One of the things I’ve done this cycle leading up to GNOME 45 is some rework on how we process *.syscap files. In particular, I wanted to really push the GListModel interface in GTK 4. That is a tall order at first sight because Sysprof capture files easily have hundreds of thousands of data frames. … Continue reading GListModel as a file format interface
I’m the author/maintainer of Sysprof. I took over maintainership from Søren Sandmann Pedersen years ago so we could integrate it with GNOME Builder. In the process we really expanded it’s use cases beyond just being a sampling profiler. It is a system-wide profiler that makes it very easy to see what is going on and … Continue reading Frame pointers and other practical near-term solutions
After about 5 months of keeping myself very busy, GNOME Builder 43 is out! This is the truly the largest release of Builder yet, with nearly every aspect of the application improved. It’s pretty neat to see all this come together after having spent the past couple years doing a lot more things outside of … Continue reading GNOME Builder 43.0
Previously Part IV, Part III, Part II, and Part I. Still working through medicine changes which have wreaked havoc on my sleep, but starting to settle in a bit more. Template-GLib Small changes here and there for template-glib to cover more cases for us in our keybindings effort. Improved type comparisons, fixed some embarrassing bugs, … Continue reading Builder GTK 4 Porting, Part V
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
