New submission from Ian Donaldson <i...@ekit-inc.com>: test_posix hung on Solaris 9 ... traced to getcwd test hanging.
This in turn was traced to the very long filename case... It seems posixmodule was modified (since py2.4.3 at least) to retry getcwd with a bigger buffer if ERANGE occurs. However on Solaris 9 its not documented that ERANGE also occurs if getcwd(3) can't cope with the path length, even if the buffer is big enough. This causes posix_getcwd() to loop malloc'ing a bigger buffer, forever. I enclose a patch that limits the damage, to 1Mbyte at least. (not sure if more recent Solaris 9 patches than we have provide another solution) On Solaris 10, there is no problem as the getcwd() is implemented as a system call. ---------- components: Build files: EKIT.PATCH5 messages: 93028 nosy: iandekit severity: normal status: open title: getcwd hangs and leaks mem on Solaris <= 9 in very long file name case type: resource usage versions: Python 2.6 Added file: http://bugs.python.org/file14955/EKIT.PATCH5 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue6976> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
