strftime in python 2.2
I'm trying to make work this code in python 2.2.3:
check=datetime.datetime.today().strftime("%H%M")
but datetime is not supported in that version but just in the later.
I can't upgrade python, too many dependencies in a critical system.
How can i convert that string to have the same result?
Hope someone can help me,
Thanks in advance

Re: problem on waiting exit thread and write on file
Marc 'BlackJack' Rintsch ha scritto: > for thread in threads: > thread.join() > > Much shorter, isn't it!? :-) If i do like you tell, all thread will run together right? So i'll get troubles! I have a list of hostname, i run a network program and then i need to write some of the output that give me this command to a file. If i run the thread together, they can get problems writing on the same file. So I have splitted the list in 5 groups, the group 1 have filetmp 1, group 2 have filetmp 2 and so on... Then I start one thread for all groups, so 5 threads running together, the other waiting the end of one of them. -- http://mail.python.org/mailman/listinfo/python-list
problem on waiting exit thread and write on file
I have a list of parameters.
I need to run in thread a command, one thread for one parameter.
So i made a for loop, creating 5 threads and waiting their stop with:
for parameter in parameters
Thread{
write on BW2
}
Main {
open file BW2 for write
. (creating list of thread with a counter)
Stopped=False
while (Stopped == False):
if not thread5.isAlive():
if not thread4.isAlive():
if not thread3.isAlive():
if not thread2.isAlive():
if not thread1.isAlive():
Stopped=True
if (Stopped == False):
time.sleep(0.3)
..
close file BW2
}
Somethimes i get however the error that i can't write on a file
already closed
There is a way more easy to wait that all children exit and to run a
queue of threads?
I tried also this:
a=0
while (a == 0):
try:
os.waitpid(-2, 0)
except OSError, exc:
# all CHILD finished
a=1
but the same problem persist. The only way to don't have error is to
had a time.sleep(4) before closing the file from the main program.

I reply by myself:

cmd = Popen3('command','r')
waiting=0
while (cmd.poll()==-1):
time.sleep(0.1)
waiting+=1
if (waiting>3): os.kill(RESULT.pid,0)

popen e pclose on python 2.3 question
I need to run a network program and return output in a variable name
without use temporany file.
So i tought to use popen (i'm using python 2.3, i can't upgrade).
RESULT = os.popen('command'+HOST, 'r')
I have a problem about it:
i need to kill the child if the program take more than 300 ms, but i
need also to wait this 300 ms to have the reply.
os.pclose(RESULT) give me:
AttributeError: 'module' object has no attribute 'pclose'
cause pclose doens't exist in 2.3.and a time.wait(0.3) is not a so
clean code.
Someone can give me some tricks? I would like a script portable on
python 2.3, i would not like
to compile on 2.5.

checking if hour is between two hours
Hi all, i'm again working on my script of parsing logfiles :)
I putted a new function to disable the rule of error between a certain
hours, cause i want to use it as a monitoring script that run every 5
minutes and to disable error in hours of maintenance.
But i have some "problems" to check it.
In the rule-file i have HHMM(start) and HHMM(stop) - 0 0 to
disable hours check (i can't check the timestamp in logfile cause not
all the logfiles that i need to check have a timestamp in it).
In the script i wrote:
Actualtime=datetime.datetime.today().strftime("%H%M")
if (start>end):
if (Actualtime>start):
end=int(Hcheck)+1
else:
if (int(Actualtime)int(end)) or
((start=="0") and (end=="0")) ):
rule=error
...blablabla
else:
rule=skip
blablabla
Why i don't use the complete date with YYMMDDHHMM?
Think about a rule that need to be disabled from hours 20:00 to
04:00.
If i use also yymmdd, in the rule file i need to write a 2000 and
0400+1, the +1 to tell the script that the end
is in the day after, to add a day. But it will work just till the
, hour in witch the day will change.
The script work, but is not so "clean"i just would like some
advice to make it more clean, if possible.
Like always, thanks in advance for the helps :)

