RE: Bugs 5.6.0 modperl use?
We are running 5.6 on 2 production servers with mod_perl 1.23 and 1.24, Apache 1.3.12, Apache::DBI, DBD::Sybase (to MSSQL), and DBD::mysql. One box is Linux. The other is Solaris 2.7. So far no issues other than "depreciated" notices on some modules, and our own programming errors. Serving ~6M dynamic page views per month between the two boxes.

URL rewriting logging
Hi,
I'm trying to use Eagle book-like URL rewriting to track sessions and
I'd like to log session id in the 'user' field (so Analog can do all

You can log anything in $r-notes with log_config using the %{}n notation.
Say you put your session in $r-notes('SESSION' = $session).
You would log it as %{SESSION}n

does mod_perl with USE_DSO=1 require perl built with -Duseshrplib ?
I have a number of apache servers on various hosts, not all of them are to be mod_perl enabled. So, I tried to build apache with mod_perl as a DSO in order to enable mod_perl via the httpd.conf file if needed. I tried building mod_perl-1.24 as a DSO for apache-1.3.14 on my Irix platform. Building went well, I got a libperl.so etc. However, the resulting httpd failed during make test, with a message about not being able to find PL_curpad when loading IO.so - similar to what is described in mod_perl_traps.pod. The unsatisfied symbol is in libperl.a. This looks like mod_perl as DSO *requires* perl to be built with -Duseshrplib . Is this correct? I like the improvements in mod_perl Makefile.PL which checks consistency between perl and apache regarding -D_LARGEFILE_SOURCE. If USE_DSO=1 requires a perl built with -Duseshrplib, perhaps mod_perl Makefile.PL could be modified to check this as well? --- benedict -- Benedict Lofstedt [EMAIL PROTECTED] University of Aarhus, Department of Computer Science Fax: + 45 8942 3255 Building 540, Ny Munkegade, DK-8000 Aarhus C, Denmark.Phone: + 45 8942 3222

Hi there, On Thu, 25 May 2000, Ime Smits wrote: | [error] Undefined subroutine Apache::ASP::handler called. | what does it mean? | How to fix it? I think something went wrong during the Apache::ASP installation. Consider installing Apache::ASP once again with the cpan installer (possibly use force install) and examine the output very carefully for missing dependencies. My experience is that most of the time a single "install Apache::ASP" in cpan isn't sufficient and the installer doesn't seem te resolve all dependencies right automatically, so you have to do some things manually on a really clean system. And... don't forget to restart your mod_perl enhanced Apache after that. And make notes about what you do as you do it. If you find that there are any missing dependencies, post details to the List.

Re: Cache control
In our experience the only thing that guarantees no cacheing is returning 302. Also appending a query string (even an empty one) to the redirect URI seems to make it even more solid. So in your script you would build up your destination URI, append '?foo=bar' to the end of it, and return it as a redirect. That way not even MSIE will cache it.

Apache::ASP doesn't initialize variables?
I've noticed something peculiar with Apache::ASP. It does not seem to be initializing variables to 0. That is, if I load one ASP webpage that sets a variable to X, then in the next ASP webpage the variable is initialized to X instead of 0. Is this intended behavior, or is it a bug? Also, I was wondering if there is a way to make Apache::ASP print more meaningful error messages when a compile error is encountered, instead of "500 Internal Server Error". Right now I have to look in my HTTP error log, which gives something like this: [Fri May 26 05:56:54 2000] [error] [asp] [31714] [error] Bad name after Arrest' at (eval 31) line 96. -- , /usr/lib/perl5/site_perl/5.005/Apache/ASP.pm line 1180 Bareword found where operator expected at (eval 20) line 96, near "'yuarrest/|You're" (Missing operator before re?) This also does not tell me the filename of the script that caused the problem, so sometimes I have to guess when my script uses #include file.

In visitorinfo,.cgi, I have following steps print "Content-type: text/html\n"; print "$mycookie\n"; print "Location: /scripts/visitorinfo.cgi?pageid=mailhdramp;lang=EN\n\n"; exit 0; It really goes to the page mailhdr with appropriate details.

Apache::GzipChain and scalability
I tried out Apache::GzipChain for dynamic mod_perl pages (using Apache::Registry), and it was great for reducing the download time (especially over modem). I am seriously thinking about using it for our production environment. However, some people are concerned about it using up too much resource. Has anyone looked into scalability issues? Would I see significant reduced throughput using GzipChain? Also why don't most sites gzip their pages (do redirect based on browser support)? ___ Why pay when you don't have to?

