performancecounter - Apple Instruments - Counters - Source unavailable -


i've been running problem apple instruments (4.6, xcode 4.6.2 on 10.8.3). when using time profiler, can @ source , see hotspots without problems (same project).

this time i've been trying use "counters" template sample cpus performance counter events. samples events should , have same time based profiling information well, when try step code @ hot spots, can "time profiler", "unavailable" used have source. no assembly either.

the project built as:

  • release build
  • debugging information on , not stripped
  • dwarf + dsym used store profiling data.

as said, same configuration works time profiler. tried (pretty that's stated in here: xcode 4 instruments doesn't show source lines , except doing -o0, debug performance not of interest me)

  • recompile
  • relocate dysm file using "file -> re-symbolicate"

as plainly close instruments, start profile xcode , choose time profiler, works, if go performance counters, stops.

is default behaviour? should this? has managed working, in current instruments version? otherwise might worth file bug apple.

thanks lot!

try xcode 5.1 beta4. me fixed there: counter works now.

the seed notes mentions details did. don't know if under nda.

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers
