[wxlua-users] wxURL locking on GetInputStream()

[Daniel A. <mr....@gm...>]

I'm having lockups when I try to pull an http page using wxURL.

It gets stuck at GetInputStream but then appears to work fine after
right clicking on the systray icon...

I believe it may be the threads issues that are described on this page:

http://wiki.wxwidgets.org/WxURL

quote: "Under Windows, wxURL and wxThread may have problems to work
well together. Be sure to construct the wxURL and call
wxURL::GetInputStream inside the main thread."



function get_games()
	local url = wx.wxURL("http://fly.thruhere.net/status/games.json")
	local stream = url:GetInputStream()
-- freezes here
-- frees up if you right click on the systray icon
	local size = stream:GetSize()
	local data = stream:Read(size)
	return data
end

I assume you are under MS Windows? XP?

wxLua always runs everything in the main thread unless you have
created another thread.

I don't get any delays running your code in MS Windows XP using
wxlua.exe, wxluafreeze.exe, and wxluaedit.exe. They all get a size of
4 and the stream is:

"{
}
"

which version are you running ?

I could only find binaries for 2.8.7 but wxlua is up to 2.8.10...

It still happens even when I comment out all other code...

I use 2.8.10.

You can download them here, note that 2.8.10 is in the middle since it
sorts by name and not by when it was uploaded, apparently.

http://sourceforge.net/projects/wxlua/files/

Weird, but definitely try the 2.8.10 since I remember some posts to
the wxWidgets development list about changes to the socket code a
while back and so your problem may be fixed.
