MooseFS 4.58.4: Cleaner Builds, Better Diagnostics
We’ve just released MooseFS 4.58.4 – a small maintenance update focused on build improvements, internal cleanup, and a few stability fixes. While most of the changes are under the hood, they help make the system more robust and easier to maintain going forward.
Build System Improvements
This release introduces Fedora .spec files, making it easier to build MooseFS packages on Fedora-based distributions. As part of this work, we made a minor adjustment to configure.ac and replaced autogen.sh with bootstrap.sh. This aligns the build process with what we’re planning for MooseFS 5.
Internal Cleanup
We’ve done some technical refactoring in the logging layer by introducing and standardizing the printflike macro in mfslog, along with fixing related syslog argument usage. This change does not affect users directly but improves code consistency and reliability.
We also silenced an unnecessary AddressSanitizer warning to keep build outputs cleaner and more useful.
Stability Fixes
A potential crash in masterresolver (Pro only) has been fixed. This issue could occur when using in an unofficial feature a list of IP addresses (instead of a hostname) if the list ended with an extra comma or semicolon. The parser now safely handles such cases.
Additionally, we added protection against multiple initializations of the strerr structure. This situation could happen in certain scenarios, such as repeated initialization of modules, and is now properly guarded.
Better Diagnostics
To improve troubleshooting, the master server now logs more detailed information when a chunk version mismatch occurs. Syslog messages include not only the current chunk version but also the version expected by the master, making it easier to identify and resolve inconsistencies.
MooseFS 4.58.4 is a small but solid step forward in improving reliability and maintainability. As always, we recommend upgrading to benefit from these fixes and improvements.
