MailNews:Memory Bloat and Leak Tests

<< Back to MailNews:Performance Testing

Please do not edit this page unless you are on the Thunderbird or SeaMonkey MailNews team. Your feedback and comments are welcomed on the discussion page.

Note: MailNews here refers to either Thunderbird, or the Mail/Newsgroups/Address Book part of SeaMonkey

Aim

• To provide a continuous check within Mailnews and its sub-components for the following items:
  1. Total memory leaks.
  2. Total memory usage (aka bloat).
• Provide a consistent number from build to build where no source code has changed.

Note, it would be difficult to test every possible configuration/dialog, but the components that represent the main day-to-day usage within MailNews should be checked where possible.

Method

• The method of testing memory bloat and leaks will be the same, using the same run of test data.
• With a pre-defined profile run up:
  1. MailNews
  2. Address Book
  3. Message Compose
• Measure Leaks and Bloats, in a similar way to Firefox.

TBD: do we want to select different messages/folders, if so how?

Pre-defined profile

Requirements:

• One POP3 account (Mails TBD)
• One Identity
• One SMTP server defined (not used)
• One Address Book where PAB has 1000 entries

TBD: Newsgroup/rss servers? TBD: Global Inbox? - No?

No servers will be checked for new mail on start-up.
