Maintaining a libc is tough work, and we'd love some help!
## What to do
For now, we are still trying to get full libc compatibility before we move on to
any optimisation.
- We currently have a number of unimplemented functions. Search for
`unimplemented!()` and hop right in!
- If you notice any missing functionality, feel free to add it in
## Code style
We have a `rustfmt.toml` in the root directory of relibc. Please run `./fmt.sh`
before sending in any merge requests as it will automatically format your code.
With regards to general style:
### Where applicable, prefer using references to raw pointers
This is most obvious when looking at `stdio` functions. If raw pointers were
used instead of references, then the resulting code would be significantly
uglier. Instead try to check for pointer being valid with `pointer::as_ref()`
and `pointer::as_mut()` and then immediately use those references instead.
Internal functions should always take references.
### Use the c types exposed in our platform module instead of Rust's inbuilt integer types
This is so we can guarantee that everything works across platforms. While it is
generally accepted these days that an `int` has 32 bits (which matches against
an `i32`), some platforms have `int` as having 16 bits, and others have long as
being 32 bits instead of 64. If you use the types in platform, then we can
guarantee that your code will "just work" should we port relibc to a different
architecture.
### Use our internal functions
If you need to use a C string, don't reinvent the wheel. We have functions in
the platform module that convert C strings to Rust slices.
We also have structures that wrap files, wrap writable strings, and wrap various
other commonly used things that you should use instead of rolling your own.
## Sending merge requests
If you have sent us a merge request, first of all, thanks for taking your time
to help us!
The first thing to note is that we do most of our development on our
[GitLab server](https://gitlab.redox-os.org/redox-os/relibc), and as such it is
possible that none of the maintainers will see your merge request if it is
opened on GitHub.
In your merge request, please put in the description:
- What functions (if any) have been implemented or changed
- The rationale behind your merge request (e.g. why you thought this change was
required. If you are just implementing some functions, you can ignore this)
- Any issues that are related to the merge request
We have CI attached to our GitLab instance, so all merge requests are checked to
make sure that they are tested before they are merged. Please write tests for
the functions that you add/change and test locally on your own machine
***before*** submitting a merge request.
## Writing tests
Every function that gets written needs to have a test in C in order to make sure
it works as intended. Here are a few guidelines for writing good tests.
### Ensure that any literals you have are mapped to variables instead of being directly passed to a function.
Sometimes compilers take literals put into libc functions and run them
internally during compilation, which can cause some false positives. All tests
are compiled with `-fno-builtin`, which theoretically solves this issue, but
just in case, it'd be a good idea to map inputs to variables.
```c
#include "string.h"
#include "stdio.h"
int main(void) {
// Don't do this
printf("%d\n", strcspn("Hello", "Hi"));
// Do this
char *first = "Hello";
char *second = "Hi";
printf("%d\n", strcspn(first, second));
}
```
### Ensure your tests cover every section of code.
What happens if a string in `strcmp()` is shorter than the other string? What
happens if the first argument to `strcspn()` is longer than the second string?
In order to make sure that all functions work as expected, we ask that any tests
cover as much of the code that you have written as possible.
## Running tests
Running tests is an important part in trying to find bugs. Before opening a
merge request, we ask that you test on your own machine to make sure there are
no regressions.
You can run tests with `make test` in the root directory of relibc to compile
relibc, compile the tests and run them. This *will* print a lot of output to
stdout, so be warned!
You can test against verified correct output with `make verify` in the tests
directory. You will need to manually create the correct output and put it in the
tests/expected directory. Running any `make` commands in the tests directory
will ***not*** rebuild relibc, so you'll need to go back to the root directory
if you need to rebuild relibc.

