Unable to build pendulum for 32bit

[hesstobi]

• [ x] I am on the latest Pendulum version.
• [x ] I have searched the issues of this repo and believe that this is not a duplicate.

• OS version and name: Linux 32bit
• Pendulum version: 3.0.0

Issue

Trying to build pendulum for a 32bit system fails:

-> src/helpers.rs:59:20
         |
      59 |         seconds += ((146_097 - 10957) * SECS_PER_DAY as usize) as isize;
         |                    ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ attempt to compute `135140_usize * 86400_usize`, which would overflow
         |
         = note: `#[deny(arithmetic_overflow)]` on by default

usize is only a 32 uint on 32 bit systems, thus this is not working.

[Secrus]

Unless you are up to making the change required for this to work on 32 bit system, I doubt it will change.

[hesstobi]

This was my concern.

As far I understand it would work, if the seconds variable in is changed to i64.

I can try to start with rust programming and prepare a PR for that.

Is there a way to force the install to fall back to the pure python implementation?

EDIT: Or could a pure python wheel be published to pypi to fall back on?

@gazpachoking maybe the PENDULUM_EXTENSIONS=0 env var?

[gazpachoking]

I tried that env var. It seems that only disables the extensions at run time. I don't see a way to install without building the rust extensions at all.

We added pendulum as a dependency in our project and are now having multiple reports of people who can't install on their platform because either it's 32 bit, or they don't have rust tooling and there isn't a prebuilt wheel for their platform. I really hope official way is added such that pendulum can fall back to the pure python implementation in those cases.

Other than 32-bit, could you maybe come up with a list of platforms we don't cover?

[gazpachoking]

I'll try to collect some data from our users with troubles. It's possible it's just 32bit users on raspberry pi like systems.

Looks like linux aarch64 at least. (If that's not the detail needed there is more here)
EDIT: Hmm, I may not have read that log closely enough. That might be a different issue.

[JakFrost]

Same problem as original poster when running on Ubuntu 18.04.6 LTS and 32-bit.

Cannot update Pendulum package since it required Rust and Cargo so installed those packages rustc and cargo just fine. Then it gets the same error as above.

I also noticed that the line PYO3_ENVIRONMENT_SIGNATURE="cpython-3.8-64bit" is set to 64-bit instead of 32-bit.

I'm not sure why all of a sudden a new language is required to be installed for this package dependency and it is now failing for 32-bit systems since it appears that the build for Rust -> Cargo -> Maturin makes the hardcoded assumption that the system is always 64-bit.
