Notices of using Subversion

If you want to use Subversion, for example, updating ports tree, you should pay attention to the following issues:

(1) If your server works behind a proxy, you should modify your Subversion configuration file:

# cat ~/.subversion/servers
[global]
http-proxy-host = web-proxy.xxxx.com
http-proxy-port = 8080
http-compression = no

Otherwise, you may encounter following errors:

# svn checkout https://svn.FreeBSD.org/ports/head /usr/ports
Error validating server certificate for 'https://svn.freebsd.org:443':
 - The certificate is not issued by a trusted authority. Use the
   fingerprint to validate the certificate manually!
 - The certificate hostname does not match.

Or:

# svn checkout https://svn.FreeBSD.org/ports/head /usr/ports

(2) If you meet similar errors like as follows executing svn command:

You should update your SQLite:

# pkg upgrade sqlite3
