If you want to make C a safer language, one obvious thing is to disallow
using “=” in the middle of an expression. Instead of returning the value
of the expression, have it return void. Or just disallow it syntactically
altogether.
Sure, you may still want to write something like
a = b = c;
but Python has found a way to allow that, without saying that “b = c” has
to return a value.

Python's original solution is stupid. All they had to do is to use := for assignment, and leave = as a comparison. ... and that's what they did now, as of Python 3.8. There is a := assignment that can be used in the middle of an expression. This is given the idiotic nickname "walrus operator". := can be used in the middle of expressions. Except they can't drop the old = assignment due to backward compatibility. Walrus is what should have been assignment in the first place. But because Van Possum was coding Python in C, he just aped some C choices into the language. (I'm guessing that he knew that the first people to get their hands on Python and popularize it would be C-and-Unix people, who would balk at a := operator.) By the way, assignment in the middle of expressions comes from Lisp. Basically the idea that everything is an expression, even things that perform side effects or behave like statements. The ternary operator comes from Lisp: (if expr then else). [CLISP] [1]> (let ((i 0)) (list (incf i) (incf i) (incf i))) (1 2 3) You're unlikely to type setf or incf when you wanted a comparison. ANSI Common Lisp is strictly evaluated so the above is required to produce (1 2 3) and not (2 1 3) or whatever. Stuffing side effects into Lisp expressions is less risky than in C. (Not so with Scheme: in Scheme, the evaluation order of function arguemnts is unspecified, like in C!) -- TXR Programming Language: http://nongnu.org/txr Cygnal: Cygwin Native Application Library: http://kylheku.com/cygnal Mastodon: @Kazinator@mstdn.ca

But I don't think it is remotely feasible to change this in C - you are fifty years too late. The nearest you can come to changes like this in C would be optional warnings or checks in compilers and static analysers.

There must be some paper describing bugs "in the wild"* and categorising them by what language features would have made them either impossible or less likely.

User Can you list C language bugs, categorising them by what language features would have made them either impossible or less likely. ChatGPT Certainly! Here are some common bugs in C categorized by language features that could have prevented them or made them less likely: Null Pointer Dereference: Language Feature: Safe pointer handling like in Rust or smart pointers in C++. Features like optional nullability annotations or language constructs that enforce non-null pointers can help prevent null pointer dereference bugs. Buffer Overflows: Language Feature: Bounds checking in arrays. Languages like Rust have built-in checks to prevent buffer overflows at compile-time. Safe string handling functions like those provided by libraries such as Safe C String Library (SCL) or SafeLib. Memory Leaks: Language Feature: Automatic memory management like garbage collection or smart pointers. Languages like Java, C#, and modern C++ with RAII (Resource Acquisition Is Initialization) significantly reduce the occurrence of memory leaks. Use After Free: Language Feature: Automated memory management, such as garbage collection, or ownership tracking systems like those found in Rust's ownership model. Uninitialized Variables: Language Feature: Initialization guarantees or compiler warnings for uninitialized variables. Tools like static code analyzers or compilers with strong type checking can help detect such issues. Type Safety Violations: Language Feature: Strong static typing. Languages like Java, C#, or Rust enforce stronger type safety, reducing the likelihood of type-related bugs. Race Conditions: Language Feature: Built-in support for concurrent programming paradigms, such as message passing (e.g., Erlang) or ownership model (e.g., Rust), or immutability (e.g., functional programming languages like Haskell). Integer Overflows: Language Feature: Safe arithmetic operations. Languages like Rust provide safe arithmetic operations that panic on overflow, preventing undefined behavior. Resource Management Issues (e.g., File Handles, Sockets): Language Feature: RAII (Resource Acquisition Is Initialization) or using constructs like "defer" in Go. Languages like Rust with its ownership model can enforce proper resource management. Unprotected Access to Shared Resources: Language Feature: Mechanisms for synchronization and concurrent access control, such as locks, semaphores, or higher-level constructs like channels in Go or message passing in Erlang. Floating Point Precision Errors: Language Feature: Enhanced floating-point arithmetic support or arbitrary-precision arithmetic libraries. Languages like Python or libraries like GNU MPFR provide arbitrary-precision arithmetic, reducing precision errors. Pointer Arithmetic Errors: Language Feature: Restricted or controlled pointer arithmetic. Safe pointer operations and bounds checking can prevent pointer arithmetic errors. By incorporating these language features or using languages with built-in protections against common programming errors, developers can significantly reduce the likelihood of encountering these bugs.

Yes, it's a good summary of what passes for "common knowledge". But I was talking about something else altogether -- actual bugs found in real code, maybe taken from an analysis of security advisories. How many can (to take one example) be attributed, in whole or in part, for using assignment in a larger expression? -- Ben.

I think it is very difficult to get good statistics on this kind of thing. You can't really do a controlled study comparing one group programming in "C where assignment is an expression" with a group programming in "C where assignment is a statement". And you certainly can't do a double-blind placebo controlled test! There are plenty of coding standards which ban the use of the results of assignment expressions, and I think there is little doubt that stricter coding standards reduce at least some kinds of errors in code. But it would be impossible to isolate the effect of one particular rule. If someone knows about such studies, it would be great to hear about them - failing that, guesses and gut feelings based on personal experience is about as good as we can get. > > * I mean to exclude bugs that get found early.

However, I /have/ seen such bugs in code that has been written and deployed, precisely because even the most crude tests and static checking where not employed. Far and away the biggest steps towards "safe C" is for people to use good development practices, including good testing, good static error checking, appropriate training, code reviews, etc. The unfortunate reality is that there are many programmers who don't use such practices, or don't use them correctly. And I don't think a change to how assignment works would make a noticeable difference to this much larger and more general problem.

In the contexts I was working I never experienced (own or others') real problems with cascading assignments. The only problems arose with the if-assignment cases; to detect these errors at that time time was lost (unnecessarily). (A price we had to pay when using C/C++.) Janis

It was probably Lisp that introduced the idea of assignment being an expression (due to everything being an expression). It's a safe language, and not less safe on that account. This is because you are vanishingly unlikely to accidentally write (setq a b) when you intended (eq a b), and if that were to happen, another pair of reviewing eyes would likely not gloss over it. Python has now reintroduced a form of assignment you can use in the middle of an expression; the token is := which is unlikely to be used by mistake instead of an equality test or whatnot. -- TXR Programming Language: http://nongnu.org/txr Cygnal: Cygwin Native Application Library: http://kylheku.com/cygnal Mastodon: @Kazinator@mstdn.ca

I suggest that the bug of using "=" where "==" was intended occurs
almost exclusively among inexperienced C programmers, particularly those
who are inexperienced with programming in general.
It's a mistake that's made because the programmer assumes that "="
is a comparison operator, as it is in mathematics and in some other
programming languages. It's an easy and understandable mistake
to make, but any reasonably experienced C programmer will have
internalized the fact that "=" means assignment, not comparison.
To a newbie, `if (x = y)` *looks like* a comparison. To an
experienced C programmer it doesn't.
(It's possible I'm overgeneralizing. For example, a programmer who
commonly switches between C and other languages might still mix up "="
and "==" occasionally.)
If C had used ":=" for assignment and "=" for comparison (and "=="
probably not used for anything), the problem would never have come up,
because ":=" doesn't look like a comparison even to a newbie. But it's
far too late to fix that in any language called "C".
