Apache Arrow JIRA Bot reassigned ARROW-13370:
---------------------------------------------
Assignee: (was: Dragoș Moldovan-Grünfeld)
> [R] More special handling for known errors in arrow_eval
> --------------------------------------------------------
>
> Key: ARROW-13370
> URL: https://issues.apache.org/jira/browse/ARROW-13370
> Project: Apache Arrow
> Issue Type: New Feature
> Components: R
> Reporter: Neal Richardson
> Priority: Major
>
> *Proposed approach*:
> * Investigate the use of {{rlang::abort()}} with the class arg
> * Investigate if an expansion of the {{arrow}} error classes is required
> * Surface error messages that do not contain the "not supported in Arrow"
> keywords
> * Update unit tests
> * Document updates in error-handling
> *Original description*:
> We have special handling in arrow_eval that looks for the "not supported in
> Arrow" error, and when that's found it shows the error message rather than
> swallowing it in an "Expression not supported" message. But we have other
> error messages we raise in nse_funcs that are worth showing--bad input etc.
> Use a sentinel error message that we can also detect and subclass as
> "arrow-try-error" like the others, or (better) raise a classed exception (if
> that's supported in all versions of R we support).
