Re: Bug related to Bullseye bulletin board?

I'm not sure if this is the right place to post about it, as I think that Javascript code is correct, maybe it is a bug in the Javascript
interpreter.

The problem is that since upgraded to lastest build Synchronet (3.15 I think). Bullseye doesn't seem to be working rightly. Whatevet I select a bulletin to display it says "Invalid bulletin number". I switched the Bullseye program from the Baja one to the Javascript version, as I understand js better and could take a look to the code (the problem was still there, no matter the switch).

It looks like the problem is related to the File.position property, at
lines 41 and 42:

mode=file.readln();
filepos=file.position;

The former reads the first line of bullseye.cfg correctly, retrieving the number stored there, but them for some strange reason, the latter line stores in filepos the number -4. Being file.position the offset in bytes of the file and as the first line is just a character (4 bytes), it doesn't make much sense to be "-4", it should be "4". From that point the program won't work correctly as it will never enter in the loop:

file.position=filepos; // file.position=-4
i=0;
while((str=file.readln())!=null) {

If I change the first line with this one:

file.position=4;

The Bullseye starts working again as it should. So I think that it could be something wrong in the file seeking functions.

I don't know if this is a bug, but it's actually so weird.

It sounds like a bug, but I haven't been able to reproduce it here. What are the contents of your bullseye.cfg file?

If the first line is a single digit (e.g. 0), that should normally be 3 characters (3<CR><LF>), not 4. Maybe you could e-mail me your bullseye.cfg file as an attachment and I'll see if I can reproduce it here.

I emailed you my bullseye.cfg file. It's not different from the standard one.

Hm... What's the length of the file (in bytes)? I didn't receive the e-mail.

If the first line is a single digit (e.g. 0), that should normally be 3 characters (3<CR><LF>), not 4. Maybe you could e-mail me your bullseye.cfg file as an attachment and I'll see if I can reproduce it here.

You're right, so the file.filepos should be 12 (3 characters * 4 bytes =
+12 bytes offset). Even so, it does not make any sense to be -4.

4 bytes per character? No, it's ASCII - one byte per character, so after reading 3<CR><LF>, the file position should be 3. Unless you converted it to UTF-32?
