Description
Hello,
I have a geoserver running on localhost. In QGIS, establishing the connection via the "Create new WFS connection" panel works, but when I then try to add a WFS layer to QGIS I observed a strange behavior. Sometimes after the first or second wfs layer added to QGIS, QGIS freezes completely and I have to restart it. Sometimes I can add more layers but at some point it will freeze again. Also object loading of large layers is very slow.
All these problems did not occur in QGIS 2.18.
Can anyone reproduce this or has similar problems with the WFS provider in QGIS 3?

Can you provide any public WFS address that we can use to replicate this behavior?

Unfortunately I can't, because with public/ external WFS servers I encountered no problems. Only when working with a WFS from a geoserver on localhost the problem occurs, and only in QGIS 3, whereas in QGIS 2.18 everything worked fine, as mentioned. So maybe anyone else with a local setup of geoserver and QGIS 3 also encounters this problem...?

Can you describe a little what kind of data (size, datasource type, etc.) your local service is based on?
What version of Geoserver are you using? Installed with what method?

I can verify these same issues connecting to my local geoserver serving WFS files. This only appears to effect Mac and Linux installations however as Windows seems to be ok. We are running all three OS in our office. There was another bug report here that offered a public WFS file for testing. I'll see if I can find it and post it.

Yes, it's just as Willem Buitendyk describes it, on Windows the problem does not occur. On Linux, it happens with all kind of basic vector layers from the geoserver wfs. I tried with several geoserver version 2.11, 2.12, 2.13, installed within a docker environment and without docker, and the problem always occurs.
Appearently, when the freezing occurs, a describeFeatureType request get's successfully sent to the geoserver. But then QGIS never send's the getFeature requests and get's somehow stuck in processing the wfs service responses.

It happens only with Geoserver (what about Mapserver or QGIS Server)?
Only with local installations?

Yes, it's only with Geoserver. I didnt't try out Mapserver and QGIS Server, because I don't have them installed. And yes, it's only with local installations. I'm sorry that I can't specify the problem further, but since QGIS freezes (until I kill the process) I also could not find any log messages. Do you have an idea how I can log the WFS provider communication to see what actually happens, when QGIS crashes/freezes? Then I could provide more information here.

would you mind give it a try, using the very same datasources you are using for the local Geoserver?
And yes, it's only with local installations.
so, two Geoserver instances, one local and one remote (same local network? over the internet?) and same datasources, and only the local one fails, correct?

not sure this is related
https://github.com/qgis/QGIS/pull/7602
but seems so. Test it on master when merged, then report back. thanks!

Thank you for linking the PR. It looked promising, but I tested today and unfortunately the bug continues. By installing the qgis-dev version I could track down the problem further: If I set back the file https://github.com/qgis/QGIS/blob/master/src/providers/wfs/qgswfsrequest.cpp to it's state of QGIS 3.0, i.e. before the introduction of multithreading, I have no problems at all! But with the current version, when performing wfs request on my localhost geoserver, the code gets stuck in lines 194 to 214 of the mentioned file, where the "downloaderThread" never finishes.
Could we maybe assign Matthias Kuhn to this issue, as it looks like he introduced the multithreading to qgswfsrequest?

let the developer know by commenting on github (in the commit page, or even commenting at the lines you say above).

If you've got a self compiled qgis version, can you:
1. Make sure it's a debug build
2. Run through gdb and interrupt when you get the hang (ctrl C)
3. Get a full back trace of all threads via "thread apply all bt"
Post that here

Updated by Nyall Dawson about 6 years ago
Thanks! Can you repeat with latest master (or 3.2 branch master) and post a trace from that build?

Updated by Jonas Grieb about 6 years ago
