Do not constantly rewrite info-* files

[Nazar Mokrynskyi]

I have xpad config directory under ownnCloud and realized that this file being constantly rewritten.
Is there any chance to make this behavior sane and update file if only something is changing? Because currently looks like it is updated every X seconds or whatever by timeout repeatedly.

What version of Xpad are you using?

[Nazar Mokrynskyi (nazar-pc)]

4.5 from Ubuntu 15.10 repository

Thanks for the input.

A developer needs to analyse this, so this might take some time.

For now, thanks for reporting.
Your issue is on the bug list.

[Nazar Mokrynskyi (nazar-pc)]

Thanks, feel free to ask me any questions if there will be any need for that.

Hi Nazar,

Xpad should only save information if text on the pad has changed, or any of the settings/events have changed.
It queues all these changes and auto saves them each 4 seconds.

How did you notice or measure that Xpad doesn't behave like above?

[Nazar Mokrynskyi (nazar-pc)]

Each time I switch virtual desktop Xpad rewrites its info files, while certainly nothing related to Xpad was changed.
I've made info file read-only to check this.
How to reproduce: make info file read-only, switch virtual desktop, wait 4 seconds and here you are.

Confirmed on Ubuntu 15.10 with Xpad 4.5.
Thanks for the explanation

[Arthur Borsboom (arthurborsboom)]

After analysing this behavior, I guess this seems to be by design.

When changing from workspace 1 to workspace 2, Unity moves the pad from location x to location x-900 (for example).
Since Xpad keeps track of the location of each pad, it does save this change. In this way, the next time Xpad starts, it will show the pad on the correct workspace.

The autosave feature of Xpad is quite cool, since this way the chance of losing information is small.
However, autosaving the location of a pad (metadata) is by far not as important as the information in the pad (data).

So, I wil make a design change in favor of performance and choose to only store the location information on disk when shutting down/exiting Xpad. How does that sound?

[Nazar Mokrynskyi (nazar-pc)]

Sounds great, I'll test it as soon as it appears in xenial-proposed.
Thanks for fast response BTW:)

When will this be upstreamed? Still suffering from this on Ubuntu 16.04.

[Arthur Borsboom (arthurborsboom)]

I am not sure. In general I have a hard time getting newer versions of Xpad
into the repositories of Linux distributions (except for Arch).
Maybe you can do an inquiry at Ubuntu or create a bug report (request) for
updating the Xpad in the Ubuntu repositories?

Out of curiosity, I would like to know how this progresses...

Here it is: https://bugs.launchpad.net/ubuntu/+source/xpad/+bug/1525656
I'm wondering you're not a maintainer of Ubuntu's xpad package, let's see who will answer (if anyone) there.

[Arthur Borsboom (arthurborsboom)]

Alright. Let's see what happens... :)
