CHANGES - sys-cpu-0.7.2 Documentation

0.7.2 - 5-Sep-2015¶ ↑

Replaced a global array with a constant in the Linux version. Thanks go to Yorick Peterse for the patch.
Added method comments back to the Unix version.
Added a sys-cpu.rb stub file for your convenience.
This gem is now signed.

Added a workaround for a win32ole bug in the Windows version.
Reorganized code so that there is now a single gem rather than three separate platform gems.
Updated test-unit dependency which let me simplify the test files a bit.

Code base now uses FFI. However, HP-UX is not currently supported. HP-UX users should continue to use the 0.6.x version. Note that the code base remains unchanged on Linux and Windows.
The cpu_type method has been replaced with the architecture method on Solaris to keep the interface more in line with other platforms.
The type method has been changed to cpu_type on Windows.
Some Rakefile and test suite updates.

The CPU.freq method now works on OSX.
The CPU.model method on OSX has been altered. Previously it returned the machine model. However, the information is limited.
Fixed a couple unused variable warnings for the BSD/OSX code.
The Linux and Windows gems now have a 'universal' architecture.
Refactored the clean task in the Rakefile.

Fixed a bug in the install.rb file and refactored it a bit. Thanks go to Di-an Jan for the spot. Note, however, that this file will eventually be removed and/or integrated into the Linux source file.
Fixed the example Rake task, and refactored some of the other tasks.
Fixed and updated the CPU.architecture method on MS Windows to handle IA64 and x64 architectures.

Fixed a bug in the cpu_freq function (which would only be noticed on certain platforms in cases where the CPU.freq method failed). Thanks go to Edho P Arief for the spot.
Explicitly add sys/param.h on OpenBSD, and default to the HW_MODEL mib because HW_MACHINE does not exist. Thanks go to Edho P Arief for the patch.
Updated my support notes. In short I will support 1.8.6 and 1.9.x. I will not support any 1.8.x branch later than 1.8.6.
Removed redundant information in the various .txt files that is already covered in the README file.
Test files renamed.
Added test-unit 2.x as a development dependency.

Fix for OS X 10.5.x. Thanks go to Victor Costan for the spot and the patch.
Updated the gemspec and some other minor changes.
On MS Windows the impersonation level is now explicitly set to 'impersonate' to avoid issues where systems might be using an older version of WMI.

Added support for most BSD flavors, including OS X. The freebsd.c file is now just bsd.c.
The CPU.type method for Solaris has been changed to CPU.cpu_type to avoid conflicting with the Object.type method.
Added a Rakefile. There are now tasks for building, testing and installing, among other things. Run 'rake -T' to check your options.
Many internal directory layout changes - C source files are now under the 'ext' directory.
Improved RDoc comments in the C source files.
Changed CPUError to CPU::Error.

Fixed a bug in the Linux version where there could be a key but no

associated value, causing a String#strip! call to fail.  Now the value is
simply left at nil.

Refactored the CPU.processors method on Linux, including the removal of '?' from the CPUStruct members for the boolean methods (Ruby doesn't like them).
Minor tweaks and updates to the documentation, including the README.
Modified the gemspec so that it sets the platform properly for Linux and Windows.

Added a gemspec (and a gem on RubyForge).
The CPU.architecture method on HP-UX now returns nil if it cannot be determined instead of “Unknown” for consistency with the other platforms.
Inlined the RDoc and made some minor cosmetic source code changes.

Fixed in a bug in the Solaris version where CPU.load_avg returned bad values when compiled in 64 bit mode. Thanks go to James Hranicky for the spot and both James Hranicky and Peter Tribble (via comp.unix.solaris) for patches.
Made some modifications to the test suite. You know longer need to know which test suite to run. All platforms now use 'ts_all.rb', which will run the appropriate test case behind the scenes.

Bug fixed on Linux where empty lines could cause problems. This affected both the install.rb and linux.rb files, though it only seems to have been an issue on the 2.6+ kernel.
Altered the behavior of the CPU.cpu_stats method on Linux. Now, only the numbered cpu entries return associated data, unless the numberless entry is the only entry.
Added a sample program for Linux under the 'examples' directory.

Fixed a potential bug in the FreeBSD version of CPU.model.
Eliminated some warnings in the FreeBSD version.
Moved examples directory to the toplevel package directory.
Renamed and updated the sample scripts.
Added a sample script for FreeBSD.
Removed the INSTALL file. That information is now included in the README.
Made the CHANGES, README, and .txt files rdoc friendly.
The dynamic documentation generation for Linux has been altered. Anything relating to rd2 has been removed. The doc file generated is now doc/linux.txt.
Some $LOAD_PATH setup changes in the unit tests.

Now requires Ruby 1.8.0 or later.
FreeBSD support added.
Replaced 'CPUException' with 'CPUError'
The MS Windows version has been completely revamped to use WMI instead of the C API. Some method names have changed and some methods have been dropped entirely. Please see the documentation for details.
Corresponding documentation updates and test suite changes.
Sample programs have been moved to doc/examples.
Installation procedure somewhat revamped.
No longer autogenerates test file.
The .html files have been removed. You can generate the html on your own if you like.

Added MS Windows support
Changed some method names. The “cpu” has been dropped from most method names. See documentation for details.
The state() and freq() methods (where supported) now assume a default value of zero.
More unit tests added.
Fixed minor issue with test.rb for those without TestUnit installed.
Fixed issue with linux.rb file being auto-installed on non-Linux platforms.
Minor API change for the load_avg() method on HP-UX. It now accepts a CPU number as an argument.

Fixed a bug in the Solaris version that was using up and not freeing file descriptors.
Added html doc for Solaris under doc directory.
Minor changes to test_hpux.rb and test_sunos.rb
Minor README changes.

Added HP-UX support
Removed the VERSION class method. Use the constant instead
Changed license to “Artistic”
Moved version info into its own file for convenience
Some minor mods to the test suites
Modified extconf.rb, moving some of the dynamic test generation into separate files

Added the cpu_stats() class method for Linux, which contains the data from the 'cpu' lines of /proc/stat
Minor fix for extconf.rb (thanks Michael Granger)
Some tests added to Linux test suite
MANIFEST correction
