Webgrind + Rails

[krispouille]

Hello all,

Once again, congrats for this good app. I'm using webgrind for all my
php project and i don't have any BIG problems with it. Recently, i
switched to Rails and my idea was to keep webgrind as my default
profiler. For information, i've added "ruby-prof" in my gemfile
(http://ruby-prof.rubyforge.org/) and then i've followed the
instructions to have an output readable by Kcachegrind.

From now, i've succeeded in creating a list of all the calls BUT my
problems are :
- the "invocation count" column with the same value : 1
- the "total self cost" column with the same value : 0
- the "total inclusive cost" column with the same value : 0

In addition to that, my cachegrind.out... files for php and for ruby
seems to be similar; except may be the start :
my php cachegrind file starts with :
<code>
version: 0.9.6
cmd: Command line code
part: 1

events: Time
...
</code>

my ruby cachegrind file starts with :
<code>
events: Time
...
</code>

I hope this was to confusing for you ... Can you help me ?
Bye (sorry for my english)

HiSounds interesting. We have not tested with anything other than
cachegrind files generated by xdebug.
If you send me an example file I will have a look at it.

Hi,

Here are :

- the file (cachegrind.out.rails with only the first 100 lines ...) 

- my kcachegrind screenshot which seems to work well

- my webgrind screenshot (with the bug i've told you earlier)

Once again thx for your help.

It is unable to calculate percent of time because it uses the summary
line for that.

Try switching to milliseconds or microseconds. Does that work?

indeed ! it works ;-)

I have not tried it !

Great !

Great. It would be possible to change the code so that it uses the sum
of all invocations instead of the summary if it is not available.
