Vera - Show Lua Module Versions

Developer's Corner
1

Hi

I came across a piece of code thats scans all my Lua files to see if any have a version reference recorded anywhere. I did this because I was interested to know the version of some of the key Lua modules, especially luasec/https

See code and findings below.

local command = io.popen("find . -type f -name '*.lua' | xargs grep -H 'VERSION *=[^=]'")
local response = command:read("*a")
print(response)

And this is what I got back…

./mios/usr/lib/lua/ssl/https.lua:_VERSION = "0.4"
./rom/usr/lib/lua/ltn12.lua:_M._VERSION = "LTN12 1.0.3"
./rom/usr/lib/lua/luci/ltn12.lua:_VERSION = "LTN12 1.0.1"
./rom/usr/lib/lua/luci/model/uci.lua:APIVERSION = uci.APIVERSION
./rom/usr/lib/lua/soap/server.lua:_VERSION = "LuaSOAP 2.0.1 service helping functions"
./rom/usr/lib/lua/soap.lua:_VERSION = "LuaSOAP 2.0.1"
./rom/usr/lib/lua/socket/url.lua:_M._VERSION = "URL 1.0.3"
./rom/usr/lib/lua/ssl/https.lua: _VERSION = "0.8",
./rom/usr/lib/lua/ssl.lua: _VERSION = "0.8",
./tmp/upnp-event-proxy.lua:local API_VERSION = "3"
./usr/lib/lua/ltn12.lua:_M._VERSION = "LTN12 1.0.3"
./usr/lib/lua/luci/ltn12.lua:_VERSION = "LTN12 1.0.1"
./usr/lib/lua/luci/model/uci.lua:APIVERSION = uci.APIVERSION
./usr/lib/lua/soap/server.lua:_VERSION = "LuaSOAP 2.0.1 service helping functions"
./usr/lib/lua/soap.lua:_VERSION = "LuaSOAP 2.0.1"
./usr/lib/lua/socket/url.lua:_M._VERSION = "URL 1.0.3"
./usr/lib/lua/ssl.lua: _VERSION = "0.8"

Does anyone know what all the different areas are for, and also why at times there are different versions ? You’ll notice they have https.lua in 3 places, between v0.4 and v0.8 ?!!??

From what I understood is the run time looks first at /mios/usr/lib, then /usr/lib. The /rom is a read only that I think are used for factory reset only.

I have no idea why the old https.lua is in /mios/usr/lib, but we did ask if it can be removed in the 7.32 release so the 0.8 version gets used to run time, but that has not happened yet.

Hey @reneboer

Thanks for that update, considering the current situation, do you foresee any reason why the following wouldn’t work and/or cause an issue ? (Just copy the latest version over from one location, so they are all the same ?)

cp /rom/usr/lib/lua/ssl/https.lua /mios/usr/lib/lua/ssl/

Well, make sure you make a copy the version in /mios/lib first. Then overwrite, reboot and see what happens. Just make sure you have a path back.

Cheers Rene
