Now that GNOME 42 was released in March I’ve had spare cycles to focus on porting Builder to GTK 4 in April. I’ve made a lot of progress thus far, but there is still plenty to go. Builder is certainly one of the larger GTK applications out there and so it can be a bit … Continue reading Builder GTK 4 Porting, Part I
During the past years (and especially last cycle) I’ve worked to push a number of features upstream from Builder into GtkSourceView. Not only does this improve the ecosystem for all applications, but it reduces the number of things we need to maintain downstream in Builder as we move to GTK 4. That included a new … Continue reading GtkSourceView Interactive Tooltips
Earlier this year I started a branch to track GTK 4 development which is targeted for release by end-of-year. I just merged it which means that our recently released gtksourceview-4-8 branch is going to be our LTS for GTK 3. As you might remember from the previous maintainer, GtkSourceView 4.x is the continuation of the … Continue reading GtkSourceView Next
Over the past few weeks I’ve been finishing up various projects for 3.36. None of this is surprising for those that follow me on twitter, but sadly I find it hard to blog as often as I should. One of the projects I completed before the end of the cycle is a memory allocation tracker … Continue reading Keeping your fast code fast
Sysprof has gained network and disk device statistics. You can use the combined graphs for a quick overview, or view them individually.
I back-ported the GTK 4 frame-profiler by Matthias to GTK 3 today. Here is an example of a JavaScript application using GJS and GTK 3. The data contains mixed native and JS stack-traces along with compositor frame information from gnome-shell. What is going on here is that we have binary streams (although usually captured into … Continue reading GTK 3 Frame Profiler
Years ago, when starting the Builder project, I added a real-time CPU graph so that it was easy to detect slow-downs quickly while hacking on the product. If I ever saw a main-loop stall, it would be immediately obvious. Over the years I added more advanced features like a Sysprof-based profiler. That duplicated the feature … Continue reading Removing my favorite feature
A decade ago I lived on the west side of Los Angeles. One of my favorite conferences was Southern California Linux Expo. Much like Karen, this is the conference where I performed my first technical talk. It’s also where I met and became friends with great people like Jono, Ted, Jeff, the fantastic organizing staff, … Continue reading Flatpak at SCaLE 15x
One of the great powers of namespace APIs on Linux (mount namespaces, user namespaces, etc) is that you can create a new view into the world of your computer that is very different from the host. This can make traditional profiling tools difficult. To begin with, we need to ensure that we have access to … Continue reading Profiling Flatpak’d applications
First off, I’ll be in Portland at the first ever LAS giving demos and starting on Builder features for 3.24. For a while now, you’ve been able to get Builder from the gnome-apps-nightly Flatpak repository. Until now, it had a few things that made it difficult to use. We care a whole lot about making … Continue reading Builder Nightly Flatpak
