Is the backend Python and the frontend JavaScript? Because then that would happen and just be normal, because Boolean true is
Truein python.Probably, but if you're interpreting user inputs as raw code, you've got much much worse problems going on, lol.
[...]®ister=import os; os.system("sudo rm -rf /"); return TrueHey, that's my username too. Or it was going to be, while the site was still up.
What a coincidence!
I guess I'll wait for the site to come back, and see if it's still available...
It's the settiings file... It's probably supposed to only be written by the system admin.
A good place to put persistent malware. That's why when using docker images always mount as ro if at all possible.
It’s you can modify the settings file you sure as hell can put the malware anywhere you want
Every environment has plenty of good places to put persistent malware. Even if you run your docker images as ro.
Given the warning about capitalization, the best possible case is that they're using ast.literal_eval() rather than throwing untrusted input into
eval().Err, I guess they might be comparing strings to 'True' and are choosing to be really strict about capitalization for some reason.
Yeah. Maybe .to_lower() is really expensive in their environment, lol.
It's not User input, it's config file
I curse the sadist who decided True should be uppercase in Python
guido, why did you make python so weird?
In this instance, I think there was some suggestion to write code in mostly lower case, including all user variables, or at least inCamelCaseLikeThis with a leading lower case letter, and so to make True and False stand out, they've got to be capitalised.
I mean. They could have been TRUE and FALSE. Would that have been preferable? Or how about a slightly more Pythonic style: __true__ and __false__
i would go with lowercase and just have it be a reserved word like the other ones. but I'm not super picky, i generally like to stick to what people are used to, and i can understand the reasoning behind the choice.
Can't they just convert a "true" input to backend to uppercase
Yep they should use a config file format like JSON or TOML or YAML or what have you, and then decode that into python objects. Using an actual programming language for config is dumb as hell IMO. (inb4 pissed off suckless fans)
Depends on how it's set up. If the setting is going into the env it's a string, so I'd expect some sort of
Except maybe a little more elegant and not typed on my phone.
But if the instructions are telling the user to edit the settings directly, like where I wrote this_variable=True, they'd need to case it correctly there.
Fyi, using a condition to assign a boolean is equivalent to assigning the condition itself. No need for the IF.
true, though sometimes i find the more verbose style easier to read, and more maintainable (eg: you want to do something else in the block, you can just add a line instead of changing your ternary / etc). Small things
I refer you to #7 on Bruce Tognazzini's evergreen top ten list of design bugs.

Searching for the phrase, documentation matches for Taiga so maybe you're right!
