scs library client (singularity 3.6.x) requires all lowercase to push

[atharvnagarikar]

Hi, I followed all your guidelines and setup GUI for the singularity registry server and I also verify the token and all but while trying to push the image to the collection I encountered the following fatal error

Following image will show you the GUI along with the collection

Can you please help me with this

That looks correct - what version of Singularity are you using? sregistry is tested up to 3.5.x. The error message I see seems to be coming from Singularity so something is changed or erroneous there.

[atharvnagarikar]

I'm using Singularity 3.6.4 version

[vsoch]

Could you please try 3.5.2 or 3.5.1? That will rule out a version upgrade issue.

[vsoch]

It looks like they've added a new check that checks against this regular expression: https://github.com/sylabs/scs-library-client/blob/31250b63795e4a20afd8f4f00b2ad3b34ec188e0/client/util.go#L28. So my thinking is that the issue is that you have a capital letter. Could you try an all lowercase name, no special characters, and if that works I can do an update to sregistry to enforce it as well?

[vsoch]

Yeah, try changing your username to all lowercase, e.g., see how it matches after we do that:

# Doesn't match regex and fails check as is now
re.search("^(library://)?([a-z0-9]+(?:[._-][a-z0-9]+)*/){2}([a-z0-9]+(?:[._-][a-z0-9]+)*)(:[a-z0-9]+(?:[,._-][a-z0-9]+)*)?$", "library://Singularity_CDAC_LSM/ai/test:latest")
# no match is returned

# passes
re.search("^(library://)?([a-z0-9]+(?:[._-][a-z0-9]+)*/){2}([a-z0-9]+(?:[._-][a-z0-9]+)*)(:[a-z0-9]+(?:[,._-][a-z0-9]+)*)?$", "library://singularity_cdac_ssm/ai/test:latest")
<re.Match object; span=(0, 45), match='library://singularity_cdac_ssm/ai/test:latest'>

[atharvnagarikar]

ok, I'll try and let you know

[vsoch]

If the lowercase works, here is a PR for you to test that should create the same username, all lowercase. #332 I have to be off to bed, looking forward to hearing how it goes!

[atharvnagarikar]

lowercase work and now I can push the image to loaclhost

[vsoch]

Great! Could you test the pull request and confirm that when you login with your username the username with capital letters is already all lowercase? If we merge this pull request then the issue will be fixed for future users. Thanks for your help!

[atharvnagarikar]

For pulling an image, should I use singularity registry client

[vsoch]

No, you should use singularity with the library endpoint.

[atharvnagarikar]

ok

[atharvnagarikar]

I pulled the image successfully

[vsoch]

Have you tested the PR?

[vsoch]

@atharvnagarikar thank you for opening this issue - and I'm glad we have resolved it. You should consider in the future that open source is a two way street - I help you here, and when I create a solution for you, it is good practice to test it to confirm that it fixes your issue. If you want to have good relationships with maintainers, not just here but anywhere on GitHub, you should try to be more helpful.

[atharvnagarikar]

@vsoch, thank you for your guidance and I was not able to come online due to some personal issues

[atharvnagarikar]

Can you please elaborate #332
