            What do curly braces in XAML actually mean?
            Asked 2022-Feb-04 at 05:19

            I'm a long-time C# programmer but I'm completely new to WPF and XAML. I can find plenty of tutorials that say "this is how to achieve this specific thing" but not "this is why you do this to achieve this specific thing". I'm seriously struggling to understand the meaning of various syntax in XAML.

            In this case, what do curly braces in attributes actually mean? What do they get translated to in terms of code? How do I reason about them? How do they get interpreted? Why does there seem to be multiple syntaxes (Binding="{Binding someProperty}" vs Binding="{Binding path=someProperty}")?

            I must be missing something obvious, but I've spent literally days reading tutorials, watching tutorials, even fighting my way through the immensely dry and difficult-to-understand Microsoft documentation and I still can't seem to figure it out.

            Let me try to illustrate where I'm getting stuck.

            This is part of the syntax of a XAML file, you can read all the gory details here

            Markup Extensions

            XAML defines a markup extension programming entity that enables an escape from the normal XAML processor handling of string attribute values or object elements, and defers the processing to a backing class. The character that identifies a markup extension to a XAML processor when using attribute syntax is the opening curly brace ({), followed by any character other than a closing curly brace (}). The first string following the opening curly brace must reference the class that provides the particular extension behavior, where the reference may omit the substring "Extension" if that substring is part of the true class name. Thereafter, a single space may appear, and then each succeeding character is used as input by the extension implementation, up until the closing curly brace is encountered.

            More information here

            Overview of markup extensions for XAML

            Also another good link tendered by @Charlieface

            Basic Markup Extension Syntax

            A markup extension can be implemented to provide values for properties in an attribute usage, properties in a property element usage, or both.

            When used to provide an attribute value, the syntax that distinguishes a markup extension sequence to a XAML processor is the presence of the opening and closing curly braces ({ and }). The type of markup extension is then identified by the string token immediately following the opening curly brace.

            When used in property element syntax, a markup extension is visually the same as any other element used to provide a property element value: a XAML element declaration that references the markup extension class as an element, enclosed within angle brackets (<>).

            react jsx inline style not rendering when populated from a variable
            Asked 2022-Jan-30 at 18:12

            I added an inline style element to a div tag in a react component along with a className element. The className property renders but the style is not displaying. I am setting from an object variable. However, if I set the style element directly using double curly braces it works, just not working from a variable.

            Here is an image of the object value I am using to set the style element.

            This shows where the style element should be getting set as the component is rendering, the styleElement object has a value set at this point

            This shows the component post rendering and the style element is not present

            What would prevent the style element from rendering even though is it populated from an object containing CSS properties?

            QUESTION

            Which are safe methods and practices for string formatting with user input in Python 3?
            Asked 2022-Jan-18 at 12:53
            My Understanding

            From various sources, I have come to the understanding that there are four main techniques of string formatting/interpolation in Python 3 (3.6+ for f-strings):

            1. Formatting with %, which is similar to C's printf
            2. The str.format() method
            3. Formatted string literals/f-strings
            4. Template strings from the standard library string module

            My knowledge of usage mainly comes from Python String Formatting Best Practices (source A):

            • str.format() was created as a better alternative to the %-style, so the latter is now obsolete
            • f-strings allow str.format()-like behavior only for string literals but are shorter to write and are actually somewhat-optimized syntactic sugar for concatenation
            • Template strings are safer than str.format() (demonstrated in the first source) and the other two methods (implied in the first source) when dealing with user input

            I understand that the aforementioned vulnerability in str.format() comes from the method being usable on any normal strings where the delimiting braces are part of the string data itself. Malicious user input containing brace-delimited replacement fields can be supplied to the method to access environment attributes. I believe this is unlike the other ways of formatting where the programmer is the only one that can supply variables to the pre-formatted string. For example, f-strings have similar syntax to str.format() but, because f-strings are literals and the inserted values are evaluated separately through concatenation-like behavior, they are not vulnerable to the same attack (source B). Both %-formatting and Template strings also seem to only be supplied variables for substitution by the programmer; the main difference pointed out is Template's more limited functionality.

            My Confusion

            I have seen a lot of emphasis on the vulnerability of str.format() which leaves me with questions of what I should be wary of when using the other techniques. Source A describes Template strings as the safest of the above methods "due to their reduced complexity":

            The more complex formatting mini-languages of the other string formatting techniques might introduce security vulnerabilities to your programs.

            1. Yes, it seems like f-strings are not vulnerable in the same way str.format() is, but are there known concerns about f-string security as is implied by source A? Is the concern more like risk mitigation for unknown exploits and unintended interactions?

            I am not familiar with C and I don't plan on using the clunkier %/printf-style formatting, but I have heard that C's printf had its own potential vulnerabilities. In addition, both sources A and B seem to imply a lack of security with this method. The top answer in Source B says,

            String formatting may be dangerous when a format string depends on untrusted data. So, when using str.format() or %-formatting, it's important to use static format strings, or to sanitize untrusted parts before applying the formatter function.

            1. Do %-style strings have known security concerns?
            2. Lastly, which methods should be used and how can user input-based attacks be prevented (e.g. filtering input with regex)?
              • More specifically, are Template strings really the safer option? and Can f-strings be used just as easily and safely while granting more functionality?
            ...

            ANSWER

            Answered 2022-Jan-18 at 12:53

            It doesn't matter which format you choose, any format and library can have its own downsides and vulnerabilities. The bigger questions you need to ask yourself is what is the risk factor and the scenario you are facing with, and what are you going to do about it. First ask yourself: will there be a scenario where a user or an external entity of some kind (for example - an external system) sends you a format string? If the answer is no, there is no risk. If the answer is yes, you need to see whether this is needed or not. If not - remove it to eliminate the risk. If you need it - you can perform whitelist-based input validation and exclude all format-specific special characters from the list of permitted characters, in order to eliminate the risk. For example, no format string can pass the ^[a-zA-Z0-9\s]*$ generic regular expression.

            So the bottom line is: it doesn't matter which format string type you use, what's really important is what do you do with it and how can you reduce and eliminate the risk of it being tampered.

            There's a special case that precludes D{{}}. It's a very particular set of conditions, so I imagine it's there specifically to prevent this exact recursion.

            [over.best.ics]/4 However, if the target is
            (4.1) — the first parameter of a constructor
            ...
            and the constructor ... is a candidate by
            ...
            (4.5) — the second phase of [over.match.list] when the initializer list has exactly one element that is itself an initializer list, and the target is the first parameter of a constructor of class X, and the conversion is to X or reference to cv X,
            user-defined conversion sequences are not considered.

            D{{}} is a list-initialization. D(D&&) constructor is considered by the second phase of it (the first phase looks at initializer-list constructors, like C(std::initializer_list) in your second example). But for it to be viable, there needs to be an implicit conversion from {} to D&&, and [over.best.ics]/4 suppresses it.

            These lines being well-formed relies on an aggregate deduction candidate, which provides a way for T to be deduced from aggregate intialization lists. This feature is indifferent to the syntax, so failing on either one but not the other is already inconsistent.

            In MSVC's case, it's the combination of class template parameter deduction and parenthesized aggregate intialization that is causing the issue (the latter works fine in isolation). MSVC also fails to compile A a(1);, which is more obviously well-formed.