Problem with mod_perl
Hi all, Sorry if it is an incorrect list to ask... I have a strange problem with mod_perl. I've tested mod_perl using a very simple scripts (one of them is attached). The network load is emulated via LAN using a special proggy. The problem is: under load above 20 requests per second after working some time (about 15-30 sec) Apache daemon stopts accepting new connections and blocks forever (without -X option httpd at this moment begin forking until it eats all resources) . I've found that the problem exists only when scripts use modules (tested with CGI v 2.46, IPC::Shareable, our own modules). Test scripts without modules work fine even under load of 200 requests per second. I observed this on two machines, both under FreeBSD/i386 (3.3-RELEASE and 3.4-RELEASE, kernel options: maxusers 256, NMBCLUSTERS=4096). I've tried Apache v. 1.3.9 through 1.3.12, perl 5.005_03, mod_perl 1.22 and 1.24. Most Apache's config variables have default values, except that I added several lines which are nessesary for mod_perl scripts: Alias /scripts/ /usr/local/www/scripts/ Directory /usr/local/www/scripts SetHandler perl-script PerlHandler Apache::Registry PerlSendHeader On PerlModule CGI Options +ExecCGI /Directory -- Regards, Eugene. test2.ple

Well forcing you to write objects does not mean you know how to write good objects.

mod_perl, multiple virtual hosts, and DBI weirdness
Hello all... Having a wacky problem that I can't seem to figure out... (Apache-1.3.12, mod_perl-1.24, ApacheDBI-0.87) I have two NameVirtualHosts, we'll call them host1.foo.com and host2.foo.com, both running on the same IP on the same server. Both are similar sites, so I've moved a lot of code common to both sites into library files - there's a library for database access, utilities, ecommerce integration, etc Each library file defines its own package (although it is NOT object oriented). I also have site-wide configuration files for each site which also define their own package. Now, here's my problem... host1.foo.com was developed first... it runs fine... I finished host2, and started testing it, and discovered that when both host1 and host2 are running, and users are hitting both sites, sometimes the configuration gets messed up. For example, I have a search page on each site with drop-down boxes for options. Host1 will sometimes display options for Host2, and vice-versa -- these options are being dynamically generated from the databases, so it looks like the scripts are sporadically using the wrong database handles. The file structure looks like this: host1/ perl-bin/ bunch of .cgi scripts that run under mod_perl config/ all of my .pl library files and a .rc config file doc/ host2/ perl2-bin/ bunch of .cgi scripts that have the same names (but are different) than those in host1 config2/ all of the .pl files (exactly the same files as in host1 - I had actually symlinked them at one point) plus a different .rc file doc/ The package names in the library files are the same across both sites... there's package dbAccess, cgiUtil, etc site.rc declares package "site" for both sites, and contains database name, login info, and such... Anyway... I had thought that because the URIs are different, it wouldn't matter that the package names are the same from one site to another-- on host1, search.cgi has this: require "config1/site.rc"; require "config1/dbAccess.pl"; and on host2... require "config2/site.rc"; require "config2/dbAccess.pl"; ... But this doesn't seem to keep the server from sporadically crossing database handles... I hope I've explained this well enough that someone can figure out what I've got and help me fix it...

Apache::Session::Pg blob support?
Hello there... I was wondering, with the new Pg-specific support you've got going with Apache::Session, does it handle Pg blobs transparently? The regular limit on the size of a tuple in Pg is 8k, which can be a problem if I'm trying to put more than that into my Apache::Session tied hash. (Yes, I do that sometimes. It's a handy place to hide stuff, those sessions...) If that's not part of the new release, probably me and/or another guy I'm working with is going to code that up.

Having a wacky problem that I can't seem to figure out... (Apache-1.3.12, mod_perl-1.24, ApacheDBI-0.87) I have two NameVirtualHosts, we'll call them host1.foo.com and host2.foo.com, both running on the same IP on the same server. Both are similar sites, so I've moved a lot of code common to both sites into library files - there's a library for database access, utilities, ecommerce integration, etc Each library file defines its own package (although it is NOT object oriented). I also have site-wide configuration files for each site which also define their own package. Now, here's my problem... host1.foo.com was developed first... it runs fine... I finished host2, and started testing it, and discovered that when both host1 and host2 are running, and users are hitting both sites, sometimes the configuration gets messed up. For example, I have a search page on each site with drop-down boxes for options. Host1 will sometimes display options for Host2, and vice-versa -- these options are being dynamically generated from the databases, so it looks like the scripts are sporadically using the wrong database handles. The file structure looks like this: host1/ perl-bin/ bunch of .cgi scripts that run under mod_perl config/ all of my .pl library files and a .rc config file doc/ host2/ perl2-bin/ bunch of .cgi scripts that have the same names (but are different) than those in host1 config2/ all of the .pl files (exactly the same files as in host1 - I had actually symlinked them at one point) plus a different .rc file doc/ The package names in the library files are the same across both sites... there's package dbAccess, cgiUtil, etc site.rc declares package "site" for both sites, and contains database name, login info, and such... Anyway... I had thought that because the URIs are different, it wouldn't matter that the package names are the same from one site to another-- on host1, search.cgi has this: require "config1/site.rc"; require "config1/dbAccess.pl"; . and on host2... require "config2/site.rc"; require "config2/dbAccess.pl"; But this doesn't seem to keep the server from sporadically crossing database handles... I hope I've explained this well enough that someone can figure out what I've got and help me fix it... Thanks... e. [EMAIL PROTECTED]

