Xdebug Update: June 2025
In this monthly update I explain what happened with Xdebug development.
GitHub and Pro/Business supporters will get it earlier, around the first of each month.
In the last month, I spend around 22 hours on Xdebug, with 21 hours funded.
Xdebug 3.4
I spend most of the time this month working on bug fixes, resulting in the mid-month release of Xdebug 3.4.4. Most of the fixes revolved around exceptions and generating stack traces for them.
While fixing these, I also stumbled upon another bug. The issue here was that Xdebug wouldn't include the argument name for __invoke() call frames in its output. This only matters to PHP 8.1 and before though.
The rest of the month I spend on trying to resolve the code-coverage-with-fibers issue that I wrote about last month.
I now have a Pull Request that addresses the original bug and crash, but it does not yet fix all the problems that I discovered while running the test suite of reactphp/async with code coverage enabled. Therefore I did not manage to make another release this month addressing this issue. I hope to finalise this by the end of July.
Native Path Mapping
I have only played around with this during some demos in presentations showing this feature, but I did not make any progress with the feature itself.
It also seems that the PhpStorm team has not looked at my bug report either.
Xdebug Videos
I have created one new video in the last months:
All Xdebug videos can be watched on my channel.
If you have any suggestions, feel free to reach out to me on Mastodon or via email.
Business Supporter Scheme and Funding
On GitHub sponsors, I am currently 42% towards my $2,500 per month goal, which is set to allow continued maintenance of Xdebug.
If you are leading a team or company, then it is also possible to support Xdebug through a subscription.
In the last month, no new business supporters signed up.
Besides business support, I also maintain a Patreon page, a profile on GitHub sponsors, as well as an OpenCollective organisation.
If you want to contribute to specific projects, you can find those on the Projects page.
Xdebug Cloud
Xdebug Cloud is the Proxy As A Service platform to allow for debugging in more scenarios, where it is hard, or impossible, to have Xdebug make a connection to the IDE. It is continuing to operate as Beta release.
Packages start at £49/month, and I have recently introduced a package for larger companies. This has a larger initial set of tokens, and discounted extra tokens.
If you want to be kept up to date with Xdebug Cloud, please sign up to the mailing list, which I will use to send out an update not more than once a month.

@blog how do you track your time spent? Hoping to do something similar
@blog@sephster I have an Elgato Stream Deck on my desk, for which I have written some custom software:
https://github.com/derickr/streamdeck-goui/blob/master/README.rst
It allows me to configure buttons to press, for a specific "timer". I have one for Xdebug, PHP, random Open Source, and a few others.
Once I hit such a button, the timer start going, and when I hit it again, the timer stops and a dialog pops up on my desktop, in which I then can enter a description.

I have just released Xdebug 3.5.0!
In the next few weeks I will create some content (text, and perhaps video) highlighting some new features in more detail.
Please share it with the world!
