Load Session from Zipfile

[kojiromike]

When attempting to use botocore / boto3 in AWS EMR or PySpark, it's necessary to load from a zipfile. However, botocore does not support this.

+ PYTHONPATH=botocore.zip:boto3.zip
+ .venv/bin/python -c 'import boto3; client=boto3.client("rds")'

Hello! I'll try to make sure this continues to get attention until someone engages in a real conversation about it. This is September 2021. The original PR was from Feb 8, 2020.

[kojiromike]

Hi, friends, it's now October 2021. Trick or treat, please merge this PR 👻 🍫 🍬 !

[alete89]

Can't wait for this!

[kojiromike]

Hello, it's January 2022. Maybe someone can look at this this year?

[kojiromike]

Hello, February! I hope the events of this month turn out to be less harmful than they seem right now 🇺🇦.

I also hope that maybe this PR will not be forgotten.

[gliptak]

boto3/botocore might also benefit from https://github.com/aws/aws-cli/pull/6828

[kojiromike]

Hi, it's May. May I merge this some day?

[kojiromike]

Hi, we continue to occasionally have engineers run into this problem. It's a chore to have to remember to explicitly exclude boto3 from our EMR job zipfiles to avoid what appears to us to be a completely unnecessary problem.

[kojiromike]

Hello from April, 2023, I hope you've been having a great year so far. Any chance someone from AWS could address this?

[kojiromike]

Hello from June, 2023. It'd be great if AWS could take a look at this.

[kojiromike]

Hello from April 18, 2024! How's everyone doing this year? Well enough to look at this PR, maybe? :D
