Maintenance/read-only mode

[burner1024]

Is your feature request related to a problem? If so, please describe.

I'd like to upgrade Weblate, however I'm concerned that users will access it during the upgrade and that'll interfere with upgrade process and/or result in a loss of work in case I need to roll back.

Describe the solution you'd like

Single-button lock down of all "write" actions for all users except admins. Display a custom note with some info.

Describe alternatives you've considered

I could lock it down by ip on webserver level, but that will not be as transparent, break badges on external sites in the meantime, etc.

Additional context

In fact, I'd be interested to know how you do it on https://hosted.weblate.org. Is it documented anywhere?

On Hosted Weblate we know what changes are being deployed (it is updated more frequently) and depending on that one of workflows is used:

• In case of non-breaking changes, the app is kept running, upgraded and uwsgi restarted.
• In case of bigger updates, the app is stopped, upgraded and then started.

For the second case we have web server configured in a way to display a maintenance message (which is here: https://github.com/WeblateOrg/wllegal/blob/main/wllegal/templates/weblate_50x.html).

The maintenance mode of Weblate would not address this in general - the database schema changes between versions and the old version is not be able to work with the new one.

This issue looks more like a support question than an issue. We strive to answer these reasonably fast, but purchasing the support subscription is not only more responsible and faster for your business but also makes Weblate stronger.
