 CHANGELOG
 ---------
+
+README: FreeBSD execution needs mailer (not found), sudo missing, bash needed, sed missing (see if StripQuotes mandatory)
+
+! XX Mar 2016: obackup v2.0 released
+- Added optional statistics for installer
+- Added an option to ignore knownhosts for ssh connections (use with caution, this can lead to a security issue)
+- Improved mail fallback
+- More logging enhancements
+- Improved upgrade script
+- Revamped rsync patterns to allow include and exclude patterns
+- Better SQL and file backup task separation (rotate copies and warnings are defined for sql and/or file)
+- Added reverse backup, now backups can be local, pushed or pulled to or from a remote system
+- Better fallback for SendAlert even if disk full
+- Added an alert email sent on warnings while backup script is running
+- Way better logging of errors in _GetDirectoriesSizeX, _BackupDatabaseX, _CreateStorageDirectoriesX
+- Added bogus config file checks & environment checks
+- Full code refactoring to use local and remote code once
+- Fully merged codebase with osync
+	- Added (much) more verbose debugging (and possibility to remove debug code to gain speed)
+	- Replace child_pid by $? directly, add a better sub process killer in TrapQuit
+	- Added some automatic checks in code, for _DEBUG mode (and _PARANOIA_DEBUG now)
+	- Improved Logging
+	- Updated obackup to be fully compliant with coding style
+- Fixed creation of bogus subdirectories in some cases
+- A long list of minor improvements and bug fixes
+
+v0-1.x - Jan 2013 - Oct 2015
 - New function to kill child processes
 - Fixed no_maxtime not honored
 - Improved some logging, also added highlighting to stdout errors

+
+Change old scripts with
+for i in $(grep -r '#!/bin/bash' * |cut -f1 -d':'); do sed -i 's&#!/bin/bash&#!/usr/bin/env bash&g' $i; done
+
+
+type instead of type -p for bash test (other shells don't know -p)

+
+Using tabs
+Transform old shell scripts using unexpand command
+
+++++++ Comments
+
+Some command # comment
+## Some comment on a new line
+################################################# Some separation
+
+++++++ Work comments
+
+Whenever there is some idea to postpone, use #TODO[-version]:[dev-name:] some remark
+A marker must be left where on the line a dev is working (when the work isn't finished). Marker is #WIP:dev-name: some remark
+dev-name is mandatory if more than one person is coding
+Example: #TODO-v2.1:deajan: need to do something
+
+++++++ Variables
+
+All local variables are lowercase, separated by _ (ex: low_wait)
+All global variables full upercase, separated by _ (ex: EXEC_TIME)
+All environment variables (verbose, silent, debug, etc) have prefix _ and are full upercase, separated by _ (ex: _PARANOIA_DEBUG)
+
+++++++ Functions
+
+Every word in a function begins with an uppercase (ex: SomeFunctionDoesThings)
+
+Define functions this way. Use sed ':a;N;$!ba;s/\n{\n/ {\n/g' to adapt when opening bracket is on a new line.
+
+function something {
+	
+}
+
+If function has some arguments, use local variable names that are more readable than $1...$n. Explain via comments what those variables contain if needed.
+
+function anotherthing {
+	local var_name="${1}"
+	local other_var_name="${2}" # This variable contains stuff
+}
+
+Functions should always have return status
+function thirdthing {
+	some_command
+	return $?
+}
+
+++++++ Sub functions
+
+When a function is a subroutine of another function, it is called _SomethingAsSubFunction
+
+++++++ Function argument check
+
+Bash does not provide any checks against missing function arguments. Also, missing quotes can lead to an inconsistent number of arguments.
+Every function call will be checked by __CheckArguments which takes the number of arguments, $# (the real number of args given), the parent function name and the parent function's arguments.
+__CheckArguments will trigger a critical error if number of arguments if incorrect. This will also prevent silent typo errors.
+Ex:
+
+function Something {
+	local some="${1}"
+	local other="${2}"
+	local args="${3}"
+	__CheckArguments 3 $# $FUNCNAME "$*"
+
+__CheckArguments will only trigger if script is called with DEBUG=yes
+Also, with PARANOIA_DEBUG=yes, __CheckArguments will recount all arguments given by "$*" and compare. This can mislead if arguments contain spaces.
+
+++++++ If statements
+
+If statements will be fully written (word "if" must be used). then is written on the same line.
+(Use sed ':a;N;$!ba;s/]\n\t*then/]; then/g' to convert files to this format... Replace "],new line, zero or more tabs, then" by "; then")
+if [ something ]; then
+	stuff
+else
+	other stuff
+fi
+
+++++++ Logging
+
+A logging function is available with the following levels of logging:
+
+- DEBUG: Only log this when DEBUG flas is set in program. Any command forged for eval should be logged by this.
+- NOTICE: Standard messages
+- WARN: Requires attention
+- ERROR: Program produced an error but continues execution
+- CRITICAL: Program execution is halted
+
+++++++ Eval
+
+Most commands should be logged to a tmp file.
+The basic way of doing is:
+
+cmd='"something '$somevar'" > some_file 2>&1'
+eval $cmd &
+WaitForTaskCompletion $! 0 0 $FUNCNAME
+
+Remote commands should exist as:
+
+cmd=$SSH_CMD' "some; commands \"'$VARIABLE'\" some; other; commands" > some_file 2>&1'
+
+++++++ File variables
+
+All eval cmd should exit their content to a file called "$RUNDIR/osync.$FUNCNAME.$SCRIPT_PID"
+Dots are used instead of '_' so variables can be separated with a forbidden char in variables, so they get detected.
+
+++++++ Finding code errors
+
+Use shellcheck.net now and then (ignore SC2086 in our case)
+
+Use a low tech approach to find uneven number of quotes per line
+
+tr -cd "'\n" < my_bash_file.sh | awk 'length%2==1 {print NR, $0}'
+tr -cd "\"\n" < my_bash_file.sh | awk 'length%2==1 {print NR, $0}'
+
+++++++ ofunctions
+
+As obackup and osync share alot of common functions, ofunctions.sh will host all shared code.
+Dev programs n_osync.sh and n_obackup.sh will source ofunctions.sh
+Release programs will still include ofunctions.sh in order to enhance ease of use.
