Package: lua-socket
Version: 3.0~rc1+git+321c0c9-1
Severity: normal
Dear Maintainer,
I'm trying to use socket.http from mpv. My script looks like this:
$ cat test.lua
local http = require("socket.http")
local url = "http://rohieb.name";
print ("MARK")
d,c,h = http.request(url)
print (("HTTP %d"):format(c))
... and works fine with the Lua 5.2 interpreter:
$ lua5.2 test.lua
MARK
HTTP 200
However, when I use it with mpv, it segfaults on the http.request() line in
timeout_markstart(), see the attached GDB session transcript. A simple fix would
be to test for tm==0 in timeout_markstart(), but I'm not sure what is going on
here and why tm is 0 to begin with.
Cheers,
- Roland
