I've got a bit more info on this now. Nothing has changed on my PC (Linux RH 6.2) since this morning, other than updating Perl from 5.005_03 to 5.6.0. Apache::DB _was_ working fine. When I add a breakpoint, tab completion works fine to enter a sub name, and no errors are given by the debugger. However, doing an 'L' doesn't show any breakpoints, and no breaks occur. I've tried replacing perl5db.pl in 5.6.0 with the version from 5.005_03, but the behaviour is the same. Anyone else having this trouble? Anyone successfully used Apache::DB in 5.6.0? -- Jeremy Howard [EMAIL PROTECTED]

Prb: Apache::DB plus Perl 5.6 doesn't break
Well, that subject line looks a bit odd, doesn't it? What I mean is that with Perl 5.6.0, Apache::DB is broken, because it doesn't break... Er, that is, you can add breakpoints, but Apache::DB never actually breaks on them. Is anyone else having this problem? Is there a new version in the works? -- Jeremy Howard [EMAIL PROTECTED]

This obviously causes confusion - I'll turn it off, and make it manually configurable.

You never know. Perl comes up with smarter and smarter optimizations all the time. Perhaps if the same benchmark were run on Perl 5.003 you would get a different result. eg I think there was a thread on this list way back about OO method calls versus direct package references... and people said that OO method calls have a lot of overhead, but I think in later versions of Perl, OO method call paths are cached(?) and so method calls no longer have the same overhead as they used to.

No. You need to pass remote user to the browser using a form var then. I assume you are making use of JavaScript or Java or some other client side stuff. Your message is a little confusing to me as to what you are accomplishing since you open up with a server-side scenario and then close with a question about client-side behavior being affected by possibly setting $c->user? Anyway, if your concern turns out to be server side, writing a handler to set REMOTE_USER should be fairly simple since mod_ssl is extremely flexible with the information it exports to the environment from the digital cert. All you need is an appropriate set of mapping rules. BTW, just because you use digital certs does not necessarily preclude you from a basic auth system either for these old scripts. Digital certs are transferred on the SSL stream, Basic Auth credentials are transferred after the SSL Stream is authenticated. Although it seems a pain. Anyway, since I didn't quite understand where your issue comes from, I included more information than you probably wanted. Sorry about that in advance.

Just to expand on this - I turned stemming of words on by default in the search, which is why the stemmed words get returned. Perhaps it'll be better to turn stemming off by default, and rather make it a configureable option? > The :: are stripped on the fly, since these cannot be used in index, so > when you look for Foo::Bar you are actually looking for 'Foo && Bar'. That's a limitation of swish-e - you can configure it to index characters like $, !, ... as part of a "word", but the characters >, <, *, and : cannot be so indexed. So the script silently stripped ':' out, leaving the search term to be 'Apache' && 'Constants'. This should be mentioned on the search page Another thing that was configured in is that words have to be at least 3 characters long, which seems reasonable, and also there's some stopwords that don't get indexed, as they're too common. This list of stopwords is built by hand - so far it only includes 'perl' and 'modperl'. Also, the maximum number of hits is set at 30. best regards, randy

The reason for splitting on any =head level lies in fact that there are
huge sections under =head1 which have many =head{2,5}, and I'm slowly
reworking the Guide to making it more categorized (nested), rather than
flattened as it was before (and still is).
But we have thought about this issue. Look at the links at the bottom of
the splitted page -- it can take to the full version as well.

That's right. It's broken :( After searching for 'Apache::Constants' I've
got 'apach constant'...
The :: are stripped on the fly, since these cannot be used in index, so
when you look for Foo::Bar you are actually looking for 'Foo && Bar'.

No child process will ever try to serve more than request at once. These are not multi-threaded processes. - Perrin

Re: Confusion on Apache::DBI
Geoff, I know, once child dies, db handle goes out of scope and DBI cleans up the connection.. What I was asking is, we have directive called 'MaxRequestPerChild' for Apache server configuration which basically says how many request one child can process before it dies. So, if we have in 'httpd.conf' file 'MaxRequestPerChild 1000', that means, one child process will serv 1000 request and then it will die. Now, with Apache::DBI, we'll have one DBI handle per child process during the server startup. Now, let's say one child has started its processing and hasn't served any request yet. Now, first request comes in and it will look for DB handle, which is available and start processing it. Now, second request comes in for same child process and request for DBI handle, which is still serving first request. So, what happened at this time to second request?? Does it have to wait for DBI handle to be free?? That's my question.. I think, second request has to wait.. i.e. it will be the same as normal CGI.. only difference is, we'll save overhead of opening a DB connection each time request comes in.. Correct me if I am wrong.. And I'll look in DBI::Proxy .. Thanks again for your help Geoff..

