--- Comment #2 from Michael Meeks ---
First - Joel ! wonderful to see you again - hope all's well; would love to
catch up.
Second - distributed locking is a living hell. Even if making this rather
complex use-case possible was something we could do easily (and that's far from
clear - it's a mixed Nextcloud, Online issue) - we would then get a slew of
other bugs and use-cases around leaked lock-files; whether Nextcloud should try
to create lock files when it believes a document is open in Online (but only
when that is un-modified? rather than waiting for an hour to be expired?) etc.
- the area opens a enterprise-sized can of worms =)
Some of the reasons why I've resisted getting involved in distributed locking
at least ;-) and that's before we get into leaked locks, inconsistent locks
(where there is an OS/SMB lock on the file, but no lock-file or vv.) and so on
... anyhow.
It is possible we can improve this with some concerted effort; in theory WOPI
has locking extensions that can be implemented, but ... its a massive job to
get right, horribly hard to validate, and will inevitably be deeply
disappointing.
I'd prefer FWIW to work on more robust ways of visualizing and/or merging
changes ;-) now that is something generally useful & interesting.
Nevertheless - we should prolly keep this open, in the long run we may have to
do something here.
Philippe - how are you feeling about this ? and/or do you feel motiviated to
come up with a big matrix / description of the cases we need to handle
(including all the asynchronous races between each of those - it will be many
tens of different stats) - and what we need to do in those cases.
