答复: Inquiry Regarding Sending Patches to DPDK

[王颢]

Dear Stephen,

Now I have a better understanding of the anonymous sending suggested by the company's IT department. Since the second-factor authentication for the email account is Microsoft's Okta, which seems not straightforward to configure with an account and password, they have enabled anonymous sending for me. Here's how it works approximately: When I send emails, I don't need to input an account or password. Instead, I just need to configure the server and port number, and I can send emails. Attached below is the script I've written. However, it seems there are some issues, and perhaps I need to conduct further research.

test result: https://mails.dpdk.org/archives/dev/2024-August/299466.html
python:
#!/usr/bin/env python3
import smtplib  
from email.mime.multipart import MIMEMultipart  
from email.mime.text import MIMEText  
from email.mime.base import MIMEBase  
from email import encoders  
  
smtp_server = 'smtpsrv.realsil.com.cn'  
smtp_port = 25
  
from_addr = 'howard_wang at realsil.com.cn'  
to_addr = 'dev at dpdk.org'

msg = MIMEMultipart()
msg['From'] = from_addr
msg['To'] = to_addr
#msg['Subject'] = 'test anonymous send mail'

filename = '0001-net-r8169-add-PMD-driver-skeleton.patch'  
with open(filename, 'rb') as attachment:  
    part = MIMEBase('application', 'octet-stream')  
    part.set_payload(attachment.read())  
    encoders.encode_base64(part)  
    part.add_header('Content-Disposition', f"attachment; filename= {filename}")  
    msg.attach(part)  

try:  
    server = smtplib.SMTP(smtp_server, smtp_port)   
    server.sendmail(from_addr, [to_addr], msg.as_string())  
    server.quit()  
    print('Mail sent successfully!')  
except Exception as e:  
    print(f'Failed to send mail: {e}')

Thanks!
Howard Wang

The IT department has suggested that I abandon using the "git send-email" method, as configured through git config, to send patches to DPDK. Instead, they have recommended using "Exchange anonymous send mail." However, I believe this approach might not be feasible.

There are two issues here:
Using git send-email is not required. You can generate patch files and put them in your email.
BUT Microsoft Exchange does not preserve text formatting in messages. Any patches sent that way are usually corrupted.

At Microsoft, we ended up using a special server (not Exchange) to send Linux and DPDK patches. Or using non-corporate accounts.
