Re: Migrating dissector to WS 1.12

["Helge Kruse" <Helge.Kruse () gmx net>]

Hi Pascal,

 

at first I’ve spotted two additional functions that are missing or have changed the semantic.

 

In old dissector I have a construct

       if (check_col(m_pinfo->cinfo, COL_PROTOCOL))

       {      // column is displayed

             col_set_str(m_pinfo->cinfo, COL_PROTOCOL, "my protocol");

       }

 

The check_col function is not available anymore. How to fill the protocol column.

 

And the second question is about TCP stream dissection. The function tcp_dissect_pdus has changed parameters and the 
signature of new_dissector_t isn’t clear. Wasn’t it the job of the get_pdu_len function to get the correct number of 
byte of a pdu?

 

Best regards

Helge

Hi,

I am migrating from WS 1.6 to WS 1.12 skipping all version between.
I have some code that uses functions that are not available in the
current version. How can I find how this functions are replaced by newer
functions?

Example: tvb_get_ephemeral_string()

 

This one is replaced by tvb_get_string_enc(wmem_packet_scope(),tvb,offset,length, ENC_ASCII | ENC_NA);

Conversions from older to newer APIs are not veery well documented unfortunately. You can easily find them by doing 
searches in git hitory, or if the list is not too long you can ask on this mailing list.

Regards,

Pascal.
