Simon McVittie 9f19eb454b docs: Soft-deprecate gsize in favour of standard size_t
We have chosen the underlying type that implements gsize to be the same
size as the standard C89 size_t (the top-level meson.build sets this up).

Unfortunately, we cannot guarantee that GLib and the C toolchain have
chosen the *same* fixed-size type: for example, on a typical ILP32
platform like 32-bit Windows or Linux, each of gsize and size_t
can either be int or long, while on a LP64 platform like 64-bit Linux,
each could either be long or long long. meson.build tries to choose the
same type to reduce compiler warnings, but it can only do this if the
compiler implements `-Werror`.

The in-memory representation is the same either way, but the choice of
underlying type matters when building printf format strings or issuing
compiler warnings, and can affect the C++ ABI of GLib-based software.
As a result, we can't just typedef gsize as size_t.

I've expanded the doc-comment to say a bit more about the implications
of the different types here, so that I can point to it from the
doc-comments of other types without repeating myself too much.

GLib

GLib is the low-level core library that forms the basis for projects such as GTK and GNOME. It provides data structure handling for C, portability wrappers, and interfaces for such runtime functionality as an event loop, threads, dynamic loading, and an object system.

The official download locations are: https://download.gnome.org/sources/glib

The official web site is: https://www.gtk.org/

Installation

See the file 'INSTALL.md'

Supported versions

Only the most recent unstable and stable release series are supported. All older versions are not supported upstream and may contain bugs, some of which may be exploitable security vulnerabilities.

See SECURITY.md for more details.

Documentation

API documentation is available online for GLib for the:

Discussion

If you have a question about how to use GLib, seek help on GNOMEs Discourse instance. Alternatively, ask a question on StackOverflow and tag it glib.

Reporting bugs

Bugs should be reported to the GNOME issue tracking system. You will need to create an account for yourself. You may also submit bugs by e-mail (without an account) by e-mailing incoming+gnome-glib-658-issue-@gitlab.gnome.org, but this will give you a degraded experience.

Bugs are for reporting problems in GLib itself, not for asking questions about how to use it. To ask questions, use one of our discussion forums.

In bug reports please include:

  • Information about your system. For instance:
    • What operating system and version
    • For Linux, what version of the C library
    • And anything else you think is relevant.
  • How to reproduce the bug.
    • If you can reproduce it with one of the test programs that are built in the tests/ subdirectory, that will be most convenient. Otherwise, please include a short test program that exhibits the behavior. As a last resort, you can also provide a pointer to a larger piece of software that can be downloaded.
  • If the bug was a crash, the exact text that was printed out when the crash occurred.
  • Further information such as stack traces may be useful, but is not necessary.

Contributing to GLib

Please follow the contribution guide to know how to start contributing to GLib.

Patches should be submitted as merge requests to gitlab.gnome.org. If the patch fixes an existing issue, please refer to the issue in your commit message with the following notation (for issue 123):

Closes: #123

Otherwise, create a new merge request that introduces the change. Filing a separate issue is not required.
