Problem with print with json-styled strings
zachup100 opened this issue · 2 comments
I am running into an issue where I cannot debug the results of a SQL query. The output contains a JSON string. Oddly, only when the function allows the passthrough of the second argument, this issue occurs. If I were to remove the second argument, 'out', prints work as intended. The string in question is shown below. The variable READ_SQL is from the Luvit-MySQL github linked below.

{"Party": {"Lobby": "0", "Category": "0", "Template": "{USERNAME}'s Party"}, "Prefix": "!"}
function GetGuildInfo(Id)
local Guild = Guilds[Id]
local Finished = false
if not Guild then --// load if not in memory
READ_SQL:query(string.format("SELECT Config FROM Guilds WHERE Id='%s'", Id), function(err, out)
if out then
Guilds[Id] = {}
Guilds[Id].Info = json.parse(out[1].Config)
Guilds[Id].LastPing = os.time()
Guild = Guilds[Id]
Finished = true
end
if type(err) == "table" then print("Unable to select config for GetGuildInfo() => ("..err.number..") "..err.message) end
Finished = true
end)
end
print(Finished)
return Guild.Info
end
GetGuildInfo("612506098779553793")Edit: Forgot the error code

Seems like uv.fileno is returning nil here:
Line 302 in f31d243
Not sure why that would be, or how the out parameter could possibly have an effect. From the fileno docs:
Gets the platform dependent file descriptor equivalent.
The following handles are supported: TCP, pipes, TTY, UDP and poll. Passing any other handle type will fail with EINVAL.
If a handle doesn't have an attached file descriptor yet or the handle itself has been closed, this function will return EBADF.
Well, messing around with the arguments, the only time I can't access print is when I define the second argument in the function. As well as I think it might be failing to finish the function as 'Finished' variable doesn't change. I even tried replacing the apostrophe with a replacement string such as {APOS} to see if it's an escape problem. But the problem still occurs afterwards.
The platform I am using while debugging and testing on is Windows 10 20H2 OS Build 19042.685
