# title: Append the IP address of the remote host to error messages in firebird.log for TCP connections
# decription:
# Following actions are performed by this test:
#
# 1. Obtain current firebird.log and saves it to the file with name = 'tmp_2493_fblog_before.txt';
#
# 2. Asynchronously launch ISQL in child process with request to return client IP address (via asking context variable)
# and after this - do some 'heavy query' that for sure will take a lot of time and resources.
# Output is redirected to file with name = 'tmp_2493_isql.log' and will be parsed further (we'll search for client IP there).
#
# 3. Kill launched ISQL process after several seconds. At this point new message must appear in firebird.log and it MUST
# be in format described in the ticket. Because this abend will be detected by SERVER, format of message will be like this:
# (for TCPv4): INET/inet_error: read errno = 10054, client host = prog1, address = 127.0.0.1/4076, user = john
# (for TCPv6): INET/inet_error: read errno = 10054, client host = prog2, address = fe80::c40e:21ec:b5c7:8963/56831, user = mick
#
# 4. Wait several seconds and after it - obtain again firebird.log (new content) and save it in 'tmp_2493_fblog_after.txt'.
#
# 5. Make file comparison by calling method from standard Python tool - difflib. Result of this comparison will be stored
# in file with name 'tmp_2493_diff.txt'. This file will have several lines from which we are interested only for one which
# STARTS with "+" (PLUS sign) and does contain phrase 'INET/INET_ERROR'. Diff-file must contain only ONE such line.
#
# 6. Next we parse this line: remove "/" and "="characters from it and split then text into array of words:
# + INET inet_error read errno 10054 client host prog1 address 127.0.0.1 4417 user john ------- for IPv4
# 0 1 2 3 4 5 6 7 8 9 10 11 12 13
# + INET inet_error read errno 10054 client host prog2 address x::y:z:u:v 56831 user mick ------- for IPv6
# 7. Then we scan this array backward and check tokens for matching simple rules (N = array len):
# * token N-1 must be OS user name; this name can be followed by some kind of "suffix": "JOHN.-1.-1" - and we have to take only 1st word from it.
# NB: we current OS user using call of getpass.getuser(). It must be compared in case insensitive manner;
# * token N-2 is just word "user" (as is);
# * token N-3 is port number, it has to be positive value;
# * token N-4 is IP. It must be equal to rdb$get_context('SYSTEM','CLIENT_ADDRESS').
#
# This is how differences look in firebird.log:
# # 2.5.9:
# # INET/inet_error: read errno = 10054, client address = 127.0.0.1 3268, user ZOTOV.-1.-1
# # ^ ^ ^ ^
# # N-4 N-3 N-2 N-1
# # 3.0.4:
# # INET/inet_error: read errno = 10054, client host = csprog, address = 127.0.0.1 3298, user zotov
# # ^ ^ ^ ^
# # N-4 N-3 N-2 N-1
# # 3.0.8 and 4.0.0 RC1:
# # INET/inet_error: read errno = 10054, client host = csprog, address = fe80::fcf1:e33c:e924:969d%16/56887, user = zotov
# # INET/inet_error: read errno = 10054, client host = csprog, address = fe80::fcf1:e33c:e924:969d%16/56883, user = zotov
#
#
# Checked on WI-V3.0.0.32272 x86 and amd64, OS = Windows XP and 8.1, TCPv4 and TCPv6; fdb version = 1.5, Python 2.7 and 3.4.
# Checked 17.02.2018 after adding 2.5.9 to the list of avaliable versions:
# 2.5.9.27103: OK, 5.547s.
# 3.0.3.32837: OK, 7.079s.
# 3.0.4.32912: OK, 6.094s.
# 4.0.0.800: OK, 7.109s.
# 4.0.0.890: OK, 6.360s.
# ### NB ###
# First version of this test was implemented on Windows XP and Python 2.7.8, build 02-jul-2014 win32.
# Unfortunatelly, on Python 3.4 + Win 8.1 it is unable to use socket.inet_pton() call -exception raises with text:
# "AttributeError: 'module' object has no attribute 'inet_pton'".
# For that reason it was decided do NOT use calls of socket.inet_pton() and operate only with remote_address that can be easy
# received using built-in FB context variable. User-defined functions 'is_valid_ipv4' and 'is_valid_ipv6' are left here for
# possible further usage in some other tests.
#
# 20.02.2021: changed 'platform' attribute to Windows only. Content of firebird.log has no changes on Linux during this test run.
# Perhaps, this is temporary and another solution will be found/implemented. Sent letter to dimitr et al, 21.02.2021 08:20.
