Philip Withnall 1ed67a9c44 gapplication: Expose zero-valued numbers in handle-local-options
This is a bit of a compromise. Since the option parsing in
`GApplication` is built on `GOptionContext`, there’s no way to
reliably indicate that a given option was passed by the user, other than
by its value changing. If the default value is zero, but the user
explicitly passed zero, nothing changes, so it’s not obvious that the
option was explicitly provided.

When just `GOptionContext` is being used, this is fine, as that’s
obvious what will happen from the way the API is built. With
`GApplication::handle-local-options`, though, the `GVariantDict`
provided by GLib to the callback claims to only contain the values of
the options provided by the user, and no defaults.

It’s not actually possible for GLib to do that reliably.

Previously, GLib was dropping all numeric values which were zero valued
(i.e. the defaults), as they *could* have been the defaults. It seems
like a slightly better behaviour to instead *not* drop those numeric
values, and err on the side of reporting some defaults as user-provided
(even if they weren’t) rather than dropping some user-provided values
which happen to be the defaults.

This adds a test for the case of parsing a double; the cases for
integers are analogous.

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.in'

How to report bugs

Bugs should be reported to the GNOME issue tracking system. (https://gitlab.gnome.org/GNOME/glib/issues/new). You will need to create an account for yourself.

In the bug report 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.

Patches

Patches should also 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.

Default branch renamed to main

The default development branch of GLib has been renamed to main. To update your local checkout, use:

git checkout master
git branch -m master main
git fetch
git branch --unset-upstream
git branch -u origin/main
git symbolic-ref refs/remotes/origin/HEAD refs/remotes/origin/main
