modperl 2.0: apache crashes when running modperl script
I get an Internal Server Error in the browser when trying
to access the URI /hello.
Apache and modperl version:

I am not sure if the problem is with apache or modperl.
I could not find a core file under httpd ServerRoot.

Where did you take this example from? you should return a constant Apache::OK,
not a string Apache::OK. You need to import this constant before you can use
it. Here is a skeleton:
use Apache::Const -compile = 'OK';
sub handler {
...
return Apache::OK;
}

Re: [OT] Apache::DBI and Postgres

Not really a problem (yet), but out of curiousity...
I'm using Apache::DBI with postgres and while not serving requests, all
the postgres processes are listed as idle in transaction. Obviously,
the DBI connect statements are configured with AutoCommit = 0. It
doesn't seem to cause any real problems, but it does concern me that
postgres considers itself in a transaction with only a connect (i.e.
prior to a $dbh-prepare()). I threw some SELECTs at it and it's fine,
but I worry about transaction blocking under heavier load and with
INSERT, DELETE, and UPDATE statements. ...or maybe I'm just thinking too
Oracle-ish about it.
I noticed an interesting problem with regards to dates and times. If
you have columns that you let pgsql fill in, frex:
Column |Type | Modifiers
--+-+---
order_date | date| default date('now'::text)
order_time | time with time zone | default ('now'::text)::time(6) with time zone
Those dates and times will tend to be off, because pgsql uses the
exact date/time at the _start_ of the transaction. And with Apache::DBI
the transaction could have been started quite some time ago, unless your
server is heavily loaded and/or you do lots of SELECT queries before
adding new rows (thus making sure you end up with a relatively fresh
transaction).
Just to illustrate this, I first get the current time on my server:
dev= SELECT current_time;
timetz
20:11:20.787832-04
Then I go to my mod_perl application and add a new account. The
resulting row has:
order_date | order_time
+
2003-06-01 | 20:10:46.349862-04
And order_time in this row is chronologically before, even though I
added the account _after_ typing 'SELECT current_time' in my psql
console...
The date can be off too, if Apache::DBI used an old, stale transaction
that started the previous day (this is very possible if a new record is
added alightly after midnight...)

mp2: session/auth handlers stable enough to use?
I'm looking at Apache::SessionX from Embperl as a possible session tracker for an app I'm doing with Template::Toolkit, has anyone any comments/suggestions re how mature this, (or any other recommendations?) session tracking module is under mp2? I've read some comments on CPAN discussing the use of tie() and performance, which I confess to knowing nothing about. Is any of this relevant to mp2? I want to avoid 100% any use of the compat stuff in mp2, and make this as pure an mp2 site as possible. thanks :) Carl
RE: trouble with using $r-lookup_uri()
I'm trying to write a authentication handler using mod_perl, and am encountering some difficulty. I have isolated my problem to the usage of the lookup_uri($uri) function call - whenever I call it, my module segfaults. I have tested the input with both a variable string, and just a quoted string, and get the same result. I don't know whether this will help you, but don't just focus on this handler. I encountered problems using lookup_uri myself, because I did not bear in mind that -lookup_uri goes through a request cycle itself, thus calling a far lot of the handlers defined for that uri. However it is not a complete request, so things like -pnotes etc. can fail. See http://marc.theaimsgroup.com/?l=apache-modperlm=105118150200822w=2 for my 'diary'. --Frank
Missing html code using dynagzip

Does anyone know why this happens? I've tried putting all my output into one print statement. Makes no difference. Scott

[port to mp2] Apache::MP3
I've ported Apache::MP3 to mp2. I'm not submitting it as a patch yet, since I want to try to make the changes co-exist with mp1. This package currently works only with mp2: http://stason.org/tmp/Apache-MP3-3.04.tar.gz This a temporary location and will be gone once I submit the changes to Lincoln and he releases a new version. I've also cleaned up the code to emit no warnings and be a bit less error-prone (as I tested with no so perfect mp3 files). Still there could be problems, but it should be good enough to start with. p.s. Lincoln, do you have any changes since 3.03? If so, can you please send them to me so I work with the latest version.
