Spent some time in the lab today trying to reproduce and I was unable to.
Here are some of the important packages in the lab setup:
Installed Packages
mod_perl.i386 2.0.4-6.el5
perl-SOAP-Lite.noarch 0.711-1.el5.rf
Available Packages
perl-LWP-UserAgent-Determined.noarch 1.04-1.el5.rf

Problem experienced on another server. Maybe I didn't experience it in the lab because the mod_perl config was not correct (IOW not running under mod_perl)?

Getting rid of latest soap: `rpm -e --nodeps perl-SOAP-Lite`
and re-installing an older version: `yum install perl-SOAP-Lite-0.710.08` fixed it. |
|
|
|
|
|
a new version is out but it's not packaged yet |
|
|
|
|
upgrading from SOAP 0.710.08 to 0.711 pulls in:
perl-FCGI-0.68-1.el5.rf.i386.rpm
perl-XML-Parser-2.36-1.el5.rf.i386.rpm
and I was able to reproduce the problem by changing the server-side lib only:
Client - Application failed during request deserialization:
no element found at line 1, column 0, byte -1 at /usr/lib/perl5/vendor_perl/5.8.8/i386-linux-thread-multi/XML/Parser.pm line 187 |
|
|
|
|
|
The print statement in pf::node::node_modify is also responsible here.. See 0001068 for details. |
|
|
|
|
built perl-SOAP-Lite-0.712-1, installed it and it didn't resolve the issue, still failing with:
no element found at line 1, column 0, byte -1 at /usr/lib/perl5/vendor_perl/5.8.8/i386-linux-thread-multi/XML/Parser.pm
line 187
built perl-XML-Parser same problem..
After a lot of trial and errors + googling, finally found an open ticket for the problem:
https://rt.cpan.org/Public/Bug/Display.html?id=58538 [^]
It is an upstream bug in the CGI handler when used by mod_perl... :( |

I ported cgi-bin/pdp.cgi SOAP CGI handler to use full blown mod_perl SOAP-Lite hosted code. That fixes the issue.
However, I detect performance regression since our last tests (not sure if its the fix since last tests were long time ago..).
I'll need to investigate a little bit more before commit.

Fixed, see previous comment for details.
Performance problem turned out to be a constraint of our lab system which doesn't have enough RAM to run all the apache thread with mod_perl. Once tweaked, the performance numbers were up to our expectations. |
