Component/s: Engine, SVCMGR, TRACEMGR
Affects Version/s: 4.0 Initial
Fix Version/s: None

File Attachments: 1. File delete-from-mon_statements_302_vs-400_-_trace-and-console.7z (1 kB)

QA Status: No test

 Description  « Hide
Create two databases, one in 3.0.2 and second in 4.0.
Run following scenario on each of them:

1) launch ISQL and give it to execute script:
recreate view v_mons as
    mon$statement_id as sttm_id,
    mon$state as state_id,
    mon$stat_id as stat_id,
    mon$sql_text as sql_txt
from mon$statements
where mon$attachment_id != current_connection

recreate table test(id int primary key);
insert into test(id) values(1);

set term ^;
execute block as
    execute statement ('insert into test(id) values(?)') (1)
    on external
        as user current_user
           password 'masterkey'
           role right(uuid_to_char(gen_uuid()),12)
set term ;^
(ISQL will fall into infinite pause thus we can do another thisng - see below)

2) launch in 2nd window trace with following config:
database = %[\\/]security4.fdb
  enabled = false

database = #((%[\\/](e40).fdb)|(e40))
  enabled = true
  time_threshold = 0
  log_initfini = false

  log_statement_finish = true

  log_errors = true
  max_sql_length = 16300


3) run in 3rd window following:

echo set count on; delete from v_mons;|C:\MIX\firebird\fb40\isql /:e40

Console output and trace content in 4.0 is valuable shorter (and contains less info) comparing to 3.0.2 -- see attached .7z
Checked on WI-V3.0.2.32708 & WI-T4.0.0.633, mode = Classic & Super.
