Probably off topic but 113 errors and Netcache
I've got a bunch of sites using cookies to authenticate and to pass some (crypted) hashes around. I've got one guy behind a "netcache" proxy server (his cable modem provider apparently routes everyone through it) gets a 113 error when trying to access one of my mod_perl scripts. I dont think this is a mod_perl problem at all, just something about the proxy (everyone else is doing ok, even people behind other proxies- however they are not in an http-accel mode proxying). I'm trying to find an answer on the web, but I keep getting all these server logs and error pages and such making narrowing the search alot harder. I have this horrible feeling this question is covered somewhere that I should now about :) but I cant seem to find it. Suggestions on a better place to ask this question are welcome. Here is the error message from an ie5.5 win2k browser, but the source shows a NetCACHeError as a commnet, which makes me almost certian its coming from the proxy ERROR: The requested URL could not be retrieved While trying to retrieve the URL: UNKNOWN URL PERSISTENT The following error was encountered: ERROR 113 -- The syntax for the URL you entered is not valid. This means that: You made a typing error or the URL you entered might not follow the rules for the syntax of URLs.

Is *anybody* running perl 5.6, modperl_1.25, apache_1.3.17 PHP 4.0.4pl1 OK ?
Hi Has anybody managed to get the combination in the title coexisting happily ? My platform is Solaris 2.6 and my perl config is listed right at the bottom of this message. Evrything compiles without complaint. PHP works fine, Sablotron (via Perl PHP) works fine, but any script using XML::Parser or XML::XPath itself just bombs. Outside of mod_perl the scripts run fine. I've got the latest versions (Parser 2.30 XPath 1.04). A couple of backtraces I got from gdb running scripts are below. If I comment out the LoadModule / AddModule for php4 in httpd.conf the scripts work. A script using XML::XPath gives (gdb) run -X -D -f /export/tools/apache/conf/httpd.conf -d /export/tools/apache/perl Starting program: /export/tools/apache/bin/./httpd -X -D -f /export/tools/apache/conf/httpd.conf -d /export/tools/apache/perl Program received signal SIGSEGV, Segmentation fault. 0xef396200 in XML_ErrorString () from /usr/local/lib/libxmlparse.so.1 (gdb) bt #0 0xef396200 in XML_ErrorString () from /usr/local/lib/libxmlparse.so.1 #1 0xef396088 in XML_ErrorString () from /usr/local/lib/libxmlparse.so.1 #2 0xef3918fc in XML_SetBase () from /usr/local/lib/libxmlparse.so.1 #3 0xef48d14c in my_fclose (fd=0x8fa340, MyFlags=-280440836) at my_fopen.c:68 #4 0x13303c in Perl_pp_entersub () #5 0x12c03c in Perl_runops_standard () #6 0xe1b60 in S_call_body () #7 0xe186c in perl_call_sv () #8 0x49314 in perl_call_handler () #9 0x48964 in perl_run_stacked_handlers () #10 0x46594 in perl_handler () #11 0xa9738 in ap_invoke_handler () #12 0xc66c0 in process_request_internal () #13 0xc6744 in ap_process_request () #14 0xb9d60 in child_main () #15 0xb9ff4 in make_child () #16 0xba210 in startup_children () #17 0xbac00 in standalone_main () #18 0xbb7fc in main () A script using just XML::Parser gives gdb) run -X -D -f /export/tools/apache/conf/httpd.conf -d /export/tools/apache/perl Starting program: /export/tools/apache/bin/./httpd -X -D -f /export/tools/apache/conf/httpd.conf -d /export/tools/apache/perl Program received signal SIGBUS, Bus error. 0x9970a0 in ??

Try setting LD_LIBRARY_PATH to wherever your xml lib is located. Another possiblity is that you're using the old Sablotron.so (0.44) rather than the newer one... I've never used Sablotron, but I've had similar problems with ld.so and oracle (libclntsh.so). In almost every case, setting the LD_LIBRARY_PATH to the correct path fixes the error.

Doesn't that sound a whole lot simpler? I think you are over-evalutating the stress on my server. With the speediest time base I was talking about (once per minute cron job), that would be 1440 HEAD requests per day, each requiring 1 simple database query that will most probably return no row at all (a query that returns many rows is slower, because it has to transmit these rows). Many sites with database-driven pages have multiple complex queries on some pages and run in the millions of page-views per day. As for the simplicity, having multiple individual custom cron jobs is simpler than one single generic cron job? But still, I don't like my solution very much either. My problem lies in the case where I get a lot of hits, I want to be careful of what I run in my cleanup handler (if I hit the database at every cleanup, I'll start piling up daemons if I get plenty of hits). I was thinking of having a variable with a timestamp of when we last checked the database, and getting into a cleanup handler, we'd hit the database only if it was more than a minute ago that we checked. -- Implementation: n., the fruitless struggle by the talented and underpaid to fulfill promises made by the rich and ignorant.

