A server add-on that tells the host what datablock is being sent to clients

[Demian]

Some add-on(s) I have enabled on my server randomly crash people who are loading that datablock (when connecting) and considering the number of add-ons I have enabled, trying to figure out what add-on it is would take forever. Does an add-on exist that tells the host (in the console) the name of the datablock being sent to a connecting client? This way I could easily check what datablock caused the client to disconnect.

Unfortunately, no. However you can see the last received datablocks on the client side if you enable trace, it'll show something like Entering onDatablockObjectReceived(index, total).

I'm assuming this is what happens:

1) start writing packet
2) write 1 or 2 datablocks, currently at position 967
3) 967 is less than 1024, write next datablock
4) next datablock is really big and overflows the buffer of 1500 byte
5) corrupted packet is sent to client, crash

Basically the same problem as loading getting stuck.

do you happen to have port's footstep sounds mod enabled

p sure this is not what is happening, the only time i have encountered this is when a field from JumpSound was removed and some people (not all) were crashing because of it

No.

p sure this is not what is happening, the only time i have encountered this is when a field from JumpSound was removed and some people (not all) were crashing because of it

The weird thing is that clients do get in if they try enough times.

I'm pretty sure that's what's happening, it's also why it happens seemingly randomly. Eventually someone will say something in chat or any other event happens which causes it to start writing the big datablock at almost the end of a packet.

For example, if you're loading files in a server with noone talking, and send a ~50-60 character text message at the right time, everyone's load will break.

Datablocks can be quite big so they suffer from the same problem.

[Gytyyhgfffff]

wait demian are you talking about something like a crash that sends clients to desktop or are we talking about a load freeze

[Zeblote]

wait demian are you talking about something like a crash that sends clients to desktop or are we talking about a load freeze

Loading files will just stop on a corrupted packet, but a datablock event is expected to have an exact structure. If it doesn't, blockland can easily crash.

[Demian]

I have no idea. All I know is that the clients disconnect.

Sounds to me like the datablock loading system is fundamentally flawed if you crash clients by sending a chat message.

[Zeblote]

And... you didn't ask them what happened?

[Demian]

And... you didn't ask them what happened?

Few clients come back after the second crash and if they do they're only in for a second or two before another crash. Not enough time to chat. I also can't contact them outside my server because RTB IRC is no longer a thing.

[Conan]

it would help considerably if someone could tell you what the error message the popup dialog says

i used to have issues like this but they were always tracable to some vehicle addon or datablock being incorrectly overwritten or written - namely, the same datablock is being told to use a different .dts after being initialized with a different one. try disabling your vehicles list and see if that's the problem

[Zeblote]

Sounds to me like the datablock loading system is fundamentally flawed if you crash clients by sending a chat message.

The system essentially work like this:

while(event queue not empty)
{
    if(current position in buffer > 1024)
        break

    write next event to buffer
}

The buffer is 1500 byte long. If you start writing a 700 byte event at position 900 the packet will be corrupted.

This is why loading files used to break if you reset the minigame and similar stuff.
