[Pkg-javascript-devel] Bug#848823: node-ltx does not work with its main user node-node-xmpp

[Nicolas George]

Package: node-ltx
Version: 2.4.2-1
Severity: important

Dear Maintainer,

I tried using node-node-xmpp, and trying with the examples leads to this
error:

/tmp $ nodejs echo_bot.js
(node) sys is deprecated. Use util instead.
module.js:327
    throw err;
    ^

Error: Cannot find module 'ltx'
    at Function.Module._resolveFilename (module.js:325:15)
    at Function.Module._load (module.js:276:25)
    at Module.require (module.js:353:17)
    at require (internal/module.js:12:17)
    at Object.<anonymous> (/usr/lib/nodejs/node-xmpp/lib/xmpp/connection.js:4:11)
    at Module._compile (module.js:409:26)
    at Object.Module._extensions..js (module.js:416:10)
    at Module.load (module.js:343:32)
    at Function.Module._load (module.js:300:12)
    at Module.require (module.js:353:17)

(I had to fix a relative path in the echo_bot.js example.)

The infringing line in xmpp/connection.js is this:

var ltx = require('ltx');

And indeed, doing that with nodejs directly results in the same issue:

/tmp $ echo "var ltx = require('ltx');" | nodejs 
module.js:327
    throw err;
    ^

Error: Cannot find module 'ltx'
    at Function.Module._resolveFilename (module.js:325:15)
    at Function.Module._load (module.js:276:25)
    at Module.require (module.js:353:17)
    at require (internal/module.js:12:17)
    at [stdin]:1:11
    at Object.exports.runInThisContext (vm.js:54:17)
    at Object.<anonymous> ([stdin]-wrapper:6:22)
    at Module._compile (module.js:409:26)
    at node.js:579:27
    at nextTickCallbackWith0Args (node.js:420:9)

strace shows it tries to access these files:

stat("/usr/lib/nodejs/ltx", {st_mode=S_IFDIR|0755, st_size=4096, ...}) = 0
open("/usr/lib/nodejs/ltx/package.json", O_RDONLY|O_CLOEXEC) = -1 ENOENT
stat("/usr/lib/nodejs/ltx.js", 0x7ffc6fd397f0) = -1 ENOENT
stat("/usr/lib/nodejs/ltx.json", 0x7ffc6fd397f0) = -1 ENOENT
stat("/usr/lib/nodejs/ltx.node", 0x7ffc6fd397f0) = -1 ENOENT
open("/usr/lib/nodejs/ltx/package.json", O_RDONLY|O_CLOEXEC) = -1 ENOENT
stat("/usr/lib/nodejs/ltx/index.js", 0x7ffc6fd397f0) = -1 ENOENT
stat("/usr/lib/nodejs/ltx/index.json", 0x7ffc6fd397f0) = -1 ENOENT
stat("/usr/lib/nodejs/ltx/index.node", 0x7ffc6fd397f0) = -1 ENOENT

(ENOENT = No such file or directory, I truncated for readability)

The exact same thing happens with "require('node-xmpp')".

I do not know whether the bug is in node-node-xmpp or node-ltx, but I
suspect it is in the packaging of the later.
