Bug ID: 397207
Summary: Too many open files, when reverse geocoding many
images
Product: digikam
Version: unspecified
Platform: Other
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: Geolocation-ReverseGeoCoding
Assignee: digikam-bugs-n...@kde.org
Reporter: kristian.hermann.k...@gmail.com
Target Milestone: ---
Created attachment 114319

Proposed patch
Running reverse geocoding on a large set of images, generates error:
GLib-ERROR **: Creating pipes for GWakeup: Too many open files
Actions
=======
1) In the Geolocation Editor, select the Reverse Geocoding tab.
2) Select a large set of images. I used 5,000 images.
3) Select Open Street Map as the service
4) Click on Apply reverse geocding button
Expected result
===============
All images with coordinates are reversed geocoded.
Actual result
=============
After around 1,0000 requests, digikam crashes.
First I got a SSL Handshake failed, error message dialog.
Then when I exit the Editor, digikam crashes with:
GLib-ERROR **: Creating pipes for GWakeup: Too many open files
Additional info
===============
Running the same scenario again, and tracking number of open files using:
watch -n1 "ls -la /proc/$(pidof digikam)/fd | wc -l"
I could see that the number was increasing, until I ran into the same problem.
A similar issue (https://github.com/albertlauncher/albert/issues/634) was fixed
by
https://github.com/albertlauncher/albert/commit/70e3662a8e3a08137073b5932dbd7ddee136ff65
When I tested their approach on digikam, digigam did not crash running the same
scenario.
Given the above I propose the attached fix.
