Re: Running a code block with timeout

Hi Aziz, Thank you for your suggestion. We will use it in an API, so good error reporting is a concern for us. We thought about executing the evaluation in a subprocess and use the exit code to report errors. However, this approach has some performance penalties as it requires serializing the input context data and deserializing the result. - Marcos Em qua, 30 de out de 2019 às 09:15, Aziz Saleh <azizsaleh@gmail.com> escreveu: > > On Wed, Oct 30, 2019 at 8:03 AM Marcos Passos <marcospassos.com@gmail.com> > wrote: > >> Hi everyone, >> >> We're looking for a way to run a code block with a timeout. >> >> Our use case involves evaluating an expression written in a custom DSL >> (similar to Symfony Expression Language), and we want to ensure that the >> execution will not exceed a given time limit. >> >> We tried a naive approach using set_time_limit, but there is no way to >> catch the exception from the block code that timed out.
