# title: NBACKUP locks db file on error
# decription:
# We create level-0 copy of test DB (so called "stand-by DB") and obtain DB backup GUID for just performed action.
# Then we create incremental copy using this GUID ("nbk_level_1") and obtain new DB backup GUID again.
# After this we repeat - create next incrementa copy using this (new) GUID ("nbk_level_2").
#
# (note: cursor for 'select h.rdb$guid from rdb$backup_history h order by h.rdb$backup_id desc rows 1' can be used
# to get last database backup GUID instead of running 'gstat -h').
#
# Further, we try to apply two incrementa copies but in WRONG order of restore: specify <nbk_level_2> twise instead
# of proper order: <nbk_level_1> and after this - <nbk_level_2>.
#
# First and second attempts should issue THE SAME message:
# "Wrong order of backup files or invalid incremental backup file detected, file: <nbk_02>".
#
# We do this check both for NBACKUP and FBSVCMGR.
#
# Confirmed bug on 4.0.0.2000: second attempt to run restore using FBSVCMGR issues:
# =====
# Error opening database file: [disk]:\\path o\\standby_db.dfb
# process cannot access the file <nbk_level_2> because it is being used by another process
# =====
# - and file <nbk_level_2> could not be deleted after this until restart of FB.
#
# Works fine on 4.0.0.2025 CS/SS.
# 13.06.2020: adapted for use both in 3.x and 4.x; checked on 4.0.0.2037, 3.0.6.33307 - all OK.
#
# ::: NOTE :::
# bug has nothing with '-inplace' option that present only in FB 4.x - it was also in FB 3.x.
# Fix for 3.x was 11.06.2020 12:36, include in "aedc22: Fixed assert in Statement::freeClientData()",
# see: https://github.com/FirebirdSQL/firebird/commit/fdf758099c6872579ad6b825027fe81fea3ae1b5
#
# 20.01.2021. CRITICAL NOTE (detected when run tests against HQbird 33288, ServerMode = Classic).
# #########################
# Method "codecs.open()" must be used to process logs, instead of 'plain' open() !
# Any FB utility which have access problems with file can/will report *part* of error message in localized form.
# This text is not in utf-8 (at least in case of Windows) and thus can not be converted and correctly displayed:
# PROBLEM ON "ATTACH DATABASE".
# I/O ERROR DURING "CREATEFILE (OPEN)" OPERATION FOR FILE "C:/HQBWORK/1IMPORTANT/QA-RUNDAILY/FBT-REPO/TMP/BUGS.CORE_6319.FDB"
# -ERROR WHILE TRYING TO OPEN FILE
# <The process cannot access the file because the file is being occupied by another process.> // <<< CAN BE IN LOCALIZED FORM!
# SQLCODE:-902
#
# Because of this, fbt_db utility will fail on attempt to store in ANNOTATIONS table such message with "335544849 : Malformed string".
# The worst part is that no any other tests will be saved, i.e. we will have DB with EMPTY result, despite the fact that a problem
# occured only on one test (the reason is that fbt_db does all actions within the single transaction).
#
# Because of this all messages that are iussued by nbackup/fbsvcmgr or all other utilities must be handled using codecs.open()
# method with request to IGNORE all non-ascii character (do NOT try to show it) and take next one.
# Example: "with codecs.open( e.name, 'r', encoding = 'utf-8', errors = 'ignore' ) as f: ..."
#
# Checked (after replace "open(): with "codecs.open(... errors = 'ignore')" call) on:
# 4.0.0.2307 SS: 2.639s; 4.0.0.2324 CS: 3.610s; 3.0.8.33401 SS: 2.210s; 3.0.8.33401 CS: 3.400s.
