Fourteen years later, it seems time for version 1.0! -Version 1.0 is a significant update that greatly improves the internals of ruby-prof and adds a number of improvements. - -Changes (Charlie Savage): - -* Profiling is significantly faster - 5x in some cases -* Recursive profiles are finally handled correctly. Yeah!!! -* Redesigned reports (Chirs Whitefield) -* New documentation website (https://ruby-prof.github.io) -* The ability to measure allocations and memory usage using a standard (unpatched) version of ruby -* The ability to save and reload profiling results for later analysis -* The ability track object allocations - -At the same time, it was also time to remove old code and deprecated methods. These changes include (Charlie Savage): - -* Drop support for old versions of ruby. Currently 2.4 and up are required. -* Remove support for method elimination (instead use method exclusion). -* Remove the CPU_TIME measurement mode since it duplicates the PROCESS_TIME mode and required inline assembly code -* Remove the GC_TIME and GC_RUNS measurement modes since they required patched ruby versions. In modern ruby it is possible to reimplement this functionality, but it does not seem of that much value (shout out if you want it back). -* Merge the RubyProf::FlatPrinterWithLineNumbers printer into RubyProf::FlatPrinter. -* Removed support for RUBY_PROF_EDITOR_URI environment variable that specified the link scheme. This features was more confusing then helpful. - - -0.18.0 (2019-05-27) -===================== -Fixes ------- -* Fix grouping by thread/fiber (Charlie Savage) -* Fix include/exclude thread checking (Charlie Savage) -* Fix failing tests (Charlie Savage) -* Fix grouping by thread_id and fiber_id (Charlie Savage) -* Update Visual Studio solution to 2019 (Charlie Savage) -* Adjust AbstractPrinter#editor_uri so it's possible to disable uri (Maciek Dubiński)- -* Fix -X/--exclude-file option not working (John Lindgren) -* Different directory for middleware output in readme (Aldric Giacomoni) -* Fixing spelling mistakes and typos (David Kennedy and Roger Pack) -* Add "allow_exceptions" option to Profile (Ryan Duryea) -* Update readme (Jan Piotrowski, Nathan Seither, victor-am) -* Travis updates (Niocals Leger and Charlie Savage) -* Fix NewRelic module detection in exclude_common_methods!

Ben Hughes, see https://github.com/ruby-prof/ruby-prof/pull/201). -* Methods can now be ignored during a profiling run instead of eliminating them - after a profile run, which has been deprecated (thx to Nelson Gauthier and Ben Hughes, - see https://github.com/ruby-prof/ruby-prof/pull/202). -* Use RUBY_PROF_EDITOR_URI=emacs to open source code links in the one true editor. - (thx Alexander Egorov, see https://github.com/ruby-prof/ruby-prof/pull/183 and - https://github.com/typester/emacs-handler). -* Fixed that calling profile.stop would stop profiling all active profiling runs. -* Fixed that remembering parent call frame pointer before stack reallocation could cause a segfault. -

- include_threads: an array of threads to include when collecting profile data - - merge_fibers: whether or not to merge the profile data for all fibers under their creating thread -* overhauled printer for cachegrind profiles: - - profile data for each thread dumped to a separate file, as kcachegrind does not - fully implement the cachegrind specification - - this required a change in interface: it's now necessary to specify a directory - where to dump the cachegrind files - - naming convention for cachegrind files changed so that kcachegrind shows them - all in the open dialog -* improved Rack middleware: - - it's now possible to use the MultiPrinter - - new option ignore_existing_threads: will ignore all prexisiting threads - when profiling a request, except the thread perfoming the request. - - new option request_thread_only: will ignore all preexisting threads, but also -

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.

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.

These changes include (Charlie Savage): + +* Drop support for old versions of ruby. Currently 2.4 and up are required. +* Remove support for method elimination (instead use method exclusion). +* Remove the CPU_TIME measurement mode since it duplicates the PROCESS_TIME mode and required inline assembly code +* Remove the GC_TIME and GC_RUNS measurement modes since they required patched ruby versions. In modern ruby it is possible to reimplement this functionality, but it does not seem of that much value (shout out if you want it back). +* Merge the RubyProf::FlatPrinterWithLineNumbers printer into RubyProf::FlatPrinter. +* Removed support for RUBY_PROF_EDITOR_URI environment variable that specified the link scheme.
