nixio's Issues

build failures with openssl 3.0

Hi. Just noticed that nixio fails to build with openssl 3.0 due to deprecated functions.

new rockspec version 0.3.2 and into luarocks repo?

nixio doesn't build anymore with gcc 4.8.0+ on luarocks's version 0.3.1

A commit was made to fix this in scm over here:
07f91ad

However, in the default luarocks build server, the rockspec is still 0.3.1 with an older version of the source.

It would be great to issue a new version so that nixio build by default in luarocks without having to manually pull the scm rockspec

luarocks install nixio fails

on a fresh ubuntu 1204 machine, "sudo luarocks install nixio" doesn't work properly. It installs a broken nixio that doesn't have the fix for 7220cef

I don't know where luarocks is fetching it from exactly?

How can I help?

nixio.bit.check is meant to accept multiple flags but doesn't

At least on the documentation at http://luci.subsignal.org/api/nixio/modules/nixio.bit.html#check the check function is meant to check all flag arguments. On both my local fedora installation via luarocks, and my openwrt installation, this is clearly not happening:

root@OpenWrt:~# lua
Lua 5.1.4  Copyright (C) 1994-2008 Lua.org, PUC-Rio (double int32)
> nix = require("nixio")
> x = 6
> =nix.bit.check(x, 2)
true
> =nix.bit.check(x,3)
false
> =nix.bit.check(x,2,3)
true
> =nix.bit.check(x,3,2)
false
> 

Only the first flag is checked. This matches up with the source at https://github.com/Neopallium/nixio/blob/master/src/bit.c#L103 which is clearly only checking the first argument.

Now, this clearly works as implemented, but the docs are not right at least.

hi, can nixio socket object been passed to another thread?

hi neo,

I am using lua-handlers to write a http server. Now I want to process static files in other threads, so after parse the http request, I need to pass the file uri and nixio socket object to other threads (I use lua-llthreads), other threads use nixion.sendfile to server files, so they must get the socket object to response correctly. How should I do to pass socket object?

Expect your reply.
Thank you.

lstat patch (fs.c)

Patch replace stat to lstat.

Reading from standard input?

I have an applications that uses sockets to distribute data read from the standard input. I don't see how I can get a file descriptor for standard files for nixio. (the ones from Lua like io.input() do not work)

A method for geting clock time is wanted

There seems to be no way of getting clock time (i think).

Adding the dereference makes it it compile, but it is correct?
