The GTK and WPE nightly bots at https://build.webkit.org/#/builders/30 and https://build.webkit.org/#/builders/2 run once per day generating a build-product for Ubuntu 20.04 Those products are uploaded to https://webkitgtk.org/built-products/x86_64/release/nightly/Ubuntu-20.04/MiniBrowser/ and https://wpewebkit.org/built-products/x86_64/release/nightly/Ubuntu-20.04/MiniBrowser/ The issue is that when you download one of those build-products and you execute "MiniBrowser --version" the version it outputs is from more than 6 months ago. Check: http://sprunge.us/CIKgiW - Version MiniBrowser_gtk_260526@main.zip is downloaded but when running `MiniBrowser --version` it outputs 252782@main Digging into this the problem is caused by how the script Tools/glib/apply-build-revision-to-files.py obtains the current version of WebKit. It uses origin/HEAD instead of HEAD and that causes a mistmatch with how the buildbot updates the git repository on the bots. See how buildbot updates the git repository: https://build.webkit.org/#/builders/30/builds/8422/steps/3/logs/stdio It basically does: git fetch -f - https://github.com/WebKit/WebKit.git HEAD --progress git reset --hard FETCH_HEAD -- instead of doing "git pull" or similar. So on the bot GTK-Linux-64bit-Release-Packaging-Nightly-Ubuntu2004 is currently happening this on the build checkout buildbot@bb-webkit-packaging-ubuntu2004-64:~/webkitgtk/nightly/GTK-Linux-64bit-Release-Packaging-Nightly-Ubuntu2004/build$ git status On branch main Your branch is ahead of 'origin/main' by 7808 commits.
