Incorrect File Size Calculation During Upload for Compressed Files in Birth Registration

[nifaliana]

Describe the bug
During the birth registration process (tested in OpenCRVS-Madagascar), files are compressed before being uploaded. However, the system calculates the total upload size based on the original, uncompressed file sizes, which results in an incorrect size calculation for enforcing the 20MB limit.

I should be able to upload multiple compressed files as long as their total size remains under the 20MB limit. However, the system currently restricts me to only three files because it incorrectly calculates the total size based on the original file sizes rather than the compressed sizes.

Which feature of OpenCRVS your bug concerns?

This bug concerns the File Upload feature during birth registration. Specifically, it involves the compression process and the enforcement of the 20MB file size limit.

To Reproduce
Steps to reproduce the behavior:

• Log in as a system admin or registrar.
• Go to the birth registration form where files can be uploaded.
• Upload multiple files.
• Compression will occur during the upload process.
• The total file size is calculated based on the original files instead of the compressed versions.
• See error where the upload may be allowed or rejected inaccurately due to the wrong size calculation.

Expected behavior
The total size of the uploaded files should be calculated based on the compressed versions of the files. The system should ensure that the total size of the compressed files does not exceed the 20MB limit, preventing any inaccurate size limit enforcement.

Actual behavior
Currently, the system calculates the total size based on the original file sizes before compression. This causes the size limit enforcement to be incorrect, potentially blocking uploads even when the compressed total is below 20MB.

Screenshots

OpenCRVS Core Version:
v1.6.0 (Git branch: master / release-v1.6.0)

Country Configuration Version:
v1.6.0 (Git branch: master / release-v1.6.0)

Desktop (please complete the following information):
OS: Ubuntu 24
Browser: Chrome
Version: recent version 130.0.6723.58

Possible fixes
Modify the file size calculation logic to only include the sizes of the compressed files instead of the original file sizes.
This can be done post-compression during the upload process.

Reproducible demo
N/A (If available, provide a demo link or project for reproduction.)

Hi Rija, thanks for reporting!

During the birth registration process (tested in OpenCRVS-Madagascar), files are compressed before being uploaded. However, the system calculates the total upload size based on the original, uncompressed file sizes, which results in an incorrect size calculation for enforcing the 20MB limit. I should be able to upload multiple compressed files as long as their total size remains under the 20MB limit. However, the system currently restricts me to only three files because it incorrectly calculates the total size based on the original file sizes rather than the compressed sizes.

I think what causes confusion and the weird experience is the fact that we allow countries to define compressImagesToSizeMB to which all files are compressed to but the total maximum file size is controlled by maxSizeMB, calculated from the original file sizes.

The way to solve the issue is either

• Allow countries define compressImagesToSizeMB and maximumNumberOfFiles. This would allow you to understand the required disk space for each file upload by calculating compressImagesToSizeMB * maximumNumberOfFiles. Users could then be only restricted from uploading more than maximumNumberOfFiles files. This approach is problematic as in the future we want to upload PDFs for instance which we cannot reliably compress.
• Define maximum total size for original files. Inform user if this limit is exceeded. In this approach we can compress the files the best we can after the user is finished uploading, but the user is not affected by the outcome. User can understand how many files they can upload based on the file sizes in their file system.

@jpye-finch @Alta-Nel what are your views on this? Think we need to consider the most user-friendly option here.

Hello @rikukissa,

By the way, can country integrators customize the maxSizeMB value ?
I saw a kind of default value of 20MB in the code.

Total file size calculation fixed in #7961
Solution tested by Madagascar team. Merged to 1.6.1 and will be released by it.

Thanks @rikukissa and @tahmidrahman-dsi 🙏 .
Could you let us know the tag once it has been deployed ?
