bufsize must be an integer error while grepping a message

Question

I am running into following error while trying to grep for a message consisting of multipe lines in a log...can anyone provide inputs on how to overcome this error?

Answer 1

The subprocess.Popen class expects an argument list like this:

Popen(args, bufsize=0, ...)

So you're passing it:

• args = git
• bufsize = log

Hence the error (bufsize expects an integer value). The command vector needs to be a list, like this:

gerritlog = Popen(['git','log','--grep','gerrit_commitmsg'], stdout=PIPE, stderr=PIPE)
