SSL and subversion client

Submitted by sandip on Mon, 02/07/2011 - 12:03

Unlike web browsers, the CA root cert is not installed by default for svn clients. You would need to tell the client where to find it in order to trust the ssl cert.

Reference: svnbook

For GoDaddy signed certs, download their root certs available at:

http://certificates.godaddy.com/repository

You would need both the pem encoded gd-class2-root.crt and gd_intermediate.crt .

Then in subversion client global settings, tell it the path to the certs:

ssl-authority-files = /path/to/gd-class2-root.crt;/path/to/gd_intermediate.crt

This should then trust the ssl cert.

svn checkout via shell script

Submitted by sandip on Mon, 03/30/2009 - 23:19

Very often development servers only have self-signed certificate for ssl connection. I've recently had to create a script that would checkout from a https svn repository that would fail with "Server certificate verification failed: issuer is not trusted..." . Below is a workaround used to temporarily trust the certificate.

svn --username $SVN_USER --password $SVN_PASS --no-auth-cache checkout ${REPO_URL}/${REPO_PATH} $REPO_PATH <<EOF 2>/dev/null
t
EOF
