10 months ago I just finished rewriting everything for the OpenComputer part and web part so it's fresh in my mind. Don't worry about asking too many questions I don't mind if it can help someone.
What version of python and flask are you using and anything that was installed via pip, setuptools, conda, or anything else? A pip freeze would probably work just fine instead of answering manually
The version of python used is Python 3.10.12 and for the requirements its just a standard pip3 install for flask and oracledb. Actually you also need the gunicorn package but this is only useful for putting the web server in production.
What modpack are you using? I take it GTNH based on this line
Yes, but the program is independent from the modpack, it can be used in any modpack as long as there is OpenComputer and AE2. The only purpose of this line is to use an alternative function developped by the GTNH dev to get the items from AE without making too much lag if you're running it on the GTNH modpack.
Can I get the script if you still have it you had mentioned in this issue https://github.com/PoroCoco/myaenetwork-Server/issues/3 ?
The only use for this script was to translate the gregtech items names as OpenComputer wasn't giving the actual name. However this is not needed anymore (at least for GTNH) as the devs fixed that and the correct items names are now returned. The only case where this could be useful would be for the other gregtech packs like NomiFactory, but I don't even know if this issue exists on the other modpacks anyway. If you really need it I can search for it, but I don't have to use it anymore.
Would you like me to show you my project once it's to a "working" point? I am planning to add remote access for whatever OC has access to in Gregtech: New Horizons within reason. And hopefully a GUI based program that makes OC robots easier to program via being able to visualize them moving via symbols the represent different actions (arrows for moving, a chest for interacting with any inventory and so fourth) in a voxel grid that represents the space around the robot in-game. The actions are following along a line that portrays the order of the actions. The user can see this line and can also choose to only certain parts on it making it easier to debug and develop.
Yes I'd like to see this project ! I did have a similar idea after making this but never found the time to actually work on it. The robot idea gives me the same vibes as the project that ottomated did, take a look at this video.
Do you host the Minecraft server on the same computer that runs the server for this repository? Or on a separate computer on the network? Or something else entirely?
So here's a quick overview of how it works : The user on the website connect to the web server and logs himself with his credentials. The web server ask a outside database to check the user information to allow the user to check his AE network if he has the correct password. This database runs a server somewhere hosted by Oracle, I just make requests to it. Then once the user is logged in, the server grabs the TCP socket that corresponds to the computer of the user then using this socket it uses a custom made communication protocol to ask the computer to send an updated view of the items in the network. The computer send the data over the socket and server display it to the user. So you don't need to have anything running on the same machine, the OpenComputer computers are each running on a different Minecraft server, maybe even using different modpacks. As the data is transmitted over a TCP socket your server/application can run anywhere. The main problem is that each computer need to initiate the TCP connection as it's impossible to make a TCP socket listen on the computer they can only connect to one, so the listening part is always on your server.
So why use TCP socket instead of the http requests ? The reason is that here the http requests are uni-directionnal, it will always be the computer asking the server, and the server giving some response. But it this case, and any application where reactivity is needed, the server needs to be the one notifiying the computer that an update is needed so once the socket connection has already been established you can do that, just have the computer wait for a new message on the socket and sent a corresponding response given the received message. Basically using sockets lets you have the computer waiting for some incoming commands which is not possible with http.
The complete flow for it to work is the following (given a new user that needs to create an account) :
- Launch server to listen for incoming TCP connections -> Using OC the user creates an account (username, password, a generated unique_id) -> OC makes a TCP connection to the server -> Sends on the socket the informations of the user -> The server checks this information (eg: not already existing user) and stores it in the databse -> Server sends a acknowledgement back to OC letting it know that the account creation was successful and closes the TCP connection -> OC write the user unique id on its hard drive.
If the user already has an account : First the OC computer needs to register its socket to the server :
-
Launch server to listen for incoming TCP connections -> Users launches the OC program -> OC makes a TCP connection to the server -> Read from the hard drive the user unique id and sends it on the socket -> Server gets the user id and stores the TCP socket in a table with the user id as a key.
Then wait for website user to ask for an update :
- Whenever a website user want to get updated data The server knows the user id of the user so it grabs the TCP socket corresponding to the user id -> Send on this socket a request for update -> OC computer wakes up because it got some new data on the socket -> Reads the request and know that it should send the current state of the network -> Computes the current state and sends it over the socket -> Server read this information and display it to the website user. The TCP connection should not be closed. Back to step 1
If you need more informations or something isn't clear, don't hesistate to ask,

I was wondering what your environment is for running this? I see that you also have a separate repository for the server side that uses flask. I am going to lay this out in different "sections" for ease of reading even if it might not help that much.... I am not really sure if this whole post is going to even look good of it's formatting.
I am sorry in advance for asking soo many questions at once and some of them might take some time to answer so sorry.... I am asking because I am working on a project that is very very similar however it's going to have a lot more capabilities than "just" managing a ME network. I wanted to test this project first to see what I can learn from it. I am probably not going to use a website but a desktop client made with Qt6 and python.

Thanks in advance again.
