On a RH6.0 (yes, ick) box without persistent DBI connections, the server side of the DBD::mysql connection was successfully closed (netstat shows nothing), but the client side shows a TIME_WAIT state, which hangs around for 30 seconds or so before disappearing.

On both RH6 (in the office) and Solaris (at the co-lo) with a middling-recent Apache and mod_perl, some pages were getting truncated when sent to the browser. This happens on a variety of browsers and a variety of pages. Once it happens on a particular combination of page and browser it's reproducible. Now, the page is definitely being completely sent to $r-print(), but it's not making it to the browser (or at least that's what tcpdump shows). Again, any bells ringing? Thanks, Dave

while (*pair (val = ap_getword(r-pool, pair, ''))) {

}
Here's a line from the ap_getword docs.
Copies everything from line up to stop to a new string. line is updated
to point to the first character after stop. Multiple occurrences of stop
are skipped if present.

Please don't modify the function ap_getword() in src/main/util.c as

No, I was trying to fix it in apache_cookie.c It could simply check if
the next char was '' before calling ap_getword.
I'd leave this new function in the same file (util.c) for a quick hack
but if you leave it like that then ten to one you'll forget it's in
there and have to do it all over again next time you upgrade Apache.
It's still better to find a way around the problem than to do

Re: compiling troubles on Solaris 8
As an aside, Solaris 8 comes with prebuilt versions of Apache and mod_perl, does anyone familiar with HP-UX, AIX, or IRIX know whether this is true of these platforms as well? Whether they are DSO mod_perl or not would also be helpful. HP-UX doesn't consider Perl a supportable piece of software, nor Apache. Needless to say, it doesn't come prebuilt. The compiler that comes w/the os isn't ansii compliant and is only good for rebuilding the kernel (but hey, you can buy HP's ansii c compiler for only a few thousand dollars!). We ended up building a gnu development environment in order to build mod_Perl. We could not get it to work as a DSO :(. Once we got everything up and running, it's a decent enough platform.

This is more or less how Alzabo works (but you can tweak it). When it fetches row objects, its really just fetching primary keys that match your query. As you request other columns they are fetched and cached. You can also specify some columns to be fetched with the primary key and specify that others should be considered a group (when A is fetched, get B C too). Actually, I stole a lot of this from Michael Schwern's Class::DBI and got some more ideas from your talk at ApacheCon, Perrin. So if people are interested in implementing this, they may want to just consider using Alazbo (or you can rip out the caching code and use that separately if you want). -dave /*== www.urth.org We await the New Sun ==*/

RE: Not embedding SQL in perl
Joe Breeden queried: It would be interesting to know how other people have solved that problem. Currently, we are essentially using embedded SQL in our apps. I have found that stored procedures + perl module wrapper around the procs. is a nice, balanced approach. The procs. give a nice performance boost as they are precompiled into the server (we use Sybase). I believe that they are more secure, in that you aren't dynamically generating sql that might be 'hijack-able'. You are providing a discrete amount of functionality. Placing the stored procedure execution code in a perl module makes for easy/clean perl access from the rest of the app. Moving to a new db isn't too terribly difficult in that the proc names will probably remain as well as the parameters that you pass. Also, how often do you move to another database in the life of a web app anyway (at least in our corporate environment)?

Apache 2.0 / mod_perl 2.0 / Win NT/2000 ? pipe dream ?
Hi all, We currently use (close to) the latest Apache / mod_perl environment on HP/UX. Our holding company is forcing a move to Win2k :/, but they still want to use our mod_perl apps :). I was looking for more information on mod_perl 2.0 today but didn't come up w/much. I have several questions. If you can answer or point to docs, I would be most appreciative. 1) Is moving to mod_perl 2.0 going to require large code changes (even on a *nix system)? 1a) Are there any web sites detailing the types of changes that will be required? 2) I am aware that Apache 2.0 should see a performance increase on NT. Will I be a able to run my current modules in this environment? 2a)Will it be a production level environment? 2b) What will be the performance repercussions (if it will be possible at all)? 3) Is there any commercial company that would provide tech support contracts in this environment (not that I've needed it so far, but the uppers like the safety net)? 4) Is the code base stable enough that I can compile and test this out (I really can't even find a site that deals w/ mod_perl 2 in any detail - probably looking in the wrong places - I would think that perl.apache.org would mention something? - am I blind? ) Thanks for any assistance you can provide.

