Python users,
I am parsing an AIX trace file and creating a dictionary containing
keys (PIDS) and values (a list of TIDS). With PIDS being unique process ids
and TIDS, being a list of thread ids. My function populates the keys so
that they are unique, but my list contains duplicates.
Can someone point me in the right direction so that my dictionary value
does not contain duplicate elements?
here is what I got.
--------------<portion of code that is relevant>------------------
pidtids = {}
# --- function to add pid and tid to a dictionary
def addpidtids(pid,tid):
pidtids.setdefault(pid,[]).append(tid)
# --- function to parse a file
def grep(pattern, fileObj, include_line_nums=False):
r=[]
compgrep = re.compile(pattern)
for line_num, line in enumerate(fileObj):
if compgrep.search(line):
info = line.split()
p = info[7].lstrip("pid=")
t = info[8].lstrip("tid=")
addpidtids(p,t)
# process trace.int
tf = open(tracefile, 'r')
grep("cmd=java pid",tf)
tf.close()
--------------</portion of code that is relevant>------------------
Any help would be greatly appreciated.
Thanks,
Chad
