minetest mod Auth Redux
=======================
AUTH drop-in faster replacement for authentication handler in minetest.
Information
-----------
Auth Redux is a drop-in replacement for the builtin authentication handler
of Minetest. It is designed from the ground up to be robust and secure enough
for use on high-traffic Minetest servers, while also addressing a number of
outstanding engine bugs
Its **the most faster equilibrated authentication handler in minetest.** (its like
if you were using Redist or LevelDB but with very high stability).
![](screenshot.png)
## Technical information
------------------------
Auth Redux provides an efficient and scalable back-end solution for player
authentication, making it suitable for even the most demanding server
environments. It has been put to the test with a database of over 520,000 registered
users -- with no in-game overhead!
Recommended Enhancement: The DataMiner Mod extends the capabilities of Auth Redux,
providing comprehensive player and server statistics within a graphical user-interface,
in addition to an API for custom-tailored log analysis and reporting directly
from the command line.

#### Feature matrix metrics
Auth Redux is the most equilibrated faster authentication handler:
| Player Auth handler | re-joins | new join | set privilegies | database size | stability |
| ------------------- | ------------ | ----------- | ------------ | ----------- | ------------ |
| 5.0+ Builtin | 4.5 x Faster | 4 x Faster | 4.2 x Faster | 17% smaller | 100 x stable |
| 0.4.X Builtin | 592 x Faster | 3 x Faster | 633 x Faster | 32% smaller | 1000 x stable |
| sauth mod (sqlite) | 40 x Faster | 33x Faster | 48 x Faster | 32% smaller | 4 x stable |
| SQLite Builtin | 30 x Faster | 23x Faster | 40 x Faster | 30% smaller | 4 x stable |
| Redist Builtin | 8 x slower | 2 x slower | 1 x slower | unknow | 10 x stable |
| PostgreSQL Builtin | 35 x Faster | 33x Faster | 40 x Faster | 30% smaller | 4 x stable |
#### Full lua based code
Auth Redux is completely Lua-driven, with no external dependencies. It
interfaces seamlessly with Minetest's authentication handler API, therefore
no complicated setup or configuration is required. It is intended to be
compatible with all versions of Minetest 0.4.14+, providing server administrators
with both flexible and fine-grained access control.
#### increased security and bug free
It addressing following long time bugs without complicated dependencies:
* #5334 https://github.com/minetest/minetest/issues/5334
* #6783 https://github.com/minetest/minetest/issues/6783
* #4451 https://github.com/minetest/minetest/issues/4451
#### Dependencies:
* default
* formspecs (ActiveFormspecs Mod)
#### Documentation
Original documentation is on https://github.com/sorcerykid/auth_rx/wiki/Introduction
#### Technical features
* High-Performance Journaling System
To protect the master database against corruption and data loss, all
transactions are serially recorded within a journal, thereby reducing the
frequency and intensity of disk writes. In the event of a server crash or
power outage, any pending transactions are committed to the master database.
* Stateful Rule-Based Login Filtering
MARS is an easy-to-learn scripting language that affords a first line of
defense against unwanted visitors. Both restrictive and permissive security
models can be enforced via rulesets, allowing every login request to be
filtered according to conditional action-chains with custom error messages.
* Expanded Master Database Schema
The master database supports additional metadata to aid in reviewing and monitoring
login activity, including the timestamp of the first login, the total time
spent playing, the total number of player sessions, etc. This information
can prove invaluable for command-line reporting and analysis tools.
#### Integrated ruleset debugger
By entering the `/fdebug` command into chat (requires the "server privilege"),
you will be presented with a debugging console. The workspace consists of the
following elements:
![](screenshot-debugger.png)
* A. The "Show Client Output" option toggles whether to display the client output
panel. The "Show Debug Prompt" option toggles whether to insert debug status prompts
into the source code.
* B. This textarea contains the ruleset definition to be examined. Although Minetest
supports editing of text, it is strongly recommended to copy and paste your source
code into a full-fledged text editor.
* C. The client output panel renders error messages as they would appear within the
client. The status panel typically indicates whether the ruleset passed or failed,
as well as other debugging conditions.
* D. The "Save" button will export the current ruleset definition, overwriting
"greenlist.mt" in your world directory. The "Load" button will import an existing
ruleset definition from "greenlist.mt" for debugging.
* E. The "Process" button will process the ruleset definition according to the
selected login filtering criteria: Normal, New Account, or Wrong Password (thereby
changing the relevant preset variables).
* F. The preset variables are listed here with their corresponding values. These
values will never change except during the login filtering process, or unless
explicitly set in the panel below.
* G. The name and type of the selected variable is indicated here. The value can be
edited in the text field, and set with the "Set" button. The arrow buttons allow for
re-ordering any variable within the list.
Some variables, like $clock and $uptime, have an "Auto Update" option to toggle whether
the values should be derived from the system state. For a fully sandboxed environment,
you can disable this option.
The special `$__debug` variable gives you direct access to the MARS expression
interpreter. You can enter any valid expression, and the resulting value and type
will be displayed in the panel above (all variable types, except patterns, are
supported). This is particularly helpful for monitoring the values of certain
variables. To calculate the size of the $ip_names_list, for example, you would enter
```
size($ip_names_list)
```
Whenever a ruleset passes or fails, or if a syntax error is encountered, a debug
status prompt will be inserted into the source code below the line in question:
```
if $name->len() eq "administrator"`
# ====== ^ Line 12: Mismatched operands in ruleset^ ======
```
These breakpoints will be removed automatically when the ruleset definition is saved,
so there is no need to edit them out.
#### benchmarks
You can check the file [benchmark.txt](benchmark.txt) from where the
comparisons were made.
As these benchmarks reveal, there is no discernible benefit to using an SQLite3
backend for authentication over a flat-file database, whether in terms of
reliability or performance.
The cons of using LEvelDB or REdist is the unstability of those fast storage
authentication handlers, so auth_RX solves the problem and being more faster.
If anything, SQLite3/File/LevelDB databases are a hindrance when it comes to
random access of large volumes of data, and more than likely the culprit for
why some high-traffic servers lately are experiencing notable lag spikes
