benchmarking - Rails 3.2.21 and Ruby 2.0 Performance Test Issues -


running rails performance test unsupported memory , objects in output. ruby 1.9x 1 can install gcdata patch. however, can't figure out how install ruby 2.0.

when run:

bundle exec rake test:benchmark rails_env=test

i get:

browsingtest#test_homepage (247 ms warmup)            wall_time: 3 ms               memory: unsupported              objects: unsupported              gc_runs: 0              gc_time: 0 ms  = 1.42 sfinished tests in 1.500688s, 0.6664 tests/s, 0.0000 assertions/s. 1 tests, 0 assertions, 0 failures, 0 errors, 0 skips

i have rails 3.2.21 , ruby 2.0:

ruby 2.0.0p598 (2014-11-13 revision 48408) [x86_64-darwin14.1.0]

the gcdata patch available latest version of 1.9.3. there no gcdata patch ruby >= 2.0.0. in opinion, have 2 options issue:

  1. keep branch of application running patched version of rails 1.9.3, , run tests there. downside results may not 100% accurate , if use ruby 2 syntax branch break.

  2. find way test memory usage , created objects, or don't use option @ new application. news ruby 2+ handles garbage collection better , should not run out of memory (unless interested number comparison app).

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