Re: Not embedding SQL in perl
It would be interesting to know how other people have solved that problem. Currently, we are essentially using embedded SQL in our apps. I have found that stored procedures + perl module wrapper around the procs. is a nice, balanced approach. Definitely; stored procedures are hit-and-miss in a lot of environments. Remember that a large number of people in the mod_perl world can't use 'em because they (we) use MySQL. If one wanted to emulate this behavior with MySQL, you would essentially clone the functionality of your stored procedures using Perl + DBI inside your persistence layer. That is a perfectly viable approach too, but a lot less efficient than stored procedures (many roundtrips versus one). Interesting, I will be working w/MySQL in a few days on a side project of my own. We'll see how my outlook changes ;) Any recommendations?

duplicate libperl.so causes problems on Tru64
Hi, I am using mod_perl-1.25_01 on Tru64 unix with apxs. The default packaging creates the DSO mod_perl as libperl.so. This causes problems on Tru64 unix as the loader cannot differentiate between libperl.so which is part of the PERL distribution and libperl.so which is the Apache DSO. I found the replacing libperl in apaci/Makefile with mod_perl (4 places) solved this issue. Given that Apache seems to use mod_*.so for library names. why not with mod_perl ?

There are many ways of specifying virtual hosts. A couple of alternatives
are to use mod_macro, or a mod_perl block to loop over your list of
domains.
I have been known to use this in the past, even though it's clunky...
--- snippet from httpd.conf
foreach (qw/host1.com host2.com host3.com host4.com host5.com/) {
$PerlConfig .=3D EOF;
VirtualHost 123.123.123.123:80
ServerName $_
ServerAlias www.$_
DocumentRoot /wherever/it/is/$_/
CustomLog/var/log/apache/multihosts_access_log vcommon
/VirtualHost
EOF
}
--- end snippet
By adding a script_alias here you can get what you need.

In fact, the schema creation interface is a set of Mason components. The caching/syncing architecture was specifically created to allow syncing of objects between multiple processes (ala mod_perl) and I will be creating a syncing module sometime that sync between multiple machines as well.

Tangram I don't know much about in relation to mod_perl. However, these are all fairly different systems. I often descrive Alzabo as the opposite of Tangram, for instance. Alzabo is an RDBMS-OO mapper and Tangram is an OO-RDBMS mapper. Tangram is aimed at letting you have transparent OO persistence in an RDBMS without worrying about the schema too much.

(new idea) RE: [OT] ApacheCon BOF
theme How about a picture of a card game; on the table are a 9 of diamonds, Jack of Clubs, and King of spades. The dealer is about to play the Ace of perl. The caption reads, "mod_perl does the trick". Also in the dealer's hand are cards that say, IIS iPlanet Servertec Xitami ... /theme The cards on the table are arbitrary. Perhaps some clever individual can code a secret message into the card selection. I'm also not sure what the 'Ace of perl' should look like, but we all know what the 'A' stands for. You can also pick your favorite competition, for cards still in the dealer's hand.
Charset?
Is there a mod_perl way to set the character set besides doing:
$r-content_type('text/html; charset=foo');
???
That'd be handy for a future version. I can't find anything in the
Apache.pm docs (1.24) or the guide for this.

I don't know what version of the guide they store on perldoc.com. I
suppose they convert it automatically from the sources on CPAN, which
explains broken links and incorrectly interpreted tags. You should read
http://perl.apache.org/guide/ instead.
As for your question, you don't need Apache::SIG, when you use
last if $r-connection-aborted;
However I don't know about Win32, may be Apache works differently there.
It works on Unix.
Above script works on Win32 also.

Please reply also by email..
Help is appreciated :-)
Here is my installation data:
Apache/1.3.14 (Unix) (SuSE/Linux)
mod_perl/1.24
By the way - I read at www.perldoc.com that mod_perl is considered alpha
at
win32... I am in the need of setting it up on win2000 with industrial
strength. Is that feasible?

My experience w/ mod_perl on Win32 (NT 4.0) is quite recent, and
only for development purposes.
I can't make a recommendation for or against.

[JOB SEEKER]: Me
My current contract is winding down and rather than rotting away at home I think I should try to get some sort of job. I know Perl and mod_perl very well, and Mason even better. I'd love to work on something large scale, and it goes without saying that I want to do Perl. I live in Minnesota but I won't be there much until mid-April so telecommuting work is preferred. If you have a quick contract in Pittsburgh for me (where I'll mostly be from now to April) that would work too. If my resume doesn't demonstrate make it clear, I am not a visual designer ;). However, I am quite good as an application designer and developer. My resume is online at http://www.urth.org/resume/ Of course, if someone wants to pay me to hack on Alzabo or Mason, don't be shy! -dave /*== www.urth.org We await the New Sun ==*/

Re: Perl Sections, NameVirtualHost, and Aliases
Has anyone successfully built a fully perl conf file with multiple virtual hosts on the same IP? I'm giving it my best, but just can't quite get it to work. I'm stuck on aliases. The Eagle book and the mod_perl guide have both been of great help getting this far, but I can't find an example of setting anything where "Directive is Repeated Multiple Times" (which may be an indication that it just don't work). Not a direct answer, but an alternative to fighting with the data structure is just just plug a programmatic $PerlConfig .= $string and build the VirtualHosts as if they were plain text. Not as elegant as doing this the hard way, but it's also easier to explain if you have to hand the config file off to someone who knows Apache but not Perl.
