SHORT FUTURE IMPROVEMENTS
-------------------------
- Rewrite rsync exclude patterns using \"pattern\" instead of escaped chars
- Clean most of recursive task creation code
KNOWN ISSUES
------------
@ -11,16 +5,27 @@ KNOWN ISSUES
- Bandwidth parameter is ignored for SQL backups
- Missing symlink support when run from MSYS environment
UNDER WORK
----------
- Commands like cp should have their stderr redirected to log file
- Mysqldump must be checked for not telling success if a table is damaged (also check for event table error)
- Mysqldump commands error msg must be logged
CHANGELOG
---------
README: FreeBSD execution needs mailer (not found), sudo missing, bash needed, sed missing (see if StripQuotes mandatory)
! XX Dec 2015: obackup v2.0 released
- 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
- A long list of minor improvements
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

Coding style used for my bash projects (v2.1 Oct 2015)
++++++ Header
Always use the following header
----BEGIN HEADER
#!/usr/bin/env bash
PROGRAM="program-name" # Long description
AUTHOR="(L) 20XX-20YY by Orsiris \"Ozy\" de Jong"
CONTACT="http://www.example.com me@example.com"
PROGRAM_BUILD=YYYYMMDDVV
## Optional instructions
----END HEADER
Using bind style versionning:
YYYYMMDDVV (Year, Month, Day, Revision): Example: 2015012402 = 2nd revision of 24 Jan 2015
#!/usr/bin/env bash instead of #!/bin/bash
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' $i; done
type instead of type -p for bash test (other shells don't know -p)
++++++ Indentation
Using tabs
Transform old shell scripts using unexpand command
++++++ Comments
Some command # comment
## Some comment on a new line
################################################# Some separation
++++++ Work comments
Whenever there is some idea to postpone, use #TODO[-version]:[dev-name:] some remark
A marker must be left where on the line a dev is working (when the work isn't finished). Marker is #WIP:dev-name: some remark
dev-name is mandatory if more than one person is coding
Example: #TODO-v2.1:deajan: need to do something
++++++ Variables
All local variables are lowercase, separated by _ (ex: low_wait)
All global variables full upercase, separated by _ (ex: EXEC_TIME)
All environment variables (verbose, silent, debug, etc) have prefix _ and are full upercase, separated by _ (ex: _PARANOIA_DEBUG)
++++++ Functions
Every word in a function begins with an uppercase (ex: SomeFunctionDoesThings)
Define functions this way. Use sed ':a;N;$!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.

## You can specify a RSA key (please use full path). If not defined, the default ~/.ssh/id_rsa will be used. See documentation for further information.
SSH_RSA_PRIVATE_KEY="/root/.ssh/id_rsa.srvmailing"
## The following options allow this Obackup instance to connect to a remote system via an ssh tunnel.
## Needs public RSA key need to be put into ~/.ssh/authorized_keys in remote users home directory.

## SQL Dump compression should be done on remote side but can also be done locally to lower remote system usage (will take more bandwidth, check for ssh compression)
COMPRESSION_REMOTE=yes
###### FILES SPECIFIC OPTIONS
## ---------- FILES BACKUP OPTIONS
## File backups are divided in tasks. Every directory in DIRECTORY_LIST will be processed as a unique task.
## Every subdirectory of each directory in RECURSIVE_DIRECTORY_LIST will be processed as a unique task.
## Example: RECURSIVE_DIRECTORY_LIST="/home;/var" will create backup tasks tasks "/home/dir1, "/home/dir2", ... "/home/dirN", "/var/log", "/var/lib"... "/var/something".
## You can exclude directories from the avove backup task creation, ex: avoid backing up "/home/dir2" by adding it to RECURSIVE_EXCLUDE_LIST.
## Directories backup list. List of semicolon separated directories that will be backed up recursively. Every directory will be processed as one backup task.
DIRECTORIES_SIMPLE_LIST="/var/named;/var/lib"
## Directories backup list. List of semicolon separated directories that will be backed up.
DIRECTORY_LIST="/var/named"
RECURSIVE_DIRECTORY_LIST="/home"
RECURSIVE_EXCLUDE_LIST="/home/backupuser;/home/lost+found"
## There's a special backup schema in Obackup called 'backup task division' which creates one backup task per level 1 subdirectory of a directory.
## This is VERY useful to backup multiple virtualhosts as separate tasks without having to specify each one separately.
## This may also be useful dividing big data directories in subdirectories tasks.
## Directories backup task division backup: Semicolon separated directories of which every level 1 subdirectory will be backed up recursively as a separate backup task.
## Example: "/home;/var" will create tasks "/home/dir1", "/home/dir2", ... "/home/dirN", "/var/log", "/var/lib"... "/var/whatever"
DIRECTORIES_RECURSE_LIST="/home"
## You may optionally exclude subdirectories from task division. On the above example you could exclude /home/dir2 by adding it to DIRECTORIES_RECURSE_EXCLUDE_LIST
DIRECTORIES_RECURSE_EXCLUDE_LIST="/home/backupuser;/home/lost+found"
