How can I update the pygobject recipe?

Application Development

I’m trying to update the recipe for pygobject. The version currently used is 3.50.0, but there are issues using element properties that are enums.

These MRs fix that and are in pygobject 3.53+.

Fix paramspec for enum and flags (!432) · Merge requests · GNOME / pygobject · GitLab

Add `_enum|flags_values_` back to GEnum and GFlags (!420) · Merge requests · GNOME / pygobject · GitLab

Also this issue I posted:

I tried to edit the pygobject.recipe file to use a different version, but the build failed.

class Recipe(recipe.Recipe):
name = ‘pygobject’
version = ‘3.54.2’
stype = SourceType.TARBALL
btype = BuildType.MESON
url = f’https://download.gnome.org/sources/pygobject/{version[0:4]}/pygobject-{version}.tar.gz’
url = ‘gnome://’
licenses = [{License.LGPLv2_1Plus: [‘COPYING’]}]

deps = ['pycairo', 'gobject-introspection', 'libffi']
tarball_checksum = '03cffeb49d8a1879b621d8f606ac904218019a0ae699b1cd3780a8ee611e696b'
meson_options = {
    'tests': False,
}

From the download page:

03cffeb49d8a1879b621d8f606ac904218019a0ae699b1cd3780a8ee611e696b  pygobject-3.54.2.tar.gz

The pygobject-fetch.log file has:

Downloading https://download.gnome.org/sources/pygobject/3.54/pygobject-3.54.2.tar.xz
Running command [‘powershell’, ‘-Command’, “Set-Variable -Name ProgressPreference -Value ‘SilentlyContinue’; Invoke-WebRequest -UserAgent GStreamerCerbero/1.26.7 -OutFile C:/Users/Tim/.cache/cerbero-sources/pygobject-3.54.2/pygobject-3.54.2.tar.xz -Method Get -Uri https://download.gnome.org/sources/pygobject/3.54/pygobject-3.54.2.tar.xz”\] in .
Invoke-WebRequest : 404 Not Found

Why is it looking for a file with extension “xz” when the recipe and download page has “gz”?

Recipe has two urls

url = f'https://download.gnome.org/sources/pygobject/{version[0:4]}/pygobject-{version}.tar.xz'
url = 'gnome://'

The first one is overwritten by the second one.

gnome:// is defined here:

    'gnome': ('https://download.gnome.org/sources/', '%(name)s/%(maj_ver)s/%(name)s-%(version)s', '.tar.xz'),

Where xz us hadcoded.

Simple solution is drop the second definition of url = 'gnome://' and keep only a explicit one:

class Recipe(recipe.Recipe):
    name = 'pygobject'
    version = '3.54.3'
    stype = SourceType.TARBALL
    btype = BuildType.MESON
    url = f'https://download.gnome.org/sources/pygobject/{version[0:4]}/pygobject-{version}.tar.gz'
    licenses = [{License.LGPLv2_1Plus: ['COPYING']}]

Thanks! That did it.

I guess my question now is: Why 2 urls? I can see that the second one would be a fallback URL if the first one was invalid or not available, but if the first one is good, why use the second one?

Looking at the template, the address is the same, it’s just that the extension in now invalid (obsolete?)

BTW, I needed to take out the patch, since it got merged in 3.53.0.

Looks like I do need that patch.

gi/__init__.py file changed enough that I need to find another patch, or edit the current one.

It’s a bug. Feel free to fix it. The Recipe is simply a Python class; having two URLs doesn’t mean anything.

Sure, you will need to update the patch because the MR is not merged yet :disappointed_face: .

How do you do that? I use git, but I’m not all that proficient in it.

In the web you can see the MR status is “open”.

I know. I commented on it, hoping to get some action on the pipeline.