Re: Confusion on Apache::DBI
Thanks Geoff, You were right... I was using "DBI:mysql:DBNAME::localhost" as connect string in startup file whereas "DBI:mysql:DBNAME" in my mod_perl script.. I have changed that and it worked... Now, another question.. As we agreed, we can have as many db handle available as server processes are running.. Now, can we set number of db connection per server process in script or in startup script or any other way??? Because what I see is in this way... Let's say a child process can handle 10 request and then dies.. now it has one db connection available.. and it is processing one request which uses available db handle.. now what happen if another request comes in and ask for same db handle??? does that request has to wait for that or what??? If yes, then is there any way we can set number of connection per process?? I mean each child process can have 5 db connection open at the same time.. and it can grow upto 10.. So, if all 5 db handle are in use, and if 6th request comes in then process will open another connetion and it can do like this upto max of 10 connection.. Is it possible??? has anybody done this kind of things before Thanks again for your help.. Niral Geoffrey Young wrote: >> >>

[JOBS] Spa.com
All this talk of Jobs has made me need to jump in and pitch spa.com. We're always on the lookout for good perl developers who want to work in mod_perl/HTML::Mason with a fun team in an awesome environment. We're based in Redwood City, CA ( Just south of San Francisco and just north of San Jose ). Its a casual relaxed environment in a fast track company. Bonuses include getting to work with Sonya( http://www.siberian.org/Sonya/ ) , The Siberian Husky and 'Bait', the fish that even our Program Manager can't kill. Currently at 20 employees we are looking to grow our staff rapidly in the next 4 weeks or so as we prepare for demand generation and large amounts of consumer traffic. I need developers at many different levels and we are a firm believer in promoting from within and allowing people to grow into new positions ( one of our content people surprised us with C++ skills, needless to say, he's not in content anymore ). I know I pitch Spa.com for [Jobs] regularly but it really is a great company that is going places and doing interesting things. Good options, good pay and a fun environment.

Apache::AuthDBI not setting $ENV{REMOTE_GROUP}
I've been using Apache::AuthDBI (and earlier, Apache::AuthenDBI) for a while, but never before have I used groups. I recently started trying to use groups, and with Apache::AuthDBI::DEBUG set to 2, I can get something like this in my error_log... 22310 Apache::AuthDBI::authz request type = >initial main< 22310 Apache::AuthDBI::authz user sent = >robf< 22310 Apache::AuthDBI::authz requirements: valid-user=>1< user=>< group=>admin< 22310 Apache::AuthDBI::authz user_result = OK: valid-user 22310 Apache::AuthDBI::authz return OK As you can see, Apache::AuthDBI::authz is getting the group name 'admin' from the database, but the group name isn't passed in to my CGI script (I'm using Apache::Registry) at all.

You tried to sell me that when I was at CP, and I didn't buy it then
either. This is a benchmark of .= versus join. 50 20-byte strings
are joined:
Concat: 2 wallclock secs ( 1.34 usr + 0.27 sys = 1.61 CPU)
Join: 4 wallclock secs ( 3.63 usr + 0.19 sys = 3.82 CPU)
.= concatenation is way faster. Also, building a 50-element array in
Perl takes up vastly more memory than building a 1000-byte string.
The string and the Perl process together require an RSS of 11MB, while the
array and the Perl process eat an RSS of 51MB.
Here is the benchmark program used:
my $iter = shift;
sub concat {
my $this;
for (my $i = 0; $i < $iter; $i++) {
$this .= 'A'x20;
}
}
sub arrayjoin {
my @this;
for (my $i = 0; $i < $iter; $i++) {
push(@this, 'A'x20);
}
join('', @this);
}
timethese(1, { 'Concat' => \&concat, 'Join' => \&arrayjoin });
The system was an Intel Pentium III 500 MHz with 128 MB of RAM and Linux
2.2.15. Swap was turned off.

Confusion on Apache::DBI
All, Sorry if this question sounds stupid.. but I am new to mod_perl and Apache::DBI.. I have successfully installed Apache Server 1.3.12 and mod_perl 1.24 and Apache::DBI 0.87 on Solaris 2.7. And I have tested all successfully... But confusion arised when I created a startup.pl file and tried to initiate DB connection in startup.pl file using 'connect_on_init' from Apache::DBI As I understood, if you have 'connect_on_init' in startup file, you have preloaded DB handle when first request comes in. And you don't need to open new db connection... But if I check the error_log file, I still have entry saying something like following: 10803 Apache::DBI need ping: yes 10803 Apache::DBI new connect to 'DatabaseNameUsernamePasswordAutoCommit=1PrintError=1' 10803 Apache::DBI disconnect (overloaded) And I will get this for first 4-5 request but after that each time I am getting 10803 Apache::DBI need ping: yes 10803 Apache::DBI already connected to 'DatabaseNameUsernamePasswordAutoCommit=1PrintError=1' 10803 Apache::DBI disconnect (overloaded) Why is that??? Shouldn't I supposed to get 'already connected to' statement right from the first request And how many open connection can I have at the same time?? As per my understood, for Apache::DBI connection pooling is based per server process. So, I guess as many server process you have, you can have db connection handle open at the same time.. AM I RIGHT HERE? Please clear my doubts on this... And thanks for your help ... Niral

