OS : x86_64 GNU/Linux
App : szl 1.0 (http://code.google.com/p/szl/downloads/list)
Input :The input file is recordio format which is offer by szl, with 100
records in it. Each record has channel field, bug only 92 records have
refer_info.g_f.
Script : case_ok.szl, case_bad1.szl, base_bad2.szl
Question : the three cases are suppose to have same result , but it is not.
Case 1:
Input sawzall script :(case_ok.szl)
.....
1 proto "log_wap_access.proto"
2
3 pv_channel : table sum[channel:bytes] of int;
4
5 log : log_wap_access = input;
6 channel: bytes = ?{if(def(log.channel)) result log.channel; else result B"";};
7 emit pv_channel[channel] <- 1;
....
Input data :(input)
Run command :./szl case_ok.szl input --use_recordio=true --protocol_compiler=./protoc --protocol_compiler_plugin=./protoc-gen-szl --table_output=*
Result : pv_channel[WAP_SWEB_ACS] = 100
Case 2:
Input sawzall script :(case_bad1.szl)
....
1 proto "log_wap_access.proto"
2
3 pv_channel : table sum[channel:bytes] of int;
4
5 log : log_wap_access = input;
6 channel: bytes = ?{if(def(log.channel)) result log.channel; else result B"";};
7 emit pv_channel[channel] <- 1;
8
9 # this variable is not used
10 usless : uint = log.refer_info.g_f;
....
Input data :(input)
Run command :./szl case_bad1.szl input --use_recordio=true --protocol_compiler=./protoc --protocol_compiler_plugin=./protoc-gen-szl --table_output=*
Result: pv_channel[WAP_SWEB_ACS] = 92
pv_channel[] = 8
Case 3:
Input sawzall script :(case_bad2.szl)
....
1 proto "log_wap_access.proto"
2
3 pv_channel : table sum[channel:bytes] of int;
4
5 # this variable is not used
6 usless_table : table collection of log_wap_access;
7
8 log : log_wap_access = input;
9 channel: bytes = ?{if(def(log.channel)) result log.channel; else result B"";};
10 emit pv_channel[channel] <- 1;
....
Input data :(input)
Run command :./szl case_bad2.szl input --use_recordio=true --protocol_compiler=./protoc --protocol_compiler_plugin=./protoc-gen-szl --table_output=*
Result: pv_channel[WAP_SWEB_ACS] = 92
pv_channel[] = 8
