Call server.config() in plugin crash process.

[chtotut]

Try start awebot with quote plugin. Call server.config() from this srting crash process with Process didn't exit successfully:target/debug/awebot(signal: 4). In plugin did not work Server trait functions. Call server.config() from awebot work.

Rust version: rustc 1.0.0-nightly (083b8a404 2015-04-05) (built 2015-04-05)

Do you have a proper config.json file in your working directory that has a nickname declared? If you don't, it will cause the program to panic because there's no nickname for the bot to identify with.

Here's an example config.json:

{
    "owners": ["awe"],
    "nickname": "awebot",
    "alt_nicks": ["awebot_"],
    "server": "irc.pdgn.co",
    "use_ssl": true,
    "channels": ["#pdgn"],
    "options": {}
}

You can find other options here. The only required options are the nickname and the server. Everything else has defaults.

[chtotut]

Yes I have, It will work if comment server.config() in plugin code.

[aatxe]

Can you get a backtrace with gdb or lldb?

[chtotut]

src/lib.rs:34:

let resp = if chan == server.config().nickname() {

sry, I did not use gdb before. Is this info need?:

Judging from this, the problem doesn't seem to be with that line. I'm encountering similar issues now trying to use the quote plugin, but my backtrace differs from yours. I'll need to investigate further.

[aatxe]

Whatever issue I was having before but was vague about was resolved, but I am now reproducing this issue with server.config() calls on Linux.

[aatxe]

This issue was caused by differences between the Server trait in irc compiled into the plugins versus compiled into the awebot core. It was resolved in 70190bffac2f9ee732c7f7b96023b671b0f1f1e8.
