Xdebug Update: October 2024
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.
On GitHub sponsors, I am currently 31% towards my $2,500 per month goal, which is set to allow continued maintenance of Xdebug. This is again less than last month.
If you are leading a team or company, then it is also possible to support Xdebug through a subscription.
In the last month, I spend around 10 hours on Xdebug, with 19 hours funded. I also spent 16 hours on the Native Path Mapping project.
PHP 8.4
I made the first beta release of Xdebug 3.4 that is compatible with PHP 8.4, which is due to be released on November 21st. I hope to have a GA release of Xdebug 3.4.0 out around that date too.
Beyond making that beta release, I have also looked into many bug reports, and fixed a few bugs.
As side-project to the new PIE installer, which is expected to replace PECL in the near future, a new Windows extension build action for GitHub actions has been created. I have been evaluating that, and provided some feedback. This is not quite ready for prime time, and I am not sure yet whether I will be able to use that for the 3.4 releases.
Native Xdebug Path Mapping
I also continued with the Native Xdebug Path Mapping project.
This is a separately funded project, I don't classify the hours that I worked on this in "Xdebug Hours". I also publish a separate report on the project page.
In short, I have finished the parser, and also made some performance improvements in the way I store data internally. I dive into the depths of that in its dedicated report.
I am now working on integrating it into Xdebug, and realised that there is one thing that I had forgotten to add, and that is a reverse mapping. The algorithms can only map remote a file/line to a local file/line, but in order to be able for an IDE to set a breakpoint on a local file line (which is how you would edit it), it also needs to have a reverse map.
By the end of this month I hope to have a working version to try out, but it will likely not be in the Xdebug 3.4 release, as that has to be released near when PHP 8.4 is released.
Xdebug Videos
I have created no new videos since last month, but you can see all the previous ones 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
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 mailinglist, which I will use to send out an update not more than once a month.
