Description

« Hide

Prerequisites:
QB is running under logged into OS user
QB config uses Subversion repository. Subversion user specified in config is differrent then OSuser uses to access SVN repo (e.g. "svnbrowser" & "svncommitter" accordingly, and, for the worse,"svnbrowser" has read-only access)

Steps
After building a config, SVN "svnbrowser" auth requisites are cached, so "svn commit" fails and OSuser has to specify svn --username to replace auth cache

That is annoying behaviour

Subversion plugin has to use "--no-auth-cache" option to run checkout (as Luntbuild does)

Adding "-no-auth-cache" will make it impossible to cache server certificate if connection is done through ssh or https, and may result in hanging builds. In normal cases, caching credentials will not be a problem as QuickBuild server and build agents should be running from a different machine other than developer's local machine.

But accordingly to QB WIKI (http://wiki.pmease.com/display/qb30/Working+with+Subversion)

>>Handling https and svn+ssh schema

>>To connect to Subversion repository with https and svn+ssh schema, you'll need to permanently accept the Subversion server's certificate from the command line before running QuickBuild. The detailed step is:
>>Login to the build machine as the user that will be used to launch QuickBuild process.
>>Connect to your Subversion repository using Subversion command line, and if the server asks for whether or not to save credentials for subsequent usage, choose "yes".
>>Make sure that subsequent Subversion command does not prompt for username and password.
>>Start QuickBuild process.

So, why --no-auth-cache does matter here?

The wiki is no accurate. QB is able to accept permanent server certificate programmatically at start of a build, and this requires that option "--no-auth-cache" is not present, otherwise, Subversion will only accept certificate temporarily.
