Bug report #16067

Geometry checker crashes/seg fault

Added by Giovanni Manghi about 3 years ago. Updated about 3 years ago.

Status:Closed
Priority:High
Assignee:Sandro Mani
Category:C++ plugins/Geometry Checker
Affected QGIS version:2.14.10 Regression?:No
Operating System: Easy fix?:No
Pull Request or Patch supplied:No Resolution:fixed/implemented
Crashes QGIS or corrupts data:Yes Copied to github as #:23982

Description

Use the attached dataset with the provided configurations (see screenshots):

once fixed the auto-intersection the table/resume with fixed problems and new ones is shows (notice that under Linux/kde the list of new/unsolved problems is empty, while it seems to look as expected under Windows).

If the user then clicks on one of the records/rows representing the new/unfixed problems it gets instant crash.

Tested on 2.18.2 on kubuntu 16.04 (qgis from repos) and on Windows under 2.14.10 and 2.18.2.

History

#1 Updated by Giovanni Manghi about 3 years ago

actually on Windows the crash is instant right after pressing "run".

#2 Updated by Sandro Mani about 3 years ago

Looks like something regressed here... I'll investigate.

#3 Updated by Sandro Mani about 3 years ago

  • Status changed from Open to Closed
  • Resolution set to fixed/implemented

Actually this was already patched in master half a year ago but didn't make it into 2.18... Backported

#660df4ac57f444c67a3e190247250a0928db8eae

#4 Updated by Giovanni Manghi about 3 years ago

Hi Sandro, thanks!

it will also be backported to 2.14?

#5 Updated by Sandro Mani about 3 years ago

2.14 has an earlier version of this patch so should not suffer from this crash.

ummm... but it does, at least on my test (see above).

#7 Updated by Sandro Mani about 3 years ago

let me check that

#8 Updated by Sandro Mani about 3 years ago

What rev are you using? Testing with f4d9514c1d1e7bf13b3bc1cba570ba9996f3ebf3 it works fine AFAICS, i.e. no blank entries in the results table.

Hi Sandro,

the blank table entries are only on KDE/Ubuntu, qgis 2.18.2 rev 102ee87

I cannot test other DE now.

The crashes are also on Windows with QGIS 2.14.* (tested different point releases, included .3, .7 and .10)

#10 Updated by Sandro Mani about 3 years ago

So on windows it crashes when selecting one of the newly added errors (i.e. the gaps)?

no, it crashes when hitting "run".

#12 Updated by Giovanni Manghi about 3 years ago

Confirmed the crash on "run" on Windows with qgis 2.14.11 64bit installed with osgeo4w.

#13 Updated by Giovanni Manghi about 3 years ago

  • Resolution deleted (fixed/implemented)
  • Affected QGIS version changed from 2.18.2 to 2.14.10
  • Target version changed from Version 2.18 to Version 2.14
  • Status changed from Closed to Reopened

Sandro I'm reopening because (unless I'm wrong) this should be fixed also on ltr.

#14 Updated by Bogdan Hlevca about 3 years ago

On Linux, all my versions crash with this error. I tried the official OpenSuse 42.2 builds: master/2.18/ltr and my own builds: master/2.18.1/2.18.3 branches.

I don't think I changed anything in the qt4 environment.

#15 Updated by Sandro Mani about 3 years ago

Uhm, even latest 2.18 with f4d9514c1d1e7bf13b3bc1cba570ba9996f3ebf3? If so, can you give more details steps to reproduce or a backtrace?

#16 Updated by Bogdan Hlevca about 3 years ago

Unfortunately, there is not much to be said except that I should build it in debug mode to capture more output.

The crash happens on startup. I tried to remove the plugins and the .qgis/ but it did not make a difference. I am o KDE platform with the newest QT5 which may interfere. I tried to build the QT5 version. Actually in master I could build only in Qt5. That crashes with no trace so it is even worse.

I tried to compile now 2.18 and I cannot. it complains abouterror: ‘sipName_QString’ was not declared in this scope.

I see that other people complain about it [[https://aur.archlinux.org/packages/qgis/]]. It appears that it is sip related and I don't think that I can downgrade anything. I guess I am stuck of not being able to use QGIS for a while.

I will try to build again in Debug mode and see if I can get you more information. I can send you a 'ltrace` run see below:

Is your segfault actually related to the geometry checker?

#18 Updated by Bogdan Hlevca about 3 years ago

I am not sure. It happens at startup. This may be the wrong place to report it, but I found it based on the crash reports. I believe that there is a sip related problem.

#19 Updated by Sandro Mani about 3 years ago

So this is most definitely not this (or even a) geometry checker bug. Please have a look at the description of the issue to ensure the information you post is actually relevant.

In your case you should use gdb to gather a stack trace and then report a new issues with that information. Without a stack trace, it is near impossible for people to help you since "crash on start" is way to vague.

Concerning the sip problem in particular: the recently released sip-4.19 removes a number of methods which have been marked deprecated for a number of years. Some of these methods are still used in recent qgis 2.x releases, hence the build failure. I've a work-in-progress patch here [1] which should get most things building except an issue with the qgis-server code I haven't yet managed to figure out how to fix.

Sandro, I will try to get you the stack trace from Windows crash (that I have no idea how to get it, but I will try). But the description is defintely NOT vague. With the provided dataset, with the provided configurations, on Windows, QGIS crashes when clicking on "run" in the geometry checker tool. I can't see how this is vague.

This does NOT happens on Linux (not on clicking "run" anyway). There it happens after clicking on the (new) errors rows after a first run to clean an auto-intersection. That row by the way, are empty here on KDE.

A screencast is ok to clear this "vagueness"?

#22 Updated by Sandro Mani about 3 years ago

I was referring to the issue Bogdan Hlevca is experiencing which is a crash when starting qgis. In his case, since no actual steps were performed in QGIS itself as I understand, for a developer there is no way to know what's going on without a stacktrace.

In your case, you reported pretty detailed steps how to reproduce and as far as Linux was concerned it was pretty straight forward to debug. Windows which cannot be reproduced on Linux are more annoying because I need access to a windows + visual studio machine and then build qgis there before even being able to start debugging... That said, if you can provide a stracktrace of the windows crash I'd clearly be happy, especially if it spares me the effort of the windows build ;)

Because I cannot compile I can run only the binaries provided by OpenSuse, which do not have enough debug info. See below. I thought that ltrace may have helped you a bit. I still think it is sip related as is the only dependency that got changed at the latest upgrade. I will try you patch and see if I can compile

#24 Updated by Bogdan Hlevca about 3 years ago

I compiled fine with your patch but the crash is still there. Here is a backtrace

(gdb) backtrace

I hope that it helps because I am really depending on the tools and I don't have a single version that works on my machine and changing the whole library environment is not a viable option.

#25 Updated by Bogdan Hlevca about 3 years ago

now that I look again at the backtrace I noticed that The app uses both libqwt 5 and 6. This is wrong

#26 Updated by Bogdan Hlevca about 3 years ago

Does not crash anymore. I deleted libqwt6 and I recompiled qwtpolar with qwt5. Recompiled everything from scratch.

To recapitulate:
  1. Needs your sip patch to compile
  2. very sensitive to qwt libraries. People must check if 2 different versions are on the path

I hope that this helps other to find their own problems with 2.18 and sip 4.28 and various qwt libraries

#27 Updated by Giovanni Manghi about 3 years ago

  • Status changed from Reopened to Closed
  • Resolution set to fixed/implemented

Retested on the same platform on 2.18.4 and it worked as expected. Thanks!