I was asking that cause in the code i wrote this: for y in range(0, len(skip_lst) ): if (re.search(skip_lst[y], line)): skip=1 break In skip_lst there are the regexp and strings (on one line) to match with "line".

regexp match string with word1 and not word2
Hello, i have again problem with regexp :-P I need to match all lines that contain one word but not contain another. Like to do "grep one | grep -v two:" The syntax of the string is: (any printable char)two:(any printable char)one(any printable char) Example: Apr 30 00:00:09 v890neg0 two: [ID 702911 daemon.one] findings: blablabla I tried with: .*[^t][^w][^o].*one.* but is not working, the string is always match and in other tries using "less logic" i get always some different match :-( P.S: i can't have more re.search, so i just need ONE regexp -- http://mail.python.org/mailman/listinfo/python-list

Hi, i need to "compile" a python source (2.3.6) to make it standalone on Solaris 9. I get this warning on freezing my source: "Warning: unknown modules remain: _locale _random _socket array binascii cStringIO datetime fcntl math pwd select strop termios time" in the source i have: "import os, stat, re, datetime, time, glob" and running the frozen application I get: "ImportError: No module named datetime" like i have read in the old post in this newgroup i tried to recompile python to avoid shared libraries (i used ./configure --disable- shared), and to reinstall python of course (recompiling my source) but the same problem occour. In Modules/Setup i don't have shared libraries and the line "*shared*" is commented. I have tried also other freeze application (Gordon MacMillan, cx_freeze), but i get a fatal error importing zlib also if i have installed right. Someone have some tips?

exception just to avoid output error (newbie)
Hi
I'm trying to delete some files, but i get an exception error if the
file don't exist.
I can use an {if fileexist(file) then delete}, but it will get cpu
time.
So i catch the exception with:
try: os.remove(filename)
except EnvironmentError: error=1
If i just want to avoid the output error, is this the right way to
write the code?
I don't care of get if is in error, but an "except EvironmetError"
without the ":" will give me a sytax error.
Am I too much complicated? :-)

split and regexp on textfile
Hi,
i have a problem with the split function and regexp.
I have a file that i want to split using the date as token.
Here a sample:
-
Mon Apr 9 22:30:18 2007
text
text
Mon Apr 9 22:31:10 2007
text
text
I'm trying to put all the lines in a one string and then to separate
it
(could be better to not delete the \n if possible...)
while 1:
line = ftoparse.readline()
if not line: break
if line[-1]=='\n': line=line[:-1]
file_str += line
matchobj=re.compile('[A-Z][a-z][a-z][ ][A-Z][a-z][a-z][ ][0-9| ][0-9]
[ ][0-9][0-9][:]')
matchobj=matchobj.split(file_str)
print matchobj
i have tried also
matchobj=re.split(r"^[A-Z][a-z][a-z][ ][A-Z][a-z][a-z][ ][0-9| ]
[0-9][ ][0-9][0-9][:]",file_str)
and reading all with one:
file_str=ftoparse.readlines()
but the split doesn't work...where i am wronging?

parsing text in blocks and line too
Goodmorning people :) I have just started to learn this language and i have a logical problem. I need to write a program to parse various file of text. Here two sample: --- trial text bla bla bla bla error bla bla bla bla bla bla bla bla on more lines trial text bla bla bla bla warning bla bla bla more bla to be grouped with warning bla bla bla on more lines could be one two or ten lines also withouth the tab beginning again text text can contain also blank lines text no delimiters -- Apr 8 04:02:08 machine text on one line Apr 8 04:02:09 machine this is an error Apr 8 04:02:10 machine this is a warning -- parsing the file, I'll need to decide if the line/group is an error, warning or to skip. Mine problem if how logical do it: if i read line by line, I'll catch the error/warning on first and the second/third/more will be skipped by control. Reading a group of line i could lose the order on the output: my idea is to have an output in html with the line in the color of the check (yellow for warning, red for error). And i have also many rules to be followed so if i read one rule and then i search on the entire file, the check will be really slow. Hope someone could give me some tips.
