I have a Mason application that runs fine with Postgresql 7.4, Apache
1.3 and the appropriate version of mod_perl.
I am moving this application to RedHat Enterprise Linux with
Apache/mod_perl 2 and Postgresql 7.4. After a bit of agony I now have
a working mod_perl2/Mason environment on RHEL.
I moved my application code over over and changed a few Apache calls
to Apache2 calls and now the application at least loads and displays
the home page. I'm having a strange problem with sessions. The first
time through the code everything seems to work, i.e. I get a cookie
from the client web browser and use the value of the cookie to restore
the users session. The SECOND time through, however, the application
hangs while trying to restore the session.
I am using Log4perl to track the trail through the application. I have
turned on logging in Postgresql (debug3 so far) and things look normal
to me.
Here is a snippet of code from my 'get_session.mas' that restores a
user session if one exists and creates a new session if one does not
exist:
if ( exists($cookies{$Blb::cookie_name_id}) ) {
$session_id = $cookies{$Blb::cookie_name_id}->value;
$log->debug("FROM COOKIE: $session_id");
# Re-create our existing Apache::Session using existing session id
eval {
tie %session, 'Apache::Session::Postgres', $session_id, {
Handle => $sess_dbh,
Commit => 1,
AutoCommit => 1,
Generate => 'ModUniqueId',
};
$log->debug("After tie");
}; # end eval
$log->debug("After eval");
...
When it works I the output from all of the $log->debug statements.
When it hangs I only see the "FROM COOKIE: $session_id" message in the log.
The Postgres log shows a select statement that is selecting the
session based on the session id. I can cut and paste this select into
a postgres client session and it works.
Has any one else experienced any thing like this before?
