fix(BaseTransport) Fix handling of AbortSignal availability detection in selected transport #1582
Conversation
Updated the assignment of the signaller variable in the BaseTransport class to ensure proper usage of AbortSignal.timeout. The debug message for when AbortSignal.timeout is not defined has also been adjusted for clarity.

Hello @p3drosola, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!
Summary of Changes
This pull request addresses an issue in the BaseTransport class related to the handling of AbortSignal and its timeout property. Specifically, it corrects the assignment of the signaller variable when AbortSignal.timeout is available and ensures that the debug message for when AbortSignal.timeout is not defined is displayed at the appropriate time.
Highlights
- Bug fix: Corrects the assignment of the
signallervariable whenAbortSignal.timeoutis available. - Improvement: Ensures the debug message for the absence of
AbortSignal.timeoutis displayed at the correct time.
Changelog
- packages/sdk-rtl/src/baseTransport.ts
- Corrected the assignment of the
signallervariable to use the result ofAbortSignal.timeout(ms). - Moved the debug message for when
AbortSignal.timeoutis not defined to the correct conditional branch.
- Corrected the assignment of the

Code Review
The pull request addresses an issue with the handling of AbortSignal.timeout in the BaseTransport class. The changes ensure that the signaller variable is properly assigned and that the debug message for when AbortSignal.timeout is not defined is executed at the correct time. Overall, the changes seem reasonable and address the described issue.
Summary of Findings
- Variable reassignment: The reassignment of the
signallervariable within theif (AbortSignal.timeout)block fixes a potential scoping issue where the timeout signal was not being correctly applied. - Debug message placement: Moving the debug message outside the
if (AbortSignal.timeout)block ensures that it is only displayed whenAbortSignal.timeoutis actually undefined, improving the clarity of debugging information.
Merge Readiness
The pull request appears to address the described issue effectively. The changes are relatively small and focused. I recommend merging this pull request after addressing the review comments. I am unable to directly approve the pull request, and users should have others review and approve this code before merging.

This log was being generated even if AbortSignal.timeout was available in the runtime, since it was attached to the wrong condition (options.signal)

Removed double let declaration, since it's block scoped, and would cause a new blocked scoped variable, which shadowed the top level signaller but the blocked scoped value was never included in props, since it's destroyed as soon as this block is executed.
Updated the assignment of the signaller variable in the BaseTransport class to ensure proper usage of AbortSignal.timeout. The debug message for when AbortSignal.timeout is not defined has also been made to execute at the correct time.
