RE: Embperl - where are the cookies ? Success....
$Apache::Session::SysVSemaphoreLocker::nsems = 16; (note - I'm running Solaris so I gotta have the nsems argument) I put the hint with nsems and Solaris in the Embperl docs (the missing BEGIN block is already added) Thanks for the hint Gerald
Re: Embperl - where are the cookies ? Success....
Hi Everybody -
Finally got it working, and I wanted to sum up what I did so if somebody
else runs into this, it'll be waiting for 'em in the archives.
In the startup.pl, here's what I got:
BEGIN{
$ENV{EMBPERL_SESSION_CLASSES} = "DBIStore SysVSemaphoreLocker";
$ENV{EMBPERL_SESSION_ARGS}= "DataSource=dbi:mysql:gpp8p_casenet
UserName=gpp
8p Password=x";
}
use Apache::Session::Embperl;
use HTML::Embperl;
$Apache::Session::SysVSemaphoreLocker::nsems = 16;
(note - I'm running Solaris so I gotta have the nsems argument)
The table:
mysql describe sessions;
+---+-+--+-+-+---+
| Field | Type| Null | Key | Default | Extra |
+---+-+--+-+-+---+
| id| varchar(16) | | PRI | | |
| expires | int(11) | YES | | NULL| |
| length| int(11) | YES | | NULL| |
| a_session | text| YES | | NULL| |
+---+-+--+-+-+---+
The test script:
html
h1Test of session features/h1hr
[+ if($udat{counter} == 0){$udat{counter} = 1} +]
The page is requested [+ $udat{counter}++ +] occasions
since [+ $udat{date} ||= localtime +]
br
cookies: [+ $ENV{HTTP_COOKIE} +]
/html
I think that covers it. Thanks for your help.

George,
This problem was mentioned in a previous post because it is wrong in the
documentation (it may be fixed now).
The setting of $ENV{EMBPERL...} variables in this case need to be inside
a BEGIN block at the start of the script. This is because the value of
these variables are used to setup session tracking right when the
HTML::Embperl module is used (and this happens before your EMBPERL
environment variables are being set).
So put a BEGIN {} around them and you should be ready to roll.
Incidentally if you are using starting and stopping apache by hand you
will see a message from Embperl when session tracking has been enabled.
If you do not see the message don't waste your time looking at your test
page.
Another thing, the reason things update randomly is because each apache
child is keeping a copy of what you put in $udat. Since it is a special
Embperl variable it will hold it's value and not be cleaned up at the
end of page execution like other variables are each time you reload you
get a different child with a different incrementing number.

I have been playing around with Embperl. I have a little script that
resembles the counter test mentioned in the docs, and it appears to
run. Problem is, no cookies get set. And the value of the counter is
erratic. One browser will appear to pick up the count from another.
Then it will jump back. Here is the script:
html
h1Test of session features/h1hr
[+ if($udat{counter} == 0){$udat{counter} = 1} +]
The page is requested [+ $udat{counter}++ +] occasions

br
cookies: [+ $ENV{HTTP_COOKIE} +]
/html

Incidently, $ENV{HTTP_COOKIE} never shows any value at all. I have the
session mechanics hooked up to a mysql database. Here's the setup stuff
in startup.pl:
$ENV{EMBPERL_SESSION_CLASSES} = "DBIStore SysVSemaphoreLocker";
$ENV{EMBPERL_SESSION_ARGS}= "DataSource=dbi:mysql:gpp8p_casenet
UserName=gpp
8p Password=xxx";
use Apache::Session;
use HTML::Embperl;
And BTW, I did set up the two tables in that database
Any ideas