#1 exists in the new CGI
#2 could be integrated with the new CGI with some amount of effort (though
I doubt it would be huge). Right now the sticky forms aspect works by
having the form generating object call $self->param to set defaults. If
this were changed to call $self->{state}->param and have what's in state
be either a CGI or Apache::Request object you'd be all set.
#3 is the new CGI
I really don't think we need yet another module doing what CGI does. The
people who've worked on the new version have done a very good job of
addressing the memory and speed concerns people had about the current
monolothic version. I think its much better to extend their work than to
redo it.

well the function that creates a popup menu is different
than the function that enables stickiness for a particular
instance of a popup menu. how's this for pseudo code:
--
package FormWidget;
sub popup_menu
{
# generate the html for a popup menu
}
package StickyForm;
my $pm1 = FormWidget::popup_menu('pm1', $r->param('pm1'));
my $pm2 = FormWidget::popup_menu('pm2', $r->param('pm2'));
--
obviously there is a lot more to making forms sticky than
that. but you get the gist of the general separation of
responsibilities.

Now that makes sense, in that it is more generic in nature. After all, I would hope that this will be a useful module to many people, not just Peter and I. When we get some time, Peter and I should sit down and try to come up with a v.01 API. Of course, all thoughts would be welcome.

No, my /CURRENT/ setup uses CGI.pm. I want to eliminate it entirely in
this new module, while not having to change any of my existing
application code. I would like to not change any lines like the ones
above when switching to the new module.

I personally have code that puts a CGI.pm object in the object ($self),
which is then used for both HTML generation AND fetching params AND
cookies.
For example, I have lines like 'my $val = $self->{CGI}->param('blah')'
as well as 'my $form = $self->{CGI}->popup_menu(-name=>'blah', ...)'.
The effect is to emulate CGI.pm, while being leaner & simpler.

Since you didn't read the docs, here they are (relevant bit highlighted):
% perldoc -f use
=item use Module LIST
=item use Module
=item use Module VERSION LIST
=item use VERSION
Imports some semantics into the current package from the named module,
generally by aliasing certain subroutine or variable names into your
package. It is exactly equivalent to

except that Module I be a bareword.

Better still:
eval {
die unless $ENV{MOD_PERL};
require Apache;
my $r = $Apache->request;
...
};
Then you've got no (at least much less than the above) run-time overhead.

writing code that works on machines with or without mod_perl
modperlers,
does it make sense if i put some mod_perl specific codes inside
an eval() so that the code runs on machines that have or haven't
mod_perl installed?
eval <<'MOD_PERL_CODE' if $ENV{MOD_PERL};
use Apache ();
my $r = Apache->request;
...
MOD_PERL_CODE
if i don't do so, perl will complain about Apache is not installed
on machines that doesn't have mod_perl installed.

I do not want a "last update wins" situation. This first criteria seems a tad odd to me. What business scenario is there for this? To me, when a user issues an update they expect that the record exists. In a way, if the record does NOT exist, then you are really going against your rule #2. That is, if they issue an update and the record no longer exists, then that is also a change to the record that someone did (a deletion) and you are effectively overriding someone elses deletion. >This is being done in an mod_perl/embperl/Apache::DBI environment. > >Suggestions or pointers to additional information would be greatly >appreciated. > >Peace. An application which implements #2 and is accelerated when used with mod_perl (Apache::Registry) and Apache::DBI is our latest version of WebDB. You may download a copy at http://www.extropia.com/ and click on download button at the top upper right)... If you want to read about it, the docs are located at http://www.extropia.com/docs/webdb/. Actually it was all generated using Stas Bekman's mod_perl guide generator (except using my pods instead of Stas's mod_perl guide pods) The WebDB will do #2 for you and, in fact, allows configuring the strategy of updates... eg you can choose to check all fields for changes, a subset of fields for changes, or just "key fields" for changes... similar to the PowerBuilder DataWindow model of handling client-server updates. This is done through the use of Extropia::DataSource which is a library that abstracts this stuff away. By default, WebDB is distributed to be configured to use Extropia::DataSource::File, but you just need to take out the file specific stuff from the config and then replace -TYPE => 'File' with -TYPE => "DBI" and add -DSNAME => 'dbi:yourdatabase etc..." and you are pretty much off and running. So the caveat is that the app is configured by default to work on any CGI/Perl environment. But it has been architected to take advantage of mod_perl's benefits (eg Apache::DBI) by just changing config parameters in the setup file. Since all the new extropia apps follow this common architecture, we have documented the mod_perl specific tuning issues in the Advanced Chapter of the Extropia Apps Guide (a supplement to the WebDB Guide) located at http://www.extropia.com/docs/extropia_app/ If you don't like WebDB itself and need to write your own logic, then you may want to just use Extropia::DataSource by itself (which implements the logic you want as an object but no CGI workflow exists around it). The documentation and code for that set is located at http://www.extropia.com/ExtropiaObjects/ Hope this helps, Gunther __ Gunther Birznieks ([EMAIL PROTECTED]) Extropia - The Web Technology Company http://www.extropia.com/
