Memory shortage when searching on Linux

[daigriffiths]

Describe the bug :


I get a message from the kernal saying:


Memory Shortage Avoided
The background service app-\x2fhome\x2fdai\x2fQualcoder\x2fQualCoder_3_8_2_ubuntu@bbcc7315e79d42fe9efdbd058e2018ef.service has been terminated by the Linux kernel because the system is low on memory. Consider closing unused applications or browser tabs.

To Reproduce :
When I search for a text in a document which I am coding, the search function works fine. When I delete the search string letter by letter the number shown in the hits counter increases. When I am down to one or two letters, Qualcoder crashes and I get a "Memory Shortage Avoided" message. If I select the whole search string and delete it, Qualcoder again crashes. Sometimes the whole computer crashes, and I need to restart.

Expected behavior :


I expected to be able to delete the search string letter by letter, and to then type in a new search string.

Screenshots :


If applicable, add screenshots that helps to explain your problem.

Thanks for a great application!

Hi. I fixed an error in previous releases. Fixed in the current 4.0 code relating to this. It might fix the memory error. This is because in a very large document a list of the matches is created, and this could become a very large size.

I'm glad you like the application

Thanks for replying, this sounds like it might do the trick.
I don't understand what you mean by "...this was ignored - the error". Is it not to be included in 4.0?

Would rolling back to an earlier version help? I am not sure how much backwards compatability there is for my existing projects.

Sorry for the misunderstanding - the fix is in the "4.0 in development" version.
I checked an older version 3.6, and the flaw was still there.
I recommend that you use the 4.0 version that you can download from the green button on this page: https://github.com/ccbogel/QualCoder

As always, save a copy of your project folder first.

Unzip the zip folder in Downloads (for example). In the Qualcoder-master folder make the run_from_source_Ubuntu.sh executable:

I don't know how familiar you are with the Terminal so I've added the following:
Open the terminal - usually ctrl shift N does this (I have Lubuntu 24.04).
Then use the "cd" command to move to the Qualcoder-master folder, and run the shell script using the following command:

./run_from_source_Ubuntu.sh

The very first time it will be slower opening as it is creating a virtual python environment and filling it with everything needed. On subsequent uses from the terminal it will be much faster as the environment is present.

Later this year we will also do an exe once we have organised a few additions that we want to implement.
