Lost content on failed writes

[loleg]

Realms should return to the Edit screen in case there is any problem saving the content, notifying the user (as with the logged out message) to avoid data loss.

In my installation a user began reporting lost content. No errors, no popups, just edits that were gone as soon as she clicked Publish. In trying to reproduce the problem, I noticed erroneous permissions in the filesystem. Instead of deploy:deploy the owner became root:root on some of the files.

This is likely because I am synchronising the Git repository using an external git process as well as Realms. To me the ability to do this is one of the top features of the wiki. I am now ensuring that permissions are being correctly set, however the wiki interface must do everything possible to avoid data loss: in this case, at least alerting the user if the save did not succeed.

I'm experiencing this lost content problem occasionally.
I haven't pinned down what usage pattern provokes it.
I'm running a docker container built from the current head on docker for windows with a host folder mounted to /home/wiki/data.

So far I've been able to rescue my content by bringing up chrome developer tools and copying it out of the local storage field.
