Help, Gruff is killing me

Rails
1

Hi all,

I hope somebody can help me out here, since the issue has been killing
me for the last three days. Here is the issue:

It seems that gruff kills rails/webrick whenever it’s used on win32. I
installed gruff per instructions and it seems to be working. The
sample controller generates a nice grpah with send_data and all. The
issue started once I try to use any other controller/template. Once a
gruff graph gets generated and sent to the browser any SUBSEQUENT
requests to other controllers fail with weird compile errors. For
instance:

Showing app/views/admin/show_management/list_shows.rhtml where line #5
raised:

compile error
./script/…/config/…/app/views/admin/show_management/list_shows.rhtml:5:
Invalid char `\001’ in expression
./script/…/config/…/app/views/admin/show_management/list_shows.rhtml:6:
parse error, unexpected $, expecting kEND
_erbout.concat "

Show ID\n"
^

Extracted source (around line #5):

A quick restart of webrick fixes the issue until I generate another
graph that is :frowning:

Thanks

Hi Rafeal,

One thing you might try is renaming mysql.so (do a search to find out
where
is it on your system) to see if it’s a driver issue. MySQL will pick
up
the native Ruby drivers if it can’t find the compiled version (which is
what
mysql.so is). There’s a known issue with the compiled version and
WEBrick
that’s currently under investigation. Changing drivers might not help,
but
it’s cheap to try :wink:

Best regards,
Bill

Hello Rafael,

Showing app/views/admin/show_management/list_shows.rhtml where line #5 raised:

compile error
./script/…/config/…/app/views/admin/show_management/list_shows.rhtml:5:
Invalid char `\001’ in expression
./script/…/config/…/app/views/admin/show_management/list_shows.rhtml:6:
parse error, unexpected $, expecting kEND
_erbout.concat "

Show ID\n"

Try to check whether it’s a tabulation pb.
Suppress (or replace with spaces) any tabs in your list_shows.rhtml
file.

Yup that expecting kEND error on windows is a know issue. If you

have any tab chars in your view files they will cause this error.
Make sure to only use spaces and you will be fine.

Is Gruff using RMagick and you use ruby 1.8.4 under windows ? If that is
the
case, then that is the reason for your problems …

yes, use minimagick (might require quite a lot of customization for
gruff).
If you do it, plese post it

7

yep, Ruby 1.8.4 + Rmagick installed from local gem
(RMagick-win32-1.9.2-mswin32.gem)

I did some digging since the email, and it looks like it’s Rmagick
issue. For instance in IRB require ‘rmagick’ errors out with:
undefined method assoc' for classMagick::ImageList’

and require_gem ‘rmagick’ complains about not being able to find the
gem.

Any known resolutions to this issue?
