0.7.3 (2008-12-09) ======================== * Fixed compile error with new x86_64 code using GCC. 0.7.2 (2008-12-08) ======================== * Fixed major bug in printing child methods in graph reports. * Fixes for supporting x86_64 machines (Diego Pettenò) 0.7.1 (2008-11-28) ======================== * Added new AggregateCallInfo class for printers to make results easier to read. Take this call sequence for example: A B C | | | Z A A | | Z Z By default, ruby-prof will show that Z was called by 3 separate instances of A. In an IDE that is helpful but in a text report it is not since it makes the report much harder to read. As a result, printers now aggregate together callers (and children), matching ruby-prof's output from versions prior to 0.7.0. * Fixes for supporting x86_64 machines (Matt Sanford) 0.7.0 (2008-11-04) ======================== Features -------- * Added two new methods - RubyProf.resume and RubyProf.pause. RubyProf.resume takes an optional block, which ensures that RubyProf.pause is called. For example: 10.times do |i| RubyProf.resume do # Some long process end end result = RubyProf.stop * Added support for profiling tests that use Ruby's built-in unit test framework (ie, test derived from Test::Unit::TestCase). To enable profiling simply add the following line of code to your test class: include RubyProf::Test By default, profiling results are written to the current processes working directory. To change this, or other profiling options, simply modify the PROFILE_OPTIONS hash table as needed. * Used the new support for profiling test cases to revamp the way that Rails profiling works. For more information please refer to RubyProf's documentation. * Keep track of call stack for each method to enable more powerful profile visualizations in Integrated Development Environments (Hin Boean, work supported by CodeGear). * Expose measurements to Ruby (Jeremy Kemper). * Add support for additional memory measurements modes in Ruby 1.9 (Jeremy Kemper). * Add support for Lloyd Hilaiel's Ruby patch for measuring total heap size. See http://lloydforge.org/projects/ruby. (Jeremy Kemper). Fixes ------- * RubyProf.profile no longer crashes if an exception is thrown during a profiling run. * Measure memory in fractional kilobytes rather than rounding down (Jeremy Kemper) 0.6.0 (2008-02-03) ======================== ruby-prof 0.6.0 adds support for Ruby 1.9 and memory profiling. Features -------- * Added support for ruby 1.9 (Shugo Maeda) * Added support for outputting printer results to a String, Array or IO object (Michael Granger) * Add new memory profiling mode. Note this mode depends on a patched Ruby interpreter (Alexander Dymo) Fixes ------- * Improvements to GraphHtmlPrinter including updated documentation, fixes for min_time support, ability to specify templates using strings or filenames, and table layout fixes (Makoto Kuwata) * Fixes to scaling factor for calltrees so that precision is not lost due to the conversion to doubles (Sylvain Joyeux) * Changed constant ALLOCATED_OBJECTS to ALLOCATIONS in the C code to match the Ruby code (Sylvain Joyeux) * Added support for calltree printer to ruby-prof binary script (Sylvain Joyeux) * Fix support for the allocator measure mode to extconf.rb (Sylvain Joyeux) * Honor measure mode when specified on the command line (Sylvain Joyeux) * Sorting of methods by total time was incorrect (Dan Fitch, Charlie Savage) * Fix ruby-prof to work with the latest version of GEMS (Alexander Dymo) * Always define MEASURE_CPU_TIME and MEASURE_ALLOCATIONS in Ruby code, but set their values to nil if the functionality is not available. 0.5.2 (2007-07-19) ======================== ruby-prof 0.5.2 is a bug fix release. Fixes ------- * Include missing rails plugin 0.5.1 (2007-07-18) ======================== ruby-prof 0.5.1 is a bug fix and performance release. Performance -------- * Significantly reduced the number of thread lookups by caching the last executed thread. Fixes ------- * Properly escape method names in HTML reports * Fix use of -m and --min-percent command line switches * Default source file information to ruby_runtime#0 for c calls * Moved rails_plugin to top level so it is more obvious * Updated rails_plugin to write reports to the current Rails log directory * Added additional tests 0.5.0 (2007-07-09) ======================== Features -------- * Added support for timing multi-threaded applications * Added support for 64 bit systems (patch from Diego 'Flameeyes' Petten) * Added suport for outputting data in the format used by KCacheGrind (patch from Carl Shimer) * Add filename and line numbers to call tree information (patch from Carl Shimer) * Added Visual Studio 2005 project file. * Added replace-progname switch, als rcov. * Added better support for recursive methods * Added better support for profiling Rails applications Fixes ------- * Fixes bug when the type of an attached object (singleton) is inherited from T_OBJECT as opposed to being a T_OBJECT (identified by Francis Cianfrocca) * ruby-prof now works in IRB. * Fix sort order in reports. * Fixed rdoc compile error. * Fix tabs in erb template for graph html report on windows. 0.4.1 (2006-06-26) ======================== Features -------- * Added a RubyProf.running? method to indicate whether a profile is in progress. * Added tgz and zip archives to release Fixes ------- * Duplicate method names are now allowed * The documentation has been updated to show the correct API usage is RubyProf.stop not RubyProf.end 0.4.0 (2006-06-16) ======================== Features -------- * added support for call graphs * added support for printers. Currently there is a FlatPrinter, GraphPrinter and GraphHtmlPrinter. * added support for recursive methods * added Windows support * now packaged as a RubyGem Fixes ------- * Fixes bug where RubyProf would crash depending on the way it was invoked - for example, it did not run when used with Arachno Ruby's customized version of Ruby.
