The Document Foundation (TDF) is the charitable entity behind the world’s leading free/libre open source (FLOSS) office suite LibreOffice.
We are looking for an individual or company to implement an autoupdater for LibreOffice.
Currently, LibreOffice can notify the user about a new version, but download and installation require manual action by the user, it is not automated. With plans of a “rolling release” model, that results in more frequent updates, e.g. biweekly or monthly, we want to improve this system.
- The solution has to work on all currently LibreOffice-supported Windows, Linux and macOS versions.
- The implemented solution should not break the MSI-based LibreOffice installation set.
- The implemented solution cannot solely rely on app stores autoupdaters, as The Document Foundation does not provide binaries in app stores currently.
- The work has to be developed on LibreOffice master, so that it will be released in the next major version.
- The implementation has to be provided with extensive documentation, about the approach chosen to implement the above items. We expect bidders to provide documentation on both the code and the non-code parts of the implementation, e.g. methodology, structure and technical aspects.
The proposed solution might include some of the items of the following list, which is neither complete nor exhaustive, and is presented as a set of examples. These items are not mandatory to the completion of the tender, but might favor the granting of the tender in case of ex aequos, after checking that mandatory requirements are fulfilled:
- Achieve partial and/or delta downloads: in order to optimize the bandwidth of the users, the implementation might proceed with the sole download of the whole changed files (partial downloads) or chunks of changed files or the whole package (delta downloads).
- The implementation might keep track of other languages than English that the user might have installed and currently uses, and implement the download of the respective updated language packs, as well as of eventual offline help packages.
- The implementation might verify the compatibility and/or update any extensions the user might have installed and currently uses.
- The implementation is ready for the integration with the app stores’ installers/updaters.
The choice of technology or technologies used is up to the bidders. Some of the available options, with none of them being a sole strict requirement, are the following:
The idea behind this tender is described in the following required tickets, whereas the implementation we seek for does not mandate a specific technology to be used, even if the tickets suggest otherwise:
The Document Foundation will publish the related documentation under a free and open source license and make it available to the general public.
- Extensive knowledge of C++
- Experience working on the LibreOffice source code
- English (conversationally fluent in order to coordinate and plan with members of TDF)
We use free, libre and open source (FLOSS) software for development wherever possible, and the resulting work on the program code must be licensed under the Mozilla Public License v2.0.