# Redox C Library (relibc)
# RedBear-OS
relibc is a portable C standard library written in Rust and is under heavy development, this library contain the following items:
- C, Linux, BSD functions and extensions
- POSIX compatibility layer
- Interfaces for system components
The motivation for this project is twofold: Reduce issues that the Redox developers were having with [newlib](https://sourceware.org/newlib/), and create a more stable and safe alternative to C standard libraries written in C. It is mainly designed to be used under Redox, as an alternative to newlib, but it also supports Linux via the [sc](https://crates.io/crates/sc) crate.
Currently Redox and Linux are supported.
## `redox-rt`
`redox-rt` is a runtime library that provides much of the code that enables POSIX on Redox, like `fork`, `exec`, signal handling, etc.
Relibc uses it as backend in `src/platform/redox`, and it's intended to eventually be usable independently, without relibc.
## Repository Layout
- `include` - Header files (mostly macros and variadic functions `cbindgen` can't generate)
- `src` - Source files
- `src/c` - C code
- `src/crt0` - Runtime code
- `src/crti` - Runtime code
- `src/crtn` - Runtime code
- `src/header` - Header files implementation
- `src/header/*` - Each folder has a `cbindgen.toml` file, it generates a C-to-Rust interface and header files
- `src/ld_so` - Dynamic loader code
- `src/platform` - Platform-specific and common code
- `src/platform/redox` - Redox-specific code
- `src/platform/linux` - Linux-specific code
- `src/pthread` - pthread implementation
- `src/sync` - Synchronization primitives
- `tests` - C tests (each MR needs to give success in all of them)
## Download the sources
To download the relibc sources run the following command:
```sh
git clone --recursive https://gitlab.redox-os.org/redox-os/relibc
```
## Build Instructions
To build relibc out of the Redox build system, do the following steps:
### Dependencies
- Install `cbindgen`
```sh
cargo install cbindgen
```
#### Install the `expect` tool
- Debian, Ubuntu and PopOS:
```sh
sudo apt install expect
```
- Fedora:
```sh
sudo dnf install expect
```
- Arch Linux:
```sh
sudo pacman -S expect
```
### Build Relibc
To build the relibc library objects, run the following command:
```sh
make all
```
- Clean old library objects and tests
```sh
make clean
```
## Build relibc inside the Redox build system
Inside of your Redox build system, run:
```sh
make prefix
```
If you need to rebuild `relibc` for testing a Cookbook recipe, run:
```sh
touch relibc
make prefix r.recipe-name
```
Touching (changing the "last modified time" of) the `relibc` folder is needed to trigger recompilation for `make prefix`. Replace `recipe-name` with your desired recipe name.
Note: Do not edit `relibc` inside `prefix` folder! Do your work on `relibc` folder directly inside your Redox build system instead.
## Tests
Relibc has a test suite that also runs every time a new commit get pushed. You can see `.gitlab-ci.yml` to see how it's being executed. That being said, `./check.sh` is the recommended way to run tests. Here's few examples:
+ `./check.sh` - Run build, without running the test
+ `./check.sh --test` - Run all tests in x86_64 Redox using Redoxer
+ `./check.sh --test --host` - Run all tests in host (Linux)
+ `./check.sh --test --arch=aarch64` - Run all tests in specified arch
- Arch can be `x86_64`, `aarch64`, `i586`, or `riscv64gc`
+ `./check.sh --test=stdio/printf` - Run a single test
- Can be combined with `--host` or `--arch`
- Will run statically linked test in Linux, dynamically linked in Redox
Couple of notes:
- Relibc and its tests will rebuild if files changed, however switching between arch or host requires you to run `make clean`
- Redoxer is needed to run tests for Redox without `--host`. You can install it using `cargo install redoxer`
- Tests can hangs, the test runner can anticipate this, assuming the kernel doesn't hang too.
## Issues
#### I'm building for my own platform which I run, and am getting `x86_64-linux-gnu-ar: command not found` (or similar)
The Makefile expects GNU compiler tools prefixed with the platform specifier, as would be present when you installed a cross compiler. Since you are building for your own platform, some Linux distributions (like Manjaro) don't install/symlink the prefixed executables.
An easy fix would be to replace the corresponding lines in `config.mk`, e.g.
```diff
ifeq ($(TARGET),x86_64-unknown-linux-gnu)
- export CC=x86_64-linux-gnu-gcc
- export LD=x86_64-linux-gnu-ld
- export AR=x86_64-linux-gnu-ar
- export NM=x86_64-linux-gnu-nm
+ export CC=gcc
+ export LD=ld
+ export AR=ar
+ export NM=nm
export OBJCOPY=objcopy
export CPPFLAGS=
LD_SO_PATH=lib/ld64.so.1
endif
```

# dlmalloc-rs
A port of [dlmalloc] to Rust.
[Documentation](https://docs.rs/dlmalloc)
[dlmalloc]: https://gee.cs.oswego.edu/dl/html/malloc.html
## Why dlmalloc?
This crate is a port of [dlmalloc] to Rust, and doesn't rely on C. The primary
purpose of this crate is to serve as the default allocator for Rust on the
`wasm32-unknown-unknown` target. At the time this was written the wasm target
didn't support C code, so it was required to have a Rust-only solution.
This allocator is not the most performant by a longshot. It is primarily, I
think, intended for being easy to port and easy to learn. I didn't dive too deep
into the implementation when writing it, it's just a straight port of the C
version.
It's unlikely that Rust code needs to worry/interact with this allocator in
general. Most of the time you'll be manually switching to a different allocator
:)

