Using Amule 2.2.2 compiled from source on Ubuntu Intrepid AMD64.

Didn't crash anything but I couldn't connect to the webserver.

Known issue, and will be fixed in 2.2.3.

Until then you may change the condition 'fd > 2' to 'fd > 0' in WebInterface.cpp at lines 95 and 116.

[jpv950]

Thanks for the heads up. I still have this problem with SVN r9248 and your fix doesn't seem to work, unless I did something wrong.

As you may see, there are 2 conditions that triggers this assertion:
* fd < 0 (technically possible since fd is an integer)
* fd > 1024

So, either you have more than 1023 sockets opened at the same time, or something got completely broken. Can you do "bt full" to see what value fd have?

[jpv950]

I got it. The assertion condition should be changed to fd >= 0, otherwise the webserver crashes when launched by amule itself.

Two questions:

Shouldn't this be changed in SVN already, according to GonoszTopi comments? I don't see it. Also, like I said, it must be changed to fd>=0 and not fd>0 (since stdin can be piped, etc).

Is the second assertion condition really correct, fd < FD_SETSIZE? FD_SETSIZE seems to be the array length for storing file descriptors, why would that be related to the file descriptor value itself? Just checking on this.

[jpv950]

Oops, spoke too soon, another webserver crash on a different assertion when connecting. I'll take a better  look at it.

You should be checking man page for select() call.

My fault, I skipped the '=' sign somehow.

It was already, but only in trunk. Since rev. 9252, it's in the 2.2x branch too.

[jpv950]

So with rev. 9252 that problem is fixed but I have the new assertion failure I just mentioned.

This happens when connecting to the webserver.

[jpv950]

Still only crashes when launching amuleweb automatically with amule.
