I had a minor fight with south earlier today, where someone had created a migration with south 0.7, and I needed it to work with south 0.6.
Needless to say that it would be a pain to manually convert it from the better 0.7 format back into 0.6, so I wrote a fairly small python script, that does the job.
I had to get some statistics about file sizes today, but couldn’t really find a tool for the job, so naturally, I wrote one.
Seeing as there is no really easy way to do a HTTP HEAD request from python, I wrote up the following small method:
In advance I’d like to apologize for the method that assemblies the request path.
Update: Added handling of redirects.
def http_head(url): import httplib import urlparse redirects = 0 while redirects < 10: scheme, netloc, path, query, fragment = urlparse.urlsplit(url) if scheme == 'https': conn = httplib.HTTPSConnection(netloc) else: conn = httplib.HTTPConnection(netloc) conn.request("HEAD", "%s%s%s%s%s" % (path, query and "?" or "", query, fragment and "#" or "", fragment)) res = conn.getresponse() if res.status in (301, 302) and res.getheader('location'): url = res.getheader('location') redirects += 1 else: break return res.status, res.reason
I needed to send an email, so I came up with this:
def send_plain_mail(subject, body, from_mail, to): import smtplib from email.MIMEText import MIMEText from email.Encoders import encode_quopri msg = MIMEText(body, 'plain', 'iso-8859-1') msg['Subject'] = subject msg['From'] = from_mail msg['To'] = to s = smtplib.SMTP() s.connect() s.sendmail(from_mail, [to], msg.as_string()) s.close()
Not rocket science, but it gets the job done.
At work we yestoday decided to update our internal url structure for our client test sites, issue management systems and such arround a bit. Seeing as we decided on purchasing a genuine signed ssl wildcard certificate, we needed to change our url’s a bit.
The code for a very simple asynchronous socket server written in python utilizing the asynchat module. It’s all in good fun.
