8 months ago Here a MWE run julia docker with
docker run -it --rm julia:1.9 bashand start julia. Then run the following code and while the last sleep is running, hit CTRL-c to interrupt the julia session
import Pkg
Pkg.add(["HTTP", "PythonCall", "Sockets"])
using HTTP
using PythonCall
import Sockets
function default_404(req = nothing)
HTTP.Response(404, "Not found!")
end
router = HTTP.Router(default_404)
@warn "pid = ..."
os = pyimport("os")
pid = os.getpid()
@warn "pid = $pid"
function get_pid(request::HTTP.Request)
@warn "pid = ..."
os = pyimport("os")
pid = os.getpid()
@warn "pid = $pid"
return HTTP.Response(200, string(pid))
end
HTTP.register!(router, "GET", "/pid", get_pid)
port = UInt16(32132)
serversocket = Sockets.listen(port)
server = HTTP.listen!(port; stream=true, server=serversocket, verbose=-1) do http::HTTP.Stream
request::HTTP.Request = http.message
request.body = read(http)
response_body = router(request)
@show response_body
request.response::HTTP.Response = response_body
request.response.request = request
try
HTTP.setheader(http, "Content-Length" => string(length(request.response.body)))
# https://github.com/fonsp/Pluto.jl/pull/722
HTTP.setheader(http, "Referrer-Policy" => "same-origin")
# https://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#:~:text=is%202%20minutes.-,14.38%20Server
HTTP.startwrite(http)
write(http, request.response.body)
catch e
if isa(e, Base.IOError) || isa(e, ArgumentError)
# @warn "Attempted to write to a closed stream at $(request.target)"
@debug "that is fine error" exception=(e, catch_backtrace())
else
rethrow(e)
end
end
end
sleep(2)
HTTP.get("http://localhost:$port/pid")
sleep(100)It gives the following error
julia> sleep(10)

Affects: PythonCall
Describe the bug I just turned off threads to make PythonCall work, but now I experience that every time I try interrupting the julia REPL (with PythonCall loaded and used inside a WebServer) it results in a fatal error which crashes the whole Julia REPL (however I would like to stay in the julia REPL)
Here the error message
I was not able to simplify it to a MWE yet. Maybe the above error is already somehow self-explaining.
