* Validate modified code using Shellcheck & Strict Bash
* Added and/or elaborated more comments
* scanlist() should exit if /etc/pihole is not available
* Add `export LC_CTYPE=C` to prevent extreme grep slowdown
* Consider "domain.com#comment" an exact match
* Add specialised wildcard searching grep
* Optimise and simplify queryFunc() for readability
* Replace IDN `python` parsing with `idn2`, as `python` is not guaranteed to be available
* Use ${COL_BOLD} when printing filenames
If Pi-Hole is behind a reverse proxy that uses SSL, then the block page will not load resources such as `blockingpage.css` and `jquery.min.js` as the insecure `http://` is hard coded. Browsers will block attempts to load insecure resources if the page is loaded of SSL.
The fix is acheived by checking `$_SERVER['HTTPS']` and setting the variable `$proto` to either `http` or `https`. The harcoded `http` is replaced by the contents of this variable.
* Remove WHITELIST_COMMAND
* Place IPv4/IPv6 availability test underneath setupVars.conf source
* Improved clarity on comments
* Define default lookupDomain on local line
* Use `getent hosts` instead of nslookup (faster)
* Make gravity_DNSLookup() function more readable
* Use bold on "Neutrino emissions detected"
* Swap conditionals around on adlists file handling
* Add comments to both gravity_Collapse() `awk`s
* Removed unnecessary "${str}" from gravity_Pull()
* Merge function variables into local line
* Place .phgbp suffice on mktemp, so patternbuffers can be cleaned up all at once in gravity_Cleanup()
* Removed success="false" from $httpCode case, placed empty success var in local
* Reordered $httpCode case numerically because I can
* Provide error if Dnsmasq format list is being parsed
* Remove IPv4 check when determining URL list (too slow on large lists)
* Check ${#sources[@]} to ensure we're checking the number of entries and not the character count
* Define empty plural in local line, removing unnecessary plural=;
* Optimised readability of gravity_Whitelist()
* Removed uninformative "Nothing to blacklist"/"No wildcards used" text
* Optimised parsing of domains into hosts format on IPv6 enabled servers
* Ensure /etc/hostname is non-zero
* Use `: >` instead of `rm` as consistent with the rest of the script
* Ensured that gravity_Cleanup() removes ${localList}.tmp
* Optimised readability of gravity_ParseUserDomains()
* Moved dnsRestart to ${var} case statement, renaming it to dnsRestartType for readability
* Set default $listType to ensure script passes "bash strict mode"
* Shift default dnsRestart value into unset default parameter expansion value
* Change nslookup timeout to 5 seconds
* Use &> instead of >
* Standardise plural code
* Update some comments
* Add "000" when connection is refused
* Condense adblock detection logic
* Add Dnsmasq format detection and parsing logic
* Removed unnecessary echo
* Add dnsWasOffline variable to ensure that if DNS service has been stopped, that it doesn't start and also get reloaded
* Merge development OpenVPN code
* Determine which domain to resolve depending on existence of $localList
* Re-add code to remove $localList, preventing duplicate local entries
* Minor shellcheck validation fix
Domains with caps pass off as unique. It is necessary for proper duplicate removal.
Example:
::: /etc/pihole/list.preEventHorizon (2 results)
adsatt.abcnews.starwave.com
Adsatt.ABCNews.starwave.com
* Comment file for review-ability
* Add BOLD and UNDERLINE options
* Select most readable colours out of LIGHT/DARK options
* Provide empty variables for `set -u`
* Deprecate unnecessary variables
* Correct colours for TICK/CROSS/DONE
* Escape r twice and add ESC to OVER
* Make colfile readonly, and use path of PI_HOLE_SCRIPT_DIR
* Rename piholeStatus function to statusFunc for function name consistency
* Replace superseded netstat command with nc
* Perform addn-hosts check using a single grep subshell
* Add/update code comments
* Change resolver check to test for pi.hole
* Make resolver check timeout after 10 seconds
* Use > instead of &> where appropriate
* Make resolver check sleep for 30 seconds (effectively waiting up to 50s for dnsmasq to be resolvable)
* Provide confirmation upon success of resolver check availability
* Quotes and Braced remaining variables as appropriate
* Removed duplicate local
