serious regression: whole layer not rendered (when simplify geometry activated) #17960

qgib · 2014-01-16T19:38:49Z

Author Name: Mathieu Pellerin - nIRV (Mathieu Pellerin - nIRV)
Original Redmine Issue: 9360
Affected QGIS version: master
Redmine category:vectors
Assignee: Martin Dobias

A very serious regression has made its way into QGIS master following the (2nd) simplify geometry commits. Whole layers end up not rendering when zooming in / out.

Steps to reproduce:

Open the attached error.qgs project (which contains two shapefile layers with same points in different projections)
Using mouse wheel, zoom in and out and give it a few seconds before each zoom step
Notice how the green points layer goes missing (~50% of the time) when canvas is rendered following zoom action

Disabling [ ] simplify geometry option fixes the serious regression.

Alvaro, that was fast :)

I don't have a build environment ready to test patch :/ can certainly verify when its commited. Looking at your patch code, I should add that I also see the layer-not-rendered issue with polygon layer too. Is the patch covering this case too? If not, I can come up with a simple project to reproduce issue.

Glad you can fix this. Beyond the above issue, your 2nd series of simplify geometry commits are having a drastically positive impact.

Alvaro, the first project attached to this issue works much, much better with your patch applied (although I can still make the green dots layer disappear if I zoom out to extreme values).

It has however not dealt with disappearing polygon layers (or at least not taken care of all the cases). I've created another test project that shows this quite well: http://www.licadho-cambodia.org/error2.zip (it's >30mb, couldn't attach to this ticket). On my screen, when I open the project, the forest cover polygon layer simply doesn't render. It might show on yours depending on your main canvas size. Zooming in and out a few steps will get the layer to disappear just like with the points example.

I'm re-opening this case as further work is needed.

Hi Alvaro,

i haven't tested the lats patch, but with qgis master just compiled from source I see a strange behaviour when the "simplify on provider side" option is checked, and the vector is a shapefile. On the other hand it works ok with postgis, see attached images.

Thanks in advance!

Hi Mathieu, I see the layer disappear for scales ~1:1.161.063.094, now the simplification is never applied for point layers and I think that it occurs because of other error.

When a layer is rendered, the current map extent is transformed to layer coordinates (using the CRS of the layer), this transformation for so big extreme scales returns empty and any geometry is fetched to be drawed. The error occurs https://github.com/qgis/QGIS/blob/master/src/core/qgsmaprenderer.cpp#L414.

I think this error is not caused by my patch, you may please disable simplification and verify the layer disappears?
If it is true, we can open one specific issue to fix it

Thank you very much!

I think we should close it when the polygon layer not rendered issue is fixed (which occurs when simplify geometry is activated). For the other issue that has nothing to do with simplification, I'll file a proper ticket so we can close this one when above problem fixed.

Hi Mathieu, polygon layer disappear even with simplification disabled. I have tested with QGIS before simplification changes and same behavior.

The project uses 'on the fly' transformation (ESPG:3148 -> EPSG:4326), disabling this transformation the layer appears. Can you confirm it please ?

Thanks!

Alvaro, the layer gone missing is definitively linked to on the fly reprojection between ESPG:3148 (meter-based) to EPSG:4326 (degree-based); that said, on three linux machines I tested, when simplification is disabled, the polygon layer never disappears.

The three machines all run Ubuntu 13.10 and uses the QGIS master packages offered @ qgis.org/debian-nightly. Those packages are compiled with:

Qt 4.8.4
GDAL (compiled) 1.9.0 (running against) 1.9.2
GEOS 3.3.3-CAPI-1.7.4
PROJ.4 470

Giovanni, tested using which QGIS version / master build? Windows or linux? As I said, I can reproduce all the time on three linux machines.

Hi Mathieu, to try reproduce the error, please can you send me the situation on the map? (windows size, map center point, and map scale) and as the simbology of the layer is defined.

Thanks in advance

Mathieu seems to think I can get the error with this data http://www.licadho-cambodia.org/error2.zip.

What I'm seeing is that when the data complexity changes in a hurry the entire canvas goes blank for bit while the rendering catches up with the zooming.

The most reliable why I can do it is to zoom in to a reasonably complex bit, say 105.66267 13.48494 at say 1:10000. Then zoom out quickly - mouse wheel it.
On my work computer (win7-64bit osgeo4w 121d647354) five wheel stops in about a second will do it fairly reliably.
With this data I do get it at other times, but that's the most reliable. It does seem possible to do it without using the mouse wheel too - but is much harder because QGIS waits a bit before letting me zoom again.

I'm not sure this will help, but I'd describe the symtoms a bit differetly than above, so maybe it will.

Thanks Ramon, I can reproduce this behavior in QGIS 2.0 Dufour and master before simplification was merged.

