[Qgis-user] QGIS Master dependency problem.
QGIS Master from the nightly repository, Ubuntu 12.04 (amd64). Hi All, There were problems with this morning's upgrade (and yesterday's too) with python-qgis-common and python-qgis: pycentral: pycentral pkginstall: error byte-compiling files (549) pycentral pkginstall: error byte-compiling files (549) dpkg: error processing python-qgis-common (--configure): subprocess installed post-installation script returned error exit status 1 dpkg: dependency problems prevent configuration of python-qgis: python-qgis depends on python-qgis-common (= 1.9.0+git20130618+59fd5e0~precise1); however: Package python-qgis-common is not configured yet. dpkg: error processing python-qgis (--configure): dependency problems - leaving unconfigured No apport report written because the error message indicates it's a follow-up error from a previous failure. Errors were encountered while processing: python-qgis-common python-qgis E: Sub-process /usr/bin/dpkg returned an error code (1) Regards, Nick. -- View this message in context: http://osgeo-org.1560.x6.nabble.com/QGIS-Master-dependency-problem-tp5061716.html Sent from the Quantum GIS - User mailing list archive at Nabble.com. ___ Qgis-user mailing list Qgis-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-user
[Qgis-user] Projects with too many rasters
Hello, Found an odd problem, but if your project has a few vector layers and a large number of rasters covering the same area, then it seems that after a certain number, not sure how many, but the vector layers at the top of everything no longer remain visible. Put simply, if you have a coastline layer at the top, overlying everything, and add more and more rasters, eventually it gets buried by the rasters. I am using 1.8.0 and have seen this problem a number of times with the layers - tried re-ordering and putting the vector layer to the front again, but no joy. There does appear to be a bug with visibility if too many coincident rasters are loaded. I basically have to create separate projects for certain raster/vector structures now to get around this. Has anyone else seen this issue? Cheers Lester ___ Qgis-user mailing list Qgis-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-user
Re: [Qgis-user] questions about the FOSSGIS 2013 benchmark comparisons between QGIS Server and UMN Mapserver
It is important that you test QGIS master not QGIS 1.8. QGIS 1.8 was definitely slower than UMN, but in master there are performance improvements in the server part. Marco knows the details. There have been a lot of performance improvements in QGIS core (e.g. the new raster system, svg cache, more performant coordinate reprojection, CRS and Coordinate transform cache, project file cache, ...). Nore that the benchmark especially measures the scalability of the WMS server (many concurrent requests). For scalability, it is important that as much is CPU-based and data comes from RAM rather than from disk. While a desktop user e.g. does not notice a request to the sqlite DB to lookup a CRS definition, this small disk access had a big impact on scalability. Similarly for SVG files, project files, coordinate transformations. All these things are cached now on first usage.

I was surprised to see how QGIS Server outperforms UMN Mapserver, because my experience was different. I haven't done comparisons in the last months. In the past performances didn't appear better then Mapserver. Marco (and the ohters from Sourcepole), could you share the configurations adopted for the benchmark? Hardware, http server configuration, caching, tiling, etc.? Something is written inside the PDF, but Google Translator isn't doing a great work :( Thanks a lot, Giovanni [1] http://sourcepole.ch/assets/2013/6/17/fossgis_2013_performanceoptimierte_wms_dienste.pdf [1] -- Dr. Marco Hugentobler Sourcepole - Linux Open Source Solutions Weberstrasse 5, CH-8004 Zürich, Switzerland marco.hugentob...@sourcepole.ch http://www.sourcepole.ch Technical Advisor QGIS Project Steering Committee ___ Qgis-user mailing list Qgis-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-user
