It looks like the backport never happened, but merkaartor (0.18.1-3) 
has

been in Debian since wheezy.

Is this issue still relevant?


Apparently yes, at least in Jessie (and Wheezy, of course).
Zooming in through the "100 m" scale makes the machine extremely slow,
although there are close to no objects to be handled (and background 
images

are turned off).
With Bing imagery on, this zooming tends to kill Merkaartor.


What are the specs of the machine in question?

It may just be that my machine is powerful enough to handle the amount 
of data and rendering thereof.


Or it may be specific to the area your working in. How can I reproduce 
your issue?


Since I cannot reproduce this issue with the current merkaartor 
version

in unstable (0.18.1-3+b7), I'm tempted to close this issue as fixed.


Is there a backport I can try with Jessie? I don't like bugs being
closed when there's no solution for stable...


There is nothing to backport yet, merkaartor 0.18.1 is in wheezy, jessie 
& stretch.


Once merkaartor 0.18.2 has migrated to testing I'll likely provide a 
backport for jessie, but I'm not done yet triaging the outstanding 
issues, so merkaartor 0.18.2 is only available in experimental 
currently.


We need merkaartor 0.18.2 because it has GDAL 2.0 support upstream, 
that's prominent blocker for the GDAL 2.0 transition I'm working to 
resolve with my contributions to the merkaartor package.


Kind Regards,

Bas

Netbook, 4 years old, 2GB RAM, Intel dual-core Atom N450 @ 1.66GHz,
but also seen on a "Intel(R) Core(TM)2 Quad CPUQ9550  @ 2.83GHz" with 4GB

The problem is that there is almost no data to be rendered (Ethiopian
desert)

This is my bookmark. There are two power lines "ending" in the area,
try to find the next towers by guessing their locations and zooming
around.
With 200m or even coarser all ist fine and fast. Try to go down to
50m and feel the sluggishness:

But apparently the behaviour has changed between wheezy and jessie
(no more dirty opbjects after upload), so they aren't identical?

Is there a backport I can try with Jessie? I don't like bugs being

Hi Steffen,

Thanks for the additional information, I'll try to reproduce the issue 
in the area where you encounter it.

There is nothing to backport yet, merkaartor 0.18.1 is in wheezy,
jessie & stretch.


But apparently the behaviour has changed between wheezy and jessie
(no more dirty opbjects after upload), so they aren't identical?


No, they aren't identical. They have been (re)built with different 
versions of their dependencies (the ones available in the release in 
question). The source package is still identical, the binary packages 
use different (versions of the) dependencies.


Kind Regards,

Bas

Yes, I noticed that (and downloaded the latest versions from the pool).
Unfortunately, libgdal1-1.7.0's dependency on libmysqlclient16 looks incorrect,

You just might want to stick with a stable release and install the
backport I'll provide in a few dayhs.

Bug#614783: merkaartor: Merkaartor becoming sluggish after zoom operations

[Steffen Grunewald]

Package: merkaartor
Version: 0.17~rc4-1
Severity: normal


I have found that when heavily zooming in and out while working on an area
of moderate size, Merkaartor becomes more and more sluggish, in particular 
when drwaing ways or panning.
This didn't happen with versions before 0.17, and doesn't seem to correlate
with the number of changed objects but the number of zoom operations.
top output doesn't look suspicious (but I have to change workspaces
to check).
Any details I can provide?

I'm afraid a few dependencies will force me to upgrade to testing first;

I guess I had picked it from the pool (not checking which release it belonged
to, only trying to get Bing support). Files are dated Dec 14.

 If you've installed it from experimental, you might have a bad mix of  
 packages already.

May have been experimental, but since it didn't need any new dependencies
in pre-release squeeze, I didn't worry.

 I'll provide a backport as soon as 0.17.2 is in testing.

Too late... I'm running wheezy now. No risk, no fun, but I've been looking
at Joey Hess' CUT project, and that might be close, I hope.

 S
