| | 2 | = Advanced Notification enhancements |
| | 3 | |
| | 4 | == Context |
| | 5 | |
| | 6 | The TracNotification system has not kept up with the requirements users, administrators and developers have. The th:AnnouncerPlugin was developed to provide a more flexible notification system. |
| | 7 | |
| | 8 | An alternative [wiki:Announcer proposal] to replace the !TracNotification system with the !AnnouncerPlugin has existed for some years. |
| | 9 | |
| | 10 | == Proposal |
| | 11 | |
| | 12 | Improve the !TracNotification system by: |
| | 13 | * Deprecating the inflexible `Notify` class hierarchy. |
| | 14 | * Adding new infrastructure (based on !AnnouncerPlugin's proven design where appropriate) on a topic-by-topic basis. |
| | 15 | * Adopting some general advanced features. |
| | 16 | * Enabling plugins to provide more experimental or very specific features. |
| | 17 | |
| | 18 | === Coexistence with Announcer |
| | 19 | |
| | 20 | This proposal would not integrate or replace Announcer as a whole. Future versions of Announcer would ideally be compatible with new !TracNotification system and rebase additional non-core features on the new core infrastructure. |
| | 21 | |
| | 22 | Future versions of announcer could also provide upgrade paths from older versions of the plugin to the new core infrastructure. |
| | 23 | |
| | 24 | DB tables, configuration sections and extensions points adopted in core from Announcer may best be renamed to avoid confusion and upgrade troubles (especially when slightly modified). |