Perl sections / Location problems
I've been scratching my head on this for quite a while and I cant seem to
figure it out. I have a very stripped down configuration, which only contains
the following Perl section:
Perl
use Apache::Status;
$Location{"^/perl-status-1\$"} = {
SetHandler = 'perl-script',
PerlHandler = 'Apache::Status'
};
$Location{"^/perl-status-2\$"} = {
SetHandler = 'perl-script',
PerlHandler = 'Apache::Status'
};
/Perl
If I start the server up, it appears to configure correctly, however, if I
access /perl-status-1 I get a 404 Not Found error. If I access /perl-status-2,
then I get the expected Apache::Status output. This is very repeatable in that
no matter what I shove into the Location hash if its a regexp, the first entry
doesnt work.
I'm running Apache 1.3.17, mod_ssl 2.8.0, perl 5.6.0, Linux 2.2.16

Newbie question about AuthCookieDBI
Hi all, I am a newbie user of mod_perl trying to work with Apache::AuthCookieDBI and have been running into several obstacles. I'm hoping someone can point me in the right direction. I just installed Apache::AuthCookie successfully and was able to get it to work with the necessary changes in my httpd.conf file. Now I want to use Apache::AuthCookieDBI to authenticate against a database table. However during my installation, while doing the 'make test' I get the following error message --- Can't locate object method "module" via package "Apache" at /usr/local/lib/perl5/site_perl/5.6.0/Apache/DBI.pm line 202.

DBI+mod_perl SegFault!
Hi all-
I'm really having a problem I hope I might be able to get some help
with. I'm using Apache 1.3.14, mod_perl 1.24, DBI 1.14, MySQL Modules 1.2215,
Perl 5.6.0, and MySQL 3.22.32. (I think that's all that's relevant)
In my httpd.conf I have the following:
#--
Location /testing
SetHandler perl-script
PerlHandler Testing
/Location
#--
And I have a script called Testing.pm that looks like this:
#--
package Testing;
use strict;
use DBI;
sub handler {
print "Content-type:\n\nhtmlheadtitletest/title/headbodypre";
print "Getting Data Sources...\n";
my @drivers = DBI-data_sources('mysql');
print "Done Getting Data Sources...\n";
foreach my $foo (@drivers) {
print "DataSource- $foo \n";
}
print "Getting Data Sources Complete...\n";
print "/pre/body/html\n";
}
1;
#--
Consistantly, I get a SegFault when going to /testing. Using strace, I see
that it actually calls DBI and gets the valid results. Everything looks good
to me, but it dies after closing the FD.
The funny thing is, if I modify the Testing.pm module to be test.pl, it works.
#--
#package Testing;
use strict;
use DBI;
#sub handler {
print "Content-type:\n\nhtmlheadtitletest/title/headbodypre";
print "Getting Data Sources...\n";
my @drivers = DBI-data_sources('mysql');
print "Done Getting Data Sources...\n";
foreach my $foo (@drivers) {
print "DataSource- $foo \n";
}
print "Getting Data Sources Complete...\n";
print "/pre/body/html\n";
#}
#1;
#--
Anybody have any ideas? I've tried everything I can come up with.
Thanks,
-Eric.

Newbie question about AuthCookieDBI
Hi all, I am a newbie user of mod_perl trying to work with Apache::AuthCookieDBI and have been running into several obstacles. I'm hoping someone can point me in the right direction. I just installed Apache::AuthCookie successfully and was able to get it to work with the necessary changes in my httpd.conf file. Now I want to use Apache::AuthCookieDBI to authenticate against a database table. However during my installation, while doing the 'make test' I get the following error message --- Can't locate object method "module" via package "Apache" at /usr/local/lib/perl5/site_perl/5.6.0/Apache/DBI.pm line 202.

