.5\lib\site-packages\pip\_vendor\lockfile\linkl ockfile.py", line 30, in acquire os.link(self.unique_name, self.lock_file) OSError: [WinError 50] The request is not supported: 'I:\\Users\\[[USER NAME REMOVED]]\\AppData\ \Local\\pip\\Cache\\[[COMPUTER NAME REMOVED]]-1d14.781968199621979134564595' -> 'I:\\Users\ \[[USER NAME REMOVED]]\\AppData\\Local\\pip\\Cache\\selfcheck.json.lock' During handling of the above exception, another exception occurred: Traceback (most recent call last): File "C:\Program Files\Python 3.5\lib\runpy.py", line 170, in _run_module_as_m ain "__main__", mod_spec) File "C:\Program Files\Python 3.5\lib\runpy.py", line 85, in _run_code exec(code, run_globals) File "C:\Program Files\Python 3.5\Scripts\pip.exe\__main__.py", line 9, in <mo dule> File "C:\Program Files\Python 3.5\lib\site-packages\pip\__init__.py", line 217 , in main return command.main(cmd_args) File "C:\Program Files\Python 3.5\lib\site-packages\pip\basecommand.py", line 220, in main pip_version_check(session) File "C:\Program Files\Python 3.5\lib\site-packages\pip\utils\outdated.py", li ne 134, in pip_version_check state.save(pypi_version, current_time) File "C:\Program Files\Python 3.5\lib\site-packages\pip\utils\outdated.py", li ne 71, in save with lockfile.LockFile(self.statefile_path): File "C:\Program Files\Python 3.5\lib\site-packages\pip\_vendor\lockfile\__ini t__.py", line 238, in __enter__ self.acquire() File "C:\Program Files\Python 3.5\lib\site-packages\pip\_vendor\lockfile\linkl ockfile.py", line 49, in acquire time.sleep(timeout is not None and timeout/10 or 0.1) KeyboardInterrupt ---------- components: Windows messages: 247496 nosy: Harry Lam (WaXHeLL), paul.moore, steve.dower, tim.golden, zach.ware priority: normal severity: normal status: open title: os.link issues on Windows & ReFS type: crash versions: Python 3.4, Python 3.5 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue24738> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
