From 95bb5df9eda253afed15fa81340d31e03c40fe94 Mon Sep 17 00:00:00 2001 From: "Bryn M. Reeves" Date: Tue, 13 Jan 2015 17:10:06 +0000 Subject: [PATCH 37/93] [sosreport] catch OSError exceptions in SoSReport.execute() OSError exceptions during logging setup and tear down are not currently handled: Traceback (most recent call last): File "/usr/sbin/sosreport", line 25, in main(sys.argv[1:]) File "/usr/lib/python2.7/site-packages/sos/sosreport.py", line 1409, in main sos.execute() File "/usr/lib/python2.7/site-packages/sos/sosreport.py", line 1366, in execute self._setup_logging() File "/usr/lib/python2.7/site-packages/sos/sosreport.py", line 739, in _setup_logging self.sos_log_file = self.get_temp_file() File "/usr/lib/python2.7/site-packages/sos/sosreport.py", line 670, in get_temp_file return self.tempfile_util.new() File "/usr/lib/python2.7/site-packages/sos/sosreport.py", line 82, in new fd, fname = tempfile.mkstemp(dir=self.tmp_dir) File "/usr/lib64/python2.7/tempfile.py", line 304, in mkstemp return _mkstemp_inner(dir, prefix, suffix, flags) File "/usr/lib64/python2.7/tempfile.py", line 239, in _mkstemp_inner fd = _os.open(file, flags, 0600) OSError: [Errno 28] No space left on device: '/tmp/tmp.4ejNitjwcr/nospace_tmp/tmpBjPTOm' Address this by adding OSError to the list of caught exceptions in the main SoSReport.execute() method. Wrap the exception branch clean up in a try/except block to catch additional exceptions while attempting to clean up (e.g. unlink failures following an EROFS on the temporary archive path).
