File synchronization plugin idea

[Viktor Porvaznik]

Hi,

So I finally managed to finish the file sync plugin so I you can see 
what I mean.

The prototype is at https://github.com/porvik/kdeconnect-kde/tree/sync

Of course there is still a lot of stuff to fix / implement e.g.:
* proper plugin level configuration - files, logs, mount paths etc
* unidirectional sync
* more safety checks (paths, existing folders, validations)
* asynchronous copy / script execution
* Android notifications and the actual app
* etc.

I you plan to run it probably need to edit common.h general section, 
i.e. mount root, etc.
and to actually run it just send a ping from the android (app is missing 
still).

Said all that, my idea is not to replace any full fledged sync SW but 
rather to make it an extra feature with limited but features. I also 
checked the existing code 
(https://cgit.kde.org/kdeconnect-kde.git/log/?h=filesync) and the main 
difference is that data is transferred as a network packet payload 
unlike me, since I have static configuration and I use SFTP plugin.

Also about the "File access" I am not sure I know what it means so ..?

Please tell me what you think and explain if the "File access" if possible.

Thank you,
BR,
Viktor

    I think there are better file synchronization software out there
    than KDE Connect ever could be, it's simply just a lot of work, take
    a look at Syncthing if you need something free. File access is
    another topic though (really appreciate that feature).

        Hi,

        file syncing is something that has been requested several times
        and it would allow some nice use cases. There is some old work
        on it on the desktop side
        (https://cgit.kde.org/kdeconnect-kde.git/log/?h=filesync) but
        there is no code for Android yet. I also had the idea of
        leveraging the SFTP plugin for it, but I'm not sure if that's a
        good idea since it's a bit unstable.

        If you have some PoC code please share it with us so we can
        discuss it further.

        Cheers

        Nico

            Hi,

            I am using kdeconnect on openSUSE and find it very useful
            app. I have following two use cases that I have solved but I
            was wondering about more elegant solution (and if it would
            be worth it).

            First I have an encrypted pw safe data (and possibly some
            other private data) that I have on my phone, desktop,
            laptop. Once in a while when I create new entry or edit an
            existing one I update the pw safe db and I need to copy that
            manually between all devices. Depending on a frequency that
            might be quite often. For security reasons I dont use cloud
            and everything is offline only copied over USB or private
            wifi. To facilitate I was thinking to make shell scripts
            that will do the job and use it trough execute command
            plugin but I find that very specific to the problem.

            Second use case would be photos. I am often taking photos
            (even have private cloud backup) but I would like to have
            all photos downloaded / synchronized to set folder on my pc,
            and even possibly to execute some post copy - processing
            shell scripts once all photos are downloaded e.g. conversion
            of photos, resize, upload to gallery.

            I was thinking to write stuff just for myself (or just keep
            it as shell scripts) but then I was wondering whether it
            would be maybe a good idea to make it more generic? I was
            considering to implement it a plugin. The issue is that tt
            would be depending on sftp plugin which creates dependency
            not only on a base app.

            I would have an initial idea (even have a crude prototype)
            and I have some more technical questions if it turns out to
            be a good idea. I am new to D-Bus stuff and I find it pretty
            interesting, so please any comments are welcome.

            Thank you,
            BR,
            Viktor
