Simon McVittie 73c91ef799 Revert "glib-init: Add more static assertions for gintptr, guintptr" 
On closer inspection, these are redundant with stricter assertions that I
added in commit bd1e2a98 "glib-init: Statically assert more facts about
standard types", which assert that sizeof (gintptr) == sizeof (void *).

As far as I can tell, a sufficiently pedantic interpretation of Standard
C doesn't actually require (u)intptr_t to be the same size as a pointer:
it only requires that pointers can be losslessly stored in a (u)intptr_t,
which a sufficiently pathological ABI could implement by having (for
example) 32-bit pointers and a 64-bit uintptr_t just to troll us. However,
I'm fairly confident that no practically useful ABI would do this,
and certainly nobody has complained about this assertion since 2020.

Similarly, Standard C might permit an ABI where 64-bit pointers have the
first 32 bits always-zero and therefore storing the remaining bits in a
32-bit uintptr_t is lossless, but again, that would be pathological.

This reverts commit da3fc59544.

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 GNOME’s 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.
