|
Hi,
This is an util to get the time elapsed from each merged package from emerge.log. Also this is my first python script. It "seems" to work for me.
A copy of emerge.log should be in the same dir. To execute:
> ploc emerge.log
| Code: |
#!/usr/bin/python
#
# name: ploc -- process log
# description: analyze a copy of emerge.log to get the duration to
# emerge a package
#
import string
import sys
fn = sys.argv [1]
op =''
if (len(sys.argv[1:]) > 0):
op = sys.argv [1]
file=open (fn, 'r')
else:
print "need a log file name\n"
sys.exit(0)
def parse_line (il):
# only get lines start with
# ***, >>>, :::
# ignore the rest
l= string.split (il)
time = l[0][:-1]
token = l[1]
result = ''
if (token == '***' and len(l) > 3):
# some case nothing after emerge
# so len 3 filter it out
tok = l[3] #name of package
# ignore all these cases
keys= ['search','rsync','clean',
'clean', '--searchdesc',
'umerge','sync']
if (l[2] == 'emerge' and (tok not in keys)):
if (tok in ['--update', '--emptytree']):
name = l[4]
else:
name = l[3]
return [time,'*', name, 'started']
elif (l[2] == 'exiting'):
return [time,'*', 'ended']
else:
return ['ignore']
elif (l[1] == '>>>'):
if (l[2] == 'emerge'):
return [time,'>' , l[6], 'started']
else:
return ['ignore']
elif (l[1] == ':::'):
return [time, ':', 'ended']

return ['ignore']
def t_xtract (l):
# get the time from a list
