[digiKam-users] --> Digikam 6.3 unstable and DEBUG

[Alex Antão]

Hi,

 

    I'm running digikam om MacOSx High Sierra.

    This 800Gb are a mix of Photos and videos. I have Photos in JPEG, PNG, HEIC and NEF formats.



    This library was exported fom Mac Photos 3.0 and are all located in an external HD formated to HFS+.



    Digikam ofter crashes on several parts, when I ask to recognize faces, to update Fingerprints (noticed that in a subset of the library this is more dificult to happen).

    For example, the last time it crashes, I had selected a few photos, clicked on Tools tab, selected Tag Manager, it opened a window with all Tags, and when I closed it, it crashed. 



    I really want to migrate to Digikam, because my Photos App is not reliable anymore (discovered I have 720 photos missing on it, but it does not know, only when I try to export them), but I need Digikam to be stable enough to try to fullfill all my needs...



    I'm runing it with AppImage, I don't have time to DEBUG it, but seeing the logs are suficiente to try to discover a possible problem and ask for help.


Thanks....

Hi,





 I just downloaded the last version of Digikam.

 My library is huge, about 800Gb with more than 100.000 photos, and I am still organizing it, from a export of Photos Library to a External HD.






Hi,



This is a very huge collection. I never tested in this kind of configuration. Yere my collection is about 200000 JPEG files but size is around 300 Gb on a SSD drive.



Which kind of database do you use exactly ? where is stored this database ?

 





 I don't know when exactly, but I'm felling digikam quite unstable. It crashes often. I am reorganizing the Library with some scripts I'm developing.

 For example, I just opened it and it started scanning the changes I've done on the files, but when I click on my root Album, it crashes. But it does not if I left it untouched



 I ordered it to generate Fingerprints and it crashes. But it does not if I select only one album to generate.



I tried to open it from terminal to see if there are some error messages, but none was printed.






It's abnormal. Your linux system hide Qt debug spaces with a default configuration. I already fixed this rule to under Centos. It just a text file to change on the system. Which Linux system do you use exactly ?

 

Before to run digiKam set this env. variable :



export QT_LOGGING_RULES="*.debug=true"








Is there a way to debug and see what's going on?








Yes, sure. With AppImage bundle, start digiKam with debug argument. It will run digiKam in GDB.



If you don't use AppImage, just start digiKam in debugger as explained here :
