keep not working

[IgnacioHeredia]

Unless I'm missing something very obvious, I don't think --keep is working as expected.

Reproduce:

1. download record
2. modify file
3. download record with --keep

The file seems to be redownloaded again, ignoring keep and overwriting my changes. I would expect that the second time nothing is downloaded.

-k : keep files: it will keep files with invalid md5 checksum. The main purpose is debugging.

Version 1.6.1.

Thanks!

My understanding of the --keep option is :

Without --keep (normal behaviour)

1. download a file from zenodo
2. check md5
3. if md5 mismatch delete the downloaded file (do not KEEP it)

With --keep

1. download a file from zenodo
2. check md5
3. if md5 mismatch KEEP the downloaded file

What you do is modifying the LOCAL file, hence zenodo_get sees it is not conform to zenodo anymore at step 1, so it downloads it and proceeds with the other steps.

the keep option has nothing to do with KEEPING the already downloaded files when they have been modified...

@serasset That's the correct interpretation, I meant it as "if there is a checksum mismatch, then whether or not keeping the "damaged/mismatched" file.

@IgnacioHeredia So you want to avoid downloading files which are already downloaded?
I will look into it, but honestly, I wrote this piece during my phd in a weekend out of annoyance, that reflect code quality and design too, so every time I need to recall the details. I am quite busy, but I will see what I can do.

No worries @dvolgyes , it's not a pressing issue. Thanks for the tool!
