7.74. graphviz
Updated graphviz packages that fix three bugs are now available for Red Hat Enterprise Linux 6.
Graphviz is open-source graph-visualization software. Graph visualization is a way of representing structural information as diagrams of abstract graphs and networks. It has important applications in networking, bioinformatics, software engineering, database and web design, machine learning, and in visual interfaces for other technical domains.
Bug Fixes
- BZ#772637
- Previously, the dot tool could generate different images on 32-bit and 64-bit architectures, which could consequently lead to multilib conflicts of packages that use graphviz during its build process. The problem was caused by different instructions used for floating points processing. On 32-bit Intel architecture, the code is now compiled with the "--ffloat-store" compiler flag, which ensures that identical images are generated regardless of the used architecture.
- BZ#821920
- The graphviz-tcl package included the "demo" directory, which contained examples in various languages. This caused implicit dependencies to be introduced. With this update, all examples are installed as documentation, which reduces the number of implicit dependencies.
- BZ#849134
- The "dot -c" command which is run in the %postun scriptlet recreates graphviz configuration files to be up-to-date with the current state of the installed plug-ins. Previously, if the command failed to load plug-ins specified in the configuration files, warning messages were printed when removing the graphviz-gd package. These messages could have been confusing, and have been therefore removed.
All users of graphviz are advised to upgrade to these updated packages, which fix these bugs.