When user changes the visibility of layer while it is being rendered and repeatedly user changes the zoom with mouse wheel, then the layer disappears or it is rendered even with visibility disabled.

I had already seen before simplification was merged. Can you confirm it please ?
Recently I tested the multi-thread rendering branch of Martin Dobias and these issue work fine.

Note:
I think that #18041 describes the same issue

I've recorded a video of the issue, which hopefully might do a better job than my words at explaining the problem; it's here: http://licadho-cambodia.org/bug.webm (10mb)

Towards the end of the short clip, you'll clearly see that every time I activate simplify geometry, the layer goes missing, and vise versa.

I can reproduce super easily at scale 1:1,597,047 and 1:940,642 (and a bunch of other scales)

Alvaro, the log window doesn't throw any error message.

Yes, please, try on linux / ubuntu 13.10, it does seem to be part of the "recipe" to get to this issue. Which could mean the bug is triggered by a different version of the underlying libraries QGIS make use of, or display driver (my three machines have NVIDIA video cards).

Hi all,

I use ubuntu 12.04 (intel video card), qgis master from nightly build repo + ubuntugis (gdal 1.10), simplification active, and I can't replicate the described issue (even trying very hard) with the attached sample project/layer.

Still not sure if its the same bug, but tracks.zip file is giving this error on the mint terminal at home:

ERROR 1: IllegalArgumentException: point array must contain 0 or >1 elements

Would say it's something to do with odd geometries from a gps track - except that I had it in a different workspace today where it worked fine.

Hi Mathieu, I successfully built QGIS master in Ubuntu 13.10 :-)

I use VirtualBox in Windows XP 32bits.
Thanks Nyall, your note about 'libpython2.7.so' (http://nyalldawson.net/2013/04/building-qgis-on-ubuntu-13-04/) was very useful to me.

But I can't replicate the described issue (shapefile from error2.zip) :-(
May be a plugin ?
What else I can do?

If it's not happening then, I give up :/

I have also tested extensively qgis master installed on ubuntu via ubuntugis, self compiled and on windows/osgeo4w and I cannot replicate the issue with the provided test project/data.

I will close this ticket for now, we need to clean the blockers queue before the new release.

If you find the issue to be not a local issue (as it probably is) please reopen this ticket.

Hi Mathieu, I can replicate this issue in my Virtual Box with Ubuntu 13.10 + qgis debian-nightly package. But I have no idea how to debug this, source code, IDE to use ... sorry. I am newbie in Ubuntu, I do not even know where to begin. I will try to locate information.

you can replicate the issue if through debian-nightly compiled QGIS builds

You are right, but I do not know how to solve it. I guess I should use QtCreator or Eclipse-CDT to build QGIS, but where is the source code for 'http://qgis.org/debian-nightly' repository ?

The guide describes multiple paths. Just to be sure: You used "3.8. Building Debian packages":http://htmlpreview.github.io/?http://github.com/qgis/QGIS/blob/master/doc/INSTALL.html#toc11 (that you ran into the @libpython2.7.so@ problem suggests that you didn't).

I've just upgraded by system to ubuntu's upcoming trusty 14.04 system. The debian-nightly packages are still affected by the regression.

However, if I manually compile QGIS from the same source tree, the regression is gone. Same packages, same source revision. I'm lost here.

Hi, sorry no answer, these days I'm finding it impossible to look for family reasons. I built QGIS in Ubuntu 13.10 using ccmake as described in http://htmlpreview.github.io/?http://github.com/qgis/QGIS/blob/master/doc/INSTALL.html#toc10. It works fine.

But installing debian-nightly packages as described in http://www.qgis.org/en/site/forusers/alldownloads.html, it works wrong.

The about dialog using debian-nightly packages (Apparently are equal):

!Ubuntu_13.10-debian-nightly.png!

When I built QGIS using ccmake, I configured libpython2.7.so as described in Nyall in http://nyalldawson.net/2013/04/building-qgis-on-ubuntu-13-04/ ...

'Update: a better solution is to change the PYTHON_LIBRARY option from /usr/lib/libpython2.7.so to /usr/lib/x86_64-linux-gnu/libpython2.7.so'

it is weird because I use the nightly build repos on Ubuntu 12.04 (mint actually) and I can't replicate the issue.

Should we reopen this? if it is confirmed by others using the official packages this could be a problem in the upcoming new release.

Martin, out of purely geeky curiosity, why was this not showing on self-compiled builds and showing on the debian-nightly packages?

Actually, I have replicated the problem by chance while playing with #17707 on my self-compiled build (not using debian-nightly at all).

I don't know how much the debian-nightly packages differ from your own build, but it could be compiler version or maybe some compiler flags...

This is kind of a random bug that waits in the dark corner and usually strikes just after the release :-)

ufff, Thank you very much Martin, this type of error I would not have ever found!
