# title: Support backup of encrypted databases
# decription:
# THIS TEST USES 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.
#
# After test database will be created, we try to encrypt it 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 backup of encrypted database + restore.
#
# Then we make snapshot of firebird.log, run 'gfix -v -full' of restored database and once again take snapshot of firebird.log.
# Comparison of these two logs is result of validation. It should contain line about start and line with finish info.
# The latter must look like this: "Validation finished: 0 errors, 0 warnings, 0 fixed"
#
# Checked on:
# 40sS, build 4.0.0.1487: OK, 6.552s.
# 40sC, build 4.0.0.1421: OK, 11.812s.
# 40Cs, build 4.0.0.1485: OK, 8.097s.
#
# 15.04.2021. Adapted for run both on Windows and Linux. Checked on:
# Windows: 4.0.0.2416
# Linux: 4.0.0.2416

# # WARNING! Do NOT use 'connection_obj.execute_immediate()' for ALTER DATABASE ENCRYPT... command!
# # There is bug in FB driver which leads this command to fail with 'token unknown' message
# # The reason is that execute_immediate() silently set client dialect = 0 and any encryption statement
# # can not be used for such value of client dialect.
# # One need to to use only cursor_obj.execute() for encryption!
