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. Signed-off-by: Philip Withnall <pwithnall@endlessos.org> Fixes: #2329
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.

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.
