`sysdeps/` is divded into per-port subdirectories. Exactly one of those subdirectories is enabled in each build.| -| `abis/` | OS-specific interface headers ("ABI headers"). Those contain the constants and structs of the OS interface. For example, the numerical values of `SEEK_SET` or `O_CREAT` live here, as well as structs like `struct stat`. ABI headers are _only_ allowed to contain constants, structs and unions but _no_ function declarations or logic.
`abis/` is divided into per-OS subdirectories but this division is for organizational purposes only. Ports can still mix headers from different `abis/` subdirectories.| - -## Porting mlibc to a new OS - -Ports to new OSes are welcome. To port mlibc to another OS, the following changes need to be made: -1. Add new `sysdeps/` subdirectory `sysdeps/some-new-os/` and a `meson.build` to compile it. Integreate `sysdeps/some-new-os/meson.build` into the toplevel `meson.build`. -2. Create ABI headers in `abis/some-new-os/`. Add symlinks in `sysdeps/some-new-os/include/abi-bits` to your ABI headers. Look at existing ports to figure out the ABI headers required for the options enabled by `sysdeps/some-new-os/meson.build`. -3. In `sysdeps/some-new-os/`, add code to implement (a subset of) the functions from `options/internal/include/mlibc/internal-sysdeps.hpp`. Which subset you need depends on the options that `sysdeps/some-new-os/meson.build` enables. - -We recommend that new ports do not build from `master` as we occasionally make internal changes that cause out-of-tree sysdeps to break. Instead we recommend you pin a specific release (or commit), or to upstream your changes to this repository so that we can build them on our CI and thus any breakages will be fixed by us in-tree. - -## Build Configuration - -The following custom meson options are accepted, in addition to the [built-in options](https://mesonbuild.com/Builtin-options.html). The options below are booleans which default to false (see `meson_options.txt`). - -- `headers_only`: Only install headers; don't build `libc.so` or `ld.so`. -- `mlibc_no_headers`: Don't install headers; only build `libc.so` and `ld.so`. -- `build_tests`: Build the test suite (see below). -- `disable_x_option`: Disable `x` component of mlibc functionality. See `meson_options.txt` for a full list of possible values for `x`. This may be used to e.g disable POSIX and glibc extensions. -- `linux_kernel_headers`: Allows for directing mlibc to installed linux headers. [These can be obtained easily](https://docs.kernel.org/kbuild/headers_install.html), placed in a directory and this option set to the corresponding path. This is required if the linux option is enabled, i.e. when the linux option is not disabled. - -The type of library to be built (static, shared, or both) is controlled by meson's `default_library` option. Passing `-Ddefault_library=static` effectively disables the dynamic linker. - -We also support building with `-Db_sanitize=undefined` to use UBSan inside mlibc. Note that this does not enable UBSan for external applications which link against `libc.so`, but it can be useful during development to detect internal bugs (e.g when adding new sysdeps). - -## Running Tests - -The `mlibc` test suite can be run under a Linux host. To do this, first run from the project root: -``` -meson -Dbuild_tests=true build -``` -This will create a `build` directory. Then, `cd build` and run the tests (showing output) with: -``` -meson test -v -``` diff --git a/lib/mlibc/RELEASE_PROCEDURE.md b/lib/mlibc/RELEASE_PROCEDURE.md deleted file mode 100644 index 6030205..0000000 --- a/lib/mlibc/RELEASE_PROCEDURE.md +++ /dev/null @@ -1,18 +0,0 @@ -# Versioning - -mlibc uses semantic versioning to denote releases. -A bump in the major version signals an ABI break. -A bump in the minor version signals a newly released set of features, while still maintaining ABI. -A bump in the patch signals a bug-fix, while not adding new features. - -# Release schedule - -A minor or major version will be released every two months (every even month).

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. - */ - -/* - * List definitions. - */ -#define LIST_HEAD(name, type) \ -struct name { \ - struct type *lh_first;
