feat(sdks): expose init exit code on box info - #1237
Conversation
The core records the init's exit code when a box stops because its command exited, but every SDK binding dropped the field on the way out, leaving callers with no way to read a completed workload's status. Node and Python surface it as a nullable field. C pairs `exit_code` with a `has_exit_code` flag because 0 is a valid exit code and cannot double as "none recorded" the way `pid` does; Go maps that pair to a `*int`.

- Line 247: Update the BoxStateInfo `state` field description to specify that
`exit_code` contains the init command’s exit code only when the box stopped
because that command exited; retain the existing nullable-field and
runtime-state details.
In `@sdks/c/src/info.rs`:
- Around line 259-260: Add a public Rust doc comment immediately before
CBoxInfo::from_box_info documenting that None maps to exit_code 0 with
has_exit_code 0, Some(0) maps to exit_code 0 with has_exit_code 1, and nonzero
values preserve the exit code with has_exit_code 1.

JsBoxInfo::from, and assert the resolved state preserves Some(0) alongside the

Document on `CBoxInfo::from_box_info` how `None` and `Some(0)` differ in the `exit_code` / `has_exit_code` pair, and cover that mapping directly. The Node and Python conversions now assert `Some(0)` survives, since collapsing it to `None` would report a successful workload as one that never ran, and the Python case asserts `__repr__` carries the field users print.

I'm not very familiar with your code base. I used Claude to help me with this. Unfortunately this is a blocker for me. Anything else I can work through or help with I am willing to do. Thank you! |
Brings the branch onto 118 commits of upstream history, most notably the `CNetworkInfo` outbound/inbound split (boxlite-ai#1206), which collided with the init exit-code work in the C SDK's `info.rs`. The one conflict was in that file's `#[cfg(test)]` module, where both sides rewrote the `use super::{…}` list and appended tests. Resolved by keeping both: the module now imports `CBoxInfo`/`free_box_info` and `CNetworkInfo`, and carries the exit-code mapping test next to the network-direction ABI tests. `CBoxInfo`'s new `exit_code`/`has_exit_code` pair sits after upstream's reworded `started_at`, matching the header.

Note GitHub couldn't provide a complete incremental comparison for this pull request, so CodeRabbit is performing a full review instead. This review may take a little longer. |
