# title:        Unique constraint not working in encrypted database on first command
# decription:
#
#                   We create new database ('tmp_core_5673.fdb') and try to encrypt it using IBSurgeon Demo Encryption package
#                   ( https://ib-aid.com/download-demo-firebird-encryption-plugin/ ; https://ib-aid.com/download/crypt/CryptTest.zip )
#                   License file plugins\\dbcrypt.conf with unlimited expiration was provided by IBSurgeon to Firebird Foundation (FF).
#                   This file was preliminary stored in FF Test machine.
#                   Test assumes that this file and all neccessary libraries already were stored into FB_HOME and %FB_HOME%\\plugins.
#
#                   We create table with UNIQUE constraint, add some data to it and try to encrypt database using 'alter database encrypt with <plugin_name> ...'
#                   command (where <plugin_name> = dbcrypt - name of .dll in FB_HOME\\plugins\\  folder that implements encryption).
#                   Then we allow engine to complete this job - take delay about 1..2 seconds BEFORE detach from database.
#
#                   After this we make TWO attempts to insert duplicates and catch exceptions for each of them and print exception details.
#                   Expected result: TWO exception must occur here.
#
#                   ::: NB ::::
#                   Could not check reproducing of bug on FB 3.0.2 because there is no encryption plugin for this (too old) version.
#                   Decided only to ensure that exception will be catched on recent FB version for each attempt to insert duplicate.
#                   Checked on:
#                        4.0.0.1524: OK, 4.056s ;  4.0.0.1421: OK, 6.160s.
#                       3.0.5.33139: OK, 2.895s ; 3.0.5.33118: OK, 2.837s.