#ifndef _SYS_QUEUE_H_
#define _SYS_QUEUE_H_
/*
* This file defines five types of data structures: singly-linked lists,
* lists, simple queues, tail queues, and circular queues.
*
* A singly-linked list is headed by a single forward pointer. The
* elements are singly linked for minimum space and pointer manipulation
* overhead at the expense of O(n) removal for arbitrary elements. New
* elements can be added to the list after an existing element or at the
* head of the list. Elements being removed from the head of the list
* should use the explicit macro for this purpose for optimum
* efficiency. A singly-linked list may only be traversed in the forward
* direction. Singly-linked lists are ideal for applications with large
* datasets and few or no removals or for implementing a LIFO queue.
*
* A list is headed by a single forward pointer (or an array of forward
* pointers for a hash table header). The elements are doubly linked
* so that an arbitrary element can be removed without a need to
* traverse the list. New elements can be added to the list before
* or after an existing element or at the head of the list. A list
* may only be traversed in the forward direction.
*
* A simple queue is headed by a pair of pointers, one the head of the
* list and the other to the tail of the list. The elements are singly
* linked to save space, so elements can only be removed from the
* head of the list. New elements can be added to the list after
* an existing element, at the head of the list, or at the end of the
* list. A simple queue may only be traversed in the forward direction.
*
* A tail queue is headed by a pair of pointers, one to the head of the
* list and the other to the tail of the list. The elements are doubly
* linked so that an arbitrary element can be removed without a need to
* traverse the list. New elements can be added to the list before or
* after an existing element, at the head of the list, or at the end of
* the list. A tail queue may be traversed in either direction.
*
* A circle queue is headed by a pair of pointers, one to the head of the
* list and the other to the tail of the list. The elements are doubly
* linked so that an arbitrary element can be removed without a need to
* traverse the list. New elements can be added to the list before or after
* an existing element, at the head of the list, or at the end of the list.
* A circle queue may be traversed in either direction, but has a more
* complex end of list detection.
*
* For details on the use of these macros, see the queue(3) manual page.

/*
* Include the definition of NULL only on NetBSD because sys/null.h

## OpenLibm
OpenLibm contains code that is covered by various licenses.
The OpenLibm code derives from the FreeBSD msun and OpenBSD libm
implementations, which in turn derives from FDLIBM 5.3. As a result, it
has a number of fixes and updates that have accumulated over the years
in msun, and also optimized assembly versions of many functions. These
improvements are provided under the BSD and ISC licenses. The msun
library also includes work placed under the public domain, which is
noted in the individual files. Further work on making a standalone
OpenLibm library from msun, as part of the Julia project is covered
under the MIT license. The test files, test-double.c and test-float.c
are under the LGPL.

# OpenLibm
[![codecov](https://codecov.io/gh/JuliaMath/openlibm/graph/badge.svg?token=eTAdN7d9cg)](https://codecov.io/gh/JuliaMath/openlibm)
[OpenLibm](https://openlibm.org/) is an effort to have a high quality, portable, standalone
C mathematical library ([`libm`](http://en.wikipedia.org/wiki/libm)).
It can be used standalone in applications and programming language
implementations.
The project was born out of a need to have a good `libm` for the
[Julia programming language](http://www.julialang.org) that worked
consistently across compilers and operating systems, and in 32-bit and
64-bit environments.
## Platform support
OpenLibm builds on Linux, macOS, Windows, FreeBSD, OpenBSD, NetBSD, and
DragonFly BSD. It builds with both GCC and clang. Although largely
tested and widely used on the x86 and x86-64 architectures, OpenLibm
also supports arm, aarch64, ppc64le, mips, wasm32, riscv, s390(x) and
loongarch64.
## Build instructions
### GNU Make
1. Use GNU Make to build OpenLibm. This is `make` on most systems, but `gmake` on BSDs.
2. Use `make USEGCC=1` to build with GCC. This is the default on
Linux and Windows.
3. Use `make USECLANG=1` to build with clang. This is the default on OS X, FreeBSD,
and OpenBSD.
4. Use `make ARCH=wasm32` to build the wasm32 library with clang.
5. Architectures are auto-detected. Use `make ARCH=i386` to force a
build for i386. Other supported architectures are i486, i586, and
i686. GCC 4.8 is the minimum requirement for correct codegen on
older 32-bit architectures.
**Cross Build**
Take `riscv64` as example:
1. install `qemu-riscv64-static`, `gcc-riscv64-linux-gnu`
2. Cross build:
```sh
ARCH=riscv64
TRIPLE=$ARCH-linux-gnu
make ARCH=$ARCH TOOLPREFIX=$TRIPLE- -j
make -C test ARCH=$ARCH TOOLPREFIX=$TRIPLE- -j
```
3. Run test with qemu:
```sh
qemu-$ARCH-static -L . -L /usr/$TRIPLE/ test/test-float
qemu-$ARCH-static -L . -L /usr/$TRIPLE/ test/test-double
```
### CMake
1. Create build directory with `mkdir build` and navigate into it with `cd build`.
2. Run CMake to configure project and generate native build system with `cmake /path/to/openlibm/`
or generate project with build system of choice e.g. `cmake /path/to/openlib/ -G "MinGW Makefiles"`.
3. Build with the build system with `cmake --build .`.
Default CMake configuration builds a shared library, this can easily be configured using
[BUILD_SHARED_LIBS](https://cmake.org/cmake/help/latest/variable/BUILD_SHARED_LIBS.html)
configuration option.
