Simplified the process of adding lines to AC_AUTOMATA_t.
Use the ndpi_string_to_automa() function to add patterns with domain names.
For other cases can use ndpi_add_string_value_to_automa().
ac_automata_feature(ac_automa, AC_FEATURE_LC) allows adding
and compare data in a case insensitive manner. For mandatory pattern comparison
from the end of the line, the "ac_pattern.rep.at_end=1" flag is used.
This eliminated unnecessary conversions to lowercase and adding "$" for
end-of-line matching in domain name patterns.
ac_match_handler() has been renamed ac_domain_match_handler() and has been greatly simplified.
ac_domain_match_handler() looks for the template with the highest domain level.
For special cases it is possible to manually specify the domain level.
Added test for checking ambiguous domain names like:
- short.weixin.qq.com is QQ, not Wechat
- instagram.faae1-1.fna.fbcdn.net is Instagram, not Facebook
If you specify a NULL handler when creating the AC_AUTOMATA_t structure,
then a pattern with the maximum length that satisfies the search conditions will be found
(exact match, from the beginning of the string, from the end of the string, or a substring).
Added debugging for ac_automata_search.
To do this, you need to enable debugging globally using ac_automata_enable_debug(1) and
enable debugging in the AC_AUTOMATA_t structure using ac_automata_name("name", AC_FEATURE_DEBUG).
The search will display "name" and a list of matching patterns.
Running "AHO_DEBUG=1 ndpiReader ..." will show the lines that were searched for templates
and which templates were found.
The ac_automata_dump() prototype has been changed. Now it outputs data to a file.
If it is specified as NULL, then the output will be directed to stdout.
If you need to get data as a string, then use open_memstream().
Added the ability to run individual tests via the do.sh script
