#!/usr/bin/perl
# 
# This handles moving around and managing files on Anvil! nodes, DR hosts and Striker dashboards.
# 
# When this is called (periodically by the daemon of after an upload / ISO generation);
# - 1. Check 'incoming/' for files. For any found, generate an md5sum and see if the file name and sum match 
#      anything in the database from any host;
#      - If so, update/add an entry in 'file_locations'
#      - If not, create a new entry in 'files' and then add the first entry in 'file_locations'
# - 2. Check 'file_locations' for any files on this system, and verify they exist still. 
#      - If not, check the other files for one with a matching md5sum. If found, handle as a rename.
#      - If not found at all, search for the file according to the search rules and copy to here if found.
#      - If not found anywhere, remove it from 'file_locations' and send an alert.
#      - If found, check the size. If it differs, recalculate the md5sum.
# - 3. If called with '--rename --file <filename> --to <newname>', rename the file and update 'files'.
# - 4. If called with '--delete', remove from 'file_locations' and then remove from the local storage. If 
#      also used with '--everywhere', then all copies on all systems we know about will be deleted. This is 
#      done by registering a job against all known hosts. As such, if this is called and the target file 
#      doesn't exist, it just clears the job and then exits.
# - 5. If called with '--is-script=[0|1]', mark as 'script' in the 'files' table and set/remove the executable bit.
#
# Exit codes;
# 0 = Normal exit or md5sum of this program changed and it exited to reload.
# 1 = No databases available.
# 2 = Another process that is still running has picked up this job.
# 3 = No filename specified when needed by another switch.
# 4 = Request to change the file name but the new name wasn't given.
# 5 = The file specified was not found.
# 6 = The file to delete is not under '/mnt/shared/'.

# This looks to see if there are any entries in 'file_locations' for us that, the pointed to file, doesn't 
# exist on this machine. For those entries, we will search for the file on other machines. The one exception
# is server definition files. For those, we write the file out from the server's 'definition' table entry.
# 
# When a missing entry is found, and an entry doesn't exist, the file will be found (if possible) and copied
# to this houst. Only machines on the same subnet are searched. The search pattern is; 
# 
# Nodes;   1. Check for the file on the peer.
#          2. Check for the file on Strikers, in alphabetical order.
#          3. Check for the file on DR host, if available.
#          4. Check other nodes, in alphabetical order.
#          5. Check other DR hosts, in alphabetical order.
# Striker; 1. Check for the file on other Strikers, in alphabetical order.
#          2. Check for the file on DR hosts, if available
#          3. Check for the file on Anvil! nodes.
# DR Host; 1. Check for the file on Strikers, in alphabetical order.
#          2. Check for the file on Anvil! nodes.
# * If a file can't be found, it will try again every so often until it is found.
# * When a file is found, it is copied to '/mnt/shared/incoming'. Only when the file has arrived and the 
#   md5sum matches. At this point, it is moved into the proper directory.
