Description

Announcing the GA release of Red Hat Enterprise Linux 9.0:

With Red Hat Enterprise Linux 9, you can:

Innovate - ships with GCC 11 (GNU Compiler Collection) and the latest versions of LLVM, Rust, and Go compilers, empowering developers to modernize their applications continually. Python 3.9 is included in Red Hat Enterprise Linux 9, bringing a faster release schedule, performance boosts, dictionary union operators, and more consistent and stable internal APIs.

Optimize - provides new Image Builder capabilities, including support for bare-metal deployments and customized file system settings to help organizations save time and ensure consistency when deploying and managing systems at scale. Red Hat Enterprise Linux 9 now offers Image Builder service to allow organizations to build a standardized and optimized operating system image through our hosted service and deploy it to your cloud provider of choice.

Protect - provides enhanced user authentication logs (via SSSD), web console support for smart card authentication with Sudo and SSH (Secure Shell client), disabled root login via SSH by default, and improved SELinux performance. Red Hat Enterprise Linux 9 also offers integrated OpenSSL 3 cryptographic framework, enhanced OpenSCAP profile, and integrity measurement architecture (IMA) digital hashes and signatures - to assist how organizations manage security and remain compliant when deploying new systems or managing existing infrastructures.

Trust - offers enhanced web console performance metrics, including Kernel live patching management through the web console, new System Roles for Postfix, Firewall, HA Cluster - to make it easier for organizations to automate manual tasks, standardize deployment at scale, and simplify day-to-day administration of systems. Red Hat Enterprise Linux 9 also offers improved scalability of Performance Co-Pilot (PCP) and Link Time Optimization (LTO) to help organizations identify, analyze and optimize the performance of their Red Hat Enterprise Linux systems with complete confidence.

Notes:

• There is no 'long integer' in Python 3 anymore.
• The long() function is no longer supported by Python 3. It only has one built-in integral type, named int()
• Octal literals are no longer of the form 0720- use 0o720 instead.
• The print statement has been replaced with a print() function, with keyword arguments to replace most of the special syntax of the old print statement (PEP 3105).
• Also, the dict.iterkeys(), dict.iteritems() and dict.itervalues() methods are no longer supported.
• The StringIO and cStringIO modules are gone. Instead, import the io module and use io.StringIO or io.BytesIO for text and data respectively.
• The builtin basestring abstract type was removed. Use str instead.
• In Python 3, use string.ascii_lowercase instead of string.lowercase.

Thank you, Alex.

Hello yujian,

I rebased the original patch (2.14.0-ddn53) and add only minimum syntax changes - required for py_compile.
But I'll continue to fix it - because I found a lot of issues related to Python2 -> Python3 migration.

Thank you very much!

I finally managed to reproduce on my test cluster the error seen with sanity-pcc test_21j on RHEL 9.0 client. It turns out this problem is due to the use of mrsh for pdsh rcmd module, instead of ssh, in the cfg file used to run auster (PDSH env variable).

So this problem is exactly the same as what we hit when we introduced CentOS/RHEL8, see LU-14443 and ATM-1962. I just opened ATM-2490 to tackle this issue on RHEL9.

[Sebastien Buisson]

As can be seen from test results at https://testing.whamcloud.com/test_sessions/03219e38-5c17-43c2-9e90-b34b1f642021, sanity-pcc test_21j is now passing on RHEL9.0 client.
