Common
|
||||
------
|
||||
|
||||
* Add your name to [COPYING](/COPYING).
|
||||
* Don't add your name to `AUTHORS` - it's for maintainers.
|
||||
* Add copyright notice in the beginning of changed files except the headers.
|
||||
* If you change the behavior (even just fix a bug) of **libclayer** (stable),
|
||||
add a record to [ChangeLog](/ChangeLog).
|
||||
|
||||
Prohibitions:
|
||||
|
||||
* Don't commit binary files
|
||||
* Don't commit configuration files of your editor or IDE
|
||||
* Don't use encodings other than ASCII and UTF-8
|
||||
* Don't use alphabets other than Latin
|
||||
* Don't use languages other than English
|
||||
* Don't use tabulations (I don't hate tabs, but people can not use them
|
||||
properly)
|
||||
* Don't leave trailing whitespaces
|
||||
* Don't forget the newline character in the end of files
|
||||
|
||||
The following statements are recommendations, but highly encouraged:
|
||||
|
||||
* Write documentation
|
||||
* Write tests
|
||||
* Keep lines less than 80 characters long for better experience on split screen
|
||||
|
||||
### Things to review periodically
|
||||
|
||||
* `git grep -i fixme`
|
||||
* `git grep -i todo`
|
||||
* `git grep -i cppcheck-suppress`
|
||||
* `git grep -i rubocop:disable`
|
||||
|
||||
### Programming mistakes
|
||||
|
||||
* Always check documentation, manuals and specifications
|
||||
|
||||
Avoid stupid errors with:
|
||||
|
||||
* Manual memory management
|
||||
* `malloc` may return `NULL`
|
||||
* Memory leak (forget to `free`)
|
||||
* Use after `free`/`realloc`
|
||||
* Double `free`/`realloc`
|
||||
* `free`ing/`realloc`ating unallocated memory
|
||||
* Changing the original pointer to the allocated memory (use `const`!)
|
||||
* `NULL` pointers and `nil`/`None`/whatever objects
|
||||
* Division by zero
|
||||
* Pointer arithmetic - consider type size
|
||||
* Type sizes (like `long` on 32-bit and 64-bit)
|
||||
* Integer arithmetic overflow
|
||||
* Bit shift
|
||||
* Endianness (byte order)
|
||||
* Data packing
|
||||
* Data alignment
|
||||
* Thread safety
|
||||
* Undefined behavior
|
||||
* Logical expressions (tautology, whatever)
|
||||
* Checking for an error (return value, pointer argument, whatever)
|
||||
* Use of not fully initialized data
|
||||
* Not reading beyond a buffer, array or string
|
||||
* The index of the last item, which is less than the buffer size
|
||||
* Negative indices
|
||||
* The terminating null character in a string
|
||||
* Allowed values of arguments
|
||||
* Possible values of parameters
|
||||
* Operator precedence
|
||||
* Default case in switch statements
|
||||
* Braces (curly brackets) around code blocks
|
||||
|
||||
|
||||
|
||||
C language
|
||||
----------
|
||||
|
||||
Use **cppcheck**.
|
||||
|
||||
* Name regular functions (*not methods*) and variables in lower snake case
|
||||
(example: `foo_bar`).
|
||||
* Name macros in upper snake case (example: `FOO_BAR`).
|
||||
* Name types (*structures, unions, enumerations and type definitions*) in Pascal
|
||||
case (example: `FooBar`).
|
||||
* Name nested types in Pascal case and with the prefix of the surrounding type
|
||||
in Pascal case, separate type names with underscores (example:
|
||||
`FooBar_CarCdr`).
|
||||
* Name methods (*functions that belong to a specific type*) in lower snake case
|
||||
and with the prefix of the type name in Pascal case (example:
|
||||
`FooBar_car_cdr`).
|
||||
|
||||
* Use postfix `size` for a byte size.
|
||||
* Use postfix `slen` for C string length without terminating `\0` character
|
||||
(size - 1).
|
||||
* Use postfix `count` for a number of elements in an array.
|
||||
|
||||
* Create `typedef`s with the names of related `struct`s. Use this name with a
|
||||
prefix `struct` to declare the data itself, withoth the prefix to declare
|
||||
a pointer or an array:
|
||||
|
||||
```c
|
||||
typedef struct FooBar { int car; } *FooBar;
|
||||
|
||||
static struct FooBar FooBar_create();
|
||||
static void FooBar FooBar_init(FooBar foobar);
|
||||
|
||||
static void FooBar_do_something(FooBar foobar);
|
||||
|
||||
// Initialize:
|
||||
struct FooBar foobar = FooBar_create();
|
||||
// or
|
||||
struct FooBar foobar;
|
||||
FooBar_init(&foobar);
|
||||
|
||||
// Use:
|
||||
FooBar foobar_ptr = &foobar;
|
||||
FooBar_do_something(&foobar);
|
||||
```
|
||||
|
||||
```c
|
||||
typedef struct FooBar { int car; } FooBar[1];
|
||||
|
||||
static struct FooBar FooBar_create();
|
||||
static void FooBar FooBar_init(FooBar foobar);
|
||||
|
||||
static void FooBar_do_something(FooBar foobar);
|
||||
|
||||
// Initialize:
|
||||
FooBar foobar = { FooBar_create() };
|
||||
// or
|
||||
FooBar foobar;
|
||||
FooBar_init(foobar);
|
||||
|
||||
// Use:
|
||||
FooBar_do_something(foobar);
|
||||
```
|
||||
|
||||
* Mark variables and parameters with `const` if you don't plan to modify them
|
||||
* Only omit braces (curly brackets) of a block if it's statement is placed on
|
||||
the same line as conditional statement:
|
||||
|
||||
```c
|
||||
// Good:
|
||||
if (foo) return bar;
|
||||
if (foo) {
|
||||
return bar;
|
||||
}
|
||||
|
||||
// Bad:
|
||||
if (foo)
|
||||
return bar;
|
||||
```
