…JuliaLang#57004) Fixes JuliaLang#56889. Before this PR, an exception thrown while constructing the objects to log (the `msg`) would be caught and logged. However, an exception thrown while _printing_ the msg to an IO would _not_ be caught, and can abort the program. This breaks the promise that enabling verbose debug logging shouldn't introduce new crashes. After this PR, an exception thrown during handle_message is caught and logged, just like an exception during `msg` construction: ```julia julia> struct Foo end julia> Base.show(::IO, ::Foo) = error("oh no") julia> begin # Unexpectedly, the execption thrown while printing `Foo()` escapes @info Foo() # So we never reach this line! :'( println("~~~~~ ALL DONE ~~~~~~~~") end ┌ Error: Exception while generating log record in module Main at REPL[10]:3 │ exception = │ oh no │ Stacktrace: │ [1] error(s::String) │ @ Base ./error.jl:44 │ [2] show(::IOBuffer, ::Foo) │ @ Main ./REPL[9]:1 ... │ [30] repl_main │ @ ./client.jl:593 [inlined] │ [31] _start() │ @ Base ./client.jl:568 └ @ Main REPL[10]:3 ~~~~~ ALL DONE ~~~~~~~~ ``` This PR respects the change made in JuliaLang#36600 to keep the codegen as small as possible, by putting the new try/catch into a no-inlined function, so that we don't have to introduce a new try/catch in the macro-generated code body. --------- Co-authored-by: Jameson Nash <[email protected]>
