Random AttributeErrors

[stefanodoni]

Hi,

I'm using naarad to analyse Linux sar and Java GC logs.

I'm getting some really weird errors, which happens randomly.

It goes like this. I execute naarad command line:

../bin/naarad -i . -o out/sar15 -c config-sar15

Result: sometimes the command completes correctly, other times I get this exception (at random places during parsing):

Traceback (most recent call last):
File "/usr/lib/python2.7/threading.py", line 810, in __bootstrap_inner
self.run()
File "/usr/lib/python2.7/threading.py", line 763, in run
self.__target(_self.__args, *_self.__kwargs)
File "/home/ste/WORKS/Programs/naarad/src/naarad/utils.py", line 812, in parse_and_plot_single_metrics
if metric.parse():
File "/home/ste/WORKS/Programs/naarad/src/naarad/metrics/sar_metric.py", line 147, in parse
datetimestamp = naarad.utils.get_standardized_timestamp(datetimestamp, timestamp_format)
File "/home/ste/WORKS/Programs/naarad/src/naarad/utils.py", line 730, in get_standardized_timestamp
dt_obj = datetime.datetime.strptime(timestamp, ts_format)
AttributeError: _strptime

Please note: this happens by executing the exact same command, with no changes to input files.

Looks like a race condition due to threading.
