"use lib" statements in startup.pl

I saw this, and added a "use lib" line to my startup.pl (the second
one, below). I am receiving an error, and the error does not include
either of the "use lib" directories below in @INC. Here is my
startup.pl:
#!/usr/local/bin/perl
BEGIN {
use Apache ();
use lib Apache->server_root_relative('lib/perl');
use lib "/usr/local/share/apache/cgi-bin/common";
}
use Apache::Registry ();
use Apache::Constants();
use CGI qw(-compile :all);
use CGI::Carp ();
# Other common modules
use LWP ();
require "cgi-jdm/hashdata.pl";
1;
Here is the error when I try to use my script. The script has
require "foolib.pl";
require "foolib2.pl";
at the top of it. Both libraries exist in the "common" directory
listed in the startup.pl script.
The error is:
Can't locate foolib.pl in @INC (@INC contains:
/usr/local/lib/perl5/5.00503/aix /usr/local/lib/perl5/5.00503
/usr/local/lib/perl5/site_perl/5.005/aix
/usr/local/lib/perl5/site_perl/5.005 .) at insert.pl line 3
As you can see, @INC does not contain either of the directories.
AIX 4.3.3, Apache 1.3.11, mod_perl 1.21
Any help greatly appreciated.

When Apache isn't already running, it sends the output from startup.pl
etc. for STDERR to the terminal that is trying to start it. That's
because the configuration files haven't been completely parsed at this
point and Apache doesn't know whether or not they're broken. If it's
already running, it sends the output to the error_log instead because
it knows its current configuration is OK - but it doesn't know about
the (possibly new and exciting) configuration it's reading. If you
think about it for long enough it makes sense. You're just sending
different signals to httpd through apachectl, some of which (e.g.
`apachectl graceful') will not stop Apache, if it's already running.
Then I found it best to stop thinking about it, and do something else.
How are you getting on?

Re: "use lib" statements in startup.pl
Posted by jm...@vipcompute.com.
Back again. As always, I appreciate the help.
I did some further debuigging. In the startup.pl, I put in a loop that
prints out all of the directories in @INC at the end of the BEGIN
block. Here is the output from that.
Running startup.pl
@INC contains:
/usr/local/share/apache/cgi-bin/common
/usr/local/share/apache/lib/perl
/usr/local/lib/perl5/5.00503/aix
/usr/local/lib/perl5/5.00503
/usr/local/lib/perl5/site_perl/5.005/aix
/usr/local/lib/perl5/site_perl/5.005
.
/usr/local/share/apache/
/usr/local/share/apache/lib/perl
apachectl start: httpd started
This looks fine (the top two are the directories I am trying to add to
@INC, but when I try to run my script, I get the same error (look
closely at @INC in this error - the two additional directories are not
there!):
Can't locate foolib.pl in @INC (@INC contains:
/usr/local/lib/perl5/5.00503/aix /usr/local/lib/perl5/5.0
0503 /usr/local/lib/perl5/site_perl/5.005/aix
/usr/local/lib/perl5/site_perl/5.005 .) at insert.pl line 3

About to do this.

Yes - the above output from startup.pl, plus
[notice] Apache/1.3.11 (Unix) mod_perl/1.21 configured -- resuming
normal operations

They seem to be made when I thought they were.
Again, thanks for any help and direction. I am off to see what I can
find in the Guide.

Nope, looks like it was (3) after all.
I just tried it on my server and it comes out on the terminal here too.
It seems your Apache is running startup.pl OK.
Er, **sorry** if I confused you with this screwup.

I guess this was just a typo?

Same answer, more or less. Find out what's in @INC after your
"use lib" statements (e.g. more print statements in BEGIN blocks,
stuff like that). Read the Guide about what happens to @INC under
Apache/mod_perl.
Have you got any more info?
You haven't got another copy of httpd running as well, have you?
Are you getting anything written in your error_logs now?
Have you checked the dates and times in the log entries to make sure
that they were made when you think they were made?

It means that either
(1) the Apache parent didn't execute startup.pl, something else did
or
(2) you didn't do what I wanted you to do
or
(3) I don't have the faintest idea what's going on.
My guess is (1).
> Where do I go next?
More debugging. Find out what's executing startup.pl and why it's not
httpd. You *have* got a mod_perl server running? What does `httpd
-l' say? Find out what's in @INC after your "use lib" statements
(e.g. more print statements in BEGIN blocks, stuff like that).
Read the Guide about what happens to @INC under Apache/mod_perl.

Like I said, the surprise would have been if it was in your error_log:)
I'm going to hit the sack now, it's gone midnight here.

Re: "use lib" statements in startup.pl

Well, I did not see the message in my error_log, but I DID see it at
the command line:
/usr/local/share/apache/bin> # apachectl stop
apachectl stop: httpd stopped
/usr/local/share/apache/bin> # apachectl start
Running startup.pl
cd apachectl start: httpd started
What does this mean?
Where do I go next?
Thanks for any help - sorry to surprise you.

If you're using recent versions of Apache::AuthCookie, then you *are* going to
change ->authen and ->authz to ->authenticate and ->authorize, right? =)
The next version of AuthCookie, which I'm working on now, will have these
deprecated methods removed.

Why 'require' required?
Posted by Jie Gao <J....@isu.usyd.edu.au>.
Hi All,
I have this in my .htaccess file:
PerlSetupEnv On
PerlSetEnv SYBASE /usr/local/open_client
PerlSetEnv DBI_DRIVER Sybase
PerlAuthenHandler my::AuthCookieHandler->authen
PerlAuthzHandler my::AuthCookieHandler->authz
AuthType my_domain
AuthName Authen
PerlSetVar AuthenLoginPageLocation 'https://xxx.ucc.usyd.edu.au/perl-bin/login.cgi'
PerlSetVar DSName mydb
PerlSetVar DSF /usr/local/open_client/dbconf
PerlSetVar VirtualServerName xxx.ucc.usyd.edu.au
PerlSetVar TimeOut 50000
PerlSetVar CourseAllowed "pcol2001 pcol2002"
PerlSetVar EnrolCkDSName SYB_FLX_TRAIN
require valid-user
PerlSetVar AuthCookieDebug 6
Now if I comment out "require valid-user", neither of the
PerlAuthenHandler and PerlAuthzHandler will be evoked, even though it
is a phoney requirement for my handler; if I put in one require
statement, like 'require authentication', it'll start working again.
Anybody have any idea as to why?
Regards,
Jie

Not a silly question at all. I was running it under Apache::PerlRun
instead of Apache::Registry. However, I made the change,
stopped and started Apache, and tried again, and got the same
@INC error.

This may be a silly question, but are you executing your script under
Apache::Registry or just as a regular cgi script? Apache::Registry allows
you to run (mostly) unmodified perl cgi scripts under mod_perl, but the
scripts have to be executed from a location which has Apache::Registry as
its PerlHandler.
For instance, in httpd.conf:
<Location /perl>
SetHandler perl-script
PerlHandler Apache::Registry
PerlSendHeader On
Options +ExecCGI
</Location>
Then your script would go in <DocumentRoot>/perl.

Try putting a debug statement into the BEGIN block in your startup.pl:
print STDERR "Running startup.pl\n";
If you see this message in your error_log it means your startup.pl is
getting executed (and I'll be very surprised...:)