Re: cron for mod_perl?
Perrin Harkins wrote: Sure, but why waste resources? Because it's easy? :-) As for the simplicity, having multiple individual custom cron jobs is simpler than one single generic cron job? Yes, much simpler, at least for the scheduling and dispatching part. Instead of designing database tables to hold timing info on jobs and code to check it that is smart enough to remember when it last ran and prevent race conditions, you can write a simple crontab with one call to wget per job. The actual implementation of the jobs is pretty much identical either way. I guess two persons "simpler" aren't always the same: I find it easier laying out a table and querying it than hacking something to fiddle with my crontab safely. Do it whatever way suits you. I'm just suggesting that you try the lazy way if possible. I could mash the two together: have a single URL trigger that looks up the tasks to do in a database, but have it schedule it's next run itself using "at". Whew, there *is* a whole lot more than one way to do it! :-) I was thinking of having a variable with a timestamp of when we last checked the database That will have to be some sort of shared memory or file-based thing, since you won't be using the same process each time. I was intending on being lazy and let a bunch of processes find out there is nothing to do because one of them already did the work. ;-) Ahh, the joy of wasting resources...

location and directory directives
Hi All, I have been trying to go through the document directories, find out all the .htaccess files (which have their own authen/author configurations), parse and merge the authorisation info with the mod_perl authentication/authorisation directives in the server config file via the Perl section. The easiest way seemed to me was to use the DirectoryMatch in the server conf (with AllowOverride None), but it seems Apache did not start the authentication process at all unless I used a Location or LocationMatch. Any one have any idea on this? I'm using mod_perl 1.25 and A1.3.17. Thanks, Jie

Apache-read timed out
Hello , I am getting "Apache-read timed out messages in my error_log,now i have been looking at this problem for a while now before posting it for help, whats happening is if i test my application from within the network , because the connection being very fast i am not having any problems , but when i try to do the same thing from the external network over a dial up line i get this error message in the error logs and the script gets killed What we are doing is we are uploading large amts of data using HTTP POSTS ,so at the server end i am using the Apache-read function to get the body of the post. I have even tried this by making the application point a cgi-bin/perl script rather than a mod perl script , could this problem be because of buggy read function or is it that some other request running on the same client might have read my STDIN . The reason i say this is some times i have observed if i reload the webserver and immediately try to post something the chances of the upload going thru are good but if i try the same thing after the webserver has run for a while then the post always fails in a time window of around 165 secs . This particular bug was supposed to be fixed in production days ago but still i don't have any clue . i have even tried to write a small client using plain sockets and making the client sleep for some secs after posting each line of the body just to increase the time required for posting the whole content.

Re: cron for mod_perl?
Perhaps I've missed something, but in all this discussion no one has asked what it is you're trying to do. All I know is that you want to schedule something in a database and then check that database every minute (or so) and process the scheduled somethings. Generally speaking, 'at' is the simplest alternative. I've used 'at' in similar circumstances (though never from the web). However, this does not meet your needs of using a cached database connection. Another possibility is to write a daemon yourself and use some type of IPC or RPC to schedule events to that daemon. As the daemon runs, it just forks off and processes the scheduled jobs as those times pass. This requires some crafty work with sig alarm or other mechanism. I once remember seeing an alarm lib somewhere that would allow you to set more than one alarm. Without knowing what it is you're trying to implement, I think we've just about exhausted the possibilities for a scheduler within mod_perl/apache.

Performance Tuning -- How do I determine the correct value for RLimitMEM?
I have a modper/DBI/Oracle8i/solaris2.7 site and I'm having performance problem because I have too many apache processes that are too big. The machine grinds to a crawl for a normal amount of users. The problem is that at server startup I immediately have a bunch of apache process that are already using swap, but I have 4GB of RAM. What's going on?? See the output of top below. It looks like the apache processes are not using all the available memory. From top, RES gets lower than SIZE, why? Should I adjust RLimitMEM, and if so, how to I determine the correct value?

hey all, I built apache/mod_perl using the PREFIX argument, but am puzzled by the results. I assumed that the Perl modules would be installed into the location specified by PREFIX(according to Stas's guide), which is the case if the location is absolute, but not if it is relative(Stas's guide uses an example with an absolute location- http://perl.apache.org/guide/install.html#Installation_Without_Superuser_P ).

I've pretty much done with the modules chapter for the book (of course I didn't document all of them, it'll require a separate book if I did. but quite many are documented). So please take a look at this list and tell me whether I've missed something and you want it to be on the list. Note that I've re-grouped the modules differently from the original Apache::* list. Thanks. You're missing Apache::MimeXML, a PerlTypeHandler (actually the only PerlTypeHandler on CPAN IIRC) I know. I thought you are going to document this anyway :) And one has to get AxKit for this module... I've added the reference to AxKit which wasn't in the original post.
