Loading PostGIS native rasters through DB Manager is slow but effective. When loading an out-of-db (registered through -R option of raster2pgsql), I get a crash with current master:

Duplicated by QGIS Application - Bug report #16754: QGIS crahes when panning or zooming PostGIS raster Closed 2017-06-25

History

#1 Updated by Jürgen Fischer over 8 years ago

Doesn't crash here. But still doesn't seem to work. I get plenty of "RasterIO error: IReadBlock failed at X offset 0, Y offset 0" in the message log. And gdal_translate says "ERROR 1: This raster has outdb storage. This feature isn't still available" - I suppose GDAL (as of 2.1) doesn't support this yet.

#2 Updated by Giovanni Manghi almost 8 years ago

  • Status changed from Open to Feedback
  • Crashes QGIS or corrupts data changed from No to Yes

Please update the status of this ticket on latest qgis releases.

#3 Updated by Paolo Cavallini almost 8 years ago

Currently impossible to test because of #15910

Paolo could you test again with a build from the release-2_18 branch ?
Also, can you attach data and script to reproduce ?

#9 Updated by Paolo Cavallini over 7 years ago

Unfortunately I'm currently unable to add -R rasters, so I cannot reproduce the issue.
I'll try again.
Sorry.

#11 Updated by Paolo Cavallini over 7 years ago

Confirmed with 2.18.7.
I did extensive testing, but I cannot replicate it reliably.
What I did:

 raster2pgsql -s 3003 -I -M -C -R /home/paolo/dtm.tif > dtm_ext.sql
 \i dtm_ext.sql

Then loading in QGIS, zzom > crash.

Data available: http://www.faunalia.eu/~paolo/dtm.tif

I have also:

Warning: RasterIO error: PostGISRasterDataset::LoadSources():

#12 Updated by Giovanni Manghi over 7 years ago

  • Status changed from Feedback to Open
  • Subject changed from Crash when loading PostGIS external raster to Crash when loading PostGIS raster
  • Category changed from Rasters to Data Provider/PostGIS
  • Affected QGIS version changed from 2.18.4 to 2.18.7

with the same data, on 2.18.7 it also crashes even if the raster is loaded inside the DB. Loading as "external" does not seems the factor here.

I'll try reproducing this today.

#14 Updated by Sandro Santilli over 7 years ago

Paolo I can load the raster and zoom in and out w/out a crash being produced.
This is with current release-2_18 branch (cea93faa252db67ec007849bad9a7a070dd27b2b targetting 2.18.9) and
POSTGIS="2.4.0dev r15405" GEOS="3.7.0dev-CAPI-1.11.0 8fe2ce62" PROJ="Rel. 4.9.3, 15 August 2016" GDAL="GDAL 2.3.0dev, released 2017/99/99" LIBXML="2.9.4" LIBJSON="0.12.1" LIBPROTOBUF="1.2.1" TOPOLOGY RASTER

What version of GDAL are you using ?
Can you reproduce with a more recent one ?
The one I'm using is r38596 (which gives libgdal.so.20.1.2, while yours is libgdal.so.1)

Is the WARNING you get giving any more info ?
Warning: RasterIO error: PostGISRasterDataset::LoadSources():

I had indeed even recently #8073-12
To make my tests I use only clean boxes (usually VMs) with no compiled software, all from the official repositories.

#17 Updated by Sandro Santilli over 7 years ago

  • Assignee deleted (Sandro Santilli)

Unassigning as it works for me with latest GDAL from master and the backtrace from Paolo seems to indicate the problem is within GDAL (I guess pgraster driver).

Panning or zooming a map with a PostGIS raster works fine here in QGIS 2.99.0 master (313ec55).

that is a good news! any chance to have the dataset shared as also the exact command you used to load them into postgis? I would like to replicate in the most similar conditions as possible. Thanks!

Hi Giovanni, you can find the .tif file and the raster2pgsql command here: #16754 (duplicate).

  • Affected QGIS version changed from 2.18.7 to 2.18.13
  • Status changed from Feedback to Open

I assume this

https://lists.osgeo.org/pipermail/qgis-developer/2017-September/049806.html

was on 2.18.12 or .13 so bumping the affected version.

#24 Updated by Martin Gutwin about 7 years ago

I have a similar situation as described in #16754 (duplicate) and was also able to replicate the issue there. My QGIS version: 2.18.13. PostGIS is 2.3.3 from ubuntugis-unstable with GDAL 2.1.1.
An interesting behaviour I observed is: as long as I zoom by only 1 step at a time (Zoom tool or turn the mousewheel by only 1 click), everything works fine. As soon as I spin the mousewheel more than one click, QGIS crashes. Can anyone with the error try to replicate that?

Another weird thing happens when I try to load my raster in QGIS (original file: Sentinel 1 GeoTIFF ~700MB, ingested to PostGIS without errors and with these options: raster2pgsql -I -C -e -Y -F -s 0 -t auto -l 2,4).
When I try to load it directly after QGIS-startup, QGIS crashes. When I first load any other layer and then load the DB-raster, it "works" in the same way I described above.
Any ideas?

If you need logs or videos, please provide me with instructions, because I am new to bug tracking.

I think that the situation is pretty much clear: postgis rasters are not (still?) not well supported.

#26 Updated by Paolo Cavallini over 6 years ago

True. This seems an important functionality missing.

#28 Updated by Even Rouault over 6 years ago

Support for out-db postgisraster has just been added in GDAL master, and been backported to GDAL 2.3 branch for GDAL 2.3.1, so the main issue reported here will be fixed once QGIS use it.

This ticket has somehow been 'hijacked' with other issues related to crashes in other contexts, which I can't replicate. I've tried with the data and ingestion procedure described at https://issues.qgis.org/issues/16754. I presume this might be due to some bugs in older GDAL versions fixed since. I suggest we close that issue, and, if needed, more focused issues are opened with dataset + GDAL version + exact raster2psql invokation used
