Hi Kory,

Maybe this related to issue https://hub.qgis.org/issues/14255
That issue is still open.

That sounds all good.

I think the main reason the topic was brought up was that it's one of
the few blockers which are still open.

Let's split it into two issues:

 Moving to a background thread, that's probably a feature request, so we
could just downgrade that to a "hight" priority one.

 For the endless loop, we can leave that as blocker (in the end you have
to kill the app, so it's like a crash with lost unsaved work).

I'm on Debian Testing;

I do not have a clean install available, but if I start qgis from
commandline here with a fresh config:

qgis --configpath /tmp/foo

I end up with two items in the svg path:

/home/richard/apps/qgis/master/debug/share/qgis/svg/
/tmp/foo/svg/

The first one is the svg directory of my installation (self compiled),
the second is a svg directory in the configpath (which is your home dir
by default I think?)

Regards,

Richard

Hi Nelson, 

Thanks for checking. 

Are you sure the users home directory is added to the SVG paths by
default on Debian? I can't confirm this on Ubuntu. 

I thought that by default this setting is empty. 

It would be a really unfortunate default value to add the users home
directory to the SVG paths by default.

I use Debian (one machine with testing and another with unstable; both
version are 2.14.3) and I never set any search path.
But what I see is that both have a common path already configured: my
home (see https://i.imgur.com/9ucjAwA.png for an example).

I think that two things could be improved here:
1) have an empty list by default (ie, don't set the user home as a search path)
2) have an option to enable/disable recursion in the specified paths

For item 2, suppose the user has this directory structure:

/home/user/SVG
/home/user/SVG/scratch

He wants to use the SVG files inside "/home/user/SVG", excluding
everything from the scratch dir.
If he sets "/home/user/SVG" as a search path, everything in scratch
will also be included.

As it is now it seems that it's not possible to restrict a recursion
like this (ie, everything in a specified path will always be fully
traversed).

Hi Nelson, 

Thank you for your feedback. 

Hm - but you are not supposed to provide a path with multiple gigabytes
of data to browser for SVG files. Of course this would be slow. Every
photo manager takes a long time if it has to browse the whole disk for
photos. This would be a misuse of this setting. 

This setting is meant for you to provide a handful of smaller
directories reserved to hold SVG files for QGIS - not to search the
whole hard drive - lets say not more than a couple hundred files at
maximum. 

The question is how this works for Debian users under "normal"
conditions, where you don't specify your whole home drive as a search
path.

If I properly understand the problem, it seems that QGIS, by default,
traverses the user home looking for SVG files.
And indeed, depending on the size of the home it takes some time (and
QGIS stays blocked while it doesn't finish this).

Have a home with 346G (like mine) and you should see what happens.

I don't know how it's made, but maybe this traversal could be
implemented asynchronously or using a thread? (so the main process
won't get blocked while searching for SVG files)

Hi, 

Are there any Debian (or Ubuntu) users out there who can reproduce this
bug here: 

http://hub.qgis.org/issues/14255 titled "SVG preview blocks QGIS". 

If it is only Paolo experiencing this issue and noone else, I would
suggest to close this bug as not reproduceable. 

Thank you for your feedback,
