* ahoсorasick. Code review. Part 2. (#1236)Vitaly Lavrov2021-07-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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
* Removed ht_hash as it is not used anymore. (#1220)Toni2021-06-29

* Speed and memory size optimisation (#1214)Vitaly Lavrov2021-06-23
| | | | | | | Removed bigram_automata, impossible_bigram_automata, trigram_automata. The ahocorasick structure is replaced with a bitmap. The bitmap size for ndpi_en_bigram is 176 bytes. The bitmap size for ndpi_en_trigram is 2201 bytes. On the test machine, the test execution time was reduced from 27.3 seconds to 24.7 (9%).
