No more Java in vscode-xml 0.15.0!

No more Java in vscode-xml 0.15.0!

Among other improvements and bug fixes in the vscode-xml extension 0.15.0 release, you can now run the extension without needing Java. We know the Java requirement discouraged many people from trying the extension. We have included a new setting, Prefer Binary (xml.server.preferBinary) that lets you choose between the Java server and the new binary server. We’re excited to remove the Java restriction from Red Hat’s XML extension for Visual Studio Code in vscode-xml 0.15.0. Keep reading to find out how we did it.

A guide to Red Hat OpenShift 4.5 installer-provisioned infrastructure on vSphere

A guide to Red Hat OpenShift 4.5 installer-provisioned infrastructure on vSphere

With Red Hat OpenShift 4, Red Hat completely re-architected how developers install, upgrade, and manage OpenShift to develop applications on Kubernetes. Under the hood, the installation process uses the OpenShift installer to automate container host provisioning using Red Hat Enterprise Linux (RHEL) CoreOS. It is then easy to initialize the cluster and set up the cloud domain name system (DNS), load balancer, storage, and so on.

Tips for writing portable assembler with GNU Assembler (GAS)

Tips for writing portable assembler with GNU Assembler (GAS)

Writing assembly code is straightforward when you are familiar with the targeted architecture’s instruction set, but what if you need to write the code for more than one architecture? For example, you might want to test whether a particular assembler feature is available, or generate an object file for use with another tool. Writing assembly source code that can work on multiple architectures is not so simple.

Debuginfod project update: New clients and metrics

Debuginfod project update: New clients and metrics

It’s been about a year since our last update about debuginfod, an HTTP file server that serves debugging resources to debugger-like tools. Since then, we’ve been busy integrating clients across a range of developer tools and improving the server’s available metrics. This article covers the features and improvements we’ve added to debuginfod since our last update.

How Red Hat ported OpenJDK to 64-bit Arm: A community history

How Red Hat ported OpenJDK to 64-bit Arm: A community history

It has been quite a year for Arm Ltd., the firm that designs reduced instruction set computing (RISC) architectures for computer processors. The news that Arm-based computers will be important for the foreseeable future has even reached the mainstream media. At the end of 2019, Amazon Web Services announced Arm-based Graviton2 servers. In June 2020, Apple announced its plans to move Macintosh computers over to Apple silicon—which means Arm.

Static analysis updates in GCC 11

Static analysis updates in GCC 11

The GNU logo.
I work at Red Hat on the GNU Compiler Collection (GCC). In GCC 10, I added the new -fanalyzer option, a static analysis pass for identifying various problems at compile-time, rather than at runtime. The initial implementation was aimed at early adopters, who found a few bugs, including a security vulnerability: CVE-2020-1967. Bernd Edlinger, who discovered the issue, had to wade through many false positives accompanying the real issue. Other users also managed to get the analyzer to crash on their code.

I’ve been rewriting the analyzer to address these issues in the next major release, GCC 11. In this article, I describe the steps I’m taking to reduce the number of false positives and make this static analysis tool more robust.
