Install failure on CI

[quinnhornblow]

• whitebox version:
• Python version: 3.11.6
• Operating System: Linux

Description

I am trying to test a function that uses whitebox with pytest. Tests pass locally but when I run the tests on a CI pipeline (bitbucket) they fail. It appears to be an error with the download and setup. I have tried with different combinations of musl and reset but all fail. CI pipeline is run on linux.

whitebox.download_wbt(
    linux_musl=False,
    reset=False,
    verbose=True,
)

What I Did

See below for snip from CI output.

Yes, this is a known issue. Downloaing WBT binaries automatically from whiteboxgeo.com sometimes gets a timeout error. That's whey I placed some backup links in download_wbt just to pass the CI tests.

whitebox-python/whitebox/download_wbt.py

Line 58 in 117f08e

backup_links = {

It's not a timeout error though... it happens here when unzipping the download.

I see that line 108 checks if zip_ext == ".zip": # Decompress Windows/Mac OS zip - but all of the links and backup links are .zip?

Also line 87 sets the zip_name from the url, then the url is potentially updated in line 99. I'm not sure what impact this has (if any) but why not set the zip_name after line 101?

[giswqs]

It works fine on Colab. The issue is probably caused by the corrupted file downloaded from whiteboxgeo.com when the download is not complete. It is not a valid zip file, so it throws errors when trying to unzip it.

[quinnhornblow]

Ok, so it sounds like you are aware of the issue and know what's causing it. It's not clear what your proposed solution is though. Since it's a timeout issue, does the timeout parameter in the urllib request need to be increased? or do I need to change something with my CI pipeline?

[giswqs]

The timeout vlaue is already set to 500 seconds, which should be long enough. The issue is probably because whiteboxgeo.com rejects automated download request from time to time. I don't know why.

Here is a previous discussion on this issue: giswqs/whitebox-bin#1

I don't have a solution to this. Suggestions are welcome.
