276832 - any graphical charts are not displayed correctly

Status: RESOLVED DUPLICATE of bug 275705

(Bugzilla :: Reporting/Charting, defect)

Description

[Thomas Leufkes]

in addition to bug#257497 ;-)

Our installation is 2.18rc2 under Red Hat Linux ES 3.0. 
Everything works fine but whenever a graphic should be displayed (old or new
graphs, pie, line and so on) it ends with a broken image. I fact the linked
png-files in the graphs-directory are empty (0 bytes). collectstats.pl runs
every night.

We had problems installaing the GD 1.x on our server under Red Hat. 
So we decided to install GD 2 (yes, with png support). 
But that should not be the problem.

Here is the output of my checksetup:

At the moment I wonder about how to test the graphs functionality in Bugzilla,
so I could figure out where is the problem ?

Any hints welcome !

Thomas: I'm not sure what to suggest. There is a bug where someone has attached
a patch for testing GD, but it's fairly self-evident that it doesn't work for
you. <sigh>. Your libgd and GD.pm versions should be compatible (assuming GD.pm
is using that version of libgd).

Could you try reinstalling GD.pm from CPAN?

I have installed the 2 png´s and 2 gif´s under t/ and added my testserver.pl
with the diff out of the patch. Here is the output:

[tst03:buggfi] /kmtools/bugzilla/gfi> testserver.pl http://bugtest.ihk-gfi.de/
TEST-OK Webserver is running under group id in $webservergroup.
TEST-OK Got ant picture.
TEST-OK Webserver is executing CGIs.
TEST-OK Webserver is preventing fetch of http://bugtest.ihk-gfi.de/localconfig.
Use of uninitialized value in print at ./testserver.pl line 148.
Use of uninitialized value in string eq at ./testserver.pl line 155.
TEST-FAILED GD Library generated a PNG that didn't match expected image.
  It has been saved as data/testgd-local.png
TEST-OK GD Library generated a good GIF image
TEST-FAILED Chart Library generated a png that didn't match expected image.
  It has been saved as data/testchart-local.png
[tst03:buggfi] /kmtools/bugzilla/gfi>


my line 148 is 
  print FH $my_png;
and line 155 is:
  if ($my_png eq $good_png) {


under data/ I can found a testgd-local.gif which seems to be ok.
testchart-local.png and testgd-local.gif are created empty (0 kb)
I can´t find testchart-local.gif.

just want to let you how we solve the problem:
- we installed GD Library 2.0 
- after that we compiled the Perl GD - Modul with -options PNG,JPEG,GIF -gd-path
/usr and then make test and install (without problems)
- after that the testserver.pl runs without errors:

[tst03:buggfi] /kmtools/bugzilla/gfi> testserver.pl http://bugtest.ihk-gfi.de
TEST-OK Webserver is running under group id in $webservergroup.
TEST-OK Got ant picture.
TEST-OK Webserver is executing CGIs.
TEST-OK Webserver is preventing fetch of http://bugtest.ihk-gfi.de/localconfig.
TEST-OK GD Library generated a good PNG image
TEST-OK GD Library generated a good GIF image
TEST-OK Chart Library generated a good png image
[tst03:buggfi] /kmtools/bugzilla/gfi>

Perhaps it is a good idea to let checksetup.pl look for the right GDlib version.

The GDlib 2.0 is not part of Red Hat ES 3.0. 
It´s seems to be included with RH ES 4.0.