[OT] Tone on this list
I've been lurking on this list for a long time, learning tons, implementing some things on my own, helping out as I can (which isn't much). I feel like I know all the frequent posters on the list by now. It's funny how that happens, but I can recognize each person's "tone," like a familiar co-worker. I really enjoy the friendly atmosphere, and how much help and information flows here. Now and then, someone new posts, and sometimes s/he gets off on the wrong foot. One problem is the medium. I know I've made the mistake in the past (hopefully not on this list) of being too passionate in my phrasing, and it can be very easily misinterpreted, smilies notwithstanding. All in all, I'm proud of this list's tone. As always, when a problem is laid before others, it's necessary to work through the chaff in order to convince everyone that it isn't some problem we've seen before, or some issue we've beaten to death. Until we establish some independent credibility here, we are likely to get a number of answers that aren't correct, and maybe even a bunch of blow-off answers that are way off-base. But this list always gets to an answer eventually, and that's what's great about it. I'm sorry that Marc Lehmann got some private answers that annoyed him. As someone posted recently, maybe one solution is to keep substantive dialogue on the list, and then we can make sure not only that our discussion is moderated properly, but that others can share the information.

I call finish on my statements explicitly when I can, but if something

Maybe this should be folded into Apache::DBI, like the automatic rollback?

Currently, using Cdefined() on an entire array or hash reports whether
memory for that aggregate has ever been allocated. So an array you set
to the empty list appears undefined initially, and one that once was full
and that you then set to the empty list still appears defined. You

This module has come a long way in the time I've been watching the list. A couple of notes on the Oracle storage module: - Using "FOR UPDATE" forces the transactional lock model. Is it possible to make this optional? The other modes allow the use of a "enforce data integrity only" locking style which is sometimes needed. I'm less worried about people overwriting their own session data than I am about stale locks, although I suppose Apache::DBI's cleanup handler should take care of them. - Oracle (the company) says not to use LONG anymore. They are trying to move everything to CLOB/BLOB. I modified my Apache::Session::DBI to support this, which mostly involved specifying "ora_type = ORA_BLOB" in my bind variable parameters. Maybe we need and Oracle8 module, separate from the standard one? By the way, BLOBs don't work with synonyms, so you have to specify the schema name in the SQL when using them. I know you were working on a BerkeleyDB storage module. Are you still working on it, or did you throw up your hands in disgust over the BerkeleyDB module? Although I don't have time right now, I could eventually work on this if you aren't already doing it. Finally, everybody loves benchmarks. Do you have any cool speed comparisons between the various storage and locking options? I'm sure the list would be very interested.

At the point that the data reaches a critical mass, then it is likely that the data is getting more crucial to the application. If the data is crucial to the application, that also tends to mean that it would be best served (ultimately) by having an appropriate data structure where the session ID happens to be a key. eg I may make a file based session for just storing sundry things, but I would rarely want to store a shopping cart for a web store inside a session. A shopping cart is a data structure that has potential links to other information such as inventory tables. Now, the cart should be tied to the session id anyway, but whether the data should be stored as one big blob is another issue. Another thing about huge sessions is that depending on your locking and concurrency considerations, one big blob can become suboptimal for performance if you are not careful. Anyway, I guess this is just a philosophical issue with me. I know others like to store everything in their sessions. :) Later, Gunther __ Gunther Birznieks ([EMAIL PROTECTED]) Extropia - The Web Technology Company http://www.extropia.com/

It is included and tested in this release. This is the only change from 1.50. http://www.cpan.org/modules/by-module/Apache/Apache-Session-1.51.tar.gz This new stuff looks really good. This module has come a long way in the time I've been watching the list. A couple of notes on the Oracle storage module: - Using "FOR UPDATE" forces the transactional lock model. Is it possible to make this optional? The other modes allow the use of a "enforce data integrity only" locking style which is sometimes needed. I'm less worried about people overwriting their own session data than I am about stale locks, although I suppose Apache::DBI's cleanup handler should take care of them. I assume that if people are using a transactional database, they are knowledgable about transactions. That's why I made the Commit argument mandatory for the Oracle and Postgres backing stores: it forces people to consider their transaction policy. - Oracle (the company) says not to use LONG anymore. They are trying to move everything to CLOB/BLOB. I modified my Apache::Session::DBI to support this, which mostly involved specifying "ora_type = ORA_BLOB" in my bind variable parameters. Maybe we need and Oracle8 module, separate from the standard one? By the way, BLOBs don't work with synonyms, so you have to specify the schema name in the SQL when using them. That's lame. So, we would need to pass the schema name as an argument? Remind me again what's wrong with LONG? I know you were working on a BerkeleyDB storage module. Are you still working on it, or did you throw up your hands in disgust over the BerkeleyDB module? Although I don't have time right now, I could eventually work on this if you aren't already doing it. Finally, everybody loves benchmarks. Do you have any cool speed comparisons between the various storage and locking options? I'm sure the list would be very interested. Even better would be a little benhcmarking script that people could use on their own systems to do comparisons. Maybe i'll whip something up that;s portable. For benchmarks that aren't portable, check the b/ directory in the distro. -jwb
