@test_logs when using @threads

[orenbenkiki]

Currently, when using @threads in code tested by @test_logs, the log entries emitted by threads with threadid() > 1 are not captured.

It is possible to work around this by writing:

logger = current_logger()
@threads for ...
    with_logger(logger) do
        ...
   end
end

It seems as though each thread inherits the global logger that was in use at the launch of julia, instead of the logger that was in effect at the time the @threads loop was invoked. Should the default behavior of @threads be modified to the above workaround instead?

Thanks for the report.

Presumably once #22631 is merged everything related to threading will change. I hope at that stage I'll have time to "take concurrency seriously" as regards to logging :-)

All I/O is currently non-thread-safe; #29706 should fix that.

#22631 and #29706 were both closed in March...
