| | 24 | == Overview == |
| | 25 | |
| | 26 | This RFC intends to deprecate DWF support in MapGuide for eventual removal in a future release after 3.3 |
| | 27 | |
| | 28 | == Motivation == |
| | 29 | |
| | 30 | A [https://themapguyde.blogspot.com/2018/10/a-short-mapguide-poll-what-you-said.html recent survey] showed that a majority of users take advantage of DWF-related support and services in MapGuide. |
| | 31 | |
| | 32 | Coupled with Autodesk backing out of MapGuide development and the technological dead-end of the DWF toolkit and the limited knowledge among remaining developers in maintaining/fixing/enhancing this aspect of MapGuide, there is not much justification to keep this support around. |
| | 33 | |
| | 34 | == Proposed Solution == |
| | 35 | |
| | 36 | Mark the following classes as deprecated: |
| | 37 | |
| | 38 | {{{ |
| | 39 | TBD |
| | 40 | }}} |
| | 41 | |
| | 42 | Usage of Drawing Source and Drawing Layer Definition resources is also deprecated. |
| | 43 | |
| | 44 | The resource service currently re-uses DWF Toolkit zip package code for package loading and creation. In order to prepare for eventual removal of DWF support (and the DWF Toolkit) in a future release, the package loading and creating code will be replaced with an alternate zip implementation from the minizip contrib library that is already part of our internal zlib sources. |
| | 45 | |
| | 46 | == Implications == |
| | 47 | |
| | 48 | The deprecation of DWF support should be a signal to users to look at alternative solutions to existing functionality that DWF provided. |
| | 49 | |
| | 50 | == Test Plan == |
| | 51 | |
| | 52 | Ensure package creation and loading are still functional under the replacement minizip implementation. |
| | 53 | |
| | 54 | == Funding / Resources == |
