Add comprehensive OAuth 2.0 authentication support for SMTP to address
Microsoft's Basic Authentication retirement in September 2025.
Key features:
- OAuth 2.0 SASL XOAUTH2 authentication mechanism
- Microsoft Azure AD integration with client credentials flow
- Backward compatible with existing basic authentication
- Comprehensive configuration options in .env.example files
- Enhanced SMTP client with dependency injection for better testability
- Complete test coverage with proper mocking
Configuration:
- SMTP_AUTH_TYPE: Choose between 'basic' and 'oauth2' authentication
- Microsoft OAuth 2.0 settings for Azure AD integration
- Automatic token acquisition using client credentials flow
Files changed:
- Enhanced SMTP client with OAuth 2.0 support
- New mail module structure under libs/mail/
- Updated configuration system with OAuth settings
- Comprehensive documentation and setup instructions
- Complete test suite for OAuth functionality
This change ensures compatibility with Microsoft Exchange Online
after Basic Authentication retirement.
This PR introduces UUIDv7 implementations in both Python and SQL to establish the foundation for migrating from UUIDv4 to UUIDv7 as proposed in #19754.
ID generation algorithm of existing models are not changed, and new models should use UUIDv7 for ID generation.
Close#19754.
This pull request introduces a feature aimed at improving the debugging experience during workflow editing. With the addition of variable persistence, the system will automatically retain the output variables from previously executed nodes. These persisted variables can then be reused when debugging subsequent nodes, eliminating the need for repetitive manual input.
By streamlining this aspect of the workflow, the feature minimizes user errors and significantly reduces debugging effort, offering a smoother and more efficient experience.
Key highlights of this change:
- Automatic persistence of output variables for executed nodes.
- Reuse of persisted variables to simplify input steps for nodes requiring them (e.g., `code`, `template`, `variable_assigner`).
- Enhanced debugging experience with reduced friction.
Closes#19735.
