client_buffer_size reset to 1

[alitaker]

Right after running mlnet, _client_buffersize gets reset to 1 in the download.ini config file. The parameter is not taken into account if I change it to anything more than 50.000. In fact I keep getting errors like:

[TCP_BS]: BUFFER OVERFLOW 43648+27360> 50000 MESSAGE: [(107)(40)(173)(210)(238)(120)(90)(183)(61)(187)(199)(31)(58)(195)(225)(89)(163)(255)(49)(100)...]

which clearly indicates that the buffer size is at 50.000

Only recompiling with line 1873 of src/daemon/common/commonOptions.ml changed, seem to have mlnet use a different value:

 option_hook client_buffer_size (fun _ ->
      TcpBufferedSocket.max_buffer_size := max 500000 !!client_buffer_size

I also tried different OCaml versions with the same result.

Any ideas?

Thank you

I do not confirm. I have 1500 000 and no errors.

Could it be an error in the download.ini file? I don't know where to look as it's working like a charm after compiling mlnet with a hard coded default buffer size of 500.000

See mldonkey/docs/ChangeLog.old 2007/03/04 5765: Change hard-coded maximum value for client_buffer_size

• default stays at 500.000
• for high-volume links raise this value to 1.000.000 or higher

Mmmh, t

See mldonkey/docs/ChangeLog.old 2007/03/04 5765: Change hard-coded maximum value for client_buffer_size

* default stays at 500.000

* for high-volume links raise this value to 1.000.000 or higher

Ok, but if something is wrong in the downloads.ini, it falls back to 50.000:

  option_hook client_buffer_size (fun _ ->
      TcpBufferedSocket.max_buffer_size := max 50000 !!client_buffer_size
  );

Still couldn't find what was wrong in my downloads.ini though: anyway now it's working as expected.

Thanx
