VMware vCloud Suite SDK for Perl 6.0 Release Notes

Released 12 MAR 2015

 

This document contains the following sections:

Overview

This SDK provides programmatic access to new features introduced in vSphere 6.0 and existing features that did not have a public API prior to the vSphere 6.0 release. Access to existing features is exposed through the vSphere Web Services API. The vCloud Suite SDK for Perl also contains samples that demonstrate how the libraries work with other vSphere APIs.

The version 6.0 SDK enables programmatic access to the following services:

  • Service discovery using Lookup Service
  • Authentication (Single Sign-On)
  • Session management
  • Tagging
  • Content Library

Note:  Single Sign-On authentication is available through the VMware vCenter Single Sign On API. Service discovery is available through the Lookup Service API.

Distribution Kit

When you extract the contents of the vCloud Suite SDK for Perl distribution kit, the vCloud Suite client SDK is placed in the VMware-vCloud-Suite-SDK-Perl-6.0.0 directory:

    VMware-vCloud-Suite-SDK-Perl-6.0.0/
        client/
        docs/
        EULA
        README

You can download the vCloud Suite SDK for Perl distribution kit from the VMware Developer Center.

Known Issues

The following issues were discovered during testing.

  • Internal Server Error if Tagging Description Field is Empty

    The Tag Category Description field is optional in the vSphere Web Services API, but it is mandatory in the vCloud Suite SDK. Therefore, if the description field is empty, the vCloud Suite SDK can return an internal server error that states, "the ‘description’ field of the Category model is empty".

    Workaround:

    When creating tags, do not leave the description field empty. If you do not have any description, you may add a whitespace character (i.e. space).

  • Unauthenticated exception following long-running operation

    After an API client completes a long-running operation, such as an upload to the content library, the next operation might fail with an "Unauthenticated exception" message. This happens if the long running operation did not complete within the lifetime of the authentication session.

    Workarounds:

  • Keep the session alive by issuing short operations on another thread until the long running operation completes.
  • Increase the session length using the VMware vSphere Web Client. Select Administration > System Configuration > Services > vAPI Endpoint > Manage > General, and increase the value for the Maximum session idle time.

  • Perl async call limitations

    Some of the key CPAN modules are not thread-safe. They may crash the Perl interpreter during execution, or may dump core memory on termination.

    To work around these difficulties, the vCloud Suite SDK for Perl creates long lived threads to handle async calls. On most systems, frequent and continual creation and destruction of async calls can lead to an ever-increasing number of threads that increases the memory footprint of the Perl interpreter. It is a best practice to not use Perl async calls frequently.

  • Limitation with certificate validation

    The samples in the vCloud Suite SDK for Perl do not perform certificate validation for SSO endpoints. The samples do validate certificates from other service endpoints.
