Re: Re: Re: Re: Process exists - Segmentation fault
Hi Gerald, Sorry for a late reply , no make test did not worked correctly, it did tested the modperl part and gave error like an error on line 21. I will try to give the exact error later, Thanks, Abhishek jain On 1/9/08, Gerald Richter - ECOS GmbH [EMAIL PROTECTED] wrote: Hi, Maybe we should go one step back: Does make test works correctly for you?

urgent help needed - this script does not chdir
Hi,
I am new to modperl and needs help, i have a script which works fine in
non-modperl enviornment but when i include in modperl::registry then mine
scripts when invoked via a browser finds itself in / directory i mean the
file or script do not include the files with the require command i mean the
relative path it cannot understand.
Additionally when i give this block,
BEGIN{
chdir('/home/absolute/directory');
};
then the script will run fine for some time and not fine i mean will give
error on including a function in a library included by require.
Pl. help me , i need a sol urgently ,
thanks ,

does begin block effect any performance in modperl
Hi friends,
i need to know that if i add the following block then will it affect
anything in the execution of modperl apart from first time run.
BEGIN{
require'abc.pl';
require'large_file.pl';
};
I mean anything relative to the performance.is the begin block called
everytime orjust the first time and is it safe to define a function in a
file and call it with this method rather than a package ,
Pl. help me.
Thanks,
Abhishek jain.
perlrun
Hi Friends,Actually i have a site written in PERL . I want that site to be working fast . Now i think modperl will make that fast. I know that the coding done is not that good, there are many global variables etc.I wanted to know that can modperl increase the speed without any risk to the site, A friend told me to use perlrun and not Apache:registry. Pl. tell me the difference between two.Also tell me that is there any coding style difference in mod_perl coding and normal cgi coding.Also by what ratio can modperl increase mine cgi applications speed.Pl. do answer .Thanks for your time and effort.--RegardsAbhishek jain Click here to donate to the Hurricane Katrina relief effort.
